[0001] This invention relates to the field of line monitoring technology, and in particular to a power transmission line condition monitoring device based on power production. Background Technology
[0002] Overhead transmission lines are power lines that suspend conductors in the air using poles and insulators to transmit electrical energy over long distances. The main type of overhead transmission line is the open overhead line, which means that the transmission conductors are laid on the ground and fixed to upright poles and towers by insulators to transmit electrical energy from point A to point B, or even to other places further away.
[0003] To ensure the healthy operation of overhead transmission lines, condition monitoring methods are required to monitor and process multiple parameters of the overhead transmission lines. However, the current monitoring methods mostly rely on manual periodic monitoring. When conducting condition monitoring on relatively remote and unattended line sections, more manpower and resources are required, which is insufficient and results in high labor costs, making it not worthwhile.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.
[0030] Example 1, referring to Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides a power transmission line status monitoring device based on power production, including a pitch adjustment component on a protective frame 1, and a transmission component and a displacement component respectively. The transmission component and the displacement component are displaced on the power transmission line, and the status of the power transmission line is monitored by multiple sensing modules through the sensing module frame 26 on the pitch adjustment component.
[0031] Based on the load-bearing capacity of the power transmission line and the functional requirements of the device itself, the overall weight of the device is between 30kg and 45kg. It is neither too heavy, exceeding the load-bearing capacity of the power transmission line and causing it to break, nor too light, causing it to sway significantly on the power transmission line or even fall off due to external wind force.
[0032] Specifically, the pitch adjustment assembly also includes a pitch adjustment seat 21 with a main screw hole 22 fixed on the protective frame 1, and a pitch adjustment arm 23 with a secondary screw hole 24 sliding inside the pitch adjustment seat 21. The number of main screw holes 22 and secondary screw holes 24 are the same. The pitch adjustment arm 23 is fixed to the sensor module frame 26, and a positioning head 25 is internally threaded into one set of main screw holes 22 and secondary screw holes 24.
[0033] In use: Based on the current distance between the two transmission lines, pull the two adjusting arms 23 outward in advance, forcing them to move outward within the adjusting seat 21 until the sensor module frame 26 on the two adjusting arms 23 reaches the monitoring position of the two transmission lines. Then, screw the two positioning heads 25 into the main screw hole 22 and the auxiliary screw hole 24 respectively, tighten and position the adjusting seat 21 and adjusting arms 23 after the distance is adjusted, so as to realize the adaptive adjustment effect of the two sets of sensor module frames 26 following the distance of the transmission lines. It is suitable for monitoring scenarios of transmission lines with different distances.
[0034] Furthermore, the sensor module frame 26 is equipped with temperature sensors, sag sensors, and vibration sensors that monitor along the power transmission line. Through these sensors, the two power transmission lines can be monitored in a variety of ways, including temperature, sag, and vibration. Meanwhile, the current, voltage, and leakage of the power transmission lines are monitored by the base station, further increasing the diversity of power transmission line monitoring and ensuring the healthy operation of the power transmission lines.
[0035] A wireless transceiver 27 with an enhanced antenna is fixed on the protective frame 1. The wireless transceiver 27 wirelessly transmits the multi-parameters monitored by the two sets of sensor module frames 26 to the base station. It is suitable for monitoring scenarios in relatively remote, unattended transmission line sections, replacing traditional manual monitoring measures, which is faster and safer.
[0036] Specifically, the transmission assembly also includes a dual-head motor 31 embedded in the protective frame 1, and a first electric push rod 32 is fixed to one output shaft of the dual-head motor 31 via a coupling. A first main bevel gear 33 is fixed to the piston rod of the first electric push rod 32, and a first auxiliary bevel gear 34 is provided on the outer side of the first main bevel gear 33. The meshing stroke between the first main bevel gear 33 and the first auxiliary bevel gear 34 is adjusted to the correct position by the first electric push rod 32.
[0037] In use: First, control the first electric push rod 32 to open, and drive the first main bevel gear 33 to move forward to the meshing part of the first auxiliary bevel gear 34. Then, control the double-headed motor 31 to drive the first auxiliary bevel gear 34 to rotate forward or backward through the meshed first main bevel gear 33.
[0038] A drive spur gear 35 is sleeved on the first bevel gear 34 via a first concentric shaft. The displacement assembly also includes a differential spur gear 41 meshing on the outside of the drive spur gear 35. Double-headed electric push rods 42 rotate around the protective frame 1. One of the double-headed electric push rods 42 is sleeved with the differential spur gear 41, and a drive moving wheel 43 is fixed on the piston rod of the double-headed electric push rod 42. The distance between the drive moving wheels 43 is adaptively adjusted through the double-headed electric push rod 42.
[0039] The piston rods of the remaining three double-headed electric push rods 42 are fixed with driven moving wheels 44 that are synchronously driven with the drive moving wheel 43. Through these three double-headed electric push rods 42, the spacing of the three sets of driven moving wheels 44 is adaptively adjusted to ensure that the drive moving wheel 43 and the three sets of driven moving wheels 44 meet the current transmission line spacing requirements and can be stably driven on the transmission line.
[0040] Furthermore, the drive wheel 43 and the driven wheel 44 are provided with anti-slip grooves 45 for the contact transmission of the power line. The anti-slip grooves 45 increase the friction coefficient between the drive wheel 43 and the three sets of driven wheels 44 and the power line, preventing them from spinning and slipping on the power line.
[0041] In use: The first bevel gear 34, which rotates in either the forward or reverse direction, drives the drive moving wheels 43 on the two sets of differential gears 41 to rotate in the forward or reverse direction through the two sets of drive spur gears 35 on the first concentric shaft. The two sets of drive moving wheels 43 provide driving force, forcing the remaining three sets of driven moving wheels 44 to move back and forth on the two power transmission lines, thereby driving the protective frame 1 and its entirety to move back and forth along the two power transmission lines.
[0042] At the same time, the protective frame 1, which moves back and forth, drives two sets of sensor module frames 26 to carry out diverse monitoring operations on the entire transmission line, achieving the effect of freely switching between fixed-point monitoring and comprehensive monitoring, which is more flexible and convenient.
[0043] The first booster pipe frame 75 and the second booster pipe frame 94 are fixed diagonally on their outer sides, with limiting scrapers 13 that move along the power transmission line. Through the limiting scrapers 13, the first booster pipe frame 75 and the second booster pipe frame 94, which move back and forth with the protective frame 1, drive the limiting scrapers 13 to clean bird droppings, impurities, and ice on the power transmission line. At the same time, the limiting scrapers 13 also play a limiting transmission role in the back and forth movement of the protective frame 1 along the power transmission line by the driving moving wheel 43 and the three sets of driven moving wheels 44, thereby improving the stability of its displacement state and preventing it from being affected by the external environment, causing violent shaking or even falling.
[0044] Example 2, refer to Figures 1 to 7 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0045] Specifically, the piston cylinder 5 is equipped with a power-operating component and a purging component. The piston 66 on the power-operating component reciprocates within the piston cylinder 5, generating power pressure that is ejected through the first pressurizing tube frame 75 on the purging component. The first inspection camera 77 performs visual inspection of the status of a power transmission line.
[0046] Specifically, the power-operating component also includes a second electric push rod 61 fixed to another output shaft of the dual-head motor 31 via a coupling, and a second main bevel gear 62 is fixed on the piston rod of the second electric push rod 61. A second auxiliary bevel gear 63 is provided on the outer side of the second main bevel gear 62. The meshing stroke between the second main bevel gear 62 and the second auxiliary bevel gear 63 is adjusted to the correct position via the second electric push rod 61.
[0047] Furthermore, a cam 64 is sleeved on the second set of bevel gears 63 via a second concentric shaft, and the two sets of cams 64 are hinged to the piston 66 via connecting rods 65, and a four-way valve 67 is connected to the outer end of the piston cylinder 5.
[0048] In use: First, control the second electric push rod 61 to open, and drive the second main bevel gear 62 to move forward and engage with the second auxiliary bevel gear 63. Then the first electric push rod 32 and the second electric push rod 61 can be opened synchronously or independently. When opened synchronously, they can perform synchronous displacement and work. When opened independently, they can choose between displacement and work.
[0049] Then, the dual-head motor 31 is turned on, and the second main bevel gear 62, which is in position, drives the cam 64 to rotate continuously through the second concentric shaft on the second auxiliary bevel gear 63. The two sets of cams 64 drive the pistons 66 on the two connecting rods 65 to reciprocate in the two sets of piston cylinders 5, providing a stable gas supply for the subsequent cleaning and disposal measures of the power transmission line.
[0050] Specifically, the purging assembly also includes an air inlet head 71 connected to the bottom of the four-way valve 67. The protective frame 1 has an air inlet micro-hole directly below the air inlet head 71. Through the air inlet head 71, the air source is supplied to perform work on the return stroke of the two sets of pistons 66. The four-way valve 67 is connected to the first exhaust pipe 72. The boost pressure generated by the two sets of pistons 66 in the two sets of piston cylinders 5 is supplied into the two first exhaust pipes 72 through the two sets of four-way valves 67.
[0051] The inner ends of the two first exhaust pipes 72 are connected to a five-way valve 73, and the outer ends of the five-way valves 73 are connected to a first booster angle pipe 74. The bottom ends of the two first booster angle pipes 74 are connected to a first booster pipe rack 75, and the bottom end of the first booster pipe rack 75 is connected to an array of booster nozzles 76 for pre-cleaning the transmission line. The spacing between the two sets of booster nozzles 76 is distributed according to the spacing of the transmission line to meet the cleaning requirements of the transmission line after the spacing is adjusted.
[0052] In use: The pressurized gas supplied into the two first exhaust pipes 72 is sprayed onto the two transmission line areas through the two first booster angle pipes 74 on the five-way valve 73 and the booster nozzles 76 on the two sets of first booster pipe racks 75. This blows away and cleans the dust adhering to the transmission lines. In addition, the diagonally distributed limiting scrapers 13 on the two sets of first booster pipe racks 75 are used to scrape away bird droppings, impurities, and ice on the transmission lines. This provides convenience for the diverse monitoring work of the two sets of sensor module racks 26 and makes the monitoring more accurate.
[0053] Example 3, referring to Figures 1 to 7 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0054] Specifically, the protective frame 1 is also equipped with a transmission component and a treatment component. The pressurized air source is provided by the pressurization tank 82 on the transmission component and sprayed out through the second pressurization pipe rack 94 on the treatment component. The second inspection camera 96 performs visual inspection of the status of another transmission line.
[0055] Specifically, the transmission assembly also includes a second exhaust pipe 81 connected to the outer end of the four-way valve 67, and the outer end of the second exhaust pipe 81 is connected to the pressure tank 82. The pressurized gas generated in the two sets of piston cylinders 5 is supplied to the pressure tank 82 for temporary storage through the second exhaust pipe 81 on the two sets of four-way valves 67.
[0056] Two pressure sensors 12 are embedded in the two pressure tanks 82, and the pressure tanks 82 are respectively opened into a conduction chamber 83 and a pressure chamber 85 separated by a conduction partition 84. The pressure chamber 85 stores the pressurized gas supplied into the pressure tank 82, and the pressure sensor 12 monitors the pressure in the pressure chamber 85 in real time.
[0057] The pressurization chamber 85 inside the pressurization tank 82 is connected to a pressurization straight pipe 86, and a three-way valve 87 is connected to the pressurization straight pipe 86. The pressurized gas that reaches the pressurization chamber 85 is supplied to the two three-way valves 87 through the two pressurization straight pipes 86, so as to realize the reuse of the pressurized gas source.
[0058] The treatment components also include a small heater 91 and a small cooler 92 embedded in the pressurization tank 82 near the conduction chamber 83. Based on the parameter results of the power transmission line monitored by the temperature sensor, the small heater 91 and the small cooler 92 are controlled to turn on and deliver heat or cold source to the conduction chamber 83 in the pressurization tank 82. The heat or cold source is then conducted to the pressurization chamber 85 through the conduction baffle 84, so as to conduct heating or cooling treatment on the pressurized gas in the pressurization chamber 85.
[0059] Furthermore, the outer end of the three-way valve 87 is connected to a second pressure-boosting angle tube 93, the bottom ends of the two second pressure-boosting angle tubes 93 are connected to a second pressure-boosting tube frame 94, and the bottom end of the second pressure-boosting tube frame 94 is connected to an array of pressure-boosting nozzles 95 for power transmission line treatment. The spacing between the two sets of pressure-boosting nozzles 95 is distributed according to the spacing of the power transmission lines to meet the targeted treatment needs of the power transmission lines after the spacing is adjusted.
[0060] In use: The heat or cold source in the pressurization chamber 85 is transferred by heat or cold conduction, and simultaneously pressurized by the pressurized gas to the heat or cold source in the two three-way valves 87. The gas is then sprayed onto the two transmission lines through the two second pressurization angle pipes 93 and the pressurization nozzles 95 on the two sets of second pressurization pipe racks 94. Based on the monitoring parameters of the temperature sensor, the transmission lines are heated and de-iced or cooled down in a targeted manner to ensure the healthy operation of the transmission lines and prevent them from being too cold or too hot, which would cause power loss. This achieves the effect of timely handling after monitoring for excessively high or low temperatures.
[0061] Furthermore, both the first inspection camera 77 and the second inspection camera 96 are equipped with smoke sensors and open flame sensors. During the visual inspection of the two transmission lines, the first inspection camera 77 and the second inspection camera 96 also monitor the smoke and open flame of the two transmission lines, further increasing the diversity and comprehensiveness of the monitoring of the transmission lines.
[0062] The top of the three-way valve 87 is connected to the fire solenoid valve 10, and the top of the fire solenoid valve 10 is threadedly connected to the extinguishing agent tank 11, which is connected to the second pressurization pipe rack 94. The extinguishing agent tank 11 is pressurized and filled with insulating gas extinguishing agent, such as heptafluoropropane, IG541 or ultrafine water mist. This type of medium has high insulation strength and will not reduce the insulation distance between the conductor and the ground / phase to phase, thus avoiding flashover.
[0063] If dry powder must be used, a special electric fire extinguishing dry powder with high insulation level, extremely fine particles, and low sedimentation should be selected.
[0064] Based on the triple monitoring data consisting of smoke and open flame sensors in the first inspection camera 77 and the second inspection camera 96, combined with the temperature sensor, a triple detection method of flame + temperature + smoke is adopted, and a logical triggering mechanism is set between them to avoid false alarms from a single sensor and improve the safety of fire extinguishing agent use.
[0065] After the fire is visually detected by the first inspection camera 77 and the second inspection camera 96, there is a 3-5 second delay. The fire is then confirmed again by the triple monitoring system consisting of the smoke sensor, the open flame sensor, and the temperature sensor. Only then is the fire solenoid valve 10 opened. The fire solenoid valve 10 is a special automatic fire extinguishing valve for power transmission cables to prevent momentary interference that could cause the insulation extinguishing agent to be sprayed accidentally.
[0066] In the event of smoke or open flame, the wireless transceiver 27 immediately notifies the base station to send personnel to the scene. At the same time, the protective frame 1 is moved to the vicinity of the fire point, and the pressurized gas in the two sets of three-way valves 87 is used. At this time, the small heater 91 and the small cooler 92 are in the off state.
[0067] At the same time, the two sets of fire solenoid valves 10 automatically open, and under the pressure of the pressurized gas, the fire extinguishing agent in the two sets of fire extinguishing agent tanks 11 is sprayed through the two second pressurized angle pipes 93 and the pressurized nozzles 95 on the two sets of second pressurized pipe racks 94 to the fire point on the two power transmission lines for pre-extinguishing, controlling the fire, preventing its rapid spread, delaying the fire rescue, and achieving the effect of timely handling after smoke and open flame monitoring.
[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
