Description

Technical Field

[0001] This utility model relates to the field of inspection devices, and in particular to an inspection device with an adjustable gimbal. Background Technology

[0002] Currently, in fields such as security patrol and industrial monitoring, fixed or simply rotating camera equipment is commonly used for area surveillance. These devices typically lack multi-degree-of-freedom adjustment capabilities, making it difficult to flexibly adapt to the shooting needs of complex environments. While some existing pan-tilt units can achieve a certain angle of rotation, most have simple structures, cannot move smoothly or make large-scale position adjustments, and lack effective telescopic mechanisms. This results in limited coverage and insufficient adjustment flexibility, making it difficult to meet the requirements of high-efficiency, all-around inspection operations. Therefore, there is an urgent need for a new type of inspection device with multi-directional adjustment capabilities, stable operation, and strong adaptability. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The purpose of this utility model is to provide an inspection device with an adjustable gimbal to solve the problems existing in the prior art, and it has a wide coverage, flexible adjustment and can adapt to various complex inspection scenarios.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1-12As shown, this utility model provides an adjustable pan-tilt inspection device, including: a mounting frame 7, a camera device 45, a slide rail adjustment structure, a connecting frame 14, a push rod adjustment structure, a rotation adjustment structure, and an angle adjustment structure. The mounting frame 7 is mounted on a slide rail 1 via the slide rail adjustment structure, which drives the mounting frame 7 to slide along the slide rail 1. The mounting frame 7 is connected to the fixed end of the push rod adjustment structure, and the output end of the push rod adjustment structure is connected to the connecting frame 14, driving the connecting frame 14 to move in a direction perpendicular to the slide rail 1. The connecting frame 14 is used to mount the rotation adjustment structure, and the output end of the rotation adjustment structure is connected to the camera device 45, used to adjust the rotation angle of the camera device 45. An angle adjustment structure is also mounted on the connecting frame 14 to adjust the tilt angle of the camera device 45. This utility model achieves position adjustment of the camera device 45 on a two-dimensional plane through the slide rail adjustment structure and the push rod adjustment structure, and achieves complete spherical space angle adjustment capability through the rotation adjustment structure and the angle adjustment structure. These four sets of adjustment structures work together to form a system that can adjust "position" and "posture" in space with four degrees of freedom. It has a wide coverage, flexible adjustment, and can adapt to various complex inspection scenarios.

[0035] In one embodiment, the slide rail adjustment structure includes a rack 2, a slide table 3, a first servo motor 5, and a first gear 6. The slide table 3 is mounted on a mounting frame 7, and the rack 2 is mounted on the slide rail 1. The slide table 3 is slidably connected to the slide rail 1. The first servo motor 5 and the first gear 6 are mounted on the slide table 3, and the output shaft of the first servo motor 5 is connected to the first gear 6. The first gear 6 meshes with the rack 2. Under the driving action of the first servo motor 5, the first gear 6 can be driven to mesh with the rack 2, thereby driving the slide table 3 to slide on the slide rail 1.

[0036] Furthermore, the slide rail adjustment structure adopts a friction drive method, including a hydraulic motor, an active friction wheel, a driven clamping wheel, and an elastic clamping device. The hydraulic motor is fixedly mounted on the slide table 3. The active friction wheel is directly mounted on the output shaft of the hydraulic motor. The driven clamping wheel is mounted on the slide table 3 through a bearing seat, with its axis parallel to the active friction wheel. The elastic clamping device (which can be a compression spring or a cylinder) acts on the bearing seat of the driven clamping wheel, providing an adjustable or constant pressure, so that the active friction wheel and the driven clamping wheel tightly clamp the slide rail 1 from the top and bottom. The working process is as follows: the elastic clamping device applies pressure, causing the active friction wheel and the driven clamping wheel to clamp the slide rail. The hydraulic motor rotates, driving the active friction wheel to rotate. Through the friction between the active friction wheel and the surface of the slide rail, the slide table 3, along with the mounting frame 7 and all its components, moves along the slide rail 1.

[0037] In one embodiment, the push rod adjustment structure is an electric push rod 13. The fixed end of the electric push rod 13 is connected to the mounting frame 7, and the output end of the electric push rod 13 is connected to the connecting frame 14. Under the driving action of the electric push rod 13, the connecting frame 14 can be pushed to move in a direction perpendicular to the slide rail 1. The connecting frame 14 drives the camera device 45 to move synchronously. It can be understood that when the slide rail 1 is set in a horizontal direction, the push rod adjustment structure can realize convenient adjustment of the working height of the camera device 45.

[0038] Furthermore, the push rod adjustment structure includes a third servo motor, a coupling, a ball screw, a screw nut, and a guide mechanism. The third servo motor is fixedly mounted on the mounting frame 7 via a motor mount. The ball screw is supported on the mounting frame 7 via a bearing seat. The axis of the ball screw is perpendicular to the direction of the slide rail. The output shaft of the third servo motor and one end of the ball screw are connected via a coupling. The screw nut meshes with the ball screw. The guide mechanism can use at least one optical shaft and a matching linear bearing. The optical shaft is installed parallel to the ball screw. The screw nut and a connecting block are fixed. The connecting block is also fixed to the linear bearing, thus ensuring that the connecting block can only move along the optical shaft axial direction. The connecting frame 14 is fixedly connected to the connecting block. After receiving the control signal, the third servo motor starts to rotate and drives the ball screw to rotate via the coupling. The rotation of the ball screw is converted into the linear motion of the screw nut. Due to the limitation of the guide mechanism, the screw nut drives the connecting block and the connecting frame 14 to perform precise linear extension and retraction together.

[0039] As one embodiment, the rotation adjustment structure includes a second servo motor 15, a sealing plate 16, a connecting plate 17, and a support plate 18. The output shaft of the second servo motor 15 is connected to the sealing plate 16. The sealing plate 16 is rotatably connected to the connecting frame 14 via a bearing. The center position of the bottom surface of the sealing plate 16 is connected to the connecting plate 17. The bottom end of the connecting plate 17 is hinged to the support plate 18. The camera device 45 is connected to the bottom end face of the support plate 18.

[0040] In one embodiment, the angle adjustment structure includes an internal gear 27, a sleeve 22, a reciprocating screw 19, a push plate 20, and a limiting block 21. The internal gear 27 is annular and fixed to the inner wall of the top of the connecting frame 14. The reciprocating screw 19 is mounted on the sealing plate 16 and rotatably connected to it. The push plate 20 is threaded onto the reciprocating screw 19. The push plate 20 has an L-shaped cross-section and penetrates the sealing plate 16. The bottom end of the push plate 20 is hinged to the limiting block 21. The limiting block 21 has a T-shaped cross-section and is slidably connected to the support. On plate 18, sleeve 22 is rotatably connected to the top of reciprocating screw 19. Spring 23 is provided inside sleeve 22, and a locking block 24 is fixedly connected to spring 23. The top of reciprocating screw 19 is provided with a locking groove 25 corresponding to locking block 24. One end of locking block 24 is rotatably connected inside sleeve 22, and the other end of locking block 24 is engaged in locking groove 25. The end of locking block 24 that engages with locking groove 25 is an inclined surface, and the inner wall of locking groove 25 is also an inclined surface. A second gear 26 is provided outside sleeve 22, which is used to mesh with internal gear 27.

[0041] Furthermore, the second servo motor 15 drives the sealing plate 16 to rotate counterclockwise. At this time, the sealing plate 16 can drive the support plate 18 to rotate synchronously through the connecting plate 17, thereby enabling convenient adjustment of the rotation angle of the camera device 45 in the direction parallel to the slide rail 1. During the counterclockwise rotation of the sealing plate 16, it can drive the reciprocating screw 19 to rotate counterclockwise. Under the action of the reciprocating screw 19, it can drive the second gear 26 to rotate synchronously through the sleeve 22. Since the second gear 26 rotates clockwise during its counterclockwise rotation and meshes with the internal gear 27, the second gear 26 rotates clockwise. Therefore, under the action of the clockwise rotation of the second gear 26, it can drive each locking block 24 to move along the inclined surface of the inner wall of the slot 25 through the sleeve 22. The sleeve 22 will not drive the reciprocating screw 19 to rotate. Therefore, the camera device 45 can stably adjust the rotation angle in the direction parallel to the slide rail 1.

[0042] Furthermore, when it is necessary to adjust the tilt angle of the camera device 45, the second servo motor 15 simply drives the sealing plate 16 to rotate clockwise. Similarly, under the rotation of the sealing plate 16, the sleeve 22 on the reciprocating screw 19 drives the second gear 26 to rotate clockwise. By meshing with the internal gear 27, the second gear 26 rotates counterclockwise. Under the counterclockwise rotation of the second gear 26, the various locking blocks 24 on the sleeve 22 can be stably locked into the slots 25, and the reciprocating screw 19 can be moved. The reciprocating screw 19 rotates, driving the push plate 20 to move up and down in a cyclical motion. This up-and-down motion of the push plate 20, through the limiting block 21 hinged at the bottom of the push plate 20, causes the support plate 18 to rotate around the bottom hinge point of the connecting plate 17, thus adjusting the tilt angle of the camera device 45. Once the tilt angle of the camera device 45 is adjusted, the clockwise rotation of the sealing plate 16 stops, and then the sealing plate 16 can rotate counterclockwise again, driving the camera device 45 to complete subsequent inspections. By controlling the forward and reverse rotation of the output shaft of the second servo motor 15, the rotation angle and tilt angle of the camera device 45 can be adjusted respectively. It can be understood that by changing the tilt direction of the inclined surfaces of the card block 24 and the inner wall of the card slot 25, the second servo motor 15 can be changed whether it drives the sealing plate 16 to rotate clockwise or counterclockwise when adjusting the tilt angle of the camera device 45.

[0043] As one embodiment, a heat dissipation structure is also included, which includes a protective frame 30 and a liquid storage tank 32. The protective frame 30 is connected to the bottom of the support plate 18. Second filter plates 43 are provided on both sides of the protective frame 30. Tempered glass 44 is fixedly connected to the protective frame 30. A ventilation tube 34 is provided at the bottom of the protective frame 30. A desiccant plate 36, an exhaust fan 38, a rotating ring 40 and a first filter plate 35 are arranged in sequence inside the ventilation tube 34. Through holes 41 are provided at both ends of the rotating ring 40 in the radial direction. A sponge rod 42 is arranged in the radial direction of the rotating ring 40 at the position of the through hole 41. A connecting pipe 33 is fixedly connected to the bottom of the liquid storage tank 32. The connecting pipe 33 is connected to the through hole 41. The rotating ring 40 and the inner wall of the ventilation tube 34 are rotatably connected by a bearing. A radially fixed rod 39 is also fixedly connected inside the rotating ring 40. The exhaust fan 38 and the fixed rod 39 are both connected to the output shaft of the drive motor 37.

[0044] Driven by the drive motor 37, the continuous rotation of the exhaust fan 38 draws air through the ventilation duct 34 and exhausts it through the second filter plate 43 on the protective frame 30, thus circulating air within the protective frame 30 and achieving ventilation and heat dissipation for the camera equipment 45. The combined action of the first filter plate 35 and the desiccant plate 36 filters and removes dust, impurities, and moisture from the air, preventing them from entering the camera equipment 45 and causing damage.

[0045] Furthermore, during the operation of the drive motor 37, that is, during the rotation of the rotating ring 40, the through hole 41 can be intermittently aligned with the connecting pipe 33. At this time, the water in the liquid storage tank 32 can automatically and intermittently permeate into the sponge rod 42 through the connecting pipe 33 and the through hole 41. Under the continuous air circulation, the evaporation of water absorbs heat, which can further improve the heat dissipation efficiency and effect, and ensure the stability and safety of the camera equipment 45 during long-term operation.

[0046] As one embodiment, the protective frame 30 has slots 31 on both sides of its side walls, and the support plate 18 has a two-way threaded rod 28 at both ends. The two-way threaded rod 28 is threaded with a plug plate 29. One end of the plug plate 29 is provided with a protrusion for insertion into the slot 31. The two-way threaded rod 28 can drive the plug plate 29 to move radially along the slot 31.

[0047] Furthermore, the support plate 18 has an internal cavity, and two bidirectional threaded rods 28 are rotatably connected to both ends of the support plate 18. The bidirectional threaded rods 28 are located in the internal cavity of the support plate 18, and insert plates 29 are threaded onto the bidirectional threaded rods 28. The insert plates 29 penetrate the bottom end face of the support plate 18, and the bidirectional threaded rods 28 can drive the insert plates 29 to reciprocate. The bottom end face of the support plate 18 has an opening for the insert plates 29 to move. Rotating the bidirectional threaded rods 28 causes the insert plates 29 to extend into or separate from the slots 31, thereby realizing the disassembly or installation of the protective frame 30. Through the rotation of the bidirectional threaded rods 28, combined with the insert plates 29 and the slots 31, the disassembly and installation of the protective frame 30 can be easily completed, thus ensuring the convenience of inspection and maintenance of the protective frame 30 and its internal parts. Furthermore, the convenient disassembly of the protective frame 30 ensures the convenience of subsequent disassembly, assembly, and maintenance of the camera equipment 45. The clamping of the protective frame 30 by the insert plates 29 ensures the stability of the protective frame 30 in the locked installation state.

[0048] As one embodiment, the system also includes a solar photovoltaic panel 4, a mounting plate 10 fixed on a mounting frame 7, and a battery 9, an inverter 8, a wireless communication module 12, and a central control module 11 disposed inside the mounting frame 7. The solar photovoltaic panel 4 is electrically connected to the battery 9. Under the action of the solar photovoltaic panel 4, solar energy can be converted into light energy, which is then stored in the battery 9 through the inverter 8 to provide power for the inspection device.

[0049] As one implementation, ball bearings are installed inside the slide table 3, and the ball bearings are in contact with the slide rail 1. The rolling action of the ball bearings ensures the stability of the movement of the inspection device.

[0050] As one embodiment, a damping hinge is provided between the support plate 18 and the connecting plate 17. The damping hinge includes a first connecting part and a second connecting part that are hinged to each other. The first connecting part is fixedly connected to the connecting plate 17, and the second connecting part is fixedly connected to the support plate 18. A friction plate and a preload spring are provided at the hinge of the first connecting part and the second connecting part to provide rotational damping force.

[0051] The working process of the adjustable gimbal inspection device in one embodiment of this utility model is as follows: The slide rail 1 is set horizontally, and the mounting frame 7, connecting frame 14, support plate 18 and their internal parts are assembled into a gimbal assembly. Under the driving action of the first servo motor 5, the first gear 6 can be driven to mesh with the rack 2, thereby driving the slide table 3 to slide on the slide rail 1. Under the driving action of the electric push rod 13, the connecting frame 14 is pushed to move up or down. Through the connecting plate 17 and support plate 18, the camera equipment 45 can be driven to move synchronously, realizing convenient adjustment of the working height of the camera equipment 45; and under the driving action of the second servo motor 15, the sealing plate 16 can be driven to move counterclockwise through the output shaft. When the needle rotates, the sealing plate 16 can drive the support plate 18 to rotate synchronously through the connecting plate 17, thereby enabling convenient adjustment of the horizontal angle of the camera device 45. The sealing plate 16 drives the reciprocating screw 19 to rotate counterclockwise, which in turn drives the second gear 26 to rotate synchronously through the sleeve 22. Under the meshing with the internal gear 27, the second gear 26 rotates clockwise. Therefore, under the clockwise rotation of the second gear 26, the sleeve 22 can drive each locking block 24 to move along the inclined surface of the inner wall of the slot 25. The sleeve 22 will not drive the reciprocating screw 19 to rotate. Therefore, the camera device 45 can stably adjust the rotation angle in the direction parallel to the slide rail 1.

[0052] When the tilt angle of the camera device 45 needs to be adjusted, the second servo motor 15 simply drives the sealing plate 16 to rotate clockwise. Similarly, the rotation of the sealing plate 16 drives the second gear 26 to rotate clockwise through the sleeve 22 on the reciprocating screw 19. By meshing with the internal gear 27, the second gear 26 rotates counterclockwise. Under the counterclockwise rotation of the second gear 26, the various locking blocks 24 on the sleeve 22 can be stably locked into the slots 25, and the reciprocating screw 19 can be moved to... The rotation of the reciprocating screw 19 drives the push plate 20 to perform cyclic up-and-down reciprocating motion. Under the action of the up-and-down reciprocating motion of the push plate 20, the limiting block 21 hinged at the bottom of the push plate 20 drives the support plate 18 to rotate around the bottom hinge point of the connecting plate 17, thereby adjusting the tilt angle of the camera device 45. After the tilt angle of the camera device 45 is adjusted, the clockwise rotation of the sealing plate 16 can be stopped, and then the sealing plate 16 can rotate counterclockwise again, driving the camera device 45 to complete the subsequent inspection. Driven by the electric push rod 13 and the second servo motor 15, the working height, horizontal angle and tilt angle of the pan-tilt assembly can be easily adjusted, thereby enabling multi-angle and multi-position adjustment of the entire inspection device. The camera device 45, through the tempered glass 44, can perform a comprehensive and detailed inspection of the equipment in the substation.

[0053] When the camera equipment 45 needs to be inspected and maintained, the staff only needs to rotate the bidirectional threaded rod 28 inside the support plate 18 to drive the insert plates 29 connected by threads on both sides to move to the side at the same time and disengage them from the slots 31 on the protective frame 30, so that the disassembly of the protective frame 30 can be easily completed. Then the staff can disassemble and inspect the camera equipment 45. Similarly, after the camera equipment 45 is inspected and maintained, it can be fixed to the support plate 18 with bolts. Then the staff only needs to rotate the bidirectional threaded rod 28 in the opposite direction to drive the insert plates 29 to be inserted into the slots 31 on the protective frame 30. At the same time, the insert plates 29 clamp the protective frame 30 to ensure the stability of the protective frame 30 in the locked installation state.

[0054] Driven by the drive motor 37, the exhaust fan 38 and the rotating ring 40 on the fixed rod 39 can be rotated simultaneously through the output shaft. Under the continuous rotation of the exhaust fan 38, air can be drawn in through the ventilation duct 34 and exhausted through the second filter plate 43 on the protective frame 30, thereby enabling air to circulate within the protective frame 30 and achieving ventilation and heat dissipation for the camera device 45. At the same time, during the rotation of the rotating ring 40, the through holes 41 on both sides can be intermittently aligned with the connecting pipes 33 on both sides. At this time, the water in the liquid storage tank 32 can automatically and intermittently permeate into the sponge rod 42 through the connecting pipes 33 and the through holes 41. Subsequently, under the continuous air circulation, the evaporation of water absorbs heat, which can further improve the heat dissipation efficiency and effect, ensuring the stability and safety of the camera device 45 during long-term operation.
