Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, and in particular comprises a multi-stage coordinated mobile energy-consuming slope protection device. Background Art

[0002] Slope protection, a key technology for ensuring the harmonious coexistence of engineering structural safety and the ecological environment, is becoming increasingly important. With the continuous expansion and upgrading of road transportation networks, the stability of slopes, as the critical interface between mountain and road surface, is directly related to road capacity and driving safety. However, complex and changing geological conditions and the frequent occurrence of extreme climate events have made geological disasters such as slope collapse, rockfall, and landslides a major threat to road safety, causing not only huge economic losses but also serious threats to life and property.

[0003] Traditional slope protection methods, such as gravity retaining walls and anchor reinforcement, although they have played a protective role to a certain extent, are often limited by the singleness of their structural design and lack sufficient flexibility and adaptability, making it difficult to effectively respond to complex and changing geological disasters. Especially when faced with large-scale landslides or collapses, traditional protection methods often have a single energy consumption mechanism and limited effectiveness, making it difficult to quickly and efficiently disperse and consume the huge energy generated by geological disasters, thereby failing to effectively prevent the further expansion of the disaster. In view of this, it is particularly important to develop a slope protection device that can adapt to different geological conditions and has a multi-level coordinated and efficient energy consumption mechanism. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a multi-stage coordinated mobile energy-consuming slope protection device.

[0005] This multi-stage coordinated mobile energy-absorbing slope protection device comprises a protective grid, a mobile energy-absorbing anchor block and a buffer device. A rotating roller is vertically arranged in the center of the protective grid, and the mobile energy-absorbing anchor block and the rotating roller are connected by a linkage chain.

[0006] The buffer device is installed at the downhill end of the protective grid and includes a fixed column and an electrical box. The bottom of the fixed column is connected to the output shaft of the electrical box. The fixed column rotates vertically. A control chain is connected to the middle of the linkage chain, and the other end of the control chain is wrapped around the fixed column.

[0007] Preferably, the buffer device includes a fixed column, a transmission shaft and an electrical box. The bottom of the fixed column is connected to the transmission shaft, and the bottom end of the transmission shaft is connected to the output shaft of the electrical box. The electrical box is used to control the rotation speed of the fixed column.

[0008] Preferably, the rotating rollers and the movable energy-absorbing anchor blocks correspond to each other one by one, and several linkage chains are connected between the corresponding rotating rollers and movable energy-absorbing anchor blocks.

[0009] Preferably, the buffer device is installed between the protective grid and the movable energy-absorbing anchor block, and the installation position of the buffer device is higher than the connection position of the control chain and the linkage chain.

[0010] Preferably, a protective net is provided between adjacent protective grids to intercept the landslide.

[0011] The beneficial effects of the utility model are:

[0012] 1) The utility model forms a complete protection system by closely combining the protective grid, the mobile energy-absorbing anchor block and the buffer device, realizing a multi-level coordinated dispersion and dissipation mechanism of energy. The protective net and the protective grid can resist the impact through the strength of the structure itself, effectively intercept the landslide body and prevent it from further spreading, while the mobile energy-absorbing anchor block safely dissipates the remaining energy through the energy-absorbing mechanism, and further converts the remaining impact energy into kinetic energy and friction work, which greatly improves the protection effect and stability of the protective net. The buffer device controls the moving speed of the mobile energy-absorbing anchor block to ensure that the energy dissipation process is smooth and orderly, avoiding secondary damage to the protective grid and the protective net. The overall system has extremely high safety.

[0013] 2) This new protective net is constructed from high-strength, corrosion-resistant, and age-resistant carbon fiber, ensuring long-term stability and reliability. The robust frame structure and self-lubricating, wear-resistant rotating rollers ensure the device's durability in harsh environments. Furthermore, a multi-stage coordinated energy dissipation mechanism allows the device to adapt to landslides of varying sizes and intensities, providing a wider range of adaptability.

[0014] 3) The utility model significantly reduces the potential threat of natural disasters such as landslides and collapses to the surrounding ecological environment and human activities by effectively intercepting and dissipating the energy of the landslide body.

[0015] 4) The utility model has several linkage chains connecting the rotating rollers and the mobile energy-absorbing anchor blocks. The design takes into account the redundancy and maintainability of the system. The redundant design of the linkage chains ensures that the system can still operate stably when part of it is damaged. At the same time, the entire protective device has a clear structure, which is easy to carry out daily maintenance and inspection work, thereby reducing long-term maintenance costs.

[0019] The present invention will be further described below with reference to the following embodiments. The following embodiments are provided solely to facilitate understanding of the present invention. It should be noted that, within the scope of the present invention, modifications may be made by a person skilled in the art without departing from the principles of the present invention. Such improvements and modifications are also within the scope of the claims of the present invention.

[0020] Example 1

[0021] As an example, Figure 1 As shown, this multi-stage coordinated mobile energy-consuming slope protection device includes a protection device, an energy-consuming device and a buffer device 3.

[0022] The protective device includes a protective grid 101 and a protective net 102, ensuring effective coverage and support for the slope. In this embodiment, the protective net 102 is made of high-strength, corrosion-resistant, and age-resistant carbon fiber material, offering excellent flexibility and impact resistance, effectively intercepting landslides and preventing their further spread. The protective grid 101 is designed as a sturdy and durable frame structure, ensuring long-term reliability.

[0023] The energy dissipation device includes a mobile energy dissipation anchor block 201, a rotating roller 202 and a linkage chain 203 to achieve multi-level coordinated dispersion and dissipation of energy; the rotating roller 202 is arranged inside the protective grid 101, and its two ends are connected to the upper and lower ends of the protective grid 101, and the mobile energy dissipation anchor block 201 and the rotating roller 202 are connected by a linkage chain 203.

[0024] The rotating roller 202 provides necessary support and guidance for the smooth movement of the movable energy-absorbing anchor block 201 . The rotating roller 202 takes into account self-lubricating and wear-resistant properties to ensure smoothness and durability in long-term use.

[0025] The rotating rollers 202 and the movable energy-absorbing anchor blocks 201 correspond one to one, and several linkage chains 203 are connected between the corresponding rotating rollers 202 and the movable energy-absorbing anchor blocks 201. The redundant design of the linkage chains 203 ensures that the system can still operate stably when part of it is damaged. At the same time, the structure of the entire protective device is clear, which is easy to carry out daily maintenance and inspection work, thereby reducing long-term maintenance costs.

[0026] The movable energy-absorbing anchor block 201 is a heavy concrete block. When the protective device is impacted by a landslide, the movable energy-absorbing anchor block 201 converts the impact energy into its own kinetic energy and frictional work during movement, dissipating the energy. The linkage chain 203, a key component connecting the movable energy-absorbing anchor block 201 and the rotating roller 202, is made of a high-strength, high-toughness chain capable of withstanding significant tension and impact forces. Redundancy is incorporated into the linkage chain 203 to ensure stable operation of the entire system even if part of the chain is damaged.

[0027] Example 2

[0028] As another embodiment, this embodiment 2 proposes a more specific multi-stage coordinated mobile energy-consuming slope protection device based on the embodiment 1, such as Figure 2 As shown:

[0029] The buffer device 3 is installed at the downhill part of the protective grid 101, specifically, the buffer device 3 is installed between the protective grid 101 and the mobile energy-absorbing anchor block 201, and is used to control the moving speed of the energy-absorbing mobile anchor block to ensure a smooth and orderly energy-absorbing process and avoid secondary damage to the protective device.

[0030] The buffer device 3 includes a fixed column 301, a transmission shaft 302, and an electrical box 303. The bottom of the fixed column 301 is connected to the transmission shaft 302, and the bottom end of the transmission shaft 302 is connected to the output shaft of the electrical box 303. The electrical box 303 is used to control the rotation speed of the fixed column 301. The fixed column 301 rotates vertically. The middle of the linkage chain 203 is connected to the control chain 204, and the other end of the control chain 204 is wrapped around the fixed column 301. The installation position of the buffer device 3 is higher than the connection point between the control chain 204 and the linkage chain 203. This allows the control chain 204 to pull the linkage chain 203, gradually increasing the lever arm when the movable energy dissipation anchor block 201 begins to move. This helps to gradually disperse the impact energy of the landslide, thereby preventing the kinetic energy of the movable energy dissipation anchor block 201 from being dissipated and then re-acting on the protective device.

[0031] When a landslide occurs anywhere on the slope, the landslide body first impacts the protective device, which initially absorbs part of the impact energy through its elastic deformation and grid structure. Subsequently, the deformation of the protective net 102 triggers the response of the linkage chain 203, driving the mobile energy-absorbing anchor block 201 to move. During the movement process, the interaction between the mobile energy-absorbing anchor block 201, the fixed column 301, and the rotating roller 202 further dissipates the remaining impact energy, ultimately achieving multi-level coordinated energy dissipation. Throughout the entire process, the protective device, the energy-absorbing device, and the buffer device 3 work closely together to form an indestructible protective barrier.

[0032] It should be noted that the parts in this embodiment that are the same or similar to those in the first embodiment can be referenced to each other and will not be described in detail in this application.

[0033] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
