Description

Technical Field

[0002] Landslide is one of the important geological disaster types that causes huge losses to people's production and life. As a geological phenomenon that is prevalent in nature, it is usually manifested as the deformation of natural or artificial slopes under the influence of the external environment, and the overall sliding when triggered by external environmental conditions. In order to avoid major losses to property safety caused by landslides, landslide warning is essential.

[0003] In the existing landslide early warning device, such as the Chinese patent application CN114973601A, when there is a hidden danger of landslide beside the mountain road, under the action of the slide bed drill rod on the slide bed, the buried drum frame is kept fixed in a limited position, the sliding body is displaced to squeeze the phase guide sleeve at the lower end of the buried drum frame, and under the action of the directional spring force, the multi-directional slide seat is displaced and slid on the multi-directional slide plate, and the first universal joint and the second universal joint close to the displacement and extrusion direction of the sliding body gradually approach each other. The jacking spring is compressed to lift the top plate on the second universal joint, thereby driving the warning device on the early warning support rod to rise. Passing drivers can timely predict the hidden danger of landslide ahead by the color height of the roadside warning device. It is suitable for early warning of hidden dangers of landslides on mountain roads and prevents the occurrence of landslide accidents on regional roads.

[0004] However, there are still the following problems: when the landslide warning device actually encounters a landslide after the warning is completed, the warning device will basically be buried by the landslide mudflow or directly destroyed by the impact force.

[0032] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, this application proposes a landslide early warning device and an early warning method for landslide disaster survey in mine rock and soil slopes.

A plurality of fixing claws 39 are fixedly mounted on the protective tube 31. The fixing claws 39 are circular and evenly distributed on the bottom end of the side wall of the protective tube 31. The fixing claws 39 are used to provide stability for the protective tube 31 after being fixed to the ground.

[0049] Furthermore, a slide rail 310 is fixedly installed on the top of the protection cylinder 31, and a second screw 311 is rotatably engaged on the slide rail 310.

[0051] Working principle:

[0052] The early warning device is placed at the installation position for installation, and the detection leaf 24 is used to detect the ground on the surface. When a landslide occurs, the detection leaf 24 detects that the ground on the surface is sliding, and the signal transmitter 26 is affected by the detection result of the detection leaf 24 and generates a signal. The signal transmitter 26 operates through the signal control auxiliary mechanism 3 to move the early warning mechanism 2 into the protection tube 31, and then the protection door 312 closes the protection tube 31.
