CN-121992759-A - Graded floating object filtering device for water inlet of reservoir

Abstract

The invention discloses a hierarchical floater filtering device for a water inlet of a reservoir, which relates to the field of floater filtering of the water inlet of the reservoir, and comprises a plurality of water retaining frames, wherein the water retaining frames are fixedly connected, a water outlet groove is formed in each water retaining frame, and a multistage filtering system is constructed by sequentially installing filter screen plates with gradually reduced mesh diameters on the water retaining frames from top to bottom. When water enters the reservoir, the water firstly enters the first water retaining frame, larger floaters are intercepted by the top filter screen plate, smaller floaters enter the next water retaining frame through the water outlet groove, and the smaller floaters are filtered by the smaller-aperture filter screen plate. The grading filtering mode effectively solves the problem that a single larger-mesh filter screen cannot intercept smaller floaters, and also prevents the situation that the smaller-mesh filter screen is easy to block, so that the inflow is reduced, and water overflows to cause peripheral water and soil loss.

Description

Graded floating object filtering device for water inlet of reservoir Technical Field The invention relates to a reservoir water inlet floater filtering technology, in particular to a grading floater filtering device for a reservoir water inlet. Background In the reservoir operation management process, the filtering treatment of the floating matters at the water inlet of the reservoir is a crucial work. The water inlet of the reservoir is used as a key channel for receiving an external water source, the surrounding environment is complex, a large amount of floaters are often mixed, and the floaters are widely available and comprise but are not limited to branches, leaves, water plants and other natural impurities carried by an upstream river, and plastic bottles, foams, waste fishing gear and other garbage generated by human activities. If the floats are not effectively intercepted and cleaned, the floats can enter the reservoir along with water flow, and various negative effects are brought to the water quality, ecological environment and normal operation of the reservoir. At present, the existing reservoir water inlet floater filtering technology and device have obvious limitations. The traditional filter device mostly adopts a filter screen with single larger meshes, and the design can intercept larger floaters to a certain extent, but cannot force smaller floaters, so that a large number of fine impurities enter a reservoir to influence the water quality. Moreover, when the filter screen holes are small, although more floats can be intercepted, a blockage phenomenon is extremely liable to occur. Once the filter screen is blocked, the inflow of the water inlet can be obviously reduced, and even partial water flows overflow the water inlet to cause peripheral water and soil loss and destroy the ecological environment around the reservoir in serious cases, meanwhile, the filter screen is required to be cleaned manually and regularly in the filtering process, so that the labor intensity is high, and the cleaning efficiency is low. In the cleaning process, water inflow operation of the reservoir is often required to be suspended, and the normal operation of the reservoir is disturbed. Meanwhile, manual cleaning has a certain safety risk, and particularly under the condition of high water flow turbulence or water level, the personal safety of staff is difficult to be effectively ensured. In summary, the existing reservoir water inlet floater filtering technology and device have problems in the aspects of filtering effect, anti-blocking capability, automatic cleaning and the like, and cannot meet the actual demands of reservoir safety, stable operation and water quality guarantee. Therefore, the development of the novel reservoir water inlet floater filtering device capable of effectively solving the problems has important practical significance.
