Embodiment 1

[0044] An automatic phosgene fish attracting system based on a fish gathering boat, comprising a fish gathering boat 1. The bow of the fish gathering boat 1 is provided with a fish guide grid 7, and the sides and bottom of the fish guide grid 7 are equipped with fish guide nets. 7 is hinged to the bow of the ship, and the fish guide 7 is connected to the gate post 9 at the bow of the ship by a wire rope 10, so that the fish guide 7 can be retracted.

[0045] The stern of the ship is movably connected with the fish collecting box 3, and when the fish collecting box 3 is full, it can be transported away by a fish ship. The fish collecting vessel 1 is provided with a fish passage 2 in the middle, and at least one side of the fish collecting vessel 1 is connected to the river bank through an intercepting air curtain device 14, and the air curtain is used to intercept the river;

[0046] An underwater fish trapping lamp 8 is provided at the bottom of the fish guide grid 7, and a fishway...

Embodiment 2

[0057] On the basis of Embodiment 1, a fish attracting method using the above-mentioned automatic phosgene attracting fish system based on a fish gathering boat includes the following steps:

[0058] 1. Turn on the intercepting air curtain device 14 to intercept the river;

[0059] 2. Turn on the bow fishing lights 6 to lure fish;

[0060] Turn on the bow fish lure light 6, underwater fish lure light 8 and fishway fish lure light 4 to lure the fish into the fish passage 2;

[0061] 3. Turn off the bow fish lure light 6, underwater fish lure light 8 and fishway fish lure light 4 in turn to make the fish enter the fish collecting box 3;

[0062] Collect the fish through the above steps. When the number of fish in the fish collecting box reaches a certain amount, they are collected by boat and transported to the shore road, and finally transported to the upper reaches of the dam by fish trucks for release, so that the fish can safely pass the dam.

Embodiment 3

[0064] On the basis of Example 1, in another optional solution, a fish attracting method using the above-mentioned automatic phosgene attracting fish system based on a fish gathering vessel includes the following steps:

[0065] 1. Turn on the intercepting air curtain device 14 to intercept the river;

[0066] 2. Turn on the bow fishing lights 6 to lure fish;

[0067] A fish finder 12 is installed in front of the fish guide 7 to obtain the number of fish near the light according to the fish finder 12. When the set value is reached, the bow fish trap light 6 is controlled to approach the fish guide 7 and the water is gradually turned on. Lower fish trap 8;

[0068] In a preferred solution, the shore fish driving lights 13 are turned on, and the fish are driven to move in the direction of the fish grid 7.

[0069] 3. An underwater camera 11 is provided near the fish guide 7 or the fish guide 7, and the underwater camera 11 observes the number of fish. When it reaches a predetermined valu...

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 a fish attracting method based on an automatic phosgene fish attracting system based on a fish collecting vessel. Background technique [0002] The construction of traditional water conservancy projects, while bringing huge benefits to mankind, cut off a complete river. Fish often need to migrate due to their physiological requirements, genetics and the influence of external environmental factors. The dam blocks the migration channels of fish, resulting in the loss or change of fish habitat, resulting in the reduction or even extinction of fish. [0003] In order to meet the needs of fish crossing the dam, people have adopted fixed fish crossing facilities such as fish passages, fish gates, and fish lifts. On this basis, invented an activity fishing facility-a fishing vessel, or "floating fishway". The fishing vessel has the advantages of fle...
