Description

Technical Field

[0001] This invention relates to the field of charging pile technology, specifically to an installation structure and method for a DC charging pile embedded in the side wall of an integrated energy storage box. Background Technology

[0002] Installing charging piles inside energy storage boxes is an integrated energy storage and charging solution that integrates energy storage batteries, charging modules, and power distribution systems within the box. It does not require a large additional area and is suitable for scenarios such as urban areas and highway service areas where land resources are scarce.

[0003] For example, a new energy charging pile protection device with announcement number CN118024920B includes a first housing, a mounting plate, a second housing, and a cable winding and unwinding assembly. The mounting plate is located inside the first housing, and a lifting assembly is connected between the mounting plate and the bottom of the first housing. The lifting assembly is used to adjust the height of the mounting plate inside the first housing. The second housing is fixedly mounted on the mounting plate, and a power supply assembly is fixedly mounted inside the second housing. The cable winding and unwinding assembly is provided inside the second housing and is connected to the power supply assembly. The cable winding and unwinding assembly is used to connect the power supply assembly and the charging assembly. The charging assembly is installed on the top of the second housing, and a locking assembly is installed on the top of the first housing. By adjusting the cable winding and unwinding assembly, the lifting assembly, and the locking assembly through a control module, the charging pile can be sealed and protected when not in use, and the charging cable can be stably wound and unwound when the charging pile is in use, thereby increasing the service life of the charging pile.

[0004] Embedded DC charging piles are a new type of charging solution that tightly integrates equipment with the building structure. They eliminate the need for a separate external enclosure and can be embedded in walls, the edges of energy storage boxes, and other locations, significantly reducing footprint. Through optimized integrated power conversion design, their energy conversion efficiency is more than 15% higher than traditional charging piles, reducing energy loss during charging. However, when the charging pile is embedded into the energy storage box, uneven fixing pressure at the embedding port may lead to unstable fixing or poor sealing, affecting the installation stability and normal use of the charging pile. Furthermore, the embedded, enclosed structure restricts natural airflow, requiring additional heat dissipation structures to address the heat dissipation problem. For high-power charging piles, liquid cooling is generally used. However, existing liquid cooling structures are not conducive to controlling the flow rate of cooling water. When the cooling water flow rate is too fast, it cannot stay at the heat dissipation location of the charging pile for a sufficient time, hindering heat exchange and reducing the heat dissipation effect of high-power charging piles, thus affecting normal charging operation.

[0005] Therefore, an installation structure and method for embedded DC charging piles on the side wall of an integrated energy storage box are proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an installation structure and method for an embedded DC charging pile on the side wall of an integrated energy storage box, so as to solve the problem that the existing liquid cooling heat dissipation structure is not convenient to control the flow rate of cooling water, which will reduce the heat dissipation effect on high-power charging piles.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an installation structure for an embedded DC charging pile in the side wall of an integrated energy storage box, comprising an outer box, a charging pile body and a charging panel, wherein a box door is hinged to one side of the inner side of the outer box; Also includes: A cooling assembly is provided on the other side of the interior of the outer casing, and a mounting assembly is provided on the outer side of the outer casing; The cooling assembly includes a heat dissipation unit and a drive unit. The heat dissipation unit is located on the outside of the charging pile body and includes a circulating water pipe and two exhaust fans that slide in a vertical direction. The circulating water pipe is in contact with the outside of the charging pile body and is used for heat exchange treatment of the charging pile body. The drive unit includes two adjusting discs rotatably installed inside the circulating water pipe. As the exhaust fan moves up and down, it drives the adjusting discs to deflect, thereby obstructing the cooling water inside the circulating water pipe and extending the heat exchange time of the cooling water. The mounting assembly includes two sealing elements symmetrically mounted on the outside of the outer casing. The sealing elements are movable in the vertical direction and are used to seal the mounting gap between the charging panel and the outer casing, and to press and fix the charging panel.

[0008] Preferably, a left air inlet is provided on the lower part of one side of the outer casing, and an air outlet is provided on the upper part of one side of the outer casing. An isolation box is also fixedly installed inside the outer casing. The isolation box includes two symmetrically arranged boxes. The charging pile body is located between the two isolation boxes. The charging panel and the charging pile body are integrally fixed. The heat dissipation unit also includes a pump and a cooler fixedly installed on the bottom surface of the outer casing. One end of the circulating water pipe is connected to the outlet end of the pump, and the other end of the circulating water pipe is connected to the inlet end of the cooler.

[0009] By adopting the above technical solution, the exhaust fan assists in the heat dissipation of the charging pile body and circulating water pipe inside the isolation box. When the sliding seat moves, it drives the contact plate on the outside of the circulating water pipe to deflect from top to bottom. The contact plate drives the sleeve on the outside of the circulating water pipe to rotate, and finally drives the adjusting plate inside the circulating water pipe to rotate. This increases the resistance to the flow of cooling water, reduces the flow rate of cooling water, prolongs the heat exchange time of cooling water on the outside of the charging pile body, and ensures that the cooling water is fully utilized for heat dissipation.

[0010] Preferably, a return pipe is fixedly installed between the inlet end of the pump body and the outlet end of the cooler. Two vertical plates are vertically fixedly connected to the front and rear sides of the charging pile body. The circulating water pipe is fixedly connected to the vertical plates. An upper plate and a lower plate are fixedly connected to the inner wall of the isolation box from top to bottom. A servo motor is fixedly installed on the top of the upper plate. A lead screw is fixedly connected to the servo motor through the upper plate. A guide rod is fixedly connected between the upper plate and the lower plate.

[0011] By adopting the above technical solution, the pump body pumps cooling water into the circulating water pipe, the cooling water cools the charging pile body, and then flows into the cooler for further cooling. The cooling water is then drawn back into the pump body through the return pipe, thus achieving circulating water cooling heat dissipation.

[0012] Preferably, a sliding seat is threaded to the outer side of the lead screw, and the two exhaust fans are respectively located on the front and rear sides of the charging pile body. The sliding seat is slidably connected to the guide rod through a fixing strip, and the exhaust fan is fixedly installed in the middle of the fixing strip. A pressure plate is fixedly connected to the side of the sliding seat near the charging pile body. A sleeve is rotatably connected to the outer side of the circulating water pipe located on the front and back of the charging pile body. Both ends of the sleeve are fixedly connected to torsion springs, and the two torsion springs are fixedly connected to the vertical plates on both sides on the side away from the sleeve.

[0013] By adopting the above technical solution, when the sliding seat moves, the pressure plate will squeeze the contact plate, causing the contact plate to deflect. The contact plate drives the sleeve to rotate, and the sleeve acts on the torsion spring.

[0014] Preferably, a contact plate is fixedly connected to the side of the sleeve near the sliding seat, an inner ring body is fixedly connected to the inner side of the sleeve, an inner plate and an inner rod are fixedly connected inside the inner ring body, two adjusting discs are fixedly connected to the two ends of the inner rod respectively, two fixed discs are fixedly connected inside the circulating water pipe, the two adjusting discs abut against the fixed discs on both sides respectively, a semi-circular groove one is opened inside the adjusting disc, a semi-circular groove two is opened inside the fixed disc, and the semi-circular groove one and the semi-circular groove two are initially in an overlapping state.

[0015] By adopting the above technical solution, when the sleeve and contact plate deflect, they will also drive the inner ring and inner plate to rotate. The inner plate will drive the inner rod and adjusting plate to rotate, which will reduce the overlap area of ​​semicircular groove one and semicircular groove two, thereby increasing the obstruction to the flow of cooling water.

[0016] Preferably, the mounting assembly includes two horizontal bars that are fixedly connected in parallel to one side of the outer casing. A screw is rotatably connected inside the horizontal bars, and a sliding sleeve is threadedly connected to the outside of the screw. Two side plates are symmetrically fixedly connected to the outside of the sliding sleeve. A support plate is rotatably connected to the bottom of the side plates, and a base block is rotatably connected to the bottom of the support plate.

[0017] By adopting the above technical solution, the rotation of the screw will drive the sliding sleeve to move, the sliding sleeve will drive the expansion plate and the bottom block to move, the bottom block will drive the crossbar and the sealing element to move, and the sealing element will fit into the outer casing, so that the upper and lower sealing elements are close and tightly fitted.

[0018] Preferably, the top of the seal is fixedly connected to two fixing blocks, and a crossbar is fixedly connected between the two fixing blocks. The bottom block is slidably connected to the crossbar. A spring is sleeved on the outside of the fixing block, and the two ends of the spring are fixedly connected to the two bottom blocks respectively. The bottom block is in contact with the seal.

[0019] By adopting the above technical solution, when the side plate moves, it will drive the expansion plate to unfold to both sides. The expansion plate will drive the bottom block to slide on the outside of the crossbar. The two bottom blocks stretch the spring to keep the pressure of the seal stable when it is pressed.

[0020] Preferably, a locking rod is fixedly connected to the side of the sealing element away from the horizontal bar; slots are provided at the top and bottom of the charging panel; the locking rod engages with the slots; an L-shaped plate is fixedly connected to the middle of one side of the outer casing; the sealing element is slidably connected to the L-shaped plate; a right air inlet is provided at the lower part of the other side of the outer casing; an air outlet is fixedly installed on the top of the outer casing; a ventilation fan is fixedly installed inside the air outlet; a filter screen is fixedly connected to the top surface of the air outlet; a partition is vertically fixedly connected to the middle of the interior of the outer casing; and a charging gun is detachably installed on the outside of the charging panel.

[0021] By adopting the above technical solution, the card rod is pressed into the card slot, and the L-shaped plate seals the connection between the two sealing parts, thus achieving a seal at the connection of the charging panel.

[0022] A method for using an embedded DC charging pile installation structure on the side wall of an integrated energy storage box, comprising the following steps: Step 1: By fixing the charging pile body to the inner wall of the outer casing with bolts, the two seals are located at the top and bottom of the charging panel respectively. By rotating the screw, the upper and lower seals are brought close together and pressed tightly, thus sealing the connection of the charging panel. The side plate will drive the expansion plate to unfold to both sides, keeping the pressure of the seals stable when they are pressed. Step 2: By starting the pump and cooler, the pump pumps cooling water into the circulating water pipe to achieve circulating water cooling of the charging pile body. The sliding seat and exhaust fan move up and down to assist in cooling the charging pile body and circulating water pipe inside the isolation box. Step 3: When the sliding seat moves, the pressure plate will squeeze the contact plate, causing the contact plate to deflect. The overlapping area of ​​semicircular groove one and semicircular groove two will decrease, thereby increasing the resistance to the flow of cooling water, reducing the flow rate of cooling water, and prolonging the heat exchange time of cooling water on the outside of the charging pile body. When the pressure plate separates from the contact plate, the torsion spring drives the sleeve and the adjusting plate to rotate, so that the flow rate of cooling water is restored, and the auxiliary air circulation is coordinated with the exhaust fan.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting up a cooling component, and utilizing the cooperation of components such as the exhaust fan and sliding seat in the heat dissipation unit, the position of the exhaust fan can be easily adjusted up and down, thereby assisting the downward entry and upward exit of gas inside the isolation box, assisting in the heat dissipation of the charging pile body and circulating water pipe inside the isolation box, and improving the heat dissipation effect of the charging pile body. At the same time, when the sliding seat in the adjustment unit moves, it will drive the contact plate on the outside of the circulating water pipe to deflect from top to bottom. The contact plate drives the sleeve on the outside of the circulating water pipe to rotate, and finally drives the adjustment plate inside the circulating water pipe to rotate, thereby increasing the resistance to the flow of cooling water, reducing the flow rate of cooling water, extending the heat exchange time of cooling water on the outside of the charging pile body, and maintaining the full heat dissipation utilization of cooling water. Combined with the auxiliary exhaust circulation of the exhaust fan, efficient heat dissipation and full heat dissipation treatment of the charging pile body are achieved, reducing the failure caused by the overheating of the charging pile body, and facilitating the normal use of the charging pile body. The specific details are as follows: By incorporating a cooling system, after the charging pile body is installed on the side wall of the outer casing, the pump and cooling machine are activated. The pump pumps cooling water into the circulating water pipe, cooling the charging pile body. The water then flows into the cooling machine for further cooling. The cooling water is then drawn back into the pump body through the return pipe, achieving circulating water cooling. Simultaneously, the servo motor and exhaust fan are activated. The servo motor drives the lead screw to rotate, causing the sliding seat and exhaust fan to move up and down. This assists in the downward flow and upward flow of gas inside the isolation box, aiding in the cooling of the charging pile body and circulating water pipes inside the isolation box, improving the heat dissipation effect on the charging pile body. Furthermore, as the sliding seat moves, the pressure plate presses against the contact plate, ensuring proper contact... When the plate deflects, the contact plate drives the sleeve to rotate. The sleeve acts on the torsion spring, and the sleeve also drives the inner ring body and inner plate to rotate. The inner plate drives the inner rod and adjusting plate to rotate, which reduces the overlapping area of ​​semicircular groove one and semicircular groove two, thereby increasing the resistance to the flow of cooling water, reducing the flow rate of cooling water, and extending the heat exchange time of cooling water on the outside of the charging pile body. This ensures that the cooling water is fully utilized for heat dissipation. When the pressure plate separates from the contact plate, the torsion spring drives the sleeve and adjusting plate to rotate, which restores the flow rate of cooling water. Combined with the auxiliary air circulation of the exhaust fan, this achieves efficient heat dissipation and full heat dissipation of the charging pile body, reducing malfunctions caused by overheating of the charging pile body and facilitating the normal use of the charging pile body. By setting up the installation components, during the installation of the charging pile body, the charging pile body is first fixed to the inner wall of the outer casing with bolts. At this time, the charging panel passes through the square groove on the outer casing. The two seals are located at the top and bottom of the charging panel respectively. By rotating the screw, the screw drives the sliding sleeve to move, the sliding sleeve drives the expansion plate and the bottom block to move, and the bottom block drives the crossbar and the seals to move. The seals fit into the outer casing, so that the upper and lower seals are close and tight. The clamping rod is pressed into the clamping groove, and the L-shaped plate seals the connection of the two seals, thus sealing the connection of the charging panel. The side plate will drive the expansion plate to unfold to both sides, and the expansion plate will drive the bottom block to slide on the outside of the crossbar. The two bottom blocks stretch springs to keep the pressure of the seals stable when they are pressed, which improves the sealing and stability of the charging panel installation. By setting up a right air inlet, an air outlet, a ventilation fan, a filter, a partition, and an isolation box, the ventilation fan draws air from the box door. The gas enters through the right air inlet and exits through the air outlet. The filter plays a filtering role. The partition isolates the charging pile body from the box door. The isolation box protects the charging pile body. When the exhaust fan is working, the gas enters from the left air inlet and exits from the air outlet, which facilitates auxiliary heat dissipation for the charging pile body and the circulating water pipe.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-3 The present invention provides a technical solution: an installation structure for an embedded DC charging pile in the side wall of an integrated energy storage box, including an outer box 1, a charging pile body 5 and a charging panel 14, wherein a box door 2 is hinged to one side of the inner side of the outer box 1.

[0028] like Figure 1 and Figures 3-11 As shown, a cooling assembly 6 is provided on the other side of the interior of the outer casing 1. The cooling assembly 6 includes a heat dissipation unit and a drive unit. The heat dissipation unit is located on the outside of the charging pile body 5 and includes a circulating water pipe 62 and two exhaust fans 612 that slide in the vertical direction. The circulating water pipe 62 is attached to the outside of the charging pile body 5 and is used for heat exchange treatment of the charging pile body 5.

[0029] A left air inlet 3 is provided on the lower part of one side of the outer casing 1, and an air outlet 4 is provided on the upper part of one side of the outer casing 1. An isolation box 13 is also fixedly installed inside the outer casing 1. The isolation box 13 includes two symmetrical ones, which are fixed to each other by bolts. The charging pile body 5 is located between the two isolation boxes 13. The charging panel 14 and the charging pile body 5 are fixed together for easy removal and use later.

[0030] The heat dissipation unit also includes a pump body 61 and a cooler 64 fixedly installed on the bottom surface of the outer casing 1. One end of the circulating water pipe 62 is connected to the outlet end of the pump body 61, and the other end of the circulating water pipe 62 is connected to the inlet end of the cooler 64. The cooler 64 is used to cool the cooling water and maintain efficient heat dissipation for the charging pile body 5.

[0031] A return pipe 65 is fixedly installed between the inlet end of the pump body 61 and the outlet end of the cooler 64. Two vertical plates 63 are vertically fixedly connected to the front and rear sides of the charging pile body 5. The circulating water pipe 62 is fixedly connected to the vertical plates 63. An upper plate 66 and a lower plate 67 are fixedly connected to the inner wall of the isolation box 13 from top to bottom. A servo motor 68 is fixedly installed on the top of the upper plate 66. A lead screw 69 is fixedly connected to the servo motor 68 through the upper plate 66. A guide rod 610 is fixedly connected between the upper plate 66 and the lower plate 67.

[0032] The outer thread of the lead screw 69 is connected to the sliding seat 611. Two exhaust fans 612 are located on the front and rear sides of the charging pile body 5 respectively. When the exhaust fan 612 is working, it will draw air upward. The external air enters the isolation box 13 through the left air inlet 3 and is then discharged through the air outlet 4, forming a heat dissipation cycle.

[0033] The sliding seat 611 is slidably connected to the guide rod 610 via a fixing strip. The exhaust fan 612 is fixedly installed in the middle of the fixing strip. A pressure plate 613 is fixedly connected to the side of the sliding seat 611 near the charging pile body 5. A sleeve 614 is rotatably connected to the outside of the circulating water pipe 62 located on the front and back of the charging pile body 5. Torsion springs 615 are fixedly connected to both ends of the sleeve 614. The side of the two torsion springs 615 away from the sleeve 614 is fixedly connected to the two vertical plates 63 on both sides. The torsion springs 615 are used to assist the rotation and reset of the sleeve 614.

[0034] The drive unit includes two adjusting discs 620 that are rotatably installed inside the circulating water pipe 62. As the exhaust fan 612 moves up and down, it drives the adjusting discs 620 to deflect, thereby obstructing the cooling water inside the circulating water pipe 62 and extending the heat exchange time of the cooling water.

[0035] A contact plate 616 is fixedly connected to the side of the sleeve 614 near the sliding seat 611. An inner ring body 617 is fixedly connected to the inner side of the sleeve 614. An inner plate 618 and an inner rod 619 are fixedly connected inside the inner ring body 617. Two adjusting discs 620 are fixedly connected to the two ends of the inner rod 619 respectively. Two fixed discs 621 are fixedly connected inside the circulating water pipe 62. The two adjusting discs 620 are pressed against the fixed discs 621 on both sides respectively. A semi-circular groove 622 is opened inside the adjusting disc 620. A semi-circular groove 623 is opened inside the fixed disc 621. The semi-circular groove 622 and the semi-circular groove 623 are initially in an overlapping state.

[0036] Example 1: As Figures 3-11 As shown, after the charging pile body 5 is installed on the side wall of the outer casing 1, the pump body 61 and the cooler 64 are started. The pump body 61 pumps cooling water into the circulating water pipe 62, and the cooling water cools the charging pile body 5. Then it flows into the cooler 64 for further cooling. The cooling water is drawn back into the pump body 61 through the return pipe 65 to achieve circulating water cooling. At the same time, the servo motor 68 and the exhaust fan 612 are started. The servo motor 68 drives the lead screw 69 to rotate, causing the sliding seat 611 and the exhaust fan 612 to move up and down. This helps the gas inside the isolation box 13 to enter from the bottom and exit from the top, which helps to cool the charging pile body 5 and the circulating water pipe 62 inside the isolation box 13 and improves the heat dissipation effect of the charging pile body 5.

[0037] Simultaneously, when the sliding seat 611 moves, the pressure plate 613 will squeeze the contact plate 616, causing the contact plate 616 to deflect. The contact plate 616 drives the sleeve 614 to rotate. The sleeve 614 acts on the torsion spring 615. The sleeve 614 will also drive the inner ring body 617 and the inner plate 618 to rotate. The inner plate 618 drives the inner rod 619 and the adjusting plate 620 to rotate, which reduces the overlap area of ​​the semicircular groove one 622 and the semicircular groove two 623, thereby increasing the resistance to the flow of cooling water, reducing the flow rate of cooling water, extending the heat exchange time of cooling water on the outside of the charging pile body 5, and maintaining the full heat dissipation utilization of cooling water.

[0038] When the pressure plate 613 separates from the contact plate 616, the torsion spring 615 drives the sleeve 614 and the adjusting plate 620 to rotate, which restores the cooling water flow rate. Combined with the auxiliary air circulation of the exhaust fan 612, efficient heat dissipation and sufficient heat dissipation treatment of the charging pile body 5 are achieved, reducing the failure caused by the overheating of the charging pile body 5 and facilitating the normal use of the charging pile body 5.

[0039] like Figure 1 and Figures 12-14As shown, an installation component 7 is provided on the outer side of the outer casing 1. The installation component 7 includes two sealing members 77 that are symmetrically installed on the outer side of the outer casing 1. The sealing members 77 can move in the vertical direction to seal the installation gap between the charging panel 14 and the outer casing 1, and to press and fix the charging panel 14.

[0040] The mounting assembly 7 includes two horizontal bars 71 that are fixedly connected in parallel to one side of the outer housing 1. A screw 72 is rotatably connected inside the horizontal bar 71. A sliding sleeve 73 is threadedly connected to the outside of the screw 72. Two side plates 74 are symmetrically fixedly connected to the outside of the sliding sleeve 73. A support plate 75 is rotatably connected to the bottom of the side plate 74. A base block 76 is rotatably connected to the bottom of the support plate 75.

[0041] The top of the seal 77 is fixedly connected to two fixing blocks 78, and a crossbar 79 is fixedly connected between the two fixing blocks 78. The bottom block 76 is slidably connected to the crossbar 79. A spring 710 is sleeved on the outside of the fixing blocks 78. The two ends of the spring 710 are fixedly connected to the two bottom blocks 76 respectively. The bottom blocks 76 are in contact with the seal 77.

[0042] A locking rod 711 is fixedly connected to the side of the seal 77 away from the horizontal bar 71. The top and bottom of the charging panel 14 are provided with slots 712. The locking rod 711 is engaged with the slots 712. An L-shaped plate 713 is fixedly connected to the middle of one side of the outer casing 1. The seal 77 is slidably connected to the L-shaped plate 713. Two L-shaped plates 713 are symmetrically arranged. The two L-shaped plates 713 limit the seal 77 so that the seal 77 will not be horizontally misaligned.

[0043] A right air inlet 8 is provided on the lower part of the other side of the outer casing 1. An air outlet 9 is also fixedly installed on the top of the outer casing 1. A ventilation fan 10 is fixedly installed inside the air outlet 9. A filter screen 11 is fixedly connected to the top surface of the air outlet 9. A partition 12 is vertically fixedly connected in the middle of the interior of the outer casing 1. A charging gun 15 is detachably installed on the outside of the charging panel 14.

[0044] Example 2: Figures 12-14 As shown, when installing the charging pile body 5, the charging pile body 5 is first fixed to the inner wall of the outer casing 1 with bolts. At this time, the charging panel 14 passes through the square groove on the outer casing 1. The two sealing pieces 77 are located at the top and bottom of the charging panel 14 respectively. By rotating the screw 72, the screw 72 drives the sliding sleeve 73 to move. The sliding sleeve 73 drives the expansion plate 75 and the bottom block 76 to move. The bottom block 76 drives the crossbar 79 and the sealing piece 77 to move. The sealing piece 77 fits into the outer casing 1, so that the upper and lower sealing pieces 77 are close and tight.

[0045] The sealing element 77 drives the locking rod 711 to press into the locking groove 712. The L-shaped plate 713 seals the connection between the two sealing elements 77, thus sealing the connection of the charging panel 14. The side plate 74 drives the expansion plate 75 to unfold to both sides. The expansion plate 75 drives the bottom block 76 to slide on the outside of the crossbar 79. The two bottom blocks 76 stretch the spring 710 to keep the pressure of the sealing element 77 stable when it is pressed, thus improving the sealing and stability of the charging panel 14 installation.

[0046] By setting up a right air inlet 8, an air outlet 9, a ventilation fan 10, a filter 11, a partition 12, and an isolation box 13, the ventilation fan 10 draws air from the box door 2, the gas enters through the right air inlet 8 and is discharged from the air outlet 9, the filter 11 plays a filtering role, the partition 12 isolates the charging pile body 5 and the box door 2, and the isolation box 13 protects the charging pile body 5.

[0047] Working principle: When using this device, firstly, as... Figures 1-14 As shown, the charging pile body 5 is fixed to the inner wall of the outer casing 1 with bolts. Two sealing pieces 77 are located at the top and bottom of the charging panel 14, respectively. By rotating the screw 72, the two sealing pieces 77 are brought closer together and pressed tightly. The locking rod 711 is pressed into the locking groove 712, which achieves the sealing of the connection of the charging panel 14. The side plate 74 will drive the expansion plate 75 to unfold to both sides, keeping the pressure of the sealing pieces 77 stable when pressed, thus improving the sealing and stability of the charging panel 14 installation. By starting the pump body 61 and the cooler 64, the pump body 61 pumps cooling water into the circulating water pipe 62 to achieve circulating water cooling of the charging pile body 5. The sliding seat 611 and the exhaust fan 612 reciprocate up and down. The movement of the sliding seat 611 assists in the cooling of the charging pile body 5 and the circulating water pipe 62 inside the isolation box 13. At the same time, when the sliding seat 611 moves, the pressure plate 613 will squeeze the contact plate 616, causing the contact plate 616 to deflect. The contact plate 616 drives the sleeve 614 to rotate. The sleeve 614 acts on the torsion spring 615, reducing the overlap area of ​​the semi-circular groove 1 622 and the semi-circular groove 2 623, thereby increasing the resistance to the flow of cooling water, reducing the flow rate of cooling water, and prolonging the heat exchange time of cooling water on the outside of the charging pile body 5. When the pressure plate 613 separates from the contact plate 616, the torsion spring 615 drives the sleeve 614 and the adjusting plate 620 to rotate, so that the flow rate of cooling water is restored, and then the exhaust fan 612 assists in the air extraction circulation.
