Intelligent environment-friendly tunnel ventilation system

Abstract

The invention relates to a tunnel ventilation system, in particular to an intelligent environment-friendly tunnel ventilation system. The intelligent environment-friendly tunnel ventilation system comprises a collecting box fixed in a tunnel and an air collecting box fixed to a slope of a tunnel entrance. An air inlet of the air collecting box communicates with the collecting box through an air inlet connecting pipe, and a temperature and humidity sensor, an air speed sensor, an air quantity sensor and an exhaust fan are arranged on the air inlet connecting pipe. An air outlet of the collecting box is connected with at least one fan power generating device through an air outlet connecting pipe. An integrated collecting main host is electrically connected with a video monitor, the temperature and humidity sensor, the air speed sensor and the air quantity sensor through wires. The video monitor is located on a supporting pipe, an electric heater is arranged in the air collecting box, andthe electric heater is electrically connected with a storage battery through a wire. According to the intelligent environment-friendly tunnel ventilation system, energy consumption is reduced, the ventilating performance is improved, warning is conducted in time, the failure point is advantageously found out, and the property loss caused by a tunnel fire accident is reduced.

Description

technical field [0001] The invention relates to a tunnel ventilation system, in particular to an intelligent and environment-friendly tunnel ventilation system that reduces energy consumption, improves ventilation performance, provides timely early warning, facilitates quick finding of fault points, and reduces property losses in tunnel fire accidents. Background technique [0002] With the development of my country's traffic engineering construction and traffic business, the mileage of traffic tunnels built in my country has been rapidly extended. Due to the increasing traffic flow, improvement of road conditions and the complexity of transported goods, the fire and tunnel pollution of traffic tunnels have increased. It has caused many serious catastrophic accidents, especially fire accidents, which not only seriously threaten human life and property safety, but also cause huge damage to transportation facilities and human production activities. The ventilation problem of tun...

Problems solved by technology

[0003] In the existing tunnel ventilation, high-power jet fans are generally installed equidistantly on the top wall of the tunnel to realize the ventilation of the tunnel. If the jet fans are turned on all the time, the power consumption is large. Once a fire occurs, the power supply cables of the high-power jet fans are easy to be burned. make the accident escalate

When a fire breaks out in an existing tunnel, there is no timely early warning. Subsequent vehicles will enter the tunnel one after another, causing congestion, further escalating the accident, and easily expanding the property loss of the accident.
