Background technique

For some buildings, especially computer rooms or factory buildings, ventilation and rain protection are very critical, and even directly related to the operation and production safety of computer rooms or factories, equipment. In order to make the machine room or factory building have good ventilation and rainproof effects, the prior art has appeared longitudinal sunken skylights on both sides, horizontal sunken skylights, central well skylights, side well skylights, etc. However, these skylights all have poor ventilation effect or poor rainproof effect, so there are hidden dangers to varying degrees.

Utility model content

The problem to be solved by the present invention is to provide a device with good ventilation and rainproof effects to solve the ventilation and rainproof problems of large buildings, especially machine rooms or factory buildings.

In order to solve the above problems, the technical solution provided by the utility model is:

A horizontal rainproof device, said device comprising blades, side panels, upper water receiving side grooves, lower water receiving side grooves, and drainage grooves, the longitudinal section of said blades is arc-shaped, and said upper water receiving side grooves are fixed On the convex surface of the blade, the lower water receiving side groove is fixed on the bottom of the blade, the bottom of the lower water receiving side groove is fixed on the drainage groove, and the bottom of at least one of the side pieces is provided with a drainage groove, There are openings at the joints between the side panels and the upper water-connecting side groove and the lower water-connecting side groove.

Preferably, at least one of the two ends of the lower connection tank has an opening, and the opening end is located at the top opening of the drainage tank.

Preferably, there are at least two blades, and the blades are bent in the same direction.

Preferably, there are at least two side panels.

Preferably, there is at least one drainage groove.

The beneficial effect of the utility model is that: in the horizontal rainproof shutter, the rainwater is separated from the main flow state and attached to the blades. Then, the rainwater flows into the upper water receiving side groove or the lower water receiving side groove along the blade. Finally, there is a drainage tank for unified collection. The ventilation of the horizontal rain-proof louvers with vertical openings designed by the utility model prevents or minimizes the infiltration of rainwater, and effectively ensures the ventilation and rain-proof of the building.

Detailed ways

In order to describe the content of the present invention more clearly and completely, the concept of the present utility model will be described below in conjunction with specific embodiments. Of course, the provided embodiments are intended to illustrate the concept of the utility model, and are not all of the design solutions of the utility model, and should not be regarded as limitations of the design content of the utility model. Under the enlightenment of the content provided, any scheme made belongs to the protection scope of the present utility model.

A horizontal rainproof device, the device comprises a blade 1, a side piece 2, an upper water receiving side groove 3, a lower water receiving side groove 4, and a drainage groove 5, the longitudinal section of the blade 1 is arc-shaped, and the The upper water receiving side groove 3 is fixed on the convex surface of the blade 1, the lower water receiving side groove 4 is fixed on the bottom of the blade 1, the bottom of the lower water receiving side groove 4 is fixed on the drainage groove 5, and the side piece The bottom of at least one of the side pieces 2 is provided with a drainage groove 5, and the connection between the side piece 2 and the upper water receiving side groove 3 and the lower water receiving side groove 4 has an opening. When in use, the side panels are fixed to the opening at the top of the building, parallel or nearly parallel to the horizontal plane, and the main direction of the blades is perpendicular to the gutter, thereby forming a horizontal ventilation defense device. In this device, there is a gap between the blades, which can be used for ventilation. And when it rains, when the rainwater falls on the concave surface of the blade, it can flow into the water receiving side groove through the groove of the blade, and when the rainwater falls on the convex surface, it can flow to the water receiving side groove down along the convex surface.

The utility model can be inclined along with the air vent on the top of the building according to the requirements of the building. In addition, the blades can be bent in the same direction as the air flow according to the direction of the vent and the air flow, so as to reduce the pressure loss.

In order to facilitate the collection of rainwater, at least one of the two ends of the lower sink has an opening, and the open end is located at the top opening of the drainage tank.

In order to adapt to vents of different specifications, there are at least two blades, and the blades are bent in the same direction.

There are at least two side panels, and the drainage grooves can be designed according to the specifications of the vents, generally more than two, so that the drainage grooves play a supporting role without affecting the ventilation because they are too dense.

The function of the side groove is to collect rainwater on the top of the concave-convex surface of the blade. The side groove is at least one, and may also be formed by overlapping and dislocation.

After testing, when the rainfall intensity is 75mm/hour and there is no wind pressure in the vertical direction, the horizontal rain shutter system can achieve the following water penetration efficiency values: 100% when the airflow is in the discharge state; 100% when there is no airflow; 2.5 meters It is 100% when the air intake speed is 5 m/s; it is 98% when the air intake speed is 5 m/s. When the intake or exhaust velocity is 5 m/s or below, the pressure loss is not greater than 30 Pascals (Pa), and the noise power is not greater than 55 decibels.

When the rainfall intensity is 200 mm/h and there is no vertical wind pressure, the horizontal weatherproof shutter system can achieve the following water penetration efficiency values: 100% when the air flow is in the discharge state; 100% when there is no air flow; 2.5 m/s It is 100% when the air speed is 5 m/s; it is 98% when the air speed is 5 m/s. When the intake or exhaust velocity is 5 m/s or below, the pressure loss is not greater than 30 Pascals (Pa), and the noise power is not greater than 55 decibels.

The "water infiltration efficiency" referred to here is defined as the ratio of the rainwater collected by the louvers to the total amount of rainwater under air flow conditions.
