Description
Technical Field
The utility model relates to a trailing suction is accessory field for the ship, concretely relates to adjustable double nozzle is spouted to hydraulic drive bow of self-propelled trailing suction dredge.
Background
The self-propelled trailing suction dredger has wide application range in dredging operation and is a main ship type in the dredging industry. The self-propelled trailing suction dredger does not need anchoring during dredging operation, so that the dredging dredger has the characteristic of no obstacle to navigation, is not only used for dredging operation of deepening and maintaining a channel, but also is largely used for large-scale dredger fill land making operation.
The bow spraying is a process for conveying a large amount of sand to a shoal or a bank by a drag suction dredger, is mainly used for conveying a large amount of sand to a river bank, does not have the condition of laying an overwater pipeline at the initial stage of a rapid hydraulic fill land-making project, is suitable for adopting a bow blowing filling process, and directly sprays slurry to an operation area by the dredger through a spray pipe nozzle of a bow. Beach sand replenishing is usually performed near the coast by using bow jet, and islands can also be built by using bow jet in open water.
The current work includes: the requirements of throwing, blowing and spraying are various, different areas have different requirements on side slopes, the requirement on environmental protection is high, and the environment is easily affected by the poplar dust in the ship bow spraying operation, so that different bow spraying angles are selected according to the meteorological condition and the bow spraying falling point to meet the requirements on spraying distance and spraying height.
The angle of the nozzle of the forward spray is fixed, so that the spray range is fixed in the operation, the nozzle is not suitable for certain operations which have requirements on a hydraulic filling area, and the environmental pollution can be caused. The adjustment of the spray angle and the spray distance by moving the vessel is costly and also imposes a large operational burden on the crew due to frequent replacement.
In order to solve the above problems, we have made a series of improvements.
