[0039] In the embodiment, when in use, the cannula 9 is inserted into the quick connector sleeve 6 and connected through the plurality of positioning strips 22 and the strip-shaped slot 23. The unlocking sleeve 13 is rotated to move the plurality of clamping blocks 8 into the arc-shaped slot 26. The plurality of push springs 31 pushes the push plate 30, and the plurality of push plates 30 pushes the plurality of clamping blocks 8 to be clamped in the clamping slot 10. Then, the rotating sleeve 11 is rotated to push the clamping block 8 in the movable hole 7 through the plurality of push blocks 12, and the cannula 9 is pushed to make the sealing ring 24 arranged on the outer wall of the cannula 9 extrude against the inner wall of the quick connector sleeve 6, and the cannula 9 extrudes against the extrusion pad 25. The plurality of extrusion springs 36 pushes the positioning block 37 to be clamped in the positioning slot 38 to position the rotating sleeve 11. The connection between the cannula 9 and the quick connector sleeve 6 is completed. Then, the extraction pipe 2 is deeply inserted into the percolation tank, the water pump 1 is started to extract the percolate, and then the percolate is input into the teahouse through the output end of the water pump 1. The plurality of hole seals 18 and the sealing plate 14 are pushed by the water pressure, the plurality of sealing blocks 15 slide out of the hole seal, the sealing plate 14 is separated from the abutment with the connecting sleeve 3, and the connecting plate 20 is pulled by the limiting rod 16 to compress the compression spring 21, so that a flow space is formed in the connecting sleeve 3, and the percolate flows into the collection barrel 4. After the extraction is completed, the connecting plate 20 is pushed by the reset of the compression spring 21 and the sealing plate 14 is driven by the limiting rod 16 to abut against the outside of the connecting sleeve 3, and the plurality of sealing blocks 15 are inserted into the hole seal 18 to seal the connecting sleeve 3.

[0040] More specifically, when the cannula 9 needs to be separated from the quick connector sleeve 6, the rotating sleeve 11 is rotated to compress the plurality of extrusion springs 36 by sliding the positioning block 37 into the movable slot 35 through the plurality of positioning slots 38, so that the plurality of push blocks 12 are separated from the plurality of clamping blocks 8, the plurality of clamping blocks 8 are separated from the cannula 9, the unlocking sleeve 13 is rotated to make the plurality of clamping blocks 8 separate from the arc-shaped slot 26, the plurality of clamping blocks 8 are separated from the clamping slot 10, and the plurality of push springs 31 are extruded by the push plate 30. Thus, the plurality of clamping blocks 8 can be separated from the cannula 9, and the cannula 9 can be pulled out of the quick connector sleeve 6. Then, the collection barrel 4 can be transported later by the transport vehicle 5.

[0041] In summary, during use or operation of the overall equipment: When in use, the insertion tube 9 is inserted into the quick-connect sleeve 6, and then connected to the slot 23 via multiple sets of positioning strips 22. Rotating the unlocking sleeve 13 moves multiple sets of locking blocks 8 into the arc-shaped groove 26. Multiple sets of push springs 31 push the push plate 30, which in turn pushes the locking blocks 8 into the slot 10. Then, rotating the rotating sleeve 11 pushes the locking blocks 8 through multiple sets of push blocks 12, causing them to slide within the movable hole 7 and push the insertion tube 9. This causes the sealing ring 24 on the outer wall of the insertion tube 9 to press against the inner wall of the quick-connect sleeve 6. Simultaneously, the insertion tube 9 presses against the compression pad 25. Multiple sets of compression springs 36 push the positioning block 37 into the positioning groove 38 to position the rotating sleeve 11, thus completing the connection between the insertion tube 9 and the slot 6. Connect the quick-connect sleeve 6, then insert the extraction tube 2 into the percolation tank, start the water pump 1 to extract the leachate, and then the leachate is input into the teahouse through the output end of the water pump 1. The water pressure pushes the multiple sets of sealing holes 18 and sealing plates 14, causing the multiple sets of sealing blocks 15 to slide out of the seal. The sealing plates 14 disengage from the connecting sleeve 3. At the same time, the limiting rod 16 pulls the connecting plate 20 to compress the compression spring 21, so that a flow space is formed in the connecting sleeve 3, allowing the leachate to flow into the collection tank 4. After extraction, the compression spring 21 is reset and pushes the connecting plate 20, and the limiting rod 16 drives the sealing plate 14 to abut against the outside of the connecting sleeve 3. At the same time, the multiple sets of sealing blocks 15 are inserted into the sealing holes 18 to seal the connecting sleeve 3.

[0042] When it is necessary to separate the cannula 9 from the quick-connect sleeve 6, rotate the rotating sleeve 11. Through the multiple sets of positioning grooves 38, push the positioning block 37 to slide into the movable groove 35 to compress the compression spring 36. This causes the multiple sets of push blocks 12 to release their contact with the multiple sets of locking blocks 8, thus releasing the multiple sets of locking blocks 8 from pushing the cannula 9. Rotate the unlocking sleeve 13 to make the multiple sets of locking blocks 8 disengage from the arc groove 26. This causes the multiple sets of locking blocks 8 to disengage from the locking groove 10 and, through the push plate 30, to compress the multiple sets of push springs 31. This releases the multiple sets of locking blocks 8 from the cannula 9, allowing the cannula 9 to be pulled out of the quick-connect sleeve 6. Then, it can be transported to the collection bucket 4 by the conveyor 5.

[0043] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
