Problems solved by technology

Compared with underwater detection robots, frogman detection is not only low in detection efficiency but also high in cost, so it will inevitably be eliminated in the future market
[0003] At this stage, most of the underwater detection robots used in the market are wired connections, that is, the underwater detection robots are connected to the underwater detection robots with cables on the shore or by large ships, resulting in the invalid length of the cables being too long, which leads to the failure of the underwater detection robots. The activity flexibility is low, and the signal transmission distance is long
Although this method of wired connection with cables can ensure the effective transmission of data, due to the complex hydrological environment, the cables carried by underwater detection robots are easily entangled by passing ships or debris in the water, which affects detection efficiency and is easy to cause unnecessary economic loss
In addition, in the case of turbulent water flow, because the underwater detection robot itself lacks a positioning system in the horizontal direction and the cable is connected to the underwater detection robot in the water from the shore, the positioning of the underwater detection robot in the horizontal direction is not easy. Accurate, which in turn has a serious adverse effect on the detection process and recycling process

Abstract

The invention discloses an underwater detection device and a control method thereof, the device comprises a surface boat and an underwater unmanned aerial vehicle, and the surface boat comprises a boat body; the transverse stable attitude propeller and the orbit vector propeller are arranged at the bottom of the boat body; the control box is arranged on the boat body, and the transverse stable attitude propellers and the orbit vector propellers are electrically connected with the control box; the cable and the cable winding assembly are arranged on the boat body, the control box is connected with the underwater unmanned aerial vehicle through the cable, and the cable winding assembly is electrically connected with the control box; and the positioning assembly is arranged on the boat body and is electrically connected with the control box. The underwater structure is detected through cooperative operation of the surface boat and the underwater unmanned aerial vehicle, on one hand, the movement flexibility of the underwater unmanned aerial vehicle is improved, the signal transmission distance is reduced, and the underwater detection efficiency is improved; on the other hand, the underwater unmanned aerial vehicle can be positioned in the horizontal direction, and the positioning accuracy of the underwater unmanned aerial vehicle is improved. The method can be widely applied to the technical field of underwater detection.

Description

technical field [0001] The invention relates to the technical field of underwater detection, in particular to an underwater detection device and a control method thereof. Background technique [0002] There are many underwater facilities in my country and they have been used for a long time. According to the statistics of the Ministry of Communications, by the end of 2019, the total number of wading bridges in the country was 351,300. At the same time, 40% of the total number of bridges in my country has entered the aging period. In addition, the structural defect detection of underwater facilities such as docks, marine ranches, dams, water storage reservoirs, marine wind power generation facilities, water supply and drainage pipes, and immersed tunnels is also urgent. In this regard, detection agencies generally use frogmen or underwater detection robots to detect the width of underwater cracks. Compared with underwater detection robots, frogman detection is not only low i...
