Abstract
The utility model relates to ship devices, in particular to the improvement of a ship side pushing device. The ship side pushing device comprises a pipe barrel, wherein the pipe barrel is fixedly installed on a ship body and penetrates through two sides of the ship body. A side pushing propeller is fixedly installed inside the pipe barrel and is a controllable-pitch propeller. The ship side pushing device has the advantages of being simple in structure, free of frequently changing the working state of a main machine, and reliable in operation.
Description
Technical field
The utility model relates to equipment of Vessel, relates in particular to the improvement of boats and ships lateral thruster.
Background technology
When big-and-middle-sized boats and ships enter harbour or harbour, must rely on special service boats and ships will wait to approach the boats and ships push-and-pull of (or harbour) to assigned address, the service boats and ships are provided with axial advance device and lateral propelling.The axial advance device is installed in the boats and ships afterbody, promotes boats and ships and travels forward.Lateral propelling generally is installed in boats and ships stem position, is equipped with vertical with the ship stern tube shaft at the stem position and runs through the socket of hull both sides, is installed with the thruster screw propeller in this socket, but the socket two ends all device the cover plate of the folding of blanked-off pipe cylinder is arranged.The lateral thruster of this structure adopts the fixed pitch propeller of fixed pitch, can not well adapt to the variation of boats and ships operating mode, need the frequent mode of operation that changes main frame for the load that varies in size, this is to prolonging the main frame life-span, improve reliability, reduce oil consumption, raising economy etc. is all brought very large unfavorable factor.Boats and ships lateral thruster simple in structure, reliable, the mode of operation that do not need frequently to change main frame is still rare at present.
The utility model content
For the prior art above shortcomings, the purpose of this utility model is that a kind of boats and ships lateral thruster will be provided, it have simple in structure, do not need frequently to change the mode of operation of main frame, reliable characteristics.
In order to solve the problems of the technologies described above, the scheme of the utility model technical solution problem is: a kind of boats and ships lateral thruster, comprise the socket that is fixedly mounted on the hull and runs through the hull both sides, be installed with the thruster screw propeller in this socket, described thruster screw propeller is adjustable pitch propeller.
After adopting such scheme, because the thruster screw propeller is installed in socket, and the thruster screw propeller is adjustable pitch propeller, so boats and ships can be rotating speed at main frame and axle, turn in the constant situation, rotate blade by the adjusting mechanism in the propeller hub, change pitch angle, thereby change the size and Orientation of thrust, to adapt to the requirements such as speed change of boats and ships, blade angle slewing area is large, and axle system turns to the constant thruster that realizes opposite direction, and can improve the manoevreability of engine installation, main frame need not frequently to change operating mode, this improves reliability to prolonging the main frame life-span, reduces oil consumption, improving economy has very large benefit, and is easy to realize handling automation.
The thruster screw propeller is fixedly mounted on interior up and down each two crossbeam of socket, and crossbeam passes socket and is fixedly mounted on the hull.
The thruster screw propeller is fixedly mounted on interior up and down each two crossbeam of socket, and crossbeam is fixedly mounted on the wall of socket.
Blade on the thruster screw propeller is 3.
Blade on the thruster screw propeller is 4.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model boats and ships lateral thruster is described in further detail.
Fig. 1 is the front view of the structural principle scheme drawing of the utility model boats and ships lateral thruster.
Fig. 2 is the left view of the structural principle scheme drawing of the utility model boats and ships lateral thruster.
The specific embodiment:
Among Fig. 1, Fig. 2, boats and ships stem position is equipped with vertical with the ship stern tube shaft and runs through the socket 1 of hull both sides, be installed with rotating thruster screw propeller 3 in this socket 1, thruster screw propeller 3 is adjustable pitch propeller, thruster screw propeller 3 is fixedly mounted on up and down each two crossbeam 2 in the socket 1, and crossbeam 2 passes socket 1 and is fixedly mounted on (hull does not draw among the figure) on the hull.Blade 4 on the thruster screw propeller 3 is 3.The two ends of socket 1 be equipped with can controlled folding cover plate (the figure cover plate does not draw), closure flap then when thruster screw propeller 3 is not worked, when will working, then opens on thruster screw propeller 3 cover plate, because the thruster screw propeller 3 in socket 1 interior installation is adjustable pitch propeller, so boats and ships can be rotating speed at main frame and axle, turn in the constant situation, rotate blade by the adjusting mechanism in the propeller hub, change pitch angle, thereby change the size and Orientation of thrust, to adapt to the requirements such as speed change of boats and ships, blade angle slewing area is large, axle system turns to the constant thruster that realizes opposite direction, improved greatly the manoevreability of engine installation, main frame need not frequently to change operating mode, and this is to prolonging the main frame life-span, improve reliability, reduce oil consumption, improving economy has very large benefit, and is easy to realize handling automation.
