Roof thin lighting ventilator

Abstract

The invention discloses a thin roof daylighting ventilator, which comprises a plurality of longitudinal rods and a plurality of rows of structure trusses, wherein outer guard boards are arranged around the rows of structure trusses. The thin roof daylighting ventilator is characterized in that each row of structure trusses are composed of one or more truss units, and each truss unit comprises a plurality of ventilation units; a rain baffle plate is connected between each line of ventilation units, and a shelter valve board is symmetrically hinged on each line of ventilation units; an air outlet is formed between the shelter valve board and the rain baffle plate; a partition board is arranged at the upper part between adjacent two lines of ventilation units, and a V-shaped water collecting tank is arranged at the lower part between adjacent two lines of ventilation units; and an electric driving device is arranged on the outer side of the structure trusses and is connected with the shelter valve board through a link mechanism. The thin roof daylighting ventilator has the advantages that the structure is simple and firm, and an additional ventilator supporting structure can be reduced; the ventilation and daylighting effect is good, and the shelter capacity is strong; external air currents can be prevented from flowing backward, and the heat loss in buildings is decreased; and meanwhile, the valve board is closed, so that the height of the ventilator can be reduced, the wind load can be reduced, and the wind damage effect is reduced.

Description

technical field [0001] The invention relates to a building energy-saving ventilator, in particular to a roof thin-type lighting ventilator. Background technique [0002] Building energy saving promotes the extensive application and development of roof daylighting and natural ventilation devices. Among related products, the thin daylighting roof ventilator developed to adapt to the overall appearance of the building and reduce its own wind load has been applied. Thin streamline ventilator and CN202501595U disclosed a kind of assembled light roof ventilation equipment etc. [0003] The thin roof ventilator is a combination of small units similar to the large roof ventilator. The product development is to obtain a similar natural ventilation function of shelter from the wind. However, the technical application of the small thin roof ventilator cannot reflect the same technical characteristics as the large ventilator. . [0004] First of all, the technical performance of the a...

Problems solved by technology

According to the ventilation flow formula Q= mu f m 3 / s, that is, a ventilation device of a certain specification, the ventilation performance is related to its height-to-width ratio, the increase of the overlap reduces the effective flow area F inside the ventilator, and the low (thin) wind-shielding structure increases the ventilation resistance after the exhaust air bypasses increase, flow coefficient mu Decrease, so that the ventilation flow Q is reduced, that is, the ventilation performance of the product is reduced

[0005]Secondly, in order to enhance the wind-shielding performance, the assembled light roof ventilator disclosed in CN202501595U is provided with a translational valve plate device, but since the valve plate device is located at the bottom of the ventilator At the tuyere, when the valve plate is closed, the ventilator will lose its ventilation ability, and external pollutants are more likely to fall on the valve plate with the wind, and the falling snowflakes will melt and drip into the building, causing building pollution
