Embodiment 1

[0024] A telescopic surface water nearshore water quality sampler, which uses a telescopic sampling rod 8 as the main body of the sampler, and a seven-button bottle clip 7 is installed at its front end for fixing, and the main body of the sampler includes a telescopic sampling rod 8 and a fixed plate 6; wherein the sampling rod is composed of multi-section telescopic arms with scales, the adjacent two telescopic arms are fixed with locking rings, the rear end of the telescopic rod has a handle, and the front section has a fixed nut, which can be fixed with a screw plate. The sampling rod plate consists of a handle 1, a three-section retractable telescopic arm 2 with scales, a locking ring 3, and a front nut 4; the fixing plate 6 (plexiglass plate) is fixed together by the fixing screw 5 and the retractable sampling rod, and the seven-button bottle Clip 7, with a diameter of 2.8 cm, is also fixed on the fixed plate by screws. The sampling bottle is a 3cm sampling bottle. Then...

Embodiment 2

[0026] A telescopic surface water near-shore water quality sampler, which adopts a telescopic sampling rod 8 as the main body of the sampler, and installs a seven-button bottle clip 7 at its front end for fixing, wherein the sampling rod is made of a multi-section telescopic belt The scale telescopic arm is composed of two adjacent telescopic arms fixed with locking rings, a handle at the rear end of the telescopic rod, and a fixing nut at the front section, and a connecting plate can be fixed with screws. The sampling rod plate consists of a handle 1, a three-section retractable telescopic arm 2 with scales, a locking ring 3, and a front nut 4; the fixed plate 6 is fixed together by a fixing screw 5 and a retractable sampling rod, and a seven-button bottle clamp 7, with a diameter of 2.8 cm, the sampling bottle is a 5cm sampling bottle. It is also fixed on the fixed plate by screws. Then adjust the length of the telescopic rod according to the sampling distance to achieve th...

Embodiment 3

[0028] Actual sampling situation:

[0029] Fix the sampling bottle on the seven-button bottle clamp, and adjust the length of the telescopic rod according to the actual situation on site ( figure 2 ), extend the water sampling bottle to the collected water surface, press down the telescopic rod, make the water sampling bottle submerged below the water surface and fill it with water samples, then seal the water sampling bottle, remove the water sampling bottle, and complete the water sample collection. The sampler can be equipped with sampling bottles of different materials according to the requirements of the test items. Compared with ordinary water collectors, it has no effect on the accuracy of the test results.

Abstract

The invention discloses a telescopic surface water and coastal water quality sampler. In the telescopic surface water and coastal water quality sampler, a telescopic sampling rod is taken as a sampler main body; a seven-buckle bottle clamp is arranged at the front end of the sampler main body for fixing a sampling bottle; the sampling rod consists of three segments of graduated telescopic arms; two adjacent segments of telescopic arms are fixed by using a locking ring; the rear end of the telescopic rod is provided with a handle; a fixing nut is arranged at the front segment of the telescopic rod, and a connecting plate can be fixed by using a screw; the telescopic rod can be made of carbon, stainless steel or aluminum alloy, so that different load bearing conditions are satisfied. The length of the telescopic rod can be adjusted, so that horizontal-distance sampling can be performed in coastal water areas. The distance between a sampled water sample and the coast can be acquired according to graduations marks on the telescopic rod. The seven-buckle bottle clamp is arranged at the front segment of the telescopic rod, and the sampling bottle can be arranged on the seven-buckle bottle directly, conveniently and rapidly. The sampler has the characteristics of easiness and convenience in operation during water quality sampling, convenience in carrying and capability of satisfying sampling of different distances. The working difficulty is lowered for environmental detection workers. Moreover, one water sample is filled into one bottle, so that the water sample is prevented from being polluted.

Description

technical field [0001] The invention belongs to the technical field of water quality monitoring and analysis, and relates to a telescopic surface water nearshore water quality sampler, which can be applied to surface water collection in nearshore places such as wild rivers, lakes, reservoirs and seasides. Background technique [0002] Field water sample collection is a prerequisite for scientific research on water environment issues, and in the sampling process, the quality of the water sample collector is crucial to the efficiency of field water sample collection. At present, for water quality sampling in nearshore areas, in order to obtain water samples that meet the requirements, most water quality inspectors need to go into the water or throw the sampler into a place relatively far away from the shore to collect water samples when performing water quality sampling inspections. , There is also a water scoop that uses a longer handle to collect the water sample and then pa...
