Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the present invention will be further described:

[0027] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, a fish diversion device includes a fish receiving bin 1 and a waterway 6. The upper end of the fish receiving bin 1 is provided with a water flow nozzle 3, and the water flow nozzle 3 is connected to the nozzle fixing beam 2, and the nozzle fixing beam 2 is fixed On the upper end of the fish receiving bin 1. Preferably, the number of fixed beams 2 is greater than or equal to 2, and the number of water nozzles 3 on each fixed beam 2 is also greater than or equal to 2, so that the fish dispersal effect is better. Three of the four sides around the fish receiving bin 1 are provided with fences, and the surface without the fence is the outlet of the fish, and the bottom of the fish receiving bin 1 is located at the side without the fence to be provided with an arc-shaped groove. The lower ...

Abstract

The invention relates to a fish shoal diversion device which comprises a fish shoal receiving cabin and water channels, wherein water flow nozzles are arranged at the upper end of the fish shoal receiving cabin; fences are arranged on three of four sides of the fish shoal receiving cabin around; a side without a fence is the outlet of fishes; an arc-shaped groove is formed in the bottom of the side, without the fence, of the fish shoal receiving cabin; a base is arranged under the fish shoal receiving cabin; a rotating shaft in contact and matching with the arc-shaped groove of the fish shoalreceiving cabin is arranged at the upper end of the base; jacking telescopic rods are arranged on one side, far away from the rotating shaft, of the upper end of the base; the bottom of the fish shoalreceiving cabin is supported by upper ends of the jacking telescopic rods; and the multiple water channels are arranged on the lower side of the outlet of the fish shoal receiving cabin. By adoptingthe fish shoal diversion device, fish shoals can be conveniently separated.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a fish diversion device. Background technique [0002] In the stage of fish breeding, there will often be a large number of clusters during feeding. The gathered fish include fish of different sizes, which is not conducive to the unified feeding of fish. Big fish have a strong ability to snatch food, which will cause small fish to be unable to eat fish food and affect the growth of small fish. Moreover, when fish are sold, the mixing of large and small fish is not conducive to the price of fish sales. Therefore, people have further developed the need to divert fish schools and disperse large and small fish. For ornamental fish, not every fish of the same species has the same ornamental and sales value. The actual situation is that among a large number of ornamental fry, only a small part has high ornamental value and market value. It is necessary to separate and screen ou...
