Ventilation opening structure of underground garage

Abstract

The invention discloses a ventilation opening structure of an underground garage. The ventilation opening structure comprises a ventilation opening arranged on the ground, a shielding mechanism mounted above the ventilation opening and used for blocking impurities or rainwater to prevent sundries and rainwater from entering the ventilation opening, a fan rotationally mounted in the ventilation opening and used for increasing the air flowing speed in the ventilation opening and a drive device mounted above the shielding mechanism and used for driving rotating of the fan. The drive device comprises a vertically-arranged mounting disc and a drive disc. A mounting cavity is formed in the mounting disc, and a lighting opening is mounted on the side of the mounting disc. The drive disc is rotationally mounted in the mounting cavity, an annular drive cavity is formed on the drive disc, multiple air bags are arranged in the drive cavity and are in contact, gravity balls are arranged in the airbags, and the airbags are filled with evaporation liquid. In the ventilation opening structure, air flowing in the ventilation opening is accelerated through fan rotating, and therefore the ventilation effect in the underground garage is improved.

Description

technical field [0001] The invention belongs to the technical field of underground garages, in particular to an underground garage vent structure. Background technique [0002] With the development of urbanization and the improvement of people's living standards, the per capita ownership of cars is getting higher and higher. However, due to the non-renewable characteristics of land, especially the scarcity of urban land, it is difficult to build enough parking space. Bits are also getting more expensive. In order to solve the parking problem, most of the underground garages are used in residential areas or shopping malls, which can maximize the use of space and solve the problem of insufficient parking spaces. [0003] The ventilation problem is more important when the garage is set underground. The common method in the prior art is to open a vent on the ground to communicate with the underground garage. However, the existing vent has a simple structure and can only achieve...

AI Technical Summary

Problems solved by technology

[0003] The ventilation problem is more important when the garage is set underground. The common method in the prior art is to open a vent on the ground to communicate with the underground garage. However, the existing vent has a simple structure and can only achieve natural ventilation. The ventilation effect of low fluidity is average, which makes it difficult to maintain a dry air environment in the underground garage, which affects the use of users;

[0004] At the same time, in order to improve the fluidity of the air, other auxiliary equipment can also be used in the prior art to speed up the air flow, such as installing fans, air conditioners and other equipment to achieve air exchange with the outside; There are many additional power resources, the use cost is high, and the repair and maintenance cost is relatively high
