Electric lighting smoke discharging skylight

Abstract

The invention discloses an electric lighting smoke discharging skylight, comprising a base frame part, a lighting part, a sash body and a transmission part, wherein a polyurethane frame (2) is arranged between the base frame part and the sash body; the sash body (1) is made from an aluminum alloy section which is composed of an outer frame (6) and an inner frame (7); the inner frame (7) is provided with a seal groove; an omega-type low-temperature resistant ethylene-propylene-diene monomer (EPDM) sealing strip (8) sealed with the polyurethane frame is arranged in the seal groove; the lighting part uses a glass fiber reinforced polyester lighting board (9) the surface of which is covered with an anti-aging polymer synthetic resin film layer; and the transmission part comprises an electric mechanism and a gear rack (5). By using the above structure, the phenomena of moisture condensation and damp are avoided, so as to achieve the optimal insulation and energy conservation effects; and the lighting board resists corrosion and aging, thereby prolonging the service life.

Description

technical field [0001] The invention relates to a skylight for industrial workshops, in particular to an electric daylighting and smoke exhausting skylight. Background technique [0002] In the factory workshop, the smoke and hot gas generated by combustion focus on the top of the building space to form smoke, which accumulates thicker in a short period of time, and quickly spreads throughout the building space until it is completely filled. If the building is equipped with an automatic smoke and heat exhaust window control system, quickly open the upper windows of the building to discharge smoke, and open the lower windows to ventilate if necessary, so that the ever-increasing smoke, heat and hot gas will be eliminated at the initial stage of the fire. Exhaust, the opening of the lower ventilation window can keep the air pressure difference inside and outside the building within an appropriate range. At present, the sealing performance and thermal insulation performance of...

AI Technical Summary

Problems solved by technology

At present, the sealing performance and thermal insulation performance of skylight sash components are not satisfactory

Especially in the winter in Northeast China, the temperature difference between indoor and outdoor is very large, and the "skylight" is very easy to "return to dew" and "return to moisture", and some high-tech equipment in the factory building is not allowed to drop even a drop of water, so it cannot make users satisfy
