Description

Technical Field

[0002] Grounding resistance is the resistance encountered by current flowing from the grounding device into the earth and then flowing through the earth to another grounding body or spreading to a distant place. The lightning protection grounding device of a building is one of the most important links in its lightning protection project. Regardless of direct lightning protection, lightning surge intrusion protection or lightning electromagnetic pulse protection, the lightning current is ultimately introduced into the earth through the grounding device. The most direct standard for measuring the grounding effect of a building's lightning protection grounding device is the size of the grounding resistance. Therefore, the actual measurement of the grounding resistance is an important means to verify the design and construction of the grounding device.

[0031] The cleaning mechanism 8 is slidably connected to the front end of the storage box 1 , and is used for cleaning the outside of the connecting line 5 .

[0032] First, the rear end of the top of the storage box 1 is rotatably connected to the box cover 101, the front of the box cover 101 is fixedly connected to the storage box 1 through a lock 102, and the top of the box cover 101 is fixedly connected to a handle 103. When the storage box 1 is in use, the box cover 101 is closed by the lock 102, and the storage box 1 is lifted by the handle 103 to facilitate carrying the detector body 2, the winding rack 3 and the probe 6.

[0033] Furthermore, a first placement slot 104 is provided at the right end inside the storage box 1, and the detector body 2 is placed on the inner side of the first placement slot 104; three groups of second placement slots 105 are provided on the right side of the storage box 1, and three groups of winding racks 3 are placed on the inner sides of the three groups of second placement slots 105; a third placement slot 106 is provided in the middle of the storage box 1, and two groups of probes 6 are staggeredly placed on the inner sides of the third placement slot 106; a partition 107 is fixedly connected to the inner side of the third placement slot 106 and located in the middle of the two groups of probes 6; when the storage box 1 is closed, the detector body 2 is located in the first placement slot 104 for protection, and the winding rack 3 and the probe 6 are respectively located on the inner sides of the second placement slot 105 and the third placement slot 106 for protection.

[0034] Then, both ends of the bottom of the three groups of winding racks 3 are covered with anti-skid sleeves 301, the right ends of the front faces of the three groups of winding racks 3 are fixedly connected with protective tubes 302, one end of the connecting line 5 is fixedly connected with a clamp 303, the clamp 303 extends to the inner side of the protective tube 302, and the other end of the connecting line 5 is fixedly connected with a connector 304. When performing the building lightning protection grounding resistance test, first reach the test point and take out the detector body 2 from the inner side of the first placement slot 104 and place it flat on the ground, then take out a group of winding racks 3 and place them flat on the ground, and use the anti-skid sleeve 301 to prevent the winding of the wire when winding and releasing the wire. The frame 3 moves, and one end with the clamp 303 is clamped on the grounding electrode. Then the winding drum 4 is rotated to release the connecting wire 5, and one end with the connector 304 is connected to the detector body 2. Then two groups of probes 6 are inserted into the ground surface along a straight line at a distance of twenty meters and forty meters from the detector body 2 respectively. Then the other two groups of winding frames 3 are taken out from the inside of the storage box 1, and the end of the connecting wire 5 inside the winding frame 3 with the clamp 303 is clamped on the probe 6, and the end with the connector 304 is connected to the detector body 2. The grounding resistance value of the grounding electrode can be obtained by observing the value on the detector body 2.

[0035] Furthermore, the backs of the three groups of winding drums 4 are fixedly connected with a crank handle 401, and the three groups of winding drums 4 are rotatably connected to the winding frame 3 through the rotating shaft 402. A locking column is threadedly connected at a position on the front of the winding frame 3 corresponding to the rotating shaft 402, and the top of the locking column is against the outside of the rotating shaft 402, and the bottom of the locking column is fixedly connected with a knob 403. After the inspection is completed, the crank handle 401 is held to rotate the winding drum 4 to reel in the wires, and the wires are reeled and stored separately through multiple groups of winding frames 3, thereby avoiding the problem of entanglement of multiple connecting wires 5. After the connecting wires 5 are reeled in, the clamp 303 of the connecting wire 5 is extended into the protective tube 302 for protection, and then the knob 403 is tightened up and down so that the locking column is against the outside of the rotating shaft 402 to fix the rotating shaft 402, thereby preventing the connecting wires 5 from spreading out when stored.

Before using the probe 6 each time, first observe whether the outer side of the probe 6 is oxidized. If the probe 6 is oxidized, pull the grinding frame 7 out of the storage box 1, and then grind the probe 6 on the grinding sandpaper 702 on the inner side of the arc-shaped support plate 701 to grind off the oxide layer on the surface of the probe 6 to ensure the use effect of the probe 6.

[0037] Finally, the cleaning mechanism 8 includes a first connecting frame 801 slidably connected to the front end of the storage box 1, the inner side of the first connecting frame 801 is rotatably connected to the first cleaning roller 802 and the second cleaning roller 803, the front side of the first connecting frame 801 is rotatably connected to the threaded rod 804, the front end of the second cleaning roller 803 is threadedly connected to the threaded rod 804 through a connecting sleeve 805, and the front end of the second cleaning roller 803 is rotatably connected to the connecting sleeve 805, the front end of the storage box 1 and the left side of the first connecting frame 801 is slidably connected to the second connecting frame 806, the top of the second connecting frame 806 is fixedly connected to a plurality of guide sleeves 807, when the connecting line 5 is wound up, the first connecting frame 801 and the second connecting frame 806 are first connected. The second connecting frame 806 is pulled out from the interior of the storage box 1, and then the threaded rod 804 is rotated to drive the connecting sleeve 805 to move upward, thereby moving the second cleaning roller 803 upward, so that the connecting line 5 can be placed between the first cleaning roller 802 and the second cleaning roller 803. After the connecting line 5 is placed, the second cleaning roller 803 is lowered to clamp the connecting line 5, and then the rear end of the connecting line 5 is placed into the inner side of the guide sleeve 807 to prevent it from being entangled during winding, and then the connecting line 5 is wound. During the winding process, if there is sludge on the outside of the connecting line 5, it can be squeezed out when passing through the first cleaning roller 802 and the second cleaning roller 803, thereby avoiding the sludge from being wound together, thereby ensuring the cleanliness of the storage box 1.

[0038] In this embodiment, the implementation scenario is specifically as follows: when the storage box 1 is used, the box cover 101 is closed by the lock buckle 102, and the storage box 1 is lifted by the handle 103 to facilitate the carrying of the detector body 2, the winding rack 3 and the probe 6. When performing the building lightning protection grounding resistance test, the detector body 2 is first taken out from the inner side of the first placement groove 104 after reaching the test point and placed flat on the ground. Then, a set of winding racks 3 are taken out and placed flat on the ground. The anti-slip cover 301 is used to prevent the winding rack 3 from slipping when winding and releasing the wire. Move, clamp the end with the clamp 303 to the ground electrode, then rotate the winding drum 4 to release the connecting wire 5, and connect the end with the connector 304 to the detector body 2, and then insert the two sets of probes 6 into the ground surface along a straight line at a distance of 20 meters and 40 meters from the detector body 2, and then take out the other two sets of winding racks 3 from the inside of the storage box 1, clamp the probe 6 with the end of the connecting wire 5 with the clamp 303 inside the winding rack 3, and connect the end with the connector 304 to the detector body 2, and observe the detector. The value on the main body 2 can be used to obtain the grounding resistance value of the grounding electrode. When the connecting wire 5 is rolled up, the first connecting frame 801 and the second connecting frame 806 are first pulled out from the inside of the storage box 1, and then the threaded rod 804 is rotated to drive the connecting sleeve 805 to move upward, thereby moving the second cleaning roller 803 upward, so that the connecting wire 5 can be placed between the first cleaning roller 802 and the second cleaning roller 803. After the connecting wire 5 is placed in, the second cleaning roller 803 is lowered to clamp the connecting wire 5, and then the rear end of the connecting wire 5 is placed into the inner side of the guide sleeve 807 to prevent it from being entangled after rolling up, and then the connecting wire 5 is rolled up. If there is sludge on the outside of the connecting wire 5 during the rolling process, it can be squeezed out when passing through the first cleaning roller 802 and the second cleaning roller 803, thereby avoiding the sludge from being rolled up together. The entire operation process is simple and convenient. Compared with the existing building lightning protection grounding resistance detection device, the utility model can improve the overall convenience and cleanliness of the building lightning protection grounding resistance detection device through design.
