Stereoscopic garage ventilation extinguishing system

Abstract

The invention discloses a stereoscopic garage ventilation extinguishing system. The stereoscopic garage ventilation extinguishing system comprises a garage body. A plurality of parking layers are arranged in the garage body from top to bottom, an elevating channel is arranged in the center of the garage body, a car elevating device is mounted in the elevating channel, and each parking layer is evenly divided into a plurality of parking spaces through partition walls; a ventilation channel is arranged in the garage body, a plurality of ventilation ducts are connected successively to form the ventilation channel, the adjacent two ventilation ducts are connected by connecting parts, each ventilation duct is set one by one for each corresponding parking layer, each parking space is provided with an air exhaust outlet, and draught fans and ventilation hoods are arranged on the position of air outlets of the ventilation ducts; and a plurality of first high pressure water nozzles are mounted on the top portion of each parking space, a drainage groove is formed in the bottom of each parking space, and the second high pressure water nozzles are arranged uniformly in the drainage grooves. Thus, the air in the stereoscopic garage is discharged through the ventilation ducts, so that the air in the stereoscopic garage is circulated with the outside world and the air quality in the stereoscopic garage is improved. The high-pressure water nozzles are set, so that the fire extinguishment is conducted efficiently.

Description

technical field [0001] The invention relates to a three-dimensional garage, in particular to a ventilation and fire extinguishing system for a three-dimensional garage. Background technique [0002] The traditional underground three-dimensional parking garage only realizes the ventilation of the underground three-dimensional parking garage 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 garage, the traditional ventilation The method cannot meet the hygienic requirements; in addition, if a fire breaks out, the smoke in the garage is difficult to get rid of. When inspection and maintenance personnel enter the parking garage, they can only enter with the oxygen supply equipment on their backs, which not only increases the baggage, but also is inconvenient for inspection and maintenance. In addition, poor ventilation w...

Problems solved by technology

[0002] The traditional underground three-dimensional parking garage only realizes the ventilation of the underground three-dimensional parking garage 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 garage, the traditional ventilation The method cannot meet the hygienic requirements; in addition, if a fire occurs, the smoke in the garage is difficult to get rid of

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

[0003] Due to the characteristics of the combination of buildings and garages, underground three-dimensional garages and parking towers have great space restrictions for fire extinguishing

Due to the fully automatic sealing performance of the parking tower, it is difficult to carry out manual fire extinguishing in time, and the underground garage is also difficult to extinguish fire in time due to the height of the entrance and exit
