Riverbed sludge down-flow self-propelled multi-section collecting device

Abstract

The invention discloses a riverbed sludge down-flow self-propelled multi-section collecting device in the technical field of riverbed governance. The device comprises a walking support, a circulation collection assembly and a driving anti-blocking assembly, wherein the middle section of the walking support is composed of a sealing pipe, and two ends of the walking support are composed of discs; a collection cavity is formed in each branch section of an inner cavity of the cross-shaped piece; and the driving anti-blocking assembly is arranged on the outer surface of the cross-shaped piece. The device is advantaged in that a driving gear ring is driven to rotate through a rotating gear, a cross-shaped piece is driven to rotate, when each supporting foot makes contact with the riverbed surface, the supporting feet rotate, meanwhile, a conical fluted disc rotates to drive a conical gear to rotate, drawing operation is conducted in an inner cavity, upward suction force is generated in a collecting cavity, then sludge is sucked into the collecting cavity, and in the collection process, the gear insertion rods are gradually pulled out outwards, and a certain length of riverbed sludge is sequentially subjected to segmented collection operation in the water flow direction, so tedious operation of placing and taking one by one is avoided, labor intensity is reduced, and collection efficiency and quality are improved.

Description

technical field [0001] The invention relates to the technical field of river bed treatment, in particular to a downstream self-propelled multi-stage collection device for river bed silt. Background technique [0002] The river bed is also called "river channel". The submerged part of a river valley. Varies with the rise and fall of the water level. Its shape is affected by topography, geology, soil, water erosion, transportation and sediment accumulation. There are two types of plain river channels and mountain river channels. In plain river channels, the channel through which the water flows in the dry season is generally called the "dry water channel", also known as the "basic channel" or "main channel"; ". Channels in mountainous areas have large gradients and rapid currents, and their shapes are generally stable in dry seasons; during flood periods, rivers often carry a large amount of moving materials, which are deposited as alluvial fans near the mouths of tributa...

Problems solved by technology

[0003] In order to detect the composition of riverbed sediments, that is, the composition of riverbed silt, it is necessary to use tools to sink into the bottom of the water to complete sampling. However, when collecting riverbed silt, it is generally necessary to collect a section of length in sections to completely analyze the composition of the riverbed. However, now Some collection devices can only work in a specific area, and need to be taken out and put in repeatedly. The collection time needs to be waited, and it cannot work without operation for a long time, which reduces the work efficiency. For this reason, We propose a downstream self-propelled multi-stage collection device for riverbed silt
