When it is necessary to stir the sludge at the bottom of the well water, the stirring mechanism 8 is placed at a suitable depth, and the second motor 804 is turned on to make the rotating column 805 rotate. The rotation of the stirring plates 806 can disturb the water, thereby disturbing the sludge at the bottom of the well water.

[0031] Please see Figure 1 and Figure 6 In this embodiment, the stirring mechanism 8 further includes a battery 807, a controller 808, a wireless transceiver 809, and a sealed box 810.

[0033] Working principle: First, place the movable plate 3 under the U-shaped frame 1, turn on the electric cylinder 101 to move the push block 102, and use the four clamping blocks 103 to clamp the movable plate 3. At this time, the upper end of the bearing block 104 and the lower end of the movable plate 3 are in contact, which can support the movable plate 3.

[0034] Then, the winding mechanism on the upright block 4 is activated to lower the sampling cylinder 701. By activating the first motor 403, the take-up reel 402 is rotated, and the rope 404 is wound onto the take-up reel 402, thereby raising and lowering the sampling cylinder 701.

[0035] When it is necessary to stir the sludge at the bottom of the well water, after placing the stirring mechanism 8 at a suitable depth, the second motor 804 is turned on to make the rotating column 805 rotate. The rotating stirring plate 806 can disturb the water, thereby disturbing the sludge at the bottom of the well water.

[0036] The stirred mixture will enter the sampling tube 701 through the water inlet tank 704 for temporary storage, and the threaded tube 703 can be easily removed from the winding mechanism for quick sampling of wastewater. The sampled liquid is placed in the wastewater detector 5, and the wastewater detector 5 can be turned on to detect the wastewater.

[0037] In addition, when not in use, the sampling tube 701 can be placed on the inner wall of the placement hole 12. At this time, the lower end of the fixing ring 702 and the upper end of the movable plate 3 are in contact, which is conducive to the stable placement of the sampling tube 701.

[0038] In use, the rope 404 can also be passed through the through hole 603 and the second oblique hole 904 and released downwards. At this time, the sampling mechanism 7 will be located outside the U-shaped frame 1, making it convenient to observe the position of the sampling mechanism 7.
