Description

Technical Field

[0001] This invention relates to the field of power line wind disaster monitoring technology, specifically a power transmission line wind disaster monitoring system based on fiber optic sensing. Background Technology

[0002] Wind-induced vibration phenomena such as galloping and light wind vibration can cause arc burns, hardware damage, and even serious accidents such as broken strands, broken wires, and tower collapses, which seriously affect the stable operation of the power system. If the wind-induced vibration of transmission lines can be monitored and assessed in real time, and the fault location can be quickly located when a fault occurs, the transmission line fault can be quickly restored, and targeted measures can be taken for areas with more disasters.

[0003] One existing technology utilizes multi-parameter distributed optical fiber sensing for continuous spatial monitoring. Its basic principle involves a shared light source for both BOTDR and φOTDR systems, employing a narrow linewidth source. An acousto-optic modulator is used, and the optical modulator converts continuous light into pulsed light. To increase the monitoring range, the optical amplifier employs a two-stage amplification mode combining Raman spectroscopy and erbium-doped amplification. After gaining, the light passes through a bandpass filter into an optical circulator. The bandpass filter removes noise from the optical amplifier. After passing through the circulator and entering the OPGW, the backscattered light returns to the circulator and enters the optical coupler, where it is split into two beams for BOTDR and φOTDR detection, respectively. The BOTDR uses a coherent monitoring method. The middle Bragg grating is used to filter out Rayleigh scattering light. After passing through a photoelectric converter, the light enters the signal processing system. After frequency sweeping and Lorentz fitting, the Brillouin frequency shift value is obtained. The φOTDR adopts a direct detection method because the intensity of Brillouin scattering light is much lower than that of Rayleigh scattering light (approximately three orders of magnitude), so its influence can be ignored. Currently, under ideal experimental conditions, bare fiber tests show that the sensing distance of the BOTDR part can reach 80km, and the sensing distance of the OTDR can reach 120km. Its vibration monitoring range is 0-400Hz, and the strain monitoring range can reach up to 5000μuε. This requires the use of a photoelectric converter to convert electrical signals into optical signals and send them out. At the same time, the received optical signals are converted back into electrical signals.

[0004] When transported or used, photoelectric converters are subject to vibrations from impacts or bumps. Since photoelectric converters contain a large number of electronic components, these components are easily damaged by stress during vibrations, which increases the transportation and usage costs of photoelectric converters.

[0005] Therefore, there is an urgent need to invent a power transmission line wind disaster monitoring system based on fiber optic sensing to solve the above problems. Summary of the Invention

A fixing frame is provided inside the body, and symmetrically arranged anti-detachment grooves are uniformly formed on the outer wall of the fixing frame. The ball bearing contacts the inner wall of the anti-detachment groove to support the fixing frame. The fixing frame is used to fix electronic components, and the lower support tubes are connected by flexible tubing. The upper support tubes are interconnected via flexible hoses. A first pressure check valve, communicating with the interior of the lower support tube, is fixedly connected to the outer wall of the lower support tube via a flexible hose. A second pressure check valve, communicating with the interior of the upper support tube, is also fixedly connected to the outer wall of the upper support tube via a flexible hose. The flow directions of the first and second pressure check valves are opposite. An air bladder is fixedly connected to the outer wall of the mounting frame. A cooling mechanism is provided on the exterior of the machine body for dissipating heat from the interior of the machine body.

[0007] Preferably, the cooling mechanism includes a water cover, which is fixedly connected to the right outer wall of the machine body. The water cover has grooves evenly distributed on its wall. An air outlet pipe is fixedly connected to the top inner wall of the water cover. An air pump is fixedly connected to the top of the machine body. The air inlet of the air pump communicates with the interior of the machine body. The air outlet of the air pump penetrates the outer wall of the water cover to its interior and communicates with one end of the air outlet pipe. A through hole is formed in the inner wall of the machine body. The through hole communicates with the interior of the water cover, and meltblown fabric is fixedly connected to the inner wall of the through hole.

[0008] Preferably, the lower outer ring wall of the sliding tube and the inner ring wall of the support tube are rotatably connected. The outer wall of the sliding tube is provided with a threaded groove. A ball head rod is fixedly connected to the inner ring wall of the support tube near the fixed frame. The ball head of the ball head rod extends into the threaded groove and contacts its inner wall. Impellers are uniformly fixedly connected to the outer ring wall of the sliding tube near the fixed frame.

[0009] Preferably, a water-cooling pipe is fixedly connected to the inner wall of the machine body, and one end of the water-cooling pipe passes through the inner wall of the machine body to the water cover and communicates with the interior of the water cover.

[0013] Preferably, a rubber ring is fixedly connected to the inner wall of the anti-detachment groove.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. This invention, by setting up a body, support tube, sliding tube, ball bearings, fixing frame, anti-detachment groove, first pressure check valve, second pressure check valve, airbag, cooling mechanism, threaded groove, ball head rod, impeller, and water cooling tube, uses the ball bearings to buffer and suspend the electronic components fixed by the fixing frame to reduce vibration, thereby reducing the probability of electronic components being damaged by overstress due to vibration. At the same time, it prevents electronic components from vibrating on their own after vibration, and during vibration reduction, it cooperates with the cooling mechanism to increase the heat dissipation effect of the cooling mechanism on the inside of the body.

[0016] 2. By incorporating a sponge, the sponge is fixedly connected to the inner wall of the water-cooling pipe, which can disperse air bubbles as they pass through the sponge, making the air bubbles denser and thus increasing the ripple effect of the water inside the water-cooling pipe.

Obviously, the described embodiments are only some embodiments of the present invention, 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.

Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] like Figures 1 to 5As shown; a transmission line wind disaster monitoring system based on fiber optic sensing includes a body 1, which is sealed. Symmetrically arranged support tubes 2 are uniformly fixed to the inner wall of the body 1. A sliding tube 3 is provided on the inner wall of each support tube 2, and the lower outer wall of the sliding tube 3 is slidably and sealingly connected to the inner wall of the support tube 2. A ball bearing 4 is provided at the top of the sliding tube 3. A fixing frame 5 is provided inside the body 1. Symmetrically arranged anti-detachment grooves 6 are uniformly formed on the outer wall of the fixing frame 5. The ball bearing 4 contacts the inner wall of the anti-detachment groove 6 to support the fixing frame 5. The fixing frame 5 is used to fix electronic components. The lower support tubes 2 are interconnected via flexible hoses. The upper... The internal parts of the support tubes 2 are interconnected by hoses. A first pressure check valve 7, which communicates with the internal parts of the lower support tube 2, is fixedly connected to the outer wall of the lower support tube 2. The first pressure check valve 7 is connected to the internal parts of the upper support tube 2 via a hose. A second pressure check valve 8, which communicates with the internal parts of the upper support tube 2, is fixedly connected to the outer wall of the upper support tube 2 via a hose. The flow directions of the first pressure check valve 7 and the second pressure check valve 8 are opposite. An air bag 9 is fixedly connected to the outer ring wall of the fixing frame 5. A cooling mechanism is provided on the outside of the body 1 for dissipating heat from the inside of the body 1.

[0028] The cooling mechanism includes a water cover 10, which is fixedly connected to the outer right side wall of the body 1. The wall of the water cover 10 is evenly provided with grooves 22. An air outlet pipe 11 is fixedly connected to the inner top wall of the water cover 10. An air pump 12 is fixedly connected to the top of the body 1. The air inlet of the air pump 12 is connected to the interior of the body 1. The air outlet of the air pump 12 penetrates the outer wall of the water cover 10 to its interior and is connected to one end of the air outlet pipe 11. A through hole 13 is provided on the inner wall of the body 1. The through hole 13 is connected to the interior of the water cover 10, and a meltblown cloth 14 is fixedly connected to the inner wall of the through hole 13.

[0029] In use, when the body 1 vibrates up and down, its internal electronic components move downwards. These components move downwards along with the mounting bracket 5. As the mounting bracket 5 moves downwards, it compresses the lower ball bearing 4. The ball bearing 4, under this pressure, compresses the sliding tube 3, causing it to slide downwards along the inner wall of the support tube 2. As the sliding tube 3 slides downwards along the inner wall of the support tube 2, it compresses the gas inside both the support tube 2 and the sliding tube 3, increasing the gas pressure. This compression of the gas inside the support tube 2 and the sliding tube 3, along with the reaction force generated by the compression, cushions the sliding tube 3. Furthermore, as the gas inside the support tube 2 and the sliding tube 3... When the gas is compressed, the gas pressure increases, and the gas will be discharged from the first pressure check valve 7 into the interior of the upper support tube 2. This reduces the amount of gas inside the lower support tube 2 and the sliding tube 3, thus preventing the sliding tube 3 from rebounding and vibrating under the reaction force generated by the compressed gas after sliding into the support tube 2 to compress the gas. As a result, when the fixed frame 5 moves downward, the sliding tube 3 buffers and suspends the electronic components fixed to the fixed frame 5 through the ball bearing 4 to reduce vibration. After the gas in the lower support tube 2 is discharged into the upper support tube 2, the upper sliding tube 3 will slide downward along the inner wall of the support tube 2 with the fixed frame 5 under its own weight and the compression of the incoming gas, preparing for the subsequent upward movement of the fixed frame 5.

[0030] When the mounting bracket 5 and the electronic components move upward, the mounting bracket 5 will push the upper ball bearing 4, thereby causing the upper sliding tube 3 to suspend and dampen the upward-moving mounting bracket 5. At this time, the gas inside the upper support tube 2 will be discharged into the lower support tube 2 through the second pressure check valve 8. Similarly, the lower support tube 2 and the sliding tube 3 will prepare for the next downward movement of the mounting bracket 5.

[0031] Furthermore, when the vibration angle of the fixed frame 5 causes it to tilt and move up and down, the fixed frame 5 can also tilt to squeeze the ball bearing 4 on one side. This ensures that even if the fixed frame 5 is tilted, the ball bearing 4 in the tilt direction can effectively dampen the fixed frame 5. When the fixed frame 5 moves laterally due to vibration, an airbag 9 is fixedly connected to the outer wall of the fixed frame 5. When the fixed frame 5 moves laterally, the other end of the airbag 9 can contact the inner wall of the body 1, thereby squeezing the airbag 9 when the fixed frame 5 moves laterally. The airbag 9 provides cushioning and shock absorption for the fixed frame 5. When the fixed frame 5 is tilted, the ball bearing 4 will slide on the inner wall of the anti-detachment groove 6. When the fixed frame 5 is tilted at a certain angle, the inner ring wall of the anti-detachment groove 6 will block the ball bearing 4, thereby preventing the ball bearing 4 from detaching from the anti-detachment groove 6 and no longer being able to support the fixed frame 5.

[0032] When its internal electronic components operate, they generate a large amount of heat, causing the internal temperature of the unit 1 to rise. Overheating of electronic components can lead to a decrease in performance and, in severe cases, burn them out. Therefore, the unit 1 is sealed to prevent external dust and moisture from entering and affecting the internal electronic components. An air pump 12 is fixedly connected to the top of the unit 1. When the unit 1 needs cooling, the operator starts the air pump 12. The air pump 12 begins to draw air from inside the unit 1, thus drawing out the hot air. The hot air is then discharged from the air pump 12 outlet into the air outlet pipe 11 and then discharged from the other end of the air outlet pipe 11. The water cover 10 contains water, so when the hot air is discharged from the air outlet pipe 11, it passes through the water in the form of bubbles, allowing the water to absorb the heat from the hot air. The air then reaches the upper part of the water cover 10. As the air pump 12 continues to operate, the air is cooled down. Gas re-enters the interior of the machine body 1 through the through hole 13. A meltblown fabric 14 is fixedly connected to the inner wall of the through hole 13. The meltblown fabric 14 is a water-resistant but air-resistant material, allowing air to enter the interior of the machine body 1. However, the water vapor in the water cover 10 cannot enter the interior of the machine body 1 and affect the electronic components inside the machine body 1. This achieves the purpose of cooling the interior of the machine body 1 by internal circulation and cooling the hot air inside the machine body 1 when heat dissipation is required. This also prevents dust and water vapor from entering the interior of the machine body 1 and affecting the electronic components inside the machine body 1. Furthermore, grooves 22 are evenly provided on the wall of the water cover 10. The grooves 22 on the inner wall of the water cover 10 increase the contact area between the water and the inner wall of the water cover 10, and the grooves 22 on the outer wall of the water cover 10 increase the contact area between the outer wall of the water cover 10 and the outside air. This makes it easier for the water in the water cover 10 to absorb the heat inside the machine body 1 and dissipate it, thereby increasing the cooling effect on the gas discharged by the air pump 12.

[0033] like Figure 3 and Figure 4 As shown; the lower outer ring wall of the sliding tube 3 and the inner ring wall of the support tube 2 are rotatably connected. The outer wall of the sliding tube 3 is provided with a threaded groove 15. A ball head rod 16 is fixedly connected to the inner ring wall of the support tube 2 near the fixed frame 5. The ball head part of the ball head rod 16 extends into the threaded groove 15 and contacts its inner wall. Impellers 17 are uniformly fixedly connected to the outer ring wall of the sliding tube 3 near the fixed frame 5.

[0034] In use, when the sliding tube 3 slides along the inner wall of the support tube 2, the inner wall of the threaded groove 15 on the outer ring wall of the sliding tube 3 will squeeze the ball head of the ball head rod 16 fixedly connected to the upper inner ring wall of the support tube 2. The reaction force generated by the squeeze on the ball head rod 16 will also squeeze the inner wall of the threaded groove 15, thereby causing the sliding tube 3 to rotate as it slides along the inner wall of the support tube 2. The impeller 17, which is uniformly fixedly connected to the upper outer ring wall of the sliding tube 3, will also rotate along with it. The rotation of the impeller 17 will cause the gas inside the machine body 1 to start flowing, thereby making the hot air inside the machine body 1 more evenly distributed inside the machine body 1 and easier to be sucked away by the air pump 12, thus increasing the cooling effect inside the machine body 1.

[0035] like Figure 2 and Figure 5 As shown; a water-cooling pipe 18 is fixedly connected to the inner wall of the body 1. One end of the water-cooling pipe 18 passes through the inner wall of the body 1 to the water cover 10 and communicates with the interior of the water cover 10.

[0036] In use, a water-cooling pipe 18 is fixedly connected to the inner wall of the body 1. The water-cooling pipe 18 is connected to the inside of the water cover 10. The water in the water cover 10 will enter the interior of the water-cooling pipe 18. When the heat inside the body 1 comes into contact with the water-cooling pipe 18, it will transfer the heat to the water-cooling pipe 18. The water-cooling pipe 18 will then transfer the heat to the water inside it, thereby increasing the cooling effect on the interior of the body 1. Furthermore, the rotation of the impeller 17 allows the hot air inside the body 1 to be blown toward the water-cooling pipe 18, thereby increasing the cooling effect of the water-cooling pipe 18 on the interior of the body 1.

[0037] like Figure 5 As shown; one end of the air outlet pipe 11 extends into the interior of the water cooling pipe 18 and is close to the inner wall of the end of the water cooling pipe 18 away from the water cover 10.

[0038] A sponge 19 is fixedly connected to the inner wall of the water-cooled pipe 18;

[0039] In use, one end of the exhaust pipe 11 extends into the interior of the water-cooling pipe 18. This causes the gas discharged into the water-cooling pipe 18 to flow in the form of bubbles when the exhaust pipe 11 is venting. This causes the water inside the water-cooling pipe 18 to ripple, allowing the water inside the water-cooling pipe 18 to absorb the heat absorbed by the pipe wall of the water-cooling pipe 18 more evenly. This increases the cooling effect of the water-cooling pipe 18 on the interior of the machine body 1. In addition, a sponge 19 is fixedly connected to the inner wall of the water-cooling pipe 18. When the bubbles pass through the sponge 19, they are broken up by the sponge 19, making the bubbles denser, thereby increasing the ripple effect of the water inside the water-cooling pipe 18.

[0040] like Figure 2 and Figure 3As shown; symmetrically arranged springs 20 are uniformly fixedly connected to the inner wall of the body 1;

[0041] In use, when the amplitude of the vertical vibration of the machine body 1 varies greatly, in order to prevent the sliding tube 3 from failing to slide in time, resulting in insufficient sliding distance of the sliding tube 3 which should slide upward or downward and thus not being ready for the next shock absorption, symmetrically arranged springs 20 are evenly fixedly connected to the inner wall of the machine body 1. When the amplitude of the vibration of the machine body 1 is large, the outer wall of the fixing frame 5 will hit the springs 20. The springs 20 are compressed and shortened, and then return to their original length and extend, pushing the fixing frame 5, thereby preventing the fixing frame 5 from staying on one side and failing to slide back in time.

[0042] like Figure 3 As shown; a rubber ring 21 is fixedly connected to the inner ring wall of the anti-detachment groove 6;

[0043] When in use, when the inner ring wall of the anti-detachment groove 6 blocks the ball 4, the ball 4 will come into contact with the rubber ring 21. The rubber ring 21 cushions the ball 4, thereby preventing the ball 4 from being damaged after colliding with the inner wall of the anti-detachment groove 6, which would hinder the rolling effect of the ball 4.

[0044] Working principle of this invention:

[0045] Refer to the instruction manual appendix Figure 1-5 When the body 1 vibrates up and down, its internal electronic components move downwards. These components move downwards along with the mounting frame 5. As the mounting frame 5 moves downwards, it compresses the lower ball bearing 4. The ball bearing 4, under this pressure, compresses the sliding tube 3, causing it to slide downwards along the inner wall of the support tube 2. As the sliding tube 3 slides downwards along the inner wall of the support tube 2, it compresses the gas inside both the support tube 2 and the sliding tube 3, increasing the gas pressure. This compression of the gas inside the support tube 2 and the sliding tube 3, along with the reaction force generated by the compression, cushions the sliding tube 3. Furthermore, as the gas inside the support tube 2 and the sliding tube 3... When the gas is compressed, the gas pressure increases, and the gas is discharged from the first pressure check valve 7 into the interior of the upper support tube 2. This reduces the amount of gas inside the lower support tube 2 and the sliding tube 3, thus preventing the sliding tube 3 from rebounding and vibrating under the reaction force generated by the compressed gas after sliding into the support tube 2 to compress the gas. As a result, when the fixed frame 5 moves downward, the sliding tube 3 buffers and suspends the electronic components fixed to the fixed frame 5 through the ball bearings 4 to reduce vibration. After the gas in the lower support tube 2 is discharged into the upper support tube 2, the upper sliding tube 3 will slide downward along the inner wall of the support tube 2 with the fixed frame 5 under its own weight and the compression of the incoming gas, preparing for the subsequent upward movement of the fixed frame 5.

[0046] When the mounting bracket 5 and the electronic components move upward, the mounting bracket 5 will push the upper ball bearing 4, thereby causing the upper sliding tube 3 to suspend and dampen the upward-moving mounting bracket 5. At this time, the gas inside the upper support tube 2 will be discharged into the lower support tube 2 through the second pressure check valve 8. Similarly, the lower support tube 2 and the sliding tube 3 will prepare for the next downward movement of the mounting bracket 5.

[0047] Furthermore, when the fixed frame 5 tilts due to vibration, causing it to move up and down, the fixed frame 5 can tilt and squeeze the ball bearing 4 on one side. This ensures that even if the fixed frame 5 tilts, the ball bearing 4 in the tilt direction can effectively dampen the fixed frame 5. When the fixed frame 5 moves laterally due to vibration, an airbag 9 is fixedly connected to the outer wall of the fixed frame 5. When the fixed frame 5 moves laterally, the other end of the airbag 9 can contact the inner wall of the body 1, thereby squeezing the airbag 9 when the fixed frame 5 moves laterally. The airbag 9 provides cushioning and shock absorption for the fixed frame 5. When the fixed frame 5 tilts, the ball bearing 4 will slide on the inner wall of the anti-detachment groove 6. When the fixed frame 5 tilts at a certain angle, the inner ring wall of the anti-detachment groove 6 will block the ball bearing 4, thereby preventing the ball bearing 4 from detaching from the anti-detachment groove 6 and no longer being able to support the fixed frame 5.

[0048] When its internal electronic components operate, they generate a large amount of heat, causing the internal temperature of the unit 1 to rise. Overheating of these components can lead to performance degradation and, in severe cases, burnout. Therefore, the unit 1 is sealed to prevent external dust and moisture from entering and affecting the internal electronic components. An air pump 12 is fixedly connected to the top of the unit 1. When heat dissipation is needed, the operator starts the air pump 12. The air pump 12 draws air from inside the unit 1, extracting the hot air. This hot air is then discharged from the air pump 12's outlet into the exhaust pipe 11 and then exits from the other end of the exhaust pipe 11. Since the water cover 10 contains water, the hot air exiting from the exhaust pipe 11 is cooled and contained within the water. The air passes through the water in the form of bubbles, allowing the water to absorb the heat from the hot air. The air then reaches the upper part of the water cover 10. As the air pump 12 continues to operate, the cooled air re-enters the interior of the machine body 1 through the through hole 13. A meltblown fabric 14 is fixedly connected to the inner wall of the through hole 13. The meltblown fabric 14 is a water-resistant but air-resistant material, allowing air to enter the interior of the machine body 1 while preventing water vapor in the water cover 10 from entering the interior of the machine body 1 and affecting the electronic components inside. This achieves the purpose of cooling the interior of the machine body 1 by circulating and cooling the hot air inside the machine body 1 when heat dissipation is needed, without allowing dust or water vapor to enter the interior of the machine body 1 and affect the electronic components inside.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
