Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment: a safety warning device for coal mining tunnels, including a load-bearing plate 1 and an interception warning assembly; the upper end of the load-bearing plate 1 is equipped with an interception warning assembly for blocking passages and providing warnings. The interception warning assembly includes a positioning post 201, a telescopic rod 202, a connecting plate 204, a warning block 205, an interception plate 207, a lighting plate 209, an identification plate 210, and an infrared sensor 211. Two sets of load-bearing plates 1 are provided, and each set of load-bearing plates 1 has a positioning post 201 welded to its upper end. A telescopic rod 202 is installed inside the column 201. A connecting plate 204 is provided on the inner side of the telescopic rod 202. An alarm block 205 is fixed between the connecting plate 204 and the telescopic rod 202. A positioning plate 206 is welded to the lower end of the alarm block 205. Multiple sets of intercepting plates 207 are fixed inside the positioning plate 206. A fixing plate is welded to the end of the positioning plate 206 away from the alarm block 205. A drive module 203 is provided inside the lower end of the positioning column 201. A lead screw is provided at one end of the drive module 203 inside the positioning column 201.

[0022] Please see Figures 1-3 In this embodiment, multiple sets of warning lights 208 are fixedly installed on the outer end of the connecting plate 204, and a broadcasting sound is fixedly installed inside the warning block 205. The warning lights 208 and the broadcasting sound are used to warn workers to enter. The intensity of the warning lights 208 is controlled according to the intensity of the external ambient light, which enhances the warning effect in low light conditions at night and reminds others to pay attention to the safety of miners. The voice broadcast can warn workers from a distance to avoid going deep into the mine and ensure the safety of workers. One end of the load-bearing plate 1 is provided with a connecting rod 212, and one end of the connecting rod 212 is fixedly provided with a control module 214. The outer end of the connecting rod 212 is provided with two sets of screws. The connecting rod 212 is threadedly fixed to the load-bearing plate 1 by the screws. The warning lights 208 and the broadcasting sound are electrically connected to the control module 214. By using the control module 214 to control the operation of the warning lights 208 and the broadcasting sound, the possibility of human error is reduced and the risk of safety accidents caused by operational errors is lowered.

[0023] Please see Figures 2-3In this embodiment, the outer ends of both sets of positioning posts 201 are provided with multiple sets of lighting panels 209. The multiple sets of lighting panels 209 are fixedly connected to the positioning posts 201. By using multiple sets of lighting panels to assist lighting, more comprehensive lighting coverage is provided, enhancing visibility in the mine and reducing the risk of accidents caused by insufficient light. The outer walls of the two sets of positioning posts 201 are fixedly provided with identification plates 210. The lower end of the identification plates 210 is provided with multiple sets of infrared sensors 211. By using infrared sensors 211 to connect to the identification plates 210, the entry and exit records of personnel can be monitored during the closure period, and the entry of irrelevant personnel can be blocked, ensuring the safety of the mine during the closure period.

[0024] Please see Figures 2-4 In this embodiment, limit holes are provided at the upper corners of the two sets of load-bearing plates 1. When installing the device, bolts are inserted into the limit holes to help fix the load-bearing plates 1 to the ground, preventing them from shaking and improving the overall stability. One end of the identification plate 210 and the infrared sensor 211 is provided with a connecting cable. The identification plate 210 and the infrared sensor 211 are electrically connected to the control module 214 through the connecting cable.

[0025] During operation, the device is first moved to the interior of the mine and placed in front of a warning or no-entry zone. Multiple bolts are inserted into the limiting holes inside the load-bearing plate 1 to ensure a tight, threaded fixation to the ground and prevent shaking. After the load-bearing plate 1 is installed, the control module 214 is used to adjust the warning light 208, lighting panel 209, announcement system, identification panel 210, and infrared sensor 211, adjusting them according to the no-entry policy for the mine interior. The warning light 208 can control its intensity based on changes in ambient light, enhancing its warning effect in low-light conditions at night and alerting others to the miners' safety. The voice announcement can also warn workers from a distance, preventing them from venturing deeper into the mine. Furthermore, multiple lighting panels provide supplementary illumination to the mine, offering more comprehensive lighting coverage and enhancing the mine's safety. The visibility inside the mine is improved, reducing the risk of accidents caused by insufficient light. When it is necessary to seal the mine, the drive module 203 is activated, connecting the screw to drive the telescopic rod 202 to extend and adjust, driving the interception plate 207 to descend to the designated position to block the mine. When entry is prohibited, it effectively prevents workers from accidentally entering dangerous areas, reducing the risk of accidents and protecting worker safety. At the same time, when it is possible to enter the mine for work, the telescopic rod 202 extends and adjusts the interception plate 207 to open, providing a certain support effect for the top of the mine, reducing the risk of mine loosening and collapse caused by construction personnel entering or exiting or equipment impact. During the closure, when personnel need to enter for inspection, the infrared sensor 211 can connect to the identification plate 210 to identify personnel. During the closure, the system can monitor and record personnel entry and prevent unauthorized personnel from entering, ensuring safety during the mine closure.

[0026] Through the above steps, by using the telescopic rod 202 to drive the intercepting plate 207 to extend and retract to intercept the mine shaft, it effectively prevents workers from accidentally entering dangerous areas when entry is prohibited, reduces the risk of accidents, and protects the safety of workers. At the same time, when it is possible to enter the mine shaft for work, the telescopic rod 202 extends and retracts to adjust the opening of the intercepting plate 207, providing a certain support effect for the top of the mine shaft, reducing the risk of mine shaft loosening and collapse caused by construction personnel entering and exiting or equipment impact. Moreover, the telescopic rod 202 can be extended and retracted according to the specific size and shape of the mine shaft, adapting to the interception and support needs of different mine shafts, and improving overall practicality.
