Description

Technical Field

[0001] The present invention relates to the field of new energy vehicle charging piles, and in particular to an intelligent new energy vehicle charging pile. Background Art

[0002] New energy vehicles (NEVs) use unconventional fuels as their power source, or utilize conventional fuels but employ novel onboard power units, integrating advanced technologies in vehicle power control and drive. These vehicles feature advanced technical principles, new technologies, and new structures. New energy vehicles include hybrid electric vehicles (HEVs), battery electric vehicles (BEVs), fuel cell vehicles (FCEVs), hydrogen engine vehicles, gas vehicles, and alcohol-ether vehicles. Due to their different driving forces, NEVs are more reliant on charging stations than conventional vehicles.

[0003] Currently, most public charging stations are installed outdoors. However, these stations are susceptible to weather conditions. High temperatures can cause short circuits inside the stations, and rainy weather can lead to water ingress and damage. Therefore, a smart charging station for new energy vehicles has been proposed. Summary of the Invention

[0004] The present invention aims to solve the technical problems that short circuits are easily caused inside the charging pile due to excessive temperature, and water is easily infiltrated into the charging pile on rainy days, causing damage to the charging pile, and provides an intelligent new energy vehicle charging pile.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] An intelligent new energy vehicle charging pile, comprising a main body, a protective mechanism, a heat dissipation mechanism and a sealing mechanism;

[0007] A mounting seat is fixedly provided at the bottom of the main body, a charging module is provided inside the main body, a cabinet door is provided on the front side wall of the main body, the left edge of the cabinet door is rotatably connected to the main body, a switch is provided in the middle of the right side of the cabinet door, a control screen is fixedly provided on the upper part of the cabinet door, and the control screen is electrically connected to the charging module, charging interfaces are fixedly provided in the middle of both side walls of the main body, the input end of the charging interface is electrically connected to the charging module, a charging gun is detachably provided on the outside of the charging interface, a handle is fixedly provided on the outer edge of the charging gun, a connecting line is connected to the bottom input end of the charging gun, and the input end of the connecting line is electrically connected to the charging module, the protective mechanism is provided at the top of the main body, the heat dissipation mechanism is provided on both side walls of the main body, and the sealing mechanism is provided inside the main body. When using the charging pile, unplug the charging gun from the charging interface and insert it into the charging port of the new energy vehicle. The charging parameters can be controlled through the control screen. When maintenance is required, the switch can be turned to open the cabinet door for easy maintenance. The heat dissipation mechanisms on both sides can automatically dissipate heat when the temperature inside the main body is too high. The protective mechanism and sealing mechanism can protect and seal the main body on rainy days to prevent water from entering the main body and causing a short circuit.

[0008] Furthermore, the protective mechanism includes a liquid collection tank, a lifting platform is connected between the bottom of the liquid collection tank and the top of the main body, a filter plate is fixedly installed on the top of the liquid collection tank, a pair of slopes are symmetrically provided on the top of the liquid collection tank, the connection point of the pair of slopes protrudes from the two side edges of the liquid collection tank, the cross-sectional shape of the filter plate matches the shape of the top of the liquid collection tank, and liquid outlet holes are opened on both sides of the bottom of the liquid collection tank. On rainy days, rainwater enters the interior of the liquid collection tank, and the filter plate can prevent external debris from rolling down the filter plate, thereby preventing external debris from entering the interior of the liquid collection tank. After entering the liquid collection tank, rainwater is discharged through the liquid outlet holes.

[0009] Furthermore, the lifting platform includes a fixed end and a movable end, the top of the movable end being fixedly connected to the bottom of the liquid sump, the bottom of the fixed end being fixedly connected to the top of the main body, the movable end being slidably mounted on the outside of the fixed end, the interiors of the fixed end and the movable end being hollow, a pair of first telescopic rods being symmetrically disposed inside the fixed end and the movable end, the tops of the first telescopic rods being fixedly connected to the bottom of the liquid sump, the bottoms of the first telescopic rods being fixedly connected to the top of the main body, the first telescopic rods being perpendicularly disposed to the bottom of the liquid sump and the top of the main body, and a first return spring being disposed around the outside of the first telescopic rods. When rainfall is heavy, the amount of water entering the liquid sump is greater than the amount of water discharged, causing the gravity of the liquid sump to increase, and the movable end at the top of the lifting platform being pushed downward and beginning to move downward. At this time, the first telescopic rods inside the lifting platform shorten, compressing the first return spring thereof, generating an upward thrust on the liquid sump. When rainfall is light, the liquid sump returns to its original position under the elastic force of the first return spring.

[0010] Furthermore, a plurality of vertical rods are vertically arranged at the four edges of the bottom of the liquid accumulation tank, and the bottom ends of the vertical rods extend through the top of the main body to the interior of the main body. Connecting shafts are provided on the four edges of the top of the main body, and an outer sleeve is provided on the outside of the connecting shaft for rotation. A pair of first side panels are symmetrically provided on the outside of the outer sleeve on the left and right sides of the connecting shaft, and a pair of second side panels are symmetrically provided on the outside of the outer sleeve on the front and rear sides of the connecting shaft. A flexible waterproof curtain is connected between the edges of adjacent first side panels and second side panels, and a movable groove is provided at the connection between the outer sleeve and the main body. The bottom height of the vertical rod matches the height of the outer sleeve, and a second telescopic rod is horizontally connected between the bottom end of the vertical rod and the inner middle part of the outer sleeve. When the liquid accumulation tank moves downward, it also drives the vertical rod downward, causing the second telescopic rod connected to the bottom of the vertical rod to rotate downward, driving the outer sleeve connected to the other end of the second telescopic rod to rotate around the connecting shaft away from the main body, thereby causing the first side panel and the second side panel on the top of the main body to open, and at the same time driving the flexible waterproof curtain between the first side panel and the second side panel to open, protecting the main body and preventing rainwater from flowing into the charging port along the outer wall of the main body, causing a short circuit in the charging circuit.

[0011] Furthermore, the heat dissipation mechanism includes heat dissipation holes, which are opened in the middle of the left and right side walls of the main body, and are located on the lower side of the first side panel. A dust screen is fixedly installed inside the heat dissipation hole, and a mounting ring is provided inside the heat dissipation hole. A mounting bracket is fixedly installed on the inner side wall of the mounting ring facing the charging module. The mounting bracket is arranged perpendicular to the mounting ring, and a motor is fixedly installed in the center of the mounting bracket. The heat dissipation holes can dissipate heat from the main body, and the dust screen can prevent external dust from entering the interior of the main body.

[0012] Furthermore, a trigger button is provided at the bottom of the motor, and a bracket is provided at the bottom of the mounting ring. The bracket is perpendicularly arranged to the inner side wall of the main body. A piston rod is fixedly connected to the inner end of the bracket. The piston rod is perpendicularly arranged to the top of the main body. A piston cavity is provided at the inner bottom of the piston rod. A piston is slidably connected to the inner wall of the piston cavity. The bottom of the piston cavity is filled with a thermosensitive liquid. A push rod is fixedly connected to the top of the piston. The push rod is located directly below the trigger button. When the temperature inside the main body is too high, the thermosensitive liquid inside the piston rod expands due to the heat, pushing the piston upward, driving the push rod upward, so that the push rod generates an upward thrust on the trigger button, causing the motor to start.

[0013] Furthermore, the output end of the motor faces the heat dissipation hole, and the output end of the motor is provided with an output shaft, and a plurality of blades are fixedly provided on the outer wall of the inner end of the output shaft, and the blades are located on the inner side of the dustproof net. The outer end of the output shaft passes through the dustproof net and extends to the outside of the heat dissipation hole. A plurality of cleaning rods are vertically provided on the outer side wall of the output shaft, and the length of the cleaning rod is less than the radius of the heat dissipation hole. A plurality of cleaning brushes are fixedly provided on the side of the cleaning rod facing the dustproof net. After the motor is started, the output shaft is driven to rotate, which drives the blades to rotate, thereby generating wind force toward the outside of the heat dissipation hole, so that the heat inside the main body is discharged along the heat dissipation hole, thereby reducing the temperature inside the main body. When the output shaft rotates, the cleaning rod is also driven to rotate, so that the cleaning brush outside the cleaning rod rotates accordingly, thereby cleaning the dustproof net to prevent the dustproof net from being blocked and affecting the heat dissipation effect.

[0014] Furthermore, the sealing mechanism includes a pair of side slides slidably mounted at the bottom of the heat dissipation hole. Side sliding grooves are defined at the junctions between the left and right outer walls of the main body and the edges of the side slides. The length and width of the side slides are both greater than the diameter of the heat dissipation hole. On rainy days, the side slides can seal the heat dissipation hole to prevent splashing water from entering the interior of the main body through the heat dissipation hole.

[0015] Furthermore, third telescopic rods are rotatably connected between the ends of the top edge of the side slide and the bottom edge of the first side panel. The third telescopic rods are respectively located on either side of the heat dissipation hole and are perpendicularly arranged to the top edge of the side slide and the bottom edge of the first side panel. When the second side panel is raised, the third telescopic rods connected to its bottom edge move upward while simultaneously rotating outward around the top edge of the side slide. At this time, the third telescopic rods drive the side slide to slide upward along the side slide groove, thereby sealing the heat dissipation hole.

[0016] Furthermore, a transmission rod is fixedly connected to the inner side wall of the bottom end of the vertical rod, and the transmission rod is arranged in an inverted "L" shape. The bottom end of the transmission rod is vertically connected to a cross rod. A connecting groove is vertically opened on the side wall of the push rod. The other end of the cross rod extends into the interior of the connecting groove. The end of the cross rod away from the transmission rod is slidably connected to the push rod. A second return spring is connected between the end of the cross rod away from the transmission rod and the bottom of the connecting groove. On rainy days, the heat dissipation hole is sealed. At this time, the vertical rod moves downward, driving the transmission rod to move downward therewith, so that the cross rod connected to the bottom of the transmission rod moves downward in the connecting groove until the cross rod moves to the bottom of the connecting groove. Since the downward thrust on the cross rod is much greater than the upward thrust on the push rod at this time, the push rod is fixed, thereby ensuring that the motor is in the off state when the heat dissipation hole is sealed, avoiding energy waste and saving energy.

[0017] Beneficial effects of the present invention:

[0018] 1. The intelligent new energy vehicle charging pile of the present invention is provided with a protective device, so that when the rainfall is heavy on rainy days, the liquid accumulation tank moves downward, and at the same time drives the vertical rod to move downward, so that the second telescopic rod rotatably connected to the bottom of the vertical rod rotates downward, driving the outer sleeve connected to the other end of the second telescopic rod to rotate around the connecting shaft away from the main body, thereby causing the first side panel and the second side panel on the top of the main body to open, and at the same time driving the flexible waterproof curtain between the first side panel and the second side panel to open, thereby protecting the main body and preventing rainwater from flowing into the charging port along the outer wall of the main body and causing a short circuit in the charging circuit.

[0019] 2. The intelligent new energy vehicle charging pile of the present invention is provided with a heat dissipation mechanism. When the temperature inside the main body is too high, the thermally sensitive liquid inside the piston rod expands due to the heat, pushing the piston upward, driving the push rod upward, so that the push rod generates an upward thrust on the trigger button, starting the motor. After the motor starts, it drives the output shaft to start rotating, driving the blades to start rotating, thereby generating wind force toward the outside of the heat dissipation hole, so that the heat inside the main body is discharged through the heat dissipation hole, thereby reducing the temperature inside the main body. When the output shaft rotates, it also drives the cleaning rod to start rotating, causing the cleaning brush outside the cleaning rod to rotate accordingly, thereby cleaning the dust screen, preventing the dust screen from being blocked and affecting the heat dissipation effect.

[0020] 3. The intelligent new energy vehicle charging pile of the present invention is provided with a sealing mechanism. When the second side panel is raised, it drives the third telescopic rod connected to its bottom edge to move upward and rotate outward around the top edge of the side slide. At this time, the third telescopic rod drives the side slide to slide upward along the side slide groove, thereby sealing the heat dissipation hole and preventing splashing water from entering the interior of the main body through the heat dissipation hole.

[0021] 4. The intelligent new energy vehicle charging pile of the present invention is provided with a transmission rod, so that the heat dissipation holes are sealed on rainy days. At this time, the vertical rod moves downward, driving the transmission rod to move downward, so that the cross bar connected to the bottom of the transmission rod moves downward in the connecting groove until the cross bar moves to the bottom of the connecting groove. Since the downward thrust on the cross bar is much greater than the upward thrust on the push rod at this time, the push rod is fixed, thereby ensuring that the motor is in the off state when the heat dissipation holes are sealed, avoiding energy waste and saving energy.

When the charging pile is in use, the charging gun 6 is pulled out from the charging interface 5 and inserted into the charging port of the new energy vehicle. The charging parameters can be controlled through the control screen 9. When maintenance is required, the switch 4 can be turned to open the cabinet door 3 for easy maintenance. The heat dissipation mechanisms on both sides can automatically dissipate heat when the temperature inside the main body 1 is too high. The protective mechanism and sealing mechanism can protect and seal the main body 1 on rainy days to prevent water from entering the main body 1 and causing a short circuit.

[0030] The protective mechanism includes a liquid sump 11, a lifting platform 12 is connected between the bottom of the liquid sump 11 and the top of the main body 1, a filter plate 15 is fixedly provided on the top of the liquid sump 11, a pair of slopes are symmetrically provided on the top of the liquid sump 11, and the connection of the pair of slopes protrudes from the two side edges of the liquid sump 11. The cross-sectional shape of the filter plate 15 matches the shape of the top of the liquid sump 11, and liquid outlet holes 16 are provided on both sides of the bottom of the liquid sump 11. On rainy days, rainwater enters the interior of the liquid sump 11. The filter plate 15 can make external debris roll down along the filter plate 15, preventing external debris from entering the interior of the liquid sump 11. After entering the liquid sump 11, rainwater is discharged along the liquid outlet holes 16.

[0031] The lifting platform 12 includes a fixed end 17 and a movable end 18, the top of the movable end 18 is fixedly connected to the bottom of the liquid accumulating tank 11, the bottom of the fixed end 17 is fixedly connected to the top of the main body 1, and the movable end 18 is slidably sleeved on the outside of the fixed end 17, the interiors of the fixed end 17 and the movable end 18 are both hollow, and a pair of first telescopic rods 19 are symmetrically arranged inside the fixed end 17 and the movable end 18, the top of the first telescopic rod 19 is fixedly connected to the bottom of the liquid accumulating tank 11, the bottom end of the first telescopic rod 19 is fixedly connected to the top of the main body 1, the first telescopic rod 19 is vertically arranged to the bottom of the liquid accumulating tank 11 and the top of the main body 1, and a first return spring 20 is arranged around the outside of the first telescopic rod 19. When the rainfall is heavy, the water intake into the liquid trough 11 is greater than the water discharge, which increases the gravity of the liquid trough 11. The movable end 18 at the top of the lifting platform 12 is pushed downward and begins to move downward. At this time, the first telescopic rod 19 inside the lifting platform 12 is shortened, and its first return spring 20 is compressed, generating an upward thrust on the liquid trough 11. When the rainfall is light, the liquid trough 11 is reset under the elastic force of the first return spring 20.

[0032] A plurality of vertical rods 21 are vertically arranged at the four edges of the bottom of the liquid accumulation tank 11, and the bottom ends of the vertical rods 21 extend through the top of the main body 1 to the inside of the main body 1. Connecting shafts 22 are provided on the four edges of the top of the main body 1, and an outer sleeve 23 is rotatably provided on the outside of the connecting shaft 22. A pair of first side panels 10 are symmetrically arranged on the outside of the outer sleeve 23 outside the connecting shaft 22 on the left and right sides, and a pair of second side panels 13 are symmetrically arranged on the outside of the outer sleeve 23 outside the connecting shaft 22 on the front and rear sides. A flexible waterproof curtain is connected between the edges of adjacent first side panels 10 and second side panels 13, and a movable groove 24 is provided at the connection between the outer sleeve 23 and the main body 1. The bottom height of the vertical rod 21 matches the height of the outer sleeve 23, and a second telescopic rod 25 is horizontally connected between the bottom end of the vertical rod 21 and the inner middle part of the outer sleeve 23. When the liquid accumulation tank 11 moves downward, it also drives the vertical rod 21 downward, causing the second telescopic rod 25 connected to the bottom of the vertical rod 21 to rotate downward, driving the outer ring 23 connected to the other end of the second telescopic rod 25 to start rotating around the connecting shaft 22 in the direction away from the main body 1, thereby causing the first side panel 10 and the second side panel 13 on the top of the main body 1 to open, and at the same time driving the flexible waterproof curtain between the first side panel 10 and the second side panel 13 to open, protecting the main body 1 and preventing rainwater from flowing into the charging port 5 along the outer wall of the main body 1, causing the charging circuit to short-circuit.

[0033] The heat dissipation mechanism includes heat dissipation holes 28, which are provided in the middle of the left and right sidewalls of the main body 1 and are located on the lower side of the first side panel 10. A dust screen 32 is fixedly installed inside the heat dissipation holes 28. A mounting ring 31 is provided inside the heat dissipation holes 28. A mounting bracket 33 is fixedly installed on the inner sidewall of the mounting ring 31 at one end facing the charging module 14. The mounting bracket 33 is arranged perpendicular to the mounting ring 31, and a motor 34 is fixedly installed in the center of the mounting bracket 33. The heat dissipation holes 28 can dissipate heat from the main body 1, and the dust screen 32 prevents external dust from entering the interior of the main body 1.

[0034] A trigger button 46 is provided at the bottom of the motor 34. A bracket 39 is provided at the bottom of the mounting ring 31. The bracket 39 is arranged perpendicularly to the inner side wall of the main body 1. A piston 41 rod 40 is fixedly connected to the inner end of the bracket 39. The piston 41 rod 40 is arranged perpendicularly to the top of the main body 1. A piston 41 cavity is provided at the inner bottom of the piston 41 rod 40. The piston 41 is slidably connected to the inner wall of the piston 41 cavity. The bottom of the piston 41 cavity is filled with a thermosensitive liquid. A push rod 42 is fixedly connected to the top of the piston 41. The push rod 42 is located directly below the trigger button 46. When the temperature inside the main body 1 is too high, the thermosensitive liquid inside the piston 41 rod 40 expands due to the heat, pushing the piston 41 upward, driving the push rod 42 upward, causing the push rod 42 to generate an upward thrust on the trigger button 46, causing the motor 34 to start.

[0035] The output end of the motor 34 faces the heat dissipation hole 28. An output shaft 35 is provided at the output end of the motor 34. Several blades 36 are fixedly mounted on the outer wall of the inner end of the output shaft 35. These blades 36 are located inside the dust screen 32. The outer end of the output shaft 35 extends through the dust screen 32 to the outside of the heat dissipation hole 28. Several cleaning rods 37 are perpendicularly mounted on the outer side wall of the output shaft 35. The length of these cleaning rods 37 is less than the radius of the heat dissipation hole 28. Several cleaning brushes 38 are fixedly mounted on the side of the cleaning rod 37 facing the dust screen 32. When the motor 34 is started, the output shaft 35 begins to rotate, which in turn drives the blades 36 to rotate, generating wind force directed toward the outside of the heat dissipation hole 28. This allows heat within the main body 1 to be discharged through the heat dissipation hole 28, thereby reducing the temperature within the main body 1. The rotation of the output shaft 35 also drives the cleaning rod 37 to rotate, causing the cleaning brushes 38 on the outer side of the cleaning rod 37 to rotate, thereby cleaning the dust screen 32 and preventing clogging of the dust screen 32 and affecting heat dissipation.

[0036] The sealing mechanism includes a pair of side slides 29 that are slidably mounted at the bottom of the heat dissipation holes 28. Side sliding grooves 30 are defined at the junctions between the left and right outer walls of the main body 1 and the edges of the side slides 29. The length and width of the side slides 29 are both greater than the diameter of the heat dissipation holes 28. On rainy days, the side slides 29 seal the heat dissipation holes 28, preventing splashing water from entering the interior of the main body 1 along the heat dissipation holes 28.

[0037] Third telescopic rods 27 are rotatably connected between the ends of the top edge of the side slide 29 and the bottom edge of the first side panel 10. These third telescopic rods 27 are located on either side of the heat dissipation hole 28 and are perpendicular to the top edge of the side slide 29 and the bottom edge of the first side panel 10. When the second side panel 13 is raised, the third telescopic rods 27 connected to its bottom edge move upward while simultaneously rotating outward around the top edge of the side slide 29. At this point, the third telescopic rods 27 drive the side slide 29 to slide upward along the side guide grooves 30, thereby sealing the heat dissipation hole 28.

[0038] The transmission rod 26 is fixedly connected to the inner side wall of the bottom end of the vertical rod 21, and the transmission rod 26 is arranged in an inverted "L" shape. The bottom end of the transmission rod 26 is vertically connected to the cross rod 44, and the side wall of the push rod 42 is vertically opened with a connecting groove 43. The other end of the cross rod 44 extends to the inside of the connecting groove 43. The end of the cross rod 44 away from the transmission rod 26 is slidably connected to the push rod 42, and a second return spring 45 is connected between the end of the cross rod 44 away from the transmission rod 26 and the bottom of the connecting groove 43. On rainy days, the heat dissipation holes 28 are sealed. At this time, the vertical rod 21 moves downward, driving the transmission rod 26 to move downward, so that the cross bar 44 connected to the bottom of the transmission rod 26 moves downward in the connecting groove 43 until the cross bar 44 moves to the bottom of the connecting groove 43. Since the downward thrust of the cross bar 44 is much greater than the upward thrust of the push rod 42, the push rod 42 is fixed, thereby ensuring that the motor 34 is in the off state when the heat dissipation holes 28 are sealed, avoiding energy waste and saving energy.

[0039] Working principle: When the charging pile is in use, the charging gun 6 is pulled out from the charging interface 5 and inserted into the charging port of the new energy vehicle. The charging parameters can be controlled through the control panel 9. When maintenance is required, the switch 4 can be turned to open the cabinet door 3 for easy maintenance. The heat dissipation mechanisms on both sides can automatically dissipate heat when the temperature inside the main body 1 is too high. The main body 1 can be protected and sealed on rainy days through the protective mechanism and the sealing mechanism to prevent water from entering the main body 1 and causing a short circuit; on rainy days, rainwater enters the interior of the liquid accumulating tank 11, and the filter plate 15 can be provided to make external debris roll down along the filter plate 15 to prevent external debris from entering the interior of the liquid accumulating tank 11. After the rainwater enters the liquid accumulating tank 11, it flows along the liquid outlet 1 6 discharge, when the rainfall is heavy, the water inflow inside the sump 11 is greater than the water discharge, which increases the gravity of the sump 11, and the movable end 18 at the top of the lifting platform 12 begins to move downward under the downward thrust. At this time, the first telescopic rod 19 inside the lifting platform 12 is shortened, and its first return spring 20 is compressed, generating an upward thrust on the sump 11. When the rainfall is light, the sump 11 is reset under the elastic force of the first return spring 20. When the sump 11 moves downward, it also drives the vertical rod 21 downward, so that the second telescopic rod 25 connected to the bottom of the vertical rod 21 rotates downward, driving the outer ring 23 connected to the other end of the second telescopic rod 25 to rotate around the connecting shaft 22 in the direction away from the main body 1, from This causes the first side panel 10 and the second side panel 13 on the top of the main body 1 to open, and at the same time drives the flexible waterproof curtain between the first side panel 10 and the second side panel 13 to open, thereby protecting the main body 1 and preventing rainwater from flowing into the charging port 5 along the outer wall of the main body 1, causing a short circuit in the charging circuit; when the second side panel 13 rises, it drives the third telescopic rod 27 connected to its bottom edge to move upward while rotating outward around the top edge of the side slide 29. At this time, the third telescopic rod 27 drives the side slide 29 to slide upward along the side slide groove 30, thereby sealing the heat dissipation hole 28 and preventing splashing water from entering the interior of the main body 1 along the heat dissipation hole 28; the main body 1 can be cooled through the heat dissipation hole 28, and the dustproof net 32 ​​can prevent external dust from entering the main body Inside the body 1, when the temperature inside the body 1 is too high, the thermally sensitive liquid inside the piston 41 and the rod 40 expands due to the heat, pushing the piston 41 upward, driving the push rod 42 upward, so that the push rod 42 generates an upward thrust on the trigger button 46, so that the motor 34 is started. After the motor 34 is started, the output shaft 35 starts to rotate, driving the blades 36 to start rotating, thereby generating wind force to the outside of the heat dissipation hole 28, so that the heat inside the body 1 is discharged along the heat dissipation hole 28, thereby reducing the temperature inside the body 1. When the output shaft 35 rotates, it also drives the cleaning rod 37 to start rotating, so that the cleaning brush 38 outside the cleaning rod 37 rotates accordingly, thereby cleaning the dustproof net 32 ​​to prevent the dustproof net 32 ​​from being blocked and affecting the heat dissipation effect;On rainy days, when the heat dissipation holes 28 are sealed, the vertical rod 21 moves downward, driving the transmission rod 26 downward with it. This causes the crossbar 44 connected to the bottom of the transmission rod 26 to move downward within the connecting groove 43 until the crossbar 44 reaches the bottom of the connecting groove 43. Since the downward thrust on the crossbar 44 is much greater than the upward thrust on the push rod 42, the push rod 42 is fixed, thus ensuring that the motor 34 is in the off state when the heat dissipation holes 28 are sealed, thus avoiding energy waste and saving energy.
