Coal mine sump sludge thickness measuring device and measuring method

Abstract

The invention relates to the technical field of coal mine sump sludge thickness measurement, and discloses a coal mine sump sludge thickness measuring device and method.The measuring device comprises a supporting shaft and a height limiting disc on the outer side of the supporting shaft, a conical head is installed at the lower end of the supporting shaft, and a supporting outer ring is arranged in the height limiting disc; a rotating inner ring is installed in the supporting outer ring, a positioning pin is arranged on the inner wall of the rotating inner ring, a positioning sliding groove is formed in the outer side of the supporting shaft, the positioning pin is used for being connected into the positioning sliding groove in a sliding groove mode, and a contact shaft is installed in the supporting shaft. Through cooperation of the supporting shaft, the limiting sleeve and the height limiting disc, the rotating action during falling can be provided for the supporting shaft, the downward pressing resistance of the supporting shaft is greatly reduced, the function of measuring the thickness of sludge is achieved, and the mode is easy to operate, small in device size, convenient to carry and suitable for popularization and application. And the device also has a sludge height detection function in various water sump environments.

Description

technical field [0001] The invention relates to the technical field of silt thickness measurement in coal mine water silo, in particular to a coal mine silo silt thickness measurement device and a measurement method. Background technique [0002] When mining coal, there is a lot of underground water in coal mines. In order to facilitate the collection and storage of water, two or more water tanks are built. Clean up in time. According to the coal mine safety regulations, the silt in the water silo set in the main underground drainage pump room must be cleaned before the rainy season every year. During the daily management of the water silo, the thickness of the silt in the water silo cannot be observed, and this device is The sludge thickness measuring device used in coal mine sump. [0003] Chinese invention patent CN202110061152.2 discloses a coal mine water silo silt thickness measurement device. It includes a support base plate 1, a measuring belt 2 and a water inlet p...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a coal mine water tank silt thickness measuring device and measurement method, which has the beneficial effect of conveniently detecting the height of the silt in the tank, and solves the problem that the depth of the coal mine water tank mentioned in the background technology is not uniform. The conventional device can only It is difficult to detect the height of the silt in the silo, and the detection method is relatively simple. The existing devices usually use a shaft structure to press down and insert into the silt for detection, but this method has great limitations , when the shaft device is inserted into the sludge, the sludge is usually dense, which makes it difficult to insert the device into it, and affects the detection data. It is difficult to visually see the height of the sludge in the warehouse. At the same time, the device is large in size, cumbersome to operate, and not convenient enough to use , it is difficult to adapt to the problem of various measurement requirements
