Abstract

The invention discloses an underground ventilation protection structure comprising a front plate (2), a rear plate (3) and a top side plate (4) which surround to form a square cavity. A crossed partition (5) is arranged in the square cavity and divides the same to form a closed cavity (6), an expandable or retractable element (7) is mounted in the closed cavity (6), an input passage (8) is connected at an outlet of the expandable or retractable element (7) and extends out of the closed cavity (6) through an opening 11 on the front plate (2), and a valve (9) is mounted on the input passage (8).The underground ventilation protection structure ensures natural ventilation and stops snowstorm.

Description

technical field [0001] The invention relates to an underground ventilation protection structure. Background technique [0002] In underground buildings, it is often easy to have poor ventilation performance, or low ventilation efficiency, lack of natural ventilation, or even if there is natural ventilation, it deteriorates the permafrost in permafrost regions. Contents of the invention [0003] In view of the above shortcomings, the object of the present invention is to provide an underground ventilation protection structure, which ensures natural ventilation and prevents snowstorms. [0004] The technical solution of the present invention is: an underground ventilation protection structure, the underground ventilation protection structure comprises a front panel (2), a rear panel (3) and a top side panel (4), a front panel (2), a rear panel (3 ) and the top and side plates (4) form a square cavity, which is provided with a cross partition (5), and the cross partition (5)...
