Description

Technical Field

[0001] The invention relates to the technical field of large-diameter cable laying construction system, in particular to a long-distance large-diameter cable laying construction system and a construction method in a cable trench. Background Art

[0002] The construction system for laying large-diameter cables over long distances in cable trenches usually includes traction devices, guide devices, and auxiliary equipment. The traction device is mainly used to provide continuous pulling force to lay large-diameter cables along the cable trench to the designated location. The guide device is used to prevent the cable from being twisted or damaged during the laying process, ensuring that the cable can smoothly enter the cable trench or pass through narrow bends. Auxiliary equipment, such as tension adjustment devices and cable support systems, are used to protect and stabilize the cables at different laying stages to prevent damage to the cables due to excessive bending or external forces. The working principle of the system is to enable large-diameter cables to be laid smoothly and safely over long distances through automated traction and precise guidance.

[0003] Although this construction system has certain advantages when laying large-diameter cables over long distances, it also has some drawbacks. Uneven traction can cause surface damage or internal damage to the cable, affecting the service life of the cable. When the system is laid in complex terrain, especially in narrow, curved or sloping cable trenches, uneven force on the cable is prone to occur, which increases the difficulty of construction. During long-distance laying, if there is no effective tension control mechanism, the cable may be overstretched or deformed due to uncontrolled tension, affecting the final construction quality. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a construction system and method for laying long-distance and large-diameter cables in cable trenches, which solves the problem that uneven traction force may cause surface damage or internal damage to the cable; without an effective tension control mechanism, the cable may be over-stretched or deformed due to uncontrolled tension.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a long-distance and large-diameter cable laying construction system in a cable trench, comprising:

[0006] The traction device is used to provide stable and adjustable pulling force during the cable laying process to ensure that the cable moves smoothly along the predetermined path;

[0007] The guide device is set at a key position in the cable laying path to prevent the cable from being twisted, deformed or damaged during movement. The surface of the guide wheel is made of polyurethane rubber, which has high friction and wear resistance.

[0008] The tension control system uses multiple tension sensors to monitor the cable tension changes at each laying stage in real time, and uses a closed-loop control algorithm to dynamically adjust the traction force;

[0009] The tension calculation model is used to calculate the traction force during cable laying. The formula is as follows:

[0010]

[0011] Where T is the traction force, W is the cable weight, L is the cable length, μ is the friction coefficient, g is the acceleration of gravity, θ is the path slope angle, Δh is the height difference, and Δx is the horizontal distance;

[0012] Cable support device, with multiple support points set along the cable laying path. The material of the support points is made of carbon fiber composite materials to reduce the weight of the device and enhance the strength, so that the force on the cable at different positions is uniform;

[0013] The control software system interacts with the data of sensors and traction devices. The built-in control algorithm optimizes the traction force distribution according to the real-time monitoring data to prevent uneven force or excessive stretching of the cable.

[0014] The laying path simulation model uses 3D simulation software to globally simulate and optimize cable laying based on the terrain data and cable properties of the laying path, and calculates and optimizes traction and guidance strategies in advance.

[0015] Preferably, the traction device includes a plurality of segmented traction units, and the traction force of each unit can be independently adjusted to adapt to different conditions of the laying path. The traction unit is connected to the central control system via wireless communication to provide real-time feedback of the traction force data of each segment.

[0016] Preferably, the guide device includes a guide wheel, which can adapt to the adjustment of the cable at different laying angles to avoid twisting or compression. The surface of the guide wheel is made of polyurethane rubber to ensure stable movement of the cable during laying and prevent wear.

[0017] Preferably, the tension sensor in the tension control system is based on optical fiber sensor technology, and can accurately measure the stress state of each point of the cable. The tension sensor can automatically identify abnormal tension and adjust the traction force distribution through control software.

[0018] Preferably, the control software system includes an artificial intelligence algorithm that can self-learn based on historical data to optimize traction and guidance strategies, and the simulation model can be updated in real time to adjust the laying strategy and traction distribution according to on-site feedback.

[0019] Preferably, the laying path simulation model uses machine learning to optimize the cable laying path, predict possible high tension points, and provide preventive measures. In the tension calculation formula, the friction coefficient μ can be dynamically adjusted according to the laying environment to adapt to cables of different materials and path conditions.

[0020] Preferably, the tension calculation formula also includes a compensation factor for calculating the additional tension requirement when there is a slope or curve section in the path. The control software system can remotely monitor the laying process and provide abnormal alarms and real-time adjustment suggestions.

[0021] The method for laying a long-distance large-diameter cable in a cable trench comprises the following steps:

[0022] a. Collect data such as the terrain, slope and curvature of the cable laying path, and input this information into 3D simulation software for path modeling.

[0026] e. Through the artificial intelligence algorithm built into the control system, traction and guidance control will be continuously optimized during the construction process. The artificial intelligence will automatically adjust the construction strategy based on historical data and real-time sensor feedback to ensure that the tension on the cable is evenly distributed during the entire laying process, further improving the safety and efficiency of construction;

[0027] f. The entire construction process is remotely monitored by the control software system. Any abnormal tension or guide error will trigger a system alarm. The operator can make real-time adjustments through the remote operating system to ensure that the parameters of the traction force and guide device are within a safe range, quickly solve the problem and prevent construction interruptions or accidents;
