Novel river water quality sampling device

Abstract

The invention discloses a novel river water quality sampling device, which comprises a bottom plate, universal wheels, fixing insertion rods, a push-pull rod, support frames, a telescopic post, a storage battery, collection bottles, a rotating motor, water pipe discs, steel cable discs, a water pipe, a water pumping pump, a steel cable, a clamp block, a telescopic arm, a pull rod, a rotating shaft, positioning rings, a fixed pulley, a collection box, through holes and a filtering screen. The novel river water quality sampling device has the beneficial effects that the support frames are divided into three layers through a separation plate; the mutual work influence is avoided; the water pipe discs and the steel cable discs are arranged on bearings with the same diameters; the rotating motor is connected with the water pipe discs and the steel cable discs through belts, so that the telescopic speed of the water pipe and the steel cable are identical; the telescopic post and the telescopic arm are rotationally connected; the telescopic arm can be conveniently collected and released; a length line is arranged on the steel cable; samples at the required depth can be standardly collected; a load bearing body is arranged at the bottom of the collection box; the through holes of the side wall of the collection box are greater than the diameter of the filtering screen; the sinking to the deep position is convenient; sundries are reduced.

Description

technical field [0001] The invention relates to a sampling device, in particular to a novel river water quality sampling device, which belongs to the technical field of water environment monitoring devices. Background technique [0002] Water is one of the elements that human beings depend on for survival. The state has formulated regulations on water environment quality assessment, forecasting, and forecasting. At present, my country monitors all rivers, reservoirs, etc. that enter surface water bodies and pollutants discharged from production and living facilities. Prevent water pollution, protect and improve the water environment. Now, with the growth of the national economy, the pollution of rivers is getting heavier. Doing a good job in water quality testing is an important factor related to the development of the national economy and the health of the people. In the work of water quality testing, water quality sampling is an important very important link. [0003] Howev...

Problems solved by technology

[0003] However, the structure of the current water quality sampling device is relatively simple. First, it can only collect water samples on both sides of the river bank. The water sampling in the center of the river needs to be completed by boat, so sampling is more troublesome. Second, there are some telescopic Type sampling device can collect water samples in the center of the river, but this device cannot be folded, which makes it very inconvenient to carry and store. Third, for water quality sampling, most of them are to collect water quality on the surface of the water flow. However, it is not easy to accurately collect to a predetermined depth. Fourth, each water collector basically requires multiple people to coordinate work, and the sampling repeatability is high, the sampling synchronization of each layer of the water body is small, the disturbance to the water body is large, and it is difficult to collect in-situ water samples, or The sampler is not automatic enough to fully meet the needs of water stratified synchronous and efficient sampling
