Reservoir Ultra-Fine Sediment Extraction System Equipped Based on Vertical Self-adaptation

Abstract

The invention discloses a carrying device of a reservoir ultra-thin particle sediment extracting system based on vertical self-adaptation. The carrying device comprises a main floating box and lateral floating boxes arranged on the two sides of the main floating box, and the main floating box and the lateral floating boxes are of full-electric welding steel structures and are connected through detachable floating box connecting hinges. The main floating box comprises a main floating box deck and a main floating box ship bottom plate, wherein the main floating box deck and the main floating box ship bottom plate are welded together through main floating box side plates; the lateral floating boxes comprise lateral floating box decks and lateral floating box ship bottom plates, and the lateral floating box decks and the lateral floating box ship bottom plates are welded together through lateral floating box side plates. By the adoption of the floating box combination mode, the main floating box and the lateral floating boxes are of the full-electric welding steel structures, and the carrying device is reasonable in overall structure, high in safety coefficient and adaptive to sand excavation or dredging of reservoir regions and lake water areas with shallow depositing layers.

Description

technical field [0001] The invention belongs to the technical field of sand mining equipment, and mainly relates to a vertically self-adaptive reservoir ultrafine particle sand extraction system carrying device. Background technique [0002] After the completion and operation of the reservoir hub project, it has played an important role in the development of the local industrial and agricultural economy and flood control safety. Most of the reservoirs, especially the reservoirs of sandy rivers, have high sediment concentration in the flood season, and the sediment deposition in the reservoirs will be more serious, which greatly shortens the service life of the reservoirs, leads to a reduction in water storage, and seriously affects the economic development of industry and agriculture in the basin area. . [0003] Many reservoir projects do not consider sand discharge facilities in their planning and design. In order to discharge the reservoir sediment out of the reservoir, ...

AI Technical Summary

Problems solved by technology

Most of the reservoirs, especially the reservoirs of sandy rivers, have high sediment concentration in the flood season, and the sediment deposition in the reservoirs will be more serious, which greatly shortens the service life of the reservoirs, leads to a reduction in water storage, and seriously affects the economic development of industry and agriculture in the basin area.

[0003] Many reservoir projects do not consider sand discharge facilities in their planning and design. In order to discharge the reservoir sediment out of the reservoir, they have to use the reservoir diversion tunnel to discharge sand. However, the elevation of the opening and closing platform of the diversion tunnel inlet gate is generally low, and the reservoir water level must be lowered. many gates to open

Sometimes the reservoir is emptied by mechanical hauling and mechanically assisted hydraulic dredging to remove the silt in front of the dam, but the cost of cleaning the silt per cubic meter is very high and consumes a lot of precious water resources

[0004] Sand pumping platforms are commonly used sand mining or dredging equipment in rivers and lakes, but the existing sand pumping platforms have fewer functions, especially not suitable for sand mining or dredging operations in reservoir areas and lake waters with shallow sediment layers.
