Description

Technical Field

[0001] The utility model relates to the technical field of bridge detection, in particular to a bridge detection unmanned aerial vehicle with a protection structure. Background Technique

[0002] Traditional bridge inspections usually require inspectors to climb the bridge in person and use tools such as ropes and ladders for high-altitude operations, which pose significant safety risks. Drone detection can avoid direct exposure of personnel to dangerous environments and significantly reduce the probability of safety accidents. Moreover, drones can quickly fly over bridges for all-round shooting and inspection, greatly shortening the inspection time and improving work efficiency.

[0003] The high-definition cameras and sensors carried by drones can capture tiny cracks, corrosion, and other damage conditions on bridges, and can even perform thermal imaging detection to discover potential problems inside the bridges. This high-precision detection ability helps to timely detect diseases and hidden dangers of bridges, so drones are widely used in bridge detection work.

[0004] However, when using drones for bridge detection, it is necessary to minimize the distance between the drone and the bridge as much as possible to improve the detection accuracy. However, it is difficult to precisely control the position of the drone when manually controlling its flight, resulting in the drone being easily damaged by colliding with the bridge. Therefore, a protection structure needs to be set on the drone to protect the drone and the detection device.

[0005] For example, the Chinese utility model patent with the patent number 201720161541.1 provides a multi-rotor drone. The drone is provided with a protective cover around the rotor, which can ensure that the rotor is isolated from foreign objects during flight, effectively reducing external threats and improving the service quality of the drone. However, most of the existing detection drones only protect the wings, which is not convenient for comprehensively protecting the drone, the wings, and the detection device above them during the bridge detection process, resulting in the top of the drone being still easily damaged by impact during the top-attachment detection, reducing the service life of the drone. Summary of the Utility Model

The multiple groups of protective rods cooperate with the support components to form a framework for accommodating the drone body.

[0012] In a preferred embodiment, a bearing is arranged on the drone body, and the rotating shaft is rotatably arranged in the bearing along its axis.

[0013] In a preferred embodiment, the support component includes a connecting seat, the connecting seat is sleeved on the end of the rotating shaft, multiple groups of support frames are arranged circumferentially on the support component, and the end of the protective rod is connected to the support frame.

[0014] In a preferred embodiment, the connecting seat is installed on the end of the rotating shaft through a first fixing pin, and the protective rod and the support frame are connected through a second fixing pin.

[0015] In a preferred embodiment, a passive wheel is rotatably sleeved on the end of the protective rod, and the second fixing pin penetrates through the passive wheel and the support frame to be connected to the protective rod.

[0016] In a preferred embodiment, limiters are arranged at both ends of the rotating shaft, and the limiters are abutted against the connecting seat.

[0017] In a preferred embodiment, the ends of every two adjacent groups of support frames are connected through a protective frame.

[0018] In a preferred embodiment, the protective rod is of a hollow structure.

Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0032] Embodiment:

[0033] As Figure 1 、 2 shown, the present utility model provides a bridge inspection drone with a protection structure, which includes a drone main body 101. A bearing 102 is arranged on the drone main body 101, and a rotating shaft 103 that can rotate along its axis is arranged in the bearing 102. Both ends of the rotating shaft 103 extend outside the drone main body 101. Two sets of support components are also included, and the two sets of support components are respectively arranged at both ends of the rotating shaft 103.

[0034] When the inspection drone is in use, the inspection device can be carried by the drone main body 101 to inspect the bridge. Compared with the traditional manual inspection, the inspection drone can improve the inspection efficiency and the safety during the inspection process. The rotating shaft 103 can rotate in the bearing 102, so that the support components can rotate along the axis of the rotating shaft 103.

[0035] As Figure 1 、 3 shown, in this embodiment, a plurality of protection rods 301 are also included. The plurality of protection rods 301 are arranged at intervals in the circumferential direction of the drone main body 101, and both ends thereof are respectively connected to the two sets of support components. The plurality of protection rods 301 and the support components cooperate to form a frame for accommodating the drone main body 101. The support component includes a connecting seat 201, the connecting seat 201 is sleeved on the end of the rotating shaft 103, and a plurality of support frames 202 are arranged in the circumferential direction on the support component. The end of the protection rod 301 is connected to the support frame 202.

[0036] During the process of inspecting the bridge by the drone main body 101, the plurality of protection rods 301 and the support frames 202 can cooperate to provide all-round protection for the drone main body 101, the wings and the inspection device above it, and will not affect the normal flight of the drone main body 101. Even when performing a top-contact inspection on the bridge, the protection rods 301 can also protect the top of the drone main body 101, thereby preventing the top of the drone main body 101 from being impacted.

[0037] As Figure 4 、 5As shown in the figure, in this embodiment, the connecting seat 201 is installed at the end of the rotating shaft 103 through the first fixing pin 105, and the protective rod 301 and the support frame 202 are connected through the second fixing pin 303. The connecting seat 201 and the protective rod 301 are installed through the first fixing pin 105 and the second fixing pin 303. Among them, the ends of the first fixing pin 105 and the second fixing pin 303 can be fixed in the form of a buckle, or can be fixed in the form of interference fit or threaded connection. The connecting seat 201 and the protective rod 301 can be disassembled by disassembling the first fixing pin 105 and the second fixing pin 303, which is convenient for the separate use and storage of the UAV body 101.

[0038] As Figure 5 shown in the figure, in this embodiment, a driven wheel 302 is rotatably sleeved at the end of the protective rod 301, and the second fixing pin 303 passes through the driven wheel 302 and the support frame 202 to be connected to the protective rod 301. Through the setting of the driven wheel 302, when the UAV body 101 is attached to the wall or the ceiling, it can ensure that the driven wheel 302 is in full contact with the bridge, so that the overall mechanism can move straight forward or up and down, realizing the close detection and fixed shooting of the bridge structure surface to improve the detection effect.

[0039] As Figure 3 、 4 shown in the figure, in this embodiment, limiters 104 are provided at both ends of the rotating shaft 103, and the limiters 104 are in contact with the connecting seat 201. Through the setting of the limiters 104, the connecting seat 201 is prevented from sliding on the rotating shaft 103, improving the stability of the structure of the detection UAV. The ends of every two adjacent groups of support frames 202 are connected through a protective frame 203. Through the setting of the protective frame 203, the structure of the support frame 202 is strengthened, and at the same time, the protection effect is improved, preventing external objects from entering the frame through the two support frames 202 and causing damage to the UAV body 101. And the protective rod 301 is a hollow structure to reduce the load of the UAV body 101 and improve the endurance of the UAV body 101. The protective rod 301 can also be made of a carbon fiber hollow rod to reduce the weight as much as possible while ensuring its protection effect.

[0040] The specific usage method and beneficial effects of the present utility model:

[0041] The detection UAV can carry a detection device on the UAV main body 101 to detect places that are inaccessible to humans in the bridge. During the detection process, a support component can support multiple groups of protective rods 301, and the multiple groups of protective rods 301 cooperate with the support component to form a framework for accommodating the UAV main body 101, so as to provide all-round protection for the UAV main body 101, the wings and the detection device above them. Even when the UAV main body 101 conducts ceiling detection, it can effectively prevent the UAV main body 101 and the detection device from being damaged by impact, improving the protection effect on the UAV main body 101, the wings and the detection device during detection.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments. Based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art.
