TECHNICAL FIELD
[0001] The utility model relates to water conservancy technology field especially relates to a river surface trash intercepting device for water conservancy projects. BACKGROUND
[0002] In the operation and management of water conservancy projects, effective treatment of river surface garbage is an important link to protect the ecological environment of the river and the normal operation of water conservancy facilities. With the rapid development of social economy, various types of waste generated by industrial production, urban life and other activities, as well as the seasonal growth and withering of aquatic plants in the natural environment, floating garbage often appears in the river. These garbage covers a variety of types such as plastic sundries, dry branches and leaves, and aquatic plant residues. If these floating objects randomly drift in the river, not only will it affect the overall landscape of the river, but also may pollute the water quality, interfere with the living environment of aquatic organisms, and also pose a potential threat to the safe operation of facilities such as gates and generator sets in water conservancy projects. To deal with this problem, river surface trash intercepting devices are usually used in water conservancy practice to intercept floating garbage.
[0003] The river surface trash intercepting device commonly used in water conservancy projects usually includes an intercepting main body, a support frame and a fixing system. The intercepting main body is usually a trash screen or a high-strength trash screen with a certain aperture and toughness to meet the interception needs of different types of garbage. The support frame is usually made of metal or corrosion-resistant material to maintain the shape and stability of the intercepting main body. The fixing system uses anchor, pile and other components to fix the device on both sides of the river or the river bottom. Its working principle is to form a horizontal barrier on the river surface by using the intercepting main body. When the water flow moves the floating garbage to the device, the intercepting main body will block the garbage from drifting further by its structure, and the garbage will be gathered in the intercepting area by the natural impact of the water flow, so that it can be cleaned up by artificial or mechanical means, thereby realizing effective interception and control of river surface garbage.
