There is room for optimization. Therefore, it is necessary to design a solar-based soil temperature regulation device to solve the problems mentioned above. Utility Model Content

Each end of a temperature-regulating pipe is connected to a third connecting pipe and a seventh connecting pipe, respectively. A solar collector, a radiator, and an insulated water tank are installed on one side of each temperature-regulating pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the solar-based soil temperature regulating device realizes the function of easy temperature regulation;

[0015] By arranging temperature-regulating pipes in parallel in the tillage layer, using solar collectors on the outside to absorb light energy and convert it into heat energy, and installing temperature sensors in the soil to control the temperature, while connecting the ends of the third and seventh connecting pipes to three-way solenoid valves, which are used to switch between the heat dissipation circuit and the heating circuit, so that it can actively dissipate heat when the soil temperature is too high, thereby avoiding the impact of excessive soil heat on crop growth in summer and improving the protection effect on crops.

[0016] During the heat collection phase, the solar collector heats the working medium, such as water or antifreeze. When the average soil temperature is <10℃, it enters heating mode. The first and second three-way solenoid valves switch the heating circuit, activating the first pump to deliver the medium from the temperature-regulating pipe to the solar collector. After heating, the medium is delivered to the insulated water tank. The heat is then transferred via the third pump and the seventh connecting pipe to the parallel underground temperature-regulating pipes for further heating. When the soil temperature exceeds 25℃, the temperature sensor uploads data to the controller. The controller shuts down the first and third pumps and switches the first and second three-way solenoid valves to the heat dissipation circuit. The second pump drives the working medium through the radiator for cooling. When the soil temperature falls below a certain preset value, the heat dissipation mode is exited, and normal operation is restored. This is achieved through the design of the three-way solenoid valves and the heat dissipation circuit. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1-5 The present invention provides the following technical solution:

[0026] Example 1: To address the problems in the prior art, the following solution is disclosed, specifically as follows: Figure 1As shown, the solar-powered soil temperature regulation device provided in this application includes a temperature regulating pipe 19 and a temperature sensor 20. A temperature sensor 20 is fixed to one side of each temperature regulating pipe 19. The temperature regulating pipes 19 are connected by a connecting pipe 21. A third connecting pipe 5 and a seventh connecting pipe 13 are connected to both ends of each temperature regulating pipe 19, respectively. A solar collector 1, a radiator 10, and an insulated water tank 17 are installed on one side of each temperature regulating pipe 19. One end of the third connecting pipe 5 is connected to a second connecting pipe 4 and a fourth connecting pipe 7 via a first three-way solenoid valve 6. The outer side of the second connecting pipe 4 is connected to a first connecting pipe 2 via a first pump body 3. Connecting pipe 2 is connected to solar collector 1. The outer side of the fourth connecting pipe 7 is connected to the fifth connecting pipe 9 through the second pump body 8. The outer side of the fifth connecting pipe 9 is connected to the radiator 10. One side of the radiator 10 is connected to the second three-way solenoid valve 12 through the sixth connecting pipe 11. One side of the second three-way solenoid valve 12 is connected to the seventh connecting pipe 13. One side of the insulated water tank 17 is connected to the solar collector 1 through the tenth connecting pipe 18. The other side of the insulated water tank 17 is connected to the third pump body 15 through the ninth connecting pipe 16. One side of the third pump body 15 is connected to the second three-way solenoid valve 12 through the eighth connecting pipe 14.

[0027] In this embodiment, during use, temperature regulating pipes 19 are arranged in parallel in the tillage layer, and solar collectors 1 are used on the outside to absorb light energy and convert it into heat energy. Temperature sensors 20 are installed in the soil to control the temperature. At the same time, three-way solenoid valves are connected to the ends of the third connecting pipe 5 and the seventh connecting pipe 13 to switch between the heat dissipation circuit and the heating circuit, so that the soil temperature can actively dissipate heat when it is too high, thereby avoiding the impact of excessive soil heat on crop growth in summer and improving the protection effect on crops.

[0028] During the heat collection phase, the solar collector 1 heats the working medium, such as water or antifreeze. Subsequently, when the average soil temperature is <10℃, it enters the heating mode. The first three-way solenoid valve 6 and the second three-way solenoid valve 12 switch the heating circuit, start the first pump body 3 to transport the medium in the temperature regulating pipe 19 to the solar collector 1, and after heating, it is transported to the heat-insulating water tank 17. The heat is then transported to the underground parallel temperature regulating pipe 19 for heating via the third pump body 15 and the seventh connecting pipe 13. When the soil temperature is >25℃, the temperature sensor 20 uploads data to the controller. The controller shuts down the first pump body 3 and the third pump body 15, and switches the first three-way solenoid valve 6 and the second three-way solenoid valve 12 to the heat dissipation circuit. The second pump body 8 drives the working medium to flow through the radiator 10 for cooling. When the soil temperature is less than a certain preset value, the heat dissipation mode is exited, and the normal state is restored. This is achieved through the design of the three-way solenoid valve and the heat dissipation circuit.

[0029] Example 2: This example, based on Example 1, incorporates a cleaning mechanism to prevent heat collection attenuation. Specifically, as follows... Figures 1-5As shown, a first mounting base 22 and a second mounting base 24 are fixed to the two sides of the top of the solar collector 1, respectively. A movable plate 29 is connected between the first mounting base 22 and the second mounting base 24. A cleaning brush plate 32 is connected to the bottom of the movable plate 29. Mounting blocks 33 are evenly fixed to the top of the cleaning brush plate 32. Mounting grooves 31 are evenly provided at the bottom of the movable plate 29, and each mounting groove 31 is connected to a mounting block 33. The width of each mounting groove 31 matches the width of the mounting block 33. The cross-sections of both the mounting groove 31 and the mounting block 33 are T-shaped. The mounting base 22 is internally connected to a threaded rod 25, and the outer side of the threaded rod 25 is threadedly connected to a threaded sleeve 26. The inner side of the threaded sleeve 26 is connected to the movable plate 29. A motor 23 is fixed on one side of the first mounting base 22, and the output shaft of the motor 23 is connected to the threaded rod 25. The second mounting base 24 is internally provided with a guide groove 27, and a guide block 28 is movably connected inside the guide groove 27. The inner side of the guide block 28 is connected to the movable plate 29. The top of each mounting block 33 is provided with a screw hole 34, and a bolt 30 is threadedly connected inside each screw hole 34.

[0030] In this embodiment, during use, the starting motor 23 drives the threaded rod 25 to rotate. Under the action of the threaded connection, the threaded sleeve 26 drives the moving plate 29 to move, which drives the cleaning brush plate 32 to clean the surface of the solar collector 1 to reduce dust accumulation. This ensures the performance of the solar collector 1, avoids heat collection attenuation, and reduces the time and labor required for manual cleaning, thereby improving work efficiency.
