Problems solved by technology

[0003] The traditional underground three-dimensional parking garage (such as figure 1 As shown) only through the opening and closing of the car-carrying turntable when parking and picking up the car, the ventilation of the underground three-dimensional parking garage is realized. Due to the oily smell released by the vehicle and the harmful gas accumulated at the bottom of the underground garage, the traditional ventilation method cannot meet hygiene requirements

Embodiment 1

[0029] Example one, please refer to Figure 2 to Figure 6 This embodiment discloses a mechanical ventilation device for an underground three-dimensional parking garage. A ground parking room is provided above the underground three-dimensional parking garage. The opposite side of the ground parking room is provided with a vehicle entrance 101 and a vehicle exit 102. The mechanical ventilation device of the parking garage includes: external exhaust shafts (ie, the external exhaust duct 701 on the left side of the underground three-dimensional garage and the external exhaust duct 701 on the right side of the underground three-dimensional garage) arranged on both sides of the underground three-dimensional parking garage and the ground parking house. 7) And the exhaust fans (ie, the left external exhaust fan 5 and the right external exhaust fan 6) respectively arranged in the corresponding external exhaust shaft, the bottom of the underground parking garage is provided with the two ...

Embodiment 2

[0039] Example two, please continue to refer Figure 2 to Figure 6 This embodiment discloses a natural ventilation method for an underground three-dimensional parking garage, which adopts the mechanical ventilation device of the underground three-dimensional parking garage as described in the first embodiment, and the middle part of the underground three-dimensional parking garage is provided with a vehicle for lifting and lowering the car turntable 3 Garage lifting channel 10, the upper and lower ends of the garage lifting channel 10 are respectively connected with the internal space of the ground parking house 1 and the air duct 9 at the bottom of the garage, and the car-carrying turntable 3 can divide the garage lifting channel 10 into two The surroundings of the underground three-dimensional parking garage are divided from top to bottom into a number of parking space structures 8, between the parking space structures 8 adjacent to each other, the lowest parking space structu...

Abstract

The invention discloses a mechanical ventilation device and method for an underground stereo garage. The device comprises externally-hung exhausting shafts arranged on the overall two sides of the underground stereo garage and a ground garage and exhaust fans arranged in the externally-hung exhausting shafts. A garage bottom air duct communicated with the externally-hung exhausting shafts on the two sides is arranged at the bottom of the underground stereo garage. The portions, opposite to the ground garage, of the externally-hung exhausting shafts are provided with ground air outlets. Under the effect of the exhaust fans, outdoor air flows through the ground garage into the underground stereo garage, and after reaching the garage bottom air duct, the air flows into the externally-hung exhausting shafts and is exhausted through the ground air outlets. By the adoption of the device and method, under the automobile taking and parking working condition or the automobile taking and parking waiting working condition, the peculiar smell in the underground stereo garage can be effectively diluted and exhausted rapidly, the influences caused by harmful gas in the underground stereo garage on persons going in and out of the underground stereo garage can be effectively reduced, and the environment temperature of equipment such as transformers in the underground stereo garage is remarkably reduced.

Description

Technical field [0001] The invention relates to underground garage ventilation, in particular to a mechanical ventilation device and a method for underground three-dimensional parking garages, and is particularly suitable for large-volume, deep-buried underground three-dimensional parking garages. Background technique [0002] With the development of society and economy, cars have gradually become popular in cities. According to statistics, there are more than 1 million cars in 31 cities across the country, of which more than 5 million cars in Beijing. Compared with scarce land resources in cities, parking spaces have become a hot favorite among car owners. For this reason, underground three-dimensional parking garages that can make full use of underground space have emerged. [0003] Traditional underground parking garage (such as figure 1 (Shown) only through the opening and closing of the car-carrying turntable when parking and picking up the car, the ventilation of the underg...
