[0042] Embodiment 2:

[0043] Working principle: When the structure is in use, the rolling wheel 301 of the track transport mechanism 3 is used to move the structure to the specified position through the track, and the grounding protection mechanism 6 is used to locate the parking position of the structure to prevent it from moving. When falling rocks hit the top of the structure, the anti-smashing mechanism 8 will push the falling rocks to make them slide down to avoid the accumulation of falling rocks and crushing the mining transformer 10. The shock absorbing mechanism 7 absorbs the impact of falling rocks to prevent damage to the internal parts of the mining transformer 10. The balancing mechanism 9 absorbs the impact and reduces the height of one side of the anti-smashing mechanism 8 to facilitate the rolling of falling rocks. The maintenance door 2 is opened and the required circuit is fixedly connected. After the connection is completed, the maintenance door 2 is closed. The cooling mechanism 11 absorbs the heat generated by the mining transformer 10 during operation. The air enters from the air inlet 5, cools the cooling mechanism 11, and is blown out from the air outlet 4 through the cooling mechanism 11.

[0044] When the grounding protection mechanism 6 is used to locate the parking position of the structure, the pedal 601 is stepped on with the foot, and the pedal 601 moves downward to drive the sliding column 603 to move downward, and the sliding column 603 moves downward to drive the limit block 607 to move downward, and the sliding column 603 moves downward to drive the locking block 604 to move downward, and the limit block 607 moves downward to squeeze the contraction spring 606. After the pedal 601 contacts the ground, the locking block 604 moves to the bottom of the locking plate 602, and the pedal 601 is moved to one side by the foot, and the pedal 601 rotates to one side to drive the sliding column 603 to rotate to one side, and the sliding column 603 rotates to one side to drive the locking block 604 to rotate to one side. At this time, the grounding protection mechanism 6 is locked, and the pedal 601 contacts the ground. The teeth on the lower surface of the pedal 601 are embedded in the ground to increase friction and prevent it from moving. When the equipment leaks or the insulation is damaged, the grounding protection mechanism 6 can introduce current into the ground.

[0045] When falling rocks hit the top of the structure, the anti-smashing mechanism 8 starts to work, and the falling rocks hit the roller 802. The falling rocks press the roller 802 to move downward, and the roller 802 moves downward to push the lifting block 805 to move downward. The lifting block 805 moves downward to compress the lifting spring 804. The upper side surface of the protective cover 801 is an arc surface. Most of the falling rocks are irregular objects. The falling rocks slide to one side under the guidance of gravity, driving the roller 802 to roll. After the falling rocks fall, the lifting spring 804 releases the pressure to push the lifting block 805 to move upward. The lifting block 805 moves upward to push the roller 802 to move upward. The roller 802 rolls and pushes the falling rocks off the protective cover 801 to prevent the accumulation of falling rocks from crushing the mining transformer 10.

[0046] When the shock absorbing mechanism 7 is working, the falling rocks press the protective cover 801 to move downward, and the downward movement of the protective cover 801 pushes the guide rail 701 to move downward. The downward movement of the guide rail 701 pulls the two sliding seats 703 to slide in the opposite direction. The two sliding seats 703 slide in the opposite direction to stretch the tension spring 702. The two sliding seats 703 slide in the opposite direction to drive the connecting rod 704 to rotate in the opposite direction with the fixed seat 705 as the center. After the falling rocks fall, the tension spring 702 contracts and pulls the two sliding seats 703 to slide toward each other. The two sliding seats 703 slide in the opposite direction to drive the connecting rod 704 to rotate in the opposite direction with the fixed seat 705 as the center. The connecting rod 704 rotates in the opposite direction with the fixed seat 705 as the center to push the guide rail 701 to move upward. The upward movement of the guide rail 701 pushes the protective cover 801 to reset. The shock absorbing mechanism 7 absorbs the impact force of the falling rocks to prevent the internal parts of the mining transformer 10 from being damaged.

[0047] When the balancing mechanism 9 is working, the falling rocks press the protective cover 801 to move downward, and the protective cover 801 moves downward to push the energy absorbing shaft 908 to move downward, and the energy absorbing shaft 908 moves downward to compress the energy absorbing spring 909, and the energy absorbing shaft 908 moves downward to push the trigger block 907 to move downward. Under the action of the side inclined surface of the trigger block 907, the trigger block 907 moves downward to push the driven block 902 to slide to one side. If the impact force of the falling rocks is large, the driven block 902 moves downward synchronously, and the driven block 902 moves downward to drive the balancing shaft 901 to move downward, and the balancing shaft 901 moves downward to pull the sliding sleeve 904 to move downward, and the sliding sleeve 904 moves downward to push the sliding shaft 905 to slide downward, and the sliding sleeve 904 moves downward to compress the reset spring 906, and the driven block 902 slides to one side to squeeze the compression spring 903, and the driven block 902 slides to one side to push the balancing shaft 901 to slide to one side, and the balancing shaft 901 moves to The sliding on one side pushes the driven block 902 at the other end to slide to one side. Under the action of the side inclined surface of the trigger block 907, the driven block 902 at the other end slides to one side and pushes the trigger block 907 on the other side to move upward. The upward movement of the trigger block 907 on the other side pushes the energy absorbing shaft 908 on the other side to move upward. The upward movement of the energy absorbing shaft 908 on the other side pushes the other end of the protective cover 801 to move upward. At this time, the protective cover 801 is tilted, which is convenient for the anti-smashing mechanism 8 to push the falling rocks to make them slide. After the falling rocks fall, the energy absorbing spring 909 releases the pressure, pushes the energy absorbing shaft 908 to reset, and the energy absorbing shaft 908 resets and pulls the protective cover 801 to reset. The reset spring 906 releases the pressure and pushes the sliding sleeve 904 to move upward. The sliding sleeve 904 moves upward and pushes the balancing shaft 901 to reset. The compression spring 903 releases the pressure to pull the driven blocks 902 at both ends of the balancing shaft 901 to reset. At this time, the balancing mechanism 9 recovers its balance.

[0048] When the cooling mechanism 11 is working, the heat generated by the mining transformer 10 is transferred to the heat dissipation fins 1106 through the isolation plate 1101, and the circulating pump 1105 extracts the coolant from the collection box 1104 and sends it to the heat conduction pipe 1102. The coolant absorbs the heat of the heat dissipation fins 1106 in the heat conduction pipe 1102, and the air enters the structure through the air inlet filter 501 to cool the coolant and the heat dissipation fins 1106. The air that absorbs the heat is blown to the outside of the structure by the fan 1103 through the air outlet 4. After the coolant is cooled, it flows back to the collection box 1104. The air outlet 4 is in a closed state when the mining transformer 10 is turned off.
