Adjustable nozzle propeller of ship

Abstract

The invention discloses an adjustable nozzle propeller of a ship. The adjustable nozzle propeller comprises a shaft sleeve, wherein paddles are arranged on the shaft sleeve in a circumferential direction, curve-shaped water inlets and curve-shaped water outlets are respectively formed in inner chambers of the paddles, the water inlets communicate with the shaft sleeve, T-shaped slots are formed in the middle parts of the inner chambers of the paddles, the water inlets and the water outlets are connected through spiral hoses, and the spiral hoses are positioned in the inner chambers of the T-shaped slots, curve-shaped blocks are arranged on the lower sides of the T-shaped slots, shears-fork type expansion brackets are arranged on the lower sides of the curve-shaped blocks, grooves are formed in two sides of the T-shaped slots, springs are arranged in the inner chambers of the grooves, and the upper ends of the springs are connected with the spiral hoses. The adjustable nozzle propeller disclosed by the invention adopts the manner of adjusting the angle of the curve-shaped spray waterway to adjust the size of the deviating force from the circumferential direction of the propeller, so that the adjustment the rotating speed of the propeller can be realized; according to navigation requirements of the ships, the navigational speed can be adjusted, and the adjustable nozzle propeller is energy-saving, environmentally-friendly, and suitable for general popularization

Description

technical field [0001] The invention relates to the technical field of ship machinery, in particular to an adjustable nozzle propeller of a ship. Background technique [0002] The propeller of the ship adopts the structure of the curved nozzle, which will receive the circumferential deflection force under the action of hydrodynamic force, so as to realize the rotation of the blade, which can not only increase the speed of the ship, but also save fuel resources. For small ships, the nozzle propeller It can be used as a power source throughout the whole process, saving navigation costs and protecting the environment. However, the traditional nozzle propeller has no adjustment function, and the rotation speed of the propeller is directly determined according to the size of the hydrodynamic force, which brings a lot of unnecessary troubles to the navigation of the ship. Therefore, We present an adjustable nozzle propeller for ships. Contents of the invention [0003] The obje...
