Description

A tunnel ventilation fan

technical field

The utility model relates to the technical field of tunnel ventilation, in particular to a tunnel ventilation fan.

Background technique

Tunnels can be divided into three categories according to their locations: mountain tunnels that pass under mountains or hills to shorten distances and avoid large ramps; underwater tunnels that pass under rivers or seabeds to cross rivers or straits ; In order to meet the needs of railways passing through big cities, they are called urban tunnels that pass underground in cities. Among these three types of tunnels, mountain tunnels are the most built. The interior of longer tunnels can be approximately regarded as a closed space at one end, and road tunnels Due to the high flow of medium-sized vehicles, the exhaust gas cannot be released in time, which makes the tunnel contain a large amount of pollutants, harmful gases such as carbon monoxide and sulfur dioxide, which reduces the air quality. At the same time, there will be a large amount of moisture in the tunnel that cannot be discharged. In order to solve this The problem is that a ventilation fan is generally installed inside the tunnel. After the fan has been used for a long time, if a lot of dust accumulates in the fan, due to the long length of the tunnel fan, it becomes difficult to clean the fan. At the same time, the dust accumulates in the fan. The interior of the fan will also cause a certain degree of interference to the normal operation of the fan in the fan, so in order to avoid these situations, a dust-proof net is generally installed at the air inlet of the fan.

In order to prevent the dust-proof net at the air inlet from being clogged, traditional tunnel ventilation fans usually only use mechanical components to drive the scraper to scrape off the dust on the surface of the dust-proof net. However, in actual use, due to the heavy humidity in the tunnel, the Due to the high humidity on the dust surface, when the scraper scrapes off the dust on the surface of the dust-proof net, the dust has strong adhesion due to the high surface humidity, which makes the scraper unable to effectively scrape off the dust attached to the surface of the dust-proof net. Therefore, it is necessary to The tunnel ventilation fan is designed and modified to effectively prevent the phenomenon that it cannot quickly remove the dust on the surface of the dust-proof net at the inlet of the tunnel ventilation fan.
