Abstract
The purpose of the present invention is to provide a kind of removable ducted propellers peculiar to vessel, including propeller, telescopic rod, regulating mechanism, detachable conduit, the detachable conduit includes the first conduit and the second conduit, the regulating mechanism includes first gear, second gear, first bevel gear, second bevel gear, first gear is meshed with the second gear, first bevel gear is meshed with second bevel gear, first gear is coaxial with second bevel gear, first gear connects the first conduit, second gear connects the second conduit, rotatable Bevel Gear Transmission axis is set in telescopic rod, second bevel gear is fixed on Bevel Gear Transmission axis.The present invention can close up or split according to operating condition, and when propeller load is heavier, conduit, which closes up, can increase airscrew thrust raising propeller efficiency.It falls to navigate in ship and conduit can be split and withdraws in conduit cabin by when turning, improve the maneuvering performance and the propeller performance of endurance of ship.
Description
Technical field
The present invention relates to a kind of marine propulsions, specifically propeller.
Background technique
Ducted propeller is to form in the periphery of propeller plus a ring duct, and the section of conduit is airfoil type or folding
Angle line type.Conduit can improve the efficiency of heavily loaded propeller, therefore be widely applied on the heavier ship of propeller load.With ship
To enlargement, high power development, the load of propeller is increasing, and propulsive efficiency not only can be improved in ducted propeller, but also
Be conducive to reduce vibration.But ducted propeller also has its disadvantage, such as increases the radius of gyration of ship, and maneuvering performance degenerates, ship
Oceangoing ship is poor etc. in the propeller performance of falling endurance, when especially water plant, sundries are involved in conduit, is easy at blade tip and catheter interstitial
It blocks, or winding blade, influences work, cause to sometimes have to parking process.
Summary of the invention
The purpose of the present invention is to provide can be according to one kind removable conduit peculiar to vessel for close up or splitting of operating condition
Propeller.
The object of the present invention is achieved like this:
Removable ducted propeller peculiar to vessel of the invention a kind of, it is characterized in that: including propeller, telescopic rod, regulating mechanism, removable
Divide conduit, the detachable conduit includes the first conduit and the second conduit, and the regulating mechanism includes first gear, the second tooth
Wheel, first bevel gear, second bevel gear, first gear are meshed with the second gear, and first bevel gear is mutually nibbled with second bevel gear
It closes, first gear is coaxial with second bevel gear, and first gear connects the first conduit, and second gear connects the second conduit, telescopic rod
In rotatable Bevel Gear Transmission axis is set, second bevel gear is fixed on Bevel Gear Transmission axis.
The present invention may also include:
1, when the first conduit and the second conduit close up, the ring structure for being located at propeller periphery is formed；First conduit and
After two conduits are split, respectively upwards with mutually rotation counterclockwise under drive of the first gear with second gear.
2, conduit cabin is arranged in the hull interior above propeller, after the first conduit and the second conduit rotate upwards, flexible
It is recoverable in conduit cabin under the drive of bar.
3, regulating mechanism is arranged in housing, and housing is streamlined structure.
Present invention has an advantage that the present invention can close up or split according to operating condition, it is heavier in propeller load
When, conduit, which closes up, can increase airscrew thrust raising propeller efficiency.Can conduit be split and be received when ship falls and navigates and turn
It returns in conduit cabin, improves the maneuvering performance and the propeller performance of endurance of ship.When thering is water plant, sundries etc. to be involved in conduit,
Be stuck between tip of propeller blade and conduit, or winding blade and influence propeller work normally when, openable propeller nozzle with
Make sundries Automatic-falling or easy cleaning.Both can be with keep the catheter propeller the advantages of, its disadvantage is in turn avoided.
Detailed description of the invention
Fig. 1 is the structural schematic diagram under closed configuration of the present invention；
Fig. 2 is the structural schematic diagram under disassembled form of the present invention；
Fig. 3 is the top view of regulating mechanism；
Fig. 4 is the side view of regulating mechanism.
Specific embodiment
It illustrates with reference to the accompanying drawing and the present invention is described in more detail:
In conjunction with Fig. 1-4, the present invention is made of telescopic rod 1, regulating mechanism 2, detachable conduit 3 and marine propeller 4 etc., is led
The fractionation of pipe 3 and closing up is adjusted by regulating mechanism 2.The regulating mechanism 2 that propeller nozzle tears conjunction open uses gear drive,
By gear 5, gear 6, bevel gear 7, bevel gear 8 and Bevel Gear Transmission axis 9 etc. are constituted.Bevel Gear Transmission axis 9 is by motor or hydraulic
Driving, band dynamic bevel gear 7, gear 5 and gear 6, to realize closing up and splitting for conduit 3.
Gear 5 and gear 6 are intermeshed, and gear 5 and gear 6 are fixed with two parts of propeller nozzle respectively, gear 5 with
Bevel gear 7 is coaxially fixed, and bevel gear 7 and bevel gear 8 are intermeshed.
Bevel Gear Transmission axis 9 can rotate driving bevel gear 7 in telescopic rod 1, and band moving gear 5 and gear 6 are led to adjust
Pipe tears conjunction open.
Conduit tear open the regulating mechanism 2 of conjunction housing be it is streamlined, to reduce resistance and improve flow field around propeller.
Propeller nozzle and its regulating mechanism can be retracted to the conduit that hull interior above propeller is arranged in through telescopic rod 1
In cabin.
The present invention can close up or split according to operating condition, and when 4 load of propeller is heavier, conduit 3, which closes up, to be increased
4 thrust of propeller is added to improve 4 efficiency of propeller.Conduit 3 can be split and be withdrawn in conduit cabin when ship falls and navigates and turn, changed
The maneuvering performance of kind ship and 4 performance of propeller of endurance.
