Description

Technical Field

[0001] The present invention relates to the technical field of power grid installation protection equipment, and in particular to an optical fiber detection device with optical fiber cable dancing detection and a use method thereof. Background Art

[0002] Conductor galloping is a serious disaster that endangers the safe and stable operation of transmission lines. In addition, changes in the sag of transmission lines caused by conductor galloping can also cause tripping, resulting in serious accidents. Data show that 70% of power system failures are caused by the collapse of transmission towers and the dancing of ice on ground wires under strong winds. The collapse of transmission towers and power outages can cause huge economic losses. Especially when environmental disasters are serious, failures such as transmission lines will have a huge impact on people's daily lives and the national economy.

[0003] A real-time monitoring device for the dancing status of a transmission line cable with Chinese patent application number 202022051723.8 comprises: a casing, a power supply module, a main control circuit board, a dancing detection module, and a communication transmission module; the power supply module, the main control circuit board, the dancing detection module and the communication transmission module are arranged in the casing; a casing upper frame, a casing bottom frame and an isolation pad are provided in the casing, and a cable groove is provided at the lower end of the casing upper frame and the upper end of the casing bottom frame; the casing upper frame and the casing bottom frame lock the cable tightly in the cable groove through the isolation pad; the power supply module, the main control circuit board, the dancing detection module and the communication transmission module are respectively installed in the casing upper frame and the casing bottom frame, but in the actual use of the device, it is difficult to slow down the dancing of the cable, so that the cable connection is easily broken when the cable dances violently.

[0004] A monitoring device for power transmission lines with Chinese patent application number 202220471612.9 includes a mounting box fixed on the wire, and the mounting box is provided with an MCU module, a communication module connected to the MCU module, a positioning module, a first acceleration sensor, a second acceleration sensor and an alarm module. The utility model uses the first acceleration sensor and the second acceleration sensor to detect the acceleration of the cable dancing, but the device is difficult to slow down the dancing of the cable, so that the cable connection is easy to break when the cable dances violently.

[0005] However, the shock-proof effect of the shock-proof component is limited. In severe weather, the cable dances violently, which can easily cause the cable to break at the fixing block. In addition, when the cable surface is covered with ice, when the wind blows on the cable, the flow of wind changes due to the influence of ice, which in turn aggravates the dancing of the cable. At the same time, ice will also increase the weight of the cable. When the cable dances, the cable is more likely to break at the fixing block. Summary of the invention

[0041] The clamping device 2 includes a mounting block 201, a connecting plate 202 is rotatably provided on one side of the mounting block 201 close to the cable 3, an inclination sensor is provided on the connecting plate 202, a connecting rod 203 is slidably provided on one side of the connecting plate 202 close to the cable 3, a clamping ring 204 is provided on the side end of the connecting rod 203, a pressure sensor is provided between the clamping ring 204 and the connecting rod 203, when the cable 3 dances up and down, it will move up and down with the clamping ring 204, thereby causing the connecting plate 202 to deflect, and the deflection angle of the connecting plate 202 will be detected by the inclination sensor, and when the cable 3 dances left and right, it will generate lateral pressure on the clamping ring 204, and the pressure sensor can detect the lateral pressure on the clamping ring 204, and the dancing frequency and amplitude of the cable 3 can be indirectly obtained through the detection cooperation of the inclination sensor and the pressure sensor.

[0042] The clamping device 2 also includes a fixed chassis 216, a limited slide groove 217 is provided on the fixed chassis 216, a clamping plate 218 is slidably provided in the limited slide groove 217, the fixed block 109 is located between the clamping plate 218 and the fixed chassis 216, a fixed screw 219 is rotatably provided on the clamping plate 218, the fixed screw 219 is threadedly matched with the fixed chassis 216, and a connecting rod 220 is provided on both the fixed chassis 216 and the clamping plate 218. The connecting rod 220 It is connected to the mounting block 201 so that the bottom end of the fixed block 109 fits with the top end of the fixed chassis 216, and the fixing screw 219 is rotated so that the fixing screw 219 and the fixed chassis 216 are threadedly matched, thereby making the clamping plate 218 approach the fixed block 109, and the fixed block 109 is clamped with the cooperation of the clamping plate 218 and the fixed chassis 216, and at the same time, the clamping device 2 is fixed on the fixed block 109 to ensure the stability of the clamping device 2 when used.

[0043] The clamping ring 204 is made of insulating material, the fixing block 109 is also made of insulating material, and there are gaps between the multiple ceramic insulating disks 108.

[0044] The shockproof component 4 includes an intermediate sleeve 401, a connecting rod 402 is arranged in the middle of the intermediate sleeve 401, and a first shockproof rod 406 and a second shockproof rod 415 are arranged on both sides of the connecting rod 402 respectively. A lower fixing ring 416 is arranged at the top of the intermediate sleeve 401, and an upper fixing ring 417 is arranged at the top of the lower fixing ring 416. The cable 3 passes through the upper fixing ring 417 and the lower fixing ring 416, and a fixing bolt 418 is arranged between the upper fixing ring 417 and the lower fixing ring 416. The upper fixing ring 417 and the lower fixing ring 416 are attached to the upper and lower sides of the cable 3. The upper fixing ring 417 and the lower fixing ring 416 are connected and fixed with the assistance of the fixing bolt 418. When the cable 3 is dancing, the first shockproof rod 406 and the second shockproof rod 415 will generate corresponding reaction force, thereby reducing the dancing of the cable 3.

[0045] In summary, during the use of the present invention, after the hanging bolt 103 passes through the first through hole 104, the hanging bolt 103 also passes through the hanging position of the optical fiber bracket, and then the hanging nut 105 and the hanging bolt 103 are tightened, and then the locking column 107 is inserted into the locking hole 106, and the locking column 107 is bent to ensure the firmness of the connection between the hanging bolt 103 and the hanging bracket 102, and the cable 3 passes through the fixing block 109 for hanging.

[0046] The upper fixing ring 417 and the lower fixing ring 416 are fitted onto the upper and lower sides of the cable 3, and are connected and fixed with the aid of fixing bolts 418. When the cable 3 is dancing, the first shockproof rod 406 and the second shockproof rod 415 will generate corresponding reaction forces, thereby reducing the dancing of the cable 3.

[0047] Make the bottom end of the fixed block 109 fit with the top end of the fixed chassis 216, rotate the fixing screw 219, and the fixing screw 219 and the fixed chassis 216 are threadedly matched, so that the clamping plate 218 is moved closer to the fixed block 109, and the fixed block 109 is clamped under the mutual cooperation of the clamping plate 218 and the fixed chassis 216, and the clamping device 2 is fixed on the fixed block 109.

[0048] When the cable 3 dances due to external factors, the cable 3 will move up and down with the clamping ring 204, thereby causing the connecting plate 202 to deflect, and the deflection angle of the connecting plate 202 will be detected by the inclination sensor. When the cable 3 dances left and right, it will produce lateral pressure on the clamping ring 204, and the pressure sensor can detect the lateral pressure on the clamping ring 204. The dancing frequency and amplitude of the cable 3 can be indirectly obtained through the detection coordination of the inclination sensor and the pressure sensor.

[0049] Based on the above-mentioned optical fiber detection device with optical fiber cable dancing detection, although the device can detect the dancing of the cable 3 during use, the anti-vibration effect of the anti-vibration component 4 is limited during the specific use of the device. In bad weather, the cable 3 dances violently, which can easily cause the cable 3 to break at the fixing block 109. When the surface of the cable 3 is covered with ice, when the wind blows on the cable 3, the flow of wind changes due to the influence of ice, which in turn aggravates the dancing of the cable 3. At the same time, ice will also increase the weight of the cable 3. When the cable 3 dances, the cable 3 and the fixing block 109 are more likely to break. For this reason, we propose the following technical solutions:

[0050] like Figures 1 to 8 As shown, an annular cylinder 205 is provided at the side end of the mounting block 201, a first connecting pipe 206 is provided at the side end of the annular cylinder 205, a second connecting pipe 207 is provided at the side end of the connecting plate 202, a first cavity 208 is provided in the connecting plate 202, antifreeze is provided in the first cavity 208 and the annular cylinder 205, a first piston plate 209 is provided on one side of the connecting rod 203 located in the first cavity 208, the curvature of the clamping ring 204 matches the cable 3, when the clamping ring 204 is subjected to the thrust of the lateral dancing of the cable 3, the clamping ring 204 will move toward the direction of the connecting plate 202, the movement of the clamping ring 204 drives the movement of the first piston plate 209 through the assistance of the connecting rod 203, and the movement of the first piston plate 209 cooperates with the first cavity 208 to discharge the antifreeze in the first cavity 208 from the second connecting pipe 207.

[0051] A connecting shaft 210 is provided on the connecting plate 202, and the connecting shaft 210 is rotatably provided on the mounting block 201. A disc 211 is provided at the end of the connecting shaft 210, and a push plate 212 is provided at the side end of the disc 211. A clamping groove 213 is provided on the inner wall of the annular cylinder 205. A second piston plate 214 is provided in the annular cylinder 205, and a push rod 215 is provided on the side of the second piston plate 214 close to the push plate 212. An elastic protrusion is provided on the outer ring of the second piston plate 214. When the second piston plate 214 slides through the clamping groove 213 in the annular cylinder 205, the elastic protrusion will pop out and clamp with the clamping groove 213. When the cable 3 dances up and down, the cable 3 will move up and down with the clamping ring 204, and the up and down movement of the clamping ring 204, with the assistance of the connecting rod 203, makes the connecting plate 202 rotate around the connecting shaft 210 as the center, thereby making the disc 211 rotate, and the rotation of the disc 211 will make the push plate 212 move, and the movement of the push plate 212 drives the movement of the push rod 215, and the movement of the push rod 215 makes the second piston plate 214 move, and the movement of the second piston plate 214 cooperates with the annular cylinder 205 to discharge the antifreeze in the annular cylinder 205 through the first connecting pipe 206.

[0052] A limiting hole 403 is provided on the side of the connecting rod 402 away from the suspension device 1, a telescopic rod 404 is provided in the limiting hole 403, a spring 405 is provided between the telescopic rod 404 and the connecting rod 402, a first shockproof rod 406 is provided at the end of the telescopic rod 404, a knocking block 407 is provided on the first shockproof rod 406, the first connecting pipe 206 and the second connecting pipe 207 are both connected to the limiting hole 403, a second through hole 408 is provided in the middle of the telescopic rod 404, a second cavity 409 is provided in the first shockproof rod 406, and the second cavity 409 is connected to the limiting hole 403 through the second through hole 408, the antifreeze liquid discharged from the first connecting pipe 206 and the second connecting pipe 207 will enter the limiting hole 403, so that the telescopic rod 404 moves in the direction away from the middle sleeve 401, thereby increasing the swing amplitude of the first shockproof rod 406, thereby enhancing the reaction force generated by the first shockproof rod 406 to offset the stronger shaking of the cable 3.

[0053] A pressure valve is provided in the second through hole 408, a third piston plate 410 is slidably provided in the second cavity 409, an electric-controlled damping cylinder 411 is provided on the side of the third piston plate 410 close to the telescopic rod 404, a top block 412 is provided on the side of the third piston plate 410 away from the telescopic rod 404, a knocking block 407 slides up and down in the first shockproof rod 406, an auxiliary block 413 is provided at the lower end of the knocking block 407, a positioning ring 414 is provided at the upper end of the auxiliary block 413 of the knocking block 407, and the contact surface between the lower end of the auxiliary block 413 and the top block 412 is set as an inclined surface. As the dancing of the cable 3 intensifies, the antifreeze in the limiting hole 403 gradually increases, thereby gradually increasing the pressure on the pressure valve. When the pressure exceeds the threshold, the antifreeze in the limiting hole 403 passes through The second through hole 408 enters into the second cavity 409, and the antifreeze liquid entering into the second cavity 409 will generate a thrust on the third piston plate 410, causing the third piston plate 410 to move away from the telescopic rod 404, thereby causing the top block 412 to generate a thrust on the auxiliary block 413. Due to the influence of the inclined surface of the contact surface between the top block 412 and the auxiliary block 413, the knocking block 407 will move upward. On the one hand, the antifreeze liquid enters into the second cavity 409 to increase the weight of the first shockproof rod 406, thereby strengthening the reaction force generated by the first shockproof rod 406 to offset the stronger shaking of the cable 3. On the other hand, the extension of the knocking block 407 will knock on the cable 3 as the first shockproof rod 406 shakes, thereby knocking and removing the ice on the cable 3.

[0054] A second shock-proof rod 415 is disposed on a side of the connecting rod 402 away from the first shock-proof rod 406 .

[0055] In summary, when the cable 3 is shaking laterally, the clamping ring 204 will be pushed by the lateral shaking of the cable 3, and the clamping ring 204 will move in the direction of the connecting plate 202. The movement of the clamping ring 204 drives the movement of the first piston plate 209 with the assistance of the connecting rod 203, and the movement of the first piston plate 209 cooperates with the first cavity 208 to make the antifreeze liquid in the first cavity 208 discharged from the second connecting tube 207, and the antifreeze liquid discharged from the second connecting tube 207 will enter the limiting hole 403, and the antifreeze liquid entering the limiting hole 403 will push the telescopic rod 404 to move in the direction away from the middle sleeve 401, and after the telescopic rod 404 moves, the swing amplitude of the first shockproof rod 406 will be increased, thereby enhancing the reaction force generated by the first shockproof rod 406, thereby offsetting the stronger lateral shaking of the cable 3 under the influence of the reaction force generated by the first shockproof rod 406.

[0056] When the cable 3 is vertically shaken, the cable 3 will move up and down with the clamping ring 204, and the up and down movement of the clamping ring 204 is assisted by the connecting rod 203 to make the connecting plate 202 rotate around the connecting shaft 210 as the center, so that the disc 211 rotates, and the rotation of the disc 211 causes the push plate 212 to move, and the movement of the push plate 212 drives the movement of the push rod 215, and the movement of the push rod 215 causes the second piston plate 214 to move, and the movement of the second piston plate 214 cooperates with the annular cylinder 205 to move the annular The antifreeze in the cylinder 205 is discharged through the first connecting pipe 206, and the antifreeze discharged from the first connecting pipe 206 enters the limiting hole 403. The antifreeze entering the limiting hole 403 pushes the telescopic rod 404 to move away from the middle sleeve 401. After the telescopic rod 404 moves, the swing amplitude of the first shockproof rod 406 is increased, thereby enhancing the reaction force generated by the first shockproof rod 406, thereby offsetting the stronger vertical shaking of the cable 3 under the influence of the reaction force generated by the first shockproof rod 406.

[0057] In an actual environment, the dancing of the cable 3 is irregular, and it occurs both horizontally and vertically. When the cable 3 shakes horizontally and vertically at the same time, the antifreeze liquid discharged from the first connecting tube 206 and the second connecting tube 207 will enter the limiting hole 403 together, making the moving distance of the telescopic rod 404 longer, thereby making the reaction force generated by the first shock-absorbing rod 406 stronger to offset the shaking of the cable 3.

[0058] As the degree of the cable 3 dancing increases, the continuous entry of the antifreeze in the limit hole 403 will cause the telescopic rod 404 to move to a limit distance. At this time, the antifreeze in the limit hole 403 will act on the pressure valve in the second through hole 408. When the pressure on the pressure valve exceeds the threshold, the pressure valve will open, and the antifreeze in the limit hole 403 will enter the second cavity 409 through the second through hole 408, thereby increasing the weight of the first shockproof rod 406. After the weight of the first shockproof rod 406 increases, the reaction force generated by the first shockproof rod 406 when the cable 3 dances will also be correspondingly strengthened, so that the first shockproof rod 406 can offset the stronger dancing of the cable 3.

[0059] The antifreeze liquid entering the second cavity 409 will generate a thrust on the third piston plate 410, causing the third piston plate 410 to move away from the telescopic rod 404, thereby causing the top block 412 to generate a thrust on the auxiliary block 413. Due to the influence of the inclined surface of the contact surface between the top block 412 and the auxiliary block 413, the knocking block 407 will move upward. At this time, when the first shockproof rod 406 is shaking, the extension of the knocking block 407 will knock on the cable 3, thereby directly transmitting the reaction force of the first shockproof rod 406 to the cable 3, and disrupting the dancing frequency of the cable 3 with the assistance of the knocking block 407, so as to reduce the dancing of the cable 3.

[0060] When ice is formed on the cable 3, the wind blows the cable 3. Since the ice on the cable 3 changes the original circular structure of the cable 3, the wind flow causes the cable 3 to dance more strongly. At this time, with the strong dancing of the cable 3, the movement of the second piston plate 214 will pass through the positioning groove 213, and the elastic protrusion on the second piston plate 214 will pop out and engage with the positioning groove 213, so that the second piston plate 214 cannot move, and the extension of the knocking block 407 will cause the positioning ring 414 to also extend and engage, so that the knocking block 407 cannot move, and the antifreeze in the limiting hole 403 can no longer flow back into the annular cylinder 205. At this time, the electronically controlled damping cylinder 411 is controlled to operate in the reverse direction, so that the third piston plate 410 moves toward the direction close to the telescopic rod 404, and the third piston plate 4 The movement of 10 will cause the antifreeze fluid in the second cavity 409 to return to the limiting hole 403, and the increase in the antifreeze fluid pressure in the limiting hole 403 will cause the antifreeze fluid to flow back into the first cavity 208, so that the clamping ring 204 can tightly clamp the cable 3. At this time, when the cable 3 is dancing, the shaking of the connection between the cable 3 and the fixed block 109 will be weakened, thereby avoiding the breakage of the cable 3 at the fixed block 109, and the clamping of the cable 3 by the clamping ring 204 will also weaken the shaking of the cable 3. When the first shockproof rod 406 shakes to offset the shaking of the cable 3, the knocking block 407 will knock on the cable 3, thereby breaking the ice on the cable 3. At this time, along with the shaking of the cable 3, the ice on the cable 3 can be shaken off and cleaned, and the shaking of the cable 3 will also be slowed down after the ice is cleaned.

[0061] The present invention provides a first piston plate 209, a second piston plate 214, a third piston plate 410, a knocking block 407, an electrically controlled damping cylinder 411, a pressure valve and other components, so that when the device encounters different degrees of dancing of the cable 3, the telescopic rod 404 can be extended from the limiting hole 403 and the weight of the first shock-proof rod 406 can be increased to offset the shaking of the cable 3. When the cable 3 is covered with ice and violently dances under the influence of wind, the cable 3 is tightly clamped by the clamping ring 204 to avoid the breakage of the connection between the cable 3 and the fixed block 109. The ice on the cable 3 is cleaned by the cooperation of the knocking of the knocking block 407 and the dancing of the cable 3, thereby improving the effect and convenience of the use of the equipment.

[0063] Step 1: First, pass the cable 3 through the fixing block 109 and hang and fix the suspension device 1 on the optical fiber bracket to complete the hanging and fixing of the cable 3.

[0065] Step 3: When the cable 3 is dancing, the dancing frequency and the dancing amplitude of the cable 3 are detected by the cooperation of the pressure sensor and the inclination sensor, and the detection data is transmitted to the terminal via wireless signals.

[0066] Step 4: When the cable 3 is dancing, the dancing of the cable 3 is mitigated by the cooperation among the suspension device 1 , the clamping device 2 and the shockproof component 4 , so as to avoid damage to the cable 3 .
