[0032] Embodiment: refer to Figures 1-4 The water surface foam collecting device for ship-borne culture tank shown in the figure comprises:

[0033] The bifurcated water spraying structure 1 is located at one side of the culture tank, and comprises a water supply pipe 11 in communication with the water supply system of the culture tank and two symmetrical inclined angle pipes 12, the two inclined angle pipes 12 and the water supply pipe 11 form a Y-shaped structure, and the two inclined angle pipes 12 cover the horizontal water surface of the culture tank, and the two inclined angle pipes 12 are both provided with water spraying holes 15 at the side opposite to each other, and the water spraying holes 15 spray water flow towards the middle part of the water surface of the culture tank;

[0034] The V-shaped flow guide plate 2 is located at the side of the culture tank away from the bifurcated water spraying structure 1, and the V-shaped flow guide plate 2 also covers the horizontal water surface of the culture tank;

[0035] The central collecting groove 3 is fixedly embedded in the middle part of the V-shaped flow guide plate 2 and located at the lower end of the V-shaped flow guide plate 2;

[0036] The negative pressure suction pipe 4 is fixedly connected to the bottom of the central collecting groove 3 at the upper end;

[0037] The separation tank 5 is fixedly connected to the lower end of the negative pressure suction pipe 4 at the upper end, and the separation tank 5 is provided with a gas-liquid separation mechanism.

[0038] Based on the above structure, the water spraying holes 15 on the two inclined angle pipes 12 spray the scattered water flow, the multi-angle water flow forms a fan-shaped coverage surface, the foam is driven to the central area, the foam is concentrated and then enters the V-shaped flow guide plate 2, is guided by the V-shaped flow guide plate 2 and then is concentrated in the central collecting groove 3, is then sucked into the separation tank 5 by the negative pressure suction pipe 4, and the water and the foam are separated by the gas-liquid separation mechanism in the separation tank 5, so as to realize the centralized collection and treatment of the foam dirt;

[0039] The bifurcated water spraying structure 1 forms a fan-shaped water flow layer, which can greatly increase the coverage area, meet the overall water surface coverage demand in a single breeding cabin, and obviously improve the coverage efficiency compared with the traditional single-pipe suction and the small-area coverage in the prior art, while reducing energy consumption. In addition, a hydrophobic coating can be applied on the V-shaped guide plate 2 to further improve the foam accumulation speed and accelerate the overall processing efficiency. Meanwhile, the design without mechanical agitation reduces the incidence of fish stress reaction and creates an ecological friendly foam collection and processing method.

[0040] Further, the gas-liquid separation mechanism includes a separator 51, the inlet end of the separator 51 being in communication with the negative pressure suction pipe 4, and the output end of the separator 51 being downwardly arranged;

[0049] By setting the fan-shaped water spraying hole 15, the water flow can be distributed in a fan shape, so that the water flow has a more comprehensive coverage effect, and the driving and concentrating effect of the foam is better.

[0050] Further, the V-shaped guide plate 2 is arranged downwardly close to one end of the central collecting groove 3, and the V-shaped guide plate 2 forms an angle of 20-45° with the horizontal plane, so as to facilitate the flow of water and foam along the V-shaped guide plate 2.

[0051] In order to avoid the accumulation of water flow or foam overflow, the V-shaped guide plate 2 is formed with a vertical anti-overflow plate 21 close to one end of the central collecting groove 3, so as to increase the interception volume of the V-shaped guide plate 2 and avoid the overflow of the concentrated foam to cause the decline of the collecting effect.

[0052] The working principle of the utility model is as follows: in the daily use process, the water supply system of the breeding cabin supplies water to the two inclined pipes 12 through the water supply pipe 11, the water spraying holes 15 on the two inclined pipes 12 spray water flow in a fan shape, the fan-shaped coverage area is formed by the multi-angle water flow, the foam is driven to the central area, the foam is concentrated after entering the V-shaped guide plate 2, and the foam is concentrated in the central collecting groove 3 after being guided by the V-shaped guide plate 2, and then the foam is sucked into the separation tank 5 by the negative pressure suction pipe 4, and then the foam is separated and treated in the separator 51, the foam is eliminated, the gas is discharged, and the pollutants in the foam are intercepted by the filter screen, and the filtered water is recycled by the backwater pipe 53, so as to realize the centralized collection and treatment of the foam pollutants.

[0053] The bifurcated water spraying structure 1 forms a fan-shaped water flow layer, can greatly improve the coverage area, meet the overall coverage demand of the water surface in a single breeding cabin, and obviously improve the small area coverage efficiency compared with the traditional single pipe suction and the prior art, and can also reduce the energy consumption, in addition, a hydrophobic coating can be applied on the V-shaped guide plate 2, so that the foam gathering speed is further improved, the overall processing efficiency is accelerated, and the fish stress reaction occurrence rate is reduced, and an ecological friendly foam collecting and processing mode is created.
