River desilting water vehicle

Abstract

The invention discloses a river desilting water vehicle which comprises an above-water platform (10), an underwater platform (15) and a lifting platform (14). The middle of the lifting platform (14) is provided with a flexible impeller (13) used for scooping up riverbed silt in a penetrating mode. The four corners of the lifting platform (14) are each provided with a rotary rod (22). Fans (3) are arranged on the portions, located above the above-water platform (10), of the rotary rods (22). The two ends of a drive gear shaft (29) of the flexible impeller (13) are separately engaged with reduction gear sets (12) which are engaged with fan rotary rod gears (23) arranged on the rotary rods (22) in a sleeving mode. According to the river desilting water vehicle, riverbed bottom mud is stirred through kinetic energy of flowing water and transported to downstream ocean along with the flowing water, no secondary transport cost exists, water surface wind energy and solar energy are used as additional power, the desilting efficiency is improved, clean energy is used, and zero-carbon emission is achieved.

Description

technical field [0001] The invention relates to a river dredging water truck, which belongs to the technical field of water conservancy machinery. Background technique [0002] The main problem of the Sanmenxia Reservoir is the siltation of the Wei River. The Wei River is about 818 kilometers long, with a drainage area of ​​134,800 square kilometers and a population of about 23 million. The Guanzhong Plain, formed by the alluvial deposits of the lower reaches of the Wei, Jing, and Luo rivers, is known as Qinchuan, which is 800 miles away. It has been known as the world's largest granary since ancient times. The biggest negative impact of the Sanmenxia Reservoir is that it causes severe siltation in the lower reaches of the Weihe River, flooding and immersion of farmland on both banks, and salinization of the land, bringing high flood risks to the lower reaches of the Weihe River and the ancient capital of Xi'an. [0003] The operation mode of Sanmenxia Reservoir has gone t...

Problems solved by technology

The biggest negative impact of the Sanmenxia Reservoir is the severe siltation of the lower reaches of the Weihe River, flooding and immersion of farmland on both banks, and salinization of the land, bringing high flood risks to the lower reaches of the Weihe River and the ancient capital of Xi'an

With the further strengthening of water and soil erosion control in the Loess Plateau and the gradual improvement of the Yellow River water and sediment control system, the sediment of the Yellow River may be further reduced in the future, but the runoff capacity of the basin will also decline accordingly, and the amount of water entering the river will continue to increase. It is impossible to form a large flood to scour the river bed, and it is difficult to transport the sediment deposited in the Tongguan River for a long time to the downstream
