A gravity spring snow removal device

Abstract

The invention relates to a gravity spring snow removal device, comprising a lever plate, an elastic mechanism, a magnetic assembly and a rotating shaft; the magnetic assembly includes a first magnetic assembly and a second magnetic assembly, the lever plate is connected to the rotating shaft, The lever plate is movably connected around the rotation axis, the inside of the lever plate is provided with an elastic mechanism, one end of the inside of the lever plane is provided with a first magnetic assembly, and the air-temperature gasifier is provided with a second magnetic assembly. When the first magnetic assembly of the flat panel is close to the second magnetic group, the magnetic attraction force is constantly increasing until the first magnetic assembly and the second magnetic assembly are attracted together. At this time, the magnetic attraction force is the largest. The magnetic assembly continues to move down, and at this time, the magnetic attraction force is converted into a repelling force, and the gravity of the generated snow is used as a power source to realize the automatic snow removal function.

Description

technical field [0001] The invention relates to the technical field of snow removal, in particular to a gravity spring snow removal device. Background technique [0002] The gasification production process of the LNG storage and distribution station is: the ultra-low temperature liquid natural gas at minus 160 degrees enters the air-temperature vaporizer, exchanges heat with the outside air, and the liquid natural gas absorbs heat and then gasifies to form natural gas at normal temperature, which is then transported through pipeline To the urban gas pipeline network for downstream users. [0003] During the gasification heat exchange process, the water vapor in the air will form frost and adhere to the fins of the vaporizer when it is cold. As the heat exchange process progresses, the frost will gradually increase, and most of the frost will fall to the air temperature. around the foundation of the gasifier, and gradually form snow. The snow accumulation is getting higher ...

AI Technical Summary

Problems solved by technology

The existing snow removal method is artificial snow removal, which has the following disadvantages: 1. The snow removal efficiency is low. Under the large amount of gasification and unfavorable weather conditions, too much snow cannot be removed in time, resulting in air temperature 2. The labor intensity of personnel is high; 3. Operators are exposed to low-temperature field environment, which has adverse effects on personnel health
