High-transmittance, high-efficiency, sand-proof and rain-proof shutter

Abstract

The invention discloses a high-transmittance, high-efficiency, sand-proof and rain-proof shutter. The high-transmittance, high-efficiency, sand-proof and rain-proof shutter comprises a flange frame; the flange frame consists of a lower end plate, an upper flange, a lower flange, a left flange and a right flange; a shielding device is arranged inside the flange frame; the shielding device comprisesan upper front positioning plate, an upper front inserting slot, an upper rear positioning plate, an upper rear inserting slot, a lower positioning plate, a lower front inserting slot, a lower rear inserting slot, a plurality of shutter sheets and a sewage outlet, wherein the upper front positioning plate is arranged at the front side of the internal top of the flange frame; the upper front inserting slot is arranged on the upper front positioning plate; the upper rear positioning plate is arranged at the rear side of the internal top of the flange frame and opposite to the upper front positioning plate; the upper rear inserting slot is arranged on the upper rear positioning plate; the lower positioning plate is arranged at the front side of the internal bottom of the flange frame and opposite to the upper front positioning plate; the lower front inserting slot is arranged on the lower positioning plate and corresponds to the upper front inserting slot in position; the lower rear inserting slot is arranged on the lower flange and corresponds to the upper front inserting slot in position; the tops of the shutter sheets are correspondingly inserted into the upper front inserting slot and the upper rear inserting slot; the bottoms of the shutter sheets are correspondingly inserted into the lower front inserting slot and the lower rear inserting slot; and the sewage outlet is arranged in front of the lower positioning plate and the lower flange.

Description

technical field [0001] The invention relates to a ventilation system louver, in particular to a high-transmittance and high-efficiency sand-proof and rain-proof louver. Background technique [0002] In some areas with strong wind and sand, how to prevent wind, sand and rainwater from entering the room is the guarantee of indoor air quality. [0003] At present, the shutters of the ventilation system are generally designed to keep out rainwater, but the blocking effect is not good for sand and dust or in the case of storms, and some are designed to be electric. Even close it completely, although it can block wind, sand and storm, it can't guarantee the ventilation. [0004] The shutters of the current ventilation system are generally made of opaque aluminum or steel. In some cases where long-term ventilation is required and the ventilation volume is large, it is necessary to install ventilation shutters on the entire wall, which presents a problem of how to daylight Problem...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a high-transmittance and high-efficiency sand-proof and rain-proof louver in order to solve the above-mentioned problems. A shading device is provided. When the ventilation duct turns and advances, the sand, dust and rainwater will be blocked when it hits the small folding edge, and will be blocked downward along the louver arm, collected on the inclined surface of the lower flange and discharged through the sewage outlet. This device can effectively prevent sand, dust and rainwater from entering the room. , can be normally ventilated, and can be used for fresh air intake or non-powered ventilation windows in areas with large wind and sand. At the same time, the louvers are made of PC injection molding, and the colors required by users can be added to ensure the light transmission required by users. Entering the room, while increasing the ventilation, it does not affect the lighting, especially when the entire wall needs to be installed with ventilation louvers, reducing the energy consumption caused by lighting is also a problem that needs to be considered for the ventilation louvers. The device is easy to install and easy to operate. Convenient and simple manufacturing process
