Retaining dam device for cleaning river channel garbage

Abstract

The invention discloses a retaining dam device for cleaning river channel garbage, and relates to the technical field of dams. The water retaining dam device for cleaning the river channel garbage comprises an external water retaining mechanism used for externally intercepting the garbage, an air bag extrusion mechanism used for extruding an air bag, a collision vibration mechanism used for generating vibration through collision, an extrusion opening mechanism used for extrusion opening and an elastic cutting mechanism used for elastic cutting. A supporting plate is arranged in the external water retaining mechanism, and the air bag extrusion mechanism is arranged in the external water retaining mechanism through the arranged supporting plate. According to the retaining dam device for cleaning the river channel garbage, after a filter screen is blocked, water pressure on the filter screen is increased through water flow, so that the filter screen is inclined, and after the garbage is removed, the filter screen can reset under the action of a spring, so the situation that the garbage is automatically treated is ensured; and the filter screen extrudes a first air bag, and s first air bag on the other side protrudes, so the garbage is prevented from being clamped into a crack between the supporting plate and the filter screen.

Description

technical field [0001] The invention relates to the technical field of dams, in particular to a dam device for cleaning river waste. Background technique [0002] A dam is a water-retaining structure that intercepts the water flow of a river channel to raise the water level or regulate the flow. It can form a reservoir, raise the water level, adjust the runoff, and concentrate the water head. It is used for flood control, water supply, irrigation, hydroelectric power generation, and improved shipping. Dam Connected to multiple rivers whose water eventually flows to a dam. [0003] There are often a lot of garbage floating in the river, and the garbage eventually follows the river to the dam, causing environmental pollution. It is necessary to set up a dam at the end of the river to intercept the garbage, but the excessive storage of garbage often affects the filtering effect of the dam. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the pr...
