Problems solved by technology

These existing measurement institutions or methods have some shortcomings. (1) The measurement range of most institutions is limited, and there are not many institutions or methods capable of measuring large displacements.
When measuring large displacements, most mechanisms will be destroyed (such as optical fiber sensing) or the measurement error will be large
(2) Most of the mechanisms are not flexible, inconvenient to carry, and the flexibility in use is not high, limited by the environment
(3) Most institutions or methods obtain data discontinuously and easily interrupted

Embodiment 1

[0029] Please refer to Figure 1 to Figure 5 , the embodiment of the present invention provides a retractable mechanism for measuring large displacement of a landslide, including a chassis 1 and a telescopic mechanism 2 .

[0030] The chassis 1 is a sealed cuboid box structure, and its material can be painted steel plates. The sealed structure of the chassis 1 can ensure that the internal structure and components are not affected by the external environment. The bottom of the chassis 1 is fixedly connected with one or more first Outrigger 4, the bottom of the first outrigger 4 is fixedly connected to a square or circular flat plate, which is convenient for installation with pre-embedded piles and other mechanisms. The right side of the cabinet 1 is connected to the telescopic mechanism 2, and the telescopic mechanism 2 It includes a folding bracket 201 and a connecting rod 202 , the left end of the connecting rod 202 is hinged to the chassis 1 , and a slide rail is arranged on...

Embodiment 2

[0044] Please refer to Figure 6 , the second outrigger 5 is a telescopic outrigger, and the telescopic outrigger includes several telescopic rods 3 that are sequentially socketed. The telescopic rod 3 at the end is hinged with the right end of the first support 203 of the X-shaped support at the right end of the folding support 201. The range of height adjustment of the second outrigger 5 can be improved, and the height difference between the chassis 1 and the second outrigger 5 can be balanced, so that the measured displacement is closer to the horizontal displacement of the landslide.

[0045] Preferably in this embodiment, all telescopic rods 3 are connected by fixing bolts, and the top and bottom of the telescopic rods 3 are provided with screw holes cooperating with the fixing bolts, and the fixing bolts run through the screw holes at the top of the telescopic rods 3 below and The screw holes at the bottom of the telescopic rods 3 above are fixedly connected between the...

Abstract

The invention provides a mechanism capable of telescopically measuring landslide large displacement. The mechanism comprises a telescopic mechanism and a case; the telescopic mechanism comprises a folding support and a connecting rod, the folding support is arranged on the connecting rod in a sliding manner, the left end of the connecting rod is hinged to the case, a rope disc and a pull rope arearranged in the case, one end of the pull rope is fixed to the rope disc, the other end of the pull rope is connected to the right end of the folding support, the left end of the folding support is hinged to the case, a first supporting leg is arranged on the bottom of the case, and is fixed to a motionless body, the right end of the folding support is supported on a second supporting leg, the second supporting leg is fixed to a landslide, a circuit board and an encoder are arranged in the case, a control chip and a power module are arranged on the circuit board, the control chip is electrically connected with the encoder, when the landslide slides, the control chip calculates the displacement amount of the folding support according to the angle rotated by the rope disc, and according to the angle change amount of the connecting rod and the horizontal plane, the horizontal displacement of the landslide is calculated. The mechanism has the beneficial effects that the mechanism is free of space limiting, and the displacement of the landslide within the large range can be accurately measured.

Description

technical field [0001] The invention relates to the field of engineering geology, in particular to a retractable mechanism for measuring large displacements of landslides. Background technique [0002] A landslide refers to a certain part of the rock and soil on a mountain slope under the action of gravity, which is induced by external factors such as weathering, rainfall, water level, earthquake, blasting, excavation, and stacking, and produces significant shear along the weak surface (band). The action and phenomenon of moving down the slope as a whole due to displacement. Landslides are one of the common geological disasters in China, especially in mountainous areas, areas with heavy rainfall, reservoir areas, areas with frequent earthquakes, and areas with artificial activities. Landslides have become the main potential disasters. In reality, landslide prevention measures mainly include: (1) Establish geological disaster monitoring and early warning system engineering. ...
