Detailed ways

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

With reference to Fig. 1, Fig. 2, a kind of square tube ship propulsion device of the present invention is mainly by rotating arm 1, rotating arm shaft 2, rotating arm shaft bearing 3, paddle traction shaft 4, traction shaft bearing 5, flat blade 6, paddle The leaf guide frame 7, the rotary frame shaft 8, the rotary frame shaft bearing 9, the middle partition plate 10 and the square tube 11 are composed. One end of the rotary arm 1 is fixedly connected with the rotary arm shaft 2, and the rotary arm shaft 2 is installed through the rotary arm shaft bearing 3. On the hull, the paddle traction shaft 4 is installed on the other end of the boom 1 through the traction shaft bearing 5, the paddle traction shaft 4 is parallel to the boom shaft 2, and one end of the flat paddle 6 is connected to the paddle traction shaft 4, The other end of the flat paddle 6 passes through the blade guide frame 7, and the blade guide frame 7 is loosely installed in the center of the middle partition 10 through the swivel frame shaft bearings 9 at both ends of the swivel frame shaft 8, and the swivel frame shaft 8 is connected to the swivel frame shaft. The rotation plane of arm 1 is vertical, and there is a rectangular hole in the central area of intermediate partition 10, and this hole is slightly larger than paddle guide frame 7, facilitates paddle guide frame 7 to swing in this hole, and intermediate partition 10 and rotating arm 1 The plane of rotation is vertical and consistent with the front and rear directions of the ship. The middle partition 10 is fixedly connected to the inside of the square tube 11, and the middle partition 10 is parallel to the left and right walls of the square tube 11. The square tube 11 is fixedly connected to the hull. 11 The opening direction is consistent with the forward direction of the ship.

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

Process 1. Initially, when the flat paddle 6 is just at the tangent position to the left front 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 power. The space between the part on the right side of the blade guide frame 7 of the flat blade 6 and the front half of the middle partition plate 7 widens to form a low-pressure zone, which sucks water to generate forward thrust, and the space on the right side of the square pipe 11 The mirror effect is produced under the action of the flat paddle 6, and the thrust generated by the flat paddle 6 is more obvious; The space between the part on the right side of the paddle guide frame 7 and the rear half of the middle partition plate 10 narrows, and the water flow between the two is extruded backwards, which also produces forward thrust, and on the right side of the square pipe 11 The mirror effect is produced under the action, and the thrust produced by the flat paddle 6 is also more obvious until the flat paddle 6 just arrives at the tangent position to the left rear part of the large dotted line circle on the right side in Fig. The flat paddle 6 shows different stroke effects on the left and right sides of the middle partition 10, and the flat paddle 6 on the right side of the middle partition 10 strokes backwards, while on the left side of the middle partition 10 the flat paddle Swipe forward, but because the relevant components in the device of the present invention meet the aforementioned dimensional conditions, the volume of water swept by the flat paddle 6 on the right side of the middle partition 10 is far greater than that swept by the flat paddle 6 on the left side of the middle partition 10 The volume of water, so in this motion process, the force that the paddle blade 6 strokes backward on the right side of the middle partition 10 on the flowing water is far greater than the forward stroke of the flat paddle 6 on the left side of the middle partition 10 The active force that water produces to flowing water, therefore, the resultant force that flat paddle 6 produces in this process moves forward.

Process 2: When the flat paddle 6 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 side of the blade guide frame 7 and the front half of the intermediate partition 10 of the flat paddle 6 widens, forming a low-pressure area, which sucks water in, thereby generating forward thrust, and the square pipe 11 The mirror effect is produced under the action of the left wall, and the thrust produced by the flat paddle 6 is more obvious; when the flat paddle 6 runs to a position parallel to the cross-section of the hull for the second time, as the rotating arm 1 continues to rotate, the flat paddle 6 6. The space between the left part of the blade guide frame 7 and the rear half of the intermediate partition 10 narrows, and the water flow between the two is extruded backward, which also generates a forward thrust, and on the left side of the square tube 11 The mirror effect is produced under the action of the wall, and the thrust produced by the flat paddle 6 is also more obvious until the flat paddle 6 just reaches the left front tangent position with the large dotted line circle on the right side in Fig. 1. At this time, the flat paddle 6 Returning to the initial position of process one, in the small half movement cycle, the flat paddle 8 also exhibits different stroke effects on the left and right sides of the middle partition 10, and the flat paddle 6 on the left side of the middle partition 10 After paddling, although the right side plate paddle 6 of the middle partition 10 strokes water forward, because the relevant components in the device of the present invention meet the aforementioned size conditions, the flat paddle 6 sweeps the water on the left side of the middle partition 10. The volume is far greater than the volume of the water swept by the flat paddle 6 on the right side of the middle partition 10, so the backward stroke of the flat paddle 6 on the left side of the middle partition 10 exerts far less force on the flowing water during this movement. Far greater than the force produced by the flat paddle 6 on the right side of the middle partition 10 when the water is stroked forward against the flowing water, therefore, the resultant force generated by the flat paddle 6 in this process is also forward.

Generally speaking, under the driving of the rotating engine, such continuous movement, the flat paddle 6 is driven by the blade traction shaft 4 driven by the rotating arm 1, and due to the constraint of the paddle guide frame 7, the flat paddle 6 is shaped like " 8" shape movement, coupled with the role of the middle partition 10 and the square tube 11, the flat paddle 6 can produce the movement effect and mirror effect similar to the "sumo and tension" of insects, and can continuously generate greater thrust. high efficiency.

The following example briefly illustrates the situation that the square tube ship propulsion device is used on a ship:

Example 1, use two devices of the present invention, two devices are symmetrically arranged on both sides of the hull bottom, the pivoting arms of the two devices are all close to the longitudinal symmetry plane of the hull, and the middle partitions of the two devices are away from the longitudinal symmetry plane of the hull, with The side wall of the square tube parallel to the intermediate partition and close to the propeller traction shaft is fixedly connected to both sides of the hull, and the side wall of the square tube is parallel to the longitudinal symmetrical plane of the hull, and the opening of the square tube is consistent with the forward direction of the ship. Looking down from the top of the hull, the rotating arm installed on the left side of the hull rotates clockwise under the drive of power, and the rotating arm installed on the right side of the fuselage rotates counterclockwise under the drive of power. When the left and right devices turn in the opposite direction and the speed is the same, the ship moves forward in a straight line; when the speed of one side decreases, the ship turns to this side; when both sides reverse at the same speed at the same time, the ship moves backward.

Example 2, using a device, the device is installed under the stern of the hull, the rotating arm of the device is close to the hull, the middle partition is arranged horizontally and away from the hull, and the square tube is parallel to the middle partition and close to the blade traction shaft The side wall is fixedly connected with the bottom of the hull, and the opening of the square pipe is consistent with the forward direction of the ship. Viewed from the left side of the hull to the right side, when the rotating arm of the device rotates clockwise under the drive of power, the ship moves forward, and when it is reversed, the ship moves backward. When using one of the devices, the ship should be equipped with a rudder.
