Description

Technical Field

[0001] This invention relates to the field of power grid maintenance technology, specifically to a lidar device for monitoring the icing thickness of transmission lines. Background Technology

[0002] Monitoring the icing thickness of transmission lines involves using technologies such as lidar, image recognition, and tension sensing to collect data in real time on the geometric dimensions, weight, and ambient temperature and humidity of icing on transmission conductors, insulator strings, and other parts. After analysis and calculation, the icing thickness, density, and growth trend are obtained, providing timely warnings of risks such as excessive icing and ice flashover. This power-specific monitoring technology supports de-icing decisions and operation and maintenance scheduling, and can effectively prevent ice disasters such as tower collapse, line breakage, and line galloping.

[0003] Existing icing monitoring methods mostly use image recognition or tension sensors to collect data at fixed points, which can only passively reflect the icing status and cannot actively remove ice. Maintenance personnel need to go to the site to confirm before starting the de-icing process, resulting in a strong response lag and difficulty in stopping the icing growth trend in a timely manner. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a lidar icing thickness monitoring device for power transmission lines, which solves the problem of strong response lag and difficulty in timely blocking the icing growth trend.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser radar icing thickness monitoring device for power transmission lines, comprising a detection plate one, a detection plate two attached to the lower surface of the detection plate one, multiple buckles fixedly disposed on the outer walls of the detection plate one and the detection plate two, a power transmission line sleeved inside the buckles, and a fixing frame fixedly connected to the outer wall of the power transmission line, a laser detector fixedly disposed on the outer wall of the detection plate one, multiple fixing rings fixedly connected to the outer walls of the detection plate one and the detection plate two, an air inlet duct fixedly connected inside the fixing frame, a rotating plate rotatably connected inside the air inlet duct, multiple sleeve rods mounted on the outer wall of the rotating plate, and multiple iron rings fixedly disposed inside the sleeve rods, the outer wall of the sleeve rods rotatably connected to the inside of the air inlet duct, and an oscillation component fixedly connected to the end of the sleeve rod away from the rotating plate.

[0006] The above technical solution involves the operation of an oscillating component that runs synchronously with an oscillating component of the same specification on a nearby tower. This creates resonance, thereby effectively removing floating snow and ice from the surface of the transmission line and significantly reducing the probability of ice and snow adhesion.

[0007] Preferably, the oscillation assembly includes a rotating column, the outer wall of which is fixedly connected to the end of the sleeve rod away from the rotating plate, and a plurality of striking balls are slidably connected inside the rotating column.

[0008] Preferably, the rotating plate is equipped with multiple adsorption components. Each adsorption component includes a magnetic block one, which is magnetically attracted to an iron ring inside the sleeve rod. A magnetic block two is attached to the outer wall of the sleeve rod, and the outer wall of the magnetic block two is fixedly connected to the inside of the air inlet duct. The magnetic blocks one and two are magnetically repelled on opposite sides.

[0009] Preferably, the adsorption assembly further includes a fixing column, and a sliding rod is slidably connected inside the fixing column. One end of the sliding rod is fixedly connected to the side of the magnetic block away from the sleeve rod, and an elastic element is fixedly provided at the other end of the sliding rod.

[0010] Preferably, a cross is fixedly connected inside the detection plate, and an auxiliary component is fixedly disposed inside the cross. The auxiliary component includes a baffle, and the outer wall of the baffle is fixedly disposed on the outer wall of the fixing frame.

[0011] Preferably, the auxiliary component further includes a rotating shaft, the outer wall of which is rotatably connected to the inside of the cross, a fan blade is fixedly connected to the outer wall of the rotating shaft, a cleaning plate is fixedly connected to the end of the rotating shaft away from the cross, and the outer wall of the cleaning plate is attached to the outer wall of the baffle near the fixing frame.

[0012] Preferably, an air-gathering pipe is fixedly connected inside the air inlet duct, and the air-gathering pipe is used to increase the gas flow rate in the air inlet duct.

[0013] Preferably, the fixing frame has multiple grooves inside, and the size of the grooves is adapted to the external power transmission line.

[0014] Preferably, the buckle is internally equipped with multiple ball bearings to reduce friction between the buckle and the external power transmission line.

[0015] Preferably, the outer wall of the fixed column is fixedly connected to the inside of the rotating plate, and the end of the elastic element away from the sliding rod is fixedly disposed inside the fixed column.

[0016] The above technical solution involves splicing detection plate one and detection plate two together, and then fixing them to the outside of the transmission line with clips. The laser detector can scan the ice and snow accumulation on the transmission line in real time and upload the data to the central control terminal. The fixing frame is installed at the connection between the tower and the transmission line. When the high-altitude airflow enters the air inlet, it drives the rotating plate to rotate. The rotating plate drives the sleeve rod to rotate through the adsorption component, which in turn triggers the oscillation component to work. If the oscillation components of the same specification on the adjacent towers operate synchronously, resonance can be formed, thereby achieving the effect of efficiently removing the floating snow and ice layer on the surface of the transmission line and greatly reducing the probability of ice and snow adhesion.

[0017] This invention provides a lidar device for monitoring the icing thickness of power transmission lines. It has the following advantages: 1. This invention uses a rotating plate to drive the sleeve rod to rotate via an adsorption component, thereby triggering the operation of the oscillation component. If oscillation components of the same specification on adjacent towers operate synchronously, resonance can be formed, thereby achieving the effect of efficiently removing floating snow and ice layers from the surface of transmission lines, timely blocking the growth trend of icing, and significantly reducing the probability of ice and snow adhesion.

[0018] 2. This invention uses an adsorption component to drive the sleeve rod to rotate intermittently, thereby avoiding the continuous operation of the oscillation component when the rotating plate rotates, which would cause long-term high-frequency oscillation, loosening of external connections, and affecting the normal operation of the power transmission line.

[0019] 3. The present invention achieves real-time cleaning of the baffle by synchronously rotating the cleaning plate on the outer wall of the side of the baffle close to the fixed frame, thereby preventing external wind and snow from adhering to the surface of the baffle and causing snow to accumulate and freeze, thus affecting the normal entry of external wind and ensuring the normal and stable operation of the fixed frame and its internal components.

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0023] Please see the appendix Figure 1 -Appendix Figure 4 This invention provides a lidar icing thickness monitoring device for power transmission lines, comprising a detection plate 1, a detection plate 2 attached to the lower surface of the detection plate 1, multiple buckles 3 fixedly disposed on the outer walls of the detection plate 1 and the detection plate 2, a power transmission line sleeved inside the buckles 3, and a fixing frame 6 fixedly connected to the outer wall of the power transmission line, a laser detector 4 fixedly disposed on the outer wall of the detection plate 1, multiple fixing rings 5 ​​fixedly connected to the outer walls of the detection plate 1 and the detection plate 2, an air inlet duct 9 fixedly connected inside the fixing frame 6, a rotating plate 11 rotatably connected inside the air inlet duct 9, multiple sleeve rods 13 mounted on the outer wall of the rotating plate 11, and multiple iron rings fixedly disposed inside the sleeve rods 13, the outer wall of the sleeve rods 13 rotatably connected to the inside of the air inlet duct 9, and an oscillation component 15 fixedly connected to the end of the sleeve rods 13 away from the rotating plate 11.

[0024] Specifically, the detection plate 1 and detection plate 2 are first spliced ​​together and then fixed to the outside of the transmission line by the buckle 3. The laser detector 4 is used to scan the snow and ice accumulation on the outside of the transmission line in real time and transmit the monitored data to the external main control equipment in real time. The fixing frame 6 is installed on the side of the interface between the external tower and the transmission line. When it is at high altitude, the outside wind flows into the air inlet duct 9, which further drives the rotating plate 11 to rotate. When the rotating plate 11 rotates, it drives the sleeve rod 13 to rotate inside the air inlet duct 9 through the adsorption component 12, which further drives the oscillation component 15 to work. At this time, when the oscillation component 15 and the same specification oscillation component 15 installed on the outside of the adjacent tower are in a synchronous working state, resonance is formed, thereby achieving efficient removal of the floating snow and ice layer attached to the outside of the transmission line and greatly reducing the probability of ice and snow adhesion.

[0025] Please see the appendix Figure 5 and attached Figure 7 The oscillation assembly 15 includes a rotating column 151. The outer wall of the rotating column 151 is fixedly connected to the end of the sleeve rod 13 away from the rotating plate 11. Multiple striking balls 152 are slidably connected inside the rotating column 151.

[0026] Specifically, when the sleeve 13 rotates, the fixed action of the sleeve 13 and the rotating column 151 drives the rotating column 151 to rotate synchronously, which in turn drives the multiple striking balls 152 inside to slide up and down and collide with the rotating column 151 to generate vibration.

[0027] Please see the appendix Figure 4 -Appendix Figure 6 The rotating plate 11 is equipped with multiple adsorption components 12. Each adsorption component 12 includes a magnetic block 123. The magnetic block 123 is magnetically attracted to the iron ring inside the sleeve rod 13. A magnetic block 2 14 is attached to the outer wall of the sleeve rod 13. The outer wall of the magnetic block 2 14 is fixedly connected to the inside of the air inlet duct 9. The magnetic blocks 123 and 14 repel each other on opposite sides. The adsorption component 12 also includes a fixing column 121. A sliding rod 122 is slidably connected inside the fixing column 121. One end of the sliding rod 122 is fixedly connected to the side of the magnetic block 123 away from the sleeve rod 13. An elastic element 124 is fixedly provided at the other end of the sliding rod 122.

[0028] Specifically, when the rotating plate 11 rotates, the fixing action of the rotating plate 11 and the fixed column 121 will drive the fixed column 121 to rotate, which in turn will drive the sliding rod 122, the magnetic block 123 and the elastic element 124 inside to rotate synchronously. When the magnetic block 123 rotates for a period of time and is at the same horizontal line as the iron ring installed inside the sleeve rod 13, the magnetic block 123 will attract the iron ring, which will further drive the sliding rod 122 to slide inside the fixed column 121. At the same time, it will cooperate with the fixed column 121 to stretch the elastic element 124. The elastic element 124 can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc., preferably a coil spring. The spring further drives the sleeve rod 13 to rotate synchronously. Then, the first magnetic block 123 continues to rotate. When the first magnetic block 123 rotates and is on the same horizontal line as the second magnetic block 14, the magnetic repulsion between the opposite sides of the first magnetic block 123 and the second magnetic block 14 further causes the first magnetic block 123 to detach from the iron ring. The elastic element 124 releases its own elastic force to reset the sliding rod 122 and the first magnetic block 123. The sleeve rod 13 is driven to rotate intermittently through the adsorption component 12, thereby avoiding the continuous operation of the oscillation component 15 when the rotating plate 11 rotates, which would cause long-term high-frequency oscillation, loosening of external connections, and affecting the normal operation of the power transmission line.

[0029] Please see the appendix Figure 3 -Appendix Figure 4The detection plate 1 has a cross 8 fixedly connected inside, and an auxiliary component 7 is fixedly installed inside the cross 8. The auxiliary component 7 includes a baffle 71, the outer wall of which is fixedly installed on the outer wall of the fixed frame 6. The auxiliary component 7 also includes a rotating shaft 73, the outer wall of which is rotatably connected to the inside of the cross 8. A fan blade 74 is fixedly connected to the outer wall of the rotating shaft 73. A cleaning plate 72 is fixedly connected to the end of the rotating shaft 73 away from the cross 8. The outer wall of the cleaning plate 72 is attached to the outer wall of the baffle 71 near the fixed frame 6. An air-gathering pipe 10 is fixedly connected inside the air inlet duct 9. The air-gathering pipe 10 is used to increase the gas flow rate in the air inlet duct 9. The fixed frame 6 has multiple grooves inside, and the size of the grooves is adapted to the external power transmission line. Multiple balls are installed inside the buckle 3 to reduce the friction between the buckle 3 and the external power transmission line. The outer wall of the fixed column 121 is fixedly connected to the inside of the rotating plate 11. The end of the elastic element 124 away from the sliding rod 122 is fixedly installed inside the fixed column 121.

[0030] Specifically, when outside wind enters the air inlet duct 9, it will drive the fan blades 74 to rotate, which in turn drives the rotating shaft 73 to rotate inside the cross 8. When the rotating shaft 73 rotates, through the fixing action of the rotating shaft 73 and the cleaning plate 72, the cleaning plate 72 will be driven to rotate synchronously on the outer wall of the baffle 71 near the fixing frame 6, thereby achieving real-time cleaning of the baffle 71, preventing outside wind and snow from adhering to the surface of the baffle 71, causing snow to accumulate and freeze, affecting the normal entry of outside wind, and ensuring the normal and stable operation of the fixing frame 6 and its internal components.

[0031] Workflow: When the rotating plate 11 rotates, it drives the fixed column 121 to rotate synchronously, which in turn drives the sliding rod 122, the first magnetic block 123, and the elastic element 124 inside to rotate together. When the first magnetic block 123 rotates to be flush with the iron ring inside the sleeve rod 13, the two are magnetically attracted to each other, which further drives the sliding rod 122 to slide inside the fixed column 121. At the same time, the elastic element 124 is stretched, which further drives the sleeve rod 13 to rotate. Then the first magnetic block 123 continues to rotate. When it rotates to be flush with the second magnetic block 14, the magnetic repulsion of their opposite sides further causes the first magnetic block 123 to detach from the iron ring. At this time, the elastic element 124 rebounds, causing the sliding rod 122 and the first magnetic block 123 to reset. The sleeve rod 13 is driven to rotate intermittently through the adsorption component 12, thereby avoiding the continuous operation of the oscillation component 15 driven by the rotating plate 11, preventing the connection structure from loosening due to long-term high-frequency oscillation, and affecting the normal operation of the power transmission line.

[0032] When outside wind enters the air intake duct 9, it will simultaneously blow the fan blades 74 to rotate, which will further drive the rotating shaft 73 to rotate inside the cross 8. When the rotating shaft 73 rotates, it will drive the cleaning plate 72 to rotate synchronously along the outer wall of the baffle 71 near the fixed frame 6, thereby achieving real-time cleaning of snow on the surface of the baffle 71, preventing snow from accumulating and freezing to block the air intake channel, and ensuring the stable operation of the fixed frame 6 and its internal components.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
