Technical Field

[0001] The utility model relates to an anti-collision spherical unmanned aerial vehicle, belonging to the technical field of bridge detection. Background Art

[0002] Bridge inspection is a technical investigation of the use of bridges. If a bridge has defects and damaged parts, and there is a serious situation and a trend of development, it is necessary to understand the main causes of the defects and damage as soon as possible, so as to analyze and evaluate their impact on the quality and bearing capacity of the bridge, and provide a reference data basis for reinforcement design and bridge maintenance. Therefore, bridge inspection is the premise of bridge maintenance, repair and reinforcement, the guarantee for determining whether the maintenance and reinforcement plan is reliable, and an indispensable and important part of bridge assessment, maintenance, repair and reinforcement.

[0003] After a long period of use, a bridge will develop a series of superficial defects, such as honeycombs and pockmarks. The traditional method mainly relies on manual visual inspection or the use of cameras and crack width gauges for inspection, which consumes a lot of manpower and material resources. When using drones for inspection and shooting, the existing drone devices have certain defects when used. During the flight, the drone's structure is unstable due to external factors such as weather and wind speed, resulting in collisions, damage to the body or rotor, and failure to work normally. Secondly, the shooting at the bottom of the bridge or in some poor visibility conditions is not clear, which also affects the accuracy of the test results. Utility Model Content

[0004] The utility model aims to solve the problem that the UAV may be unstable due to the influence of external factors such as weather and wind speed during flight, thereby causing collisions, damaging the body or rotor, and causing failure to work normally. An anti-collision spherical UAV for bridge inspection is proposed.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problems is: the utility model includes a drone body, two connecting rods, a balance ring, a spherical outer frame, a camera and a camera fixing frame; the drone body is arranged in the balance ring, the two connecting rods are symmetrically arranged on both sides of the drone body, the inner ends of the connecting rods are fixedly connected to the drone body, the outer ends of the connecting rods are rotatably connected to the inner surface of the balance ring, the balance ring is arranged in the spherical outer frame, the outer surface of the balance ring is rotatably connected to the spherical outer frame, and the camera is installed on the upper surface of the drone body through the camera fixing frame.

[0006] Furthermore, the outer end of the connecting rod is rotatably connected to the inner surface of the balancing ring through a ball bearing rotating joint, and the outer surface of the balancing ring is rotatably connected to the spherical outer frame through a ball bearing rotating joint.

[0007] Furthermore, a fill light is provided on the camera fixing bracket, and the fill light is oriented in the same direction as the camera.

[0008] Furthermore, the spherical outer frame is a soccer-ene molecular structure composed of a plurality of carbon fiber rods and a plurality of carbon rod connectors.

[0009] Furthermore, a signal receiver, a controller and a storage are provided in the drone body. The signal receiver is used to receive a control signal and transmit the control signal to the controller. The controller controls the drone body according to the control signal received by the signal receiver. The storage is used to store image information collected by the camera.

[0010] The beneficial effects of the utility model are: 1. When a collision occurs, the spherical outer frame can reduce the impact on the balance ring and the internal structure, making the drone body more stable when working;

[0011] 2. At the bottom of the bridge or in poor light conditions, the boost light can improve the shooting effect and increase the accuracy of the detection results;

[0012] 3. The utility model has a simple structure, is easy to install and operate, has strong anti-collision performance, and has more stable performance during high-altitude operations. BRIEF DESCRIPTION OF THE DRAWINGS
