Single-pin multi-point measuring and reading device of water and soil loss measuring pin and using method of single-pin multi-point measuring and reading device

Abstract

The invention discloses a single-pin multi-point measuring and reading device of a water and soil loss measuring pin. The single-pin multi-point measuring and reading device comprises a combined outer cylinder and a combined inner cylinder, wherein the combined outer cylinder comprises a central outer cylinder and at least two edge outer cylinders which are uniformly distributed around the central outer cylinder; the central outer cylinder and all the edge outer cylinders are parallel with each other and are fixed together by a top fixing plate, a middle fixing plate and a bottom fixing plate which are perpendicular to the central outer cylinder and all the edge outer cylinders; the bottom end of the central outer cylinder penetrates through the bottom fixing plate; the inner diameter of the central outer cylinder is greater than the outer diameter of a measuring pin cap; the inner cylinder is provided with a seal base and scales from top to bottom; an inner cylinder which is connected with the central outer cylinder and each outer edge outer cylinder in a sliding mode is inserted into the central outer cylinder and each outer edge outer cylinder. The invention also discloses a using method of the single-pin multi-point measuring and reading device of the water and soil loss measuring pin. The single-pin multi-point measuring and reading device and the using method thereof have the characteristics of convenience in outdoor operation, artificial factor prevention, accurate reading, simple structure, easiness in mastering, low use cost and reliable performances.

Description

technical field [0001] The invention belongs to the technical field of soil and water conservation monitoring facilities, in particular to a soil erosion measuring reading device and a method for using the same, which are applied to accurate reading and collection of measuring data in the measuring method for monitoring water and soil loss. Background technique [0002] As a global ecological problem, soil erosion has been paid more and more attention. How to effectively measure and control soil erosion has become the focus of widespread attention in all countries. In the construction of water and soil conservation and forestry ecological environment, the primary task is to monitor water and soil loss, provide quantitative monitoring data of water and soil loss for the regional ecosystem, predict the trend of regional water and soil loss, and then know a certain amount before and after the rainfall. The situation of soil erosion in the area can be controlled and protected in...

AI Technical Summary

Problems solved by technology

[0006] (1) Use a common measuring rod with a scale as the measuring rod. The measuring rod scale is easy to rust and peel off in the outdoor environment, resulting in data loss

[0007] (2) Due to the short scale of the exposed slope surface of the measured brazing, it is difficult for data collectors to read, and it is easy to increase the reading error due to the difficulty of viewing the line of sight

[0008] (3) The traditional measuring drill is usually hammered into the slope surface. Due to the certain flexibility of the measuring drill, it tends to become shorter under the action of hammering, resulting in smaller scale intervals on the measuring drill and inaccurate scales.

[0009] (4) It is necessary to measure the reading with the help of a ruler sticking to the ground. While the reading is difficult, it also increases the workload, resulting in low data collection efficiency

[0010] (5) The environment of the drill bit embedding site is complex, and it is easily affected by the random error of environmental factors such as the accumulation of weeds and gravel. The height of the buried soil at the drill bit embedment point changes, which increases the measurement and reading error and increases the error data.
