A linkage protective blocking device for flood discharge pipelines used in water conservancy projects

Abstract

The invention provides a linkage type protective intercepting device for flood discharge pipelines of water conservancy projects, which relates to the field of environmental protection devices, and solves the problem that the temporary collection of sundries cannot be realized in linkage while scraping, which is often done manually after scraping. Clean up the debris on the scraper arm; the intermittent collection of debris cannot be realized through the linkage structure, and the collection door is normally open, which is prone to the problem of the collected debris being washed out by water again. A linkage protection blocking device for flood discharge pipelines of water conservancy projects, comprising a cement installation main body, a rotating shaft A and a rotating shaft B; a pipeline is installed on the cement installation main body, and a cleaning structure is also installed in the cement installation main body. Because a toggle lever is installed on the rotating shaft A, and when the toggle lever is in contact with the connecting bar, and when the toggle lever rotates with the rotating shaft A, the connecting bar is in a state of continuous extrusion and bending, thereby realizing the continuous opening of the baffle, In turn, the continuous collection of garbage is realized.

Description

technical field [0001] The invention belongs to the technical field of environmental protection devices, and more specifically relates to a linkage protection blocking device for flood discharge pipelines of water conservancy projects. Background technique [0002] Flood drainage pipes are easy to be blocked, affecting normal drainage. For example, domestic garbage flows into urban underground drainage pipes and blocks pipes. [0003] For example, the application number: CN201910980441.5, the invention discloses an anti-blocking device for drainage pipes, which includes a housing arranged obliquely upwards, a spiral push rod and a head arranged in the housing, and a spiral blade is provided at the bottom of the spiral push rod. The length of the helical blade is two-thirds of the length of the helical push rod. A water inlet is provided on the top of the housing near the bottom, and the water inlet is set towards the propulsion direction of the helical blade. A filter scree...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a linkage protection blocking device for flood discharge pipelines of water conservancy projects to solve the problem that the existing devices do not It is possible to realize the temporary collection of debris while scraping, but the debris on the scraping arm is often cleaned manually after scraping, which is poor in practicability; moreover, the existing devices cannot realize the collection of debris through the linkage structure. Intermittent collection of objects, and the collection door is normally open, which is prone to the problem of the collected debris being washed out by water again
