Description

Multi purpose mission type drones

The present invention relates to a drone characterized in that a square frame is mounted on the outer surface of a propeller to perform a visual inspection of a lower part of a bridge, including a real-time monitoring device, and to prevent collision with an obstacle during the inspection.

Drone (Drone) refers to an airplane or a helicopter-shaped vehicle that is flying by induction of radio waves without human beings, and is mainly used for military purposes such as targeting, reconnaissance, and surveillance. It is used for a purpose.

For example, the field of use of drones is gradually widening, such as a helicam that mounts a camera on a drone and remotely controls the drone to shoot an image and is widely used for shipping.

Also, in recent years, with the development of the industry, many large structures have been constructed. In particular, in the case of bridges, the span and scale are very large, so some structures are formed with a span of more than 1 km. In order to ensure safety, industrial infrastructures such as bridges are periodically inspected and diagnosed for safety, and are primarily inspected for cracks and corrosion in structures depending on appearance inspection. Existing inspection method is to install a work platform such as a scaffold or a mobile passage and a scaffold at the bottom of a bridge through which water flows, and on top of that, the worker investigates the corrosion and crack conditions of the bridge. However, if there is a lot of expenses and there is a lot of wind, there is a disadvantage that the safety of workers cannot be secured because the worktable under the bridge is shaken. In the case of a dam, the scale is large, and it is difficult for a person to take a picture in close proximity for stability reasons at a location where water flows. In addition, because the transmission facilities are high in height and high-voltage electricity flows, it is difficult for humans to inspect them closely. For example, in order to shoot insulators, metal fittings, etc. of structures and transmission towers, the inspector should take pictures using high-voltage power lines, structures and transmission towers, and use shooting equipment such as an elevated ladder to take pictures. There is a problem that the danger of safety accidents caused by and the scope of shooting are limited.

Also, it is not easy to safely operate the drone, and the drone is often damaged due to the impact of landing the drone.However, there is little opportunity to receive training on the drone's structure, assembly method, or control method. There is a problem in that an accident cannot be avoided due to failure to familiarize with various types of information or control methods.

Prior art is Korean Patent Registration No. 10-1762536 (drone and control method for obstacle avoidance and landing on slopes). Here, a technique of protecting a drone's propeller with an upper cover and a lower cover to protect it from impact is disclosed. have.

In the case of the prior art, when a drone collides with an obstacle, it absorbs the impact generated during a collision, which can cause a mechanical defect in the drone in the long term, and additional equipment such as imaging equipment and radar sensors other than propellers. There was a problem that could not be protected.
