Description

A horizontal rainproof ventilation shutter

technical field

The utility model relates to the construction field, in particular to a horizontal rainproof and ventilated louver.

Background technique

Shutters are a style of windows that originated in China. Shutters can be used not only as a decoration, but also as a ventilation and light transmission, which are often used in modern buildings. Urban underground complexes are popular buildings to alleviate urban congestion, including three types: city center, transportation hub, and protection and reconstruction. As a part of the ventilation environment control system of the urban underground complex, the ground wind pavilion is an important channel for air communication between the underground and the ground. Ground wind pavilions can be divided into open low wind pavilions, high wind pavilions, and main body top-out wind pavilions. Considering the requirements of urban landscape, the exposed low-wind pavilion has little impact on the surrounding environment and landscape vision, and the architectural form is simple, the ventilation is large, and the cost is low, which is easy to obtain public recognition. Considering rain prevention, backflow and other issues, drainage facilities and safety devices should be installed at the entrance of the wind pavilion.

At present, ordinary aluminum alloy grille is usually used as the only rainproof and drainage facility at the entrance of the wind pavilion. Although this can achieve a good ventilation and ventilation effect, the grid plate of the grille generally adopts a simple sheet structure, and the installation form of the grid plate is simple, so the rainproof effect and sewage discharge capacity are relatively poor, resulting in high maintenance in the later period of the open low wind pavilion, which makes the design scheme of the open low wind pavilion unable to be widely used.

Therefore, the applicant is committed to providing a horizontal rainproof and ventilated louver, which has a reasonable structural design, good ventilation and air permeability, and a remarkable rainproof and sewage discharge effect.

Utility model content

The purpose of the utility model is to provide a horizontal rainproof and ventilated louver, which has a reasonable structural design, good ventilation and air permeability, and a remarkable rainproof and sewage discharge effect.

In order to solve the above technical problems, the utility model provides a horizontal rainproof and ventilated louver, comprising a base plate for fixing the louver on the base and a frame set on the base plate, the frame includes a pair of first borders and a pair of second borders;

It also includes a plurality of louvers arranged in the frame and arranged side by side with the second frame in the horizontal direction, and the two sides of the louvers in the width direction are respectively connected to the first frame;

The louvers have a recess, and the recesses are used to change the movement direction of rainwater after entering the louvers;

The sides of the louver in the length direction are bent to form a first groove, and the first groove is used to collect rainwater entering the louver and drain it into the first frame;

The bottom of the first frame is provided with an opening for draining rainwater in the first frame to the base plate.

The horizontal rain-proof ventilation louver of the utility model has remarkable rain-proof and sewage discharge effects. When the rainwater enters the louver, its movement direction changes on the outer surface of the concave part of the louver, falls into the first groove of the adjacent louver, and then drains into the first frame through the first groove, and then passes through the The opening at the bottom of the first frame drops into the base plate, thereby draining rainwater to the outside.

Preferably, a second groove is provided on the outer surface of the recess of the louver, and the second groove is used to collect rainwater entering the louver and guide it into the first frame.

The second groove body is arranged between the louver blades, and when the rainwater passes through the recess of the louver and changes direction and cannot fall into the first groove body of the adjacent louver blades, it can fall into the second groove body. The second groove body further enhances the ability of the louvers to prevent rain and sewage.

Preferably, a third groove is provided at the joint between the base plate and the frame.

The third tank forms a structure in the form of a ridge between the base plate and the frame body, and when there is a lot of rainwater, it can effectively prevent the rainwater discharged to the base plate from flowing back into the shutter.

Preferably, the first frame is detachably arranged on the base plate, and the first frame is detachably connected to the louvers.

The first frame is detachably set to facilitate inspection and maintenance of the blinds.

Preferably, rubber sealing strips are provided at the joints between the frame body and the base plate, and at the joints between the frame body and the louvers.

The rubber sealing strip improves the airtightness of the joints of the shutters, preventing rainwater from seeping through.

Preferably, the louver is also provided with a mesh structure on the side close to the outdoor.

Setting the mesh structure can effectively prevent solid debris from falling into the blinds with rainwater, causing blockage.

Preferably, the plurality of louvers are arranged equidistantly in the horizontal direction.

The utility model has the advantages of reasonable structure, good ventilation and air permeability, and remarkable rainproof and sewage discharge effect.
