The spiral grounding can increase the contact area between the grounding and dredging end and the soil layer, thereby improving the efficiency of the grounding and dredging. Moreover, when performing grounding and dredging, the dredging end does not need to be in contact with the soil layer all the time, thereby increasing the stability of the dredging end during use, thereby avoiding the dredging end being in contact with the soil layer all the time during the dredging process, which may cause damage to the dredging end over time and result in inability to use normally. Furthermore, the soil layer can be detected before grounding and dredging. If an abnormality in the soil layer is detected, the dredging can be stopped, and the charging pile body can be shut down and stopped from being used, thereby avoiding use under abnormal circumstances, which may lead to accidents.

A cleaning brush head 206 is installed on the left side of the movable slide 208, and a rotating piece is installed on the left side of the cleaning brush head 206 through a bearing. A mounting spring 205 is sleeved on the outside of the movable slide 208. The top and bottom ends of the inner cavity of the docking frame head 202 are provided with mounting grooves 204. A mounting slider 203 is slidably installed on the front side of the inner cavity of the mounting groove 204. A movable ejector rod 207 is installed on the end of the mounting slider 203 away from the mounting groove 204. A rubber docking joint is installed on the end of the movable ejector rod 207 away from the mounting slider 203. A mounting spring 205 is installed on the right side of the mounting slider 203.

[0034] A plurality of docking tubes 211 are equidistantly installed on the right side of the docking frame head 202, and the right end of the movable slide rod 208 extends to the left side of the inner cavity of the docking tube 211 and is installed with a connecting rotating block 217 through a bearing. An extrusion airbag 212 is installed on the right side of the connecting rotating block 217, and the right end of the extrusion airbag 212 is connected to the right side of the inner cavity of the docking tube 211.

[0035] The specific implementation is as follows: when the charging gun 7 is used up and the gun head is engaged with the inside of the recovery port 201 for reset, the gun head first contacts the movable push rod 207. When the gun head continues to move, the movable push rod 207 pushes the installation slide block 203 to slide inside the installation slide groove 204, squeezing the installation spring 205. When the installation slide block 203 slides inside the installation slide groove 204, the connecting rope 501 is in a relaxed state, and the rebound spring bar 504 loses its restraining force. The rotational force generated by the loosening of the rebound spring bar 504 drives the rotating rod 503 to rotate. When the rotating rod 503 rotates, it drives the transmission wheel 506 to rotate, and drives the connecting wheel 512 to rotate through the rotating belt 507. The mounting sleeve 210 is driven to rotate through the connecting wheel 512, which drives the movable slide bar 208 to rotate and drives the cleaning brush head 206 to rotate. When the gun head moves toward the inside of the docking frame head 202, the cleaning brush head 206 and the inside of the gun head are in contact. If the charging hole is in contact with the charging core, the inside of the charging hole is cleaned, and the movable slide bar 208 is pushed to drive the connecting rotating block 217 to slide inside the docking tube 211, and the squeezing airbag 212 is squeezed to transport the air inside the squeezing airbag 212 to the inside of the connecting tube 215, and the movable piston 216 is pushed to slide inside the connecting tube 215, so that the movable piston 216 contacts and squeezes the pressure control switch 213. If there is no blockage inside the charging hole or the charging core is intact, the pressure value generated by the pressure control switch 213 when it is squeezed is within a certain threshold. When there is dirt inside the charging hole or there is an abnormality in the charging core, the value generated by the pressure control switch 213 is not within the threshold range, and when the charging gun 7 is not completely reset after use, the pressure control switch 213 will not be triggered, and an alarm will be issued through the alarm head inside the control panel to tell the staff and the people to be used not to use it if there is an abnormality.

[0036] The rotating evacuation mechanism 5 also includes a connecting rope 501, a rebound spring 504, a rotating wheel 505, a transmission wheel 506, a rotating belt 507, a gathering frame head 508, a gathering fan head 509, a connecting air pipe 510, an annular air channel 511, a connecting wheel 512, a pressure controller 513, an arc-shaped slider 514, an arc-shaped slide groove 515 and an extrusion spring 516. The connecting rope 501 is installed on the rear side of the top mounting slider 203, and the rebound spring 504 in a compressed state is installed on the left side of the rotating rod 503. One end of the rebound spring bar 504 is connected to the upper end of the inner cavity of the mounting frame 502. The rotating rod 503 is located on the right side of the rebound spring bar 504 and is installed with a rotating wheel 505. The end of the connecting rope 501 away from the mounting slider 203 passes through the docking frame head 202 and is connected to the outside of the rotating wheel 505. The rotating rod 503 is located on the right side of the rotating wheel 505 and is installed with a transmission wheel 506. The right end of the mounting sleeve 210 is installed with a connecting rotating wheel 512. The transmission wheel 506 and the connecting rotating wheel 512 are externally mounted with a rotating belt 507.

[0037] A gathering frame head 508 is installed on the upper right end of the installation frame 502, and a gathering fan head 509 is installed inside the gathering frame head 508 at the right end of the rotating rod 503 through the installation frame 502. A connecting air pipe 510 is installed on the right end of the gathering fan head 509. An annular air channel 511 is opened on the right side of the inner cavity of the docking frame head 202, and a plurality of air holes are opened at equal distances on the left side of the annular air channel 511. Nozzles are installed around the right side of the inner cavity of the docking frame head 202 at relative positions of the air holes. The end of the connecting air pipe 510 away from the gathering frame head 508 extends to the upper end of the inner cavity of the annular air channel 511. The installation sleeve An arc-shaped chute 515 is provided around the outside of the block 210, and an arc-shaped slider 514 is installed at the top of the inner cavity of the connecting wheel 512. The bottom end of the arc-shaped slider 514 is slidably connected to one side of the upper end of the inner cavity of the arc-shaped chute 515. An extrusion spring 516 is installed on the rear side of the arc-shaped slider 514. The end of the extrusion spring 516 away from the arc-shaped slider 514 is connected to the inner cavity of the arc-shaped chute 515. A pressure controller 513 is installed at the end of the inner cavity of the arc-shaped chute 515 away from the arc-shaped slider 514. The pressure controller 513 is electrically connected to the control panel. The mounting block 210 has an outer circle and an inner square structure.

[0038] The specific implementation is as follows: when the connecting wheel 512 rotates, it drives the arc-shaped slider 514 to slide inside the arc-shaped slot 515 and squeezes the squeezing spring 516, which is later reset by the squeezed squeezing spring 516. After the arc-shaped slider 514 slides inside the arc-shaped slot 515, it will contact and squeeze the pressure controller 513. If there is no adhesive dirt inside the charging hole, the value generated by the pressure controller 513 is in a small threshold range. If there is adhesive dirt inside the charging hole, the pressure generated by the pressure controller 513 will be greater, and the alarm will be fed back through the alarm of the control panel. When the charging gun 7 is removed, the compressed mounting spring 205 pushes the mounting slider 203 to slide and reset inside the mounting slot 204, and drives the rotating rod 503 to reverse through the connecting rope 501. Since the fan blades of the gathering fan head 509 are in a reversed structure, when the rotating rod 503 rotates When the charging gun 7 is removed, the gathering fan head 509 is driven to rotate inside the gathering frame head 508, and an airflow is generated inside the gathering frame head 508, and the airflow is transported to the inside of the annular airway 511 through the connecting air pipe 510. When the charging gun 7 is removed, the recovery port 201 and the docking frame head 202 are cleaned by the airflow to avoid the accumulation of dirt inside the recovery port 201 and the docking frame head 202, which cannot be processed in time. During the use of the charging pile body 1, the charging end can be monitored, and whether the charging end is successfully reset after use is completed can be monitored. If charging is abnormal under long-term use, it can be discovered in the first time and processed in time. At the same time, the charging end and the charging area can be processed to avoid the presence of debris or dirt in the charging end and the charging area under long-term use, which cannot be discovered in time and affects the efficiency of later use.

When the rotating rod rotates, it drives the movable ring 308 to rotate, driving the mounting ring rail 313 to slide outside the stabilizing ring bar 312, increasing the stability of the movable ring 308 when rotating. When the movable ring 308 rotates, it drives the pushing cone blocks 311 on both sides to rotate, so that the pushing cone blocks 311 contact the inclined surface of the moving cone block 310, and pushes the moving cone block 310 to move. The cone block 310 moves and pushes the connecting rod 304 and the movable rod 303 to move to the side away from the pushing cone block 311, and squeezes the installation movable spring 302 through the connecting rod 304. Later, the installation movable spring 302 is reset after squeezing, and the evacuation mesh plate 301 is driven to move and separate from the inside of the installation opening through the movable rod 303. This operation can make the evacuation mesh plate 301 move back and forth inside the installation opening, and can not only improve the efficiency of the evacuation process, but also avoid being blocked by external debris at the outdoor evacuation end, affecting the normal evacuation operation, and causing damage to the electronic components inside the charging pile body 1.

An adsorption magnetic block is installed on the left side of the movable slider 408. There is a fixed electromagnetic block 407, a mounting rod 404 is installed on the right side of the bottom end of the inner cavity of the charging pile body 1, and a blocking top block 405 is installed on the top of the mounting rod 404. The mounting rod 404 is made of rubber material, and a movable slot 417 is provided on the rear side and left side of the middle and lower end of the inner cavity of the fixed slide 401. The movable slot 417 is L-shaped when viewed from above, and a movable limit block 410 is movably installed on the middle and lower end of the inner cavity of the fixed slide 401. The left end of the movable limit block 410 is located inside the movable slot 417, and a touch timing switch is installed at the rear end of the left side of the inner cavity of the movable slot 417. A push rod 416 is installed on the left end of the movable limit block 410, and a movable hole is provided at the front end of the inner cavity of the movable slot 417 on the left side. A docking piece is installed at the front end of the push rod 416 through the movable hole, and a connecting movable spring 415 is installed on the outer front end of the push rod 416. The fixed electromagnetic block 407, the single-phase motor 414 and the touch timing switch are electrically connected to the control panel;

[0042] The right end of the movable slider 408 passes through the fixed slide cylinder 401 and is equipped with a fixed frame head 413. The bottom end of the fixed frame head 413 is equipped with a pushing cylinder 412 through a bearing. A number of balls are equidistantly and movably installed around the outside of the pushing cylinder 412. The bottom end of the pushing cylinder 412 is a conical structure. A single-phase motor 414 is installed on the right side of the inner cavity of the fixed frame head 413 through a mounting seat. A retracting roller 409 is installed on the left side of the inner cavity of the fixed frame head 413 through a mounting seat. A limiting rope 411 is wrapped around the outside of the retracting roller 409. A movable long groove is provided on the left side of the top of the fixed frame head 413. The top of the limiting rope 411 passes through the movable long groove and is connected to the bottom end of the movable ring 308. A movable rotating rod is installed on the left end of the single-phase motor 414, and the left end of the movable rotating rod is connected to the retracting roller 409. A sealing rubber sheet is installed on the bottom end of the inner cavity of the mounting slide hole, and a round hole is provided in the middle of the rubber sealing sheet.

[0043] The specific implementation is as follows: when the charging pile body 1 is in use, if leakage or static electricity accumulation occurs and is detected by the power monitor 9, or when encountering abnormal weather, the staff starts the servo motor 305 through the control panel, and drives the movable ring 308 to rotate, and at the same time disconnects the power supply of the fixed electromagnetic block 407, so that the fixed electromagnetic block 407 loses its magnetism, and the movable slider 408 loses its restraint force, and the pushing spring 406 in a compressed state drives the movable slider 408 to move toward the lower end of the inner cavity of the fixed slide cylinder 401, and the fixed frame head 413 and the pushing cylinder 412 are driven downward by the movable slider 408. When the movable slider 408 moves downward, it will be blocked by the movable limit block 410. When the moving slider 408 is moved completely to the bottom end of the fixed slide 401, the moving push cylinder 412 is rotated after the drive movement, so that the push cylinder 412 contacts the arc structure of the push block 402, and the spiral plug rod 403 is driven to rotate in a spiral shape by the push block 402. When the spiral plug rod 403 is rotated in a downward spiral, the spiral plug rod 403 is inserted into the soil layer for grounding and conductivity. When the spiral plug rod 403 drives the push block 402 to move downward, the push block 402 is separated from the bottom end of the push cylinder 412. When the fixed slide 401 rotates, the side of the fixed slide 401 away from the push rod 416 contacts the blocking top block 405, and the blocking top block 405 is contacted and squeezed, so that the installation rod 404 is produced. When the fixed slide 401 continues to move due to deformation, it is separated from the blocking top block 405 and reset by the squeezed installation rod 404. When the conduction is completed, the fixed slide 401 is driven to reverse, which drives the pushing cylinder 412 to reverse. When the pushing rod 416 rotates to the position of the blocking top block 405, it drives the movable limit block 410 to move to the side of the movable groove 417 through the pushing rod 416. When the pushing rod 416 moves, it squeezes the connecting movable spring 415. Later, the pushing rod 416 and the movable limit block 410 are reset by the squeezed connecting movable spring 415. When the movable limit block 410 moves to the rear side of the inner cavity of the movable groove 417 and triggers the control panel with the touch timing switch, The movable slider 408 loses its restraining force, and the movable slider 408 continues to move downward, and drives the fixed frame head 413 and the pushing cylinder 412 to continue to move downward, so that the pushing cylinder 412 contacts the pushing block 402, and drives the spiral insertion rod 403 to rotate in the opposite direction, so that the spiral insertion rod 403 gradually moves upward, and drives the pushing block 402 to move upward, completing the resetting of the spiral insertion rod 403. When the resetting is completed, the touch timing switch is triggered to trigger the control panel to start the single-phase motor 414 and the fixed electromagnetic block 407, and the single-phase motor 414 drives the retracting roller 409 to rotate, winds and collects the limit rope 411, and drives the fixed frame head 413, the pushing cylinder 412 and the movable slider 408 to move upward and reset.

[0044] The humidity detection mechanism 6 includes a detection cavity 601, a humidity detector 602, and a detection plug 603. The detection plug 603 is installed at the bottom end of the spiral rod 403. The detection cavity 601 is defined within the detection plug 603. Humidity detectors 602 are installed on both sides of the detection cavity 601. A number of seepage holes are evenly spaced around the interior of the detection cavity 601. The detection plug 603 is made of an insulating material.

[0045] The specific implementation is as follows: when the spiral rod 403 rotates downward, it drives the detection plug 603 to move, so that the detection plug 603 passes through the middle of the sealing rubber sheet. When the circular hole is squeezed and pushed open, the rubber sealing sheet contacts and rubs with the outside of the detection plug 603 for cleaning. When the detection plug 603 is inserted into the soil layer at the bottom of the charging pile body 1, if the humidity inside the soil layer is too high, the humidity detector 602 installed inside the detection cavity 601 will detect that the humidity is too high, triggering the control panel to shut down the servo motor 305 and stop pushing the spiral rod 403 to continue moving downward, so as to avoid excessive humidity at the bottom of the charging pile body 1. If grounding is performed to release electrical energy, it will cause a safety hazard to the surrounding area. At the same time, the charging pile body 1 is shut down and stopped from being used to avoid accidents.

[0046] Working principle: When the charging gun 7 of the present invention is used up and the gun head is engaged with the inside of the recovery port 201 for reset, the gun head first contacts the movable top rod 207. When the gun head continues to move, the movable top rod 207 pushes the installation slide block 203 to slide inside the installation slide groove 204, squeezing the installation spring 205. When the installation slide block 203 slides inside the installation slide groove 204, the connecting rope 501 is in a relaxed state, and the rebound spring bar 504 loses its restraining force. The rotational force generated by the loosening of the rebound spring bar 504 drives the rotating rod 503 to rotate. When the rotating rod 503 rotates, it drives the transmission wheel 506 to rotate, and drives the connecting wheel 512 to rotate through the rotating belt 507. The mounting sleeve 210 is driven to rotate through the connecting wheel 512, which drives the movable slide bar 208 to rotate and drives the cleaning brush head 206 to rotate. When the gun head moves toward the inside of the docking frame head 202, the cleaning brush head 206 and the inside of the gun head are in contact. If the charging hole is in contact with the charging core, the inside of the charging hole is cleaned, and the movable slide bar 208 is pushed to drive the connecting rotating block 217 to slide inside the docking tube 211, and squeeze the squeezing airbag 212 to transport the air inside the squeezing airbag 212 to the inside of the connecting tube 215, and then the movable piston 216 is pushed to slide inside the connecting tube 215, so that the movable piston 216 contacts and squeezes the pressure control switch 213. If there is no blockage inside the charging hole or the charging core is intact, the pressure value generated by the pressure control switch 213 when squeezing is within a certain threshold. When there is dirt inside the charging hole or the charging core is abnormal, the value generated by the pressure control switch 213 is not within the threshold range, and if the charging gun 7 is not completely reset after use, the pressure control switch 213 will not be triggered, and an alarm will be issued through the alarm head inside the control panel to tell the staff and the people to be used not to use it if there is an abnormality.

[0047] When the connecting wheel 512 rotates, it drives the arc-shaped slider 514 to slide inside the arc-shaped slot 515 and squeeze the squeezing spring 516. Later, the squeezing spring 516 is reset. After the arc-shaped slider 514 slides inside the arc-shaped slot 515, it will contact and squeeze the pressure controller 513. If there is no adhesive dirt inside the charging hole, the value generated by the pressure controller 513 is in a small threshold range. If there is adhesive dirt inside the charging hole, the pressure generated by the pressure controller 513 will be greater, and an alarm will be fed back through the alarm on the control panel. When the charging gun 7 is removed, the compressed state is released. The spring 205 pushes the installation slider 203 to slide and reset inside the installation slide groove 204, and drives the rotating rod 503 to reverse through the connecting rope 501. Since the fan blades of the gathering fan head 509 are in a reversed structure, when the rotating rod 503 rotates, it drives the gathering fan head 509 to rotate inside the gathering frame head 508, and generates airflow inside the gathering frame head 508. The airflow is transported to the inside of the annular airway 511 through the connecting air pipe 510. When the charging gun 7 is removed, the recovery port 201 and the docking frame head 202 are cleaned by the airflow to avoid dirt accumulating inside the recovery port 201 and the docking frame head 202 and failing to deal with it in time.
