Contents of the invention

The purpose of the present invention is to provide a high-efficiency ship propulsion device, which directly drives the flat paddles by circular motion power, which is energy-saving, high-efficiency, and simple in structure. Using two or more of the devices on the same ship can produce a flat paddle ship with high efficiency, energy saving, simple structure, safety and reliability.

The technical scheme adopted in the present invention is: the device is mainly composed of a rotating arm and its rotating arm shaft, a flat blade traction shaft, a flat blade, a flat blade guide frame and its rotating frame shaft and a fixed plate, etc., the rotating arm One end is fixedly connected with the shaft of the rotating arm, the shaft of the rotating arm is loosely installed on the frame, the traction shaft of the flat blade is installed on the other end of the rotating arm, the traction shaft of the flat blade is parallel to the shaft of the rotating arm, and one end of the flat blade is connected to the flat On the blade traction shaft, the other end of the flat blade passes through the flat blade guide frame. There is a rectangular hole in the central area of the plate, which is slightly larger than the plate blade guide frame, so that the plate blade guide frame can rotate in the hole. The fixed plate is perpendicular to the rotation plane of the rotating arm and is consistent with the front and rear direction of the ship. When the device of the present invention is used on a ship, the fixing plate is fixedly connected with the ship body and is parallel to or overlaps with the longitudinal symmetrical plane of the ship body.

The relevant components of the device of the present invention meet the following size conditions: the distance from the shaft of the rotating frame to the shaft of the rotating arm is slightly greater than the sum of the length of the rotating arm plus half the width of the guide frame of the flat paddle, and is as close as possible to the sum, but cannot affect the flat paddle The flexible rotation of the guide frame and the flexible sliding of the flat paddle in the flat paddle guide frame; the length of the flat paddle is slightly greater than the distance from the rotary frame axis to the boom axis, the length of the rotary arm and half the width of the flat paddle guide frame The sum of the two, and when the flat blade traction shaft turns to the farthest edge from the flat blade guide frame, it is advisable that the end of the flat blade through the flat blade guide frame just exposes the flat blade guide frame.

Turning the engine drives the rotating arm to rotate, and the rotating arm drives the traction shaft of the flat paddle to make a circular motion around the shaft of the rotary arm. Due to the constraint of the guide frame of the flat paddle, the flat paddle makes a circular motion at the lower end of the traction shaft of the flat paddle. The other end of the flat paddle makes a similar circular motion, and the middle section of the flat paddle moves back and forth in the flat paddle guide frame, and the flat paddle moves like an "8" shape, and the flat paddle is on the left and right sides of the flat paddle guide frame. Both sides produce a paddling effect. Under the condition of satisfying the above-mentioned component size, the backward stroke effect of the flat paddle is far greater than the forward stroke effect. When this device is used on a ship, the flat paddle can continuously generate a large thrust, coupled with the function of the fixed plate, the flat paddle The paddle can produce a motion effect similar to the "sumo and jerk" of insects, and the flat paddle is more efficient.

The advantages of the present invention are: it can be directly driven by the rotating engine after deceleration, and the structure is simple; under the traction of the flat paddle traction shaft and the constraint of the flat paddle guide frame, the flat paddle moves like an "8", and due to the fixed plate Together with the flat paddles, the device of the present invention can continuously generate greater thrust, and the efficiency of the flat paddles is extremely high; the paddles are flat and easy to manufacture.

Detailed ways

The structural principle and working principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to Fig. 1 and Fig. 2, a high-efficiency ship propulsion device of the present invention is mainly composed of a rotating arm 1 and its rotating arm shaft 2, a flat blade traction shaft 3, a flat blade 4, a flat blade guide frame 5 and its rotating frame shaft 6 and fixed plate 7 to form. One end of the rotating arm 1 is fixedly connected with the rotating arm shaft 2, the rotating arm shaft 2 is loosely installed on the frame, the flat paddle traction shaft 3 is installed at the other end of the rotary arm 1, the flat paddle traction shaft 3 and the rotary arm shaft 2 Parallel, the right end of flat paddle 4 is connected on the flat paddle traction shaft 3, and the left end of flat paddle 4 passes through flat paddle guide frame 5, and the rotating frame shaft 6 of flat paddle guide frame 5 is installed in fixed On the plate 7, the rotating frame shaft 6 is perpendicular to the rotating plane of the rotating arm 1, and there is a rectangular hole in the central area of the fixed plate 7, which is slightly larger than the flat paddle guide frame 5, so that the flat paddle guide frame 5 is conveniently placed in the hole. Swiveling, the fixed plate 7 is perpendicular to the rotation plane of the rotating arm 1, and is consistent with the front and rear direction of the ship. The distance from the rotating frame shaft 6 to the rotating arm shaft 2 is slightly greater than the sum of the length of the rotating arm 1 plus half the width of the flat blade guide frame 5, and is as close as possible to this sum, but it cannot affect the flexible rotation of the flat blade guide frame 5 and the flexible sliding of the flat paddle 4 in the flat paddle guide frame 5; the length of the flat paddle 4 is slightly larger than the distance from the rotary frame shaft 6 to the boom shaft 2, the length of the rotary arm 1 and half of the flat paddle guide frame 5 The sum of the three widths, and when the flat paddle traction shaft 3 is turned to the farthest side from the flat paddle guide frame 5, one end of the flat paddle 4 passing through the flat paddle guide frame 5 just exposes the flat paddle guide Box 5 is appropriate. When the device is used on a ship, the fixing plate 7 is fixedly connected with the hull and is parallel to or overlaps with the longitudinal symmetrical plane of the hull.

The power of the rotating engine is transmitted to the rotating arm shaft 2 through deceleration to drive the rotating arm 1 to rotate clockwise. Constrained by the paddle guide frame 5, the right end of the flat paddle moves in a clockwise circular motion under the traction of the flat paddle traction shaft 3, and the left end of the flat paddle 4 performs a counterclockwise similar circular motion, and the middle section of the flat paddle 4 is in the Flat paddle blades move back and forth in the guide frame 5.

Now, a motion cycle is divided into two processes for specific description:

Process 1. Initially, when the flat paddle 4 is just at the tangent position to the left front part of the large dotted line circle on the right side in Fig. 1, the rotating arm 1 starts to rotate clockwise under the drive of the power. The space between the part on the right side of the plate blade guide frame 5 and the right side of the front half of the fixed plate 7 of the flat paddle 4 widens to form a low-pressure zone, which sucks water to generate forward thrust; when the flat paddle 4 After running to the position parallel to the cross-section of the hull for the first time, as the rotating arm 1 continues to rotate, the space between the part on the right side of the flat blade guide frame 5 and the right side of the rear half of the fixed plate 7 Narrowing, the water flow between the two is extruded downwards, also produces forward thrust, until the flat paddle 4 just arrives at the tangent position with the left rear part of the large dotted line circle on the right side in Fig. 1, the greater half During the movement cycle, the flat paddle 4 shows different stroke effects on the left and right sides of the fixed plate 7, the flat paddle 4 on the right side of the fixed plate 7 strokes backward, and the flat paddle 4 on the left side of the fixed plate 7 4 Although the water is drawn forward, because the relevant components in the device of the present invention meet the aforementioned size conditions, the volume of water swept by the flat paddle 4 on the right side of the fixed plate 7 is much larger than that swept by the flat paddle 4 on the left side of the fixed plate 7 The volume of the water, so in the movement process, the force generated by the backward stroke of the flat blade 4 on the right side of the fixed plate 7 is far greater than the forward stroke convection of the flat blade 4 on the left side of the fixed plate 7 The active force of aquatic products, therefore, the resultant force that flat blade 4 produces in this process moves forward.

Process 2: When the flat paddle 4 is tangent to the left rear part of the large dotted line circle on the right side in Fig. 1, the rotating arm 1 continues to rotate clockwise under the drive of power, , the space between the left part of the flat paddle 4 on the left side of the flat paddle guide frame 5 and the left side of the front half of the fixed plate 7 is widened, which also forms a low-pressure zone, which sucks water into people, thereby generating forward thrust; when the flat paddle After the blade 4 moves to the position parallel to the cross-section of the hull for the second time, as the rotating arm 1 continues to rotate, the flat paddle 4 is between the left side of the flat paddle guide frame 5 and the left side of the rear half of the fixed plate 7. The space between the two is narrowed, and the water flow between the two is squeezed out downwards, which also produces a forward thrust until the flat paddle 4 just arrives at a position tangent to the left front part of the large dotted line circle on the right side in Fig. 1. At this time The flat paddle 4 has returned to the initial position of the process one. In this small half movement cycle, the flat paddle 4 also shows different stroke effects on the left and right sides of the fixed plate 7, and the flat paddle on the left side of the fixed plate 7 4. Swipe water backwards. Although the flat blade 4 on the right side of the fixed plate 7 strokes forward, because the relevant components in the device of the present invention meet the aforementioned size conditions, the flat blade 4 sweeps the water on the left side of the fixed plate 7. The volume is much larger than the volume of the water swept by the flat paddle 4 on the right side of the fixed plate 7, so in this movement process, the backward stroke of the flat paddle 4 on the left side of the fixed plate 7 exerts far more force on the flowing water. The forward stroke of the flat paddle 4 on the right side of the fixed plate 7 exerts an active force on the flowing water, so the resultant force produced by the flat paddle 4 in this process is also forward.

Generally speaking, under the driving of the rotating engine, such continuous movement, the flat paddle 4 is driven by the flat paddle traction shaft 3 driven by the rotating arm 1, and due to the constraint of the flat paddle guide frame 5, the flat paddle 4 does Like "8" shape movement, coupled with the role of the fixed plate 7, the flat paddle 4 can produce the motion effect of "sumo and jerk" similar to insects, can continuously generate greater thrust, and the efficiency of the flat paddle is higher . Reasonably balanced use of two or more of these devices will be able to produce a practical and efficient flat-panel blade ship.

The following example briefly illustrates the use of this high-efficiency ship propulsion device on a ship:

Example 1, using two identical devices of the present invention, looking down from the top of the hull, the left and right symmetrical arrangements of the two devices are arranged on both sides of the lower part of the hull, the rotating arms of the two devices are all close to the longitudinal symmetrical plane of the hull, the fixing of the two devices The plate is far away from the longitudinal symmetry plane of the hull and is fixedly connected with the fuselage and is parallel to the longitudinal symmetry plane of the hull. Driven by power, it rotates counterclockwise, and the two ship propulsion devices can be driven synchronously or independently, with good maneuverability.

Example 2, using three of these devices, looking down from the top of the hull, the three devices are arranged up and down in the middle and lower part of the stern of the hull, and the rotary frame shafts of their flat blade guide frames form a vertical line from top to bottom, and the three devices The fixed plate of the fixed plate is on the same plane and overlaps with the longitudinal symmetrical plane of the hull. The parameters of the upper and lower ship propulsion devices are the same. The rotating arms are arranged on the right side of the fixed plate. The installation direction of the ship propulsion device is opposite to that of the ship propulsion device above. The rotating arm is arranged on the left side of the guide frame of the flat blade. The rotating arm rotates counterclockwise under the drive of power, and the width of the flat blade of the middle ship propulsion device It is twice that of the above flat paddle, and other parameters are the same as above. The three ship propulsion devices can be driven in linkage or independently.
