Tank Siltation Measuring Device

Abstract

The invention provides a safe and reliable water sump siltation measuring device which is low in investment and operating cost and capable of effectively reducing labor intensity of workers. The water sump siltation measuring device comprises a measuring ruler, a pull rope and a balance weight, and is characterized in that the measuring ruler is arranged on the top of a laneway where a laneway bottom plate is located. Pull rope lifting rings are arranged on the top of an inclined laneway of a water sump. A pulley is further arranged on the top of the water sump. One end of the pull rope is connected with a measuring sliding block, then passes the pull rope lifting rings and the pulley on the top of the inclined laneway of the water sump and finally is connected with the balance weight. The water sump siltation measuring device has the advantages of improving safety in the process of measuring siltation in the water sump, enabling workers to be capable of safely measuring the depth of the siltation in the water sump at a ventilating position, reducing damage of hazardous gas to human bodies, improving accuracy of the measuring value of the siltation in the water sump, enabling the workers to visually and accurately measure the depth of the siltation in the water sump through the siltation ruler and providing reliable parameters for four-protection work in rainy seasons.

Description

technical field [0001] The invention relates to a sedimentation measuring device of an underground water tank in a coal mine. Background technique [0002] The central pump room in the coal mine and the water tank of the pump room in the mining area are an important part of the mine drainage system. Its main function is to store mine water and reduce water flow velocity to ensure normal drainage needs. According to the relevant regulations, the silt situation of the main water tank should be checked regularly. To a certain extent, the silt should be cleared and excavated in time, especially in the rainy season, the water tank should be thoroughly cleaned to ensure the effective water storage volume and improve the mine's ability to resist disasters. Due to the particularity of the water tank roadway, there may be toxic and harmful gases in the mine water tank, which may cause bodily injury to the workers, so it is inconvenient to check the normal sedimentation situation in...
