Description

Technical Field

[0001] This utility model relates to the field of drone camera cleaning technology, specifically a drone remote sensing camera cleaning device. Background Technology

[0002] With the widespread application of UAV remote sensing technology in fields such as agricultural plant protection, geological exploration, environmental monitoring, and power line inspection, the remote sensing camera, as the core component for UAVs to acquire environmental images and data, directly determines the accuracy of subsequent data analysis and the reliability of application decisions based on its imaging quality. In actual operation scenarios, UAVs often need to fly for extended periods in complex field environments, and camera lenses are susceptible to interference from various types of pollutants, including: solid impurities such as dust and soil particles in the field; pesticide droplet residues in agricultural operations; liquid stains formed by water vapor condensation after water operations; and sticky pollutants such as oil and dust mixtures in industrial inspection scenarios.

[0003] Current mainstream cleaning methods still rely on manually disassembling the camera or manually cleaning the lens with a cloth after the drone operation is completed. This method cannot address lens contamination issues in real time during the operation. If lens contamination occurs suddenly during the operation, the flight mission must be interrupted and the drone recalled for cleaning. This not only leads to a significant decrease in operational efficiency but may also result in missing critical data collection opportunities due to mission interruption and the ineffectiveness of manual cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning device for drone remote sensing cameras. By incorporating a wet cleaning component and a water absorption component, the device can clean the lens of the camera body, solving the problems of traditional methods that require recalling the drone for cleaning and the poor cleaning effect.

[0005] To address the problems of existing technologies, this utility model provides a cleaning device for a drone remote sensing camera. The device comprises a drone body, a camera bracket at the bottom of the drone body, a camera body at the bottom of the camera bracket, and a cleaning component for the lens of the camera body. The cleaning component includes a wet cleaning component and a water absorption component mounted on one side of the camera bracket, and also includes a liquid supply component mounted on the camera body.

[0006] Preferably, the wet cleaning assembly includes a first connecting frame that can reciprocate towards or away from the camera body, and a first housing is rotatably mounted on the first connecting frame, and a detachable fiber cloth is mounted on the first housing.

[0007] Preferably, the wet cleaning assembly further includes a first rotary drive member mounted on the side of the first connecting frame away from the first housing, and the output end of the first rotary drive member is connected to the first housing.

[0008] Preferably, the wet cleaning assembly further includes a first fixing bracket fixed on the camera bracket, and a first telescopic drive component is connected to the first fixing bracket, the output end of the first telescopic drive component being connected to the first connecting bracket.

[0009] Preferably, the water-absorbing component includes a second connecting frame that can reciprocate towards or away from the lens of the camera body, and a second housing is rotatably mounted on the second connecting frame, and a detachable water-absorbing cloth is mounted on the second housing.

[0010] Preferably, the water-absorbing assembly further includes a second rotary drive member mounted on the second connecting frame on the side away from the second housing, and the output end of the second rotary drive member is connected to the second housing.

[0011] Preferably, the water absorption assembly further includes a second fixing frame fixed on the camera bracket, and a second telescopic drive component is connected to the second fixing frame, the output end of the second telescopic drive component being connected to the second connecting frame.

[0012] Preferably, the liquid supply assembly includes a clamp mounted on the camera bracket, and a third connecting bracket is fixed on the clamp. A liquid tank is provided on the third connecting bracket. A hose is connected to the bottom of the liquid tank, and a solenoid valve is also connected to the hose. One end of the hose extends to the wet cleaning assembly and is connected to a nozzle that can spray the cleaning liquid inside the liquid tank onto the lens of the camera body.

[0013] The advantages of this utility model compared to the prior art are:

[0014] This application achieves efficient cleaning of the camera lens by constructing a collaborative working mechanism between a wet cleaning component and a water absorption component. In the dirt removal stage, the wet cleaning component uses a fiber cloth as the core cleaning actuator, first bringing the fiber cloth into contact with the lens surface of the camera body; then, the first rotary drive component is activated and outputs rotational power, driving the first housing to rotate around the central axis of the lens, and the fiber cloth rotates and wipes synchronously with the first housing; at the same time, the nozzle sprays cleaning fluid into the contact area between the fiber cloth and the camera lens, which can soften and decompose stubborn dirt adhering to the lens surface. Combined with the rotational wiping force of the fiber cloth, the dirt is peeled off and removed, preventing dirt from remaining on the lens surface due to excessive adhesion. During the water stain removal stage, after the wet cleaning component completes the dirt removal, the microfiber cloth detaches from the lens area of ​​the camera body. Subsequently, the absorbent cloth in the water absorption component moves to the front of the lens and adheres to the lens surface. The absorbent cloth, through its rotation and high absorbency, quickly absorbs any remaining water stains on the lens surface, effectively preventing the formation of a water film or residual water droplets. This prevents issues such as glare, ghosting, and image quality degradation during subsequent imaging. This collaborative solution, through a continuous process of "wet wiping to remove dirt - liquid spraying for cleaning - drying and absorbent lens protection," solves the problem of incomplete removal of stubborn dirt in existing cleaning methods and eliminates the technical pain point of residual water stains on the lens after cleaning. It significantly improves the cleaning effect of the camera lens and the stability of the image quality after cleaning. Attached Figure Description

[0021] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-5 As shown, this utility model provides a drone remote sensing camera cleaning device, including a drone body 1, a camera bracket 2 at the bottom of the drone body 1, a camera body 3 at the bottom of the camera bracket 2, and a cleaning component 4 on the camera bracket 2 capable of cleaning the lens of the camera body 3. The cleaning component 4 includes a wet cleaning component 41 and a water absorption component 42 installed on one side of the camera bracket 2, and a liquid supply component 43 installed on the camera body 3.

[0023] The drone body 1 flies to the target area, and the camera bracket 2 fixes the camera body 3, so that its lens is aimed at the target shooting range. The camera body 3 normally collects remote sensing image data. When the lens of the camera body 3 is contaminated with contaminants (such as dust, water droplets condensed from fog), causing a decrease in image quality, the liquid supply component 43 delivers cleaning liquid to the lens surface through the pipe in a metered manner, so that the lens contaminants are wetted by the cleaning liquid. The wet cleaning component 41 is close to the lens surface to remove the wetted contaminants. After the wet cleaning is completed, the water absorption component 42 is activated, and it is in contact with the lens surface to absorb the residual cleaning liquid until the lens surface is completely dry to avoid water marks.

[0024] The wet cleaning assembly 41 includes a first connecting frame 413 capable of reciprocating towards or away from the lens of the camera body 3, and a first housing 414 rotatably mounted on the first connecting frame 413, with a detachable fiber cloth 416 mounted on the first housing 414. The wet cleaning assembly 41 also includes a first rotary drive 415 mounted on the first connecting frame 413 on the side away from the first housing 414, and the output end of the first rotary drive 415 is connected to the first housing 414.

[0025] During actual cleaning, the first connecting frame 413 first moves the entire structure closer to the lens. After the cleaning fluid supplied by the liquid supply component 43 soaks the fiber cloth 416, the first rotating drive component 415 is activated, driving the first housing 414 and the fiber cloth 416 to rotate. Through the rotational friction of the fiber cloth 416 and the dissolving effect of the cleaning fluid, the wet cleaning of the lens surface is completed. After cleaning, the first connecting frame 413 moves all components away from the lens, waiting for the next cleaning instruction.

[0026] The wet cleaning assembly 41 also includes a first mounting bracket 411 fixed on the camera bracket 2, and a first telescopic drive member 412 is connected to the first mounting bracket 411. The output end of the first telescopic drive member 412 is connected to the first connecting bracket 413.

[0027] When a cleaning instruction is received, the first telescopic drive 412 extends, pushing the first connecting frame 413 toward the lens until the fiber cloth 416 adheres to the lens surface; after cleaning is completed, the first telescopic drive 412 retracts, pulling the first connecting frame 413 and related wiping components away from the lens and returning to the initial standby position to avoid obstructing the lens or interfering with shooting.

[0028] The liquid supply assembly 43 includes a clamp 431 mounted on the camera bracket 2, which serves as the basic fixing structure for the liquid supply assembly 43. It is mounted on the camera bracket 2 and is securely connected to the camera bracket 2 by means of a ring or a snap. A third connecting bracket 432 is fixed on the clamp 431. A liquid tank 433 is provided on the third connecting bracket 432. A hose 434 is connected to the bottom of the liquid tank 433, and a solenoid valve is also connected to the hose 434. One end of the hose 434 extends to the wet cleaning assembly 41 and is connected to a nozzle 435 that can spray the cleaning liquid inside the liquid tank 433 onto the lens of the camera body 3.

[0029] The clamp 431 and the third connecting bracket 432 together fix the liquid tank 433 in a suitable position. The cleaning fluid stored in the liquid tank 433 is ready to be used through the hose 434 at the bottom. When the wet cleaning component 41 needs cleaning fluid, the control system (generally the control system of a drone, which is existing technology) triggers the solenoid valve to open. The cleaning fluid flows along the hose 434 under the action of gravity and is finally sprayed onto the fiber cloth 416 through the nozzle 435. This provides liquid support for the rotating wiping action of the wet cleaning component 41 and ensures the lens cleaning effect.

[0030] The water-absorbing assembly 42 includes a second connecting frame 423 capable of reciprocating towards or away from the lens of the camera body 3, and a second housing 424 rotatably mounted on the second connecting frame 423, with a detachable absorbent cloth 426 mounted on the second housing 424. The water-absorbing assembly 42 also includes a second rotary drive member 425 mounted on the second connecting frame 423 on the side away from the second housing 424, and the output end of the second rotary drive member 425 is connected to the second housing 424.

[0031] The operation of the water-absorbing component 42 is connected with that of the wet cleaning component 41: after the wet cleaning component 41 finishes wiping the lens, the second connecting bracket 423 drives the entire structure to move closer to the lens until the absorbent cloth 426 adheres to the lens surface; then the second rotating drive component 425 is activated, driving the second housing 424 and the absorbent cloth 426 to rotate, and through rotational friction and the water absorption of the materials, the residual liquid on the lens is completely absorbed; after the water absorption is completed, the second connecting bracket 423 drives all components away from the lens to reset, clearing obstacles for the normal shooting of the camera body 3, and finally achieving a complete cleaning closed loop of "wet cleaning - drying finishing".

[0032] The water absorption assembly 42 also includes a second fixing bracket 421 fixed on the camera bracket 2, and a second telescopic drive member 422 is connected to the second fixing bracket 421. The output end of the second telescopic drive member 422 is connected to the second connecting bracket 423.

[0033] After the wet cleaning component 41 finishes wiping, the second telescopic drive component 422 receives the instruction and extends, pushing the second connecting bracket 423 to move towards the lens until the absorbent cloth 426 is tightly attached to the lens surface; after the water absorption is completed, the second telescopic drive component 422 retracts and pulls the second connecting bracket 423 and related components away from the lens, returning to the initial standby position to avoid obstructing the lens or affecting subsequent remote sensing shooting.

[0034] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
