[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, a geothermal heating system for a greenhouse includes a solar collector 1, a water storage tank 2, and geothermal coils 3. The solar collector 1 is vertically installed on the back wall of the greenhouse, the water storage tank 2 is located on the outside of the greenhouse, and the geothermal coils 3 are located below the ground of the greenhouse.

[0027] like Figure 1 As shown, the lower end of the water storage tank 2 is provided with a water supply pipe 4 that connects to one end of the geothermal coil 3, and the upper end is provided with a return water pipe 5 that connects to the other end of the geothermal coil 3. A water supply circulation pump 6 is installed on the water supply pipe 4.

[0028] like Figure 1 As shown, the lower end of the water storage tank 2 is provided with an inlet pipe 7 that connects to the lower end of the solar collector 1, and the upper end is provided with an outlet pipe 8 that connects to the upper end of the solar collector 1. An inlet circulation pump 9 is provided on the inlet pipe 7.

[0029] During the day, the cold water in the water storage tank 2 is injected into the solar collector 1 by the water circulation pump 9 to heat the cold water. Then the hot water is discharged into the water storage tank 2, so that the water storage tank 2 stores a large amount of hot water for use at night.

[0030] At night, the hot water in the water storage tank 2 is injected into the geothermal coil 3 by the water supply circulation pump 6 to heat the ground soil. The used cold water then flows back into the water storage tank 2, and the cycle continues to heat the ground soil.

[0031] Therefore, by setting up a solar collector 1, solar energy is used to heat the water source and store it in a water storage tank 2. The hot water can then be transported to the geothermal coil 3 to heat the ground. This heating method is energy-saving and environmentally friendly, and can reduce the waste of resources.

[0032] like Figure 1 , Figure 2As shown, the water storage tank 2 includes a base 21, a top seat 22, an inner lining 23, an outer sleeve 24, and an insulation layer 25. The base 21 and the top seat 22 are both horizontally arranged, the inner lining 23 and the outer sleeve 24 are arranged between the base 21 and the top seat 22, and the insulation layer 25 is arranged between the inner lining 23 and the outer sleeve 24.

[0033] like Figure 1 , Figure 2 As shown, both the base 21 and the top seat 22 are provided with mounting rings 26 located between the inner liner 23 and the outer sleeve 24. Both the inner liner 23 and the outer sleeve 24 are provided with retaining rings 261. The mounting rings 26 are provided with slots 262 for the retaining rings 261 to be inserted.

[0034] like Figure 1 , Figure 2 As shown, the inner wall of the lining 23 is provided with a heating wire 27, which can realize auxiliary heating of the water source in the water storage tank 2 and meet the usage requirements of the geothermal coil 3.

[0035] like Figure 1 , Figure 2 As shown, a U-shaped cleaning rod 28 is provided inside the liner 23. The cleaning rod 28 abuts against the inner wall of the liner 23, the base 21 and the top seat 22. A drain port 29 is provided on the base 21.

[0036] After prolonged use, the motor can be controlled to rotate, thereby driving the cleaning rod 28 to rotate and clean the inner wall of the water tank 2. This allows the wastewater to be discharged through the drain outlet 29, ensuring the cleanliness of the inner wall of the water tank 2 and guaranteeing the cleanliness of the water tank 2 and the entire heating system.

[0037] like Figure 1 , Figure 3 As shown, the solar collector 1 includes a support frame 11 and a collector plate 12. The support frame 11 is vertically arranged in an L-shape. The upper end of the collector plate 12 is rotatably connected to a slider 13. The slider 13 is vertically slidably connected to the support frame 11. The slider 13 is threaded with a screw 14 that presses the support frame 11.

[0038] like Figure 1 , Figure 3 As shown, a drive block 15 is rotatably connected to the lower end of the heat collection plate 12. The drive block 15 is horizontally slidably connected to the support frame 11. A screw 16 is horizontally rotatably connected to the support frame 11. The screw 16 is threadedly connected to the drive block 15.

[0039] When installing the solar collector 1, the support frame 11 is fixed to the back wall, and then the screw 14 is loosened. The screw 16 is then rotated, causing the drive block 15 to slide horizontally on the support frame 11. At this time, the drive block 15 drives the collector plate 12 to move synchronously, achieving angle adjustment of the collector plate 12. Finally, the screw 14 is tightened to fix the slider 13, completing the secondary locking of the collector plate 12. This ensures that the collector plate 12 can receive direct sunlight and meet the installation requirements of different locations.

[0040] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
