[0040] As mentioned in the background technology: Wind turbine towers are an important component that supports wind turbine generators for high-altitude power generation. Onshore wind turbine towers are generally divided into 4 sections, with the diameter of each section typically ranging from 4 to 6 meters, and are mainly connected by welding.

[0041] The tower is welded with a sealing platform. When welding the sealing platform, the tower needs to be placed horizontally first, and then the sealing platform is moved into the tower. The welder uses auxiliary tools to weld the sealing platform onto the tower.

[0042] However, the flatness of the sealing platform after welding cannot be guaranteed, and the tower has a large deformation after welding, which affects the performance of the tower itself.

[0043] To address the aforementioned technical problems, this application provides a welding protection device for a wind turbine tower sealing platform. This device consists of a protective frame and at least three fixing components. The protective frame is placed horizontally on the ground, and the fixing components are installed at intervals on the protective frame. When the sealing platform needs to be welded to a cylinder segment, the cylinder segment is placed vertically on top of the protective frame. The bottom of the cylinder segment is then fixed using the fixing components, and the sealing platform can then be welded. The horizontal placement of the sealing platform facilitates adjustments to its flatness by the workers. Furthermore, the protective frame and fixing components secure the lower end of the cylinder segment, thereby strengthening its structural strength during welding and reducing deformation, thus ensuring the performance of the cylinder segment after welding.

[0044] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0045] refer to Figure 1 and Figure 2This application discloses a welding protection device for a wind turbine tower sealing platform, which is used to cooperate with the cylinder section 400. The protection device includes a protective frame 100 and at least three fixing components 200.

[0046] The protective frame 100 is placed horizontally on the ground and is configured to be located at the bottom of the vertically arranged cylindrical section 400.

[0047] Fixing components 200 are spaced apart on the protective frame 100, and the fixing components 200 are configured to fix the bottom of the cylindrical section 400.

[0048] When welding the sealing platform onto the cylinder section 400, the cylinder section 400 is first placed vertically (that is, the cylinder section 400 is placed in a vertical direction), then the sealing platform is placed in a suitable position on the cylinder section 400, the flatness of the sealing platform is adjusted (that is, the levelness of the sealing platform plane is adjusted), and then the workers weld the sealing platform.

[0049] For example, there are 6 fixing components 200, which are evenly spaced around the circumference so that the 6 fixing components 200 fix the bottom of the cylinder segment 400 respectively, thereby ensuring the strength of the fixing components 200 in fixing the bottom of the cylinder segment 400.

[0050] For example, the fixing assembly 200 includes two clamping plates and a screw. One clamping plate is fixed to the protective frame 100, and the other clamping plate is slidably disposed on the protective frame 100. The screw is threaded through one of the clamping plates and is rotatably connected to the other clamping plate. By rotating the screw, the two clamping plates can be moved closer or further apart, thereby fixing or opening the bottom of the cylinder section 400.

[0051] By adopting the above technical solution, when it is necessary to weld the sealing platform onto the cylinder section 400, the cylinder section 400 is arranged vertically and placed above the protective frame 100. Then, the bottom of the cylinder section 400 is fixed using the fixing component 200, and then the sealing platform can be welded. At this time, the sealing platform is arranged horizontally, which makes it easy for the staff to adjust the flatness of the sealing platform. Moreover, the protective frame 100 and the fixing component 200 fix the lower end of the cylinder section 400, thereby strengthening the structural strength of the cylinder section 400 during the welding process, reducing the deformation of the cylinder section 400 during the welding process, and ensuring the performance of the cylinder section 400 after welding.

[0052] In some embodiments, the protective frame 100 includes at least three protective plates 110, with adjacent protective plates 110 connected end to end to form a frame, and the fixing components 200 are disposed at the corners of the frame.

[0053] For example, there are 6 protective plates 110, which are connected end to end in sequence to form a regular hexagonal frame.

[0054] By adopting the above technical solution, and by setting at least three protective plates 110 and splicing them together to form a frame, the production cost of the protective frame 100 is reduced.

[0055] In some embodiments, the protective frame 100 further includes at least three reinforcing plates 120 located inside the frame, with one end of each reinforcing plate 120 connected to an end corner of the frame, and the other end of each reinforcing plate 120 extending to the middle of the frame, and connected in sequence.

[0056] For example, the frame is a regular hexagonal frame, and six reinforcing plates 120 are provided. One end of each of the six reinforcing plates 120 is connected to the corner of the regular hexagonal frame, and the other end of each of the six reinforcing plates 120 is connected and located at the center of the regular hexagonal frame.

[0057] By adopting the above technical solution and setting at least three reinforcing plates 120, the structural strength of the protective frame 100 is improved.

[0058] In some embodiments, the fixing component 200 includes a fixing plate 210 and a fixing member 220.

[0059] The fixing plate 210 is connected to one of the protective plate 110 and the reinforcing plate 120.

[0060] The fastener 220 is connected to the fixing plate 210 and is configured to clamp the side wall of the cylinder section 400 onto the fixing plate 210.

[0061] For example, the fixed plate 210 is an L-shaped plate, and the fastener 220 includes a cylinder and a movable plate. The cylinder is fixed on the horizontal surface of the L-shaped plate, and the movable plate is fixed on the extension end of the cylinder. The movable plate is parallel to the vertical surface of the L-shaped plate. The cylinder drives the movable plate to move back and forth, so that the movable plate moves towards or away from the fixed plate 210, thereby clamping or opening the cylinder section 400 with the fixed plate 210 and the movable plate.

[0062] By adopting the above technical solution, and by setting the fixing plate 210 and the fixing component 220, it is convenient to clamp the cylinder section 400.

[0063] In some embodiments, the fastener 220 is a bolt, and the fixing plate 210 has a threaded hole, through which the bolt is threadedly connected to the fixing plate 210.

[0064] By adopting the above technical solution, when it is necessary to fix the cylinder section 400, first place the cylinder section 400 vertically above the protective frame 100. At this time, the lower end of the cylinder section 400 abuts against the bolt. Then, tighten the bolt and move the bolt towards the fixing plate 210 until the nut in the bolt clamps the side wall of the cylinder section 400 onto the fixing plate 210, which makes it easy to fix the cylinder section 400.

[0065] In some embodiments, the fixing component 200 further includes a locking element 230.

[0066] The fixing plate 210 is slidably disposed on the reinforcing plate 120 along the length direction of the reinforcing plate 120, and the locking member 230 is configured to lock the fixing plate 210 and the reinforcing plate 120.

[0067] For example, the locking member 230 is a pin that slides through the fixing plate 210. The reinforcing plate 120 is provided with a plurality of pin holes evenly spaced along its length. When the pin is inserted into different pin holes, the relative position between the fixing plate 210 and the reinforcing plate 120 is different.

[0068] By adopting the above technical solution, by setting the locking element 230 and setting the fixing plate 210 and the reinforcing plate 120 as a sliding connection, the position of the fixing plate 210 can be adjusted, so that the fixing plate 210 can fix channels of different diameters, thereby improving the applicability of the protective device.

[0069] In some embodiments, the locking element 230 is a screw with its threads passing through the fixing plate 210 and abutting against the reinforcing plate 120.

[0070] For example, the fixing plate 210 has a through hole, and the screw is threaded into the through hole.

[0071] By adopting the above technical solution, the locking component 230 is set as a screw, and the fixing plate 210 can be fixed or opened by turning the screw, which makes it convenient for the staff to adjust the position of the fixing component 220.

[0072] In some embodiments, the fixing component 200 further includes a sliding block 240, which is connected to the fixing plate 210. The reinforcing plate 120 has a sliding groove 121, and the sliding block 240 is slidably connected to the sliding groove 121.

[0073] For example, the reinforcing plate 120 is a channel steel with the opening facing upward, so that the groove inside the channel steel is formed as a sliding groove 121.

[0074] By adopting the above technical solution and by setting the sliding block 240 and the sliding groove 121, the stability of the sliding connection between the fixed plate 210 and the reinforcing plate 120 is improved.

[0075] In some embodiments, the protective device further includes an operating platform 300, which is disposed in the middle of the protective frame 100.

[0076] For example, the operating plane is a steel plate, which is horizontally welded to the middle of the protective frame 100.

[0077] By adopting the above technical solution and setting up an operating plane, it is convenient for workers to stand on the operating platform 300 to weld the sealing platform and the cylinder section 400.

[0078] In some embodiments, the upper surface of the operating platform 300 has a pattern.

[0079] For example, the operating platform 300 is made of patterned steel, with the pattern facing away from the ground on the end face of the patterned steel.

[0080] By adopting the above technical solution, the friction of the upper surface of the operating platform 300 is increased by setting patterns on the upper surface of the operating platform 300, thereby preventing the operator from slipping when standing on the operating surface and thus avoiding certain safety hazards.
