[0029] The reciprocating cleaning component 2 further includes a motor 201, a fan blade 203, a reciprocating disk 206, a transmission rod 207 and a filter screen 209;

[0030] At the middle of the top end of the ventilation pipe 1, a motor 201 is fixedly installed. The input end of the motor 201 is electrically connected to the output end of an external power supply. The output shaft of the motor 201 is fixedly connected to a transmission gear assembly 202. The transmission gear assembly 202 is composed of three bevel gears meshing in sequence. One side of the transmission gear assembly 202 is fixedly connected to a fan blade 203. The inner side of the transmission gear assembly 202 is fixedly connected to a gear shaft 204. Both sides of the outer side of the gear shaft 204 are meshingly connected to rotating gears 205. One side of the rotating gear 205 is rotatably connected to the outer side of the ventilation pipe 1, which can limit the moving position of the rotating gear 205. One side of the rotating gear 205 is fixedly connected to a reciprocating disc 206. The inner side edges of the reciprocating disc 206 are staggeredly rotatably connected to transmission rods 207. One ends of the two transmission rods 207 are rotatably connected together to form a cleaning rod 208. The inner side edge of the ventilation pipe 1 is embedded and fixedly installed with a filter screen 209. One side of the cleaning rod 208 is in contact with the outer side of the filter screen 209, which can clean the impurities attached to the surface of the filter screen 209.

[0031] The shock absorption and protection assembly 3 further includes a shock absorption column 306 and a rubber pad 307;

[0032] At the top and bottom of both sides of the ventilation pipe 1, fixing rods 301 are fixedly installed. Both sides of the inner side of the fixing rods 301 are embedded and fixedly installed with spring dampers 302. One end of the spring damper 302 is fixedly connected to a sliding frame 303. The inner side of the sliding frame 303 is rotatably connected to a connecting rod 304. One ends of the four connecting rods 304 are rotatably connected together to form a protection plate 305. At the middle of one side of the fixing rod 301, a shock absorption column 306 is fixedly installed. At the top and bottom of one side of the protection plate 305, rubber pads 307 are fixedly installed. The shock absorption column 306 is located at the position on one side of the rubber pad 307, which can buffer the impact force generated when the protection plate 305 moves.

[0033] Working principle of the utility model: When the staff needs to dissipate heat from the electromechanical equipment, the staff starts the motor 201, which can make the transmission gear assembly 202 fixedly connected to the output shaft of the motor 201 rotate. Through the transmission of the transmission gear assembly 202, the fan blade 203 fixedly connected to one side of the transmission gear assembly 202 can rotate. Through the rotation of the fan blade 203, the gas in the outside world can be guided. During the gas flow, through the filter screen 209 fixedly installed on the inner side of the ventilation pipe 1, the impurities in the gas can be filtered. At this time, through the transmission of the transmission gear assembly 202, the gear shaft 204 can rotate. During the rotation of the gear shaft 204, through the meshing connection between the gear shaft 204 and the rotating gear 205, the reciprocating disk 206 fixedly connected to one side of the rotating gear 205 can be rotated. Through the rotating connection between the reciprocating disk 206 and the transmission rod 207, and the fact that one ends of the two transmission rods 207 are jointly and rotatably connected to the cleaning rod 208, the position of the cleaning rod 208 can be reciprocally moved. Through the contact between one side of the cleaning rod 208 and the outer side of the filter screen 209, the impurities attached to the surface of the filter screen 209 can be cleaned up.

[0034] When the ventilation pipe 1 is in use, if an external object collides with the components on both sides of the ventilation pipe 1, the external object first contacts the protection plate 305, and then the position of the protection plate 305 will be moved. During the movement of the protection plate 305, through the rotational connection between one side of the protection plate 305 and the connecting rod 304, the position of the sliding frame 303 rotatably connected to one end of the connecting rod 304 can be moved. Through the elastic action of the spring damper 302 fixedly installed on one side of the sliding frame 303, the impact force received by the protection plate 305 can be initially shock-absorbed. After that, if the protection plate 305 continues to move, through the collision between the rubber pad 307 fixedly installed on one side of the protection plate 305 and the shock-absorbing column 306, under the action of the shock-absorbing column 306, the protection plate 305 can be shock-absorbed for the second time, thereby avoiding the phenomenon that the external object collides with the components on both sides of the ventilation pipe 1.

[0035] Finally, it should be noted that the above are only preferred examples of the utility model and are not used to limit the utility model.
