Embodiment 1

[0042] An automatic phosgene fish luring system based on a fish-collecting boat, comprising a fish-collecting boat 1; 7 is hinged with the bow, and the fish guide grid 7 is connected with the gate post 9 positioned at the bow by a wire rope 10, so that the fish guide grid 7 can be retracted.

[0043] The stern of the ship is movably connected with the fish-collecting box 3, and can be transported away by the fish-carrying boat when the fish-collecting box 3 is full. A fish passage 2 is provided in the middle of the fish-collecting boat 1, and at least one side of the fish-collecting boat 1 is connected to the river bank through an intercepting air curtain device 14, and the river is intercepted by the air curtain;

[0044] An underwater fish luring light 8 is provided at the bottom of the fish guide grid 7, and a fishway fish luring light 4 is provided at the fish passage 2;

[0045] The bow of the fishing boat 1 is provided with a bow fishing light 6 . With this structure, ...

Embodiment 2

[0055] On the basis of embodiment 1, a kind of fish luring method that adopts the automatic phosgene fish luring system based on the above-mentioned fish gathering boat may further comprise the steps:

[0056] 1. Open the intercepting air curtain device 14 to intercept the river;

[0057] 2. Turn on the bow fish lure light 6 to lure fish;

[0058] Turn on the bow fish lure light 6, the underwater fish lure light 8 and the fishway fish lure light 4 to lure fish schools into the fish passage 2;

[0059] 3. Turn off the bow fish luring light 6, the underwater fish luring light 8 and the fishway fish luring light 4 in order to make the fish enter the fish collection box 3;

[0060] The collection of fish is realized through the above steps. When the number of fish in the fish collection box is collected to a certain amount, it will be collected by boat and transferred to the shore road, and finally transported to the upstream of the dam by a fish transport vehicle for release, s...

Embodiment 3

[0062] On the basis of embodiment 1, in another optional scheme, a kind of fish luring method that adopts the above-mentioned automatic phosgene fish luring system based on the fish gathering boat may further comprise the steps:

[0063] 1. Open the intercepting air curtain device 14 to intercept the river;

[0064] 2. Turn on the bow fish lure light 6 to lure fish;

[0065] A fish finder 12 is arranged in front of the fish guide grid 7. According to the fish finder 12, the quantity of fish near the light is obtained. Lower lure fish lamp 8;

[0066] In the preferred scheme, turn on the light 13 for driving fish on the shore, and drive fish schools to move in the direction of the guide fish grid 7 .

[0067] 3. An underwater camera 11 is arranged near the fish guide fence 7 or the fish guide fence 7. The underwater camera 11 observes the number of fish. Road lure fish light 4, to lure fish into the fish passing channel 2;

[0068] Four, along the direction from the bow to ...

Abstract

The invention provides a system and a method for automatic phosgene fish attracting based on a fish collection ship. The system comprises the fish collection ship, wherein a fish guide screen is arranged on a ship bow of the fish collection ship; the ship bow is connected with a fish collection tank, a fish through passage is arranged in the middle part of the fish collection ship, at least one side of the fish collection ship is connected with a river bank through a blocking air curtain device, and a river course is blocked by an air curtain; an underwater fish attracting lamp is arranged at the bottom part of the fish guide screen, and a fish passage fish attracting lamp is arranged in the fish through passage; a ship head fish attracting lamp is arranged on the ship head of the fish collection ship. In the use process, the method comprises the following steps of opening the blocking air curtain device to block the river course; opening the ship head fish attracting lamp to attract fish schools; opening the ship head fish attracting lamp, the underwater fish attracting lamp and the fish passage fish attracting lamp to attract the fish schools to enter the fish through passage; enabling the fishes to enter the fish collection tank, so as to collect the fishes, and automatically control the whole process. The system and the method have the advantages that by adopting the scheme of combining the fish collection ship, the blocking air curtain device and the fish attracting lamp, the injury to fishes by a fish guide net in the prior art is avoided, the garage stacking is avoided, and the influence to normal navigation is avoided.

Description

technical field [0001] The invention relates to the field of fish assisted migration in ecological hydraulic engineering, in particular to an automatic phosgene fish luring system and method based on a fish collecting boat. Background technique [0002] The construction of traditional water conservancy projects has cut off the complete river while bringing great benefits to mankind. Due to physiological requirements, genetics and the influence of external environmental factors, fish often need to migrate. The dam blocks the migration channel of fish, thus causing the loss or change of fish habitat, leading to the reduction or even extinction of fish. [0003] In order to meet the needs of fish crossing dams, people have adopted fixed fish passing facilities such as fishways, fish locks, and fish elevators. On this basis, another kind of movable fish-passing facility was invented - a fish collection ship, that is, a "floating fishway". The fish container ship has the adv...
