Description

Technical Field

[0001] This invention relates to the field of monitoring equipment technology, and in particular to a device for monitoring the thickness of cable icing due to freezing rain. Background Technology

[0002] Monitoring cable icing thickness is a crucial aspect of power system maintenance, especially in cold and humid environments. Icing increases cable weight, potentially leading to cable breakage, tower collapse, and other accidents, severely impacting the safety and stability of power transmission. Therefore, real-time monitoring of icing thickness is essential.

[0003] Currently, the equipment available on the market for monitoring cable icing thickness mainly falls into two categories:

[0004] 1. Cut-off observation type: This type of equipment is usually installed on power towers, and a sample cable of the same specifications as the actual cable is connected to the testing device. Although this method provides relatively intuitive monitoring data, because the installation location is close to the power tower, it may block some rain and snow from falling on the sample cable. As a result, the icing condition on the sample cable may not fully represent the actual icing condition of the cable on the power tower, thus affecting the accuracy of the monitoring results.

[0005] 2. Direct Cable Installation Type: This type of monitoring equipment (e.g., transmission line icing thickness sensors) is directly installed on the cables of the power tower. Due to the long spans of these cables, accurate assessment of icing conditions across the entire span often requires powerful computing capabilities and intelligent algorithms to process and analyze data collected from multiple sensors. Furthermore, the installation process for this type of equipment carries certain risks, as it must be attached to cables far from the edge of the power tower. Moreover, these monitoring devices rely solely on their own sensor performance for icing monitoring, making them susceptible to damage from environmental factors, thus affecting the reliability of the data. Summary of the Invention

[0006] The purpose of this invention is to provide an adjustable, portable device for monitoring the thickness of cable freezing rain and icing in order to solve the above-mentioned problems.

[0007] This invention achieves the above-mentioned objective through the following technical solution: A device for monitoring the thickness of freezing rain icing on cables, comprising a micro-meteorological acquisition unit and an image acquisition unit, and further comprising a clamping plate, the clamping plate being provided with a clamping assembly for clamping and fixing it to the crossarm of a power tower, a guide rail being connected to the top of the clamping plate, a slider being slidably provided outside the guide rail, and a bolt being provided on the slider for locking it to the guide rail, the micro-meteorological acquisition unit being installed on the top of the slider for collecting meteorological parameter data, and a carriage being slidably provided inside the guide rail, within which two front and rear weighing sensors located outside the guide rail are installed.

There are two nuts one in each set, and the two nuts one in each set are set one in front and one behind. A mounting plate is connected to the right side of the clamping plate. Both the front and rear sides of the mounting plate are connected to screws one, and two nuts two for locking the sliding sleeve four are threaded on the screws one.

[0009] Preferably, the clamp includes a fixed clamping block connected to the bottom of the connecting plate, a movable clamping block hinged to the fixed clamping block, both the fixed clamping block and the movable clamping block being arc-shaped, the fixed clamping block and the movable clamping block being locked together by bolts, semi-circular rubber blocks being connected to the front and rear sides of both the fixed clamping block and the movable clamping block, telescopic clamping blocks being connected circumferentially at intervals on the inner walls of both the fixed clamping block and the movable clamping block, each telescopic clamping block being provided with a spring, and heating elements being installed at intervals between two adjacent telescopic clamping blocks on the fixed clamping block and between two adjacent telescopic clamping blocks on the movable clamping block.

[0010] Preferably, a transparent plate is connected to the left side of the connection shell for sealing the connection shell. A heating plate located inside the connection shell is installed on the transparent plate. The heating plate is in a shape of a square frame with a hole in the middle for heating the transparent plate.

[0011] Preferably, a heating rod is connected to the carriage and located outside the first guide rail. The left end of the heating rod is connected to a measuring rod facing the image acquisition unit. Scale lines are engraved on the measuring rod for measuring the ice thickness on the sample cable.

[0012] Preferably, a stabilizing mechanism is provided at the bottom of the sliding plate. The stabilizing mechanism includes a screw rod three rotatably connected to the bottom of the sliding plate. A threaded block is threadedly connected to the screw rod three. A slide rail is connected to the bottom of the threaded block.

[0017] 2. Moving the slide to the left will move the sample cable away from the power tower, preventing it from being blocked by the tower and affecting the rain and snow falling on it. This makes the icing condition on the sample cable closer to the actual icing condition of the power transmission cable on the tower, thus improving the accuracy of the monitoring results. The weighing sensor can detect the weight change of the sample cable after icing in real time, thereby improving the accuracy and timeliness of icing monitoring.

[0018] 3. By using the fixed arc-shaped clamps and movable arc-shaped clamps on the front and rear sides of the stabilizing mechanism, the entire stabilizing mechanism can be clamped and fixed to the two adjacent transmission lines, thereby providing stable support for the entire device and improving the stability of the device installation.

Detailed Implementation

[0030] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] See Figures 1-7A device for monitoring the thickness of freezing rain icing on cables includes a clamping plate 3. The clamping plate 3 is equipped with a clamping assembly 4 for clamping and fixing it to a crossarm 25 of a power tower. The bottom of the clamping plate 3 is arc-shaped to better fit the cylindrical crossarm 25. A guide rail 5 is connected to the top of the clamping plate 3. A reinforcing rib 32 is connected between the bottom of the guide rail 5 and the left side of the clamping plate 3. The clamping plate 3, the guide rail 5, and the reinforcing rib 32 form a stable triangular structure to improve the stability and strength of the overall structure. A slider 6 is slidably mounted on the outside of the guide rail 5. Two bolts 61 are symmetrically mounted on both the front and rear sides of the slider 6 to lock the slider 6 onto the guide rail 5. The top of the slider 6... A micro-meteorological acquisition unit 1 is installed to collect meteorological parameter data for monitoring local meteorological conditions. The micro-meteorological acquisition unit 1 is existing technology and will not be described in detail here. A sliding carriage 7 is installed inside the guide rail 5. The carriage 7 includes a horizontal plate 71 slidably installed inside the guide rail 5. A U-shaped plate 72 located outside the guide rail 5 is connected to the left end of the horizontal plate 71.

The wiring of the device 8 is shielded and protected to cover the wiring of the weighing sensor 8. A blocking block 51 is connected to the left side of the bottom surface of the guide rail 1 5. The blocking block 51 is located in the wire groove 74 of the horizontal plate 71 and is used to block and position the horizontal plate 71 to prevent the horizontal plate 71 from sliding directly out of the guide rail 1 5 and completely detaching from the guide rail 1 5. J-shaped connecting plates 9 are connected to both weighing sensors 8. The bottom of the connecting plates 9 penetrates the bottom of the mounting shell 73. The bottom of both connecting plates 9 is provided with clamps 10 for clamping and fixing the sample cable 23. The bottom of the guide rail 1 5 is connected to the guide rail 2 11 located to the left of the reinforcing rib 32. A sliding plate 12 is slidably provided in the guide rail 2 11. The sliding plate 12 is provided with a tool for locking it. Bolt 13 is on guide rail 11. Slider 14 is slidably mounted on slide plate 12. Slider 14 is connected to a connecting shell 15 with an open left side. An image acquisition unit 2 is installed inside the connecting shell 15 to capture images of ice on the sample cable 23, so as to monitor the ice thickness of the sample cable 23. The image acquisition unit 2 is existing technology and will not be described in detail here. L-shaped plugs 16 are connected to the lower part of the front, left and rear sides of slide plate 12. Slider 14 has a socket 17 on the front, left and rear sides that matches the L-shaped plug 16. Slider 14 is locked to the L-shaped plug 16 through the socket 17 to prevent slider 14 from slipping off slide plate 12.

[0032] See Figures 4-6The clamping assembly 4 includes two screw rods 46 connected to the lower front and rear sides of the clamping plate 3, respectively. Each screw rod 46 has a sliding sleeve 48 slidably fitted onto it. Two nuts 47 for locking the sliding sleeves 48 are threaded onto each screw rod 46. Threaded rods 49 are rotatably connected to the outside of each sliding sleeve 48. Threaded sleeves 410 are threaded onto each threaded rod 49. Sliding sleeves 411 are connected to the ends of each threaded sleeve 410 away from the screw rod 46 on the same side. A clamping rod 412 is slidably connected between the two sliding sleeves 411. Two sliding sleeves 413 are slidably connected to the clamping rod 412, located between the two sliding sleeves 411. Each sliding sleeve 3 413 is externally connected to a threaded sleeve 2 416. Each of the two threaded sleeves 2 416 is internally threaded with a threaded rod 2 415. The top of each of the two threaded rods 2 415 is rotatably connected to a sliding sleeve 414. The clamping plate 3 has a vertical groove 31. A double-acting screw 41 is slidably installed in the vertical groove 31. The double-acting screw 41 is threaded with two sets of nuts 1 42 for locking the sliding sleeve 414. Each set of nuts 1 42 has two nuts, which are arranged one in front and one behind. The right side of the clamping plate 3 is connected to a mounting plate 43. Both the front and rear sides of the mounting plate 43 are connected to screws 1 44. Each screw 1 44 is threaded with two nuts 2 45 for locking the sliding sleeve 414.

[0033] See Figures 7-9 The clamp 10 includes a fixed clamping block 101 connected to the bottom of the connecting plate 9. A movable clamping block 102 is hinged to the top of the fixed clamping block 101. Both the fixed clamping block 101 and the movable clamping block 102 are arc-shaped and are locked together by bolts 103. Semi-circular rubber blocks 104 are connected to the front and rear sides of both the fixed clamping block 101 and the movable clamping block 102. Three telescopic clamping blocks 105 are connected circumferentially at intervals on the inner walls of both the fixed clamping block 101 and the movable clamping block 102. Each telescopic clamping block... Each of the 105 is equipped with a spring 106. The two ends of the spring 106 are connected to the fixed end and the movable end of the telescopic clamp 105, respectively. Three heating elements 107 are installed between two adjacent telescopic clamps 105 on the fixed clamp 101 and between two adjacent telescopic clamps 105 on the movable clamp 102, spaced from front to back. The heating elements 107 are connected to the fixed end of the telescopic clamp 105. The telescopic clamp 105 is made of metal. The metal telescopic clamp 105 has good thermal conductivity and can effectively conduct heat.

[0034] To fix this device to the cylindrical crossarm 25 on the power tower, first place the clamping plate 3 on the upper side of the cylindrical crossarm 25. Then, put the two sliding sleeves 414 onto the two screws 44 respectively. Next, insert the clamping rod 412 into the two sliding sleeves 413. Then, rotate the threaded rod 415 to push the threaded sleeve 416 upward, thereby pulling the clamping rod 412 upward through the sliding sleeves 413 to fit tightly against the cylindrical crossarm 25. Then push the two threaded sleeves 416 closer together to fit tightly against the cylindrical crossarm 25. Then, lock the sliding sleeves 414 with the two nuts 45 on the screws 44, thereby locking the threaded rod 415, the threaded sleeve 416, the sliding sleeves 413, and the clamping rod 412. Through the cooperation of the clamping plate 3, the threaded sleeve 416, and the clamping rod 412, the entire device can be locked onto the cylindrical crossarm 25 of the power tower. Then, with one hand holding the threaded rod 49, the other hand rotates the threaded sleeve 410 to move it on the threaded rod 49, adjusting the distance between the sliding sleeve 48 and the second sliding sleeve 411, so that the sliding sleeve 48 is aligned with the screw 46 and the second sliding sleeve 411 is aligned with the clamping rod 412. Then, the second sliding sleeve 411 is put on the clamping rod 412, and the first sliding sleeve 48 is put on the screw 46. Finally, the two nuts 47 on the screw 46 are used to lock the first sliding sleeve 48, thereby further locking the clamping plate 3, the threaded sleeve 416 and the clamping rod 412, and firmly locking the entire device on the cylindrical crossarm 25 of the power tower.

[0035] To fix this device to the L-shaped crossarm 25 on the power tower, first place the clamping plate 3 on the left side of the L-shaped crossarm 25, then put the two sliding sleeves 414 on the front and rear sides of the double-acting screw 41 respectively, and the threaded sleeve 416 presses down on the upper side of the L-shaped crossarm 25. Then insert the clamping rod 412 into the two sliding sleeves 413, and then reverse the threaded rod 415 to push the threaded sleeve 416 down, thereby pushing the clamping rod 412 down to be flush with the bottom of the L-shaped crossarm 25 through the sliding sleeves 413. Then, holding the threaded rod 49 in one hand, rotate the threaded sleeve 410 in the other hand to move it on the threaded rod 49, adjusting the distance between the sliding sleeve 48 and the second sliding sleeve 411. This aligns the sliding sleeve 48 with the screw 46 and the sliding sleeve 411 with the clamping rod 412. Then, the second sliding sleeve 411 is placed on the clamping rod 412, and the first sliding sleeve 48 is subsequently placed on the screw 46, so that the threaded sleeve 410... The screw 48 is tightly attached to the bottom of the L-shaped crossarm 25. Then, the two nuts 47 on the screw 46 lock the sliding sleeve 48. Finally, the nut 42 on the double-acting screw 41 locks the sliding sleeve 414, thus locking the clamping plate 3, threaded sleeve 410, threaded sleeve 416, and clamping rod 412. Through the cooperation of the clamping plate 3, threaded sleeve 410, and threaded sleeve 416, the entire device can be locked onto the L-shaped crossarm 25 of the power tower. Therefore, this device, through the cooperation of the clamping plate 3 and the threaded clamping assembly 4, achieves an adjustable and portable installation method, adaptable to crossarms 25 of different shapes and specifications on power towers, ensuring versatility on different types of power towers, providing a convenient installation method, enhancing stability, improving flexibility and safety.

[0036] After the entire device is locked onto the crossarm 25 of the power tower, slider 16 is installed on guide rail 15 and locked with bolt 161. Then, slide plate 12 is installed on guide rail 21 and locked with bolt 213. Subsequently, slider 24 is installed on slide plate 12 and inserted into L-shaped plug 16 through socket 17 to lock slider 24. Next, sample cable 23 is placed into fixed clamp 101 and movable clamp 102, and fixed clamp 101 and movable clamp 102 are locked together with bolt 3103. Sample cable 23 is then aligned with image acquisition unit 2. Spring 106 allows the movable end of telescopic clamp 105 to be tightly pressed against sample cable 23 to clamp and fix sample cable 23, accommodating sample cables 23 of different diameters. Finally, the slide 7 is moved to the left, thereby moving the sample cable 23 away from the power tower to the left, preventing the sample cable 23 from being blocked by the power tower and affecting the rain and snow falling on the sample cable 23. This makes the icing condition on the sample cable 23 closer to the actual icing condition of the transmission cable 24 on the power tower, thereby improving the accuracy of the monitoring results.

[0037] The micro-meteorological acquisition unit 1 collects meteorological parameter data and transmits it to the backend via the network to monitor local meteorological conditions. The image acquisition unit 2 captures images of icing on the sample cable 23 and transmits them to the backend via the network to monitor the thickness of the icing on the sample cable 23. The weighing sensor 8 detects the weight change of the sample cable 23 after icing in real time and transmits the data to the backend via the network to improve the accuracy and timeliness of icing monitoring. When it is necessary to remove the icing on the sample cable 23, the heating element 107 is controlled to heat the telescopic clamp 105. The telescopic clamp 105 conducts heat to the sample cable 23, melting the icing and removing it. The rubber block 104 seals the fixed clamp 101 and the movable clamp 102 to prevent rain and snow from entering them, thus protecting the heating element 107.

[0038] See Figure 3 A transparent plate 151 is connected to the left side of the connecting shell 15. A heating plate 152 located inside the connecting shell 15 is installed on the transparent plate 151. The heating plate 152 is shaped like a U-shape. The transparent plate 151 can seal the connecting shell 15, protecting the image acquisition unit 2 inside the connecting shell 15 from damage caused by rain and snow. The heating plate 152 can heat the transparent plate 151 and the camera of the image acquisition unit 2, effectively preventing the formation of fog in cold weather and ensuring the clarity of image acquisition.

[0039] See Figure 7 and Figure 10The bottom of the slide plate 12 is equipped with a stabilizing mechanism, which includes a screw 181 rotatably connected to the bottom of the slide plate 12. A threaded block 182 is threaded onto the screw 181, and a slide rail 183 is connected to the bottom of the threaded block 182. Two sliding plates 184 are slidably connected inside the slide rail 183, and the two sliding plates 184 are arranged vertically. Each sliding plate 184 includes a horizontal section and an arc-shaped section. The arc-shaped section of the sliding plate 184 is located outside the slide rail 183. A fixed arc-shaped clamp 185 is connected to the arc-shaped section of the sliding plate 184. A movable arc-shaped clamp 186 is hinged to the right side of the fixed arc-shaped clamp 185. A bolt 187 is provided on the movable arc-shaped clamp 186. An opening is provided at the arc-shaped section of the sliding plate 184 for screws. The sliding rail 183 has a sliding arc-shaped groove for sliding four 187. A drive assembly is provided on the slide rail 183 to drive the two sliding plates 184 to move closer and further apart. The drive assembly includes an outer diamond-shaped rod 188 rotatably connected to the right side wall of the slide rail 183. A gear 189 located inside the slide rail 183 is connected to the outer diamond-shaped rod 188. An inner diamond-shaped threaded sleeve 1810 located to the right of the slide rail 183 is slidably sleeved on the outer diamond-shaped rod 188. An inner threaded sleeve 1811 is threadedly connected to the outer side of the inner diamond-shaped threaded sleeve 1810. The inner threaded sleeve 1811 is fixedly connected to the outer right side wall of the slide rail 183. A rack 1812 is connected to the horizontal section of each of the two sliding plates 184. The rack 1812 meshes with the gear 189.

[0040] First, based on the spacing between two adjacent transmission cables 24 on the power tower, adjust the distance between the fixed arc-shaped clamps 185 and the movable arc-shaped clamps 186 on both sides. Rotate the inner diamond-shaped threaded sleeve 1810 to drive the outer diamond-shaped rod 188 to rotate. The rotation of the outer diamond-shaped rod 188 drives the gear 189 to rotate. The rotation of the gear 189 pushes the two racks 1812 to move in opposite directions, thereby driving the two sliding plates 184 to move in opposite directions, thus making the fixed arc-shaped clamps 185 and the movable arc-shaped clamps 186 on both sides move away from each other. Similarly, reversing the inner diamond-shaped threaded sleeve 1810 can make the fixed arc-shaped clamps 185 and the movable arc-shaped clamps 186 on both sides move closer to each other. When the inner diamond-shaped threaded sleeve 1810 rotates, it slides on the outer diamond-shaped rod 188 and within the inner threaded sleeve 1811. The inner diamond-shaped threaded sleeve 1810 is locked by the inner threaded sleeve 1811, thereby locking the outer diamond-shaped rod 188, gear 189, rack 1812, and sliding plate 184 to prevent the fixed arc-shaped clamp 185 and the movable arc-shaped clamp 186 from moving back and forth on their own. Next, the fixed arc-shaped clamps 185 and the movable arc-shaped clamp 186 on the front and rear sides are respectively placed on the two adjacent transmission cables 24. Then, the movable arc-shaped clamp 186 is rotated towards the transmission cable 24 on the same side. Subsequently, the bolts 187 are tightened to lock the movable arc-shaped clamp 186 onto the sliding plate 184. The fixed arc-shaped clamps 185 and the movable arc-shaped clamp 186 are clamped and fixed on the transmission cable 24 through the cooperation of the fixed arc-shaped clamps 185 and the movable arc-shaped clamp 186. Then, screw 181 is turned into threaded block 182 to connect slide plate 12 and slide rail 183 together. Finally, clamping assembly 4 is used to lock clamping plate 3 onto crossarm 25 of power tower. By clamping and fixing the stabilizing mechanism to two adjacent transmission lines, stable support can be provided for the entire device, thereby improving the stability of the device installation.

[0041] See Figure 7 A heating rod 21 is connected inside the U-shaped plate 72 of the carriage 7. The left end of the heating rod 21 is connected to a measuring rod 22 facing the image acquisition unit 2. The measuring rod 22 has scale lines engraved on it, which can measure the ice thickness on the sample cable 23. The heating rod 21 can heat the measuring rod 22 to prevent the measuring rod 22 from freezing in cold weather and prevent the scale lines from being covered by ice and snow, thereby ensuring the accuracy of the ice thickness measurement.

[0042] See Figure 1 and Figure 10 The top of the upper sliding plate 184 is connected by bolts to a connecting block 19 located outside the slide rail 183. The connecting block 19 is in the shape of an inverted U. The left side of the inverted U-shaped connecting block 19 is bolted to a CT power supply device 20. The CT power supply device 20 is electrically connected to the micro-meteorological acquisition unit 1, the image acquisition unit 2, the weighing sensor 8, the heating element 107, the heating plate 152, and the heating rod 21.

[0043] The CT power harvesting device 20 is mounted on the power transmission cable 24 of the power tower. When current flows through the CT power harvesting device 20, it generates electrical energy to power the micro-meteorological acquisition unit 1, image acquisition unit 2, weighing sensor 8, heating element 107, heating plate 152, and heating rod 21. CT power harvesting technology is a mature existing technology and will not be elaborated further here. Compared to the existing technology that uses photovoltaic panels for power supply, the CT power harvesting device 20 can provide a more stable and reliable power supply, unaffected by weather conditions. This ensures that the equipment can continue to operate normally even under adverse weather conditions such as cloudy or overcast skies, thereby improving the operational stability of the entire system and the reliability of data acquisition.
