Description

Technical Field

[0001] The present invention relates to a flexible steel wire rope net for slope protection, and particularly to a steel wire rope for a slope protection net capable of real-time monitoring of the stress state, belonging to the field of manufacturing, processing and application of metal products. Background Art

[0002] The traditional slope protection net using steel wire ropes cannot monitor its own stress state and cannot detect potential hazards in a timely manner. The existing protection nets that require separate sensor configurations can monitor the stress state of the protection net. However, since most of the slope protection nets are installed and debugged with sensors in the wilderness mountainous areas, the anti-interference ability is poor, the failure rate is relatively high, and the maintenance and troubleshooting operations are difficult, increasing the operation and maintenance costs. Therefore, a steel wire rope for a protection net that can meet the monitoring requirements and resist the interference of sensing data is designed and applied to the protection net. Summary of the Invention

[0003] The purpose of the present invention is to provide an intelligent monitoring steel wire rope for a slope protection net. By changing the internal structure of the steel wire rope, the monitoring data can be transmitted in real time, the stress state of the protection net can be monitored in real time, the safety is improved, the anti-interference ability is enhanced, the failure rate is reduced, and the installation and operation and maintenance costs are saved. The present invention has the characteristics of simple structure, easy production and convenient installation, and is suitable for large-scale popularization and application.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: An intelligent monitoring slope protection net includes a steel wire rope, an internal optical fiber of the intelligent protection net, and an FBG optical fiber sensing analyzer; the steel wire rope and the internal optical fiber of the intelligent protection net are connected to the FBG optical fiber sensing analyzer capable of interpreting the change of the optical fiber optical signal through a wire. The optical fiber sensing analyzer is connected to a wind power power module or a solar power module to form an intelligent protection net monitoring and warning system. The steel wire rope is fixed on the fixing device by a pressing plate, and a grid net is laid on the steel wire rope.

[0005] The beneficial effects of adopting the above technical solution are as follows: 1. The present invention uses a carbon fiber optical fiber composite rod to replace the traditional metal core or strand located in the center of the steel wire rope, and can monitor the stress state of the slope protection net in real time by interpreting the change of the optical fiber optical signal in the carbon fiber optical fiber composite rod. In this way, the hidden dangers existing in the protection net can be discovered in advance, and the safety of the protection net is significantly improved.

[0006] 2. The present invention has steel wire protection outside the optical fiber, which enhances the anti-interference ability of the optical fiber, reduces the failure rate, and thus saves the maintenance cost.

[0007] 3. The installation process of the intelligent steel wire rope protection net of the present invention reduces the process of installing and debugging sensors, the installation process is more convenient, and the maintenance is simpler.

[0008] 4. Users of the present invention can remotely and real - time monitor the protective net through the APP mobile terminal and the PC computer terminal, which helps to achieve real - time monitoring and intelligent management of the slope. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Embodiment 2: The steel wire rope is the lateral support rope 3, which combines with the column 1-3 fixed to the ground to form an intelligent protection net; the intelligent protection net is connected to the optical fiber 9 inside the intelligent protection net and the FBG optical fiber sensing analyzer 10 that can interpret the change of the optical signal of the optical fiber 9 through a wire; the optical fiber sensing analyzer 10 is connected to the wind power power module or the solar power module 11 to form an intelligent protection net monitoring and early warning system; the upper end of the column 1-3 fixes the lateral support rope 3 and the lateral support rope 3 is fixed to the column 1-3 by a pressing plate; a grid net is laid on the support rope to form a protection net.

[0017] In the above two embodiments, the lateral support rope 3 and the longitudinal support rope 4 are selected according to Embodiment 1.

[0018] The lateral support rope 3 is selected according to Embodiment 2. The realization of the support rope in Embodiment 1 and Embodiment 2 is as follows: The lateral support rope 3 is composed of multiple outer layer wires 5, multiple inner layer wires 12 and a carbon fiber optical fiber composite rod 7 from outside to inside; the longitudinal support rope 4 is composed of multiple outer layer wires 5, multiple inner layer wires 12 and a rope core 6 from outside to inside; the carbon fiber optical fiber composite rod 7 is at the center of multiple inner layer wires 12, and multiple outer layer wires 5 and inner layer wires 12 twist and wrap the carbon fiber optical fiber composite rod 7, and the carbon fiber optical fiber composite rod 7 includes composite carbon fiber 8 and the optical fiber 9 arranged in the composite carbon fiber 8.

[0019] More specifically, for the longitudinal support rope 4, as Figure 5 shown, it is divided into two layers by 9 outer layer wires 5 and 9 inner layer wires 12, centered on the rope core 6, and the required longitudinal support rope 4 is made by twisting and wrapping through a rope twisting device.

[0020] More specifically, for the lateral support rope 3, as Figure 4 shown, it is divided into two layers by 9 outer layer wires 5 and 9 inner layer wires 12, centered on a carbon fiber optical fiber composite rod 7, replacing Figure 5 the rope core 6 in, and the required lateral support rope 3 is made by twisting and wrapping through a rope twisting device.

[0021] Preferably, when producing the lateral support rope 3 with a diameter of 16 mm and a structure of 1X19S(1+9+9), a carbon fiber optical fiber composite rod 7 with a diameter of 4 mm is used to replace the rope core 6, and the required lateral support rope 3 is made by twisting and wrapping through a rope twisting device.
