Description
Technical Field
The invention relates to the technical field of infrastructure facilities. More particularly, the invention relates to a temperature control clutch wind power driving device and a one-way cold guide pile.
Background
The perennial frozen soil area has perennial ground temperature lower than zero centigrade and forms perennial frozen soil layer in certain depth. China's frozen soil regions are mainly distributed in the northern regions of West, such as Qinghai-Tibet plateau, the great and small Khingan mountains in the northeast, Tianshan mountain and Altaishan mountain. National major engineering projects such as bridge engineering, power transmission engineering, road engineering and the like are constructed on the frozen soil layer. When the temperature of the stratum is lower than zero degree, the stratum is in a frozen state and has enough bearing capacity; however, when the temperature of the stratum is higher than zero, the soil layer is in a melting state, the bearing capacity of the stratum is low, and the bearing capacity of the building foundation is easy to lose. In addition, in the process of construction, the surface of the stratum is worried, so that frozen soil is easy to degrade; in addition, global warming is also accelerating the degradation of frozen soil underlying construction foundation works. Therefore, how to keep the permafrost foundation in a frozen state is a major technical problem faced by permafrost engineering.
The currently widely adopted frozen soil protection technology mainly comprises the following steps: (1) the broken stone layer is laid at the bottom or inside of the roadbed, and natural convection or forced convection of air inside the porous broken stone layer can help the soil layer at the lower part of the roadbed to dissipate heat, so that the effect of reducing the ground temperature is achieved. (2) Inserting a hot rod into the stratum, wherein the hot rod is divided into three sections from bottom to top, namely an evaporation section, a heat insulation section and a condensation section; the evaporation section of the hot rod is inserted into the stratum, the condensation section is exposed in the air, when the temperature of the external air is lower than that of the evaporation section, the liquid is evaporated in the liquid pool of the evaporation section at the bottom of the hot rod, condensed at the condensation section at the top of the hot rod and flows back to the liquid pool at the bottom under the action of gravity, and the effects of heat dissipation and cold storage are realized in a gas circulation mode; when the temperature of the external air is higher than that of the evaporation section, the same evaporation-condensation process cannot be formed, and the cooling effect of storing cold energy and abandoning heat is achieved. However, the heat exchange efficiency of the gas circulation is generally lower than that of the liquid, and if a novel unidirectional cold storage device can be developed, the unidirectional cold storage effect can be realized through the liquid circulation, and the device has important engineering practice significance for keeping the permafrost foundation in a frozen state.
In the permafrost regions of northeast and Qinghai-Tibet plateau of China, the wind speed is high in winter, the air temperature is low, if wind power is used as power, cold energy of the outside air temperature is captured and stored underground, and the permafrost is kept in a frozen state, so that the foundation bearing capacity of the building engineering in the permafrost regions is kept. However, if the wind power is not selectively utilized, the power carried by the wind power in the warm season may capture and store the heat energy of the outside air underground, so that the cold energy and the heat energy are mutually offset, and the cold storage capacity of the foundation cannot be increased. Therefore, the problem of heat intake in the warm season needs to be solved by using wind power as power to realize cold energy storage. If the power switching is realized through manual intervention (namely, the wind power transmission is manually cut off in warm seasons), the cost is increased, and the effect of automatic energy storage cannot be achieved. Therefore, a device is developed to automatically clutch the wind power transmission, namely, the wind power in cold seasons is automatically utilized, the warm air wind power is automatically abandoned, and then the wind power is used for driving the external air cold energy to be stored underground, so that the purpose of wind power driving one-way cold conduction is achieved, and the device has important engineering practice significance for keeping the frozen soil foundation in a frozen state for many years.

Outside wind-force drive wind cup 1 rotates to drive transfer line 2, then drive first magnet 3 and rotate, drive second magnet 7 and rotate, second magnet 7 drives blade 62 and rotates, is less than the melting point of phase transition liquid 5 when the outside temperature, and frozen phase transition liquid 5 forms a whole with blade 62, drives barrel 4 and rotates, and then transmits to fourth magnet 12 through third magnet 10, drives impeller 16 and rotates. Impeller 16 drive refrigerating fluid 15 is at the circulation of leading cold stake inner tube 14 and leading cold stake outer tube 13, and the heat dissipation of leading cold stake inner tube 14 top of refrigerating fluid 15 is inhaled coldly, takes cold energy to leading cold stake inner tube 14 bottom, and cold energy then gets into the soil layer from leading cold stake outer tube 13's bottom. Namely, the cold energy of the outside air is stored underground in a mode of fluid convection heat exchange.
When the external temperature is higher than the melting point of phase change liquid 5, because phase change liquid 5 is liquid, blade 62 rotates in barrel 4 but fails to drive whole barrel 4 and rotates, impeller 16 pause and rotates, refrigerating fluid 15 can't circulate, and convection heat transfer pauses, and the heat on the top end of the cold-conducting pile can't circulate to the bottom end of the cold-conducting pile through refrigerating fluid 15.

According to actual engineering requirements, the appropriate phase change liquid 5 is selected, namely, the appropriate transmission clutch is selected, the wind power driving device is selected according to specific temperature, cold energy is stored through convection heat exchange, and meanwhile, heat energy is abandoned after the convection heat exchange is suspended.

In another technical scheme, the material of the inner pipe 14 of the cooling-guiding pile is a heat-insulating material or a low-heat-conducting material, and the material of the outer pipe 13 of the cooling-guiding pile is a heat-conducting material. The top of the outer pipe 13 of the cold guiding pile is a steel pipe or an aluminum pipe coated with a high-reflection coating.

Therefore, the unidirectional cold guide pile is started for cold season convection heat exchange and cold storage, is suspended for warm season convection heat exchange, has small heat storage or even zero heat storage and large annual net cold storage capacity, and is favorable for keeping the soil body around the unidirectional cold guide pile in a frozen state. If specific actual engineering needs to store external cold energy at a certain position inside a stratum, the bottom end of the one-way cold guide pile can be inserted into the position, and meanwhile, the cold guide pile is transformed into a middle heat insulation structure with two heat conduction ends, so that the cold energy can be stored in place, and the loss of cold energy transmission along the way is reduced.
