Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, and particularly relates to a grounding protection device for electric power construction. Background Art

[0002] Grounding protection is an important measure for ensuring the safety of electrical equipment and personnel. When a leakage fault occurs in the equipment, the current can flow into the ground through the conducting wire, so that the outer shell of the equipment is no longer charged, preventing personnel from electric shock and equipment damage.

[0003] After retrieval, it is found that the technical solution provided by the utility model with the application number CN202321327781.6 includes a first conductive plate, a fixing plate and a fixing ring. Second conductive plates are installed on both sides of the first conductive plate, and grounding bolts are arranged at the tops of the second conductive plates. A conductive column is installed at the top of the first conductive plate, and a protective cover is arranged above the conductive column. Connecting plates are installed on both sides of the protective cover, and nuts are arranged at the tops of the connecting plates. Connecting screws are installed at the bottoms of the nuts, and nuts are threadedly connected to the outer walls of the connecting screws below the first conductive plate. A conducting wire is wound around the outer wall of the conductive column. This solution fixes the conducting wire through the fixing ring, realizes the fixation of the conducting wire, changes the stress point during the pulling process of the conducting wire, and prevents the connection between the conducting wire and the conductive column from falling off during the climbing process of construction workers, but the diameter of the conducting wire is thin, and the components such as the fixing ring and the one-way threaded rod knob arranged on one side are small in size. It takes a certain amount of time to rotate the knob during rotation, or an external tool needs to be used to rotate it, which is rather troublesome and takes a long time to fix the conducting wire.

The role of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.

[0024] Referring toFigures 1-4 , in an embodiment of the present utility model, a grounding protection device for electric power construction includes: a protective cover box 1 and a conductive wire 2. A fixing block 3 is fixedly connected to the upper surface of the protective cover box 1. A first limiting plate 4 is fixedly connected to the side surface of the fixing block 3. A first insulating pad 5 is fixedly connected to the inner surface of the first limiting plate 4. A first fixing plate 6 is fixedly connected to the upper surface of the protective cover box 1. A second fixing plate 7 is fixedly connected to the upper surface of the protective cover box 1. A pull rod 8 is slidably connected to the inner surface of the second fixing plate 7. A pull plate 9 is fixedly connected to the left end of the pull rod 8. The inner surface of the first fixing plate 6 is slidably connected to the pull rod 8. A second limiting plate 10 is fixedly connected to the right end of the pull rod 8. A second insulating pad 11 is fixedly connected to the inner surface of the second limiting plate 10. A fixing piece 12 is fixedly connected to the side surface of the pull rod 8. A spring 13 is fixedly connected to the left end of the fixing piece 12. The pull rod 8 passes through the inside of the spring 13. The left end of the spring 13 is fixedly connected to the second fixing plate 7. The conductive wire 2 is limited by the first limiting plate 4, the first insulating pad 5, the second limiting plate 10, and the second insulating pad 11. When it is necessary to fix the conductive wire 2, the pull plate 9 is pulled to drive the pull rod 8, the fixing piece 12, the second limiting plate 10, and the second insulating pad 11 to move. The movement of the fixing piece 12 drives the spring 13 to be compressed. The second limiting plate 10 and the first limiting plate 4 move away from each other. One end of the conductive wire 2 is passed through between the first limiting plate 4 and the second limiting plate 10 and fixed inside the protective cover box 1. The pull on the pull plate 9 is released, and the spring 13 rebounds to drive the fixing piece 12, the pull rod 8, the pull plate 9, the second limiting plate 10, and the second insulating pad 11 to move, so as to limit the conductive wire 2. This structure can limit conductive wires 2 of different sizes, and the flexibility and applicability of the device are strong. At the same time, the setting of the first insulating pad 5 and the second insulating pad 11 can further enhance the insulation performance between the conductive wire 2 and the limiting plate, prevent current leakage through the first limiting plate 4 and the second limiting plate 10 due to accidental contact, ensure the reliability and safety of the grounding system. At the same time, the insulating pad can play a buffering and isolating role, avoid direct contact between the conductive wire 2 and the limiting plate, reduce the friction and extrusion of the first limiting plate 4 and the second limiting plate 10 directly contacting the conductive wire 2, thereby prolonging the service life of the conductive wire 2 and ensuring its normal conductive and insulating functions.

[0025] A fixing frame 18 is fixedly connected to the upper surface of the protective cover box 1. The inner surface of the fixing frame 18 is fixedly connected to the first fixing plate 6. The inner surface of the fixing frame 18 is fixedly connected to the second fixing plate 7, which increases the stability of the structural connection. A conductive plate 19 is fixedly connected to the lower surface of the protective cover box 1. A mounting bolt 20 is threadedly connected to the inner surface of the conductive plate 19. The device is installed at a specified position through the conductive plate 19 and the mounting bolt 20.

[0026] The upper surface of the second limiting plate 10 is fixedly connected with a first soft pad 14, and the upper surface of the second insulating pad 11 is fixedly connected with the first soft pad 14. The upper surface of the first limiting plate 4 is fixedly connected with a second soft pad 15, and the upper surface of the first insulating pad 5 is fixedly connected with the second soft pad 15. By providing the first soft pad 14 and the second soft pad 15, it can prevent the harder upper ends of the first limiting plate 4 and the second limiting plate 10 from damaging the conducting wire 2. The lower surface of the second limiting plate 10 is fixedly connected with a third soft pad 16, and the lower surface of the second insulating pad 11 is fixedly connected with the third soft pad 16. The lower surface of the first limiting plate 4 is fixedly connected with a fourth soft pad 17, and the lower surface of the first insulating pad 5 is fixedly connected with the fourth soft pad 17. The third soft pad 16 and the fourth soft pad 17 provided play a protective role for the internal conducting wire 2.

[0027] Working principle: When it is necessary to fix the conducting wire 2, pull the pull plate 9 to drive the pull rod 8, the fixing piece 12, the second limiting plate 10 and the second insulating pad 11 to move. The movement of the fixing piece 12 drives the spring 13 to be compressed. The second limiting plate 10 and the first limiting plate 4 move away from each other. Pass the conducting wire 2 through and fix one end between the first limiting plate 4 and the second limiting plate 10 inside the protective cover box 1. Release the pull on the pull plate 9, and the spring 13 rebounds to drive the fixing piece 12, the pull rod 8, the pull plate 9, the second limiting plate 10 and the second insulating pad 11 to move, so as to limit the conducting wire 2 between the first limiting plate 4 and the second limiting plate 10. When the second limiting plate 10 and the second insulating pad 11 move, they can limit the conducting wire 2 of different sizes. The applicability of the device is strong. The device can quickly and conveniently limit and fix the conducting wire 2. During the process, there is no need to search for tools or rely on other tools to install and fix the conducting wire 2, which saves the time for fixing the conducting wire 2 and improves the installation efficiency of fixing the conducting wire 2. Moreover, it can quickly fix the conducting wire 2 of different sizes. The flexibility and applicability of the device are strong.
