Description

Fan blade

Technical Field

The utility model relates to the technical field of fan blades, in particular to a fan blade.

Background

The fan blades are used for a wide variety of purposes, and the purpose of the fan blades is to generate wind power by driving the fan blades to rotate through a power source, and the wind power can be used for heat dissipation or generating propelling or lifting force.

The current fan blade still has a large lifting space in the process of power conversion.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model aims to provide the fan blade which is reasonable and simple in structure, strong in realization, capable of reducing energy consumption and improving kinetic energy conversion.

In order to achieve the purpose, the utility model provides the following technical scheme:

a fan blade comprises a hub and a plurality of blades distributed on the outer circumference of the hub, the top of each blade is connected with an outer ring, two adjacent blades are partially overlapped, and the area of the overlapped part is 1/5-1/2 of the blade.

The utility model is further configured to: the middle part of each blade is connected with an inner ring together, so that the inner ring divides the blade into two sections.

The utility model is further configured to: the top of the blade is arc-shaped, and the width of the blade is gradually increased from the joint of the blade and the hub to the outer ring direction.

Compared with the defects of the prior art, the utility model has the beneficial effects that:

through the overlapping arrangement between the installation outer ring and the adjacent blades, the wind power is reduced to be scattered out from the outer peripheral side of the fan blade, the concentrated wind power is achieved, the energy consumption is reduced, and the conversion rate of the kinetic energy is improved.

Detailed Description

The top of the blade is provided with the ring, so that the condition that wind power generated by the fan blade is dispersed to the outer circumference when the fan blade rotates is reduced, and the conversion of kinetic energy is further improved.

The fan blade can be used in turbine engine, dust collector, small plastic fan blade in equipment, water pump propeller, ship or helicopter

The first embodiment is as follows: as shown in fig. 1, 2 and 5, the fan blade specifically includes: the wind turbine comprises a hub 1 and a plurality of blades 2 distributed on the outer circumference of the hub 1, wherein the blades 2 are obliquely fixed on the hub 1.

In order to facilitate the connection between the hub 1 and the power component, the inner peripheral wall of the hub 1 is provided with a clamping groove. The hub 1 and the blades 2 can be integrally formed by plastic injection; can be formed by welding and fixing metal.

The outer ring 3 is connected to the tip of each blade 2. The outer ring 3 can be made of plastic or metal. The blades 2 and thus the outer ring 3 can be connected by heat fusion or by welding.

Two adjacent blades 2 are partially overlapped, i.e. one blade 2 is partially arranged above the other blade 2, and the area of the overlapped part 20 is 1/5-1/2 of the blade 2.

When the area of the overlapping portion 20 is 1/5 of the blade 2, the fan blade can be used on a fan, a computer radiator, a ship or a helicopter.

When the area of the overlapping portion 20 is 1/4 of the blade 2, the fan blade can be used on a fan, a computer radiator or a ship or a helicopter.

When the area of the overlapping portion 20 is 1/3 of the blade 2, the fan blade can be used on a fan, a computer radiator or a ship or a helicopter.

When the area of the overlapping portion 20 is 1/2 of the blade 2, the fan blade can be used on a turbine engine, a dust collector or an air conditioner compressor.

The middle part of each blade 2 is connected with an inner ring 4 together, so that the inner ring divides the blade 2 into two sections. The inner ring 4 and the outer ring 3 are of the same construction. When the blades 2 are assembled, one group 22 is connected with the inner ring 4 and the hub 1, the other group 21 is connected with the inner ring 4 and the outer ring 3, the inner ring 4 is arranged to improve the generation of wind power, so that the wind can be gathered inwards more, and the conversion of kinetic energy is improved. The two sets of blades 2 are arranged in an extending relationship to ensure stability during rotation.

The top of the blade 2 is arc-shaped, and the width of the blade 2 increases progressively from the connection part of the blade and the hub to the outer ring direction.

Example two: as shown in fig. 3, 4 and 5, the fan blade specifically includes: the hub 101 and a plurality of blades 2a distributed on the outer circumference of the hub 101, the blades 2a are fixed on the hub in an inclined way.

The outer ring 31 is connected to the tip of each blade 2 a. The outer ring 31 can be made of plastic or metal. The blades 2a and the outer ring 31 can be connected by hot-melting or welding.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and those skilled in the art should be able to make general changes and substitutions within the technical scope of the present invention.
