Problems solved by technology

[0003] At present, the ventilation of highway tunnels is mostly fixed wind speed ventilation, and the fan is ventilated at a fixed speed, so there will be a problem of energy waste when the traffic flow is small, and good ventilation effect cannot be achieved when the traffic flow is large

Abstract

The invention relates to a device and method for achieving tunnel stepless ventilation through a wind power technology. The device comprises a wind power generation unit and a stepless ventilation speed regulation unit. The wind power generation unit is provided with a wind driven generator used for converting wind power at the windy position of a tunnel zone into electric energy and a storage battery connected with the wind driven generator; and the stepless ventilation speed regulation unit is connected with the storage battery and provided with a plurality of jet fans used for tunnel ventilation, a temperature and humidity sensor used for monitoring and transmitting air condition data in a tunnel in real time, an infrared vehicle detector, a CO sensor and a frequency conversion controller used for receiving the air condition data in the tunnel and controlling the air supply amount of the jet fans. Compared with the prior art, the air supply amount can be changed in real time according to the air condition in the tunnel, compared with traditional fixed wind speed, more energy can be saved, and the device can adapt to more complex environments in the tunnel.

Description

technical field [0001] The invention belongs to the technical field of tunnel ventilation, and in particular relates to a device and method for realizing stepless tunnel ventilation by using wind power technology. Background technique [0002] The construction of highway tunnels not only solves many factors such as long traffic journey, rough terrain, and inconvenient roads, but also effectively saves the precious time of travelers and plays a certain role in protecting the ecological environment. The harmful gas emitted by the car during the driving in the road tunnel will not only hinder the driving safety, but also greatly increase the harm to the body of the vehicle driver, and if the ventilation in the road tunnel is poor, the environment will be poor. Therefore, establishing a ventilation system inside the tunnel can exhaust the inside of the tunnel in a timely and effective manner, which can ensure that drivers have a good driving environment and driving safety in the...
