Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles, and in particular relates to an unmanned aerial vehicle for inspection. Background Art

[0002] In cold seasons, people use natural gas for heating. In order to ensure the safety of the pipelines, staff are required to inspect the pipelines from time to time. Due to the harsh outdoor environment, staff use drones to inspect the pipelines.

[0003] When existing inspection drones are used in cold seasons, some rain or snow will stick to the lens during flight and landing, requiring staff to clean it manually, which increases the staff's workload. In addition, the staff cannot clean the lens with dirt during flight in time, which can easily interfere with the drone's monitoring of the pipeline. Utility Model Content

[0004] The utility model provides a patrol inspection drone, aiming to solve the problem that when the drone lens is stained with rain or snowflakes, it cannot be automatically cleaned.

[0005] To solve the above problems, the utility model is implemented as follows: a patrol drone, comprising: a drone body and a camera device arranged at the bottom of the drone body; a mounting plate arranged below the drone body; a rotating rod rotatably mounted on the mounting plate; a brush fixedly mounted on one side of the rotating rod for cleaning the camera device lens; a sliding mechanism arranged on the drone body for driving the brush to slide; and a rotating mechanism arranged on the sliding mechanism and the mounting plate for driving the brush to rotate.

[0006] Preferably, the sliding mechanism includes: a group of mounting blocks fixedly mounted on the bottom of the drone body; a one-way screw rotatably mounted on the group of mounting blocks; a slider threadedly sleeved on the one-way screw; and a motor fixedly mounted on the bottom of the drone body, the output shaft of the motor being fixedly connected to the one-way screw.

[0012] Compared with the related art, the inspection drone provided by the utility model has the following beneficial effects:

[0013] 1. The brush is driven to rotate by the rotating mechanism, so that the brush can clean the stains or rainwater on the camera lens, which is convenient for the operation of the drone body. The brush is driven to slide away from the camera by the sliding mechanism, so as to ensure that the brush does not block the lens, which is conducive to the camera equipment to inspect the pipeline. The detachable connecting block is set to facilitate the removal of the brush from the drone body, which is convenient for cleaning or replacement of the brush.

[0014] 2. The gear is driven to rotate by the rack, so that the brush can swing back and forth within a fixed range, ensuring that the brush will not hit the drone body when rotating, which is beneficial to the protection of the drone body. The rack is guided by the guide block to ensure that the rack slides smoothly, which is beneficial to the rack driving the gear to rotate;

[0015] 3. By using the isolation pad in combination with the shock-absorbing spring, the vibration can be effectively isolated, so as to facilitate the shock absorption operation of the vibration generated when the drone body lands. The shock-absorbing legs can be used to prevent the drone body from tipping over, so that the drone body can be auxiliary supported when it lands to ensure that it will not tip over, and the protection effect is better.

[0016] Compared with the prior art, the inspection drone provided by this solution has the advantage of being able to automatically clean the camera lens, thereby ensuring that rain or stains will not affect the lens. BRIEF DESCRIPTION OF THE DRAWINGS
