Problems solved by technology

However, the problem with this method is that it is difficult to control the water pressure. If the water pressure is too large, it will easily damage the wall; if the water flow is too small, the cleaning effect will not be ideal.

Embodiment 1

[0029] Such as figure 1 As shown, the present embodiment 1 provides an underwater unmanned aerial vehicle, comprising: a fuselage body 2 with four rotor blades 1, the fuselage body 2 carries a cleaning device 3, through which the cleaning device 3 is suitable for Clean the underwater scene.

[0030] The fuselage body 2 is provided with a processor module and a detection unit; wherein the detection unit includes a gyroscope, an acceleration sensor, a camera, an ultrasonic sensor and an infrared sensor connected to the processor module; and the processor module is also connected to the processor module. The quadrotor drive module is connected.

[0031] The processor module is suitable for identifying the pollutants attached to the underwater scene through the video data collected by the camera; the video data can also be sent to the upper computer for identification through wireless means, or manually identified.

[0032] The processor module is also suitable for avoiding the ...

Embodiment 2

[0041] On the basis of embodiment 1, this embodiment 2 also provides a working method of the underwater drone.

[0042] The working method of described underwater unmanned aerial vehicle comprises the steps:

[0043] Step S1, identifying pollutants attached to the underwater scene; and

[0044] Step S2, adjusting the posture to clean the pollutants.

[0045] Described underwater drone is as described in embodiment 1.

[0046]If a pothole area is identified, and pollutants are attached to the pothole area; the four-rotor blade 1 is suitable for controlling the fuselage body 2 to extend into the pothole area, and the processor module controls the cleaning device 3 along the guide rail 4 and in the pothole area The surface is washed back and forth, and while cleaning the surface of the pothole area, the four-rotor blade 1 is suitable for driving the fuselage body 2 to rotate at a constant speed, so as to form a spiral cleaning track in the pothole area and improve the cleaning ...

Abstract

The invention relates to a quadrotor structure based underwater detecting and cleaning unmanned aerial vehicle and a working method thereof. The unmanned aerial vehicle comprises a vehicle body with a quadrotor blade, wherein the vehicle body is provided with a cleaning device which is suitable for cleaning an underwater scene. According to the unmanned aerial vehicle and the working method of the unmanned aerial vehicle, a quadrotor structure of an unmanned plane is popularized to the underwater unmanned aerial vehicle, and besides, a gyroscope and an acceleration sensor are carried. The quadrotor structure based underwater detecting and cleaning unmanned aerial vehicle is higher in stability in underwater operation, the underwater condition can be accurately detected through a camera, an ultrasonic transducer and an infrared sensor, the underwater cleaning work is efficiently and stably completed, and compared with a traditional underwater robot, the underwater unmanned aerial vehicle is small in overall framework, low in cost and convenient to test.

Description

technical field [0001] The invention relates to an underwater detection and cleaning unmanned aerial vehicle based on a four-rotor structure and a working method thereof. Background technique [0002] Reservoir dams are important infrastructure for water conservancy to provide water security for national economic and social development. Submarine cable transmission projects and underwater oil pipeline construction are important components of cross-sea networking projects. Due to the harsh underwater environment, high degree of corrosion, and the age of the dam body, cracks have increased, multiple water seepage, strength reduction, and serious displacement of the dam have seriously threatened the safety of the dam. [0003] At present, there are two main methods for cleaning underwater structures such as dams: [0004] The first is traditional artificial cleaning. It is necessary to artificially carry out underwater detection in the absence of water, which is time-consumin...
