The first one-way valve 10 connected to the elastic air bag 7 communicates with the atmosphere through a first pipeline 12 and communicates with the said elastic air bag 7. The intake water end of the first one-way valve 10 connected to the elastic water bladder 8 is immersed in water, and the two second one-way valves 11 are communicated with the vertical pipe 13 through respective second pipes, one of which is the second pipe The upper end of the vertical pipe 13 is connected, and the other second pipe is connected to the side surface of the vertical pipe 13. The vertical pipe 13 is arranged under the planting bed 1. The diameter is 2-5mm and the bottom is provided with an opening.

The planting bed 1 is connected with the anchoring block 2, and the anchoring block 2 is fixed under the water to prevent the planting bed 1 from being washed away by the action of the water flow. The planting bed 1 includes a first floating block 3, a second floating block 4 and a hollow tube 5. The first floating block 3 and the second floating block 4 are provided with a planting groove 6, and aquatic plants are planted in the planting groove 6, The roots of aquatic plants can purify water. The openings at both ends of the hollow tube 5 are sealed to prevent the entry of water flow and reduce the sliding resistance of the gravity block 9 . The first floating block 3 and the second floating block 4 are connected at both ends of the hollow tube 5 , and when the water surface fluctuates, the lifting and lowering of the two floating blocks are not synchronized, thereby causing the hollow tube 5 to incline. Two ends of the hollow tube 5 are provided with elastic air bags 7 and elastic water bags 8, and the hollow tube 5 between the elastic air bags 7 and the elastic water bags 8 is provided with a sliding gravity block 9. When the hollow tube 5 is inclined, the gravity The block 9 slides down, thereby squeezing the elastic water bladder 8 or the elastic air bag 7 . The elastic air bag 7 and the elastic water bag 8 are respectively provided with a first one-way valve 10 and a second one-way valve 11. The first one-way valve 10 connected to the elastic air bag 7 communicates with the atmosphere through a first pipeline 12 and communicates with the said elastic air bag 7. The inlet water end of the first one-way valve 10 connected to the elastic water bladder 8 is immersed in water, and the first one-way valve 10 and the second one-way valve 11 ensure the flow stability of gas and liquid. When the elastic water bag 8 contracts, the liquid flows out from the second one-way valve 11, and when the elastic water bag 8 contracts, it flows into the first one-way valve 10 from the external liquid; During relaxation, the gas from the outside flows into the first one-way valve 10 . The vertical pipe 13 is arranged below the planting bed 1 , the two second one-way valves 11 communicate with the vertical pipe 13 through second pipes, and one of the second pipes communicates with the upper end of the vertical pipe 13 The other second pipe is connected to the side of the vertical pipe 13, because the gravity block 9 will alternately squeeze the elastic air bag 7 and the elastic water bag 8 when sliding back and forth, so the two second pipes are alternately directed to each other. The gas and liquid are transported in the vertical pipe 13, one of which is input from the top of the vertical pipe 13, and the other is input from the side of the vertical pipe 13. At the same time, since the diameter of the vertical pipe 13 is 2-5 mm, the vertical pipe 13 Alternating gas and water columns are formed inside, and when gas or liquid is input, both the gas column and the water column will be pushed down, and finally discharged from the opening at the bottom of the vertical pipe 13 . Due to the formation of alternating air columns and water columns in the vertical pipe 13, the water column will generate downward pressure to push the air column to move downward. In the case where the liquid level fluctuation is small, the elastic water bladder 8 and the elastic bladder 7 have insufficient thrust. It is also possible to inject gas into deeper water.

Specifically, rollers 14 are provided around the gravity block 9 , and the rollers 14 are in contact with the inner wall of the hollow tube 5 . The roller 14 reduces the friction between the gravity block 9 and the hollow tube 5 , which facilitates the sliding of the gravity block 9 .

In the process of reciprocating sliding of the gravity block 9, the elastic water bag 8 and the elastic air bag 7 alternately feed and discharge materials, so that the gas can be sent to the bottom of the water.

Specifically, the second pipe connecting the upper end of the vertical pipe 13 is connected to the second one-way valve 11 connected to the elastic air bag 7 , and the second pipe connecting the side surface of the vertical pipe 13 is connected to the elastic water bag 8 . The second one-way valve 11 is connected. The gas enters from the top of the vertical pipe 13, and a gas column is formed at the top of the vertical pipe 13. The liquid enters from the side of the vertical pipe 13. When entering, it is first adsorbed on the side wall to form water droplets. Hold the vertical pipe 13, and finally the water droplets extend to form a water column. The gas enters the vertical pipe 13 from the top, and the liquid enters the vertical pipe 13 from the side, which makes it easier to form alternating gas and water columns.

Specifically, the planting bed 1 further includes a third floating block 15 and a connecting rope 16 , the first floating block 3 and the second floating block 4 are provided with a surrounding plate 17 , and the surrounding plate 17 forms a cylindrical through-hole in the middle. A hole 18 , the third floating block 15 is set in the cylindrical through hole 18 , and the third floating block 15 is connected to the anchoring block 2 through a connecting rope 16 . The third floating block 15 floats in the cylindrical through hole 18 enclosed by the enclosure plate 17 , a part of the third floating block 15 is exposed to the water surface, a part of the enclosure plate 17 is submerged under water, and the enclosure plate 17 and the third floating block 15 are staggered. entity, so the planting bed 1 cannot float away from the third floating block 15. The third floating block 15 is connected to the anchoring block 2 through the connecting rope 16 , so that the position of the third floating block 15 is relatively fixed, thereby preventing the entire planting bed 1 from floating away under the action of water flow. When the first floating block 3 and the second floating block 4 fluctuate up and down, the connecting rope 16 will not be involved, and the amplitude of the fluctuation is increased, thereby facilitating the injection of gas into the water.

The length of the vertical pipe 13 can be expanded and contracted, so that the depth of the bottom opening of the vertical pipe 13 immersed in water can be adjusted. The vertical pipe 13 can be extended at a position where the water level is high, so that the gas can be discharged at a deeper position. When the depth of the vertical pipe 13 is relatively small, and the hydraulic pressure at the bottom of the vertical pipe 13 is relatively small, the three-way valve 23 is rotated to connect the first inner bellows 20 and the first outer bellows 21, and at the same time close the third The connection between the pipe 22 and the fourth pipe 24 has a large cross-sectional area of the elastic airbag 7, which increases the amount of gas discharged when the gravity block 9 slides. When the depth of the vertical pipe 13 is relatively large, the hydraulic pressure received at the bottom of the vertical pipe 13 is relatively large, and the three-way valve 23 is rotated to disconnect the first inner bellows 20 and the first outer bellows 21. At the same time, the second bellows 19 communicates with the fourth pipe 24, the cross-sectional area of the elastic airbag 7 is reduced, and the gas is more easily discharged when the gravity block 9 slides, thereby increasing the discharge depth of the gas. The cross-sectional area of the elastic bladder 7 can also be reduced when the liquid level fluctuation is small.
