[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 and Figure 2, an embodiment provided by the present utility model: a grasping device for an unmanned aerial vehicle for power transmission line inspection, including an unmanned aerial vehicle body 1, which provides flight ability and position control and is used to observe sundries on the wire. A mounting block 2 is fixedly connected to the bottom end of the unmanned aerial vehicle body 1 for mounting the mounting shell 3. The inner wall of the bottom end of the mounting block 2 is provided with a mounting shell 3 for providing stable support for the grasping component. A driving motor 4 is fixedly connected to the inner wall of the mounting shell 3 to provide power and drive the grasping component to move. The inner wall of the bottom end of the mounting shell 3 is provided with a grasping component. The grasping component includes a worm 51, which drives the worm gear 52 to rotate through meshing with the worm gear 52 to realize the transfer of force direction. The bottom end of the worm 51 is fixedly connected to the bottom end of the output shaft of the driving motor 4, and the bottom end of the worm 51 is rotatably connected to the inner wall of the mounting shell 3 to improve the stability of the rotation of the worm 51. The front end of the worm 51 is meshed with a worm gear 52 for driving a bidirectional threaded rod 53 to rotate. The inner wall of the worm gear 52 is fixedly connected with a bidirectional threaded rod 53. The bidirectional threaded rod 53 is used to drive the first clamping rod 54 and the second clamping rod 55 to move in opposite directions, so as to realize the clamping and releasing of sundries. The middle part of the bidirectional threaded rod 53 is rotatably connected to the inner wall of the mounting shell 3 near both sides of the worm gear 52 to improve the stability of the rotation of the bidirectional threaded rod 53. The first clamping rod 54 is threadedly connected to the outer wall of the right side of the bidirectional threaded rod 53, and the second clamping rod 55 is threadedly connected to the outer wall of the left side of the bidirectional threaded rod 53. The first clamping rod 54 and the second clamping rod 55 are used in cooperation to clamp sundries, so as to remove the sundries from the wire and keep the wire clean.

[0032] Refer to Figure 2 - Figure 4 , the front end of the second clamping rod 55 is slidably connected to the inner wall of the mounting shell 3, the rear side of the first clamping rod 54 slides on the inner wall of the mounting shell 3, and the rear side of the second clamping rod 55 is slidably connected to the front end of the first clamping rod 54, which can improve the stability of the movement of the first clamping rod 54 and the second clamping rod 55. A fixing needle 56 is fixedly connected to the left side of the bottom end of the second clamping rod 55 for fixing sundries, so as to improve the removal efficiency. A sliding rod 57 is slidably connected to the inner wall of the left side of the bottom end of the second clamping rod 55. There are multiple groups of sliding rods 57. When the sliding rod 57 slides, it squeezes the compression spring 58, so that the two pressing plates 59 can move to both sides. The sliding rod 57 and the second clamping rod 55 are elastically connected through the compression spring 58. Through the elastic force of multiple groups of compression springs 58, the two pressing plates 59 can be reset, so as to clean the sundries fixed on the fixing needle 56. The left side of the sliding rod 57 is fixedly connected with a pressing plate 59. By squeezing the sundries, the fixing needle 56 can be exposed from the through hole 510, so as to fix the sundries. A through hole 510 is formed through the left side of the pressing plate 59. There are multiple groups of fixing needles 56 and through holes 510, and the fixing needles 56 and the through holes 510 are evenly distributed. The fixing needle 56 can slide on the inner wall of the through hole 510 to fix the sundries, so as to improve the cleaning efficiency of the sundries. The pressing plate 59 is U-shaped, which can wrap the inner side and both sides of the first clamping rod 54 and the second clamping rod 55 to prevent the fixing needle 56 from hurting the operator.

[0033] Refer to Figure 1 and Figure 5 On the inner wall of the top end of the installation shell 3, a disassembly component is provided. The disassembly component includes a push rod 61. The outer wall on the right side of the push rod 61 is slidably connected to the inner wall of the installation shell 3. The push rod 61 is used in cooperation with the limiting groove 63 to limit the installation shell 3, so as to quickly disassemble and install the installation shell 3. The push rod 61 and the installation shell 3 are elastically connected by a return spring 62. Through the elastic force of the return spring 62, the stability of the push rod 61 during the operation of the device is improved. A limiting groove 63 is provided near the top end of the installation block 2 for limiting the installation shell 3. The top end of the push rod 61 slides on the inner wall of the limiting groove 63. Two sets of push rods 61, return springs 62 and limiting grooves 63 are provided. The two sets of push rods 61, return springs 62 and limiting grooves 63 are symmetrically arranged with the center line of the installation shell 3 as the axis of symmetry, improving the stability of the installation shell 3 during installation.

[0034] Working principle: When in use, when it is necessary to clean the sundries on the wire, align the clamping rod 54 with the clamping rod 55 to the sundries. At this time, start the driving motor 4. The output shaft of the driving motor 4 drives the worm 51 to rotate on the inner wall of the installation shell 3. The worm 51 drives the worm wheel 52 to rotate by meshing with the worm wheel 52. While the worm wheel 52 is rotating, it drives the bidirectional threaded rod 53 to rotate on the inner wall of the installation shell 3. The bidirectional threaded rod 53 drives the clamping rod 54 and the clamping rod 55 to move towards each other through the threads on the outer wall, so that the clamping rod 54 and the clamping rod 55 clamp the sundries.

[0035] During the clamping process, due to the extrusion force on the sundries, the two sets of pressing plates 59 drive the sliding rod 57 to slide on the inner walls of the clamping rod 54 and the clamping rod 55, and squeeze the compression spring 58, so that the two sets of pressing plates 59 move towards the outside of the clamping rod 54 and the clamping rod 55. When moving, the fixing pins 56 slide out of the through holes 510 to ensure stable and effective fixing of the sundries. At this time, the sundries are removed from the wire by the movement of the UAV body 1.

[0036] After removal, by rotating the bidirectional threaded rod 53 in the reverse direction, the clamping rod 54 and the clamping rod 55 are driven to move in the reverse direction to release the limit on the sundries. At this time, the elastic force of the compression spring 58 drives the pressing plate 59 to move to clean the sundries fixed on the fixing pins 56, so that the sundries can fall or be centrally collected.

[0037] When it is necessary to maintain the device, by pushing the two sets of push rods 61, the push rods 61 slide on the inner wall of the installation shell 3 to squeeze the return spring 62. During the movement of the push rods 61, they slide out of the inner wall of the limiting groove 63, so as to release the limit on the installation shell 3. At this time, the installation shell 3 can be removed for maintenance.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
