[0002] Waste water detection is an important part of environmental monitoring work. It is a process of real-time monitoring of the pollutant concentration and change trend in waste water, aiming to ensure water quality safety, protect the ecological environment, and provide an important basis for waste water treatment and water quality management. It evaluates the water quality status of waste water by qualitatively and quantitatively analyzing the pollutants in the waste water, determines whether it meets the national or local water quality standards, and whether it will pollute the environment.

And a sealing cylinder is arranged inside the sampling cylinder. The water inlet pipes can be sealed by the arranged sealing cylinder. Furthermore, when sampling waste water at a certain depth, due to the sealing effect of the sealing cylinder, waste water can be prevented from flowing into the sampling cylinder before the sampling cylinder reaches the depth of the target waste water, and when the sampling depth is reached, the sealing cylinder is driven to move to open the water inlet pipes, so that waste water can be sampled.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Please refer to Figures 1-4 , an embodiment provided by the present invention: a wastewater sampling device for wastewater detection, including a handle 1, a fixed block 2 is fixedly installed on one side of the handle 1, a telescopic rod 3 is fixedly installed on one side of the fixed block 2, and a sampling cylinder 4 is fixedly installed at the end of the telescopic rod 3 away from the fixed block 2. Both ends of the sampling cylinder 4 are sealed. A sealing cylinder 10 is arranged inside the sampling cylinder 4. The left end of the sealing cylinder 10 is sealed, and the right end is open. The inner wall of the sampling cylinder 4 is attached to the outer wall of the sealing cylinder 10. A sealing gasket is arranged on the outer surface of the sealing cylinder 10 to increase the contact tightness between the sealing cylinder 10 and the sampling cylinder 4. Water inlet pipes 5 are symmetrically and fixedly installed at the front end and the rear end of the sampling cylinder 4 respectively, and the water inlet pipes 5 are communicated with the sampling cylinder 4.

[0024] During use, when sampling wastewater at a certain depth, due to the sealing effect of the sealing cylinder 10, when the sampling cylinder 4 has not reached the depth of the target wastewater, it can prevent wastewater from flowing into the sampling cylinder 4, and when the sampling depth is reached, by driving the sealing cylinder 10 to move to open the water inlet pipe 5, wastewater can be sampled, thus realizing the accurate sampling of wastewater at a certain depth and increasing the practicability of the sampling device.

[0025] Furthermore, a second ring plate 9 is arranged inside the sampling cylinder 4 along one side of the sealing cylinder 10, and the second ring plate 9 is fixedly connected to the sealing cylinder 10. A compression spring 8 is fixedly installed on one side of the second ring plate 9, and a first ring plate 7 is fixedly installed on one side of the compression spring 8, and the first ring plate 7 is fixedly connected to the sampling cylinder 4. Through the arrangement of the compression spring 8, when the sealing cylinder 10 moves, it will drive the compression spring 8 to expand and contract, which is convenient for the sealing cylinder 10 to reset when the acting force applied to the sealing cylinder 10 disappears.

[0026] Furthermore, a third ring plate 14 is fixedly installed inside the sampling cylinder 4 along the other side of the sealing cylinder 10, which can limit the end position of the sealing cylinder 10. A filter screen 13 is fixedly installed inside the water inlet pipe 5, which can prevent large impurities in the wastewater from entering and blocking the water inlet pipe 5, increasing the practicability.

[0027] Further, winding rollers 16 are symmetrically arranged at the front end and the rear end of the fixing block 2 respectively. The winding roller 16 includes a roller body 1601 and ring plates 1602. There are two ring plates 1602, and the two ring plates 1602 are symmetrically and fixedly installed at both ends outside the roller body 1601. A straight shaft 17 is rotatably installed inside the fixing block 2. Both ends of the straight shaft 17 extend out of the fixing block 2, and both ends of the straight shaft 17 respectively penetrate through the roller bodies 1601 of the two winding rollers 16 and are fixedly connected to the two roller bodies 1601 respectively, so that the rotation of the straight shaft 17 can drive the two winding rollers 16 to rotate. A shaft sleeve 18 is fixedly installed on the outer side of the straight shaft 17, and a rocker 19 is fixedly installed on one side of the shaft sleeve 18. A traction rope 15 is wound around the outer side of the roller body 1601. By arranging the ring plates 1602 at both ends outside the roller body 1601, the traction rope 15 can be stably wound on the roller body 1601, increasing the practicability.

[0028] Further, long slot holes 401 are symmetrically arranged on the front end face and the rear end face of the sampling cylinder 4 respectively. Straight rods 11 are symmetrically and fixedly installed at the front end and the rear end of the sealing cylinder 10 respectively. One ends of the two straight rods 11 respectively extend to the outside of the sampling cylinder 4 through the two long slot holes 401. A retaining piece 12 is fixedly installed at one end of the straight rod 11. One end of the traction rope 15 is tied and connected to the straight rod 11, so that by pulling the traction rope 15, the straight rod 11 can be driven to move, and then the sealing cylinder 10 can be driven to move, facilitating the sampling work of the wastewater.

[0029] Further, a drain pipe 6 is fixedly installed on one side of the sampling cylinder 4. A sealing plate 21 is arranged on one side of the drain pipe 6. A sealing column 20 is threadedly installed inside the drain pipe 6, and the sealing column 20 is fixedly connected to the sealing plate 21. A convex plate 22 is fixedly installed on one side of the sealing plate 21. Then, by rotating the convex plate 22, the sealing column 20 is driven to rotate, and the sealing column 20 is moved out of the drain pipe 6, facilitating the discharge of the sampled wastewater and increasing the practicability.

[0030] Working principle: When in use, when sampling is required for wastewater detection, hold the handle 1, and then adjust the overall length by stretching the telescopic rod 3 according to the sampling depth of the wastewater. Then insert the sampling cylinder 4 into the wastewater. By sealing the water inlet pipe 5 with the sealing cylinder 10, the self-flow of the wastewater into the sampling cylinder 4 can be prevented. Then, after the sampling cylinder 4 reaches the sampling depth, rotate the straight shaft 17 through the rocker 19 to make the winding roller 16 rotate, take in the traction rope 15, drive the straight rod 11 to move, drive the sealing cylinder 10 to move through the transmission of the straight rod 11, and the compression spring 8 is compressed under pressure, so as to open the water inlet pipe 5 and make the wastewater flow into the sampling cylinder 4. After the sampling collection is completed, let out the traction rope 15. Under the tension of the compression spring 8, the sealing cylinder 10 resets to seal the water inlet pipe 5. Then take out the sampling cylinder 4 from the wastewater, and then rotate the convex plate 22 to unscrew the sealing column 20 to discharge the wastewater.
