Description

Technical Field

[0001] This invention relates to the field of power monitoring equipment technology, specifically to a power monitoring device for power engineering. Background Technology

[0002] Because power transmission cables are exposed to harsh outdoor environments for extended periods, their surface insulation layers are prone to damage. Visual damage inspection of high-voltage power transmission cables is essential to detect and eliminate potential defects before they escalate into serious accidents such as power outages, fires, or even collapses. This preventative maintenance measure is crucial for ensuring a safe and stable power supply, preventing huge economic losses, and maintaining the normal operation of society.

[0003] A search revealed Chinese patent CN118281761B, which describes a new energy power monitoring device for power engineering. Through the cooperation of a drive ring frame on both sides and a detection plate frame, the device can drive the detection module to move along a limiting steel cable during the detection process, performing detection on the cable under test. Furthermore, the detection plate frame rotates along the direction of the drive ring frame during the translational movement of the detection plate frame, enabling comprehensive detection of the cable under test and improving the device's detection range and accuracy.

[0004] However, in real-world scenarios, cables are not always taut; they naturally sag in an arc between adjacent towers. During the comprehensive inspection process involving rotation around the cable, the relative distance between the detection module and the cable constantly changes, leading to variations in the cable size and resolution in the captured images. This results in a lack of standardized parameters in the acquired image information, making data standardization difficult and reducing the accuracy of damage location. Furthermore, since the above method does not contact the cable surface, the cable itself, due to its sag, may experience compression and closure at the damaged area. Additionally, the cable surface exposed to the external environment is prone to adhering to impurities. These issues all contribute to increased difficulty and error in image acquisition. Summary of the Invention

[0011] Preferably, the pulley, the threaded ring, and the fixing seat are all penetrated by the cable body and sleeved on the outer contour of the cable body, and the multiple locking blocks and the limiting grooves are correspondingly adapted and slidably connected.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please see Figures 1 to 9 The present invention provides a technical solution: a power monitoring device for power engineering, comprising a cylinder 1, characterized in that: it further comprises a power mechanism for completing image acquisition and a traveling component for realizing the movement of the device, a positioning frame 11 is fixedly connected to the inner wall of the top side of the cylinder 1, a counterweight 12 is fixedly connected to the inner wall of the bottom of the cylinder 1 on the same side as the positioning frame 11, a plurality of equally spaced and circumferentially distributed sliding grooves 13 are opened on the inner wall of the cylinder 1 on the opposite side from the positioning frame 11, and a cable 14 is transversely penetrating the non-center part of the upper half of the cylinder 1; The traveling assembly includes a telescopic mechanism for cleaning the cable surface and a clamping mechanism for traveling. The telescopic mechanism includes a cylindrical cam 3 sleeved on the outer contour of the cable body 14, and the clamping mechanism includes a transmission belt 5 and a transmission belt 6 that are connected to the telescopic mechanism.

[0021] In this scheme, the cable body 14 serves as the cable to be tested. The installation of the device is achieved by attaching the entire device to the outside of the cable. The cylinder 1, the power mechanism, and the traveling component are all assembled and snapped together in two halves to facilitate personnel to freely disassemble and assemble the device. The positioning frame 11 limits and fixes the power mechanism. The counterweight 12 works with the traveling component to prevent the device from deviating during its travel. The slide 13 further works to complete the movement process of the traveling component.

[0022] Furthermore, while providing power to the traveling component, the power mechanism itself revolves around the cable body 14, thereby achieving a fixed-distance circumferential monitoring effect on the cable body 14 and completing the comprehensive acquisition of information about the cable body 14's exterior. The traveling component achieves creeping movement by extending and retracting and intermittently locking with the cable body 14, thereby reducing the risk of slippage and jamming. At the same time, it wipes and cleans the surface of the cable body 14 during the movement, further improving the image acquisition quality of the solution.

[0023] It should be noted that since the cable 14 passes through the upper part of the cylinder 1, and the positioning frame 11 is located at the bottom inside the cylinder 1, while the power mechanism and the traveling components are concentrated in the middle and lower part of the cylinder 1, the overall center of gravity of the device is lower, and the device itself has good static stability. When the device is affected by external wind force and tends to tilt during operation, its own weight will generate a restoring torque, forcing the device to return to the initial stable equilibrium state, thereby effectively suppressing the device's tilt and rotation, improving the stability of image acquisition operations, and effectively ensuring the information acquisition quality of the solution.

[0024] On the other hand, by using its own vertically downward gravity, the device continuously and automatically returns to its initial vertical attitude, effectively reducing the reliance on complex active control systems, improving operational robustness, and thus achieving passive stabilization. It does not require additional auxiliary motors or gyroscopes to stabilize itself, effectively saving energy and improving the efficiency of the solution.

[0025] At the same time, due to the influence of the device's own weight, when it is sleeved on the outside of the cable body 14, the effect of the device's own weight will cause the cable body 14 inside the cylinder 1 to be straightened and tightened, thereby opening up the micro-cracks that were originally closed due to sag, thus exposing the damage and effectively reducing the error of image acquisition.

[0026] Example 2: Please see Figure 2 and Figure 3This embodiment further illustrates the following based on Embodiment 1: The power mechanism includes a drive shaft 2 that is rotatably connected to the end of the positioning frame 11 away from the inner wall of the cylinder 1. A motor 21 is fixedly connected to the end of the drive shaft 2 pointing towards the inside of the cylinder 1. A spur gear 22 is fixedly connected to the end of the drive shaft 2 pointing towards the end of the cylinder 1. An internal gear ring 23 is meshed and driven on the outer contour of the spur gear 22. A turntable 24 is fixedly connected to the side of the internal gear ring 23 away from the motor 21. A monitoring module 25 is fixedly connected to the outer edge of the turntable 24 away from the internal gear ring 23. A cable 14 passes through and rotatably connects to the center of the turntable 24.

[0027] First, after assembling and fitting the device onto the outer surface of the cable body 14, the motor 21 is started and the device begins to work. At this time, the motor 21 drives the spur gear 22 to rotate synchronously through the drive shaft 2. The spur gear 22 further drives the internal gear ring 23 and the turntable 24 to rotate synchronously. Since the cable body 14 passes through the center of the turntable 24, that is, the turntable 24 revolves around the cable body 14. The monitoring module 25 revolves synchronously around the turntable 24. During the revolution of the monitoring module 25, the distance between it and the cable body 14 remains fixed, thereby achieving a fixed-distance circumferential monitoring effect on the outer surface of the cable body 14.

[0028] Example 3: Please see Figures 4 to 6 This embodiment further illustrates the following based on Embodiment 2: The cylindrical cam 3 is fixedly connected to the side of the turntable 24 away from the monitoring module 25. The end of the cylindrical cam 3 away from the turntable 24 is fixedly connected to the turntable 31. The turntable 31 away from the cylindrical cam 3 has a guide groove 32. A transmission pin 33 is engaged on the outer contour of the cylindrical cam 3. A transmission rod 34 is fixedly connected to the bottom end of the pin 33. A transmission pin 35 is engaged on the inner contour of the guide groove 32. A connecting rod 36 is fixedly connected to the outer contour of the transmission pin 35.

[0029] The telescopic mechanism also includes a fixed cylinder 4 fixedly connected to the end of the connecting rod 36 away from the transmission pin 35. A spline rod 41 is penetrated inside the fixed cylinder 4. The fixed cylinder 4 and the spline rod 41 are connected by a spline engagement. A positioning ring 42 is fixedly connected to the outer contour of the spline rod 41 away from the connecting rod 36. A connecting plate 43 is connected to the outer contour of the positioning ring 42. The end of the connecting plate 43 away from the positioning ring 42 is fixedly connected to the end of the transmission rod 34 away from the pin 33.

[0030] Furthermore, as turntable 24 rotates, it drives cylindrical cam 3, turntable 2 31 and guide groove 32 to rotate synchronously. At this time, cylindrical cam 3 tends to drive pin 33 to rotate synchronously, and turntable 2 31 and guide groove 32 tend to drive transmission pin 35 to rotate synchronously.

[0031] It should be noted that the transmission pin 35 is connected to the fixed cylinder 4 via the connecting rod 36, and the pin 33 is connected to the spline rod 41 via the transmission rod 34 and the connecting plate 43. However, the fixed cylinder 4 is limited by the clamping mechanism and cannot revolve around the cable body 14. The spline rod 41 and the fixed cylinder 4 are synchronously restricted. Therefore, neither the pin 33 nor the transmission pin 35 can rotate synchronously with the cylindrical cam 3 and the guide groove 32.

[0032] like Figure 4 and Figure 5 As shown, the rotation of the cylindrical cam 3 causes the pin 33 to move horizontally along the groove on its surface. When the cylindrical cam 3 rotates once, the pin 33 reciprocates horizontally once. The transmission rod 34 and the connecting plate 43 move in the same direction as the pin 33. While the connecting plate 43 moves horizontally, it pulls the spline rod 41 to move synchronously through the positioning ring 42. The fixed cylinder 4 remains fixed due to the limitation of the clamping mechanism. Therefore, every time the cylindrical cam 3 rotates once, the spline rod 41 extends and retracts from the inside of the fixed cylinder 4 once. The automatic reciprocating extension and retraction effect of the spline rod 41 is achieved by the continuous unidirectional rotation of the cylindrical cam 3.

[0033] On the other hand, the trajectory of the guide groove 32 can be divided into a large circular arc segment, a small circular arc segment, and two straight segments connecting the large and small circular arc segments. In the initial state, the transmission pin 35 is located in the large circular arc segment. As the guide groove 32 rotates, the contact position of the transmission pin 35 in the guide groove 32 changes as follows: large circular arc segment - straight segment - small circular arc segment - straight segment 2 - large circular arc segment, and so on in a cycle.

[0034] like Figure 5 and Figure 6 As shown, since the center distances of the large and small arc segments are inconsistent, and the fixed cylinder 4 is located in the middle position between the extended circles of the large and small arc segments, when the guide groove 32 rotates and the transmission pin 35 passes through the corner position of the large arc segment, the transmission pin 35 will be displaced. At this time, the connecting rod 36 will swing 90 degrees with the fixed cylinder 4 as the center. The fixed cylinder 4 and the spline rod 41 will rotate 90 degrees synchronously through spline engagement, and the rotation directions at the two corner positions are opposite. That is, for every rotation of the guide groove 32, the fixed cylinder 4 and the spline rod 41 will reciprocate twice by 90 degrees. Through the continuous unidirectional rotation of the guide groove 32, the fixed cylinder 4 and the spline rod 41 will automatically reciprocate, and the rotation angle will be fixed at 90 degrees.

[0035] In summary, when turntable 1 24 drives cylindrical cam 3, turntable 2 31 and guide groove 32 to rotate synchronously, spline rod 41 achieves automatic reciprocating extension and retraction from inside fixed cylinder 4, while fixed cylinder 4 and spline rod 41 achieve automatic reciprocating rotation.

[0036] Example 4: Please see Figures 7 to 9This embodiment further illustrates the following based on Embodiment 3: The inner contour of one end of the transmission belt 5 is frictionally connected to the outer contour of the fixed cylinder 4 near the connecting rod 36. The inner contour of the other end of the transmission belt 5 is frictionally connected to a pulley 51. A threaded ring 52 is fixedly connected to the side of the pulley 51 away from the turntable 31. Multiple equally spaced locking blocks 53 are connected to the outer contour of the threaded ring 52. A fixed seat 54 is provided on the side of the threaded ring 52 away from the pulley 51. Multiple equally spaced limiting grooves 55 are opened on the surface of the fixed seat 54 pointing towards the threaded ring 52. A fixed rod 56 is fixedly connected to the outer contour of the fixed seat 54. The fixed rod 56 is fixedly connected to the inner wall of the cylinder 1.

[0037] The pulley 51, the threaded ring 52, and the fixing seat 54 are all penetrated by the cable body 14 and sleeved on the outer contour of the cable body 14. The multiple locking blocks 53 and the limiting grooves 55 are correspondingly adapted and slidably connected.

[0038] The inner contour of one end of the transmission belt 6 is frictionally connected to the outer contour of the spline rod 41 away from the connecting rod 36. The inner contour of the other end of the transmission belt 6 is frictionally connected to the pulley 61. The pulley 61 is fixedly connected to the side away from the fixed seat 54 with a threaded ring 62. The outer contour of the threaded ring 62 is connected to multiple equally spaced and circumferentially distributed locking blocks 63. The side of the threaded ring 62 away from the pulley 61 is provided with a positioning seat 64. The surface of the positioning seat 64 pointing towards the threaded ring 62 is provided with multiple equally spaced and circumferentially distributed limiting grooves 65. The outer contour of the positioning seat 64 is fixedly connected to a sliding rod 66, which is slidably connected to the interior of the corresponding position groove 13.

[0039] The second pulley 61, the second threaded ring 62, and the positioning seat 64 are all penetrated by the cable body 14 and sleeved on the outer contour of the cable body 14. The multiple second locking blocks 63 are correspondingly adapted to and slidably connected with the second limiting groove 65. The second threaded ring 62 and the first threaded ring 52 have opposite rotation directions. The sliding rod 66 is limited and rotatably connected to the end of the spline rod 41 away from the fixed cylinder 4.

[0040] Furthermore, since the fixed cylinder 4 is connected to the pulley 51 via the transmission belt 5, and the spline rod 41 is connected to the pulley 61 via the transmission belt 6, the movement of the pulley 51 and the pulley 61 is consistent with that of the fixed cylinder 4 and the spline rod 41. When the fixed cylinder 4 and the spline rod 41 reciprocate, the pulley 51 and the pulley 61 reciprocate synchronously. When the spline rod 41 reciprocates from the inside of the fixed cylinder 4, the pulley 61 reciprocates horizontally on the outer surface of the cable body 14.

[0041] Therefore, the rotation of pulley 51 drives the threaded ring 52 to rotate synchronously. The rotation of the threaded ring 52 further causes the locking block 53 to tend to rotate synchronously. However, since the fixing rod 56 is fixedly connected to the inner wall of the cylinder 1, the fixing seat 54 and the limiting groove 55 cannot rotate. The locking block 53 is slidably connected in the limiting groove 55, so the locking block 53 also cannot rotate. At this time, the rotation of the threaded ring 52 will cause the locking block 53 to contract inward, thereby increasing the pressure of the locking block 53 on the outer surface of the cable body 14. This increases the static friction between the locking block 53 and the cable body 14, thus making the locking block 53 lock the cable body 14.

[0042] At the same time, the rotation of pulley 2 61 drives threaded ring 2 62 to rotate synchronously, and locking block 2 63 also tends to rotate. However, the cooperation between the sliding groove 13 and the sliding rod 66 prevents locking block 2 63 from rotating synchronously. Since the rotation direction of threaded ring 2 62 is opposite to that of threaded ring 1 52, the rotation of threaded ring 2 62 will cause locking block 2 63 to expand outward, thereby reducing the pressure of locking block 2 63 on the outer surface of cable body 14, so as to reduce the static friction between locking block 2 63 and cable body 14.

[0043] Furthermore, after the second locking block 63 expands outward, the rotation of the cylindrical cam 3 causes the spline rod 41 to extend synchronously from the inside of the fixed cylinder 4. The spline rod 41 synchronously drives the sliding rod 66 to slide within the slide groove 13, as... Figure 8 As shown, when the spline rod 41 extends, the sliding rod 66 slides from the left side to the right side in the slide groove 13. During this process, the positioning seat 64, the second locking block 63, the second threaded ring 62, the second pulley 61, and the second transmission belt 6 all move synchronously. The second pulley 61 slides horizontally to the right synchronously on the outer surface of the cable body 14.

[0044] Subsequently, the further rotation of the guide groove 32 causes the fixed cylinder 4 and the spline rod 41 to rotate 90 degrees in the opposite direction. At this time, the pulley 51 and the pulley 61 rotate 90 degrees in the opposite direction synchronously. Therefore, the movement of the locking block 53 and the locking block 63 is the opposite of the previous movement. At this time, the locking block 53 expands outward to release the clamping of the cable body 14, and the locking block 63 retracts inward to clamp the cable body 14.

[0045] Furthermore, the further rotation of the cylindrical cam 3 causes the spline rod 41 to begin to retract. However, because the second clamping block 63 clamps the cable body 14, the sliding rod 66 cannot retract synchronously with the spline rod 41. The position of this clamping mechanism on the outer surface of the cable body 14 is fixed, which in turn causes the fixed cylinder 4 to drive the telescopic mechanism, the power mechanism, and the cylinder 1 as a whole to slide to the right on the surface of the cable body 14, so that the spline rod 41 retracts smoothly into the interior of the fixed cylinder 4.

[0046] In summary, during the peristaltic movement of the device, the position of the fixed cylinder 4 and the cylinder 1 is fixed because the first clamp 53 clamps the cable 14. At this time, the contact between the second clamp 63 and the cable 14 is in a relaxed state. Then, the spline rod 41 drives the second clamp 63 to extend to the right. After extending to the limit distance, the second clamp 63 clamps the cable 14 while the first clamp 53 is released. At this time, the position of the spline rod 41 is fixed, and the fixing effect of the fixed cylinder 4 and the cylinder 1 is released. Afterward, the spline rod 41 begins to retract, causing the fixed cylinder 4 and the cylinder 1 to slide to the right. The intermittent rightward sliding of the cylinder 1 realizes the peristaltic movement of the device.

[0047] Compared to traditional wheeled travel, the creeping travel method offers higher reliability and stability. Especially under rain, snow, or icy conditions, wheeled travel may slip due to insufficient friction with the cable surface, leading to inaccurate positioning, displacement errors, or even loss of control and a fall. In contrast, the creeping travel method uses intermittent clamping, with either clamp 53 or clamp 63 providing significant static friction during movement, fundamentally preventing slippage. At any given moment during travel, at least one of clamps 53 or 63 firmly grips the cable, and the displacement at each step is known and fixed, resulting in more precise positioning and significantly reducing the risk of accidental detachment.

[0048] It should be noted that, since the cable 14 always passes through the guide groove 32 during the movement, the guide groove 32 and the outer surface of the cable 14 always maintain contact. By setting a friction pad at the point where the cable 14 passes through the guide groove 32, impurities adhering to the surface of the cable 14 can be effectively removed by scraping during the movement of the device, thereby further ensuring the image acquisition quality of the monitoring module 25.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
