Safe and reliable tunnel ventilation device with vibration and detection functions

Abstract

The invention relates to a safe and reliable tunnel ventilation device with vibration and detection functions. The safe and reliable tunnel ventilation device comprises a mounting plate, a controller,a shell body, two connecting blocks and four mounting mechanisms, the shell body is internally provided with a motor, a rotating rod, a detecting rod, a detecting mechanism and a plurality of blades,each mounting mechanism includes a screw, a vertical rod, a convex shaft, a ring, a strip plate, a fixed plate, a vertical plate, a fixed shaft, a connecting shaft, a tension sensor and a first spring, the detection mechanism includes a disk and a plurality of detection assemblies. The safe and reliable tunnel ventilation device with the vibration and detection functions monitors vibration conditions of the mounting plate and the shell body through the mounting mechanisms, moreover, the vibration conditions of the rotating rod at the high speed are detected through the detection mechanism, and transmitted to a remote control device of management personnel through antennae, it is convenient for the management personnel to understand operation conditions of a fan, when vibration is violent,the fan is controlled to be stopped in time to avoid fan looseness due to excessive vibration, and safe operation of tunnel traffic is ensured.

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...

AI Technical Summary

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
