[0017] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0018] Example 1: A heating and ventilation structure for a prefabricated power cabin, see Figures 1 to 3, including a cabin 1, the two ends of the cabin 1 are respectively connected with an air intake pipe 2 and an exhaust pipe 3, a filter cartridge 23 is rotatably connected between the two sides of the inner cavity of the air intake pipe 2, a rectangular tube 21 is provided in the inner cavity of the air intake pipe 2, one end of the rectangular tube 21 is adapted to the outer curvature of the filter cartridge 23, a driving motor 22 is installed at one end of the air intake pipe 2, the driving end of the driving motor 22 rotates through the exhaust pipe 3 and is connected to the center of one end of the filter cartridge 23, and the rectangular tube 21 below the filter cartridge 23 is opened. A first dust outlet 25 is provided, and a second dust outlet 24 is provided on the rectangular tube 21 on one side of the first dust outlet 25 and the air inlet pipe 2. A blower 42 is installed in the inner cavity of the cabin 1, and the air outlet end of the blower 42 is connected to the air outlet pipe 4. The air outlet pipe 4 passes through the cabin 1, the exhaust pipe 3 and one end of the filter cartridge 23 is placed at the center of the inner cavity of the filter cartridge 23. A plurality of air outlet holes 43 are equidistantly provided below the air outlet pipe 4 in the inner cavity of the filter cartridge 23. The inner cavity of the air inlet pipe 2 is close to the inner cavity of the cabin 1. A draft fan 6 is installed on one side. When working, the draft fan 6 is started to introduce air from the outside of the cabin 1 into the cabin 1 for ventilation and heat dissipation. When the cabin 1 is ventilated and heat-dissipated, the air entering the cabin 1 is filtered by the filter cartridge 23, thereby preventing a large amount of dust from entering the equipment in the cabin 1 and causing damage. In the process of air filtering, the drive motor 22 is started to drive the filter cartridge 23 to rotate at a uniform speed, so that the rectangular tube 21 attached to the surface of the filter cartridge 23 cleans the dust on the surface of the filter cartridge 23 and discharges it from the rectangular tube 21 through the second dust exhaust port 24. At the same time, the blower 42 is started to spray high-pressure airflow through the air outlet 43, thereby backwashing the filter cartridge 23, thereby cleaning the dust adhering to the surface of the filter cartridge 23 and discharging it through the first dust exhaust port 25, so that the filter cartridge 23 can be automatically cleaned without the need for personnel to regularly check and manually replace the filter cartridge 23. It is more convenient and reduces personnel costs.

[0019] For details, see Figure 1 and Figure 2 A timer 5 and a controller 51 are installed in the inner cavity of the cabin 1. The output end of the timer 5 is connected to the input end of the controller 51 through a wire, and the output end wire of the controller 51 is electrically connected to the input end of the drive motor 22. The timer 5 can be used to set the cleaning cycle of the filter cartridge 23. When the use time of the filter cartridge 23 reaches the set cleaning cycle, the controller 51 starts the drive motor 22 to rotate at a constant speed for a certain period of time and then stops, so that the drive motor 22 does not need to work continuously, thereby saving electricity and extending the service life of the drive motor 22.

[0020] For further information, see Figure 3Baffles 41 are fixedly connected to both sides of the bottom of the air outlet pipe 4 in the inner cavity of the filter cartridge 23. The two baffles 41 are distributed in an eight-shaped shape, and the other ends of the two baffles 41 are fitted with the inner wall of the filter cartridge 23. Through the setting of the baffles 41, the air flow area discharged by the air outlet 43 can be controlled, thereby preventing the filter cartridge 23 from being backwashed and causing dust to enter the cabin 1.
