Description
Technical field
The utility model relates to a kind of ship power propulsive mechanism, refers in particular to a kind of liftable twin screw propelling unit.
Background technology
At present, the propeller of general ship all is fixed on stern, and mostly is single double helix oar, and for screw propeller provides the how parallel and ship working direction of transmission shaft of power, and transmission shaft is fixed on stern and can not moves.This propeller is applied on the large ship, can not produce distinct issues, when still being applied in it on small-sized ship, has many deficiencies.The hull of small boat is less, and the draft in water changes can be because the size variation of carrying capacity be bigger.The waters that small boat is travelled is than large vessel complexity, and some areas depth of water is more shallow, and the foreign material of pasture and water and so on are arranged in the navigation channel; Therefore, when the draft of ship changes, screw propeller will will run into many obstructions in water.When the hull draft was more shallow, screw propeller can not be immersed in fully in the water and make the propelling thrust deficiency; When hull drinking water was dark, screw propeller easily ran into obstacle and damages at complex water areas.
As a kind of patent No. is a kind of propeller device that is applicable to many pasture and water water-area navigation boats and ships of CN86201339; it is on the propeller hub and bracing strut of common screw propeller; moving knife and stationary knife group are installed respectively; shear the long pasture and water that flow into therebetween, to reach the protection screw propeller not by the purpose of pasture and water winding.Its technology is complicated, when pasture and water are more, can not initiatively avoid, can only passive removings pasture and water, when device damage, be difficult for repairing.And do not solve the screw propeller draft and change the problem of bringing.
The propeller that on amphibious vehicle, uses; need overcome above shortcoming especially; amphibious vehicle is when land locomotion; need pack up propeller to reduce resistance to motion and protection propeller; when amphibious vehicle advances in water; propeller need be deep into certain depth under water, could advance by actv. promotion amphibious vehicle.
Summary of the invention
The utility model mainly is at the fixing problem such as can not move of existing in prior technology propeller, provides a kind of rational in infrastructure, up and down the liftable twin screw propelling unit of folding and unfolding.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: liftable twin screw propelling unit, it is installed in stern, two propellers are symmetrically distributed on the quarter, propeller comprises seal casing and expansion link, seal casing one end is equipped with main driving axle, main driving axle is fixed on stern, and the seal casing other end is equipped with auxilliary transmission shaft; Expansion link one end is fixed on stern, and the other end has an end of auxilliary transmission shaft to be connected with seal casing; Main driving axle bridges on two walls of seal casing, and auxilliary transmission shaft bridges on two walls of seal casing.
Expansion link elongates or shortens and can drive auxilliary transmission shaft and rotate around main driving axle, and seal casing covers on outside auxilliary transmission shaft and the main driving axle, plays the fixedly effect of main driving axle and auxilliary transmission shaft, and can play waterproof effect.The propeller symmetry is installed in stern, plays and adjust the course, keeps effects such as balance jointly.
Main driving axle bridges on two walls of seal casing, and auxilliary transmission shaft bridges on two walls of seal casing
As preferably, described expansion link is the electric expansion bar; Its volume is little, and is in light weight, so force of inertia is less; when unexpected overload or when stopping, big impact can not take place, can be in given range pulsation-free automatically regulating haulage speed; commutation can realize the conversion of straight reciprocating motion easily more conveniently, realizes overload protection easily.
As preferably, on the described auxilliary transmission shaft screw propeller is installed.Screw propeller is installed in auxilliary transmission shaft one end, and auxilliary transmission shaft drives the screw propeller rotation, makes screw propeller to rotate around main driving axle simultaneously.
As preferably, be belt-driving or chain gear between main driving axle and the auxilliary transmission shaft; Belt-driving can prevent overload, absorb vibration; And be fit to high rotating speed transmission.
When liftable twin screw propelling unit of the present utility model was applied on the amphibious vehicle, electric pushrod was regained when amphibious vehicle travelled on the coast, and guaranteeing on the coast can trouble-free operation.When travelling in the water, the electric pushrod elongation promotes screw propeller and gos deep in the water, makes screw propeller that enough drafts be arranged, and guarantees normally operation in water.
Liftable twin screw propelling unit is specially adapted to the driving waterborne of water route amphibious vehicle, and this device is compared with traditional propeller, and following advantage is arranged: guarantee to have enough drafts, disembarkation and following water can be finished the lifting of screw propeller automatically.
