Description

Technical Field

[0001] The present application relates to the technical field of phase change clutches, and more specifically, to a telescopic automatic opening and closing phase change clutch and a one-way guide cold pile. Background Art

[0002] Frozen soil refers to various rocks and soils with a temperature of 0°C or below and containing ice. It is the result of heat and mass exchange in the lithosphere-soil-atmosphere system and is extremely sensitive to temperature.

[0003] According to the duration of the frozen state, frozen soil can be divided into short-term frozen soil, seasonal frozen soil and permafrost, also known as permafrost. Structurally, it can be divided into two layers: the upper layer: called the seasonal melting layer or active layer, is the soil layer that melts in summer and freezes in winter every year. This layer will change significantly with the change of seasons and is the more active part of permafrost. The lower layer: the permafrost layer or permafrost, is the soil layer that is frozen all year round and will not be affected by seasonal changes. This layer is the more stable part of permafrost and the basis for the existence of permafrost.

[0004] In the field of engineering, permafrost engineering is a discipline that studies the impact of frozen soil on engineering construction and infrastructure. Due to the special properties of frozen soil, special considerations are required for the design and construction of engineering projects such as roads, houses and oil and gas pipelines in frozen soil areas.

[0005] In the prior art, there is a temperature-controlled clutch wind-driven device with patent number CN202010300822.7, which includes: a cylinder; a phase change fluid contained in a cylinder cavity; a wind cup, a transmission rod fixed on a rotating shaft, a first magnet being provided on the transmission rod, and a transmission rod being rotatably connected to the cylinder; a rotating member, which is arranged in the cylinder cavity, a second magnet being provided on the rotating member, and the second magnet and the first magnet are magnetically attracted to each other. The device has the function of utilizing natural wind power and automatically clutching according to a specific temperature setting. A one-way cold-conducting pile of a temperature-controlled clutch wind-driven device is also disclosed, comprising: a temperature-controlled clutch wind-driven device; an outer tube of the cold-conducting pile; an inner tube of the cold-conducting pile; an output rod is sealed and rotatably arranged in the outer tube of the cold-conducting pile and extends into the inner tube of the cold-conducting pile, an impeller is arranged on the output rod, and the inner tube of the cold-conducting pile and the outer tube of the cold-conducting pile both contain refrigerant, and the cold-conducting pile has the function of using the temperature-controlled clutch transmission to store cold energy while discarding heat energy, that is, automatically using the cold season wind power while automatically discarding the warm wind power, and then using the wind power to drive the external air cold energy to be stored underground, so as to achieve the purpose of wind-driven one-way cold-conducting. However, the above-mentioned transmission system is often unable to adjust the transmission speed according to the wind force, resulting in a suddenly increased shear force at the connection between the rotating part and the solid phase-change liquid when the wind speed suddenly increases, resulting in loosening and cracking of the solid connection between the rotating part and the phase-change liquid, relative rotation between the rotating part and the rotating drum, and unstable transmission.
