[0002] Snow removal equipment is a tool and device specifically designed for clearing snow. It's particularly important in areas with frequent winter snowfall, ensuring efficient and rapid snow removal. However, in northern China, snow accumulation on light rail station roofs can easily form ice or large icicles due to temperature fluctuations. These ice and icicles can cause varying degrees of damage to pedestrians and vehicles below. Snow removal equipment uses compressed air to clear snow during snowfall, preventing it from turning into ice due to temperature fluctuations.

[0003] Existing light rail station rooftop snow-clearing devices that use compressed air for snow removal still have the following problems. Existing devices generally compress air and eject it through a nozzle to clear snow. Patent application publication number CN104631376B discloses an air snow-clearing device with an outlet at one end of the nozzle and an inlet at the other. The nozzle adopts a tapered structure, and the inlet diameter of the nozzle is larger than the outlet diameter. A motor is mounted at the outlet end of the nozzle, and a jet fan is mounted on the motor's output shaft. The outlet end of the nozzle is connected to one end of a curved pipe, and the other end of the curved pipe is connected to the end of the nozzle. The inlet end of the nozzle is mounted on an inner support frame, and the nozzle is fixed to an outer support frame. This invention is used for clearing areas such as car windows, roofs, and streets.

[0004] However, the above-mentioned device compresses air and sprays it out from the nozzle to clear the snow.

[0030] The nozzle 224 and the jet fan 225 can be used to clear the snow on the roof of the light rail station. When in use, the air pipe 222 is connected to the external air compressor, and then the air compression is started to allow air to enter the jet fan 225 and be sprayed out from the nozzle 224 to blow away the snow. At the same time, the size of the blown air can be adjusted by controlling the jet fan 225, thereby improving the snow clearing efficiency and having good practicality.
