Description

Technical Field

[0001] This utility model relates to the technical field of surface subsidence detection tools, and in particular to a surface subsidence detection device for coal mining. Background Technology

[0002] Surface subsidence in coal mine goaf areas severely damages the mining environment. Monitoring and controlling surface subsidence in goaf areas has become an important measure for environmental governance in mining areas. Real-time monitoring of surface subsidence patterns is an important means of controlling surface subsidence and environmental assessment in goaf areas. Monitoring surface subsidence in mines is also an important measure to ensure the safety of surface derricks, winch rooms, and other buildings and structures. However, surface subsidence in mines is constantly under dynamic excavation disturbance. How to conduct long-term, effective, and accurate surface monitoring is a problem that mining enterprises urgently need to solve.

[0003] Currently, traditional methods for detecting land subsidence have many drawbacks. For example, total station measurements rely on manual operation, and data observation becomes complicated at night due to lighting conditions. Sensor-based monitoring methods, such as those using strain gauges and displacement sensors, are complex to install and maintain, and can only detect subsidence through data, lacking alarm devices to provide collapse warnings for areas experiencing rapid subsidence. Therefore, these problems need to be addressed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coal mine surface subsidence detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a coal mine surface subsidence detection device, comprising a base, an installation ring being bolted to the top surface of the base, a monitoring mechanism being installed on the installation ring, two limiting blocks being installed inside the installation ring, a detection rod being sleeved inside the installation ring, and an alarm mechanism being installed inside the detection rod.

[0006] Preferably, an mounting rod is installed on one side of the upper end of the detection rod, a solar panel is obliquely installed on the mounting rod, and sliding grooves are opened at the lower ends of both sides of the detection rod, and the limiting block is slidably connected in the sliding groove.

[0007] Preferably, the monitoring mechanism includes an observation ring sleeved on the middle of the detection rod, and four connecting rods are installed on the circumference of the bottom surface of the observation ring, with the lower ends of the connecting rods installed on the top surface of the mounting ring.

[0008] Preferably, a mounting groove is provided in the middle of the front end face of the detection rod, and a fluorescent lamp is provided at the front end of the mounting groove and the rear end of the transparent scale plate, and the fluorescent lamp is placed in the mounting groove.

[0009] Preferably, the alarm mechanism includes an alarm light mounted on the top of the detection rod, with a wire connected to the bottom of the alarm light, the wire extending towards the lower end of the detection rod.

[0010] Preferably, an insulating layer is installed at the bottom horizontal position of the conductor, and conductive sliders are inserted into both sides of the insulating layer. The two sliders are respectively connected to the positive and negative terminals of the solar panel, and a trapezoidal inclined surface is opened at the lower end of the two sliders.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the combination of a transparent scale plate and a fluorescent lamp, facilitates the penetration of fluorescence through the scale plate, thus enabling the observation of monitoring data even at night; furthermore, through the combination of a slider and a wire, when the detection rod descends to a dangerous position, the limiting block pushes the slider inward to connect with the wire, thereby energizing the wire and activating the alarm device, which helps to remind staff and reduce the accident rate; ultimately, it solves the problems of insufficient light and lack of alarm devices in commonly used inspection devices for nighttime monitoring data.

The device includes an alarm mechanism. A mounting rod 4 is installed on one side of the upper end of the detection rod 3, which facilitates the installation of a solar panel 5. The solar panel 5 is installed obliquely on the mounting rod 4, which facilitates the storage of electricity. The detection rod 3 has grooves on both sides at its lower end, and the limiting block 12 is slidably connected in the grooves. The monitoring mechanism includes an observation ring 6 sleeved in the middle of the detection rod 3, which facilitates the use of a transparent scale plate 7. Four connecting rods are installed on the bottom periphery of the observation ring 6, and the lower ends of the connecting rods are installed on the top surface of the mounting ring 2.

[0020] In this invention, a mounting groove is provided in the middle of the front end face of the detection rod 3, and a transparent scale plate 7 is installed at the front end of the mounting groove. The transparent scale plate 7 facilitates the observation of the descent height in conjunction with the observation ring 6. A cavity is provided at the rear end of the transparent scale plate 7, and a fluorescent lamp 8 is installed in the cavity. The fluorescent lamp 8 provides light for nighttime monitoring. The alarm mechanism includes an alarm light 9 installed at the top of the detection rod 3. The alarm light 9 helps to alert staff to safety accidents. A wire 10 is connected to the bottom end of the alarm light 9, which provides power to the alarm light 9. The wire 10 extends to the lower end of the detection rod 3, and an insulating layer is installed at the horizontal position of the bottom end of the wire 10. A conductive slider 11 is inserted on both sides of the insulating layer, which facilitates the conduction of electricity to the wire 10.

[0021] Working principle: When using this utility model, firstly, the mounting ring 2 is installed on the base 1 using fixing bolts.

The detection rod 3 is inserted into the inside of the mounting ring 2, and the bottom end of the detection rod 3 is inserted into the designated underground position. At this time, the solar panel 5 is installed on the upper end of the detection rod 3 through the mounting rod 4. The power of the fluorescent lamp 8 is turned on. At this time, the position of the observation ring 6 on the transparent scale plate 7 is observed and recorded. Afterwards, the data is recorded at regular intervals to calculate the sinking height. When the detection rod 3 sinks to the danger zone, the limiting block 12 pushes the slider 11 to slide inward and abut against the wire 10. At this time, the wire 10 is energized, and the alarm light 9 lights up to remind the staff to avoid excessive sinking and causing a collapse.
