The working principle is as follows: when the invention is used, firstly, the LED screen is installed through the installation hole 13, and the line of the LED screen is arranged in the housing 1, when the LED screen needs to be overhauled, the motor 11 is turned on, so that the output shaft of the motor 11 drives the first bevel gear 21 to rotate, further the first bevel gear 21 drives the second bevel gear 22 to effectively rotate, further the second bevel gear 22 drives the screw rod 23 to effectively rotate, along with the rotation of the screw rod 23, the piston 24 rises along with the rotation of the screw rod 23, further the piston 24 does not press the slide bar 292, further the blocking plate 291 rises under the elastic force of the first spring 29, further the gas in the air bag 295 flows into the inside of the air groove 26 through the conduit 293 and the one-way valve 294, further the air bag 295 contracts, further the sealing between the movable door 12 and the housing 1 is loosened, because the piston 24 makes the blocking plate 291 block the communication position between the guide pipe 293 and the air groove 26 by pressing the slide rod 292, the air in the air bag 295 can not enter the air groove 26 through the guide pipe 293, the seal between the movable door 12 and the shell 1 can not be loosened, the diamond block 31 is lifted along with the rotation of the screw rod 23, the rack 32 is driven to lift, the slider 17 is driven to lift along with the lifting of the rack 32, the support rod 16 supports the movable door 12 along with the lifting of the slider 17, and the movable door 12 is opened, so that the device is effectively overhauled by technicians, meanwhile, the defect that the LED screen is dismantled for overhauling is effectively avoided, the defect that the assembling precision is not enough after the LED screen is dismantled is avoided on one hand, and the tedious overhauling work caused by the technicians dismantling the LED screen for overhauling is also reduced on the other hand, the efficiency of work is effectually improved, also can be accurate overhaul the device simultaneously.

In the process that the rack 32 rises along with the screw rod 23, the clamping between the gear teeth at the top of the rack 32 and the gear 36 is disconnected, the gear teeth at the middle section of the rack 32 drive the gear 36 to rotate, the third bevel gear 37 rotates along with the rotation of the gear 36, and then the fourth bevel gear 38 is driven to rotate, after the fourth bevel gear 38 rotates 90 degrees, the bottom disc 41 and the top disc 46 also rotate 90 degrees, and then the bottom disc 41 and the top disc 46 drive the filter screen 42 to rotate 90 degrees, and the filter screen 42 is perpendicular to the window 18 at the moment, so that a technician can effectively and easily replace the filter screen 42.

After the maintenance work is finished, the motor 11 is controlled to rotate reversely, so that the output shaft of the motor 11 drives the first bevel gear 21 to rotate reversely, so that the first bevel gear 21 drives the second bevel gear 22 to rotate reversely effectively, so that the second bevel gear 22 drives the screw rod 23 to rotate reversely, along with the reverse rotation of the screw rod 23, the piston 24 is lifted along with the reverse rotation of the screw rod 23, so that the piston 24 is lowered, along with the lowering of the piston 24, the gas in the gas groove 26 is compressed, because the existence of the one-way valve 294, the gas in the gas groove 26 cannot enter the gas bag 295 after being compressed, along with the movement of the piston 24 to the bottom of the gas groove 26, the piston 24 presses down the sliding rod 292, so that the blocking plate 291 is lowered, the communication position between the gas groove 26 and the guide pipe 293 is opened, and the compressed gas in the gas groove 26 enters the gas bag 295, at this moment, the rack 32 and the slider 17 descend under the guide of the screw motion of the diamond block 31 and the screw rod 23, the movable door 12 rotates by taking the top of the shell 1 as the center under the guide of the slider 17 and the support rod 16, when the piston 24 opens the blocking plate 291, the movable door 12 coincides with the side edge of the shell 1, so that the air bag 295 effectively seals the coinciding gap between the movable door 12 and the shell 1, dust and flocculent impurities are effectively prevented from entering the inside of the shell 1, and the cleanness of the inside of the shell 1 is effectively guaranteed.

In the process of reverse rotation of the screw 23, the screw 23 drives the rack 32 to descend through the diamond block 31, so that the gear teeth in the middle of the rack 32 drive the third bevel gear 37 and the fourth bevel gear 38 to rotate 90 degrees, so that the chassis 41 and the top disc 46 drive the filter screen 42 to rotate 90 degrees, so that the filter screen 42 and the clamp are clamped between the first clamp block 49 and the second clamp block 491, after the top disc 46 and the chassis 41 rotate 90 degrees, the fan blade 43 and the brush strip 44 are located on the window 18 on the side away from the inside of the housing 1, and after the rack 32 moves to the bottom, the gear teeth at the top of the rack 32 clamp the gear 36, so as to effectively prevent the gear 36 from rotating, after the fan blade 43 is blown by outdoor wind, the rotation of the fan blade 43 drives the brush strip 44 to rotate, the brush strip 44 further effectively cleans the filter screen 42, and can also effectively clean impurities such as dust and flocs on the filter screen 42, make the effectual assurance of filter screen 42 clean and tidy, and then make wind energy can effectually pass through filter screen 42, and then carry out effectual heat dissipation to casing 1's inside, and impurity such as dust batting can fall to depositing in ash groove 34, only need will deposit ash groove 34 pull out after pour out impurity such as dust batting can, ten minutes convenient and fast.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention.
