Underwater dredging head in type of twisting flying rope

Abstract

This invention relates to an underwater dredging head of rope cutter suction including: a flywheel, a drive rod, a rope, a breakwater and a mud-suction orifice, in which said rope passes through the edge of the flywheel, said mud-suction orifice is set on the frame of a suction pipeline of a dredge ship or its device, said drive rod is set on the suction pipeline of the suction orifice or the ship, said flywheel is set on the drive rod, which rotates to drive the flywheel to rotate, which drives the rope to rotate to cut submud underwater to strike out large and hard sundries and reduce soaked volume of them and jam of the orifice and mud cut by the rope forms mud water to enter into the mud-absorption pipeline via the orifice under the suction of the ship and a mud pump.

Description

technical field [0001] The invention relates to a device in the technical field of water conservancy engineering, in particular to a flying rope cutter suction underwater dredging head used on a dredging ship or dredging machine. Background technique [0002] More than 60% of the world's population lives less than 100 kilometers from open water; 13 of the 19 cities with a population of more than one million are built in coastal waters. With the world population projected to grow to between 8 and 10 billion by 2050, waterborne transport will continue to grow, and so the infrastructure must adapt. The pressure of overpopulation, industrial growth and the need for environmental protection will further push man to curb rivers and conquer lands to the sea. The siltation of reservoirs, ponds, and rivers in my country is becoming more and more serious, which not only directly reduces the benefits of hydropower generation, hinders ship navigation, reduces water storage resources, b...

AI Technical Summary

Problems solved by technology

In foreign countries, the current cutter suction dredging heads also use knife cutting or toothed cutting knives, which are very expensive

The main disadvantages of the vibrating dredging head of this invention are: 1) the soil sucked into the pipeline is often large in size, so that the long-distance transport of the silt will cause a large head loss along the way, and it is prone to pipeline blockage, high energy consumption, and long-distance silt transportation. Conveying is often difficult to implement; 2) The cutting knife needs to use special materials due to wear resistance, and the equipment cost is high; 3) The vibration device plus the cutting knife device has a large size and high power; 4) There is no water retaining device, and the pulp concentration is low
