[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 10As shown, the present invention provides a high-voltage electrical equipment maintenance workbench for power design, including a workbench body 1, a leak-proof mechanism 2 installed on the outside of the workbench body 1, a testing frame 3 fixed to the top of the workbench body 1, a testing port 4 fixed to the outside of the testing frame 3, a cleaning mechanism 5 installed on the outside of the testing frame 3, a limiting mechanism 6 fixed inside the workbench body 1, a first storage box 7 slidably connected inside the workbench body 1, a second storage box 8 installed inside the workbench body 1, several groups of testing ports 4 arranged in an array, the outer wall of the first storage box 7 fitting against the inner wall of the workbench body 1, the first storage box 7 and the workbench body 1 being slidably connected, and the second storage box 8 and the workbench body 1 being slidably connected.

[0021] The above solution involves placing the high-voltage electrical equipment on the top of the workbench body 1, connecting the wiring of the high-voltage electrical equipment to the inside of the detection port 4, and then testing the high-voltage electrical equipment. The first storage box 7 and the second storage box 8 can store the testing tools.

[0022] like Figures 1 to 4 As shown, the leak-proof mechanism 2 includes an extension frame 201, a first lever 202, and a first bevel gear 203. The extension frame 201 is fixed to the outside of the workbench body 1. The first lever 202 is rotatably connected inside the extension frame 201. The first bevel gear 203 is fixed to the outside of the first lever 202. The second bevel gear 204 is rotatably connected inside the extension frame 201. The first baffle 205 is fixed to the outside of the second bevel gear 204. The third bevel gear 206 is rotatably connected inside the extension frame 201. A second baffle 207 is fixed to the outside of 06. The first bevel gear 203 and the second bevel gear 204 are meshed and connected. The second bevel gear 204 and the first baffle 205 are meshed and connected. There are two sets of the second bevel gear 204 and the first baffle 205. The second bevel gear 204 and the first baffle 205 are symmetrically distributed about the central axis of the worktable body 1. There are two sets of the third bevel gear 206 and the second baffle 207. The third bevel gear 206 and the second baffle 207 are symmetrically distributed about the central axis of the worktable body 1.

[0023] The above scheme is adopted as follows: by rotating the first lever 202, the first bevel gear 203 is rotated, which drives the second bevel gear 204 to rotate, and then the second bevel gear 204 drives the third bevel gear 206 to rotate, so that the first baffle 205 rotates with the second bevel gear 204, and the second baffle 207 drives the third bevel gear 206 to rotate, thereby rotating the first baffle 205 and the second baffle 207.

[0024] like Figures 1 to 8As shown, the cleaning mechanism 5 includes a first servo motor 501, a reciprocating screw 502, and a cleaning frame 503. The first servo motor 501 is fixed to the outside of the detection frame 3. The reciprocating screw 502 is fixed to the drive end of the first servo motor 501. The cleaning frame 503 is installed on the outside of the reciprocating screw 502. Cleaning bristles 504 are fixed to the outside of the cleaning frame 503. A return spring 505 is fixed to the top of the inside of the cleaning frame 503. A ball bearing 506 is fixed to the bottom of the return spring 505. There are two sets of return springs 505 and ball bearings 506. The return springs 505 and ball bearings 506 are symmetrically distributed about the central axis of the cleaning frame 503. The return springs 505 are used to squeeze the ball bearings 506 and keep them moving downwards.

[0025] like Figures 1 to 8 As shown, the top of the detection frame 3 is provided with a vibration groove 507, the cleaning frame 503 is fixed with a positioning rod 508, the positioning rod 508 is fixed with an electric motor 509, the drive end of the electric motor 509 is fixed with a movable screw 510, the movable screw 510 is threadedly connected to an infrared positioning box 511, the vibration groove 507 is provided with several sets, the vibration groove 507 is arranged at equal intervals, the inner diameter of the vibration groove 507 is larger than the outer diameter of the ball 506, and the outer diameter of the positioning rod 508 is equal to the height of the cleaning frame 503.

[0026] The above scheme is adopted as follows: After the device is used to test the high-voltage electrical equipment, when the device is idle, the first servo motor 501 is started to drive the reciprocating screw 502 to rotate. The rotation of the reciprocating screw 502 drives the cleaning frame 503 to reciprocate on the reciprocating screw 502, thereby cleaning the surface of the detection port 4 through the cleaning bristles 504. When the cleaning frame 503 moves, it drives the return spring 505 and the ball 506 to reciprocate. After the ball 506 moves to the top of the vibration groove 507, the restoring force of the return spring 505 squeezes the ball 506 into the interior of the vibration groove 507, thereby generating vibration. This makes the cleaning bristles 504 improve the cleaning efficiency of the detection port 4 through vibration. During cleaning, the electric motor 509 can be started to drive the movable screw 510 to rotate, and the threads on the outside of the movable screw 510 drive the infrared positioning box 511 to move.

[0027] like Figures 1 to 10As shown, the limiting mechanism 6 includes a support plate 601, a second servo motor 602, and a first gear 603. The support plate 601 is fixed to the bottom end of the worktable body 1. The second servo motor 602 is fixed to the bottom end of the support plate 601. The first gear 603 is fixed to the drive end of the second servo motor 602. The first gear 603 is externally meshed with a first rack 604. The first rack 604 is externally fixed with a second rack 605. There are two sets of first racks 604. The first racks 604 are symmetrically distributed about the central axis of the first gear 603. The outer wall of the second rack 605 is attached to the inner wall of the worktable body 1. The second rack 605 and the worktable body 1 are slidably connected.

[0028] like Figures 1 to 10 As shown, a support rod 606 is rotatably connected inside the main body 1 of the workbench. A second gear 607 is fixed to the outside of the support rod 606, and a limit rod 608 is fixed to the outside of the support rod 606. There are two sets of support rod 606, second gear 607 and limit rod 608. The support rod 606, second gear 607 and limit rod 608 are symmetrically distributed about the central axis of the support plate 601. Several sets of teeth are fixed to the outside of the second rack 605, and several sets of teeth are fixed to the outside of the second gear 607. The second rack 605 and the second gear 607 are meshed together.

[0029] The above scheme is adopted: after the high-voltage electrical equipment is placed, the second servo motor 602 is started to drive the first gear 603 to rotate, and then the first gear 603 drives the two sets of first racks 604 and second racks 605 to move in opposite directions, and then the second racks 605 drive the two sets of support rods 606, second gears 607 and limit rods 608 to rotate.

[0030] The working principle and usage process of this invention are as follows: After placing the high-voltage electrical equipment on the top of the workbench body 1, the wiring of the high-voltage electrical equipment is connected to the inside of the detection port 4 to test the high-voltage electrical equipment. The first storage box 7 and the second storage box 8 can store the testing tools.

[0031] First, by rotating the first lever 202, the first bevel gear 203 is rotated, causing the first bevel gear 203 to drive the second bevel gear 204 to rotate. Then, the second bevel gear 204 drives the third bevel gear 206 to rotate, causing the first baffle 205 to rotate with the second bevel gear 204. The second baffle 207 drives the third bevel gear 206 to rotate, thereby rotating the first baffle 205 and the second baffle 207. This allows the first baffle 205 and the second baffle 207 to block the top of the workbench body 1 after the high-voltage electrical equipment is placed, thus preventing parts from falling.

[0032] Secondly, after the high-voltage electrical equipment is placed, the second servo motor 602 is started to drive the first gear 603 to rotate. Then, the first gear 603 drives the two sets of first racks 604 and second racks 605 to move in opposite directions. Then, the second racks 605 drive the two sets of support rods 606, the second gear 607 and the limit rods 608 to rotate. Finally, the four sets of limit rods 608 limit the high-voltage electrical equipment, thereby preventing the position of the high-voltage electrical equipment from shifting during the detection process.

[0033] Finally, after the high-voltage electrical equipment is tested using the device, when the device is idle, the first servo motor 501 is started to drive the reciprocating screw 502 to rotate. The rotation of the reciprocating screw 502 drives the cleaning frame 503 to reciprocate on the reciprocating screw 502, thereby cleaning the surface of the detection port 4 with the cleaning bristles 504. When the cleaning frame 503 moves, it drives the return spring 505 and the ball 506 to reciprocate. After the ball 506 moves to the top of the vibration groove 507, the restoring force of the return spring 505 squeezes the ball 506 into the interior of the vibration groove 507, thereby generating vibration. This makes the cleaning bristles 504 improve the cleaning efficiency of the detection port 4 by vibration. During cleaning, the electric motor 509 can be started to drive the movable screw 510 to rotate. The threads on the outside of the movable screw 510 drive the infrared positioning box 511 to move, thereby locating the position of the high-voltage electrical equipment by the laser red dot emitted by the infrared positioning box 511.

[0034] The main body of the workbench 1 is a horizontal load-bearing structure with a smooth top surface to ensure that the high-voltage electrical equipment is placed stably. The first storage box 7 and the second storage box 8 are symmetrically distributed inside the main body of the workbench 1, and the inner wall is adapted to the contour of the tool to achieve classified storage. The detection ports 4 are distributed in an array on the outside of the detection frame 3, and the wiring ports are matched with the wiring specifications of the high-voltage electrical equipment to ensure stable connection. The extension frame 201 is fixed on both sides of the main body of the workbench 1 to provide rotational support for the bevel gears. The first bevel gear 203 meshes with the second bevel gear 204, and the second bevel gear 204 meshes with the third bevel gear 206. The transmission ratio is precise to ensure that the first baffle 205 and the second baffle 207 rotate and unfold synchronously to surround the top edge of the main body of the workbench 1 to form a protective barrier.

[0035] The first servo motor 501 is fixed to the outside of the detection frame 3. The reciprocating screw 502 rotates and drives the cleaning frame 503 to move linearly back and forth. The cleaning bristles 504 are attached to the surface of the detection port 4. The reset spring 505 continuously squeezes the ball 506. The ball 506 is embedded in the vibration groove 507 to generate high-frequency vibration, which enhances the impurity removal effect. The electric motor 509 drives the movable screw 510 to rotate, which drives the infrared positioning box 511 to move. The laser red dot accurately marks the reference position of the equipment placement, ensuring that the equipment position is consistent during each test.
