Description

An annular flat blade ship propulsion device with a linear motor

technical field

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

Background technique

Most of the traditional ship propulsion devices use propellers. Although the drive is convenient, the efficiency is low. 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.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned deficiencies of the traditional ship propulsion technology, and to invent a high-efficiency annular flat-blade ship propulsion device with a linear motor.

A ship propulsion device with an annular flat blade with a linear motor, comprising a main shaft, a turntable, an annular flat blade, a traction rod, a positioning rod and a casing. The annular flat plate blade comprises identical arc-shaped bodies at both ends and two identical flat plates in the middle section. In order to make the efficiency of the propulsion device higher, reduce the thickness-to-width ratio of the annular flat blade as far as possible, the outer diameters of the draw bar and the positioning rod are the same, and the outer diameter of the positioning rod is slightly smaller than the gap between the two flat plates of the annular flat blade; The height of the positioning rod is slightly less than half of the height of the annular flat blade, and the height of the draw bar is slightly larger than half of the height 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 located in the middle of the front and rear direction of the casing and is installed on the bottom plate of the casing near the left side plate. The positioning rod is arranged vertically. The gap between the positioning rod and the left side plate can ensure that the annular flat blade can flexibly make a semicircle in the casing. weekly exercise. 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, the main shaft is vertically arranged above the turntable, and is installed on the support through bearings.

A kind of annular flat blade ship propulsion device with linear motor of the present invention produces beneficial effect like this: at first, the annular flat blade is in the vertical most forward position, and the rear end inner wall of the annular flat blade is close to the trailing edge of the positioning bar, and the annular flat blade The front end of the blade is at the front end, the left side of the annular flat blade is close to the right side of the left plate of the shell, and the active force for driving the propulsion device is input from the upper end of the main shaft. Looking down at the propulsion device from top to bottom, the main shaft Drive 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. Make a semi-circular motion inside, 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 again Go straight ahead to the longitudinal frontmost position, that is, return to the 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 propulsion device 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 the propeller propulsion device, and will not have serious splashing like the traditional paddle wheel propulsion device Phenomenon. If the power makes the annular flat blades move counterclockwise in a semi-circle, the device can make the ship retreat.

In order to prevent sundries such as fish and aquatic plants from entering the housing, filter screens are installed at the front and rear of the housing.

In order to make the efficiency of the propulsion device higher, the ratio of the aspect ratio of the annular flat blade is between 1 and 4.

In order to reduce the friction between the bottom of the annular flat blade and the upper surface of the bottom plate of the casing when the annular flat blade moves in the casing, the bottom of the annular flat blade is inlaid with anti-friction balls, or a wear-resistant flat gasket is placed on the positioning rod , the wear-resistant flat gasket is located on the upper surface of the bottom plate of the shell and pads on the bottom of the annular flat blade; the density of the annular flat blade is less than 1500kg/m ³ .

In order to reduce the friction between the draw bar and the positioning bar and the inner surface of the annular flat blade, anti-friction balls or needles are inlaid around the draw bar and the positioning bar, or rollers or bearings are set around the draw bar and the positioning bar .

In order to reduce the friction between the outer surface of the annular flat blade and the right side of the left side plate of the housing, the right side of the left side plate is inlaid with anti-friction balls or needles.

In order to achieve high efficiency and energy saving, the structure of the propulsion device is made compact, so that the width of the annular flat blade is slightly smaller than the distance between the right side of the left side plate of the casing and the left side of the right side plate; the height of the annular flat blade is slightly Less than the distance between the lower surface of the turntable and the upper surface of the bottom plate of the casing; the gap between the lower surface of the turntable and the left side plate and the right side plate should be as small as possible.
