Description

A kind of propulsion device for ships with semi-rotating annular flat blades with springs

technical field

The utility model relates to a ship propulsion device with semi-rotating annular flat blades with a spring, 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 traditional ship propulsion technology, and to invent a highly efficient semi-rotary annular flat blade ship propulsion device with springs.

The utility model relates to a ship propulsion device with a semi-rotating annular flat blade with a spring, which comprises a main shaft, a turntable, an annular flat blade, a drawing rod, a positioning rod, a casing and a filter screen. The annular flat plate blade comprises the same arc-shaped body at both ends and two identical flat plates in the middle section, and the thickness of the arc-shaped body is the same as that of the flat plate. 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 is slightly larger than the thickness of a flat plate forming the annular flat blade. The gap can ensure the flexible semi-circular movement of the annular flat blade in the casing. 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 guide rails, slide blocks and long springs are installed on the turntable. Sliders are mounted on rails. The long spring is set on the guide rail and is on the inner side of the slider. The upper end of the draw bar is installed on the slide block, the draw bar is vertically arranged, and the lower section of the draw bar is inserted in the annular flat plate blade. 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 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. The filter screen is installed in the front of the casing in a "herringbone" shape, and plays the role of filtering fish, weeds and other sundries. The "herringbone"-shaped filter screen is used to facilitate the debris to slide away to both sides of the propulsion device, so as not to stay in front of the shell and hinder water intake.

In order to prevent the rear end of the annular flat blade from hitting the positioning rod too hard due to poor size fit caused by machining errors, a short spring can be installed on the outside of the slide to play a buffer role, or at the end of the guide rail. A length-adjustable ejector rod or a rubber head can also act as a buffer instead of a short spring on the turntable.

A kind of half-rotating annular flat blade marine propulsion device with spring of the present invention produces beneficial effect like this: at first, annular flat blade is in the vertical most forward position, and the rear end inner wall of annular flat blade is close to the trailing edge of positioning rod, 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 casing, the power for driving the propulsion device is input from the upper end of the main shaft, and the propulsion device is viewed from top to bottom, the main shaft Drive the turntable to rotate clockwise, because the drawbar is inserted into the annular flat blade, the slider drives the drawbar to make a semi-circular motion, and at the same time drives the annular flat blade to make a semi-circular motion in the shell, that is, the annular flat blade circles the positioning rod at the frontmost position in the longitudinal direction After turning for half a circle, it reaches the final vertical position, and then moves straight forward to the longitudinal front position, and then the annular flat blade rotates clockwise for half a circle around the positioning rod, and then moves straight forward to the longitudinal front position, that is, it returns to the initial position. Next, 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.

The filter screen that prevents sundries such as fish and aquatic plants from entering the shell can also be placed in the front of the shell in a "one" shape.

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 2000kg/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, antifriction 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 make the annular flat blade move as standard as possible in a semicircle, a rail with a semicircular outer circumference is installed above the turntable, the rail is fixed on the bracket, and a guide wheel is installed directly above the slider, and the guide wheel follows the track The peripheral scrolling.

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 housing; 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, and the gap is between 2 and 5 mm.
