Description

Adjustable device Propeller for ship Technical Field The application relates to the technical field of marine propellers, in particular to an adjustable marine propeller. Background The marine propeller is a core component of a marine propulsion system, and rotates to push water flow to generate reaction force, so as to drive the marine vessel to advance or retreat. The thrust efficiency is directly affected by the shape and angle design of the wing section of the blade. The propeller is usually made of copper alloy and has the characteristic of seawater corrosion resistance. When the ship is in operation, the propeller transmits engine power through the shafting, and the ship is pushed to advance by utilizing the hydrodynamic principle in rotation. The publication number CN221809824U discloses a marine propeller, and this patent is convenient for dismantle single paddle to adopt the same mode to carry out fixed mounting to single paddle, make be convenient for change single paddle, save the use cost of screw, reduce the waste of resource. Although this patent is convenient for dismantle and change single paddle, the screw of this patent adopts distance structural design, and when high-speed navigation, the water flow resistance that the screw received increases under the high rotational speed, makes motor load increase, appears that the motor generates heat, power loss rises scheduling problem. When the ship is operated in an overload state for a long time, the insulation aging and the mechanical part abrasion in the motor can be aggravated, the service life of the motor is shortened, and the maintenance cost and the fault risk of the ship are increased. Disclosure of utility model In order to solve the problems, the application provides an adjustable marine propeller. The adjustable marine propeller provided by the application adopts the following technical scheme: an adjustable marine propeller comprises a shell, wherein a plurality of paddles are arranged on the outer side of the shell, and an adjusting assembly is arranged in the shell; The adjusting component comprises a driving component and an adjusting component, the adjusting component comprises a sliding block, the outer end of the sliding block is fixedly connected with a plurality of connecting blocks, one ends of the connecting blocks are connected with rotating rods, and one end of each rotating rod is connected with a rod body; The number of the rod bodies is four. Through the technical scheme, when the adjusting assembly sails at a high speed, the pitch angle of the blade can be dynamically adjusted according to the water flow resistance and the load of the engine, so that the effects of reducing the water flow resistance of the propeller and relieving the load of the motor of the propeller are achieved, and the problems of heating and power loss of the motor of the propeller caused by high-speed overload are effectively avoided. Further, the driving part comprises a hydraulic cylinder, the hydraulic cylinder is positioned in the shell, and the output end of the hydraulic cylinder is fixedly connected with a push plate. Further, the inside fixedly connected with connecting rod of casing, slider and connecting rod sliding connection. Further, the push plate is fixedly connected with one end of the sliding block, and the push plate is in sliding connection with the connecting rod.
