Problems solved by technology

[0004] The purpose of the present invention is to propose a UAV for autonomous navigation in the furnace space, to solve the problem that the UAV cannot perform positioning and autonomous flight when the closed space in the prior art does not have satellite positioning signals, and the flight position is not accurate for the operator. The requirements are high, the operation effect is poor, and the aircraft does not have a protective structure. During the inspection process, there is a high probability of collision with obstacles, which leads to the problem that the drone cannot perform flight operations due to imbalance.

Embodiment 1

[0037] This embodiment proposes an unmanned aerial vehicle for autonomous navigation in the space in the furnace, such as Figure 1-8 As shown, the unmanned aerial vehicle for autonomous navigation in the furnace space includes a fuselage body 1 arranged in the middle and propeller devices 3 arranged at the four corners, and a laser radar positioning device 2 and a retractable assembly are arranged on the fuselage body 1 8. A protective structure 7 is set on the propeller device 3 , and the laser radar positioning device 2 is set above the fuselage main body 1 .

[0038] The laser radar positioning device 2 is set on the fuselage main body 1, so that the unmanned aerial vehicle in the space in the furnace can realize autonomous navigation and autonomous positioning flight; The function of the laser radar can reduce the influence of the laser occlusion angle of other devices, so that a larger data range information can be collected, thereby improving the positioning accuracy of...

Embodiment 2

[0074] This embodiment proposes a control method for an unmanned aerial vehicle with autonomous navigation in the furnace space. The control method for detecting the unmanned aerial vehicle uses the unmanned aerial vehicle with autonomous navigation in the furnace space as described in Embodiment 1. A method for controlling an unmanned aerial vehicle autonomously navigating in a furnace space specifically includes the following steps:

[0075] S101. Detect the status of the drone autonomously navigating in the furnace space;

[0076] S102, judging whether the state of the unmanned aerial vehicle autonomously navigating in the furnace space is in flight operation, if so, then enter S103; if not, then enter S113;

[0077] S103. Control the telescopic component 8 to retract;

[0078] In step 103, when the unmanned aerial vehicle autonomously navigating in the furnace space is performing flight operations, the telescopic assembly 8 is controlled to retract, so as to avoid the shi...

Abstract

The invention provides an in-furnace space autonomous navigation unmanned aerial vehicle which comprises a fuselage main body arranged in the middle and propeller devices arranged at four corners. A laser radar positioning device is arranged on the fuselage main body, a protection structure is arranged on the propeller devices, and the laser radar positioning device is arranged above the fuselage main body. Compared with the prior art, the in-furnace space autonomous navigation unmanned aerial vehicle has the advantages that the laser radar positioning device is arranged on the fuselage main body so that the unmanned aerial vehicle in the furnace space can realize autonomous navigation and autonomous positioning flight; the laser radar positioning device is arranged above the fuselage main body, the effect of a laser radar can be played to the maximum extent, the influence of other devices on the laser shielding angle is reduced, and therefore large data range information is collected, and the positioning precision of the unmanned aerial vehicle is improved; and the protection structure is arranged on the propeller device so that the unmanned aerial vehicle can be effectively prevented from colliding with obstacles in the inspection process.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle capable of autonomous navigation in a furnace space. Background technique [0002] So far, the inspection plan in the confined space inside the boiler of the power plant is to manually control the drone for inspection. The space in the furnace is a closed space. The main feature of the closed space is that it does not have satellite positioning signals. In the case of a signal, the UAV cannot perform positioning and autonomous flight. During the process, the flight position of the aircraft needs to be controlled by the pilot in real time and the real-time absolute position information of the aircraft cannot be known. The inaccurate flight position requires high requirements for the operator, and the operation effect is poor. In addition, the aircraft Without a protective structure, there is a high probability of collision with obstacles during th...
