Three-dimensional laser scanner for surveying and mapping of mining subsidence area in coal mining area

Abstract

The invention discloses a three-dimensional laser scanner for surveying and mapping of a mining subsidence area in a coal mining area. The three-dimensional laser scanner is composed of first telescopic rods, a second telescopic rod, a mounting shell, a fourth fixed base and a scanning body. The second telescopic rod is installed at the bottom of the mounting shell by a third fixed base; second limiting holes are distributed in the second telescopic rod uniformly; a second support leg is installed at the bottom of the second telescopic rod by a second connector; and a mounting sleeve is installed at the second telescopic rod. According to the invention, on the basis of a series of structures including the first telescopic rods, the second telescopic rod, the mounting shell, the third fixing base and the scanning body, the telescopic rods uses the support legs to adjust the height of the scanner based on the environment and the scanning condition; LED light-supplementing lights carry out light supplementing on the scanner; a protection door is used for protecting a scanning lens of the scanner; and a bubble level is used for detecting the placing level of the scanner. The scanner having high practicability is worthy of promotion.

Description

technical field [0001] The invention relates to the field of scanners, in particular to a three-dimensional laser scanner for surveying and mapping mining subsidence areas in coal mining areas. Background technique [0002] China is a big consumer of coal resources. Coal resources account for about 70% of China's primary energy consumption. The mining of coal resources will inevitably cause land resources to be subsided, damaged, and occupied in varying degrees. The damaged land needs to pass through land Reclamation and other measures to restore it to its original state and productivity level. Among them, the damage characteristics, degree of damage and distribution of the land are the most important basis for choosing reclamation techniques and measures. Due to the different coal resources in various regions The conditions of occurrence are different, the mining techniques adopted in the mining process are also different, and the characteristics of land damage are also qui...

[0002] China is a big consumer of coal resources. Coal resources account for about 70% of China's primary energy consumption. The mining of coal resources will inevitably cause land resources to be subsided, damaged, and occupied in varying degrees. The damaged land needs to pass through land Reclamation and other measures to restore it to its original state and productivity level. Among them, the damage characteristics, degree of damage and distribution of the land are the most important basis for choosing reclamation techniques and measures. Due to the different coal resources in various regions The conditions of occurrence are different, the mining techniques adopted in the mining process are also different, and the characteristics of land damage are also quite different. In order to better grasp the mining area, it is necessary to use the corresponding 3D laser scanner to analyze the mining subsidence. However, the existing 3D laser scanners are relatively lacking, and their functions are relatively simple, and there are many deficiencies in scanning operations. Although the traditional 3D laser scanners have achieved the purpose of scanning operations, the overall balance is relatively poor. Poor, it is easy to cause the support surface of the scanner to tilt during operation, which will affect the scanning operation and reduce the practicability of the scanner. The use performance of the scanner is increased, and the limitations are increased. At the same time, the traditional 3D laser scanner has less protection for the scanning lens, which is easy to cause damage to the scanning lens during long-term external operations, and reduces the service life of the scanner.
