Description
Technical Field
The utility model relates to a trailing suction is accessory field for the ship, concretely relates to big freedom ball-twist regulation double jet nozzle of self-propulsion 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 in 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 Sterland Koronto engineering accepted by the company contains throwing, blowing and spraying, different areas have different requirements on the side slope, and meanwhile, the requirement on environmental protection is high, and the raised dust in the bow spraying operation of the ship is easy to influence the surrounding environment, so different bow spraying angles are required to be selected according to the meteorological condition and the bow spraying falling point so as 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.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a big degree of freedom ball hank of self-propulsion trailing suction hopper dredger adjusts double jet to overcome the above-mentioned shortcoming and not enough that prior art exists.
A high-freedom ball-jet-cutter adjusting double nozzle of a self-propelled trailing suction hopper dredger comprises: the device comprises a bow, a fixed nozzle mechanism and an adjustable nozzle mechanism, wherein the fixed nozzle mechanism is connected with the upper end of the bow, and the adjustable nozzle mechanism is connected with the lower end of the bow;
wherein the adjustable nozzle mechanism comprises: the hydraulic support comprises a first ball hinge, an oil cylinder, a first eye plate, a second eye plate, a first bent pipe, a first nozzle, a first straight pipe and a first flange, wherein the first ball hinge is connected with the lower end of a bow through the first straight pipe, the first eye plate is connected with the front end of the bow, the second eye plate is connected with the first bent pipe, the oil cylinder is connected with the first eye plate and the second eye plate in the middle, one end of the first bent pipe is connected with the first ball hinge, and the other end of the first bent pipe is connected with the first nozzle in a welded mode through the first flange.
Further, the fixed nozzle mechanism includes: the second spherical hinge is connected with the upper end of the bow, one end of the second straight pipe is connected with the second spherical hinge, the other end of the second straight pipe is connected with the second bent pipe, and the second nozzle is connected with the second bent pipe through the second flange in a welded mode.
The utility model has the advantages that:
compared with the prior art, the utility model, through install adjustable nozzle mechanism additional on the tradition possess single fixed nozzle mechanism's boats and ships, easy operation has improved the spray regime, can spout the drop point according to meteorological condition and bow, selects different bow to spout the angle in order to satisfy the jet distance, spout high requirement, reduces the pollution to the surrounding environment.

Detailed Description
The present invention will be further described with reference to the following examples. It should be understood that the following examples are illustrative only and are not intended to limit the scope of the present invention.
Example 1
Fig. 1 is a schematic structural diagram of the present invention.
As shown in fig. 1, a high-freedom ball-jet adjusting double nozzle of a self-propelled trailing suction hopper dredger comprises: the device comprises a bow 100, a fixed nozzle mechanism 200 and an adjustable nozzle mechanism 300, wherein the fixed nozzle mechanism 200 is connected with the upper end of the bow 100, and the adjustable nozzle mechanism 300 is connected with the lower end of the bow 100;
wherein, adjustable nozzle mechanism 300 includes: first ball hank 310, hydro-cylinder 320, first eye board 330, second eye board 340, first return bend 350, first nozzle 360, first straight tube 370 and first flange 380, first ball hank 310 is connected with bow 100 lower extreme through first straight tube 370, first eye board 330 is connected with bow 100 front end, second eye board 340 is connected with first return bend 350, hydro-cylinder 320 and first eye board 330 and second eye board 340 intermediate junction, first return bend 350 one end is connected with first ball hank 310, the first return bend 350 other end passes through first flange 380 and 360 welded connection of first nozzle.
The fixed nozzle mechanism 200 includes: the second ball hinge 210 is connected with the upper end of the bow 100, one end of the second straight pipe 220 is connected with the second ball hinge 210, the other end of the second straight pipe 220 is connected with the second bent pipe 230, and the second nozzle 240 is connected with the second bent pipe 230 through the second flange 250 in a welding manner.
The utility model discloses an operating principle is, installs the second ball hank on traditional trailing suction hopper dredger's bow spouts the device, installs a set of adjustable nozzle mechanism 300 additional simultaneously, installs adjustable nozzle mechanism 300 at bow 100 lower extremes, constitutes big degree of freedom ball hank and adjusts double-nozzle structure, and the advantage of this kind of structure enlarges the adjustable range of double-nozzle structure, realizes wider adjustment. The bow spraying operation of the traditional trailing suction dredger adopts a single fixed nozzle mechanism, and because the limit of a single ball winch is generally 15 degrees, the traditional trailing suction dredger is not suitable for areas with requirements on a hydraulic filling area and can cause environmental pollution. The utility model discloses to the conventional art, realize the design of two ball hanks, though the structure is complicated, the transformation cost is higher, nevertheless can carry out the adjustment of bigger angle under the special circumstances, improved spray range, can spout the drop point according to meteorological condition and bow, select different bows to spout the angle in order to satisfy and spout apart from, spout high requirement. Two ball hanks are compared with single ball hank, install the second ball hank where, is the utility model provides a technical scheme one of, we change the first section straight tube of traditional lower extreme, and the scope that on the one hand adjustment cost reduction like this, on the other hand spray tube are adjustable also more strengthens.
The above description has been made of the embodiments of the present invention, but the present invention is not limited thereto, and various changes may be made without departing from the spirit of the present invention.
