Embodiment Construction

[0037] The telescopic dredging system based on the spiral operation method provided by the present invention is mainly composed of a gear-driven rotating disc coordinated with a hydraulically driven hydraulic arm and a hydraulic control mechanism. The length of the dredging arm and the angle between the dredging arm and the plane of the ship's bottom are adjusted, so that the reamer moves along the helical trajectory, constantly changing the radius of the dredging operation, and finally realizes the circular area dredging operation.

[0038] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the present invention is not limited.

[0039] The retractable dredging system based on the spiral operation mode provided by the present invention (which can be referred to as the dredging system) has a structure as follows: Figure 3-Figure 7 As shown, its position on the ship is as follows Figure 12 , Figure 13 As...

Abstract

The invention discloses a retractable mud dredging system based on a spiral working manner. The system is mainly composed of a rotary mechanism which is arranged on a ship body, close to a ship bottom part, of a midship position, and is used for providing power for rotating a mud digging arm, a hydraulic regulation and control mechanism which is used for regulating and controlling a working state of the mud digging arm, and a reamer mechanism mounted at a tail end of the mud digging arm. A circular disc rotates to drive the mud digging arm to rotate, and the length of the mud digging arm and an angle between the mud digging arm and a plane of a ship bottom base are regulated through utilizing a hydraulic system, so that a reamer moves along a spiral line track; and a mud digging working radius is continuously changed, and the mud digging work of a round surface region is finally realized. Based on the realization of the functions, the design can enlarge the area of single-time working of a mud digging ship, and frequent movement of a ship body of the mud digging ship is reduced, so that the power consumption is reduced and the mud digging efficiency is improved.

Description

technical field [0001] The invention relates to a dredging device, in particular to a scalable dredging system based on a spiral operation mode which improves dredging efficiency and reduces dredging efficiency at the same time. Background technique [0002] A dredger is a kind of engineering ship that digs out sediments such as underwater sediments. It is widely used in the construction and maintenance of large ports, land reclamation, and channel dredging. The report of the 18th National Congress of the Communist Party of China proposed the strategy of building a "marine power" for the first time, and put forward new requirements for the development of marine resources and the protection of marine rights and interests. In 2015, the State Council issued "Made in China 2025", which set "offshore engineering equipment and high-tech ships" as a key development field in the next ten years, and clearly pointed out that the country will vigorously develop resource development and...
