Description

Technical Field

[0001] The utility model relates to the field of irrigation, in particular to a cooling device suitable for farmland aerated irrigation water. Background Art

[0002] Aerated irrigation is a new irrigation method that injects gas into the irrigation water during the process to improve the gas supply to the soil and crop roots, thereby promoting soil moisture redistribution and crop growth and development. Aerated irrigation is primarily used in fields such as farmland irrigation and landscaping. The bubbles disperse into the soil, creating pores that increase soil permeability and moisture retention, facilitating root extension and nutrient absorption. Aerated irrigation can significantly increase root length and surface area, improving crop absorption capacity and growth rate. By increasing the dissolved oxygen content in the irrigation water, it promotes the migration and leaching of salts in the soil, reducing soil salt concentration, and improving soil fertility and crop yields. It also alters soil water distribution, reducing water loss and evaporation, increasing soil water retention, and improving water and fertilizer utilization efficiency.

[0003] Traditional aerated irrigation often suffers from water temperatures that are too high. This defect reduces the solubility of gas in water, reducing the gas content in the water and reducing the effectiveness of aerated irrigation. Furthermore, high water temperatures increase the incidence of common pests and diseases such as aphids and red spiders, creating a comfortable temperature and humid environment for pests and diseases. Furthermore, high-temperature water irrigation causes water evaporation, which is not conducive to water retention in the soil and increases the risk of soil salinization. The traditional way to address these shortcomings is to use cooling towers for cooling operations. However, cooling towers occupy a large area, have low reliability, are costly, have slow cooling rates, and consume a lot of energy.

[0004] Therefore, providing a cooling device suitable for farmland aerated irrigation water with a simple structure, small footprint, low energy consumption, long service life, controllable cost, obvious cooling effect, and the ability to effectively reduce the temperature of aerated irrigation water source has broad market prospects.

[0015] The utility model has the following positive effects:

[0016] This product uses a separate transfer tank to cool the aerated irrigation water source. The cooling process utilizes semiconductor electric refrigeration to cool the water in the pipeline. The electric chiller cools the irrigation water in the water supply tank, producing chilled water that is then supplied for aerated irrigation. Compared to pre-cooled water, the cooled aerated irrigation water offers the following benefits: It increases the solubility of gases in water and the gas content, enhancing the effectiveness of aerated irrigation. Using this cooled irrigation water at a lower temperature can effectively reduce the occurrence of common pests and diseases, such as aphids and spider mites, by disrupting the warm and humid environment they thrive in. Cooled irrigation water also reduces water evaporation, retaining more water in the soil for crop utilization. Cooled irrigation water is more effectively absorbed by the soil, effectively reducing surface evaporation and alleviating soil salinization.

[0024] Specific embodiments refer to Figure 1 、 2 As shown in Figures 3 and 4, a cooling device suitable for farmland aerated irrigation water comprises a transfer water tank 1, an inlet pipe 8 and an outlet pipe 2 installed on the transfer water tank 1, a partition 14 is provided in the transfer water tank 1, a water supply tank 15 and a cold water tank 16 are provided on both sides of the partition 14, the top of the water supply tank 15 is connected with the water inlet pipe 8, and the bottom of the cold water tank 16 is connected with the outlet pipe 2, a water pump 13 is provided at the bottom of the water supply tank 15, a water pump 5 is connected to the water supply tank 15, and the water pump 5 is connected to the cold water tank 16 through the return pipe 6, and a cooling component is provided between the water pump 5 and the return pipe 6.

[0025] The water inlet pipe 8 is equipped with a water inlet solenoid valve 9 and a water inlet pump 10, while the water outlet pipe 2 is equipped with a water outlet solenoid valve 3 and a water outlet pump 4. A hole is provided in the transfer water tank 1 at the top of the water supply chamber 15, into which a cooling fan 7 is installed. The partition 14 is a plate-like structure made of a heat-insulating material. The outer wall of the partition 14 is fixedly connected to the inner wall of the transfer water tank 1, which is a square box structure.

[0026] The cooling assembly includes a cooling water tank 11. The top of the cooling water tank 11 is connected to the water pump 5, and the bottom of the cooling water tank 11 is connected to the return water pipe 6. A sealed refrigeration chamber 17 is provided in the cooling water tank 11. The cooling end 18 of the electric refrigerator 19 is installed in the sealed refrigeration chamber 17, and the heat dissipation end 12 of the electric refrigerator is provided outside the cooling water tank 11. The cooling water tank 11 is a square box structure, and an insulation layer is provided on the outside of the cooling water tank 11.

[0027] The cooling assembly includes an electric refrigerator 19, and a cooling pipe 21 is attached to the cooling end 18 of the electric refrigerator 19. The two ends of the cooling pipe 21 are respectively connected to the water pump 5 and the water return pipe 6. The cooling pipe 21 is attached to the outer surface of the cooling end 18 by gluing.

[0028] The electric refrigerator 19 is a semiconductor electric refrigerator, and the cooling end 18 is a square ceramic insulating piece. The cooling end 18 is connected to the semiconductor of the electric refrigerator 19 through a metal conductor.

[0029] This product provides two cooling modes when in use. The first cooling mode is:

[0030] like Figure 1 and 2 As shown, the water inlet solenoid valve 9 and the water inlet pump 10 are turned on, and the irrigation water is introduced into the water supply tank 15 through the water inlet pipe 8. Then the water pump 13 is turned on to introduce the irrigation water into the cooling water tank 11 through the water pumping pipe 5. The electric refrigerator 19 is turned on, and the refrigeration end 18 quickly generates cold energy and reduces the temperature of the sealed refrigeration tank 17. The cold energy of the sealed refrigeration tank 17 is transmitted to the cooling water tank 11. The irrigation water with a higher temperature absorbs the cold energy in the cooling water tank 11 and its temperature is reduced. Then, it is transported to the cold water tank 16 through the return pipe 6 at the bottom of the cooling water tank 11. The water outlet solenoid valve 3 and the water outlet pump 4 are turned on, and the cooled water is output through the outlet pipe 2 to implement the aerated irrigation operation.

[0031] The second cooling method is:

[0032] like Figure 2 and 3As shown, the water inlet solenoid valve 9 and the water inlet pump 10 are opened, and the irrigation water is introduced into the water supply tank 15 through the water inlet pipe 8. Then the water pump 13 is opened to introduce the irrigation water into the cooling pipe 21 through the water pumping pipe 5. The electric refrigerator 19 is opened, and the cooling end 18 quickly generates cold energy. The higher temperature irrigation water absorbs the cold energy in the cooling pipe 21 and the temperature is lowered. Then, it is transported to the cold water tank 16 through the return pipe 6. The water outlet solenoid valve 3 and the water outlet pump 4 are opened, and the cooled water is output through the outlet pipe 2 to implement the aerated irrigation operation.

[0033] During operation, the electric refrigerator's heat sink 12 is equipped with heat dissipation fins, or the temperature is lowered through air or water cooling, effectively improving the cooling effect. Furthermore, a heat dissipation fan 7 is provided to extract heat from the water in the water supply tank 15, further enhancing the cooling effect during operation.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
