The natural height of the percolate liquid level is obtained through a liquid level meter arranged in a landfill, then an instruction is sent to an intelligent controller 409, then the intelligent controller 409 controls an electromagnetic bolt 502 to operate, the electromagnetic bolt 502 is separated from a limit gear 503, then the intelligent controller 409 controls a driving motor 505 to operate, then the driving motor 505 rotates with a transmission rod 65, then the transmission rod 65 rotates with a rotating disc 67, simultaneously the transmission rod 65 rotates with a cylindrical sleeve 64 through a torsion force 66, then the cylindrical sleeve 64 rotates with a rotating rod 62, then the rotating rod 62 rotates with a reel 63, then the linkage 511 winds to the outside of the reel 63 or the linkage 511 is released from the outside of the reel 63, the position of a counterweight floating ball 512 is controlled through the length of the released linkage 511, the counterweight floating ball 512 is positioned below the natural liquid level, then the intelligent controller 409 controls the driving motor 505 to stop operating, then the electromagnetic bolt 502 stops operating, then the electromagnetic bolt 502 is meshed with the limit gear 503, then the transmission rod 65 is fixed, and then the percolate generated inside the landfill 11 passes through the gap inside the filter layer 14, The percolate collecting hole 22 enters the percolate collecting cylinder 21, the percolate is collected above the sealing piston 32, the liquid level of the percolate inside the percolate collecting cylinder 21 is gradually raised, the counterweight floating ball 512 is immersed in the percolate and subjected to buoyancy, the downward pulling force exerted by the counterweight floating ball 512 on the piston disc case 501 through the linkage 511, the reel 63, the rotating rod 62, the bearing frame 61 and the plug tube 506 is reduced, the piston disc case 501 is moved upwards under the elastic force of the jacking spring 500, the piston disc case 501 is then moved upwards with the conical tapping head 504, the conical tapping head 504 applies an upward jacking force to the contact elastic sheet 404, the contact elastic sheet 404 is then bent upwards and contacted with the other contact elastic sheet 404, the intelligent controller 409 detects the condition and controls the operation of the air blower 410, and then the air passes through the ventilation hole 407 under the driving of the air blower 410, A blower 410, a pressure maintaining structure 7, The air blast pipe 411 enters the positioning cylinder 23 and is discharged into the elastic rubber pipe 31 from the air diversion pipe 24, then the air pressure in the elastic rubber pipe 31 is increased, then the sealing piston 32 moves upwards under the action of the air pressure jacking force, then the sealing piston 32 pulls the elastic rubber pipe 31, the elastic rubber pipe 31 stretches elastically in the vertical direction, meanwhile, the elastic rubber pipe 31 is attached to the inner wall of the percolate collecting cylinder 21 under the action of the air pressure, then the sealing piston 32 pushes the percolate at the top of the sealing piston to move upwards to a high position, meanwhile, the elastic rubber pipe 31 blocks the percolate collecting hole 22 below the sealing piston 32, in the process, the balance weight floating ball 512 rises together with the liquid level, the cylindrical sleeve 64 rotates with the reel 63 through the rotating rod 62 under the action of the torsion force of the torsion spring 66, the linkage line 511 is wound outside the reel 63 to ensure that the linkage line 511 is in a tightening state, then the liquid level contactor 402 is contacted with the liquid level, then the liquid level contactor 402 sends an electric signal to the intelligent controller 409 to ensure that the intelligent controller 409 knows that the liquid level of the percolate is contacted with the bottom surface of the closed-end plug 401, then the sealing piston 32 continuously moves upwards under the action of air pressure, the air pressure sensor 703 monitors the air pressure inside the elastic rubber tube 31 in real time, at the moment, the intelligent controller 409 can control the pressure of the sealing piston 32 on the percolate column according to the requirement, further control the recharging speed, then the sealing piston 32 extrudes the percolate column, and then the percolate passes through the percolate collecting hole 22 at the high position, The gap inside the filter gravel layer 14 is reverse-permeated into the garbage buried layer 11 to realize the recharging effect, then the top end of the distance rod 33 is contacted with the bottom surface of the closed plug 401, then the leachate is recharged continuously at a high position, then the liquid level descends, then the liquid level contactor 402 is separated from the liquid level, then the intelligent controller 409 controls the air blower 410 to be closed and controls the electromagnetic air valve 710 to be opened, and then the air inside the elastic rubber tube 31 passes through the shunt air tube 24, the positioning cylinder 23, the air blowing tube 411, the pressure maintaining cavity 702 under the action of pressure difference, The vent hole 706 acts on the top surface of the closing piston 708, then the closing piston 708 moves downwards under the action of pressure difference, then the closing piston 708 moves downwards with the positioning rod 709, then the bottom end of the positioning rod 709 is propped against the bottom surface of the inner cavity of the air release cavity 704, at the moment, the cavities on the upper side and the lower side of the closing piston 708 are communicated through the air release groove 705, then high-pressure air is discharged from the electromagnetic air valve 710, then the air pressure difference on the upper side and the lower side of the closing piston 708 is gradually reduced, then the closing piston 708 moves upwards under the action of the elastic force of the pressure-retaining spring 707 and blocks the top end of the air release cavity 704, and at the same time, the sealing piston 32 is arranged on the elastic rubber tube 31, The pulling spring 34 moves downwards under the action of elastic pulling force until the bottom surface of the sealing piston 32 is contacted with the top surface of the positioning cylinder 23.
