Description

Technical Field

[0001] This utility model relates to the field of water prevention and early warning, specifically to a water prevention and early warning device for underground coal mines. Background Technology

[0002] Coal mines are areas where humans extract coal resources from coal-rich areas. During coal mining, accidents such as water inrush can occur. A Chinese patent (authorization announcement number CN222162723 U) discloses a coal mine underground water prevention and early warning device. This patented technology uses a handwheel to rotate a threaded rod, which in turn moves a horizontal plate upwards. The horizontal plate then moves a measuring box upwards, positioning the measuring box at a suitable height. When water seeps into the coal mine, it enters the inner cavity through the inlet trough, causing the water level to rise. The buoyancy of the water causes a float to move upwards along the inner cavity, causing a contact block to move upwards along one side of the contact strip. When one side of the contact block contacts the water level warning height of the contact strip, the alarm device will sound. However, due to the large amount of impurities in coal mine water, there is a problem of the seepage point being blocked by coal slag and other impurities. Therefore, those skilled in the art have provided a coal mine underground water prevention and early warning device to solve the problems mentioned in the background art. Utility Model Content
