Description

[0002] Geological disasters refer to disastrous geological events formed by various geological actions during the development and evolution of the earth. They include many types, such as landslides and mudslides. Mudslides are a type of geological disaster that occurs in mountainous areas.

DETAILED DESCRIPTION

[0035] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In the related technology, there are many debris flow warning devices, such as impeller-type warning devices. The impeller-type warning device achieves the warning function by causing the debris flow to hit multiple impellers, causing the multiple impellers to deflect. However, due to the mountain environment, there are easy to be unexpected factors such as rolling stones, falling rocks or animals accidentally colliding with them. If a single impeller is stuck at a certain angle, it is easy to cause false alarms. At the same time, it is impossible to judge the scale of the debris flow by the deflection of the impeller, which is not conducive to the planning of subsequent risk avoidance measures.

[0038] In view of this, if Figure 1-Figure 3 As shown, some embodiments of the present invention provide a geological disaster warning device, including: a fixing mechanism, a flipping mechanism, a detection circuit and a variable resistance assembly; a plurality of flipping mechanisms are provided, each flipping mechanism is rotatably connected to the fixing mechanism, the fixing mechanism is inserted on the hillside, the variable resistance assembly is arranged on the flipping mechanism, and the detection circuit is respectively connected to the fixing mechanism, the flipping mechanism and the variable resistance assembly.

[0039] In the above embodiment, the fixing mechanism can be in a "U" shape, and the two parallel sides of the fixing mechanism can be fixedly connected to the hillside, the fixing mechanism can be inserted into the hillside, and one end of the flipping mechanism is sleeved on the side of the fixing mechanism parallel to the hillside, and multiple flipping mechanisms are evenly arranged along the length direction of the fixing mechanism, and each flipping mechanism is provided with a variable resistance component, and the detection circuit is extended along the surface of the fixed mechanism, and the detection circuit is connected to each variable resistance component respectively, so that when the flipping mechanism rotates and the variable resistance component is connected to the detection circuit, the detection circuit can judge whether the flipping mechanism is flipped and the magnitude of the flipping according to the change of current, thereby judging the scale of the mudslide. Furthermore, when multiple flipping mechanisms flip at the same time, current is generated in the circuit, and when a single flipping mechanism flips due to animals or falling rocks, no current is generated in the circuit, which will not cause false touch and false reporting of mudslide information, and the detection result will be more accurate.

[0040] Optionally, when each flipping mechanism does not flip, a variable resistance component arranged on one side of each flipping mechanism is not connected to the circuit, and the variable resistance component is connected to the circuit only when the flipping mechanism flips, so that it can be determined that a mudslide has occurred when each flipping mechanism flips. Furthermore, a resistance measuring mechanism can be separately provided on each variable resistance component to measure the resistance value of the variable resistance component connected to the circuit, and when each flipping mechanism does not flip, each variable resistance component is connected to the circuit with a maximum resistance value to minimize the current in the circuit, and when a single flipping mechanism flips, the resistance value of the single variable resistance component becomes smaller. Although the current in the circuit becomes larger at this time, combined with the resistance measuring mechanism, it can be determined that no mudslide has occurred at this time, thereby avoiding false reports of mudslide information. At the same time, the staff can be notified that the equipment is abnormal and needs to be dealt with in a timely manner.

Further, a connecting rod 3 can be arranged between the damping net 1 and the rotating column 2. The connecting rod 3 is cylindrical and is arranged perpendicular to the surface of the hillside.

The fixed axis 9 can be connected to the two anchor rods 8 respectively by welding, or it can be integrally formed and cast with the two anchor rods 8.

On the mounting blocks 10 on the left and right sides of the rotating column 2, each mounting block 10 is provided with a fixing hole on the end surface facing the rotating column 2 for fixing the elastic member 11, and the contact 12 is connected between the elastic ring and the rotating column 2, and the contact 12 is squeezed by the elastic member 11 to approach the rotating column 2, so that the arc surface of the contact 12 is squeezed on the end surface of the rotating column 2, and the contact 12 at one end corresponds to and is connected to the insulating sheet 4 and the resistor sheet 5, and the contact 12 at the other end is connected to the conductor ring 6, and when the damping net 1 is not in contact with the debris flow, the contacts 12 at both ends are separated. They are respectively connected to the insulating sheet 4 and the conductor ring 6, and the detection circuit can be connected to the elastic members 11 on both sides of the connecting column, so that the detection circuit is disconnected by the insulating sheet 4 and cannot generate current, thereby judging that no debris flow has occurred. When a debris flow occurs, the multiple damping nets 1 are all turned over. At this time, the multiple rotating columns 2 rotate, so that the contact 12 at the left end of each rotating column 2 can contact the resistor 5 after the insulating sheet 4 is removed, and the contact 12 on the right side is always connected to the conductor ring 6, so that the detection circuit is connected in sequence through the elastic member 11, the contact 12, the resistor 5, the connecting sheet 7, the conductor ring 6, another contact 12, and another elastic member 11, and is connected in the same way through the multiple rotating columns 2, so that the detection circuit is a closed path, thereby realizing the detection of debris flow.

[0056] Optionally, when a mudslide occurs, a current is generated in the circuit of the detection machine, and the size of the current can be used to determine the size of the resistance connected to the circuit. The larger the current, the smaller the resistance connected to the detection circuit. At this time, it is proved that the larger the rotation angle of each rotating column 2, the larger the scale of the mudslide. Therefore, the current in the detection circuit is proportional to the scale of the mudslide.

[0057] In an optional embodiment, the detection circuit includes a current sensor 14, a battery 13, a connecting wire and a wireless transmitter 15; the battery 13, the current sensor 14, and the wireless transmitter 15 are arranged in series via a connecting wire, and the connecting wire is arranged on a fixing mechanism and connected in series with the variable resistance component.

The protective shell can be connected to the anchor rods 8 on both sides, or the protective shell can be connected to the fixed axis 9. The protective shell is arranged to wrap around the circumference of the fixed axis 9. The protective shell can be wrapped around the rotating column 2 and the mounting block 10. A connecting line can also be arranged in the protective shell. At the same time, the protective shell has a through hole reserved for the connecting rod 3 at a position opposite to the damping net 1. When the debris flow impacts the damping net 1, the connecting rod 3 can drive the damping net 1 to rotate to avoid affecting the rotation of the rotating column 2.

[0060] Optionally, the detection circuit may also include a photovoltaic panel 16, a charging module and a controller. The photovoltaic panel 16 may be arranged at one end of the protective shell away from the hillside. The photovoltaic panel 16 is connected to the charging module.

The controller may be connected to the current sensor 14 and the wireless transmitter 15 for electrical signals. The controller may package the electrical signal of the current sensor 14 and transmit it via the wireless transmitter 15, so that the observer can know the specific current changes and the current value, thereby more accurately judging the scale of the debris flow.
