Description

A kind of hydraulic reset double propeller motor ship

technical field

The utility model relates to a hydraulically reset double-blade motor ship, which belongs to the technical field of ships, and in particular relates to a double-blade motor ship.

Background technique

Most propellers used in traditional ships are propellers. Although they are easy to drive, their efficiency is low. The manufacturing process of the blades is complicated, and wakes will be generated when they are used; After the leaf enters the water and before the water exits, the water resistance is relatively large and the thrust produced is very small, the energy loss is large, the efficiency is low, and the noise is large. Authorized notification number is the patent of CN100360378C, discloses a kind of bionic flat ship propeller, although efficiency is higher, structure is more complicated.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the traditional ship technology, and to invent a more efficient hydraulically reset double-bladed motor ship.

The utility model relates to a hydraulically reset double-blade motor ship, which includes a hull, an engine, a hydraulic workstation and a propeller. The power of the engine is transmitted to the propeller through the transmission mechanism. The hydraulic workstation controls the hydraulic mechanism of the thruster. The propeller is installed at the stern of the hull. The concrete structure of propeller is: it comprises left plate blade, right plate blade, hydraulic mechanism, square pipe, left frame shaft, right frame shaft, gear set and rudder. The square pipe is surrounded by a left side board, a top board, a right side board and a bottom board. The left side board and the right side board are vertically arranged, and the top board and the bottom board are arranged horizontally. The opening direction of the square pipe is the front-to-back direction. The left frame shaft and the right frame shaft have the same structure, and they are symmetrically arranged vertically on the left and right sides of the middle of the square tube, and their respective upper and lower ends are respectively connected with the top plate and the bottom plate of the square tube through bearings. Gear set comprises left gear and right gear, and left gear and right gear are identical, and they are respectively installed in the upper end of left frame shaft and the upper end of right frame shaft. The left gear and the right gear are placed outside the square tube and positioned on the top of the square tube, and they are meshed with each other, and the transmission ratio of their meshing is 1:1. The left flat blade is the same as the right flat blade, and the ratio of their height to width ratio is between 1 and 3. The left flat blade and the right flat blade are symmetrically installed inside the square tube, they are all perpendicular to the base plate of the square tube, and they pass through the elongated holes in the middle section of the left frame shaft and the right frame shaft respectively. The rear end of the hydraulic mechanism is "T" shaped, and the hydraulic mechanism is longitudinally installed between the left frame shaft and the right frame shaft. The hydraulic mechanism moves back and forth, and the effect of the hydraulic mechanism is to pull the left flat blade and the right flat blade from the rearmost position to the frontmost position. The power to drive the rotation of the left flat blade and the right flat blade is input from the upper end of the left frame shaft or the upper end of the right frame shaft. In order to prevent the left flat blade from slipping out of the elongated hole in the middle section of the left frame shaft, positioning cards are provided at the front and rear ends of the left flat blade. The hole wall of the elongated hole in the middle section of the left frame shaft is inlaid with anti-friction balls or needle rollers to reduce the friction of the left flat blade moving in the hole. The rudder is arranged at the end of the propeller and mounted on the top plate. In order to prevent fish, weeds and other sundries in the water from entering the square pipe, a filter screen is installed at the front end of the square pipe.

The motor ship of the present invention works like this: the power of the engine is transmitted to the propeller through the transmission mechanism, and the hydraulic work station controls the hydraulic mechanism of the propeller. Under the joint action of the engine and the hydraulic workstation, the propeller works as follows: At first, the left and right flat blades are in the last position longitudinally, the hydraulic mechanism is in the longest state, and its rear end is located at the left and right flat blades behind the rear end. First, the hydraulic mechanism retracts forward, pulling the left flat blade and the right flat blade to the front position at the same time, and then the power is input from the upper end of the left frame shaft to drive the left frame shaft to rotate and drive the left flat blade to circle the left frame shaft in the square tube After the axis rotates counterclockwise for half a circle, it stops longitudinally at the rear. At the same time, the power is transmitted to the right frame shaft through the gear set. The rotation of the right frame shaft drives the right flat blade to rotate clockwise around the axis of the right frame shaft for half a circle in the square tube and stops longitudinally at the rear. , during the synchronous reverse rotation of the left flat blade and the right flat blade just now, the hydraulic mechanism also stretches backward at the same time, and the rear end of the hydraulic mechanism has reached the left flat blade when the left flat blade and the right flat blade turn to the final position and the back of the rear end of the right flat blade; then the left frame shaft and the right frame shaft stop rotating, and the hydraulic mechanism starts to pull the flat blade and the right flat blade straight forward to the frontmost position; then the hydraulic mechanism stretches backwards, and at the same time The power drives the left frame shaft and the right frame shaft to rotate, and then drives the left flat analysis blade and the right flat blade to rotate counterclockwise and clockwise for half a circle to the final position. At this time, the rear end of the hydraulic mechanism has reached the rear end and returned to the initial state. . Then continue to repeat the above process, and start again and again. The left flat blade and the right flat blade will continuously introduce the water in the front into the square pipe and then extrude it from the rear to generate forward thrust. During the movement, the front left flat blade and the right flat blade are quickly opened and the rear left flat blade and the right flat blade are quickly closed, resulting in the "snap" and "sumo" movement effects similar to insects. And due to the restraint of the square tube, the movement of the left flat blade and the right flat blade in the square tube also produces a mirror effect, which can produce a large thrust to make the motor ship advance. Changing the deflection angle of the rudder allows the motor boat to turn.

In order to facilitate the flexible movement of the left flat blade and the right flat blade in the square tube and work efficiently, the heights of the left flat blade and the right flat blade are slightly smaller than the distance between the lower surface of the top plate and the upper surface of the bottom plate of the square tube; The sum of the widths of the blade and the right flat blade is slightly smaller than the distance between the right side of the left side of the square tube and the left side of the right side; The frame shaft and the right frame shaft should be installed as close as possible.

A hydraulically reset double-screw motor ship of the present invention includes but is not limited to the following advantages: small energy loss, high efficiency, and easy fabrication of blades, which does not produce obvious wakes like propeller ships, and does not have serious wakes like traditional paddle ships. Due to the symmetrical layout of the double blades of the propeller, the rotational torque can be offset by each other, and the operation is stable.
