The moving part uses the inner driving part to drive the outer cleaning part, so that it can clean the outside of the transparent sealing plate at the window to prevent dust and debris attached thereto from affecting the shooting effect of the photogrammetry equipment. The interior of the lower trapezoidal protective cover is connected to the mounting plate through a connecting shaft. A ring body is fixed on the connecting shaft. Ring body opening grooves are opened on the left and right sides of the ring body. A shaft body is fixed in the ring body opening groove. The shaft body is rotatably connected to a rotating plate. A camera is fixed on the outer end surface of the rotating plate. The two cameras on the left and right sides respectively realize the functions of shooting and measuring. The camera is connected to the top electrical box through an internal cable connected to the rotating plate. A mounting block is set on the back of the camera. Under the action of its own gravity and without other intervention, it can drive the rotating plate to be in a vertical state. In order to be able to shoot normally, a tightening structure is installed on the mounting plate. The output end of the tightening structure is connected to the inner end of the rotating plate. Under the pulling of the tightening structure, the other end of the rotating plate can be pulled down, so that the outer end where the camera is installed is lifted upward. This process is also the adjustment of the angle of the camera direction.

[0005] As a preferred technical solution of the utility model, the transparent sealing plate at the window is an acrylic plate, and a transparent explosion-proof glass plate can also be used.

[0006] As a preferred technical solution of the utility model, the outer cleaning part includes an outer stabilizing shaft and a cleaning plate. The windows are located on the outer side of the transparent sealing plate, and the upper and lower ends are fixed with the outer stabilizing shaft. The upper and lower ends of the cleaning plate are movably mounted on the outer stabilizing shaft, and one side thereof is in contact with the outer surface of the transparent sealing plate. The cleaning plate is made of magnetic material, and a sponge brush is integrally formed on the periphery of the contact surface with the transparent sealing plate. Under the action of the inner drive, the cleaning plate can be moved along the outer surface of the transparent sealing plate, and the debris attached to its surface can be cleaned during the movement to ensure a good shooting and measurement effect.

[0007] As an optimal technical solution of the utility model, the inner driving part includes an inner stabilizing shaft, a magnetic plate, a connecting frame, a middle mounting plate and a lead screw. The window is located at the upper and lower ends of the inner side of the transparent sealing plate, and the inner stabilizing shaft is fixed thereto. The upper and lower ends of the magnetic plate are mounted on the inner stabilizing shaft. The left and right magnetic plates are connected by a connecting frame. The middle part of the connecting frame is a middle mounting plate, which is installed in conjunction with a lead screw rotatably installed in the middle of the lower trapezoidal protective cover. A motor is installed in the middle of the rear side of the lower trapezoidal protective cover. The motor is electrically connected to the top electrical box through a cable, and drives the lead screw. The rotation of the lead screw drives the connecting frame to move, so that the magnetic plate moves along the inner stabilizing shaft. Due to the magnetic attraction between the magnetic plate and the cleaning plate, the cleaning plate can be driven to move with it during its movement to complete the cleaning of the outside of the transparent sealing plate.

[0008] As a preferred technical solution of the utility model, the tightening structure includes a winding motor and a rope. The connecting shaft and the mounting plate are hollow inside. The wiring of the winding motor fixed on the mounting plate is finally connected to the top electrical box through the hollow of the connecting shaft and the mounting plate.

The contact surface between the shaft body fixed in the opening groove of the ring body and the rotating plate rotatably connected thereto has a resistance layer composed of friction material. The purpose of setting the resistance layer is that the rotating plate can only rotate under the action of the camera and the counterweight block on its back or when the winding motor is started, so as to avoid shaking due to vibration during the flight of the drone.

[0009] The beneficial effects of the utility model are as follows: the operation of the inner driving part can drive the outer cleaning part to clean the outer side of the transparent cover plate of the window, remove debris and attachments, so as to ensure that the camera can achieve good shooting and measurement effects; the angle of the camera can be adjusted through the ring opening groove, rotating plate, winding motor and rope; during use, the remote control of the winding machine through the Internet of Things remote intelligent controller can achieve real-time adjustment, which is more flexible in actual use.

[0016] As a preferred technical solution of the utility model, the transparent sealing plate at the window 6 can be an acrylic plate or a transparent tempered glass.

[0017] As a preferred technical solution of the utility model, in order to keep the transparent cover plate at the window clean and tidy to ensure a good shooting and measuring effect, an outer cleaning part is provided on the outer side of the window 6 located on the transparent cover plate, specifically including an outer stabilizing shaft 7 and a cleaning plate 8. The outer stabilizing shaft 7 is fixed at the upper and lower ends of the window 6 located on the outer side of the transparent cover plate. The upper and lower ends of the cleaning plate 8 are movably mounted on the outer stabilizing shaft 7, and one side thereof is in contact with the outer surface of the transparent cover plate. The cleaning plate 8 is made of a magnetic material, and a sponge brush is integrally formed on the periphery of the contact surface with the transparent cover plate.
