A Safe and Reliable Tunnel Ventilation Device with Vibration Detection Function

Abstract

The invention relates to a safe and reliable tunnel ventilation device with a vibration detection function. The tunnel ventilation device comprises a top plate, a processor, a shell, two connecting blocks and four mounting mechanisms. A motor, a rotating shaft, a detection shaft, a detection mechanism and a plurality of fan blades are arranged in the shell; each mounting mechanism comprises a screw, a vertical rod, a first convex shaft, a lantern ring, a strip-shaped plate, a fixing plate, a vertical plate, a second convex shaft, a connecting rod, a tension meter and a first spring; and the detection mechanism comprises a detection disc and a plurality of detection assemblies. According to the safe and reliable tunnel ventilation device with the vibration detection function, the vibrationconditions of the top plate and the shell are monitored through the mounting mechanisms, moreover, the vibration condition of the rotating shaft during high-speed rotation is detected through the detection mechanism and is transmitted to a remote control device of a manager through an antenna, so that the manager knows the operation condition of a fan conveniently, the fan is controlled to stop intime when vibration is large, the fan is prevented from loosening due to excessive vibration, and safe operation of tunnel traffic is guaranteed.

Description

technical field [0001] The invention relates to the field of tunnel equipment, in particular to a safe and reliable tunnel ventilation device with a vibration detection function. Background technique [0002] Tunnel fans are also called tunnel jet fans and jet fans. They are widely used in tunnels such as roads, railways, and subways. Their main function is to ventilate the tunnels, remove harmful gases inside the tunnels, and ensure smooth air circulation in the tunnels. [0003] During the operation of the tunnel fan, the motor inside the casing drives the impeller to rotate at high speed. Due to factors such as the distribution of the center of gravity of the fan and installation problems, the motor is prone to vibration inside the casing during the high-speed rotation of the impeller. At the same time, the casing of the fan is in the tunnel. The top of the tunnel is also prone to vibration. When the vibration amplitude is large, the fan is easy to fall from the top of th...

Problems solved by technology

[0003] During the operation of the tunnel fan, the motor inside the casing drives the impeller to rotate at high speed. Due to factors such as the distribution of the center of gravity of the fan and installation problems, the motor is prone to vibration inside the casing during the high-speed rotation of the impeller. At the same time, the casing of the fan is in the tunnel. The top of the tunnel is also prone to vibration. When the vibration amplitude is large, the fan is easy to fall from the top of the tunnel, which brings various safety hazards to the passage of the tunnel. Because the existing tunnel fan cannot detect the vibration status of its own operation, resulting in Reduced availability of existing tunnel fans
