Description

Technical Field

[0001] The utility model belongs to the technical field of safety inspection devices, and particularly relates to a grounding safety inspection device. Background Art

[0002] In high-voltage lightning strike test equipment, experimental samples need to be disassembled and installed multiple times. Before installation, the voltage must be discharged by touching the charged component with a grounding rod connected to the grounding wire, so as to prevent experimental personnel from being injured by high voltage during the operation.

[0003] Since the grounding point of the grounding device is far from the power consumption point of the equipment, flat steel is often used for long-distance connection. In this case, the grounding is often disconnected due to unknowing construction or corrosion of the flat steel. Once this happens, when high-voltage experimental personnel discharge the high-voltage equipment with a grounding rod without knowing it, the high voltage of the equipment cannot be discharged. Once the experimental personnel touch the charged equipment, it will cause serious personal injury or even endanger life. Content of the Utility Model

[0049] Specific embodiments are given below.

[0050] As Figure 1 and Figure 2 shown, a grounding safety inspection device includes a wall 1, and a fixing plate 2 is fixedly assembled on the outer wall of the wall 1;

[0051] A motor 8 is fixedly assembled on the top of the fixing plate 2. A transmission wheel 9 is fixedly sleeved on the output shaft of the motor 8. A transmission belt 10 is rollingly connected in the middle of the transmission wheel 9. A lead screw 11 is fixedly assembled at the bottom of the transmission wheel 9.

An inspection box 14 is fixedly assembled on the top of the lifting seat 13;

[0052] A light / sound warning device 15 is provided on the top of the inspection box 14. A grounding inspection point 16 is fixedly assembled on the outer wall of the inspection box 14. A straight pipe 18 is fixedly assembled at one end of the inspection box 14 away from the grounding inspection point 16. A live wire 19 is sleeved inside the straight pipe 18;

[0053] Chute 20 is provided on both the wall 1 and the fixing plate 2. A limiting groove 21 is provided on the outer wall of the fixing plate 2. An insulating sleeve 3 is provided on the left side of the fixing plate 2. An adjusting groove 4 is provided on the outer wall of the insulating sleeve 3. An insulating adjusting rod 7 is slidably sleeved inside the fixing plate 2. A threaded rod 5 is fixedly assembled on the outer wall of the insulating adjusting rod 7. A fastening nut 6 is threadedly connected to the outer wall of the threaded rod 5. A grounding rod 17 is fixedly assembled at the top of the insulating adjusting rod 7. A grounding wire 22 is fixedly connected to the outer wall of the grounding rod 17;

[0054] By setting the structures of the wall 1, the fixing plate 2, the insulating sleeve 3, the inspection box 14, the light / sound warning device 15, the grounding inspection point 16, and the grounding rod 17, during the operation of the device, the user can determine whether there is a fault in the grounding wire 22 by observing whether the fixing plate 2 lights up, so as to achieve the effect of detecting the grounding wire 22 without using professional instruments. It has the characteristics of simple structure, low manufacturing cost, and intuitive signal, thereby improving the practicability of the device.

[0055] As Figure 1 and Figure 2As shown, the inner wall of the limit groove 21 is slidably connected to the outer wall of the slider 12, and the outer wall of the fixed plate 2 is slidably connected to the outer wall of the lifting seat 13. Through the provided structure of the slider 12 and the limit groove 21, when the user uses the device to detect the grounding wire 22, the height of the lifting seat 13 can be changed by the operation of the motor 8, so that users of different heights can operate the device;

[0056] The cooperation between the limiting groove 21 and the sliding block 12 can ensure that the lifting seat 13 does not have position deviation or even shaking during the lifting process, thereby improving the stability of the lifting seat 13 during the lifting process.

[0057] like Figure 3 and Figure 5 As shown, a conductive rod is fixedly installed on the top of the inspection box 14, and the light / sound alarm 15 is electrically connected to the inspection box 14 through the conductive rod. The inspection box 14 is connected to the ground through the grounding checkpoint 16 and the grounding rod 17. Through the set conductive rod structure, when the user has assembled the device, the light / sound alarm 15 can be directly turned on due to the connection of the circuit through the overlap of the grounding rod 17 and the grounding checkpoint 16, thereby achieving the effect of quickly docking the device for detection operations and ensuring the normal operation of the device.

[0058] like Figure 1 and Figure 2 As shown, there are two transmission wheels 9, which are connected by a transmission belt 10. By setting up the two transmission wheels 9 and the transmission belt 10 structure, the device uses a single motor 8 to drive one transmission wheel 9 to rotate during operation, and cooperates with the transmission effect of the transmission belt 10 to make the two transmission wheels 9 rotate synchronously, thereby ensuring that the lifting seat 13 can stably perform lifting operations, thereby improving the smoothness of the device during operation.

[0059] like Figure 1 and Figure 2 As shown, the inspection box 14 is higher than the human body can touch during operation. Under the premise of ensuring that the grounding inspection point 16 can contact the grounding rod 17, the inspection box 14, the grounding inspection point 16 and the grounding rod 17 are all in a position that the human body cannot touch, thereby avoiding the accidental electric shock of the human body;

[0060] At the same time, the grounding check point is a spherical or downward-inclined metal body (for example, 30° downward) to prevent the grounding rod from being hung on it and causing long-term live wire grounding.

[0061] like Figure 1 and Figure 5As shown, the outer wall of the threaded rod 5 is slidably connected to the inner wall of the adjustment groove 4, and the insulating adjustment rod 7 is fixedly connected to the insulating sleeve 3 through the tight fit of the fastening nut 6 with the insulating sleeve 3; through the structures of the adjustment groove 4, the threaded rod 5, the fastening nut 6, and the insulating adjustment rod 7; when using this device to detect the grounding wire 22, the user can loosen the fastening nut 6 to make the insulating adjustment rod 7 and the insulating sleeve 3 in a movable connection state, so as to facilitate the user to adjust the height of the insulating adjustment rod 7;

[0062] Cooperate with the lifting operation of the lifting seat 13 to make the grounding inspection point 16 contact the grounding rod 17. After adjustment, the device can continue to detect the grounding wire 22.

[0063] After installing the inspection device on the wall according to the present utility model, the user can adjust the lengths of the insulating adjustment rod 7 and the insulating sleeve 3 according to their own height requirements, and then tighten the fastening nut 6 to make the insulating adjustment rod 7 and the insulating sleeve 3 in a fixed connection state; then, through the operation of the motor 8, the two lead screws 11 rotate synchronously to make the lifting seat 13 rise, so that the grounding inspection point 16 and the grounding rod 17 touch to conduct an inspection;

[0064] When the insulating adjustment rod 7 touches the grounding rod 17, the light / sound warning device 15 is equivalent to being connected between the live wire 19 and the grounding wire 22. If the grounding wire device has no faults, the light / sound warning device 15 will light up, indicating that the grounding device is normal; if there are faults in the grounding device, the light / sound warning device 15 will not work, prompting that the grounding has faults and needs to be checked.

[0065] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
