Description

Technical Field

[0001] This invention relates to the field of switchgear technology, specifically to an adjustable high and low voltage switchgear. Background Technology

[0002] The carving and grinding device for the inner wall of precious wood cups is mainly used for fine carving and grinding of the inner wall of precious wood cups, in order to preserve the natural texture of the wood while enhancing its aesthetic appeal and usability. This type of device typically combines carving and grinding techniques and is characterized by high precision and complexity.

[0003] Chinese patent CN118589333B, authorized and published on January 10, 2025, discloses an integrated installation structure and a high and low voltage switchgear, which includes a truck compartment, a circuit breaker is installed in the truck compartment, and a fast-moving mechanism for moving the circuit breaker is provided in the truck compartment.

[0004] In the aforementioned application documents, a quick-moving mechanism is used to move the circuit breaker accordingly. In existing devices, in order to facilitate the maintenance of the circuit breaker, it is often pulled out manually. After the maintenance operation is completed, the circuit breaker is manually pushed back to reset it. At this time, if the circuit breaker is accidentally pushed quickly, the moving contact on the circuit breaker will collide rapidly with the stationary contact inside the switch cabinet, which may cause damage. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable high- and low-voltage switchgear, solving the problems mentioned in the background section. To achieve the above objectives, this invention provides the following technical solution: an adjustable high- and low-voltage switchgear, comprising: The main body of the switch cabinet is equipped with a fixed slide rail inside, and the top of the fixed slide rail is slidably connected to the circuit breaker body; The moving contact is mounted on the side of the circuit breaker body, and the stationary contact is mounted inside the switch cabinet body; A rotating rod is mounted on the side of the circuit breaker body, and a torsion spring rod is rotatably connected inside the switch cabinet body. A transmission component for transmission is mounted between the rotating rod and the torsion spring rod. A transmission rod two is fixedly connected to the bottom of the torsion spring rod, and a friction block is hinged to the side of the transmission rod two. An auxiliary limiting component for limiting the circuit breaker body is mounted on the top of the fixed slide rail, and an auxiliary adsorption component for limiting the circuit breaker body is mounted on the side of the friction block.

[0006] Preferably, the transmission component includes a hydraulic chamber mounted on the outside of the rotating rod. Inside the hydraulic chamber, a movable block is slidably connected via a piston. An elastic telescopic rod is mounted on the side of the movable block. A compression arc rod is slidably connected to the side of the hydraulic chamber via a piston. A transmission rod is fixedly connected to the top of the torsion spring rod, and a force-bearing block is hinged to the side of the transmission rod. This device design ensures that when the circuit breaker body is accidentally pushed in or pulled out quickly, the friction block moves out of the fixed slide rail and contacts the side of the circuit breaker body, providing appropriate buffering and deceleration, thus reducing the possibility of damage to the circuit breaker body.

[0007] Preferably, the end of the elastic telescopic rod away from the moving block is fitted onto the inner wall of the hydraulic chamber.

[0008] Preferably, the force-bearing block is located at the top of the extrusion arc rod and near the side, and the force-bearing block is in contact with the extrusion arc rod.

[0009] Preferably, the auxiliary limiting component includes a second hydraulic chamber mounted on the inner wall side of the switchgear body. A rotating pressing block is mounted on the side of the rotating rod. One end of the second hydraulic chamber is slidably connected to a force-bearing rod via a piston, and the other end of the second hydraulic chamber is slidably connected to a limit rod via a piston. A spring is mounted on the side of the limit rod. By setting up the auxiliary limiting component, when the rotating pressing block moves to a position on the force-bearing rod, the limit rod moves into a fixed slide rail, thus preventing the circuit breaker body from continuing to move forward. This prevents the circuit breaker body from accidentally falling when directly pulled out, improving the protective effect of the device on the circuit breaker body.

[0010] Preferably, the side of the fixed slide rail has a through opening, the cross-sectional shape of which is adapted to the cross-sectional shape of the limiting rod.

[0011] Preferably, the end of the spring away from the limiting rod is fitted onto the inner wall of the hydraulic chamber.

[0012] Preferably, the auxiliary adsorption assembly includes a suction cup mounted on the side of the friction block, a pneumatic rod mounted at the bottom of the first force-bearing rod, a first pneumatic chamber mounted on the side of the fixed slide rail, a pneumatic hose connected to the first pneumatic chamber mounted on the side of the first pneumatic chamber, and a second pneumatic chamber mounted inside the friction block. By configuring the auxiliary adsorption assembly, when the circuit breaker body moves rapidly forward to the suction cup on the side of the friction block, the adsorption effect of the suction cup on the circuit breaker body is improved, further preventing the circuit breaker body from being directly pulled out of the switch cabinet body.

[0013] Preferably, the pneumatic rod passes through the pneumatic chamber and is slidably connected to the pneumatic chamber via a piston.

[0014] Preferably, the end of the air pressure hose furthest from the first air pressure chamber is fitted to the side of the second air pressure chamber and is connected to the second air pressure chamber.

[0015] This invention provides an adjustable high and low voltage switchgear. It has the following advantages: (1) When the adjustable high and low voltage switchgear is accidentally pushed into or pulled out quickly, it can drive the rotating rod to rotate quickly. In conjunction with the hydraulic chamber one, moving block, elastic telescopic rod, extrusion arc rod, torsion spring rod, transmission rod one, force block and transmission rod two, the friction block moves out from the fixed slide rail and contacts the side of the circuit breaker body to buffer and decelerate it accordingly, reducing the possibility of damage to the circuit breaker body.

[0016] (2) When the circuit breaker body moves forward, the rotating pressing block mounted on the side of the rotating rod moves along with it. When the rotating pressing block moves to the force rod, it works with the hydraulic chamber 2 and the spring 1 to move the limit rod into the fixed slide rail, which can prevent the circuit breaker body from moving forward and prevent the circuit breaker body from falling accidentally when it is directly pulled out, thus improving the protection effect of the device on the circuit breaker body.

[0017] (3) When the circuit breaker body moves forward quickly to the suction cup on the side of the friction block, it can be initially attracted by the suction cup. At this time, the force rod is squeezed and moves. With the help of the pneumatic rod, pneumatic chamber one, pneumatic hose and pneumatic chamber two, the suction effect of the suction cup on the circuit breaker body can be improved under this condition, and the circuit breaker body is further prevented from being directly pulled out from the switch cabinet body.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1, please refer to Figures 1-5 An adjustable high and low voltage switchgear includes: The switch cabinet body 100 has a fixed slide rail 200 inside, and the top of the fixed slide rail 200 is slidably connected to the circuit breaker body 300. Moving contact 400 is mounted on the side of the circuit breaker body 300, and stationary contact 500 is mounted inside the switch cabinet body 100. A rotating rod 601 is mounted on the side of the circuit breaker body 300. A torsion spring rod 606 is rotatably connected inside the switch cabinet body 100. A transmission component for transmission is mounted between the rotating rod 601 and the torsion spring rod 606. The transmission component includes a hydraulic chamber 602 mounted on the outside of the rotating rod 601. A moving block 603 is slidably connected inside the hydraulic chamber 602 via a piston. An elastic telescopic rod 604 is mounted on the side of the moving block 603. The end of the elastic telescopic rod 604 away from the moving block 603 is mounted on the inner wall of the hydraulic chamber 602. When the circuit breaker body 300 is accidentally pushed in or pulled out quickly, it will cause the rotating rod 601 to rotate quickly. The rotating rod 601 will then cause the hydraulic chamber 602 mounted on its outer side to rotate quickly. The moving block 603 inside the hydraulic chamber 602 can stretch the elastic telescopic rod 604 under the action of centrifugal force and move along the hydraulic chamber 602. The moving block 603 and the hydraulic chamber 602 are connected by a piston sliding connection, so that when the moving block 603 moves, it can push the oil originally stored in the hydraulic chamber 602.

[0022] A compression arc rod 605 is slidably connected to the side of hydraulic chamber 602 via a piston. A transmission rod 607 is fixedly connected to the top of torsion spring rod 606. A force-receiving block 608 is hinged to the side of transmission rod 607. The force-receiving block 608 is located at the top of the compression arc rod 605 and close to its side, and is in contact with the compression arc rod 605. A transmission rod 609 is fixedly connected to the bottom of torsion spring rod 606, and a friction block 610 is hinged to the side of transmission rod 609. When oil flows towards the side closer to the compression arc rod 605, the compression arc rod 605, which rotates with hydraulic chamber 602, extends synchronously from the hydraulic chamber 602, thereby compressing the force-receiving block 608 at its top. This causes the force-receiving block 608 to move the transmission rod 607, which is hinged to it, away from the compression arc rod 605. Figure 4 As shown, transmission rod 607 drives torsion spring rod 606, which is fixedly connected to it, to rotate clockwise at a certain angle. This causes torsion spring rod 606 to drive transmission rod 609, which is fixedly connected to it, to rotate clockwise at a certain angle. Transmission rod 609 then drives friction block 610 located on its side to move. At this time, friction block 610 moves out from the fixed slide rail 200 and contacts the side of the circuit breaker body 300, providing corresponding buffering and deceleration to reduce the possibility of damage to the circuit breaker body 300.

[0023] As the moving speed of the circuit breaker body 300 decreases, the rotation speed of the rotating rod 601 and the hydraulic chamber 602 also decreases. The moving block 603 loses the effect of centrifugal force and can be reset under the action of the elastic telescopic rod 604. Similarly, the pressing arc rod 605 is reset. The force block 608 and the transmission rod 607 lose the effect of the pressing arc rod 605 and can be reset under the action of the torsion spring rod 606. Similarly, the friction block 610 is reset.

[0024] In use, if the circuit breaker body 300 is accidentally pushed in or pulled out quickly, it will cause the rotating rod 601 to rotate rapidly. The rotating rod 601 will then cause the hydraulic chamber 602 mounted on its outer side to rotate rapidly. The moving block 603 inside the hydraulic chamber 602 will stretch the elastic telescopic rod 604 under the action of centrifugal force and move along the hydraulic chamber 602. The moving block 603 and the hydraulic chamber 602 are connected by a piston sliding connection, so that when the moving block 603 moves, it can push the oil originally stored in the hydraulic chamber 602, causing the oil to flow towards the side closer to the extrusion arc rod 605. The extrusion arc rod 605, which rotates with the hydraulic chamber 602, extends synchronously from the hydraulic chamber 602, which is connected to it by a piston, thereby extruding the force block 608 located at its top position. This causes the force block 608 to drive the transmission rod 607, which is hinged to it, to move away from the extrusion arc rod 605. Figure 4 As shown, transmission rod 607 drives torsion spring rod 606, which is fixedly connected to it, to rotate clockwise at a certain angle. This causes torsion spring rod 606 to drive transmission rod 609, which is fixedly connected to it, to rotate clockwise at a certain angle. Transmission rod 609 then drives friction block 610 located on its side to move. At this time, friction block 610 moves out from the fixed slide rail 200 and contacts the side of the circuit breaker body 300, providing corresponding buffering and deceleration. As the moving speed of the circuit breaker body 300 decreases, the rotation speed of the rotating rod 601 and the hydraulic chamber 602 also decreases. The moving block 603 loses the effect of centrifugal force and can be reset under the action of the elastic telescopic rod 604. Similarly, the pressing arc rod 605 is reset. The force block 608 and the transmission rod 607 lose the effect of the pressing arc rod 605 and can be reset under the action of the torsion spring rod 606. Similarly, the friction block 610 is reset.

[0025] Example 2, please refer to Figures 1-7Based on Embodiment 1, the top of the fixed slide rail 200 is equipped with an auxiliary limiting component 700 for limiting the circuit breaker body 300. The auxiliary limiting component 700 includes a hydraulic chamber 2 701 mounted on the inner wall side of the switch cabinet body 100, and a rotating pressing block 702 mounted on the side of the rotating rod 601. One end of the hydraulic chamber 2 701 is slidably connected to a force-bearing rod 1 703 via a piston. When the circuit breaker body 300 moves forward, the rotating pressing block 702 mounted on the side of the rotating rod 601 moves along with it. When the rotating pressing block 702 moves to the force-bearing rod 1 703, it can press the force-bearing rod 1 703 and drive it to move to the side a certain distance. In conjunction with the hydraulic chamber 2 701 which is slidably connected to the force-bearing rod 1 703 via a piston, the force-bearing rod 1 703 pushes the oil originally stored in the hydraulic chamber 2 701 during its movement.

[0026] The other end of the hydraulic chamber 701 is connected to a limit rod 704 via a piston. A through opening is provided on the side of the fixed slide rail 200, the cross-sectional shape of which matches the cross-sectional shape of the limit rod 704. A spring 705 is mounted on the side of the limit rod 704, with the end of the spring 705 away from the limit rod 704 mounted on the inner wall of the hydraulic chamber 701. When the oil originally stored in the hydraulic chamber 701 is pushed, the oil moves towards the limit rod 704, causing the limit rod 704, which is connected to the hydraulic chamber 701 via a piston, to extend out of the hydraulic chamber 701. The limit rod 704 moves into the fixed slide rail 200, thus preventing the switchgear body 100 from moving further forward and preventing the circuit breaker body 300 from accidentally falling if directly pulled out, thereby improving the protection effect of the device for the circuit breaker body 300.

[0027] When the circuit breaker body 300 moves backward, the rotating pressing block 702 moves away from the pressing rod 703, causing the pressing rod 703 to lose its restriction. Similarly, the limiting rod 704 loses its restriction and can be reset under the action of the spring 705.

[0028] In use, based on Embodiment 1, when the circuit breaker body 300 moves forward, the rotating pressing block 702 mounted on the side of the rotating rod 601 moves along with it. When the rotating pressing block 702 moves to the force rod 703, it can press the force rod 703 and drive the force rod 703 to move to the side a certain distance. In conjunction with the hydraulic chamber 701 which is slidably connected to the force rod 703 by a piston, the force rod 703 pushes the oil originally stored in the hydraulic chamber 701 during the movement. The oil then moves towards the side closer to the limit rod 704, causing the limit rod 704 which is slidably connected to the hydraulic chamber 701 by a piston to extend out of the hydraulic chamber 701. The limit rod 704 moves into the fixed slide rail 200, which can prevent the switch cabinet body 100 from continuing to move forward. When the circuit breaker body 300 moves backward, the rotating pressing block 702 moves away from the pressing rod 703, causing the pressing rod 703 to lose its restriction. Similarly, the limiting rod 704 loses its restriction and can be reset under the action of the spring 705.

[0029] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, the side of the friction block 610 is equipped with an auxiliary adsorption assembly 800 for limiting the circuit breaker body 300. The auxiliary adsorption assembly 800 includes a suction cup 801 mounted on the side of the friction block 610, and a pneumatic rod 802 mounted on the bottom of the force-bearing rod 703. When the circuit breaker body 300 moves forward rapidly to the suction cup 801 on the side of the friction block 610, it can be initially adsorbed by the suction cup 801. At this time, the force-bearing rod 703 is squeezed and moves, which in turn drives the pneumatic rod 802 fixedly connected to it to move.

[0030] A pneumatic chamber 803 is mounted on the side of the fixed slide rail 200. A pneumatic rod 802 passes through the pneumatic chamber 803 and is slidably connected to the pneumatic chamber 803 by a piston. A pneumatic hose 804 connected to the side of the pneumatic chamber 803 is mounted on the side of the pneumatic chamber 803. A second pneumatic chamber 805 is mounted inside the friction block 610. The end of the pneumatic hose 804 away from the pneumatic chamber 803 is mounted on the side of the second pneumatic chamber 805 and is connected to the second pneumatic chamber 805. When the pneumatic rod 802 moves away from the first pneumatic chamber 803, it can draw gas from the first pneumatic chamber 803 and, through the pneumatic hose 804 connected to the first pneumatic chamber 803, draw gas from the second pneumatic chamber 805. This allows residual gas between the suction cup 801 and the circuit breaker body 300 to be drawn into the second pneumatic chamber 805. Furthermore, when the circuit breaker body 300 slows down, the suction cup 801 returns to its original position along with the friction block 610, and at this time, it will not adhere to the circuit breaker body 300. Similarly, when the first force rod 703 returns to its original position, it will not draw residual gas between the suction cup 801 and the circuit breaker body 300 into the second pneumatic chamber 805. This improves the adhesion of the suction cup 801 to the circuit breaker body 300, further preventing the circuit breaker body 300 from being directly pulled out of the switchgear body 100.

[0031] In use, based on Embodiment 1 and Embodiment 2, when the circuit breaker body 300 moves forward quickly to the suction cup 801 on the side of the friction block 610, it can be initially attracted by the suction cup 801. At this time, the force rod 703 is squeezed and moves. The force rod 703 can drive the pneumatic rod 802 fixedly connected to it to move. The pneumatic rod 802 and the pneumatic chamber 803 are connected by a piston sliding connection, so that when the pneumatic rod 802 moves away from the pneumatic chamber 803, it can draw the gas in the pneumatic chamber 803 and draw the gas in the pneumatic chamber 805 through the pneumatic hose 804 connected to the pneumatic chamber 803. Thus, the residual gas between the suction cup 801 and the circuit breaker body 300 is drawn into the pneumatic chamber 805 through the pneumatic chamber 805. Furthermore, when the speed of the circuit breaker body 300 slows down, the suction cup 801 resets along with the friction block 610. At this time, it will not attract the circuit breaker body 300. Similarly, when the force rod 703 resets, it will not extract the residual gas between the suction cup 801 and the circuit breaker body 300 into the pressure chamber 805.
