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 propulsion device, 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 propulsion technology, and to invent a high-efficiency internal tooth meshing plate paddle ship propulsion device with guide wheels.

A ship propulsion device with internal teeth meshing flat paddles with guide wheels, including a main shaft, gears, toothed annular flat paddles, a casing and a filter screen. The casing includes a left side board, a bottom board, a right side board and a top board, the left side board is vertically arranged, the right side board is parallel to the left side board, and the top board and the bottom board are arranged horizontally. The main shaft is vertically arranged on the right side of the left side plate of the casing, and the upper and lower ends of the main shaft are respectively installed on the top plate and the bottom plate through bearings, and the main shaft can rotate flexibly. Gears are mounted on the main shaft. The toothed annular flat paddle includes two parallel flat plates in the middle section and semicircular arc bodies at both ends. The inner circumference of the toothed annular flat paddle has a ring of teeth that can mesh with the gear. The toothed annular flat paddle is installed on Inside the shell and set on the main shaft. The teeth of the gear near the left plate mesh with the teeth of the toothed annular flat paddle. The maximum outer diameter of the gear is slightly smaller than the distance between the tooth tips on two parallel flat plates of the toothed annular flat paddle. Guide wheels are respectively installed on the bottom and the top of the semicircular arc-shaped body at both ends of the toothed annular flat paddle. An upper guide rail is installed on the lower surface of the top plate of the shell, and a lower guide rail is correspondingly installed on the upper surface of the bottom plate. The upper guide rail and the lower guide rail have the same outer circumference size and contour, and both are semicircular. The role of the upper guide rail is to restrict the two guide wheels installed on the top of the toothed annular flat paddle to move only outside the contour of the upper guide rail. Except for the area near the main shaft, the two guide wheels on the top of the toothed annular flat paddle at other positions The guide wheel rolls along the outer circumference of the upper guide rail; the function of the lower guide rail is to restrict the two guide wheels installed at the bottom of the toothed annular flat paddle to only move outside the contour of the lower guide rail. Except for the area near the main shaft, other positions are toothed. The two guide wheels at the bottom of the annular flat paddle roll along the outer periphery of the lower guide rail. The gap between the main shaft and the left side plate can ensure that the toothed annular flat paddle can move flexibly in a semi-circle in the housing, and when the toothed annular flat paddle moves straight forward, its left side always sticks to the right side of the left side plate noodle. In order to prevent sundries such as fish, aquatic plants and even silt from entering the housing, a filter screen is installed in front of the housing. The filter screen is placed obliquely in front of the shell, which is conducive to the sliding of sundries from the right side of the shell and is not easy to attach to the filter screen.

A kind of ship propulsion device with internal teeth meshing flat blades with guide wheels of the present invention produces beneficial effects like this: at first, the ring-shaped flat paddles with teeth are in the longitudinal frontmost position, that is, the rear end internal teeth of the ring-shaped flat paddles with teeth are in contact with the The gears are tightly meshed, the front end of the toothed annular flat paddle is at the forefront, and the left side of the toothed annular flat paddle is close to the right side of the left side plate of the shell. The power to drive the propulsion device is input from the main shaft, from the top Looking down at the propulsion device, the clockwise rotation of the main shaft drives the gear to rotate clockwise, and the gear drives the toothed annular flat paddle to make a clockwise half-circle movement in the housing, that is, the toothed annular flat paddle rotates half a circle around the main shaft at the longitudinal front position Finally, it reaches the final position in the longitudinal direction, and then moves straight forward to the front position in the longitudinal direction. Then, the toothed annular flat blade rotates clockwise for half a circle around the main shaft, and then moves forward in a straight line to the front position in the longitudinal direction, that is, it returns to the initial position. Next, the above process is repeated periodically. In this way, the toothed annular flat paddle will continuously introduce the water in the front of the shell and then draw it to the rear to generate forward thrust. During motion, the toothed ring-shaped flat paddle rapidly opens between the front and the left side panel of the housing and closes between the rear and the left side panel, creating insect-like "jiggling" and "sumo" movements Effect, and due to the limitation of the shell, the movement of the toothed annular flat blade in the shell also produces a mirror effect, which can generate a large thrust. Due to the limitation of the upper guide rail, lower guide rail and guide wheel, the toothed annular flat paddle can make a very standard semi-circular motion. The propulsion device of the present invention includes, but is not limited to, the following advantages: small energy loss, high efficiency, and easy manufacture of blades, which does not produce obvious wakes like propeller propulsion devices, and does not have serious splashing like traditional paddle wheel propulsion devices Phenomenon.

In order to make the efficiency of the propulsion device higher, the ratio of the aspect ratio of the toothed annular flat blade is between 0.8 and 4.

In order to reduce the friction between the bottom of the toothed annular flat paddle and the upper surface of the lower guide rail when the toothed annular flat paddle moves in the housing, the bottom of the toothed annular flat paddle is inlaid with anti-friction balls; the toothed annular flat paddle The density of the paddle is slightly higher than that of water, and its range is between 1050~1300kg/m ³ .

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

In order to prevent sundries from entering the shell, a filter screen is also arranged at the rear of the shell.

In order to achieve high efficiency and energy saving, the structure of the propulsion device should be compact in design, and the width of the toothed annular flat plate blade is slightly smaller than the distance between the right side of the left side plate of the shell and the left side of the right side plate; the toothed annular flat plate The height of the paddle is slightly smaller than the distance between the lower surface of the upper guide rail and the upper surface of the lower guide rail.

The casing 6 includes a left side plate 61, a bottom plate 62, a right side plate 63 and a top plate 64, the left side plate 61 is arranged vertically, the right side plate 63 is parallel to the left side plate 61, and the top plate 64 and the bottom plate 62 are arranged horizontally. The main shaft 1 is vertically arranged on the right side of the left side plate 61 of the casing 6, and the upper and lower ends of the main shaft 1 are respectively mounted on the top plate 64 and the bottom plate 62 through bearings, and the main shaft 1 can rotate flexibly. Gear 2 is mounted on main shaft 1. The toothed annular flat paddle 3 includes two parallel flat plates in the middle section and semicircular arc bodies at both ends. The inner circumference of the toothed annular flat paddle 3 has a circle of teeth that can mesh with the gear 2. The toothed annular flat paddle The leaf 3 is installed in the casing 6 and is sleeved on the main shaft 1 . The teeth of the gear 2 near the left side plate 61 mesh with the teeth of the toothed annular flat paddle 3 . The maximum outer diameter of the gear 2 is slightly smaller than the spacing between the tooth tips on two parallel flat plates of the toothed annular flat paddle 3 . The bottom and the top of the semicircular arc-shaped body at the two ends of the toothed annular flat blade 3 are respectively equipped with guide wheels 9. The upper guide rail 51 is installed on the lower surface of the top plate 64 of the housing 6 , and the lower guide rail 52 is installed on the upper surface of the bottom plate 62 correspondingly. The upper guide rail 51 and the lower guide rail 52 have the same outer circumference size and contour, and both are semicircular. The function of the upper guide rail 51 is to restrict the two guide wheels 9 mounted on the top of the toothed annular flat paddle 3 to move only outside the outline of the upper guide rail 51. Except for the area near the main shaft 1, other positions of the toothed annular flat paddle The two guide wheels 9 at the top of 3 roll along the outer circumference of the upper guide rail 51; Movement, except the vicinity of the main shaft 1, the two guide wheels 9 at the bottom of the toothed annular flat paddle 3 in other positions roll along the periphery of the lower guide rail 52. The gap between the main shaft 1 and the left side plate 61 can ensure that the toothed annular flat paddle 3 can move flexibly in a semi-circle in the housing 6 and that the toothed annular flat paddle 3 moves forward in a straight line. The left side sticks to the right side of the left side plate 61 all the time. In order to prevent sundries such as fish, aquatic plants and even silt from entering the shell 6, a filter screen 7 is installed at the front end and the rear end of the shell 6. In order to reduce the friction between the bottom of the toothed annular flat paddle 3 and the upper surface of the lower guide rail 52 when the toothed annular flat paddle 3 moves in the housing 6, the bottom of the toothed annular flat paddle 3 is inlaid with antifriction balls . The density of the toothed annular plate paddle 3 is the same as or slightly greater than that of water. The ratio of the height to the width of the toothed annular flat paddle 3 is 1.5:1.

The propulsion device works like this: at first, the toothed annular flat paddle is in the longitudinal frontmost position, that is, the rear end internal teeth of the toothed annular flat paddle 3 are tightly meshed with the gear 2, and the front end of the toothed annular flat paddle 3 At the front end, the left side of the toothed annular flat paddle 3 is close to the right side of the left side plate 61 of the casing 6, and the power for driving the propulsion device is input from the upper end of the main shaft 1, and the propulsion device is viewed from top to bottom , the main shaft 1 rotates clockwise to drive the gear 2 to rotate clockwise, and the gear 2 drives the toothed annular flat paddle 3 to make a clockwise semi-circular motion in the housing 6, that is, the toothed annular flat paddle 3 rotates around the main shaft 1 at the longitudinal front position After half a circle, it reaches the final longitudinal position, and then advances straight to the longitudinal front position. Next, the toothed annular flat paddle 3 rotates clockwise around the main shaft 1 for half a circle, and then moves straight forward to the longitudinal front position, that is, it returns to the initial position. Next, the above process is repeated periodically. In this way, the toothed annular plate paddle 3 can continuously introduce the water in the front into the casing 6 and then draw it to the rear to generate forward thrust. During the movement, the toothed annular flat paddle 3 is quickly opened between the front and the left side plate 61 of the housing 6 and quickly closed between the back and the left side plate 61, resulting in "snap" and "snap" similar to insects. "Sumo" movement effect, and due to the limitation of the shell 7, the movement of the toothed annular flat paddle 3 in the shell 6 also produces a mirror effect, which can produce a large thrust. Due to the limitation of the upper guide rail 51, the lower guide rail 52 and the guide wheel 9, the toothed annular flat paddle 3 can move in a very standard semicircle. The propulsion device has high efficiency.

When the motion direction of the toothed annular flat paddle 3 is counterclockwise, the propulsion device of the present invention can make the ship retreat.

If the aspect ratio of the toothed annular plate blade 3 is increased, the propulsion efficiency will be higher.
