Description
Technical Field
[0001] This invention relates to the technical field of heat dissipation devices for new energy charging piles, and specifically to a heat dissipation device for new energy charging piles. Background Technology
[0002] Charging stations provide efficient and fast charging for new energy vehicles, but they generate a significant amount of heat during the charging process. Common cooling methods in my country include natural cooling, air cooling, water cooling, and air conditioning. Due to factors such as size, cost, and reliability, most companies currently use air cooling. This inevitably introduces dust, corrosive gases, and moisture. Therefore, most companies install filters at the air inlet and outlet. After a period of use, the accumulation of dust and impurities on these filters can affect the speed at which the fan draws air from the outside, reducing the charging station's heat dissipation efficiency. Therefore, most charging stations have operators regularly replacing and inspecting the filters. However, in areas with high winds and low rainfall, dust and impurities accumulate on the charging station filters too quickly. These areas are often sparsely populated, making frequent maintenance difficult. As a result, the charging station filters can become heavily contaminated with dust and impurities before scheduled maintenance, severely impacting heat dissipation efficiency and causing overheating. Excessive heat can reduce the lifespan of internal components and even damage the charging station.
[0003] In view of the above, in order to overcome the above technical problems, the present invention designs a heat dissipation device for new energy charging piles, which solves the above technical problems. Summary of the Invention
[0004] The technical problem this invention aims to solve is that in areas with strong winds and low rainfall, the filters of charging stations are prone to rapid accumulation of dust and impurities. However, these areas are typically sparsely populated, making frequent maintenance of charging stations difficult. Therefore, the filters often accumulate a large amount of dust and impurities before regular maintenance, severely impacting the heat dissipation efficiency of the charging station. Over time, the temperature of the charging station gradually increases, potentially shortening the lifespan of internal components or even damaging the charging station itself.
[0005] To address the aforementioned technical problems, the present invention provides the following technical solution:
[0006] This invention provides a heat dissipation device for new energy charging piles, comprising a charging pile housing, a filter screen, a fan, a control panel, a charging module, and a temperature sensor. The charging pile housing has filters installed at both ends, a fan installed between the filters, a control panel installed on the side of the charging pile housing, a charging module installed inside the charging pile housing, and a temperature sensor installed on the charging module. The device also includes a heat dissipation maintenance device. The heat dissipation maintenance device is installed near the air inlet and outlet of the charging pile housing for maintaining the filters. This device works in conjunction with the filters to maintain the filters using an electric push rod when the charging pile temperature is too high.
[0007] By installing filters at both ends of the charging pile housing, a fan between the filters, and a temperature sensor on the charging module, this system can monitor the internal temperature of the charging pile in real time. When the temperature rises, the system automatically activates the heat dissipation mechanism to maintain the charging pile's operating temperature within an appropriate range, preventing overheating. Furthermore, a control panel is located on the side of the charging pile housing, allowing users to easily monitor and adjust the charging pile settings. Combined with the temperature sensor and heat dissipation maintenance device, the system possesses intelligent control capabilities, automatically adjusting the fan speed and heat dissipation mechanism according to actual needs to achieve efficient heat dissipation. The heat dissipation maintenance device uses an electric push rod to maintain the filters, helping to keep them clean and prevent the accumulation of dust and debris. This further ensures the normal operation of the fan and heat dissipation system, helping to extend the service life of the charging pile equipment. Through optimized design of the heat dissipation device, the charging pile can dissipate heat more effectively, thereby reducing energy loss caused by overheating. This helps improve energy utilization efficiency, reduce energy waste, and conforms to the principles of energy conservation and environmental protection. The internal temperature sensor and automatic control mechanism ensure stable operation of the charging pile under various operating conditions, thereby improving the system's reliability and stability.
[0008] The heat dissipation maintenance device includes a mounting bracket, an electric push rod, an L-shaped bracket, a brush, a fan blade bracket, a fan blade, a buffer spring, a proximity switch, and a vibration motor. The mounting bracket is fixedly installed on the side wall of the charging pile housing. The electric push rod is mounted on the mounting bracket, and an L-shaped bracket is mounted on the output end of the electric push rod. A brush is mounted on the short side wall of the L-shaped bracket. A fan blade bracket is fixedly installed on the side of the charging pile housing, and a fan blade is rotatably mounted on the fan blade bracket. A buffer spring is engaged between the fan blade bracket and the filter screen. A proximity switch is installed directly below the fan blade bracket. The proximity switch has an isosceles trapezoidal cross-sectional shape. The isosceles trapezoidal shape of the proximity switch can provide a larger contact area, thereby improving the sensing and prediction capabilities of the proximity switch and enhancing the performance of the heat dissipation maintenance device. A vibration motor is fixedly installed on the inner side of the filter screen, and the vibration motor is located above the electric push rod. The vibration motor is electrically connected to the electric push rod.
[0009] The heat dissipation maintenance device combines a brush, fan blades, and a vibrating motor to maintain the filter. This design allows for a more thorough cleaning of dust and dirt from the filter, ensuring the charging station's heat dissipation remains consistently efficient. The device utilizes electric actuators and a vibrating motor for automated operation. This eliminates the need for manual intervention, saving manpower and time. The combination of the brush and vibrating motor, along with the fan blade support design, effectively removes dust and dirt from the filter. This helps maintain the filter's ventilation, ensuring the charging station's normal operation and efficient heat dissipation. The vibrating motor loosens particles on the filter through vibration, making them easier for the brush and airflow to remove. This mechanism ensures a more thorough cleaning of the filter. A flexible telescopic hose is installed between the electric push rod sleeve and the long side wall of the L-shaped bracket, ensuring the push rod remains in a sealed environment during extension and retraction. This prevents dust and impurities from continuously falling onto the extended part of the push rod during extension and retraction, and also prevents wind and sand from impacting and scraping the push rod in windy and sandy weather, which could hinder its normal extension and retraction and affect the normal operation of the cleaning device. The use of a proximity switch can automatically trigger the operation of the heat dissipation maintenance device when maintenance is required, avoiding the tedious manual judgment and operation, and improving the intelligence level of the device. The isosceles trapezoidal cross-section shape allows the proximity switch to be more stably fixed to the side of the charging pile housing during installation. This reduces loosening or shaking, ensuring the normal operation and reliability of the proximity switch. Due to the characteristics of the isosceles trapezoid, the proximity switch can be more accurately aligned with the required position. This helps ensure the proximity switch's cooperation and coordinated operation with other devices, improving the performance of the entire heat dissipation maintenance device. The isosceles trapezoidal cross-section shape provides a more defined contact area, thereby improving the proximity switch's sensing predictability.
[0010] The short side of the L-shaped bracket is inclined near the side wall of the filter screen, and the short side of the L-shaped bracket is perpendicular to the axis of the filter screen hole, so that the short side of the L-shaped bracket can be inserted into the filter screen hole for cleaning, thereby cooperating with the heat dissipation maintenance device to maintain the heat dissipation device.
[0011] By setting the short side of the L-shaped bracket to be inclined and perpendicular to the filter screen hole axis, the short side of the L-shaped bracket can more precisely reach into the filter screen holes for cleaning. This ensures that dust and dirt are effectively scraped away, resulting in more thorough maintenance of the heat dissipation device. The inclined L-shaped bracket allows cleaning of a larger portion of the filter screen holes, including hard-to-reach corners. This allows the maintenance device to more comprehensively address dirt on the filter screen, ensuring continuous and efficient heat dissipation. The L-shaped bracket design works in conjunction with other components of the heat dissipation maintenance device to achieve maintenance. Through brushes, vibrating motors, and other components, the L-shaped bracket can better assist in cleaning, thereby improving the efficiency of the entire maintenance device. Because the L-shaped bracket can clean the filter screen more thoroughly, the frequency of manual intervention is reduced. This helps reduce maintenance costs and time, and improves the stability and reliability of the charging pile. More precise cleaning prevents the filter screen from becoming severely clogged, reducing the risk of overheating of the charging pile. This helps reduce the possibility of malfunctions and extend the lifespan of the charging pile.
[0012] The brush is made of two parts: the part closer to the electric push rod is a soft brush, which is used to clean impurities from the surface of the filter screen; the other part further away from the electric push rod is a hard brush, which is used to clean the more tightly attached dust and impurities from the filter screen.
[0013] The design incorporates both soft and hard brushes to achieve a more refined cleaning effect based on different types of impurities. The soft brush easily removes surface impurities, while the hard brush effectively cleans more tightly adhered dust. By dividing the brush into two parts, it can accommodate different types and states of impurities. Whether it's minor surface impurities or tightly adhered dust, the appropriate brush can thoroughly clean them. The synergistic effect of the soft and hard brushes achieves a more comprehensive maintenance effect. This ensures that the maintenance device can fully remove various contaminants from the filter screen, thereby maintaining good heat dissipation efficiency. Using the appropriate brush to clean the filter screen reduces filter screen wear. The soft brush reduces surface scratches, while the hard brush removes adhered hard particles, extending the filter screen's lifespan.
[0014] The buffer spring, in conjunction with the vibration motor, periodically shakes the impurities on the filter screen, thereby maintaining the heat dissipation device without affecting the operation of the filter screen.
[0015] The combination of a buffer spring and a vibration motor allows impurities on the filter screen to be periodically shaken without affecting its normal operation. This non-intrusive maintenance ensures that the charging station continues to provide heat dissipation during maintenance. The periodic shaking continuously loosens impurities on the filter screen, making them easier to clean, helping to maintain the filter's ventilation and improving the charging station's heat dissipation efficiency. The automated operation of the buffer spring and vibration motor, combined with other components of the heat dissipation maintenance device, makes the maintenance process almost entirely manual. Improved heat dissipation efficiency extends equipment life and increases reliability. Heat dissipation maintenance does not affect the normal operation of the filter screen or cause excessive vibration, thus ensuring the normal and stable operation of the charging station and reducing the risk of malfunction.
[0016] The electric push rod includes a sleeve, a push rod, a telescopic hose, a connecting rod, a baffle plate, a slide groove, a wear-resistant plate, and a guide groove. The sleeve is fixedly installed on the mounting bracket, and the push rod is slidably installed coaxially inside the sleeve. The cross-sectional shape of the sleeve is "U". The "U" shape of the sleeve can provide a larger support area, thereby enhancing the stability of the sleeve.
[0017] The U-shaped cross-sectional shape provides a larger support area, thereby enhancing the stability of the sleeve. This reduces unnecessary swaying during the sliding of the electric push rod, ensuring more stable movement of the maintenance device. Since the U-shaped sleeve can guide the sliding of the electric push rod more smoothly and reduce friction, it helps to reduce energy loss and improve the efficiency of the maintenance device.
[0018] A telescopic hose is installed at one end of the sleeve near the brush. The other end of the telescopic hose is connected to the side wall of the long side of the L-shaped bracket. One end of the connecting rod is slidably installed on the side of the push rod. A baffle plate is fixedly installed at the other end of the connecting rod, and the baffle plate is located below the vibration motor. A sliding groove is formed between the sleeve and the baffle plate. A wear-resistant plate is installed on the side of the baffle plate near the filter screen. A guide groove is formed in the charging pile housing on the right side of the baffle plate. The width of the guide groove is equal to the sum of the widths of the baffle plate and the wear-resistant plate.
[0019] Through the design of the telescopic hose and push rod, the electric push rod can slide within the sleeve and achieve precise connection with the filter screen via components such as connecting rods and baffles. This design makes the movement of the maintenance device more flexible and precise. A telescopic hose is installed between the electric push rod sleeve and the long side wall of the L-shaped bracket, ensuring the push rod remains in a sealed environment during extension and retraction. This prevents dust and impurities from continuously falling onto the extended part of the push rod during extension and retraction, and protects against impacts and scraping from sandstorms in windy weather, which could prevent the push rod from extending or retracting properly and affect the normal operation of the cleaning device. The combination of the connecting rod and baffle ensures precise positioning of the filter screen during movement, thereby more effectively maintaining and removing dust and dirt from the filter screen. The presence of wear-resistant plates and guide grooves ensures the durability and stability of the maintenance device. Wear-resistant plates reduce wear on the baffles, while guide grooves ensure stable movement of the maintenance device. Through the synergistic action of the sliding grooves and baffles, the maintenance device can periodically shake the filter screen, effectively dislodging dust and dirt from it. This helps the maintenance equipment to perform cleaning tasks more effectively.
[0020] The filter screen has filter holes. The angle between the vertical line of the filter screen and the axis of the filter hole is acute, and the angle of the filter hole is downward. The inclined design of the filter hole is to reduce the frictional resistance of dust and impurities falling, so that the dust and impurities fall to the outside of the charging pile. The end of the filter hole near the fan is located above the other end.
[0021] By tilting the filter screen's aperture axis, frictional resistance is reduced as dust and impurities fall from the screen, facilitating more efficient removal and improving maintenance. The tilted aperture design also makes it easier for dust and impurities to fall towards the outside of the charging station. This natural tendency helps keep the filter clean and reduces the risk of clogging. Because one end of the filter screen near the fan is positioned above the other, dust and impurities are guided towards the fan and then discharged from there to the outside of the charging station. This design ensures that dust does not accumulate on the filter, maintaining stable heat dissipation. As dust and dirt fall from the filter and accumulate on the outside of the charging station, filter maintenance becomes easier. Operators can more easily clean the area around the charging station, ensuring proper equipment operation. The tilted filter screen design helps reduce dust accumulation on the filter, decreasing maintenance frequency, thereby reducing maintenance costs and time, and improving the availability of the charging station.
[0022] The beneficial effects of this invention are as follows:
[0023] 1. This invention designs a heat dissipation maintenance device that monitors the patency of the filters at the air inlet and outlet using fan blades and proximity switches. Combined with a temperature sensor, it identifies whether the filter blockage is causing reduced heat dissipation efficiency. The device then cleans the filter to resolve the issue, preventing heat buildup inside the charging pile, which could affect the lifespan of internal components or even damage the charging pile.
[0024] 2. This invention designs a filter screen. When the electric push rod is started, the vibration motor installed on the filter screen starts synchronously, causing the filter screen to vibrate. The vibration of the filter screen can reduce the adhesion between dust and impurities and the filter screen. Therefore, the brush can more easily clean the dust and impurities off the filter screen. Moreover, the dust and impurities inside the filter screen holes are more likely to fall out from the inclined filter screen holes under the combined action of vibration and gravity.
[0025] 3. This invention designs an electric push rod with a movable groove inside the mounting bracket. A baffle plate is slidably installed inside the movable groove. When the push rod moves, it drives the baffle plate to move back and forth synchronously through the connecting rod. The baffle plate blocks the filter screen holes, preventing some dust and impurities from entering the charging pile through the filter screen holes when the brush cleans the filter screen, thus affecting the heat dissipation device of the charging pile.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0040] like Figure 1 and 2 As shown, the present invention provides a heat dissipation device for a new energy charging pile, including a charging pile housing 1, a filter screen 2, a fan 3, a control panel 4, a charging module 5, and a temperature sensor 6. The charging pile housing 1 has filter screens 2 installed at both ends, and a fan 3 installed between the filter screens 2. The control panel 4 is installed on the side of the charging pile housing 1, and the charging module 5 is installed inside the charging pile housing 1. The temperature sensor 6 is installed on the charging module 5. The device also includes a heat dissipation maintenance device 7. The heat dissipation maintenance device 7 for maintaining the filter screen 2 is installed near the air inlet and air outlet of the charging pile housing 1. The heat dissipation maintenance device 7 works with the filter screen 2 to maintain the filter screen 2 using an electric push rod 72 when the charging pile temperature is too high.
[0041] By installing filters 2 at both ends of the charging pile housing 1, a fan 3 between the filters 2, and a temperature sensor 6 on the charging module 5, the system can monitor the internal temperature of the charging pile in real time. When the temperature rises, the system automatically activates the heat dissipation mechanism to maintain the operating temperature of the charging pile within an appropriate range and prevent overheating. In addition, a control panel 4 is also provided on the side of the charging pile housing 1, allowing users to easily monitor and adjust the charging pile settings. Combined with the temperature sensor 6 and the heat dissipation maintenance device 7, the system has intelligent control functions, automatically adjusting the fan 3 speed and heat dissipation mechanism according to actual needs to achieve efficient heat dissipation. The heat dissipation maintenance device 7 maintains the filters 2 using an electric push rod 72, helping to keep the filters 2 clean and prevent the accumulation of dust and debris. This further ensures the normal operation of the fan 3 and the heat dissipation system, helping to extend the service life of the charging pile equipment. Through the optimized design of the heat dissipation device, the charging pile can dissipate heat more effectively, thereby reducing energy loss caused by overheating. This helps improve energy utilization efficiency, reduce energy waste, and conforms to the principles of energy conservation and environmental protection. The internal temperature sensor 6 and automatic control mechanism ensure that the charging pile maintains stable operation under various working conditions, thereby improving the reliability and stability of the system.
[0042] like Figure 4 and 8 As shown, the heat dissipation maintenance device 7 includes a mounting bracket 71, an electric push rod 72, an L-shaped bracket 73, a brush 74, a fan blade bracket 75, a fan blade 76, a buffer spring 77, a proximity switch 78, and a vibration motor 79. The mounting bracket 71 is fixedly installed on the side wall of the charging pile housing 1. The electric push rod 72 is mounted on the mounting bracket 71. The output end of the electric push rod 72 is mounted on the L-shaped bracket 73. The brush 74 is mounted on the short side wall of the L-shaped bracket 73. The fan blade bracket 75 is fixedly installed on the side of the charging pile housing 1. The fan blade bracket 75 rotates... A fan blade 76 is mounted on the filter screen 2. A buffer spring 77 is snapped between the fan blade support 75 and the filter screen 2. A proximity switch 78 is mounted directly below the fan blade support 75. The cross-sectional shape of the proximity switch 78 is an isosceles trapezoid. The isosceles trapezoidal proximity switch 78 can provide a larger contact area, thereby improving the sensing and prediction capabilities of the proximity switch 78 and enhancing the performance of the heat dissipation maintenance device 7. A vibration motor 79 is fixedly mounted on the inner side of the filter screen 2, and the vibration motor 79 is located above the electric push rod 72. The vibration motor 79 is electrically connected to the electric push rod 72.
[0043] When the heat dissipation maintenance device 7 is activated, it works in conjunction with a brush 74, fan blades 76, and a vibration motor 79 to maintain the filter 2. This design allows for a more thorough cleaning of dust and dirt from the filter 2, ensuring continuous and efficient heat dissipation of the charging station. The heat dissipation maintenance device 7 utilizes electric actuators 72 and a vibration motor 79 for automated operation. This eliminates the need for manual intervention, saving manpower and time. The combination of the brush 74 and the vibration motor 79, along with the fan blade bracket 75, effectively removes dust and dirt from the filter 2. This helps maintain the ventilation effect of the filter 2, ensuring the normal operation and heat dissipation efficiency of the charging station. The vibration motor 79 loosens particles on the filter 2 through vibration, making them easier for the brush 74 and airflow to remove. This mechanism ensures a more thorough cleaning of the filter 2. A flexible hose 723 is installed between the sleeve 721 of the electric push rod 72 and the long side wall of the L-shaped bracket 73, so that the push rod is in a sealed environment during the extension and retraction process. This prevents dust and impurities from falling on the extended part of the push rod during the extension and retraction process, and also prevents the push rod from being unable to extend and retract normally due to the impact and scraping of wind and sand in windy and sandy weather, which would affect the normal use of the cleaning device. The use of the proximity switch 78 can automatically trigger the operation of the heat dissipation maintenance device 7 when maintenance is required, avoiding the tediousness of manual judgment and operation, and improving the intelligence level of the device.
[0044] like Figure 3 and 11 As shown, the short side of the L-shaped bracket 73 is inclined near the side wall of the filter screen 2, and the short side of the L-shaped bracket 73 is perpendicular to the axis of the filter screen hole 21, so that the short side of the L-shaped bracket 73 extends into the filter screen hole 21 for cleaning, thereby cooperating with the heat dissipation maintenance device 7 to maintain the heat dissipation device.
[0045] The short side of the L-shaped bracket 73 is angled and perpendicular to the axis of the filter mesh 21, allowing it to more precisely reach into the mesh for cleaning. This ensures that dust and dirt are effectively scraped away, resulting in more thorough maintenance of the heat dissipation device. The angled L-shaped bracket 73 allows for cleaning of a larger portion of the filter mesh 21, including hard-to-reach corners. This allows the maintenance device to more comprehensively address contamination on the filter 2, ensuring continued efficient heat dissipation. The L-shaped bracket 73 works in conjunction with other components of the heat dissipation maintenance device 7 to maintain the heat dissipation device. Through the brush 74, vibration motor 79, and other components, the L-shaped bracket 73 better assists in cleaning, improving the overall efficiency of the maintenance device. Because the L-shaped bracket 73 cleans the filter 2 more thoroughly, the frequency of manual intervention is reduced. This helps reduce maintenance costs and time, improving the stability and reliability of the charging station. More precise cleaning prevents the filter 2 from becoming severely clogged, reducing the risk of overheating. This helps reduce the likelihood of malfunctions and extends the lifespan of the charging station.
[0046] like Figure 7 As shown, the brush 74 is made of two parts. The part closer to the electric push rod 72 is a soft brush 74, which is used to clean impurities from the surface of the filter screen 2. The other part further away from the electric push rod 72 is a hard brush 74, which is used to clean the densely attached dust and impurities on the filter screen 2.
[0047] After brush 74 brushes the surface of filter screen 2, the design incorporates both soft and hard brushes 74 to achieve a more refined cleaning effect based on different types of impurities. The soft brush 74 easily removes surface impurities, while the hard brush 74 effectively cleans more tightly adhered dust. By dividing the brush 74 into two parts, it can accommodate different types and states of impurities. Whether it's minor surface impurities or tightly adhered dust, it can be thoroughly cleaned by the appropriate brush 74. The synergistic effect of the soft and hard brushes 74 achieves a more comprehensive maintenance effect. This ensures that the maintenance device can fully remove various contaminants from filter screen 2, thereby maintaining good heat dissipation efficiency. Using the appropriate brush 74 to clean filter screen 2 can reduce wear on filter screen 2. The soft brush 74 can reduce surface scratches, while the hard brush 74 can remove adhered hard particles, extending the service life of filter screen 2.
[0048] like Figure 3 As shown, the buffer spring 77, in conjunction with the vibration motor 79, periodically shakes the impurities on the filter screen 2, thereby maintaining the heat dissipation device in conjunction with the heat dissipation maintenance device 7 without affecting the operation of the filter screen 2.
[0049] The combination of the buffer spring 77 and the vibration motor 79 allows impurities on the filter screen 2 to be periodically shaken without affecting its normal operation. This non-intrusive maintenance ensures that the charging pile continues to provide heat dissipation during maintenance. The periodic shaking continuously loosens impurities on the filter screen 2, making it easier to clean and maintaining its ventilation, thus improving the charging pile's heat dissipation efficiency. The automated operation of the buffer spring 77 and vibration motor 79, combined with other components of the heat dissipation maintenance device 7, makes the maintenance process almost entirely manual. Improved heat dissipation efficiency extends equipment life and increases reliability. Heat dissipation maintenance does not affect the normal operation of the filter screen 2 or cause excessive vibration, thereby ensuring the normal and stable operation of the charging pile and reducing the risk of malfunctions.
[0050] like Figure 4 , 5 As shown in Figures 6 and 10, the electric push rod 72 includes a sleeve 721, a push rod 722, a telescopic hose 723, a connecting rod 724, a baffle plate 725, a sliding groove 726, a wear-resistant plate 727, and a guide groove 728. The sleeve 721 is fixedly installed on the mounting bracket 71. The cross-sectional shape of the sleeve 721 is "U". The "U" shape of the sleeve 721 can provide a larger support area, thereby enhancing the stability of the sleeve.
[0051] When a telescopic hose 723 is installed between the sleeve 721 of the electric push rod 72 and the long side wall of the L-shaped bracket 73, the U-shaped cross-sectional shape can provide a larger support area, thereby enhancing the stability of the sleeve 721. This reduces unnecessary shaking during the sliding of the electric push rod 72, ensuring more stable movement of the maintenance device. Since the U-shaped sleeve 721 can guide the sliding of the electric push rod 72 more smoothly and reduce friction, this helps to reduce energy loss and improve the efficiency of the maintenance device.
[0052] like Figure 4 , 5 As shown in Figures 6 and 10, the push rod is slidably mounted coaxially within the sleeve 721. A telescopic hose 723 is installed at one end of the sleeve 721 near the brush 74. The other end of the telescopic hose 723 is connected to the side wall of the long side of the L-shaped bracket 73. One end of the connecting rod 724 is slidably mounted on the side of the push rod 722. A baffle plate 725 is fixedly installed at the other end of the connecting rod 724, and the baffle plate 725 is located below the vibration motor 79. A sliding groove 726 is provided between the sleeve 721 and the baffle plate 725. A wear-resistant plate 727 is installed on the side of the baffle plate 725 near the filter screen 2. A guide groove 728 is provided in the charging pile housing 1 on the right side of the baffle plate 725. The width of the guide groove 728 is equal to the sum of the widths of the baffle plate 725 and the wear-resistant plate 727.
[0053] Through the design of the telescopic hose 723 and the push rod 722, the electric push rod 72 can slide within the sleeve 721 and achieve precise connection with the filter screen 2 through components such as the connecting rod 724 and the baffle plate 725. This design makes the movement of the maintenance device more flexible and precise. The telescopic hose 723 is installed between the sleeve 721 of the electric push rod 72 and the long side wall of the L-shaped bracket 73, ensuring the push rod is in a sealed environment during extension and retraction. This prevents dust and impurities from continuously falling onto the extended part of the push rod during extension and retraction, and also prevents wind and sand from impacting and scraping the push rod in windy and sandy weather, which could cause the push rod to malfunction and affect the normal use of the cleaning device. The combination of the connecting rod 724 and the baffle plate 725 ensures precise positioning of the filter screen 2 during movement, thereby more effectively maintaining and removing dust and dirt from the filter screen 2. The presence of the wear-resistant plate 727 and the guide groove 728 ensures the durability and stability of the maintenance device. The wear-resistant plate 727 reduces wear on the baffle plate 725, while the guide groove 728 ensures stable movement of the maintenance device. Through the synergistic action of the slide groove 726 and the baffle plate 725, the maintenance device can periodically shake the filter screen 2, effectively shaking off dust and dirt. This helps the maintenance device to better complete its cleaning tasks.
[0054] like Figure 7 , 8 As shown in Figure 9, the filter screen 2 has filter screen holes 21. The angle between the vertical line of the filter screen 2 and the axis of the filter screen hole 21 is an acute angle, and the angle of the filter screen hole 21 is downward inclined. The inclined design of the filter screen hole 21 is used to reduce the frictional resistance of dust and impurities falling, so that the dust and impurities fall to the outside of the charging pile. The end of the filter screen hole 21 near the fan 3 is located above the other end.
[0055] By tilting the axis of the filter screen 21, the frictional resistance encountered when dust and impurities fall from the filter screen 2 is reduced, facilitating more effective removal and improving maintenance. The tilted design of the filter screen 21 makes it easier for dust and impurities to fall towards the outside of the charging station. This natural tendency helps keep the filter screen 2 clean and reduces the risk of clogging. Since one end of the filter screen 21 closest to the fan 3 is positioned above the other, dust and impurities can be guided towards the fan 3 and then discharged from there to the outside of the charging station. This design ensures that dust does not accumulate on the filter screen 2, maintaining stable heat dissipation. As dust and dirt fall from the filter screen 2 and accumulate outside the charging station, maintenance of the filter screen 2 becomes more convenient. Operators can more easily clean the environment around the charging station, ensuring proper equipment operation. The tilted design of the filter screen 21 helps reduce dust accumulation on the filter screen 2, reducing maintenance frequency, thereby reducing maintenance costs and time, and improving the availability of the charging station.
[0056] During operation, when the charging pile is in standby mode, the electric push rod 72 is initially extended. At this time, the baffles 725 of the air outlet and air inlet will completely seal the filter screen 21. Therefore, the external environment cannot affect the internal components of the charging pile in standby mode.
[0057] When a car owner uses a charging station to charge a new energy vehicle, the control system first controls the electric push rod 72 to retract, preventing the push rod from blocking the filter screen 2 and affecting the air intake and exhaust speed of the filter screen 2. Simultaneously, the vibration motor 79, in conjunction with the brush 74, cleans the dust and impurities accumulated on the charging station filter screen 2 during standby. After cleaning, the fan 3 starts synchronously with the charging module 5, drawing in outside air through the air inlet and expelling the air inside the charging station through the air outlet, thus cooling the interior of the charging station. The airflow inside the charging station drives the fan blades 76 to rotate. When the temperature value sent to the control system by the temperature sensor 6 exceeds the set value, the proximity switch 78 is activated. The proximity switch 78 is electrically connected to the control system. Each time a fan blade passes over the proximity switch 78, it is triggered, and the control system counts. Every 60 seconds, the control system compares the set value with the count value to determine if the filter screen 2 is blocked.
[0058] When the count value is greater than or equal to the set value, the control system determines that the filter 2 is ventilated smoothly. At this time, the inability of the charging module 5 to dissipate heat is not caused by the filter 2 being blocked, and the control system controls the charging module 5 to stop running. When the count value is less than the set value, the control system shuts down the charging module 5 and the fan 3, and then starts the electric push rod 72 to perform a reciprocating motion. The electric push rod 72 drives the brush 74 to reciprocate and wipe the surface of the filter 2. At the same time as the electric push rod 72 is running, the vibration motor 79 starts synchronously to act on the filter 2, assisting the brush 74 in cleaning the filter 2. Meanwhile, the baffle plate 725 also blocks the filter hole 21 on the other side under the action of the connecting rod 724, preventing the dust and impurities cleaned by the brush 74 from entering the charging pile through the filter hole 21 due to ejection. After the electric push rod 72 reciprocates 3 times, the control system restarts the fan 3 and the charging module 5. When the fan 3 reaches the rated speed and stabilizes, the control system resets the count to zero and starts counting again. If the count value is greater than or equal to the set value after 60 seconds, the charging pile is charging normally, and the control system resets the count to zero and starts counting again for 60 seconds. If the count value is less than the set value, the control system controls the charging module 5 and the fan 3 to disconnect the power supply.
