Specific embodiments

[0025] The following will describe in detail a monitoring component of a field painting UAV provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; and the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present utility model.

[0026] As Figure 1 - Figure 4 shown, an embodiment of the present utility model provides a monitoring component of a field painting UAV, including: a UAV body 1, with two symmetrically distributed landing gears 2 arranged at the bottom, providing stable takeoff and landing support for the UAV; a machine box 3, fixed between the two landing gears 2 at the bottom of the UAV body 1, and the bottommost position of the machine box 3 is higher than the bottom feet of the landing gears 2, which not only ensures the stability of the machine box 3 but also avoids wear and pollution caused by the direct contact of the machine box 3 with the ground during takeoff and landing; a spraying assembly 4, arranged at the inner edge position of the machine box 3 for spraying painting pigments; a camera 8, fixed at the center position inside the machine box 3, and the camera lens of the camera 8 passes through the bottom wall of the machine box 3 and protrudes outside the machine box 3; a protective cover 9, in a circular shell structure, rotatably connected with the machine box 3, and is set to isolate the camera area of the spraying assembly 4 when the spraying assembly 4 sprays pigments. The protective cover 9 can quickly cover the lens area of the camera 8 during spraying operations, preventing pigments from splashing onto the lens and affecting the shooting quality. This instant protection function ensures that the camera 8 can maintain a clear field of view before each painting, without the need to frequently clean the lens, improving the operation efficiency and continuity.

[0027] Among them, the spraying assembly 4 includes a feed pipe connected to the material supply pipe, and a main pipe located inside the machine box 3 and communicating with the feed pipe. The main pipe is connected with nozzles through branch pipes. There are multiple nozzles, which are symmetrically distributed on opposite sides of the machine box 3, and the output direction is downward. The pigment is transported by an external gear pump in cooperation with a metering device. The pigment enters the main pipe through the feed pipe, is then transported through the branch pipes, and finally sprayed through the nozzles.

[0028] As Figure 3 shown, a through hole 5 is opened at the center of the bottom wall of the machine box 3 for the camera of the camera 8 to extend outside the machine box 3. Among them, the camera 8 uses a 4K high-resolution camera and can be adjusted at multiple angles through a pan-tilt head to ensure full coverage monitoring of the painting area.

[0029] As Figure 3 shown, it also includes an arc-shaped groove 6, which is opened on the bottom wall of the machine box 3, and the arc-shaped groove 6 surrounds the machine box 3 at the center position. The arc-shaped groove 6 is slidably connected with the protective cover 9.

[0030] The protective cover 9 realizes flexible shielding and exposure of the lens of the camera 8 by using the sliding connection with the machine box 3 through the arc-shaped groove 6, so that the protective cover 9 can be completely stored inside the machine box 3 when not needed, without affecting the shooting field of view of the camera 8; and can be quickly unfolded when needed to fully wrap the camera 8 body to provide effective protection.

[0031] As Figure 4 shown, two coaxially and symmetrically distributed rotating seats 11 are provided on the protective cover 9; it also includes a fixed seat 12, which is fixed inside the machine box 3. A rotating shaft 13 is vertically and fixedly connected to a side wall of the machine box 3, and the rotating shaft 13 is rotatably connected with one of the rotating seats 11; it also includes a motor 10, which is fixed inside the machine box 3 and is arranged opposite to the fixed seat 12. The output end of the motor 10 is fixedly connected with the other rotating seat 11 for driving the protective cover 9 to rotate.

[0032] The motor 10 makes the opening and closing process of the protective cover 9 more automated and efficient. Through the drive of the motor 10 and the precise cooperation with the rotating shaft 13 and the rotating seat 11, the protective cover 9 can complete the opening and closing actions in a short time without manual intervention, improving the convenience of the operation.

[0033] As Figure 2 shown, it also includes a fixing block 7, which is arranged on the inner bottom wall of the machine box 3 at the opening position of the arc-shaped groove 6 for limiting the rotation of the protective cover 9.

[0034] By providing the fixing block 7, the stability and reliability of the rotation of the protective cover 9 are further enhanced. When the protective cover 9 rotates to a specific position, the fixing block 7 will play a limiting role to prevent the protective cover 9 from rotating excessively or loosening.

[0035] The protective cover 9 is configured to be completely retracted into the box 3 when the camera 8 is shooting, so as not to block the shooting angle of the camera 8, and the protective cover 9 completely wraps the camera 8 body. During the rotation of the protective cover 9, its inner wall will not collide with the camera 8 body, thereby ensuring the normal rotation of the protective cover 9.

[0036] The technical solution provided by the utility model, in the actual painting work of the drone, first confirm that the battery of the drone body 1 is fully charged, the paint reserve of the spray assembly 4 is sufficient, and the paint delivery system (such as an external gear pump, a metering device, and a feed pipe) has been correctly connected and debugged, check whether the 4K high-resolution camera of the camera 8 is clean, whether the gimbal is working properly, and ensure that it can be adjusted at multiple angles; ensure that the protective cover 9 is in a completely stored state, that is, it is completely located inside the machine box 3 and does not affect the field of view of the camera 8; then, control the drone body 1 to take off through a remote control or a preset program, and fly to the sky above the predetermined painting area; use the drone's own GPS or visual positioning system for precise positioning, ensure that the drone stably hovers above the painting area, activate the camera 8, and use the 4K high-resolution camera and gimbal function to adjust the painting area The drone can monitor the ground conditions in all directions and at multiple angles to ensure that the ground conditions before painting are clearly visible. The drone's position and height are adjusted according to the monitoring screen to obtain the best viewing angle and range for painting. The drone can also process data based on the captured image and the pre-made image to automatically plan the drone's painting path. When painting begins, the drone can fly according to the painting path. During the flight, the motor 10 is started through a preset program to drive the protective cover 9 to quickly unfold and cover the lens area of the camera 8. At the same time, the spraying component 4 is started to process the paint evenly onto the ground. During the painting process, when the drone flies a predetermined range (for example, 30 meters), the drone hovers and the spraying component 4 is temporarily closed. After waiting for 5 seconds, the motor 10 drives the protective cover 9 to be retracted into the machine box 3. The painting area is photographed by the camera 8, and the subsequent flight trajectory is calibrated by comparing the pre-painting image.

[0037] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
