River sewage sampler

Abstract

The invention discloses a riverway sewage sampler which comprises a central shaft. A counter weight body of which the outer diameter is greater than that of the central shaft is welded at the bottom of the central shaft; four surfaces of the central shaft are vertically welded with supporting plates; one or above of fixed shaft sleeve is welded at equal intervals on the lower end face of each supporting plate; a sampling ball is filled at the bottom of each fixed shaft sleeve; a protrusion is formed at the top of each sampling ball; each protrusion is disposed in a fixed hole formed on the lower end face of the corresponding fixed shaft sleeve. When the riverway sewage sampler is in use, each sampling ball is in a wizened state, the sampling balls are randomly thrown into a riverway and positions of the sampling balls are continuously changed along with riverway water, so that the riverway water at different positions can be absorbed one by one, thereby implementing sampling on the riverway water at different positions; sampling at the random position can be implemented without any electronic equipment.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a river channel sewage sampler. Background technique [0002] River water needs to be regularly sampled and tested. The river water sampler is commonly used for sampling. The structure of the traditional river water sampler is relatively simple, and it can only be sampled at a fixed point, and the composition of the river water in different locations and areas is very large. Different, so we often need to sample multiple fixed-point locations, and carry out comprehensive detection and sampling of river water, but this requires the staff to move to different points for individual sampling, which is very inconvenient, and the labor intensity of the staff is high. River water sampling in different locations, so there are many deficiencies in the traditional sampler. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide...
