Natural ventilation system of underground three-dimensional parking garage

Abstract

The invention discloses an underground stereo garage natural ventilation system. The underground stereo garage natural ventilation system is characterized in that a ground parking house is arranged above an underground stereo garage, a garage outer side ventilating duct and a garage bottom ventilating duct are respectively arranged on the outer side of the underground stereo garage and below the underground stereo garage, a ground parking house outer side ventilating duct communicated with the garage outer side ventilating duct is arranged on the outer side of the ground parking house, a top natural ventilation port is formed in the top of the ground parking house, a plurality of inner side natural ventilation openings and a plurality of outer side natural ventilation openings are respectively formed in an outer wall and an inner wall of the ground parking house outer side ventilating duct, and a plurality of underground parking space ventilation openings are respectively formed in an inner wall of the garage outer side ventilating duct from the top down. The underground stereo garage natural ventilation system can achieve through type overall natural ventilation and air change for the underground stereo garage whether under parking and car fetching work status or under non-work status, can effectively dilute and exclude peculiar smells in the underground stereo garage, significantly reduces environment temperature of devices of a transformer and the like in the underground stereo garage, and enhances smoke exclusion ability in a fire disaster.

Description

technical field [0001] The invention relates to the ventilation field of underground parking garages, in particular to a natural ventilation system for underground three-dimensional parking garages, and is especially suitable for underground three-dimensional parking garages with large buried depths and large parking numbers. Background technique [0002] With the development of society and economy, cars are gradually popularized in cities. According to statistics, there are 31 cities across the country with more than 1 million cars, including more than 5 million cars in Beijing. Compared with the scarce land resources in cities, parking spaces have become a hot favorite among car owners. Because of this, the underground three-dimensional parking garage that can make full use of the underground space came into being. [0003] The traditional underground three-dimensional parking garage, such as figure 1 As shown, the ventilation of the underground three-dimensional parkin...

AI Technical Summary

Problems solved by technology

[0003] The traditional underground three-dimensional parking garage, such as figure 1 As shown, the ventilation of the underground three-dimensional parking garage is realized only through the opening and closing of the car-carrying turntable when parking and picking up the car. Due to the oily smell released by the vehicle and the harmful gas accumulated at the bottom of the underground parking garage, the traditional ventilation method Failure to meet hygiene requirements

When inspection and maintenance personnel enter the parking garage, they can only carry the oxygen supply equipment on their backs, which not only increases the baggage, but also makes it inconvenient for inspection and maintenance

In addition, poor ventilation will lead to heat accumulation in the underground three-dimensional parking garage, which will reduce the efficiency of electrical equipment such as transformers and control cabinets. In the long run, it will affect the service life of equipment

In addition, the traditional underground three-dimensional parking garage does not consider the possibility of fire in the ground parking room, which also brings potential safety hazards
