Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to an intelligent snow removal system and a snow removal method for a pressure-bearing building roof. Background Art

[0002] With the continuous development of plateau resources, in order to solve the problem of outsiders adapting to and being able to work and live in plateau areas for a long time, it is necessary to develop an indoor space that can create the air environment of plains or low-altitude areas. The interior of this space is a positive pressure environment, that is, the indoor atmospheric pressure is 30 to 50 kPa higher than the outdoor atmospheric pressure. Therefore, a snow removal system for the roof of a pressure-bearing building that matches it is also crucial.

[0003] Plateau areas are cold and cold all year round, with thin air and low oxygen content. People from plains who travel or work in plateau areas need to live in pressure-bearing buildings that can increase pressure and supplement oxygen. Currently, pressure-bearing buildings mostly use steel structures. Due to the climate and environment of the plateau, snow and ice easily accumulate on the roofs of buildings, which puts additional pressure on the buildings themselves, may cause deformation of the building structure, and make the sealing of the pressure-bearing houses fail. The sliding of a large amount of snow may also cause casualties.

[0004] In the prior art, some methods of snow removal on roofs use heating to melt snow, while others use mechanical snow removal. Both methods require the addition of a set of drive-actuator mechanisms on the roof, which consumes a lot of extra energy and is complex and difficult to maintain.

[0005] In summary, there is an urgent need for a snow removal system and a snow removal method that has a simple structure and can achieve efficient and environmentally friendly snow removal to solve the problems existing in the prior art. Summary of the invention

[0007] An intelligent snow removal system for a pressure-bearing building roof includes a waste heat snow melting component, wherein the waste heat snow melting component includes a heat exchanger, a circulation pump, and a snow melting pipeline;

[0008] The air compressor and the heat exchanger are arranged in sequence, and the heat exchanger is used to cool the first high-temperature medium in the air compressor and then transport it to the use end;

[0009] The circulation pump, pipeline B, snow melting pipeline and pipeline A form a medium circulation system in sequence. The snow melting pipeline is arranged on the roof of the pressure-bearing building. The low-temperature medium in pipeline A can exchange heat with the first high-temperature medium in the heat exchanger to achieve temperature increase and become the second high-temperature medium. The second high-temperature medium is pumped to pipeline B and the snow melting pipeline in sequence through the circulation pump. The second high-temperature medium in the snow melting pipeline is used to remove snow accumulated on the roof of the pressure-bearing building.

[0010] Preferably, it further includes a third high-temperature medium replenishing device, which includes a third high-temperature medium storage tank and a replenishing pump arranged in sequence. The replenishing pump transports the third high-temperature medium in the third high-temperature medium storage tank into pipeline A located between the heat exchanger and the circulation pump.
