[0036] During the installation of the wind power tower, multiple barrel segments need to be assembled into the tower body. Since the diameter of the barrel segment is large, it is usually assembled outdoors. In order to avoid the influence of the on-site wind factor, a wind blocking wall is usually used to block the wind. However, when it is raining and snowing, the wind blocking wall cannot block the erosion of rain and snow, affecting the assembly of the barrel segment, and seriously affecting the installation progress.

[0037] The embodiment of the present application provides a protection device for wind power tower assembly, which can prevent the influence of rain and snow on the assembly of the barrel segment. The present application will be further described below with reference to the accompanying drawings.

[0038] As shown in FIG. 1, wherein Figure 1 the structure diagram of the protection device for wind power tower assembly provided by the embodiment of the present application. Figure 1

[0039] The protection device for wind power tower assembly provided by the embodiment of the present application comprises a main frame 100, a top frame 200, at least one first blocking piece 300 and at least one second blocking piece 400.

[0040] Each first blocking piece 300 is arranged on the main frame 100 in a head-to-tail manner, each first blocking piece 300 surrounds to form an operation space, and at least one first blocking piece 300 is provided with an opening 500 for the tower body to enter and exit the operation space.

[0041] The top frame 200 is arranged at the top of the main frame 100, each second blocking piece 400 is arranged on the top frame 200, and the second blocking piece 400 is used to close the top of the operation space.

[0042] ​The first blocking piece 300 is arranged on the side of the operation space and is used to block the influence of wind, and the second blocking piece 400 is arranged on the top of the operation space and is used to block the influence of rain and snow, so that the influence of wind and rain and snow on the welding of the tower body is avoided.

[0043] It should be noted that the second blocking piece 400 can also prevent leaves and other sundries from entering the enclosed space.

[0044] The main body frame 100 is welded by using 100*100*4.5 equilateral angle steel, and the top main body frame 100 is welded by using 50*50*3 equilateral angle steel, and the thickness of the angle steel can be adjusted according to actual needs to adjust the weight of the main body frame 100 or the top frame 200.

[0045] The main body frame 100 can also use square tubes and rectangular tubes as alternative materials for angle steel. For example, 100*100*5 square tubes are used instead of 100*100*4.5 angle steel.

[0046] For example, the area of the first blocking piece 300 is equal to the area of the side wall of one side of the main body frame 100, each first blocking piece 300 covers each side wall of the main body frame 100, and the first blocking pieces 300 on the adjacent two side walls are connected, so as to avoid the influence of wind.

[0047] For example, when the main body frame 100 is a cube or a cuboid, the main body frame 100 has four side walls, and four first blocking pieces 300 are welded on the four side walls, respectively, and the edges of the adjacent two first blocking pieces 300 are welded together to form an enclosed operation space.

[0048] For example, when the main body frame 100 is a hexagonal prism, the main body frame 100 has six side walls, and six first blocking pieces 300 are welded on the six side walls, respectively, and the edges of the adjacent two first blocking pieces 300 are welded together to form an enclosed operation space.

[0049] The main body frame 100 supports the first blocking piece 300, the first blocking piece 300 is made of light material, and the shape of the main body frame 100 can be adjusted according to actual conditions, so that the first blocking piece 300 forms a closed operation space.

[0050] The length of the existing wind turbine tower is 5-7 meters, and the diameter is 2-4 meters. Therefore, the operation space formed by the main frame 100 and the first blocking piece 300 has a length of 5-7 meters and a width of 3-4 meters. The height is 5-7 meters, and the size of the main frame 100 and the first blocking piece 300 is adjusted according to the actual situation. The operation space needs to have a gap of 0.5-1 meter with the wind turbine cylinder segment so that the staff can enter the operation.

[0051] For example, when the main frame 100 is a cube or a cuboid, an opening 500 is arranged on one side wall of the main frame 100 or opposite sides are both provided with an opening 500, and the length and width of the opening 500 are greater than the diameter of the tower body, so as to facilitate the tower body to enter the operation space.

[0052] It should be noted that the shape of the top frame 200 matches the shape of the main frame 100, the top frame 200 is welded to the top of the main frame 100, and when the second blocking piece 400 is installed on the top frame 200, the second blocking piece 400 can completely cover the top of the operation space to prevent rain and snow from entering the operation space.
