Abstract

The utility model discloses a blade rotation type screw is suitable for the speed of traveling and the direction of traveling of adjusting ship. The propeller comprises a remote control storage battery engine, the remote control storage battery engine is arranged on a fixed support, a large crown gear and a small crown gear meshed with the large crown gear are arranged at the output end of the remote control storage battery engine, blades are arranged on a small crown gear shaft, the small crown gear is meshed with the large crown gear, the small crown gear is uniformly distributed to ensure that the blades rotate at the same angle at the same time, and the large crown gear drives the small crown gear to rotate, so that the attack angle of the blades is changed. The ship can realize speed regulation and hovering or change the running direction of the ship by adjusting the attack angle of the paddle. The structure is simple, the use is convenient, and the practicability is strong.

Description

Blade rotating propeller

Technical Field

The utility model relates to a blade rotation type screw especially is applicable to a screw that ship can directly reverse.

Background

The propeller is a device which converts the rotational power of an engine into a propulsive force by means of the rotation of blades in the air or water. The propellers are divided into a plurality of types and are widely applied, such as propellers of aircrafts and ships, and the size and the direction of the driving force generated by the propellers are related to the attack angle of the blades, but the blades of the existing propellers are fixed and cannot be changed randomly, the rotating speed of a motor needs to be changed when the driving speed of the ship is required to be adjusted, the motor needs to be rotated reversely when the driving direction of the ship is required to be changed, and the influence on the motor caused by frequent change of the working state is large. Therefore, the propeller capable of changing the attack angle of the blades is designed, so that the size and the direction of the propelling force can be changed when the rotating speed of the motor is not changed, and the running speed and the running direction of the ship can be adjusted.

Disclosure of Invention

The utility model discloses an overcome not enough in having the screw, provide a simple structure, can realize the ship speed governing, hover and the blade rotation type screw of going backward in going.

In order to achieve the above object, the utility model discloses a blade rotation type screw, including remote control battery engine, remote control battery engine establish on the fixed bolster, remote control battery engine output be equipped with big crown gear and with a plurality of little crown gear of big crown gear engaged with, be equipped with the paddle on a plurality of little crown gear shafts respectively, little crown gear and big crown gear meshing guarantee the paddle and rotate the same angle simultaneously, big crown gear drives little crown gear rotatory to change the angle of attack of paddle.

The big crown gear is connected with the fixed support through a bearing.

The number of the small crown gears is 2-3, and the small crown gears are uniformly distributed.

Has the advantages that: since the technical scheme is used, the utility model discloses when the ship travel in-process want the speed governing, hover or reverse, can make big crown gear rotate earlier through remote control battery engine, it is rotatory to drive little crown gear simultaneously, and then makes the paddle incidence change to this changes the size and the direction of driving force, thereby makes the ship realize the speed governing, hover or reverse. The utility model has the advantages of simple structure, convenient use, low cost and wide practicability.

In the figure: 1-large crown gear; 2-small crown gear; 3-remote control of the accumulator motor; 4-fixing the bracket; 5-paddle.

Detailed Description

An embodiment of the invention is further described below with reference to the accompanying drawings:

as shown in fig. 1, the blade-rotating propeller of the present invention is mainly composed of a large crown gear 1, a small crown gear 2, a remote control battery motor 3, a fixed bracket 4 and a blade 5. Remote control battery engine 3 establish on fixed bolster 4, remote control battery engine 3 output is equipped with big crown gear 1 and a plurality of little crown gear 2 with big crown gear 1 looks meshing, is equipped with paddle 5 on a plurality of little crown gear 2 axles respectively, little crown gear 2 meshes with big crown gear 1, guarantees that the paddle rotates the same angle simultaneously, big crown gear 1 drives little crown gear 2 and rotates to change the angle of attack of paddle 5. The number of the small crown gears 2 is 2-3, the small crown gears are uniformly distributed to ensure that the blades rotate at the same angle at the same time, and the large crown gear drives the small crown gear to rotate, so that the attack angle of the blades is changed. The ship can realize speed regulation and hovering or change the running direction of the ship by adjusting the attack angle of the paddle. In the embodiment of the drawing, the number of the small crown gears 2 is 3, as shown in fig. 2, the 3 small crown gears 2 are uniformly distributed and meshed with the large crown gear 1, and the blades 5 can rotate at the same angle at the same time. The fixed support 4 is connected with the large crown gear 1 through a bearing, the large crown gear 1 can rotate relative to the fixed support 4 when speed regulation is needed, and the paddle 5 is fixedly connected to the small crown gear 2.

Claims
