AI Technical Summary

Technical Problem

The existing sewage blocking devices cannot be effectively fixed in areas that are affected by waves and tide levels at sea, and cannot prevent the silt water generated by dredging and filling from spreading to other waters.

Method used

An anti-fouling curtain is designed, including a silt curtain, float and prefabricated sinker. The top edge of the mud curtain is bent and fixed to form a cylindrical cavity, and the float is inserted into the cavity. The prefabricated sinker is connected through the metal keyhole and the rope body, and the silt curtain is fixed to the bottom of the water. The counterweight iron chain pulls the silt curtain to unfold vertically, and the reinforcement belt strengthens the strength.

Benefits of technology

It effectively prevents the silt water generated by dredging and filling at sea from spreading to other waters, and at the same time improves interception efficiency, and is suitable for areas with greater impact on waves at sea.

Abstract

The present invention relates to the technical field of water-related engineering. Disclosed is an anti-fouling curtain. The anti-fouling curtain provided in embodiments of the present invention comprises: a silt curtain, a float, and prefabricated falling bodies; the top edge of the silt curtain is bent and fixed to form a cylindrical cavity, and the float is inserted into the cylindrical cavity; a plurality of metal locking holes are formed at intervals on both the front and back sides of the silt curtain along a side edge of the silt curtain; the metal locking holes located at the top of the silt curtain are all connected to the prefabricated falling bodies by means of ropes; the metal locking holes located at the bottom of the silt curtain are all connected to weighted iron chains; the float floats above the water level, the prefabricated falling bodies sink to the water bottom, and the weighted iron chains pull the silt curtain to unfold vertically; at least one reinforcing strip is arranged on the silt curtain in both horizontal and vertical directions; a plurality of metal holes are also formed in the silt curtain along the side edge of the silt curtain. According to the embodiments provided in the present invention, floating objects on the water surface can be intercepted, and the diffusion of silt water can also be prevented, thus effectively improving the interception efficiency of the anti-fouling curtain.
