The invention discloses an arched electric lighting smoke-discharge skylight which comprises a base frame part, a lighting part, a sash body and a transmission part, wherein the transmission part comprises an electric push rod assembly (9) and a middle support arm assembly (10); the upper part of the electric push rod assembly (9) is connected with a transmission rod (14) in a transmission rod sleeve (13) through a fixed seat (11) and a transmission arm (12) which are arranged on the push rod; the lower part of the push rod assembly (9) is fixed to a push rod seat (16) through a fixed seat (15) which is fixed to the lower part of the push rod; and one end of the middle support arm assembly (10) is connected with the sash body, and the other end of the middle support arm assembly (10) is connected with the transmission rod sleeve (13). In the structure of the invention, the opening and the closing of multiple skylights can be realized by one electric push rod; and therefore, the invention is convenient to operate and can greatly reduce the construction cost and the maintenance cost.
Description
technical field [0001] The invention relates to a daylighting and smoke-exhausting skylight, in particular to a circular arch type 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. However, the electric opening and closing devic...
