Problems solved by technology
[0003] However, this power supply method on the market has a disadvantage: the dedicated power supply line for the main fan and the dedicated power supply line for the backup fan are both disconnected, and the local fan will still be shut down at this time, and maintenance personnel lack emergency time to repair it. Maintenance, resulting in the rapid accumulation of gas gas in the excavation face, causing a gas explosion

The invention relates to the technical field of mining local fan power restoration, in particular to a mining local fan backup power source intelligent rapid power restoration device which comprises a main fan special power supply line, a backup fan special power supply line, a fan switch, a main fan fan and a backup fan fan, and the middle of the main fan special power supply line and the middle of the backup fan special power supply line are jointly provided with a power restoration device. The power recovery device comprises a shell, a U-shaped plate is fixedly connected to the top of an inner cavity of the shell, and a main fan work detection mechanism is arranged at the top of the U-shaped plate; the bottom of the main fan work detection mechanism is provided with a standby fan work detection mechanism which is started when the main fan special power supply line is powered off. By means of the power recovery device, when the power supply line special for the main fan or the power supply line special for the standby fan is disconnected, normal work of the standby fan can be guaranteed before the electric quantity of the battery is used up, gas explosion caused by rapid accumulation of gas on a driving working face is prevented, and meanwhile certain time is provided for maintenance of maintainers.
Description
technical field [0001] The invention relates to the technical field of power recovery of a mining local fan, in particular to an intelligent and fast power recovery device for a backup power supply of a mining local fan. Background technique [0002] In the field mining of coal mines, in order to prevent the accumulation of gas during mining, a local fan is usually installed on the head of the driving face to blow out the gas. In this way, the power supply of the local fan is particularly important. Once the local fan stops working due to the power supply, it will cause the rapid accumulation of gas in the excavation working surface, which will cause a gas explosion. This is the case. Coal mining enterprises generally use two-way power supply, that is, one main power supply and one backup power supply; if there is a problem with the main power supply line, the backup power supply will be put into operation quickly to avoid fan shutdown. [0003] However, this power supply m...
