[0024] The water source in the foundation pit can be transported to the inside of the working cylinder 1 through the water inlet pipe 3, and the water inlet pipe 3 will transport the water source to the top of the interception net 9. The interception net 9 will intercept some impurities in the water source, so that they are filtered and gathered on the surface of the interception net 9, and the rotary pressing mechanism will rotate and roll some impurities on the interception surface of the interception net 9 through the pressing end, so that the water source can flow to the bottom of the interception net 9 more quickly.

[0025] In addition, a motor 7 is installed on the top of the working cylinder 1, and a rotating shaft 8 is fixedly connected to the output end of the motor 7. The rotating shaft 8 is driven to rotate by the motor 7.

[0026] Furthermore, the above-mentioned rotary pressing mechanism includes: a pressure roller 11, wherein a support plate 10 is fixedly connected to the rotating shaft 8, the pressure roller 11 is rotatably connected to the support plate 10, and the pressure roller 11 is in contact with the interception surface of the interception net 9, and a connecting shaft 13 is rotatably connected to the support plate 10, and the connecting shaft 13 is transmission-connected to the pressure roller 11 through a pulley; a gear ring 12, fixedly connected to the inner wall of the working cylinder 1, wherein a connecting rod 14 is rotatably connected to the support plate 10, and the connecting rod 14 is transmission-connected to the connecting shaft 13 through a bevel gear, and a connecting gear 15 is fixedly connected to the top of the connecting rod 14, and the connecting gear 15 is meshed with the gear ring 12.

[0027] When the motor 7 drives the rotating shaft 8 to rotate, the rotating shaft 8 can drive the supporting plate 10 to rotate synchronously.

[0029] In addition, when the rotating shaft 8 rotates, the spiral plate 20 will rotate synchronously to stir the water source at the bottom of the working cylinder 1 and put it in a flowing state. A circulating conveying mechanism is arranged in the working cylinder 1, and a diversion channel 17 is opened in the rotating shaft 8.

[0031] The water source in the disinfection box 36 is transported to the conveying plate 19 through the telescopic tube 41, so that the water source containing the disinfectant liquid and the unsterilized water source are preliminarily mixed.

[0032] In addition, the mixing and stirring mechanism provided in the disinfection box 36 can repeatedly mix and stir the water source and the liquid medicine, so that the liquid medicine can be integrated into the water source more quickly, thereby improving the treatment efficiency of drainage.

[0033] Furthermore, the above-mentioned mixing and stirring mechanism includes a stirring rod 37 rotatably connected to the disinfection box 36, a stirring paddle 40 is fixedly connected to the outer wall of the stirring rod 37, an extension shaft 28 is rotatably connected to the side wall of the disinfection box 36, one end of the extension shaft 28 extends into the disinfection box 36 and is fixedly connected to a first blade 29, and the other end of the extension shaft 28 extends into the working cylinder 1 and is fixedly connected to a second blade 30, the first blade 29 cooperates with the stirring paddle 40, and the second blade 30 cooperates with the spiral plate 20.

During this process, the air inlet pipe will stop taking in air under the action of the one-way valve, and the air outlet pipe will exhaust air under the action of the one-way valve. At the same time, the reset spring 34 is compressed, and the gas entering the liquid storage cylinder 35 will pressurize the interior, and the liquid storage cylinder 35 transports the internal medicine liquid to the disinfection box 36 through the pipeline.

[0038] When the movable block 25 moves in the opposite direction of the boosting cylinder 32, the reset spring 34 will drive the boosting rod 33 to reset, and the air inlet pipe will take air into the boosting cylinder 32 under the action of the one-way valve, while the air outlet pipe will stop exhausting air under the action of the one-way valve, so that the medicine liquid can be intermittently transported into the boosting cylinder 32, so that the water source can be mixed with the medicine liquid.
