Description

Technical Field

[0001] The invention relates to the technical field of subsidence monitoring, and in particular to a device for monitoring subsidence of overburden caused by coal seam mining. Background Art

[0002] The coal seam mining overburden settlement monitoring device is an important equipment for monitoring the overburden settlement during coal mining. When the existing surface settlement monitoring device is in use, solar energy is usually used as the output power to power the surface settlement monitoring device.

[0003] The irradiation angle of solar panels has a significant impact on the output power. When the sun's rays are incident vertically, the output power of the panel is the highest; as the angle deviates, the output power gradually decreases; under different irradiation angles, the temperature of the panel will also change. Too high a temperature will affect the output power and efficiency.

[0004] After searching, the application with patent number 202410862583.2 discloses a settlement monitoring device, which includes: a support seat; a detection device, which is arranged on the support seat and is used to detect the settlement of the ground surface; a photovoltaic module, which is fixedly arranged on the support seat, and the photovoltaic module is electrically connected to the detection device to power the detection device; a cleaning device, which includes a water tank and a brushing assembly, the water tank has a drain outlet, and the brushing assembly has a brush, the brush is in contact with the surface of the photovoltaic module, the drain outlet is arranged corresponding to the surface of the photovoltaic module, and the brush has a first extreme position and a second extreme position relatively set relative to the photovoltaic module; a driving device, which is arranged on the support seat, and the driving device is connected to the brush driving device, and is used to drive the brush to move between the first extreme position and the second extreme position.

[0005] Although the brush of the cleaning device of the settlement monitoring device fits with the photovoltaic module, and the driving device can drive the brush to move on the surface of the photovoltaic module, and the water stored in the water tank can flow to the surface of the photovoltaic module through the drain port to improve the cleaning effect of the brush, the settlement monitoring device is not convenient for adjusting the inclination angle of the solar panel, and the solar panel cannot move with the sun, resulting in low photoelectric conversion efficiency.

[0006] Therefore, we proposed a device for monitoring overburden subsidence caused by coal mining. Summary of the invention

[0007] In view of the shortcomings of the prior art, the present invention provides a coal mining overburden settlement monitoring device, which solves the problem that the prior device is not convenient for adjusting the inclination angle of the solar panel and the solar panel cannot move with the sun, resulting in low photoelectric conversion efficiency.

[0012] When the turntable rotates, the turntable can drive the supporting rollers to rotate together, and the supporting rollers can support the turntable to prevent the turntable from being subjected to greater pressure, which may cause the turntable rod to bend.

[0025] The present invention provides a device for monitoring overburden settlement caused by coal mining. It has the following beneficial effects:

[0026] 1. The coal seam mining overburden settlement monitoring device can drive the solar panel to rotate with the shaft as the axis through the expansion and contraction of the double-axis cylinder until the inclination angle of the solar panel is between 30° and 40°, so as to facilitate the adjustment of the inclination angle of the solar panel, so as to adapt to the areas with different light angles. The stepper motor drives the rotating rod and the rotating disk to rotate, and then drives the support rod and the mounting plate on the top surface to rotate, so as to drive the solar panel to rotate together, and adjust the direction of the solar panel, so as to achieve the purpose of making the solar panel move with the sun, so as to make the solar panel be exposed to direct sunlight for a longer time, which is beneficial to improve the photoelectric conversion efficiency of the solar panel, and solves the problem that the existing device is not convenient for adjusting the inclination angle of the solar panel, and the solar panel cannot move with the sun, resulting in low photoelectric conversion efficiency;

[0027] 2. The coal seam mining overburden settlement monitoring device can blow air into the hose through the blower, and then the wind in the hose enters the interior of the cleaning plate, and finally the wind in the cleaning plate is discharged through the air holes, so that the sand and dust attached to the top surface of the solar panel can be blown down by the wind, which can prevent the sand and dust from adhering to the surface of the solar panel, resulting in a decrease in the heat dissipation efficiency and photoelectric conversion efficiency of the solar panel, thereby ensuring the normal operation of the detection device;

[0028] 3. In the coal seam mining overburden settlement monitoring device, the heat inside the solar panel will be transferred to the inside of the heat sink fins, and then dissipated into the air through the heat sink fins. By blowing air to the bottom of the heat sink fins through the fan, the air circulation rate around the heat sink fins can be increased, so as to improve the heat dissipation efficiency of the heat sink fins, thereby avoiding the occurrence of excessive temperature of the solar panel, which is beneficial to the protection of photovoltaic components.
