Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mine safety, especially a slope monitoring device for mine safety. BACKGROUND

[0002] In mining engineering, slope monitoring is a key link to ensure mine safety production. The stability of the slope is directly related to the production safety, economic benefits and personnel life safety of the mine. With the progress of science and technology and the expansion of mining scale, slope monitoring technology is also developing and improving. Traditional slope monitoring methods mainly rely on manual measurement and simple mechanical equipment. These methods not only consume time and effort, but also are difficult to realize real-time monitoring and early warning of the slope. In complex mine environment, the deformation and displacement of the slope often have suddenness and uncertainty, and the traditional monitoring method is difficult to capture these changes in time, thus bringing great hidden dangers to mine safety production.

[0003] The existing slope monitoring device for mine safety has limited monitoring range of a single sensor, and the range of the slope to be monitored is large, and the overall coverage cost is high.

[0004] A slope monitoring device disclosed in Chinese patent document with publication number A slope monitoring device includes a monitoring component, a positioning component and a sleeve, the positioning component is fixedly connected to one end of the monitoring component, the positioning component and the sleeve are connected in combination, the sleeve is embedded in the slope to be fixed, and a connecting rope is arranged between a plurality of slope monitoring devices. The above-mentioned application can monitor the slope slip and reinforce the slope at the same time, and reduce the property loss caused by disasters, but the slope monitoring device is fixed by the monitoring component, the cost is high, the installation efficiency is low, and it is not conducive to large-area laying.

[0005] In order to solve the above-mentioned problems existing in the prior art, a slope monitoring device for mine safety is provided, which is a problem worthy of study. CONTENT OF THE UTILITY MODEL

[0006] The utility model aims at overcoming the shortcomings that the existing slope monitoring device for mine safety has limited monitoring range of a single sensor, the range of the slope to be monitored is large, and the overall coverage cost is high, providing a slope monitoring device for mine safety, which realizes the technical effect of improving the coverage range of the monitoring device.

[0007] The utility model realizes the purpose through the following technical scheme:

[0009] The diameter of the monitoring anchor is matched with the inner diameter of the fixed ring, the slope protection net is fixed on the mine slope through the fixed ring and the monitoring anchor, and the entire slope is covered by anchors and connecting lines. This structure is more cost-effective and easier to install, greatly reducing the labor cost of installing the monitoring device.

[0010] The monitoring component includes a vibration sensor fixedly connected to one side of the bottom of the monitoring anchor, a tension sensor fixedly connected to one side of the top of the monitoring anchor, and a signal emitting device fixedly connected to the other side of the top of the monitoring anchor.

[0011] The vibration sensor and the tension sensor are electrically connected to the signal emitting device, which sends the received vibration sensor and tension sensor signals to the monitoring device control terminal. By monitoring and analyzing vibration data in real time, abnormal conditions of the slope can be detected in a timely manner, and appropriate measures can be taken to effectively prevent geological disasters.

[0012] The sensing end of the tension sensor is provided with a disc-shaped protrusion, and the four sides of the slope protection net are fixedly connected with a plurality of pull ropes. The ends of the pull ropes on the same side are connected together, and the converging ends of the pull ropes are wound around the protrusion of the sensing end of the tension sensor. The severity of slope changes can be determined by the tension detected by the tension sensor, so that timely responses can be made.

[0013] The top height of the tension sensor and the signal emitting device is lower than the top height of the monitoring anchor, and a groove is formed in the top of the monitoring anchor. The formation of the groove in the top of the monitoring anchor can improve the accuracy of hammering with a hammer and reduce the probability of the hammer deviating from the limited tension sensor and signal emitting device.

[0014] A plurality of contraction grooves are formed in the outer side of the middle part of the monitoring anchor, and a spring sheet is fixedly connected in each contraction groove. The bottom of the spring sheet is fixedly connected with the bottom of the contraction groove, the shape of the inwardly contracted spring sheet is matched with the shape of the contraction groove, and the material of the spring sheet is alloy spring steel.

[0015] The reinforcing component includes a reinforcing disc fixedly connected to the slope protection net and a plurality of reinforcing nails fixedly connected to the bottom of the reinforcing disc.

[0016] The reinforcement plate is located at the connection point of the slope protection net. When the slope moves locally, it can move the slope protection net together, thus facilitating the detection of landslides by the tension sensor.

[0017] Positive and beneficial effects:

[0018] 1. The mine safety slope monitoring device uses monitoring anchors installed on the slope protection net to fix the net to the slope, thereby reinforcing and protecting the mine slope and reducing the probability of landslides.

[0019] 2. The slope monitoring device for mine safety can capture minute deformations and displacements of the slope under vibration, providing important data support for early warning of geological disasters. By monitoring and analyzing vibration data in real time, abnormal conditions of the slope can be detected in a timely manner, and corresponding countermeasures can be taken to effectively prevent the occurrence of geological disasters.

[0020] 3. The slope monitoring device for mine safety can detect local landslides and other displacements when the mine slope is affected. The change in the position of the rope will generate tension on the sensing end of the tension sensor. The signal transmitting device will then transmit the tension detected by the tension sensor to the control terminal of the relevant operators, so that local landslides and other situations on the mine slope can be detected in a timely manner.

[0035] As shown in Figures 5 to 6 , the top height of the tension sensor 5 and the signal transmitting device 6 is lower than the top height of the monitoring anchor 3, and a groove 8 is formed in the top of the monitoring anchor 3, by limiting the height of the tension sensor 5 and the signal transmitting device 6 to be lower than the top of the monitoring anchor 3, it can avoid damaging the tension sensor 5 and the signal transmitting device 6 when the detection anchor 3 is hammered into the soil layer, and the groove formed in the top of the monitoring anchor 3 can improve the accuracy of hammering and reduce the probability of hammering the tension sensor 5 and the signal transmitting device 6.
