Description

Technical Field

[0001] The utility model relates to a grounding device, in particular to a grounding device for power distribution. Background Art

[0002] With the advancement of the modernization era, the rapid development of the power system and the proposal of smart grids, there are more stringent requirements and standards for the reliability of equipment and the safety of operation. Among them, electrical testing and grounding are necessary operations for line power outage maintenance, and are principled operations related to personal and equipment safety. When hanging the temporary grounding wire of the distribution network, first use a tester to test the electricity before connecting it. There is a time difference. When reverse power supply occurs instantly, the risk of electric shock cannot be avoided. In addition, whether the "wire end" is connected reliably cannot be quantified to determine its qualification, and real-time monitoring cannot be achieved.

[0003] The grounding device is composed of a grounding body (round steel, angle steel, flat steel, steel pipe, etc.) buried in the soil and a grounding wire for connection. It is used to connect the electrical system to the earth, thereby protecting the safe and stable operation of the power distribution network. However, the existing grounding devices of the power distribution network usually adopt a method of directly connecting the grounding wire and the grounding electrode, and using a staggered lock structure to achieve the connection. This type of connection structure is single, the protection work is not effective, and there is a lack of insurance protection, which leads to the repair personnel often being unable to complete the repair work safely, posing a safety hazard.

[0004] Therefore, the utility model provides a grounding device for electric power distribution. Utility Model Content

DETAILED DESCRIPTION

[0022] like Figure 2 and Figure 5 As shown, the clamping mechanism includes a clamping block 17, a fixing rod 18, a roller 19 and a spring 20. Two left-right symmetrical clamping blocks 17 are slidably connected to the upper part of the annular hook 1. A fixing rod 18 is fixedly connected to the middle part of each clamping block 17. The fixing rod 18 is rotatably connected to the roller 19, and a spring 20 is welded between each clamping block 17 and the annular hook 1.

[0023] like Figure 2 and Figure 4 As shown, the fixing mechanism includes a first gear 10, a second gear 11, a fixed plate 12, a block 13, a torsion spring 14 and a limit block 16. The first gear 10 is welded to the rear side of the first rotating rod 9, and two fixed plates 12 are welded to the front side of the protective cover 15. The block 13 is rotatably connected between the two fixed plates 12. The torsion spring 14 is fixedly connected between the block 13 and the fixed plate 12. The two torsion springs 14 are symmetrically distributed on both sides of the block 13 in the front and back, and the second gear 11 is fixedly connected to the rear side of the upper part of the block 13. The second gear 11 is meshed with the first gear 10. The upper part of the annular hook 1 is fixedly connected to the limit block 16. The limit block 16 is annular block-shaped, and the block 13 contacts the limit block 16 when it rotates.

[0024] like Figure 2As shown, it also includes a voltage detector 21. The voltage detector 21 is fixedly connected to the upper inner part of the annular hook 1. The voltage detector 21 is electrically connected to the controller 501. An electric wire connected to the ground wire 101 is fixedly connected to the right side of the right clamping block 17, and the electric wire is also in contact with the roller 19. The electric wire on the right side of the right clamping block 17 is in sliding contact with the voltage detector 21.

[0025] When we need to install the grounding wire 101 for grounding, we can use this device to work. This device can be hung on a cable or a place where a grounding device needs to be installed. The annular hook 1 needs to be hung stably. A plastic handle 102 is provided at the bottom of this device to prevent the risk of electric shock caused by contact between a person and the device. Before hanging, the rotation angle of the clamping block 13 is open, so that it is easy to clamp it into the clamping mechanism. After the object enters the middle of the clamping block 17 from the bayonet, the grounding wire 101 is then pulled, so that the grounding wire 101 is changed from the contracted state of the winding wheel 8 to the stretched and tight state. Due to the pulling and tightening of the grounding wire 101, the winding wheel 8 will rotate to drive the first rotating rod 9 to rotate, and A first gear 10 is fixedly connected to the outside of the first rotating rod 9, so the first gear 10 will be driven to rotate. On the basis of the meshing of the first gear 10 and the second gear 11, the second gear 11 will rotate clockwise. Since the second gear 11 is fixedly connected to the clamping block 13, the clamping block 13 will be driven to rotate. The clamping block 13 rotates until it contacts the limit block 16, so that the clamped grounding wire 101 or the clamped object can be sealed to prevent it from slipping. When the cable is closed by the clamping block 13, the cable will pass through the roller 19 in the middle of the clamping block 17, thereby being drawn into the two clamping blocks 17, so that the cable is squeezed by the two clamping blocks 17, thereby clamping it to prevent the cable from slipping.

[0026] After the cable is clamped, a protection box 2 is fixedly connected to the bottom of the device, and a grounding cone 3 is arranged inside the protection box 2. Since the front end of the grounding cone 3 is a sharp cone, it is easier to insert into the ground. When inserted into the ground, the grounding wire 101 is appropriately stretched by the upper wire-reeling wheel 4, so that the grounding cone 3 has enough extension space. After the grounding cone 3 is buried in the ground, the current can be diverted to the underground in case of an emergency. When the cable has been hung for a long time, the maintenance personnel will conduct regular inspections on it, so it is necessary to use this device for operation. During the inspection, the real-time voltage can be checked through the upper voltage detector 21 of the device. After it is normal, the grounding device can be inspected. If there is voltage passing through the voltage detector 21, it means that the cable is energized, and the voltage detector 21 transmits an electrical signal to the controller 501, and the controller 501 controls the current alarm 5 to sound an alarm, thereby warning the operator to evacuate in time to avoid electric shock.

[0027] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above-mentioned embodiments, but should be determined not only by the appended claims, but also by the equivalents of the appended claims.
