[0002] Ultraviolet disinfection lamps are also called ultraviolet germicidal lamps and ultraviolet fluorescent lamps. A lamp that uses the bactericidal effect of ultraviolet rays for sterilization and disinfection. Ultraviolet disinfection lamps radiate ultraviolet rays with a wavelength of 253.7nm. The ultraviolet rays in this band have the strongest bactericidal ability and can be used to disinfect water, air, clothing, etc. It can be used to disinfect the air in laboratories and operating rooms that require clean air. Bacteria in the air can be killed after about 30 minutes of irradiation. Ultraviolet disinfection lamps are mainly divided into: high pressure, medium pressure and low pressure. Disinfection applications are mainly low pressure. In order to ensure the disinfection effect of ultraviolet disinfection lamps, ultraviolet disinfection lamps need to be wiped regularly. Since the ultraviolet disinfection lamp is installed at a relatively high position, it is necessary to climb high to wipe the lamp tube, which is inconvenient to wipe the lamp tube and there are safety hazards.

With the movement of the movable block 2, the length of the fixed rope 3 downstream of the third pulley 23 becomes longer, and the mounting plate 4 moves downward. After the mounting plate 4 moves to a suitable position, the motor 10 is turned off to wipe the ultraviolet disinfection lamp 40. Since the conductive spring plunger 45 is separated from the conductive terminal 15 at this time, the mounting plate 4 and the ultraviolet disinfection lamp 40 are in a non-powered state, it is safer to wipe and contact accidents are not likely to occur. After wiping is completed, the motor 10 is started, and the motor 10 drives the movable block 2 to reset, and the mounting plate 4 is also reset.
