River hydrological sediment concentration measuring device

Abstract

The invention relates to a river hydrological sediment concentration measuring device, which comprises a base, wherein a motor with an upward output shaft and a storage battery are arranged in the base; a protective cover is arranged on the top surface of the base; a filtering device is arranged in the protective cover; the filtering device comprises a rotating shaft, a filtering part and a waterconveying part; the lower end of the rotating shaft penetrates through the top surface of the base and is connected with an output shaft of a motor through a coupler; the filtering part and the waterconveying part are connected to the rotating shaft; and the motor drives the rotating shaft to drive the filtering device to rotate. When a water sample flows onto filter paper, under the centrifugalaction generated by rotation in the rotating process of a filter screen and the filter paper, water quickly penetrates through the filter paper, silt is left on the filter paper, separation of the water and the silt is completed, the water sample can be filtered after being taken without waiting for 24 hours, the water sample filtering speed is increased, and the water sample treatment time is shortened.

Description

technical field [0001] The invention relates to the technical field of hydrological sediment concentration measurement, in particular to a river hydrological sediment concentration measurement device. Background technique [0002] River hydrology refers to the hydrological characteristics and changes in rivers, including the source of river water supply, river water regime, water temperature, ice regime, water chemistry and sediment, as well as river types, annual distribution and multi-year changes of river runoff etc. The measurement of sediment concentration is a relatively important content in hydrological observation. It mainly observes and analyzes the sediment content in river water and the classification of sediment coarse and fine particles. and bed quality. [0003] In the observation and analysis of suspended matter, after sampling the river water, it is necessary to let the obtained water sample stand still for 24 hours to remove the supernatant and then concent...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problems of too long water sample processing time, large sample weight and large space occupation in the prior art, the present invention provides a river hydrological sediment content measurement device, the purpose of which is to provide a device to speed up water sample processing to reduce The water sample processing time in hydrological observation reduces the space occupied by water samples and saves the physical strength of surveyors
