Description

Technical Field

[0001] The present application relates to the technical field of inspection drones, and in particular to a fixed-wing drone camera fixing device and a drone. Background Art

[0002] Transmission line inspection refers to the inspection of transmission lines, the purpose of which is to understand the operating status of transmission lines and promptly discover faults in transmission lines. Substations or high-voltage power towers are usually installed outdoors, which makes it difficult to inspect their transmission lines. Using drones for inspection can reduce the difficulty of inspection.

[0003] However, when the existing power transmission line inspection drones are in use, when the drone needs to land, the drone's support frame will be affected by the downward gravity and the downward impact force during the descent process, and the end of the support frame is prone to friction and collision with the ground, which may seriously damage the internal components of the drone or cause them to loosen, which is not conducive to improving the efficiency of the drone. When the airborne camera is installed on the drone, it is generally limited by fixing bolts, and it is inconvenient for the operator to adjust its placement angle during use. When the airborne camera needs to be inspected and repaired, it must be removed from the equipment, which is inconvenient to operate. Summary of the invention

[0004] In view of this, it is necessary to provide a fixed-wing UAV camera fixing device and a UAV to solve the problem in the prior art that the UAV body and internal components are damaged when the support rod collides with the ground during landing, while facilitating the adjustment of the installation angle of the onboard camera, so that the onboard camera can also be inspected while being rotated.

The clamping block 207 is slidably connected to the mounting block 204. A rotating wheel 205 is rotatably connected to the clamping block 207.

[0006] Furthermore, the two groups of support rods 202 are arranged in an inclined manner, and the top of the mounting block 204 is arranged in an arc structure.

[0007] Furthermore, the mounting mechanism 7 includes a mounting frame 701 and a gasket 702 . Two mounting frames 701 are symmetrically fixedly connected to the base 201 . The gasket 702 is bonded to the top of the mounting frame 701 . The mounting frame 701 is provided with a mounting hole 703 .

[0008] Furthermore, the gasket 702 contacts the bottom end of the drone body 1, and the mounting frame 701 is in an L-shaped structure.

[0009] Furthermore, the adjustment mechanism 5 includes a fixed plate 501 and a worm 502. The fixed plate 501 is fixedly installed on the bottom end of the base 201. The fixed plate 501 is rotatably connected to the worm 502. The worm 502 is meshed with a worm wheel 504. The worm wheel 504 is fixedly installed with a connecting shaft 503.

A clamp plate 602 is fixedly installed on the slider 604, and a rubber pad 603 is bonded to the clamp plate 602. Two sliding grooves 605 are symmetrically provided on the fixed frame 3.

By rotating the adjustment mechanism, the fixing frame can be driven to rotate, so as to facilitate the adjustment of the placement angle of the airborne camera during the installation process, so that the airborne camera can also be inspected while being rotated.

[0026] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0027] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the fixed-wing drone camera fixing device according to the first embodiment of the present invention comprises a mounting mechanism 7 suitable for fixing and connecting the drone body 1; a supporting mechanism 2 is fixed on the mounting mechanism 7; an adjusting mechanism 5 is installed on the supporting mechanism 2; a fixing frame 3 is rotatably mounted on the adjusting mechanism 5; a clamping mechanism 6 is slidably mounted on the fixing frame 3; an airborne camera 4 is mounted between two clamping mechanisms 6; Specifically, Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the support mechanism 2 includes a base 201 and a support rod 202, the bottom end of the drone body 1 contacts the base 201, two groups of support rods 202 are fixedly installed on the base 201, a connecting rod 203 is fixedly installed between two adjacent support rods 202, both ends of the connecting rod 203 are fixedly connected with mounting blocks 204, a telescopic spring 206 is fixedly installed on the mounting block 204, a clamping block 207 is fixedly connected to the telescopic spring 206, a rotating wheel 205 is rotatably connected to the clamping block 207, the two groups of support rods 202 are inclined, the top end of the mounting block 204 is arranged in an arc structure, the cross-sectional height of the mounting block 204 is greater than the cross-sectional diameter of the connecting rod 203, and the clamping block 207 is slidably connected to the mounting block 204.

[0028] Specifically, Figure 1 and Figure 3As shown, the mounting mechanism 7 includes a mounting frame 701 and a gasket 702. Two mounting frames 701 are symmetrically fixedly connected to the base 201. The top of the mounting frame 701 is bonded with a gasket 702. The mounting frame 701 is provided with a mounting hole 703. The gasket 702 contacts the bottom end of the drone body 1. The mounting frame 701 is arranged in an L-shaped structure. The supporting mechanism 2 can be fixed to the bottom end of the drone body 1 through the mounting mechanism 7. When the drone body 1 lands, the downward gravity and the downward impact force of the drone body 1 can be buffered by the supporting mechanism 2, which is beneficial to prevent the internal components of the drone body 1 from being damaged or loosened. That is, the operator can pass the fixing bolts through the mounting holes 703 provided on the mounting frame 701, and use a tool to rotate the fixing bolts to fix the mounting frame 701 to the bottom end of the drone body 1. The mounting frame 701 is arranged in an L-shaped structure, which is convenient for the operator to disassemble and assemble the mounting frame 701; the gasket 702 bonded on the mounting frame 701 is in contact with the drone body. 1, the base 201 fixed on the mounting frame 701 can be installed on the drone body 1; when the drone body 1 lands, the base 201 moves with the drone body 1 to drive the support rods 202 fixed on both sides to land. Since the two adjacent support rods 202 are connected by the connecting rod 203, when the connecting rod 203 moves toward the ground, the mounting blocks 204 fixed at both ends of the connecting rod 203 can move with it. There is a card block 207 sliding inside the mounting block 204. When the card block 207 is set When the rotating wheel 205 contacts the ground, the rotating wheel 205 can drive the block 207 to slide towards the top of the mounting block 204 under the action of the impact force. When the block 207 slides, it squeezes the telescopic spring 206 fixed in the mounting block 204. When the telescopic spring 206 is in a compressed state, it can buffer the downward gravity and downward impact force on the support rod 202, thereby preventing the internal components of the drone body 1 from being damaged or loosened when the support rod 202 collides with the ground.

[0029] Specifically, Figure 1 , Figure 4 , Figure 7 and Figure 8As shown, the adjustment mechanism 5 includes a fixing plate 501 and a worm 502. The fixing plate 501 is fixedly installed at the bottom end of the base 201. The fixing plate 501 is rotatably connected to the worm 502. The worm 502 is meshed with a worm wheel 504. The worm wheel 504 is fixedly installed with a connecting shaft 503. The connecting shaft 503 is fixedly connected to a fixing frame 3. The connecting shaft 503 is rotatably connected to the fixing plate 501. The fixing frame 3 is rotatably mounted on the fixing plate 501. The adjustment mechanism 5 is rotated by using a tool to drive the fixing frame 3 to rotate, thereby facilitating the adjustment of the placement angle of the airborne camera 4 during the installation process, so that the camera 4 can also be rotated. When the airborne camera 4 is repaired, that is, when the airborne camera 4 is installed, the operator can use a tool to rotate the worm 502. When the worm 502 rotates in the fixed plate 501 installed at the bottom of the base 201, the worm wheel 504 meshing on the worm 502 can be rotated in the fixed plate 501 together with the worm 502. When the worm wheel 504 drives the connecting shaft 503 to rotate, the fixing frame 3 installed on the connecting shaft 503 can be rotated in the fixing plate 501. The rotation of the fixing frame 3 is convenient for driving the airborne camera 4 to rotate, and then it is convenient to adjust the installation angle of the airborne camera 4 when installing it, so that the airborne camera 4 can be repaired when it is rotated.

[0030] In addition, high-precision transmission can be achieved through the meshing of the worm 502 and the worm wheel 504. For every rotation of the worm, the worm wheel only rotates a small angle, which allows the operator to fine-tune the rotation angle of the worm wheel by rotating the worm. The connecting shaft 503 on the worm wheel 504 is fixedly connected to the fixed frame 3, so that when the worm wheel rotates, the connecting shaft 503 will also rotate, thereby driving the fixed frame 3 to rotate. Angle adjustment during installation: When installing the airborne camera, the operator can adjust the angle of the fixed frame 3 by rotating the worm 502, thereby ensuring that the viewing angle of the airborne camera meets the inspection requirements. The cooperation between the worm and the worm wheel also has a certain self-locking function, that is, when the worm wheel stops rotating, the worm will not rotate in the opposite direction due to the action of external force, which ensures the stability and safety of the airborne camera during use.

[0031] Specifically, Figure 1 , Figure 2 , Figure 4 , Figure 7 and Fig. 9As shown, the clamping mechanism 6 includes a rotating rod 601 and a slider 604, the rotating rod 601 is rotatably connected to the fixing frame 3, the slider 604 is threadedly connected to the rotating rod 601, a clamping plate 602 is fixedly installed on the slider 604, a rubber pad 603 is bonded to the clamping plate 602, two sliding grooves 605 are symmetrically arranged on the fixing frame 3, the slider 604 slides on the sliding groove 605, the cross-sectional width of the sliding groove 605 is equal to the cross-sectional width of the slider 604, the airborne camera 4 is clamped and installed between the two clamping plates 602, the rubber pad 603 is in contact with the side wall of the airborne camera 4, and the clamping mechanism 6 is rotated by using a tool, so that the two clamping mechanisms 6 can clamp and fix the airborne camera 4 when sliding toward each other in the fixing frame 3, thereby facilitating the disassembly and assembly of the airborne camera 4, that is: the operator Use a tool to rotate the rotating rod 601. When the rotating rod 601 rotates in the fixing frame 3, the rotating rod 601 can drive the slider 604 threadedly connected to it to slide in the fixing frame 3. When the slider 604 slides in the slide groove 605 provided in the fixing frame 3, the clamping plate 602 fixed at the end of the slider 604 can slide with it. The clamping plate 602 is fixed to the side wall of the slider 604 away from the rotating rod 601. When the two clamping plates 602 slide toward each other in the fixing frame 3, the two clamping plates 602 can clamp the side wall of the airborne camera 4, and rubber pads 603 are bonded to the clamping plates 602. When the rubber pads 603 conflict with the side wall of the airborne camera 4, the friction between the clamping plates 602 and the airborne camera 4 can be increased, so that the fixing frame 3 can also protect the airborne camera 4 when the operator is convenient to quickly disassemble and assemble it.

[0032] The drone according to the second embodiment of the present invention comprises a drone body 1 and the fixed-wing drone camera fixing device described in the above embodiment, wherein the fixed-wing drone camera fixing device is fixedly connected to the drone body 1.

[0033] When the present invention is in use, first, the operator can pass the fixing bolt through the mounting hole 703 provided on the mounting frame 701, and use a tool to rotate the fixing bolt, so that the mounting frame 701 can be fixed to the bottom end of the drone body 1, and the mounting frame 701 is arranged in an L-shaped structure, which is convenient for the operator to disassemble and assemble the mounting frame 701; when the gasket 702 bonded on the mounting frame 701 contacts the bottom end of the drone body 1, the base 201 fixed on the mounting frame 701 can be installed on the drone body 1; when the drone body 1 lands, the base 201 moves with the drone body 1 to drive the support rods 202 fixed on both sides to land, and since the two adjacent support rods 202 are connected by the connecting rod 203, the connecting rod 203 is connected to the supporting rod 202. When the connecting rod 203 moves toward the ground, the mounting blocks 204 fixed at both ends of the connecting rod 203 can be displaced together with it. A card block 207 slides inside the mounting block 204. When the rotating wheel 205 arranged in the card block 207 contacts the ground, the rotating wheel 205 can drive the card block 207 to slide toward the top of the mounting block 204 under the action of the impact force. When the card block 207 slides, it squeezes the telescopic spring 206 fixed in the mounting block 204. When the telescopic spring 206 is in a compressed state, it can buffer the downward gravity and downward impact force exerted on the support rod 202, thereby preventing the internal components of the drone body 1 from being damaged or loosened when the support rod 202 collides with the ground.

[0034] The operator uses a tool to rotate the rotating rod 601. When the rotating rod 601 rotates in the fixing frame 3, the rotating rod 601 can drive the slider 604 threadedly connected to it to slide in the fixing frame 3. When the slider 604 slides in the slide groove 605 provided in the fixing frame 3, the clamping plate 602 fixed at the end of the slider 604 can slide with it. The clamping plate 602 is fixed to the side wall of the slider 604 away from the rotating rod 601. When the two clamping plates 602 slide toward each other in the fixing frame 3, the two clamping plates 602 can clamp the side wall of the airborne camera 4, and rubber pads 603 are bonded to the clamping plates 602. When the rubber pads 603 conflict with the side wall of the airborne camera 4, the friction between the clamping plates 602 and the airborne camera 4 can be increased, thereby facilitating the operator to quickly disassemble and assemble the airborne camera 4.

[0035] When the airborne camera 4 is installed, the operator can use a tool to rotate the worm 502. When the worm 502 rotates in the fixed plate 501 installed at the bottom of the base 201, the worm wheel 504 meshing on the worm 502 can rotate in the fixed plate 501 together with the worm 502. When the worm wheel 504 drives the connecting shaft 503 to rotate, the fixing frame 3 installed on the connecting shaft 503 can rotate in the fixing plate 501. The rotation of the fixing frame 3 is convenient for driving the airborne camera 4 to rotate, and then it is convenient to adjust the installation angle of the airborne camera 4 when installing it, so that the airborne camera 4 can also be inspected when it is rotated.
