When the tensiometer works, at this time, the water sources inside the jacking pipe 3, the inner port 4 and the ceramic head body 2 permeate into soil through micropores on the outer surface of the ceramic head body 2, at this time, along with disappearance of the water sources inside the jacking pipe 3, the inner port 4 and the ceramic head body 2, at this time, negative pressure is generated in a space above the water sources of the ceramic head body 2, the jacking pipe 3 and the inner port 4, and the manometer body 26 detects the negative pressure, so that a negative pressure value is displayed, an operator can check the negative pressure value displayed by the manometer body 26 regularly, so that the humidity of the soil is obtained according to the negative pressure value, and the growing environment information of the wild plants is judged.
When an operator finishes information acquisition of the wild plant growth environment, mud water in the soil hole is disappeared, at this time, soil in the soil hole and the soil in the inner wall of the soil hole can be in contact with the outer surface of the negative pressure meter extension pipe body 1, at this time, the operator can open the first electromagnetic valve 16 to close the second electromagnetic valve 19, and rotate the threaded sleeve 24 downwards to push the track block 23 and the connecting plate 22 to move downwards, and meanwhile, the mounting plate 29 can push the moving block 14 to move downwards in the cavity 13, so that the moving block 14 can push gas below the moving block to enter the top of the inner cavity of the annular cavity 8 through the first electromagnetic valve 16 and the air inlet channel 15, and under the action of air pressure, the moving block 9 can drive the moving block 11 to move downwards through the connecting rod 10, and the flexible spring 12 can be in a compressed state, and the moving block 11 moves downwards in the outer cavity 5, at this time, under the action of water pressure, the rubber film 6 can expand, at this time, the through holes in the outer side of the outer cavity 5 can push the moving block 14 to enter the top of the inner cavity through the rubber film 6, and the through holes 7, the air inlet 7 can be evenly distributed on the inner surface of the inner cavity and the inner cavity of the inner cavity, and the inner cavity of the inner cavity can be fully contacted with the negative pressure meter extension pipe body 1, and the negative pressure meter body can be fully contacted with the negative pressure meter outer surface 1, and the soil meter can be well contacted with the soil meter.
Then, an operator can open the second electromagnetic valve 19 to close the first electromagnetic valve 16 and rotate the threaded sleeve 24 upwards, so that the threaded sleeve 24 pulls the track block 23 to move upwards, at this time, the movable block 14 moves upwards in the cavity 13, at this time, because the second electromagnetic valve 19, the mounting pipe 20 and the air bag block 18 are communicated with the inside of the cavity 13, at this time, air in the air bag block 18 can enter the inside of the cavity 13 through the mounting pipe 20 and the second electromagnetic valve 19, so that the appearance of the air bag block 18 is contracted, then the operator can pull the sealing jacket 28 upwards, so that the operator can drive the negative pressure meter extension pipe body 1 and the ceramic head body 2 to separate from the hole of the soil, at this time, a water source attached to the outer surface of the negative pressure meter extension pipe body 1 can play a good lubricating role, the abrasion between the outer surface of the negative pressure meter extension pipe body 1 and the hole of the soil is effectively reduced, the service life of the whole negative pressure meter extension pipe body 1 is prolonged, and finally the negative pressure meter extension pipe body 1 can be taken out from the soil hole.
