Description

Technical Field

[0001] This utility model relates to the field of gas-insulated metal-enclosed switchgear, and in particular to a support device for a 500kV GIS gas chamber cover. Background Technology

[0002] Gas-insulated metal-enclosed switchgear is a complete high-voltage power distribution device that encloses all primary equipment, such as circuit breakers, disconnectors, and grounding switches, in a grounded metal casing filled with SF6 gas, which has excellent insulation and arc-extinguishing properties, as the insulating and arc-extinguishing medium. The Tingzikou Company has a 500kV GIS, connected to a 500kV main transformer at the lower end and leading to the Tingzhong line at the upper end for power output. Within the 500kV GIS, the circuit breaker bay is located at the bottom of the entire GIS, supported by ground supports, and connected to the ground disconnect bay at the upper end, providing support for the ground disconnect bay and the busbar bays on both sides. When a circuit breaker is removed for any reason, the ground disconnect bay lacks vertical support, and its weight is entirely provided by the busbar bays on both sides. This causes changes in the stress on the ground disconnect bay and busbar bays, which could potentially lead to deformation, damage to the ground disconnect bays and busbars, and severely affect the gas sealing performance of the GIS, resulting in SF6 gas leakage and threatening the safe operation of the equipment.

[0003] Currently, support is provided by either hoisting with a bridge crane or welding of support components. However, bridge crane hoisting has significant drawbacks: the bridge crane has only one hanging point, so if the ground cutter bay is suspended from directly above, it is impossible to suspend another point. If the bridge crane suspends two bays simultaneously from between them, the busbar bay will still bear additional force, damaging the GIS. Welding of support components requires extremely high precision; if the height is insufficient, deformation will occur, and if it is too high, it will be difficult to fit the support component into the gap below the ground cutter bay. Furthermore, the height is fixed after welding, which cannot provide support for other GIS components and results in poor compatibility.

[0004] Therefore, it is necessary to provide a support device for the 500kV GIS gas chamber cover to solve the above-mentioned technical problems. Summary of the Invention

[0005] This utility model provides a support device for the 500kV GIS gas chamber cover, which solves the problem that the current method of supporting the GIS by hoisting with a bridge crane or welding support components causes the busbar bay to bear additional forces, resulting in damage to the GIS.

[0006] To solve the above-mentioned technical problems, this utility model provides a support device for a 500kV GIS gas chamber cover, comprising: a support base, an adjustment device, and a support frame; The adjustment device includes a support rod, a threaded sleeve, multiple movable rods, an adjusting rod, multiple limiting holes, a limiting rod, and a moving groove. One end of the support rod is fixedly connected to the top of the support base. The threaded sleeve is threadedly connected to the surface of the support rod. One end of each of the multiple movable rods is fixedly connected to the surface of the threaded sleeve. The adjusting rod is slidably connected to the inside of the support rod. The multiple limiting holes are all opened inside the adjusting rod. The limiting rod is slidably connected to the inside of the limiting holes. The moving groove is opened inside the support rod. The bottom of the support frame is fixedly connected to one end of the adjusting rod.

[0007] Preferably, two mounting brackets are fixedly connected to the surface of the support base, and a moving device is fixedly installed on one side of each of the two mounting brackets.

[0008] Preferably, the support frame is a Y-shaped frame, which provides symmetrical support to the two force-bearing points on both sides of the bottom of the ground-level blade spacer.

[0009] Preferably, the top of the threaded sleeve is rotatably connected to a rotating sleeve, and the top of the rotating sleeve is fixedly connected to two limiting rings.

[0010] Preferably, the rotating sleeve is provided with a reset device, which includes two reset slots, two reset blocks and two reset components. The two reset slots are opened inside the rotating sleeve, the two reset blocks are slidably connected to the interior of the two reset slots, and the two reset components are respectively disposed inside the interior of the two reset slots.

[0011] Preferably, the two reset elements are springs, which are disposed inside the reset groove and located at the bottom of the reset block.

The support frame adopts a Y-shaped structure, which can simultaneously fit the two stress points on both sides of the bottom of the ground separator, forming symmetrical support and avoiding single-point stress concentration. At the same time, the height of the support frame can be adjusted by the adjustment device, so as to accurately match the gap height between the bottom of the ground separator and the ground, avoiding deformation caused by insufficient height, and eliminating the problem of not being able to insert it due to excessive height.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] First Embodiment

[0018] Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a support device for a 500kV GIS air chamber cover provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the adjusting device. A support device for a 500kV GIS gas chamber cover includes: a support base 1, an adjusting device 2, and a support frame 3; The adjusting device 2 includes a support rod 21, a threaded sleeve 22, multiple moving rods 23, an adjusting rod 24, multiple limiting holes 25, a limiting rod 26, and a moving groove 27. One end of the support rod 21 is fixedly connected to the top of the support base 1. The threaded sleeve 22 is threadedly connected to the surface of the support rod 21. One end of each of the multiple moving rods 23 is fixedly connected to the surface of the threaded sleeve 22. The adjusting rod 24 is slidably connected to the inside of the support rod 21. The multiple limiting holes 25 are all opened inside the adjusting rod 24. The limiting rod 26 is slidably connected to the inside of the limiting holes 25. The moving groove 27 is opened inside the support rod 21. The bottom of the support frame 3 is fixedly connected to one end of the adjusting rod 24.

[0019] The movable groove 27 is formed inside the support rod 21 and extends through the support rod 21. It is used to allow the limiting rod 26 to be inserted through the support rod 21 after the limiting rod 26 is inserted into the limiting hole 25. By rotating the threaded sleeve 22, the threaded sleeve 22 pushes the limiting rod 26 to move inside the movable groove 27, thereby driving the adjusting rod 24 to move upward and finely adjust the position of the support frame 3.

[0020] The surface of the support rod 21 is provided with threads that are compatible with the threaded sleeve 22.

[0021] Two mounting brackets 4 are fixedly connected to the surface of the support base 1, and a moving device 5 is fixedly installed on one side of each of the two mounting brackets 4.

[0022] The mobile device 5 is a caster wheel, which is used to facilitate the movement of the support base 1. When the support device is unloaded, it can flexibly move through the narrow space of the GIS. Compared with the bulky bridge crane, the space adaptability is greatly improved, and manpower and material resources are also saved.

[0023] The support frame 3 is a Y-shaped frame, which provides symmetrical support to the two sides of the bottom of the ground-level blade spacer.

[0024] The working principle of the support device for the 500kV GIS gas chamber cover provided by this utility model is as follows: In use, by moving the adjusting rod 24 upward, the inside of the support rod 21 is moved upward, so that the support frame 3 is moved to the appropriate position. Then, the limiting rod 26 is inserted into the limiting hole 25 to limit the adjusting rod 24.

[0025] When multiple moving rods 23 are rotated to one side, the threaded sleeve 22 is rotated to one side, causing the threaded sleeve 22 to move upward on the surface of the support rod 21. This pushes the limiting rod 26 to move the adjusting rod 24 upward. At the same time, the limiting rod 26 moves inside the moving groove 27, thereby fine-tuning the position of the adjusting rod 24 by rotating the threaded sleeve 22.

[0026] Compared with related technologies, the support device for a 500kV GIS gas chamber cover provided by this utility model has the following advantages: This utility model provides a support device for a 500kV GIS gas chamber cap. The support frame 3 adopts a Y-shaped structure, which can simultaneously fit the two stress points on both sides of the bottom of the ground blade spacer to form symmetrical support, avoiding single-point stress concentration. At the same time, the height of the support frame 3 can be adjusted by the adjustment device 2, so as to accurately match the gap height between the bottom of the ground blade spacer and the ground, avoiding deformation caused by insufficient height, and eliminating the problem of not being able to insert it due to excessive height.

[0027] Second Embodiment

[0028] Please refer to the following: Figure 3 , Figure 4 and Figure 5 Based on the first embodiment of this application, which provides a support device for a 500kV GIS air chamber cover, the second embodiment of this application proposes another support device for a 500kV GIS air chamber cover. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0029] Specifically, the second embodiment of this application provides a support device for a 500kV GIS gas chamber cover, which differs in that it also includes a rotating sleeve 10. One end of the rotating sleeve 10 is rotatably connected to the top of the threaded sleeve 22, and two limiting rings 9 are fixedly connected to the top of the rotating sleeve 10.

[0030] Two limiting rings 9 are used to limit the movement between the limiting rod 26 and the rotating sleeve 10.

[0031] The rotating sleeve 10 is provided with a reset device 6 inside. The reset device 6 includes two reset slots 61, two reset blocks 62 and two reset elements 63. The two reset slots 61 are opened inside the rotating sleeve 10. The two reset blocks 62 are slidably connected to the inside of the two reset slots 61 respectively. The two reset elements 63 are respectively disposed inside the two reset slots 61.

[0032] The reset element 63 is a spring piece, which is located inside the reset groove 61 and at the bottom of the reset block 62, and is used to push the reset block 62 to move upward.

[0033] The two reset members 63 are springs, which are disposed inside the reset groove 61 and located at the bottom of the reset block 62.

[0034] The spring is used to push the reset block 62 to reset, thereby causing the fixed block 7 to move upward.

[0035] Each of the two reset blocks 62 is fixedly connected to a fixing block 7 on one side, and each of the two fixing blocks 7 has a guide groove 8 inside.

[0036] The guide groove 8 is used to automatically move downward along the inclined surface after the limiting rod 26 is inserted into the inside of the guide groove 8, thereby facilitating the installation of the limiting rod 26.

[0037] Two fixing blocks 7 are used to limit the two ends of the limiting rod 26, thereby increasing the limiting effect of the limiting ring 9.

[0038] The working principle of the support device for the 500kV GIS gas chamber cover provided by this utility model is as follows: In use, by moving the fixed block 7 downward, the reset block 62 moves inside the reset groove 61, while simultaneously squeezing the reset member 63. When the fixed block 7 moves downward to the appropriate position, the limiting rod 26 is inserted into the limiting ring 9. The reset member 63 then pushes the reset block 62 to move upward inside the reset groove 61, thereby moving the fixed block 7 upward. At the same time, the fixed block 7 is inserted into the limiting hole 25 inside the adjusting rod 24, thus limiting the limit rod 26 and the inside of the rotating sleeve 10.

[0039] Compared with related technologies, the support device for a 500kV GIS gas chamber cover provided by this utility model has the following advantages: This utility model provides a support device for the 500kV GIS gas chamber cover. The rotating sleeve 10, in conjunction with the reset device 6, the fixing block 7 and the limiting ring 9, limits the movement between the threaded sleeve 22 and the limiting rod 26, thereby increasing the stability of the limiting rod 26 when it is in the limiting position.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
