Water quality detection and sampling device for shrimp and crab polyculture in park paddy field

Abstract

The invention discloses a water quality detection and sampling device for shrimp and crab polyculture in a park paddy field. The water quality detection and sampling device comprises a water quality sampling barrel, wherein a plurality of separation plates are arranged in the water quality sampling barrel; side edges of the separation plates are fixedly connected with an inner side wall of the water quality sampling barrel in a sealing manner; the separation plates are used for dividing the inner part of the water quality sampling barrel into a plurality of water quality sampling rooms; waterdischarging end openings are formed in side walls of the bottoms of the water quality sampling rooms; side edge of water blocking plates are connected with inner side walls of water inlet channels ina manner of sliding leftward and rightward; stopping rings are arranged at the right sides of the blocking plates; the left end faces of the blocking plates are fixedly connected with pushing and pressing rods which penetrate through the water inlet channels; baffle plates are arranged at penetrating-out ends of the pushing and pressing rods; the baffle plates are connected with the side walls ofthe water inlet channels through pressure springs; the elastic coefficients of the pressure springs in the water quality sampling rooms are gradually increased from top to bottom. The device is simple in structure and water quality with different depths can be automatically sampled, without the need of operation; the device is convenient to operate, can be used for sampling the water quality andslurry at the same time so as to improve the detection comprehensiveness and has relatively strong practicability.

Description

technical field [0001] The invention relates to the technical field of water quality sampling, in particular to a water quality detection and sampling device for shrimp and crab polyculture in rice fields in industrial parks. Background technique [0002] With the rapid development of social economy, the problem of environmental pollution is becoming more and more prominent, especially the problem of water environment pollution is showing the trend of regional expansion, pollution diversification and serious degree. In the face of global environmental problems and the increasingly severe water crisis, water resource protection has become an urgent problem facing human beings. In order to strengthen the monitoring of water environment quality, grasp the current situation of water quality in a timely manner, determine the temporal and spatial distribution of pollutants in the water body, and then trace the source of pollutants, pollution channels and their impact on the shrimp...

Problems solved by technology

Traditional water quality samplers also have many inconveniences and problems in the normal water quality sampling process. For example, sampling requires manual suction of water, which is troublesome, and water stains of different depths require multiple water extractions.
