DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The technical solutions of the present invention will be further described in detail below through embodiments in conjunction with the drawings, but the present invention is not limited to the following embodiments.

[0028] The various exemplary embodiments, features, and aspects disclosed by the present invention will be described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0029] As Figure 1 - shown, the present invention provides the following embodiments: A geological disaster prevention and warning system for preventing and warning of dangerous rock collapse geological disasters on slopes provided with active protection nets, including a fixed frame, a linkage connection component, and a warning component. The fixed frame is fixed to the slope through anchor bolts. The linkage connection component is slidably arranged on the fixed frame. The linkage connection component is connected to the protection net and is used to drive the warning component to issue a warning signal.

[0030] Geological disasters pose a great threat to human life and property. In the prevention of dangerous rock collapse geological disasters, setting up an active protection net is a common means. For slopes with geological disaster risks, protection is set up, that is, there are hidden dangers of dangerous rock collapse geological disasters on slopes provided with protection nets. Here, the protection net generally refers to an active protection net, which covers and wraps the required slope with a steel wire rope net. The destructive characteristics of soil and rock will be directly reflected on the protection net. Monitoring the deformation characteristics of the protection net can accurately reflect the changes in the slope. By setting up a warning system, the deformation characteristics of the protection net are reflected through the warning group signal. Compared with the method of monitoring through GNSS technology, the cost of this system is greatly reduced, it can be well popularized, and its installation is simple and the construction difficulty is small.

[0031] The fixed frame serves as the basis of the warning system and is suitable for a rectangular frame structure. It is fixed to the slope through anchor bolts. The anchor bolts are arranged at the four corners of the rectangular frame and are connected by welding. For the fixing method of the anchor bolts, it needs to be determined in combination with construction experience according to different slope characteristics. Generally speaking, the warning system is set in the upper-middle part of the slope and installed along the trend of the slope. Here are several construction methods on the engineering site for illustration:

[0032] 1. For the case where there are outcrops, it is directly set on the outcrops; due to the uncertainty of the shape and size of the outcrops, when the size of the outcrop cannot completely cover the rectangular frame, it can be fixed by drilling on the nearby bedrock along the trend of the outcrop.

[0033] 2. If the bedrock burial depth is relatively shallow, the anchor bolts can be fixed to the bedrock by drilling.

[0034] 3. If the bedrock burial depth is relatively large, a concrete foundation can be set in combination with the fixing nodes of the protection net to fix the anchor bolts.

[0035] As a preferred solution, the linkage connection component includes a linkage mechanism and a connection mechanism. The linkage mechanism and the connection mechanism are connected to each other. On two opposite inner side walls of the fixed frame, there are first sliding grooves. On the outer side walls of the fixed frame corresponding to the two first sliding grooves, there are second sliding grooves. The linkage mechanism is slidably connected to the first sliding grooves, and the connection mechanism is slidably connected to the second sliding grooves. The connection mechanism is connected to the protective net and is connected to the linkage mechanism through a connection rope. The linkage mechanism drives the warning component.

[0036] The connection mechanism and the linkage mechanism are connected by a connection rope. When the protective net is deformed, the connection mechanism drives the linkage mechanism, and then drives the warning component. It should be noted that during installation, the connection rope between the connection mechanism and the linkage mechanism is not in a tensioned state. Instead, according to engineering experience, a section of ineffective stroke is set, aiming to filter out the deformation of the protective net caused by non-geological disasters, such as strong wind and other situations.

[0037] It should be noted that in order to ensure the strength of the fixed frame as much as possible, carbon steel was initially used in engineering practice and hot-dip galvanized treatment was carried out to prevent rust. The sliding grooves were formed by bending carbon steel plates. Although hot-dip galvanized treatment was carried out, when in the outdoor environment for a long time, there are sometimes weak points in the hot-dip galvanizing process. Once rust spots appear in the sliding grooves, resulting in rail jamming, it may affect the stability of the warning system. Therefore, another solution is given. The fixed frame still uses carbon steel and is hot-dip galvanized. Installation slots are reserved on the fixed frame. The two sliding grooves are made of acrylic material, that is, ASA material. After thermoplastic molding, they are snap-fitted into the installation slots and fixed. It has excellent mechanical properties, good coloring properties, excellent weather resistance, and good processability. At the same time, the supporting effect of the slot can also improve the strength of the ASA material sliding grooves. Accordingly, the components of the connection mechanism and the linkage mechanism are also replaced with ASA material, which can well solve the problem of poor weather resistance of metal materials outdoors.

[0038] The connection mechanism includes a connection cross bar and a transfer rod. Two transfer rods are respectively arranged at both ends of the connection cross bar. One end of the transfer rod is hinged to the connection cross bar, and the other end is rotatably connected to a roller. The roller is rollingly connected in the second sliding groove;

[0039] The connection cross bar is pulled by the deformation of the protective net, and the direction of the force is not determined. If the included angle between the direction of the force and the direction of the sliding groove reaches a certain degree, jamming may occur. In this case, since the force exerted on the connection cross bar by the protective net is very large, it may damage the relatively weak components on the warning system, resulting in the failure of the entire warning system. Therefore, the connection cross bar and the transfer rod are hinged to avoid jamming. Similarly, the connection between the transfer rod and the roller also has a corresponding rotation angle, further preventing jamming from occurring.

[0040] A first hook and a second hook are respectively arranged on the front and rear sides of the connecting cross bar. The first hook is connected to the protective net, and the second hook is connected to the linkage mechanism through a connecting rope.

[0041] As a preferred solution, the linkage mechanism includes a linkage cross bar and a driving rod. The two ends of the linkage cross bar are slidably connected in the first chute. The driving rod is fixedly connected to the linkage cross bar and is parallel to the first chute. A third hook is arranged on one side of the linkage cross bar close to the connecting cross bar. The third hook is connected to the second hook through a connecting rope.

[0042] A wedge-shaped trigger block is arranged on the driving rod for driving the warning component.

[0043] As a preferred solution, the warning component includes a jacking mechanism and a signal device. The jacking mechanism includes a tubular housing and a jacking rod arranged in the tubular housing. The tubular housing is connected to the fixed frame through a connecting plate. Third chutes are arranged on the opposite sides of the inner wall of the tubular housing. Sliders slidably connected in the third chutes are arranged on the jacking rod.

[0044] A wedge-shaped driving block is further arranged on the jacking rod. The inclined surface of the wedge-shaped trigger block abuts against the inclined surface of the wedge-shaped driving block.

[0045] The signal device is arranged on the top of the tubular housing. The signal device includes a switch and an alarm. The switch is arranged at the lower end of the signal device. The rising of the jacking rod triggers the switch, and the switch triggers the alarm.

[0046] The alarm is a sound and / or light alarm.

[0047] Specifically, the signal device further includes a power supply part for supplying power to the alarm. In this embodiment, the power supply part adopts a button battery. The alarm is in a standby state for a long time, so the power requirement for the battery is not high. The switch can adopt a micro switch or a travel switch and is triggered by the jacking rod.

[0048] The sound and light alarm can very intuitively make pedestrians, vehicles, etc. near the slope notice, playing a very good warning role. At the same time, it can also make the slope inspection very intuitive.

[0049] A stabilizing plate is further arranged at the bottom of the tubular housing. The driving rod is placed on the stabilizing plate. In terms of the spatial structure, the driving rod is located between the wedge-shaped driving block and the stabilizing plate. When the driving rod displaces and the wedge-shaped trigger block pushes the wedge-shaped driving block to move upward, the stabilizing plate is used to balance the force between the above two, so that the wedge-shaped driving block can stably rise.

[0050] As a preferred solution, a plurality of first hooks and second hooks are provided on the connecting cross bar, the third hook is arranged in the middle of the linkage cross bar, and a plurality of wire passing through holes are provided on one side of the fixed frame parallel to the connecting cross bar; the connecting ropes pass through the wire passing through holes and are respectively connected to the second hook and the third hook.

[0051] A plurality of first hooks are provided for selection when connecting the connecting cross bar and the protective net, so that the connecting ropes between the protective net and the connecting cross bar are as parallel as possible to the first chute. In this way, the force transmitted from the protective net can mainly act on the displacement of the entire linkage connection assembly, reducing the stress of the entire system and ensuring that the warning system is not damaged. The setting of the wire passing holes is to make the force transmitted from the connecting cross bar to the linkage cross bar only in the direction parallel to the second chute, avoiding jamming and damage of the linkage cross bar.

[0052] As a preferred solution, the geological disaster prevention and warning system includes two linkage connection assemblies, and the two linkage connection assemblies are symmetrically arranged on the fixed frame in a central symmetry manner. Two wedge-shaped driving blocks are arranged on the lifting rod and are respectively matched with two wedge-shaped trigger blocks. In this way, the deformation of the protective net can be monitored on both sides of the fixed frame, increasing the monitoring range of a single warning system.

[0053] As a preferred solution, connection blocks are respectively arranged on the connecting plate and the linkage cross bar, and the two connection blocks are connected by a threaded rod for adjusting the initial position of the linkage cross bar.

[0054] As a preferred solution, the signal device is connected to the tubular housing through a corrugated expansion joint. On the one hand, the upper end of the tubular housing is closed to prevent foreign objects from falling in and affecting the normal state of its internal components. On the other hand, it avoids the impact damage of the alarm caused by the rapid rise of the lifting rod. It should be noted that the self-weight of the alarm combined with the rising action of the lifting rod can complete the triggering of the switch.

[0055] As another implementation manner of the alarm, in combination with the signal transmitting device of the existing technology, the signal transmitting device is triggered by a switch to transmit a wireless signal, so that the alarm function of the alarm can be remotely transmitted to the monitoring station. This is the existing technology and will not be elaborated here. Of course, based on the alarm system provided by the present invention, any other feasible alarm can be used for warning.

The above description is exemplary and not exhaustive, and the scope of the present invention is not limited to the above-described embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the spirit and scope of the present invention.
