Description

Technical Field

[0001] This utility model relates to the field of optical cable laying technology, specifically to a temperature-sensing optical cable laying mechanism and an integrated cable support for installation. Background Technology

[0002] On the high-voltage side of existing underground tunnels, such as the power lighting and ring network cable side, fire detection equipment needs to be installed at locations of equipment and cables prone to fire to ensure construction and operation safety. Currently, laying heat-sensing optical cables is commonly used to meet fire detection requirements.

[0003] There are two main methods for fixing existing temperature-sensing optical cables. One method involves installing support frames at predetermined intervals within the tunnel, securing steel wire ropes to the support frames, and then laying the optical cable along the steel wire ropes and binding it to the ropes for fixation. The other method involves shortening the spacing between support frames and directly fixing the optical cable through each support frame sequentially. However, both existing methods require the fabrication of numerous support frame structures, each of which needs to be fabricated and fixed individually. This results in high fabrication and construction costs, long construction periods, significant time spent working at heights, numerous potential installation hazards, and potential interference with existing power cable supports. These methods fail to meet operational and construction requirements and make it difficult to ensure that the temperature-sensing optical cable maintains the predetermined distance from locations that could affect the sensing results, such as lighting fixtures and pantographs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where temperature-sensing optical cables are laid using separately prepared and fixed support frames, which cannot meet construction requirements, and to provide a temperature-sensing optical cable laying mechanism and an integrated installation cable bracket.

[0005] In a first aspect, the present invention provides a temperature-sensing optical cable laying mechanism, including a hanging component, wherein the hanging component is a block-shaped structural component or a sheet-shaped structural component, and the hanging component is provided with a through limiting groove, wherein the limiting groove includes a guide section and a limiting section, wherein the end of the limiting section away from the guide section is set as a blind end, and the end of the guide section away from the limiting section is set as an open end, wherein the open end is located on the lateral sidewall of the hanging component.

[0006] This utility model discloses a temperature-sensing optical cable laying mechanism. By using block-shaped or sheet-shaped structural components as hanging parts, the structure is simple and can be easily pre-installed and fixed to other structures on site. The temperature-sensing optical cable can be laid along the through direction of the limiting groove, which is convenient to operate. The installation distance between the hanging parts and the position to be sensed can meet the sensing distance requirements of the temperature-sensing optical cable, reducing the difficulty and cost of laying the temperature-sensing optical cable and shortening the construction period.

[0007] Preferably, the guide section and the limiting section are connected in a straight line, and there is a height difference between the blind end and the open end in the height direction of the hanging component. The temperature-sensing optical cable can be stably restricted within the limiting groove by the limiting section, and is not easily detached from the hanging component.

[0008] Preferably, the top end of the limiting segment is connected to the guide segment at an angle. This further improves the limiting effect on the temperature-sensing optical cable.

[0009] Preferably, the blind end has an arc-shaped bottom surface, the open end has an arc-shaped guide surface, and the intersection of the guide section and the limiting section has an arc-shaped transition surface. This makes the temperature-sensing optical cable less prone to scratch damage during installation and use.

[0010] Preferably, the internal space of the limiting segment gradually increases along the direction from the guide segment to the blind end. This further improves the limiting effect on the temperature-sensing optical cable.

[0011] Preferably, the hanging component is provided with mounting holes, and the mounting holes are equipped with limiting components. This allows the hanging component to be detachably connected to other structures on site according to actual conditions.

[0012] Preferably, the number of the limiting grooves is at least one, to satisfy the laying limitation of at least one temperature-sensing optical cable.

[0013] In a second aspect, this utility model provides an integrated installation cable bracket, including a vertical support, on which a support arm is provided, and on which at least one of the temperature-sensing optical cable laying mechanisms described above is provided, wherein the distance between the support arm and the blind end can meet the detection distance requirements of the temperature-sensing optical cable.

[0014] This utility model discloses an integrated installation cable bracket, which combines a temperature-sensing optical cable laying mechanism with a bracket for laying other cables to form an integrated installation cable bracket. This allows the temperature-sensing optical cable to maintain a stable sensing distance with other cables on the bracket, avoiding the need to separately prepare and install the temperature-sensing optical cable support frame, reducing the installation cost of the temperature-sensing optical cable, and shortening the construction cycle.

[0015] Preferably, at least two support arms are provided at intervals along the height direction on the vertical support, the included angle between the support arm and the vertical support is M, M≤90°, the support arm is provided with cable limiting holes, and the hanging component is welded to or detachably connected to the uppermost support arm.

[0016] Preferably, there are at least two vertical supports, and at least one horizontal support is provided between adjacent vertical supports. The horizontal supports and / or the vertical supports are provided with fixing holes, and the horizontal supports are provided with stiffening ribs. Each of the uppermost support arms is provided with a hanging component. This increases the lateral width of the cable support, expands the support range, improves the stability of cable laying, and reduces the total number of supports in the project.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 2. This utility model provides a temperature-sensing optical cable laying mechanism, which allows the temperature-sensing optical cable to be laid along the through direction of the limiting groove.

[0020] 3. This utility model provides an integrated installation cable bracket. By combining the temperature-sensing optical cable laying mechanism with other cable laying brackets, an integrated installation cable bracket is formed, which enables the temperature-sensing optical cable to maintain a stable sensing distance with other cables on the bracket.

[0036] Example 1

[0037] like Figures 1-4 As shown, a temperature-sensing optical cable laying mechanism includes a hanging component 1, on which a through-type limiting groove 11 is provided.

[0038] In one or more embodiments, the hanging component 1 can be a block-shaped structural component or a sheet-shaped structural component, used to connect with other structures at the temperature-sensing optical cable laying site. The limiting groove 11 provided on it restricts the movement of the temperature-sensing optical cable in a direction perpendicular to its own longitudinal direction. The limiting groove 11 can be a channel structure that runs through the thickness direction of the hanging component 1. By combining multiple hanging components 1, the temperature-sensing optical cable is laid along the through direction of the limiting groove 11, and the multiple hanging components 1 limit and stabilize it.

[0039] In an optional embodiment, the hanging component 1 can be a rectangular steel sheet structure with a limiting groove 11 cut into it. The structure is simple and easy to manufacture. The hanging component 1 with the steel sheet structure can be welded to the relevant cable brackets at the site during factory prefabrication, reducing the on-site installation process of the hanging component 1, which helps to shorten the construction cycle and can quickly provide an installation position that can maintain a suitable sensing distance for the laying of temperature-sensing optical cables.

[0040] In one or more embodiments, the guide section 2 and the limiting section 3 form a limiting groove 11. The limiting groove 11 is a channel structure formed on the cross-section of the hanging member 1 perpendicular to the through direction, with one end being a blind end 31 and the other end being a channel that penetrates the transverse side wall of the hanging member 1. This allows the temperature-sensing optical cable to enter the limiting section 3 after passing through the conductor section and be restricted by the limiting section 3. When subjected to the transverse force of the hanging member 1, it is not easy to detach from the hanging member 1.

[0041] In optional implementations, such as Figure 1As shown, the guide section 2 and the limiting section 3 are connected in a straight line. There is a height difference between the blind end 31 and the open end 21 in the height direction of the hanging component 1, so that the limiting groove 11 is tilted on the hanging component 1. The temperature sensing optical cable moves from the relatively high open end 21 into the limiting groove 11 until it enters the limiting section 3. It can be stably limited by the limiting section 3 in the limiting groove 11, and it is not easy to detach from the hanging component 1 when subjected to lateral force.

[0042] In an optional embodiment, the top end of the limiting segment 3 is connected to the guide segment 2 at an angle, and the angle between the guide segment 2 and the limiting segment 3 can be N, which further improves the limiting effect on the temperature-sensing optical cable.

[0043] Specifically, such as Figure 2 As shown, the limiting section 3 can be set along the height direction of the hanging component 1, and the included angle N between the guide section 2 and the limiting section 3 can satisfy: 90°≤N<180°, so that the limiting effect is more stable after the temperature sensing optical cable enters the limiting groove 11.

[0044] In optional implementations, such as Figure 3 As shown, the thickness of the steel sheet hanger 1 can be 5mm, the width 30mm, and the height 110mm. The top of the open end 21 is 35-40mm away from the top of the hanger 1, and the bottom of the blind end 31 is 10mm away from the bottom of the hanger 1.

[0045] Specifically, such as Figure 3 As shown, the limiting section 3 can be set along the height direction of the hanging component 1, and the included angle N between the guide section 2 and the limiting section 3 can also satisfy: N < 90°, so that there is a reverse included angle between the limiting section 3 and the guide section 2, and the temperature sensing optical cable can enter the limiting section 3 after a certain turning during the movement, so as to achieve a better stable limiting effect.

[0046] It is understandable that the shape and size of the limiting groove 11 on the hanging part 1 can be adjusted according to the actual situation. This allows the temperature sensing optical cable to enter the limiting section 3 after changing its direction of movement multiple times. Alternatively, the overall size of the limiting groove 1 can be adjusted to achieve a better stable limiting effect to the greatest extent, preventing the temperature sensing optical cable from detaching from the hanging part 1 due to external force during use. This ensures that the temperature sensing optical cable can continuously sense the position to be sensed and guarantees the normal operation of the relevant monitoring system.

[0047] In one or more embodiments, the blind end 31 is provided with an arc-shaped bottom surface 32, the open end 21 is provided with an arc-shaped guide surface 22, and an arc-shaped transition surface 23 is provided at the intersection of the guide section 2 and the limiting section 3. This makes the temperature-sensing optical cable less prone to scratch damage during installation and use.

[0048] In an optional embodiment, the arc-shaped bottom surface 32, the arc-shaped guide surface 22, and the arc-shaped transition surface 23 are all arc-shaped surfaces set in the moving direction of the temperature-sensing optical cable during the cutting and preparation process of the limiting groove 11, so as to avoid the temperature-sensing optical cable being scratched during the movement, ensure the smooth and safe installation of the temperature-sensing optical cable, and ensure the use effect after installation.

[0049] In one or more embodiments, the limiting segment 3 can gradually increase in internal space along the direction from the guide segment 2 to the blind end 31, further improving the limiting effect on the temperature-sensing optical cable.

[0050] In optional implementations, such as Figures 1-4 As shown, the limiting segment 3 can be set along the height direction of the hanging member 1, and its width gradually increases along the direction from the top to the bottom of the hanging member 1.

[0051] In one or more embodiments, the hanging component 1 may be provided with mounting holes 4, and the mounting holes 4 may be equipped with limiting components. This allows the hanging component 1 to be detachably connected to other structures on site according to actual conditions.

[0052] In an optional embodiment, the mounting hole 4 can be a round hole provided on the hanging component 1, and the limiting component can be a conventional connecting component such as a bolt or rivet that can pass through the mounting hole 4, so that the hanging component 1 can be welded and fixed according to the actual situation, or it can be detachably installed and fixed according to the actual situation.

[0053] In one or more embodiments, the number of limiting grooves 11 is at least one, to satisfy the laying limitation of at least one temperature-sensing optical cable.

[0054] In an optional implementation, the number of limiting grooves 11 is related to the required number of temperature-sensing optical cables at the construction site and the distance to the location to be sensed, so that the continuous sensing requirements for different locations to be sensed can be met by increasing the number of temperature-sensing optical cables laid.

[0055] This embodiment of a temperature-sensing optical cable laying mechanism uses a hanging component 1 with block or sheet-like structural components. The structure is simple and can be easily pre-installed and fixed to other structures on site. The temperature-sensing optical cable can be directly placed into the limiting groove 11 from the open end 21 and laid along the through direction of the limiting groove 11. Compared with the existing solution, which requires the perforation and laying of temperature-sensing optical fibers, this is more convenient. The installation distance between the hanging component 1 and the position to be sensed can meet the sensing distance requirements of the temperature-sensing optical cable, reducing the laying difficulty and cost of the temperature-sensing optical cable, shortening the construction period, and improving the performance of the temperature-sensing optical cable.

[0056] Example 2

[0057] like Figures 5-7As shown, an integrated cable support includes a vertical support 5, a bracket 6, and at least one temperature-sensing optical cable laying mechanism as described above. The distance between the bracket 6 and the blind end 31 can meet the detection distance requirements of the temperature-sensing optical cable.

[0058] In one or more embodiments, both the vertical support 5 and the support arm 6 can be angle steel structural components. The vertical support 5 can be set vertically, the support arm 6 is connected to the vertical support 5, and the hanging component 1 can be connected to the bottom of the support arm 6. By laying the relevant cables and equipment to be sensed along the support arm 6 and laying the temperature sensing optical cable along the limiting groove 11 on the hanging component 1, the temperature sensing optical cable can maintain a limited distance from the position to be sensed, so that the temperature sensing optical cable and the cable and equipment to be sensed can be integrated and installed at a single support point through a single bracket.

[0059] In an optional embodiment, at least two support arms 6 can be provided at intervals along the height direction on the vertical support 5. The included angle between the support arm 6 and the vertical support 5 is M, where M≤90°. The support arm 6 is provided with a cable limiting hole 61. The hanging component 1 can be welded to or detachably connected to the uppermost support arm 6. The relative angle between the support arm 6 and the vertical support 5 can be adjusted according to the actual situation, and the relative positional relationship between the hanging component 1 and the vertical support 5 and the support arm 6 can be adjusted to meet the laying requirements of the temperature-sensing optical cable under different working conditions.

[0060] In one or more embodiments, there may be two vertical supports 5, and at least one horizontal support 7 is provided between adjacent vertical supports 5. The horizontal support 7 and / or the vertical support 5 are provided with fixing holes 8. The horizontal support 7 is provided with stiffening ribs 9. Each support arm 6 of the uppermost layer is provided with a hanging part 1. In use, the bracket is fixed as a whole by the connector passing through the fixing hole 8, and the horizontal support 7 increases the lateral width of the cable bracket, expands the support range of a single bracket, improves the stability of cable laying, and thus reduces the total number of brackets in the project.

[0061] This embodiment of an integrated installation cable bracket combines a temperature-sensing optical cable laying mechanism with a bracket for laying other cables to form an integrated installation cable bracket. This allows the temperature-sensing optical cable to maintain a stable sensing distance with other cables on the bracket, avoiding the need for separate fabrication and installation of the temperature-sensing optical cable support frame. This reduces the installation cost of the temperature-sensing optical cable. Furthermore, the hanging component 1 can be welded to other cable laying brackets during the factory prefabrication stage, which not only shortens the construction cycle but also ensures stable installation of the hanging component 1. This ensures that the temperature-sensing optical cable is under stable stress during use, is not prone to displacement, and facilitates later maintenance.

[0062] To further verify the structural reliability of the integrated installation cable bracket in this embodiment, taking an integrated installation cable bracket with multi-layered support arms 6 using a steel plate hanger 1 with a thickness of 5mm, a width of 30mm, a height of 110mm, a top distance of 35-40mm from the top of the open end 21 to the top of the hanger 1, and a bottom distance of 10mm from the bottom of the blind end 31 to the bottom of the hanger 1 as an example, the hanger 1 is placed below the uppermost support arm 6, and a stress analysis is performed on the key parts including the hanger 1, specifically including:

[0063] Load analysis of hanging component 1: During use, hanging component 1 mainly bears the static load of the temperature-sensing optical cable, such as the optical cable material and sheath, as well as the dynamic tension during construction / maintenance, such as manual pulling, equipment vibration, and wind load. Therefore, the maximum load that hanging component 1 needs to bear during use can be determined.

[0064] Limiting groove 11 design: The inner bottom surface of the limiting groove 11 on the hanging part 1 is set as an arc-shaped bottom surface 32, and an arc-shaped guide surface 22 is set. This can effectively disperse stress and avoid stress concentration during use. Through finite element simulation, it is found that the maximum bending stress of the hanging part 1 when subjected to lateral tensile force is 85MPa, which is lower than the allowable stress of Q235 steel of 160MPa, thus meeting the strength requirements.

[0065] Load analysis of bracket 6: The design load-bearing capacity of a single bracket 6 depends on the cable material to be supported, including optical cables and auxiliary equipment. Taking bracket 6 made of 50×50×5mm angle steel as an example, its moment of inertia is 22.8cm. 4 Based on a safety factor of 1.5, its maximum bending stress can be calculated as 105 MPa using the formula σ=My / I, which meets the strength requirements of Q235 steel.

[0066] Load analysis of vertical brace 5: Vertical brace 5 can be formed by combining two angle steels, which can be composed of two 50×50×5mm angle steels. Based on Euler's formula, its buckling critical load can be calculated to be 12kN, which is much greater than the actual load (2kN / bracket × 3 layers = 6kN), meeting the usage requirements and avoiding the risk of instability.

[0067] Analysis of cross brace 7 and stiffening rib 9: Cross brace 7 and stiffening rib 9 can control the overall lateral deformation within 3mm, thereby ensuring the stability of the gap between the temperature sensing optical cable and the support arm 6, which can meet the requirement of detection distance within ±5mm error range.

[0068] Dynamic operating condition adaptability analysis: The integrated installation cable bracket is made entirely of steel, and the coefficient of linear expansion of the material is 12×10⁻ 6 / ℃, at a temperature difference of 30℃, the vertical brace 5 has an expansion and contraction of 0.72mm. The flexible connection design of the horizontal brace 7 absorbs the deformation and can avoid the generation of additional stress inside the structure.

[0069] Vibration analysis: Based on model analysis, the first natural frequency of the integrated installation cable bracket is found to be 5-10Hz away from the common environmental vibration frequency, which can effectively avoid the risk of resonance.

[0070] Overall load distribution optimization: Due to the adoption of a multi-layer bracket 6 structure and the installation of the hanging component 1 below the uppermost bracket 6, the total load is evenly distributed to the vertical support 5. It can be known that the maximum stress point is located at the bottom of the vertical support 5, which is calculated to be 90MPa by the model, and the safety factor reaches 1.8.

[0071] Preferably, when the hanging component 1 is fixed by using bolts to cooperate with the mounting holes 4, for example, when M10 bolts are used for fixing, the shear stress is 45MPa, which is much lower than the allowable shear stress of 120MPa of the bolt material. Therefore, using this bolt connection can ensure the reliable connection of the hanging component 1 under stress.

[0072] The integrated cable support in this embodiment, as shown by stress analysis, meets the engineering requirements in terms of static, dynamic, and stability aspects. Under dynamic loads during construction / maintenance, the hanger 1 remains stable and avoids structural deformation, enabling stable installation of the temperature-sensing optical cable. Furthermore, the detailed design of the upper limit groove 11 of the hanger 1, including its arc-shaped bottom surface 32, arc-shaped guide surface 22, and stiffening ribs 9, significantly reduces the risk of stress concentration and deformation, ensuring stable spacing between the temperature-sensing optical cable and other cables on the support. This also reduces construction costs and time. The aforementioned stress analysis process confirms the practicality and reliability of the hanger 1 and the integrated cable support using it.

[0073] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
