Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle charging piles, and particularly to a rainproof electric vehicle charging pile for outdoor parking lots. Background Art

[0002] With the popularization of new energy vehicles, a large number of charging piles need to be installed in cities for supporting use. The charging pile can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0003] In order to facilitate the timely charging of electric vehicles in outdoor parking lots, electric vehicle charging piles are specially installed on some parking spaces in outdoor parking lots to meet the energy replenishment needs of electric vehicles. A large amount of heat is generated when the electric vehicle charging pile is working. Generally, there are arrayed heat dissipation holes on the side wall of the charging pile for discharging the internal hot air. However, the prior art has the following defects:

[0004] In rainy and windy weather, the rain will float with the wind, and the water droplets of the rain present a certain angle. When the trajectory of the rain aligns with the heat dissipation holes of the charging pile, the rain may enter the charging pile and damage the equipment inside the charging pile.

[0005] The orientation of the heat dissipation holes is fixed during molding, resulting in a limited path for air flow and unable to take away the heat inside the equipment, causing local overheating and thus affecting the heat dissipation effect of the charging pile. Summary of the Invention

[0010] Further, a guiding ring is connected to the inner wall of the charging pile housing directly below the reset gravity block, the transmission rope passes through the guiding ring, and the edge of the inner ring wall of the guiding ring is set to be arc-shaped.

[0011] Further, a "cross"-shaped sliding groove is symmetrically arranged on the inner wall of the ball-holding chamber, sliding beads are symmetrically connected to the side wall of the ball rod located in the ball-holding chamber, the sliding beads are slidably connected in the corresponding sliding grooves, and sealing rings are symmetrically connected to the inner wall of the ball-holding chamber with respect to the sliding grooves, and the inner ring of the sealing ring is in sealed sliding connection with the ball rod.

[0012] Further, the blowing mechanism includes a temperature sensor connected to the inner wall of the charging pile housing, an air supply pipe is communicated with the bottom of the charging pile housing, a fan is connected to the inner bottom of the charging pile housing corresponding to the position of the air supply pipe, the air supply pipe is a pipe body sealed at the bottom, a rainproof cover is sleeved on the outer wall of the air supply pipe, and a plurality of air inlets are annularly distributed on the pipe wall of the air supply pipe located in the rainproof cover, a filter screen is connected in the air inlets, the temperature sensor is connected to the controller through a wire for signal connection, and the controller is connected to the fan through a wire for control connection.

The support ring is connected to the top of the inner shell of the charging pile housing through a support column. Two groups of opposed photoelectric sensors are vertically and staggeredly connected to the lower end of the support ring. The two groups of opposed photoelectric sensors are signal-connected to the controller through a wire.

[0014] Further, two grooves are provided at the lower end of the support ring. One group of opposed photoelectric sensors is connected in the two grooves, and the two groups of opposed photoelectric sensors are not on the same horizontal plane.

[0015] Further, a support frame is connected to the inner pipe wall of the air supply pipe. The bottom of the support frame is rotatably connected to a rotating shaft.

A plurality of elastic ropes are annularly distributed and connected between the support frame and the reset ring with the rotating shaft as the center.

[0017] The beneficial effects of the present invention:

[0018] The inclination angle of the air guiding baffle is directly affected by the wind force. The gas in the charging pile housing adjusts the air outlet path according to the inclination angle of the air guiding baffle. Especially during the process of sudden changes in wind force, the air guiding baffle swings back and forth in the heat dissipation holes, so that the air movement path in the charging pile housing is continuously adjusted, improving the heat dissipation effect of the electric vehicle in the charging pile; and if it is only windy and not rainy, the air quickly passes through the outer wall of the charging pile housing, and heat can also be carried away.

[0019] When there is a strong wind, the air guiding baffle rotates to the vertical state under the action of force, and the extension strips at both ends abut against the inner and outer shell walls of the charging pile housing, and cooperate with the air guiding baffle to block the heat dissipation holes, so that the external rainwater cannot enter the charging pile housing along the strong wind through the heat dissipation holes, causing damage to the electronic components in the charging pile housing. At this time, the rainwater flows downward on the outer side of the charging pile housing, taking away the heat in the charging pile.

[0020] When the fan is working, as the air moves upward in the air supply duct, the fan blades drive the rotating shaft and the reset ring to rotate, causing the elastic rope to deform and wind around the rotating shaft. When the elastic rope reaches its maximum deformation value, the fan blades stop rotating. After the fan stops working, under the action of the restoring force of the elastic rope, the fan blades are driven to rotate in the reverse direction, transporting the air inside the charging pile housing to the air supply duct. As the air in the air supply duct moves from the inner side to the outer side of the filter screen, when the driving pipe moves, the brush plate is driven by the transmission rod to make a reciprocating vertical movement on the inner side of the filter screen. When the air back blows the filter screen, the bristles of the brush plate clean the surface of the filter screen, loosening the dust adhered to the outer side of the filter screen and ensuring that the dust on the surface of the filter screen can be cleaned off.

[0037] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0038] Example 1, referring to Figures 1-8 , which is the first embodiment of the present invention, provides a rainproof electric vehicle charging pile for an outdoor parking lot, including a charging pile housing 1 made of a heat-dissipating metal material, and further including: an air supply mechanism installed at the bottom of the charging pile housing 1; heat dissipation holes 2 which are long and strip-shaped and are arranged in a vertical array at equal intervals on one side wall of the charging pile housing 1; a controller 3 installed on the inner wall of the charging pile housing 1 on the side away from the heat dissipation holes 2, and the controller 3 is connected to the air supply mechanism through a wire for control; an air guide baffle 4 which is rotatably connected in each heat dissipation hole 2, and when the wind force is too small, the air guide baffle 4 is in an inclined state, and two extension strips 5 are alternately connected to the top and bottom edges of the air guide baffle 4, and the air guide baffle 4 and the two extension strips 5 are integrally designed, and a guide groove plate 6 is connected to the center of the side of the air guide baffle 4 close to the controller 3; a driving frame 7 which is in the shape of a ladder and is in transmission connection with a plurality of guide groove plates 6, and the driving frame 7 is slidably connected to the charging pile housing 1 through two side limit members; a wind-sensing mechanism arranged on the top of the charging pile housing 1 and in transmission connection with the driving frame 7, and the limit members include a limit rod connected to the inner wall of the charging pile housing 1, and a limit block is slidably connected to the limit rod, and the limit block is connected to the side wall of the driving frame 7.

[0039] Specifically, in windless weather, the air guiding baffle 4 is in an inclined state within the heat dissipation holes 2. The air supply mechanism sends the relatively cold outside air into the charging pile housing 1, and then it discharges to the outside of the charging pile housing 1 through the heat dissipation holes according to the inclined direction of the air guiding baffle 4. When it is windy, the wind sensing mechanism applies an upward pulling force to the driving frame 7, and the driving frame 7 moves upward within the guiding groove plate 6, thereby pushing the air guiding baffle 4 to rotate upward within the heat dissipation holes 2. At this time, the gas within the charging pile housing 1 adjusts the air outlet path according to the inclination angle of the air guiding baffle 4. Especially during the process of sudden changes in wind force, the air guiding baffle 4 swings back and forth within the heat dissipation holes 2, causing the air movement path within the charging pile housing 1 to continuously adjust, improving the heat dissipation effect of the electric vehicle on the charging pile. When the wind force is too large, the controller 3 controls the air supply mechanism to stop working, and the air guiding baffle 4 rotates under force to a vertical state. The extension strips 5 at both ends abut against the inner and outer shell walls of the charging pile housing 1, and cooperate with the air guiding baffle 4 to block the heat dissipation holes 2, preventing the outside rainwater from entering the charging pile housing 1 along with the strong wind through the heat dissipation holes 2 and causing damage to the electronic components within the charging pile housing 1. At this time, the rainwater flows downward on the outside of the charging pile housing 1, taking away the heat within the charging pile.

[0040] Referring to Figures 1-8 , the wind sensing mechanism includes a ball holding chamber 8 embedded and connected to the top of the charging pile housing 1, a ball rod 9 sealed and rotatably connected within the ball holding chamber 8. The top of the ball rod 9 extends outside the charging pile housing 1 and is connected to a cross-shaped force receiving frame 10. Four wind receiving plates 11 are connected in a staggered manner on the force receiving frame 10. Any two adjacent wind receiving plates 11 are arranged at an angle of 90°. The lower end of the ball rod 9 extends into the charging pile housing 1 and is connected to a reset gravity block 12. The lower end of the reset gravity block 12 is connected to a transmission rope 13. The other end of the transmission rope 13 is connected to a transmission frame 14. The other end of the transmission frame 14 is connected to the upper end of the driving frame 7. A plurality of guide wheels 15 are connected to the inner shell wall of the charging pile housing 1, and the transmission rope 13 is arranged around the guide wheels 15.

[0041] Specifically, when it is windy outdoors, the wind will blow the wind receiving plate 11 in the direction of the force. When the wind force is greater than the gravity of the reset gravity block 12, the wind receiving plate 11 drives the ball rod 9 to deflect within the ball holding chamber 8 according to the direction of the wind. The reset gravity block 12 deflects synchronously, and applies an upward pulling force to the transmission frame 14 through the transmission rope 13. The transmission rope 13 is guided by the guide wheels 15. After the transmission frame 14 is stressed, it pulls the driving frame 7 to move upward within the guiding groove plate 6, thereby pushing the air guiding baffle 4 to deflect within the heat dissipation holes 2. When the wind stops blowing or the wind force decreases, under the action of the gravity of the reset gravity block 12, the ball rod 9 drives the wind receiving plate 11 to reset.

[0042] Referring to Figures 1-8, a guiding ring 16 is connected to the inner wall of the charging pile housing 1 directly below the reset center of gravity block 12. The transmission rope 13 passes through the guiding ring 16, and the edge of the inner ring wall of the guiding ring 16 is arranged in an arc shape.

[0043] Specifically, through the guidance of the guiding ring 16, the cue 9 drives the reset center of gravity block 12 to deflect in any direction of front, back, left, or right, pulling the transmission rope 13, and the guide wheel 15 will not affect the movement direction of the transmission rope 13.

[0044] Refer to Figures 1-8 , a "cross"-shaped sliding groove 17 is symmetrically opened on the inner wall of the ball-holding chamber 8. Slide beads 18 are symmetrically connected to the side wall of the cue 9 located in the ball-holding chamber 8. The slide beads 18 are slidably connected in the corresponding sliding grooves 17. Sealing rings are symmetrically connected to the inner wall of the ball-holding chamber 8 with respect to the sliding grooves 17. The inner ring of the sealing ring is in sealed sliding connection with the cue 9.

[0045] Specifically, the sealing performance between the cue 9 and the ball-holding chamber 8 is improved through the sealing ring. Since the slide beads 18 can only slide within the sliding grooves 17, it is ensured that the cue 9 cannot rotate within the ball-holding chamber 8 and can only deflect in the front, back, left, or right directions within the ball-holding chamber 8.

[0046] During use, when there is no wind, the air supply mechanism sends the air with a lower temperature from the outside into the charging pile housing 1, and then discharges it to the outside of the charging pile housing 1 through the heat dissipation holes 2 along the inclined direction of the air guiding baffle 4; when the wind blows outdoors, the wind will blow the wind-receiving plate 11 in the force-receiving direction. When the wind force is greater than the gravity of the reset center of gravity block 12, the wind-receiving plate 11 drives the cue 9 to deflect within the ball-holding chamber 8 according to the wind blowing direction, and the reset center of gravity block 12 deflects synchronously. An upward pulling force is applied to the transmission frame 14 through the transmission rope 13, and the transmission rope 13 is guided by the guide wheel 15. After the transmission frame 14 is stressed, it pulls the driving frame 7 to move upward within the guide groove plate 6, thereby pushing the air guiding baffle 4 to rotate upward within the heat dissipation holes 2. At this time, the air in the charging pile housing 1 adjusts the air outlet path according to the inclination angle of the air guiding baffle 4. Especially during the process of sudden changes in wind force, the air guiding baffle 4 swings back and forth within the heat dissipation holes 2, making the air movement path in the charging pile housing 1 continuously adjusted, improving the heat dissipation effect of the electric vehicle of the charging pile; and if it is only windy and not rainy, the air quickly passes through the outer wall of the charging pile housing 1, which can also take away heat.

[0047] When the wind force is too strong, the controller 3 controls the air supply mechanism to stop working. The air deflector 4 rotates under force to the vertical state, and the extension strips 5 at both ends abut against the inner and outer shell walls of the charging pile housing 1, cooperating with the air deflector 4 to block the heat dissipation holes 2, so that external rainwater cannot enter the charging pile housing 1 through the heat dissipation holes 2 along with the strong wind, causing damage to the electronic components inside the charging pile housing 1. At this time, the rainwater flows downward on the outside of the charging pile housing 1, taking away the heat inside the charging pile. When the blowing stops or the wind force decreases, under the gravity of the reset gravity block 12, the ball rod 9 drives the wind receiving plate 11 to reset, the air deflector 4 opens from the heat dissipation holes 2, and continues to maintain the inclined state. The controller 3 controls the air supply mechanism to continue working and supply air.

[0048] Embodiment 2, referring to Figures 1-14 , is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the air supply mechanism includes a temperature sensor 19 connected to the inner shell wall of the charging pile housing 1. A air supply pipe 20 is communicated with the bottom of the charging pile housing 1. A fan 21 is connected to the inner bottom of the charging pile housing 1 corresponding to the position of the air supply pipe 20. The air supply pipe 20 is a pipe body with a sealed bottom. A rain shield 22 is sleeved on the outer wall of the air supply pipe 20. A plurality of air inlets 23 are annularly distributed on the pipe wall of the air supply pipe 20 located inside the rain shield 22. A filter screen 24 is connected inside the air inlets 23. The temperature sensor 19 is signal-connected to the controller 3 through a wire, and the controller 3 is control-connected to the fan 21 through a wire.

[0049] Specifically, the working temperature inside the charging pile housing 1 is intermittently detected by the temperature sensor 19, and the detected temperature value is converted into temperature data information and transmitted to the controller 3. The controller 3 obtains the real-time working temperature V inside the charging pile housing 1 and compares it with thresholds X and Y. Among them, the threshold X is the optimal working temperature range of the electrical components inside the charging pile housing 1, and the threshold Y is the warning temperature of the electrical components inside the charging pile housing 1, and X < Y;

[0050] When V ≧ Y, the controller 3 controls the fan 21 to work;

[0051] When V < X, the controller 3 controls the fan 21 to stop working;

[0052] The rain shield 22 is used to prevent rainwater from entering the air inlets 23. When the fan 21 works, the air outside the charging pile housing 1 passes through the filter screen 24 and then enters the air supply pipe 20 through the air inlets 23, and then enters the charging pile housing 1 to dissipate heat from the electrical components.

[0053] Referring to Figures 1-14, the air supply mechanism further includes a light sensor component, which is installed on the inner top of the charging pile housing 1. The light sensor component is signal-connected to the controller 3 through a wire. The light sensor component includes a support ring 36 sleeved on the ball rod 9. The support ring 36 is connected to the inner top of the charging pile housing 1 through a support column. Two groups of opposed photoelectric sensors 37 are vertically and staggeredly connected to the lower end of the support ring 36. The two groups of opposed photoelectric sensors 37 are signal-connected to the controller 3 through a wire.

[0054] Specifically, the ball rod 9 is located between the two groups of opposed photoelectric sensors 37, blocking the light between the two groups of opposed photoelectric sensors 37. When the ball rod 9 deflects, the two light rays between the ball rod 9 and the two groups of opposed photoelectric sensors 37 are displaced. When the wind force is too large and the deflection angle of the ball rod 9 is too large, the light between one group of opposed photoelectric sensors 37 returns to normal and is no longer blocked by the ball rod 9. This opposed photoelectric sensor 37 transmits a signal to the controller 3. The wind force judgment standard value Z can be set. Within the value of Z, the ball rod 9 still blocks the light between the two groups of opposed photoelectric sensors 37. When the wind force ≥ Z, the controller 3 determines that the wind force is too large, and the controller 3 controls the fan 21 to stop working;

[0055] When the wind force < Z, and the real-time working temperature V in the charging pile housing 1 ≥ Y, the controller 3 determines that the wind force is too small, and the controller 3 controls the fan 21 to continue working until V < X, and then the controller 3 controls the fan 21 to stop working.

[0056] Refer to Figures 1-14 , two grooves are formed at the lower end of the support ring 36. One group of opposed photoelectric sensors 37 is connected in the two grooves, and the two groups of opposed photoelectric sensors 37 are not on the same horizontal plane.

[0057] Specifically, due to the grooves, the two groups of opposed photoelectric sensors 37 are not on the same horizontal plane, and the light between the two groups of opposed photoelectric sensors 37 will not affect each other.

[0058] Refer to Figures 1-14 , a support frame 25 is connected to the inner pipe wall of the air supply pipe 20. The bottom of the support frame 25 is rotatably connected to a rotating shaft 26. A reset ring 27 and a fan blade 28 are sequentially sleeved on the shaft wall of the rotating shaft 26 in the vertical direction. A plurality of elastic ropes 29 are annularly distributed and connected between the support frame 25 and the reset ring 27 with the rotating shaft 26 as the center.

[0059] Specifically, when the fan 21 operates and the outside air moves upward in the air supply duct 20, the air exerts an upward driving force on the fan blades 28. After the fan blades 28 are stressed, they drive the rotating shaft 26 and the reset ring 27 to rotate, stretching the elastic rope 29, causing the elastic rope 29 to wind around the rotating shaft 26. When the elastic rope 29 reaches its maximum deformation value, the fan blades 28 stop rotating. After the fan 21 stops operating, under the action of the restoring force of the elastic rope 29, the reset ring 27 and the rotating shaft 26 drive the fan blades 28 to rotate in the reverse direction, sending the air inside the charging pile housing 1 into the air supply duct 20. The air in the air supply duct 20 moves from the inside to the outside of the filter screen 24, cleaning the dust adhering to the outside of the filter screen 24.

[0060] Referring to Figures 1-14 , a drive tube 30 is sleeved on the rotating shaft 26 below the fan blades 28. An elliptical drive groove 31 is formed on the inner wall of the drive tube 30. A drive pin 32 is connected to the shaft wall of the rotating shaft 26 located inside the drive tube 30, and the other end of the drive pin 32 extends into the drive groove 31. A brush plate 33 is movably arranged in the air inlet 23. The bristles of the brush plate 33 are movably arranged on the inner side of the filter screen 24. Support shafts 34 are symmetrically connected inside the air inlet 23. The support shafts 34 movably penetrate through the brush plate 33. A transmission rod 35 is commonly connected between the brush plate 33 and the drive tube 30.

[0061] Specifically, when the rotating shaft 26 rotates, it drives the drive pin 32 to rotate in the drive groove 31 on the inner wall of the drive tube 30. As the drive pin 32 rotates, the drive tube 30 makes a reciprocating motion in the vertical direction in the air supply duct 20. When the drive tube 30 moves, it drives the brush plate 33 to reciprocate on the inner side of the filter screen 24 through the transmission rod 35. When the air blows back against the filter screen 24, the bristles of the brush plate 33 clean the surface of the filter screen 24, loosening the dust adhering to the outside of the filter screen 24 and ensuring that the dust on the surface of the filter screen 24 can be cleaned off.

[0062] During use, the working temperature inside the charging pile housing 1 is intermittently detected by the temperature sensor 19. When the set temperature Y is reached, the controller 3 controls the fan 21 to operate. The air outside the charging pile housing 1 passes through the filter screen 24 and enters the air supply duct 20 through the air inlet 23, and then enters the charging pile housing 1 to dissipate heat from the electrical components. When the air moves upward in the air supply duct 20, the air exerts an upward driving force on the fan blade 28. After the fan blade 28 is stressed, it drives the rotating shaft 26 and the reset ring 27 to rotate, stretching the elastic rope 29 so that the elastic rope 29 winds around the rotating shaft 26 until the elastic rope 29 reaches the maximum deformation value, and then the fan blade 28 stops rotating. Until the temperature sensor 19 detects that the working temperature inside the charging pile housing 1 is lower than the set temperature X, the controller 3 controls the fan 21 to stop working. Under the action of the restoring force of the elastic rope 29, the reset ring 27 and the rotating shaft 26 drive the fan blade 28 to reverse, sending the air inside the charging pile housing 1 into the air supply duct 20. While the air in the air supply duct 20 moves from the inside to the outside of the filter screen 24, the driving pin 32 rotates in the driving groove 31 on the inner wall of the driving pipe 30. When the driving pipe 30 moves, it drives the brush plate 33 to reciprocate vertically on the inner side of the filter screen 24 through the transmission rod 35. When the air back blows the filter screen 24, the bristles of the brush plate 33 clean the surface of the filter screen 24, loosening the dust adhering to the outside of the filter screen 24 to ensure that the dust on the surface of the filter screen 24 can be cleaned off.

[0063] The remaining structure is the same as that of Embodiment 1.

[0064] Combining Embodiments 1-2, the working principle of the present invention is as follows:

[0065] When there is no wind, since the cue 9 is in a vertical state, blocking the light between the two pairs of opposed photoelectric sensors 37, at this time the temperature sensor 19 detects the working temperature inside the charging pile housing 1. When the working temperature V≥Y, the controller 3 controls the fan 21 to operate. The air outside the charging pile housing 1 passes through the filter screen 24 and enters the air supply duct 20 through the air inlet 23, and then enters the charging pile housing 1 to dissipate heat from the electrical components. When the air moves upward in the air supply duct 20, the air exerts an upward driving force on the fan blade 28. After the fan blade 28 is stressed, it drives the rotating shaft 26 and the reset ring 27 to rotate, stretching the elastic rope 29 so that the elastic rope 29 winds around the rotating shaft 26 until the elastic rope 29 reaches the maximum deformation value, and then the fan blade 28 stops rotating. At this time, the air inside the charging pile housing 1 is discharged through the heat dissipation holes 2.

[0066] Conversely, when the working temperature V < X or there is outdoor wind blowing, the wind will blow the wind-receiving plate 11 in the force-receiving direction. When the wind force is greater than the gravity of the reset gravity block 12, the wind-receiving plate 11 drives the cue 9 to deflect in the ball-holding chamber 8 according to the wind direction. The reset gravity block 12 deflects synchronously and applies an upward pulling force on the transmission frame 14 through the transmission rope 13. The transmission rope 13 is guided by the guide pulley 15. After the transmission frame 14 is stressed, it pulls the driving frame 7 to move upward in the guide groove plate 6, thereby pushing the air guide baffle 4 to rotate upward in the heat dissipation hole 2. At this time, the gas in the charging pile housing 1 adjusts the air outlet path according to the inclination angle of the air guide baffle 4. If the wind force is small, the inclination angle of the cue 9 is not large. Affected by the diameter of the cue 9, the light between the two pairs of opposed photoelectric sensors 37 is still blocked. The controller 3 will control the fan 21 to continue working. Within this wind force range, if the wind force fluctuates, the air guide baffle 4 swings back and forth in the heat dissipation hole 2, causing the air movement path in the charging pile housing 1 to be continuously adjusted, improving the heat dissipation effect of the electric vehicle of the charging pile.

[0067] If the wind force is too large, resulting in the cue 9 no longer blocking the light between the two pairs of opposed photoelectric sensors 37, the controller 3 controls the fan 21 to stop working. The air guide baffle 4 is stressed and rotates to the vertical state. The extension strips 5 at both ends abut against the inner and outer shell walls of the charging pile housing 1, and cooperate with the air guide baffle 4 to block the heat dissipation hole 2, preventing external rainwater from entering the charging pile housing 1 along with the strong wind through the heat dissipation hole 2 and causing damage to the electronic components inside the charging pile housing 1. At this time, the rainwater flows downward on the outside of the charging pile housing 1, taking away the heat inside the charging pile. At the same time, under the action of the restoring force of the elastic rope 29, the reset ring 27 and the rotating shaft 26 drive the fan blade 28 to reverse, conveying the air inside the charging pile housing 1 into the air supply pipe 20. While the air in the air supply pipe 20 moves from the inner side to the outer side of the filter screen 24, the driving pin 32 rotates in the driving groove 31 on the inner pipe wall of the driving pipe 30. When the driving pipe 30 moves, it drives the brush plate 33 to make a reciprocating motion in the vertical direction on the inner side of the filter screen 24. When the air back blows the filter screen 24, the bristles of the brush plate 33 clean the surface of the filter screen 24, loosening the dust adhered to the outer side of the filter screen 24 and ensuring that the dust on the surface of the filter screen 24 can be cleaned off.

[0068] When the blowing stops or the wind force decreases, under the action of the gravity of the reset gravity block 12, the cue 9 drives the wind-receiving plate 11 to reset. The air guide baffle 4 opens from the heat dissipation hole 2 and continues to maintain an inclined state. The controller 3 controls the air supply mechanism to continue working and supply air.

[0069] If there is only strong wind but no rain, the air quickly passes through the outer shell wall of the charging pile housing 1, which can also take away the heat.

[0070] Among them, the priority of wind force judgment is higher than that of temperature detection. Even if the temperature V inside the charging pile housing 1 does not drop below X, but if it is judged that the wind force ≧ Z and the controller 3 determines that the wind force is too large, the controller 3 still controls the fan 21 to stop working and directly enters the next detection cycle.
