DEVICE

TECHNICAL FIELD The invention belongs to the technical field of new energy development, and particularly relates to a semi-buried atmospheric self-condensing dew collecting device.

BACKGROUND Water is an indispensable resource for people's survival and development. However, with the development of human society, the reserve of fresh water on the earth is becoming less and less. How to obtain fresh water through new ways or methods has become a new subject that human beings must solve. At present, there are some devices that can obtain fresh water, such as seawater desalination devices, etc., but these devices are high in cost, low in desalination rate, complicated; moreover, these devices consume huge energy while producing fresh water, resulting in a large amount of greenhouse gas emissions. However, a large amount of water contained in the air can be captured by a specific method, which is not limited by time and space, and can show excellent applicability under many special conditions. Therefore, air water intake technology has great potential to solve the problem of freshwater scarcity. In addition, solar radiation is the main energy source on the earth, and solar energy is a clean energy source that will not cause pollution. To sum up, the invention designs an air water intake device based on the principle of refrigeration and condensation, it uses solar energy as energy source and uses semiconductor refrigeration sheet to realize water intake resources from condensed water in the air.

SUMMARY Aiming at the shortcomings of the prior art, the present invention provides a semiconductor water collector from air based on solar power supply, which can obtain liquid water from the air under the cooling effect of the semiconductor.

The specific technical scheme is as follows: A semi-buried atmospheric self-condensing dew collecting device comprises a photovoltaic power generation system, an collecting and draining water from air integrated U-shaped pipe and a semiconductor refrigeration module;

The collecting and draining water from air integrated U-shaped pipe comprises twdJ502163 longitudinal pipe parts and a horizontal pipe part; the longitudinal pipe at one end is an air inlet pipe, the nozzle of the air inlet pipe is connected to the air inlet duct, and the longitudinal pipe at the other end is an air outlet pipe; the horizontal pipe part is a ventilation-refrigeration pipe and is connected with a water outlet pipe at bottom end, The semiconductor refrigeration module is connected to the collecting and draining water from air integrated U-shaped pipe, and cools air in the collecting and draining water from air integrated U-shaped pipe; The semiconductor refrigeration module is powered by a photovoltaic power generation system.

Optionally, the semiconductor refrigeration module comprises a semiconductor refrigeration plate and a heat dissipation system; the semiconductor refrigeration plate is arranged at the upper end of the ventilation-refrigeration pipe, its cold end contacts the air in the pipe to condense the moisture in the air, and its hot end is connected with the heat dissipation system to make the semiconductor refrigeration plate work normally.

The ventilation-refrigeration pipe is located at the lower end of the semiconductor refrigeration plate, and flows down after condensation and water collection. The moisture in the air is condensed on the semiconductor refrigeration plate and the wall of the U-shaped pipe, and then drips into the water collecting tank to collect liquid water.

Further, the heat dissipation system comprises a radiating fin and a heat dissipation fan; the lower end of the radiating fin is connected with the semiconductor cooling plate, and the upper end is connected with the radiating fan.

Preferably, the outside of the radiating fan is provided with gauze to prevent foreign matters such as sand and stones from falling in.

Preferably, the air pumping system adopts a semi-buried design. Specifically, a part of the collecting and draining water from air integrated U-shaped pipe is placed underground, and the radiating fan is located above the ground. The nozzles of the air inlet pipe and the air outlet pipe are also located above the ground and communicate with the air.

The ventilation pipe adopts a semi-buried design, and its lower end is placed underground. By using the temperature difference between underground and above ground and the thermal insulation effect of soil, the electric energy consumption is reduced and the condensatiddJ502163 efficiency is effectively improved.

Further, the photovoltaic power generation system comprises a solar power generation panel, a storage battery and a solar controller; the solar panel is connected with a storage battery, the storage battery is connected with a semiconductor refrigeration module, and the storage battery is controlled by a solar controller to supply power to the semiconductor refrigeration module.

The solar power generation panel uses solar energy to generate electric energy in the daytime and stores it in the storage battery, which supplies energy for the semiconductor refrigeration panel in the semiconductor refrigeration module and the rotation of the cooling fan, so that the air water pumping device can work for 24 hours. The solar controller can control the current to adjust the cooling rate.

Further, the solar power generation panel is arranged at the top of the air inlet duct.

Further, the size of the inner cavity of the air inlet duct decreases from top to bottom.

The shape of the upper width and the lower width can accelerate the air flow.

Further, the peripheral wall of the air inlet duct is a louver type. The louver blades are horizontally arranged.

The side walls of louvers can guide the flow.

Further, the lower end of the ventilation-refrigeration pipe is an inclined opening, that is, the lower end is bucket-shaped, and the bottom opening of the bucket is connected with the water outlet pipe.

Further, the inner wall of the collecting and draining water from air integrated U-shaped pipe with hydrophobic materials, which is beneficial to the collection of condensed liquid water and its inflow into the soil.

The invention has the following beneficial effects: The invention breaks through the defect of high energy consumption and low water intake of the traditional air water intake device, innovatively utilizes photovoltaic power generation and simultaneously connects the storage battery to store electricity, so that the whole device can be more environment-friendly under the condition of 24-hour uninterrupted work. In addition, the semiconductor air water intake device does not need chemical refrigerant to condense hot air, which can be recycled by semiconductor refrigeration. At the same time, there is no chemical by-product, so it is truly green and environmentally friendly. The radiating fan and the radiatit&502163 fin can quickly cool the semiconductor refrigeration sheet and ensure the normal operation of the device. On the other hand, the semi-buried design of the semiconductor cooling air pumping device makes use of the temperature difference between the ground and the ground, which makes the hot and humid air in the device condense more quickly and save energy, compared with the traditional pumping device placed on the ground. At the same time, in order to further improve the air intake efficiency, the air intake duct is designed in a stepped streamlined manner and louvers are attached to increase the ventilation efficiency of the whole device. In addition, in order to improve the water intake efficiency, the air water collection system adopts an integrated U-shaped design, which can collect water and make the condensed water flow out of the outlet pipe in time by gravity. At the same time, the inner wall of the ventilation pipe is paved with hydrophobic materials, so that the condensed water can flow out of the pipe in time and quickly, thus greatly shortening the residence time of the condensed water in the device and improving the water pumping efficiency. To sum up, this semiconductor water collector from air uses the principle of refrigeration and condensation, uses solar energy as energy source, and uses semiconductor refrigeration sheet for refrigeration, so as to realize water intake resources from condensed water in the air, and at the same time, it is environmentally friendly.
