Description

Technical Field

[0001] This utility model relates to the technical field of bridge protection equipment, and in particular to a double-helix bridge cable protection sleeve with light-emitting function. Background Technology

[0002] In modern bridge engineering, cable-stayed bridges, suspension bridges, and other long-span bridges widely utilize cable structures as their primary load-bearing components. To ensure the durability and safety of cable structures, protective sleeves are typically installed on the outside of the cables to prevent environmental erosion, ultraviolet aging, and mechanical damage. Furthermore, with the development of urban landscape construction, these cable protective sleeves not only serve a protective function but are also gradually integrating additional functions such as lighting and signage to enhance the bridge's nighttime visual appeal and visibility.

[0003] In existing technologies, cable protection sleeves mostly adopt a single cylindrical structure with a smooth outer wall or simple raised structures, lacking an effective design for integration with light guide components. Although some protection sleeves have lighting structures, they suffer from problems such as inconvenient installation, poor structural stability, and uneven light distribution. In addition, the spiral structure of traditional protection sleeves is mostly a single-line design, making it difficult to achieve uniform coverage and aesthetically pleasing layout of the entire cable. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a double-helix bridge cable protection sleeve with a light-emitting function, which can improve the service life of the cable and enhance the aesthetics of the bridge.

[0005] According to a first aspect embodiment of the present invention, a double-helix bridge cable protective sleeve with luminous function includes:

[0006] The shell is a hollow cylinder, which forms an installation cavity for accommodating and fitting onto the outside of the cable. The outer wall of the shell is provided with spirally rising ribs along its extension direction.

[0007] A light-emitting component includes a light guide strip, the bottom of which is provided with a relief portion adapted to the shape of the protruding rib, and the light guide strip is fitted onto the protruding rib through the relief portion;

[0008] The fastening assembly includes a first fastener disposed at the bottom of the light guide strip, wherein the light guide strip is fixedly mounted to the protruding rib by means of the first fastener.

[0009] The double-helix bridge cable protective sleeve with light-emitting function according to the present invention has at least the following beneficial effects: By setting a spirally rising rib along its extension direction on the outer wall of the shell, and setting an abutment part adapted to the shape of the rib at the bottom of the light guide strip, the light guide strip can be installed on the rib by fitting, thereby achieving a stable fit between the light guide strip and the shell. This structure not only improves the convenience of light guide strip installation, but also makes it present a continuous spiral distribution along the extension direction of the cable, enhancing the overall visual guidance effect and nighttime lighting aesthetics of the bridge cable; by setting a first fastener at the bottom of the light guide strip, the light guide strip is firmly fixed to the rib, ensuring the connection reliability of the light guide component in complex outdoor environments, effectively preventing loosening or falling off due to factors such as wind vibration and temperature difference changes, and improving the overall structural stability and service life of the protective sleeve; this double-helix arrangement not only enhances the structural aesthetics of the cable protective sleeve, but also achieves the organic integration of lighting and protection functions, making it suitable for structural protection of bridge cables while improving their nighttime landscape effect.

[0010] According to some embodiments of this utility model, the first fastener is an adhesive, which is disposed between the bottom of the light guide strip and the abutting surface of the rib. The adhesive provides a uniform distribution of bonding stress, avoiding stress concentration problems caused by point fastening and enhancing the connection stability between the light guide strip and the housing. Furthermore, the adhesive also has good sealing properties, effectively preventing external moisture and dust from entering the joint surface between the light guide strip and the rib, improving the structure's weather resistance and long-term reliability.

[0011] According to some embodiments of this utility model, the first fastener is fixed by double-sided adhesive tape. While achieving rapid fixing, the double-sided adhesive tape also possesses good adhesive strength and flexibility, capable of adapting to minor deformations caused by temperature differences or vibrations between the housing and the light guide strip, thereby improving the stability and durability of the connection structure.

[0012] According to some embodiments of this utility model, the fastening assembly further includes a second fastener, which is a clamp. The clamp presses and fixes the light guide strip to the interlocking structure of the rib through radial constraint force. The press-fit between the clamp and the rib can achieve a stable fixation without damaging the structure of the light guide strip itself, maintaining the integrity of the sheath's appearance and the continuity of the lighting effect, further improving the overall performance of the bridge cable protection sleeve in terms of structural safety, construction convenience, and landscaping aesthetics.

[0013] According to some embodiments of this utility model, the clamps are arranged in an array with spacing along the extension direction of the shell, and the center-to-center distance between adjacent clamps is configured to be 2 meters. This spacing, combined with the interlocking structure of the light guide strip and the rib, forms a dual fixing method of "adhesion and mechanical compression," significantly improving the connection reliability of the light guide assembly during long-term use. Especially under complex conditions such as wind vibration and temperature variations, it effectively prevents components from loosening or falling off, thereby improving the overall safety and durability of the bridge cable protection sleeve.

[0014] According to some embodiments of this utility model, the light-emitting component further includes a light-emitting strip, which is disposed through the light guide strip along its extension direction. Positioning the light-emitting strip behind the light guide strip enables uniform light source introduction, improving the light transmission efficiency and illumination uniformity of the light guide strip, thereby enhancing the nighttime visual guidance effect and landscaping aesthetics of the bridge cable. Furthermore, this arrangement also provides a certain degree of protection, reducing the impact of the external environment on the light-emitting strip, extending its service life, and improving the overall system's reliability and maintenance convenience.

[0015] According to some embodiments of this utility model, the light guide strip is further provided with a first wire-passing hole and a second wire-passing hole, which are respectively located on opposite sides of the light-emitting strip. This can significantly alleviate the problem of voltage drop at the end caused by excessive length of the light strip, ensure the uniformity and stability of the overall brightness of the light strip, and improve the nighttime lighting and landscape effect.

[0016] According to some embodiments of this utility model, the cross-section of the protruding rib is a first semi-annular structure, and the cross-section of the light guide strip is a second semi-annular structure complementary to the first semi-annular structure. The first semi-annular structure and the second semi-annular structure are interlocked to form a complete semi-annular cross-section. This mating method not only improves the connection accuracy and stability between the light guide strip and the housing, but also effectively enhances the contact area and mechanical support performance between the two, thereby improving the overall structure's anti-slip capability and load-bearing capacity. This complementary interlocking structure ensures the ease of installation of the light guide strip while also helping to improve its connection reliability under complex working conditions such as wind vibration, temperature changes, or mechanical impact, preventing problems such as displacement or detachment of the light guide strip due to uneven force.

[0017] According to some embodiments of this utility model, the outer wall of the housing is provided with two convex ribs. The two convex ribs are coiled alternately around the extension direction of the housing with a constant pitch. Two sets of light-emitting components are correspondingly provided and respectively fitted onto the fitting structure of the two convex ribs. The double-rib structure enhances the radial stiffness of the housing and also provides a more stable and balanced mounting foundation for the light-emitting components.

[0018] According to some embodiments of this utility model, the light guide strip is made of a light-transmitting material. By using a light-transmitting material for the light guide strip, the light transmission efficiency and distribution uniformity can be effectively improved, so that the light emitted by the light strip achieves a soft, continuous, and uniform lighting effect after passing through the light guide strip, avoiding the problem of local bright spots or dark areas.

[0029] Reference Figures 1 to 3 A protective sleeve for double-helix bridge cables with luminous function, including:

[0030] The housing 100 is a hollow cylinder. The housing 100 forms an installation cavity for accommodating and fitting onto the outside of the cable. The outer wall of the housing 100 is provided with a spirally rising rib 120 along its extension direction.

[0031] The light-emitting component includes a light guide strip 110. The bottom of the light guide strip 110 is provided with a relief portion 160 that is adapted to the shape of the protruding rib 120. The light guide strip 110 is fitted onto the protruding rib 120 through the relief portion 160.

[0032] The fastening assembly includes a first fastener, which is disposed at the bottom of the light guide strip 110, and the light guide strip 110 is fixedly installed on the protruding rib 120 by the first fastener.

[0033] By providing a spirally rising rib 120 on the outer wall of the housing 100 and providing a relief portion 160 at the bottom of the light guide strip 110 that matches the shape of the rib 120, the light guide strip 110 can be installed on the rib 120 by fitting, thereby achieving a stable fit between the light guide strip 110 and the housing 100. This structure not only improves the ease of installation of the light guide strip 110, but also makes it present a continuous spiral distribution along the extension direction of the cable, enhancing the overall visual guidance effect and nighttime lighting aesthetics of the bridge cable. By setting the first fastener at the bottom of the light guide strip 110, the light guide strip 110 is firmly fixed to the protruding rib 120, ensuring the connection reliability of the light guide component in complex outdoor environments, effectively preventing loosening or detachment caused by factors such as wind vibration and temperature differences, and improving the overall structural stability and service life of the protective sleeve. This double spiral arrangement not only enhances the structural aesthetics of the cable protective sleeve, but also achieves an organic integration of lighting and protection functions, making it suitable for structural protection of bridge cables while enhancing their nighttime landscape effect.

[0034] Cable stays are prone to vortex-induced vibration under wind loads, and long-term vibration can lead to fatigue damage in the cable body, affecting structural durability and safety. This invention employs a double-helix structure, which can create asymmetric airflow disturbance around the cable, effectively disrupting the regular separation of airflow on the cable surface, suppressing periodic vortex shedding, and thus significantly reducing the probability of wind-induced vibration and improving the cable system's resistance to wind vibration. The spiral protrusion structure on the outer wall of the shell 100 effectively enhances the radial stiffness of the sheath tube, improving its resistance to compression, bending, and torsion in complex environments, thereby enhancing the overall mechanical properties of the structure. Under dynamic loads (such as wind loads, rain vibration, traffic vibration, etc.), the spiral protrusion structure can achieve uniform stress distribution, avoiding stress concentration, thus reducing the initiation of local fatigue cracks and extending the service life of the sheath and cable structure. The spiral protrusion structure can form an effective drainage channel, guiding rainwater to quickly drain away from the cable surface along the spiral path, reducing water droplet retention and accumulation, and preventing the deposition of corrosive media on the surface. Furthermore, the spiral structure helps reduce the adhesion time of water films on the sheath surface, mitigating the impact of humid environments on material properties, slowing down the aging process under the combined effects of UV radiation and moisture, and further enhancing the sheath's weather resistance and durability. During installation or maintenance, the spiral protrusions increase the friction coefficient of the sheath surface, improving the grip of workers and equipment, effectively preventing slippage, and enhancing construction safety and ease of operation. In cold regions, falling icicles or ice accumulation can cause impact damage to the cable sheath. The spiral protrusions have a certain ability to buffer and disperse impact forces, effectively reducing the risk of damage from concentrated ice loads and improving the sheath's resistance to ice impact in low-temperature environments.

[0035] The first fastener is an adhesive, which is placed between the bottom of the light guide strip 110 and the mating surface of the protruding rib 120. The adhesive provides a uniform distribution of bonding stress, avoiding stress concentration problems caused by point fastening, and enhancing the connection stability between the light guide strip 110 and the housing 100. In addition, the adhesive also has good sealing performance, effectively preventing external moisture and dust from entering the mating surface between the light guide strip 110 and the protruding rib 120, improving the weather resistance and long-term reliability of the structure.

[0036] The first fastener is made of adhesive and is positioned between the bottom of the light guide strip 110 and the abutment surface of the rib 120 of the housing 100. During installation, after the light guide strip 110 is aligned and fitted along the spiral path of the rib 120, adhesive is applied between the bottom of the light guide strip 110 and the contact surface of the rib 120 to form a continuous and uniform adhesive layer, thereby achieving a firm connection between the light guide strip 110 and the housing 100.

[0037] After curing, the adhesive forms a connection interface with a certain bonding strength and elasticity, which can transfer and distribute the force between the light guide strip 110 and the rib 120, avoiding the local stress concentration problem caused by traditional point fastening (such as screws or clips). This uniform stress distribution effectively improves the connection stability of the light guide strip 110 in complex environments and reduces the risk of cracking or falling off the light guide strip 110 due to uneven stress.

[0038] The first fastener is fixed by double-sided tape. While achieving quick fixation, the double-sided tape also has good adhesive strength and flexibility, which can adapt to the slight deformation between the housing 100 and the light guide strip 110 caused by temperature difference or vibration, thereby improving the stability and durability of the connection structure.

[0039] During installation, after aligning and fitting the bottom of the light guide strip 110 with the protruding rib 120 structure on the housing 100, double-sided tape is pre-attached to the contact surface between the bottom of the light guide strip 110 and the protruding rib 120. By pressing, the upper and lower adhesive surfaces of the double-sided tape are firmly bonded to the light guide strip 110 and the protruding rib 120 respectively, thereby achieving rapid fixation of the light guide strip 110.

[0040] The fastening assembly also includes a second fastener, which is a clamp. The clamp presses and fixes the light guide strip 110 to the interlocking structure of the rib 120 through radial constraint force. The press-fit between the clamp and the rib 120 can achieve a stable fixation without damaging the structure of the light guide strip 110, maintaining the integrity of the sheath's appearance and the continuity of the lighting effect, further improving the overall performance of the bridge cable protection sheath in terms of structural safety, construction convenience, and landscaping.

[0041] During installation, after the light guide strip 110 is fitted onto the protruding rib 120 of the housing 100 via the bottom clearance part 160 and initially bonded and fixed by the first fastener, the clamps are then fitted onto the outside of the light guide strip 110 and spaced apart along the extension direction of the housing 100. The clamps, through their own elasticity or adjustable structure, generate a uniform radial constraint force during the tightening process, pressing the light guide strip 110 against the mating surface of the protruding rib 120, thereby achieving a mechanical secondary fixation of the light guide strip 110.

[0042] The clamps are arranged in an array along the extension direction of the housing 100, with a center-to-center spacing of 2 meters between adjacent clamps. This spacing, combined with the interlocking structure of the light guide strip 110 and the protruding rib 120, forms a dual fixing method of "adhesion and mechanical compression," which significantly improves the connection reliability of the light guide assembly during long-term use. Especially under complex working conditions such as wind vibration and temperature changes, it can effectively prevent components from loosening or falling off, thereby improving the overall safety and durability of the bridge cable protection sleeve.

[0043] During actual installation, the light guide strip 110 is first initially positioned with the protruding rib 120 of the housing 100 through a fitting structure, and then initially fixed with the help of a first fastener (such as adhesive or double-sided tape). Subsequently, clamps are installed every 2 meters along the axial direction of the housing 100. Through the radial pressure generated by their own structure, the light guide strip 110 is further pressed against the fitting surface of the protruding rib 120, thereby achieving mechanical reinforcement and fixation of the light guide assembly.

[0044] The light-emitting component also includes a light strip 130, which is housed within a light guide strip 110. The placement of the light strip 130 within the light guide strip 110 enables uniform light source introduction, improving the light transmission efficiency and illumination uniformity of the light guide strip 110, thereby enhancing the nighttime visual guidance effect and landscaping aesthetics of the bridge cables. Furthermore, this arrangement provides a degree of protection, reducing the impact of the external environment on the light strip 130, extending its service life, and improving the overall system's reliability and ease of maintenance.

[0045] During installation, the LED strip 130 is directly embedded inside the light guide strip 110, eliminating the need for additional mounting slots. After the LED strip 130 is powered on, the light emitted is conducted, scattered, and distributed through the optical structure inside the light guide strip 110, thereby achieving the overall lighting effect.

[0046] The light guide strip 110 also has a first wire guide hole 140 and a second wire guide hole 150, which are respectively located on opposite sides of the light strip 130. This can significantly alleviate the problem of voltage drop at the end caused by excessive length of the light strip, ensure the uniformity and stability of the overall brightness of the light strip, and improve the nighttime lighting and landscape effect.

[0047] A first wire-passing hole 140 and a second wire-passing hole 150 are respectively provided on opposite sides of the light-emitting strip 130. This structural design provides a reasonable wiring channel for the power supply line of the light-emitting strip 130, allowing the power line to pass through and exit from different directions of the light guide strip 110, meeting the wiring requirements of different installation scenarios. In practical applications, the power line can pass through the first wire-passing hole 140, connect to the light-emitting strip 130, and then exit from the second wire-passing hole 150 on the other side, realizing continuous wiring or loop connection. This wiring method is particularly suitable for scenarios where the light guide strip 110 is continuously arranged over long distances in bridge cable protection sleeves.

[0048] By providing wire-passing holes on both sides of the light strip 130, multi-point power supply or bidirectional wiring can be achieved, effectively shortening the power supply path of a single section of the light strip, reducing the problem of insufficient voltage at the end due to excessive strip length, and ensuring the uniformity and stability of light brightness. The power cord can flexibly choose its entry and exit direction to adapt to different construction environments and wiring routes, improving installation efficiency, especially suitable for bridge lighting projects under high-altitude or complex wiring conditions. A reasonable wiring structure helps reduce the number of wire joints, lowering the failure rate, while facilitating later maintenance and replacement, improving the maintainability and operational stability of the overall lighting system. The wire-passing holes are integrated inside the light guide strip 110, avoiding cluttered external wiring, maintaining the neat appearance of the bridge cables, and further enhancing the functionality and landscape harmony of the lighting system.

[0049] The cross-section of the rib 120 is a first semi-annular structure, and the cross-section of the light guide strip 110 is a second semi-annular structure that complements the first semi-annular structure. The first and second semi-annular structures interlock to form a complete semi-annular cross-section. This mating method not only improves the connection accuracy and stability between the light guide strip 110 and the housing 100, but also effectively enhances the contact area and mechanical support performance between the two, thereby improving the overall structure's anti-slip capability and load-bearing capacity. This complementary interlocking structure ensures the ease of installation of the light guide strip 110, while also helping to improve its connection reliability under complex working conditions such as wind vibration, temperature changes, or mechanical impact, preventing the light guide strip 110 from shifting or falling off due to uneven force.

[0050] The outer wall of the housing 100 is provided with two protruding ribs 120. The two protruding ribs 120 are coiled alternately with a constant pitch along the extension direction of the housing 100. Two sets of light-emitting components are provided accordingly, and are respectively fitted and installed on the fitting structure of the two protruding ribs 120. The double protruding rib structure 120 not only enhances the radial stiffness of the housing 100, but also provides a more stable and balanced mounting foundation for the light-emitting components.

[0051] Two convex ribs 120 provide a dual-line mounting path for the light guide strip 110. The light guide strip 110 is sequentially embedded and installed along the spiral direction of the convex ribs 120 through the adapter structure (such as a semi-circular interlocking surface) at its bottom. Two sets of light-emitting components are arranged along the two convex ribs 120 respectively, forming a double-helix light-emitting structure surrounding the housing 100.

[0052] The light guide strip 110 is made of a light-transmitting material. By using a light-transmitting material for the light guide strip 110, the light transmission efficiency and distribution uniformity can be effectively improved. This allows the light emitted from the LED strip 130 to achieve a soft, continuous, and uniform lighting effect after passing through the light guide strip 110, avoiding problems such as localized bright spots or dark areas. The light-transmitting material itself has good insulation properties, effectively isolating the LED strip 130 from the external environment and improving the safety of the entire lighting system, making it especially suitable for complex climatic conditions such as humidity and rain.

[0053] The housing 100 is a hollow cylindrical structure used to fit over the bridge cables, forming a space to effectively protect them. Two protruding ribs 120 are provided on the outer wall of the housing 100 along its extension direction. These two ribs 120 are interlaced with a constant pitch, forming a double helix structure. The cross-section of each rib 120 has a first semi-annular structure, used to form a stable interlocking connection with the light guide strip 110.

[0054] The light-emitting component includes a light guide strip 110 and a light-emitting strip 130. The light guide strip 110 is made of a light-transmitting material (such as PMMA or PC), and its cross-section has a second semi-annular structure complementary to the rib 120, allowing it to fit tightly against the mating surface of the rib 120. A clearance portion 160 is provided at the bottom of the light guide strip 110, allowing it to be smoothly embedded and installed along the spiral path of the rib 120. A through-type light-emitting strip 130 is provided inside the light guide strip 110 along its extension direction. Furthermore, the light guide strip 110 also has a first wire-passing hole 140 and a second wire-passing hole 150, respectively located on opposite sides of the light-emitting strip 130, facilitating the entry and exit of power cables and multi-point power supply arrangements.

[0055] The fastening assembly includes a first fastener and a second fastener. The first fastener, made of double-sided tape or adhesive, is positioned between the bottom of the light guide strip 110 and the abutment surface of the protruding rib 120 to achieve initial bonding and fixation between the light guide strip 110 and the protruding rib 120. The second fastener is a clamp, arranged in an array with a center-to-center spacing of 2 meters along the extension direction of the housing 100. The clamp further presses the light guide strip 110 onto the interlocking structure of the protruding rib 120 through radial constraint force, achieving mechanical reinforcement and fixation. This forms a dual fixing method of "adhesion plus compression," significantly improving the connection stability and wind resistance of the light guide strip 110.

[0056] In actual operation, the housing 100 is first fitted onto the outside of the bridge cable, and then the light guide strip 110 is aligned and fitted along the spiral path of the rib 120. The light guide strip 110 achieves rapid positioning by forming a surface contact with the first semi-annular structure of the rib 120 through the second semi-annular structure at its bottom. Next, double-sided tape or adhesive is applied between the light guide strip 110 and the rib 120 to complete the first fastening step. Finally, clamps are installed every 2 meters on the outside of the light guide strip 110 to further tighten and fix it through radial pressure.

[0057] The LED strip 130 emits light when powered on after being embedded in the light guide strip 110. The light is conducted, scattered, and evenly distributed through the light-transmitting material of the light guide strip 110, and finally output from the outer surface of the light guide strip 110, creating a continuous and soft lighting effect. The power cord enters through the first wire hole 140, connects to the LED strip, and exits through the second wire hole 150, achieving reasonable wiring layout and load balancing, preventing insufficient voltage at the end due to excessive LED strip length.

[0058] In this embodiment, the double helix structure not only enhances the structural rigidity and wind resistance of the housing 100, but also achieves symmetrical arrangement of the light-emitting components around the cable, improving the lighting coverage and visual guidance effect. Simultaneously, the combination of the light-transmitting guide strip 110 and the interlocking installation structure improves light transmission efficiency and overall aesthetics, making it suitable for integrated applications of functional protection and landscape lighting for bridge cables.

[0059] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
