Line drawing device for surface of deformation model of geological structure

Abstract

The invention discloses an apparatus used to scribe curves on the surface of the geologic structure deformation model, the test chamber is fixed on the operating console, the X direction traveler is mounted on the both sides of the operating console, and the sand hopper bracket is supported by the X direction traveler and could travel along it, the Y direction traveler is mounted on the sand hopper bracket, the leaking sand device is mounted on the Y direction traveler and could travel along it. The retaining bracket of leaking sand device is set on the Y direction traveler, the sliding rail is mounted on the retaining bracket by the mounting plate, the sand hopper is mounted on the rail via slide block and the vertical height could be adjusted by actuating device, and the open and close device is mounted in the inner of sand hopper. The up-down regulating device could take the sand hopper up and down via the up-down thong. The invention can prevent the model surface from damaging, draw canonical and pretty color grips simultaneously, and find the deforming location according to the displacement of sand after the deformation of test model. The invention improves the requirement for the accurate measurement of the finite strain and quantitative analysis. The apparatus is simple in structure and easy to use.

Description

1. Technical field [0001] The invention relates to an experimental equipment for drawing lines on the surface of a model in a geological structure simulation experiment, which uses a computer to control the "painting brush" to draw regular geometric figures on the surface of the model according to the intention of the experimenter, and is used to study the model The strain state of the surface before, during and after deformation. 2. Background technology [0002] Structural deformation simulation is an important experimental method for studying the deformation process of geological structures. Accurately measuring the deformation mode and deformation amount of the model surface is a key technology in the entire simulation experiment. Therefore, it is necessary to describe a certain regular geometry on the model surface. Pattern, divide the model into a series of units, observe and measure the changes of each unit before and after deformation. However, in the existing techn...

Problems solved by technology

The disadvantage of this method is that the surface structure of the model is destroyed before deformation, and it cannot truly reflect the force and deformation of the model surface. Moreover, during the deformation process of the model, the pattern is easily filled with the same material, and it is impossible to accurately find the pattern engraved after deformation. position, resulting in errors in quantitative analysis of finite strain
