Tilt rotor vector propeller based on wave energy

Abstract

The invention discloses a tilt rotor vector propeller based on wave energy. The propeller comprises an airframe which is equipped with a wave energy conversion device, an accumulator, and at least two sets of tilt rotor vector propulsion devices. The wave energy conversion device and the tilt rotor vector propulsion devices are connected with the accumulator respectively, and the tilt rotor vector propulsion device comprises a hang-glider, a propulsion mechanism, a tilt drive motor and a tilt frame. One end of the hang-glider is fixed on the airframe, and the tilt frame is supported on the other end of the hang-glider. An output terminal of the tilt drive motor is connected with the tilt frame, and the propulsion mechanism is arranged on the tilt frame. The tilt rotor vector propeller based on the wave energy has the advantages of converting the wave energy into electric energy, supporting long-distance navigation, and realizing complicated actions such as rapid turning and horizontal tumbling and the like.

technical field [0001] The present invention relates to an underwater thruster, in particular to a tilting rotor vector thruster based on wave energy. Background technique [0002] The underwater thruster is actually a remotely operated vehicle. There are many types of propulsion methods for existing underwater propellers, such as ordinary propeller propellers, ducted propeller propellers, flat-rotating propellers, channel propellers and emerging magnetic fluid propellers, etc., and there are many types. Ordinary propeller propellers have a simple structure and are the most widely used, and have high propulsion efficiency, but it is difficult for a single ordinary propeller propeller to control the direction and attitude of the propelled object underwater; Invented by Cotter in 1934, it is a specially designed sleeve or duct on the outside of the propeller.

Problems solved by technology

Ordinary propeller propellers have a simple structure and are the most widely used, and have high propulsion efficiency, but it is difficult for a single ordinary propeller propeller to control the direction and attitude of the propelled object underwater; Invented by Cotter in 1934, it is a specially designed sleeve or duct on the outside of the propeller. When the propeller rotates forward, a negative pressure zone is formed in the front and a positive pressure zone is formed in the rear, thereby generating forward pressure. The thrust includes the thrust brought by the propeller's own rotation and the thrust generated on the duct, and also accelerates the water flow at the paddle disc, which improves the propulsion efficiency. Compared with the common propeller propeller with the same efficiency, the ducted propeller propels The size of the propeller is much smaller, which is conducive to the overall design of the robot and is easy to operate; the main working parts of the flat-rotating propeller are composed of 4-6 blades protruding from a disc, and the axis of the blade is in line with the disc. Vertically, the disk is connected to the propulsion shaft through the gear, by changing the relative position of the paddle and the disk, the thrust in any direction can be generated in a plane at right angles to the shaft, without rudder and rotating shaft, it has excellent Maneuverability and maneuverability, but because several blades cannot be in an effective propulsion state at the same time, the efficiency is much lower than that of ordinary propellers

However, the existing underwater thrusters are limited by propulsion technology, and there are still problems such as difficult attitude adjustment, low action sensitivity, and inability to adapt to complex changes in underwater topography.
