Description

Ship propeller

Technical field

The utility model relates to a kind of ship propeller, is meant a kind of ship propeller that drives with DC machine especially.

Background technology

Ship propeller is mounted on the ship side of hull, drives hull and advances or setback device.For reducing marine pollution, protect environment and resource, the motor-driven canoe of the water surface changes the fuel oil propelling unit into electric plating propulsion gradually.The CN2535324Y utility model patent discloses a kind of portable ship propeller, though use storage battery as propulsion source, DC motor directly drives propeller, but do not have the under-voltage indicating device of storage battery can cause the storage battery overdischarge and damage, DC machine and propeller are contained under water, the cruiseway pasture and water are many, and resistance is big, pasture and water winding screw slurry takes place often and cast anchor and suspend.

Summary of the invention

Technical problem to be solved in the utility model is a kind of DC machine direct drive propeller of using of problem design that runs at above-mentioned canoe propelling unit, adapts to the propeller propelling unit at many pasture and water surface navigation, improves canoe negotiation capability and efficient.

Design plan of the present utility model is, ship propeller, comprise bar handle and control capsule, with control capsule bottom bonded assembly standpipe, be located at supply line and control line in the standpipe, be located at the guiding rudder clamper and the guiding rudder and the propeller that are located at the standpipe lower end of standpipe periphery, it is characterized in that establishing in the control capsule battery tension indicating device, DC machine is located in the leak free guiding rudder, motor output shaft and propshaft direct connection; Propeller blade is a wedge shape cutting blade.

Described propeller blade is that the asymmetric blade butt joint of streamline contour is formed by two joint sides.

Described guiding rudder by leak free bullet point, go up sleeve pipe, motor sleeve and guiding fin one and form, the bullet point, go up sleeve pipe and guiding fin, motor sleeve are held sealed engagement greatly with sealing bullet point.

Described guiding rudder is by last sleeve pipe and standpipe socket, horizontal chuck by clamper is clamped on the ship side, the fixed mount right flank is an arc surface, the pipe box of establishing in the middle of the fixed mount can be in arc surface the rotational positioning auto lock, the angle of inclination of automatic compensation standpipe is to keep safety of navigation when being beneficial to ship and pulling in to shore.

Compared with prior art, advantage of the present utility model is that with DC machine direct drive propeller under-voltage can show, has solved when propeller runs into the problem of pasture and water winding and runs into obstacle and can automatic tripping adjust angle.Simple in structure, it is low to consume energy, and noisiness is little, not polluted-water.

The specific embodiment

Ship propeller comprises handlebar 1 and control capsule 2 as shown in Figure 1, establishes governor and cell pressure indicating device 3 in the control capsule, and power lead 5 is connected with storage battery in the control of access box 2, is connected with direct motor 17 in the rudder for ship by standpipe 15.Captiveed joint with control capsule 2 by top connection 4 in standpipe 15 upper ends.Establish rudder for ship clamper 9 in the middle of the standpipe 15, guiding rudder clamper 9 is enclosed within standpipe 15 peripheries by sleeve pipe 10 and can relatively rotates.Standpipe 15 ends are captiveed joint with guiding rudder bullet point 14 by last sleeve pipe 16.Bullet point 14 is tightly connected with motor seal sleeve 18.The output shaft 21 of

motor

17 and 19 coaxial connections of propeller.

The control circuit of DC motor 17 is located in the control capsule 2, and cell pressure indicating device 3 is installed on the control capsule 2, and voltage indicator 3 also can connect semiconductor luminotron and whether under-voltagely show.

The rudder clamper 9 that leads as shown in Figure 2 comprises fixed mount 11, with sleeve pipe 10 in the middle of the horizontal chuck 8 of establishing fixed mount 11 left sides, fixed mount 11 be located at the rotatable spacing chuck 23 on sleeve pipe 10 right sides, establish square hole 12 in the arc surface on fixed mount 11 right sides, the two is connected fixed mount 11 and sleeve pipe 10 by rotating shaft 13.Spanner 22 is housed on the sleeve pipe 10, the two is connected by rotating shaft 24, spacing chuck 23 is peripherally equipped with retracing

spring

25,23 1 of spacing chucks link to each other with spanner 22, the other end end stretches out sleeve pipe 10 and to be located at fixed mount 11 arc surface upper aperture 12 corresponding, terminal meeting escape in square hole 12 embeds in the arbitrary square hole in the next square hole 12 when rotational fixation frame 11.When running into obstacle, it is the center rotation with rotating shaft 13 that external force makes sleeve pipe 10, spacing chuck 23 can be along the 12 displacement automatic compensation angles of the square hole on the arc surface, when ship navigates by water in the shoal water zone, run into obstacle or when stranded, the guiding fin 20 of guiding rudder is obstructed and upwards lifts, fixed mount 11 is that the center relatively rotates with rotating shaft 13, the end of spacing chuck 23 is jumped another square hole 12 and auto lock from a square hole 12, to adapt to different water-bed environment navigation.
