Description

Technical Field

[0001] This invention relates to the field of electrical safety warning devices, specifically an electrical warning light. Background Technology

[0002] In the power transmission and distribution network, high-voltage power lines serve as the core carriers of electrical energy transmission and are widely distributed in various environments, including cities, rural areas, and mountainous regions. Because high-voltage power lines are typically erected at high heights and over wide areas, and some lines pass through areas of high population density or complex terrain, they are highly susceptible to safety accidents caused by external factors (such as accidental contact, vehicle collisions, or line sagging due to severe weather). These accidents can not only cause power outages but also endanger lives. Therefore, effective safety warnings for high-voltage power lines are crucial for ensuring the stable operation of the power system and the safety of the surrounding environment.

[0003] Currently, most power warning lights on the market are fixed installations, directly attached to utility poles or power lines using bolts, clamps, or other structures. This type of device has significant limitations during installation: firstly, for high-voltage power lines, traditional installation methods require manual climbing of the poles or the use of aerial work platforms, which is not only labor-intensive and inefficient but also poses safety risks such as electric shock and falls from heights; secondly, some warning lights rely on external power supplies, making it difficult to operate stably for extended periods in areas without power grid coverage, while battery-powered products require frequent battery replacements, resulting in high maintenance costs.

[0004] Regarding clamping stability, existing warning light clamp designs are mostly rigid or simple elastic structures. While rigid clamps can provide greater clamping force, they cannot adapt to cables of different diameters and are prone to loosening or even falling off the wire due to vibration, wind, or other factors. Simple elastic clamps (such as those driven directly by springs) suffer from uneven clamping force. As the spring deformation increases, the elastic force increases linearly, which may result in excessive clamping and damage to thin-diameter cables or insufficient clamping and stable fixation of thick-diameter cables, thus limiting their applicability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an electric warning light that solves the problems of inconvenient installation, low safety, unstable clamping, poor adaptability, reliance on external power supply, and high maintenance costs associated with traditional electric warning lights.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electric warning light, comprising a lower support base, a side support base fixedly installed on one side of the top of the lower support base, an upper support base fixedly installed on one side of the top of the side support base, a lower clamping seat above the lower support base, an upper clamping seat fixedly installed at the bottom of the upper support base, an audible and visual warning light fixedly installed at the bottom of the lower support base, a photovoltaic panel fixedly installed at the top of the upper support base, a crossbeam fixedly installed in the middle of the lower support base, a first chamber formed on both sides of the crossbeam, a rotating frame movably installed at both ends of the crossbeam, a spring plate fixedly installed on both sides of the first chamber, with the ends of the spring plates extending into the interior of the corresponding rotating frame, a connecting plate movably installed at the top of each rotating frame, a lifting plate movably installed at the end of each connecting plate, and the top of each lifting plate extending above the lower support base and fixedly installed at the bottom of the lower clamping seat.

[0007] Preferably, pressure rollers are fixedly installed on the inner top and inner side of the rotating frame, and the bottom ends of the pressure rollers abut against the upper surface of the spring plate on the corresponding side. A support platform is movably arranged in the middle of the first chamber, and the top two sides of the support platform abut against the lower surface of the spring plate on the corresponding side.

[0008] Preferably, a short shaft is movably installed on the inner wall of the inner end of the first chamber, and a threaded rod is fixedly installed on the outer end of each short shaft, with the outer diameter of the threaded rod threadedly connected to the middle of the support platform on the corresponding side.

[0009] Preferably, a second chamber is provided in the middle of the cross frame, the inner ends of the short shafts extend into the second chamber and are fixedly installed with driven bevel gears, the front end of the lower support is movably installed with a first internal hexagonal adjusting nut, the rear end of the first internal hexagonal adjusting nut is fixedly installed with an adjusting rod, the end of the adjusting rod extends into the second chamber and is fixedly installed with a driving bevel gear, and both ends of the driving bevel gear are meshed with the inner ends of the two driven bevel gears.

[0010] Preferably, a horizontal shaft is movably installed on the upper side of the inner side of the lower support base. A pull rope is fixedly installed on the outer diameter of the horizontal shaft, and the end of the pull rope extends to the top of the lower support base and is fixedly installed at the bottom center of the lower clamp. Ratchets are fixedly installed on both sides of the outer diameter of the horizontal shaft, and coil springs are fixedly installed on the outer diameter of the lower support base near the outer side of the ratchet.

[0011] Preferably, a central shaft is movably installed in the inner center of the side support seat, and a rotating plate is fixedly installed on the outer diameter of the central shaft. One end of the central shaft extends to the outside of the upper support seat and is fixedly installed with a second internal hexagonal adjusting nut. Limiting pins are movably installed in the inner part of the lower support seat near the ratchet. A first connecting rod is movably installed at one end of each limiting pin, and the end of each first connecting rod is movably installed on the bottom side of the rotating plate.

[0012] Preferably, a fixing plate is fixedly installed inside the upper support base, and an abutment rod is movably installed in the middle of the fixing plate. One side of the fixing plate is connected to the outer diameter of the abutment rod through a first return spring, and one end of the abutment rod is connected to the top side of the rotating plate through a second connecting rod.

[0013] Preferably, a trigger button is movably installed in the inner center of the upper clamp, the top of the trigger button extends into the interior of the upper support and is connected to the top wall of the upper support through a second return spring, and an insertion hole is provided in the center of the trigger button.

[0014] This invention provides an electrical warning light. It has the following beneficial effects: 1. This invention utilizes the elasticity of a spring plate to clamp the cable. The spring plate provides significant elasticity, ensuring more stable clamping and effectively mitigating the impact of external environmental factors (such as wind) on the device, preventing it from detaching from the cable. Simultaneously, during bending, the pressure rollers slide relative to the spring plate's surface, increasing the lever arm of the bent spring plate. This design compensates for the increased elasticity of the spring plate as the bending degree increases, thus maintaining uniform stored elasticity. Similarly, the elasticity remains uniform during release. This characteristic ensures that the clamping force of the lower clamp on the cable remains consistently uniform, guaranteeing clamping stability while minimizing clamping damage to the cable and extending its service life.

[0015] 2. In this invention, rotating the first internal hexagonal adjusting nut causes the adjusting rod and the driving bevel gear to rotate. The driving bevel gear further drives the driven bevel gears and the short shaft on both sides to rotate. The short shaft then drives the threaded rod to rotate. The rotating threaded rod causes the support platforms on both sides to move inward or outward synchronously. When the position of the support platform changes, the elastic force stored when the spring plate bends at the same angle will also change. This allows the device to adjust the clamping force according to cables of different diameters and materials, making it convenient to clamp various types of cables and expanding its applicability.

[0016] 3. During installation, the device can be delivered to the high-voltage power line using a drone or an insulating rod, eliminating the need for close manual contact with the power line and improving installation safety. The device automatically clamps and secures the cable upon contact with a trigger button. When the high-voltage power line contacts and compresses the trigger button, a series of linked mechanisms release the ratchet's restraint, releasing the spring force of the spring plate and causing the lower clamp to rise, thus clamping the cable. The entire installation process is highly automated, convenient, and efficient. Attached Figure Description

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below 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.

[0020] Example: Please see the appendix Figure 1 -Appendix Figure 6This invention provides a power warning light, such as... Figure 1 As shown, the device includes a lower support base 1, which serves as the bottom load-bearing structure, providing a stable support foundation for the entire device. Its interior can accommodate various transmission and control components, ensuring the orderly operation of each component during work. A side support base 2 is fixedly installed on one side of the top of the lower support base 1. The side support base 2 connects the lower support base 1 and the upper support base 3, serving as an intermediate support and connection. Simultaneously, it can house key components such as a central shaft, enabling force transmission and component rotation. An upper support base 3 is fixedly installed on one side of the top of the side support base 2. Located at the top of the device, the upper support base 3 is used to install components such as the upper clamp and photovoltaic panel, forming a clamping space for the cable in conjunction with the lower support base 1. Above the lower support base 1... A lower clamp 4 is provided, corresponding to the upper clamp 5, working together to clamp the cable. Its position is movable up and down. The clamping action on the cable is achieved through connection with components such as the lifting plate. The upper clamp 5 is fixedly installed at the bottom of the upper support 3, serving as the fixed end for clamping the cable. It cooperates with the movable lower clamp 4 to form a stable clamping structure. An audible and visual warning light 6 is fixedly installed at the bottom of the lower support 1. The audible and visual warning light 6 is the core component for realizing the warning function, emitting sound and light at night to alert surrounding personnel to the presence of high-voltage power lines. A photovoltaic panel 7 is fixedly installed at the top of the upper support 3. The photovoltaic panel 7 converts solar energy into electrical energy, providing power for the operation of the device. The power source, especially for the audible and visual warning lights 6, enables energy self-sufficiency. A crossbeam 8 is fixedly installed in the middle of the lower support base 1. The crossbeam 8 is installed inside the lower support base 1, providing space for the installation and support of components such as spring plates and rotating frames. It is an important structure for adjusting and transmitting clamping force. The crossbeam 8 has a first chamber 9 on both sides inside. The first chamber 9 provides space for components such as spring plates and support platforms, ensuring that these components can work normally. Rotating frames 10 are movably installed at both ends of the crossbeam 8. The rotating frames 10 can rotate around the ends of the crossbeam 8. Through their rotation, they drive the connecting plate and the lifting plate to move, thereby realizing the lifting and lowering of the lower clamp. Spring plates 11 are fixedly installed on both sides inside the first chamber 9, and springs... The ends of the plates 11 extend into the interior of the corresponding side rotating frame 10. The spring plates 11 are elastic and will be bent to store elastic force when the rotating frame rotates. When the elastic force is released, it can drive the rotating frame to return to the center, providing power for the lower clamp to rise. The top of the rotating frame 10 is movably mounted with a connecting plate 14. The connecting plate 14 serves to connect the rotating frame 10 and the lifting plate 15, converting the rotation of the rotating frame 10 into the up and down movement of the lifting plate 15. The ends of the connecting plates 14 are movably mounted with lifting plates 15. The lifting plates 15 connect the connecting plates 14 and the lower clamp 4. Under the drive of the connecting plates 14, they move up and down, thereby pushing the lower clamp 4 to rise to clamp the cable. The top of the lifting plates 15 extends above the lower support base 1 and is fixedly installed at the bottom of the lower clamp 4.

[0021] In this embodiment, pressure rollers 12 are fixedly installed on the inner top and inner side of the rotating frame 10, and the bottom ends of the pressure rollers 12 abut against the upper surface of the corresponding spring plate 11. The pressure rollers 12 roll on the upper surface of the spring plate 11 as the rotating frame 10 rotates, bending the spring plate 11 when the rotating frame 10 rotates. At the same time, their rolling characteristics can reduce frictional damage to the spring plate 11. A support platform 13 is movably arranged in the middle of the first chamber 9, and the top two sides of the support platform 13 abut against the lower surface of the corresponding spring plate 11. The support platform 13 supports the spring plate 11, and its position can be changed to adjust the stress state of the spring plate 11 when it bends, thereby changing the amount of elastic force stored in the spring plate 11.

[0022] Furthermore, short shafts 16 are movably installed on the inner wall of the inner end of the first chamber 9. The short shafts 16 can rotate on the inner wall of the first chamber 9 to provide support and power transmission for the rotation of the threaded rods 17. The outer ends of the short shafts 16 are fixedly installed with threaded rods 17, and the outer diameter of the threaded rods 17 is threaded to the middle of the corresponding side support platform 13. The threaded rods 17 rotate with the rotation of the short shafts 16, and drive the support platform 13 to move in the first chamber 9 through threaded transmission, thereby realizing the adjustment of the position of the support platform 13.

[0023] Furthermore, a second chamber 18 is provided in the middle of the cross frame 8. The second chamber 18 provides installation space for components such as the driving bevel gear and the driven bevel gear, ensuring normal meshing and transmission between the bevel gears. The inner ends of the short shaft 16 extend into the interior of the second chamber 18 and are fixedly installed with driven bevel gears 19. The driven bevel gears 19 mesh with the driving bevel gears 22, transmitting the rotational power of the driving bevel gears 22 to the short shaft 16. A first internal hexagonal adjusting nut 20 is movably installed at the front end of the lower support 1. The first internal hexagonal adjusting nut 20 can be rotated with an internal hexagonal wrench to adjust the rotation of the adjusting rod 21. The first internal hexagonal adjusting nut 20 is provided with a power input. An adjusting rod 21 is fixedly installed at the rear end of the first internal hexagonal adjusting nut 20. The adjusting rod 21 connects the first internal hexagonal adjusting nut 20 and the driving bevel gear 22, and transmits the rotation of the first internal hexagonal adjusting nut 20 to the driving bevel gear 22. The end of the adjusting rod 21 extends into the interior of the second chamber 18 and is fixedly installed with the driving bevel gear 22. The driving bevel gear 22 rotates under the drive of the adjusting rod 21. Through meshing with the driven bevel gear 19, it drives the driven bevel gears 19 on both sides to rotate synchronously. Both ends of the driving bevel gear 22 are meshed with the inner ends of the two driven bevel gears 19.

[0024] Furthermore, a horizontal shaft 26 is movably installed on the upper side of the lower support base 1. The horizontal shaft 26 can rotate within the lower support base 1, providing support for the winding and release of the pull rope 27. The pull rope 27 is fixedly installed on the outer diameter of the horizontal shaft 26, and the end of the pull rope 27 extends to the top of the lower support base 1 and is fixedly installed at the bottom center of the lower clamp 4. The pull rope 27 is wound or released when the horizontal shaft 26 rotates, thereby controlling the descent of the lower clamp 4. Ratchets 28 are fixedly installed on both outer diameters of the horizontal shaft 26. The ratchet 28 cooperates with the limiting pin 30 to limit the rotation direction of the horizontal shaft 26 and prevent the lower clamp 4 from rising during the preparation stage. Coil springs 29 are fixedly installed on the outer diameter of the lower support base 1 near the outer side of the ratchet 28. The coil springs 29 are elastic and store elastic force when the horizontal shaft 26 rotates. When the limiting pin 30 releases the restriction on the ratchet 28, the elastic force of the coil springs 29 can drive the horizontal shaft 26 to rotate in the opposite direction and release the pull rope 27.

[0025] Furthermore, a central shaft 23 is movably mounted in the inner center of the side support 2. The central shaft 23 can rotate within the side support 2, providing support for the rotation of the rotating plate 24. The rotating plate 24 is fixedly mounted on the outer diameter of the central shaft 23. The rotating plate 24 rotates with the rotation of the central shaft 23. Through its connection with the first connecting rod 31 and the second connecting rod 35, it drives the limit pin 30 and the abutment rod 33 to move. One end of the central shaft 23 extends to the outside of the upper support 3 and is fixedly mounted with a second internal hexagonal adjusting nut 25. The second internal hexagonal adjusting nut 25 can be adjusted by an internal hexagonal wrench. The hand rotation provides power input for the rotation of the central shaft 23. The lower support 1 has a limit pin 30 movably installed inside near the ratchet 28. The limit pin 30 can cooperate with the ratchet 28 to limit the rotation of the ratchet 28, thereby preventing the horizontal shaft 26 from rotating and the lower clamp 4 from rising. A first link 31 is movably installed at one end of the limit pin 30. The first link 31 connects the limit pin 30 and the rotating plate 24, converting the rotational motion of the rotating plate 24 into the movement of the limit pin 30. The end of the first link 31 is movably installed on the bottom side of the rotating plate 24.

[0026] Furthermore, a fixing plate 32 is fixedly installed inside the upper support base 3. The fixing plate 32 provides installation and support for the abutment rod 33 and the first return spring 34, ensuring that these components can work stably. The abutment rod 33 is movably installed in the middle of the fixing plate 32. The abutment rod 33 can move within the fixing plate 32, and its end can be inserted into the socket 38 of the trigger button 36 to limit the trigger button 36. One side of the fixing plate 32 is connected to the outer diameter of the abutment rod 33 through the first return spring 34. The first return spring 34 provides elastic force to the abutment rod 33. When the socket 38 of the trigger button 36 is aligned with the abutment rod 33, the first return spring 34 can push the abutment rod 33 into the socket 38. One end of the abutment rod 33 is connected to the top side of the rotating plate 24 through the second connecting rod 35. The second connecting rod 35 connects the abutment rod 33 and the rotating plate 24, converting the rotational movement of the rotating plate 24 into the movement of the abutment rod 33.

[0027] Furthermore, a trigger button 36 is movably installed in the middle of the upper clamping seat 5. The trigger button 36 can move up and down within the upper clamping seat 5. When it comes into contact with the cable, it is compressed, thereby triggering the subsequent clamping action. The top of the trigger button 36 extends into the interior of the upper support seat 3 and is connected to the top wall of the upper support seat 3 through a second return spring 37. The second return spring 37 provides a downward elastic force for the trigger button 36. During the preparation stage, the bottom end of the trigger button 36 is pushed out of the upper clamping seat 5. A socket 38 is provided in the middle of the trigger button 36. The socket 38 is used to accommodate the end of the abutment rod 33. When the abutment rod 33 is inserted into the socket 38, it can restrict the movement of the trigger button 36 and drive the rotating plate 24 to rotate, thereby releasing the restriction on the ratchet 28.

[0028] Working principle: During preparation, the lower clamp 4 is first pressed down. At this time, the coil spring 29 controls the horizontal shaft 26 to rotate, tightening the pull rope 27 and winding it around the horizontal shaft 26. Simultaneously, the lower clamp 4 drives the lifting plate 15 to descend. The lifting plate 15 drives the two rotating frames 10 to rotate via the connecting plate 14. When the rotating frames 10 rotate, they bend the spring plate 11 through the pressure roller 12. The bent spring plate 11 stores elasticity. Then, the second internal hexagonal adjusting nut 25 is rotated by the internal hexagonal wrench, driving the rotating plate 24 to rotate. When the rotating plate 24 rotates, the first connecting rod 31 on the lower side of the rotating plate 24 pushes the limit pin 30 to move inward, thereby locking the ratchet 28 and preventing the horizontal shaft 26 from rotating and the lower clamp 4 from rising. At the same time, the second connecting rod on the upper side of the rotating plate 24... Rod 35 pulls the abutment rod 33 to move, causing the abutment rod 33 to disengage from the socket 38. At this time, the second return spring 37 pushes the trigger button 36 downward, so that the bottom end of the trigger button 36 extends out of the bottom end of the upper clamp 5, and the overall structure of the device remains stable. During installation, the device is sent onto the high-voltage power line by a drone or an insulating rod, so that the middle part of the cable is located between the upper clamp 5 and the lower clamp 4. Then the control device descends, at which time the high-voltage power line contacts the trigger button 36 and compresses it inward. When the trigger button 36 is compressed and moves upward a distance, the end of the abutment rod 33 will be aligned with the socket 38. The first return spring 34 releases its elastic force, driving the abutment rod 33 to move and sending its end into the socket 38. During operation, the upper end of the rotating plate 24 rotates via the second connecting rod 35. The lower end of the rotating plate 24 rotates in the opposite direction via the central shaft 23, and the first connecting rod 31 pulls the limiting pin 30 outward, releasing its limiting effect on the ratchet 28. At this time, the horizontal shaft 26 can rotate normally, the elasticity of the bent spring plate 11 is released, the rotating frame 10 is returned to its original position, and the lower clamp 4 rises via the connecting plate 14 and the lifting plate 15, thereby clamping the cable and completing the device's fixing work. During the day, the photovoltaic panel 7 charges the cable, and at night, the audible and visual warning light 6 automatically illuminates to provide a warning. The spring plate 11 has a large elastic force when bent, making the clamping more stable. Simultaneously, when the spring plate 11 bends, the pressure roller 12 will... The relative sliding between the surfaces causes the lever arm of the bent spring plate 11 to increase, compensating for the increased elastic force of the spring plate 11 as the degree of bending increases. This keeps the stored elastic force uniform, and similarly, the elastic force remains uniform when released. This ensures that the clamping force of the lower clamp 4 on the cable remains uniform, guaranteeing clamping stability while reducing damage to the cable. Furthermore, rotating the first internal hexagonal adjusting nut 20 rotates the adjusting rod 21 and the driving bevel gear 22. The driving bevel gear 22 then rotates the driven bevel gears 19 and the short shaft 16 on both sides. The short shaft 16 rotates the threaded rod 17, and the rotating threaded rod 17 causes the support platforms 13 on both sides to move synchronously inward or outward. When the position of the support platform 13 changes...The spring force stored in the spring plate 11 changes when bent at the same angle, facilitating clamping of cables in different states and broadening its applicability.
