Full-electric drive self-propelled trailing suction hopper dredger with dredging and measuring integrated system

Abstract

The invention provides a full-electric drive self-propelled trailing suction hopper dredger with a dredging and measuring integrated system. The full-electric drive self-propelled trailing suction hopper dredger with the dredging and measuring integrated system comprises a dredger body and is characterized in that a stern mooring area, a poop, a quarter deck chamber, a mud cabin coaming, a forecastle and a bow mooring area are sequentially arranged on a main deck of the dredger body from a stern to a bow, and a steering engine room, a propulsion motor room, an engine room, a mud cabin, buoyancy cabins located on the two sides of the mud cabin, a pump cabin, a motor room, an electrical equipment room and a fore peak are sequentially arranged below the main deck of the dredger body from thestern to the bow. According to the full-electric drive self-propelled trailing suction hopper dredger with the dredging and measuring integrated system, the self-propelled trailing suction hopper dredger adopts a full-electric driving form, and can flexibly perform power distribution of a power device under different environmental conditions, different operating conditions and different index ranges. The dredging and measuring integrated system is arranged, so that the dredger has the dredging and measuring capacity at the same time, configuration of a measuring ship is reduced, the measuringwork before dredging, during dredging and after dredging is achieved by means of the characteristic that the ship is high in maneuverability, and the dredging and measuring integrated working mode isachieved.

Description

technical field [0001] The invention relates to a self-propelled trailing suction dredger, which belongs to the technical field of dredger equipment. Background technique [0002] Self-propelled trailing suction dredger is a kind of self-propelled and loaded dredger equipped with rake head excavation equipment and hydraulic dredging device. At present, the similar self-propelled trailing suction dredgers in China have the following status: [0003] (1) The composite drive method is generally adopted, and the propulsion main engine has multiple belts. The propulsion diesel engine not only directly drives the main propeller, but also drives the shaft generator. The mud pump is directly driven by the front end of the main engine or driven by a variable frequency motor. For various working environment conditions and complex working conditions, the flexibility of the power distribution of the power plant is not high enough. Under certain working conditions, the main engine is in ...

Problems solved by technology

For various working environment conditions and complex working conditions, the flexibility of the power distribution of the power plant is not high enough. Under certain working conditions, the main engine is in a relatively low load state, which is not conducive to the operation and energy saving of the main engine

[0004] (2) In the past, the dredging fleet generally adopted the dredging fleet operation mode of "dredger + survey ship", that is, the survey ship measures the water depth data of the operation area, and then the dredger performs dredging operations. The time length, operation accuracy and efficiency are low, and the operation economy is not high
