[0033] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0034] Example 1

[0035] like Figure 1-3 As shown, a solar-powered, electrically heated air-injected soil borehole condensate collection, pumping, and drip irrigation system for vegetation restoration includes a solar power supply system, a high-temperature air circulation system, a low-temperature condensate return system, a pumping and collection system, and a drip irrigation system.

[0036] Low-temperature reflux condensate system uses temperature difference to condense water vapor in the air into water;

[0037] Among them, such as Figure 1 As shown, the low-temperature reflux condensate system includes multiple soil hole pipes 4, each of which has an air inlet for air entry. The multiple soil hole pipes 4 are preferably buried underground.

[0038] Here, the soil hole pipe 4 can be designed with different lengths and diameters, preferably a metal cylindrical structure, to adapt to different soil conditions and depths.

[0039] The high-temperature air circulation system is used to heat the air and then input the heated air into the low-temperature reflux condensate system.

[0040] Here, by heating the air, the temperature difference between the hot and cold air in the low-temperature reflux condensate system can be increased;

[0041] Among them, such as Figure 1-3 As shown, the high-temperature air circulation system includes an electric heating box 3 that is electrically connected to a solar power supply system. The electric heating box 3 is preferably located on the ground. The exhaust end of the electric heating box 3 is fixedly connected to a duct 5. The duct 5 is fixedly connected to a number of air guide branches equal to the number of soil hole pipes 4. The multiple air guide branches are respectively connected to the air inlets of multiple soil hole pipes 4. At this time, the air is heated by the electric heating box 3, and then the hot air is input into the interior of the soil hole pipes 4 through the duct 5, thus completing the input of hot air.

[0042] like Figure 3 As shown, a buoyancy block 21 is installed inside the soil hole pipe 4, and a small condenser 22 is fixedly connected to the upper side of the buoyancy block 21. The small condenser 22 is electrically connected to the solar power supply system.

[0043] At this time, when condensation occurs inside the soil hole pipe 4, the condensation forms a water accumulation section 20 at the lower end of the soil hole pipe 4. Since the hot air is only located inside the soil hole pipe 4 and in the empty area above the water accumulation section 20, cooling the water accumulation section 20 at the lower end of the soil hole pipe 4 cannot condense the hot air into condensation. When producing condensation, it is only necessary to cool the empty area of ​​the soil hole pipe 4, so that the cold energy can be concentrated to cool the hot air and reduce energy waste.

[0044] The upper side of the buoyancy block 21 is fixedly connected to a sleeve 23, and a connecting rod 24 is vertically slidably connected inside the sleeve 23. The small condenser 22 is fixedly connected to the upper end of the connecting rod 24, and a locking screw 19 is threadedly connected to the upper end of the sleeve 23. At this time, the height of the small condenser 22 can be adjusted by sliding the connecting rod 24. After the adjustment is completed, the small condenser 22 can be locked by locking the locking screw 19, so that the height of the small condenser 22 from the liquid surface of the water accumulation part 20 can be adjusted.

[0045] like Figure 1-2 As shown, the electric heating box 3 includes a box body 15. An electric heating tube 16 is fixedly connected inside the box body 15. A second fan 17 is fixedly connected to the air inlet end of the box body 15. The air duct 5 is connected to the exhaust end of the box body 15. The electric heating tube 16 and the second fan 17 are both electrically connected to the solar power supply system. At this time, by starting the second fan 17, air can be blown into the box body 15. Then, the electric heating tube 16 can heat the flowing air. After heating, the air can be output through the air duct 5. The arrangement of the electric heating tube 16 and the second fan 17 can ensure sufficient supply of hot air.

[0046] Furthermore, a first fan 6 is fixedly connected between the air duct branch pipe and the air inlet of the soil hole pipe 4. The first fan 6 is electrically connected to the solar power supply system. The first fan 6 blows hot air, which can further promote the flow of hot air.

[0047] The pumping and collection system is used to extract and collect condensate from the low-temperature reflux condensate system;

[0048] like Figure 1As shown, the pumping and collection system includes a water tank 10 and a first water pump 8. The first water pump 8 is electrically connected to a solar power supply system. The water tank 10 is preferably buried near the ground surface. It can be a sealed container or a container with an open top. The first water pump 8 can be fixedly connected to the water tank 10 or fixed to the ground. The input end of the first water pump 8 is fixedly connected to a main water pipe 7. Multiple water branch pipes 14 are fixedly connected to the main water pipe 7. The multiple water branch pipes 14 extend to the bottom of the interior of multiple soil hole pipes 4. The buoyancy block 21 can be slidably connected to the outside of the water branch pipe 14. The water branch pipe 14 can guide the buoyancy block 21. The output end of the first water pump 8 is fixedly connected to an inlet pipe 9 extending into the interior of the water tank 10. When the first water pump 8 is started, it can pump out the condensate inside the soil hole pipes 4 through the main water pipe 7 and the water branch pipes 14, and then output it to the interior of the water tank 10 for collection through the inlet pipe 9.

[0049] The drip irrigation system is used to drip condensate collected in the pumping and collection system to the vegetation unit 13.

[0050] Among them, such as Figure 1 As shown, the drip irrigation system includes a second water pump 11 installed inside the water tank 10. The second water pump 11 is electrically connected to the solar power supply system. The output end of the second water pump 11 is fixedly connected to the drip irrigation pipeline 12. By starting the second water pump 11, the water inside the water tank 10 can be output to the vegetation unit 13 through the drip irrigation pipeline 12, thus completing the purpose of drip irrigation of the vegetation unit 13.

[0051] Here, the drip irrigation pipeline 12 includes a drip irrigation main pipe connected to the output end of the second water pump 11. Multiple drip irrigation branch pipes connected to the drip irrigation main pipe are fixedly connected to the drip irrigation main pipe. Multiple drip irrigation holes opposite to the vegetation unit 13 are opened on the drip irrigation branch pipes. The water output by the second water pump 11 will flow through the drip irrigation main pipe and the drip irrigation branch pipes to the drip irrigation holes, and then be sprayed onto the vegetation unit 13 through the drip irrigation holes.

[0052] Here, the second water pump 11 includes an automatic control system for automatically adjusting the pumping volume and water level.

[0053] The high-temperature air circulation system, water pumping and collection system, and drip irrigation system are all electrically connected to the solar power supply system, which is used to input electrical energy into the high-temperature air circulation system, water pumping and collection system, and drip irrigation system.

[0054] Among them, such as Figure 1As shown, the solar power supply system includes a solar panel 1, which is electrically connected to a solar power storage battery 2. The solar power storage battery 2 is electrically connected to a DC-to-AC power converter 18. The first fan 6, the first water pump 8, the second water pump 11, the electric heating tube 16 in the electric heating box 3, and the second fan 17 are all electrically connected to the DC-to-AC power converter 18. The solar panel 1 can convert solar energy into electrical energy and store it inside the solar power storage battery 2. Then, the DC power inside the solar power storage battery 2 is converted into AC power by the DC-to-AC power converter 18, and the electrical energy is input to the first fan 6, the first water pump 8, the second water pump 11, the electric heating tube 16, and the second fan 17, thereby reducing resource consumption.

[0058] Specifically, S1 is to start the electric heating box 3 to heat the air, and then input the hot air into the soil hole pipe 4 through the air duct 5.

[0059] S2: In a low-temperature reflux condensate system, water vapor in the air is condensed into water by utilizing the temperature difference.

[0060] Specifically, S2 utilizes the temperature difference between cold and hot air inside the soil hole pipe 4 to condense water vapor in the air into water.

[0061] S3: Start the pumping and collection system to extract and collect the condensate from the low-temperature reflux condensate system;

[0062] Specifically, S3 is to start the first water pump 8, which extracts the condensate inside the soil hole pipe 4 through the main water pipe 7 and the branch water pipe 14, and then outputs it to the water tank 10 for collection through the inlet pipe 9.

[0063] S4: Start the drip irrigation system to drip condensate collected in the pumping and collection system.

[0064] Specifically, S4 is to start the second water pump 11, which will output the water inside the water tank 10 to the vegetation unit 13 through the drip irrigation line 12, thus completing the purpose of drip irrigation of the vegetation unit 13.

[0065] This technical solution enables precise irrigation of vegetation units 13 in loess sites and ecologically deficient areas, improving water resource utilization efficiency. It also provides necessary moisture to vegetation units 13, promoting ecological restoration and environmental protection. It is applicable to arid and semi-ecologically deficient areas as well as water-scarce regions, particularly the Loess Plateau and other areas with severe soil erosion. It reduces the restriction of groundwater resources in ecologically deficient areas, increases the water supply to vegetation units 13 in loess sites, promotes vegetation unit growth, and improves the ecological environment. This is of great significance for improving the ecological environment of the Loess Plateau and promoting the restoration of vegetation units 13, and has significant practical implications for environmental restoration. By collecting water contained in the air through temperature differences, it fills a gap in vegetation unit 13 restoration methods and has significant practical implications for environmental restoration.
