Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to an inspection UAV. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control device and its own program control device, or operated completely or intermittently autonomously by an onboard computer. Drones can be divided into military and civilian use according to their application areas. In the military sector, drones are divided into reconnaissance aircraft and target aircraft, while civilian use is the real demand for drones.

[0003] During the inspection process, inspection personnel often need to use drones to complete the inspection tasks to improve the inspection effect of the inspection personnel. However, the camera components of existing inspection drones are usually fixed by multiple bolts, which is not convenient for quick disassembly and assembly, reducing the maintenance speed of the camera. In addition, existing inspection drones do not have protective components for the camera components. During the landing process of the inspection drone, the camera components are easily damaged. Utility Model Content

[0004] In order to solve the problems in the background technology, the purpose of the present invention is to provide an inspection drone.

[0005] The utility model provides the following technical solutions: a patrol drone, comprising a drone body, a shooting mechanism for mounting a camera arranged on the drone body, and a protective mechanism for protecting the camera arranged on the shooting mechanism; the shooting mechanism comprises a bracket arranged on the drone body, a mounting frame rotatably connected to the bracket, the camera mounted in the mounting frame, a driving member for driving the mounting frame to rotate, and a limiting assembly arranged in the mounting frame for limiting the camera; the limiting assembly comprises a slide slidably connected in the mounting frame, a driving member for driving the slide to slide, and a wedge block arranged at the front end of the slide, the wedge block being inclined on the side close to the camera.

[0006] Furthermore, the drone body includes a fuselage, a plurality of support frames arranged around the fuselage, and a buffer pad arranged at the bottom end of the support frame.

[0007] Furthermore, the driving member is a motor, the output shaft of the motor is fixedly connected to the installation frame, and there is damping between the connection between the installation frame and the bracket.

[0008] Furthermore, the driving component includes a motor arranged on the drone body, a worm arranged on the output shaft of the motor, and a turbine arranged on the mounting frame. The worm is engaged with the turbine, and the motor is started through the worm and the turbine to rotate the mounting frame.

[0009] Furthermore, the driving component is a screw, which is threadedly connected to the installation frame, one end of the screw is rotatably connected to the slide, and the other end passes through the side wall of the installation frame and is exposed to the outside.

[0010] Furthermore, the wedge block is slidably connected to the slide plate, and a first spring is provided between the wedge block and the slide plate.

[0011] Furthermore, the protective mechanism includes a sliding sleeve arranged at the lower part of the mounting frame, an inner groove opened inside the sliding sleeve, a telescopic block to which the sliding sleeve is slidingly connected through the inner groove, and a plurality of second springs arranged between the telescopic block and the sliding sleeve, and the second springs are located at the inner groove.

[0012] The beneficial effect of the utility model is that by rotating the screw rod, the screw rod drives the slide plate to move in the direction away from the camera. At this time, the slide plate will no longer press the camera, and the movement of the slide plate will drive the wedge block to move, and the wedge block will no longer block the front end of the camera, so that the camera can be taken out from the opening on the front side of the mounting frame. When the camera needs to be installed back, the operator can place the camera inside the mounting frame, and then rotate the screw rod in the opposite direction. The screw rod drives the slide plate to move in the direction close to the camera and press the slide plate against the camera, thereby limiting the camera. When the slide plate moves in the direction close to the camera, it will drive the wedge block to move, thereby moving the wedge block to the side of the front of the camera, thereby blocking the camera, further limiting the camera and preventing the camera from falling out of the front of the mounting frame, thereby achieving the effect of facilitating the disassembly and assembly of the camera. In addition, through the provision of the protective mechanism, when the drone falls, if there is a stone under the camera, the stone will contact the telescopic block, and the second spring will buffer the contact force between the telescopic block and the stone, avoiding transmission to the camera and causing damage to the camera, thereby achieving the effect of protecting the camera.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] An inspection drone, such as Figure 1-Figure 3As shown, it includes a drone body, a shooting mechanism 4 for mounting a camera 45 provided on the drone body, and a protective mechanism 5 for protecting the camera 45 provided on the shooting mechanism 4; the shooting mechanism 4 includes a bracket 42 provided on the drone body, a mounting frame 43 rotatably connected to the bracket 42, the camera 45 is mounted in the mounting frame 43, and a driving member 41 for driving the mounting frame 43 to rotate, and a limiting assembly 44 provided in the mounting frame 43 for limiting the camera 45; the limiting assembly 44 includes a slide plate 442 slidably connected in the mounting frame 43, a driving member for driving the slide plate 442 to slide, and a wedge block 444 provided at the front end of the slide plate 442, the wedge block 444 having an inclined surface 447 on the side close to the camera 45.

[0023] Among them, the drone body is equipped with a wireless communication module, a power module, a control module, etc. The wireless communication module is used to receive ground control signals and send electrical signals to the control module according to the signals, so that the control module controls the flight direction and speed of the drone body and controls the angle of rotation of the mounting frame 43 driven by the driving member 41. The power module is used to provide power. In addition, a first slide groove 441 is provided on the mounting frame 43, and the mounting frame 43 is slidingly connected to the slide plate 442 through the first slide groove 441. The driving component is a screw 443 in this embodiment, and can be an electric push rod in other embodiments. The screw 443 is threadedly connected to the mounting frame 43, and one end of the screw 443 is rotatably connected to the slide plate 442, and the other end passes through the side wall of the mounting frame 43 and is exposed to the outside.

[0024] Specifically, when the operator needs to remove the camera 45 in the mounting frame 43 for maintenance, the operator only needs to rotate the screw 443, which drives the slide plate 442 to move in the direction away from the camera 45. At this time, the slide plate 442 will no longer press the camera 45, and the movement of the slide plate 442 will drive the wedge block 444 to move, and the wedge block 444 will no longer block the front end of the camera 45, so that the camera 45 can be taken out from the opening on the front side of the mounting frame 43. When the camera 45 needs to be installed back, the operator can place the camera 45 into the inner side of the mounting frame 43 and make the rear end of the camera 45 contact the inner rear side of the mounting frame 43. At this time, the operator can rotate the screw 443 in the opposite direction, which drives the slide plate 442 to move in the direction close to the camera 45 and makes the slide plate 442 press the camera 45, thereby limiting the camera 45, and when the slide plate 442 moves close to the camera 45 When the camera 45 moves in the opposite direction, the wedge block 444 will be driven to move. When the camera 45 protrudes slightly, the inclined surface 447 of the wedge block 444 will squeeze the camera 45, causing the camera 45 to move deeper into the inside of the mounting frame 43, thereby moving the wedge block 444 to the side of the front of the camera 45, thereby blocking the camera 45, further limiting the position of the camera 45, and preventing the camera 45 from falling out of the front of the mounting frame 43; in addition, after the camera 45 is installed, during the operation of the inspection drone, when the camera 45 needs to adjust the angle to take pictures, the operator operates the ground controller, the ground controller sends a signal, which is received by the wireless communication module, and the wireless communication module sends an electrical signal to the control module based on the signal. The control module controls the drive member 41 to start, and the drive member 41 will drive the mounting frame 43 to rotate to the corresponding angle. The mounting frame 43 rotates to the corresponding angle, driving the camera 45 therein to rotate to the corresponding angle.

[0025] like Figure 1 As shown, the drone body includes a fuselage 1, a plurality of support frames 2 arranged around the fuselage 1, and a buffer pad 3 arranged at the bottom end of the support frame 2.

[0026] It can be understood that when the drone body falls, the support frame 2 holds up the fuselage 1 and the buffer pad 3 buffers the force of falling, thereby protecting the electronic components in the fuselage 1 and also protecting the camera 45.

[0027] like Figure 2 As shown, in this embodiment, the driving member 41 is a motor, the output shaft of the motor is fixedly connected to the installation frame 43, and there is damping between the connection between the installation frame 43 and the bracket 42.

[0028] It can be understood that the control module controls the motor to start, and the motor starts its output shaft to drive the mounting frame 43 to rotate, thereby rotating the camera 45 to a corresponding angle. Due to the damping between the mounting frame 43 and the bracket 42, the mounting frame 43 can be prevented from rotating on the bracket 42 during the flight of the drone, thereby affecting the shooting;

[0029] In other embodiments, the driving member 41 includes a motor provided on the drone body, a worm provided on the output shaft of the motor, and a turbine provided on the mounting frame 43, the worm being engaged with the turbine, and the motor being started through the worm and the turbine transmission, thereby rotating the mounting frame 43; it can be understood that the control module controls the start-up of the motor, and the output shaft of the motor starts to drive the worm to rotate, the rotation of the worm drives the turbine to rotate, and the rotation of the turbine drives the mounting frame 43 to rotate, thereby rotating the camera 45 to the corresponding angle for shooting, and through the cooperation of the worm and the turbine, the mounting frame 43 will not rotate autonomously during the flight of the drone, thereby ensuring that the shooting process is not affected.

[0030] like Figure 4 As shown, the wedge block 444 is slidably connected to the slide 442, and a first spring 446 is provided between the wedge block 444 and the slide 442; a second sliding groove 445 is provided on the wedge block 444, and the wedge block 444 is slidably connected to the slide 442 through the second sliding groove 445.

[0031] It is understandable that when the operator places the camera 45 into the mounting frame 43, human error may occur, causing the camera 45 to be exposed too much to the outside. When the operator rotates the screw 443 to drive the slide 442 and the wedge block 444 to move, in order to prevent the wedge block 444 from damaging the camera 45, when the wedge block 444 moves toward the direction close to the camera 45, since the camera 45 is exposed too much to the outside, the wedge block 444 will contact the plane of the camera 45. If the operator is still driving the slide 442 to move toward the direction close to the camera 45, the wedge block 444 will slide on the slide 442, and the first spring 446 will be compressed, thereby avoiding the wedge block 444 from rigidly contacting the camera 45 and causing damage to the camera 45.

[0032] like Figure 5 As shown, the protective mechanism 5 includes a sliding sleeve 51 arranged at the lower part of the mounting frame 43, an inner groove 53 opened inside the sliding sleeve 51, a telescopic block 52 to which the sliding sleeve 51 is slidingly connected through the inner groove 53, and a plurality of second springs 54 arranged between the telescopic block 52 and the sliding sleeve 51, and the second springs 54 are located at the inner groove 53.

[0033] It can be understood that during the landing of the drone, due to the complex road conditions, there may be protruding stones on the ground below the camera 45. In order to protect the camera 45, a protective mechanism 5 is set up. Specifically, when the drone falls, if there are stones under the camera 45, the stones will contact the telescopic block 52, and the second spring 54 will buffer the contact force between the telescopic block 52 and the stone to avoid transmission to the camera 45 and causing damage to the camera 45, thereby protecting the camera 45.

[0034] In summary, by rotating the screw rod 443, the screw rod 443 drives the slide plate 442 to move in the direction away from the camera 45. At this time, the slide plate 442 will no longer press the camera 45, and the movement of the slide plate 442 will drive the wedge block 444 to move. The wedge block 444 no longer blocks the front end of the camera 45, so that the camera 45 can be taken out from the opening on the front side of the installation frame 43. When the camera 45 needs to be installed back, the operator can place the camera 45 on the inner side of the installation frame 43, and then rotate the screw rod 443 in the opposite direction. The screw 443 drives the slide plate 442 to move in the direction close to the camera 45, and makes the slide plate 442 press the camera 45, thereby limiting the position of the camera 45, and When the slide plate 442 moves toward the direction approaching the camera 45, it will drive the wedge block 444 to move, thereby moving the wedge block 444 to the side of the front of the camera 45, thereby blocking the camera 45, and further limiting the camera 45 to prevent the camera 45 from falling out from the front of the mounting frame 43, thereby achieving the effect of facilitating the disassembly and assembly of the camera 45. In addition, through the setting of the protective mechanism 5, when the drone falls, if there is a stone under the camera 45, the stone will contact the telescopic block 52, and the second spring 54 will buffer the contact force between the telescopic block 52 and the stone, avoiding transmission to the camera 45 and causing damage to the camera 45, thereby achieving the effect of protecting the camera 45.
