DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] like Figure 1-Figure 4As shown, an electrical switch cabinet for synchronously opening and closing an earthing switch comprises a cabinet body 1, a cabinet cover 2 is rotatably mounted on the surface of the cabinet body 1, an earthing switch 3 is fixedly mounted inside the cabinet body 1, a first conductive sheet 4 is fixedly mounted on the surface of the earthing switch 3 via an L-shaped connecting block 17, a second conductive sheet 5 is fixedly mounted on the bottom of the cabinet body 1, and an earthing wire is fixedly mounted on the surface of the second conductive sheet 5. When the first conductive sheet 4 and the second conductive sheet 5 are connected to each other, the earthing switch 3 is opened, otherwise it is closed.
[0020] A fixed block 6 is fixedly installed in the cabinet body 1, and a sliding hole is provided on the surface of the fixed block 6. A moving rod 7 is slidably installed in the sliding hole, and a conductive block 8 is fixedly installed at one end of the moving rod 7. A first telescopic spring 19 is fixedly installed between the moving rod 7 and the cabinet body 1, and a spring rod 9 is fixedly installed at one end of the moving rod 7 away from the first telescopic spring 19. A moving groove is provided in the cabinet body 1, and one end of the spring rod 9 is slidably inserted in the moving groove. A limiting groove is provided in the moving groove. A rotating hole is provided on the surface of the cabinet cover 2, and a rotating rod 10 is inserted in the rotating hole. A pressing rod 11 is fixedly installed at one end of the rotating rod 10. A through hole connected to the limiting groove is provided on the surface of the cabinet body 1, and a push rod 12 is fixedly installed on the surface of the cabinet cover 2, and one end of the push rod 12 is inserted into the through hole. The longitudinal section of the push rod 12 is trapezoidal, and the inclined end of the push rod 12 is in sliding contact with one end of the spring rod 9.
[0021] When the electrical switch cabinet needs to be maintained and the grounding switch 3 needs to be opened, the staff first drives the pressure rod 11 to rotate clockwise through the rotating rod 10, and the pressure rod 11 contacts the moving rod 7, so that the pressure rod 11 drives the moving rod 7 to move vertically downward under the action of the fixed block 6, and the first telescopic spring 19 is compressed, and then the moving rod 7 drives the conductive block 8 to move toward the second conductive sheet 5 until it contacts the second conductive sheet 5 and also contacts the first conductive sheet 4, and then the grounding switch 3 is opened through the action of the conductive block 8. When the conductive block 8 contacts the second conductive sheet 5, the spring rod 9 just moves The cabinet cover 2 moves to the limit groove and contacts the push rod 12, and then the cabinet cover 2 is opened, the push rod 12 is pulled out of the through hole, and then the spring rod 9 is completely inserted into the limit groove, and the movable rod 7 is fixed through the interaction between the limit groove and the spring rod 9. After maintenance, the cabinet cover 2 is first closed, and the push rod 12 is inserted into the limit groove through the through hole. The spring rod 9 is compressed through the mutual squeezing of the inclined ends and then moved out of the limit groove. Then, under the action of the first telescopic spring 19, the movable rod 7 moves vertically upward, and the first conductive sheet 4 is disconnected from the second conductive sheet 5, thereby realizing the closing of the grounding switch 3.
[0022] A handle 13 is fixedly installed at one end of the rotating rod 10 away from the pressure rod 11, and a second telescopic spring 20 is sleeved on the surface of the rotating rod 10. The two ends of the second telescopic spring 20 are respectively fixedly connected to the handle 13 and the cabinet cover 2. A baffle 14 is fixedly installed in the cabinet body 1, and a slot is opened on the surface of the baffle 14. The pressure rod 11 is located in the slot. When opening the cabinet cover 2, the handle 13 is first pressed to compress the second telescopic spring 20, and the pressure rod 11 is driven by the rotating rod 10 to move away from the slot. The positioning effect of the slot on the pressure rod 11 is released, and then the cabinet cover 2 can be opened.
[0023] The surface of the moving rod 7 is symmetrically provided with sliding grooves, and limit blocks 15 are slidably installed in the two sliding grooves. The two limit blocks 15 are fixedly connected to the inner wall of the sliding hole. When the moving rod 7 moves, the two limit blocks 15 and the sliding grooves can limit the rotation of the moving rod 7.
[0024] Support blocks 18 are symmetrically fixedly installed in the cabinet 1, and a dustproof plate 16 is fixedly installed between the two support blocks 18. The dustproof plate 16 is located above the grounding switch 3. During maintenance, the dustproof plate 16 can prevent impurities from falling onto the grounding switch 3, thereby affecting the use of the grounding switch 3.
[0025] When in use, the staff first drives the pressure rod 11 to rotate clockwise through the rotating rod 10, and drives the moving rod 7 to move vertically downward through the pressure rod 11, and the first telescopic spring 17 is compressed, thereby driving the conductive block 8 to contact the second conductive sheet 5 and the first conductive sheet 4, and the grounding switch 3 is opened. The spring rod 9 just moves to the limit groove and contacts the top rod 12, and then the cabinet cover 2 is opened, and the spring rod 9 is completely inserted into the limit groove. After maintenance, first close the cabinet cover 2, insert the top rod 12 through the through hole into the limit groove, and the spring rod 9 is compressed through the mutual squeezing of the inclined ends. Then, under the action of the elastic force of the first telescopic spring 17, the moving rod 7 moves vertically upward, and the first conductive sheet 4 is disconnected from the second conductive sheet 5, thereby achieving the closing of the grounding switch 3.
[0026] In general, regarding the technical problem: when the staff opens the electrical switch cabinet for maintenance, they often forget to open the grounding switch 3 and carry out maintenance directly, which inevitably brings danger to the staff at work. At the same time, after the maintenance is completed, they often forget to close the grounding switch 3; adopting a technical solution: through the cooperation of the moving rod 7, the conductive block 8, the pressure rod 11, the first conductive sheet 4, the second conductive sheet 5, the first telescopic spring 17, the spring rod 9 and the top rod 12, the grounding switch 3 can be opened at the same time when the electrical switch cabinet is opened, and the grounding switch 3 can be closed at the same time when the electrical switch cabinet is closed; because the implementation process of the technical solution is: the staff first drives the pressure rod 11 to rotate clockwise through the rotating rod 10, drives the moving rod 7 to move vertically downward through the pressure rod 11, and the first telescopic spring 17 compresses the grounding switch 3. , and then drive the conductive block 8 to contact the second conductive sheet 5 and the first conductive sheet 4, the grounding switch 3 is opened, the spring rod 9 just moves to the limit groove and contacts the top rod 12, and then the cabinet cover 2 is opened, the spring rod 9 is completely inserted into the limit groove, after maintenance, first close the cabinet cover 2, insert the top rod 12 through the through hole into the limit groove, through the mutual squeezing of the inclined ends, the spring rod 9 is compressed, and then under the action of the elastic force of the first telescopic spring 17, the moving rod 7 moves vertically upward, the first conductive sheet 4 is disconnected from the second conductive sheet 5, and then the grounding switch 3 is closed; this will inevitably solve the technical problem, and the technical effect achieved is: preventing the staff from forgetting to open the grounding switch 3 during maintenance, and forgetting to close the grounding switch 3 after the maintenance is completed, which greatly reduces the danger brought by the staff at work.
[0027] 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.
