The control and wireless communication module is connected to the motors. A cabin is located at the front of the fuselage, housing an inspection camera. Transparent panels are located on the lower side and both sides of the cabin. This invention extends the field of view to the left, right, and forward at the front camera position without increasing the aircraft's drag coefficient or weight. It offers advantages such as a wide field of view for power line inspection, no increase in drag coefficient or weight, and a simple structure. The inspection camera in the cabin solves the problem of field of view and reduces wind resistance at the camera position, thereby improving the aircraft's range.

[0004] The aforementioned drones have the following problems when in use: it is not convenient to disassemble and replace the camera; after the camera is damaged, special disassembly and assembly tools are required, and professional personnel are needed to disassemble and assemble the camera; users are prone to causing secondary damage to the camera when disassembling and assembling it on their own. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a camera mounting mechanism and a marine inspection vertical take-off fixed-wing UAV, which can realize the quick disassembly and replacement of the camera without damaging the camera.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] On one hand, a camera mounting mechanism is provided, including a camera, a mounting base, a locking component, and a limiting bracket. The mounting base is installed on the bottom of the drone body of a maritime patrol vertical take-off and landing fixed-wing UAV. The camera has a front and a back along a first direction, a top and a bottom along a second direction, and two sides along a third direction. The bottom of the camera is engaged with the mounting base. The locking component is detachably fixed to the mounting base and abuts against the front or back of the camera. The limiting bracket is detachably installed on the mounting base and can fit against the top and two sides of the camera. The first direction, the second direction, and the third direction are perpendicular to each other.

[0008] As a further embodiment of the camera mounting mechanism, the mounting base includes a vertically connected connecting plate and a mounting plate. The camera includes a camera body and a snap-fit ​​protrusion. The snap-fit ​​protrusion protrudes from the bottom surface of the camera body. The mounting base has a slot on one side facing the bottom surface of the camera body. The end of the slot away from the connecting plate along the first direction is open. The snap-fit ​​protrusion is inserted into the slot through the open and snaps into the slot. A locking member is mounted on the mounting plate adjacent to the open, and the locking member abuts against the end of the snap-fit ​​protrusion away from the connecting plate.

[0009] As a further embodiment of the camera mounting mechanism, the locking element includes two abutment pins. The mounting plate has two threaded holes spaced apart on the side opposite to the connecting plate along the first direction. The two threaded holes are respectively adjacent to the opening of the slot. The two abutment pins are screwed into one of the threaded holes until the pin head of the abutment pin abuts against the locking protrusion.

[0010] As a further embodiment of the camera mounting mechanism, the limiting frame includes a first limiting part and two second limiting parts. The length of the first limiting part extends along a third direction, and the two second limiting parts are spaced apart along a third direction on the side of the first limiting part facing the camera body. The first limiting part is in contact with the top surface of the camera body, and the second limiting parts are in contact with the two sides of the camera body. The first limiting part is detachably connected to the connecting plate.

[0011] As a further embodiment of the camera mounting mechanism, it also includes two connecting columns and two pull plates. The length of the connecting columns extends along the first direction. The two connecting columns are fixed at intervals on the connecting plates and located on both sides of the camera along the third direction. The first limiting part is detachably connected to the connecting columns at both ends along the third direction through one of the pull plates.

[0012] On the other hand, a marine inspection vertical take-off fixed-wing UAV is provided, comprising a UAV body, fixed wings, a pylon, and the aforementioned camera mounting mechanism. The two fixed wings are symmetrically mounted on both sides of the UAV body in the horizontal direction. The pylon is fixed to the bottom of the UAV body, and the mounting base of the camera mounting mechanism is detachably mounted on the pylon.

[0013] As a further embodiment of the VTOL fixed-wing UAV for maritime inspection, it also includes a drive mechanism and a rotating shaft. The pylon is an inverted U-shaped structure consisting of a top plate and two side plates. The top plate is fixed to the bottom of the UAV body. The axis of the rotating shaft extends in a third direction. The two ends of the rotating shaft along its axis are rotatably connected to the two side plates. The drive mechanism is mounted on one of the side plates and is connected to the rotating shaft for transmission. The mounting base is detachably connected to the rotating shaft.

[0014] As a further embodiment of the VTOL fixed-wing UAV for maritime inspection, the drive mechanism includes a motor and bearing housings. The motor is fixed to the outside of one of the side plates of the gantry along the third direction. A bearing housing is installed on the inner side of each of the two side plates. One end of the rotating shaft along the third direction passes through one of the bearing housings and the side plate and is connected to the output shaft of the motor, while the other end is connected to the other bearing housing.

[0015] As a further embodiment of the maritime inspection vertical take-off fixed-wing UAV, it also includes two shock absorption mechanisms, one of which is installed on the outer side of each of the two side plates, and the shock absorption mechanism protrudes from the bottom surface of the side plate.

[0016] As a further embodiment of the VTOL fixed-wing UAV for maritime inspection, the shock absorption mechanism includes a mounting box, a shock absorber block, and a fixing block. The mounting box is fixed to the outside of the side plate. The mounting box has a T-shaped stepped hole extending through it in a second direction. The shock absorber block has a T-shaped structure and passes through the T-shaped stepped hole. The fixing block is located inside the T-shaped stepped hole and abuts against the top surface of the shock absorber block. The fixing block is fixedly connected to the mounting box. The bottom surface of the shock absorber block protrudes from the bottom surfaces of the mounting box and the side plate.

[0017] Beneficial effects: The camera mounting structure of this utility model limits the camera from multiple directions. Since the locking parts and the limiting frame can be detached and fixed on the mounting base, and the locking parts and the limiting frame only abut or fit against the surface of the camera, the camera can be disassembled and replaced by releasing the locking parts and removing the limiting frame. The entire disassembly process will not damage the camera. Attached Figure Description

[0026] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationships shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are merely used for distinction in description and have no special meaning.

[0030] like Figure 1 and Figure 2 As shown, this embodiment provides a camera mounting mechanism 100, including a camera 1, a mounting base 2, a locking component, and a limiting frame 3. The mounting base 2 is installed on the bottom of the drone body of a maritime inspection drone. The camera 1 has a front and a back along a first direction (X direction in the figure), a top and a bottom along a second direction (Z direction in the figure), and two opposite sides along a third direction (Y direction in the figure). The bottom surface of the camera 1 is engaged with the mounting base 2. The locking component is detachably fixed on the mounting base 2 and abuts against the front or back of the camera 1. The limiting frame 3 is detachably installed on the mounting base 2 and can fit against the top surface and two sides of the camera 1. The first direction, the second direction, and the third direction are perpendicular to each other.

[0031] It is understood that after the bottom surface of camera 1 is snapped into the mounting base 2, it abuts against the locking component that is detachably fixed to the mounting base 2, thereby limiting the camera 1 in the first direction. The limiting frame 3 is attached to the top surface of camera 1, which can limit the camera 1 in the vertical direction (second direction). The limiting frame 3 is attached to the two opposite sides of camera 1, which can limit the camera 1 in the third direction, thereby stably mounting camera 1 on the mounting base 2. The camera 1 mounting structure of this embodiment limits the camera 1 from multiple directions. Since both the locking component and the limiting frame 3 are detachably fixed to the mounting base 2, and the locking component and the limiting frame 3 only abut or adhere to the surface of camera 1, the camera 1 can be disassembled and replaced by releasing the locking component and removing the limiting frame 3. The entire disassembly process will not damage camera 1.

[0032] Furthermore, the mounting base 2 includes a vertically connected connecting plate 21 and a mounting plate 22. The camera 1 includes a camera body 11 and a snap-fit ​​protrusion 12. The snap-fit ​​protrusion 12 protrudes from the bottom surface of the camera body 11. The mounting plate 22 has a slot 221 on one side facing the bottom surface of the camera body 11. The end of the slot 221 away from the connecting plate 21 along the first direction is open. The snap-fit ​​protrusion 12 can be inserted into the slot 221 through the open and snap-fit ​​with the slot 221. A locking member is installed on the mounting plate 22 adjacent to the open. The locking member abuts against the end of the snap-fit ​​protrusion 12 away from the connecting plate 21.

[0033] In this configuration, the back of the camera 1 faces the connecting plate 21. The snap-fit ​​protrusion 12 is inserted into the slot 221 through the opening to achieve snap-fit. Then, the locking member is installed on the mounting plate 22 so that the locking member abuts against the end of the snap-fit ​​protrusion 12 away from the connecting plate 21, thereby limiting the camera 1 along the first direction.

[0034] For example, along the first direction, the length of the slot 221 is the same as the length of the snap-fit ​​protrusion 12. After the snap-fit ​​protrusion 12 snaps into the slot 221, the end of the snap-fit ​​protrusion 12 away from the connecting plate 21 is flush with the end face of the mounting plate 22.

[0035] Preferably, the locking element includes two abutment pins 4. The mounting plate 22 has two threaded holes 222 spaced apart on the side away from the connecting plate 21 along the first direction. The two threaded holes 222 are respectively adjacent to the opening of the slot 221. The two abutment pins 4 are screwed into one of the threaded holes 222 until the pin head of the abutment pin 4 abuts against the locking protrusion 12.

[0036] In this embodiment, after the pin of the abutment pin 4 is screwed and fixed to the threaded hole 222, the pin head of the abutment pin 4 (T-shaped structure, the pin head diameter is larger than the pin rod) simultaneously abuts against the end of the snap-fit ​​protrusion 12 away from the connecting plate 21 in the first direction, thereby limiting the camera 1 in the first direction.

[0037] Specifically, in this embodiment, the snap-fit ​​protrusion 12 has an inverted T-shaped structure, and correspondingly, the slot 221 has an inverted T-shaped structure. Two threaded holes 222 are symmetrically arranged on the side of the mounting plate 22 away from the connecting plate 21 along the first direction and adjacent to the two sides of the slot 221 opening along the third direction. After the snap-fit ​​protrusion 12 is inserted into the slot 221 through the opening, the abutment pin 4 is screwed into the corresponding threaded hole 222, so that the pin head of the abutment pin 4 (the abutment pin 4 has a T-shaped structure, and the size of the pin head is larger than the size of the pin body) abuts against the end face of the snap-fit ​​protrusion 12 along the first direction, preventing the snap-fit ​​protrusion 12 from slipping out of the slot 221. Since there is an assembly gap between the snap-fit ​​protrusion 12 and the slot wall of the slot 221, the camera body 11 can be limited along the second direction and the third direction by the limiting bracket 3, so as to avoid the camera body 11 from shaking due to the assembly gap and affecting the image quality.

[0038] In this embodiment, there is a gap between the camera 1 and the connecting plate 21 to facilitate cable routing.

[0039] Furthermore, the limiting frame 3 includes a first limiting part 31 and two second limiting parts 32. The length of the first limiting part 31 extends along a third direction, and the two second limiting parts 32 are spaced apart along a third direction on the side of the first limiting part 31 facing the camera body 11. The first limiting part 31 is attached to the top surface of the camera body 11, so that the camera 1 can be pressed against the mounting plate 22 and the first limiting part 31 in a second direction. The second limiting parts 32 are attached to the two sides of the camera body 11, so that the camera body 11 can be limited in a second direction. The first limiting part 31 is detachably connected to the connecting plate 21 to facilitate the removal of the limiting frame 3 to remove the camera 1.

[0040] Furthermore, to facilitate the detachable connection between the limiting frame 3 and the mounting plate 22, the camera mounting mechanism 100 of this embodiment also includes two connecting posts 5 and two pull plates 6. The length of the connecting posts 5 extends along the first direction, and the two connecting posts 5 are fixed at intervals on the connecting plate 21 and located on both sides of the camera 1 along the third direction. The two ends of the first limiting part 31 along the third direction are detachably connected to the connecting posts 5 through a pull plate 6. One end of the pull plate 6 is connected to the first limiting part 31 by a screw, and the other end has a connecting hole. The connecting posts 5 are correspondingly provided with threaded connecting holes. A fixing pin 7 is screwed into the threaded connecting hole through the connecting hole, so that the first limiting part 31 is connected to the connecting posts 5 through the pull plate 6, and the connecting posts 5 provide support for the limiting frame 3.

[0041] Preferably, the connecting hole is an oblong hole, the length of which extends along the second direction. After adjusting the position of the limiting bracket 3 so that the limiting bracket 3 is in close contact (fitting) with the top surface and two sides of the camera body 11, the fixing pin 7 is screwed through the oblong hole and screwed into the threaded connecting hole for fixation.

[0042] When it is necessary to disassemble camera 1, first unscrew the fixing pin 7, remove the pull plate 6 and the limit bracket 3 together, and then remove the locking parts so that the snap-fit ​​protrusion 12 of camera 1 can be removed from the slot 221 through the opening. The disassembly process will not damage camera 1.

[0043] like Figure 3 As shown, this embodiment also provides a maritime patrol vertical take-off fixed-wing UAV, comprising a UAV body 200, fixed wings 300, a pylon 400, and a camera mounting mechanism 100 as described in any of the above embodiments. Two fixed wings 300 are symmetrically mounted on both sides of the UAV body 200 in the horizontal direction. The pylon 400 is fixed to the bottom of the UAV body 200, and the mounting base 2 of the camera mounting mechanism 100 is detachably mounted on the pylon 400. By providing fixed wings 300 on the UAV body 200, the fixed wings 300 can generate vertical lift on the UAV body 200 through airflow, reducing propeller energy loss and improving the stability of the UAV body 200 during flight. The camera mounting mechanism 100 is detachably mounted on the pylon 400 for easy assembly and disassembly.

[0044] Furthermore, the maritime inspection vertical take-off fixed-wing UAV of this embodiment also includes a drive mechanism 500 and a rotating shaft 600, such as... Figure 4 As shown, the hanger 400 is an inverted U-shaped structure consisting of a top plate 410 and two side plates 420. The top plate 410 is fixed to the bottom of the UAV body 200. The axis of the rotating shaft 600 extends along a third direction, and both ends of the rotating shaft 600 are rotatably connected to the two side plates 420 along its axis. The drive mechanism 500 is mounted on one of the side plates 420 and is connected to the rotating shaft 600 for transmission. The mounting base 2 is detachably connected to the rotating shaft 600. With this structural design, the rotating shaft 600 can be driven by the drive mechanism 500 to rotate the mounting base 2 and the camera 1 around the axis of the rotating shaft 600, thereby achieving angle adjustment of the camera 1. Furthermore, the detachable connection between the mounting base 2 and the rotating shaft 600 facilitates the installation and removal of the camera 1.

[0045] For example, the mounting base 2 is connected to the rotating shaft 600 by a number of bolts.

[0046] The drive mechanism 500 in this embodiment includes a motor 510 and a bearing housing 520. The motor 510 is fixed on the outside of a side plate 420 of the hanger 400 along the third direction. A bearing housing 520 is installed on the inner side of each of the two side plates 420. One end of the rotating shaft 600 along the third direction passes through a bearing housing 520 and a side plate 420 and is connected to the output shaft of the motor 510. The other end is connected to another bearing housing 520.

[0047] The drive mechanism 500 also includes an encoder 530 and a coupling (not shown in the figure). The encoder 530 and the motor 510 are respectively mounted on the outside of one of the side plates 420. The end of the rotating shaft 600 away from the motor 510 passes through the bearing housing 520 and the side plate 420 and is connected to the encoder 530 through the coupling. The encoder 530 detects the rotation angle of the rotating shaft 600 and feeds this rotation angle back to the controller. The controller controls the rotation of the rotating shaft 600 to adjust the angle of the camera 1.

[0048] Optionally, the drive mechanism 500 also includes a mounting bracket 540, which is fixed to the side plate 420, and the motor 510 is mounted on the mounting bracket 540.

[0049] like Figure 5 As shown, the maritime inspection VTOL fixed-wing UAV also includes two shock-absorbing mechanisms 700. One shock-absorbing mechanism 700 is installed on the outer side of each of the two side plates 420, with a portion of the shock-absorbing mechanism 700 protruding from the bottom surface of the side plate 420. In this embodiment, by providing a shock-absorbing mechanism 700 on the outer side of each side plate 420 and making the portion of the shock-absorbing mechanism 700 protrude from the bottom surface of the side plate 420, when the maritime inspection VTOL fixed-wing UAV lands, the shock-absorbing mechanism 700 contacts the ground, thus buffering the vibrations generated during the landing of the maritime inspection VTOL fixed-wing UAV.

[0050] For example, the shock absorption mechanism 700 includes a mounting box 710, a shock absorption block 720, and a fixing block 730. The mounting box 710 is fixed to the outside of the side plate 420. The mounting box 710 has a T-shaped stepped hole through it along the second direction. The shock absorption block 720 has a T-shaped structure and passes through the T-shaped stepped hole. The fixing block 730 is located in the T-shaped stepped hole and abuts against the top surface of the shock absorption block 720. The fixing block 730 is fixedly connected to the mounting box 710. The bottom surface of the shock absorption block 720 protrudes from the bottom surfaces of the mounting box 710 and the side plate 420.

[0051] In this embodiment, by providing a T-shaped stepped hole within the mounting box 710 and designing the shock absorber 720 as a T-shaped structure, the shock absorber 720 can be snapped into the T-shaped stepped hole and partially extend through it to protrude beyond the mounting box 710. A fixing block 730 is disposed within the T-shaped stepped hole and positioned above the shock absorber 720. After the shock absorber 720 is fixed to the mounting box 710 using screws or other fasteners, stable installation of the shock absorber 720 can be achieved. Specifically, the fixing block 730 has a T-shaped structure, which is inserted into the T-shaped stepped hole and contacts the upper surface of the mounting box 710, facilitating fixation with screws or other fasteners.

[0052] In this embodiment, the installation process of camera 1 is as follows: First, slide the T-shaped snap-fit ​​protrusion 12 at the bottom of camera 1 into the T-shaped snap-fit ​​groove 221 on the mounting plate 22. Then, install two abutment pins 4 for initial positioning. Next, snap-fit ​​the upper limit frame 3 and push the upper limit frame 3 to the rear so that the rear end face of the pull plate 6 can abut against the front end face of the connecting column 5. Finally, install the fixing pin 7 to achieve quick installation of camera 1. When disassembling camera 1, remove the two fixing pins 7 to remove the upper limit frame 3, and then remove the two abutment pins 4 to slide camera 1 out for replacement.

[0053] The shock absorber 720 is made of rubber. In other embodiments, the shock absorber mechanism 700 can also be designed as a conventional shock absorber spring structure, which will not be described in detail here.

[0054] This application provides a hanger 400 on the drone body 200. One side plate 420 of the hanger 400 is equipped with a drive mechanism 500, and the other side plate 420 is equipped with an encoder 530. The encoder 530 detects the rotation angle and provides data feedback, thereby allowing the working angle of the camera 1 to be adjusted in cooperation with the drive mechanism 500. At the same time, a T-shaped slot 221 is provided on the mounting plate 22 of the camera mounting mechanism 100, which cooperates with the T-shaped snap-fit ​​protrusion 12 on the bottom of the camera 1 housing to achieve quick installation and positioning. Furthermore, by setting a structure of connecting column 5, limit bracket 3, pull plate 6 and fixing pin 7, the stability can be further improved by limiting the position. In addition, the user can disassemble and install the camera 1 without the need for special tools, which solves the problem of inconvenient disassembly and assembly of the camera 1.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them.
