River water sampling device at different water depths

Abstract

The invention discloses a river water sampling device at different water depths. The river water sampling device comprises a transverse plate and a sampling barrel, wherein a vertical spiral shaft isarranged on the transverse plate; a movable sleeve which is connected with the spiral shaft in a threaded fit mode is arranged on the spiral shaft; the outer side wall of the movable sleeve is connected and fixed with a fixed sleeve arranged on the outer side wall of a supporting lifting tube through a fixed connecting rod; the sampling barrel comprises an inner barrel and an outer barrel; a rotary shaft is arranged inside the supporting lifting tube; the bottom end of the rotary shaft passes through the top wall of the outer barrel and is fixedly connected with the top wall of the inner barrel; a plurality of partitions which are parallel are arranged on the inner part of the inner barrel for dividing the inner barrel into a plurality of sampling cavities; a first water inlet is formed inthe side wall of each sampling cavity; a plurality of second water inlets which are in one-to-one correspondence to the first water inlets are formed in the side wall of the outer barrel; and a rotary rod is further arranged at the top end of the rotary shaft. The river water sampling device is simple in structure, is relatively high in reliability of sampled river water, is simple, convenient and quick to operate, can sample river water at different depths, and is relatively high in practicability.

Description

technical field [0001] The invention relates to a chemical sampling device, in particular to a river water sampling device with different water depths. Background technique [0002] For riverside chemical plants, many of the water resources used by chemical plants come from river water, and the water quality of the river water greatly affects the quality of chemical production products and increases the cost of chemical water filtration, so it is necessary to treat the river water before using it. Memory testing, knowing the water quality of the river to formulate the process of changing the water quality, and the general river water sampling device can only sample one depth of the river water at a time, and the detection requires multiple comprehensive sampling tests, so the general river water sampling device requires multiple sampling , the efficiency is low, and the deeper water in the sampling process is likely to be affected by the upper water flow, which leads to the ...
