Abstract

The invention provides a tandem type deepwater automatic depth setting water quality sample collector, and relates to the technical field of water quality samplers. The collector comprises a cylinder body with two through ends and a cylinder cover connected to the two ends of the cylinder body in an opening and closing manner; the opening and closing end of the cylinder cover is connected to an elastic tension mechanism, and the hinge end of the cylinder cover is provided with a locking mechanism; the locking mechanism is in transmission connection with the water pressure driving device, and the water pressure driving device drives the locking mechanism to unlock the cylinder cover through water pressure. Depth setting is converted into corresponding air pressure through the relation between the water depth and the water pressure, the problem that the depth cannot be controlled when a depth-setting sample is sampled at present is solved, scientificity, representativeness and accuracy of sample collection are guaranteed, and accurate data are provided for analysis and evaluation of a water body.

Description

technical field [0001] The invention relates to the technical field of water quality samplers, in particular to a series-connectable deep water automatic depth-fixed water quality sample collector. Background technique [0002] With the construction of large and medium-sized hydropower stations in the country, the number of cascade hydropower stations has continued to increase, forming various deep and large reservoirs of channel type. The main feature of this type of reservoir is that it has both the fluidity of the river and the stratification of the reservoir. The analysis and study of the physical, chemical and biological change characteristics of this deep and large river reservoir requires the collection of water samples at different water depths for monitoring and analysis. Due to the flow type of river-type reservoirs, it is currently a technical difficulty to accurately locate different water depths of the reservoir and obtain water samples at specified water depths...
