[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

During operation, the fixing feet 11 are fixed to the roof inside the transportation area with bolts, and the external water pipe is connected to the input end of the water pump 17. Then, the fan 13 is installed through the fixing assembly. The filter screen 12 and protective net 14 are installed inside the housing 1. Then, the internal fan 13 is started to drive the airflow from one end of the filter screen 12 to the other end of the protective net 14. When the airflow enters the housing 1 through the filter screen 12, the filter screen 12 filters the airflow, thereby filtering out dust and impurities in the airflow. Then, the water pump 17 can be started periodically to send external water into the water pipe 15, and then the water is distributed into multiple nozzles 16 and sprayed downwards onto the filter screen 12. At this time, the filter screen 12 can be cleaned, thereby removing the dust adhering to the filter screen 12. The wastewater after cleaning enters the collection component. Through the above structure, with the nozzles 16, water pump 17 and water pipe 15, the filter screen 12 can be cleaned with water periodically to reduce the dust adhering to the filter screen 12 and causing the filter screen 12 to become clogged, thereby improving the stability of the equipment for ventilation in traffic areas.
[0020] like Figures 2 to 4As shown, the cleaning assembly includes a fixed cover 2; the fixed cover 2 is fixedly connected to the outer shell 1; a motor 21 is fixedly connected to the top of the fixed cover 2; a reciprocating lead screw 22 is fixedly connected to the output end of the motor 21; a slider 23 is mounted on the reciprocating lead screw 22; a brush plate 24 is fixedly connected to the side wall of the slider 23; a stabilizing component is provided inside the fixed cover 2; during operation, after the nozzle 16 finishes cleaning the filter screen 12, the motor 21 can be started to drive the reciprocating lead screw 22 to rotate. At this time, the reciprocating lead screw 22 will drive the slider 23 to slide up and down reciprocally inside the fixed cover 2, and the slider 23 will drive the brush plate 24 to move back and forth on the filter screen. The surface of the filter screen 12 is brushed back and forth, which can sweep away the dust that is tightly adhered to the filter screen 12. After the cleaning is completed, the motor 21 drives the brush plate 24 to move to the top of the fixed cover 2. At this time, the top of the fixed cover 2 must exceed the height of the outer shell 1. At this time, the brush plate 24 is located in the groove at the top of the fixed cover 2, so it will not block the components inside the outer shell 1. With the above structure, the fixed cover 2, the motor 21 and the reciprocating screw 22 are set up, and the slider 23 and the brush plate 24 are used together to reciprocate to brush the surface of the filter screen 12 after the filter screen 12 is rinsed with water, so that the filter screen 12 can be cleaned more thoroughly.
[0021] like Figure 5As shown, the fixing assembly includes a slide rail 3; the slide rail 3 is fixedly connected to the bottom of the outer shell 1; a bidirectional lead screw 31 is rotatably connected inside the slide rail 3; a turntable 32 is fixedly connected to the end of the bidirectional lead screw 31; an anti-slip component is provided on the outside of the turntable 32; a pair of support plates 33 are symmetrically threaded to the middle of the bidirectional lead screw 31; a pair of insert rods 34 are fixedly connected to the side wall of the support plate 33; fixing holes 36 are opened on the outer shell 1 and the fixing frame 18; the insert rods 34 are correspondingly arranged with the fixing holes 36; multiple positioning plates 35 are fixedly connected to the inner side wall of the outer shell 1; during operation, the fixing frame 18 and the fan 13 are pushed into the outer shell 1 from the end opening of the outer shell 1, and the fixing frame 18 contacts the fixing hole 36. Then, the turntable 32 is rotated to drive the bidirectional lead screw 31 to rotate. At this time, the pair of support plates 33 will slide in opposite directions inside the slide rail 3. When the turntable 32 rotates in the forward direction, it will drive the two... When the side support plates 33 are brought close together, the positioning plate 35 on the support plate 33 will be inserted into the fixing hole 36 on the outer shell 1 and the fixing frame 18, thereby fixing the fixing frame 18 and the fan 13 inside the outer shell 1. When the fan 13 needs to be repaired, the two side support plates 33 can be moved away from each other by reversing the turntable 32, so that the positioning plate 35 can be removed from the fixing hole 36, thereby releasing the fixing of the fixing frame 18 and the fan 13. Then the fixing frame 18 and the fan 13 can be taken out from the outer shell 1 for repair. Through the above structure, the slide rail 3, the two-way screw 31 and the turntable 32 are set up, and with the support plate 33, the insertion rod 34, the positioning plate 35 and the fixing hole 36, the installation and disassembly of the fan 13 can be facilitated, so as to reduce the situation where the fan 13 is fixed inside the outer shell 1, which would cause great inconvenience when repairing it in the narrow environment inside the outer shell 1.
[0022] like Figure 4 As shown, the collection component includes a discharge port 4; the discharge port 4 is located at the bottom of the outer casing 1; a guide hopper 41 is installed at the bottom of the discharge port 4; a discharge pipe 42 is connected to the bottom of the guide hopper 41; and multiple support rods 43 are fixedly connected inside the discharge port 4. During operation, after the filter screen 12 is installed inside the outer casing 1, the support rods 43 are located at the bottom of the filter screen 12 to support it. Then, the external pipe is connected to the discharge pipe 42, and the pipe outlet is connected to the sewage pipe. When the nozzle 16 cleans the filter screen 12, the sewage generated and the dust brushed off the surface of the filter screen 12 by the brush plate 24 will fall downwards and enter the guide hopper 41 from the discharge port 4. Then, it will enter the external pipe through the discharge pipe 42 and then enter the sewage pipe. Through the above structure, the discharge port 4, the guide hopper 41, and the discharge pipe 42 are set to facilitate the collection of sewage and dust generated when cleaning the filter screen 12, so as to reduce the pollution caused by sewage spillage.
[0023] like Figure 4As shown, the stabilizing component includes a vertical rod 5; the vertical rod 5 is fixedly connected inside the fixed cover 2; a support block 51 is slidably connected to the vertical rod 5; the support block 51 is fixedly connected to the side wall of the brush plate 24; during operation, when the brush plate 24 reciprocates, it will drive the support block 51 to slide on the vertical rod 5. At this time, the vertical rod 5 and the support block 51 support the brush plate 24. Through the above structure, the stability of the brush plate 24 during movement can be improved, so as to reduce the deformation caused by the reverse force when the brush plate 24 brushes the filter screen 12.
[0024] like Figure 5 As shown, the anti-slip component includes a silicone ring 6; the silicone ring 6 is fixed to the side wall of the turntable 32; during operation, when the turntable 32 is rotated, the operator's hand will come into contact with the silicone ring 6 on its surface. Through the above structure, the silicone ring 6 is connected to the turntable 32, which can increase the friction between the turntable 32 and the operator's hand when rotating the turntable 32. At the same time, the flexible material of the silicone ring 6 can improve the comfort when rotating the turntable 32.
[0025] like Figure 4 As shown, the feed hopper 41 has a funnel-shaped structure; through the above structure, the funnel-shaped structure of the feed hopper 41 can reduce the dead corners inside, and can make the sewage inside discharged more cleanly.
[0026] During operation, the fixing feet 11 are bolted to the roof inside the traffic area, and the external water pipe is connected to the input end of the water pump 17. Then, the fan 13 is installed inside the housing 1 using the fixing assembly, and filter screens 12 and protective nets 14 are installed at both ends of the housing 1. The internal fan 13 is then started to drive airflow from one end of the filter screen 12 to the other end of the protective net 14. When the airflow enters the housing 1 through the filter screen 12, the filter screen 12 filters the airflow, thereby removing dust and impurities from the airflow. The water pump 17 can then be started periodically to send external water into the water pipe 15, which is then diverted into multiple nozzles 16 and sprayed downwards onto the filter screen 12. At this time, the filter screen 12 can be cleaned, thereby removing the dust and impurities adhering to the filter. After the dust on the filter screen 12 is cleaned, the wastewater from the cleaning enters the collection assembly. After the nozzle 16 finishes cleaning the filter screen 12, the motor 21 can be started to drive the reciprocating screw 22 to rotate. At this time, the reciprocating screw 22 will drive the slider 23 to slide up and down inside the fixed cover 2. The slider 23 will drive the brush plate 24 to brush back and forth on the surface of the filter screen 12, thereby sweeping away the dust that is tightly adhered to the filter screen 12. After the cleaning is completed, the motor 21 drives the brush plate 24 to move to the top of the fixed cover 2. At this time, the top of the fixed cover 2 must exceed the height of the outer shell 1. At this time, the brush plate 24 is located in the groove at the top of the fixed cover 2, so it will not block the components inside the outer shell 1. The fixing frame 18 and the fan 1 are connected from the end opening of the outer shell 1. 3. Push the bracket 18 into the outer casing 1 and make it contact the fixing hole 36. Then rotate the turntable 32 to drive the double-acting screw 31 to rotate. At this time, the pair of support plates 33 will slide in opposite directions in the slide rail 3. When the turntable 32 rotates in the forward direction, it will drive the support plates 33 on both sides to move closer to each other. At this time, the positioning plate 35 on the support plate 33 will be inserted into the fixing hole 36 on the outer casing 1 and the bracket 18, thereby fixing the bracket 18 and the fan 13 in the outer casing 1. When the fan 13 needs to be maintained, the turntable 32 can be reversed to drive the support plates 33 on both sides to move away from each other, thereby causing the positioning plate 35 to come out of the fixing hole 36, thus releasing the fixing of the bracket 18 and the fan 13. Then the bracket 18 can be... The blower 13 is removed from the housing 1 for maintenance. After the filter screen 12 is installed in the housing 1, the support rod 43 is located at the bottom of the filter screen 12 to support it. Then, the external pipe is connected to the discharge pipe 42, and the pipe outlet is connected to the sewage pipe. When the nozzle 16 cleans the filter screen 12, the sewage generated and the dust brushed off the surface of the filter screen 12 by the brush plate 24 will fall down and enter the guide hopper 41 from the discharge port 4. Then, it enters the external pipe through the discharge pipe 42 and then enters the sewage pipe. When the brush plate 24 moves back and forth, it will drive the support block 51 to slide on the upright 5. At this time, the upright 5 and the support block 51 support the brush plate 24. When the turntable 32 is rotated, the operator's hand will come into contact with the silicone ring 6 on its surface.
