Description

Technical Field

[0001] This utility model belongs to the field of grounding device technology, specifically, it relates to a grounding protection device for electrical equipment. Background Technology

[0002] Grounding is an electrical safety measure that refers to connecting the neutral point of a power system and electrical installation, the exposed conductive parts of electrical equipment, and the external conductive parts of the equipment to the earth via a conductor.

[0003] During operation, electrical equipment is typically connected to a grounding protection device to ensure personnel safety and normal equipment operation. Good grounding protection can conduct leakage current generated by the electrical equipment in the event of a fault into the earth, preventing electric shock and equipment damage. However, the grounding wire used to connect to the electrical equipment and the grounding pin is usually left with a sufficiently long length. After the grounding pin and grounding wire are installed, the excess length of grounding wire is often misplaced. If the misplaced grounding wires become tangled together, they can easily be damaged during the process of workers untangling them.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

A grounding wire is connected to the device body, and the grounding pin is connected to the grounding wire. A protective shell is fixedly installed on one side of the device body, and a sealing plate is installed on one side of the protective shell by bolts. The grounding wire passes through the protective shell and extends to the outer bottom of the protective shell. A wire feeding seat is fixedly installed on the inner wall of the bottom of the protective shell, and a first wire groove is formed on the wire feeding seat. A clamping plate is slidably installed on the inner side of the protective shell, and a second wire groove is formed at the bottom of the clamping plate. The first wire groove and the second wire groove have the same specifications and correspond to each other.

[0007] In a preferred embodiment of this utility model, the bottom of the protective shell is provided with a through hole, and a cable sleeve is installed on the inner wall of the through hole.

[0008] In a preferred embodiment of this utility model, the grounding wire is located inside the cable sheath, and the bottom end of the cable sheath is connected to the top end of the grounding pin.

[0011] In a preferred embodiment of this utility model, the bottom end of the threaded rod is rotatably connected to the top outer wall of the pressure plate, and a knob is installed at the top end of the threaded rod.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This utility model, when the equipment body generates leakage current in the event of a fault, can conduct the leakage current generated by the equipment body to the ground through the grounding pin and grounding wire, so as to avoid electric shock to personnel and damage to equipment.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0022] like Figs. 1 to 4 As shown

[0023] An electrical equipment grounding protection device includes an equipment body 1 and a grounding pin 2. A grounding wire 3 is connected to the equipment body 1, and the grounding pin 2 is connected to the grounding wire 3. The grounding pin 2 is inserted into the ground for grounding. When the equipment body 1 generates leakage current in the event of a fault, the leakage current generated by the equipment body 1 can be introduced into the ground through the grounding pin 2 and the grounding wire 3, preventing electric shock to personnel and damage to equipment. A protective shell 4 has a through hole at the bottom, and a cable sleeve 5 is installed on the inner wall of the through hole. The grounding wire 3 is located inside the cable sleeve 5, and the bottom end of the cable sleeve 5 is connected to the top end of the grounding pin 2. A protective shell 4 is fixedly installed on one side of the equipment body 1. The grounding wire 3 passes through the protective shell 4 and extends to the outer side of the bottom of the protective shell 4. A wire release seat 6 is fixedly installed on the inner wall of the bottom of the protective shell 4. A first wire groove 7 is opened on the wire release seat 6. After the grounding pin 2 is inserted into the ground, the operator arranges the excess length of the grounding wire 3 and places it in the first wire groove 7. A pressure plate 8 is slidably installed on the inner side of the protective shell 4, and a second wire groove 1 is opened at the bottom of the pressure plate 8. 2. The first groove 7 and the second groove 12 have the same specifications and correspond to each other. Multiple movable grooves 13 are provided on the inner wall of the protective shell 4. Multiple guide blocks 14 are fixedly connected to the outer wall of the pressure plate 8. The guide blocks 14 are slidably connected to the inner wall of the movable grooves 13. An installation hole is provided at the top of the protective shell 4, and a threaded sleeve 10 is fixedly installed on the inner wall of the installation hole. A threaded rod 9 is screwed onto the inner wall of the threaded sleeve 10. The bottom end of the threaded rod 9 is rotatably connected to the top outer wall of the pressure plate 8. A knob 11 is installed at the end. After the grounding wire 3 is placed in the first wire groove 7, the threaded rod 9 is rotated by the knob 11. In conjunction with the movable groove 13 and the guide block 14, the threaded rod 9 drives the clamping plate 8 to move downward until the bottom of the clamping plate 8 contacts the top of the wire release seat 6. At the same time, the top of the grounding wire 3 contacts the inner wall of the second wire groove 12. This can realize the function of storing and limiting the grounding wire 3, making it easy to organize and store the grounding wire 3 in the protective shell 4, and preventing the excess length of the grounding wire 3 from getting tangled together.

[0024] In a specific embodiment, a sealing plate 15 is bolted to one side of the protective housing 4. When the grounding wire 3 inside the protective housing 4 is being organized, the sealing plate 15 is removed from the protective housing 4. After the grounding wire 3 is stored, the sealing plate 15 is bolted back onto the protective housing 4 to achieve a sealing effect on the protective housing 4. The protective housing 4, cable sheath 5, cable holder 6, clamping plate 8, guide block 14 and sealing plate 15 are all made of insulating material.

[0025] The implementation principle of the electrical equipment grounding protection device in this embodiment is as follows: In specific use, the grounding pin 2 is inserted into the ground for grounding. After the grounding pin 2 is inserted into the ground, the sealing plate 15 is opened. After the sealing plate 15 is opened, the worker arranges the excess length of the grounding wire 3 and places it in the first wire groove 7. After placement, the threaded rod 9 is rotated by the knob 11. With the cooperation of the movable groove 13 and the guide block 14, the threaded rod 9 drives the pressing plate 8 to move downward until the bottom of the pressing plate 8 contacts the top of the wire release seat 6. At the same time, the grounding wire 3... The top contacts the inner wall of the second wire groove 12, thereby enabling the grounding wire 3 to be stored and limited, making it easy to organize and store the grounding wire 3 inside the protective shell 4, and preventing excess length of the grounding wire 3 from getting tangled together. After the grounding wire 3 is stored, the sealing plate 15 is installed on the protective shell 4 with bolts to achieve the sealing effect of the protective shell 4. When the equipment body 1 generates leakage current in the event of a fault, the grounding pin 2 and the grounding wire 3 can conduct the leakage current generated by the equipment body 1 to the ground, preventing electric shock to personnel and damage to equipment.
