The working principle of the specific embodiment is as follows:

referring to fig. 11, the placing direction and balance are adjusted in water:

after the propeller is placed in water, the propeller automatically floats on the water surface under the action of buoyancy because the cavity 15 of the propeller, the cavity of the blade-shaped balancer 16 and the embedded spiral blades 18 are arranged, and the top of the cavity 15 of the propeller is a cylindrical cavity structure 15-1 at the upper part and an inverted cone-shaped cavity structure 15-2 at the lower part, and the side wall is vertically designed along the circumference, so that the balance ball 19 entering the water body is in a motion state, cannot stay at the upper part of the cavity under the guidance of the inner wall structure of the cavity 15 of the propeller and finally stays at the bottom of the inverted cone-shaped cavity structure 15-2 at the lower part, and the balance ball 19 and the cavity 15 of the propeller jointly complete; meanwhile, as the whole propeller is designed in an axial symmetry manner, the boundary outside the blade-shaped balancer 16 acts with water flow in the position adjusting process, the downward blade profile generates upward thrust F1, the upward blade profile is smaller in area than the downward blade profile, and downward pressure F2 is generated under the action of the water flow, at the moment, F1 is greater than F2, the action lines of F1 and F2 are not over the center line of the propeller and are not collinear, two forces form rotating moments with different included angles with the shaft and different in magnitude in space, so that the low-speed rotation generated in the oblique direction of the propeller under the action of the two rotating moments creates conditions for downward movement of the balance ball 19 in the propeller cavity 15, and further accelerates the adjustment of the placement position of the propeller in water, namely the movement rules of the propeller cavity 15 and the balance ball 19 and the blade-shaped balancer 16 promote the position adjustment of the propeller, finally, the balancer stays at the bottom of the inverted cone-shaped cavity structure 15-2, and the structural design of the propeller keeps the transient balance of the propeller in water, and the propeller is not inclined and is placed in the forward direction; because the position of the blade-shaped balancer 16 is outside the cylindrical cavity structure 15-1, after the propeller is well adjusted in the fluid, the structure below the blade-shaped balancer 16 is completely immersed in the fluid, so that the overall balance of the propeller is enhanced;

referring to fig. 12, the water flow acts on the embedded helical blades, creating rotation and buoyancy:

the action of fluid on the embedded spiral blade 18 on the cavity 15 of the propeller is utilized, the horizontal component F3 generates a rotating moment along the tangential direction of the propeller, the action characteristic is that the rotating moment generates rotating mechanical energy to the propeller to enable the propeller to rotate on the water surface, the upward component F4 is the same as the placing direction of the propeller, the direction is parallel to the central axis of the propeller and vertically acts on the embedded spiral blade 18, and buoyancy is generated to match with the cavity 15 of the propeller and the cavity of the blade-shaped balancer 16 to improve the floating performance of the propeller; the change rule of the shape of the embedded spiral blade 18 outside the propeller cavity 15 enables the propeller to rotate more stably under the action of fluid;

referring to fig. 13, the wire is spun in water:

under the action of water flow, the embedded helical blade 18 on the propeller cavity 15 obtains a rotating moment, the external structure of the propeller forms a rotating motion, the propeller is integrally designed in an axial symmetry mode, the rotation of the propeller is influenced by factors such as the position and the size of the embedded helical blade 18, the size of the propeller, the geometric spatial arrangement and the dimensional relation of the leaf-shaped balancer 16 and the balance ball 19, and the like, a regulating cone 20 in the rotating propeller is asynchronous with the rotation of the rotating propeller due to the inertia effect, the winding operation is carried out by utilizing the asynchronous characteristic, namely, the lower end of a winding wire is led out downwards from the threading hole 3 and is tied on the wiring lug 9, the propeller is placed in water and floats on the water surface, the water flow has embedded impact force on the embedded helical blade 18, so that a certain force is applied to the embedded helical blade 18, and the helical blade 18 drives the propeller cavity 15 to rotate after, under the combined action of the balance ball 19 and the blade-shaped balancer 16 in the propeller cavity 15, the propeller keeps balance while rotating, eddy generated in the rotating process is eliminated, in the whole rotating process, the winding handle 2, the wire spool 6, the upper baffle 7, the lower baffle 8 and the wiring lug 9 are kept still, the propeller cavity 15 drives the winding to be wound on the wire spool 6 while rotating, the height of the adjusting cone 20 is adjusted by adjusting the cone flexible steel wire 21, and the sinking amount of the whole propeller in water is adjusted; when the angular speed W1 of the adjusting cone is not equal to the angular speed W2 of the gyroscope, the whole propeller achieves the winding function.

After adopting above-mentioned structure, this embodiment's beneficial effect is as follows:

1. the floating and balancing of the propeller are achieved by utilizing the cavity of the propeller, the cavity of the blade-shaped balancer and the embedded spiral blade;

2. the automatic adjustment of the balance placing position of the propeller is achieved by utilizing the movement of the cavity of the propeller and the balance ball;

3. the rotation of the propeller can be achieved by utilizing the mechanical energy of the water flow rotating the embedded spiral blade, and the buoyancy of the propeller is improved by utilizing the upward component force of the water flow to the embedded spiral blade;

4. the blade-shaped balancer is used for ensuring that the buoyancy of the propeller is enhanced, and the blade-shaped structure is favorable for forming a floating stable state;

5. the adjusting cone in the rotating propeller rotates asynchronously with the rotating propeller under the action of inertia, and the winding operation can be performed by utilizing the asynchronous characteristic.
