Electric daylighting and smoke exhaust louver

Abstract

The invention discloses an electric daylighting and smoke exhaust louver, which comprises a truss structure, a wind shield and a flashing are arranged around the truss structure, an upper layer of rain shields, a middle layer of rain shields and a lower layer of rain shields are evenly arranged on the truss structure, splash-proof nets which are located between the upper layer of rain shields and the lower layer of rain shields are arranged on the truss structure, and wind-shielding valve plates which are connected with one another through connecting rods are articulated with the truss structure; an electric driver which is connected with the wind-shielding valve plates is also arranged on the truss structure, and the wind-shielding valve plates can be automatically opened in a vertical state after the power of the electric driver is off. The electric daylighting and smoke exhaust louver has the advantages that: the electric daylighting and smoke exhaust louver has both a daylighting and ventilation function and a fire-fighting smoke exhaust function for buildings, and can meet the requirements of buildings on daily energy-saving ventilation regulation and fire-fighting emergency massive ventilation; by means of the wind-shielding valve plates, power-off automatic opening can be realized, the ventilation and smoke exhaust passage can be quickly opened within one second, consequently, the function of quick opening for smoke exhaust required by fire fighting can be ensured, and more time can be bought for the escape of people when a fire breaks out in a building.

Description

technical field [0001] The invention relates to a public building environment energy-saving technology and a building fire safety facility technology, in particular to an electric daylighting and smoke-exhausting skylight. Background technique [0002] For a long time, the natural lighting and ventilation design of public buildings has basically adopted the national standard "Electric Skylight for Lighting and Smoke Exhaust" (09J621-2). According to the current building energy-saving design "ventilation and fire-fighting and smoke-exhaust shared" functional requirements, daylighting and smoke-exhausting skylights, on the one hand, as building energy-saving environmental technology, have the daily lighting and ventilation functions of buildings; It can be opened quickly to ensure the fire and smoke exhaust function of the building, and can be closed immediately according to fire protection needs. But the existing daylighting and smoke exhaust skylight technology does not hav...

AI Technical Summary

Problems solved by technology

[0005] In terms of fire and smoke exhaust functions, the existing lighting and smoke exhaust skylights are not conducive to the emergency function requirements of fire and smoke exhaust: 1. The lighting and smoke exhaust skylights are closed for a long time, which cannot meet the daily building energy-saving ventilation and fire emergency smoke exhaust requirements

2. The daylighting and smoke exhaust skylight does not shelter from the wind, and the ventilation and smoke exhaust are greatly affected by the external wind force; the effective ventilation area of ​​the product is small, and the ventilation performance is low, technically unable to guarantee the massive and rapid smoke exhaust function required by fire protection

3. The daylighting and smoke exhaust skylight adopts a power window opening mechanism to overcome the gravity of the window sash by side rotation or horizontal translation, and the opening time is limited by the mechanical stroke

4. The power-off electric opening mechanism designed for fire emergency needs to be equipped with a backup pressure air source, the pneumatic-electric linkage mechanism is too complicated, and there are many uncertain factors in technical application

[0006] Through the above analysis, it can be seen that the existing daylighting and smoke exhaust skylight ventilation technology and fire emergency technology are seriously backward, but because there is no alternative technology, the design of public buildings has had to adopt the above backward technology for a long time, resulting in product design and consumption. Passive situation to the realization of product application functions

Public buildings cannot get the effect of natural ventilation and energy-saving applications, resulting in a large amount of energy-consuming ventilation waste, and the application of building fire-fighting and smoke exhaust is a great safety hazard
