specific Embodiment approach 1

[0009] Specific implementation mode one: combine figure 1 with figure 2 Illustrate, a kind of simulation experiment device that utilizes fish finder to detect living fish of the present embodiment, described simulation experiment device comprises peripheral net cage 1, cover plate 2, puts in net cage 3, live fish reclaims net cage 4, puts in net Box moving mechanism 5 and fish finder 6;

[0010] Peripheral net cage 1, put in net cage 3 and the profile of live fish recovery net cage 4 are cuboids, and the four side walls and the bottom surface of peripheral net cage 1, throw in net cage 3 and live fish recovery net cage 4 are net faces respectively, The upper ends of peripheral net cage 1, throwing net cage 3 and live fish recovery net cage 4 are open ends, and cover plate 2 covers are contained on the open end of peripheral net cage 1, and the two are detachably connected, and cover plate 2 Be provided with live fish drop-in port 7 and live fish recovery net cage mouth 8, p...

specific Embodiment approach 2

[0011] Specific implementation mode two: combination figure 1 with figure 2 Illustrate, the simulated experiment device described in the present embodiment also comprises support plate 12, and described throwing net cage moving mechanism 5 comprises rotating bar, sealed bearing 13, axle sleeve 14, fixed pin 15, shaft retaining ring 17, two driving nuts 18 and two connecting posts 19; the rotating rod comprises a polished rod 20 and a leading screw 21, one end of the polished rod 20 is affixed to an end of the leading screw 21, and the side corresponding to the live fish outlet 9 on the throwing net 3 is fixedly connected with a support plate 12. The outer surface of the support plate 12 has two connecting columns 19 fixed up and down side by side, two driving nuts 18 are arranged side by side up and down, and the two driving nuts 18 are arranged in one-to-one correspondence with the two connecting columns 19, and each driving nut 18 The outer wall is affixed to the end of th...

specific Embodiment approach 3

[0013] Specific implementation mode three: combination figure 1 with 2 Illustrate, the profile of the live fish inlet 10 of the live fish recycling net cage 4 of the present embodiment is a square truss shape, and the small port 22 of the square truss shape live fish inlet is adjacent to the net cage 3 and is set. Design like this, because live fish enters the mouth 10 and is the form of shutting up, is convenient to live fish income in the net cage 4 of live fish recovery. Other components and connections are the same as those in the first embodiment.

Abstract

The invention discloses a simulation experiment device for detecting live fishes by using a fish detector, and relates to an experiment device for detecting live fishes by using a hydroacoustic technology. The invention aims to solve the problem that a hydroacoustic live fish detection experiment device for simulating natural conditions such as field rivers, lakes and the like is absent at present. A cover plate covers an open end of a peripheral net cage; a release net cage and a live fish recovery net cage are arranged in the peripheral net cage; the release net cage is driven by a release net cage moving mechanism to move up and down in the peripheral net cage; the direction of a live fish outlet on the release net cage is opposite to the water flow direction; the side face of the livefish recovery net cage, which is opposite to the live fish outlet of the release net cage, is provided with a live fish inlet; the outer edge of the live fish recovery net cage is arranged on the cover plate; the fish detector is fixedly arranged in a mounting hole; and the mounting hole is positioned between the live fish outlet of the release net cage and the live fish inlet of the live fish recovery net cage. The simulation experiment device is used for performing detection experiments on the live fishes.

Description

technical field [0001] The invention relates to an experimental device for detecting live fish by using hydroacoustic technology. Background technique [0002] To use hydroacoustic technology to detect fish resources in rivers and lakes, it is generally necessary to carry out hydroacoustic signal discrimination experiments of fish size and species under artificial control conditions in advance, and use this as standard data to compare fish detected in wild rivers and lakes. Accurate and objective research results can be obtained by using hydroacoustic signals. Because this kind of experiment needs to be carried out in natural rivers and lakes under the wild environment, and what the fish used for experiment needs is live body. In order to meet the above experimental requirements, relevant experimental devices must be available to realize this kind of simulation experiment. At present, there is no experimental device capable of carrying out relevant scientific research. C...
