[0025] In order to better understand the technical content of the present invention, a specific embodiment is provided below, and the present invention will be further described in conjunction with the accompanying drawings.

[0026] See Figures 1 to 4, a condensate irrigation system based on photovoltaic waste heat recovery provided by the present invention includes a photovoltaic panel 1, a waste heat exchanger 2, a honeycomb heat storage ceramic 3, a cover plate 4, and a condensate irrigation mechanism. The waste heat exchanger 2 is arranged on the back of the photovoltaic panel 1. The honeycomb heat storage ceramic 3 is located on one side of the waste heat exchanger 2. The cover plate 4 is arranged on the top surface of the honeycomb heat storage ceramic 3. The condensate irrigation mechanism includes a water storage tank 5, a first electric push rod 6, a condensate coil 7, a cooling box 8, a water pump 9, a circulation pipe 10, a blower 11, a water delivery pipe 12, a drip irrigation pipe 13, and a drip head 14. The water storage tank 5 is located below the photovoltaic panel 1 and is provided with a through slot 15. The first electric push rod 6 is arranged in the water storage tank 5, and its output shaft passes through the through slot 15 and is connected to the bottom surface of the honeycomb heat storage ceramic 3. The condensate coil 7 is located in the water storage tank 5. The cooling box 8 is arranged on the inner top surface of the water storage tank 5. The water pump 9 is arranged on both sides of the cooling box 8. One end of the circulation pipe 10 is connected to the water pump 9, and the other end is connected to one end of the condensate coil 7. The blower 11 is arranged on the side wall of the water storage tank 5 and is located on one side of the moving path of the honeycomb heat storage ceramic 3. One end of the water delivery pipe 12 is connected to the bottom surface of the water storage tank 5, and the other end extends to one side. The drip irrigation pipes 13 are arranged at intervals on the water delivery pipe 12. The drip heads 14 are arranged at the bottom ends of the drip irrigation pipes 13.

[0027] The condensate irrigation system based on photovoltaic waste heat recovery of the present invention combines photovoltaic, air water intake, and drip irrigation. The photovoltaic panel 1 is used to absorb solar energy and convert it into electrical energy for the power equipment in the system. During the power generation process of the photovoltaic panel 1, a large amount of waste heat will be generated on its back. In traditional power generation modules, most of this waste heat is directly dissipated into the environment, resulting in energy waste. In the present invention, a waste heat exchanger 2 is arranged on the back of the photovoltaic panel 1. The waste heat exchanger 2 is composed of aluminum alloy fins and copper microchannel tubes and is seamlessly bonded to the back of the photovoltaic panel 1 using thermal conductive silicone. The heat generated by the photovoltaic panel 1 can be transferred downward by the waste heat exchanger 2. A liftable honeycomb heat storage ceramic 3 is arranged on one side of the waste heat exchanger 2 to store the heat transferred by the waste heat exchanger 2. After the heat storage is completed, the first electric push rod 6 can lower the honeycomb heat storage ceramic 3 from the through slot 15 into the water storage tank 5. The cover plate 4 above the honeycomb heat storage ceramic 3 can be placed on the through slot 15 to close the through slot 15 and prevent heat from overflowing from the through slot 15. Then, in the water storage tank 5, the waste heat absorbed by the honeycomb heat storage ceramic 3 can be used for air water intake to avoid waste of thermal energy.

[0028] A blower 11 is provided on the side wall of the water storage tank 5. The blower 11 can blow external air into the water storage tank 5. The honeycomb heat storage ceramic 3 is located on one side of the blower 11. When the air passes through the honeycomb heat storage ceramic 3, it is heated. A condensing coil 7 is provided in the middle of the water storage tank 5. The water pump 9 can transport the coolant in the cooling tank 8 to the condensing coil 7 through the circulation pipe 10 on one side and flow back into the cooling tank 8 through the circulation pipe 10 on the other side to realize the circulating flow of the coolant. When the humid hot air flows through the outside of the condensing coil 7, it will exchange heat with the coolant in the condensing coil 7, and then the water vapor will liquefy and adhere to the outside of the condensing coil 7 and finally drip to the bottom of the water storage tank 5 for collection. When irrigation is required, the condensed water in the water storage tank 5 can be transported through the water delivery pipe 12. A number of drip irrigation pipes 13 installed on the water delivery pipe 12 are arranged near the plant roots and drip irrigation is realized through the drip heads 14. By effectively utilizing the waste heat, the comprehensive energy utilization efficiency of the photovoltaic equipment is improved, energy waste is reduced, and at the same time, the plants can be accurately irrigated, water resources are saved, and the planting cost is reduced.

[0029] Preferably, the condensed water irrigation mechanism further includes a filter 16, and the filter 16 is arranged inside the drip irrigation pipe 13.

[0030] The filter 16 is used to filter impurities and the like to prevent the drip irrigation pipe 13 and the drip head 14 from being blocked and ensure normal plant irrigation.

[0031] Preferably, the condensed water irrigation mechanism further includes a sensor group and a regulating valve 17. The sensor group is used to monitor the environmental humidity, soil moisture content and plant growth status, and the regulating valve 17 is arranged on the water delivery pipe 12.

[0032] The sensor group is distributed at multiple positions in the planting process. For example, it is installed in the planting greenhouse to detect the environmental humidity in the planting greenhouse. A moisture sensor can also be installed in the soil where the plants are planted to detect the soil moisture. When the soil is short of water, drip irrigation can be carried out in time. Or by monitoring the growth status of the plants, when the plants grow relatively slowly, the drip irrigation amount can be increased or decreased. The regulating valve 17 can control the water output to realize the automatic regulation of irrigation.

[0033] Preferably, a condensation enhancement mechanism is further included. The condensation enhancement mechanism includes Fe3O4 magnetic fluid 18, a first linear guide rail 19, a second linear guide rail 20, an electromagnet 21, and a recovery and circulation mechanism. The Fe3O4 magnetic fluid 18 is located inside the condensation coil 7. Both ends of the first linear guide rail 19 are connected to the inner side wall of the water storage tank 5. The bottom surfaces of both ends of the second linear guide rail 20 are connected to the top surface of the mover of the first linear guide rail 19. The electromagnet 21 is arranged on the top surface of the mover of the second linear guide rail 20 and is located below the condensation coil 7. The electromagnet 21 is used to drive the Fe3O4 magnetic fluid 18 to flow in the condensation coil 7. The recovery and circulation mechanism is used to recover the Fe3O4 magnetic fluid 18 from one side of the condensation coil 7 to the other side for circulating flow.

[0034] In order to improve the heat exchange efficiency between the coolant and the hot air, the present invention injects Fe3O4 magnetic fluid 18 into the condensation coil 7, and at the same time, an electromagnet 21 driven to move by the first linear guide rail 19 and the second linear guide rail 20 is arranged below the condensation coil 7. The electromagnet 21 can apply a magnetic force to the Fe3O4 magnetic fluid 18 to change its flow velocity in the condensation coil 7, which can promote the coolant to generate a more complex flow pattern, enhance the turbulence degree of the fluid, make the heat transfer between the coolant and the object to be cooled more sufficient, reduce the boundary layer thermal resistance, and thus improve the cooling efficiency. The moving directions of the movers of the first linear guide rail 19 and the second linear guide rail 20 are perpendicular, so the electromagnet 21 can move along the shape of the condensation coil 7 to enable the Fe3O4 magnetic fluid 18 to flow along the condensation coil 7.

[0035] Preferably, the recovery and circulation mechanism includes a first vertical pipe 22, a second vertical pipe 23, a connecting pipe 24, a gate valve 25, a lifting plate 26, a bracket 27, and a second electric push rod 28. The first vertical pipe 22 is arranged on the bottom surface of the water inlet end of the condensation coil 7. The second vertical pipe 23 is arranged on the bottom surface of the water outlet pipe of the condensation coil 7. The connecting pipe 24 connects the side wall of the first vertical pipe 22 and the side wall of the second vertical pipe 23. The gate valve 25 is arranged at the connection between the first vertical pipe 22 and the second vertical pipe 23 and the condensation coil 7. The lifting plate 26 is embedded in the bottom surface of the first vertical pipe 22. The bracket 27 is arranged on the bottom surface of the first vertical pipe 22. The second electric push rod 28 is arranged on the bracket 27, and its output shaft is connected to the bottom surface of the lifting plate 26.

[0036] The Fe3O4 magnetic fluid 18 will move from the water inlet end to the water outlet end of the condensation coil 7. Then, the sluice valve 25 at the second vertical pipe 23 can be opened, and the magnitude of the current supplied to the electromagnet 21 can be increased. The electromagnet 21 magnetically attracts the Fe3O4 magnetic fluid 18, and after a part of the coolant flows downward, it enters the second vertical pipe 23. Then, the sluice valve 25 is closed. At this time, the Fe3O4 magnetic fluid 18 can enter the connecting pipe 24 and move to the lifting plate 26 of the first vertical pipe 22 driven by the electromagnet 21. Finally, the second electric push rod 28 can drive the lifting plate 26 to rise. After the sluice valve 25 is opened, the Fe3O4 magnetic fluid 18 is pushed into the condensation coil 7, so that the Fe3O4 magnetic fluid 18 returns to its initial position. Thus, the Fe3O4 magnetic fluid 18 can circulate repeatedly, prompting the coolant to generate a more complex flow pattern.

[0037] Preferably, the recycling mechanism includes a sealing ring 29, and the sealing ring 29 is sleeved on the side wall of the lifting plate 26.

[0038] The provided sealing ring 29 can prevent the liquid in the connecting pipe 24 from overflowing from the bottom end of the first vertical pipe 22. At the same time, when the lifting plate 26 rises to the position of the sluice valve 25, it can also prevent the coolant in the condensation coil 7 from entering the first vertical pipe 22.

[0039] Preferably, the recycling mechanism further includes a filter screen 30, and the filter screen 30 is arranged at the connection between the water outlet end of the condensation coil 7 and the circulation pipe 10 and is located above the second vertical pipe 23.

[0040] The provided filter screen 30 can prevent the Fe3O4 magnetic fluid 18 from entering the circulation pipe 10 from the filter screen 30 when the water pump 9 extracts the coolant in the condensation coil 7, reducing the loss of the Fe3O4 magnetic fluid 18.

[0041] Refer to Figures 5-6Another embodiment is shown. The water delivery pipe 12 includes a front pipe 31, an irrigation pipe 32, a docking mechanism, a mounting frame 33, an electric turntable 34, a rotating cylinder 35, a fixing frame 36, a release pipe 37, a porous filter cartridge 38, and several different types of mineral particles 39. One end of the front pipe 31 is connected to the bottom surface of the water storage tank 5, and the other end extends to one side. The irrigation pipe 32 is arranged on one side of the end of the front pipe 31 away from the water storage tank 5, and a docking station 40 is formed between the irrigation pipe 32 and the front pipe 31. The docking mechanism is arranged on the opposite ends of the front pipe 31 and the irrigation pipe 32. The mounting frame 33 straddles the front pipe 31 and the irrigation pipe 32 respectively. The electric turntable 34 is arranged on the mounting frame 33 and is arranged oppositely. Both ends of the rotating cylinder 35 are connected to the rotating surface of the electric turntable 34 and are located above the docking station 40.

The porous filter cartridge 38 is arranged in the release pipe 37. The mineral particles 39 are located in the porous filter cartridge 38. The mineral particles 39 in different porous filter cartridges 38 are different. The docking mechanism is used to dock with the end of the release pipe 37.

[0042] In order to ensure that the condensed water delivered to the plants can be rich in the required minerals, this embodiment makes a special design for the water delivery pipe 12. The water delivery pipe 12 is designed in a three-section form, which are the front pipe 31, the release pipe 37, and the irrigation pipe 32 in sequence according to the water flow direction. The electric turntable 34 on the mounting frame 33 can drive the rotating cylinder 35 to rotate, so as to drive the release pipe 37 to rotate through the fixing frame 36. There are multiple release pipes 37 arranged on the rotating cylinder 35, and different release pipes 37 can rotate to the docking station 40. Then, through the docking mechanism, both ends of the release pipe 37 can be docked with the front pipe 31 and the irrigation pipe 32 respectively, so as to form a complete water flow path. After the condensed water in the front pipe 31 flows into the release pipe 37, it will flow through the porous filter cartridge 38 and contact the mineral particles 39 in the porous filter cartridge 38, carry the minerals in the mineral particles 39 and then irrigate the plants, simulating the groundwater mineralization process. For example, when the mineral particles 39 are basalt debris, it can increase trace elements such as calcium and magnesium in the water, improve the irrigation water quality, and reduce the cost of traditional mineral additives.

[0043] Preferably, the docking mechanism includes a corrugated pipe 41, a movable pipe 42, a side plate 43, and a third electric push rod 44. The corrugated pipe 41 is arranged on the opposite side walls of the front pipe 31 and the irrigation pipe 32. The movable pipe 42 is connected to the corrugated pipe 41. The side plate 43 is arranged on the side wall of the movable pipe 42. The third electric push rod 44 is arranged on the outer walls of the front pipe 31 and the irrigation pipe 32, and its output shaft is connected to the side wall of the side plate 43. The outer diameter of the movable pipe 42 is smaller than the inner diameter of the release pipe 37. The docking mechanism further includes a rubber ring 45, and the rubber ring 45 is arranged on the outer wall of the movable pipe 42.

[0044] When docking, the third electric push rod 44 drives the corrugated pipe 41 to expand and contract through the side plate 43. After the moving pipe 42 moves, it is inserted into the inside of the release pipe 37 to achieve docking, so that the condensed water can be conveyed. The rubber ring 45 provided can seal the connection position between the moving pipe 42 and the release pipe 37 to prevent the condensed water from overflowing.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
