In the concrete implementation process, when the evaporation rate of vegetation water and soil surface water is too high, the water on the soil surface is rapidly reduced, but the amount of salt solute consisting of various elements rich in the soil surface is not reduced, so that the concentration of the salt solute is increased, and the salt solute is transmitted to a high-concentration position to a low-concentration position due to a certain diffusion effect and the salt solute is transmitted to the low-concentration position, so that the concentration difference is gradually reduced, and therefore, the salt solute near the soil surface gradually permeates downwards along with the increase of the concentration.
Therefore, the salt solute can permeate to the infiltration collecting port 1 during downward osmosis, the infiltration collecting port 1 collects the infiltration salt solute, the salt solute is gradually accumulated in the infiltration collecting port 1, and the salt solute can also gradually permeate to the first relay cavity 3 from the first infiltration pipeline 2 during accumulation; in the first relay chamber 3, the saline solution permeates downwards in any mode, when the kidney passes through the bottom of the first relay chamber 3, the saline solution can be gradually accumulated and can permeate downwards from the second infiltration pipeline 4 to the second relay chamber 5 while being accumulated, and during the infiltration, the saline solution can be filtered by the infiltration membrane 8, so that the saline solution cannot permeate downwards from the second infiltration pipeline 4 to the second relay chamber 5 without restriction.
When the second infiltration pipeline 4 infiltrates into the second relay cavity 5 to the joint of the second infiltration pipeline 4 and the second relay cavity 5, the salt solute can contact the rice-shaped beam frame 10, on the rice-shaped beam frame 10, the salt solute can infiltrate downwards along the rice-shaped beam frame 10 and finally is guided to the cavity wall of the second relay cavity 5 by the guide strips 11 and infiltrates downwards along the cavity wall, when the salt solute infiltrates into the bottom of the second relay cavity 5, part of the salt solute can enter the concave groove 9, part of the salt solute is retained in the concave groove 9, and the rest of the salt solute continues to infiltrate through the permeable membrane 8 and then infiltrates into the third relay cavity 7 by the third infiltration pipeline 6.
When the third infiltration pipeline 6 infiltrates into the third relay cavity 7 to the joint of the third infiltration pipeline 6 and the third relay cavity 7, the salt solute can contact the rice-shaped beam frame 10, on the rice-shaped beam frame 10, the salt solute can infiltrate downwards along the rice-shaped beam frame 10, finally is guided to the cavity wall of the third relay cavity 7 by the guide strips 11 and infiltrates downwards along the cavity wall, when the salt solute infiltrates into the bottom of the third relay cavity 7, part of the salt solute can enter the concave groove 9, part of the salt solute is retained in the concave groove 9, and the rest of the salt solute continues to infiltrate from the third infiltration pipeline 6 to the branch pipeline through the osmosis membrane 8.
Since the aperture of the first infiltration pipe 2 is larger than that of the second infiltration pipe 4, the aperture of the second infiltration pipe 4 is larger than that of the third infiltration pipe 6, and it is worth mentioning that the flow rate of the first infiltration pipe 2 is higher than the sum of the flow rates of the second infiltration pipes 4, and the sum of the flow rates of the second infiltration pipes 4 is higher than that of the third infiltration pipe 6, the concentration of the salt solute in the first relay chamber 3 is larger than that of the second relay chamber 5, and the sum of the concentration of the salt solute in the second relay chamber 5 is larger than that of the third relay chamber 7, so that the chemical energy in the first relay chamber 3 is larger than that of the second relay chamber 5, and the sum of the chemical energy in the second relay chamber 5 is larger than that of the third relay chamber 7, and the potential energy converted into water is that the water potential in the first relay chamber 3 is smaller than that of the second relay chamber 5, and the water potential of the second relay chamber 5 is smaller than that of the third relay chamber 7, so that the water tends to permeate from the third relay chamber 7 to the second relay chamber 5 and from the second relay chamber 5 to the first relay chamber 3.
The inner cavity 19 is internally provided with a permanent magnet, the different poles of the permanent magnet are opposite, the transition lead coil is connected with the electromagnetic valve and is provided with a coil lead, one end of the coil lead is a coil and is arranged in the inner cavity 19 at one side of the secondary pipeline 14 provided with the permanent magnet, and the other end of the coil lead is connected with the transition lead coil.
When water flows into the secondary pipeline 14, the water flows through the propeller 17, the propeller 17 is driven by the water flow to rotate, the propeller 17 rotates to drive the rotating shaft to rotate, the rotating shaft rotates to drive the coil conducting wire arranged on the rotating shaft to rotate, the coil of the coil conducting wire rotates in the inner cavity 19 on one side of the secondary pipeline 14, the permanent magnets are arranged in the inner cavity 19, the permanent magnets attract each other due to the fact that the opposite poles of the permanent magnets are opposite, a magnetic field exists, the part, parallel to the rotating shaft, of the coil conducting wire is perpendicular to the magnetic induction lines of the magnetic field of the permanent magnets, therefore, when the rotating shaft drives the coil of the coil conducting wire to rotate, the coil of the coil conducting wire does the motion of cutting the magnetic induction lines, according to the Faraday's law of magnetic induction, when the conducting wire in a closed loop does the motion of cutting the magnetic induction lines, in the coil of the coil wire, the part of the wire parallel to the rotating shaft performs the cutting magnetic induction wire movement, so a certain current can be generated in the part of the wire, and the current can have certain influence on the electromagnetic valve when flowing through the electromagnetic valve. According to Faraday's law of electromagnetic induction, the stronger the motion of cutting magnetic induction line, the larger the current that is produced, therefore, when the velocity of water flow that flows into secondary pipe 14 through pellicle 16 is very fast, when the water yield is very much, screw 17 pivoted speed also can increase, and then make the rotation axis drive the rotatory speed of coil wire become fast, thereby make the speed that coil wire cutting magnetic induction line moved become fast, thereby make the electric current increase, when the electric current increases, then represented the dynamics of irrigating and grow gradually, consequently need the bore increase of outlet, and represent the bore adjustment increase of solenoid valve with the outlet when the electric current increases, with corresponding to each other in principle.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
