[0025] The specific settings and functions of this embodiment are described in detail below. When it is necessary to sample and collect sewage at the bottom of the sewage pipe, the bottom sewage collection device is first placed directly above the sewage pipe, and then a suitable number of weight blocks 23 are placed inside the weight placement slot 22, the gravity of the extrusion bin 2 is adjusted, and the drive component 121 is started. The drive component 121 drives the take-up wheel 12 to rotate, and the steel wire 13 is lowered. The steel wire 13 is fixedly connected to the outside of the No. 1 hanging ring 22, so that the bottom of the extrusion bin 2 slides to the bottom of the sewage pipe, and the solid waste at the bottom of the sewage pipe is squeezed, so that the solid waste is isolated on the outside of the extrusion bin 2.

In addition, since the toggle block 231 is slidably engaged in the inside of the limit slot 221, the limit slot 221 will limit the weight block 23 by limiting the horizontal movement of the toggle block 231, thereby preventing the weight block 23 from shaking inside the weight placement slot 22.

[0029] The use method and working principle of the device: when it is necessary to sample and collect sewage at the bottom of the sewage pipe, first place the bottom sewage collection device just above the sewage pipe, then place a suitable number of weight blocks 23 inside the weight placement slot 22, adjust the gravity of the squeezing bin 2, start the drive assembly 121, and the drive assembly 121 drives the take-up wheel 12 to rotate, and put down the steel wire 13. Since the steel wire 13 is fixedly connected to the outside of the No. 1 lifting ring 222, the bottom of the squeezing bin 2 slides to the bottom of the sewage pipe, squeezing the solid waste at the bottom of the sewage pipe so that the solid waste is isolated outside the squeezing bin 2. The sewage to be sampled will enter the inside of the squeezing bin 2 through the water inlet circular hole 21, and the water pump will pump the sewage out from the bottom of the sewage pipe through the sampling tube 31 to complete the sampling operation;
