In-situ automatic collection device and method for sand-laden water body of shallow water

Abstract

The invention discloses an in-situ automatic collection device for a sand-laden water body of shallow water. The device comprises a triangular bracket, an angle controller, a water inlet control panel, a fixed rod and a control system, wherein the lower end of the fixed rod is connected with a tubular water sampler through a rotary fixed seat; the water sampler is provided with four attitude control wings, and a motor and a flow baffle are arranged in the water sampler; the water sampler is connected with a bleeder hole in the water inlet control panel through a communicating pipe arranged in the fixed rod; a through hole is formed in the middle of the water inlet control panel; an irrotational fixed hole is formed in the lower half part of the through hole; and a rotatable fixed hole is formed in the upper half part of the through hole; and a vacuum flask fixing tray is arranged at the upper part of the water inlet control panel through a rotating shaft in the rotatable fixed hole. The in-situ automatic collection device is simple in structure and convenient to operate, the water collection direction can be controlled, sampling along the ocean current direction is achieved, the in-situ automatic collection device is suitable for in-situ automatic collection of the sand-laden water body of the shallow water, and the in-situ automatic collection device and method have the advantages of being accurate in sampling depth, convenient, fast and high in automatic degree in comparison with traditional water sample collection device and method.

Description

technical field [0001] The invention relates to an in-situ automatic collection device and method for sand-containing water in shallow sea areas, which is used for in-situ, continuous and automatic sampling of sand-containing water related to marine suspended sediment and marine deposition dynamics under normal sea conditions or storms in shallow sea areas. Background technique [0002] Marine environmental pollution monitoring, marine hydrological observation, marine chemistry, geological survey, and sediment resuspension process research all require on-site collection of water samples of a certain volume under certain conditions, and then carry out experimental analysis on board or in the laboratory through corresponding equipment . [0003] According to different research purposes, the water collectors, water collection methods, and water collection requirements used in collecting seawater samples are quite different. At present, the types of water collectors mainly incl...

Problems solved by technology

This traditional sampling method has a large workload, high cost, long time, and consumes a lot of manpower and material resources.

When there is a large flow rate in the water body, especially when studying storm deposition, the water collector often deviates from the predetermined sampling point, and the sampling depth will also deviate, and the sampling results are greatly affected by human factors

In addition, using boats and manpower to sample seawater in a tidal cycle in the study area in stormy weather has a high risk
