Description

A circular flat blade ship with a linear motor

technical field

The utility model relates to an annular flat blade ship with a linear motor, which belongs to the technical field of water transportation equipment, and in particular relates to a ship.

Background technique

Most traditional ship propellers use 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 water enters and before the water exits, the water resistance is large and the thrust generated 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. Traditional power ships are powered by a single diesel engine, and the tail is equipped with a rudder with a complex structure, which is inconvenient to travel backwards.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned technical deficiencies of traditional ships, and to invent a highly efficient annular flat-blade ship with a linear motor that can retreat without a rudder.

An annular flat-bladed ship with a linear motor comprises a hull, a left engine, a right engine, a left propeller and a right propeller. The left and right engines are the same. The left and right engines are controlled separately. The power of the left engine and the right engine is transmitted to the left propeller and the right propeller respectively through the transmission mechanism. The left propeller and the right propeller have the same structure, and they are symmetrically arranged on the left and right sides of the stern. The right propeller includes a main shaft, a turntable, an annular plate blade, a draw bar, a positioning bar and a casing. The annular flat plate blade comprises identical arc-shaped bodies at two ends and two identical flat plates parallel to each other in the middle section. The gap between the two plates of the annular flat blade is slightly greater than the sum of the diameters of the positioning rod and the draw rod, the height of the positioning rod is greater than two-thirds of the height of the annular flat blade, and the height of the draw rod is greater than that of the annular flat blade. three-fifths of the height. The thickness at the maximum thickness of the arc body at both ends of the annular flat blade is equal to or slightly smaller than the sum of the diameter of the drawbar and the thickness of a flat plate of the annular flat blade. The casing includes a left side plate, a bottom plate and a right side plate, the left side plate and the right side plate are vertically arranged, and the bottom plate is arranged horizontally. The positioning rod is vertically arranged in the middle of the front and rear direction of the casing and installed on the bottom plate near the left side plate. The gap between the positioning rod and the left side plate is slightly larger than the sum of the diameter of the draw bar and the thickness of a flat plate of the annular flat blade. , and can ensure the flexible semi-circular movement of the annular flat blade in the shell. The annular flat blade is set on the positioning rod and is located inside the casing, and the annular flat blade is perpendicular to the bottom plate of the casing. The turntable is horizontally arranged above the flat blades, and a linear motor is installed on the turntable. A linear motor consists of a stator and a mover. The upper end of the draw bar is installed on the mover, the draw bar is vertically arranged, and the lower section of the draw bar is inserted into the annular flat plate blade. The main shaft is installed in the center of the turntable, and the main shaft is arranged vertically above the turntable, and is mounted on a support connected to the stern through bearings.

The working principle of a ship with a linear motor with annular flat blades of the present invention: the right propeller works like this: at first, the annular flat blades are at the most forward position in the longitudinal direction, that is, the inner wall of the rear end of the annular flat blades is close to the trailing edge of the positioning rod, The front end of the annular flat blade is at the front end, and the left side of the annular flat blade is close to the right side of the left plate of the shell. The active force driving the right propeller is input from the upper end of the main shaft, and the right propeller is viewed from top to bottom. The main shaft drives the turntable to rotate clockwise. Since the drawbar is inserted into the annular flat blade, the mover of the linear motor drives the drawbar to make a reciprocating linear motion on the turntable. The shell makes a semi-circular motion, that is, the annular flat blade rotates half a circle around the positioning rod at the longitudinal front position and reaches the longitudinal final position, and then moves forward in a straight line to the longitudinal front position, and then the annular flat blade rotates clockwise around the positioning rod for half a circle, and then Go straight ahead to the vertical most forward position again, promptly got back to initial position. Then continue to repeat the above process periodically. In this way, the annular flat plate blades will continuously introduce the water in the front of the shell and then draw it to the rear to generate forward thrust. During the movement, the ring-shaped flat blades quickly open between the front and the left side panel of the shell and quickly close between the rear and the left side panel, producing the "jittery" and "sumo" movement effects similar to insects, and Due to the restraint of the casing and the turntable, the movement of the ring-shaped flat blades in the casing also produces a mirror effect, which can generate a large thrust. The blade of the left propeller makes a semi-circular motion counterclockwise. The reverse rotation of the left propeller and the right propeller can cancel each other out the torque. Said ship runs smoothly. When the rotation speed of the left and right propellers is different, the ship will turn and drive. If the blades of the left propeller turn clockwise and the blades of the right propeller turn counterclockwise, the ship will travel backwards.

The ship of the present invention includes but is not limited to the following advantages: small energy loss, high efficiency, and the blades are easy to manufacture, and will not produce obvious wakes like propeller propellers, nor will there be serious water splashing like traditional paddle wheel propellers . It is easy to drive forward and backward, and no rudder is needed.
