Abstract
The invention relates to a power device, in particular to a ship underwater power device. The ship underwater power device includes propellers, a transmission shaft , a protection housing, a transmission rod, and a turbine assembly; the transmission shaft is arranged in the protection housing; a plurality of propellers are arranged on the transmission shaft at intervals; the transmission rod is arranged on the back end of the transmission shaft; and one end of the transmission rod extends above the protection housing, and the other end of the transmission rod is connected to the transmission shaft through the turbine assembly. The propellers are arranged in the protection housing, and then the problem that the conventional propellers are directly exposed outside can be solved, and damage to life entities due to exposed propellers can be effectively avoided; and a filtering screen arranged on a front opening of the protection housing can effectively prevent damage to the propellers due to foreign matters, and the service life of the propellers can be prolonged. The ship underwater power device is specially used in ships and boats.
Description
Technical field
The present invention relates to a kind of power set, and in particular to a kind of underwater power pack peculiar to vessel.
Background technology
As mankind ocean is explored and the increase of research activitiess, the accident of boat propeller injury aquatile and the mankind is not
It is disconnected to increase.Count according to U.S.West Coast Security Force, from 2005 to 2013 years, the accident occurred between ship propellers and diver
636 diver's injuries are caused, 38 divers are therefore dead.Injured 442 people and 29 people of death are because and spiral
Oar there occurs directly shock.It is therefore seen that, this is the statistics of U.S.'s propeller for vessels casualty accident in local marine site in a short time,
Worldwide, this data will be greatly increased.Exposed propeller is pacified except the life to aquatic organism and diver
Cause entirely outside greatly threatening, it also suffers from the impact of other factors, such as in navigation, propeller cuts with scissors ordinary ships
Winding etc. to hard thing or by ribbon can all cause propeller to damage and cause the ship cannot normal/cruise.
The content of the invention
It is an object of the invention to：A kind of novel in design, simple structure is provided, it is big while realizing improving fltting speed
Width improves the underwater power pack peculiar to vessel of security performance.
The technical scheme is that：
A kind of underwater power pack peculiar to vessel, including propeller, power transmission shaft, protective casing, drive link and turbine assembly, its feature exists
In：Built with power transmission shaft, interval is provided with multiple propellers to protective casing on power transmission shaft, and the rear end of power transmission shaft is provided with transmission
Bar, one end of drive link extends to protective casing top, mutual by turbine assembly between the other end and power transmission shaft of drive link
Connection.
Described protective casing is cylindrical body, and on the front port of protective casing filter mantle is provided with.
Flow guide protection cover is installed on described turbine assembly.
Described flow guide protection cover is conical hollow body, and the rear end of flow guide protection cover is provided with end cap.
Described protective casing both sides are provided with inlet opening.
The beneficial effects of the present invention is：
Powerplant configuration is simple under the marine water；Increase a protective casing by giving propeller, so as to solve spiral shell existing
The direct exposed problem of rotation oar, effectively prevent exposed propeller and hurts innocent persons the risk of life entity.Before protective casing
The filter mantle of port can effectively prevent foreign body from flowing into the damage caused to propeller, improve the service life of propeller.The ship
Front end water inlet is employed with the protective casing of underwater power pack greatly, the little design of rear end outlet, while in water conservancy diversion protection
Under the cooperation of cover so that propeller increases the hydraulic pressure inside protective casing during work operation, so as to increased out
The flow velocity of water at the mouth of a river, and then reached the purpose of increase propulsive force.
Description of the drawings

Specific embodiment
The underwater power pack peculiar to vessel includes propeller 1, power transmission shaft 2, protective casing 3, drive link 4 and turbine assembly 5, prevents
Built with power transmission shaft 2, interval is provided with multiple propellers 1 to protective case body 3 on power transmission shaft 2, and the rear end of power transmission shaft 2 is provided with drive link
4, one end of drive link 4 extends to the top of protective casing 3 and be connected with power-equipment, the other end and power transmission shaft 2 of drive link 4 it
Between be connected with each other by turbine assembly 5, thus at work drive power transmission shaft 2 rotate, and then drive propeller 1 rotate.
The protective casing 3 of the underwater power pack peculiar to vessel is cylindrical body, and on the front port of protective casing 3 filter mantle is provided with
6, to prevent water in foreign body enter to propeller 1 formed winding or damage propeller 1.
Flow guide protection cover 7 is installed on turbine assembly 5.Flow guide protection cover 7 is conical hollow body, after flow guide protection cover 7
End is provided with end cap 8, and to maintain easily and overhaul, the purpose one of flow guide protection cover 7 is to 5 protective actions of turbine assembly two
It is that shunting action is risen to the current in protective casing 3, to increase thrust.
The both sides of protective casing 3 are provided with inlet opening 9, to increase the inflow in protective casing 3.
The underwater power pack peculiar to vessel is installed on the bottom of hull, during work, aboard ship by passing in the presence of motor
Lever 4 drives power transmission shaft 2 to rotate, and then drives propeller 1 to rotate, and thus promotes hull to move ahead, during this, Jing inlet openings
9 and filter mantle 6 flow through the supercharging of propeller 1 by the outlet Accelerating Removal of protective casing 3 into the water in protective casing 3 and obtain
Obtain recoil strength.
The underwater power pack peculiar to vessel coordinates propeller due to being mounted with the flow guide protection cover 7 of taper on turbine assembly 5
1, so as to increased the flow velocity in exit, improve propulsive force.Under the driving effect of same torque, undoubtedly will improve
Propulsive efficiency.And the energy to be consumed also greatly reduces, effect of energy-conservation is reached.
Powerplant configuration is simple under the marine water；It is existing so as to solve by increasing a protective casing 3 to propeller 1
There is propeller directly exposed problem, effectively prevent exposed propeller and hurt innocent persons the risk of life entity.Protection
The filter mantle 6 of the front port of housing 3 can effectively prevent foreign body from flowing into the damage caused to propeller 1, improve the use of propeller 1
Life-span.The protective casing 3 of the underwater power pack peculiar to vessel employs front end water inlet greatly, the little design of rear end outlet, while
Under the cooperation of flow guide protection cover 7 so that propeller 1 increases the hydraulic pressure inside protective casing 3 during work operation,
So as to increased the flow velocity of water outlet water, and then the purpose for increasing propulsive force is reached, be particularly well-suited to existing ship, ship and install
Use.
