Technical Field
[0001] This utility model relates to the field of filter dust removal technology, specifically a dustproof structure for DC charging piles that facilitates dust removal. Background Technology
[0002] With the rapid development of new energy vehicles, DC charging piles, as core infrastructure, directly impact user experience due to their reliability and durability. During operation, the internal electronic components of a charging pile generate significant heat, requiring ventilation and cooling through vents. However, dust and particulate matter from the external environment can easily enter the charging pile with airflow, leading to the following problems over time:
[0003] Reduced heat dissipation efficiency: Dust adheres to the heat sink or circuit board, hindering heat exchange, increasing the risk of component overheating, and even causing malfunctions;
[0004] Electrical safety hazards: Conductive dust may cause short circuits or poor contact, affecting the safe operation of charging piles;
[0005] High maintenance costs: Traditional filters require manual disassembly and cleaning periodically, which is cumbersome and increases the burden of operation and maintenance.
[0006] In existing technologies, dust prevention in charging piles mostly adopts a fixed filter structure. Although it can intercept some dust, the filter is easy to clog and inconvenient to clean. Although the self-cleaning filter proposed by existing technologies removes dust through vibration, it has problems such as incomplete cleaning and complex mechanism. Utility Model Content
[0007] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a dustproof structure for DC charging piles that integrates self-cleaning, efficient dust removal and intelligent adjustment, making it easy to remove dust.
[0008] The technical solution adopted by this utility model to achieve the above objectives is: a dustproof structure for a DC charging pile that facilitates dust removal, including a charging pile, a dust filter assembly, and a filter screen dust removal assembly. The outer wall of the charging pile is fixedly connected to the dust filter assembly, which is generally installed at the heat dissipation vent. During the ventilation and heat dissipation process of the charging pile, it effectively intercepts external dust and other substances. The dust filter assembly is equipped with a filter screen dust removal assembly, which is used to periodically remove the dust intercepted on the dust filter assembly, thereby improving the convenience of dust cleaning.
[0009] The dust filtration assembly includes a mounting block and a dust filter plate. The mounting block is fixedly connected to the outer wall of the charging pile.

External air can enter the charging pile through the heat dissipation vent, thereby effectively cooling the internal electrical components of the charging pile. The dust filter plate is fixedly connected inside the heat dissipation vent. The dust filter plate is used to filter the air passing through the heat dissipation vent to prevent external dust from entering the charging pile. A sliding groove hole is opened in the heat dissipation vent on one side of the dust filter plate. A filter screen dust removal assembly is installed in the sliding groove hole.
[0010] The filter dust removal assembly includes a dust removal plate and a driving device. A movable groove is provided on the mounting block at the lower end of the sliding groove hole. The dust removal plate is slidably connected within the sliding groove hole and the movable groove. A dust removal chamber is provided within the dust removal plate, and a roller brush chamber is provided at the upper end of the dust removal chamber. A suction port is provided on one side of the roller brush chamber, and the suction port is positioned opposite to the dust removal plate. Several evenly spaced ventilation holes are provided between the roller brush chamber and the dust removal chamber. A toothed groove is provided on one side of the dust removal plate, and the toothed groove is connected to the driving device. The driving device is located in the mounting block between the heat dissipation port and the movable groove. In use, the driving device and the toothed groove work together to drive the dust removal plate to move up and down along the sliding groove hole, thereby moving the suction port on one side of the dust removal plate along the dust removal plate. At this time, the suction force generated by the suction port can adsorb and clean the dust on the surface of the dust removal plate.
[0011] In the above technical solution, a cleaning roller is rotatably connected inside the brush cavity. The brush on the cleaning roller contacts the dust filter plate through the dust suction port. Rotating shafts are fixedly connected to both ends of the cleaning roller. The transmission shaft passes through the dust removal plate and is rotatably connected to the sliding guide block. A first gear is fixedly connected to the rotating shaft on one side of the sliding guide block. Wheel grooves are opened in the mounting blocks on both sides of the heat dissipation port. A sliding guide groove is opened in the mounting block on one side of the wheel groove. The sliding guide block is slidably connected in the sliding guide groove. The first gear is slidably connected in the wheel groove. A rack is fixedly connected to one side of the wheel groove. The rack meshes with the first gear.
[0012] In the above technical solution, the driving device includes a drive motor, a second gear, and a third gear. The second gear and the third gear are rotatably connected and meshed with each other in the mounting block on one side of the gear tooth groove. The second gear is meshed with the gear tooth groove. One end of the shaft of the third gear is fixedly connected to the drive motor, and the drive motor is fixedly connected in the mounting block.
[0013] In the above technical solution, a dust-proof plate is fixedly connected to the lower end of the dust removal chamber, and a fixed frame is fixedly connected to both sides of the upper end of the dust-proof plate. An inclined side plate is fixedly connected to the upper end of the fixed frame, and the other end of the inclined side plate is fixedly connected to the inner wall of the dust removal chamber.

[0014] In the above technical solution, a cleaning port is provided on the dust removal plate on one side of the dust separation plate, and a sealing cover is fixedly connected to the cleaning port by bolts.
[0015] In the above technical solution, a plurality of tapered tubes are fixedly connected to the lower end of the dust removal plate, an exhaust pipe is fixedly connected to the lower end of the tapered tubes, a solenoid valve is fixedly connected to the exhaust pipe, and an exhaust fan is fixedly connected to the lower end of the exhaust pipe.
[0016] The beneficial effects of this utility model are:
[0017] 1. Automated dust removal, reducing maintenance costs: This utility model uses a drive device to move the dust removal plate along the filter plate, combined with the rotating brushing of the cleaning roller and the negative pressure adsorption of the exhaust system, to achieve automatic cleaning of the filter plate. It eliminates the need for frequent manual disassembly and cleaning, significantly reducing operation and maintenance costs and improving the long-term reliability of the charging pile.
[0018] 2. High-efficiency dust removal and prevention of secondary pollution: The brush of the sweeping roller continuously sweeps the surface of the dust filter plate during the movement, loosening the attached dust. At the same time, the negative pressure generated by the suction port quickly sucks the dust into the dust removal chamber and intercepts and collects it through the dust filter screen, effectively avoiding the secondary dust problem caused by traditional vibration or back-blowing dust removal, and ensuring thorough cleaning.
[0019] 3. Optimize heat dissipation performance and extend equipment life: The dust filter plate intercepts dust while maintaining smooth ventilation, preventing dust from clogging the heat dissipation vents, ensuring efficient heat dissipation of the electronic components inside the charging pile, preventing performance degradation or damage caused by overheating, thereby extending the service life of the equipment.
[0020] 4. Compact structure and strong adaptability: The dust removal components adopt a modular design, which can be flexibly adapted to the heat dissipation ports of different charging piles. The air volume of the exhaust system is adjustable, and the suction power can be adjusted according to the dust concentration in the environment. While ensuring the dust removal effect, energy consumption is reduced, making it suitable for a variety of complex working conditions.
[0021] 5. Convenient maintenance and efficient cleaning: The bottom of the dust removal chamber is equipped with a removable sealing cover, which makes it easy to clean the accumulated dust regularly. At the same time, the combination design of the tapered tube and the exhaust tube makes the dust collection more concentrated, further simplifying the maintenance process and improving the user experience.
