Adjust the placement direction and balance in the water: After the gyroscope is placed in the water, due to the cavity design of the gyro cavity (15) and the blade balancer (16), it automatically floats on the water surface under the action of buoyancy. It is a positive conical structure, the lower part is an inverted conical design, and the side wall is vertically designed along the circumference. After entering the water body, the balance ball is in a moving state. Guided by the inner wall structure of the gyro cavity (15), it cannot stay in the cavity. The upper part finally stays at the bottom of the inverted cone at the lower part of the cavity. The structure of the balance ball (20) and the gyro cavity (15) structure together completes the automatic adjustment of the position of the gyroscope on the water surface; at the same time, due to the axis of the gyro cavity (15) Symmetrical design, the outer boundary of the airfoil balancer (16) acts with the water flow during the process of adjusting the position of the gyroscope, the downward-facing airfoil surface generates upward thrust, and the area of the upward airfoil surface is larger than that of the downward-facing airfoil surface.

In addition, the action line of the upward thrust and the downward thrust is not the center line of the gyroscope and is not collinear. The two forces In space, rotational moments with different included angles and different sizes are formed with the axis. Therefore, under the action of these two rotational moments, the low-speed rotation in the tilting direction of the gyroscope is generated.

In the middle, the winding handle (2), the winding reel spool (6), the upper baffle (7), the lower baffle (8) and the wiring lug (9) remain stationary, and the gyro cavity (15) rotates at the same time. , which drives the winding to be wound on the bobbin (6) of the winding reel.
