Description

Technical Field

[0001] The present invention relates to the technical field of UAV shooting, and particularly to a UAV shooting device for infrared imaging of insulator deterioration. Background Art

[0002] Insulators, commonly known as porcelain bottles, are insulators used to support conductors. Insulators can ensure sufficient insulation between conductors and cross arms or poles and towers. They should be able to withstand the vertical load and horizontal tension of the conductors during operation, and they are also exposed to sunlight, rain, climate change, and chemical corrosion. Therefore, insulators need to have good electrical performance and sufficient mechanical strength. The quality of insulators is very important for the safe operation of the line, so it is necessary to regularly check for insulator deterioration. Currently, the commonly used method is to shoot through a UAV and use infrared imaging to check for insulator deterioration.

[0003] Currently, most installations of UAV shooting devices are achieved by installing a pod at the lower end of the UAV and fixing the shooting device to the pod. The connection between the pod and the shooting device is mainly through screw installation. In this way, during and after the shooting work, it is impossible to quickly install and disassemble the shooting device and the UAV. After the UAV shooting device is installed, it cannot protect its own lens during operation, and sundries floating in the air will cause certain damage to the lens, affecting the service life of the shooting device.

[0004] The information disclosed in this background art section is only intended to deepen the understanding of the overall background art of the present disclosure, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0041] As Figures 1 to 11 shown, the UAV shooting device for insulator deterioration infrared imaging includes: an inner movable plate 1, an outer sheath 2, a pod 3, a locking mechanism and an unlocking mechanism.

[0042] As Figure 3 and 6 shown, the inner movable plate 1 can adopt a circular plate structure. The contour of the inner movable plate 1 is adapted to the inner contour of the outer sheath 2. The inner movable plate 1 is movably connected inside the outer sheath 2. The way of movable connection here can be hinge connection, sliding connection and other ways, as long as it is ensured that the inner movable plate 1 can move up and down relative to the outer sheath 2. A connecting sleeve 4 is arranged at the center of the top surface of the inner movable plate 1. First transverse holes 5 are opened on the opposite side walls of the connecting sleeve 4. A camera 6 and an infrared sensor 7 are fixedly arranged on the bottom surface of the inner movable plate 1;

[0043] The outer sheath 2 is in a cylindrical shape, and a transparent cover 8 is arranged on the outer sheath 2 in the irradiation direction of the camera 6 and the infrared sensor 7;

[0044] The pod 3 includes a first disc 9 and a first ring 10 located at the bottom of the first disc 9. The inner diameter of the first ring 10 is greater than or equal to the outer diameter of the outer sheath 2. A socket 11 is arranged at the center of the bottom surface of the first disc 9. The outer contour of the socket 11 is adapted to the inner contour of the connecting sleeve 4. Second transverse holes 12 are arranged at the positions of the socket 11 corresponding to the first transverse holes 5;

[0045] The locking mechanism includes a locking sleeve 13 and a driving mechanism for driving the locking sleeve 13 to extend into the second transverse hole 12. The driving mechanism is arranged between the outer sheath 2 and the inner movable plate 1 and moves following the inner movable plate 1. On the one hand, the driving mechanism ensures the movable connection relationship between the outer sheath 2 and the inner movable plate 1. On the other hand, when the inner movable plate 1 rises relative to the outer sheath 2, it can drive the locking sleeve 13 to extend from outside the connecting sleeve 2 into the socket 11, so as to fixedly connect the connecting sleeve 2 and the socket 11, that is, the inner movable plate 1 is fixed in the nacelle 3;

[0046] The unlocking mechanism is used to push the locking sleeve 13 out of the second transverse hole 12. The form and structure of the unlocking mechanism can be various. The technical effect to be achieved is to move the locking sleeve 13 outwards from the socket 11. When the locking sleeve 13 is moved out of the second transverse hole 12, the limit connection of the socket 11 can be released, so as to separate the inner movable plate 1 and the outer sheath 2 from the nacelle 3, and the disassembly process is simple and convenient.

[0047] As Figure 3 and 4 shown, in this embodiment, a specific locking mechanism is disclosed. The locking mechanism further includes a first guide rod 14, a guide rod fixing seat 15, a sliding seat 16, a first connecting rod 17 and a hinge support 18. The first guide rod 14 is arranged on the extension line of the connection line between the two first transverse holes 5. The end of the first guide rod 14 far from the first transverse hole 5 is fixed on the top surface of the inner movable plate 1 through the guide rod fixing seat 15. The sliding seat 16 is slidably connected with the first guide rod 14. One end of the first connecting rod 17 is hinged to the top of the sliding seat 16 and the other end is hinged to the hinge support 18. The hinge support 18 is located at the top end of the inner wall of the outer sheath 2. The locking sleeve 13 is connected to one side of the sliding seat 16 close to the first transverse hole 5 through an elastic component. The setting of the locking mechanism of the present invention can realize the up and down movement of the inner movable plate 1 relative to the outer sheath 2. In specific implementation, the upper end of the outer sheath 2 is inserted into the first ring 10 and its upper end surface is in contact with the bottom surface of the first disc 9. By pushing the camera 6 upwards, the inner movable plate 1 is driven to move upwards. During the upward movement of the inner movable plate 1, under the action of the first connecting rod 17, the sliding seat 16 will be pushed to move in the direction close to the connecting sleeve 4. At the same time, the socket 11 is inserted into the connecting sleeve 4, and then the locking sleeve 13 will contact the socket 11. As the camera 6 moves upwards, when the first transverse hole 5 and the second transverse hole 12 are aligned, under the action of the elastic component, the locking sleeve 13 is inserted into the second transverse hole 12 to fix the positions of the camera 6 and the infrared sensor 7. At this time, the camera 6 and the infrared sensor 7 are also raised to the position of the transparent cover 8 for shooting work.

[0048] As Figure 4As shown, as a specific disclosure of the above embodiment, the elastic component includes a movable plate 19, a movable connecting rod 20, a disc end block 22 and a collar 23. First circular holes for the movable connecting rod 20 to pass through are provided on both sides of the sliding seat 16. Both ends of the movable connecting rod 20 protrude from the first circular holes. The disc end block 22 is connected to the end of the movable connecting rod 20 far from the connecting sleeve 4. A first spring 21 is sleeved on the movable connecting rod 20 between the disc end block 22 and the sliding seat 16. The collar 23 is fixedly connected between the two disc end blocks 22. The collar 23 is sleeved on the first guide rod 14. The locking sleeve 13 is fixed to one side of the movable plate 19 close to the connecting sleeve 4. Both the movable plate 19 and the locking sleeve 13 have through holes for the first guide rod 14 to pass through. During the upward movement of the inner movable plate 1, the first spring 21 elongates. When the first transverse hole 5 and the second transverse hole 12 are aligned, under the action of the first spring 21, the locking sleeve 13 is inserted into the second transverse hole 12, realizing the position fixation of the camera 6 and the infrared sensor 7.

[0049] More specifically, a second spring 24 is sleeved on the first guide rod 14. Both ends of the second spring 24 are respectively connected to the guide rod fixing seat 15 and the sliding seat 16.

[0050] In order to achieve quick unlocking and move the locking sleeve 13 out of the second transverse hole 12, the unlocking mechanism includes a pressing unlocking rod 25, a triangular unlocking block 26 and a limiting convex ring 27. A third transverse hole is further provided in the socket 11 in the direction perpendicular to the connection line of the two second transverse holes 12. One end of the pressing unlocking rod 25 is inserted into the third transverse hole and fixedly connected to the triangular unlocking block 26 located in the socket 11, and the other end extends outwards. Avoidance openings 29 for the pressing unlocking rod 25 to pass through are provided on the side wall of the connecting sleeve 4 and the side wall of the outer sheath 2. The limiting convex ring 27 is arranged on the surface of the pressing unlocking rod 25. A third spring 28 is arranged on the pressing unlocking rod 25 between the limiting convex ring 27 and the third transverse hole. The first circular ring 10 is provided with a pressing hole 30 corresponding to the pressing unlocking rod 25. When the unlocking mechanism is in use, by pushing the pressing unlocking rod 25 inwards, the triangular unlocking block 26 is brought into contact with the locking sleeve 13. When the pressing unlocking rod 25 gradually moves inwards, the triangular unlocking block 26 completely moves the locking sleeve 13 out of the second transverse hole 12, and the connection between the connecting sleeve 4 and the socket 11 can be released.

[0051] In order to increase the contact area between the hand and the pressing unlocking rod 25, a pressing block 31 is further connected to the end of the pressing unlocking rod 25 far from the socket 11. The pressing block 31 can pass through the pressing hole 30, and the transverse movement of the pressing unlocking rod 25 is realized by touching the pressing block 31 with the hand.

[0052] To increase the protection of the camera 6 and the infrared sensor 7 and facilitate dust removal from the surface of the transparent cover 8, an auxiliary protection and dust removal mechanism is further included. The auxiliary protection and dust removal mechanism includes an upward push guard plate 32, two second guide rods 33, and a sponge block 34. Notches 35 are symmetrically formed at the bottom of the outer sheath 2. Each second guide rod 33 is individually located in one of the notches 35 and its top end is fixed to the top surface of the notch 35. The upward push guard plate 32 is provided with through holes for the second guide rods 33 to pass through. The outer diameter of the upward push guard plate 32 is larger than that of the outer sheath 2. The upward push guard plate 32 is also provided with an outer sheath insertion hole 36 for the outer sheath 2 to pass through. A fourth spring 37 is sleeved on the second guide rod 33, and both ends of the fourth spring 37 are fixedly connected to the top surface of the notch 35 and the upward push guard plate 32 respectively. A wiping vertical plate 38 is provided on the upper surface of the upward push guard plate 32 corresponding to the outside of the transparent cover 8. An installation slot 39 is provided at the top end of the wiping vertical plate 38. The sponge block 34 is installed in the installation slot 39. The bottom of the outer sheath 2 is covered by the upward push guard plate 32, thereby increasing the protection of the camera 6 and the infrared sensor 7. By moving the upward push guard plate 32 up and down, the sponge block 34 is used to wipe the surface of the transparent cover 8. The transparent cover 8 does not require additional cleaning. When installing the photographing device, automatic cleaning can be carried out to ensure its cleanliness, and thus ensure the smooth progress of the photographing work.

[0053] In order to blow the dust on the surface of the transparent cover 8, the auxiliary protection and dust removal mechanism further includes a blowing component. The blowing component is arranged on both sides of the transparent cover 8 and is used to blow air towards the transparent cover 8. The blowing component includes two blowing cylinders 40 and two inclined top plates 41. On both sides of the upper end of the wiping vertical plate 38, side protrusions 42 are symmetrically arranged. The two blowing cylinders 40 are respectively fixed on the upper surfaces of one of the side protrusions 42. On the side of the blowing cylinder 40 close to the transparent cover 8, there is a blowing air pipe 43, and on the other side, a sealing and fitting plate 44 is inserted. The sealing and fitting plate 44 is fixed with a connecting round rod 45. At the other end of the connecting round rod 45, there is an open frame 46 installed. A runner 47 is installed in the open frame 46. A fifth spring 48 is sleeved on the connecting round rod 45. Both ends of the fifth spring 48 are in contact connection with the blowing cylinder 40 and the open frame 46 respectively. The two inclined top plates 41 are respectively fixed on the outer sheaths 2 on both sides of the transparent cover 8 through bending plates 49. The inclined top plates 41 are provided with inclined end faces facing the open frame 46. The open frame 46 is sleeved on the inclined top plates 41 and is slidably connected with the inclined end faces of the inclined top plates 41 through the runners 47. Through the setting of the inclined end faces, when the blowing cylinder 40 moves upward, the air in the blowing cylinder 40 can be pushed out by its sealing and fitting plate 44, and the air blows to the surface of the transparent cover 8 through the blowing air pipe 43, so as to blow away the dust. In order to facilitate the replacement of the sponge block 34, an installation insertion block 50 is integrally formed at the lower end of the sponge block 34. On both sides of the installation insertion block 50, side fixing blocks 51 are integrally formed. The wiping vertical plate 38 is provided with side holes 52 below the side protrusions 42. The side fixing blocks 51 are inserted into the side holes 52. The installation insertion block 50 is used to form a connection with the installation slot 39, which is convenient for replacing the sponge block 34.
