Shift-fork-type anti-silting recharge system applied to river channel

Abstract

The invention discloses a shift-fork-type anti-silting recharge system applied to a river channel. The shift-fork-type anti-silting recharge system comprises a recharge pool and a recharge well, the recharge pool is arranged on a revetment of the river channel, the recharge well is arranged below the revetment crest, and the recharge pool communicates with the recharge well through a recharge pipeline; a water-permeable cover plate is arranged on the upper part of the recharge pool; a water collecting tank is formed in the recharge pool and rotationally provided with a driving shaft; a drivingturbine is arranged at the lower end of the driving shaft, and the upper end of the driving shaft extends out of the recharge pool; a shift fork is rotationally arranged on the water-permeable coverplate, a cam is arranged at the top end of the driving shaft, a shifting rod is slidably arranged on the cam, and the shift fork can be driven to swing back and forth in the rotating process; and water leakage holes are formed in the positions, above the driving turbine, of the water collecting tank. According to the shift-fork-type anti-silting recharge system, silting can be effectively prevented, a reversed filter is prevented from being washed away, an emergency valve can be closed when the water quality is contaminated, and groundwater is prevented from being contaminated.

Description

technical field [0001] The invention relates to a refilling system, in particular to a self-seepage and reverse filtration refilling system with anti-silting function applied to river courses. Background technique [0002] In water-short areas with uneven rainfall, the shortage of water resources seriously restricts the life and economic development of local people. In order to solve this problem, in addition to strengthening people's awareness of water conservation, how to effectively use the rainwater resources in the river is also an important measure. . [0003] At present, in order to make full use of rainwater resources, a kind of reinjection well, which has the function of filtering particles in water, is often arranged in some seasonal rivers, that is, reverse filter reinjection well. The reverse filtration recharge well currently used is composed of a recharge tank and an ordinary recharge well, wherein the recharge tank is often placed underground, and the common ...

AI Technical Summary

Problems solved by technology

[0004] 1. The recharge tank is easily blocked by river bottom silt and loses the function of reverse filtration and recharge

[0005] 2. The reverse filter material in the recharge tank is easily washed away by the water flow, reducing or losing the reverse filter function, and the water quality of the recharge water cannot be guaranteed

[0006] 3. When encountering an emergency situation of water pollution, the recharge process cannot be controlled, resulting in groundwater pollution
