Description

Technical Field

[0001] This utility model relates to the field of water inflow monitoring technology, specifically a mine water inflow monitoring device. Background Technology

[0002] In actual coal mining, mine water inflow is not only an important indicator for classifying the hydrogeological type of a coal mine and evaluating its mining technology, but also a primary basis for formulating water level lowering design schemes and determining the mine's production capacity. Accurate prediction of mine water inflow can greatly assist in coal seam mining and also play a role in protecting groundwater resources.

[0003] The existing Chinese utility model patent with publication number CN216976325U discloses a dynamic monitoring device for mine water inflow, including a base. A measuring box is fixedly connected to the top outer wall of the base, and installation handles are fixedly connected to both outer walls of the measuring box. A circular opening is formed on the top outer wall of the measuring box, and a protective tube is fixedly connected to the inner wall of the circular opening. An installation port is formed on one outer wall of the protective tube, and a drainage pump is fixedly connected to the inner wall of the installation port. A top plate is fixedly connected to the top outer wall of the protective tube, and a circular groove is formed on the top outer wall of the top plate. A turntable is connected to the bottom inner wall of the circular groove via a bearing. This utility model, by setting a measuring box on the outer wall of a water pressure sensor, facilitates the fixing of the water pressure sensor through the cooperation between the measuring box and the base. At the same time, by setting a screw and a reduction motor inside the measuring box, it is convenient to adjust the position of the water pressure sensor, thereby avoiding the problem of the water pressure sensor malfunctioning due to prolonged stay in one position.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it is known that mine water inflow systems are nonlinear, complex, and multi-parameter coupled dynamic systems. These systems not only evolve with the expansion of the mining area but also exhibit certain seasonal variations due to the influence of external climate conditions. Therefore, making accurate predictions and forecasts is often very difficult. These problems all affect the use of the equipment. Utility Model Content
