A storage box 18 for placing a sewage sampling tube 17 is provided on the other side of the partition. A controller 19 connected to the electric winding disk 11 is provided at the front end of the portable box 1. Considering that the existing sewage detection sampling device has a relatively complex structure and most of the sampling detection devices are relatively large in size, it often takes a lot of time and preparation work when using it, which is very inconvenient to use, and is not conducive to the staff going out for sampling. And when the sampling location is When working in a vertical shaft, the pipe or connecting rope used to connect the sampling head is prone to friction with the well wall, increasing the disadvantage of the loss rate of the pipe or the connecting rope. The parts of the utility model can be stored in the portable box 1, the functional frame 2 and the storage frame 3, which makes it convenient for the detection personnel to carry the equipment to the detection point to collect sewage samples. Secondly, the device uses the well wall anti-scratch component to cooperate with the alignment component to prevent the connecting rope installed with the sampling bottle 15 from scratching the well wall and the side wall of the portable box 1 during the unwinding and rewinding process, causing wounds and affecting the service life.

[0040] Among them, the wellbore anti-scratch assembly includes a connecting plate 20, an extension plate 21, a first return spring 22, a first stud 23 and an annular rail 24.

The first stud 23 penetrates through the relief groove at the upper end of the connecting plate 20 and is connected to a nut. Protective pads 25 are bonded to the contact surfaces of the two extension plates 21 and the wellbore. In order to reduce the situation that the connecting rope or connecting pipe of the existing sampling equipment is prone to scratching and wear with the wellbore when sampling sewage in a vertical shaft, the wellbore anti-scratch assembly, in cooperation with the alignment assembly and the guide wheel 16, plays a role in protecting the connecting rope or connecting pipe. The reserved hole in the middle of the wellbore anti-scratch assembly can be used for the operation of winding or unwinding the connecting rope. The existence of the annular rail 24 is to facilitate adjusting the use position of the leveling assembly according to the use position of the equipment. When the wellbore anti-scratch assembly is in use, the connecting plate 20 is placed in the middle of the wellhead. Then, the nut is loosened, and the first return spring 22 resets so that the two extension plates 21 abut against the wellbore of the vertical shaft. At this time, the protective pads 25 of the two extension plates 21 are in contact with the wellbore to complete the abutting process. Finally, the nut outside the first stud 23 is tightened so that the use positions of the two extension plates 21 are fixed.

[0041] Among them, the leveling component includes a sleeve rod 26, an L-shaped extension 27, a second return spring 28, a second stud 29, a slider 30, a first positioning bolt 31 and a second positioning bolt 32.

When in use, the four lifting components are turned to open so that the four sleeves 39 are perpendicular to the ground, and then the nut on the outside of the third stud 44 is loosened. At this time, the third reset spring 45 resets and drives the plug-in rod 40 to move downward, and then the nut on the outside of the third stud 44 is tightened to fix the use position of the plug-in rod 40. Then the user inserts the U-shaped rod 46 into the interior of the sleeve block 47. At this time, the use angles of the four sleeves 39 are fixed. Finally, the plug-in rod 40 is inserted into the ground and the contact ring 42 contacts the ground.

[0045] Among them, handles are fixed to the outside of the two movable plates 7, and a sponge block 48 is fixed to the inner side of one of the movable plates 7, which contacts the side of the storage box 18.
