Description

Technical Field

[0001] The present invention relates to the technical field of monitoring devices, and particularly to a device for monitoring the ice thickness on cables caused by freezing rain. Background Art

[0002] Monitoring the ice thickness on cables caused by freezing rain is an important aspect in the maintenance of power systems, especially in cold and humid environments. Ice accretion increases the weight of the cables, which may lead to accidents such as cable breakage and pole collapse, seriously affecting the safety and stability of power transmission. Therefore, it is crucial to monitor the ice thickness in real time.

[0003] Currently, the devices used for monitoring the ice thickness on cables in the market are mainly divided into two categories:

[0004] 1. Truncation and observation type: Such devices are usually installed on power towers. A sample cable with the same specifications as the actual cable is connected to the detection device. Although the monitoring data provided by this method is relatively intuitive, since the installation position is close to the power tower, it may block some rain and snow from falling on the sample cable, resulting in the icing condition on the sample cable not being able to fully represent the true icing condition of the actual cable on the power tower, thus affecting the accuracy of the monitoring results.

[0005] 2. Direct cable installation type: Such monitoring devices (such as ice thickness sensors for transmission lines) are directly installed on the cables of power towers. Due to the long span of the cables, in order to accurately evaluate the icing condition within the entire span, powerful computing capabilities and intelligent algorithms are often required to process and analyze the data collected from multiple sensors. In addition, the installation process of such devices has a certain risk because they must be attached to the cables far from the edge of the power tower. Moreover, these monitoring devices rely only on their own sensor performance for ice accretion monitoring and are easily damaged by environmental factors, thus affecting the reliability of the data. Summary of the Invention

[0006] The purpose of the present invention is to provide a device for monitoring the ice thickness on cables caused by freezing rain that can be adjusted and is portable for installation in order to solve the above problems.

The number of each group of first nuts 42 is two. The two first nuts 42 in each group are arranged front and back. An installation plate 43 is connected to the right side of the clamping plate 3. A first screw 44 is connected to the front and rear sides of the installation plate 43. Two second nuts 45 for locking the fourth sliding sleeve 414 are threadedly connected to the first screw 44.

[0033] See Figures 7 - 9 , the fixture 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. The fixed clamping block 101 and the movable clamping block 102 are locked together by a third bolt 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 circumferentially and spacedly connected to the inner walls of both the fixed clamping block 101 and the movable clamping block 102. A spring 106 is arranged in each of the telescopic clamping blocks 105. The two ends of the spring 106 are respectively connected to the fixed end and the movable end of the telescopic clamping block 105. Three heating sheets 107 are installed at intervals from front to back between two adjacent telescopic clamping blocks 105 on the fixed clamping block 101 and between two adjacent telescopic clamping blocks 105 on the movable clamping block 102. The heating sheet 107 is connected to the fixed end of the telescopic clamping block 105. The telescopic clamping block 105 is made of a metal material. The metal telescopic clamping block 105 has good heat conductivity and can effectively conduct heat.

[0034] If the device is to be fixed on the cylindrical cross arm 25 of the power tower, first place the clamping plate 3 on the upper side of the cylindrical cross arm 25. Then, respectively sleeved two sliding sleeves four 414 on the two first screws 44. Next, insert the clamping rod 412 into the two sliding sleeves three 413. Subsequently, rotate the second threaded rod 415 to push the second threaded sleeve 416 upward, so as to pull the clamping rod 412 upward through the sliding sleeve three 413 to be in close contact with the cylindrical cross arm 25. Then, push the two second threaded sleeves 416 closer to each other to be in close contact with the cylindrical cross arm 25. Subsequently, lock the sliding sleeve four 414 through the two second nuts 45 on the first screw 44, thereby locking the second threaded rod 415, the second threaded sleeve 416, the sliding sleeve three 413 and the clamping rod 412. Through the cooperation of the clamping plate 3, the second threaded sleeve 416 and the clamping rod 412, the entire device can be locked on the cylindrical cross arm 25 of the power tower. Subsequently, fix the first threaded rod 49 with one hand and rotate the first threaded sleeve 410 with the other hand, so that the first threaded sleeve 410 moves on the first threaded rod 49 to adjust the distance between the first sliding sleeve 48 and the second sliding sleeve 411, making the first sliding sleeve 48 aligned with the second screw 46 and the second sliding sleeve 411 aligned with the clamping rod 412. Then, sleeve the second sliding sleeve 411 on the clamping rod 412, and the first sliding sleeve 48 will follow and sleeve on the second screw 46. Finally, lock the first sliding sleeve 48 through the two third nuts 47 on the second screw 46, thereby further locking the clamping plate 3, the second threaded sleeve 416 and the clamping rod 412, and firmly locking the entire device on the cylindrical cross arm 25 of the power tower.

[0035] If the device is to be fixed on the L-shaped cross arm 25 on the power tower, first place the clamping plate 3 on the left side of the L-shaped cross arm 25, then respectively put the two sliding sleeves 414 on the front and rear sides of the two-way screw rod 41, and then press the threaded sleeve 2 416 on the upper side of the L-shaped cross arm 25, and then insert the clamping rod 412 into the two sliding sleeves 3 413, and then reverse the threaded rod 2 415 to push the threaded sleeve 2 416 downward, thereby pushing the clamping rod 412 downward through the sliding sleeve 3 413 to be flush with the bottom of the L-shaped cross arm 25. Then, fix the threaded rod 1 49 with one hand and rotate the threaded sleeve 1 410 with the other hand so that the threaded sleeve 1 410 moves on the threaded rod 1 49 to adjust the distance between the sliding sleeve 1 48 and the sliding sleeve 2 411 so that the sliding sleeve 1 48 is aligned with the screw rod 2 46 and the sliding sleeve 2 411 is aligned with the clamping rod 412. Then, the sliding sleeve 2 411 is put on the clamping rod 412, and the sliding sleeve 1 48 is put on the screw rod 2 46 so that the threaded sleeve 1 41 0 is tightly attached to the bottom of the L-shaped cross arm 25, and then the sliding sleeve 1 48 is locked by two nuts 3 47 on the screw rod 2 46, and finally the sliding sleeve 4 414 is locked by the nut 1 42 on the bidirectional screw rod 41, thereby locking the clamping plate 3, the threaded sleeve 1 410, the threaded sleeve 2 416 and the clamping rod 412. Through the cooperation of the clamping plate 3, the threaded sleeve 1 410 and the threaded sleeve 2 416, the entire device can be locked on the L-shaped cross arm 25 of the power tower. Therefore, the device realizes an adjustable and portable installation method through the cooperation of the clamping plate 3 and the threaded clamping assembly 4, can adapt to cross arms 25 of different shapes and specifications on the power tower, ensures the versatility on different types of power towers, provides a convenient installation method, enhances stability, and improves flexibility and safety.

[0036] After the whole device is locked on the cross arm 25 of the power tower, the slider 16 is installed on the guide rail 15 and locked by the bolt 161, and then the slide plate 12 is installed on the guide rail 2 11 and locked by the bolt 2 13, and then the slider 2 14 is installed on the slide plate 12, and the slider 2 14 is inserted into the L-shaped plug rod 16 through the socket 17 to lock the slider 2 14. Then, the sample cable 23 is placed in the fixed clamp block 101 and the movable clamp block 102, and the fixed clamp block 101 and the movable clamp block 102 are locked together by the bolt 3 103, and the sample cable 23 is then aligned with the image acquisition unit 2, and the spring 106 can make the movable end of the telescopic clamp block 105 close to the sample cable 23, so as to clamp and fix the sample cable 23 to adapt to sample cables 23 of different diameters. Finally, the slide 7 is moved to the left, thereby driving the sample cable 23 to the left away from the power tower, avoiding the sample cable 23 being blocked by the power tower and affecting the rain and snow falling on the sample cable 23, so that the icing condition on the sample cable 23 is 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 can collect meteorological parameter data and transmit the meteorological parameter data to the background through the network to realize the monitoring of local meteorological conditions. The image acquisition unit 2 can capture the icing images on the sample cable 23 and transmit the icing images to the background through the network to realize the monitoring of the icing thickness of the sample cable 23. The weighing sensor 8 can detect the weight change of the sample cable 23 after icing in real time and transmit the data to the background through the network to improve the accuracy and timeliness of icing monitoring. When it is necessary to remove the ice on the sample cable 23, the heating sheet 107 is controlled to work to heat the telescopic clamping block 105. The telescopic clamping block 105 conducts heat to the sample cable 23, melting the ice on the sample cable 23 to remove the ice on the sample cable 23. The rubber block 104 can seal the fixed clamping block 101 and the movable clamping block 102 to prevent rain and snow from entering the fixed clamping block 101 and the movable clamping block 102, so as to cover and protect the heating sheet 107.

[0038] See Figure 3 , a transparent plate 151 is connected to the left side of the connection shell 15. A heating plate 152 located inside the connection shell 15 is installed on the transparent plate 151. The shape of the heating plate 152 is in a zigzag shape. The connection shell 15 can be sealed through the transparent plate 151 to protect the image acquisition unit 2 inside the connection shell 15 from damage caused by rain and snow intrusion. The transparent plate 151 and the camera of the image acquisition unit 2 can be heated through the heating plate 152, effectively preventing the formation of fog in cold weather and ensuring the clarity of image acquisition.

[0039] See Figure 7 and Figure 10, a stabilizing mechanism is provided at the bottom of the skateboard 12. The stabilizing mechanism includes a third screw 181 rotatably connected to the bottom of the skateboard 12. A threaded block 182 is threadedly connected to the third screw 181. The bottom of the threaded block 182 is connected to a slide rail 183. Two front and rear sliding plates 184 are slidably connected within the slide rail 183, and the two sliding plates 184 are arranged vertically. The sliding plate 184 includes a horizontal section and an arc section. The arc section of the sliding plate 184 is located outside the slide rail 183. A fixed arc clip 185 is connected to the arc section of the sliding plate 184. A movable arc clip 186 is hinged to the right side of the fixed arc clip 185. A fourth bolt 187 is provided on the movable arc clip 186. An arc-shaped chute for the fourth bolt 187 to slide is formed at the arc section of the sliding plate 184. A driving assembly is provided on the slide rail 183 for driving the two front and rear sliding plates 184 to approach and separate from each other. The driving assembly includes an outer diamond-shaped rod 188 rotatably connected to the right side wall of the slide rail 183. A gear 189 located within the slide rail 183 is connected to the outer diamond-shaped rod 188. An inner diamond-shaped threaded sleeve 1810 is slidably sleeved on the outer diamond-shaped rod 188 and is located to the right of the slide rail 183. An internal threaded sleeve 1811 is threadedly connected to the outside of the inner diamond-shaped threaded sleeve 1810. The internal threaded sleeve 1811 is fixedly connected to the right outer wall of the slide rail 183. Rack bars 1812 are connected to the horizontal sections of the two sliding plates 184. The rack bars 1812 are engaged with the gear 189.

[0040] First, according to the distance between two adjacent transmission cables 24 on the power tower, adjust the distance between the front and rear fixed arc clamps 185 and the movable arc clamps 186. 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 away from each other, thereby driving the two sliding plates 184 to move away from each other, and further causing the front and rear fixed arc clamps 185 and the movable arc clamps 186 to move away from each other. Similarly, reversing the inner diamond-shaped threaded sleeve 1810 can make the front and rear fixed arc clamps 185 and the movable arc clamps 186 approach each other. When the inner diamond-shaped threaded sleeve 1810 rotates, it slides on the outer diamond-shaped rod 188 and inside 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, the gear 189, the racks 1812, and the sliding plates 184 to prevent the fixed arc clamps 185 and the movable arc clamps 186 from moving back and forth by themselves. Then, put the front and rear fixed arc clamps 185 and the movable arc clamps 186 on two adjacent transmission cables 24 respectively. Then, rotate the movable arc clamp 186 in the direction close to the transmission cable 24 on the same side. Subsequently, tighten the bolt four 187 to lock the movable arc clamp 186 on the sliding plate 184, and fix it on the transmission cable 24 through the cooperation of the fixed arc clamp 185 and the movable arc clamp 186. Subsequently, insert the screw rod three 181 into the threaded block 182 to connect the sliding plate 12 and the slide rail 183 together. Finally, lock the clamping plate 3 on the cross arm 25 of the power tower through the clamping assembly 4, so that the stable mechanism can provide stable support for the whole device by clamping and fixing on two adjacent transmission lines, 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 with a measuring rod 22 facing the image acquisition unit 2. Scale lines are engraved on the measuring rod 22, which can measure the ice thickness on the sample cable 23. The measuring rod 22 can be heated through the heating rod 21 to avoid 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 with a connecting block 19 located outside the slide rail 183. The shape of the connecting block 19 is an inverted U shape. The left side of the inverted U-shaped connecting block 19 is installed with a CT power taking device 20 through bolts. The CT power taking device 20 is electrically connected with the micro-meteorological acquisition unit 1, the image acquisition unit 2, the weighing sensor 8, the heating sheet 107, the heating plate 152, and the heating rod 21.

[0043] The CT power taking device 20 is sleeved on the power transmission cable 24 of the power tower. When the current on the power transmission cable 24 passes through the CT power taking device 20, the CT power taking device 20 generates electric energy to supply power to the micro meteorological acquisition unit 1, the image acquisition unit 2, the weighing sensor 8, the heating sheet 107, the heating plate 152 and the heating rod 21. The CT power taking technology is a mature existing technology and will not be elaborated here. Compared with the power supply method through photovoltaic panels in the prior art, the CT power taking device 20 can provide a more stable and reliable power supply, which is not affected by weather conditions. This ensures that the equipment can continue to work normally even under adverse weather conditions such as cloudy days or overcast days, thereby improving the operation stability of the entire system and the reliability of data acquisition.
