[0024] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] A sulfide black wastewater sampling device, such as Figure 1-Figure 4 As shown, it includes a shell 1, a sampling cup 11, a fixing claw 12, a handle 2, a connecting rod 21, a pull rope 22, a first stopper 23 and a spring 24. The shell 1 is divided into three areas from top to bottom, and the three areas are separated from each other. The shell 1 is detachably connected to three sampling cups 11, and each area of ​​the shell 1 is distributed with a sampling cup 11, and a groove is provided on the sampling cup 11. The shell 1 is rotatably connected with a plurality of fixing claws 12, and the fixing claws 12 fit with the grooves of the sampling cup 11. Each area of ​​the shell 1 is distributed with two fixing claws 12, and the two fixing claws 12 are respectively located on both sides of the sampling cup 11. Torsion springs are provided on both sides of the fixing claws 12, and the two sides of the torsion springs are respectively connected to the fixing claws 12 and the shell 1, and the torsion springs can The fixed claw 12 is able to clamp the sampling cup 11. A connecting rod 21 is slidably connected to the rear of the shell 1. A handle 2 is connected to the top of the connecting rod 21. The handle 2 can facilitate the staff to pull the connecting rod 21. The connecting rod 21 is connected to three pull ropes 22. The front side of each area of ​​the shell 1 is slidably connected to a first stopper 23. The three pull ropes 22 are respectively connected to the three first stops 23. A slideway is provided inside the shell 1. The pull rope 22 slides in the slideway. The length of the pull rope 22 is the same as the length of the slideway, so that the pull rope 22 can pull the first stopper 23. A spring 24 is provided on the first stopper 23. The two ends of the spring 24 are respectively connected to the shell 1 and the first stopper 23. The spring 24 is used to reset the first stopper 23.

[0027] When it is necessary to sample the sulfide black wastewater, the wastewater may be stratified due to the uneven distribution of pollutants in the wastewater. In order to detect the distribution of pollutants, the device is divided into three areas, each of which can be installed with a sampling cup 11. The fixed claw 12 is pulled, and the torsion spring in the fixed claw 12 is twisted and deformed, and the sampling cup 11 is inserted into the shell 1. Then the torsion spring in the fixed claw 12 is reset, so that the fixed claw 12 clamps the sampling cup 11, and then the device is slowly placed in the wastewater. After the device is completely immersed in the wastewater, the handle 2 is pulled to drive the connecting rod 21 to move upward. The connecting rod 21 can pull the pull rope 22, thereby moving the first stopper 23 upward, so that the shell 1 is connected to the outside world, and the spring 24 is compressed. At this time, the wastewater can enter the shell 1 and flow into each sampling cup 11. After the collection is completed, the handle 2 is released, and the spring 24 is reset from the compressed state, thereby driving the first baffle to move downward, and re-blocking the inside of the shell 1. Then the device is taken out of the wastewater, and the fixed claw 12 is pulled to extract the sampling cup 11.

[0028] Example 2

[0029] On the basis of Example 1, Figure 5-Figure 8 As shown, it also includes a floating plate 3, a second stopper 31, a guide rod 32, an air bag 4, an air cylinder 41 and an air guide tube 42. Two symmetrical guide rods 32 are provided inside each area of ​​the shell 1. The floating plate 3 is slidably connected between the two guide rods 32. A plurality of circular holes are opened on the floating plate 3. Wastewater can directly flow into the sampling cup 11 through the circular holes of the floating plate 3. The floating plate 3 is connected to the second stopper 31. Two air bags 4 are provided in each area of ​​the shell 1. The air bags 4 are inflatable and used to fill the gap between the shell 1 and the sampling cup 11. Two air cylinders 41 are installed in each area of ​​the shell 1. The two air cylinders 41 are respectively connected to the corresponding air bags 4 through the air guide tube 42. The sampling cup 11 can push the piston rod of the air cylinder 41.

[0030] During the process of wastewater entering the shell 1, as the water level of the wastewater in the shell 1 rises, the float plate 3 can move upward with the wastewater, and the float plate 3 can drive the second stopper 31 to move upward. The second stopper 31 can further block the opening of the shell 1 to prevent the first stopper from failing to completely separate the wastewater, thereby causing wastewater from different areas to mix and enter the shell 1. In order to prevent wastewater from overflowing from the gap between the shell 1 and the sampling cup 11, during the process of inserting the sampling cup 11 into the shell 1, the sampling cup 11 can push the piston rod of the air cylinder 41, so that the air in the air cylinder 41 is injected into the air bag 4 through the air guide tube 42. The air bag 4 can fill the gap between the sampling cup 11 and the shell 1, thereby increasing the sealing of the shell 1.

Therefore, the scope of the present invention should be limited only by the appended claims.
