Problems solved by technology

Due to limited conditions, the sampling personnel usually complete the collection at the edge of the water body, or sink the water body through the counterweight lead ring to collect water samples, so as to avoid the suspended matter in the water disturbed by the bottle body from entering the water sampling bottle. The collector is accurate, portable, and compact. and other characteristics, but this method cannot realize the collection of deep water bodies at different locations and depths. The sampling water bodies here are often disturbed by other factors, and the reliability is poor, which seriously affects the accuracy of water quality sampling. The reliability of the monitoring results is also greatly affected. At the same time, the water collector is lowered to the water layer at a specific depth through the rope, and then the water sample is collected through the water layer at the depth, that is, the current water collector is based on the water surface. It is difficult to determine the specific depth of seawater in each sea area during the water collection process, which makes it inconvenient to operate and difficult to accurately collect seabed water samples with this type of fixed-depth water sampling device. The collection of water samples within a specified distance above the seafloor
[0004] When collecting water bodies in the prior art, the stability of the collection cannot be guaranteed, and the accurate orientation of the collection cannot be well controlled during the collection process, which is prone to water loss disturbance, low collection efficiency, and actual deviations

Abstract

The invention discloses a deep water sample sampling device used for a water conservancy reservoir. The deep water sample sampling device mainly comprises a fixed device, a sampler, a sampling device,a control device and a power supply device, wherein the fixed device is located at an internal vertical center position of the sampling device, and the fixed device comprises a fixed frame, a slidingboard, a track bar, a moving board, a water guide pipe, a water transmission channel and a spring bolt; the sampler is located at the inside of the fixed device, and the sampler comprises a water inlet, an obstructing device, a groove and an electric isolating board; left and right sides of the bottom of the sampling device are provided with limiting parts, and a water feeding device is arrangedunder the sampling device; the water feeding device comprises a hydraulic adjusting board, a protective mesh, a pushing board, a water feeding channel and a baffle; left and right sides of an externalwall of the sampling device are provided with balance weight parts, and an upper end of the sampling device is provided with a buoyancy force part. In a word, the deep water sample sampling device used for the water conservancy reservoir is simple in structure and convenient to operate, guarantees stability of an acquisition process and can sample deep water at different directions.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a deep water sample sampling device for water conservancy reservoirs. Background technique [0002] Reservoirs are generally interpreted as "hydraulic engineering structures that hold back flood water and regulate water flow, and can be used for irrigation, power generation, flood control and fish farming." It refers to artificial lakes formed by building dams at the narrow mouths of ravines or rivers . After the reservoir is completed, it can play the roles of flood control, water storage for irrigation, water supply, power generation, and fish farming. Some reservoirs are the main source of urban water supply. Therefore, the assessment and monitoring of the water quality in the reservoir through the collection of reservoir water samples is an important part of the scientific research of water environment and the protection and management of wa...
