Description

Technical Field

[0001] The utility model relates to the technical field of highway inspection devices, in particular to a highway inspection unmanned aerial vehicle. Background Art

[0002] With the expansion of highways, the difficulty of inspection is increasing. If we rely solely on manual inspection, the workload will be heavy. Therefore, drone inspection is gradually replacing manual inspection.

[0003] Drone inspection is to use a drone equipped with a camera, in conjunction with a corresponding wireless data transmission device, to record highway images through the camera to achieve the purpose of inspection. However, when existing highway inspection drones are in use, the camera is generally fixed on the drone body in an exposed state, and the camera lacks corresponding protective components. This causes the camera to be easily damaged if the drone falls over due to unstable landing. In addition, the landing frames of existing highway inspection drones are generally fixed brackets, lacking corresponding buffer devices, which makes it more likely to cause accidents during landing, thereby damaging the camera. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a highway inspection drone, and the technical solution to the problem is that it includes a drone body, characterized in that four buffer legs arranged in a rectangular array are installed at the lower end of the drone body, a protective cover is fixedly connected to the lower end of the drone body, a guide support sleeve is fixedly connected to the lower end of the drone body, a mounting rod is slidably connected to the mounting rod, a mounting seat is fixedly connected to the mounting seat, a camera located in the protective cover is fixedly connected to the mounting seat, and a driving device for driving the mounting rod is arranged at the lower end of the drone body;

[0005] The driving device includes two support plates corresponding to each other in the front and back and fixedly connected to the drone body, two sliding rods arranged corresponding to each other in the left and right are fixedly connected to the opposite ends of the two support plates, and a lead screw is rotatably connected to the opposite ends of the two support plates. The lead screw is threadedly connected to a driving rod that slidably cooperates with the two sliding rods, a push rod is fixedly connected to the front end of the driving rod, and the push rod is fixedly connected to the mounting rod, and the support plate on the rear side is fixedly connected to a stepping motor for driving the lead screw.

[0006] Preferably, each of the buffer legs includes a sleeve fixedly connected to the drone body, the sleeve is coaxially slidably connected to a buffer rod, the outer wall of the sleeve is provided with two vertical grooves symmetrically arranged about its axis, the outer edge of the buffer rod is fixedly connected to two sliders which correspond to the vertical grooves one by one and vertically slide together, the upper end of the buffer rod is coaxially fixedly connected to the lower end of a spring, the upper end of the spring is fixedly connected to the inner bottom surface of the upper side of the sleeve, and the lower end of the buffer rod is coaxially fixedly connected to a rubber pad.

[0007] The beneficial effects of the utility model are:

[0008] 1. When the present application is in use, the driving device provided can drive the mounting frame to slide along the guide support sleeve, and then drive the camera on the mounting seat to enter and exit the protective cover. When the UAV takes off, the driving device can cooperate with the mounting rod to drive the camera to extend out of the protective cover for recording, thereby completing the inspection operation; when the inspection is completed and before landing, the driving device can also cooperate with the mounting rod to drive the camera back into the protective cover.

[0017] The following is combined with Figure 1-5 The specific implementation methods of the utility model are further described in detail.

[0018] Embodiment 1, the technical solution is that when the present application is in use, the provided driving device 8 can drive the mounting frame to slide along the guide support sleeve 4, and then can drive the camera 7 on the mounting seat 6 to enter and exit the protective cover 3. When the UAV takes off, the driving device 8 can cooperate with the mounting rod 5 to drive the camera 7 to protrude from the protective cover 3 for recording, and then complete the inspection operation; before the inspection is completed and before landing, the driving device 8 can cooperate with the mounting rod 5 to drive the camera 7 back into the protective cover 3. Under the protection of the protective cover 3, the camera 7 can be protected in case of accidents when the UAV body 1 is landed. The provided buffer leg 2 is connected with the buffer rod 16 through the sleeve 15, and the elastic deformation ability of the spring 19 can be used to buffer the landing of the UAV body 1 to ensure a smooth landing. The present application has a simple structure, is easy to use, and has strong practicality.

[0019] Embodiment 2, based on embodiment 1, specifically, when the present application is in use, the stepper motor 14 can be opened and closed and rotated forward and reversely by remote control technology, and its specific control can be carried out by using existing technology, which will not be described in detail in the present application. When conducting highway inspection, the drone body 1 is controlled to fly along the highway. After the drone is launched and before the inspection begins, the stepper motor 14 on the support plate 9 is started to rotate forward to the set stroke. The forward rotation of the stepper motor 14 will drive the lead screw 11 to rotate forward, and the forward rotation of the lead screw 11 will drive the drive rod 12 to move forward along the slide rod 10, and then the push rod 13 will also move forward with the drive rod 12. The forward movement of the push rod 13 will drive the installation rod 5 smoke guide sleeve to move forward, and the forward movement of the installation rod 5 will drive the camera 7 on the mounting seat 6 to extend the protective cover 3 forward, and then the camera 7 can record the inspection operation. The guide sleeve provides stable support for the installation rod 5 and also facilitates the movement of the installation rod 5.

[0020] When the inspection is completed and before the drone body 1 lands, it is necessary to control the camera 7 to reset back to the protective cover 3. Specifically, the control component motor reverses the set stroke to reset, and the stepper motor 14 reverses to drive the lead screw 11 to reverse, and then the lead screw 11 will drive the drive rod 12, the push rod 13, the mounting rod 5 and the camera 7 and other related components to move backward and reset, and then the camera 7 will return backward to the protective cover 3.

[0021] Embodiment 3, on the basis of embodiment 2, a buffer rod 16 is set in the sleeve 15, and the buffer rod 16 is connected to the vertical groove 17 on the sleeve 15 through a slider 18, so that the buffer rod 16 can slide vertically relative to the tube, and with the elastic deformation ability of the spring 19, it can be used for buffering during landing, and the rubber pad 20 at the lower end of the buffer rod 16 also has a certain buffering ability. There are four buffer legs 2, that is, the drone body 1 can have multiple fulcrums when landing to ensure a smooth landing.
