The outer surface of the winding tube 303 is fixedly connected to the outer surface of the housing of the grounding wire 203. One end of the transmission shaft 302 is fixedly installed with a storage cover 304. The storage cover 304 is in movable rotational contact with the inner wall of the outer shell 103 of the second maintenance box. A limiting tooth 305 is installed on the outer surface of the transmission shaft 302. A plurality of limiting teeth 305 are arranged in an annular array on the outer surface of the outer plate of the transmission shaft 302. The limiting tooth 305 is in movable contact with the locking tooth 402. The connecting wire 406 is rotatably connected to the limiting plate 401. A return spring 405 is installed on the outer surface of the control rod 404. The bottom surface of the return spring 405 is in contact with the bottom surface of the inner wall of the adjustment hole 403. The top surface of the return spring 405 is in contact with the bottom surface of the control rod 404.
[0036] In the embodiment of the present invention, when the load in the distribution box disappears, at this time, the grounding wire 203 continues to be used to provide the grounding function for the distribution box to ensure construction and installation. After the maintenance is completed, at this time, hold the storage cover 304 on one side surface of the outer shell 103 of the second maintenance box and drive it to rotate. When the storage cover 304 rotates, it will drive the transmission shaft 302 to rotate on the inner wall of the positioning shaft. And a winding tube 303 is installed on the outer surface of the transmission shaft 302. At this time, the rotating winding tube 303 will wind the grounding wire 203 around its outer surface again through rotation to achieve the storage function. After stopping the winding, at this time, the limiting plate 401 will rotate, so that the locking tooth 402 provided on its bottom surface is inserted between the limiting teeth 305, so as to realize the storage of the grounding wire 203.
[0037] Specific usage process: When the power distribution cabinet maintenance device is needed, open the cabinet door of the distribution box at this time, and hang it on the top surface of the maintenance box door through the handle 101 installed on one side surface of the maintenance box. When the maintenance box is hung on the surface of the maintenance box door, unfold the entire maintenance box at this time, so that multiple first maintenance box housings 1 and second maintenance box housings 103 are arranged vertically on one side surface of the maintenance box door. When the unfolding is completed, connect the electric pen 201 and the multimeter 2 to each other at this time. When the two are connected, detect the electrical equipment inside the power distribution cabinet through the electric pen 201 at this time. When there are problems in the power distribution cabinet that need to be repaired, cut off the power supply of the distribution box at this time, and at the same time, by moving the electric pen 201, the connection between the two electric pens 201 and the multimeter 2 is no longer there, and take out the fixed clip 204 from the inner wall of the card slot 105, open it by pinching the fixed clip 204 and clamp it inside the distribution box. When the fixed clip 204 is clamped, push the connection plug 202 to move inside the positioning plate 106 at this time. The pushed connection plug 202 will extend and slide inside the inner wall of the positioning plate 106, and finally insert into the multimeter 2, so that the connection plug 202 ground wire 203 is connected to the multimeter 2. When the connection is completed, press the control rod 404 at this time. When the control rod 404 is under pressure, it will move downward inside the adjustment hole 403, so as to squeeze the reset spring 405 on its bottom surface. And when the control rod 404 moves downward, its end will squeeze the limit plate 401, so that the limit plate 401 rotates inside the setting groove 4. There are teeth 402 on the bottom surface of the limit plate 401. When the limit plate 401 rotates, the teeth 402 will no longer contact the limiting teeth 305 installed on the outer surface of the transmission shaft 302 at this time. At this time, the transmission shaft 302 can rotate because it loses the limit of the teeth 402. At this time, the maintenance personnel can hold the grounding weight installed at the end of the wire and pull it. When the grounding weight block is pulled, the winding tube 303 will rotate inside the storage groove 3. The ground wire 203 wound around its outer surface is released from the storage groove 3 through the rotation of the winding tube 303, and finally the grounding weight cone 205 installed at the end of the ground wire 203 contacts the ground. At this time, insert the grounding weight cone 205 in contact with the ground into the relatively loose soft soil, so as to realize the grounding function. Since there will still be a certain amount of charge residue inside the distribution box when the power is cut off, and at this time the ground wire 203 is connected to the distribution box and the other end contacts the ground, so the ground wire 203 in contact with the ground will quickly release the residual charge in the distribution box to the ground through the ground wire 203 at this time, so as to realize the grounding function when repairing the distribution box. And the ground wire 203 is in contact with the multimeter 2. During the discharging process, the remaining load residue in the distribution box can be judged by observing the screen of the multimeter 2.
[0038] When the load in the distribution box disappears, the grounding wire 203 continues to be used to provide the grounding function for the distribution box to ensure construction and installation. After the maintenance is completed, pinch the storage rotating cover 304 on one side surface of the second inspection box housing 103 and drive it to rotate. When the storage rotating cover 304 rotates, it will drive the transmission shaft 302 to rotate on the inner wall of the positioning shaft. A winding tube 303 is installed on the outer surface of the transmission shaft 302. At this time, the rotating winding tube 303 will rewind the grounding wire 203 on its outer surface through rotation and winding to achieve the storage function. After stopping the winding, the limiting plate 401 will rotate, so that the teeth 402 provided on the bottom surface thereof are inserted between the limiting teeth 305, thereby realizing the storage of the grounding wire 203.
[0039] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
