Description

Technical Field

[0001] This invention belongs to the field of cable installation component technology, and more specifically, relates to a direct-lay cable installation component for extremely cold environments. Background Technology

[0002] In extremely cold regions, ambient temperatures are generally below -20°C, and in some extreme cases, can reach below -40°C. Such low temperatures cause significant degradation of the physical properties of cable sheath materials (such as polyvinyl chloride (PVC) or polyethylene (PE), specifically a sharp decrease in toughness and a significant increase in hardness, causing the sheath to lose its flexibility and become rigid. Traditional cable support designs are not adapted to extremely cold environments, and their fixing clips or binding installation methods cannot effectively alleviate stress problems under low-temperature conditions.

[0003] When cables are left stationary for extended periods, stress concentration areas easily form at fixing points and bends, causing micro-cracks in the sheath that gradually expand and eventually lead to sheath cracking or brittle fracture. Simultaneously, frost easily forms between the cable sheath and the ground or insulation layer in low-temperature, high-humidity environments. Water vapor freezes into ice, firmly adhering the cable to the contact surface. Subsequent environmental disturbances (such as wind or temperature fluctuations) cause relative displacement between the cable and the adhered surface. Since the sheath has become brittle, it is highly susceptible to tearing damage. Furthermore, ice accumulation on the cable surface not only increases the mechanical load, putting greater pressure on the support structure, but also exacerbates the corrosive effect of low temperatures on the sheath material, further amplifying the risk of damage. Low temperatures also cause the sheath material to shrink, tightly binding with the internal conductors. When temperatures fluctuate, the thermal expansion and contraction of the conductors cannot be released through the sheath, generating internal stress that can also easily cause sheath tearing.

[0004] In summary, existing technologies cannot effectively solve the problem of cable damage in extremely cold environments. Therefore, a direct-lay cable installation component for extremely cold environments is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a direct-lay cable installation assembly for extremely cold environments to solve the problems mentioned in the background art.

[0010] Furthermore, a heating wire is provided in the mounting box for adjusting the damping strength of the spring, and a position sensor is installed in the mounting box for monitoring the sliding position of the mounting box and controlling the heating temperature of the heating wire.

[0028] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0029] 1. This extreme cold environment direct-lay cable installation assembly, through a damping structure consisting of a sliding lower clip plate and a spring, allows the cable to produce a small, controllable sway under environmental disturbances such as wind. This avoids stress concentration caused by traditional fixed installations and reduces the problem of unrelieved stress concentration caused by cable hardening due to low temperatures. This dynamic displacement can gradually release the accumulated stress at fixed points and bends, preventing micro-cracks from spreading and causing sheath cracking or brittle fracture. At the same time, the swaying can also break the thin ice on the cable surface, reducing the cable's additional weight and thus alleviating the problem of cable sagging and stress concentration at bends caused by low-temperature hardening, thereby mitigating cable damage. It also prevents ice from firmly adhering the cable to the contact surface, causing cable displacement and sheath tearing damage. In addition, the sliding structure and damping design provide displacement compensation space for thermal expansion and contraction of the cable, preventing the sheath from tearing due to internal stress caused by temperature fluctuations after the sheath and core are "locked in".

[0030] 2. This direct-lay cable installation assembly for extremely cold environments is designed so that the cable can sway according to wind conditions. It also features a support rod at the offset direction that automatically engages with the ground, creating an upward lifting force and a triangular support zone on the offset side. This enhances the stability of the cable installation assembly, preventing it from tipping over due to wind and achieving a synergistic protection between dynamic cable protection and structural stability. Simultaneously, the symmetrically arranged support rods within the base can divide and guide airflow in the unsupported state, preventing the formation of vortices and increased wind pressure at the base, reducing lateral load on the base, and indirectly minimizing additional stress on the cable caused by support swaying.

[0031] 3. The heating wires installed in the mounting box of this extreme cold environment direct-lay cable assembly can adjust the temperature of spring one according to the ambient temperature and operating status, so as to avoid excessive spring rigidity and damping failure caused by extreme cold. Combined with the slider displacement, offset frequency, dwell time and other parameters monitored by the position sensor, the heating temperature is dynamically adjusted through multi-condition control logic to ensure that spring one always maintains appropriate damping characteristics, taking into account both buffering effect and reset capability.

[0032] 4. This direct-lay cable installation component for extremely cold environments has developed differentiated temperature control strategies for different working conditions such as light wind, stable strong wind, overtravel risk, variable wind direction, and long-term stationary conditions. It not only ensures basic insulation and anti-stiffness in light wind, but also achieves enhanced damping in strong wind, limit protection in overtravel, and smooth buffering in variable wind direction, thus solving the problem that a single damping design cannot adapt to complex extremely cold working conditions.

[0033] 5. This direct-lay cable installation assembly for extremely cold environments uses an angle sensor to monitor the angle between the support rod and the ground, forming a collaborative correction mechanism with the slider displacement to perform secondary correction of the heating wire temperature. When the support rod provides effective mechanical support, it intelligently reduces the heating temperature to achieve energy saving; when the support is insufficient or the displacement is large, it maintains a reasonable heating intensity to ensure damping, achieving synergistic optimization of mechanical support and damping control.

[0034] 6. In this extreme cold environment direct-lay cable installation assembly, the symmetrical support rods, at their initial angle, do not contact the ground at their front ends. At this time, the symmetrical support rods in the base can be used to guide the airflow direction, preventing the airflow from forming eddies and superimposed wind pressure at the base, thereby effectively reducing the lateral load on the base. In addition, when the cable is displaced, the support rod on the displacement side changes to a single-sided support state, providing support force for the installation assembly when the center of gravity changes, while the support rod on the other side rises accordingly, moving the front end away from the ground. This prevents the accumulation of snow, ice, and frost between the front end and the ground in windy weather, which could cause the cable to stick to the ground and lead to the failure of the dynamic single-sided support.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0049] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 The technical solutions provided in the various embodiments of the present invention will be described in detail.

[0050] Example: Refer to Figures 1-7 An installation assembly for direct-lay cables in extremely cold environments includes a base 1, and further includes: an installation box 11, mounted on the base 1; a lower latch plate 2, slidably mounted on the installation box 11, with an upper latch plate 22 mounted on the lower latch plate 2 and forming an installation groove 21 for installing cables, the lower latch plate 2 and the installation box 11 are connected by a spring 14 to provide damping when the lower latch plate 2 slides; and support rods 34, symmetrically arranged on both sides inside the base 1. When the lower latch plate 2 moves to one side on the installation box 11, the front end of the support rod 34 on that side abuts the ground and forms a triangular support area 5, while the front end of the support rod 34 on the opposite side rises to form a dynamic unilateral force support.

[0051] For ease of understanding, the following explains some key terms in this embodiment:

[0052] The base 1 is the foundational structure of the entire mounting assembly, used to support other components and connect to the ground or mounting surface. It is designed to provide stable support to withstand external loads in extremely cold environments.

[0053] The mounting box 11 is mounted on the base 1, and its internal space is used to accommodate and protect other functional components, and to provide guidance and support for the sliding of the lower snap plate 2;

[0054] The lower clip plate 2 is a key component for fixing cables. It can slide on the mounting box 11. This sliding design is designed to provide a certain displacement space for the cables to adapt to thermal expansion and contraction or external forces in extremely cold environments.

[0055] The upper clip plate 22 is mounted on the lower clip plate 2, and together they form the mounting groove 21. The mounting groove 21 is the direct load-bearing area for the cable, and its shape and size are designed to securely clamp the cable while avoiding excessive compression on the cable sheath.

[0056] Spring 14 is connected between the lower latch plate 2 and the mounting box 11. Its function is to provide adjustable damping force when the lower latch plate 2 slides. This damping force helps to buffer external impacts and control the displacement speed of the cable, thereby reducing the risk of cable damage.

[0057] The support rods 34 are symmetrically arranged on both sides of the base 1. Their main function is to provide dynamic ground support according to the displacement of the lower buckle plate 2. When the component is subjected to lateral force, the support rods 34 can adjust their contact state with the ground to enhance the overall anti-overturning ability.

[0058] The triangular support zone 5 refers to the stable support area formed by the support rod 34, the base 1, and the ground when the front end of the support rod 34 touches the ground. This area can effectively disperse the force and improve the local stability of the component.

[0059] Dynamic unilateral force support refers to a situation where, when the component is subjected to a lateral force causing the lower latch plate 2 to shift to one side, the support rod 34 on that side forms a triangular support area 5, while the front end of the support rod 34 on the opposite side rises. This changes the component's support state from double-sided support to unilateral support dominated by the force-bearing side. This dynamic adjustment mechanism aims to adapt to changes in the external environment and maintain the overall stability of the component. It is important to understand that, referring to... Figure 3 When the support rod 34 is parallel to the base 1, the front end of the support rod 34 protrudes beyond the ground of the base 1. This means that when the front end of the support rod 34 touches the ground to provide support for the entire mounting assembly, the force of the front end of the support rod 34 touching the ground will cause the base 1 on that side to have a process of being "lifted", thereby providing additional support for the mounting assembly.

[0060] This embodiment provides a direct-lay cable installation assembly for extremely cold environments. Its basic structure includes a base 1, which can be designed to have the strength and stability to meet the load-bearing requirements. For example, it can be made of metal sheet or high-strength composite material, and can be directly fixed to the ground or wall by bolts, welding or adhesive to ensure the stability of the entire assembly.

[0061] An installation box 11 is installed on the base 1. The installation box 11 can be formed by one-piece molding or by assembling multiple parts. Its material can be low-temperature resistant and impact-resistant engineering plastic or metal. The installation box 11 can be connected to the base 1 by screw fastening, snap-fit ​​connection or welding to ensure its reliability in extremely cold environments.

[0062] A lower latch plate 2 is slidably mounted on the mounting box 11. The sliding of the lower latch plate 2 can be achieved in various ways. For example, a guide rail with a low friction surface can be provided on the inner wall of the mounting box 11, and a corresponding sliding groove can be provided on the bottom of the lower latch plate 2, so that the lower latch plate 2 can move linearly along the guide rail. Alternatively, a slide block with a low coefficient of friction can be installed on the bottom of the lower latch plate 2, which can slide directly on the flat surface of the mounting box 11.

[0063] The lower clip plate 2 is fitted with an upper clip plate 22, which together form a mounting groove 21 for installing cables. The upper clip plate 22 can be connected to the lower clip plate 2 by bolts to form an openable structure for easy insertion and removal of cables. Alternatively, the upper clip plate 22 can be made of an elastic material to hold the cables by its own elastic deformation. The inner wall of the mounting groove 21 can be designed with an arc-shaped structure or anti-slip texture to better adapt to the shape of the cables and prevent the cables from falling off during sliding.

[0064] The lower latch plate 2 is connected to the mounting box 11 by a spring 14, which provides damping when the lower latch plate 2 slides. The spring 14 can be in the form of a coil spring, leaf spring or torsion spring, etc., and its two ends are fixed to the inner walls of the lower latch plate 2 and the mounting box 11 respectively. When the cable is subjected to external force and the lower latch plate 2 is displaced, the extension or compression of the spring 14 will generate a force opposite to the direction of displacement, thereby achieving buffering and slowing down the sliding. The stiffness of the spring 14 can be selected according to the characteristics of the cable and the design damping effect.

[0065] Support rods 34 are symmetrically arranged on both sides inside the base 1. These support rods 34 can be made of metal rods or high-strength composite material rods and are installed on the base 1 by means of hinge or rotation connection. In the initial state, the support rods 34 can be stored inside the base 1 and do not contact the ground.

[0066] When the lower buckle plate 2 moves to one side on the mounting box 11, the front end of the support rod 34 on that side touches the ground and forms a triangular support area 5, while the front end of the support rod 34 on the opposite side rises, forming a dynamic unilateral force support; thus, the support rod 34 can dynamically adjust its contact point with the ground and its support method according to the external force conditions, so as to enhance its anti-overturning ability under specific environmental conditions such as extreme cold and strong winds.

[0067] A guide rod 12 is installed in the mounting box 11. A fixing block 13 is installed in the middle of the guide rod 12. Slider 15s are symmetrically installed at the bottom of the lower buckle plate 2. Both sliders 15 are slidably connected to the guide rod 12 and are located on both sides of the fixing block 13. Springs 14 are respectively connected between the slider 15 and the end wall of the mounting box 11, and between the slider 15 and the fixing block 13.

[0068] Therefore, after the device is installed on the ground or mounting surface via the base 1, the cable is installed between the lower clip plate 2 and the upper clip plate 22, leaving a certain gap between adjacent mounting components. The cable within this gap is in a suspended state. When there is wind, the cable is subjected to force, causing the lower clip plate 2 and the upper clip plate 22 to shift on the mounting box 11. The spring 14 provides displacement damping and reset force, which causes the cable to sway. The small-amplitude swaying generates vibration through the slight displacement of the cable itself, which can quickly shake off the frost and thin ice adhering to the surface, avoiding two major problems caused by the continuous accumulation of ice. First, it reduces the direct compression and erosion of the low-temperature brittle sheath by the ice layer, delaying the aging and cracking of the sheath. Second, it reduces the load on the cable caused by the extra weight of the ice layer, indirectly alleviating the stress concentration at the fixing point. In addition, the small-amplitude swaying of the cable can break the freezing stress on the contact surface, avoiding the accumulation of "static adhesion" in traditional fixed installations, which can lead to subsequent problems. To prevent sheath tearing caused by forced pulling during maintenance or environmental disturbances, the system reduces the risk of secondary damage during operation and maintenance. Simultaneously, the cable's swaying is not an isolated movement, but rather a linkage between cable displacement and the rotation of the support rod 34, causing its front end to contact the ground. When the cable shifts to one side due to strong winds, the support rod 34 forms an additional triangular support area 5 on the mounting component, offsetting lateral loads and preventing the base 1 from separating from the ground and tipping over. The stable support of the base 1 also protects the low-temperature, brittle cable from twisting, bending, and breaking due to the base 1 tipping over, achieving synergistic protection of dynamic cable protection and stable support structure. Furthermore, by setting a sliding lower latch plate 2 and a damping spring 14, the system effectively alleviates stress concentration, cracking, and brittle fracture of the cable sheath caused by low-temperature brittleness and thermal expansion and contraction in extremely cold environments, and avoids the risk of the cable sticking and tearing to the mounting surface. Meanwhile, through the dynamic unilateral force support mechanism of the support rod 34, the component can automatically adjust the support state according to the external force, effectively improving the overall stability under specific environmental conditions such as extreme cold and strong winds, thus effectively solving the technical problems of cable damage and insufficient stability of traditional brackets in extreme cold environments.

[0069] In addition, windproof plates 23 can be installed at both ends of the lower clip plate 2 to increase the contact area with the wind, so that the cable can keep swaying and further improve the protection of the cable.

[0070] In addition, refer to Figure 1 , Figure 3 , Figure 4The support rod 34 is installed inside the base 1. Initially, the support rod 34 is inclined, and the two sets of support rods 34 form a V-shape. When wind blows towards the base 1, the support rod 34 can directly block and divide the airflow. Furthermore, in extremely cold regions, winds are often crosswinds / turbulent flows, and the support rod 34 inside the base 1 can effectively guide the disordered airflow in a directional manner. Therefore, the design of the support rod 34's position can divide the strong winds that would otherwise impact the base 1 into multiple weaker flows, and guide the airflow to the sides and bottom of the base 1, preventing the formation of vortices and superimposed wind pressure at the base 1. This effectively reduces the lateral load on the base 1, indirectly reducing the additional stress on the cable caused by the swaying of the base 1. Moreover, the airflow direction guided by the support rod 34 can optimize the airflow field around the base 1, reducing the intensity of turbulence blowing towards the cable, allowing the cable to maintain only a small, controllable sway, thus achieving stress release, defrosting, and anti-sticking, while avoiding secondary damage caused by excessive swaying.

[0071] When the cable shifts and the support rod 34 is supported on one side, the support rod 34 in the opposite direction will rise. This design allows the support rod 34 on the corresponding side to touch the ground and form a rigid support point for any displacement of the cable to the left or right, thus offsetting the lateral load in that direction. The support rod 34 on the other side will not interfere. Moreover, the support rod 34 after rising is far away from the ground, avoiding adhesion to the ice or frozen soil on the ground. At the same time, the rising support rod 34 can reduce the obstruction of airflow on the ground, avoid the formation of wind pressure superposition at the bottom of the support, further reduce wind load, and achieve structural balance of force on the supported side and unloading on the non-supported side.

[0072] In extremely cold regions, manual maintenance is difficult and risky. The linkage action of the symmetrical support rod 34 is entirely driven by cable displacement, eliminating the need for manual angle adjustment. Furthermore, the "touch and lift" action can dynamically clean the support rod 34 itself. The slight contact between the support rod 34 and the ground can scrape off the ice accumulated at the front end of the rod, while the swing of the upward support rod 34 can shake off the frost on the surface of the rod, preventing the rod from freezing due to ice accumulation and ensuring the long-term reliable operation of the device in extremely cold environments without maintenance.

[0073] In some implementations, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The mounting box 11 has sliding grooves 110 at both ends of its bottom. A connecting rod 3 is slidably connected in each of the two sliding grooves 110. One end of the connecting rod 3 is connected to the slider 15, and a rack 31 is installed at the other end of the connecting rod 3. Gears 32 are rotatably connected to both sides of the base 1. The two racks 31 are respectively meshed with the corresponding gears 32. The end of the support rod 34 is fixedly connected to the connecting shaft 33 on the gear 32.

[0074] Through the above technical solution, this device constructs a precise gear and rack transmission mechanism, effectively solving the problem of inaccurate and unreliable linkage between the displacement of the lower latch plate 2 and the movement of the support rod 34. When the lower latch plate 2 is displaced on the mounting box 11, this displacement drives the rack 31 to move linearly through the connecting rod 3. The rack 31 meshes with the gear 32 on the base 1, converting the linear motion into precise rotation of the gear 32. Subsequently, the gear 32 drives the support rod 34 to swing through the connecting shaft 33. This mechanical linkage ensures that the support rod 34 can adjust its posture in a timely and accurate manner according to the actual displacement of the lower latch plate 2, achieving precise contact with the ground or upward movement. This not only improves the sensitivity and accuracy of the support rod 34's response but also enhances the entire assembly's ability to provide stable and reliable dynamic unilateral force support in extremely cold environments, thereby significantly improving the overall adaptability and operational stability of the cable installation assembly.

[0075] Among the aforementioned implementations, a direct-lay cable installation assembly for extremely cold environments has been proposed, which drives the movement of the support rod 34 by sliding the lower clip plate 2. However, in practical applications, especially in extremely cold environments, it may be necessary to make more precise adjustments to the support state of the support rod 34 or provide additional buffering and pre-tightening force to cope with the complex stress conditions under different working conditions, and avoid impact or inaccurate positioning caused by direct transmission, thereby affecting the stability and reliability of the support rod 34.

[0076] In some embodiments, a heating wire is provided in the mounting box 11 to adjust the damping strength of the spring-14, and a position sensor 16 is installed in the mounting box 11 to monitor the sliding position of the mounting box 11 and control the heating temperature of the heating wire.

[0077] Specifically, the main function of the heating wire is to provide heat to the spring 14 to regulate its temperature, thereby affecting its physical properties, especially its elastic modulus and damping strength. The heating wire can be arranged in the mounting box 11 in various forms. For example, it can be wound around the spring 14, or attached to the inner wall of the mounting box 11 in the form of a sheet or strip, close to the spring 14. Its power supply and control can be realized through an external power supply and control unit, and heating is performed according to the preset temperature or environmental conditions.

[0078] The position sensor 16 is a device for detecting the position or displacement of an object. In this device, it monitors the sliding position of the slider 15 at the bottom of the mounting box 11. By acquiring the real-time position information of the mounting box 11, it can provide key inputs for subsequent finger-based logic; for example, the operating status of the system can be determined based on the position information, and the heating temperature of the heating wire can be adjusted accordingly. The position sensor 16 can employ various technologies, such as optical sensors, magnetic sensors, or capacitive or inductive sensors. It measures displacement by sensing changes in capacitance or inductance. These sensors typically output an electrical signal that is proportional to the sliding position of the mounting box 11 and is transmitted to the control unit for processing.

[0079] Through the above technical solution, this device can effectively solve the problem of unstable damping characteristics of spring-14 in extremely cold environments. When the ambient temperature is too low, the heating wire can heat spring-14 to maintain its temperature within a suitable working range, thereby ensuring that the elastic modulus and damping strength of spring-14 remain stable and that the sliding damping effect of the lower clip plate 2 is always at its best. At the same time, the position sensor 16 monitors the sliding position of the mounting box 11 in real time, providing precise feedback for the temperature control of the heating wire. For example, when the mounting box 11 slides to a specific position, different damping strengths may be required. The feedback from the position sensor 16 can enable the heating wire to make precise temperature adjustments according to the actual working conditions, avoiding overheating or underheating, thereby achieving dynamic and precise control of the damping strength of spring-14. This not only improves the adaptability and reliability of the cable installation assembly in extremely cold environments, but also extends the service life of spring-14, ensuring the stable operation of the entire assembly under various working conditions and the safe fixation of the cable.

[0080] In extremely cold environments, the damping characteristics of spring 14 in the direct-lay cable installation assembly will change due to low temperatures, causing instability in the sliding resistance of the lower clip plate 2, which in turn affects the cable fixing effect and the dynamic support response of the support rod 34. Although the heating wires installed in the mounting box 11 can adjust the damping strength of spring 14 and control the heating temperature by monitoring the sliding position through the position sensor 16, if the heating control strategy is too simple or inaccurate, it may not be able to effectively cope with the complex and ever-changing external environment and internal operating conditions, resulting in insufficient heating or overheating, affecting system stability and energy efficiency.

[0081] To address this, a control logic for temperature regulation of the heating wire based on the position sensor 16 is further proposed. This control logic aims to dynamically adjust the target temperature of the heating wire based on parameters such as the real-time displacement X, offset frequency f, and residence time t of the slider 15 monitored by the position sensor 16 in the mounting box 11. Its function is to ensure that spring 14 maintains appropriate damping characteristics under different operating conditions, thereby ensuring stable sliding of the lower latch plate 2 and reliable support of the support rod 34. This logic achieves refined management of the heating process through multiple preset operating condition judgments and corresponding temperature calculation formulas. This control logic can be implemented using a microcontroller (MCU) or a programmable logic controller (PLC). By reading sensor data, performing corresponding calculations, and outputting a PWM signal to control the power of the heating wire, it regulates the temperature.

[0082] Specifically, the control logic includes the following steps:

[0083] First, under light or no wind conditions, when the real-time displacement X of slider 15 satisfies When the displacement is less than or equal to the slider's 15 safe stroke threshold. At 20% of the target temperature of the heating wire Set as ambient temperature Add a small fixed increment, i.e. This strategy aims to keep the damping of spring-14 constant and provide basic insulation for spring-14, preventing spring-14 from becoming excessively stiff due to extreme cold, which would cause stress concentration when the cable vibrates slightly, while avoiding unnecessary energy consumption.

[0084] Secondly, under stable high wind conditions, the temperature decreases, and when the real-time displacement X of slider 15 satisfies... And the offset frequency f satisfies At that time, the cable was subjected to a relatively large but stable wind force, causing the displacement of slider 15 to be within a moderate range, and the offset frequency f to be lower than the frequency threshold. At that time, the target temperature of the heating wire The calculation formula is: The correction factor The value ranges from 0.6 to 1.0. Under these conditions, the system requires stronger damping to resist displacement caused by wind. Therefore, the heating temperature setting takes into account the magnitude of position X and is adjusted by a correction term that is negatively correlated with position X. This ensures the damping effect of the spring-14 while preventing overheating from affecting cable displacement; thus, it allows the cable to sway stably within a small range, thereby reducing damage to the cable.

[0085] Furthermore, under the risk of overtravel (overtravel, i.e., exceeding the safe displacement stroke of slider 15), when the real-time displacement X of slider 15 satisfies... And the offset frequency f satisfies When the displacement of slider 15 approaches the safe travel threshold. However, the offset frequency f is still below the frequency threshold. At that time, the target temperature of the heating wire Set as ambient temperature Add a small fixed increment, i.e. This indicates that the cable may face the risk of overtravel. Reducing the heating amplitude and slightly increasing the damping of spring 14 will suppress further displacement of slider 15, avoid the risk of overtravel, and thus effectively improve the protection of the cable and prevent cable damage.

[0086] Furthermore, under conditions of variable wind direction, when the offset frequency f satisfies At that time, the wind direction changed frequently, causing the offset frequency f of slider 15 to exceed the frequency threshold. Yes, the target temperature of the heating wire. The calculation formula is: The correction factor The value ranges from 0.5 to 0.8. Under these conditions, the cable frequently changes direction when the wind direction changes, and the cable is heated to the target temperature. This ensures that spring 14 maintains appropriate rigidity, preventing excessive damping that could cause severe cable swaying. It also accommodates the buffering needs of frequent displacements and prevents cable damage caused by low temperatures leading to cable stiffness and stress concentration under varying wind conditions.

[0087] Finally, under the condition of long-term residence of slider 15, when the residence time t satisfies And the real-time displacement X of slider 15 satisfies X When, i.e., slider 15 is close to the safe travel threshold When the heating wire remains in the position for an extended period of time, the target temperature of the heating wire The calculation formula is: The correction factor The value ranges from 0.5 to 1.0. Prolonged stagnation may indicate that the cable is continuously subjected to high loads or is jammed, requiring a special heating strategy. In this case, the target temperature of the heating wire... The setting takes into account the residence time t, and is adjusted by a correction term that is negatively correlated with the residence time t. If slider 15 remains near the overtravel position for an extended period, the heating temperature should be appropriately reduced. The damping of spring 14 should be increased to force a limit reset, while simultaneously preventing the spring 14 from becoming brittle due to excessively low temperatures.

[0088] in, The target temperature for the heating wire. For ambient temperature, For the real-time displacement of slider 15, The safe travel threshold for slider 15. The offset frequency of slider 15, For frequency threshold, The dwell time of slider 15. The dwell time threshold, These parameters, acting as correction factors, are used in the control logic to calculate the target temperature of the heating wire. The key variables reflect the stress on the cable and the dynamic behavior of the system.

[0089] Through the aforementioned heating wire temperature control logic, this device can adjust the temperature based on key parameters such as slider 15 displacement X, offset frequency f, and residence time t monitored in real time by position sensor 16, combined with ambient temperature. Intelligently adjust the target temperature of the heating wire Furthermore, different heating wire temperature control strategies are implemented under different operating conditions, ensuring that the damping characteristics of spring-14 remain in optimal working condition in extremely cold environments. This effectively solves the problem that traditional single heating strategies cannot adapt to complex and variable operating conditions, significantly improves the stability and reliability of cable installation components in extremely cold environments, optimizes energy utilization efficiency, and avoids the negative impacts of overheating or underheating.

[0090] To address this, this application proposes a direct-lay cable installation assembly for extremely cold environments. The temperature control logic of its heating wire can adjust according to ambient temperature under various operating conditions, including light winds, stable strong winds, overtravel risks, fluctuating wind directions, and prolonged stagnation of the slider 15. The target temperature of the heating wire is dynamically calculated based on parameters such as the real-time displacement X of slider 15, the offset frequency f of slider 15, and the residence time t of slider 15. However, in practical applications, especially in extremely cold and variable environments, the target temperature calculated solely based on these operating condition models is not reliable. There is a risk that if the temperature is too low, the heating effect will be insufficient, or if it is too high, energy will be wasted or even components will be damaged, which will affect the accuracy of the spring-14 damping adjustment and the overall reliability of the system.

[0091] To further optimize the temperature control of the heating wire, this device sets a target temperature for the heating wire. Explicit constraints were set: The unit is ℃;

[0092] This constraint limits the target temperature of the heating wire. The range of values ​​for . Specifically, the target temperature It must always be higher than the ambient temperature. At least 1°C is required to ensure the heating wire provides sufficient heat under any operating conditions, preventing spring-14 from failing or degrading due to low temperatures in extremely cold environments. Simultaneously, the target temperature... The ambient temperature must not exceed Adding 20°C is intended to prevent the heating wire from overheating. Overheating not only causes unnecessary energy waste but may also accelerate the aging of components such as spring-14, or even cause thermal damage to other sensitive components or cables in the mounting box 11, thereby affecting the long-term stability and reliability of the entire mounting assembly. This constraint, by setting a reasonable temperature range, ensures that the heating wire provides the necessary heat while avoiding potential overheating risks, thereby optimizing the system's energy efficiency and component lifespan.

[0093] By controlling the target temperature of the heating wire Set clear upper and lower limits to ensure that it is always higher than the ambient temperature. At least 1°C and not exceeding the ambient temperature By adding 20°C, this device effectively solves the problem that the target temperature calculated from the data monitored by the position sensor 16 may be too low or too high under complex working conditions. When the temperature is too low, this constraint ensures that the heating wire can still provide sufficient heat to maintain the normal damping characteristics of spring-14, preventing it from stiffening or failing due to excessively low temperatures under extremely cold conditions, thereby ensuring smooth sliding of the lower clip plate 2 and stability of cable installation. Conversely, when the calculated... When the temperature is too high, this constraint can prevent the heating wire from overheating, avoid energy waste, and protect the spring-14 and other components in the mounting box 11 from heat damage, thus extending the service life of the components. This bounded temperature control strategy makes the heating process of the heating wire more precise and efficient, and significantly improves the reliability, safety and energy efficiency of the entire direct-lay cable installation component in extremely cold environments while ensuring the functionality of the system.

[0094] In some of the embodiments described above in this application, a control logic is proposed to regulate the temperature of the heating wire based on parameters such as the real-time displacement, offset frequency, and dwell time of the slider 15. However, in practical applications, this control logic mainly focuses on the sliding characteristics inside the cable mounting assembly and fails to directly obtain the actual support state between the assembly and the ground, especially the contact angle information between the support rod 34 and the ground. This may result in the temperature regulation of the heating wire failing to fully take into account the overall structural stability of the assembly in extremely cold environments, thereby affecting its reliability under complex working conditions.

[0095] To address this, this application further proposes an improvement: by introducing real-time monitoring of the physical support state of the support rod 34, the temperature control of the heating wire can be optimized. Specifically, an angle sensor is installed at the gear 32 to monitor the rotation angle of the gear 32, thereby enabling the real-time measurement of the angle between the support rod 34 and the ground. .

[0096] By monitoring the rotation angle of gear 32, the extent of extension or retraction of support rod 34 can be accurately determined. The rotation of gear 32 directly drives the movement of support rod 34; therefore, its rotation angle has a direct geometric relationship with the pose of support rod 34. An angle sensor converts the mechanical rotation angle of gear 32 into electrical signals, which are then read and processed by the microcontroller or control unit inside the component.

[0097] Based on the rotation angle of gear 32, combined with the geometric dimensions of support rod 34 (such as length and installation point position) and preset parameters such as the relative height of base 1 to the ground, the angle between support rod 34 and the ground can be calculated in real time by establishing a geometric model or by looking up a table. This real-time angle This is a key indicator for evaluating whether the support rod 34 effectively contacts the ground and provides stable support. When the front end of the support rod 34 touches the ground and forms a triangular support area 5, the angle between it and the ground is... This is crucial for assessing the stability and effectiveness of the support.

[0098] By installing an angle sensor at gear 32 and monitoring its rotation angle, this device can obtain the angle between the support rod 34 and the ground in real time. This real-time angle This provides direct feedback information regarding the actual physical support status between the cable mounting assembly and the ground. Therefore, the control system no longer relies solely on the displacement of slider 15 and environmental parameters to regulate the heating wire temperature, but can instead combine this with the actual support condition of support rod 34 to achieve more precise and comprehensive control of the heating wire temperature. For example, when the included angle of support rod 34... When the system indicates that the support rod 34 fails to effectively contact the ground or is in an unstable state, it can adjust the temperature of the heating wire accordingly to ensure the smooth deployment of the support rod 34 or prevent freezing from affecting its support function. This significantly improves the overall structural stability and operational reliability of the cable installation assembly in extremely cold environments and effectively avoids potential risks caused by insufficient support.

[0099] In some of the above embodiments, it is proposed to adjust the damping strength of the heating wire-14 and control the target temperature of the heating wire based on the real-time displacement X of the slider 15 monitored by the position sensor 16 and environmental conditions. In addition, an angle sensor was introduced to monitor the rotation angle of gear 32, thereby obtaining the real-time angle between the support rod 34 and the ground. However, while this control strategy considers the dynamic displacement response of the cable and the angle information of the support rod 34, it has not yet coordinated the two to more comprehensively assess the overall stability of the component and optimize the temperature control of the heating wire. Controlling based solely on a single or independent parameter may result in unnecessary heating even when the support rod 34 provides sufficient mechanical support, leading to energy waste; conversely, when the support rod 34 provides insufficient support, the damping may not be adjusted in time, affecting the overall stability of the component.

[0100] To address this, this device further proposes a collaborative correction mechanism, which uses the real-time angle between the support rod 34 and the ground, as monitored by the angle sensor. The real-time displacement X of slider 15 monitored by position sensor 16 is correlated with the displacement X of slider 15, based on... The correlation with X affects the target temperature of the heating wire. Make corrections to obtain the corrected target temperature. ;

[0101] Specifically, this coordinated correction mechanism is implemented through a control unit that receives the real-time angle between the support rod 34 and the ground from the angle sensor. The control unit processes the data, including the real-time displacement X data of the slider 15 monitored by the position sensor 16, according to preset logic and formulas.

[0102] The mechanism first clarifies the support state and included angle of the support rod 34. Criteria for determining the relationship: when When the support rod 34 touches the bottom, it forms a support. If the support rod 34 is not in contact with the ground, it is determined that there is no support. To more precisely evaluate the support effect, this mechanism further defines the safe support range of the support rod 34 as follows: ,in The critical angle for the support rod to contact the ground is 34°. The effective support limit angle of support rod 34 means that within this range, support rod 34 not only touches the ground, but its support angle is also in a safe and efficient working state. Specifically, in the mechanical design of the installation assembly, the real-time angle between support rod 34 and the ground... Designed to decrease as the displacement X of slider 15 increases, this reflects the dynamic process by which support rod 34 gradually extends and provides support through mechanical linkage when the mounting assembly is subjected to external loads.

[0103] Based on this, the control unit adjusts the initial target temperature according to the following correction formula. The correction is made, and the correction formula is:

[0104] Formula (1),

[0105] The initial target temperature is calculated based on the aforementioned control logic (such as light wind conditions, stable strong wind conditions, overtravel risk conditions, wind direction change conditions, or long-term stagnation conditions of slider 15).

[0106] Correction coefficient and basic cooling range It is based on the real-time included angle of support rod 34 The real-time displacement X of slider 15 is dynamically calculated, where the correction coefficient is... The calculation formula is:

[0107] Formula (2),

[0108] This formula shows that, The value is supported by the support rod 34 (through) and , The relationship between the two is reflected in the displacement of slider 15 (via X and X). The relationship reflects the combined influence. The more effective the support of support rod 34 (…), the greater the impact. The closer Furthermore, the larger the displacement of slider 15 (the larger X), the greater the correction coefficient. The larger the value, the greater the temperature correction that can be performed.

[0109] Basic cooling range The calculation formula is:

[0110] Formula (3),

[0111] This formula primarily determines the basic cooling rate based on the real-time displacement X of slider 15. The larger X is, the lower the temperature drop. The larger the correction coefficient, the more important it is in practical applications. The value range is limited to 0.1~0.5, and the basic cooling range is... The value range is limited to 3~8℃ to ensure the rationality and safety of the correction. The final corrected target temperature... Must meet The constraint of ℃ means that the corrected temperature must still be higher than the ambient temperature. At least 1°C, and not exceeding the ambient temperature. Add 20°C to ensure that the heating wire can always provide the necessary damping adjustment capability, while avoiding overheating.

[0112] The above technical solution enables more precise and intelligent control of the target temperature of the heating wire. This collaborative correction mechanism fully considers the coupling effect between the dynamic displacement of the cable and the mechanical support state, avoiding the limitations that may arise from single-parameter control. When the support rod 34 provides effective and safe mechanical support, the system can intelligently reduce the target temperature of the heating wire, thereby reducing unnecessary energy consumption and achieving energy-saving operation. Simultaneously, this correction mechanism ensures that even with insufficient mechanical support or large cable displacement, the heating wire can still provide sufficient heating to adjust the damping of spring-14, thus maintaining the overall stability and safety of the assembly. This multi-parameter collaborative control strategy significantly improves the adaptability, reliability, and energy efficiency of direct-lay cable installation assemblies in extremely cold environments, enabling the assembly to maintain optimal operating conditions under various complex operating conditions.

[0113] In some embodiments, refer to Figure 5 , Figure 6 , Figure 7 An installation assembly for direct-lay cables in extremely cold environments is basically the same as the above embodiment, but further includes the following: a connecting frame 43 is installed on the base 1, a sleeve 44 is installed on the connecting frame 43, a second spring 46 is installed in the sleeve 44, a sliding plate 45 is slidably connected in the sleeve 44, and the second spring 46 is connected to the sliding plate 45; a second gear 41 is rotatably connected to the connecting frame 43, a lead screw 42 is threadedly connected to the second gear 41, the end of the lead screw 42 is fixedly connected to the sliding plate 45, and a rack 4 is installed on the connecting rod 3, which meshes with the second gear 41;

[0114] Specifically, the connecting bracket 43, as a structural component, is usually made of high-strength materials, such as metal alloys or engineering plastics. Its main function is to provide a stable mounting base for the sleeve 44 and gear 41, and to ensure the precise relative position of these components on the base 1. The connecting bracket 43 can be firmly fixed to the base 1 by means of bolts, riveting or welding to withstand the forces and torques generated during transmission.

[0115] Sleeve 44 is a hollow guide structure whose internal space is designed to precisely accommodate and guide slide 45 to slide in a straight line. The inner wall of sleeve 44 is usually finely machined to ensure low friction and high stability when slide 45 moves within it. Its material can be wear-resistant metal or composite material to ensure reliability in long-term use and extreme cold environments.

[0116] Through the above technical solution, when the snap-on plate 2 slides, it drives the connecting rod 3 to move. The rack 4 on the connecting rod 3 meshes with the gear 41, converting the linear motion of the connecting rod 3 into the rotational motion of the gear 41. The rotation of the gear 41 drives the lead screw 42 to move up and down linearly through the threaded transmission, thereby driving the slide plate 45 to slide in the sleeve 44 and compressing or releasing the spring 46. This precise transmission chain introduces an adjustable buffer mechanism between the movement of the connecting rod 3 and the final position of the support rod 34. When the cable is displaced, the spring 14... In the lateral position, damping and restoring force are provided, while spring 2 46 provides a vertical force perpendicular to the lateral position, reducing the fluctuation caused by the force on spring 14, making the small amplitude sway of the cable more stable, and avoiding excessive fluctuation, which could cause the base 1 to fluctuate and cause the connection with the ground to fail. It can also ensure that the support rod 34 can more stably contact the ground and form support, which significantly improves the adaptability and reliability of the installation components in extremely cold environments, making the support action of the support rod 34 more stable and controllable, and avoiding the impact and positioning errors that may be caused by direct transmission.

[0117] It is important to note that during the actual installation process, a protective cover should be designed to prevent rain and snow from burying the installation components or freezing the structural parts.
