[0021] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The following will refer to the accompanying drawings Figures 1 - 3 and describe the present utility model in detail in combination with the embodiments.

[0022] An environment-friendly anti-freezing device for water conservancy and hydropower equipment, including an air source heat pump 1 and a solar panel 2. The air source heat pump 1 and the solar panel 2 are connected to a water tank 3. A spiral heat exchange tube 4 and a heating coil 5 are arranged inside the water tank 3. An inlet 12 and an outlet 13 penetrate through the top wall and the bottom end of the side wall of the water tank 3. Support blocks 14 are fixedly arranged symmetrically up and down inside the water tank 3 to support the spiral heat exchange tube 4, and the spiral heat exchange tube 4 is fixedly arranged between the support blocks 14.

[0023] The heating coil 5 is arranged around the outer periphery of the spiral heat exchange tube 4, and the heating coil 5 is fixedly connected to the side wall of the water tank 3 through a plurality of connecting rods. Water enters the inside of the water tank 3 from the inlet 12, and after several cycles of hot water and cold water, the sewage is discharged from the outlet 13.

[0024] The spiral heat exchange tube 4 and the solar panel 2 are connected through a heat supply pipe 6 and a return pipe 7. One end of the heat supply pipe 6 is connected to the top end of the spiral heat exchange tube 4, and the other end is connected to the heat supply end of the solar panel 2. One end of the return pipe 7 is connected to the bottom end of the spiral heat exchange tube 4, and the other end is connected to the return end of the solar panel 2. Pumps 18 are arranged on both the heat supply pipe 6 and the return pipe 7.

[0025] When using the solar panel 2 for heat supply, the pump 18 is started, so that the heat absorption medium inside the solar panel 2 enters the heat supply pipe 6 from the heat supply end, and enters the spiral heat exchange tube 4 along the way. During the process of flowing down along the spiral heat exchange tube 4, it exchanges heat with the cold water inside the water tank 3. After the heat exchange, the low-temperature heat absorption medium returns to the inside of the solar panel 2 from the return pipe 7 to absorb heat from the sun again. In this way, the cycle heat supply of the solar panel 2 is realized, so that the water inside the water tank 3 is heated and raised in temperature.

[0026] The air source heat pump 1 is connected to the heating coil 5, and the air source heat pump 1 can make the heating coil 5 play a heating role. When the solar energy is insufficient, it needs to be converted to the air source heat pump 1 for heat supply. Since the air source heat pump is an energy-saving device that uses high-level energy to make heat flow from a low-level heat source (such as air, soil, heat contained in water) to a high-level heat source, it can convert the low-level heat energy that cannot be directly utilized into high-level heat energy that can be utilized, so as to achieve the purpose of saving some high-level energy (such as coal, gas, oil, electric energy, etc.). Therefore, when the air source heat pump 1 transfers heat energy to the heating coil 5 and then heats the water, it is also an environment-friendly way to save energy, which is more resource-saving than traditional electric energy.

[0027] There is an equipment box 9 arranged beside the water tank 3. The equipment box 9 is a box body with an upward opening. A detachable upper cover 15 is movably arranged at the opening, which facilitates the storage and retrieval of equipment. One end of the upper cover 15 is rotatably arranged at the top of the equipment box 9 through a hinge, and the other end can be set as a commonly used buckle fastening device in the prior art, so that the upper cover 15 is detachably rotatably arranged at the top of the equipment box 9, facilitating the placement of water conservancy and hydropower equipment into the interior of the equipment box 9 or the retrieval from the interior of the equipment box 9.

[0028] The bottom wall and side walls of the equipment box 9 are sequentially provided with a heating layer 10 and a heat insulation layer 11 from the inside to the outside. The water tank 3 is communicated with the heating layer 10 through a conveying pipe 8. The conveying pipe 8 includes a hot water conveying pipe 16 and a cold water conveying pipe 17. The heating layer 10 is a cavity, the top of the cavity is communicated with the hot water conveying pipe 16, and the bottom of the cavity is communicated with the cold water conveying pipe 17. Pump bodies 18 are arranged on both the hot water conveying pipe 16 and the cold water conveying pipe 17.

[0029] Start the pump body 18 in the hot water conveying pipe 16, so that hot water can flow from the water tank 3 along the hot water conveying pipe 16 into the cavity of the heating layer 10. The heat of the hot water is transmitted along the inner wall of the cavity to the interior of the equipment box 9, preventing the water conservancy and hydropower equipment from being frozen in low-temperature weather and affecting its use. The heat insulation layer 11 is filled with heat insulation material glass wool, which can play a role in heat preservation for the heat inside the heating layer 10 and prevent the heat from losing too quickly.

[0030] When the water temperature drops, start the pump body 18 in the cold water conveying pipe 17, so that the cold water returns from the cold water conveying pipe 17 to the water tank 3 for heating. In this way, the anti-freezing purpose of the equipment box 9 is achieved through such a cycle. Moreover, it is not limited to this. If the production cost of the device is not considered, a temperature sensor can be used to accurately control the temperature. In cooperation with a control system, the above process can be preset in the control system, and in cooperation with the temperature sensor, the temperature can be automatically controlled to prevent the water conservancy and hydropower equipment from being frozen by low temperature.

[0031] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
