[0039] Reference Figure 3 , Figure 5 and Figure 6 , wherein the heat dissipation component includes a cooling groove 6, which is arranged at the bottom of the inner cavity of the charging pile body 1, and a cooling part is arranged in the cooling groove 6. An air inlet groove 61 and an exhaust groove 62 are respectively arranged on both sides of the cooling groove 6. The cooling groove 6 is filled with cooling water, and the liquid level of the cooling water is lower than the ports of the air inlet groove 61 and the exhaust groove 62. The input end of the air inlet groove 61 is connected to the middle of the empty groove of the charging pile body 1, and the output end of the exhaust groove 62 is connected to the inner cavity of the collection groove 4.

When the exhaust fan blade 64 rotates, a suction effect will be generated on the side of the cooling tank 6 close to the air inlet slot 61, so that the external airflow passes through the air inlet filter 68 and enters the cooling tank 6 along the air inlet slot 61, thereby realizing the preliminary filtration of the airflow. In this process, with the action of the vibration spring 682 and the wind resistance, the air inlet filter 68 will be caused to reciprocate and shake, thereby shaking off the dust attached to the windward surface of the air inlet filter 68, thereby ensuring the use effect of the air inlet filter 68, and a thrust effect will be generated on the side close to the exhaust slot 62, so that the airflow enters along the The exhaust groove 62 enters the collecting groove 4 and is finally discharged from the air outlet groove 63, thereby accelerating the air flow exchange speed inside the charging pile body 1, realizing ventilation and heat dissipation, and improving the protection effect of the electrical equipment and components inside the charging pile body 1.

A filter residue net 671 is provided at the connection between the bottom of the filter box 67 and the drainage groove 654.

[0042] Through the arrangement of the above-mentioned structure, the linkage ring 652 will drive the pumping blade 655 to rotate, so that a diversion effect is generated in the cavity of the driven shaft 651 and the linkage ring 652, so that the water in the cooling trough 6 flows along the pumping trough 653, the cavity of the driven shaft 651, the cavity of the linkage ring 652 and the drainage trough 654 into the filter box 67, and after being filtered by the filter residue net 671, it is discharged back into the cooling trough 6 from the output end of the drainage trough 654, so as to collect the dust intercepted in the water flow, which improves the neatness of the water flow and reduces the friction of the dust on the pumping blade 655, thereby ensuring the durability of the pumping blade 655.

[0043] Reference Figure 3 , Figure 4 , Figure 8 and Fig.10 , wherein the cleaning mechanism includes a negative pressure box 7, which is fixed in the exhaust groove 62, a positioning rod 71 is fixedly connected to the inner wall of the negative pressure box 7, a trigger rod 72 is slidably sleeved on the positioning rod 71, the end of the positioning rod 71 is slidably connected in the trigger rod 72, and a trigger spring 721 is fixedly connected between the end of the positioning rod 71 and the inner wall of the trigger rod 72, the end of the trigger rod 72 extends through the storage groove 31, and an adsorption groove 722 is provided in the trigger rod 72, a pneumatic impeller 73 is rotatably connected to the outer wall of the negative pressure box 7, a piston groove 74 is provided on the inner wall of the exhaust groove 62, a piston plate 741 is slidably connected in the piston groove 74, a reset spring 742 is fixedly connected between the side wall of the piston plate 741 and the piston groove 74, and the side wall of the pneumatic impeller 73 A magnetic plate 731 is fixedly connected to it, and the outer wall of the pneumatic impeller 73 is wrapped with a water-absorbing sponge for absorbing moisture contained in the airflow in the exhaust groove 62. The magnetic plate 731 and the piston plate 741 repel each other magnetically. The piston groove 74 is connected to the negative pressure box 7 through the air extraction groove 75. An air pushing groove 751 is provided on the top of the piston groove 74. The input end of the air pushing groove 751 passes through the charging pile body 1 and is connected to the outside world, and both the air extraction groove 75 and the air pushing groove 751 are provided with a one-way valve; a small cross groove 76 is provided at the end of the trigger rod 72, and the small cross groove 76 is connected to the inner cavity of the adsorption groove 722; a large cross groove 761 is provided on the side wall of the storage groove 31, and when the trigger rod 72 is fully retracted, the large cross groove 761 is connected to the small cross groove 76.

[0044] It should be noted that the one-way valve in the air extraction groove 75 can only allow the gas in the negative pressure box 7 to enter the piston groove 74; the one-way valve in the air pushing groove 751 can only allow the gas in the piston groove 74 to be discharged to the outside.

[0045] Through the arrangement of the above structure, when the airflow moves along the exhaust groove 62, the impeller 73 will be driven to rotate, and the absorbent sponge wrapped on the surface of the impeller 73 will absorb the moisture carried in the airflow to prevent water vapor from entering the charging pile body 1. When the impeller 73 rotates, the magnetic plate 731 and the piston plate 741 will intermittently repel each other. When the two are in the repulsive area, the piston plate 741 will retract into the piston groove 74, thereby compressing the gas in the piston groove 74 and opening the one-way valve in the air pushing groove 751, so that the gas in the piston groove 74 is discharged to the outside. Then, when the magnetic plate 731 and the piston plate 741 are separated from the repulsive area, the piston plate 741 will be reset under the rebound action of the reset spring 742, thereby A negative pressure suction force is generated in 74, thereby opening the one-way valve in the air extraction groove 75, allowing the gas in the negative pressure box 7 to enter the piston groove 74. This reciprocating process will gradually discharge the gas in the negative pressure box 7 to form a negative pressure cavity. When charging is completed, when the charging gun 3 is inserted back into the storage groove 31, the trigger rod 72 will be squeezed to make the trigger rod 72 retract into the negative pressure box 7, and finally the adsorption groove 722 will be connected with the negative pressure box 7. At this time, the negative pressure suction force in the negative pressure box 7 will be transmitted along the adsorption groove 722, the small cross groove 76 and the large cross groove 761, so that the airflow at the port of the charging gun 3 moves rapidly into the negative pressure box 7, thereby sucking away the water vapor, dust, etc. attached to the port of the charging gun 3, effectively improving the cleanliness of the port of the charging gun 3 and the service life of the port of the charging gun 3.

[0046] Reference Figure 1-Figure 3 Among them, an inspection groove is provided at the bottom of the empty slot of the charging pile body 1, and the inspection groove is connected with the cooling groove 6 and the driving compartment 66, and a sealing plate 8 is fixedly connected in the inspection groove by bolts. The removable sealing plate 8 can facilitate the maintenance and replacement of the structures in the cooling groove 6 and the driving compartment 66, thereby improving the convenience of use and maintenance.

[0047] Reference Figure 1-Figure 10 In the present invention, when charging the car, the charging gun 3 is pulled out from the storage slot 31, and then the charging cable 2 is pulled. After the charging cable 2 is adjusted to a suitable length, the locking rod 441 is rotated so that the end of the locking rod 441 is pressed against the outer wall of the charging cable 2 to complete the locking of the charging cable 2, thereby ensuring the stability of the charging cable 2 during the charging process. Then, the charging gun 3 can be plugged into the charging port of the car for charging.

[0048] During the charging process, the driving motor 661 is turned on synchronously, and the transmission relationship of the gear set 662 is used to drive the driven shaft 651 to rotate, thereby driving the linkage ring 652 and the exhaust fan blades 64 to rotate. When the exhaust fan blades 64 rotate, a suction effect will be generated on the side of the cooling tank 6 close to the air inlet slot 61, so that the external airflow passes through the air inlet filter 68 and enters the cooling tank 6 along the air inlet slot 61 to achieve preliminary filtration of the airflow. In this process, with the action of the vibration spring 682 and the wind resistance, the air inlet filter 68 will be reciprocated. Rocking, so that the dust attached to the windward surface of the air inlet filter 68 is shaken off, ensuring the use effect of the air inlet filter 68, and on the side close to the exhaust slot 62 A thrust effect will be generated, causing the airflow to enter the collecting groove 4 along the exhaust groove 62 and finally be discharged from the air outlet groove 63, thereby accelerating the airflow exchange speed inside the charging pile body 1, achieving ventilation and heat dissipation, and improving the protection effect of the electrical equipment and components inside the charging pile body 1. When the exhaust fan blades 64 rotate, they will contact the water flow in the cooling groove 6 and carry the water flow to rotate, thereby generating a layer of water mist film around the exhaust fan blades 64. At this time, the airflow will pass through this layer of water mist film to achieve water washing of the airflow, effectively reducing the temperature of the airflow, and intercepting the dust carried in the airflow, thereby improving the cleanliness of the airflow, reducing the wear and erosion of the dust on the electrical equipment and components inside the charging pile body 1, and improving the protection effect. At the same time, the linkage ring 652 will also drive the pumping blades 655 to rotate, so that a diversion effect is generated in the cavities of the driven shaft 651 and the linkage ring 652, so that the water in the cooling trough 6 flows along the pumping trough 653, the cavity of the driven shaft 651, the cavity of the linkage ring 652 and the drainage trough 654 into the filter box 67, and after being filtered by the filter residue net 671, it is discharged back into the cooling trough 6 from the output end of the drainage trough 654, so as to collect the dust intercepted in the water flow, which improves the neatness of the water flow and reduces the friction of the dust on the pumping blades 655, thereby ensuring the durability of the pumping blades 655.

[0049] When the airflow moves along the exhaust groove 62, it will push the impeller 73 to rotate, and the water-absorbing sponge wrapped on the surface of the impeller 73 will absorb the moisture carried in the airflow to prevent water vapor from entering the charging pile body 1. When the impeller 73 rotates, the magnetic plate 731 and the piston plate 741 will intermittently repel each other. When the two are in the repulsive area, the piston plate 741 will retract into the piston groove 74, thereby compressing the gas in the piston groove 74 and opening the one-way valve in the air pushing groove 751, so that the gas in the piston groove 74 is discharged to the outside. Then, when the magnetic plate 731 is rotated, the piston plate 741 will retract into the piston groove 74, thereby compressing the gas in the piston groove 74 and opening the one-way valve in the air pushing groove 751, so that the gas in the piston groove 74 is discharged to the outside. After the charging is completed, the charging gun 3 is aligned and inserted back into the receiving groove 31. As the charging gun 3 is inserted, the extrusion block 53 contacts and squeezes the clamping block 5, so that the clamping block 5 is pushed upward and the clamping spring 52 is compressed, and finally the clamping block 5 is clamped. Under the rebound effect of the holding spring 52, the charging gun 3 will be clamped and fixed in the storage groove 31, which ensures the stability of the charging gun 3 and makes it convenient to take the charging gun 3. When the charging gun 3 moves to the innermost side of the storage groove 31, the trigger rod 72 will be squeezed to make the trigger rod 72 retract into the negative pressure box 7. Finally, when the charging gun 3 is inserted, the adsorption groove 722 will be connected with the negative pressure box 7. At this time, the negative pressure suction force in the negative pressure box 7 will be transmitted along the adsorption groove 722, the small cross groove 76 and the large cross groove 761, so that the airflow at the port of the charging gun 3 moves quickly into the negative pressure box 7, thereby The water vapor, dust and the like attached to the port of the charging gun 3 are sucked away, which effectively improves the cleanliness of the port of the charging gun 3 and increases the service life of the port of the charging gun 3; finally, the locking rod 441 is rotated in the opposite direction to release the lock of the charging line 2. At this time, under the rebound action of the retraction spring 42, the retraction rod 41 will pull the charging line 2 to reset and move, so that the excessively long part of the charging line 2 is stored in the retraction groove 4, and the outer end part of the charging line 2 will fit on the empty groove wall of the charging pile body 1, without the need for manual storage and winding, which effectively reduces the entanglement, falling and wear of the charging line 2 and increases the service life of the charging line 2.
