Description

Technical Field

[0001] The utility model relates to the technical field of geological disaster early warning, in particular to a geological disaster early warning device. Background Art

[0002] Geological disasters refer to geological phenomena that are caused by natural geological actions or human activities and cause harm to human life, property and the environment. Landslides are a common type of geological disaster. It refers to the natural phenomenon that the soil or rocks on the slope lose balance under the action of gravity and slide down the slope as a whole or in a scattered manner along a certain weak surface or weak zone. In order to provide early warning and prevent landslide risks, landslide warning devices are generally installed on the mountain. The landslide warning device mainly monitors the tiny displacement changes of the slope by installing displacement sensors. The displacement sensors can monitor the horizontal displacement, vertical displacement and inclination angle parameters of the mountain in real time. When these parameters exceed the set threshold, it may indicate that the landslide activity is intensifying, thereby issuing a warning signal;

[0003] Existing landslide early warning devices are unable to provide timely warnings of falling rocks on mountains. Landslide early warning devices usually rely on monitoring the overall displacement changes of the slope and can only issue an alarm when the scale of the landslide is sufficient to trigger the preset threshold. They are unable to respond quickly in the initial development stage of a landslide and the response delay is long, increasing the difficulty and potential risks of emergency response when a landslide disaster occurs.

[0004] In order to solve the above problems, this application proposes a geological disaster early warning device. Utility Model Content

The bottoms of the two assembly columns are provided with net-type protective pieces, and the four sides of the net-type protective pieces are respectively connected to the corresponding elastic pullers;

[0008] A pressure warning component is installed on the side of the fixed cylinder. When the net-type protective component is subjected to force, it pulls the elastic pulling component to press the pressure warning component.

[0009] Preferably, the elastic puller includes a pull rod, a conical block and a first spring, a cavity is opened in the fixed cylinder, and an opening connected to the cavity is opened at the bottom end of the fixed cylinder, the pull rod slides through the opening and extends into the cavity, the conical block is slidably set in the cavity and connected to the end of the pull rod, the first spring is sleeved on the pull rod and located in the cavity, and the two ends of the first spring are respectively connected to the conical block and the bottom of the cavity, and the outer periphery of the conical block is formed with a conical inclined surface from top to bottom.

[0010] Preferably, the net-type protective member comprises a protective net, the protective net is arranged below the two assembly columns, and the protective net is connected with pull ropes around it, and the pull ropes around the protective net are respectively connected to the bottom ends of corresponding pull rods.

[0011] Preferably, the pressure warning component includes a pressure cylinder, which is installed on the side of the bottom end of the fixed cylinder, and a pressure channel is opened in the pressure cylinder.

[0014] The above technical solution of the utility model has the following beneficial technical effects:

[0015] By means of the elastic pullers, pressure warning parts and mesh protection parts, the two assembly columns can be installed obliquely on the slope of the mountain. When rocks fall in the early stage of a landslide, the rocks can be intercepted by the mesh protection parts on the two assembly columns.

[0021] like Figure 1-3 As shown, a geological disaster early warning device proposed by the utility model includes two assembly columns 1;

[0022] In this embodiment, both ends of the two assembly columns 1 are installed with fixed tubes 2, and elastic pullers 3 are installed in the fixed tubes 2, and the elastic pullers 3 extend out of the bottom end of the fixed tubes 2. The elastic pullers 3 include a pull rod 31, a conical block 32, and a first spring 33. A cavity is provided in the fixed tube 2, and an opening connected to the cavity is provided at the bottom end of the fixed tube 2. The pull rod 31 slides through the opening and extends into the cavity. The conical block 32 is slidably arranged in the cavity and connected to the end of the pull rod 31. The first spring 33 is sleeved on the pull rod 31 and is located in the cavity, and the two ends of the first spring 33 are respectively connected to the conical block 32 and the bottom of the cavity, and a conical inclined surface is formed on the outer periphery of the conical block 32 from top to bottom.

[0023] In this embodiment, a net-type protective member 5 is provided at the bottom of the two assembly columns 1, and the four sides of the net-type protective member 5 are respectively connected to the corresponding elastic pull members 3. The net-type protective member 5 includes a protective net 51, which is provided below the two assembly columns 1, and the four sides of the protective net 51 are connected to the pull ropes 52, and the pull ropes 52 around the protective net 51 are respectively connected to the bottom ends of the corresponding pull rods 31.

[0024] In this embodiment, a pressure warning member 4 is installed on the side of the fixed cylinder 2, and the mesh protective member 5 pulls the elastic pull member 3 to press the pressure warning member 4 after being stressed. The pressure warning member 4 includes a pressure cylinder 41, which is installed on the side of the bottom end of the fixed cylinder 2, and a pressure channel is opened in the pressure cylinder 41. A pressure sensor 42 is installed on the inner wall of the end of the pressure cylinder 41 away from the fixed cylinder 2, and an alarm 43 is installed on the end of the pressure cylinder 41 away from the fixed cylinder 2, and the pressure sensor 42 is electrically connected to the alarm 43. An elastic pressure-bearing part 44 that passes through one end of the pressure cylinder 41 and extends into the cavity is installed in the pressure channel. The elastic pressure-bearing part 44 includes a pressure block 441, a pressure rod 442 and a second spring 443. A through hole connected to the pressure channel is opened at one end of the pressure cylinder 41 close to the fixed cylinder 2. The pressure block 441 is slidably arranged in the pressure channel, and there is a distance between the pressure block 441 and the pressure sensor 42.

The pressure rod 442 pushes the pressure block 441 to approach the pressure sensor 42 and press it. After the pressure sensor 42 is subjected to pressure, the pressure signal can be transmitted to the alarm 43. The alarm 43 can be used to give a timely warning to remind pedestrians and vehicles to stay away from the mountain. This structure can give a timely warning response when rocks fall in the early stage of a landslide, and intercept the rocks, which can effectively protect the safety of pedestrians and vehicles and reduce the probability of accidents.
