Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) surveying and mapping, and in particular to a surveying UAV with lens protection function. Background Technology

[0002] Surveying drones are tools that use drones as a platform, equipped with sensors and photographic equipment to collect geographic information. They are small and flexible, capable of taking off and landing in complex environments, and equipped with high-precision GPS and advanced cameras to acquire high-resolution surface data. Compared to traditional surveying, they are lower in cost and more efficient, and are widely used in fields such as topographic surveying, urban planning, and agricultural monitoring. However, existing drones are susceptible to damage during surveying due to extreme weather conditions, which can cause foreign objects to scratch and damage the lens, or damage to the surveying lens after a drone crash.

[0003] Therefore, it is necessary to provide a new mapping drone with lens protection function to solve the above-mentioned technical problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a mapping drone with lens protection function is provided to solve the above problems.

[0005] The mapping drone with lens protection function provided by this utility model includes: a drone, a gimbal fixedly connected to the bottom of the drone, a camera connected to one side of the gimbal, protective plates fixedly connected to both sides of the gimbal, a top plate connected to the top of the two protective plates, a movable groove opened on one side of the top plate, a connecting shaft fixedly connected inside the movable groove, a limit block fixedly connected to the outer wall of the connecting shaft, a T-slot opened on one side of the limit block, a T-block provided on one side of the T-slot, a baffle fixedly connected to the T-block on the side away from the movable groove, a turntable rotatably connected to the protective plate on the side of the gimbal, and a connecting rod fixedly connected to the bottom of the turntable.

[0006] Preferably, both protective plates are fixedly connected to fixed rods on the side away from the gimbal, and movable rods are movably connected inside both fixed rods. Springs are directly fixedly connected to the bottom of the two movable rods on the lower inner surface of each fixed rod. Rotating rods are connected to opposite sides of the two movable rods, and rotating cylinders are sleeved on the outer side of the rotating rods.

[0007] Preferably, a motor is fixedly connected to one side of the protective plate, and the motor is fixedly connected to the turntable through its output end.

[0008] Preferably, the bottom of the connecting rod is rotatably connected to one side of the baffle.

[0009] Preferably, the baffle is made of a transparent material.

[0010] Preferably, the T-shaped block slides along the inside of the T-shaped groove.

[0011] Compared with related technologies, the mapping drone with lens protection function provided by this utility model has the following beneficial effects:

[0012] When in use, the motor is started, which drives the turntable to rotate. The turntable drives the connecting rod to rotate, and at the same time pushes the baffle upward. The baffle drives the T-block to move synchronously. The T-block drives the baffle upward along the T-slot, while the limit block rotates around the connecting shaft. When the connecting rod rotates to the top, the baffle covers the top surface. The opening and closing of the baffle prevents the lens from being damaged by foreign objects and also prevents the lens from breaking in the event of a crash.

[0013] When the baffle rotates upward, it lifts the rotating shaft, and the rotating cylinder drives the central rotating rod to move upward. The top of the baffle pushes the rotating cylinder to rotate around the rotating rod through friction. At the same time, the rotating rod drives the two movable rods to move upward, stretching the spring. Under the contraction force generated by the spring, the rotating cylinder is pressed tightly against the surface of the baffle and cleaned by the brush. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] Please see Figures 1 to 4 This utility model provides a surveying drone with lens protection function. The surveying drone with lens protection function includes: drone 1, gimbal 2 fixedly connected to the bottom of drone 1, camera 3 connected to one side of gimbal 2, protective plates 4 fixedly connected to both sides of gimbal 2, top plate 5 connected to the top of the two protective plates 4, movable groove 6 opened on one side of top plate 5, connecting shaft 7 fixedly connected inside movable groove 6, limit block 8 fixedly connected to the outer wall of connecting shaft 7, T-slot 9 opened on one side of limit block 8, T-block 10 set on one side of T-slot 9, baffle 11 fixedly connected to the side of T-block 10 away from movable groove 6, turntable 12 rotatably connected to the side of protective plate 4 on gimbal 2, connecting rod 13 fixedly connected to the bottom of turntable 12, motor 19 fixedly connected to one side of protective plate 4, motor 19 fixedly connected to turntable 12 through output end, bottom of connecting rod 13 rotatably connected to one side of baffle 11, and T-block 10 sliding along the inside of T-slot 9.

[0023] It should be noted that: UAV 1 is the carrier of the entire system, providing a platform for the gimbal 2, camera 3, and other auxiliary structures. The gimbal 2 has high-precision rotation capabilities, accurately adjusting the shooting angle of camera 3. Camera 3, as the core surveying equipment, provides high-quality data for surveying work. Two protective plates 4 provide protection for the gimbal 2 and camera 3, blocking external collisions and impacts from foreign objects, protecting the internal precision structure. The top plate 5 and the protective plates 4 together form a protective frame, enhancing the overall stability and protective capability of the structure. The movable groove 6 is the mounting point for the connecting shaft 7, determining its position and providing a track for the movement of the limit block 8, allowing related components to move according to the designed trajectory. The connecting shaft 7 is fixed in the movable groove 6, providing a rotation center for the limit block 8, ensuring that the limit block 8 can rotate stably around it. The limit block 8 cooperates with the T-slot 9 and T-block 10 to limit the movement range of the T-block 10, ensuring the positional accuracy of the baffle 11 when it opens and closes, and preventing excessive movement that could damage or affect the protective function. For protection, the T-slot 9 cooperates with the T-block 10 to guide the movement of the T-block 10, ensuring smooth opening and closing of the baffle 11. When the motor 19 drives the turntable 12 to rotate, it ensures the accuracy and consistency of the baffle 11's movement. The T-block 10 connects the baffle 11 and the limiting block 8, sliding within the T-slot 9 to convert the power transmitted from the turntable 12 via the connecting rod 13 into the opening and closing movement of the baffle 11, thus enabling the blocking and exposure of the camera lens. When closed, the baffle 11 effectively blocks dust. Dust and foreign objects are removed to protect the lens of camera 3. When open, the shooting field of view of camera 3 is not affected, ensuring normal shooting. Turntable 12 rotates precisely under the drive of motor 19. The rotational motion is transmitted to baffle 11 through connecting rod 13, realizing the flexible opening and closing of baffle 11. Connecting rod 13 connects turntable 12 and baffle 11, converting the rotational motion of turntable 12 into the opening and closing motion of baffle 11. Motor 19, as the driving source, provides power for the rotation of turntable 12, realizing the opening and closing control of baffle 11.

[0024] In the embodiment of this utility model, two protective plates 4 are fixedly connected to fixed rods 14 on the side away from the gimbal 2. Movable rods 15 are movably connected inside the two fixed rods 14. Springs 16 are directly fixedly connected to the bottom of the two movable rods 15 on the lower inner surface of the two fixed rods 14. Rotating rods 17 are connected to the opposite side of the two movable rods 15. A rotating cylinder 18 is sleeved on the outside of the rotating rod 17.

[0025] It should be noted that the fixed rod 14 has a hollow internal structure, creating space for the movement of the movable rod 15 and guiding its up-and-down movement. It also provides installation space for the spring 16. The movable rod 15 can move up and down within the fixed rod 14. Simultaneously, the opposite side of the movable rod 15 is connected to the rotating rod 17, converting the spring's buffering action into support and linkage for the rotating rod 17. The spring 16 has one end fixed to the lower inner surface of the fixed rod 14 and the other end connected to the bottom of the movable rod 15. Its main function is to provide elastic contraction force. The rotating rod 17 integrates and transmits the movement of the two movable rods 15, while also providing a support shaft for the rotating drum 18, allowing it to rotate around its circumference. The surface of the rotating drum 18 is covered with a brush, which can clean dust, debris, and other small particles from the baffle 11.

[0026] In an embodiment of this utility model, the baffle 11 is made of transparent material;

[0027] It should be noted that the baffle 11 is made of transparent material. When it is closed, it can effectively block dust and foreign objects, prevent them from contacting the camera lens, protect the lens from contamination and physical damage, and does not affect the shooting field of view.

[0028] The working principle of the surveying drone with lens protection function provided by this utility model is as follows: When in use, the motor 19 is started, the motor 19 drives the turntable 12 to rotate, the turntable 12 drives the connecting rod 13 to rotate, and at the same time pushes the baffle 11 to tilt upward. The baffle 11 drives the T-block 10 to move synchronously. The T-block 10 drives the baffle 11 to move upward along the T-groove 9. At the same time, the limiting block 8 rotates around the connecting shaft 7. When the connecting rod 13 rotates to the top, the baffle 11 covers the upper surface of the top 5. By opening and closing the baffle 11, the lens is prevented from being damaged by foreign objects and also prevents the lens from breaking after a crash.

[0029] When the baffle 11 rotates upward, the baffle 11 lifts the rotating shaft 18, and the rotating cylinder 18 drives the rotating rod 17 in the middle to move upward. The top of the baffle 11 pushes the rotating cylinder 18 to rotate around the rotating rod 17 through friction. At the same time, the rotating rod 17 drives the two movable rods 15 to move upward, and at the same time stretches the spring 16. Under the contraction force generated by the spring 16, the rotating cylinder 18 is pressed tightly against the surface of the baffle 11 and cleaned by the brush.

[0030] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
