Intercepting device for marine organisms of coastal power plant

According to the marine organism intercepting device for the coastal power plant, an air curtain intercepting device is arranged at a water intake, compressed air is blown into a submarine pipeline with a nozzle through an air compressor, and the compressed air is sprayed out of the nozzle to form an air curtain wall; jellyfishes near the water intake float after the umbrella part is inflated under the action of the air curtain wall, the jellyfishes cannot sink after floating on the sea surface and only can drift in the water surface flowing direction, the jellyfishes entering the harbor basin water intake can be greatly reduced, and a good effect of intercepting planktons such as the jellyfishes is achieved; classified and graded intercepting, guiding and collecting of marine creatures and marine garbage can be achieved through the multiple intercepting nets, the automatic salvage ship can salvage and transport the marine creatures in time, the situation that the intercepting nets gather a large number of ma
