Intelligent lifting intercepting device for medium and small river channels

Abstract

The invention discloses an intelligent lifting intercepting device for medium and small river channels. The intelligent lifting intercepting device comprises supports fixed to the two sides of the riverway, lifting rods are arranged on the supports correspondingly, a rotating shaft is erected between two lifting frames, a plurality of intercepting nets are arranged in the circumferential directionof the rotating shaft, and the intercepting nets are installed on the rotating shaft through an outer frame and are in a tensioned state; a liquid level meter is arranged in the riverway, and the liquid level meter is linked with a motor through a liquid level sensor and an electric cabinet to drive the lifting frames and the intercepting nets to ascend and descend. According to the intelligent lifting intercepting device for the medium and small rivers, the height of the intercepting net can be automatically adjusted according to the water level of the rivers, so that the height of the intercepting net is always matched with the water level of the river channels, and floating garbage in the rivers is intercepted timely and efficiently; when the rotating shaft rotates, the intercepting nets have the functions of intercepting garbage and collecting the garbage; and nozzles arranged on the outer frame can effectively flush blockages in meshes of the intercepting nets, loss of the intercepting nets is reduced, and the service life of the intercepting nets is prolonged.

Description

technical field [0001] The invention relates to ecological environmental protection technology, in particular to an intelligent lifting and intercepting device for medium and small rivers. Background technique [0002] Due to the economic development, the river has been very seriously polluted, often floating garbage from the living quarters. These garbage are easy to accumulate in the river, if not cleaned or intercepted in time, it will cause new pollution to the downstream water quality, affect the water quality, and pose a threat to the water surface landscape, water supply, aquatic products, shipping industry, hydropower hub, etc. [0003] Most of the existing methods of cleaning river rubbish are intercepted by the intercepting net. The upper part of the intercepting net is provided with floating objects, and the lower part is provided with counterweights. The counterweights fix the position of the intercepting net in the river, and the floating objects will pull the i...

AI Technical Summary

Problems solved by technology

The problem with this setting is that when the water level rises a lot, if the buoyancy of the floating object is less than the gravity of the counterweight, the interception net will not be able to intercept if it is submerged under the water surface. If the buoyancy of the floating object is greater than the gravity of the counterweight , the position of the intercepting net in the river cannot be fixed; and when the water level drops a lot, the intercepting nets are piled up together, and still cannot intercept
