The electric fan 1 is connected to the air intake shed column 12, and the upper end of the connection is provided with a first quicksand port 103, and the first quicksand port 103 is ring-shaped. When air enters the electric fan 1, under the centrifugal action of the electric fan 1, large particles of sand and dust will flow out of the first quicksand port 103 to prevent clogging of the pipeline, and small particles of dust will enter the intake air through the first sand filter 101 The shed pillar 12 finally falls into the sand leakage pipe 10.

When the gas enters the intake shed column 12, it flows through the thermoelectric power generation sheet 4 and the refrigeration sheet 6 (made of semiconductor material). The thermoelectric power generation sheet 4 utilizes the temperature difference between the outside of the shed column and the inside of the shed column, and the heat from the hot end of the refrigerating fin 6 is integrated into the intake shed column 12 to generate power, and the power generated is input into the storage battery 13. The refrigerating fin 6 is powered by the storage battery 13 for refrigeration, and the condensed water produced by the refrigeration flows into the water storage tank 14;

In this embodiment, the thermoelectric power generation sheet 4 is placed on the outer surface of the intake shed column outside the shed, the cooling sheet 6 is placed on the inner side surface of the intake shed column 12, and the cooling sheet 6 The hot end faces the inside of the intake shed column 12, and the cold end faces the outside of the intake shed column 12 (inside the shed).

The gravity is less than the pressure of the spring on the valve cover, and the valve is closed, which plays the role of timing, quantitative watering, watering a certain distance, and watering in place.

The air inlet shed column 12 is made of existing thermal insulation materials; the gas is input into the ground through the electric fan 1 and the air inlet shed column 12 through multiple thin connecting pipes 9 with fast heat conduction, due to the effect of temperature difference ( The temperature difference between the outside of the shed column and the underground) condenses the water in the gas, and the condensed water flows into the water storage tank 14. The condensed gas is collected into a pipe and passed through the gas exhaust shed column 5, and the unpowered hood 3 drives the gas to be discharged.

A plurality of thin connecting pipes 9 with fast heat conduction are connected to the lower end of the air inlet shed column 12, and the connecting pipe 9 is made of high thermal conductivity material, such as copper, aluminum, etc.; the other end of the thin connecting pipe 9 with fast heat conduction is connected to the exhaust shed Column 5, the top end of the exhaust shed column 5 is connected with an unpowered hood 3, the connection between the unpowered hood 3 and the gas discharge shed column 5 is provided with a second quicksand port 33, and the unpowered hood 3 is brought in when it rotates The large particle size dust (due to centrifugal effect) is discharged through the second quicksand port 33 (the second quicksand port 33 is at the junction of the second sand filter and the unpowered wind cap), and the small particle size dust passes through the second The sand filter 32 enters the exhaust shed column 5 and finally falls into the sand leakage pipe 10. When the gas flows through the exhaust shed column 5, the thermoelectric power generation fins that flow through, and the refrigeration fins also play the role of generating power and condensing to obtain condensed water. The above-mentioned structure is a unit. The above-mentioned units are provided in the desert automatic water fetching seedling shed.

The lower ends of the intake shed column 12 and the exhaust shed column 5 are vertically connected with a sand-dust sand leakage pipe 10 for the sedimentation of sand and dust and prevent the pipeline from being blocked; The depth of 9 is about one meter, and it is intended that the small particle size dust passing through the sand filter will accumulate here and will not enter the heat transfer tube 9.

The lower end of the shed column is connected with a ground anchor 11, as shown in Figure 5; the operation method of the ground anchor 11: when in use, the extension rod 113 and the movable shaft 114 are sleeved in the moving pipe 112, and the moving pipe 112 is rotated into the ground; After entering the ground, the moving tube 112 rotates upwards, exposing the extension rod 113 and the movable shaft 114, and pulls the pulling rod 111 so that the extension rod 113 rotates and opens through the rotating shaft 114 to achieve a fixed effect in the underground. When the ground anchor is to be pulled out, the operation is reversed. The ground anchor is connected to the solar photovoltaic power generation board on the top of the shed with a wire to protect against lightning and lightning. The ground anchor is made of metal materials.
