Description

Technical Field

[0001] The utility model relates to the technical field of alarms, in particular to a voice and light alarm for mining. Background Art

[0002] Coal mines are areas where humans extract coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, the coal is usually mined by tunneling underground, which is an underground coal mine. When the coal seam is very close to the surface, the coal is usually mined directly by removing the surface soil layer, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Underground coal mines generally include tunnels, shafts, and mining faces.

[0003] When working underground in a coal mine, real-time monitoring and management of parameters such as gas concentration, temperature, and humidity are required. When these parameters reach preset values, an audio and visual alarm sounds an alert, allowing miners to take timely measures to protect their safety. Existing lampshades are difficult to assemble and disassemble, typically using multiple bolts for fastening and requiring tools. This is time-consuming, labor-intensive, and inefficient. Furthermore, the underground working environment contains a high level of dust and impurities, which can infiltrate the lampshade, contaminating the alarm light and affecting its effectiveness.

[0022] When installing lampshade 2, connect lamp holder 4 to connecting groove 18, then drive moving block 5 to move, rotate rotating ring 3, rotate three arc plates 6 synchronously, arc plate 6 exerts a pushing force on L-shaped pressing plate 8, moves L-shaped pressing plate 8 forward, at this time, spring 14 is gradually elongated, until L-shaped pressing plate 8 is not movable, the end of L-shaped pressing plate 8 is pressed on lamp holder 4, improving the tightness of the connection between lamp holder 4 and connecting groove 18, effectively preventing the intrusion of foreign matter. At the same time, positioning column 17 is used to position moving block 5, prevent rotating ring 3 from rotating, and avoid lampshade 2 from loosening.

[0023] The positioning mechanism also includes a plurality of guide grooves 15 and a plurality of inclined surfaces 9. The guide grooves 15 are provided at the top of the housing 1 and are used to guide the L-shaped pressing plate 8. The inclined surfaces 9 are provided at the ends of the L-shaped pressing plate 8. When the lamp holder 4 is connected to the connecting grooves 18, the lamp holder 4 is slightly raised. During the forward movement of the L-shaped pressing plate 8, the inclined surfaces 9 slide relative to the outer edges of the lamp holder 4 until the bottom surface of the end of the L-shaped pressing plate 8 is connected to the top of the lamp holder 4. Figure 4 The middle a surface can realize pressing and fixing of the lamp holder 4.
