Description

Technical Field

[0001] The utility model relates to the technical field of grouting, in particular to a cleaning device for an electronic density meter. Background Art

[0002] The North my country coalfields primarily mine Carboniferous-Permian coal seams. Mining is often threatened by flooding in the limestone aquifers beneath the floor, leading to frequent flooding incidents. Floor grouting has long been the primary engineering technology for pressurized coal mining. In the 1950s, with the development of indicators for assessing the water inrush coefficient and water hazard risk of coal seam floor aquifers, research on grouting technology targeting fault structures began in my country's major Carboniferous-Permian coal-producing regions.

[0003] With the development of grouting technology and process, many scholars have conducted special research on grouting materials, transformation processes, etc., and studied the migration laws of grouting slurry.

[0004] Coal mining enterprises have widely promoted and applied the use of directional drilling along the bedding for advanced regional management, and rapidly developed and applied it to the management of water-conducting structures such as floor faults and sinkholes, forming an advanced regional management technology that integrates advanced regional exploration and surface regional management.

[0005] The density of the slurry during the grouting process is particularly critical and plays a decisive role in the grouting effect. In order to improve the observation accuracy and save human resources, an electronic automatic observation density meter is often used to observe the slurry density. However, the density meter is a precision component and there are many factors that affect its accuracy. The most common one is that during the grouting process, the density meter works in the cement slurry for a long time, and the cement will adhere to the surface of the density meter, thereby affecting the observation accuracy. When the accuracy error occurs, the staff can only remove the density meter and flush the sensor, which is time-consuming and labor-intensive. The utility model is a device for flushing the density meter, which can flush the density meter without stopping the grouting work. Utility Model Content
