Description

Technical Field

[0001] This utility model relates to the field of highway inspection drone technology, and in particular to a drone device for highway inspection. Background Technology

[0002] Highway inspection drones are a solution that utilizes drone technology for highway inspection and monitoring. They can replace traditional manual inspections, offering higher efficiency and safety. Typically equipped with various sensors and cameras, they can acquire real-time information about the highway, enabling comprehensive inspection and monitoring, including checking road conditions, traffic flow, the integrity of signs and markings, and the safety of tunnels and bridges.

[0003] For example, a drone device for highway inspection, with publication number CN221138626U, involves inserting an installation pipe into a fixing rod for installation and fixation. Simultaneously, an installation sleeve at one end of a water supply hose is inserted into an installation groove for installation and fixation. The drone is then controlled to take off and bring its cleaning wheel close to the surface of electromechanical equipment on the highway. A servo motor drives a drive rod to rotate, which in turn drives the rotating pipe and cleaning wheel to rotate via a first and second gear. Simultaneously, a water pump draws water from the tank and discharges it through the water supply hose into the rotating pipe, then into the cavity of the cleaning wheel. Finally, the water is sprayed onto the surface of the electromechanical equipment through the cleaning holes, completing the initial rinsing. The cleaning wheel then drives the cleaning column to rotate and further clean the surface of the equipment, resulting in a more thorough and effective cleaning.

[0004] However, during the initial rinsing, the water sprayed onto the equipment surface wets the dust, which can cause scratches to remain on the surface due to friction when the cleaning column rotates, thus affecting the cleaning effect. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a drone equipment for highway inspection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drone for highway inspection includes a drone body and a cleaning wheel. A ventilation arm is installed on the bottom edge of the drone body, offset from the propeller. The ventilation arm is hollow inside, and a U-shaped plate is fixedly installed on the side away from the drone body. The cleaning wheel is rotatably mounted inside the U-shaped plate, and a bevel gear is also installed inside the U-shaped plate. The center line of the bevel gear is parallel to the center line of the cleaning wheel, and both ends of the bevel gear extend outward to be rotatably connected to the inner wall of the U-shaped plate. A transmission gear is installed on one end of the bevel gear on the same side of the cleaning wheel, and the two transmission gears mesh with each other. Ventilation ducts are provided on the left and right sides of the ventilation arm between the fan and the U-shaped plate. One end of the ventilation duct extends into the U-shaped plate and is located on both sides of the cleaning wheel.

[0008] Preferably, an air duct is rotatably connected through the bottom surface of the ventilation arm away from the U-shaped plate, and an air guide shroud for moving to directly below one of the propellers is fixedly connected to the bottom end of the air duct.

[0009] Preferably, a spur gear ring is fixedly installed on the outer surface of the air duct, and a spur gear driven by a motor and meshing with the spur gear ring is rotatably connected to the bottom surface of the ventilation arm.

[0010] Preferably, sliders are slidably inserted into both the upper and lower surfaces of the U-shaped plate, and electric push rods are fixedly installed on the sliders. The extension and retraction directions of the electric push rods are perpendicular to the sliding direction of the sliders, and electric telescopic rods are fixedly installed at the extension and retraction ends of the electric push rods. The extension and retraction ends of the electric telescopic rods extend and retract toward the U-shaped plate, and clamping plates for clamping the surface of the equipment are fixedly connected to the extension and retraction ends.

[0011] Preferably, both the upper and lower surfaces of the U-shaped plate are provided with pneumatic telescopic rods for pushing the slider to slide.

[0012] Preferably, a fan is provided inside the ventilation arm, and the fan blade shaft passes through the ventilation arm near the U-shaped plate and is fixedly connected to a bevel gear block that meshes with the bevel gear component.

[0013] Preferably, the air outlets of the two ventilation ducts are respectively arranged facing the two sides of the surface of the cleaning wheel.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the cleaning wheel is used to clean the surface of the equipment. The airflow from the fan blows on both sides of the cleaning wheel through two ventilation channels, which can directly blow away the dust generated during the cleaning process and the cleaning wheel. This ensures the cleaning effect while also enabling the surface of the cleaning wheel to self-clean, thus facilitating the cleaning effect.

[0016] 2. In this utility model, the airflow in the ventilation arm passes through the fan and drives the fan blades and fan blade shaft to rotate, thereby realizing the rotation of the bevel gear block. Under the action of meshing connection, the bevel gear drives the transmission gear set on its end face to rotate. Similarly, under the action of meshing connection, another transmission gear drives the cleaning wheel to rotate. Thus, the airflow can be used to realize the rotation of the cleaning wheel, reducing power consumption. Attached Figure Description

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figure 1-5 As shown:

[0026] A highway inspection drone device includes a drone body 1 and a cleaning wheel 8. A ventilation arm 4 is installed on the bottom edge of the drone body 1, offset from the propeller. The ventilation arm 4 is hollow inside, and a U-shaped plate 7 is fixedly installed on the side away from the drone body 1. The cleaning wheel 8 is rotatably mounted inside the U-shaped plate 7, and a bevel gear 14 is also installed inside the U-shaped plate 7. The centerline of the bevel gear 14 is parallel to the centerline of the cleaning wheel 8, and both ends of the bevel gear 14 extend outwards to rotatably connect with the inner wall of the U-shaped plate 7. A transmission gear 15 is installed on one end of the bevel gear 14 on the same side as the cleaning wheel 8. The drive gear 15 is engaged with the ventilation arm 4, and a fan 17 is installed inside the ventilation arm 4. The fan blade shaft of the fan 17 passes through the ventilation arm 4 near the U-shaped plate 7 and is fixedly connected to a bevel gear block 16 that is engaged with the bevel gear component 14. In actual use, the airflow in the ventilation arm 4 passes through the fan 17 and drives the fan blades and fan blade shaft of the fan 17 to rotate, thereby rotating the bevel gear block 16. Under the action of the engagement, the bevel gear component 14 drives the transmission gear 15 installed on its end face to rotate. Similarly, under the action of the engagement, another transmission gear 15 drives the cleaning wheel 8 to rotate, so that the cleaning wheel 8 can be used to clean the surface of the equipment.

[0027] Furthermore: A draft pipe 3 is rotatably connected to the bottom surface of the ventilation arm 4 away from the U-shaped plate 7. A guide shroud 2 for moving to directly below one of the propellers is fixedly connected to the bottom end of the draft pipe 3. A spur gear ring 6 is fixedly installed on the outer surface of the draft pipe 3. A spur gear 5 driven by a motor and meshing with the spur gear ring 6 is rotatably connected to the bottom surface of the ventilation arm 4. By installing a motor on the ventilation arm 4 to drive the spur gear 5 to rotate, the meshing spur gear ring 6 can drive the draft pipe 3 and the guide shroud 2 to rotate. When the drone body 1 is fixed to the surface of the equipment, the drone body 1 will not rise or fall when the propeller on the drone body 1 rotates, but the generated air can enter the ventilation arm 4 along the guide shroud 2 and the draft pipe 3.

[0028] Furthermore: Slider 13s are slidably inserted into both the upper and lower surfaces of the U-shaped plate 7. An electric push rod 10 is fixedly mounted on the slider 13. The extension and retraction directions of the electric push rod 10 are perpendicular to the sliding direction of the slider 13, and an electric telescopic rod 9 is fixedly mounted at the extension end of the electric push rod 10. The extension and retraction ends of the electric telescopic rod 9 extend towards the U-shaped plate 7, and a clamping plate 11 for holding the surface of the equipment is fixedly connected to the extension end. Pneumatic telescopic rods 12 for pushing the slider 13 to slide are provided on both the upper and lower surfaces of the U-shaped plate 7. In actual operation, after the drone body 1 moves to the equipment, the extension of the electric telescopic rod 9 allows the two clamping plates 11 to clamp the top and bottom surfaces of the equipment respectively. The U-shaped plate 7, ventilation arm 4, and drone body 1 can be fixed in position, ensuring that the drone body 1 will not shake when the airflow generated by one of the propellers of the drone body 1 enters the air guide shroud 2. With the clamping plate 11 holding the equipment, the relative position of the equipment to the U-shaped plate 7 can be adjusted by extending and retracting the electric push rod 10, which can adjust the pressure of the rotating cleaning wheel 8 in contact with the equipment surface. The extension and retraction of the pneumatic telescopic rod 12 can make the slider 13 drive the clamping plate 11 to move relative to the U-shaped plate 7, so that the cleaning wheel 8 installed in the U-shaped plate 7 can slide left and right on the equipment surface, ensuring complete cleaning of the equipment surface.

[0029] Furthermore, ventilation ducts 18 are provided on both sides of the ventilation arm 4 between the fan 17 and the U-shaped plate 7. One end of the ventilation duct 18 extends into the U-shaped plate 7 and is located on both sides of the cleaning wheel 8. The air outlets of the two ventilation ducts 18 are respectively set towards the two sides of the surface of the cleaning wheel 8. The airflow from the fan 17 blows onto both sides of the cleaning wheel 8 through the two ventilation ducts 18, so that the dust generated during the cleaning process of the cleaning wheel 8 can be directly blown away from the equipment and the cleaning wheel 8, ensuring the cleaning effect while achieving self-cleaning of the surface of the cleaning wheel 8.

[0030] Working principle: The drone body 1 is controlled to move to the equipment. The top and bottom surfaces of the equipment are clamped by two clamping plates 11. The distance between the equipment and the cleaning wheel 8 is adjusted by the extension and retraction of the electric push rod 10. Then, the motor drives the spur gear 5 to rotate, which causes the spur gear ring 6 to drive the air duct 3 and the air guide shroud 2 to rotate until the air guide shroud 2 moves directly under one of the propellers to receive the airflow generated by the propeller. The generated airflow enters the ventilation arm 4 along the air guide shroud 2 and the air duct 3. The airflow in the ventilation arm 4 passes through the fan 17 and drives the fan blades and fan shaft of the fan 17 to rotate, which causes the bevel gear block 16 to rotate. This causes the bevel gear 14 to drive the transmission gear 15 set on its end face to rotate. Similarly, under the meshing connection, the other transmission gear 15 drives the cleaning wheel 8 to rotate. The cleaning wheel 8 can then be used to clean the surface of the equipment. The airflow from the fan 17 blows through the two ventilation channels 18 to both sides of the cleaning wheel 8, which can directly blow away the dust generated during the cleaning process of the cleaning wheel 8 from the equipment and the cleaning wheel 8, ensuring the cleaning effect while achieving self-cleaning of the surface of the cleaning wheel 8.

[0031] The wiring diagrams of the UAV body 1, electric telescopic rod 9, electric push rod 10, and pneumatic telescopic rod 12 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the UAV body 1, electric telescopic rod 9, electric push rod 10, and pneumatic telescopic rod 12 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
