Description

Technical Field

[0001] This utility model relates to the field of high-voltage bushing technology, and in particular to a pluggable, quick-installation high-voltage bushing. Background Technology

[0002] High-voltage bushings are devices that allow one or more conductors to pass through partitions such as walls or enclosures, serving as insulation and support. They are important equipment in power systems. High-voltage bushings are mainly used for ground insulation of incoming and outgoing lines of power equipment such as transformers, reactors, and circuit breakers, as well as for high-voltage circuits passing through walls.

[0003] The existing high-pressure bushings are installed by passing them through pre-drilled holes in the wall and fixing them with bolts. This method is cumbersome to disassemble and replace because of the bolt connection. It does not allow for direct pulling out and inserting of the high-pressure bushing, which affects the efficiency of disassembly and assembly and results in poor performance. Therefore, there is an urgent need for a pluggable and quick-installation high-pressure bushing to solve the above problems. Utility Model Content

[0004] The main purpose of this invention is to provide a pluggable, quick-installation high-pressure bushing.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A pluggable, quick-installation high-pressure bushing includes a bushing body. Four sets of clamping assemblies are circumferentially distributed on the outer wall of the bushing body. Each clamping assembly consists of a support, a bidirectional screw, a guide rod, a screw block, and a self-folding support rod. A driving assembly is fixed to the top of each clamping assembly. The driving assembly consists of a ring-shaped driving seat, a gear ring, a limiting ring, a gear, a lever, a connecting frame, a telescopic positioning rod, a lifting block, and positioning holes arranged in a circumferential array.

[0007] Preferably, the support is welded to the outer wall of the sleeve body, the bidirectional screw is rotatably installed between the supports, and the guide rod is welded between the supports.

[0008] Preferably, the screw block is threaded onto the bidirectional screw rod, the guide rod passes through the screw block, and both ends of the support rod are hinged to the screw block.

[0009] Preferably, the drive seat is welded to the outer wall of the sleeve body, the gear ring is rotatably mounted on the drive seat through the limiting ring, and the lever is fixed to one side wall of the gear ring.

[0010] Preferably, the gear ring meshes with the gear, and the gear is fixedly connected to the top end of the bidirectional screw.

[0011] Preferably, the connecting frame is rotatably mounted on the lever block, the positioning rod is welded to one end of the connecting frame, and the lifting block is welded to the movable arm of the positioning rod.

[0012] Preferably, the positioning hole is formed on the drive seat, and the specifications of the positioning hole match the specifications of the movable arm of the positioning rod.

[0013] The beneficial technical effects of this utility model are as follows:

[0014] This utility model, through the design of a drive component and a clamping component, allows the gear ring to rotate via a paddle block within the drive component during installation. This gear ring then drives four sets of gears to rotate synchronously. These four sets of gears, in turn, drive four sets of bidirectional screws within the clamping components to rotate synchronously. This causes the screw block to move under the action of the thread and guide rod. During this movement, the support rod rotates and clamps itself against a pre-drilled hole in the wall through its folded section, thus enabling the installation of the bushing. For disassembly, simply reverse the gear ring, allowing for quick insertion and removal of the bushing and effectively improving the performance of the high-pressure bushing.

[0021] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0022] like Figures 1-4 As shown, this embodiment provides a pluggable quick-installation high-pressure bushing, including a bushing body 1. Four sets of clamping components 3 are circumferentially distributed on the outer wall of the bushing body 1. Each clamping component 3 consists of a support 301, a bidirectional screw 302, a guide rod 305, a screw block 303, and a self-folding support rod 304. A driving component 2 is fixed to the top of the clamping component 3. The driving component 2 consists of a ring-shaped driving seat 201, a gear ring 202, a limiting ring 209, a gear 208, a lever block 204, a connecting frame 205, a telescopic positioning rod 206, a lifting block 207, and positioning holes 203 arranged in a circumferential array.

[0023] Support 301 is welded to the outer wall of the sleeve body 1. Bidirectional screw 302 is rotatably installed between supports 301. Guide rod 305 is welded between supports 301. Guide rod 305 limits and guides the movement of screw block 303.

[0024] The screw block 303 is screwed onto the bidirectional screw rod 302 by a thread. The guide rod 305 passes through the screw block 303. Both ends of the support rod 304 are hinged to the screw block 303. During the rotation of the bidirectional screw rod 302, the screw block 303 moves under the action of the thread and the guide rod 305. During the movement, the support rod 304 rotates and then presses against the through hole reserved in the wall through the fold of the support rod 304.

[0025] The drive seat 201 is welded to the outer wall of the sleeve body 1. The gear ring 202 is rotatably mounted on the drive seat 201 through the limiting ring 209. The lever 204 is fixed on one side wall of the gear ring 202. The lever 204 can drive the gear ring 202 to rotate.

[0026] The gear ring 202 meshes with the gear 208, and the gear 208 is fixedly connected to the top of the double-acting screw 302. The gear ring 202 drives the double-acting screw 302 to rotate through the gear 208.

[0027] The connecting frame 205 is rotatably mounted on the lever 204. The positioning rod 206 is welded to one end of the connecting frame 205. The lifting block 207 is welded to the movable arm of the positioning rod 206. The lifting block 207 can facilitate the separation of the positioning rod 206 from the positioning hole 203, thereby releasing the fixation of the gear ring 202.

[0028] The positioning hole 203 is formed on the drive seat 201. The specifications of the positioning hole 203 match the specifications of the movable arm of the positioning rod 206. After installation, the positioning rod 206 is rotated above the corresponding positioning hole 203 through the connecting bracket 205, and then inserted into the positioning hole 203 to fix the gear ring 202.

[0029] The working principle of this device is as follows: During installation, the sleeve body 1 is inserted into the pre-drilled through hole in the wall. Then, the lever 204 drives the gear ring 202 to rotate, which in turn drives the four sets of gears 208 to rotate synchronously. The four sets of gears 208 then drive the four sets of bidirectional screws 302 in the clamping components 3 to rotate synchronously. This causes the screw block 303 to move under the action of the thread and the guide rod 305. During the movement, the support rod 304 rotates, and then the support rod 304 folds... The sleeve is tightened with the pre-drilled hole in the wall to allow for installation. Then, the positioning rod 206 is rotated above the corresponding positioning hole 203 via the connecting bracket 205 and inserted into the positioning hole 203 to fix the gear ring 202. During disassembly, the positioning rod 206 is separated from the positioning hole 203 by the lifting block 207, thereby releasing the fixation of the gear ring 202. Then, the gear ring 202 can be reversed to achieve quick insertion and removal of the sleeve, effectively improving the performance of the high-pressure sleeve.

[0030] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
