Water conservancy and hydrological surveying and sampling method

Abstract

The invention discloses a water conservancy and hydrology surveying and sampling method. The method is characterized by comprising the following steps: step a, a surveying and sampling device is designed; b, before surveying and sampling,a base is vertically arranged in water of a river channel, and a plurality of groups of sampling boxes are vertically arranged side by side; c, during surveying and sampling, when the water level rises due to external rainstorm, the floating frame slides upwards along the sliding rails under the action of buoyancy, the whole water guiding assembly is pushed upwards through the floating frame, the sliding plate of the water guiding assembly slides upwards along the front sliding rail, and after the water level rises to the position of a set of sampling boxes close to the water surface, the sealing assembly is jacked open when the water guide assembly ascends to reach the sampling hole, the water guide assembly is communicated with the sampling hole, and water at the position is poured into the sampling box through the sampling hole; and step d, after the water level falls off, all the sampling boxes are taken down integrally, so that hydrological samples corresponding to different water level heights can be obtained.

Description

technical field [0001] The invention relates to the field of hydrology and water resources, in particular to a water conservancy and hydrology survey sampling method. Background technique [0002] In recent years, the domestic hydrological situation has been deteriorating day by day, the pollution of water resources has become increasingly serious, and the water consumption has gradually dried up. The survey of hydrology and water resources plays an important role in the protection of water resources. The sampling survey of water resources can be used to study the material composition of water in different periods, so as to facilitate the monitoring of water resources and the environment by hydrological resource managers. [0003] The applicant found that there are at least the following technical problems in the prior art: the water resource survey process requires staff to perform water sampling and analysis when the water level exceeds the previous highest position, and t...

AI Technical Summary

Problems solved by technology

[0003] The applicant found that there are at least the following technical problems in the prior art: the water resource survey process requires staff to perform water sampling and analysis when the water level exceeds the previous highest position, and the existing survey equipment requires staff to manually operate the sampling equipment. When the water level soars, it is difficult for personnel to reach the sampling area, the survey equipment is not convenient to use, and the safety guarantee ability for personnel is poor. It is impossible to retain water samples during the period when the water level rises to different heights, and it is impossible to record the highest water level data.
