Description

Sea energy driving, power generating and piling semi-submersible ship

Technical Field

The utility model relates to the field of ships, in particular to a sea energy driving, power generating and piling semi-submersible ship.

Background

The semi-submersible ship is also called a semi-submersible mother ship, and is used for submerging a cargo loading deck by adjusting ballast water of the semi-submersible ship so as to float specific cargo (such as barges, yachts, ships, drilling platforms and the like) to be carried from a specified position onto the cargo loading deck of the semi-submersible ship and transport the cargo to the specified position. However, the existing semi-submersible vessel basically sails by adopting the mode that the traditional internal combustion engine drives the propeller to propel, the fuel used by the internal combustion engine needs to be supplemented in time, the requirement on the supply of the vessel is extremely high, and once the vessel encounters the weather of stormy winds and rainstorms, the supply of the marine supply is difficult to carry out.

When the traditional pile driving ship drives piles at sea, the ship body can greatly shake once meeting the condition of large wind waves due to the fact that the ship body is not deep into water, and pile driving operation cannot be carried out. Thus, the operation of a conventional pile driving vessel is greatly affected by the weather at sea. The traditional piling ship has piling equipment from an internal combustion engine, and the piling process is high in energy consumption and long in time consumption, so that materials such as fuel and the like need to be conveyed to the piling ship through other supply ships frequently. However, when the sea state is unreasonably changed, the replenishment time of the replenishment ship is easily delayed by the influence of weather, and the replenishment cost is high.

The ocean has huge renewable energy sources, and the collectable energy of the ocean mainly comprises ocean wave energy, tidal energy, wind energy and the like. The ship sailing by utilizing the inherent energy of the ocean is a constantly-striving target of human beings, the technology is mature, the history is long, and sailing ships are used, but the research on the ship connection theory for sailing by utilizing other renewable energy sources except wind energy of the ocean is difficult to see. The sailing boat needs a huge sail to drive due to too small energy density of wind energy, is greatly influenced by wind force, and cannot actively and quickly drive. Therefore, sailing boats cannot meet the requirements of modern marine transportation and can only be used in a very small amount for sports or tourism.

In addition, the driving mode of the ship at present basically adopts a propeller propulsion system. However, propeller propulsion systems have the following problems in use: 1) the problem that seawater enters the engine room along the transmission shaft exists; 2) fuel and an engine are needed, the fuel cost is high, the pollution is large, the working noise of the engine is large, and when the propeller stirs water flow, the water flow collides with the propeller with a hard surface, large noise is also generated; 3) when a ship using a traditional fuel oil propeller propulsion system advances, the head and the tail of the ship form a water level difference with a high head and a low tail, and the larger the speed of the ship is, the larger the water level difference is, so-called an uphill effect is formed; meanwhile, the bow of the ship is increased, so that the projected area of water resistance is increased and the jolt of the ship is aggravated.

1. because the influence of the fluctuation of sea surface waves on the hull below the sea surface is small, when the pile is required to be driven, most of the ship is submerged below the sea surface, the hull is stable at the moment and is not easy to shake along with the waves, the pile driving operation is carried out at the moment, the pile driving accuracy is high, and the pile driving can be normally carried out.

2. The sea water is pumped up by utilizing the ocean current sea wave energy collector and the water pumping and pressurizing device to form high-pressure water for power generation, the electric energy can directly or indirectly supply power to the pipe sinking pile driver through the storage battery, the pipe sinking pile driver does not need to provide kinetic energy through a fuel engine, energy conservation and environmental protection are achieved, the ocean current sea wave energy collector can continuously collect ocean current sea wave energy, continuous piling is ensured, and the operation progress is greatly accelerated.

3. The high-pressure water is mainly generated by the ocean current sea wave energy collector and the water pumping and pressurizing device, the energy of the ocean current sea waves is fully utilized to generate the high-pressure water, the use of other energy sources is not needed or reduced, and the energy-saving effect is good. Wherein, the dynamic duckweed can fluctuate up and down along with the sea waves to generate power and drive the first piston cylinder structure to extract seawater and pressurize; and the ocean current in the horizontal flow direction can drive the ocean current driving wheel submerged below the sea surface to rotate and drive the membrane-blowing box to pump seawater and pressurize the seawater. The pressurized seawater can be respectively supplied to the high-pressure jet flow spray head and the hydraulic power generation system according to the requirement. Because the ocean current and ocean wave energy is huge, especially under the condition of strong wind and strong waves, a large amount of energy can be collected by the ocean current and ocean wave energy collector to be used as the driving energy and the power generation of the semi-submersible ship, basically no fuel is needed, and no fuel supply is needed at sea, so that the single sailing time can be greatly prolonged, the semi-submersible ship can be favorable for carrying out long-term operation at sea, the special requirements of island power supply, sea surface operation power supply, marine foundation piling construction and the like with great difficulty are met, and the development and the utilization of the sea and the island are easier and more efficient.

In addition, because the main water suction port is positioned at the front part of the ship and the high-pressure jet flow spray head is positioned at the rear part of the ship, the water suction at the bow reduces the water level at the bow, the water spray at the stern raises the water level at the stern to form a so-called downhill effect, the effect is offset with the uphill effect formed by the ship body propelled in water, the water resistance projection area is reduced, the bump of the ship is reduced, and therefore the ship can run smoothly and save energy.

The transmission rack sliding block 3 is movably connected with the piston connecting rod structure 2.

In this embodiment, the slider guide 6 includes a substrate 61. The guide structure includes a bar-shaped guide plate 62 and a positioning slide pin 33 movable around an outer side wall of the guide plate 62. The strip-shaped guide plate 62 is vertically arranged, and the upper end and the lower end of the strip-shaped guide plate are arranged in an arc shape. The guide plate 62 is provided on the side surface of the base plate 61, and the positioning slide pin 33 is provided on the side surface of the slider main body 31. The guide plate 62 and the positioning slide pin 33 are provided in two sets, respectively, on both sides of the engagement rack 32. Both sides of the base plate 61 are provided with a welding port 63 and an auxiliary welding plate 64, and the auxiliary welding plate 64 is welded with the side surface of the slide rail 5.

The piston connecting rod structure 2 is provided with a first connecting rod 21 which is transversely arranged, and the first connecting rod 21 is transversely connected with the sliding block main body 31 in a sliding manner.

Two second cylinder bodies 1 are arranged in each basic assembly, the two second cylinder bodies 1 are symmetrically arranged on two sides of the gear 4, eccentricity is avoided, and smooth operation and durable use of the reciprocating pump are guaranteed. Wherein, two ends of the first connecting rod 21 are respectively connected with the upper ends of the piston connecting rod structures 2 of the second cylinder bodies 1 at two sides.

The number of the basic assemblies is even number such as 2, 4, 6, and the cylinder stroke of the piston connecting rod structure 2 in the two corresponding basic assemblies is arranged in opposite phase. In the present embodiment, the number of the basic components is 2, and when the two piston rod structures 2 of one of the basic components are in the fully-pulled-out state, the two piston rod structures 2 of the other basic component are in the fully-pressed-in state. The power shaft 41 is one and the number of the gears 4 corresponds to the number of the basic components. In each basic assembly, the back side of the base plate 61 of the slide block guide frame 6 is provided with two symmetrically arranged rib plates 65, and the rib plates 65 of the two basic assemblies are oppositely arranged and fixedly connected through a connecting plate 10.

The drive motor 12 may be powered by the battery of the vessel 22. Because the positioning sliding pin 33 always moves around the outer side wall of the guide plate 62, the gear 4 is always engaged with the meshing rack 32 which is annularly arranged on the transmission rack sliding block 3, the transmission rack sliding block 3 can move up and down in a reciprocating manner to a large extent, and the piston connecting rod structure 2 is driven to move up and down. In the process, when the gear 4 passes through the arc transition rack 322 of the meshing rack 32, the transmission rack slider 3 can also transversely move relative to the piston connecting rod structure 2, so that the gear 4 is switched between the two linear meshing racks 321, and the aim of up-and-down movement of the piston connecting rod structure 2 can be achieved without reversing and rotating the gear 4. In the process that the piston connecting rod structure 2 moves up and down, when the piston connecting rod structure 2 moves up, negative pressure is generated in the second cylinder body 1, seawater is sucked into the second cylinder body 1 by the water suction port 7, and at the moment, the second one-way valve 81 is closed; when the piston connecting rod structure 2 moves downwards, the water pressure in the second cylinder body 1 is increased, the first one-way valve 71 is closed, the second one-way valve 81 is opened, the high-pressure seawater in the second cylinder body 1 is conveyed to the high-pressure pipe 25 of the high-pressure jet flow driving system of the ship 22 from the high-pressure water outlet 8, the high-pressure jet flow nozzle 24 at the tail end of the high-pressure pipe 25 sprays water to the back of the ship body, and the ship 22 is driven to advance by the reverse thrust of the water.

When the rated high-pressure water pressure of the jet flow driving system is 10MPa, and the tail nozzle of the high-pressure jet flow nozzle 24 is D50, the following can be calculated: the tail jet speed is 100M/s, the maximum thrust is 1.96T, and the maximum water jet quantity is 0.196M³/s。

When the rated high-pressure water pressure of the jet flow driving system is 12MPa, and the tail nozzle of the high-pressure jet flow nozzle 24 is D100, the following can be calculated: the tail jet speed is 120M/s, the maximum thrust is 9.4T, and the maximum water jet quantity is 0.94M³/s。

Generally, the rated pressure of high-pressure water is about 10MPa, and the main power is high-pressure water generated by the sea wave energy collector. The high-pressure water pipe network system achieves high water pressure, large pipe diameter, low flow velocity and low energy consumption.

The implementation process of two main functions of the sea energy driving and power generation semi-submersible ship is described by taking high-pressure water rated pressure of 10MPa as an example:

(1) the sea wave energy is utilized to realize the power generation function:

when the ship is parked or sailed, the second layer of the ship is completely submerged so as to collect the sea energy, and the high-pressure water generated by the energy collector is used for driving the high-pressure water wheel generator to generate electricity.

The hydraulic generator generally adopts more than 3, when the water pressure is more than 10.1MPa, a hydraulic generator is automatically opened through a self-control electromagnetic valve. When the water pressure is less than 9.9MPa, a hydraulic generator is automatically turned off through the automatic control electromagnetic valve, so that the function of high-quality power generation is realized.

(2) The high-pressure water is utilized to realize the driving function:

the ship moves by adopting a high-pressure water jet driving system, high-pressure water mainly comes from a sea wave energy collector, and only under special conditions, the high-pressure water is started to be actively supplemented by an electricity storage driving large-stroke reciprocating pump. The ship thrust is controlled through controlling the flow control electromagnetic valve, the tail spraying direction is controlled, and the ship course is controlled, so that the ship navigation driving function is realized.

The realization of the piling function:

the seawater energy is utilized to supply power to construction equipment such as a pile driver, a crane, a sludge pump and the like by self-power generation, and four layers are used as construction sites. The construction process is as follows:

(1) the semi-submersible ship floats, falls and adjusts the one-layer or three-layer slidable sea surface pile sinking stabilizing clamps to clamp the pile tightly.

(2) And (3) sinking the semi-submersible ship to the sea level when the semi-submersible ship is berthed for power generation, adjusting the position of the ship to enable the pile to be aligned to the piling position of the seabed, and starting piling construction.

(3) And after the pile is completely driven, cutting the pile at a slightly higher position of the sea level. The semi-submersible ship floats and realizes the separation of the ship pile through the ship pile separation channel.

The whole piling process realizes the all-water construction, and the sea wave energy self-generation solves the problem of power energy of offshore construction; the superior stability and the free floating and sinking characteristic of the semi-submersible ship hung with the full sea wave energy collector ensure that the piling operation in the sea with high wind and severe waves can be smoothly implemented
