The square pipe is surrounded by a left side board, a top board, a right side board and a bottom board. The left side plate and the right side plate of the square tube are vertically arranged, and the top plate and the bottom plate are arranged horizontally. The opening direction of the square pipe is the front-to-back direction. The left frame shaft and the right frame shaft have the same structure, they are symmetrically arranged vertically on the left and right sides of the middle of the square tube, and their respective upper and lower ends are respectively connected with the top plate and the bottom plate of the square tube through bearings. Gear set comprises left gear and right gear, and left gear and right gear are identical, and they are respectively installed in the upper end of left frame shaft and the upper end of right frame shaft. The left gear and the right gear are placed outside the square tube and positioned on the top of the square tube, and they are meshed with each other, and the transmission ratio of their meshing is 1:1. The left flat blade is the same as the right flat blade, they are all rectangular flat plates, their vertical side is the length direction, the side at the horizontal position is the width direction, and the ratio of their aspect ratio is between 1~3. The left flat blade and the right flat blade are installed symmetrically inside the square tube, they are all perpendicular to the bottom plate of the square tube, and they pass through the elongated holes in the middle section of the left frame shaft and the right frame shaft respectively. The rear end of the hydraulic mechanism is T-shaped, and the hydraulic mechanism is longitudinally installed between the left frame shaft and the right frame shaft. The hydraulic mechanism moves back and forth, and the effect of the hydraulic mechanism is to pull the left flat blade and the right flat blade from the rearmost position to the frontmost position. The power to drive the rotation of the left flat blade and the right flat blade is input from the upper end of the left frame shaft or the upper end of the right frame shaft.

First, the hydraulic mechanism retracts forward, pulling the left flat blade and the right flat blade to the front position at the same time, and then the power is input from the upper end of the left frame shaft to drive the left frame shaft to rotate and drive the left flat blade to circle the left frame shaft in the square tube After the axis rotates counterclockwise for half a circle, it stops longitudinally at the rear. At the same time, the power is transmitted to the right frame shaft through the gear set. The rotation of the right frame shaft drives the right flat blade to rotate clockwise around the axis of the right frame shaft for half a circle in the square tube and stops longitudinally at the rear. , during the synchronous reverse rotation of the left flat blade and the right flat blade just now, the hydraulic mechanism also stretches backward at the same time, and the rear end of the hydraulic mechanism has reached the left flat blade when the left flat blade and the right flat blade turn to the final position and the back of the rear end of the right flat blade; then the left frame shaft and the right frame shaft stop rotating, and the hydraulic mechanism starts to pull the flat blade and the right flat blade straight forward to the frontmost position; then the hydraulic mechanism stretches backwards, and at the same time The power drives the left frame shaft and the right frame shaft to rotate, and then drives the left flat analysis blade and the right flat blade to rotate counterclockwise and clockwise for half a circle to the final position. At this time, the rear end of the hydraulic mechanism has reached the rear end and returned to the initial state. . Then continue to repeat the above process, and start again and again. The left flat blade and the right flat blade will continuously introduce the water in the front into the square pipe and then extrude it from the rear to generate forward thrust. During the movement, the front left flat blade and the right flat blade are quickly opened and the rear left flat blade and the right flat blade are quickly closed, resulting in the "snap" and "sumo" movement effects similar to insects. And because of the shackles of the square tube, the movement of the left flat blade and the right flat blade in the square tube also produces a mirror effect, which can produce a large thrust.

In order to facilitate the flexible movement of the left flat blade and the right flat blade in the square tube and work efficiently, the lengths of the left flat blade and the right flat blade are slightly smaller than the distance between the lower surface of the top plate and the upper surface of the bottom plate of the square tube; The sum of the widths of the blade and the right flat blade is slightly smaller than the distance between the right side of the left side plate of the square tube and the left side of the right side plate; the left frame axis and the right frame axis are installed as close as possible.
