[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting the first auxiliary mechanism, when the manual lock on the box door is damaged and a fault occurs inside the power distribution equipment, the box door can be quickly opened, that is, to prevent the fault from spreading continuously and even expanding to the entire power distribution system, thus causing a large-scale power outage, which in turn affects production and living order and causes economic losses. This not only improves the use efficiency of the power distribution equipment. When a sudden fault occurs inside the power distribution equipment, and the manual lock on the box door is also damaged and the box door needs to be quickly opened, first, the cooperation of the monitoring equipment, antenna, and controller in the monitoring room can be used to start the electric push rod. Subsequently, the cooperation of the started electric push rod, two chutes, and two sliders can be used to make the two clamping blocks move towards each other until the two sliders can no longer move.

When the power distribution equipment needs to be used, first connect the external power supply wire head, power distribution equipment, and load equipment together according to the circuit installation criteria. Then, manually close the main power switch and the molded case circuit breaker. At the same time, use the controller to close all the miniature circuit breakers to use the power distribution equipment. When the power distribution equipment starts to be used, first, the cooperation of the main power switch, the first wire, the second wire, and the molded case circuit breaker can be used to deliver the externally transmitted electricity to each miniature circuit breaker. Subsequently, the corresponding wires can be used to deliver the electricity to each load equipment.

At the same time, through the cooperation of the controller and the antenna, the detected current data will be wirelessly transmitted to the monitoring equipment in the monitoring room for the staff in the monitoring room to view.

[0017] 3. By providing the second auxiliary mechanism, the present invention can reduce the grounding resistance of the grounding mechanism and improve its stability at the same time. When it is necessary to reduce the grounding resistance, first, a metal frame composed of a circular tube, two inclined plates, and a rectangular grid plate with a sealing ring is sleeved on the grounding electrode. Subsequently, by using tools and the cooperation of two auxiliary blocks and fixing bolts, the metal frame can be stably fixed on the grounding electrode, that is, by increasing the contact area between the grounding electrode and the soil, the grounding resistance can be reduced, and the stability of the grounding mechanism during use can also be improved.

[0018] 4. By providing the grounding mechanism, the present invention can conduct electricity into the ground when electric leakage occurs inside the distribution box, that is, to prevent people from touching the distribution box and causing electric shock accidents. When it is necessary to use the grounding mechanism, first, by using the cooperation of a U-shaped clip, a hand-tightening screw, a clamping block, and a conductive block, the grounding mechanism can be connected to the power distribution equipment. Subsequently, by using the cooperation of an auxiliary ring and a sharp cone, the grounding electrode can be inserted into the soil on the ground. When electric leakage occurs inside the power distribution equipment, at this time, by directly using the cooperation of the conductive block, the conductive sheet, the grounding wire, and the grounding electrode, the electricity on the distribution box can be conducted into the ground.

The grounding mechanism 3 includes a conductive sheet 301. A second auxiliary mechanism 4 is provided on the grounding mechanism 3. The second auxiliary mechanism 4 includes a sharp cone 401, a round tube 402, and a cylindrical groove 405. A rectangular grid plate 403 is fixed to the outer wall of the round tube 402. Two symmetrically arranged inclined plates 404 are fixed to the outer wall of the round tube 402. The bottoms of the two inclined plates 404 are both fixed to the top of the rectangular grid plate 403. Two sliding holes 406 are opened at a position near the top of the inner wall of the cylindrical groove 405. A clamping strip 407 is slidably connected to the inside of each sliding hole 406. The opposite ends of the two clamping strips 407 are both slidably embedded in the inner wall of the round tube 402. The bottom of one clamping strip 407 is in contact with the top of the other clamping strip 407. An auxiliary block 408 is fixed to the surface of each clamping strip 407. Both auxiliary blocks 408 are located inside the cylindrical groove 405. A fixing bolt 409 passes through the bottom of the other clamping strip 407 movably. The threaded end of the fixing bolt 409 passes through the bottom of one clamping strip 407 movably. The threaded end of the fixing bolt 409 is threadedly connected to the top of the inner wall of the cylindrical groove 405. A drying packet 410 is arranged inside the cylindrical groove 405. Two symmetrically arranged mounting grooves 411 are opened on the inner wall of the round tube 402. A sealing ring 412 is arranged inside each mounting groove 411. A U-shaped clamp 302 is fixed to the surface of the conductive sheet 301. A hand-tightening screw 303 passes through the top of the U-shaped clamp 302 threadedly. A pressing block 304 is arranged inside the U-shaped clamp 302. The threaded end of the hand-tightening screw 303 is rotatably connected to the top groove of the pressing block 304 through a bearing. A grounding wire 305 is installed at the bottom end of the conductive sheet 301. One end of the grounding wire 305 is installed with a grounding electrode 306. The threaded end of the top of the sharp cone 401 is threadedly connected to the internal thread groove at the bottom of the grounding electrode 306. The round tube 402 is movably sleeved on the outer surface of the grounding electrode 306, and the inner wall of the round tube 402 is in contact with the outer surface of the grounding electrode 306. The cylindrical groove 405 is opened at the top of the inner wall of the bottom thread groove of the grounding electrode 306. The inner walls of both sealing rings 412 are in contact with the outer wall of the grounding electrode 306. An auxiliary ring 307 is fixedly sleeved on the outer surface of the grounding electrode 306 near the top position. The power distribution mechanism 1 includes a distribution box 101. A conductive block 114 is fixed to the other side of the distribution box 101 near the bottom position.

[0025] In this embodiment, when the grounding mechanism 3 of the power distribution equipment needs to be used, first turn the manual screw 303 to drive the pressing block 304 to move until the pressing block 304 can no longer move. Then move the U-shaped clamp 302 to dock the U-shaped clamp 302 with the conductive block 114. Next, reverse-rotate the manual screw 303 to reset the pressing block 304 to its original position. When the pressing block 304 is reset to its original position, with the cooperation of the U-shaped clamp 302, the manual screw 303, the pressing block 304 and the conductive block 114, the grounding mechanism 3 can be installed on the power distribution equipment. Then, insert the grounding electrode 306 into the soil on the ground through the cooperation of the auxiliary ring 307 and the sharp cone 401. When electric leakage occurs inside the power distribution equipment, the electricity on the distribution box 101 will directly be introduced into the ground through the cooperation of the conductive block 114, the conductive sheet 301, the grounding wire 305 and the grounding electrode 306. At this time, if a person touches the distribution box 101, the electricity on the distribution box 101 will not pass through the human body, thus avoiding electric shock accidents. When it is necessary to reduce the grounding resistance and improve the stability of the grounding mechanism 3 at the same time, before inserting the grounding electrode 306 into the soil on the ground, first remove the sharp cone 401. Then install two sealing rings 412 on the metal frame composed of the round tube 402, two inclined plates 404 and the rectangular grid plate 403 (sealing rings 412 are respectively installed in two installation grooves 411 on the round tube 402).

Then, with the cooperation of tools and two auxiliary blocks 408, move the two clamping bars 407 in opposite directions until the two clamping bars 407 can no longer move. Then, with the cooperation of tools and the fixing bolt 409, fix the two moved clamping bars 407. Then put the drying package 410 (the package of the drying package 410 is breathable, and the inside is water-absorbing molecular sieve particles, which can ensure the dryness of the internal space of the cylindrical groove 405, that is, reduce the rusting speed of the internal components of the cylindrical groove 405) into the internal of the cylindrical groove 405. Finally, install the sharp cone 401 back to its original position. When the installation operation of the metal frame on the grounding electrode 306 is completed, bury the grounding electrode 306 with the installed metal frame in the soil on the ground, that is, use the method of increasing the contact area between the grounding electrode 306 and the soil to reduce the grounding resistance. At the same time, this method (burying the grounding electrode 306 with the installed metal frame in the soil on the ground) can also improve the stability of the grounding mechanism 3 during use.

[0026] The effects and working principles achieved by the entire mechanism are as follows: When the power distribution equipment needs to be used, first install the entire power distribution equipment in a suitable position, and then open the box door 102 (such as Figure 2As shown, first move the external power - transmitting wire head inside the protective shell 103, then pass it through the through - hole at the top of the inner wall of the distribution box 101. After that, connect the power - transmitting wire head to the main power switch 107. Then, connect each miniature circuit breaker 113 to the load equipment that needs power supply through the prepared wires and the through - holes at the bottom of the inner wall of the distribution box 101 respectively. Next, connect the controller 110 to the external power supply through the through - holes at the bottom of the inner wall of the distribution box 101 and the prepared wires. After power - on, turn on the controller 110, set all the parameters. After parameter setting, wirelessly connect it to the monitoring equipment in the monitoring room through the cooperation of the antenna 104. When the grounding mechanism 3 of the power distribution equipment needs to be used, first turn the hand - screwed screw 303 to drive the pressure block 304 to move until the pressure block 304 can no longer move. Then move the U - shaped clamp 302 so that the U - shaped clamp 302 is docked with the conductive block 114. Then reverse - rotate the hand - screwed screw 303 to make the pressure block 304 return to its original position. When the pressure block 304 returns to its original position, with the cooperation of the U - shaped clamp 302, the hand - screwed screw 303, the pressure block 304 and the conductive block 114, the grounding mechanism 3 can be installed on the power distribution equipment. Then insert the grounding electrode 306 into the soil on the ground through the cooperation of the auxiliary ring 307 and the sharp cone 401. Then manually close the main power switch 107 and the molded - case circuit breaker 109, and at the same time use the controller 110 to close all the miniature circuit breakers 113. After closing, close the box door 102. When the main power switch 107, the molded - case circuit breaker 109 and all the miniature circuit breakers 113 have completed the closing operation, the power distribution equipment can be used. At this time, the external power - transmitting wire will transmit electricity to the inside of the closed molded - case circuit breaker 109 through the cooperation of the closed main power switch 107 and the first wire (commonly used wire in reality). Then, through the cooperation of the second wire (commonly used wire in reality), it is respectively transmitted to each closed miniature circuit breaker 113, and then transmitted to the corresponding load equipment through the corresponding wires, enabling the load equipment to work properly. At the same time, each current transformer 108 will detect the current value of the corresponding first wire and transmit the detected current data to the corresponding watt - hour meter 105 for display for on - site staff to view. At the same time, each current transformer 108 will also wirelessly transmit the detected current data to the monitoring equipment in the monitoring room through the cooperation of the controller 110 and the antenna 104 for the monitoring room staff to view. When the circuit has an over - current or short - circuit, the controller 110 will directly turn off all the miniature circuit breakers 113, and at the same time the main power switch 107 and the molded - case circuit breaker 109 will also trip automatically. At this time, all the load equipment connected to the power distribution equipment will lose power supply, which protects the load equipment from being damaged. When a sudden failure occurs inside the power distribution equipment, and the manual lock on the box door 102 is also damaged, and it is necessary to quickly open the box door 102,At this time, the staff in the monitoring room can, through the cooperation of the monitoring equipment in the monitoring room, antenna 104 and controller 110, start the electric push rod 207. Subsequently, the started electric push rod 207 will drive the two clamping blocks 206 connected thereto to move towards each other under the cooperation of the two sliding grooves 204 and the two sliding blocks 205. When the two sliding blocks 205 can no longer move, at this time, the controller 110 will pause the electric push rod 207. At this time, the opposite ends of the two clamping blocks 206 also just detach from the two rectangular blocks 203. At this time, the maintenance personnel in front of the power distribution equipment can horizontally move the box door 102 and remove the box door 102 from the distribution box 101 to perform emergency repair operations. When electric leakage occurs inside the power distribution equipment, at this time, the electricity on the distribution box 101 will directly be introduced into the ground through the cooperation of the conductive block 114, the conductive sheet 301, the grounding wire 305 and the grounding electrode 306. At this time, if a person touches the distribution box 101, the electricity on the distribution box 101 will not pass through the human body, thus avoiding electric shock accidents. When it is necessary to reduce the grounding resistance and improve the stability of the grounding mechanism 3 at the same time, before the grounding electrode 306 is inserted into the ground soil, first remove the sharp cone 401. Subsequently, install two sealing rings 412 on the metal frame composed of the round tube 402, the two inclined plates 404 and the rectangular grid plate 403 (install the sealing rings 412 in the two installation grooves 411 on the round tube 402 respectively). Then, put the metal frame with the sealing rings 412 on the grounding electrode 306. After that, use tools and the cooperation of the two auxiliary blocks 408 to make the two clamping strips 407 move in opposite directions until the two clamping strips 407 move to the position where they can no longer move. Then, use tools and the cooperation of the fixing bolts 409 to fix the two moved clamping strips 407. Then, put the drying packet 410 (the packaging of the drying packet 410 is breathable and the inside is water-absorbing molecular sieve particles) into the inside of the cylindrical groove 405. Finally, install the sharp cone 401 back to its original position. When the installation operation of the metal frame on the grounding electrode 306 is completed, at this time, bury the grounding electrode 306 with the installed metal frame in the soil on the ground, that is, use the method of increasing the contact area between the grounding electrode 306 and the soil to reduce the grounding resistance. At the same time, this method (burying the grounding electrode 306 with the installed metal frame in the soil on the ground) can also improve the stability of the grounding mechanism 3 during use.
