Folding and extruding duckweed fishing and clearing device

Abstract

The invention discloses a folding and extruding type duckweed fishing and removing device, which belongs to the technical field of water body cleaning equipment. A folding and extruding duckweed fishing and removing device comprises a support frame and a salvage frame installed in front of the bottom end of the support frame. The inside of the salvage frame is equipped with a draining frame, and through the cooperating setting of the winch and the traction rope, it is easy to sink and lift up the salvage and drain mechanism, and the salvage and drain mechanism can salvage the duckweed on the water surface without manual salvage, saving labor. , the pair of extruded filter screens on the salvage and drainage mechanism can be reversely unfolded and folded towards each other. Squeeze and drain the duckweed on it to remove a large amount of water inside, effectively prevent the device from bearing a large salvage weight, and facilitate the transportation of the duckweed after salvage.

Description

technical field [0001] The invention relates to the technical field of water body cleaning equipment, in particular to a folding and extruding type duckweed fishing and removing device. Background technique [0002] Affected by industrial wastewater, domestic sewage and agricultural pollution, the eutrophication of the water body is becoming more and more serious, which will cause a large amount of duckweed to grow in the water body. When the duckweed on the water surface of a certain water area reaches a certain level, the dissolved oxygen in the water will decrease. , the water quality deteriorated rapidly. The growth and reproduction speed of duckweed is very fast, especially in water bodies such as relatively static landscape ponds, ditches and cofferdams, it will grow exponentially within a week. [0003] At present, the traditional method of cleaning duckweed in waters is mainly manual salvage net, which is labor-intensive and low cleaning efficiency; in addition, bec...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional method of cleaning duckweed in waters is mainly manual salvage net, which is labor-intensive and low cleaning efficiency; in addition, because duckweed itself is rich in water, it also automatically With more water, therefore, the salvage device bears a larger weight. If there is a large amount of water in the salvaged duckweed, it is not easy to carry, so that the overall duckweed cleaning efficiency is low.
