Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a grounding resistance detection device. Background Technology

[0002] Grounding resistance is a key parameter for measuring the effectiveness of grounding in electrical equipment or systems. It represents the resistance encountered by current flowing from the grounding device into the earth. Ideally, the grounding resistance should be as low as possible to ensure that in the event of an electrical fault (such as a short circuit), the current can be quickly and safely conducted into the ground through the grounding system, thereby protecting the safety of people and equipment. Grounding resistance is used in communication base stations, wind turbine generators, solar photovoltaic arrays, substations, mining operations, and more.

[0003] Currently, not all existing grounding resistors are located in flat areas. However, grounding resistors must be in a horizontal position to be tested. If the position is tilted during the test, the test results of the instrument will be inaccurate.

[0004] Therefore, how to provide a grounding resistance detection device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a grounding resistance detection device to solve the problems mentioned in the background art.

A rack plate is fixedly connected to both sides of the inner wall of the fixed sleeve plate. A rotating gear is meshed with one of the rack plates on adjacent sides. A rotating handle is fixedly connected to the middle of the outer wall of the rotating gear. A fixed rod is fixedly connected to the middle of the rear side of the rotating gear. A movable plate is fixedly connected to the rear side of the fixed rod. A connector is fixedly connected to the bottom of the movable plate. Several fixed slots are formed on both sides of the outer wall of the fixed sleeve plate, and the fixed slots engage with the rotating rod.

[0007] As a preferred embodiment of this utility model: the outer wall of the fixed sleeve is slidably connected to a movable sleeve, and the outer wall of the movable sleeve is fixedly connected to a fixed block.

[0008] As a further preferred embodiment of this utility model: a brake wheel is fixedly connected to the bottom of the fixed block, and rotating levers are engaged on both sides of the outer wall of the movable sleeve.

[0012] As a further preferred embodiment of this utility model: several clamping telescopic plates are fixedly connected inside the fixed box, and a resistance detector body is provided on one side of the clamping telescopic plates.

[0013] The beneficial effects of this utility model are:

[0014] By rotating the handle, the rotating gear rotates clockwise, causing the movable plate to move downwards to the appropriate position. Then, the connector at the bottom of the movable plate is inserted into the ground. Next, the remaining movable plates are adjusted according to the flatness of the ground. The bubble level is used to check if it is level, ensuring that the main body of the resistance detector is in a horizontal position, making the detection of grounding resistance more accurate. When on a flat road section, the rotating rod can be pulled out from inside the movable sleeve, causing the movable sleeve to slide downwards from the outer wall of the fixed sleeve plate. When it slides to the bottom of the outer wall of the fixed sleeve plate, the rotating rod is inserted into the fixed slot inside the fixed sleeve plate. The fixed slot and adjustment components can be moved by the brake wheel at the bottom of the movable sleeve. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] refer to Figure 1As shown in Figures 1, 2, and 3, a grounding resistance detection device includes a fixed housing 1 and a fixed sleeve 6. A rack plate 10 is fixedly connected to both sides of the inner wall of the fixed sleeve 6. A rotating gear 11 is meshed with one of the rack plates 10 on the adjacent side. A rotating handle 9 is fixedly connected to the middle of the outer wall of the rotating gear 11. A fixed rod 12 is fixedly connected to the middle of the rear side of the rotating gear 11. A movable plate 4 is fixedly connected to the rear side of the fixed rod 12. A connector 13 is fixedly connected to the bottom of the movable plate 4. Several fixed slots 19 are formed on both sides of the outer wall of the fixed sleeve 6. The inside of the fixed slots 19 engages with the rotating rod 7. A movable sleeve 5 is slidably connected to the outer wall of the fixed sleeve 6. A fixed block 15 is fixedly connected, and a brake wheel 21 is fixedly connected to the bottom of the fixed block 15. Rotating rods 7 are snapped onto both sides of the outer wall of the movable sleeve 5. A fixed ring plate 8 is fixedly connected to the bottom of the fixed box 1. Several rotating shafts 14 are fixedly connected to the bottom of the fixed ring plate 8. A connecting block 3 is rotatably connected to the outer wall of the rotating shaft 14. The bottom of the connecting block 3 is fixedly connected to the fixed sleeve plate 6. A bubble level 20 is fixedly connected to the middle of the front side of the fixed box 1. A top cover 2 is hinged to the top of the fixed box 1. A cooling fan 16 is fixedly connected to the inner wall of the top cover 2. Several clamping telescopic plates 18 are fixedly connected inside the fixed box 1. A resistance detector body 17 is set on the side close to the clamping telescopic plates 18.

[0027] By rotating the handle 9, the rotating gear 11 is driven to rotate clockwise. The rotation of the rotating gear 11 causes the movable plate 4 to move downwards to the appropriate position. Then, the connector 13 at the bottom of the movable plate 4 is inserted into the ground. Next, the remaining movable plates 4 are adjusted according to the flatness of the ground. The bubble level 20 is used to observe whether it is in a horizontal state, so that the resistance detector body 17 can be in a horizontal position, making the detection of grounding resistance more accurate. The clamping telescopic plate 18 can clamp the resistance detector body 17 and make the resistance detector body 17 shake slightly, which can prevent the resistance detector body 17 from being damaged during transportation. The bubble level 20 can monitor whether the resistance detector body 17 is in a horizontal position.

[0028] Working principle:

[0029] First, open the top cover 2 of the fixed housing 1. Place the resistance detector body 17 in the middle of the clamping telescopic plate 18. The clamping telescopic plate 18 clamps the resistance detector body 17. Then, pull the fixed sleeve 6 outward to rotate it. Next, rotate the handle 9 to drive the rotating gear 11 to rotate clockwise. The rotation of the rotating gear 11 drives the movable plate 4 to move downward to the appropriate position. Then, insert the connector 13 at the bottom of the movable plate 4 into the ground. Then, adjust the remaining movable plates according to the flatness of the ground. 4. Adjust the bubble level 20 to ensure it is level, so that the main body 17 of the resistance detector is in a horizontal position, making the detection of grounding resistance more accurate. When on a level road section, first pull the rotating rod 7 out of the movable sleeve 5 to drive the movable sleeve 5 to slide down from the outer wall of the fixed sleeve 6. When it slides to the bottom of the outer wall of the fixed sleeve 6, insert the rotating rod 7 into the fixed slot 19 inside the fixed sleeve 6. The fixed slot 19 and the adjustment component can be moved by the brake wheel 21 at the bottom of the movable sleeve 5.
