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. The robot comprises a spherical shell and an eccentric driving device, wherein the eccentric driving device can be rotationallyarranged in the spherical shell around an axis I, a certain distance is formed between the gravity center of the spherical shell and the axis I so as to generate eccentric moment for moving the underwater robot, and the axis I is collinear with the center of the spherical shell; the spherical shell comprises two semispherical shells and two semicircular ring hoops, flanges are connected at the openings of the semispherical shells, at least one circle of mounting grooves I close to the corresponding connecting flange are arranged on the outer wall of each semispherical shell, and the two semispherical shells are in sealing butt joint through the connecting flanges to form a sealing cavity capable of accommodating the eccentric driving device; the semicircular ring hoops are arranged in themounting grooves I in a mutual butt joint manner to fix the two semispherical shells; and the outer walls of the semispherical shells and the outer walls of the semicircular ring hoops are connected to form a complete spherical surface. The shell is simple and ingenious in structure and 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 ...
