It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments.
[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0025] A self-cleaning aerial surveying and mapping device for unmanned aerial vehicles (UAVs) includes: a main body 100, with four sets of flight propellers 110 on the top of the main body 100 for flight movement; a camera 200, located at the bottom of the main body 100, with a protective frame 210 covering the outer surface of the camera 200, the bottom of the protective frame 210 being transparent; a cleaning component 300, located at the bottom of the protective frame 210, for cleaning the bottom surface of the protective frame 210; and a spraying component 400, located on both sides of the bottom of the protective frame 210, for cooperating with the cleaning component 300 to spray and wash the bottom surface of the protective frame 210. The main body 100 provides lift and power through the rotation of four sets of flight propellers 110 at the top, enabling the drone to fly and move. The camera 200 at the bottom of the main body is responsible for aerial surveying and mapping. The protective frame 210 protects the camera, and its transparent bottom does not affect the camera's field of view. When the bottom surface of the protective frame is covered with stains that affect the shooting, the spray assembly 400 first sprays and washes the bottom surface, and then the cleaning assembly 300 further cleans the bottom surface to ensure the cleanliness of the transparent bottom surface. During operation, the flight propeller 110, camera 200, cleaning component 300 and spray component 400 are all connected and controlled by the internal circuit of the main body 100, which is a conventional technology in the field of drones and their accessories.
[0026] The cleaning component 300 includes: a drive groove 310 formed on both sides of the bottom of the protective frame 210, with a drive block 311 slidably connected inside the drive groove 310; a drive motor 312 provided on the inner wall of one side of the drive groove 310, with a drive rod 313 connected to one side of the drive motor 312, and the drive rod 313 and the drive block 311 being threadedly engaged; a sliding groove 320 formed on both sides of the bottom of the protective frame 210, with a slider 321 provided inside the sliding groove 320; and a scraper 330 provided between the slider 321 and the drive block 311, the scraper 330 being inclined and its edge abutting against the bottom surface of the protective frame 210. The drive motor 312 inside the drive groove 310 is started, and the drive motor drives the drive rod 313 to rotate. Since the drive rod is threadedly engaged with the drive block 311, the drive block slides linearly along the drive groove. When the drive block moves, it drives the scraper 330 to move synchronously. The other end of the scraper slides along the slide groove 320 through the slider 321 to achieve guidance and support. The inclined scraper edge is in close contact with the bottom surface of the protective frame 210, and removes the stains on the bottom surface during the movement.
[0027] The slide groove 320 is equipped with a guide rail 322, and the guide rail 322 is slidably connected to the slider 321. When the scraper 330 drives the slider 321 to slide along the slide groove 320, the slider moves in a directional manner along the guide rail 322, and the guide rail restricts and guides the movement trajectory of the slider.
[0028] The spray assembly 400 includes: liquid storage chambers 410 on both sides of the protective frame 210, a pump 411 at the bottom of the liquid storage chambers 410, and a pump pipe 412 connected to the bottom of the pump 411; spray plates 420 on both sides of the bottom of the protective frame 210, a diversion net 421 inside the spray plate 420, and the pump pipe 412 having multiple openings on the diversion net 421 for diverting cleaning liquid onto the diversion net 421; and multiple blowers 422 at the bottom of the spray plate 420, with the blower outlets facing the diversion net 421. The cleaning fluid in the storage chamber 410 is drawn by the pump 411 and transported to the distribution net 421 in the spray plate 420 through the pump pipe 412. The pump pipe is located in multiple openings on the distribution net to evenly distribute the cleaning fluid to the distribution net. The blower 422 is started, and its air outlet blows air towards the distribution net 421, blowing the cleaning fluid on the distribution net 421 toward the bottom surface of the protective frame 210 to realize the spraying action.
[0029] The diversion mesh 421 consists of two layers of filter screens with a gap between them. After the cleaning liquid flows out through the opening of the pump pipe 412, it first contacts the upper filter screen of the diversion mesh 421. After being initially dispersed by the upper filter screen, it is buffered by the gap between the two filter screens and then permeates to the lower filter screen, thus realizing the secondary diversion of the cleaning liquid.
[0030] The blower 422 is set in an inclined structure and is tilted towards the bottom of the protective frame 210. After the blower 422 is started, because it is tilted and set towards the bottom of the protective frame 210, the airflow blown out acts directionally on the bottom surface of the protective frame, and accurately blows the cleaning liquid on the diversion net 421 to the cleaning surface.
[0031] The liquid storage chamber 410 has an injection port on one side of its top for replenishing the liquid. When the amount of cleaning liquid in the liquid storage chamber 410 is insufficient, the cleaning liquid is replenished into the liquid storage chamber through the injection port on one side of the top. After replenishment, it can continue to provide working medium for the spray assembly.
[0032] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
[0033] The above provides a detailed description of a self-cleaning aerial surveying and mapping device for unmanned aerial vehicles (UAVs) provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
