Description

Technical Field

[0001] The present application relates to the technical field of rock movement monitoring, and in particular to a rock movement monitoring and positioning device for a mine. Background Art

[0002] The phenomenon and process of rock strata movement and ground subsidence caused by underground mining is also called "rock strata and ground surface movement in mines". After the minerals are mined, the original mechanical equilibrium state of the rock mass around the mining area is destroyed, causing the rock strata to move, deform and be damaged. When the mining area reaches a certain range, the movement and damage will spread to the surface. Houses, buildings, railways, rivers, shafts and tunnels within the mining area will be deformed or damaged. The subject of mining subsidence is to observe and study the laws of these movements and deformations, as well as to prevent and control the harmful effects of these deformations and damages on people's production or life.

[0003] Among them, water disaster is one of the five major natural disasters in mining, and my country's coal mine production has long been threatened by water disasters. Groundwater monitoring and early warning technology is an important means to effectively prevent and control coal mine water disaster accidents. It comprehensively grasps the temporal and spatial evolution of groundwater through real-time monitoring of the water level, water temperature and water quality of the main underground aquifers in the mine, and promptly discovers abnormal changes in groundwater and then gives advance warning of mine water inrush disasters, thereby buying time and space for disaster prevention or escape of underground workers.

[0004] Traditional hydrological monitoring is to fix a central measuring tube into the monitoring well and install a hydrological sensor in the measuring tube to achieve monitoring. After installation, sand and gravel adhere to the inner wall of the measuring tube, causing bending when the hydrological sensor is installed. Therefore, traditional hydrological monitoring often faces the problem of being unable to quickly reach the specified position, affecting installation efficiency.

[0005] Therefore, it is necessary to provide a mine rock movement monitoring and positioning device to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Utility Model Content

[0009] A fixing frame is clamped at the bottom end of the mounting head, and the fixing frame is used to install the hydrological sensor head; a retaining ring is sleeved on the outer side of the mounting head, and the retaining ring is located on one side of the cleaning component; a through groove is circumferentially opened on the side wall of the mounting head, and a gear column is rotatably installed in the through groove, and the side of the gear column located inside the mounting head is meshed with the control cylinder, and the side of the gear column located outside the mounting head is meshed with the cleaning component; thus, one end of the hydrological sensor is installed in the middle of the fixing frame through the control rod, and the mounting head is placed in the monitoring pipe and suspended by the retaining ring; the control rod pushes the mounting head downward so that the hydrological sensor reaches the designated position; if there is a pile of sand and gravel blocking the pipe wall in the middle, the control rod moves upward to pull the control cylinder to rotate, and the cleaning component is controlled by the gear column to rotate to loosen the sand and gravel pile for removal.

[0010] Furthermore, a sliding key is circumferentially installed on the inner wall of the control cylinder, and teeth are arranged on the outer side of the control cylinder, and the teeth are meshed with the gear column; a spiral groove is circumferentially opened on the outer side of the control rod; the sliding key and the spiral groove are a matching structure; thus, the control rod controls the movement of the sliding key through the spiral groove, so that the control cylinder rotates, and then drives the gear column to rotate.

[0012] Furthermore, the fixing frame includes a middle component, a connecting arm, and a control component; one end of the connecting arm is fixed to the outside of the middle component, and the other end is clamped with the mounting head; the control component is concentrically arranged in the middle component and connected by a rubber ring; the side wall of the control component is located on one side of the rubber ring and is circumferentially provided with a plurality of movable cavities, and a dial is pivotally installed in the movable cavity, one end of the dial is located inside the control component, and the other end of the dial is located outside the control component and is hinged to the middle component; an opening one is opened on one side of the middle component, and an opening two is opened on one side of the control component, and the widths of the opening one and the opening two are consistent; thus, the control component is rotated so that the opening two and the opening one are aligned, and the head of the hydrological sensor is clamped into the control component, and then the control component is rotated to drive the dial to swing centripetally, so that the dial clamps the sensor end to achieve fixation.

The staff can intuitively know the internal pressure through the brightness of the positioning light. When the internal pressure is less than the rated range, the brightness of the positioning light decreases; when the internal pressure is greater than the rated range, the brightness of the positioning light increases, reminding the workers of the abnormality; thereby assisting the monitoring platform in monitoring, avoiding the situation where the hydrological sensor is damaged during use and causing the monitoring platform to fail to find the abnormality, so that the authenticity of the data is doubly guaranteed.

[0014] Furthermore, the monitoring and control component includes a floating plate, which is slidably installed in the reaction chamber; a plurality of wiring terminals are arranged on the side wall of the reaction chamber, and the wiring terminals are connected to the monitoring platform through a line;

[0015] There are contact terminals; therefore, when water overflows at the monitoring location, the floating plate moves upward in the reaction chamber to connect to the wiring terminals of the corresponding resistance circuit.
