Description

Technical Field

[0001] The utility model relates to the technical field of building ventilation, in particular to a building ventilation rainproof structure. Background Art

[0002] Building structure is the name given to various structural forms in architecture. Generally speaking, it also includes the behaviors covered or derived from these structural forms. The function of the structural system in the field of architecture is different from that in fields such as civil engineering or mechanical engineering. Because architecture has its artistic significance, it must start from architectural aesthetics. The structural system is an element that assists in achieving aesthetic purposes and also has mechanical functions. Building ventilation is divided into natural ventilation and mechanical ventilation, which means that the dirty air in the building is directly or purified and discharged to the outside, and then fresh air is added to keep the indoor air environment in line with hygiene standards.

[0003] The ventilation components of existing house buildings are basically divided into windows and roof ventilation components. Windows are the most basic ventilation and lighting components, while roof ventilation components are usually connected to the ventilation ducts in the house to keep the air circulating in the building at all times. Although the existing roof ventilation basically adopts the setting of inclined grilles to reduce the entry of rainwater into the ventilation openings, when encountering heavy rain weather with high wind speed and large amount of rain, rainwater will enter the interior of the building along the ventilation ducts, thereby affecting the use of the building.

[0004] To this end, we designed a building ventilation and rainproof structure. Utility Model Content

[0005] The utility model aims to provide a building ventilation and rainproof structure in order to solve the problem of low efficiency in the prior art.

[0012] Preferably, the flashing plate is fixedly connected to the outer wall of the ventilator by welding.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model provides auxiliary leaves and multi-section rods, so that when the ventilation body encounters heavy rain, the grille leaves can be quickly changed according to the wind speed and direction, and the phenomenon of rainwater entering the ventilation duct can be reduced to the greatest extent. At the same time, the multi-section rod can reduce the jamming phenomenon when the conversion knob is turned, and the transmission efficiency between the multi-section rods can be improved through the rotating shaft, so as to avoid the jamming of the multi-section rods and the inability to adjust the grille leaves. Compared with the existing technology, it can effectively reduce the backflow of rainwater into the building, thereby reducing the inconvenience during the use of the building.

[0021] Reference Figure 1-Figure 4 A building ventilation and rainproof structure includes a roof body 1, which is the top floor of a building in the prior art, and the top floor is provided with ventilation ducts. A ventilation body 2 is a ventilation and rainproof component in the prior art, which is mainly used for ventilation effect in the building and reduces the infiltration of rainwater. A connecting rod 3 is a metal fixing rod in the prior art and is fixed to the inner wall of the ventilation duct in the roof body 1 by welding. There are two connecting rods 3, which can improve the stability of the ventilation and rainproof component.

[0022] A plurality of grille leaves 13 for reducing the entry of rainwater are symmetrically arranged on the ventilation body 2. The grille leaves 13 are made of aluminum alloy sheets, and a waterproof layer is coated on the surface of the aluminum alloy sheets to maximize the service life of the grille leaves 13. The grille leaves 13 are mainly used to reduce the entry of rainwater into the ventilation duct. A frame for arranging the grille leaves 13 is provided on the ventilation body 2. A plurality of conversion plates 11 for clamping the grille leaves 13 are provided on the frame. The conversion plates 11 are mainly used to change the current angle of the grille leaves 13 so that the grille leaves 13 are obliquely angled and overlap with other grille leaves 13 to form a rainproof surface to reduce the entry of rainwater into the ventilation duct. Secondly, they are used to clamp the grille leaves 13.

[0023] A conversion button 5 for adjusting the opening and closing of the grille blades 13 is provided on the connecting rod 3. The conversion button 5 is a transmission component. The grille blades 13 are rotated according to the rotational force of the wind speed. A sealing button 6 for changing the rotation is provided on the conversion button 5. The sealing button 6 is arranged above the ventilation body 2, and is the source of the power for adjusting the grille blades 13. The bottom of the sealing button 6 is against the top of the ventilation body 2. A sealing gasket is provided at the connection between the sealing button 6 and the ventilation body 2 to prevent rainwater from entering the ventilation duct. One end of the sealing button 6 is fixedly connected to the connecting rod 3 through the rotating rod 4. One end of the sealing button 6 is columnar, and part of the force can be transmitted to the rotating rod 4, and then transmitted to the connecting rod 3 and the roof 1 by the rotating rod 4. Auxiliary leaves 7 for changing according to the wind direction are symmetrically provided on the sealing button 6. The auxiliary leaves 7 are used to capture wind speed and direction, and are the power source for adjusting the angle of the grille blades 13.

[0024] A multi-section rod 8 for connecting the grille leaves 13 is provided on the conversion button 5. The multi-section rod 8 is the main component for connecting the conversion button 5 to the grille leaves 13. The multi-section rod 8 is fixedly connected to the conversion button 5 through fasteners. Two rotating shafts 9 for improving the adjustment efficiency are provided on the multi-section rod 8. The rotating shaft 9 is an auxiliary component, and a compression spring is provided inside it to assist the transmission force of the multi-section rod 8, and reset the multi-section rod 8 when the wind speed decreases, so that the grille leaves 13 are reopened. The multi-section rod 8 is fixedly connected to the conversion plate 11 through an auxiliary rod 10, and the auxiliary rod 10 is an elastic component.

[0025] The ventilation body 2 is provided with a plurality of connecting columns 12 for limiting the grille leaves 13. The connecting columns 12 are fixing components of the grille leaves 13 in the frame. The connecting columns 12 are fixedly connected to the conversion plate 11 through fasteners. The fasteners are auxiliary fixing components, and one end of the connecting column 12 is rotatably connected to the inner wall of the ventilation body 2 through a bearing.

The rain shield 14 is fixedly connected to the outer wall of the ventilation body 2 by welding. Welding can improve the connection strength between the rain shield 14 and the ventilation body 2.

[0027] The working principle of the utility model is as follows: when the local weather encounters heavy rain, the auxiliary leaves 7 will adjust the angle of the grille leaves 13 under the impetus of wind speed and direction, so that the grille leaves 13 are quickly closed to reduce the entry of rainwater. When the wind speed and direction weaken, the rotating shaft 9 will rebound due to the setting of the compression spring, forcing the grille leaves 13 to open and allowing the auxiliary leaves 7 to reset.
