[0029] Embodiment 1

[0030] See also Figure 1-Figure 2 As shown in the figure, an operating mechanism for a high-voltage fixed cabinet includes a panel 100, a position indicator 200 is fixedly installed on the side of the panel 100, a mechanism handle 300 is slidably connected inside the panel 100 and penetrated, the mechanism handle 300 is located at the side of the position indicator 200, a scratch plate 400 is installed at the bottom of the mechanism handle 300, an isolation operating shaft 500 is installed at the rear end of the panel 100, and a grounding operating shaft 600 is installed at the rear end of the panel 100. The operating mechanism has four positions: working position, isolation operation, grounding operation, and maintenance position. The working position is to disconnect the circuit breaker, and the mechanism handle 300 moves to the isolation operation position (the circuit breaker is not disconnected, and the mechanism handle 300 cannot move). After the isolation disconnection is operated, the mechanism handle 300 automatically moves to the grounding operation position. After the grounding switch is closed, the mechanism handle 300 automatically moves to the maintenance position before the door can be opened. During the operation process, the interlocking plate moves to block the unoperated or to-be-operated holes, meeting the five protections. Therefore, the device has a simple structure and a small size, ensures the operation sequence, and is difficult to operate incorrectly.

[0031] When in use, the mechanism handle 300 moves to the isolation operation position. The circuit breaker is not opened and the mechanism handle 300 cannot move. After the isolation opening operation is performed, the mechanism handle 300 automatically moves to the grounding operation position. After the grounding switch is closed, the mechanism handle 300 automatically moves to the maintenance position before the door can be opened.

[0032] To improve the stability of the operating mechanism when installed on a fixed cabinet, refer to Figure 1-Figure 4As shown in the figure, the panel 100 is provided with an adsorption assembly 700, which includes a hydraulic chamber 701. The panel 100 is provided with a through opening, and the cross section of the opening is the same as the cross section of the hydraulic chamber 701 at the opening. The piston at one end of the hydraulic chamber 701 is slidably connected to a force rod 702, and the piston at the other end of the hydraulic chamber 701 is slidably connected to a push rod 703. The bottom of the force rod 702 is fixedly connected to a spring 704, one end of the spring 704 is connected to the force rod 702, and the other end of the spring 704 is connected to the inner wall of the hydraulic chamber 701. When the mechanism handle 300 is in the working position on the position indicator 200, the mechanism handle 300 squeezes the force rod 702, so that the force rod 702 squeezes the spring 704 fixed thereto and moves downward. The rear end of the push rod 703 is fixedly connected with a suction cup 705, and the front end of the suction cup 705 is fixedly connected with an air storage bag 706. A groove is provided on the side of the panel 100, and the air storage bag 706 is located in the groove of the panel 100. The side of the air storage bag 706 is slidably connected with a gas pressure rod 707 by setting a gas pressure chamber piston. When the force rod 702 moves downward, it cooperates with the hydraulic chamber 701 that is slidably connected to the piston of the force rod 702, so that the pressure in the hydraulic chamber 701 increases, driving the push rod 703 that is slidably connected to the piston of the hydraulic chamber 701 to move, so that the push rod 703 drives the suction cup 705 that is fixedly connected to it to move, and the suction cup 705 moves out of the panel 100 to absorb the fixed cabinet, which can improve the stability of the operating mechanism installed on the fixed cabinet, making the device easier to use. When it is necessary to disassemble and overhaul it, first push the pneumatic rod 707 to pass the gas in the air bag 706 into the suction cup 705, so that it cannot adsorb the fixed cabinet, and then put the mechanism handle 300 in the overhaul position, so that the force rod 702 is no longer restricted and moves upward under the action of the spring 704. Similarly, the suction cup 705 can be reset under the action of the push rod 703, so as to carry out overhaul, which further improves the usability of the device.

[0033] When in use, when the mechanism handle 300 is in the working position on the position indicator plate 200, the mechanism handle 300 squeezes the force-bearing rod 702, so that the force-bearing rod 702 squeezes the spring 704 fixed thereto and moves downward, and cooperates with the hydraulic chamber 701 slidably connected to the piston of the force-bearing rod 702, so that the pressure in the hydraulic chamber 701 increases, driving the push rod 703 slidably connected to the piston of the hydraulic chamber 701 to move, so that the push rod 703 drives the suction cup 705 fixed thereto to move, and the suction cup 705 moves out of the panel 100 to adsorb the fixed cabinet; when it is necessary to disassemble and overhaul it, first push the gas pressure rod 707 to pass the gas in the air bag 706 into the suction cup 705, so that it cannot adsorb the fixed cabinet, and then put the mechanism handle 300 in the overhaul position, so that the force-bearing rod 702 loses its restriction and moves upward under the action of the spring 704. Similarly, the suction cup 705 can be reset under the action of the push rod 703, so as to carry out overhaul.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
