Description

Background
With the improvement of the scientific and technical level, the development of the mining industry is also continuous and rapid, and the mining depth of coal mines is increasing day by day. However, roof separation is a main potential safety hazard of coal mine roof accidents, and roof strata need to be effectively monitored in order to timely master dynamic information of roof separation. The roof separation instrument is used for monitoring the movement of the roof rock stratum, so that roof collapse accidents can be effectively prevented, and the safety production of a coal mine is ensured.
In the related art, the monitoring of the top-bottom plate separation of the coal seam, the rock stratum or the soil layer can be implemented only under the condition of an optical fiber access, and the signal transmission cannot be carried out under the condition of optical fiber damage, so that the monitoring of geological and top-bottom plate separation data cannot be implemented. The reason for this is that the fiber grating sensor needs to constantly emit an optical signal and reflect the optical signal back through the grating for transmission during monitoring, however, monitoring data cannot be generated without a signal source being connected, and thus, the roof rock layer cannot be effectively monitored in real time.

According to the measurement apparatus 100 for fiber bragg grating delamination of the embodiment of the present invention, the first scale indicating portion is disposed at one end of the first measurement component 110, and the second scale indicating portion is disposed at one end of the second measurement component 120, so that the thickness of the delamination can be directly calculated by the scale value displayed by the first scale indicating portion and the scale value displayed by the second scale indicating portion, thereby implementing visualization of delamination data and facilitating visual observation of the thickness of the delamination.
According to an embodiment of the present invention, as shown with reference to fig. 1-9, the first measurement assembly 110 may include: a first anchoring grip 111, a first wire rope 112, a measuring cylinder 113, a first rotating member 114, a first winding ruler 115, a first rotating shaft 116 and a first spring 117.
The first anchoring claw 111 may be fixedly connected to the first measuring point, and one end of the first steel wire rope 112 may be fixedly connected to the first anchoring claw 111. Measuring cylinder 113 may be sleeved on first steel wire 112 to protect first steel wire 112 from being damaged by first steel wire 112. The other end of the first cable 112 may be fixedly connected to the first rotating member 114, and the first cable 112 is adapted to be wound around the first rotating member 114.
One end of the first measuring tape 115 can be connected with the first rotating member 114, the first measuring tape 115 is suitable for being wound on the first rotating member 114, the first measuring tape 115 is provided with a first scale indicating part, the length of the first measuring tape 115 wound on the first rotating member 114 is different, scale values shown by the first scale indicating part are different, and the scale values shown by the first scale indicating part can be directly observed.
The first rotating shaft 116 may be disposed on the first rotating member 114 in a penetrating manner, and the first rotating shaft 116 is fixedly connected to the first rotating member 114.
