Abstract
Description
Technical Field
[0001] This invention belongs to the field of solar power generation and refrigeration, and relates to a novel technology for cooling soil and storing water for planting using solar power generation and refrigeration. Specifically, it is a planting technology that uses solar power generation and refrigeration to cool soil and store water. Background Technology
[0002] Deserts now cover 20% of the world's land area, and another 43% of the land is facing the threat of desertification.
[0003] The most fundamental solution to Earth's water scarcity lies in reducing surface evaporation and addressing soil moisture content through underground freezing. Once the surface soil moisture content is maintained at a level sufficient to meet the water needs of surface plants, a significant increase in surface vegetation cover will fundamentally alter the ecological conditions of the Earth's surface. A technology using solar energy for cooling and water storage in underground soil (202521514657X) proposes a solution for agricultural planting using solar energy for cooling and underground water storage in arid regions, but it still has the following drawbacks or shortcomings:
[0004] 1. Solar panels often have a shading effect, reducing evaporation in summer. On the other hand, in the heart of desert regions, where wind and sand are very strong and shifting sands are severe, the proper layout of solar panels can block desert storms, reduce and mitigate the impact of wind and sand, and lower the cost of agricultural development in desert regions.
[0005] 2. Extensive underground cooling leads to excessively low underground temperatures, which damages plant roots and further affects plant growth. It is necessary to address the relationship between plant growth and low-temperature soil.
[0006] 3. Since solar cooling has a high energy cost, in order to reduce the energy cost, it is necessary to further reduce the cooling loss from the cooling layer to the ground.
[0007] 4. Since underground refrigeration is intended to provide water to plant roots, only melted water can be absorbed by plant roots. Therefore, it is necessary to appropriately control the refrigeration power, prevent the volume of frozen soil from becoming too large, and improve the water storage capacity of melted water to reduce or avoid the seepage and loss of melted water into the deep underground.
[0008] Therefore, we can reduce desert wind speed and mitigate the adverse effects of wind by rationally arranging solar photovoltaic panels for shading and power generation, thereby reducing initial development costs. By rationally differentiating and arranging planting areas and frozen water storage areas, we can utilize solar energy to significantly cool and freeze the soil while ensuring the plants' water needs are met, preventing plant roots from being frozen and unable to effectively take root and absorb water.
[0009] Further optimize the underlying insulation and seepage prevention structure to minimize the loss of meltwater and drip irrigation water, as well as the underground loss of cold energy. Summary of the Invention
[0010] This invention is a technical solution proposed to solve the above-mentioned problems, and it is based on the following principles:
[0011] 1. Optimization of photovoltaic panel layout
[0012] Existing photovoltaic (PV) matrix designs are too low in height and too high in density. For arid or desert regions, it is necessary to simultaneously address the issues of PV panel shading and optimizing agricultural conditions. This should facilitate large machinery to carry out agricultural operations under the PV panels, while ensuring the PV panels' resistance to wind and sand in desert regions.
[0013] 2. The structure of the thermal insulation and seepage prevention layer needs to be optimized to improve its thermal insulation and seepage prevention capabilities and extend the service life of the entire system.
[0014] 3. Properly distinguish between the frozen water storage area and the planting area to provide adequate space for the plant roots to extend downwards.
[0015] To achieve comprehensive underground cooling and water storage capabilities, as well as rational zoning of drip-irrigated plants, the technical solution adopted in this invention is as follows:
[0016] This invention is a planting technology that uses solar power to generate electricity for cooling and water storage in the soil. It includes a seepage-proof water storage tank 1, a seepage-proof and heat-insulating water storage tank 2, a cooling pipe 3, a cooling pipe sleeve 4, a drip irrigation pipe 5, a breathable layer 6, an organic fertilizer treatment plant zone 7, an organic matter treatment freezing zone 8, a surface organic heat insulation layer 9, a planting tree 10, an excavation interface 11, a water-absorbing layer 12, a chiller 13, a photovoltaic panel 14, cash crops 15, an organic anti-corrosion sealed bag 16, organic matter 17, a plot of cultivated land 18, and a cooling main pipe 19.
[0017] The seepage-proof water storage tank 1 is characterized by being concave and installed below the organic fertilizer treatment plant section 7. The seepage-proof water storage tank 1 is made of seepage-proof and heat-insulating material and is arranged vertically in a wavy shape when installed underground.
[0018] The seepage-proof and heat-insulating water storage tank 2 is characterized by its concave shape and is installed below the organic matter treatment freezing zone 8. The seepage-proof and heat-insulating water storage tank 2 is made of seepage-proof and heat-insulating material. Its features include an organic anti-corrosion sealed bag 16 on its outer side, organic matter 17 inside which is vacuum sealed, and a wavy vertical arrangement when installed underground.
[0019] The refrigeration pipe 3 is characterized in that the refrigeration pipe 3 is connected to the main refrigeration pipe 19, and the end of the external refrigeration pipe sleeve 4 is sealed with the refrigeration pipe 3 when the refrigeration pipe 3 enters the ground.
[0020] The drip irrigation pipe 5 is characterized in that it is arranged directly above the organic fertilizer treatment plant zone 7;
[0021] The permeable layer 6 is characterized in that it is laid above the refrigeration pipe sleeve 4, and part of the permeable layer 6 extends upward through the machine insulation layer 9 to near the ground. The permeable layer 6 is composed of anti-corrosion organic materials that have been treated for corrosion prevention, or is composed of corn, bamboo, or other wood or grass covered with plastic and vacuum-sealed and stacked, ensuring large pores and ventilation on the basis of corrosion prevention.
[0022] The organic fertilizer treatment plant zone 7 is characterized by its area being interspersed with the organic matter treatment freezing zone 8, with an organic surface insulation layer 9 above it and a seepage-proof water storage tank 1 below it. Agricultural planting trees 10 and cash crops 15 are distributed above the organic fertilizer treatment plant zone 7.
[0023] The organic matter treatment freezing zone 8 is characterized in that its area is interspersed with the organic fertilizer treatment plant zone 7. The upper part of its width is the surface organic heat insulation layer 9, the lower part of the air permeable layer 6 extends upward to near the ground, below the air permeable layer 6 is the refrigeration pipe sleeve 4 with the refrigeration pipe 3 inside, below that is the water absorption layer 12, and below the water absorption layer 12 is the seepage-proof heat insulation water storage tank 2.
[0024] The segmented farmland 18 is characterized in that it is equipped with photovoltaic panels 14 around its perimeter.
[0025] This invention relates to a planting technology that utilizes solar power to generate electricity for cooling and water storage in the soil. It includes a seepage-proof water storage tank 1, a seepage-proof and heat-insulating water storage tank 2, a cooling pipe 3, a cooling pipe sleeve 4, a drip irrigation pipe 5, a breathable layer 6, an organic fertilizer treatment plant zone 7, an organic matter treatment freezing zone 8, a surface organic insulation layer 9, planted trees 10, an excavation interface 11, a water-absorbing layer 12, a chiller 13, photovoltaic panels 14, cash crops 15, organic anti-corrosion sealed bags 16, organic matter 17, plotted cultivated land 18, and a main cooling pipe 19.
[0026] Working principle:
[0027] The surface organic insulation layer 9 contains a large amount of organic matter, and its thermal conductivity is no more than 0.12 W / (mK). It avoids the loss of cold energy and the large amount of water vapor evaporation through insulation.
[0028] When the refrigeration pipe 3 enters the underground, the end of the external refrigeration pipe sleeve 4 is sealed to prevent a large amount of water vapor from freezing the refrigeration pipe 3, which would affect the heat dissipation power and service life of the refrigeration pipe 3.
[0029] The drip irrigation pipe 5 is installed in the organic fertilizer treatment plant zone 7, which is a high-temperature zone in the ground and is located near the ground surface and near the roots of trees or plants, which improves the survival rate of plants and avoids being frozen by the freezing layer around the cooling pipe 3, thus affecting its use.
[0030] The organic fertilizer treatment plant zone 7 is characterized by its alternating arrangement with the organic matter treatment freezing zone 8. Above it is a surface organic insulation layer 9, and below it is a seepage-proof water storage tank 1. Since the temperature of the organic fertilizer treatment plant zone 7 is relatively high, it is generally not located within the freezing zone of the refrigeration pipe 3. Therefore, the planted trees 10 and cash crops 15 for agricultural planting are distributed above the organic fertilizer treatment plant zone 7 to avoid the plant roots being damaged by the low temperature of the freezing zone, which would affect survival and yield.
[0031] The aforementioned seepage-proof water storage tank 1 is characterized by its concave shape and is installed below the organic fertilizer treatment plant zone 7. The seepage-proof water storage tank 1 is made of seepage-proof and heat-insulating material. When installed underground, it is arranged vertically in a wavy shape. The seepage-proof and heat-insulating material is used to ensure that water is kept near the plant roots to the maximum extent. The wavy vertical arrangement prevents water from seeping into the seepage-proof water storage tank 1 and flowing away in one direction, thus affecting the uniformity of water distribution.
[0032] The seepage-proof and heat-insulating water storage tank 2 is characterized by its concave shape and is installed below the organic matter treatment freezing zone 8. The seepage-proof and heat-insulating water storage tank 2 is made of seepage-proof and heat-insulating material. Its features include an organic anti-corrosion sealed bag 16 on the outside and organic matter 17 inside, which is vacuum sealed to maximize the service life of the seepage-proof and heat-insulating water storage tank 2. When installed underground, it is arranged vertically in a wave-like shape. The vertical wave-like arrangement prevents water from seeping into the seepage-proof and heat-insulating water storage tank 2 and flowing away in one direction, thus affecting the uniformity of water distribution.
[0033] The plotted farmland 18 is characterized by having photovoltaic panels 14 arranged around its perimeter, which reduce and prevent wind disasters through the wind-blocking effect of the photovoltaic panels.
[0034] The permeable layer 6 is characterized in that it is arranged above the refrigeration pipe sleeve 4. The permeable layer 6 is composed of anti-corrosion organic materials, or is composed of corn, bamboo, or other wood or grass covered with sealed plastic and vacuum-sealed stacked. On the basis of anti-corrosion, it ensures large pores and ventilation. Because the lifespan of organic materials in a water environment is relatively short, once the organic materials rot and turn into mud, the cooling effect of the refrigeration pipe 3 will be reduced. By sealing the plastic and vacuuming, the service life is improved. The permeable layer 6 provides condensation moisture to the frozen soil layer near the refrigeration pipe sleeve 4 by communicating with the surface air.
[0035] The organic matter treatment freezing zone 8 is characterized by its alternating arrangement with the organic fertilizer treatment plant zone 7. Above it is a surface organic heat insulation layer 9, and below it is a breathable layer 6 extending upwards to the ground. Below the breathable layer 6 is a refrigeration pipe sleeve 4 with a built-in refrigeration pipe 3. Below that is a water absorption layer 12, and below the water absorption layer 12 is a seepage-proof and heat-insulating water storage tank 2. Since the organic matter treatment freezing zone 8 is in a frozen state all year round, organic fertilizer is difficult to play an effective role. Therefore, organic matter is used to improve the water content of the sand body. Attached Figure Description

Detailed Implementation
[0040] The following is in conjunction with the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 The structure of the present invention and its beneficial effects are further explained below.
[0041] Example 1
[0042] A planting technology that uses solar power to generate cooling and water storage in the soil, such as... Figure 1 , Figure 2 , Figure 3 1. Seepage-proof water storage tank; 2. Seepage-proof and heat-insulating water storage tank; 3. Refrigeration pipe; 4. Refrigeration pipe sleeve; 5. Drip irrigation pipe; 6. Breathable layer; 7. Organic fertilizer treatment plant zone; 8.

[0043] Its working principle: The photovoltaic panel 14 generates electricity to supply power to the chiller 13. The chiller 13 transfers the cold energy to the cooling main pipe 19. The cooling main pipe 19 then transfers the cold energy to the cooling pipe 3. When the cooling pipe 3 enters the ground, it is connected to the external cooling pipe sleeve 4. The end of the sleeve is sealed to the cooling pipe 3 to prevent water vapor from freezing into the cooling pipe 3, which would affect the heat dissipation power and service life of the cooling pipe 3.
[0044] The cold energy continuously generated by the refrigeration pipe 3 is transferred to the ventilated layer 6 through the refrigeration pipe sleeve 4. The ventilated layer 6 is characterized by being arranged above the refrigeration pipe sleeve 4. The ventilated layer 6 is composed of artificial anti-corrosion organic materials, or is composed of corn, bamboo, or other wood or grass covered with a plastic outer shell and vacuum-sealed. It ensures large pores and ventilation on the basis of anti-corrosion. Because organic materials have a relatively short lifespan in aquatic environments, once the organic materials rot and turn into mud, the cooling effect of the refrigeration pipe 3 will decrease. By sealing the plastic with a vacuum, the service life is improved.
[0045] The permeable layer 6 further transfers heat to the organic matter treatment freezing zone 8 and the organic fertilizer treatment plant zone 7 above it. The organic matter treatment freezing zone 8 further transfers cold energy to the surface organic insulation layer 9 above it. The cold energy combines with water vapor in the air entering the surface organic insulation layer 9 and condenses into flowing water, which seeps down to the frozen surface and further becomes ice.
[0046] The organic fertilizer treatment plant zone 7 further transfers the cold energy to the surface organic insulation layer 9 above it. The cold energy combines with the water vapor in the air entering the surface organic insulation layer 9 and condenses into flowing water, which seeps down to the frozen surface and further becomes ice.
[0047] The organic matter treatment freezing zone 8 is characterized by its alternating arrangement with the organic fertilizer treatment plant zone 7. Above it is a surface organic insulation layer 9, and below it is a breathable layer 6 extending upwards to near the ground. Below the breathable layer 6 is a refrigeration pipe sleeve 4 with a built-in refrigeration pipe 3. Below that is a water-absorbing layer 12, and below the water-absorbing layer 12 is a seepage-proof and heat-insulating water storage tank 2. Since the organic matter treatment freezing zone 8 is frozen all year round, organic fertilizer is difficult to play an effective role. Therefore, organic matter is used to improve the water content of the sand body. When the seepage-proof and heat-insulating water storage tank 2 is installed underground, it is arranged vertically in a wave shape. The vertical wave shape prevents water from seeping into the seepage-proof and heat-insulating water storage tank 2 and flowing away in one direction, affecting the uniformity of water.
[0048] The organic fertilizer treatment plant zone 7 is characterized by its alternating arrangement with the organic matter treatment freezing zone 8. Above it is a surface organic insulation layer 9, and below it is a seepage-proof water storage tank 1. Since the temperature of the organic fertilizer treatment plant zone 7 is relatively high, it is generally not located within the freezing zone of the refrigeration pipe 3. Therefore, the planted trees 10 and cash crops 15 are distributed above the organic fertilizer treatment plant zone 7 to avoid damage to the plant roots by the low temperature of the freezing zone, which would affect their survival and yield. The organic fertilizer treatment plant zone 7 receives cold energy from the organic matter treatment freezing zone 8 laterally, and its temperature continuously decreases, thereby reducing the temperature of the underground soil and reducing the rate of water evaporation. Condensate and water from the drip irrigation pipe 5 are stored in the seepage-proof water storage tank 1 to prevent seepage and loss.
