[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: an image acquisition device for drone inspection, comprising a drone body 1; to solve the problem that traditional bolt fixing methods are difficult to install and disassemble when the image acquisition component may need to be replaced before drone takeoff, for convenient charging of the image acquisition component or replacement of the lens. An installation plate 2 is fixedly installed at the bottom of the drone body 1, a balance bracket 3 is snapped onto the bottom of the installation plate 2, and an image acquisition component 4 is installed on the balance bracket 3. The bottom of the installation plate 2 is provided with an installation mechanism 5 and a protection mechanism 6. The installation mechanism 5 allows for convenient installation or disassembly of the balance bracket 3 and the image acquisition component 4, facilitating timely replacement of the image acquisition component 4 and convenient charging of the drone and the image acquisition component 4. The protection mechanism 6 protects the image acquisition component 4 during drone flight and landing, preventing it from being damaged by collisions with obstacles below.
[0023] The mounting mechanism 5 includes a balance bracket plate 501 and a mounting slot 502. The balance bracket plate 501 is fixedly mounted on the top of the balance bracket 3, and the mounting slot 502 is fixedly mounted on the bottom of the mounting plate 2. The balance bracket plate 501 is slidably mounted in the mounting slot 502. Rotary buckles 503 are rotatably mounted on both sides of the mounting slot 502. The two rotating buckles 503 are in contact with the balance bracket plate 501 respectively. Two rotating shafts 509 are fixedly mounted on the bottom of the mounting plate 2. The two rotating shafts 509 are located on both sides of the mounting slot 502 respectively. The two rotating buckles 503 are rotatably mounted on the corresponding rotating shafts 509 respectively. A torsion spring 510 is sleeved on the rotating shaft 509. One end of the torsion spring 510 is fixedly mounted on the rotating shaft 509, and the other end of the torsion spring 510 is fixedly mounted on the rotating buckle 503. During installation, after the balance bracket plate 501 is inserted into the mounting slot 502, the rotating buckles 503 on both sides of the mounting slot 502 will lock the end of the balance bracket plate 501 under the action of the torsion spring 510, thus forming a preliminary fixation.
[0024] A limiting plate 504 is slidably installed on one side of the mounting slot 502. A limiting telescopic component 505 is provided on the other side of the limiting plate 504. The limiting telescopic component 505 is installed at the bottom of the mounting plate 2. A sliding groove 506 is formed within the limiting telescopic component 505. A compression spring 507 and a connecting rod 508 are slidably installed within the sliding groove 506. The other end of the connecting rod 508 is installed on the limiting plate 504. One end of the compression spring 507 is fixedly installed on the connecting rod 508, and the other end is fixedly installed on the inner wall of the sliding groove 506. After the rotating buckle 503 locks the end of the balance bracket plate 501, the limiting plate 504 is slid to both sides of the two rotating buckles 503, limiting the rotation range of the rotating buckles 503 and further fixing them, preventing the balance bracket plate 501 from detaching from the mounting slot 502.
[0025] Example 2: As Figure 4 and 5 The protection mechanism 6 includes four support columns 601, all fixedly installed at the bottom of the mounting plate 2. A common anti-collision plate 602 is mounted on the bottom of the four support columns 601. The anti-collision plate 602 is located directly below the balance bracket 3 and the image acquisition assembly 4. A movable groove 603 is formed within each support column 601. A buffer spring 604 and a sliding rod 605 are slidably installed within the movable groove 603. One end of the buffer spring 604 is fixedly installed on the inner wall of the movable groove 603, and the other end is fixedly installed on the sliding rod 605. The other end of the sliding rod 605 is fixedly installed on the anti-collision plate 602. The anti-collision plate 602 protects the image acquisition assembly 4. When the anti-collision plate 602 comes into contact with an obstacle, the buffer spring 604 provides cushioning to prevent direct collision. The remaining features are the same as in Embodiment 1.
[0026] The working principle is as follows: When installing the balance bracket 3 and the image acquisition component 4, align the balance bracket clamping plate 501 with the mounting slot 502, and slide the limiting plate 504 backward to separate the limiting plate 504 from the rotating buckle 503, releasing the limiting of the rotating buckle 503. The balance bracket clamping plate 501 is then inserted into the mounting slot 502. Under the action of the torsion spring 510, the rotating buckle 503 locks the end of the balance bracket clamping plate 501. Then, the limiting plate 504 is released, allowing it to be fitted onto both sides of the rotating buckle 503 under the action of the limiting telescopic component 505, preventing the rotating buckle 503 from rotating and fixing the balance bracket clamping plate 501 in the mounting slot 502. During the flight and landing of the UAV body 1, the anti-collision plate 602 protects the image acquisition component 4. When the anti-collision plate 602 comes into contact with an obstacle, the buffer spring 604 provides cushioning to prevent direct collision.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
