When the device is used, a hauling rope is connected with a sampling device through a worker, the sampling device is placed in water, and as the two groups of collecting holes 31 and the two extracting pipes 1 are arranged, the two extracting pipes 1 are mutually different, so that samples are collected from two angles after the sampling device is placed in water, and experimental data comparison is facilitated.
Because the pressure in the extraction pipe 1 is less than external pressure, rivers are collected in the extraction pipe 1 along gathering hole 31, produce suction around gathering hole 31 for the rivers are caused the impact to the expansion ring 45 when being inhaled, promote the expansion ring 45 and make it slide on the snap ring 42 surface, because dredge the shape of pipe 43 and be round platform form when the expansion ring 45 slides, the pipe diameter at both ends is different, and the expansion ring 45 laminating is at dredge the internal surface of pipe 43, and expansion ring 45 presents indent form with snap ring 42, is convenient for play the water conservancy diversion effect to rivers.
When a worker puts the sampling device into water, because the pressure in the extracting pipe 1 is different from the external pressure, the pressure in the extracting pipe 1 is lower than the external pressure, suction is generated around the collecting hole 31 to enable water flow to be sucked into the extracting pipe 1 along the dredging pipe 43, when the water flow is sucked, the water flow is collected from the periphery to the collecting hole 31, the sliding blocks 41 on two sides are pushed to slide towards the middle by the water flow, the connecting blocks 44 slide out from the clamping rings 42, the effect that impurities with larger volume in the water body are blocked outside the collecting hole 31 through the sliding blocks 41 on two sides is achieved, the phenomenon that the impurities with larger volume are sucked into the collecting hole 31 is avoided, the sampling device is blocked, and the sampling efficiency is affected is avoided.
Because the telescopic ring 45 is connected with the outer ring 32, and the outer ring 32 is flexibly connected with the fixed disk 33, when the telescopic ring 45 is attached to the loose tube 43 to slide, the fixed disk 33 is driven by the outer ring 32 to slide on the surface of the limiting spring frame 35.
The limiting spring frame 35 is connected to the inner wall of the dredging pipe 43 through a positioning rod 36, and the fixed disc 33 is limited by the limiting spring frame 35 when sliding, so that the limiting spring frame 35 is extruded.
The locating lever 36 is connected at the inner wall of dredging pipe 43, when fixed disk 33 slides, circle piece 353 receives fixed disk 33 to push and slides on separation ring 34 surface, buckle pad 351 receives the extrusion to produce deformation, buckle produces between pad 351 and the subsides piece 354 and buckles, circle piece 353 slides to stopper 352 surface along with buckling pad 351, restriction position piece 352 restriction stops inwards sliding, because circle piece 353 and stopper 352 are the rubber material, reach when fixed disk 33 receives the rivers impact, can strengthen fixed disk 33 bearing force, be convenient for when the rivers of different degree of depth and pressure are assembled, fixed disk 33 receives external factor influence to produce dislocation with flexible ring 45, influence the sampling rate.
The water flows through the baffle ring 34 along the collecting hole 31 and then flows into the dredging pipe 43, and because a large amount of impurities are contained in the water body, when the sampling device is placed in water, the impurities are easily adsorbed on the inner wall of the collecting hole 31, so that the sliding member 345 is arranged on the surface of the sliding ring 344, and when the water flow is sucked into the collecting hole 31, the pressure in the water flow and the water body pushes the sliding member 345 to slide on the surface of the sliding ring 344 and generate friction with the friction ring 342, so that the impurities around the collecting hole 31 are removed.
In the process of placing the sampling device in water and taking out the sampling device from the water, the pressure in water flow and water pushes the slide rod 3454, so that the slide rod 3454 drives the friction ring 3452 to slide on the surface of the slide ring 344, the slide rod 3454 scrapes impurities on the surface of the slide ring 344, the friction ring 3452 slides on the surface of the friction ring 342, the friction ring 3452 is of a multi-section structure, strip impurities can be hooked out, and the hooked strip impurities are not easy to wind and drop due to the smooth surface of the friction ring 3452, so that different impurities can be cleaned conveniently during sampling, the impurity content in a water sample is reduced, and meanwhile, the large-volume impurities are prevented from entering the extraction pipe 1 to cause abrasion of a pipe body.
