FROZEN SOIL STABILIZATION DEVICE Russian patent published in 2023 - IPC E02D3/115 

FIELD: construction.

SUBSTANCE: invention relates to devices for cooling and freezing soil used in the construction of engineering structures erected in permafrost areas for cold accumulation at the base of structures. The technical result consists in integration of the use of a mobile alternative source of electricity with simultaneous temperature control of thermoelectric modules depending on the climatic temperature in real time and optimization of the refrigerant temperature with the provision of seasonal use of permanently installed thermosiphons. The technical result is achieved by the fact that the device for stabilizing frozen soils contains underground and ground parts of a tubular sealed housing filled with refrigerant, which are, respectively, an evaporator and a condenser, while the above-ground part of the tubular sealed housing is made detachable and consists of a permanently installed condenser that is constantly in communication with evaporator, and a removable power supply unit and change the temperature of the refrigerant, made in the form of a DC wind turbine with a vertical axis of rotation, the mast of which is mounted on a U-shaped cylindrical glass, on the open lower end of which an adjustable damper is installed with the possibility of periodically placing a condenser in its cavity, moreover, in the cavity of the removable cylindrical cup there are thermoelectric modules in the form of a battery of Peltier elements and temperature sensors installed evenly along the height of the cup, while connected to the generator in voltage stabilizer, which is the output unit of the wind turbine, is connected to one of the inputs of the microcontroller, to the other input of which the outputs of temperature sensors are connected, and its output is connected to the power supply of the Peltier elements to change the current value and, accordingly, the degree of cooling of the refrigerant in the cavity of the removable U-shaped cylindrical glass until reaching a temperature value that ensures the stabilization of the operation of the evaporation and condensation cycle of the refrigerant.

EFFECT: integration of the use of a mobile alternative source of electricity with simultaneous temperature control of thermoelectric modules depending on the climatic temperature in real time and optimization of the refrigerant temperature with the provision of seasonal use of permanently installed thermosiphons.
