Underwater unmanned cable-free operation type robot

Abstract

The invention relates to the technical field of underwater robots, and particularly relates to an underwater unmanned cable-free operation type robot which comprises a bow part, a middle part and a stern part. The bow part, the middle part and the stern part are each a hollow structure, and a mechanical arm lifting device and a cabin door opening and closing mechanism are arranged in the middle part; and a first horizontal channel propeller and a first vertical channel propeller are arranged on the bow portion, two second vertical channel propellers and four main propellers are arranged on the stern portion, and therefore high-speed cruising of the underwater unmanned cable-free operation type robot can be achieved, and stable and accurate hovering needed by operation of the underwater unmanned cable-free operation type robot can be met.

Description

technical field [0001] The invention relates to the technical field of underwater robots, in particular to an underwater unmanned and cable-free operation robot. Background technique [0002] Conventional unmanned unmanned underwater robot AUV can be mainly divided into the following two categories: monitoring type and operational type. Among them, the monitoring type underwater robot is mainly equipped with different sensors to directly measure related parameters, only for its own speed and battery life. The mileage and sensor installation position can be limited; the latter is affected by many factors such as its own endurance, its own stability and complex sea conditions, and there are few related products in the world. [0003] A monitoring robot such as the Chinese patent application number 202020449668.5 discloses an underwater robot for underwater detection. The vertical direction of the forward direction of the shell of the robot is thinner than the horizontal plane,...

AI Technical Summary

Problems solved by technology

[0005] The following focuses on the operational underwater robot. Since the AUV itself has its own energy, it must consider the energy saving and drag reduction of its shape. However, during the operation of the operational AUV, it needs to hover stably under complex sea conditions. resistance

[0006] The mechanical arm of the traditional operational AUV is directly installed on the outside of the body and close to the bow. Due to the complex structure of the mechanical arm itself, it is greatly affected by hydrodynamic forces as a whole, and the greater the speed, the greater the resistance, making it difficult to increase the cruising speed. also increases energy consumption

Therefore, the traditional operational AUV has poor battery life, insufficient operating range, and relatively high energy consumption.
