Description

Technical Field

[0001] The utility model relates to the technical field of anti-electric shock isolation mechanisms, in particular to an automatic anti-electric shock isolation mechanism for a low-voltage power distribution cabinet when in contact with water. Background Art

[0002] With the development of society and the continuous improvement of people's living standards, electricity has been vigorously developed, making the role of electricity more and more complex and frequent. Now, whether it is urban buildings, factory buildings, or self-built houses in rural areas, as the functions increase, distribution cabinets are needed for power distribution. If the distribution cabinet is not connected tightly during power distribution, it is easy to rub against the connecting switch, causing the distribution cabinet to catch fire. Sometimes the external indicating instrument of the distribution cabinet leaks electricity, causing the staff to be electrocuted when touching the instrument, causing great harm to the staff.

[0003] A Chinese patent discloses an anti-electric shock distribution cabinet (authorization announcement number CN218867665U). The patented technology can include a protection box and a distribution cabinet body. Dust-proof nets are set on both sides of the protection box, penetrating the protection box and fixedly connected to the penetration part. One side of the two dust-proof nets is set with a mounting frame fixedly connected to the inside of the protection box. Two bearing cylinders are set inside the mounting frame, which are fixedly connected to the inside of the mounting frame through mounting rods. A rotating rod is fixedly connected to the inside of the bearing cylinder, and a gear is fixedly connected to the surface of the rotating rod. One end of each rotating rod is fixedly connected to an exhaust fan, and one side of the two mounting frames is set with a motor fixedly connected to the inside of the protection box. The anti-electric shock distribution cabinet described in the utility model can, on the one hand, have a good heat dissipation effect on the distribution cabinet body, and on the other hand, it can prevent external dust and moisture from entering the inside of the protection box, thereby affecting the distribution cabinet body placed inside.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the existing anti-electric shock distribution cabinet cannot adjust the grounding wire, causing the grounding wire to be unable to contact the ground, so that the current on the surface of the box cannot be introduced into the ground, which can easily cause harm to construction workers, and the anti-electric shock distribution cabinet cannot quickly replace the moisture-proof block to prevent the moisture-proof block from failing due to long-term use, resulting in a decrease in the moisture-proof performance of the box.

[0024] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] The following specifically describes the specific settings and functions of adjusting the surface of the grounding wire 7 to be inserted into the ground to prevent the staff from getting an electric shock and replacing the moisture-proof block 25 to prevent the moisture-proof block 25 from losing its moisture-proof effect after long-term use.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in this embodiment: when the staff needs to adjust the surface of the grounding wire 7 to be inserted into the ground to conduct the current into the earth to prevent the staff from being electrocuted, the staff pulls the pull rod 13 outward, and the pull rod 13 is subjected to the pulling force to drive the rotating block 12 to move outward. As the rotating block 12 moves outward, the rotating block 12 drives the surface of the sliding block 11 to slide outward on the inner cavity surface of the sleeve 9, and the sliding block 11 drives the surface of the insertion rod 14 to gradually separate from the inner cavity surface of the socket 15. At this time, the telescopic rod 6 will not be constrained by the insertion rod 14 and can move downward. The staff pulls the telescopic rod 6 downward, and as the telescopic rod 6 moves downward, the telescopic rod 6 drives the surface of the grounding wire 7 to be inserted into the ground. The ground is provided with the above-mentioned structure, so that the staff can adjust the ground wire 7 conveniently, so that the surface of the ground wire 7 is inserted into the ground to conduct the current on the surface of the chassis into the ground, so as to prevent the chassis from leaking electricity and accidentally injuring the construction staff. The front end of the sliding block 11 is fixedly connected with the plug rod 14, and the surface of the rear end of the telescopic rod 6 is provided with a hole 15. The number of the holes 15 is several and evenly distributed on the surface of the rear end of the telescopic rod 6. The inner cavity of the hole 15 is slidably connected with the surface of the plug rod 14. The staff pulls the pull rod 13 outward to make the surface of the plug rod 14 gradually separate from the inner cavity of the hole 15. At this time, the telescopic rod 6 will not be bound by the plug rod 14 and can be adjusted and moved up and down through the plug rod 14.The arrangement of the jack 15 and other structures makes it easy for the staff to quickly limit and fix the telescopic rod 6, so as to prevent the telescopic rod 6 from being affected by external forces and driving the surface of the grounding wire 7 off the ground, and failing to achieve the anti-electric shock effect. The surface of the rear end of the arc block 8 is fixedly connected with a tension spring 16, and the rear end of the tension spring 16 is fixedly connected to the surface of the front end of the sliding block 11, and the inner diameter of the tension spring 16 is slidably connected to the surface of the insertion rod 14. The staff pulls the pull rod 13 outward to make the surface of the sliding block 11 slide outward on the surface of the inner cavity of the sleeve 9, and the sliding block 11 drives the tension spring 16 to move outward and pulls When the staff needs to keep the insertion rod 14 inserted into the inner cavity of the socket 15, the staff releases the tension on the pull rod 13, so that the tension spring 16 releases the accumulated force and drives the surface of the sliding block 11 to slide inward on the inner cavity surface of the sleeve 9, and at the same time drives the surface of the insertion rod 14 to be continuously inserted into the inner cavity of the socket 15. By setting the tension spring 16, the surface of the insertion rod 14 is continuously inserted into the inner cavity surface of the socket 15, preventing the insertion rod 14 from being affected by external force and escaping from the inner cavity of the socket 15, and the telescopic rod 6 cannot be limited and fixed. Two first sliding grooves 17 are provided inside the hollow rod 5, and the telescopic rod 6 can be fixed. The surfaces of both sides of the rod 6 are fixedly connected with first sliders 18. There are two first sliders 18 and they are evenly distributed on the surfaces of both sides of the telescopic rod 6. The surfaces of the first sliders 18 are slidably connected with the inner cavity surfaces of the first slide grooves 17. When the staff pulls the telescopic rod 6 downward, the surface of the first slider 18 is driven by the pulling force to slide downward in the inner cavity of the first slide grooves 17. Through the arrangement of the first slide grooves 17, the first sliders 18 and other structures, when the staff pulls the telescopic rod 6 downward, the moving track of the telescopic rod 6 is in the same horizontal direction, so as to prevent the telescopic rod 6 from shaking and prevent the rod 1 from being inserted. 4 cannot be inserted into the inner cavity of the jack 15, and the surface of the top of the inner cavity of the hollow rod 5 is fixedly connected with a rebound spring 19, and the bottom end of the rebound spring 19 is fixedly connected to the surface of the top of the hollow rod 5. The staff pulls the telescopic rod 6 downward to move the telescopic rod 6 downward, driving the rebound spring 19 to move downward and stretching the rebound spring 19 to store force. When the staff needs to move the telescopic rod 6 upward, the staff releases the pulling force on the telescopic rod 6 to release the stored force of the rebound spring 19 to drive the surface of the telescopic rod 6 to slide upward in the inner cavity of the hollow rod 5 and drive the surface of the ground wire 7 off the ground. Through the setting of the rebound spring 19, the telescopic rod 6 continues to move upward under the rebound force of the rebound spring 19 to drive the surface of the ground wire 7 off the ground, which is convenient for the staff to store and adjust the ground wire 7.

[0028] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, in this embodiment: two air inlet plates 20 are fixedly connected to the surfaces of both sides of the box body 1, and fixed shells 21 are fixedly connected to the surfaces of both sides of the inner cavity of the box body 1. The number of fixed shells 21 is two and they are evenly distributed on the surfaces of both sides of the inner cavity of the box body 1. A plurality of evenly distributed air inlet holes 22 are opened on the surfaces of both sides of the fixed shell 21. A sliding plate 23 is slidably connected to the interior of the fixed shell 21, and a pull ring 24 is fixedly connected to the surface of the front end of the sliding plate 23. A moisture-proof block 25 is installed in the inner cavity of the sliding plate 23. The surfaces of the top and bottom ends of the inner cavity of the fixed shell 21 are fixedly connected to the inner cavity of the fixed shell 21. The second slide grooves 26 are provided on the surfaces of the top and bottom ends of the inner cavity of the fixed shell 21. The surfaces of the top and bottom ends of the sliding plate 23 are fixedly connected with second sliders 27. The surfaces of the second sliders 27 are slidably connected with the inner cavity surfaces of the second slide grooves 26. When the staff needs to quickly replace the moisture-proof block 25, the staff pulls the pull ring 24 outwards. The pull ring 24 is subjected to the tension to drive the surface of the sliding plate 23 to slide outward in the inner cavity of the fixed shell 21, and at the same time drives the surface of the second slider 27 to slide in the inner cavity of the fixed shell 21. The second slide groove 26 slides outward in the inner cavity. As the second slider 27 moves outward, the second slider 27 drives the tension spring 28 to move outward while stretching and storing force. As the sliding plate 23 gradually moves outward, the sliding plate 23 drives the moisture-proof block 25 to gradually separate from the inner cavity of the fixed shell 21. Through the arrangement of the above structure, it is convenient for the staff to quickly replace the moisture-proof block 25 to prevent the moisture-proof block 25 from losing its moisture-proof effect after long-term use. The surface of the rear end of the inner cavity of the second slide groove 26 is fixedly connected with the tension spring 28. The front end of the tension spring 28 is connected to the second slide groove 26. The surface of the rear end of the block 27 is fixedly connected. The staff pulls the pull ring 24 outward, so that the second slider 27 drives the tension spring 28 to move outward and simultaneously performs tensioning and force accumulation. When the staff needs to reset the sliding plate 23, the staff releases the pulling force on the pull ring 24, so that the tension spring 28 releases the force accumulation and drives the surface of the second slider 27 to move inward in the inner cavity of the second slide groove 26, and at the same time drives the surface of the sliding plate 23 to move inward in the inner cavity of the fixed shell 21. Through the setting of the tension spring 28, the staff can easily reset the sliding plate 23 quickly.

[0029] The practical working principle of the present invention is that when the staff needs to adjust the surface of the grounding wire 7 to insert it into the ground to guide the current into the ground to prevent the staff from getting an electric shock, the staff pulls the pull rod 13 outwards, and the pull rod 13 is subjected to the pulling force to drive the rotating block 12 to move outwards. As the rotating block 12 moves outwards, the rotating block 12 drives the surface of the sliding block 11 to slide outwards on the inner cavity surface of the sleeve 9, and the sliding block 11 drives the surface of the plug rod 14 to gradually separate from the inner cavity surface of the socket 15. At this time, the telescopic rod 6 will not be bound by the plug rod 14 and can move downward. The staff pulls the telescopic rod 6 downwards, and as the telescopic rod 6 moves downwards, the telescopic rod 6 drives the surface of the grounding wire 7 to insert into the ground. Through the arrangement of the above structure, it is convenient for the staff to adjust the grounding wire 7 so that the surface of the grounding wire 7 is inserted into the ground to guide the current on the surface of the chassis into the ground, thereby preventing the chassis from accidentally injuring the construction personnel due to leakage. When the staff needs to adjust the moisture-proof block 25 When performing quick replacement, the staff pulls the pull ring 24 outward, and the pull ring 24 is subjected to the tension to drive the surface of the sliding plate 23 to slide outward in the inner cavity of the fixed shell 21, and at the same time drives the surface of the second sliding block 27 to slide outward in the inner cavity of the second sliding groove 26. As the second sliding block 27 moves outward, the second sliding block 27 drives the tension spring 28 to move outward while stretching and accumulating force. As the sliding plate 23 gradually moves outward, the sliding plate 23 drives the moisture-proof block 25 to gradually separate from the inner cavity of the fixed shell 21. Through the arrangement of the above-mentioned structure, it is convenient for the staff to quickly replace the moisture-proof block 25 to prevent the moisture-proof block 25 from losing its moisture-proof effect due to long-term use.
