[0018] Beneficial effects:

[0019] 1. By setting up a geothermal collection device, the energy pile is buried in the reserved foundation pit in advance, and concrete piles are poured on the upper side of the side wall of the heat collection pipe. The refrigerant needed to absorb the geothermal layer is added to the refrigerant storage tank. During the working process, the air in the heat collection pipe is extracted by a vacuum pump to make it a vacuum state. Refrigerant is added to the heat collection pipe through the refrigerant storage tank. The refrigerant gradually changes into a steam state under the influence of geothermal heat. The steam is compressed by a steam compressor to become high-temperature and high-pressure steam that enters the serpentine coil to heat the heat medium in the heat exchange tube. The generated heat will enter the energy storage device through the steam pipe. Concrete piles are set on the side wall of the heat collection pipe, which can provide good support. At the same time, the heat collection pipe is used to collect geothermal energy and the collected heat is preliminarily converted, effectively improving the utilization rate of resources.

[0020] 2. By setting up an energy storage device, the steam generated by the heat medium is injected into the two connecting pipes through two connecting pipes. At this time, the high-temperature steam is injected into the four piston sleeves, thereby pushing the four pistons to slide in the piston sleeves, so that the two turntables rotate, thereby driving the turntable to rotate, and the collected heat is converted between the piston and the piston sleeve, which can preliminarily convert thermal energy into mechanical energy, providing convenience for energy storage.

[0021] 3. By setting up an antifreeze device, the second pulley rotates under the drive of the belt, and the generator is used to generate electricity, and the electric energy is stored in the battery. In winter and rainy and snowy weather, the battery is discharged, and the electric energy is transmitted to the electric heating tube by cable. As the temperature of the electric heating tube rises, the asphalt road surface can be heated, and the snow or frozen road surface can be melted. After the mechanical energy is converted into electrical energy for storage, snow melting and anti-icing operations can be carried out in time in rainy and snowy weather, effectively reducing the operating cost of road snow removal in winter.
