A half-rotating flat-plate ship propeller

technical field

A semi-rotary flat plate ship propeller belongs to the technical field of ships, in particular 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 the traditional ship propulsion technology, and to invent a semi-rotary flat ship propeller with higher efficiency.

The utility model relates to a semi-rotary flat-plate ship propeller, which includes a main shaft, a rotating disk, an annular flat-plate blade, a draw bar, a positioning bar, a casing, a filter screen and an energy storage mechanism. The annular flat plate blade comprises identical arc-shaped bodies at both ends and two identical flat plates in the middle section. The aspect ratio of the annular flat blade is between 2 and 3. The interior of the annular flat blade is a honeycomb structure, and the density of the annular flat blade is between 1000~2500kg/m ³ . 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 housing and fixedly installed on the bottom plate of the housing near the left side of the board. The gap between the positioning rod and the left side board can ensure that the annular flat blade can move flexibly 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 arranged horizontally above the flat-shaped blades, and there is a long hole on the turntable. Guide rails, sliders, long springs, short springs and spring support rods are installed in the long hole, and a pair of guide rails are fixed on the long strip. On the two long sides of the hole, the two sides of the slider cooperate with the guide rail. The spring supporting rod passes through the circular hole in the middle of the slide block, the two ends of the spring supporting rod are installed on the rotating disk, and the long spring and the short spring are sleeved on the spring supporting rod, and are respectively located on both sides of the sliding block. The short spring plays the role of cushioning and energy storage, so that the rear end of the annular flat blade will not be too violent when it hits the positioning rod; and some energy can be stored in the rear section of the annular flat blade to facilitate the positioning of the annular flat blade at the front. The stored energy is quickly released to the annular flat blades as the rod turns. The upper end of the drawbar is fixedly installed on the bottom surface of the slide block, the drawbar is arranged vertically, and the lower section of the drawbar is inserted into the annular flat blade. Rollers or bearings are sheathed around both the draw bar and the positioning bar. The main shaft is installed in the center of the turntable, the main shaft is arranged vertically above the turntable, and is installed on the bracket through the bearing. In order to prevent sundries such as fish and aquatic plants from entering the housing, a filter screen is installed in front of the housing. 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.

A kind of semi-rotating flat ship propeller of the present invention produces beneficial effect like this: At first, the annular flat blade is in the longitudinal most forward position, namely the rear end inner wall of the annular flat blade is close to the trailing edge of the positioning bar, and the front end of the annular flat blade is in the most forward position. At the front end, the left side of the annular flat blade is close to the right side of the left side plate of the casing, and 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 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 rotates half a circle around the positioning rod at the longitudinal front position to reach the longitudinal position. The final position, and then straight forward to the longitudinal front position, then the annular flat plate blade rotates clockwise half a circle around the positioning rod, and then straight forward to the longitudinal front position, that is, back 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 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.

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 be more efficient and energy-saving, an energy storage mechanism is installed on the left side of the left side plate. The function of the energy storage mechanism is to use the spring to store some energy when the annular flat blade moves forward in a straight line. When the positioning rod rotates, the stored energy is quickly released to compensate for the power at this time, so that the annular flat blade can be opened more quickly between the front and the left side plate of the shell, which can make the propulsion effect more obvious. The energy storage mechanism includes a roll spring, a swing rod and a swing angle limiter. The swing rod is placed in the gap between the turntable and the left side plate of the casing. One end of the swing rod is connected with the roll spring, and the roll spring is installed through a bracket. On the left side of the left side plate, the swing angle limit card is used to limit the swing angle range of the swing rod. The working principle of the energy storage mechanism is: when the annular flat blade is driven by the traction rod to move straight forward to the appropriate position, the traction rod touches the swing rod and then pushes the swing rod to deflect counterclockwise, the coil spring starts to store energy, and the draw rod moves forward When the coil spring reaches the front end, the energy storage of the coil spring ends, and then the energy storage mechanism releases the energy, the swing rod deflects clockwise, and the end of the swing rod away from the coil spring presses the drawbar, and the drawbar is under the joint action of the turntable and the swing rod Leaving the left side plate and revolving clockwise around the positioning rod along the arc line, it drives the annular flat blade to rotate clockwise around the positioning rod, and the annular flat blade quickly opens between the front and the left side board, producing a "snap" movement similar to insects effect, can produce a strong thrust.

The interior of the annular flat blade 3 is a honeycomb structure, and the density of the annular flat blade 3 is between 1000~2500kg/m ³ . The casing 6 includes a left side plate 61 , a bottom plate 62 and a right side plate 63 , the left side plate 61 and the right side plate 63 are vertically arranged, and the bottom plate 62 is arranged horizontally. Positioning rod 5 is vertically arranged in the middle part of the front and rear direction of casing 6 and is fixedly mounted on the bottom plate 62 of casing 6 near the side of left side plate 61, and the gap between positioning rod 5 and left side plate 61 can ensure that annular flat blade 3 The semi-circular movement is flexibly performed 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 there is a long hole on the turntable 2, and a guide rail 21, a slider 22, a long spring 23, a short spring 24 and a spring support rod 25 are installed in the long hole. A pair of guide rails 21 are fixed on the two long sides of the elongated hole, and the two sides of the slide block 22 cooperate with the guide rails 21 . The spring supporting rod 25 passes through the circular hole in the middle of the slide block 22, and the two ends of the spring supporting rod 25 are installed on the turntable 2, and the long spring 23 and the short spring 24 are sleeved on the spring supporting rod 25, and are placed on the sliding block 22 respectively. on both sides. The effect of long 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 as far as possible and go straight forward to the frontmost position. The short spring 24 plays a role of buffering and energy storage, so that the rear end of the annular flat blade 3 will not be too violent when it hits the positioning rod 5; When the most front rotates around the positioning rod 5, the stored energy is quickly released to the annular flat plate blade 3. The upper end of the draw bar 4 is fixedly installed on the bottom surface of the slide block 22 , the draw bar 4 is vertically arranged, and the lower section of the draw bar 4 is inserted in the annular flat plate blade 3 .
