Abstract
Description
Technical Field
[0001] This utility model relates to flexible steel wire rope nets for slope protection, and more particularly to steel wire ropes for slope protection nets that can monitor stress status in real time, belonging to the field of metal product manufacturing, processing and application. Background Technology
[0002] Traditional slope protection nets using steel wire ropes cannot monitor their own stress state or detect potential hazards in a timely manner. Existing nets requiring separate sensor configurations can monitor their stress state, but because these sensors are mostly installed and debugged in remote mountainous areas, they suffer from poor interference resistance, high failure rates, and difficulties in maintenance and troubleshooting, increasing operation and maintenance costs. Therefore, this paper proposes a steel wire rope for slope protection nets that can meet monitoring requirements and resist sensor data interference, and applies it to such nets. Utility Model Content
[0003] The purpose of this utility model is to provide an intelligent monitoring steel wire rope for slope protection nets. By changing the internal structure of the steel wire rope, it can transmit monitoring data in real time, monitor the stress state of the protection net in real time, improve safety and enhance anti-interference ability, reduce failure rate and save installation and maintenance costs. This utility model has the characteristics of simple structure, easy manufacturing and convenient installation, and is suitable for large-scale promotion and application.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0005] 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 sensor analyzer. The steel wire rope and the internal optical fiber of the intelligent protection net are connected to the FBG optical fiber sensor analyzer, which can interpret changes in optical fiber signals, via wires. The optical fiber sensor analyzer is connected to a wind power module or a solar power module to form an intelligent protection net monitoring and early warning system. The steel wire rope is fixed to a fixing device with a pressure plate, and a grid mesh is laid on the steel wire rope.
[0006] The beneficial effects of adopting the above technical solution are:
[0007] 1. This 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. By interpreting changes in the optical fiber signal within the carbon fiber optical fiber composite rod, the stress state of the slope protection net can be monitored in real time. This allows for the early detection of potential hazards in the protection net, significantly improving its safety.
[0008] 2. This utility model has steel wire protection on the outside of the optical fiber, which enhances the anti-interference ability of the optical fiber, reduces the failure rate, and thus saves maintenance costs.
[0009] 3. The installation process of this utility model's intelligent steel wire rope protective net reduces the steps of installing and debugging sensors, making the installation process more convenient and maintenance simpler.
[0010] 4. Users of this utility model can remotely monitor the protective netting in real time via APP mobile phone and PC computer, which helps to realize real-time monitoring and intelligent management of slopes. Attached Figure Description

Detailed Implementation
[0017] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0018] This utility model provides an intelligent monitoring steel wire rope for slope protection nets, and the specific implementation methods are divided into two types according to the technical solution:
[0019] Example 1:
[0020] The steel wire rope consists of a transverse support rope 3 and a longitudinal support rope 4, and is combined with the anchor rod 1 fixed to the slope to form an intelligent protective net. The intelligent protective net is connected to the internal optical fiber 9 and the FBG fiber optic sensor analyzer 10, which can interpret the changes in the optical signal of the optical fiber 9, through wires. The fiber optic sensor analyzer 10 is connected to a wind power module or a solar power module 11 to form an intelligent protective net monitoring and early warning system. The anchor rod 1 is equipped with a heart-shaped ring 1-1 and a steel wire rope sleeve 1-2. The steel wire rope sleeve 1-2 is equipped with a transverse support rope 3 and a longitudinal support rope 4. The transverse support rope 3 is fixed to the anchor rod 1 with a pressure plate. A grid mesh is laid on the support rope to form a protective net.
[0021] Example 2:
[0022] The steel wire rope is a horizontal support rope 3, which, together with the posts 1-3 fixed to the ground, forms an intelligent protective net. The intelligent protective net is connected to the internal optical fiber 9 and the FBG fiber optic sensor analyzer 10, which can interpret the changes in the optical signal of the optical fiber 9, through wires. The fiber optic sensor analyzer 10 is connected to a wind power module or a solar power module 11 to form an intelligent protective net monitoring and early warning system. The horizontal support rope 3 is fixed to the upper end of the posts 1-3, and the horizontal support rope 3 is fixed to the posts 1-3 with pressure plates. A grid mesh is laid on the support rope to form a protective net.
[0023] In the two embodiments described above, the transverse support rope 3 and the longitudinal support rope 4 are selected according to Embodiment 1.
[0024] According to Example 2, a transverse support rope 3 is selected. The implementation of the support rope in Examples 1 and 2 is as follows:
[0025] The transverse support rope 3 is composed of multiple outer layer filaments 5, multiple inner layer filaments 12 and a carbon fiber optical fiber composite rod 7 from the outside to the inside; the longitudinal support rope 4 is composed of multiple outer layer filaments 5, multiple inner layer filaments 12 and a rope core 6 from the outside to the inside; the carbon fiber optical fiber composite rod 7 is located at the center of multiple inner layer filaments 12, and the multiple outer layer filaments 5 and inner layer filaments 12 are twisted around the carbon fiber optical fiber composite rod 7. The carbon fiber optical fiber composite rod 7 includes composite carbon fiber 8 and optical fiber 9 disposed in the composite carbon fiber 8.
[0026] More specifically, the longitudinal support rope 4, as... Figure 5 As shown, the required longitudinal support rope 4 is formed by twisting two layers, consisting of 9 outer layer filaments 5 and 9 inner layer filaments 12, with the rope core 6 as the center, through a twisting device.
[0027] More specifically, the lateral support rope 3, as... Figure 4 As shown, the structure is divided into two layers by nine outer layer wires 5 and nine inner layer wires 12, with a carbon fiber composite rod 7 as the center, replacing... Figure 5 The rope core 6 in the middle is twisted by a twisting device to form the required transverse support rope 3.
[0028] Preferably, when producing a transverse support rope 3 with a diameter of 16mm and a structure of 1X19S (1+9+9), a carbon fiber optical fiber composite rod 7 with a diameter of 4mm is used to replace the rope core 6, and the required transverse support rope 3 is formed by twisting the rope using a twisting device.
[0029] The installation method for slope protection nets fixed to the slope surface is the same as that for slope protection nets fixed to ground posts. The slope protection net fixed to the slope surface (Example 1) uses pressure plates to fix the transverse support ropes 3 to the slope anchor rods 1, while the slope protection net fixed to ground posts (Example 2) uses pressure plates to fix the transverse support ropes 3 to the ground posts 1-3. Ultimately, the installation of longitudinal support ropes 4 is determined based on the specific requirements. During the use of the intelligent protection net, it performs protective operations and provides real-time monitoring and early warning, just like a traditional protection net.
[0030] The common mesh sizes of intelligent protective nets are 300×300mm and 400×400mm, and the common mesh sizes are 4×4m and 4×5m. Different mesh sizes can be selected according to the size of falling rocks and protection requirements.
