Description

Technical Field

[0001] The utility model relates to the technical field of coal mine engineering, in particular to an underground geophysical surveying device used in coal mining. Background Art

[0002] A coal mine refers to a place rich in coal resources underground or on the surface. It is mainly divided into two categories: underground coal mines and open-pit coal mines. Underground coal mines are suitable for situations where coal seams are buried deep underground. Coal is mined by digging underground tunnels, which requires complex engineering facilities and advanced technical support. Open-pit coal mines are suitable for areas where coal seams are close to the surface. Coal is mined by directly stripping the topsoil. Although the operation is direct, it faces challenges in land use and environmental protection. Coal, as an important solid fuel, can be divided into four categories according to its degree of coalification: peat, lignite, bituminous coal and anthracite. It is a key pillar of energy supply and industrial development.

[0003] However, there are many safety hazards in the coal mining process, such as gas explosions and mine collapses. These problems directly threaten the safety of miners and the production efficiency of coal mines. Therefore, coal mine safety management and technological innovation are particularly important. Safety management involves the strict design and implementation of mine ventilation, gas extraction, safety facilities, etc., aiming to reduce the risk of accidents and protect the safety of miners. At the same time, technological innovations such as the application of cable laying devices and intelligent monitoring systems provide new solutions and tools for coal mine safety production, effectively improving the efficiency and safety of mine operations. Therefore, the utility model provides an underground geophysical surveying equipment for coal mining. Utility Model Content

[0026] When the air flow in the well slows down, the rotation of the generator 303 slows down, and the support plate 401 is started at this time. The output end of the support plate 401 drives the sliding wheel 416 to move through the eccentric wheel 412, and the sliding wheel 416 drives the rotating rod 2 404 to move. The rotating rod 2 404 drives the rotating rod 1 403 and the rotating rod 3 405 to move. When the rotating rod 1 403 moves to the left, it contacts the touch member 402. At this time, the rotating rod 1 403 deforms the spring 414 through the spring connecting plate on the rotating rod 2 404. When the rotating rod 1 403 moves to the right, the spring connecting plate drives the connecting member 413 to move through the spring 414, and the connecting member 413 drives the sliding member 415 to slide in the sliding plate 411.

The sliding wheel 416 drives the rotating rod 2 404 to move, and the rotating rod 2 404 drives the rotating rod 1 403 and the rotating rod 3 405 to move. When the rotating rod 1 403 moves to the left, it contacts the touch piece 402. At this time, the rotating rod 1 403 is connected to the touch piece 402 through the spring on the rotating rod 2 404.
