Description

Technical Field

[0001] The utility model relates to the technical field of coal mine fans, in particular to a monitoring system for a coal mine fan that does not stop blowing. Background Art

[0002] Due to the high gas content in coal mines, gas outbursts are prone to occur during coal mining, so it is necessary to strictly carry out ventilation work in coal mines. Ventilation safety in mines is the top priority of coal mine safety production, and mine ventilators are responsible for mine ventilation tasks, and generally two groups are set up, one of which is used as a backup fan on standby at any time.

[0003] In the actual production process of coal mines, the main ventilation fans of the mines need to be overhauled and shut down due to faults. During this process, ventilation in the mine will be suspended for a period of time. In mines with high gas content, a brief suspension of ventilation will cause the gas content to exceed the standard, which poses a high safety hazard. Therefore, further improvements can be made. Utility Model Content

[0005] As an optimization, the wind speed sensor and controller signal are connected, and the alarm and controller signal are connected. The wind speed sensor can monitor the wind speed in the connecting pipe in real time. Once a fault occurs and the wind speed drops to a limit value, a signal will be transmitted to the controller, and then the controller will control the alarm to turn on and sound an alarm, thereby serving as a timely reminder for monitoring.

[0006] As an optimization, the damper assembly includes a support rod rotatably connected to the inner walls on both sides of the wind tube, the ends of the support rod are rotatably connected to rotating plates, door panels are clamped between the rotating plates, a connecting plate is provided on the inner side of the rotating plate, both ends and the middle part of the connecting plate are rotatably connected to rotating shafts, a part of the connecting plate close to the rotating shaft is rotatably connected to a rotating column, a fixing rod is fixedly installed inside the wind tube, the end of the fixing rod is rotatably connected to a support, and an electric push rod is fixedly installed on one side of the support.

[0007] As an optimization, a through hole is opened at a corner of the rotating plate close to the rotating shaft, the rotating shaft is rotatably inserted in the through hole, and the connecting plate is inserted into the through hole through the rotating shaft and is hinged to the three sets of rotating plates.

[0008] As an optimization, the three groups of rotating plates are linked to each other through connecting plates to form a shutter-like opening and closing structure.

[0009] As an optimization, a support plate is fixedly installed at the telescopic end of the electric push rod, and the support plate is rotatably connected to the end of the rotating column. By starting the electric push rod, the connecting plate will be pushed to move, which will drive the rotating plate to deflect upward with the support rod as the fulcrum, and then the damper will open.

[0010] As an optimization, the electric push rod is connected to the controller signal, and the wind speed is sensed by the wind speed sensor to transmit a signal to the controller, so that the electric push rod can be started in time by the controller in case of a fault, so that the air duct ventilation can be switched, and the machine can be reversed without stopping the fan.

[0011] The beneficial effects of the utility model are:

[0012] 1. The coal mine fan non-stop wind down monitoring system will push the connecting plate to offset through the electric push rod, which will drive the rotating plate to deflect upward with the support rod as the fulcrum, and then the horizontal damper will be opened, and the vertical damper will be closed at the same time, and then the faulty air duct will be closed. At the same time, the vertical damper on the other side will be opened, and it will be done at the same time, and then the air duct on the other side will be opened, so as to achieve the effect of non-stop wind down and reduce safety hazards.

[0013] 2. The coal mine fan non-stop wind down monitoring system can detect the wind speed in the air duct in real time through the wind speed sensor. If the fan fails, it will cause shutdown or wind speed reduction, which will be detected in time by the wind speed sensor, and then the signal will be transmitted to the controller, and the controller will control the alarm to start and sound the alarm, so as to timely remind the outside staff that the fan here has a fault. Thus, the role of real-time monitoring alarm is achieved. BRIEF DESCRIPTION OF THE DRAWINGS
