Description

TECHNICAL FIELD

[0001] The utility model belongs to coal mine prevention and control water monitoring technical field, concretely relates to a kind of coal mine prevention and control water monitoring sampling device. BACKGROUND

[0002] Coal mine prevention and control water monitoring sampling device is a kind of sampling equipment used in the process of coal mine geological prevention and control water monitoring, to obtain water sample from coal mine groundwater, so as to carry out subsequent water quality analysis and monitoring. The principle of the device is mainly based on the related theory of physics and geology, through specific sampling mechanism and power device, sampling cylinder is sent into predetermined groundwater layer, then water sample is extracted into sampling cylinder using sampling mechanism in sampling cylinder, finally water sample is taken out for analysis. Through coal mine prevention and control water monitoring sampling device, it can help coal mining enterprises to effectively monitor and control groundwater, prevent water disaster accidents. Through regular or irregular sampling analysis, the water quality condition, pollution degree and migration law of groundwater can be understood, so that corresponding prevention and control measures are taken to ensure the safety production of coal mine.

[0003] Chinese patent publication No. CN221123976U relates to the technical field of coal mine prevention and control water monitoring sampling device, and discloses a coal mine prevention and control water monitoring sampling device, which comprises a base, a universal wheel fixedly installed at the bottom of the base, a push frame fixedly installed at the top of the base, a limiting sleeve fixedly installed at the top of the base, a storage tank movably installed in the limiting sleeve, a counterweight one fixedly installed at the top of the base, an adjusting box fixedly installed at the top of the base, a sampling mechanism arranged in the adjusting box, and an adjusting mechanism arranged on the right side of the adjusting box. The third motor is arranged to make the extension rod move towards the sampling direction, thereby prolonging the sampling distance. After sampling is completed, the water sample is placed in the storage tank for storage, and then the next sampling is performed, so that the sampling is more convenient. The second motor is arranged to make the connecting shaft rotate, so that the stirring rod rotates, thereby avoiding the water grass at the bottom of the water from blocking the water inlet.
