In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0025] The present embodiment relates to an above-ground outdoor fire water tank that combines solar energy and geothermal energy for anti-freezing. The solar cell panel 1 and the electric heating circuit 2 can be provided to supplement the heat for the soil to achieve the thermal balance of the soil. The surrounding soil and the water in the fire water tank body 5 are used to store heat to increase the overall thermal inertia and improve the anti-freezing effect.
[0026] Based on the above-mentioned design concept, an exemplary structure of an above-ground outdoor fire water tank with combined antifreeze of solar energy and geothermal energy in this embodiment is as follows: Figure 1 As shown, it mainly includes a fire water tank body 5, an insulation layer 4 is provided on the outside of the fire water tank body 5, an above-ground coil 3 is provided between the insulation layer 4 and the fire water tank body 5, the above-ground coil 3 is connected to an underground coil 6 buried deep in the soil, an electric heating circuit 2 is provided on the outer wall of the underground coil 6, the electric heating circuit 2 is wound around the outer wall of the underground coil 6, the electric heating circuit 2 extends upward and is connected to a solar cell panel 1, the solar cell panel 1 is located above the fire water tank body 5 and connected to the fire water tank body 5; the above-ground coil 3 and the underground coil 6 are filled with heat medium.
[0027] The heat medium inside the above-ground coil 3 and the underground coil 6 is antifreeze liquid; the above-ground coil 3 and the underground coil 6 together form an antifreeze liquid heating circulation loop.
[0028] The above-ground outdoor fire water tank with combined solar energy and geothermal energy for antifreeze described in this embodiment is in a pure geothermal natural circulation condition when in use. On winter nights when there is no sun, the antifreeze is first heated by the surrounding soil in the underground coil 6, and its volume increases and its density decreases, generating an upward buoyancy force, and then it enters the above-ground coil 3 around the fire water tank body 5 and is cooled, and its volume decreases and its density increases, and it sinks back into the underground coil 6. During the natural circulation of the antifreeze, geothermal energy is continuously transferred to the fire water tank body 5 to prevent ice from forming inside the fire water tank body.
[0029] When in the solar power generation and heat storage cycle, during the daytime when there is sunshine, the solar panel 1 absorbs solar energy to generate electricity, which is directly used to heat the underground coil 6, the antifreeze in the coil and the soil around the coil through the electric heating circuit 2, accelerating the circulation of the antifreeze pipeline, and the temperature of the fire water pool in the fire water tank body 5 rises rapidly. Part of the solar energy generated is used to compensate for the soil energy loss caused by taking heat from the soil at night, achieving energy balance, and preparing for the next "pure geothermal natural circulation condition". On the other hand, the excess solar energy is used to increase the water temperature of the fire water pool. The fire water pool and the surrounding soil both play a role in heat storage, replacing the disadvantage of the traditional solar energy system that requires a large number of batteries. The system structure is simple and the effect is significant.
[0030] The above-ground outdoor fire water tank with combined solar energy and geothermal energy for antifreeze of the above-mentioned implementation scheme achieves the purpose of heat exchange for the water tank through the natural circulation of antifreeze liquid in the heating circulation pipeline. The system is simple and saves operating costs. The solar cell panel 1 is provided in conjunction with the electric heating circuit 2 to supplement the heat for the soil and achieve the thermal balance of the soil. The surrounding soil and the water in the fire water tank body 5 are used to store heat, thereby increasing the overall thermal inertia and improving the antifreeze effect.
[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
