Description

Technical Field

[0001] The present invention belongs to the technical field of camera devices, and in particular relates to a camera device for an unmanned aerial vehicle and a method of using the same. Background Art

[0002] Drone cameras are core components in drone systems, capturing high-quality images or videos in real time. They are widely used in aerial photography, surveying and mapping, agricultural monitoring, search and rescue operations, and other fields. Modern drone cameras typically consist of a lens, image sensor, stabilization system, data transmission module, and control system. The lens is responsible for optical imaging, with wide-angle, telephoto, and zoom lenses being common, catering to diverse scenarios. Image sensors come in two types: CCD and CMOS. The latter is the mainstream choice due to its low power consumption and high integration, offering resolutions ranging from 1080p to 8K, providing ultra-high-definition image quality. Stabilization is crucial, utilizing a mechanical gimbal (three-axis or two-axis) and electronic image stabilization to minimize in-flight jitter and ensure smooth and stable images. Some high-end models also feature lidar or infrared sensors, enabling nighttime photography or operation in challenging environments. The data transmission module transmits images back to a ground station in real time via Wi-Fi, 4G / 5G, or dedicated image transmission technology, with millisecond latency. The control system allows users to remotely adjust parameters such as focus, exposure, and white balance, and some models support AI-powered features such as automatic tracking, object recognition, and obstacle avoidance. To adapt to complex environments, cameras are typically waterproof, dustproof, and windproof, and lightweight to extend flight time. With technological advancements, drone cameras are developing towards higher resolution, greater stability, and intelligent features, providing more efficient solutions for industry applications.

[0021] A method for using a camera device for an unmanned aerial vehicle comprises the following steps:

[0022] S1. A hydrogen peroxide solution and a first catalyst are added to the first reaction chamber, and sodium sulfite and a second catalyst are added to the second reaction chamber. The hydrogen peroxide solution decomposes under the action of the first catalyst and the heating plate to produce water and oxygen. The increase in oxygen increases the pressure in the pressure chamber on the left side of the driving chamber. The water produced by the reaction is stored in the liquid storage chamber through the connecting valve. The sodium sulfite reacting in the second reaction chamber consumes the oxygen in the pressure chamber on the right side of the driving chamber under the action of the second catalyst, and the pressure in the pressure chamber decreases.

[0023] S2. The negative pressure in the right pressure chamber acts on the adsorption frame through the negative pressure channel, causing the adsorption frame to be adsorbed on the lower surface of the drone body;

[0024] S3. Control the operation of the drone body to make it fly to the target location and shoot the environment to be shot. During the shooting process, the two first control valves are controlled to operate respectively. The positive pressure and negative pressure in the two pressure chambers enter the drive chamber respectively. When the positive pressure enters the drive chamber, the third control valve opens. The positive pressure pushes the push rod to slide in the mounting block. The push rod drives the camera to adjust the angle through the rotating block and the limit slider;

[0025] S4. When dust in the environment adheres to the lens surface of the camera, the negative pressure in the right pressure chamber acts on the drive chamber, driving the push rod to slide in the mounting block, causing the camera lens to contact the cleaning cotton. The pump body pumps water in the liquid storage chamber through the second infusion channel, the first infusion channel, the rotating tube, and the liquid dispersion channel into the lens surface of the camera. The pump then controls the operation of the first motor, indirectly driving the cleaning cotton to rotate, thereby cleaning the camera lens;

[0026] S5. Then, the positive pressure in the pressure chamber on the left side is continued to enter the driving chamber, indirectly driving the camera to adjust the angle and continue shooting.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. In the present invention, by using this device, when a camera is used to shoot in an environment with a lot of smoke and dust, the smoke and dust in the environment adhere to the lens surface of the camera, and the first motor is controlled to operate, indirectly driving the cleaning cotton to rotate. When the cleaning cotton rotates, the lens of the camera is cleaned, and the dust on the lens is removed in time to ensure the shooting effect of the camera.

[0029] 2. In the present invention, the adsorption frame and the camera are moved by controlling the drone body. After moving to the position where the camera needs to be photographed, the environment is photographed by adjusting the angle of the camera.

[0030] 3. In the present invention, the second reaction chamber is used for sodium sulfite reaction, and the negative pressure channel is adsorbed on the lower surface of the drone body through the adsorption frame. When the adsorption frame needs to be removed, the second control valve is controlled to open to release the pressure in the negative pressure channel to complete the disassembly.

10. A method for using a camera device for a drone, using the camera device for a drone according to any one of claims 1 to 9, characterized in that: The steps include: S1. A hydrogen peroxide solution and a first catalyst are added to the first reaction chamber (503), and sodium sulfite and a second catalyst are added to the second reaction chamber (507). The hydrogen peroxide solution decomposes under the action of the first catalyst and the heating plate to produce water and oxygen. The increase in oxygen increases the pressure in the pressure chamber (502) located on the left side of the driving chamber (5). The water produced by the reaction is opened through the connecting valve (504) and stored in the liquid storage chamber (505). The sodium sulfite reacting in the second reaction chamber (507) consumes the oxygen in the pressure chamber (502) on the right side of the driving chamber (5) under the action of the second catalyst, and the pressure in the pressure chamber (502) decreases. S2. The negative pressure in the right pressure chamber (502) acts on the adsorption frame (2) through the negative pressure channel (508), causing the adsorption frame (2) to be adsorbed on the lower surface of the drone body (1); S3, controlling the operation of the drone body (1) to make the drone body (1) fly to the target position and shoot the environment to be shot. During the shooting process, the two first control valves (501) are controlled to operate respectively, and the positive pressure and negative pressure in the two pressure chambers (502) enter the driving chamber (5) respectively. When the positive pressure enters the driving chamber (5), the third control valve (601) opens, and the positive pressure pushes the push rod (6) to slide in the mounting block (3). The push rod (6) drives the camera (302) to adjust the angle through the rotating block (602) and the limit slider (603); S4. When dust in the environment adheres to the lens surface of the camera (302), the negative pressure in the right pressure chamber (502) acts on the driving chamber (5), driving the push rod (6) to slide in the mounting block (3), so that the lens of the camera (302) contacts the cleaning cotton (402). The pump body (506) transfers the water in the liquid storage chamber (505) through the second infusion channel (410), the first infusion channel (409), the rotating tube (403) and the liquid dispersion channel (408) into the lens surface of the camera (302). Subsequently, the first motor (406) is controlled to operate, indirectly driving the cleaning cotton (402) to rotate, and the lens of the camera (302) is cleaned under the rotation of the cleaning cotton (402); S5. Then, the positive pressure in the left pressure chamber (502) is continuously allowed to enter the driving chamber (5), thereby indirectly driving the camera (302) to adjust its angle and continue shooting.
