Description

An annular flat blade ship propeller with springs

technical field

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

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.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned deficiencies of traditional ship propulsion technology, and invent a kind of efficient ring-shaped plate blade ship propeller with springs.

The utility model relates to a ship propeller with a ring-shaped 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 identical arc-shaped bodies at both ends and two identical flat plates in the middle section. In order to make the propeller run smoothly and reliably, the gap between the two flat plates of the annular flat blade is slightly larger than the sum of the diameters of the positioning rod and the draw rod, and the height of the positioning rod is greater than two-thirds of the height of the annular flat blade , the height of the drawbar is greater than three-fifths 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, and the gap between the positioning rod and the left side plate is slightly larger than the diameter of the draw rod and a piece of the annular flat blade. The sum of the thicknesses of the plates and the gap between the positioning rod and the left side plate can ensure that the annular plate blades can flexibly move in a semi-circle in the housing. 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 springs are installed on the turntable. The slider cooperates with the guide rail. The spring is set on the guide rail and is on the inner side of the slider. The upper end of the drawbar is fixedly mounted on the bottom of the slide block, the drawbar is arranged vertically, and the lower section of the drawbar is inserted into 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. 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. The filter screen is in the shape of a "herringbone", which is conducive to the sliding of fish, aquatic plants and other sundries from the side of the shell, and is not easy to attach to the filter screen.

A kind of ring-shaped plate blade ship propeller with spring of the present invention produces beneficial effect like this: at first, the ring-shaped plate blade is in the vertical most forward position, and the rear end inner wall of the ring-shaped plate blade is close to the trailing edge of the positioning bar, and the ring-shaped plate blade The front end is at the forefront, and the left side of the annular flat blade is close to the right side of the left plate of the casing. The power to drive the propeller is input from the upper end of the main shaft. Looking down at the propeller from top to bottom, the main shaft drives the turntable Rotating clockwise, since the drawbar is inserted into the ring-shaped flat blade, the slider drives the drawbar to make a semi-circular motion, and at the same time drives the ring-shaped flat blade to make a semi-circular motion in the housing, that is, after the ring-shaped flat blade rotates half a circle around the positioning rod at the longitudinal front position Reach the final position in the longitudinal direction, and then move straight forward to the front position in the longitudinal direction, then the annular flat blade rotates clockwise for half a circle around the positioning rod, and then advances straight to the front position in the longitudinal direction, that is, it returns 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. If the power drives the ring-shaped flat blade to make a counterclockwise semi-circular movement in the casing, the propeller can make the ship retreat. The propeller includes, but is not limited to, the following advantages: low energy loss, high efficiency, and easy-to-fabricate blades, which do not produce obvious wakes like propeller propellers, and do not have serious water splashing like traditional paddle wheel propellers. Phenomenon, forward and backward are equally convenient.

In order to make the propeller more efficient, the ratio of the aspect ratio of the annular flat blade is between 1 and 3.

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 is placed on the bottom of the annular flat blade; the density of the annular flat blade is between 1300~2000kg/m ³ .

In order to reduce the friction between the drawing rod and the positioning rod and the inner surface of the annular flat blade, the surroundings of the drawing rod and the positioning rod are inlaid with anti-friction balls or needles or are sheathed with rollers or bearings.

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 propeller 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 housing 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.

The positioning rod 5 is vertically arranged, and the gap between the positioning rod 5 and the left side plate 61 is slightly larger than the drawbar. The sum of the diameter of 4 and the thickness of a plate of the annular flat blade 3, the gap between the positioning rod 4 and the left side plate 61 can ensure that the annular flat blade 3 can move flexibly in a semicircle in the housing 6. The annular flat blade 3 is sleeved on the positioning rod 5 and located inside the casing 6 , and the annular flat blade 3 is perpendicular to the bottom plate 62 of the casing 6 . The turntable 2 is horizontally arranged above the flat blade 3 , and a guide rail 21 , a slide block 22 and a spring 23 are installed on the turntable 2 . The slider 22 cooperates with the guide rail 21 . The spring 23 is sleeved on the guide rail 21 and is located inside the slider 22 . The effect of spring 23 is to make annular flat plate blade 3 can do standard semi-circular motion as far as possible, makes annular flat plate blade 3 be close to the right side face of left side plate 61 from the last position to move straight forward to the frontmost position as far as possible. The upper end of the draw bar 5 is fixedly mounted on the bottom of the slide block 22 , the draw bar 5 is vertically arranged, and the lower section of the draw bar 5 is inserted in the annular flat plate blade 3 . The main shaft 1 is installed in the center of the turntable 2, the main shaft 1 is arranged vertically above the turntable 2, and is mounted on a support through a bearing. In order to prevent sundries such as fish and aquatic plants from entering the shell 6, a filter screen 7 is installed in the front and rear of the shell 6.
