Description

Technical Field

[0001] This invention relates to the field of lightning protection technology for high-lift rotating mechanisms, and more particularly to a lightning protection system for a high-lift rotating structure. Background Technology

[0002] High-lift rotating structures, when operating outdoors, are typically located at high altitudes or in open areas, making them high-risk targets for lightning strikes due to their height and equipment characteristics. Strict lightning protection measures are crucial for ensuring structural safety, equipment stability, and the safety of personnel. Lightning rods neutralize charges in clouds through the tip discharge effect, protecting surrounding objects from lightning strikes. However, in rotating structures, the position and orientation of the lightning rod are constantly changing, easily leading to unstable discharge paths and ineffective charge neutralization. Simultaneously, cables in high-lift rotating structures may become entangled, stretched, or broken due to the lifting or rotating motion, resulting in unstable grounding, unreliable conduction of lightning current, and increased lightning strike risk. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a lightning protection system with a high-lift rotating structure, which addresses the shortcomings of the prior art.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A lightning protection system with a high-lift rotating structure includes: a lightning arrester, an upper down conductor, a lightning discharge ring, a rotating structure, a cable storage device, a lifting mechanism, a lower down conductor, and a grounding device. The rotating structure is connected to the lifting mechanism, the lightning arrester is connected to the rotating structure, the lightning arrester is electrically connected to the lightning discharge ring through the upper down conductor, the lightning discharge ring is installed in the rotating structure, the two ends of the lower down conductor are electrically connected to the lightning discharge ring and the grounding device respectively, and the middle part of the lower down conductor is disposed in the cable storage device.

[0005] The beneficial effects of adopting the technical solution of this invention are that by installing a lightning arrester on the top of the high-lift rotating structure, a complete lightning conduction channel is formed through a lightning discharge ring, down conductor, and grounding device, ensuring that the lightning current can be quickly discharged to the ground. The down conductor adopts a cable storage device, which can realize the synchronous lifting and lowering movement of the cable with the lifting structure, fully adapting to the needs of the high-lift structure.

[0006] Furthermore, the rotating structure is provided with a rotating part and a stationary part. The stationary part is connected to the lifting mechanism, the rotating part is rotatably connected to the stationary part, the lightning arrester is connected to the rotating part, and the lightning discharge ring is disposed between the rotating part and the stationary part.

[0007] The beneficial effect of adopting the above-mentioned further technical solution is that the lightning discharge ring is installed between the rotating part and the stationary part of the rotating structure for the transmission of lightning current during rotation. This effectively solves the reliability problem of lightning current transmission during rotation.

[0008] Furthermore, the lightning protection ring includes: a rotating shaft, a lightning protection ring body, brush filaments, stator conductors, and rotor conductors. The rotating shaft is connected to the lightning protection ring body. The brush filaments and the rotor conductors are both electrically connected to the lightning protection ring body. The stator conductors are electrically connected to the brush filaments. The upper lead wire is electrically connected to the rotor conductors, and the lower lead wire is electrically connected to the stator conductors.

[0009] The beneficial effects of adopting the above-mentioned further technical solutions are that the lightning discharge ring is used for the transmission of lightning current between the rotating part and the stationary part. The whole is insulated from the shell and can withstand instantaneous current of more than 200kA or transient voltage of more than 100kV. It can realize the reliable transmission of lightning current from the high-speed rotating mechanism to the ground and is suitable for various rotating structures.

[0010] Furthermore, the brush bristles are bundled brush bristles, which include multiple parallel silver-copper-nickel alloy wires; the lightning discharge ring body is a cylindrical conductive ring, and a conductive ring circumferential surface is provided on the lightning discharge ring body; the brush bristles and the rotor wire are all slidably electrically connected to the conductive ring circumferential surface.

[0011] The beneficial effect of adopting the above-mentioned further technical solution is that the brush bristles use multiple parallel current-carrying wires to realize the transmission of lightning current. Each bundle of brush bristles is composed of multiple silver-copper-nickel alloy wires. This design increases the contact area and can realize the safe transmission of lightning current.

[0012] Furthermore, the cable storage device is a cable storage device based on a pulley system.

[0013] The beneficial effect of adopting the above-mentioned further technical solution is that the down conductor adopts a cable storage device, which can realize the synchronous lifting and lowering movement of the cable with the lifting structure, avoid the phenomenon of cable entanglement, and fully meet the needs of high lifting structure.

[0014] Furthermore, the cable storage device includes a fixed pulley group and a movable pulley group, both of which are installed in the lifting mechanism, and the middle part of the lower end lead wire is sleeved on the fixed pulley group and the movable pulley group.

[0015] The beneficial effect of adopting the above-mentioned further technical solution is that the down conductor is stored in a straight section between the moving and fixed pulleys. When the lifting mechanism extends, the cable can be released synchronously according to the extended length; when the lifting mechanism is in the retracted state, the cable can be effectively stored. This cable storage device can move the cable without twisting it, and the cable only needs to be wound a few times to be stored in the device, which can fully meet the needs of high-lift structures.

[0016] Furthermore, the two ends of the lower guide wire are respectively fixed to the top and bottom of the lifting mechanism, and a steel wire rope is sleeved between the fixed pulley group and the movable pulley group.

[0017] The beneficial effect of adopting the above-mentioned further technical solution is that the down conductor is stored in a straight section between the moving and fixed pulleys. When the lifting mechanism extends, the cable can be released synchronously according to the extended length; when the lifting mechanism is in the retracted state, the cable can be effectively stored. This cable storage device can move the cable without twisting it, and the cable only needs to be wound a few times to be stored in the device, which can fully meet the needs of high-lift structures.

[0018] Furthermore, the lower guide wire is connected to the steel wire rope, and the length of the lower guide wire is greater than the length of the steel wire rope; the lifting mechanism is provided with a fixed end and a movable end of the guide wire, and the two ends of the lower guide wire are respectively fixed at the position of the fixed end and the position of the movable end.

[0019] The beneficial effect of adopting the above-mentioned further technical solution is that, by adjusting the length of the lower guide wire to be slightly greater than that of the steel wire rope, it is possible to prevent the lower guide wire from bearing excessive tension. At the same time, under the gravity of the movable pulley block, the lower guide wire is basically taut, which can prevent the cable from tangling or other phenomena.

[0020] Furthermore, the lifting mechanism is provided with multiple limiting rods, a reversing fixed pulley group, a movable pulley group guide rail, and multiple guide wheels. The multiple limiting rods are located between the fixed pulley group and the movable pulley group. The lower end guide wire is looped around the outside of the multiple limiting rods, and the lower end guide wire abuts against the multiple guide wheels. The middle part of the lower end guide wire is sleeved on the fixed pulley group and the movable pulley group through the reversing fixed pulley group. The movable pulley group is slidably mounted on the movable pulley group guide rail.

[0021] The beneficial effects of adopting the above-mentioned further technical solution are that, to avoid interference during the winding process of the lower lead wire, and to prevent the lower lead wire from obstructing the sliding of the movable pulley block, multiple limiting rods and guide wheels are set at appropriate positions on the cable storage device. These measures guide and limit the lower lead wire, ensuring that it winds along the planned path and in the planned manner, avoiding crossing or interference with itself or other cables during the winding process. This cable storage device allows for cable movement without cable twisting, and the cable only needs to be wound a few times to be stored in the device, fully meeting the needs of high-lift structures.

[0022] Furthermore, the lightning arrester is located on top of the rotating structure, which is located on top of the lifting mechanism; both the upper and lower down conductors are copper core wires with insulation layers.

[0023] The beneficial effect of adopting the above-mentioned further technical solution is that the lightning arrester is installed on the top of the high-lift rotating structure, enabling early lightning strike interception. The down conductor uses insulated copper core wire, which is insulated from the equipment.

The system installs a lightning arrester 1 at the top of the high-lift rotating structure, forming a complete lightning conduction channel through a lightning discharge ring 3, a down conductor, and a grounding device 8, ensuring that the lightning current can be quickly discharged to the ground. Specifically, the lightning discharge ring 3 is positioned between the rotating and stationary parts of the rotating structure 4, effectively solving the reliability problem of lightning current transmission during rotation; the down conductor uses a specially designed cable storage device 5, enabling the cable to move synchronously up and down with the lifting structure 6, fully adapting to the needs of high-lift structures. Through the above design, this lightning protection system can effectively achieve all-round, blind-spot-free lightning protection for the rotating mechanism 4 and surrounding equipment, significantly improving the system's lightning protection performance and operational reliability.

[0058] This invention provides a lightning protection system for a high-lift rotating structure, comprising a lightning arrester 1, a lightning discharge ring 3, a down conductor, and a grounding device 8. It possesses reliable lightning protection capability and is suitable for high-lift and rotating structures 4. The lightning arrester 1 is installed at the top of the high-lift rotating structure 4 to allow for early lightning strike protection. The lightning discharge ring 3 is positioned between the rotating part (rotating section) and the stationary part (stationary section) at the bottom of the rotating structure 4 for lightning current transmission during rotation. The down conductor connects the lightning arrester 1, the lightning discharge ring 3, and the grounding device 8, and utilizes a specially designed cable management device 5 to prevent cable entanglement.

[0059] The lightning discharge ring 3 is used for the transmission of lightning current between rotating and stationary parts. It is insulated from the outer shell and can withstand instantaneous currents of over 200kA or transient voltages of over 100kV. It can reliably transmit lightning current from high-speed rotating mechanisms to the ground and is suitable for various rotating structures.

[0060] The downlead uses a cable storage device 5 based on a pulley system, with the downlead stored in a straight section between the moving and fixed pulleys. When the lifting mechanism 6 extends, the cable can be released synchronously according to the extended length; when the lifting mechanism 6 is in the retracted state, the cable can be effectively stored. This cable storage device 5 enables cable movement without cable twisting, and the cable only needs to be wound a few times to be stored in the device, which can fully meet the needs of high-lift structures.

[0061] This invention relates to the field of lightning protection, specifically to lightning protection technology for high-lift rotating mechanisms. Compared with existing technologies, this lightning protection system installs a lightning rod 1 at the top of the high-lift rotating structure, and achieves reliable transmission of lightning current to the ground through a lightning discharge ring 3, a down conductor, and a grounding device 8. The lightning discharge ring 3 is located between the rotating part and the stationary part of the rotating structure 4, and the down conductor uses a specialized cable storage device 5, which is fully adaptable to fast-rotating structures and high-lift equipment, effectively solving the current technical problem of reliable lightning protection for high-lift rotating equipment.

[0062] Example 1 like Figures 1 to 3 As shown, this embodiment of the invention provides a lightning protection system for a high-lift rotating structure, comprising a lightning arrester 1, a lightning discharge ring 3, a down conductor, and a grounding device 8, etc., possessing reliable lightning protection capability and suitable for high-lift and rotating structures 4. The lightning arrester 1 is installed at the top of the high-lift rotating structure, enabling pre-lightning protection. The lightning discharge ring 3 is integrated at the bottom of the rotating equipment (rotating structure 4) for the transmission of lightning current between the rotating and stationary parts. The down conductor connects the lightning arrester 1, the lightning discharge ring 3, and the grounding device 8, and employs a specially designed cable management device 5 to accommodate the needs of the high-lift structure. After lightning arrester 1 receives a lightning strike, the lightning current discharge path is: lightning arrester 1 → upper down conductor 2 → lightning discharge ring 3 → lower down conductor 7 → grounding device 8. Throughout the entire 360° rotation of the rotating equipment, this lightning protection system provides comprehensive, blind-spot-free lightning protection for surrounding equipment.

[0063] The lightning discharge ring 3 is used for the transmission of lightning current between rotating and stationary parts. It is insulated from the outer casing and can withstand instantaneous currents exceeding 200kA or transient voltages exceeding 100kV. The conductive ring (lightning discharge ring body 32) of the lightning discharge ring 3 has a cylindrical structure, with the contact surface being the circumference of the conductive ring. The brush filaments (bundled brush filaments 33) employ multi-filament parallel current-carrying transmission to achieve lightning current transmission. Each bundle of brush filaments consists of multiple silver-copper-nickel alloy wires. This design increases the contact area, enabling safe transmission of lightning current.

[0064] The down conductor uses insulated copper core wire, which is insulated from the equipment. The down conductor is divided into an upper down conductor 2 and a lower down conductor 7. The upper down conductor 2 connects the lightning arrester 1 and the rotating part of the lightning discharge ring 3; the lower down conductor 7 is led out from the stationary part of the lightning discharge ring 3 and connected to the grounding device 8. The lower down conductor 7 uses a cable storage device 5 based on a pulley system, stored in a straight section between the movable pulley system 53 and the fixed pulley system 51. One end of the lower down conductor 7 is fixed to the bottom of the lifting mechanism 6, and the other end is fixed to the top of the moving end of the lifting mechanism 6. When the lifting mechanism 6 extends, it drives the steel wire rope to extend, and the movable pulley system 53 moves accordingly, allowing the cable to be released synchronously according to the extended length. When the lifting mechanism 6 is in the retracted state, the lower down conductor 7 can be effectively stored. By adjusting the length of the lower down conductor 7 to be slightly larger than the steel wire rope, excessive tension on the lower down conductor 7 can be prevented. Meanwhile, under the gravity of the movable pulley block 53, the lower lead wire 7 is basically taut, which can prevent the cable from getting tangled.

[0065] To prevent interference during the winding process of the lower guide wire 7, and to avoid it obstructing the sliding of the movable pulley block 53, multiple limiting rods 52 and guide wheels 57 are installed at appropriate positions in the cable storage device 5. These measures guide and limit the lower guide wire 7, ensuring it winds along the planned path and in the planned manner, preventing it from crossing or interfering with itself or other cables during winding. This cable storage device 5 allows cable movement without twisting, and the cable only needs to be wound a few times to be stored in the device, fully meeting the needs of high-lift structures.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; 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 or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
