Embodiment 1

[0030] see also Figure 1- Figure 4 As shown, the present invention is a water quality testing and sampling device for mixed culture of shrimps and crabs in rice fields, which includes a sampling box 1, which is arranged for the convenience of water storage. A water intake hole 11 is arranged right above the sampling box 1 for the convenience of water intake. A plurality of anchor ropes 12 are fixedly connected to the side wall of the sampling box 1, which is arranged for the convenience of stabilizing the device. One end of each anchor rope 12 far from the sampling box 1 is fixedly connected with an anchor ball 13. The purpose of this arrangement is to facilitate the fixing of the device. The bottom outer wall of the sampling box 1 is provided with a sampling tube 14 in communication with the central axis. The purpose of this arrangement is to facilitate sampling. The end of the sampling tube 14 far away from the sampling box 1 is arranged in an inverted cone shape, so as to facil...

Abstract

The invention discloses a rice field shrimp and crab polyculture water quality detection sampling device which comprises a sampling box, and a water taking hole is formed right above the sampling box. According to the water quality detection and sampling device for shrimp and crab polyculture in the rice field, when water needs to be sampled, an electric telescopic rod is started, an auxiliary plate can be driven to move up and down by starting the electric telescopic rod, and an extrusion ball can move up and down under the action of an auxiliary connecting rod by moving the auxiliary plate up and down; under the action of impact force, an anti-blocking ball can transversely swing under the action of an inclined swing rod, so that a water inlet hole is exposed, external water can enter a sampling pipe, after completion, an electric telescopic rod drives an extrusion ball to move upwards, and in the upward moving process, water in the sampling pipe is pushed to enter a sampling box, so that the sampling box is used for sampling water. A worker can take water from the water taking hole so as to achieve the purpose of water quality sampling.

Description

Technical field [0001] The invention relates to the technical field of water quality detection and sampling, in particular to a water quality detection and sampling device for shrimp and crab polyculture in rice fields. technical background [0002] With the continuous development of aquaculture technology, crayfish and crabs are no longer farmed in ponds alone, which opens up a mixed breeding mode of crayfish and crabs in rice fields, which can make full use of water resources and greatly improve farmers' economic benefits. In order to improve a good growth environment for shrimps and crabs, it is necessary to ensure the quality of water quality, so it is necessary to test and sample the water quality to know the changes of water quality in time. [0003] When the existing water quality testing sampling device samples water, it is easy for the samples to mix and cross, thus affecting the accuracy of the samples. Inventive content [0004] To solve the above technical problems, ...
