DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein.

[0034] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0035] In the description of the embodiments of the present application, it should be understood that the terms "inside", "outside", "top", "bottom", "front", "back", etc. indicating the orientation or position relationship (if any) are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0036] During the installation of a wind turbine tower, multiple cylinder sections need to be assembled into the tower body. Due to the large diameter of the cylinder sections, they usually need to be assembled outdoors. In order to avoid the influence of wind factors on site, wind-blocking walls are usually used to block the wind. However, when it rains or snows, the wind-blocking walls cannot prevent the erosion of rain and snow, which affects the assembly of the cylinder sections and seriously affects the installation progress.

[0037] The embodiment of the present application provides a protective device for wind power tower assembly, which can prevent rain and snow from affecting the assembly of cylinder sections. The present application will be further described below in conjunction with the accompanying drawings.

[0038] like Figure 1 As shown, Figure 1 A schematic diagram of the structure of a protective device for wind tower assembly provided in an embodiment of the present application.

[0039] An embodiment of the present application provides a protective device for assembling a wind tower, including a main frame 100 , a top frame 200 , at least one first blocking member 300 , and at least one second blocking member 400 .

[0040] The first blocking members 300 are arranged end to end on the main frame 100 , and the first blocking members 300 surround and form an operation space. At least one of the first blocking members 300 is provided with an opening 500 for the tower body to enter and exit the operation space.

[0041] The top frame 200 is disposed on the top of the main frame 100 , and each second blocking member 400 is disposed on the top frame 200 . The second blocking member 400 is used to close the top of the operating space.

[0042] An operating space is jointly constructed on the main frame 100 and the top frame 200 by the first blocking member 300 and the second blocking member 400. The first blocking member 300 is arranged on the side of the operating space to block the influence of wind, and the second blocking member 400 is arranged on the top of the operating space to block the influence of rain and snow, thereby avoiding the influence of wind and rain and snow factors during the tower body welding process.

[0043] It should be noted that the second blocking member 400 can also prevent debris such as leaves from entering the enclosed space.

[0044] Among them, the main frame 100 is welded with 100*100*4.5 equal-angle steels, and the top main frame 100 is welded with 50*50*3 equal-angle steels. The weight of the main frame 100 or the top frame 200 can be adjusted by the thickness of the angle steel according to actual needs.

[0045] The main frame 100 can also use square tubes and rectangular tubes as substitute materials for angle steel. For example, a square tube of 100*100*5 is used to replace an angle steel of 100*100*4.5.

[0046] Exemplarily, the area of ​​the first blocking member 300 is equal to the area of ​​the side wall on one side of the main frame 100, each first blocking member 300 covers each side wall of the main frame 100, and the first blocking members 300 on two adjacent side walls are connected to avoid the influence of wind factors.

[0047] Exemplarily, when the main frame 100 is in a cube shape or a rectangular shape, the main frame 100 has four side walls in total, and the four first blocking members 300 are welded to the four side walls respectively, and the edges of two adjacent first blocking members 300 are welded together to form a closed operating space.

[0048] For example, when the main frame 100 is a hexagonal body, the main frame 100 has six side walls, six first blocking members 300 are welded to the six side walls respectively, and the edges of two adjacent first blocking members 300 are welded together to form a closed operating space.

[0049] The main frame 100 supports the first blocking member 300 . The first blocking member 300 is made of a lightweight material. The shape of the main frame 100 can be adjusted according to actual conditions so that the first blocking member 300 forms a closed operating space.

[0050] Since the length of the existing wind power tower is 5-7 meters and the diameter is 2-4 meters, the operating space formed by the main frame 100 and the first blocking member 300 is 5-7 meters long and 3-4 meters wide. The height is 5-7 meters, and the size of the main frame 100 and the first blocking member 300 are adjusted according to the actual situation. There needs to be a gap of 0.5-1 meters between the manufactured operating space and the wind power tower section so that the staff can enter and operate.

[0051] Exemplarily, when the main frame 100 is in a cube or rectangular shape, an opening 500 is provided on one side wall of the main frame 100 or openings 500 are provided on two opposite sides, wherein 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 operating 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 member 400 is installed on the top frame 200, the second blocking member 400 can completely cover the top of the operating space to prevent rain and snow from entering the operating space.
