Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle charging piles, and in particular 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. Charging piles 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, some parking spaces in outdoor parking lots are specially equipped with electric vehicle charging piles to meet the energy replenishment needs of electric vehicles. Electric vehicle charging piles generate a lot of heat when working. Generally, there are array-distributed heat dissipation holes on the side walls of the charging piles to discharge the internal hot air. However, the existing technology has the following defects: In windy and rainy weather, rain will float with the wind, and the rain droplets will present a certain angle. When the trajectory of the rain is aligned with the heat dissipation holes of the charging pile, the rain may enter the charging pile and cause damage to the equipment inside the charging pile.

[0004] The direction of the heat dissipation holes is fixed during molding, which results in a limited air flow path, making it impossible to take away the heat inside the device, causing local overheating, thus affecting the heat dissipation effect of the charging pile. Summary of the invention

The lower end of the ball rod extends into the charging pile shell and is connected to a reset center of gravity block, the lower end of the reset center of gravity block is connected to a transmission rope, the other end of the transmission rope is connected to a transmission frame, and the other end of the transmission frame is connected to the upper end of the driving frame, and multiple sets of guide wheels are connected to the inner shell wall of the charging pile shell, and the transmission rope is arranged to bypass the guide wheels.

[0009] Furthermore, a guide ring is connected to the inner shell wall of the charging pile shell directly below the reset center of gravity block, the transmission rope is passed through the guide ring, and the edge of the inner ring wall of the guide ring is arranged in an arc shape.

[0010] Furthermore, a "cross"-shaped slide groove is symmetrically arranged on the inner wall of the ball holding chamber, and sliding balls are symmetrically connected to the side walls of the ball club located in the ball holding chamber. The sliding balls are slidably connected in the corresponding slide grooves, and sealing rings are symmetrically connected to the slide grooves on the inner wall of the ball holding chamber, and the inner ring of the sealing ring is sealingly and slidably connected to the ball club.

[0011] Furthermore, the air supply mechanism includes a temperature sensor connected to the inner shell wall of the charging pile shell, the bottom of the charging pile shell is connected to an air supply pipe, the inner shell bottom of the charging pile shell is connected to a position corresponding to the air supply pipe, the air supply pipe is a tube body with a bottom seal, a rain cover is sleeved on the outer tube wall of the air supply pipe, and a plurality of air inlets are distributed in a ring shape on the tube wall of the air supply pipe inside the rain cover, a filter is connected to the air inlet, the temperature sensor is connected to the controller signal through a wire, and the controller is connected to the fan control through a wire.

[0012] Furthermore, the air supply mechanism also includes a photosensitive component, which is arranged on the top of the inner shell of the charging pile shell, and the photosensitive component is connected to the controller through a wire signal. The photosensitive component includes a support ring mounted on the club, and the support ring is connected to the top of the inner shell of the charging pile shell through a support column. The lower end of the support ring is vertically staggered with two groups of opposing photoelectric sensors, and the two groups of opposing photoelectric sensors are connected to the controller signal through wires.

[0013] Furthermore, two grooves are provided at the lower end of the support ring, wherein a group of through-beam type photoelectric sensors are connected in the two grooves, and the two groups of through-beam type photoelectric sensors are not in the same horizontal plane.

[0014] Furthermore, a support frame is connected to the inner tube wall of the air supply pipe, and a rotating shaft is rotatably connected to the bottom of the support frame. A reset ring and fan blades are sequentially sleeved on the shaft wall of the rotating shaft in the vertical direction, and multiple elastic ropes are connected in a circular shape with the rotating shaft as the center between the support frame and the reset ring.

[0016] Beneficial effects of the present invention: The inclination angle of the wind guide baffle is directly affected by the wind force. The gas in the charging pile shell adjusts the air outlet path according to the inclination angle of the wind guide baffle. Especially when the wind force fluctuates, the wind guide baffle swings back and forth in the heat dissipation hole, so that the air movement path in the charging pile shell is constantly adjusted, thereby improving the heat dissipation effect of the charging pile's electric vehicles. Moreover, if it is windy but not raining, the air can also take away the heat by passing through the outer wall of the charging pile shell quickly.

[0017] When there is a strong wind, the wind guide baffle is forced to rotate to a vertical state, and the extension strips at both ends press against the inner and outer shell walls of the charging pile shell, cooperating with the wind guide baffle to block the heat dissipation holes, so that rainwater from the outside cannot enter the charging pile shell through the heat dissipation holes along the strong wind, causing damage to the electronic components in the charging pile shell. At this time, the rainwater flows downward on the outside of the charging pile shell, taking away the heat inside the charging pile.

[0018] When the fan is working, when the air moves upward in the air supply duct, the fan blades drive the rotating shaft and the reset ring to rotate, so that the elastic rope is deformed and wrapped around the rotating shaft until the elastic rope is at the maximum deformation value, and the fan blades stop rotating; when the fan stops working, under the action of the reset force of the elastic rope, the fan blades are driven to reverse, and the air in the charging pile shell is transported to the air supply duct. While the air in the air supply duct moves from the inside to the outside of the filter, the driving tube moves and drives the brush plate to make vertical reciprocating motion on the inside of the filter through the transmission rod. When the air blows back the filter, the bristles of the brush plate clean the surface of the filter, so that the dust adhered to the outside of the filter is loosened, ensuring that the dust on the surface of the filter can be cleaned.

DETAILED DESCRIPTION

[0021] In order to make the above objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] Example 1, reference Figure 1-8 , which is the first embodiment of the present invention, provides a rainproof electric vehicle charging pile for outdoor parking lots, including a charging pile shell 1, the charging pile shell 1 is made of a metal material that is easy to dissipate heat, and also includes: an air supply mechanism, installed at the bottom of the charging pile shell 1; a heat dissipation hole 2, the heat dissipation hole 2 is a long strip and has a plurality of them, which are evenly distributed along a vertical array and are opened on one side of the shell wall of the charging pile shell 1; a controller 3, installed on the inner shell wall of the charging pile shell 1 on the side away from the heat dissipation hole 2, and the controller 3 is connected to the air supply mechanism through a wire; an air guide baffle 4, each heat dissipation hole 2 is rotatably connected with an air guide baffle 4, when the wind force is too small, the air guide baffle The plate 4 is in an inclined state, and two extension strips 5 are staggeredly connected at the top and bottom edges of the wind guide baffle 4. The wind guide baffle 4 and the two extension strips 5 are designed as an integral whole, and a guide groove plate 6 is connected to the center of one side of the wind guide baffle 4 close to the controller 3; the driving frame 7 is in a ladder shape, and is transmission-connected to multiple guide groove plates 6. The driving frame 7 is slidingly connected to the charging pile shell 1 through the limiting parts on both sides; the wind sensing mechanism is arranged on the shell top of the charging pile shell 1, and is transmission-connected to the driving frame 7. The limiting part includes a limit rod connected to the inner shell wall of the charging pile shell 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.

[0023] Specifically, in windless weather, the wind guide baffle 4 is in a tilted state in the heat dissipation hole 2, and the air supply mechanism sends air with a lower outside temperature into the charging pile shell 1, and then discharges it to the outside of the charging pile shell 1 through the heat dissipation hole 2 along the tilt direction of the wind guide 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 in the guide slot plate 6, thereby pushing the wind guide baffle 4 to rotate upward in the heat dissipation hole 2. At this time, the gas in the charging pile shell 1 adjusts the air outlet path according to the tilt angle of the wind guide baffle 4. Especially in the process of fluctuating wind force, the wind guide baffle 4 is in the heat dissipation hole 2. The reciprocating swing in the heat hole 2 causes the air movement path in the charging pile shell 1 to be constantly adjusted, thereby improving the heat dissipation effect of the electric vehicle of the charging pile; when the wind force is too strong, the controller 3 controls the air supply mechanism to stop working, and the wind guide baffle 4 is forced to rotate to a vertical state, and the extension strips 5 at both ends are pressed against the inner and outer shell walls of the charging pile shell 1, and cooperate with the wind guide baffle 4 to block the heat dissipation hole 2, so that the outside rainwater cannot enter the charging pile shell 1 through the heat dissipation hole 2 along the strong wind, causing damage to the electronic components in the charging pile shell 1. At this time, the rainwater flows downward on the outside of the charging pile shell 1, taking away the heat in the charging pile.

[0024] Reference Figure 1-8 The wind sensing mechanism includes a ball holding chamber 8 embedded in the top of the charging pile shell 1, a ball rod 9 sealed and rotatably connected in the ball holding chamber 8, the top of the ball rod 9 extends to the outside of the charging pile shell 1 and is connected to a "cross"-shaped force frame 10, and four wind-receiving plates 11 are staggered and connected to the force frame 10, and 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 shell 1 and is connected to a reset center of gravity block 12, and the lower end of the reset center of gravity block 12 is connected to a transmission rope 13, and the other end of the transmission rope 13 is connected to a transmission frame 14, and 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 shell 1, and the transmission rope 13 is arranged around the guide wheel 15.

[0025] Specifically, when the wind blows outdoors, the wind will blow the wind receiving plate 11 in the force direction. When the wind force is greater than the gravity of the reset center of gravity block 12, the wind receiving plate 11 is forced to drive the ball club 9 to deflect in the ball holding chamber 8 according to the wind direction, and the reset center of gravity block 12 deflects synchronously, and applies an upward pulling force to the transmission frame 14 through the transmission rope 13, and guides the transmission rope 13 through the guide wheel 15. After the transmission frame 14 is forced, it pulls the drive frame 7 to move upward in the guide groove plate 6, thereby pushing the wind guide baffle 4 to deflect in the heat dissipation hole 2; when the wind stops blowing or the wind force decreases, under the action of the gravity of the reset center of gravity block 12, the ball club 9 drives the wind receiving plate 11 to reset.

[0026] Reference Figure 1-8A guide ring 16 is connected to the inner shell wall of the charging pile housing 1 just below the reset center of gravity block 12, and the transmission rope 13 is arranged through the guide ring 16, and the edge of the inner ring wall of the guide ring 16 is arranged in an arc shape.

[0027] Specifically, the guide ring 16 is used for guiding, so that the club 9 drives the center of gravity reset block 12 to deflect in any direction of front, back, left, or right to pull the transmission rope 13, and the guide wheel 15 will not affect the movement direction of the transmission rope 13.

[0028] Reference Figure 1-8 A "cross"-shaped slide groove 17 is symmetrically opened on the inner wall of the ball holding chamber 8, and a sliding ball 18 is symmetrically connected to the side wall of the ball rod 9 located in the ball holding chamber 8. The sliding ball 18 is slidably connected in the corresponding slide groove 17, and a sealing ring is symmetrically connected to the slide groove 17 on the inner wall of the ball holding chamber 8, and the inner ring of the sealing ring is sealed and slidably connected to the ball rod 9.

[0029] Specifically, the sealing between the club 9 and the ball holding chamber 8 is improved by the sealing ring. Since the sliding ball 18 can only slide in the sliding groove 17, it is ensured that the club 9 cannot rotate in the ball holding chamber 8 and can only deflect forward, backward, left and right in the ball holding chamber 8.

[0030] During use, when there is no wind, the air supply mechanism sends air with a lower outside temperature 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 wind guide baffle 4; when the wind blows outdoors, the wind will blow the wind receiving plate 11 in the force direction. When the wind force is greater than the gravity of the reset center of gravity block 12, the wind receiving plate 11 is forced to drive the club 9 to deflect in the ball holding chamber 8 according to the wind direction, and the reset center of gravity block 12 deflects synchronously, and applies an upward pulling force to the transmission frame 14 through the transmission rope 13, and the transmission rope 13 is pulled by the guide wheel 15. After receiving the force, the transmission frame 14 pulls the driving frame 7 to move upward in the guide groove plate 6, thereby pushing the wind guide baffle 4 to rotate upward in the heat dissipation hole 2. At this time, the gas in the charging pile shell 1 adjusts the air outlet path according to the inclination angle of the wind guide baffle 4. Especially in the process of fluctuating wind force, the wind guide baffle 4 swings back and forth in the heat dissipation hole 2, so that the air movement path in the charging pile shell 1 is constantly adjusted, thereby improving the heat dissipation effect of the electric vehicle of the charging pile; and if it is windy but not rainy, the air passes through the outer shell wall of the charging pile shell 1 quickly, which can also take away the heat.

[0031] When the wind force is too strong, the controller 3 controls the air supply mechanism to stop working. The air deflector 4 rotates under the 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 hole 2 and continues to maintain an inclined state, and the controller 3 controls the air supply mechanism to continue working to supply air.

[0032] Embodiment 2, referring to Figure 1-14 , which 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.

[0033] Specifically, the temperature sensor 19 intermittently detects the working temperature inside the charging pile housing 1, and converts the detected temperature value into temperature data information and transmits it to the controller 3. The controller 3 obtains the real-time working temperature V inside the charging pile housing 1 and compares it with the 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; When V ≧ Y, the controller 3 controls the fan 21 to work; When V < X, the controller 3 controls the fan 21 to stop working; 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.

[0034] Referring to Figure 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.

[0035] Specifically, the ball rod 9 is located between the two groups of opposed photoelectric sensors 37 and blocks 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 Z value, 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; 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. When it continues until V < X, the controller 3 controls the fan 21 to stop working.

[0036] Refer to Figure 1-14 , two grooves are opened 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.

[0037] Specifically, the two grooves make the two groups of opposed photoelectric sensors 37 not on the same horizontal plane, and the light between the two groups of opposed photoelectric sensors 37 will not affect each other.

[0038] Refer to Figure 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.

[0039] Specifically, when the fan 21 is working and the outside air moves upward in the air supply pipe 20, the air exerts an upward pushing force on the fan blades 28. After being subjected to the force, the fan blades 28 drive the rotating shaft 26 and the reset ring 27 to rotate, and stretch the elastic rope 29, so that the elastic rope 29 is wrapped around the rotating shaft 26 until the elastic rope 29 is at the maximum deformation value, and the fan blades 28 stop rotating. After the fan 21 stops working, under the action of the reset force of the elastic rope 29, the reset ring 27 and the rotating shaft 26 drive the fan blades 28 to reverse, and the air in the charging pile housing 1 is transported into the air supply pipe 20. The air in the air supply pipe 20 moves from the inside to the outside of the filter 24, and the dust adhering to the outside of the filter 24 is cleaned.

[0040] Reference Figure 1-14 A driving tube 30 is sleeved on the rotating shaft 26 located below the fan blades 28, and an elliptical driving groove 31 is opened on the inner tube wall of the driving tube 30. A driving pin 32 is connected to the shaft wall of the rotating shaft 26 located in the driving tube 30, and the other end of the driving pin 32 extends into the driving groove 31. A brush plate 33 is movably arranged in the air inlet 23, and the bristles of the brush plate 33 are movably arranged on the inner side of the filter 24. A supporting shaft 34 is symmetrically connected in the air inlet 23, and the supporting shaft 34 movably penetrates the brush plate 33. A transmission rod 35 is commonly connected between the brush plate 33 and the driving tube 30.

[0041] Specifically, when the rotating shaft 26 rotates, it drives the driving pin 32 to rotate in the driving groove 31 on the inner tube wall of the driving tube 30. As the driving pin 32 rotates, the driving tube 30 makes a vertical reciprocating motion in the air supply tube 20. When the driving tube 30 moves, the brush plate 33 is driven to reciprocate on the inner side of the filter 24 through the transmission rod 35. When the air blows back the filter 24, the bristles of the brush plate 33 clean the surface of the filter 24, so that the dust adhered to the outside of the filter 24 is loosened, ensuring that the dust on the surface of the filter 24 can be cleaned.

[0042] During use, the temperature sensor 19 intermittently detects the working temperature in the charging pile housing 1. When the set temperature Y is reached, the controller 3 controls the fan 21 to work. The air outside the charging pile housing 1 is filtered by the filter 24, enters the air supply pipe 20 through the air inlet 23, and then enters the charging pile housing 1 to dissipate heat for the electrical components. When the air moves upward in the air supply pipe 20, the air exerts an upward thrust on the fan blades 28. After the fan blades 28 are subjected to the force, they drive the rotating shaft 26 and the reset ring 27 to rotate, stretching the elastic rope 29 so that the elastic rope 29 is wrapped around the rotating shaft 26. After the elastic rope 29 is at the maximum deformation value, the fan blades 28 stop rotating; until the temperature sensor 19 detects that the charging pile is detected. After the working temperature in the shell 1 is lower than the set temperature X, the controller 3 controls the fan 21 to stop working. Under the action of the reset force of the elastic rope 29, the reset ring 27 and the rotating shaft 26 drive the fan blades 28 to reverse, and the air in the charging pile shell 1 is transported to the air supply pipe 20. While the air in the air supply pipe 20 moves from the inside to the outside of the filter 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, the brush plate 33 is driven by the transmission rod 35 to make a vertical reciprocating motion on the inside of the filter 24. When the air blows back the filter 24, the bristles of the brush plate 33 clean the surface of the filter 24, so that the dust adhered to the outside of the filter 24 is loosened, ensuring that the dust on the surface of the filter 24 can be cleaned.

[0043] The remaining structures are the same as those of Example 1.

[0044] Based on Examples 1-2, the working principle of the present invention is as follows: When there is no wind, since the club 9 is in a vertical state, it blocks the light between the two groups of opposing 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 work. The air outside the charging pile housing 1 is filtered by the filter 24, enters the air supply pipe 20 through the air inlet 23, and then enters the charging pile housing 1 to dissipate heat for the electrical components. When the air moves upward in the air supply pipe 20, the air exerts an upward thrust on the fan blades 28. After the fan blades 28 are subjected to the force, they drive the rotating shaft 26 and the reset ring 27 to rotate, stretching the elastic rope 29 so that the elastic rope 29 is wrapped around the rotating shaft 26 until the elastic rope 29 is at the maximum deformation value, and the fan blades 28 stop rotating. At this time, the air in the charging pile housing 1 is discharged through the heat dissipation holes 2.

[0045] Conversely, when the working temperature is V < X or there is outdoor 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 to 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 blower 21 to continue working. In this wind force range, if the wind force fluctuates, the air guide baffle 4 swings back and forth in the heat dissipation hole 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.

[0046] If the wind force is too large, causing the cue 9 to no longer block the light between the two pairs of opposed photoelectric sensors 37, the controller 3 controls the blower 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 the outside rainwater from entering the charging pile housing 1 through the heat dissipation hole 2 along with the strong wind, causing damage to the electronic components in 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 in 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, transporting the air in 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 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 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.

[0047] 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, and the controller 3 controls the air supply mechanism to continue working for air supply.

[0048] If only strong winds blow without rain, the air quickly passes through the outer shell wall of the charging pile housing 1, which can also take away heat.

[0049] Among them, the priority of wind force judgment is higher than the priority of temperature detection. Even if the temperature V in the charging pile shell 1 does not drop below X, if the wind force is judged to be ≧Z, the controller 3 judges that the wind force is too large, and the controller 3 still controls the fan 21 to stop working and directly enters the next detection cycle.
