Spherical water sports device with adjustable center of buoyancy and center of gravity

Abstract

The invention discloses a spherical water sports device with an adjustable center of buoyancy and center of gravity. The spherical water sports device comprises an outer spherical shell. The outer spherical shell is internally provided with an inner spherical shell in a sleeving mode, and a water storage bin is arranged in the middle of the outer spherical shell. The inner spherical shell and theouter spherical shell are fixedly connected through a spherical shell connecting module. A horizontal rotating shaft is connected to the inner wall of the inner spherical shell. A rotating motor is connected to one end of the rotating shaft, and a drive control box is fixedly connected to the middle of the rotating shaft. A first lead screw module and a second lead screw module are connected to the lower part of the drive control box separately, and a horizontal third lead screw module is slidably connected between the first lead screw module and the second lead screw module. The third lead screw module is provided with a power supply box and a counterweight block. Three driving units are controlled by a drive motor to change the position of the center of gravity of the spherical water sports device, so that the spherical water sports device rotates under the combined action of an eccentric moment and an inertia moment to achieve water sports. Both the position of the center of gravityand the position of the center of buoyancy of the spherical water sports device can be controlled and adjusted, so that good movement flexibility and high stability are achieved.

Description

technical field [0001] The invention relates to a water sports device, in particular to a spherical water sports device with an adjustable center of buoyancy and gravity, and belongs to the technical field of spherical robot equipment. Background technique [0002] A spherical motion robot is an independent moving body with a spherical or approximately spherical shell, and its movement method is mainly rolling. This type of robot has unique advantages when turning, and it has better flexibility than other movement modes. At the same time, due to its high geometric symmetry, the spherical device can quickly adjust the operating state, has a strong recovery ability, and can be well adapt to the environment. At the same time, due to the relatively small rolling resistance of the ball, the spherical robot has high motion efficiency and low energy consumption. The driving principle of the spherical robot can be divided into two types. One is that the driving unit is in direct c...
