Description

The utility model relates to the field of shipbuilding, and more specifically to special devices of research vessels, and can be used to automatically launch autonomous buoy stations at a predetermined interval.

Currently, various types of technical devices are widely used for launching works, ocean research and search operations.

Reliable and efficient use of devices largely depends on the presence of special launching mechanisms on the carrier vessel that ensure safe launching and lifting operations in the open sea. For this purpose, general cargo devices (cranes, arrows, portals) are used, however, their use is associated with severe restrictions on weather conditions.

Well-known devices for carrying out tripping operations of underwater vehicles, including portals, cranes, as well as a U-shaped or L-shaped beam falling overboard with a pulley through which a cable-cable from a cable winch is passed. However, the preparations for the descent are carried out on an open deck, which imposes a number of limitations on the use of such devices, caused by meteorological conditions.

The closest technical solution is a device for carrying out tripping operations of scientific research devices, (invention No. 201390, 1994 of the Russian Federation, B.N. Toropov, N.P. Polovets; Device for lowering and raising a floating object - analogue).

The disadvantages of this analogue are:

- a complex system of cables for lowering the rise;

- the use of kilblocks or trolleys;

- significant mass of the device;

- limitation of work with pitching;

- a large number of manual operations;

- significant time spent on maintenance.

The objectives of the proposed utility model are: increasing the efficiency of launching research buoy stations by providing the ability to conduct operations indoors, improving the safety of the crew and lander, eliminates the use of other cargo means during the descent of equipment, the possibility of launching the equipment in automatic mode and performing work in difficult weather conditions.

The tasks are solved by using the utility model of an automatic device for launching overboard with a specified interval of autonomous buoy stations, which contains a cartridge block consisting of two parts - the upper part loaded with buoy stations and the lower equipped with an onboard waterproof closure that opens together with the lower part of the block cassettes with the help of a hydraulic cylinder, guide rollers along the entire length of the cassette block of the device provide movement of the buoy stations, excluding mechanical resulting damage, lowering buoy station system remote control with a predetermined interval. The automatic device is placed in a room inside the ship’s hull, which is equipped with an inclined drain, which ensures the discharge of seawater that has got overboard.

The essence of the utility model is illustrated by drawings, where in FIG. 1-2 - a General view of the proposed device, in FIG. 3-4 - presents the principle of operation of the device for the descent of buoy stations.

The automatic device consists of:

1 - block cassettes;

2 - a hydraulic cylinder;

3 - waterproof side closure;

4 - upper guide;

5 - lower guide;

6 - side roller guides;

7 - rubberized gasket;

8 - remote control system;

9 - waterproof door;

10 - inclined discharge;

11 - a directing trench;

12 - antenna;

13 - rubber insert;

14 - hinge insert;

15 - sealing gaskets;

16 - zadrayki;

17 - the side of the vessel;

18 - buoy station.

The cartridge block 1 is located in the hull of the vessel. The cartridge block has upper guides 4, firmly fixed to the block 1 and lower guides 5, connected with the side closure 3 and opened together with the hydraulic cylinder 2 by the waterproof side closure 3.

In the upper part of the device of the cassette unit 1 along the entire length there are side roller guides 6, which provide additional fixation of the buoy stations 18 in the storage position and directional movement during the descent of the buoy stations 18.

When the vessel is rocking for additional depreciation and excluding damage to the buoy stations 18 between themselves located in the cassette block 1, rubberized gaskets 7 are installed between the buoy stations.

The cassette unit 1 is equipped with a remote control system 8. The system allows the autonomous buoy stations 18 to be launched at a predetermined time interval, excluding the reset of two or more buoy stations simultaneously.

For maintenance and visual inspection of the entire device, access to the room is provided through a special waterproof door 9.

During the discharge of buoy stations 18 during sea waves, seawater may enter the room through an open waterproof side closure 3. In order to prevent water accumulation in the lower part of the cassette block, an inclined drain 10 is provided, which allows water to drain overboard without residues.

To avoid damage to the buoy station 18 when it moves along the roller guides in the cartridge block, a guide chute 11 is provided in which, when charging the buoy stations 18, the antenna 12 of the buoy station 18 is inserted into the cartridge block 1 in advance. The guides are connected to the upper and lower movable parts by a flexible rubber insert 13, which allows the unhindered movement of the antenna 12 along the entire path of movement of the displaced station 18.

The upper 4 and lower 5 guides, responsible for the direct movement of the buoy station 18 along the block of cassettes 1, are interconnected by a hinge insert 14 for the smooth movement of the buoy stations 18.

After completing all the triggering operations, the lower part of the cartridge unit 1 together with the side closure 3, using the hydraulic cylinders 2, is closed in the stowed position.

In the closed position, the side closure 3 for sealing at the edges has a sealing gasket 15, which, when closed by hydraulic cylinders 2, is tightly pressed against the hull 17, providing isolation from the influence of external weather conditions.

In the closed position, the side closure 3 is fixed by zadraki 16, giving additional downforce.

At the end of the hoisting operations, the vessel is removed from the positioning point and proceeds to the next place of research.

The proposed device for launching autonomous buoy stations allows you to:

- minimize the number of manual operations;

- eliminate the need to use a work boat and other cargo means during the descent of the buoy stations;

- ensure safe launching operations on the high seas;

- reduce the risk of damage to buoy stations and crew injuries.

In addition, the proposed device is not affected by the environment due to the location of the main mechanisms in a closed room.

Thus, the efficiency of launching operations is increased, the number of manual operations is minimized, the safety of the crew and the equipment being launched, the ability to carry out equipment descent in automatic mode and performing work in difficult weather conditions is ensured, which ensures safe launching operations on the high seas.
