Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power operation and maintenance monitoring, specifically, it relates to a power operation and maintenance monitoring device. Background Technology
[0002] Power operation and maintenance monitoring devices refer to equipment used for real-time monitoring and early warning of power equipment during power operation and maintenance.
[0003] Chinese patent CN221943851U discloses a power operation and maintenance monitoring device, comprising: an adjustment mechanism including an auxiliary block, protrusions, a first gear, and a second gear; an auxiliary block fixedly mounted on one side of a fixed block; several uniformly spaced protrusions fixedly mounted on one side of the auxiliary block; a first gear movably mounted on one side of a protrusion via a rotating shaft on the top of a positioning block; and a second gear fixedly mounted on one side of the first gear at the bottom of a support rod, with the first gear meshing with the second gear. This application utilizes several uniformly spaced protrusions to rotate the moving first gear, enabling continuous monitoring of the center of the site while the monitor moves, thus solving the problem of inaccurate monitoring during movement. However, in actual operation and maintenance scenarios, to achieve precise adaptation between the monitor's rotation angle and movement distance, the meshing design of the first gear and protrusions is usually intermittent, and neither the first nor the second gear has a locking structure. During the non-meshing phase, because the monitor is exposed, in extreme environments, such as areas with strong winds, the locking capability for the monitor angle is limited, potentially leading to monitor angle deviation due to strong winds. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a power operation and maintenance monitoring device that solves the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A power operation and maintenance monitoring device, comprising: The support mechanism is equipped with a linear drive mechanism and a linear array with several teeth on one side. A slider whose displacement is driven by a linear drive mechanism, and at least one extrusion block is provided inside the slider; A power operation and maintenance monitoring mechanism that rotates and engages with the lower part of the slider; A first gear for driving the rotation of the power operation and maintenance monitoring mechanism, a circular plate is fixed above the first gear, and the first gear intermittently meshes with the gear; and The annular spring is located inside the circular plate, and there are multiple rotating obstructions on the circumference of the annular spring that are squeezed and displaced by the squeezing blocks.
[0006] Optionally, the support mechanism includes a mounting plate with two bearing seats mounted on one side.
[0007] Optionally, a guide rail is installed on one side of the mounting plate between the two bearing seats, and the slider slides on the guide rail.
[0008] Optionally, the linear drive mechanism includes a motor mounted on one side of the mounting plate, with the motor's output shaft fixedly fitted with a screw, and a slider threadedly fitted around the screw.
[0009] Optionally, the power operation and maintenance monitoring mechanism includes a second gear that rotates and engages with the lower side of the slider. The lower end face of the second gear is provided with a protrusion, and a camera is rotated and engaged with the lower part of the protrusion.
[0010] Optionally, the power operation and maintenance monitoring mechanism also includes bolts and nuts. The lower end face of the protrusion is provided with two clamping plates, and the upper part of the camera is provided with a rotating plate located between the two clamping plates. One end of the bolt passes through the clamping plate and the rotating plate and is threaded into the nut.
[0011] Optionally, the deflector includes a squeeze block extending to the outside of the circular plate, with a push rod slidably fitted inside the circular plate on one side of the squeeze block, the end of the push rod abutting against the side of the annular spring.
[0012] Optionally, anti-detachment strips are provided on both sides of the push rod.
[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: By meshing with the moving first gear, the power operation and maintenance monitoring mechanism is driven to rotate intermittently at a fixed angle, thus achieving angle adjustment during the movement process. Through the synergistic action of the squeezing block, the annular spring, and multiple anti-rotation components, the circumferential restriction on the circular plate is released during the movement of the slider, and the anti-rotation component is reset after passing the squeezing block, ensuring smooth rotation of the power operation and maintenance monitoring mechanism. When the machine stops, the squeezing block mechanically blocks the anti-rotation component, locking the position of the circular plate and the power operation and maintenance monitoring mechanism, thus improving the stability of the monitoring direction.

Detailed Implementation
[0018] 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.
[0019] Please see Figure 1-4 As shown, this embodiment provides a power operation and maintenance monitoring device, including: Support mechanism 1, a linear drive mechanism 2 and a linear array with several teeth 8 are installed on one side of support mechanism 1; The slider 3 is driven to move by the linear drive mechanism 2, and at least one extrusion block 302 is provided inside the slider 3; The power operation and maintenance monitoring mechanism 4 is rotated and fitted to the lower part of the slider 3; The first gear 5 is used to drive the power operation and maintenance monitoring mechanism 4 to rotate. A circular plate 502 is fixed above the first gear 5, and the first gear 5 intermittently meshes with the gear 8. The annular spring 7 is located inside the circular plate 502, and there are multiple rotating obstructions 6 on the circumference of the annular spring 7 that are displaced by the compression of the compression block 302.
[0020] Optionally, a rotating groove 301 is provided on the lower side of the slider 3, and an extrusion block 302 is provided on the side of the rotating groove 301. An extension block 501 is provided between the first gear 5 and the circular plate 502. Both the extension block 501 and the circular plate 502 are rotatably engaged in the rotating groove 301. A limit ring is fixed at the opening of the rotating groove 301 by bolts. The limit ring is located on the periphery of the extension block 501. By cooperating with the extension block 501, the coaxiality of the first gear 5 and the circular plate 502 during rotation is improved, and the effect of positioning the first gear 5 at the bottom of the slider 3 is achieved.
[0021] One application of this embodiment is as follows: When the linear drive mechanism 2 is activated and drives the slider 3 to move along the length direction of the support mechanism 1, the slider 3 drives the first gear 5 and the power operation and maintenance monitoring mechanism 4 to move simultaneously; as the slider 3 moves a certain distance, the first gear 5 is forcibly engaged with one of the teeth 8; since the tooth 8 is fixed, the first gear 5 is forced to rotate by a fixed angle, and the rotation of the first gear 5 drives the circular plate 502 and the power operation and maintenance monitoring mechanism 4 to rotate; at the same time, the rotation of the circular plate 502 drives the rotating resist 6 on the circular plate 502 to rotate around. Its center rotates, and the fixed pressing block 302 forces the rotating obstruction 6 to slide and avoid it. During this process, the obstructing obstruction 6 slides into the circular plate 502 and compresses the annular spring 7 to deform. When the obstruction 6 passes the pressing block 302, the annular spring 7 elastically recovers and pushes the obstruction 6 back to its original position. Repeating the above steps, whenever the power operation and maintenance monitoring mechanism 4 moves a certain distance, it will be driven by the first gear 5, causing the power operation and maintenance monitoring mechanism 4 to rotate and adjust to a specific angle, thus keeping the power operation and maintenance monitoring mechanism 4 facing the monitoring area. After the linear drive mechanism 2 stops working, the pressing block 302 is used to lock between the two rotating obstructions 6, restricting the rotation of the circular plate 502, thereby locking the first gear 5 and realizing the positioning of the power operation and maintenance monitoring mechanism 4. It should be noted that all electrical equipment involved in this application can be powered by a battery or an external power source.
[0022] By meshing the gear 8 with the moving first gear 5, the power operation and maintenance monitoring mechanism 4 is driven to rotate intermittently at a fixed angle, thus realizing angle adjustment during the movement process; through the synergistic action of the pressing block 302, the annular spring 7, and multiple rotating obstruction components 6, the circumferential restriction on the circular plate 502 is released during the movement of the slider 3, and the rotating obstruction component 6 is reset after passing the pressing block 302, ensuring smooth rotation of the power operation and maintenance monitoring mechanism 4; by mechanically blocking the rotating obstruction component 6 with the pressing block 302 when the machine stops, the position of the circular plate 502 and the power operation and maintenance monitoring mechanism 4 is locked, improving the stability of the monitoring direction.
[0023] like Figure 1 , 2As shown, the support mechanism 1 in this embodiment includes a mounting plate 101. Two bearing seats 102 are mounted on one side of the mounting plate 101. The bearings in the bearing seats 102 are deep groove ball bearings. Gear 8 is mounted on the lower part of one side of the mounting plate 101, and gear 8 is located below the slider 3. Optionally, a guide rail 103 is mounted on one side of the mounting plate 101 between the two bearing seats 102. The slider 3 slides on the guide rail 103. The straightness error of the guide rail 103 is ≤0.05mm / m, and the gap between the slider 3 and the guide rail 103 is 0.01~0.1mm, reducing the probability of misalignment between the first gear 5 and gear 8 due to excessive gap. The guide rail 103 provides linear guidance for the slider 3, limiting the nonlinear displacement of the slider 3 and ensuring the meshing of the first gear 5 and gear 8.
[0024] like Figure 1 As shown, the linear drive mechanism 2 in this embodiment includes a motor 201 mounted on one side of the mounting plate 101. The motor 201 rotates at a speed of 100-300 rpm to avoid excessive inertia of the slider 3 causing meshing impact. The output shaft of the motor 201 is fixedly fitted with a screw 202. The two ends of the screw 202 are respectively located in two bearing seats 102. The slider 3 is threaded onto the periphery of the screw 202. The screw 202 adopts a Tr16×4 trapezoidal thread. The motor 201 drives the screw 202 to rotate, and the screw 202 drives the slider 3 to slide, which facilitates the control of the movement distance of the power operation and maintenance monitoring mechanism 4. The self-locking characteristic of the screw 202 is used to position the slider 3 when the machine stops, preventing displacement deviation caused by gravity or vibration and improving positioning reliability. The two bearing seats 102 provide dual-point support for the screw 202, improving the transmission stability of the linear drive mechanism 2.
[0025] like Figure 2As shown, the power operation and maintenance monitoring mechanism 4 in this embodiment includes a second gear 401 rotatably engaged with the lower side of the slider 3. The second gear 401 meshes with a first gear 5, which is located between the second gear 401 and the mounting plate 101. A protrusion 402 is provided on the lower end face of the second gear 401, and a camera 404 is rotatably engaged with the lower part of the protrusion 402. Optionally, it also includes a bolt 406 and a nut 407. Two clamping plates 403 are provided on the lower end face of the protrusion 402, and a rotating plate 405 is provided on the upper part of the camera 404 between the two clamping plates 403. One end of the bolt 406 passes through the clamping plate 403 and the rotating plate 405 and is threaded into the nut 407. The friction coefficient between the clamping plate 403 and the rotating plate 405 is 0.1 to 0.3, and the surfaces are sandblasted or coated with rubber to balance the clamping force and the smoothness of manual adjustment. In use, tightening bolt 406 and nut 407 causes the head of bolt 406 and nut 407 to press against the two clamping plates 403, causing slight deformation of the two clamping plates 403 to clamp the rotating plate 405, restricting the rotation of the rotating plate 405 between the two clamping plates 403; conversely, loosening bolt 406 and nut 407 allows for adjustment of the rotation of the rotating plate 405. The meshing transmission of the first gear 5 and the second gear 401 facilitates the horizontal angle adjustment of the camera 404 in the opposite direction when the slider 3 slides, thus ensuring that the power operation and maintenance monitoring mechanism 4 remains facing the monitoring area. The cooperation between the clamping plates 403 and the rotating plate 405 with bolt 406 and nut 407 facilitates manual fine-tuning of the camera 404's pitch angle, enhancing its adaptability to complex monitoring scenarios.
[0026] like Figure 4 As shown, the anti-rotation component 6 in this embodiment includes a squeeze block 601 extending outside the circular plate 502. The contact areas of the squeeze block 601 and the squeezing block 302 are rounded. A push rod 602 is provided on one side of the squeeze block 601, which is slidably fitted in the circular plate 502. The end of the push rod 602 abuts against the side of the annular spring 7. The contact end between the push rod 602 and the annular spring 7 is narrowed and rounded. Optionally, anti-detachment strips 603 are provided on both sides of the push rod 602. Optionally, a movable groove 503 is provided in the circular plate 502. The annular spring 7 and the anti-detachment strips 603 are both located in the movable groove 503. The side of the circular plate 502 is provided with multiple storage grooves 504. The end of the squeeze block 601 near the push rod 602 is located in the storage groove 504. A sliding groove 505 is provided between the storage groove 504 and the movable groove 503, and the push rod 602 passes through the sliding groove 505. The rounded corners of the contact surfaces between the squeeze block 601 and the extrusion block 302 reduce frictional resistance and extend the service life of the anti-rotation component 6; the narrowing and rounded corner design at the end of the push rod 602 prevents obstruction of movement between adjacent push rods 602; and the anti-detachment strip 603 limits the push rod 602 from coming out of the slide groove 505, ensuring the long-term reliability of the anti-rotation function and reducing maintenance requirements.
