Description

Technical Field

[0001] The invention relates to the technical field of arsenic sandstone weathering rate detection, in particular to a device and a method for in-situ long-term measurement of arsenic sandstone surface weathering, dissolution and erosion rate. Background Art

[0002] The surface weathering, dissolution and erosion rate of arsenic sandstone is affected by many factors, including water flow, slope, W-OH concentration, etc. The measurement methods of the surface weathering, dissolution and erosion rate of arsenic sandstone mainly include: scour test method, vernier caliper measurement method, and in-situ long-term measurement method; the in-situ long-term measurement method mainly uses a laser distance sensor to measure, record the vertical and horizontal position data of the laser distance sensor on the measurement frame and the distance data obtained by the laser distance sensor data acquisition instrument, and form a three-dimensional data set. The three-dimensional undulation of the rock surface is mapped out through relevant software, and the weathering, dissolution and erosion rates of the rock surface are calculated by comparing the measurement data of different periods. When conducting in-situ long-term measurement of the weathering rate of the arsenic sandstone surface, it is more troublesome to measure the surface of some raised arsenic sandstone. Since the upper end and the left and right ends of the raised arsenic sandstone are exposed to different amounts of sunlight, water flow and wind and sand, the results of measuring the weathering rate of the arsenic sandstone surface separately are not accurate. In addition, the laser distance sensor is easily contaminated by wind and sand if it is not moved for a long time, resulting in inaccurate measurement results. Birds are also likely to land on the measuring equipment, causing damage to the instrument. For this reason, we propose an in-situ long-term measurement device and method for the weathering, dissolution and erosion rate measurement of the arsenic sandstone surface. Summary of the invention

9. A method for detecting the weathering, dissolution and erosion rate of arsenic sandstone surface in situ and for a long time, applied to the device for in situ and for measuring the weathering, dissolution and erosion rate of arsenic sandstone surface in situ and for a long time as claimed in claim 8, characterized in that: include: Step 1: drive the insertion rod (2) into the inner side of the arsenic sandstone, then unfold the horizontal plate (4), make the pressure plate (11) clamp into the inner side of the clamping rod (10), fix the horizontal plate (4), then pull the arc rod (62) out from the inner side of the arc plate (61), align the arc plate (61) with the upper end of the raised arsenic sandstone, and use the first distance sensor (63) and the two sets of second distance sensors (64) to measure the front end, rear end and upper end of the raised arsenic sandstone respectively; Step 2: The wind blows the blades (666) to drive the connecting shaft (664) to rotate on the push rod (663), thereby driving the dial plate (665) to rotate. The dial plate (665) can be used to dial the paddle (6512) to make the support column (658) drive the extension shaft (652) to rotate on the fixed plate (651), thereby driving the rotating plate (653) to rotate, so that the extension plate (654) drives the cleaning cotton (655) to clean the second distance sensor (64); Step 3: The blade (666) continues to rotate, causing the slide post (6516) to abut against the apex of the arc track (6514). At this time, the paddle (665) will paddle the paddle (6512) to make the rotating housing (6510) rotate on the rotating post (659), so that the paddle (665) and the paddle (6512) are separated, making it easier for the first spring (657) to drive the extension shaft (652) to rotate; Step 4: When the rotating plate (653) rotates, the ball (6517) hits the convex point (6518) to make a sound, thereby driving away the birds.
