A vertical angle adjustment device for upper chute based on landslide physical model test

Abstract

The invention provides a vertical angle adjustment device for an upper chute based on a landslide physical model test, comprising a base, a lower trough body and a jacking mechanism, the base is fixed on the landslide, the lower trough body and the jacking mechanism are respectively arranged at both ends of the base, The adjustment device also includes a vertical angle adjustment section and an upper tank body. The vertical angle adjustment section is a fan-shaped tank structure and includes a plurality of fan-shaped sub-sections. The lowermost fan-shaped sub-section is connected to the inner side of the lower tank body, the uppermost fan-shaped sub-section of the vertical angle adjustment section is connected to the lower end of the upper tank body, and the upper end of the upper tank body is connected to the jacking mechanism, which lifts or descends to drive the upper tank body around The vertical angle adjustment section rotates, and the fan-shaped subsections of the vertical angle adjustment section are expanded or retracted, so that the upper chute in the upper tank and the lower chute in the lower tank form a predetermined angle. The beneficial effect of the present invention is that the large-scale continuous and flexible adjustment of the vertical angle of the upper chute is realized.

Description

technical field [0001] The invention relates to the field of landslide physical tests, in particular to an upper chute vertical angle adjustment device based on landslide physical model tests. Background technique [0002] The mechanism, influencing factors, movement characteristics and prediction of landslide disasters have always been hot issues studied by scholars at home and abroad. As a common geological disaster, landslides seriously threaten the safety of people's lives and properties. It is very important to carry out landslide physical model test research. The landslide physical model test can be carried out indoors, and it can better reflect the geological characteristics of the landslide disaster. The results obtained are relatively accurate, save time, and reduce the consumption of manpower and material resources. Therefore, indoor physical model tests have been extensively studied. personnel used in the study of landslides. [0003] Although the indoor landsli...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the large size of the existing landslide physical model test device, the relative vertical angle adjustment of the upper and lower sections is often time-consuming and labor-intensive;

[0005] (2) The existing landslide physical model test device can only realize the adjustment of the angle, but the adjustment range of the relative vertical angle of the upper and lower tanks and the hindrance that the adjusted device may cause to the movement of the sliding body have not been considered

[0006] (3) The material properties used in the existing vertical angle adjustment device of the upper chute have high requirements and are expensive, which is not conducive to the extensive development of landslide physical model tests
