Surface water sample collector

Abstract

The invention discloses a surface water sample collector comprising a sampling bottle, supporting rods, a cross rod, a handle bar, a bottle plug, a water outlet pipe and a ball sealer, wherein one ends of the two supporting rods are connected with two side surfaces of the collecting bottle, respectively, the cross rod is fixed at the top of the collecting bottle, the other end of each of the two supporting rods is connected with the cross rod, the handle bar is connected with the cross rod, a water inlet is formed in the bottom of the collecting bottle, the bottle plug is arranged in the water inlet, the water outlet pipe is arranged on the bottle plug, the ball sealer is arranged in the collecting bottle, and the density of the ball sealer is larger than that of water. The surface water sample collector disclosed by the invention can be used for flexibly controlling the depth during sampling so as to prevent aquatic plants and suspended matter in water from entering the bottle, also can be used for testing the temperature when used for collecting surface water, is less prone to pollution, has the characteristics of portability, flexibility and simplicity in operation, and can be used for improving the sampling precision and efficiency without increasing the labor intensity of monitoring operators.

Description

technical field [0001] The invention relates to a water sample collecting device, in particular to a surface water sample collecting device. Background technique [0002] Some current collectors usually require that the water body at the sampling point is free of weeds or other large particles of solid impurities when collecting, while field ditches usually have more aquatic plants and other weeds and suspended solids in the water body, which may easily lead to inconvenient operation of water collection. 1. The sampling bottle cannot enter the water, resulting in insufficient water collection, which is easy to bring in suspended impurities, which makes field sampling difficult. After the sampling is completed, the collected water samples need to be transferred. In the process of transferring the collected water samples, it is necessary to turn the sampler upside down and discharge water from the upper end, resulting in water sample transfer. It is easy to mix with gas, which...

[0002] Some current collectors usually require that the water body at the sampling point is free of weeds or other large particles of solid impurities when collecting, while field ditches usually have more weeds such as aquatic plants and suspended solids in the water body, which may easily lead to inconvenient operation of water collection. 1. The sampling bottle cannot enter the water, resulting in insufficient water collection, which is easy to bring in suspended impurities, which makes field sampling difficult. After the sampling is completed, the collected water samples need to be transferred. In the process of transferring the collected water samples, it is necessary to turn the sampler upside down and discharge water from the upper end, resulting in water sample transfer. It is easy to mix with gas, which will cause interference in the test of certain indicators, and may also increase the risk of sample contamination in the process
