Segmentation and split type trash rack

Technical Field

The utility model relates to a sea water filth processing technology field specifically is a segmentation and split type trash rack.

Background

The most common method for intercepting seawater fish, shrimp and sewage at present is a sewage blocking net. The trash rack is soaked in the sea to intercept marine organisms, but the size and impact force of sea waves are unpredictable and unstable, when large sea wind and sea waves are encountered, the sea waves impact the trash rack greatly, and if a large amount of marine organisms are intercepted on the trash rack, the trash rack is impacted by the sea waves, so that the trash rack can be damaged; particularly, the trash rack is more destructive to sudden large sea waves. The trash rack can be damaged by the impact of large waves on the trash rack for a long time. When the trash blocking net intercepts a certain amount of dirt, a diver needs to clean the trash blocking net underwater, the safety risk is high, the net needs to be replaced, the whole net needs to be replaced completely, manpower and material resources need to be consumed, the ship passing through the sea surface is influenced by the fact that the common pocket net floats on the water surface, the pocket net can grow rapidly under the irradiation of sunlight, and the difficulty in cleaning the net is increased.
