Description

Technical Field

[0001] This utility model relates to the technical field of water accumulation detection devices, specifically a water accumulation detection device for the southern goaf area of ​​a mining field. Background Technology

[0002] Coal seams are layered solid combustible minerals formed from plant remains through complex biochemical and geological processes. They are found within coal-bearing rock formations, located between the roof and floor rocks. The number of coal seams, their thickness, occurrence, and burial depth are constrained by paleotectonic, paleogeographic, and paleoclimatic conditions. The occurrence of coal seams is a crucial basis for determining the economic value of coalfields and for development planning.

[0003] The existing Chinese utility model patent with announcement number CN219176403U discloses a tool for detecting water accumulation in the goaf of an overlying coal seam in a mining area. The tool includes an outer sleeve and a suspension rope. A U-shaped limiting plate is installed at the top of the outer sleeve. Trapezoidal support frames are installed on both sides of the top center of the U-shaped limiting plate. A support rod is installed at the upper end of each trapezoidal support frame. A strip-shaped support frame is installed on both sides of one end of the top of the U-shaped limiting plate. A rotating shaft is installed on the inner side of the middle of each strip-shaped support frame. Limiting rings are installed at both ends of the rotating shaft. This utility model, by incorporating an L-shaped rocker arm, can appropriately detect the depth of water accumulation in the goaf of an overlying coal seam in a mining area using the suspension rope. The rotation of the support rod and the rotating shaft avoids the need for manual handling of the suspension rope, which can easily cause physical exhaustion for workers during prolonged periods.

[0004] While the aforementioned tool for detecting water accumulation in the goaf of an overlying coal seam in a mining area solves the problem of existing water accumulation detection tools requiring manual hand-holding for stability by incorporating an L-shaped rocker arm, it still suffers from several drawbacks. As the sampling end descends, insufficient counterweight at the sampling end and the long distance between the sampling end and the target area make it difficult to maintain stable control, hindering stable water accumulation detection. Furthermore, the environment of the sampling area itself is a contributing factor to water accumulation, making it difficult to assess the environment during sampling, potentially leading to incomplete sample data. Additionally, impurities such as sand and slurry in the water can clog the ball valve, affecting the sampling efficiency and ultimately resulting in poor practicality of the equipment.
