Description

Technical Field

[0001] The invention relates to the technical field of coal mine safety protection equipment, in particular to a power failure alarm device for a backup power supply of a local fan in a coal mine. Background Art

[0002] In coal mine production, local fans are key equipment to ensure mine ventilation safety, especially in high-gas mines. The normal operation of local fans is directly related to the life safety of miners and the production efficiency of mines. However, due to the complex and changeable environment of coal mines and the instability of the power supply system, the backup power supply of local fans often fails. Once the backup power fails, if it is not discovered and measures are not taken in time, the local fans will stop working, which will cause serious safety hazards such as gas accumulation and over-limit, and may even cause coal mine safety accidents.

[0003] In order to deal with this problem, the coal mining industry has been committed to developing and improving the power failure alarm device for the backup power supply of local fans. These devices usually monitor the status of the backup power supply and immediately trigger an alarm signal when a power failure is detected, reminding relevant personnel to take timely countermeasures. In the case of loud noise and complex environment underground in coal mines, although most power failure alarm devices use sound and light alarms, which can alert nearby personnel to a certain extent, the alarm signal can be easily covered up or ignored; moreover, due to the vast space of the mine, the location of the alarm device is often fixed, resulting in miners far away from the alarm device area may not be able to receive the alarm signal in time. Summary of the invention

[0004] The purpose of the present invention is to provide a power failure alarm device for the backup power supply of local fans in coal mines. By having miners wear personal alarms, an alarm is issued to everyone when the backup power supply fails and the local fans cannot work, thereby solving the technical problem that miners far away from the alarm device area may not be able to receive the alarm signal in time.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:
