Description

TECHNICAL FIELD

[0001] The utility model relates to geological exploration technical field especially relates to a mine area ground fissure measuring device. BACKGROUND

[0002] Geological exploration refers to the activity of investigating and researching geological information such as rock, mineral, geological structure and underground water on the earth surface and underground. The main purpose of geological exploration is to obtain geological information to provide scientific basis for mineral exploration, geological disaster prevention and land use planning. The measurement of ground fissure is very important. The existence of ground fissure can reflect the underground structure and geological activity, which is of great significance to the prevention of geological disasters and the evaluation of geological environment.

[0003] According to the ground fissure measuring device (authorization announcement number: CN 222258030 U) disclosed by the patent network, the utility model relates to geological exploration technical field, and specifically relates to a ground fissure measuring device. The utility model includes two interval arranged bases, the top surface of the base is fixedly installed with a stand, the bottom surface of the base is fixedly installed with a plurality of uniformly distributed fixed cones, the top end of the two stands is fixedly installed with a connecting plate, a measuring mechanism is arranged between the two stands, the measuring mechanism includes a mounting assembly, the two ends of the mounting assembly are slid on the two stands in a penetrating mode, and a height adjusting mechanism is arranged between the mounting assembly and the connecting plate; a width measuring assembly is slid in a damping mode in the mounting assembly, a depth measuring assembly is fixedly installed at the middle position of one side of the width measuring assembly; the initial distance between the two abutting plates is effectively reduced through the arrangement of the bidirectional screw rod and the mounting seat, compared with the prior art, the adaptability to the width size of the fissure is improved to a certain extent, and the use flexibility is good

[0004] For the above description, the applicant believes that the following problems exist: when the device is in use, the initial distance between the two abutment plates is effectively reduced through the cooperation of the bidirectional screw rod and the mounting seat, which significantly improves the adaptability of the device to different crack width sizes compared to the prior art, and enhances the flexibility during use. Specifically, the rotation of the bidirectional screw rod can drive the two abutment plates to move synchronously, so that they can be fine-tuned according to the actual width of the crack, thereby ensuring close fitting with the crack side wall during measurement. The device integrates the combination structure of the baffle and the laser range finder, which can obtain accurate distance data between the two abutment plates in real time. The laser range finder can instantly feedback the crack width information through non-contact measurement technology, realizing automatic collection and display of measurement data, effectively avoiding errors that may be caused by manual reading. However, the device still has certain limitations in actual detection process. Since the position of the abutment plate needs to be adjusted by manually rotating the bidirectional screw rod, the process is time-consuming, especially when the crack width is small, the screw rod needs to be adjusted repeatedly to realize accurate measurement, resulting in low overall measurement efficiency.
