When the pile body 2 works, the pile body 2 is located inside a foundation pit, and the pile body 2 is provided with high voltage electricity, so that if the charging pile is arranged in an outdoor open environment, rainwater is easy to collect inside the foundation pit in rainy and snowy weather, water enters the pile body 2, the pile body 2 is damaged, and meanwhile, the high voltage electricity is leaked, so that potential safety hazards are caused; therefore, in the scheme, the sealing ring 18 is arranged at the edge of the foundation pit, so that when the hydraulic cylinder 13 drives the pile body to rotate and close, the rotating plate 15 is pressed to the sealing ring 18 under the pressure action of the hydraulic cylinder 13, the rotating plate 15 and the sealing ring 18 are sealed, a water flow channel at the upper part of the foundation pit is blocked, rainwater is prevented from flowing into the interior of the foundation pit, the pile body 2 is prevented from being damaged by water, and the safety of the pile body 2 is ensured; meanwhile, the leakage of a high-voltage zone in the pile body 2 is avoided, and the safety of the charging pile is improved.

As shown in fig. 7, one side of the foundation pit is provided with an extraction hole 19; heat dissipation holes 20 are formed in the side wall and the top surface of the casing of the pile body 2, which are close to the hydraulic cylinder 13; a heat dissipation hole 20 on one side wall of the casing of the pile body 2 close to the hydraulic cylinder 13 is opposite to the air suction hole 19.

When the pile is in operation, a large amount of heat is generated in the using process of the charging pile, if the pile directly enters the foundation pit after the pile is used, the air fluidity inside the foundation pit is poor, and the heat dissipation of the pile body 2 is poor, so that the heat dissipation of the pile body 2 is poor, through arranging the heat dissipation holes 20 on the top surface and the back surface of the pile body 2, and further after the pile body 2 enters the foundation pit, the position close to the heat dissipation hole 20 on the back surface of the pile body 2 is provided with the air suction hole 19, and further in the process of exhausting gas outwards along with the air suction hole 19, because the air suction hole 19 is right opposite to the heat dissipation hole 20 on one side of the pile body 2, the heat inside the pile body 2 can be rapidly taken away, and meanwhile, through arranging the heat dissipation holes 20 on the top surface of the pile body 2, when the heat dissipation holes 20 on the back surface take the heat inside the pile body 2 out in the air suction process of the air suction hole 19, the air with lower temperature is sucked into the pile body 2 by the heat dissipation holes 20 on the top surface, thereby accelerating the heat dissipation of the pile body 2.

As shown in fig. 8, the invention also discloses a new energy automobile charging pile centralized auxiliary system, which comprises an air pump 21, a refrigeration part, a connecting pipe 23, a valve 24 and a control box 25; one port of the valve 24 is communicated with the air suction hole 19; the other port of the valve 24 is communicated with the connecting pipe 23; one end of the connecting pipe 23 is communicated with the air pump 21; the other end of the connecting pipe 23 is communicated with the refrigerating part; the air pump 21 and the refrigeration component are both electrically connected with the control box 25; the controller is located inside the control box 25.

When the pile body 2 works, a large amount of heat is generated in the using process of the charging pile, and if the pile body directly enters the interior of a foundation pit after the charging pile is used, the heat dissipation of the pile body 2 is poor due to poor air fluidity in the interior of the foundation pit; meanwhile, because the foundation pit is positioned in the stratum, the humidity of the air in the foundation pit is higher, and most of the air in the pile body 2 is electronic elements, so that the risk of damaging the electronic elements is increased; therefore, in the scheme, after the charging pile is used, in the process that equipment of the pile body 2 enters the interior of the skill, under the control of the control box 25, the air pump 21 in the system works to pump out air in the foundation pit, so that air inside the foundation pit and air outside the foundation pit are driven to circulate, heat on the pile body 2 is taken away, a heat dissipation effect is achieved, meanwhile, the air flows outwards along with the air inside the foundation pit, so that moisture inside the foundation pit is driven to flow outwards, the humidity inside the foundation pit is reduced, electronic elements in the pile body 2 are prevented from being damped and damaged, and the electronic failure rate of the pile body 2 is reduced; after foundation ditch upper portion is sealed, dry cold air is washed into to the foundation ditch inside through the refrigeration part in the system, and then reduces the inside temperature of foundation ditch, and then has increased the temperature difference of pile 2 and environment, and then has accelerated the speed of the heat outdiffusion of pile 2, and then has accelerated the heat dissipation of pile 2, and then has avoided the components and parts ageing or damage that pile 2 high temperature caused, and then has improved the life of pile 2.

When the parking device works, after a vehicle stops in the parking space, the signal triggering component 1 transmits a signal to the controller after monitoring the vehicle, the controller receives the signal and waits for 10-20 seconds (after the vehicle completely stops stably), the controller controls the sealing component to be opened and the lifting component 3 to be lifted upwards so as to lift the pile body 2 above the ground, so that a user can conveniently charge the vehicle, after the vehicle leaves the parking space range after the charging is finished, the signal triggering component 1 transmits the signal to the controller, the controller controls the lifting component 3 to bring the pile body 2 into the interior of the foundation pit, the sealing component 4 is closed, so that the foundation pit is sealed, so that the pile body 2 enters the sealed environment in the interior of the foundation pit, and because the pile body 2 is positioned in the interior of the foundation pit and the upper portion of the foundation pit is sealed in the parking process, furthermore, objects which shield the vehicles to run are not arranged near the parking spaces, so that the vehicles can be conveniently parked, and meanwhile, the pile bodies 2 are positioned in the foundation pit, so that even if a driver has improper operation, the pile bodies 2 cannot be impacted, the risk that the pile bodies 2 are impacted by the vehicles is avoided, and the safety of the pile bodies 2 is further ensured; meanwhile, under the condition that the pile body 2 is not charged, the pile body 2 is located in the closed environment in the foundation pit, so that the condition that the pile body 2 is directly exposed in the environment is reduced, the aging speed caused by erosion of the pile body 2 is reduced, and the service life of the pile body 2 is prolonged; meanwhile, as the pile body 2 is positioned in a closed environment inside the foundation pit, dust and sundries are prevented from entering the pile body 2, so that the erosion of the dust and the sundries to the pile body 2 is reduced, and the neatness of the pile body 2 is improved; if the signal triggering part 1 detects the parking condition of the vehicle through sensors such as an infrared sensor or a photoelectric sensor, when a person passes through the position of the sensor, the sensor is easily misjudged, so that the pile body 2 is ineffective to move up and down, further frequent misoperation of equipment is caused, and further the risk of equipment damage is increased; therefore, in the scheme, when the vehicle is parked, the rear wheel of the vehicle collides and is pressed on the movable plate 6, so that the movable plate 6 slides towards the inside of the groove, and the movable plate 6 presses the pressure sensor 7 (when the pressure applied to the pressure sensor 7 exceeds 400N, the pressure sensor 7 transmits a signal to the controller), because the pressure sensor 7 can be triggered only when the added pressure is required to be reached, the pressure sensor 7 cannot be triggered when a pedestrian or other animals trample the movable plate 6, so that false triggering of the signal cannot be caused, and further the invalid up-and-down movement of the pile body 2 cannot be caused, so that the moving frequency of the pile body 2 is reduced, and the risk of equipment damage is reduced; after the vehicle drives away, the movable plate 6 is reset under the action of the elastic force of the spring 8, so that the pressure sensor 7 conveniently transmits the driving-away signal of the vehicle to the controller, and the pile body 2 is controlled to enter the foundation pit; meanwhile, the signal trigger device is arranged, so that the vehicle is prevented from moving backwards, information of reminding a driver of stopping the vehicle in place can be played, the situation that the vehicle presses the sealing part 4 to block the opening of the foundation pit is avoided, faults are avoided, and the running safety of the equipment is improved; after the use of the charging pile is finished, in the process that equipment of the pile body 2 enters the interior of the skill, under the control of the control box 25, the air pump 21 in the system works to pump out air in the foundation pit, so that air inside the foundation pit and outside air are driven to circulate, heat on the pile body 2 is taken away, a heat dissipation effect is achieved, meanwhile, as the air inside the foundation pit flows outwards, moisture inside the foundation pit is driven to flow outwards, the humidity inside the foundation pit is reduced, electronic elements in the pile body 2 are prevented from being affected with damp and damaged, and the electronic failure rate of the pile body 2 is reduced; after foundation ditch upper portion is sealed, dry cold air is washed into to the foundation ditch inside through the refrigeration part in the system, and then reduces the inside temperature of foundation ditch, and then has increased the temperature difference of pile 2 and environment, and then has accelerated the speed of the heat outdiffusion of pile 2, and then has accelerated the heat dissipation of pile 2, and then has avoided the components and parts ageing or damage that pile 2 high temperature caused, and then has improved the life of pile 2.
