Description

Technical Field

[0001] The utility model relates to the field of coal mines, in particular to an underground sound and light alarm amplification device for coal mines. Background Art

[0002] The sound and light alarm, also known as the sound and light alarm, is set up to meet the customer's special requirements for alarm loudness and installation location. It emits both sound and light alarm signals at the same time. Special fields: steel metallurgy, telecommunication towers, lifting machinery, construction machinery, ports and terminals, transportation, wind power generation, ocean-going ships and coal mining industries. It is an accessory product in the industrial alarm system, and the sound and light alarm device is needed at the monitoring site.

[0003] At present, in coal mining, sound and light alarm amplification devices are installed underground in coal mines to provide installation reminders. However, the patent application with publication number CN217739986U proposed in the prior art has an installation component movably installed on the rear end face of the box body, and can use the output end of the motor to drive the two-way screw to rotate. The rotation of the two-way screw drives the two groups of moving blocks to move in the direction of approaching or moving away from each other. The movement of the moving block drives the movement of the connecting block. The movement of the connecting block drives the movement of the transmission plate through the slider. The movement of the transmission plate drives the movement of the limit clamp. By adjusting the distance between the two groups of limit clamps, the effect of facilitating installation with vertical poles of different diameters is achieved. In addition, an anti-slip pad is provided on the inner wall of the limit clamp, which can increase the friction between the vertical pole and the vertical pole, which is beneficial to improving the stability after installation. This solves the problem that the traditional method is not convenient for installation with vertical poles of different diameters and cannot meet people's usage needs well.

[0004] However, when the device is installed underground in a coal mine, it is fixed with bolts: bolts and nuts suitable for the inner wall of the coal mine are selected to fix the equipment to the wall.

[0005] Anchor bracket: Install a special anchor bracket and install the monitoring equipment on the bracket.

[0006] Welding fixation: If conditions permit, the equipment can be fixed to the inner wall of the coal mine by welding.

[0007] Strong adhesive: Use special strong adhesive to stick the device to the wall.

[0008] Hanging device: Use the hanging device to hang the equipment on the inner wall of the coal mine

[0009] However, when the current sound and light alarm amplification device is installed, a clamp is installed on the back of the device to install the entire device. However, this method will increase the limitations of the device installation when fixing the sound and light alarm amplification device underground in a coal mine, and it is difficult to adapt to installation in various positions.

[0010] Therefore, it is necessary to provide a coal mine underground sound and light alarm amplification device to solve the above technical problems. Utility Model Content
