Reservoir fixed-point water-diversion layer sampling device

Abstract

The invention discloses a reservoir fixed-point water-diversion layer sampling device. The device comprises a floating body, a lifting through hole is arranged in the floating body, the lower end of the lifting through hole communicates with the outside, the outer side of the lifting through hole is provided with a toothed ring cavity, and a toothed ring is slidingly arranged in the toothed ring cavity. Eight sampling bottles are adopted and put in water at the same time, eight water layer samples can be collected at most each time with high efficiency and convenience, and the lifting motion and collection motion of the eight sampling bottles are both automatic operation without manual intervention, the collection efficiency can be greatly improved, the water depth in the collection process can be detected by a detection device, the collection positions are more accurate, and four pulling ropes are adopted for pulling to ensure the smooth and steady state of the underwater portions in the lifting motion and water sample collection processes.

Description

technical field [0001] The invention relates to the technical field of water sample collection, in particular to a sampling device for fixed-point aquifer layers of reservoirs. Background technique [0002] When conducting hydrological surveys, regular testing of water samples from different water layers in the reservoir is an important experimental method for obtaining reservoir hydrological data. Traditional water layer sampling generally uses sampling boats or sampling drones as carriers, and uses a single simple bottle for sampling , the sampling accuracy is not high, and only one layer can be collected at a time. When carrying out hydrological surveys, collecting water samples from multiple water layers requires repeated operations, which wastes manpower and material resources, and the collection efficiency is low. Contents of the invention [0003] technical problem: [0004] Traditional water sample collection can only collect one layer of water samples at a time, ...

[0002] When conducting hydrological surveys, regular testing of water samples from different water layers in the reservoir is an important experimental method to obtain hydrological data of the reservoir. Traditional water layer sampling generally uses sampling ships or sampling drones as carriers, and uses a single simple bottle for sampling , the sampling accuracy is not high, and only one layer can be collected at a time. During the hydrological investigation, it is necessary to collect water samples from multiple water layers repeatedly, which wastes manpower and material resources, and the collection efficiency is low.
