Description

Technical Field

[0001] This invention relates to the field of lightning strike counting technology, and more particularly to an intelligent lightning strike counter for disaster prevention. Background Technology

[0002] In the field of disaster prevention, lightning strikes pose a serious threat to people's lives and property due to their suddenness and destructive power. Accurately acquiring lightning strike data and recording and analyzing lightning waveforms in real time are crucial for in-depth research into lightning characteristics, developing effective lightning protection measures, and improving disaster prevention capabilities.

[0003] Traditional lightning strike counting devices mostly use a single electronic counter. While electronic counters can achieve relatively accurate counting, they are susceptible to external interference in complex electromagnetic environments, leading to counting errors or even failure. A single counting method cannot provide accurate and effective lightning strike data for disaster prevention. If the counting malfunctions, it may result in misjudgments of the number of lightning strikes, thus affecting subsequent lightning protection decisions. Furthermore, current methods typically only record the number of lightning strikes, not the lightning waveform. In areas with frequent and complex lightning activity, traditional recording methods cannot capture changes in lightning waveforms in real time and accurately, limiting the analysis of lightning characteristics and hindering the development of targeted lightning protection measures. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent lightning strike counter for disaster prevention.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An intelligent lightning strike counter for disaster prevention includes a cabinet. Inside the cabinet are a lightning current collector, an electromagnet, and an electronic counter. The lightning current collector is connected to the electromagnet. The electronic counter has a second contact. A mechanical counter is located on one inner wall of the cabinet, and a driving component that works with the electromagnet is located on the other inner wall. During a lightning strike, the electromagnet attracts and moves the driving component, triggering the mechanical and electronic counters to mechanically and electronically count the lightning strike. A lightning-attracting component connected to the lightning current collector is located on the outer wall of the cabinet. A device plate is fixed inside the cabinet. The upper end of the device plate has a first mounting slot and a second mounting slot. The first mounting slot contains a cooperating drawing component and an unwinding component. A drawing component is located at the upper end of the device plate. During a lightning strike, the drawing component draws a lightning waveform diagram on the drawing component. After the lightning strike, during the reset and movement of the drive component, the unwinding component is driven to operate, and the operation of the unwinding component drives the drawing component to unwind.

[0006] As a further improvement of the present invention, the drawing assembly includes an electromagnetic guide rail mounted on the upper end of the device plate, a guide rail seat provided on the electromagnetic guide rail, a first mounting block fixed to the upper end of the guide rail seat, a horizontally arranged first electromagnetic telescopic rod mounted on the side wall of the first mounting block, a second mounting block fixed to the telescopic end of the first electromagnetic telescopic rod, a vertically arranged second electromagnetic telescopic rod mounted to the lower end of the second mounting block, a pen cap fixed to the telescopic end of the second electromagnetic telescopic rod facing downward, and a drawing pen threadedly connected to the lower end of the pen cap.

[0007] As a further improvement of the present invention, the drive assembly includes two guide telescopic rods fixed to the inner wall of the cabinet. The telescopic ends of the two guide telescopic rods are fixed to the same movable plate. A tension spring is fitted on the outer side of each of the two guide telescopic rods. One end of the tension spring is fixed to the movable plate, and the other end of the tension spring is fixed to the inner wall of the cabinet. A magnetic absorbing plate and a pressure rod are fixed on the side wall of the movable plate away from the guide telescopic rods. The pressure rod is located above the magnetic absorbing plate and cooperates with a mechanical counter. A rack is fixed on the upper side wall of the pressure rod. The magnetic absorbing plate cooperates with an electromagnet. Two springs are fixed to the lower end of the movable plate. The ends of the two springs away from the movable plate are fixed to the same connecting plate. A first contact is fixed on the side wall of the connecting plate, and the first contact cooperates with a second contact.

[0008] As a further improvement of the present invention, the unwinding assembly includes two rotating shafts located inside the first mounting groove and arranged vertically. Both rotating shafts penetrate the inner wall of the first mounting groove and extend into the interior of the second mounting groove. Both rotating shafts are rotatably connected to the inner wall of the second mounting groove. Friction rollers are fixedly sleeved on the side walls of both rotating shafts in the first mounting groove. First gears are fixedly sleeved on the side walls of both rotating shafts in the second mounting groove. The two first gears mesh with each other. A second gear is mounted on the side wall of the lower rotating shaft through a one-way bearing. A through-hole is provided in the inner bottom wall of the second mounting groove. A third gear is rotatably installed inside the through-hole. The third gear meshes with the lower part of the second gear. The rack meshes with the lower part of the third gear.

[0009] As a further improvement of the present invention, the drawing assembly includes a rotating rod rotatably connected to the inner wall of the first mounting groove, a roll is fitted on the rotating rod, drawing paper is wound around the outer side of the roll, a fixing nut is threaded onto the rotating rod, and the drawing paper passes between two friction rollers.

[0010] As a further improvement of the present invention, a support plate is fixed on the inner wall of the first mounting groove, and the drawing paper is inserted into the inner side of the support plate.

[0011] As a further improvement of the present invention, the front of the device plate is provided with a collection groove located to the left of the first mounting groove, the inside of the collection groove is provided with a collection box, and a through groove communicating with the collection groove is provided through the inner wall of the first mounting groove, and the drawing paper is located inside the through groove.

[0012] As a further improvement of the present invention, a receiving groove is provided on the inner bottom wall of the through groove, and a cutting mechanism is provided inside the receiving groove. The cutting mechanism includes a cutter slidably disposed inside the receiving groove, and an electric push rod is installed on the inner bottom wall of the receiving groove. The telescopic end of the electric push rod is fixed to the lower side wall of the cutter.

[0013] As a further improvement of the present invention, the lightning attracting assembly includes a lightning rod connected to a lightning current collector, the lightning rod penetrating through the cabinet, a metal ball at the top of the lightning rod, and a lightning rod at the top of the metal ball.

[0014] The beneficial effects of this invention are: By setting up a linkage structure between the lightning current collector, electromagnet, electronic counter, and mechanical counter, the magnetic force generated by the electromagnet during a lightning strike attracts the magnetic plates in the drive component, thereby synchronously triggering the electronic and mechanical counters to perform dual counting of lightning strikes. The electronic counter achieves accurate electronic counting through the contact between the first and second contacts, while the mechanical counter achieves reliable mechanical counting through the direct pressing of the pressure rod. The two counting methods serve as backups for each other, effectively avoiding the failures or errors that may occur with a single counting method, significantly improving the accuracy and reliability of lightning strike counting, and ensuring that real and effective lightning strike data can be obtained in disaster prevention.

[0015] The drawing component uses an electromagnetic guide rail to drive the guide rail seat to move at a constant speed. Combined with the coordinated control of the first and second electromagnetic telescopic rods, the first electromagnetic telescopic rod adjusts the position of the second mounting block horizontally according to the magnitude of the lightning current, while the second electromagnetic telescopic rod controls the raising and lowering of the drawing pen according to the lightning current signal. This allows for the accurate drawing of waveforms on the drawing paper that correspond to the changes in lightning current intensity and time, achieving real-time visualization and recording of lightning waveforms. This provides intuitive data support for lightning analysis in disaster prevention.

[0016] Through the transmission design of rack and pinion with the third, second and first gears, the resetting action of the drive component is converted into the operating power of the unwinding component, which in turn drives the drawing paper in the drawing component to be automatically unwound, realizing the continuous supply of drawing paper after a lightning strike without manual intervention.

[0017] By setting up a cutting mechanism, the drawing paper is automatically cut after a single lightning strike is recorded. The cut portion of the drawing paper falls into a collection box through a trough for storage, avoiding the tedious operation of manual cutting. At the same time, it ensures the integrity and traceability of the drawing paper. The design of the collection box facilitates the subsequent organization and archiving of lightning record drawings, improving the standardization and convenience of disaster prevention data management.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] See Figures 1-9A smart lightning strike counter for disaster prevention includes a cabinet 1. Inside the cabinet 1 are a lightning current collector 14, an electromagnet 15, and an electronic counter 16. The lightning current collector 14 is connected to the electromagnet 15. The electronic counter 16 has a second contact 17. The lightning current collector 14 collects the current signal generated during a lightning strike. The electromagnet 15 generates magnetic force based on the signal from the lightning current collector 14. The electronic counter 16 electronically counts the number of lightning strikes. A mechanical counter 13 is installed on one inner wall of the cabinet 1 for mechanically counting the number of lightning strikes. The other inner wall of the cabinet 1... A drive assembly 2, which works in conjunction with an electromagnet 15, is installed on the wall. During a lightning strike, the electromagnet 15 attracts and moves the drive assembly 2. The drive assembly 2 triggers a mechanical counter 13 and an electronic counter 16 to mechanically and electronically count the lightning strikes. The drive assembly 2 includes two guide telescopic rods 205 fixed to the inner wall of the cabinet 1. The telescopic ends of the two guide telescopic rods 205 are fixed to the same moving plate 201. The guide telescopic rods 205 restrict the moving plate 201 to move only in a straight line. A tension spring 206 is fitted onto the outer side of each guide telescopic rod 205, with one end of the tension spring 206 fixed to the moving plate 201. On the upper part, the other end of the tension spring 206 is fixed to the inner wall of the cabinet 1. The tension spring 206 is used to drive the movable plate 201 to reset. A magnetic absorbing piece 202 and a pressure rod 203 are fixed on the side wall of the movable plate 201 away from the guide telescopic rod 205. The pressure rod 203 is located above the magnetic absorbing piece 202. The magnetic absorbing piece 202 cooperates with the electromagnet 15 to realize the attraction and movement of the movable plate 201. The pressure rod 203 cooperates with the mechanical counter 13. The pressure rod 203 is used to trigger the mechanical counter 13 to count. A rack 204 is fixed on the upper side wall of the pressure rod 203. The magnetic absorbing piece 202 cooperates with the electromagnet 15 to move the movable plate 201. Two springs 207 are fixed at the lower end. The ends of the two springs 207 away from the moving plate 201 are fixed to the same connecting plate 208. A first contact 209 is fixed on the side wall of the connecting plate 208. The first contact 209 cooperates with the second contact 17. By setting the springs 207, an elastic connection is achieved between the connecting plate 208 and the moving plate 201. This prevents the first contact 209 from being damaged by hard impact when it comes into contact with the second contact 17. When the first contact 209 comes into contact with the second contact 17, the electronic counter 16 performs electronic counting.

[0022] The outer wall of the cabinet 1 is provided with a lightning attracting assembly 3 connected to the lightning current collector 14. The lightning attracting assembly 3 is used to guide lightning to the lightning current collector 14. The lightning attracting assembly 3 includes a lightning attracting rod 301 connected to the lightning current collector 14. The lightning attracting rod 301 passes through the cabinet 1. The top of the lightning attracting rod 301 is provided with a metal ball 302. The metal ball 302 is used to increase the lightning attracting area. The top of the metal ball 302 is provided with a lightning rod 303. The lightning rod 303 is used to further guide the lightning.

[0023] The cabinet 1 has a fixed device plate 7 inside. The upper end of the device plate 7 is provided with a first mounting groove 11 and a second mounting groove 18. The first mounting groove 11 is provided with a matching drawing assembly 6 and an unwinding assembly 5. The unwinding assembly 5 includes two rotating shafts 502 located inside the first mounting groove 11 and arranged vertically. Both rotating shafts 502 pass through the inner wall of the first mounting groove 11 and extend into the interior of the second mounting groove 18. Both rotating shafts 502 are rotatably connected to the inner wall of the second mounting groove 18. Friction rollers 501 are fixedly sleeved on the side walls of the two rotating shafts 502 inside the first mounting groove 11. The rotating shafts 502 are used to support and drive the friction rollers 501 to rotate. The friction rollers 501 are used to rub and drive the drawing paper 604 to move. A first gear 503 is fixedly sleeved on the side wall of the second mounting groove 18. The two first gears 503 mesh with each other and are used to realize the synchronous reverse rotation of the two rotating shafts 502. A second gear 504 is sleeved on the side wall of the lower rotating shaft 502 through a one-way bearing 505. The one-way bearing 505 makes the second gear 504 drive the rotating shaft 502 to rotate in only one direction. A through-hole 19 is provided through the inner bottom wall of the second mounting groove 18. A third gear 506 is rotatably installed inside the through-hole 19. The third gear 506 meshes below the second gear 504. The rack 204 meshes below the third gear 506. The third gear 506 is used to transmit the driving force of the rack 204 to the second gear 504.

[0024] See Figure 4The upper end of the device plate 7 is provided with a drawing component 4, which is used to draw lightning waveform diagrams on drawing paper 604. The drawing component 4 includes an electromagnetic rail 401 mounted on the upper end of the device plate 7, and a rail seat 402 is provided on the electromagnetic rail 401. The electromagnetic rail 401 is electrically connected to the lightning current collector 14 and is activated according to the signal from the lightning current collector 14, driving the rail seat 402 to move at a constant speed along the electromagnetic rail 401. When there is no signal from the lightning current collector 14, the electromagnetic rail 401 stops, and the rail seat 402 automatically moves and resets. A first mounting block 403 is fixed to the upper end of the rail seat 402. A horizontally arranged first electromagnetic telescopic rod 404 is mounted on the side wall of the first mounting block 403, and a second mounting block 405 is fixed to the telescopic end of the first electromagnetic telescopic rod 404. The first electromagnetic telescopic rod 404 is used to drive the second mounting block 405 to move horizontally. The first electromagnetic telescopic rod 404 is electrically connected to the lightning current collector 14. The magnitude of the lightning current is positively correlated with the telescopic length of the first electromagnetic telescopic rod 404. The lower end of the second mounting block 405 is equipped with a vertically arranged second electromagnetic telescopic rod 406. The second electromagnetic telescopic rod 406 is electrically connected to the lightning current collector 14. It is activated according to the signal of the lightning current collector 14. The second electromagnetic telescopic rod 406 extends, driving the drawing pen 408 to move down and contact the drawing paper 604. The telescopic end of the second electromagnetic telescopic rod 406 faces downward and is fixed with a pen sleeve 407. The lower end of the pen sleeve 407 is threadedly connected to the drawing pen 408. When lightning strikes, the lightning waveform diagram is drawn on the drawing paper assembly 6 through the drawing assembly 4.

[0025] After the lightning strike, during the reset and movement of the drive component 2, the unwinding component 5 is driven to operate, and the operation of the unwinding component 5 drives the drawing component 6 to unwind.

[0026] See Figure 8 The drawing assembly 6 includes a rotating rod 601 rotatably connected to the inner wall of the first mounting groove 11. A roll 603 is fitted on the rotating rod 601. Drawing paper 604 is wound around the outer side of the roll 603. The drawing paper 604 is used to record lightning waveform diagrams. A fixing nut 602 is threaded onto the rotating rod 601. The drawing paper 604 passes between two friction rollers 501.

[0027] See Figure 7 A support plate 12 is fixed on the inner wall of the first mounting groove 11. The drawing paper 604 is inserted into the inner side of the support plate 12. The support plate 12 is used to support and restrict the drawing paper 604 so that the drawing paper 604 remains flat.

[0028] See Figure 4The front of the device plate 7 is provided with a collection groove 8 located on the left side of the first mounting groove 11. The inside of the collection groove 8 is a collection box 9, which is used to store the drawing paper 604. The inner wall of the first mounting groove 11 is provided with a through groove 20 that communicates with the collection groove 8. The drawing paper 604 is located inside the through groove 20.

[0029] See Figure 9 A receiving groove is provided on the inner bottom wall of the groove 20. A cutting mechanism is provided inside the receiving groove. The cutting mechanism is used to cut the drawing paper 604. The cutting mechanism includes a cutter 22 that is slidably disposed inside the receiving groove. The cutter 22 is used to actually cut the drawing paper 604. An electric push rod 21 is installed on the inner bottom wall of the receiving groove. The telescopic end of the electric push rod 21 is fixed to the lower side wall of the cutter 22. The electric push rod 21 is used to drive the cutter 22 to move.

[0030] When this invention is used, when lightning occurs, the lightning rod 301 in the lightning attracting assembly 3 penetrates the cabinet 1, and the metal ball 302 at its top increases the lightning attracting area. The lightning rod 303 at the top of the metal ball 302 further guides the lightning to the lightning current collector 14. The lightning current collector 14 collects the current signal generated when the lightning strikes. The electromagnet 15 generates magnetic force according to the signal of the lightning current collector 14. The magnetic suction plate 202 cooperates with the electromagnet 15 to attract the moving plate 201 and move it toward the electromagnet 15. The moving plate 201 moves in a straight line under the restriction of the two guide telescopic rods 205, while stretching the two tension springs 206. When the movable plate 201 moves, the pressure rod 203 on it triggers the mechanical counter 13 to perform mechanical counting. The first contact 209 below the movable plate 201 contacts the second contact 17 under the elastic connection of the spring 207 to realize the electronic counter 16 to perform electronic counting. The rack 204 fixed on the upper side wall of the pressure rod 203 will drive the third gear 506 to rotate as the movable plate 201 moves. The third gear 506 drives the second gear 504 to rotate. However, due to the one-way transmission characteristic of the one-way bearing 505, the second gear 504 will not drive the lower rotating shaft 502 to rotate at this time. The electromagnetic rail 401 in the drawing component 4 is activated according to the signal of the lightning current collector 14 and drives the rail base 402 to move at a constant speed along the electromagnetic rail 401. The first electromagnetic telescopic rod 404 on the side wall of the first mounting block 403 on the rail base 402 extends and retracts according to the magnitude of the lightning current, causing the second mounting block 405 to move horizontally. The second electromagnetic telescopic rod 406 at the lower end of the second mounting block 405 is activated according to the signal of the lightning current collector 14 and extends, causing the pen cap 407 to move down. The drawing pen 408 contacts the drawing paper 604 and draws a lightning waveform diagram that displays the magnitude and duration of the lightning current during the movement. When the lightning strike ends, the electromagnet 15 loses its magnetic force, the drawing assembly 4 stops drawing and moves to reset. The two tension springs 206 drive the moving plate 201 to reset. When the moving plate 201 resets, the rack 204 moves in the opposite direction, causing the third gear 506 to rotate in the opposite direction. The third gear 506 drives the second gear 504 to rotate. At this time, the second gear 504 drives the lower rotating shaft 502 to rotate using the one-way bearing 505. The two first gears 503 can drive the two rotating shafts 502 to rotate in opposite directions synchronously. The friction rollers 501 on the two rotating shafts 502 rub and drive the drawing paper 604 to continue moving, thereby moving the drawing paper 604 with the lightning waveform diagram into the collection box 9 in the collection trough 8, and enabling a new section of drawing paper 604 to move above the support plate 12. Then, the electric push rod 21 is activated to drive the cutter 22 to move upward and cut the drawing paper 604. The cut part of the drawing paper 604 falls into the collection box 9 in the collection slot 8 through the slot 20 and is stored there.

[0031] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
