Description
Technical field
The utility model relates to the capping of a kind of ships Side Thrusters, relates in particular to a kind of ships Side Thrusters capping of drag reduction noise reduction.
Background technology
Present many boats and ships have all been installed lateral thruster, make boats and ships rotary head or produce lateral displacement easily under than the low speed situation, and the maneuvering performance of boats and ships is significantly improved, especially the maneuvering performance during low speed.Lateral thruster is divided into bow lateral thruster and stern lateral thruster, using more lateral thruster is the bow lateral thruster, be installed in the cylindrical shape tunnel that the stem underwater traverses the warship bow, interior dress screw, the thrust of utilizing the jet of screw to produce changes the course of boats and ships.But it is linear that the installation of lateral thruster has also destroyed original hull simultaneously, makes the ship's navigation process produce resistance and bubble, not only influences ship speed, and the work of the sonar on the naval vessel is produced interference.
Summary of the invention
Technical problem to be solved in the utility model is to overcome defective of the prior art, the capping of using on a kind of warship lateral thruster is provided, in the existing crawl space of hull, capping is set, the keying of capping does not influence the operate as normal that shipboard pushes away device, when closing, keep the original linear of ship substantially, reduce ship resistance, reduce the lateral thruster noise, reduce interference sonar.
For solving the problems of the technologies described above, the utility model provides the capping of a kind of ships Side Thrusters, comprises
Circular cylinder body is located at the barrier of tackling foreign material in the cylindrical shell,
It is characterized in that comprise the fence gate that is located at the axial rotation around the shaft in the described cylindrical shell, described rotating shaft is located on the described fence gate, is axially rotated by the last shaft seat and the lower rotary shaft seat supports that are located on the described cylindrical shell.
Described rotating shaft be located at described barrier along described drum shaft to the plane of projection on.
Described fence gate comprises many fan leafs of synchronous or asynchronous operation.
Described rotating shaft is located at respectively near the centre position of the every blade parallel with the closed line of described many fan leafs or its.
Described fence gate make position in described cylindrical shell is provided with the spacing doorframe of a circle, is provided with water bar by described fence gate one side on described doorframe.
Involutory just when closed between the described blade, apposition position is provided with water bar.
Described fence gate and described cylindrical shell are radially angled to be obliquely installed, and the angle of inclination is linear close with the hull that ships Side Thrusters place is set.
Described rotating shaft is separated both sides inside and outside described fence gate with described barrier.
The keying of described fence gate is driven by hydraulic means.
The capping of described ships Side Thrusters is located at the two ends of boats and ships lateral thruster intake-outlet passage.
The beneficial effect that the utility model reached: ships Side Thrusters closure construction is simple, the opening/shutting mode uniqueness, the keying requisite space is less, does not influence the operate as normal that shipboard pushes away device when capping is opened, and capping does not exceed hull lines substantially, does not increase ship resistance; Good sealing effect when capping is closed keeps the original linear of ship substantially, and speed is unaffected when guaranteeing the ship navigation, has reduced the generation of bubble, has greatly reduced the interference to sonar.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1 and Figure 2, the capping of ships Side Thrusters comprises circular cylinder body 1, be located at the barrier 6 in the cylindrical shell 1, be located at the fence gate 2 in the cylindrical shell 1, can be axially rotated by rotating shaft 4 drives, preferable scheme is that fence gate 2 comprises two semicircular blade 2a, and two rotating shafts 4 are located at respectively on two blade 2a, rotating shaft 4 is located at the central spot with the perpendicular radius of the diameter of blade 2a semicircle, and parallel with the diameter of semicircle.Preferable scheme is that rotating shaft 4 is located at and runs through fence gate blade 2a length direction and the center of gravity by blade, and each rotating shaft is parallel to each other.Rotating shaft 4 is axially rotated by the last shaft seat 5 and 3 supports of lower rotary shaft seat that are located on the cylindrical shell 1.Fence gate 2 is obliquely installed with cylindrical shell 1 is radially angled, and the angle of inclination is linear consistent with the hull that ships Side Thrusters place is set, and after guaranteeing fence gate 2 closures, is consistent substantially with hull is linear.The keying of fence gate 2 is driven by hydraulic means, and when needing to open and close fence gate 2 under the situation that pressure is bigger under water, hydraulic means can provide bigger driving force.
As Fig. 2, shown in Figure 3, the schematic diagram during for fence gate 2 open modes, when fence gate 2 was opened, two blade 2a 4 axially rotated around the shaft, and fence gate 2 parts between two rotating shafts 4 are outwards rotated, and fence gate 2 parts are inwardly rotated outside two rotating shafts 4.The rotary motion trace of fence gate 2 and Side Thrusters 9 keep certain safe clearance, do not influence the work of Side Thrusters 9.
As Fig. 4, shown in Figure 5, the schematic diagram during for the fence gate closure state, during fence gate 2 closures, two blade 2a 4 axially rotate around the shaft, and rotation direction is opposite when opening with fence gate 2.After fence gate 2 closures, rotating shaft 4 separates barrier 6 in fence gate 2 inside and outside both sides, and barrier 6 plays the effect spacing to fence gate 2 simultaneously.Fence gate 2 make positions in cylindrical shell 1 are provided with the spacing doorframe 8 of a circle, are provided with water bar 7 by fence gate 2 one sides on doorframe 8, as shown in Figure 6; When two blade 2a were closed, the inboard was provided with water bar 7 on two adjacent limits, and as shown in Figure 7, water bar contacts with barrier 6, had good sealing property when guaranteeing fence gate 2 closures, reduced the generation of bubble.
After fence gate 2 closures, be consistent substantially with hull is linear, to reduce ship resistance.
Those skilled in the art can recognize, the rotation direction of fence gate 2 is not confined to the rotating manner mentioned in the present embodiment, can recognize equally, fence gate form of structure in the present embodiment is not confined to the capping as the ships Side Thrusters, is equally applicable to other and opens and closes the less occasion in space.
The capping of ships Side Thrusters is located at the two ends of boats and ships lateral thruster intake-outlet passage.When the capping of ships Side Thrusters is installed, need cylindrical shell is carried out shape cutting, to be fit to be installed to the position and the shape of shipping lateral thruster.
Seat board of using when cylindrical shell, fence gate and welding etc. all adopts shell steel and/or 316L stainless steel.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection domain of the present utility model.
