Semi-submersible type intelligent robot for observing marine profile

Abstract

The invention discloses a semi-submersible type intelligent robot for observing a marine profile. The semi-submersible type intelligent robot comprises a float bowl, an underwater carrier, an anti-collision sonar, a height gauge, a battery compartment, a depthometer, a balance weight module, a control cabinet, a winch, an observation sensor, a propeller and vertical rudders, wherein the float bowlis connected with the underwater carrier by a fixed rod; the anti-collision sonar is arranged at the front part of the underwater carrier and horizontally faces forward; the height gauge and the depthometer are respectively arranged at the fore body and the middle part of the underwater carrier and both vertically face downward; the battery compartment, the balance weight module, the control cabinet and the winch are arranged in the underwater carrier; the propeller and the vertical rudders are arranged at the after body of the underwater carrier. The observation sensor is connected with thewinch by an armored cable and is fixed by a sensor locking sleeve and a pulley lock. The semi-submersible type intelligent robot disclosed by the invention is suitable for observing maritime characteristics of offshore and complex-environment sea area with vertical change distribution, such as thermocline, marine water body oxygen deficit and red tide.

Description

technical field [0001] The invention relates to a robot for ocean profile environment observation, in particular to a semi-submersible intelligent robot for ocean profile observation. Background technique [0002] Some phenomena in the ocean are not evenly distributed horizontally but also vertically, such as red tides and water hypoxia. In order to understand the causes of these ocean phenomena and carry out effective prevention and treatment, it is necessary to obtain observation data at different depths. The traditional methods are satellite remote sensing and buoys. The former can obtain large-area observation data, but only seawater surface data, and the resolution is low. The latter can obtain profile data, but only fixed-point observation data, and the coverage is small. . In recent years, the rapid development of underwater robot technology represented by AUV and underwater glider has been widely used in marine environment observation. AUV can sail at a fixed alti...

AI Technical Summary

Problems solved by technology

AUV can sail at a fixed altitude, fixed depth, and fixed speed, has little interference to the environment, and can obtain more accurate observation data, but it is not suitable for gliding up and down in the vertical plane. In addition, the offshore environment of our country is complex, especially the waste fishing nets affect the underwater The operation is safe, and the AUV cannot send the observation data to the monitoring center in real time underwater, and can only download the data after the observation task is completed and surfaced

Underwater gliders can glide in the vertical plane and surface regularly for data transmission. However, like AUVs, they also face the security threat of underwater fishing nets in offshore waters. At the same time, the depth of offshore waters ranges from a few meters to tens of meters, which is not suitable for the profile gliding motion of glider.
