An underwater robot center of gravity adjustment device

Abstract

The invention provides a device for adjusting the gravity center of an underwater robot.The device comprises a shell rear end cover and a shell front end cover, the shell front end cover and the shell rear end cover are mounted on the front end face and the rear end face of a shell respectively, a glass front housing is mounted at the front end of the shell front end cover, the device further comprises a front support plate and a rear support plate, the front support plate is mounted at the rear side of the shell front end cover, the rear support plate is mounted at the front side of the shell rear end cover, the front end and the rear end of a screw rod are mounted on the front support plate and the rear support plate respectively, the front end of the screw rod is connected with a stepper motor through a synchronous wheel and a synchronous belt, a linear slide bar is mounted below the screw rod, a slide block is mounted on the screw rod, the linear slide bar penetrates through the slide block, a battery case is mounted at the lower end of the slide block, a balance weight tray is arranged at the outer side of a battery case body, and the battery case body is connected with the stepper motor through a spiral power line pipe.According to the device for adjusting the gravity center of the underwater robot, the battery case of the underwater robot is taken as a weight and mounted inside the gravity center adjusting device, and the device is compact in structure, convenient to install and capable of improving operation cruising power of the underwater robot.

Description

technical field [0001] The invention relates to a center-of-gravity adjusting device, in particular to an underwater robot center-of-gravity adjusting device. Background technique [0002] Underwater robot is an indispensable tool for modern ocean exploration and underwater operations. Underwater robots are often equipped with operating tools such as manipulators and dip nets, and carry cameras and various underwater equipment. With people's continuous exploration of oceans and lakes, and more and more applications in aquaculture The requirements for action completion and coordination when completing underwater operations are getting higher and higher, and the adjustment of the center of gravity of underwater robots is the key to completing various actions and maintaining the stability of the overall structure. [0003] At present, underwater robots generally have the problem that the center of gravity adjustment device takes up a lot of space. The way to adjust the center ...

Problems solved by technology

[0006] The Chinese patent document with the publication number CN104773272A discloses "a device for adjusting the center of gravity of an operating underwater robot". The deformation affects the transmission, and also reduces the diameter of the ball screw, reduces the weight of the system, and realizes the adjustment of the center of gravity of the underwater robot in the two directions of pitch and roll. However, the center of gravity adjustment device of the underwater robot still uses an additional To adjust the center of gravity, there is still a need to vacate a separate space for the battery, the battery capacity should not be too large, and the space utilization rate is not high.
