Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a protective device for a wind power generation chassis. Background Art

[0002] Wind power generation refers to the conversion of wind's kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source that has been used by people for a long time. People are interested in how to use wind to generate electricity. Wind power generation is very environmentally friendly and has huge wind energy reserves, so it is increasingly valued by countries around the world.

[0003] Existing wind turbines are all installed outdoors in uninhabited areas, and the wind turbine box is also directly exposed to the air. Since there are many birds outdoors, the curvature of the top of the wind turbine box is small, and birds are easy to land on it. Birds will poop on the top of the wind turbine box. Since bird poop is corrosive, it will cause corrosion damage to the wind turbine box over time. Therefore, a protective device for a wind turbine box is proposed. Utility Model Content

[0004] The utility model aims to solve the problems raised by the background technology and proposes a protective device for a wind power generation chassis.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A protective device for a wind power generation chassis includes an arc-shaped protective plate, and mounting mechanisms are provided on both sides of the bottom of the arc-shaped protective plate; a bird-proofing top is fixedly provided on the top of the arc-shaped protective plate, and the top of the bird-proofing top adopts a pointed structure, and both sides of the bird-proofing top adopt an arc-shaped inner concave surface structure, and the top of the bird-proofing top is provided with a plurality of evenly distributed avoidance grooves.

[0007] Preferably, the mounting mechanism comprises a mounting plate and mounting bolts, the mounting plate is fixedly disposed on the end of the arc-shaped protective plate, and the mounting bolts are inserted into the mounting plate.

[0008] Preferably, the mounting plate is fixedly connected to the connecting portion between the chassis and the column by means of mounting bolts.

[0009] Preferably, the inner side wall of the arc-shaped protective plate is provided with a plurality of auxiliary support mechanisms, and the auxiliary support mechanisms include a support plate and a support column, the support column is fixedly arranged between the support plate and the arc-shaped protective plate, and the support column adopts an eight-shaped structure.

[0010] Preferably, the support plate is a curved plate, and the curvature of the support plate matches the curvature of the chassis.

[0011] Preferably, the arc-shaped protective plate, bird-falling prevention top, mounting mechanism and auxiliary support mechanism are all made of stainless steel.

[0012] Compared with the prior art, the utility model provides a protective device for a wind power generation chassis, which has the following beneficial effects:

[0013] 1. The protective device of the wind power generation chassis has an anti-bird falling top arranged on the top of the arc-shaped protective plate. The arc-shaped protective plate can wrap and protect the outer wall of the chassis. At the same time, the top of the anti-bird falling top adopts a pointed structure, which can prevent birds from standing, and the avoidance groove will also make it impossible for birds to stand on the pointed structure with both feet at the same time, thereby preventing birds from defecating on the surface of the arc-shaped protective plate. In addition, both sides of the anti-bird falling top are arranged with an arc-shaped inner concave surface structure. Even if birds defecate on the side wall of the anti-bird falling top during flight, the bird droppings will fall along the side curvature of the anti-bird falling top. Even if there is a small amount of bird droppings remaining, it will be washed away by rain in the rainy season, thereby preventing the arc-shaped protective plate and the anti-bird falling top from being corroded by bird droppings.

[0014] 2. The protective device of the wind power generation chassis is provided with a support plate and a support column on the inner wall of the arc-shaped protective plate. When the arc-shaped protective plate is wrapped around the outer wall of the chassis, the support plate fits with the outer wall of the chassis, and the support column can play a supporting role, thereby increasing the stability of the arc-shaped protective plate on the outer wall of the chassis.

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model adopts the structure of arc-shaped protective plate and anti-bird falling top, so that birds and bird droppings will not fall on the top of the chassis, avoiding the phenomenon of bird droppings causing corrosion to the chassis, thereby improving the protection effect of the chassis.
