Description

Technical Field

[0001] The utility model relates to the technical field of geological prospecting equipment, in particular to a line-setting device for geological and geophysical prospecting. Background Art

[0002] Geophysical prospecting (abbreviated as geophysical prospecting) refers to the investigation of geological conditions, such as lithology and geological structure, through the study and observation of changes in various geophysical fields. Because the different rock media that make up the Earth's crust often differ in density, elasticity, electrical conductivity, magnetism, radioactivity, and thermal conductivity, these differences will cause corresponding localized changes in the geophysical fields. By measuring the distribution and variation of these physical fields and analyzing and studying them in combination with known geological data, geological properties can be inferred, thereby providing safe and reliable geological data for construction sites.

[0003] In the early stage of construction at a construction site, it is necessary to use geophysical equipment to detect the geology of the construction site of the construction site to ensure that the house is built on a qualified site and avoid the occurrence of safety accidents in the later stage. During geophysical exploration, lines will be laid out along the detection points. After the line is laid out, one end of the detection sensor will be inserted into the ground and the other end will be connected to the detection line. Through multiple detection sensors and detection lines, the geological conditions of the construction site will be detected, and the detection results will be displayed on the screen of the device host.

[0004] Chinese patent document CN217879682U discloses a pay-out device for geological and geophysical exploration, comprising two support plates, a rotating shaft, a take-up wheel, a clamping plate, a guide rod, a connecting plate, a clamping block, a first pulley, a second pulley, and a belt. This device avoids the need to hold the take-up wheel in hand during the pay-out process, thereby saving physical effort, and can automatically pay out the line while the take-up wheel moves, thereby improving the pay-out efficiency. However, in actual use, the user cannot know the length of the line that has been paid out during pay-out, which brings inconvenience to geophysical exploration work. Therefore, there is an urgent need for an improved pay-out device for geological and geophysical exploration to address this problem. Utility Model Content
