Riverway water flow quality detecting and sampling device for water conservancy project

Abstract

The invention discloses a riverway water flow quality detecting and sampling device for a water conservancy project. The riverway water flow quality detecting and sampling device comprises a slide rail, a sample collection box and a sampling pipe support, wherein the slide rail is erected on a river channel, the sample collection box and the sampling pipe support slide on the slide rail; and a slide box body is slidably mounted in the middle of the slide rail. According to the riverway water flow quality detecting and sampling device for the water conservancy project, in order to prevent sundries such as aquatic plants in a riverway from interfering with the sampling process during each time of sampling work, the sundries such as the aquatic plants near a sampling opening are pushed aside by a push-away device, and the situation that the sampling process is affected due to the fact that the aquatic plants are wound on a sampling pipe is avoided; the device is provided with a plurality of sample test tubes, sampling of multiple positions can be completed at a time, and after sampling is completed, the sample collection box is moved to the shore through a first electric push rod, so that the samples are recycled in a unified mode. After the water quality sampling device is adopted, a person does not need to enter a water body for sampling, so that sampling is convenient and rapid, and safety is high; and meanwhile, the water quality sampling device is simple in structure and easy to operate and control.

Description

technical field [0001] The invention relates to the technical field of water quality sampling and testing equipment, in particular to a river channel water flow quality testing and sampling equipment for water conservancy projects. Background technique [0002] Water quality testing is a must-have project in environmental impact assessment of engineering construction, water resource development and utilization, water environment treatment projects, and water environment-related scientific research. Through water quality testing, the types and concentrations of substances contained in the target water body can be confirmed, thereby Carry out the analysis of the current situation of the water environment and the analysis of the impact of engineering construction or the study of the law of pollutant migration and transformation. In the case that the testing conditions such as equipment and personnel are available, it is first necessary to obtain a water quality testing sample o...

Problems solved by technology

[0003] In the prior art, water quality sampling is generally carried out on fixed stations or relatively large rivers or lakes. It can be carried out on a set section through a hydrological observation cableway or an observation ship, and the sampling pipe is extended into the water surface. Due to the complex situation under the water surface, water plants and other debris can easily interfere with the sampling process; when sampling multiple times, the sampling tube needs to be extended into the water surface multiple times, and the sampled water quality is filled into the collection bottle after sampling. The steps are cumbersome and the sampling efficiency is not good. High; when conducting surveys on small rivers or lakes, there is no cableway and it is not convenient to use observation ships. It is often necessary for observers to enter the water body for sampling. Water can be inconvenient and dangerous
