Fish sampling tool for stream environment

Abstract

The invention relates to the technical field of fish sampling, in particular to a fish sampling tool for a stream environment. The fish sampling tool comprises a box body, an adjusting mechanism is mounted at the top of the box body, a pay-off mechanism is mounted at the bottom of the adjusting mechanism, a sampling mechanism is mounted at the bottom of the pay-off mechanism, an energy supply mechanism is mounted on the box body, and a water tank is mounted at the bottom of the inner cavity of the box body; and the adjusting mechanism comprises a storage column, a servo motor, a first telescopic rod, a second telescopic rod and a fixing rod, and the storage column is connected to the top of the box body. The fish sampling tool can effectively adapt to the special stream environment for sampling, a user can conveniently sample different positions in a water area by arranging the adjusting mechanism and the pay-off mechanism, and fishes in the sampling water area can be effectively sampled by arranging the sampling mechanism. The fish sampling tool is reasonable in structural design and safe and convenient to use, saves time and labor when the sampling mechanism is folded and reduces the burden of the user.

Description

technical field [0001] The invention relates to the technical field of fish sampling, in particular to a fish sampling tool used in a stream environment. Background technique [0002] Fishermen have a wide variety of fishing methods and tools. According to the types of fishing tools, fishermen divide fishing methods into nets, bamboo tools, iron tools and other types. The fishing methods of nets mainly include silk nets, Nets, flounder nets, swirl nets, barrage nets, trawl nets, ground cages, etc., nylon wires and polyethylene wires are used to weave fishing nets with different mesh sizes and different lengths of nets. The structure of the net mainly has three layers. Nets and single-layer nets, fishermen regularly spread the wire mesh in the waters where there are fish activities, so that the fish will be entangled by the wire mesh during the activity, and then caught. [0003] When the existing fish sampling tools used in the stream environment are used, due to the specia...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a fish sampling tool for the stream environment, which overcomes the deficiencies of the prior art, has a simple structure design, and effectively solves the problem that the existing fish sampling tools cannot effectively Sampling is carried out in the special environment of the stream, and the sampling method is not good, resulting in poor fish catch effect. At the same time, the sampling process is more laborious, which increases the burden on users.
