At the middle of the bottom end of the UAV body, landing gears are symmetrically arranged. A fixed seat is arranged between the top ends of the landing gears. A fixed frame is connected below the fixed seat. A first fixing plate is arranged at the top of the fixed frame. A second fixing plate is arranged at the bottom of the fixed frame. An installation groove is opened at the center of the second fixing plate. An installation frame is fixed above the installation groove. A camera is obliquely arranged on one side of the installation frame. A tempered glass lens is connected between the first fixing plate and the second fixing plate. A shielding plate is obliquely arranged at the top of the tempered glass lens. An arc-shaped protrusion is arranged at the middle of one side of the shielding plate.
[0004] During the use of the existing road information sampling device for traffic accident survey, the high-definition camera carried is used to take detailed images of the accident scene. Due to long-term operation, the surface of the high-definition camera is easily contaminated with dust and the device cannot automatically clean the surface of the high-definition camera, resulting in dust particles adhering to the surface of the camera lens, forming a film, blocking part of the light from entering the lens, and causing the captured images to become blurred.

Specific embodiments
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] As Figures 1 to 4 shown, the present utility model provides a road information sampling device for traffic accident survey, including an unmanned aerial vehicle 1. A first support 2 is installed on one side of the unmanned aerial vehicle 1, a first camera 3 is installed on the first support 2, a second support 4 is installed at the bottom of the unmanned aerial vehicle 1, a second camera 5 is installed on the second support 4, and the second camera 5 is arranged to incline downward. A nozzle 6 is arranged on one side of the second camera 5. A storage tank 7 is fixedly installed on one side of the bottom of the unmanned aerial vehicle 1. The storage tank 7 contains cleaning liquid. A liquid injection pipe is installed on the storage tank 7. A diversion mechanism is installed on the storage tank 7. The diversion mechanism is communicated with the nozzle 6. The diversion mechanism can introduce the cleaning liquid in the storage tank 7 to the nozzle 6. The diversion mechanism includes a suction pump 8. The suction pump 8 is fixedly installed on the storage tank 7. The inlet pipe of the suction pump 8 is communicated with the inner cavity of the storage tank 7. The discharge end of the suction pump 8 is communicated with and fixedly installed with a conduit 9. A slidable movable tube 10 is inserted into the conduit 9. The other end of the movable tube 10 is fixedly connected to the nozzle 6 and the two are in a communicated state. A balancing device is installed on the unmanned aerial vehicle 1.
[0022] Among them, as Figure 3 and Figure 4As shown in the figure, the diversion mechanism further includes a moving component, which is installed at the bottom of the drone 1 and connected to the movable pipe 10. The moving component can drive the nozzle 6 to move horizontally. The moving component includes a bracket 11, which is fixedly connected to the bottom of the drone 1. A rotating shaft 12 is rotatably installed at the lower end of the bracket 11. A driving wheel 13 is fixedly installed on the rotating shaft 12. A rack 14 is fixedly installed on the movable pipe 10. The rack 14 meshes with the driving wheel 13. A motor 15 is fixedly installed at the bottom of the drone 1. A synchronous belt mechanism 16 is installed between the output shaft of the motor 15 and the rotating shaft 12. A sealing rubber ring is arranged inside the conduit 9. A voice recording device is installed on the drone 1.
[0023] The working principle and usage process of the present utility model are as follows:
[0024] The first camera 3 and the second camera 5 carried by the drone 1 work synchronously and coordinately. The first camera 3 captures the image information in front of the drone 1 to assist the flight of the drone 1. The second camera 5 captures the road information and traffic information below the drone 1. During normal operation, the nozzle 6 is far away from the second camera 5, and the nozzle 6 will not block the normal shooting work of the second camera 5. When it is necessary to clean the second camera 5, the motor 15 drives the driving wheel 13 to rotate. The driving wheel 13 drives the rack 14 to move. The rack 14 and the movable pipe 10 move synchronously. The movable pipe 10 and the nozzle 6 move synchronously. The nozzle 6 moves to the position of the second camera 5. Then, the cleaning liquid in the storage tank 7 is introduced into the conduit 9 through the suction pump 8, and then introduced into the nozzle 6 through the movable pipe 10. Thus, the nozzle 6 sprays the cleaning liquid onto the surface of the second camera 5 to clean the dust on the surface of the second camera 5. The automatic cleaning function can remove the dust on the camera surface regularly or as needed, ensuring that the camera always remains clean, so as to capture clearer and more accurate image data. The clear image data helps to more accurately extract road information, such as vehicle traces, road markings, etc., providing a reliable basis for accident analysis and liability determination.
