A hydrological monitoring device

Abstract

The invention discloses a hydrological monitoring device. The water sample collection bucket of the water body sampling mechanism is divided into a plurality of water sample storage chambers provided with water inlets, each water inlet is provided with a closed door; the longitudinal center of the water sample collection bucket is There is also a rotating shaft passing through each water sample storage chamber on the line, and each water sample storage chamber is provided with a driving rod fixedly connected with the rotating shaft. When the end of each driving rod is rotated to the corresponding closed door, it can just Open the closed door; the upper end of the rotating shaft protruding from the water sample collection bucket is covered with a sleeve, the lower end of the sleeve is fixed with the water sample collection bucket, the rotating shaft is connected with the axis of the flexible shaft, and the upper end of the sleeve is supported by the flexible shaft The tube is fixedly connected, the flexible shaft is connected with the indicating plate, the axis of the flexible shaft is connected with the rotating shaft of the indicating needle on the indicating plate, the indicating needle is fixed on the rotating shaft, and the indicating plate is equipped with an indicator corresponding to each closed door. sign. The invention can carry out sampling in each water body sampling layer after going deep into the water body at one time, which facilitates the hydrological monitoring, sampling and detection work.

Description

A hydrological monitoring device technical field [0001] The present invention relates to the technical field of hydrological monitoring, in particular to a hydrological monitoring device. Background technique During artificial hydrology monitoring, it is necessary to carry out water body sampling in the water layers of different depths in the monitored water area, Then, the collected water samples are detected, and the water sampling device in the prior art can only take water in one deep water layer at a time, Then, after testing, water can be taken from other depths of water layers, which cannot be done in one trip at the same time when the water samples are to be collected. Sampling in the same water layer requires multiple sampling, and the sampling layer is usually deep, so it is very troublesome. SUMMARY OF THE INVENTION The object of the present invention is to overcome the problem existing in the above-mentioned prior art, a kind of hydrological monitoring ...

Problems solved by technology

[0002] During artificial hydrological monitoring, it is necessary to perform water sampling in water layers of different depths in the monitored water area, and then detect the collected water samples. The water sampling device in the prior art can only take water in one deep water layer at a time. , and then take water in water layers of other depths after detection. It cannot be sampled in different water layers to be collected at the same time. Multiple sampling is required, and the sampling layer is usually deep. so very troublesome
