Description

Technical Field

[0001] This utility model relates to the technical field of protective structures for welding equipment, and more specifically, to a protective cover for welding wind power busbars. Background Technology

[0002] During the welding process of wind turbine busbars, welding spatter easily adheres to the surface of the busbar conduit, affecting not only its appearance but also potentially causing defects such as pits and cracks, thus reducing its electrical performance and mechanical strength. Simultaneously, the welding area, exposed to high temperatures and air, is highly susceptible to oxidation, leading to a decline in the performance of the weld joint and the formation of welding defects such as porosity and slag inclusions. These factors severely impact the welding quality and service life of the wind turbine busbars.

[0003] Currently, most existing welding protection measures use fixed protective covers, which cannot be opened and closed automatically. During welding operations, they require frequent manual disassembly and installation, which is inconvenient, inefficient, and makes it difficult to accurately protect the welding area in real time. In view of this, we propose a welding protective cover for wind power busbars. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a wind power bus welding protective cover to solve the technical problems of the current fixed protective cover requiring frequent manual disassembly and installation, which is inconvenient to operate and has low work efficiency.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a wind power bus welding protective cover, including a base, two arc-shaped protective covers are movably installed inside the base, an adjustment component for squeezing the displacement of the protective cover is installed through the top of the base, and several connecting rod components for pulling the protective cover back to its original position are fixedly arranged on the opposite sides of the two protective covers.

[0006] An adjustment cavity adapted to the protective cover is provided between the two ends of the top of the base, and a limiting part for limiting the position of the busbar is constructed on the top of the base.

[0007] The adjustment assembly includes two through adjustment plates, and an arc-shaped pressure plate is fixedly disposed between the tops of the two adjustment plates.

[0008] This invention features a movable arc-shaped protective cover inside the base. Combined with an adjustment component at the top, the adjustment component can be automatically pressed down by placing the busbar pipe, pushing the protective cover inside the base outward. This provides precise protection for the welded parts of the wind power busbar. Furthermore, the protective cover can be automatically reset when the busbar pipe is removed by pulling the connecting rod assembly, achieving automatic adjustment of the protective cover's position. This solves the problem of frequent disassembly and assembly and improves operational efficiency.

[0009] Preferably, the adjusting plate includes a squeezing part located inside the adjusting cavity, the top of the squeezing part is integrally formed with a resilient pressing part, and the plate wall of the pressing part is vertically constructed with a plurality of elastic grooves.

[0010] Preferably, a plurality of support bars for limiting are vertically slidably installed between two adjacent pressing parts, and the shape of the support bars is the same as that of the arc-shaped pressure plate.

[0011] Preferably, each of the two adjacent pressing parts has a vertically formed groove on its facing surface, and each end of the support bar has a slider that is movably connected to the groove.

[0012] Preferably, the linkage assembly includes a rotating seat fixed to the surface of the protective cover, a connecting rod rotatably mounted between the inner walls of the rotating seat, a rotary joint rotatably mounted at the other end of the connecting rod, and a second connecting rod for limiting the position retractably mounted at the end of the rotary joint.

[0013] Preferably, a connecting rod is movably installed inside the second connecting rod and fixedly connected to the end of the rotary joint. A limiting circular plate that fits against the inner wall of the second connecting rod is fixedly provided on the side end of the connecting rod inside the second connecting rod. A spring sleeved on the outside of the connecting rod is fixedly connected between the limiting circular plate and the facing surface inside the second connecting rod.

[0014] Preferably, a plurality of flexible support blocks are fixedly provided on the side wall of the limiting part, and the internal structure of the support blocks has an elastic cavity.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model features a movable arc-shaped protective cover inside the base. Combined with the top adjustment component, the busbar tube can be placed to automatically press the adjustment component downward, pushing the protective cover inside the base outward. This achieves precise protection of the welded parts of the wind power busbar. With the pull of the connecting rod component, the protective cover can be automatically reset when the busbar tube is removed, achieving the effect of automatically adjusting the position of the protective cover. This solves the problem of frequent disassembly and assembly and improves operational efficiency.

[0017] 2. This utility model further improves bending toughness by constructing several elastic grooves on the resilient pressing part, so that it can automatically deform and bend to push the pressing part position when entering the adjustment cavity. The arc-shaped support bar design can strengthen the vertical compressive strength of the two adjustment plates. Combined with the arc-shaped pressure plate design, it is not easy to bend during the pressing of the busbar pipe, thereby further improving the structural fit effect and maintaining the smooth opening and closing of the protective cover.

[0024] like Figures 1 to 5 As shown, this utility model relates to a wind power busbar welding protective cover, which includes a base 1. Two arc-shaped protective covers 2 are movably installed inside the base 1. An adjustment component 3 for squeezing the protective cover 2 is installed through the top of the base 1. Several connecting rod components 4 for pulling the protective cover 2 back to its original position are fixedly arranged on the opposite sides of the two protective covers 2. By squeezing the two protective covers 2 inside the base 1, the two protective covers 2 can be displaced along the arc angle. When the two are in close contact, the busbar pipe can be wrapped inside, achieving the effect of welding protection.

[0025] An adjustment cavity 101 adapted to the protective cover 2 is provided between the two ends of the top of the base 1. The top of the base 1 is constructed with a limiting part 102 for limiting the position of the busbar pipe. The adjustment assembly 3 includes two through adjustment plates 5. An arc-shaped pressure plate 6 is fixedly provided between the tops of the two adjustment plates 5. The opening of the adjustment cavity 101 can limit the angle of displacement of the protective cover 2. The setting of the arc-shaped pressure plate 6 can make the pressure on the two adjustment plates 5 uniform, so as to achieve the effect of synchronous downward movement.

[0026] In an embodiment of this utility model, the adjusting plate 5 includes a pressing part 501 located inside the adjusting cavity 101. The top of the pressing part 501 is integrally formed with a resilient pressing part 502. The pressing part 502 has a plurality of elastic grooves 503 vertically constructed on its plate wall. The shape of the pressing part 501 inside the adjusting cavity 101 is the same as that of the adjusting cavity 101, and the corners are rounded. The resilient pressing part 502 can automatically deform when it moves down into the adjusting cavity 101. Its material can be a metal material with good toughness, which has a good rebound and recovery effect. The opening of the elastic grooves 503 can enhance the flexibility and facilitate the displacement of the pressing part 501 after it enters the adjusting cavity 101.

[0027] In an embodiment of this utility model, a plurality of support bars 7 for limiting are vertically slidably installed between two adjacent pressing parts 502, and the shape of the support bars 7 is the same as the shape of the arc-shaped pressure plate 6; the setting of the support bars 7 can increase the connection strength between the two adjusting plates 5, so that the pressing part 502 is not easy to bend when pressed by the busbar pipe, thereby improving the compressive strength.

[0028] In the embodiments of this utility model, the opposing surfaces of two adjacent pressing parts 502 are vertically provided with sliding grooves 504, and both ends of the support bar 7 are fixedly provided with sliders 701 that are movably connected to the sliding grooves 504; through the cooperation of the sliding grooves 504 and the sliders 701, the support bar 7 can be automatically squeezed to move upward during the downward movement of the pressing part 502, so as not to affect the downward movement of the pressing part 502. The cross-sections of the sliding grooves 504 and the sliders 701 are both T-shaped, which have a good limiting effect while being slidable.

[0029] In an embodiment of this utility model, the connecting rod assembly 4 includes a rotating seat 401 fixed to the surface of the protective cover 2. A connecting rod 402 is rotatably mounted between the inner walls of the rotating seat 401. A rotary joint 403 is rotatably mounted at the other end of the connecting rod 402. A second connecting rod 404 for limiting is telescopically mounted at the end of the rotary joint 403. The position angle of the connecting rod 402 can be automatically adjusted when the protective cover 2 is displaced by the setting of the rotating seat 401 and the rotary joint 403, and the effect of automatic reset can be achieved by the pulling of the second connecting rod 404.

[0030] In an embodiment of this utility model, a connecting rod 405 is movably installed inside the second connecting rod 404 and fixedly connected to the end of the rotary joint 403. A limiting circular plate 406 is fixedly provided on the side end of the connecting rod 405 inside the second connecting rod 404, which is in contact with the inner wall of the second connecting rod 404. A spring 407 sleeved on the outside of the connecting rod 405 is fixedly connected between the limiting circular plate 406 and the facing surface inside the second connecting rod 404. By setting the limiting circular plate 406, the spring 407 can be squeezed to contract when the connecting rod 405 is displaced, forming an elastic force. In this way, when the protective cover 2 loses pressure, it can automatically reset through the rebound force of the spring 407, thereby achieving the effect of automatic opening and closing.

[0031] In an embodiment of this utility model, a plurality of flexible support blocks 103 are fixedly provided on the side wall of the limiting part 102, and the internal structure of the support block 103 has an elastic cavity; the design of the support block 103 can improve the fit with the busbar pipe and improve the stability of the position.

[0032] Working Principle: This embodiment provides a wind power busbar welding protective cover. When placing the wind power busbar, the busbar is first placed in the limiting part 102 at the top of the base 1. This allows the bottom of the busbar to fit against the top of the arc-shaped pressure plate 6. Its own weight can press the two bottom adjusting plates 5 into the adjusting cavity 101, causing the resilient pressing part 502 to deform within the adjusting cavity 101. This pushes the squeezing part 501 upwards along the arc, thereby pushing the two internal protective covers 2 closer together along the arc, achieving the effect of protecting the busbar. During the movement of the protective cover 2, the length of the connecting rod assembly 4 can be changed. The cooperation between the rotating seat 401 and the rotating joint 403 can change the angle of the connecting rod 402, simultaneously pulling the connecting rod 405 outwards. This causes the limiting circular plate 406 to compress the spring 407, thus applying a pulling force to the protective cover 2. When the busbar... After placement, it can contact the flexible support block 103 on the side wall of the limiting part 102. Under the action of the elastic cavity inside the support block 103, it can be squeezed and deformed by the busbar tube, thereby maintaining a good fit and keeping it stable during the welding process, preventing shaking or displacement. When the welding work is completed, the busbar tube can be moved to release the pressure of the adjusting plate 5. At the same time, the protective cover 2 also loses the squeezing of the squeezing part 501, causing the connecting rod 405 to move back under the force of the spring 407, pulling the connecting rod 402 to reset. This can drive the protective covers 2 on both sides to move back, achieving the effect of releasing the protection and making it easy to remove the busbar tube. Through the cooperation of the overall structure, the effects of automatic protection and release of protection can be achieved, effectively reducing the amount of manual work and improving work efficiency.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
