Abstract
The utility model discloses a dual-drive ship which is invented in order to solve insufficient pushing force and other problems of the prior art. The ship comprises a ship body; the ship body comprises a cabin and propellers; a power unit is arranged in the cabin, and is connected with the propellers through transmission devices; and the propellers are arranged at the head part and the tail part of the ship body, and correspondingly comprise a front propeller and a rear propeller. In the structure, because the front part and the rear part of the ship body are provided with the propellers, the dual-drive ship is driven by the power unit and respectively drives the front and the rear propellers to work simultaneously through the transmission devices, greatly improves the pushing force, and has the advantages of simple structure, easy manufacturing and wider scope of application.
Description
Technical field
The utility model relates to a kind of boats and ships, especially is provided with forward and backward angle of rake pair of driving boats and ships.
Background technology
Marine propeller is the instrument that thrust is provided on the boats and ships, and its effect is that the power conversion that marine powerplant provides is become thrust, advances boats and ships; The mechanism that the promotion boats and ships advance converts natural force, manpower or mechanical energy to the energy converter of boats and ships thrust; Propelling unit can be divided into active and reaction equation two classes by the mode of action.It is active driving by manpower or wind-force that fibre, sail (seeing sailing boat) that ship advances wait, and oar, big shield, paddle wheel, waterjet propulsor, screw propeller etc. are reaction equation.The modern transportation boats and ships adopt the reaction equation propelling unit mostly, and most widely used is screw propeller; The propelling unit that screw propeller is made up of propeller hub and some blades that radially is fixed on the hub is commonly called as Propeller Blade; Screw propeller is installed on the stern underwater, is obtained power and is rotated by main frame (seeing marine powerplant), push water to ship after, utilize the antagonistic force of water to push boat and advance; But this kind rear-mounted propeller propelling thrust deficiency, efficient obviously reduces when improving rotating speed, and is easy to generate the cavity phenomenon.
The utility model content
In order to overcome above-mentioned defective, the purpose of this utility model is to provide a kind of simple in structure, two driving boats and ships that propelling thrust is bigger.
In order to achieve the above object, of the present utility model pair of driving boats and ships, comprise hull, described hull is provided with cabin and propelling unit, be provided with engine installation in the described cabin, described engine installation is connected with described propelling unit by driving device, and described propelling unit is arranged on the head and the afterbody of described hull, corresponds to forward propeller and after propeller.
Wherein, described cabin is arranged on described mid-ship, and described driving device connects forward and backward propelling unit respectively.
Wherein, described cabin is two, be separately positioned on the head and the afterbody of hull, correspond to forward engine room and after engine room, the engine installation that is arranged in the forward engine room is connected with described forward propeller by first driving device, and the engine installation that is arranged in the after engine room is connected with described after propeller by second driving device.
Further, described forward and backward propelling unit is respectively propeller.
Above-mentioned structure owing to before and after the hull propelling unit is set all, under the driving of engine installation, drives forward propeller respectively and after propeller is worked simultaneously by driving device, has improved propelling thrust greatly.
Description of drawings
Fig. 1 is the structural representation of first specific embodiment of the present utility model.
Fig. 2 is the structural representation of second specific embodiment of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1 and Figure 2, two driving boats and ships of first specific embodiment of the present utility model, comprise hull 1, described hull is provided with cabin 2 and propelling unit, be provided with engine installation 3 in the described cabin, described engine installation is connected with described propelling unit by driving device 4, and described propelling unit is arranged on the head and the afterbody of described hull, corresponds to forward propeller 5 and after propeller 6.Wherein, described cabin 2 is arranged on described hull 1 middle part, and described driving device 4 connects forward and backward propelling unit respectively.Further, described forward and backward propelling unit is respectively propeller.Described forward and backward propeller is separately positioned on the front and back ends of the output shaft 40 of driving device, and described forward and backward propeller rotation direction is identical, promotes current backward simultaneously, advances by the antagonistic force of water.
Above-mentioned structure, only need on the basis of boats and ships original structure, the output shaft of lengthening driving device gets final product, and promotes front and back propeller work simultaneously by an engine installation that is provided with in the mid-ship cabin, makes position, hull front and back obtain propelling thrust respectively, under engine speed unmodified situation, the propelling thrust of propeller obviously strengthens, and propulsion coefficient improves, and is simultaneously simple in structure, handling ease is widely used.
As second specific embodiment of the present utility model, described cabin is two, be separately positioned on the head and the afterbody of hull, correspond to forward engine room 21 and after engine room 22, the engine installation 31 that is arranged in the forward engine room is connected with described forward propeller 5 by first driving device 41, and the engine installation 32 that is arranged in the after engine room 22 is connected with described after propeller 6 by second driving device 42.
Above-mentioned structure, head and the afterbody at hull is provided with the cabin respectively, and structure is compact more, and mechanical loss is less, and transmission structures is simple, and load is low, is suitable for large ship.
The utility model is not limited to above-mentioned embodiment, no matter do any variation on its shape or structure, every to utilize above-mentioned two driving boats and ships all be a kind of distortion of the present utility model, all should think and drop within the utility model protection domain.
