Description

Technical Field

[0001] This utility model relates to the field of irrigation, specifically to a desert water collection and irrigation device. Background Technology

[0002] Even in arid regions, the air still contains approximately 10% water vapor, representing a largely untapped water resource. While air-to-water technology is theoretically feasible, practical challenges include high energy consumption and dependence on external power sources. This is particularly true in relatively dry conditions, where the effectiveness of traditional condensation methods and moisture-absorbing materials often decreases significantly. Therefore, this technology is difficult to implement on a large scale in resource-scarce and energy-insufficient arid regions.

[0003] Current technological limitations: Currently, the main techniques for extracting moisture from the air include mechanical refrigeration condensation and the application of hygroscopic materials. Mechanical refrigeration works by lowering the air temperature to condense water vapor, but under low humidity conditions, the air contains less moisture, resulting in a significant reduction in condensation efficiency. Furthermore, this method is energy-intensive, making it unsuitable for widespread use in energy-scarce environments. While hygroscopic materials such as silica gel can effectively extract moisture from the air, efficiently releasing the adsorbed moisture from these materials remains a challenge, especially at night when temperatures are lower. Although the adsorption effect of the material may improve, the efficiency of moisture release often falls short of requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a desert water collection and irrigation device that efficiently obtains water resources.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A desert water collection and irrigation device includes a device body and a water collection container. The device body has an installation plate located above the water collection container. A control box is connected to the top surface of the installation plate, and a control module is installed inside the control box. A power supply module is installed on the installation plate, and a cooling module is installed on the bottom surface of the installation plate. The water collection container includes two oppositely arranged water collection pipes, each containing a water-absorbing material. A water storage tank is located between the two water collection pipes, containing a condenser. Each water collection pipe has an air inlet at its upper end, and an air intake fan is provided on the device body corresponding to each air inlet. The lower end of each water collection pipe is connected to the water storage tank. The water storage tank has at least one air outlet near the refrigeration module, and a water outlet is located at its lower end. The cold end of the refrigeration module is connected to the water-absorbing material via a cooling plate. The power supply module is used to provide operating power to the refrigeration module, the condenser and the control module.

[0006] Preferably, the power supply module includes a storage battery, and a solar power supply module and / or a wind power supply module electrically connected to the storage battery.

[0007] Preferably, each of the water collection pipes is integrally connected to the water storage device.

[0008] Preferably, a temperature sensor and a humidity sensor are installed inside the water collection pipe, and the temperature sensor and the humidity sensor are respectively communicatively connected to the control module.

[0009] Preferably, a heat dissipation module is provided between the power supply module and the cooling module in the device body.

[0010] Preferably, the water collection pipe is a transparent water collection pipe.

[0011] Preferably, the device body is connected to two focusing plates, and the two focusing plates are respectively arranged around the two water collection pipes in a one-to-one correspondence.

[0014] Preferably, the condenser is fixed to the inner top surface of the water storage tank, and the condenser is connected to multiple metal water collection columns, each of which is disposed inside the water storage tank.

[0015] By adopting the aforementioned design scheme, the beneficial effects of the present invention are as follows: The desert water collection and irrigation device of this application can turn on the air intake fan at night or during low temperature periods, so that the water-absorbing material in the water collection pipe can absorb moisture from the air. During the day or during high temperature periods, the air intake fan at the air inlet is turned off and the cooling module is started. The cold end of the cooling module is connected to the water-absorbing material through a metal connection, so that the cooling module can reduce the temperature of the water-absorbing material. When the temperature of the water-absorbing material drops to a certain value, the water in the water-absorbing material begins to desorb and form water vapor. The water vapor enters the water storage tank and exchanges heat with the condenser, so that the water vapor condenses into liquid water. Attached Figure Description

[0019] In this embodiment, the orientation of the water collection and irrigation device on the horizontal plane is used as the reference direction for the vertical orientation.

[0020] Example 1 like Figures 1-2 As shown, a desert water collection and irrigation device includes a device body and a water collection container. The device body has a mounting plate 01, which is located above the water collection container.

[0021] In this embodiment, the control box is made of a corrosion-resistant and weather-resistant material to protect the internal components from the influence of the external environment. ABS or aluminum can be used to make the control box.

[0022] In this embodiment, the power supply module includes a storage battery, and a solar power supply module and / or a wind power supply module electrically connected to the storage battery.

The solar panel 13 is fixedly connected to the mounting plate 01. The turbine blade 12 and the solar panel 13 are electrically connected to the generator 11, and the generator 11 is electrically connected to the storage battery. By setting up a dual power supply system of solar and wind power, the desert water collection and irrigation device can achieve environmentally friendly water intake, ensure the stable operation of the device under different climatic conditions, and also set up a storage battery as an energy storage device to provide the device with the required power when there is a lack of sunlight and wind.

[0023] The water collection container includes two oppositely arranged water collection pipes 21, each containing absorbent material. A water storage tank 31 is located between the two water collection pipes 21, containing a condenser. Each water collection pipe 21 has an air inlet at its upper end. An intake fan b is provided on the main body of the device corresponding to each air inlet. The intake fan b is a conventional intake fan. The lower end of each water collection pipe 21 is connected to the water storage tank 31. The water storage tank 31 has at least one air outlet near the refrigeration module a, and a water outlet is located at its lower end. The cold end of the refrigeration module a is connected to the absorbent material via a heat-conducting plate. In this embodiment, the refrigeration module a is a thermoelectric refrigeration module, and the heat-conducting plate is a conventional metal thermal bridge. The metal thermal bridge connects the cold end of the refrigeration module a to the absorbent material, ensuring efficient heat transfer.

[0024] In this embodiment, the water storage device 31 is provided with two symmetrically distributed air outlets, and each air outlet is provided with multiple air outlet holes 311.

[0025] The power supply module is used to provide operating power to the refrigeration module, condenser, and control module; in this embodiment, the power supply module, refrigeration module, condenser, and control module are all conventional electronic components.

[0026] In a preferred embodiment, a temperature sensor and a humidity sensor are installed inside the water collection pipe 21. The temperature sensor and the humidity sensor are respectively connected to the control module and are electrically connected to the power supply module. By installing the temperature sensor and the humidity sensor inside the water collection pipe 21, the control module can obtain the temperature and humidity conditions inside the water collection pipe 21.

[0027] In a preferred embodiment, the device body is provided with a heat dissipation module c between the power supply module and the cooling module a. In this embodiment, the heat dissipation module c is a conventional cooling fan.

[0028] In this embodiment, the condenser is a finned condenser, which adopts a finned structure design to increase the heat dissipation area and improve the condensation effect. At the same time, a fan is set to enhance air convection and promote heat dissipation.

[0029] In a preferred embodiment, the water collection pipe 21 is a transparent water collection pipe, and the water-absorbing material is NOV water-absorbing material; two light-concentrating plates 22 are connected to the main body of the device, and the two light-concentrating plates 22 are respectively arranged around the two water collection pipes 21 in a one-to-one correspondence. The light-concentrating plates 22 are arc-shaped or semi-circular so that the light-concentrating plates 22 can concentrate sunlight on the water collection pipes 21 to increase the temperature of the water collection pipes 21, which is conducive to the desorption of moisture in the water-absorbing material.

[0030] In a preferred embodiment, the condenser is fixed on the inner top surface of the water reservoir 31, and the condenser is connected to multiple metal water collection columns, each of which is located inside the water reservoir 31.

[0031] Example 2 like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that: the desert water collection and irrigation device does not have a wind power supply module; the control box 41 is fixedly or integrally connected to the mounting plate 01; the control module 42 and the battery are installed inside the control box 41; the solar panel 13 is fixedly connected to the top of the control box 41; the water collection container includes a water collection pipe 21 and a water storage tank 31; the water collection pipe 21 is integrally or fixedly connected to a condenser pipe 211; the water storage tank 31 has two connection holes; the lower end of the condenser pipe 211 is integrally connected to two water outlet pipes; the two water outlet pipes are respectively inserted into the two connection holes; the condenser pipe 211 is connected to the water storage tank 31 through the water outlet pipes, so that the liquid water condensed by the condenser pipe 211 flows into the water storage tank 31; the upper end of the condenser pipe 211 is connected to a condenser, a cooling module a, and a heat dissipation module c in sequence from bottom to top.

[0032] As a preferred embodiment, a water level sensor is installed on the inner top surface of the water storage tank 31, and an automatic drainage device is connected to the bottom of the water storage tank 31. The water level sensor and the automatic drainage device are respectively connected to the control module 42 to ensure water quality safety and prevent the water storage tank from overflowing. In this embodiment, both the water level sensor and the automatic drainage device are conventional devices.

[0033] like Figure 4As shown in the relative humidity and dew point temperature table published by the China Meteorological Administration, the principle of obtaining water from the air requires lowering the ambient air temperature to the dew point temperature, causing the water vapor to drop to zero. Desert environments are often hot and dry. Taking the Sahara Desert as an example, daytime temperatures can rise above 50 degrees Celsius, sometimes even higher; at night, the temperature drops rapidly, sometimes to below -10 degrees Celsius. Now, taking a daytime temperature of 49 degrees Celsius (30% humidity) as an example, to obtain water, according to the relative humidity and dew point temperature table published by the China Meteorological Administration, the air temperature must be lowered to 25 degrees Celsius. Typically, semiconductor cooling can theoretically achieve a temperature difference of up to 60 degrees Celsius. However, due to environmental factors, current, voltage, and thermal conductivity, the actual measured temperature difference indoors is around 46 degrees Celsius. In an outdoor environment of 49 degrees Celsius, the hot end temperature of the semiconductor cooling chip reaches 72 degrees Celsius, while the cold end temperature is only measured at around 26 degrees Celsius, making it impossible to reach the dew point temperature of 25 degrees Celsius. Therefore, obtaining water in the desert becomes very difficult. To solve this problem, we use a moisture-absorbing material as a transfer medium. It absorbs moisture from the air at night, dehydrates during the day, and enters a cooling cavity to increase the humidity in the cavity, thereby collecting water in the desert for irrigation of plants.

[0034] In this embodiment, the coordination, activation, or deactivation of each module can be set by the control module according to the actual usage environment. For example, when the temperature is higher than 40°C, the intake fan can be turned off.

[0035] In summary, the desert water collection and irrigation device of this application can utilize natural wind at night or during low-temperature periods to allow the water-absorbing material in the water collection pipe 21 to absorb moisture from the air. During the day or during high-temperature periods, the intake fan at the air inlet is closed, and the cooling module a is activated. The cold end of the cooling module a is connected to the water-absorbing material through a metal connection, so that the cooling module a can reduce the temperature of the water-absorbing material. When the temperature of the water-absorbing material drops to a certain value, the water in the water-absorbing material begins to desorb and form water vapor. The water vapor enters the water storage tank 31 and exchanges heat with the condenser, causing the water vapor to condense into liquid water.

[0036] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
