Technical Field

[0001] This utility model relates to the technical field of inspection robot accessories, specifically a camera adjustment device for inspection robots. Background Technology

[0002] Inspection robots have been widely used in numerous fields such as industrial production, power systems, and security monitoring. They can replace manual labor in completing dangerous, repetitive, and complex inspection tasks, improving work efficiency and safety. Cameras, as crucial sensing devices for inspection robots, are used to acquire image and video information of the inspection area, playing a key role in the accuracy of inspection results. Currently, to ensure that the camera captures sufficient footage and can complete inspections in different scenarios, adjustment devices are typically installed on the inspection robot to adjust the camera's shooting direction, position, and other parameters.

[0003] The existing camera installation methods for inspection robots are mostly fixed, making it difficult to flexibly adjust them according to changes in the actual inspection scenario. When facing target objects at different angles, the cameras cannot focus well and capture clear images, resulting in missing or inaccurate inspection information in some areas.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a camera adjustment device for inspection robots. Utility Model Content

[0005] The purpose of this invention is to provide a camera adjustment device for inspection robots to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a camera adjustment device for an inspection robot, comprising a height adjustment mechanism and a fixing frame. An electric push rod is disposed on the top right side of the height adjustment mechanism, and a sliding frame is hinged to the top of the electric push rod. An electric push rod is disposed on the top left side of the height adjustment mechanism, and a sliding block is hinged to the top of the electric push rod. The fixing frame is disposed on the top of the sliding frame, and a focus adjustment mechanism is mounted on the top of the fixing frame. The focus adjustment mechanism includes a fixing plate, a rotating ring, a forward / reverse motor, a drive shaft, a gear, and a clamp. The device includes a holder, a gear ring, a second gear, a second drive shaft, and a second reversible motor. A rotating ring is installed inside the bearing at the opening on the surface of the fixed plate. A first reversible motor is installed on the right side of the rotating ring, and the output end of the first reversible motor is connected to a first drive shaft. A first gear is installed outside the first drive shaft, and a clamping device is connected to the outside of the first gear. A gear ring is fixedly fitted around the outside of the rotating ring, and a second gear is connected to the outside of the gear ring. The second drive shaft passes through the middle of the second gear, and a second reversible motor is installed at the left end of the second drive shaft. A distance sensor and a light sensor are installed on the top of the fixed plate.

[0007] Furthermore, the height adjustment mechanism includes a mounting base, a servo motor, and a ball screw, with the servo motor located on the left side of the mounting base, and the output end of the servo motor connected to the ball screw.

[0008] Furthermore, the height adjustment mechanism also includes a lead screw nut, a mounting block, and a support rod, with the lead screw nut externally connected to the ball screw, the mounting block externally provided with the lead screw nut, and the support rod hinged to the top of the mounting block.

[0009] Furthermore, the height adjustment mechanism also includes support rod two, support rod three, and lifting seat, with support rod two hinged to the other end of support rod one, lifting seat hinged to the top of support rod two, and support rod three hinged to the bottom of lifting seat.

[0010] Furthermore, the end of the ball screw furthest from the servo motor is rotatably connected to the mounting base, and the end of the support rod furthest from the lifting seat is hinged to the mounting base.

[0011] Furthermore, the second and third support rods are parallel to each other, and the mounting base and the lifting seat are parallel to each other.

[0012] Furthermore, the second reversible motor is located on the left side of the fixed plate, and the mounting base and the fixed plate are perpendicular to each other.

[0013] This utility model provides a camera adjustment device for an inspection robot, which has the following advantages:

[0014] 1. The distance sensor and light sensor of this utility model are used to collect distance and light information of the inspection scene in real time. The controller sends control commands to the first forward and reverse motor according to the data collected by the distance sensor and light sensor. The second forward and reverse motor drives the second drive shaft and the second gear to rotate, which drives the gear ring to rotate. The gear ring, rotating ring and clamping parts transmit power to the focus adjustment ring of the camera to realize the automatic adjustment of the camera focus. This ensures that the camera can capture clear and accurate images in different environments, and provides reliable data support for subsequent inspection analysis.

[0015] 2. This utility model uses a servo motor to drive the ball screw to rotate, which in turn causes the screw nut and mounting block to move laterally. This causes the angle of support rod one to change gradually, which in turn causes support rod two and support rod three to rotate, generating an upward supporting force on the lifting seat. This helps the camera mounted on the fixed frame to reach a higher height, greatly improving the comprehensiveness of the inspection. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 4As shown, a camera adjustment device for an inspection robot includes a height adjustment mechanism 1 and a mounting bracket 6. An electric push rod 2 is located on the top right side of the height adjustment mechanism 1, and a slide rail 4 is hinged to the top of the electric push rod 2. An electric push rod 3 is located on the top left side of the height adjustment mechanism 1, and a sliding block 5 is hinged to the top of the electric push rod 3. The mounting bracket 6 is located on top of the slide rail 4, and a focus adjustment mechanism 7 is mounted on top of the mounting bracket 6. The focus adjustment mechanism 7 includes a fixed plate 701, a rotating ring 702, a first reversible motor 703, a first drive shaft 704, a first gear 705, a clamping member 706, a gear ring 707, a second gear 708, a second drive shaft 709, and a second reversible motor 710. The shaft at the opening on the surface of the fixed plate 701... A rotating ring 702 is provided inside the bearing. A first reversible motor 703 is provided on the right side of the rotating ring 702. The output end of the first reversible motor 703 is connected to a first drive shaft 704. A first gear 705 is provided on the outside of the first drive shaft 704. A clamping member 706 is connected to the outside of the first gear 705. A gear ring 707 is sleeved and fixed on the outside of the rotating ring 702. A second gear 708 is connected to the outside of the gear ring 707. A second drive shaft 709 passes through the middle of the second gear 708. A second reversible motor 710 is provided on the left end of the second drive shaft 709. A distance sensor 8 and a light sensor 9 are installed on the top of the fixed plate 701. The second reversible motor 710 is located on the left side of the fixed plate 701. The mounting base 101 and the fixed plate 701 are perpendicular to each other.

[0023] The specific operation is as follows: distance sensor 8 and light sensor 9 are used to collect distance and light information of the inspection scene in real time. According to the data collected by distance sensor 8 and light sensor 9, the controller sends control commands to the first reversible motor 703. The second reversible motor 710 drives the second drive shaft 709 and the second gear 708 to rotate, which drives the gear ring 707 to rotate. The gear ring 707, rotating ring 702 and clamping part 706 transmit power to the camera's focus adjustment ring to realize the automatic adjustment of the camera's focus. This ensures that the camera can capture clear and accurate images in different environments, providing reliable data support for subsequent inspection analysis.

[0024] like Figure 1As shown, the height adjustment mechanism 1 includes a mounting base 101, a servo motor 102, and a ball screw 103. The servo motor 102 is located on the left side of the mounting base 101, and the output end of the servo motor 102 is connected to the ball screw 103. The height adjustment mechanism 1 also includes a screw nut 104, a mounting block 105, and a support rod 106. The screw nut 104 is externally connected to the ball screw 103, and the mounting block 105 is externally located on the screw nut 104. The support rod 106 is hinged to the top of the mounting block 105. The height adjustment mechanism 1 also includes a support rod 106. The system includes a second support rod 107, a third support rod 108, and a lifting seat 109. The other end of the first support rod 106 is hinged to the second support rod 107. The top end of the second support rod 107 is hinged to the lifting seat 109, and the bottom of the lifting seat 109 is also hinged to the third support rod 108. The end of the ball screw 103 away from the servo motor 102 is rotatably connected to the mounting base 101, and the end of the third support rod 108 away from the lifting seat 109 is hinged to the mounting base 101. The second support rod 107 and the third support rod 108 are parallel to each other, and the mounting base 101 and the lifting seat 109 are parallel to each other.

[0025] The specific operation is as follows: the servo motor 102 drives the ball screw 103 to rotate, which drives the screw nut 104 and the mounting block 105 to move laterally, so that the angle of the first support rod 106 changes slowly, which drives the second support rod 107 and the third support rod 108 to rotate and generate an upward support force on the lifting seat 109, thereby helping the camera installed on the fixed frame 6 to reach a higher height and greatly improving the comprehensiveness of the inspection.

[0026] In summary, when using the camera adjustment device for the inspection robot, firstly, mounting holes for connecting the inspection robot body and the camera are reserved on the mounting base 101 and the fixing frame 6, respectively. After mounting the mounting base 101 on the upper surface of the inspection robot body, the camera lens is inserted through the rotating ring 702, and the clamping member 706 is adjusted to the positions on both sides of the camera focal length adjustment ring. Then, the forward and reverse motor 703 is started, which drives the drive shaft 704 and the gear 705 to rotate. The gear 705 drives the clamping member 706 to slide in the through grooves on both sides of the rotating ring 702 until the clamping members 706, which are close to each other, clamp the camera focal length adjustment ring. Then, the camera is connected to the fixing frame 6.

[0027] In automatic inspection mode, the inspection robot travels along the preset inspection route. The distance sensor 8 and the light sensor 9 collect the distance and light information of the inspection scene in real time and transmit the data to the controller. The controller sends control commands to the servo motor 102, electric push rod 1 2, electric push rod 2 3, and forward and reverse motor 2 710 based on the data collected by the distance sensor 8 and the light sensor 9.

[0028] The servo motor 102 drives the ball screw 103 to rotate, causing the screw nut 104 and mounting block 105 to move laterally. This causes the angle of support rod 106 to change gradually, which in turn causes support rods 107 and 108 to rotate, generating an upward supporting force on the lifting seat 109. This helps the camera mounted on the fixed frame 6 reach a higher height, greatly improving the comprehensiveness of the inspection. By controlling the retraction of electric push rod 12 and the extension of electric push rod 23, or by extending electric push rod 12 and retracting electric push rod 23, the sliding block 5 can slide within the groove on the surface of the slide frame 4. This causes the slide rail 4 to rotate, allowing the camera to shoot at different angles, expanding the camera's shooting range and reducing blind spots during inspections. The forward and reverse motor 710 drives the drive shaft 709 and gear 708 to rotate, which in turn drives the gear ring 707. The gear ring 707, rotating ring 702, and clamping member 706 transmit power to the camera's focus adjustment ring, enabling automatic adjustment of the camera's focus. This ensures that the camera can capture clear and accurate images in different environments, providing reliable data support for subsequent inspection analysis. This adapts to various inspection scenarios and greatly improves the comprehensiveness of inspections.
