Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0045] Such as Figures 1 to 14 As shown, an improved spherical rolling underwater robot includes: a spherical shell and an eccentric drive device 3, and the eccentric drive device 3 is rotatably arranged in the spherical shell around the axis I100, and its center of gravity is in line with the described spherical shell. There is a certain distance between the axes I100, which are collinear with the center of the spherical shell, so as to generate an eccentric moment for moving the underwater vehicle. When the underwater robot moves forward or backward in the roll mode, the moving direction is perpendicular to the axis I100.

[0046] Such as figure 2 , Figures 8 to 13 As shown, the spheric...

Abstract

The invention discloses an improved spherical rolling underwater robot, comprising: a spherical shell and an eccentric drive device, the eccentric drive device is arranged in the spherical shell so as to be able to rotate around the axis I, and there is a certain distance between the center of gravity and the axis I Thereby can produce the eccentric moment that makes underwater robot move, axis I is collinear with the center of spherical housing; The outer wall of the hemispherical shell is provided with at least one installation groove I close to the connecting flange, and the two hemispherical shells are sealed and butted by the connecting flange to form a sealed cavity capable of accommodating the eccentric drive device; Two hemispherical shells are fixed in the installation groove I; the outer wall of the hemispherical shell and the outer wall of the semicircular hoop border and form a complete spherical surface. The housing of the invention has a simple and ingenious structure and is easy to install.

Description

technical field [0001] The invention belongs to the technical field of submersibles, and in particular relates to an improved spherical rolling underwater robot. Background technique [0002] As one of the main technological means for human beings to develop and utilize the ocean, submersibles have become an important frontier of marine high-tech. A large number of submersibles have emerged one after another, including manned submersibles (HOV), cable-operated remote-controlled unmanned vehicles (ROV), and cable-free autonomous unmanned submersibles (AUV). These submersibles, such as AUV, are most likely to cruise near the seabed or stand on standby, and cannot maneuver freely on the seabed, while those that can operate on the seabed, such as crawler ROVs, require surface power from umbilical cables. [0003] At present, multi-dwelling spherical submersibles capable of rolling and floating in water bodies have two-layer shells, the outer shell is a non-pressure-bearing and ...
