Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine detection devices, and in particular relates to a device for detecting the amount of coal sludge accumulation in an underground water bin of a coal mine. Background Art

[0002] Underground water silos are crucial components of underground drainage systems. They serve as centralized storage areas for mine water inrush, primarily collecting and storing it and settling the coal slime contained within. Because mine water contains large amounts of silt and impurities, which easily occupy the available water storage space, underground water silos often experience a gradual increase in coal slime deposition over time. This not only reduces water storage capacity but also compromises sedimentation efficiency, impacting drainage facilities and posing a significant risk to mine safety.

[0003] There has been no good dynamic detection method for the amount of coal slime accumulation in underground water silos. The current methods are mostly time assessment, which estimates the actual amount of coal slime accumulated in the silo based on the actual amount and time of coal slime water entering the silo. It cannot achieve real-time monitoring, let alone serve as an early warning. It is often not considered to clean the silo when the amount of coal slime accumulation in the silo is too large and a large amount of coal slime has entered the small water distribution wells of the main drainage system. At this time, the coal slime particles have caused a lot of wear and tear on the main drainage system and may even block the water suction port of the main drainage pump, endangering the safety of mine drainage. Therefore, when the amount of coal slime sedimentation in the silo reaches the design upper limit, it will seriously affect the use and drainage effect of the silo and it will be forced to stop use.

[0016] The present invention will be further described with reference to the accompanying drawings.

[0017] As shown in the figure, a device for detecting the amount of coal sludge accumulation in an underground water bin of a coal mine comprises a base 1, vertical rods 2 are provided at both ends of the base 1, a cross rod 3 is provided at the top of the vertical rod 2, a scale 4 is provided on the side surface of the cross rod 3, fixed pulley 1 5, fixed pulley 2 6 and fixed pulley 3 7 are provided at both ends and the bottom of the cross rod 3, a winch 8 is provided on one side of the vertical rod 2, a steel wire rope 9 is provided on the winch 8, one end of the steel wire rope 9 passes through the fixed pulley 1 5, fixed pulley 2 6 and fixed pulley 3 7 in sequence, and is then connected to a sinker 10.

[0018] Furthermore, the centers of the fixed pulley 1 5 and the fixed pulley 2 6 are located at the same level.

[0019] Furthermore, the fixed pulley 3 7 is located in the middle of the cross bar 3 .

[0020] Furthermore, the winch 8 is connected to the vertical pole 2 through a bracket.

[0021] Furthermore, a marking line is provided at a position where the steel wire rope 9 is aligned with the zero scale line of the scale 4 .

[0022] The utility model is suitable for detecting the amount of coal slime accumulation in the main water bin underground in coal mines. A sinker is hung on the front end of a steel wire rope and sunk to the bottom of the water. The sinker will stop falling when it encounters a coal slime accumulation layer. At this time, the length of the steel wire rope is read, combined with the height of the water bin, and the remainder of the two is the height of the coal slime accumulation. When the amount of coal slime accumulation is large, dredging work should be carried out.

[0023] The wire rope is marked at the 0m position on the scale (such as a red cloth strip or pointer, etc.) to indicate the length of the wire rope lowered.

[0024] When testing the amount of coal slime accumulation in a silo, place the device at the top of the silo, stabilize the sinker, check that the wire rope indicator is at zero, and slowly rotate the capstan. The wire rope passes through fixed pulleys 1, 2, and 3, moving vertically downward under the weight of the sinker. When the sinker encounters the coal slime accumulation layer, it is prevented from falling due to the surface tension of the coal slime. At this point, read the indicated length of the wire rope. The remainder of this length and the static height of the silo is the height of the coal slime accumulation in the silo.

[0025] This device has the characteristics of simple structure, accurate measurement and easy operation. It can accurately monitor the amount of coal sludge accumulation in the water absorption well, effectively prevent the water pump from being blocked due to excessive sludge accumulation, and effectively ensure the efficient operation of the drainage system with great social benefits.

[0026] There is almost no cost when using this device to detect the amount of coal slime accumulation every month; if a professional organization is invited to detect the amount of coal slime accumulation in the water tank, it will cost at least 10,000 yuan each time, and a total of 100,000 yuan a year.

[0027] This device can monitor the amount of coal sludge accumulated in underground water silos in coal mines in real time, ensuring that the silo capacity meets the requirements of the Coal Mine Safety Regulations. This ensures the safe use and drainage of underground water silos in mines, and has significant application value in the coal industry.
