[0040] As mentioned in the background technology: wind turbine towers are important components that support high-altitude power generation by wind turbines. Onshore wind turbine towers are generally divided into four sections. The diameter of the tower section is generally between 4 and 6 meters, and they 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 welders use auxiliary tools to weld the sealing platform to 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] In order to solve the technical problems raised above, the present application provides a wind power tower sealing platform welding protection device, which comprises a protection frame and at least three fixing components. The protection frame is placed horizontally on the ground, and the fixing components are installed on the protection frame at intervals. When the sealing platform needs to be welded to the barrel section, the barrel section is arranged vertically, and the barrel section is placed on top of the protection frame. The fixing components are then used to fix the bottom of the barrel section, and then the sealing platform is welded. At this time, the sealing platform is arranged horizontally, which is convenient for the staff to adjust the flatness of the sealing platform. The protection frame and the fixing components fix the lower end of the barrel section, thereby strengthening the structural strength of the barrel section during the welding process, thereby reducing the deformation of the barrel section during the welding process, and ensuring the performance of the barrel section after welding.

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

The protection device includes a protection frame 100 and at least three fixing components 200.

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

[0048] When welding the sealing platform to the barrel section 400, the barrel section 400 is first placed vertically (that is, the barrel section 400 is placed in the vertical direction), and then the sealing platform is placed at a suitable position of the barrel section 400, and the flatness of the sealing platform is adjusted (that is, the horizontality of the sealing platform plane is adjusted), and then the staff welds the sealing platform.

[0049] Exemplarily, six fixing assemblies 200 are provided, and the six fixing assemblies 200 are evenly spaced around the circumference, so that the six fixing assemblies 200 respectively fix the bottom of the barrel section 400, thereby ensuring the strength of the fixing assemblies 200 fixing the bottom of the barrel section 400.

[0050] Exemplarily, the fixing assembly 200 includes two clamping plates and a screw, wherein one of the clamping plates is fixed on the protective frame 100, and the other clamping plate is slidably disposed on the protective frame 100. The screw thread penetrates one of the clamping plates and is rotatably connected to the other clamping plate. By rotating the screw, the two clamping plates can be driven closer to or farther from each other, thereby achieving the fixing or opening of the bottom of the barrel section 400.

[0051] By adopting the above technical solution, when it is necessary to weld the sealing platform on the barrel section 400, the barrel section 400 is arranged vertically, and the barrel section 400 is placed above the protective frame 100. Then, the fixing assembly 200 is used to fix the bottom of the barrel section 400, and then the sealing platform is welded. At this time, the sealing platform is arranged horizontally, which is convenient for the staff to adjust the flatness of the sealing platform. In addition, the protective frame 100 and the fixing assembly 200 fix the lower end of the barrel section 400, thereby strengthening the structural strength of the barrel section 400 during the welding process, thereby reducing the deformation of the barrel section 400 during the welding process, and ensuring the performance of the barrel section 400 after welding.

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

The cylinder is fixed on the horizontal plane of the L-shaped plate, and the movable plate is fixed on the telescopic end of the cylinder. The movable plate is parallel to the vertical plane of the L-shaped plate. The movable plate is driven to move back and forth by the cylinder to move the movable plate toward or away from the fixed plate 210, thereby clamping or opening the fixed plate 210 and the movable plate on the barrel section 400.

[0064] By adopting the above technical solution, when it is necessary to fix the barrel section 400, the barrel section 400 is first placed vertically above the protective frame 100. At this time, the lower end of the barrel section 400 is in contact with the bolt, and then the bolt is screwed, and the bolt moves toward the fixing plate 210 until the nut in the bolt clamps the side wall of the barrel section 400 on the fixing plate 210, thereby facilitating the fixing of the barrel section 400.

[0065] In some embodiments, the fixing assembly 200 further includes a locking member 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 .

[0068] By adopting the above technical solution, by setting the locking member 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 application range of the protective device.

[0069] In some embodiments, the locking member 230 is a screw, and the screw thread passes through the fixing plate 210 and abuts against the reinforcing plate 120 .

[0070] Exemplarily, the fixing plate 210 has a through hole, and the screw is threadedly connected to the through hole.

[0071] By adopting the above technical solution, by setting the locking member 230 as a screw, the fixing plate 210 can be fixed or opened by screwing the screw, so that it is convenient for the staff to adjust the position of the fixing member 220.

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

[0079] Exemplarily, the operating platform 300 is made of patterned steel, and the pattern of the patterned steel is on the end surface facing away from the ground.

[0080] By adopting the above technical solution and providing a pattern on the upper surface of the operating platform 300 , the friction on the upper surface of the operating platform 300 is increased, thereby preventing workers from slipping when standing on the operating plane, thereby causing certain safety hazards.
