Detailed Description

The present application is described in further detail below with reference to fig. 1.

The embodiment of the application discloses a ventilated double-layer roof.

Referring to fig. 1, a ventilated double roof includes a base concrete layer 1, a supporting wall 11, an upper roof cover plate 2, which are arranged from bottom to top in a vertical direction; the supporting walls 11 are fixed on the foundation concrete layer 1 through concrete, the lower roof cover plate 3 is fixedly bonded between the supporting walls 11 on the upper side of the foundation concrete, the upper roof cover plate 2 is fixed on the supporting walls 11 through concrete, and a ventilation cavity 4 is formed between the lower roof cover plate 3 and the upper roof cover plate 2. The supporting wall 11 on one side of the ventilation cavity 4 is provided with a hole, a ventilation fan 41 is arranged in the hole, and the supporting wall 11 on the other side of the ventilation cavity 4 is provided with an air outlet 42.

The action of the ventilation fan 41 drives the air to flow into the ventilation cavity 4, and then the air in the ventilation cavity 4 is blown out from the air outlet 42, so that new air is introduced into the internal circulation of the ventilation cavity 4 to cool the basic concrete layer 1, the indoor temperature of the top floor is reduced, the influence of sun exposure on the house of the top floor is reduced as much as possible, and the house of the top floor is suitable for people to live in.

In order to prevent moisture from entering the ventilation cavity 4 when raining as far as possible, the upper roof cover plate 2 is provided with the rain baffle plate 21, one side of the rain baffle plate 21, which is close to the upper roof cover plate 2, is fixedly connected with the upper roof cover plate 2 through reinforced concrete, one side of the rain baffle plate 21, which is far away from the upper roof cover plate 2, is lower than one side of the rain baffle plate 21, which is close to the upper roof cover plate 2, so that rainwater on the upper roof cover plate 2 can flow down smoothly, meanwhile, the rain baffle plate 21 is obliquely arranged to block rainwater as far as possible, and rainwater is prevented from entering the ventilation cavity 4 as far as possible, and influence on ventilation is caused.

In order to prevent debris such as winged insects from entering the ventilation cavity 4 as much as possible and reduce pollution in the ventilation cavity 4, the two sides of the ventilation cavity 4 are respectively provided with an air inlet filter screen 43 and an air outlet filter screen 44, the air inlet filter screen 43 is positioned on one side of the ventilation fan 41, and the air outlet filter screen 44 is positioned on one side of the air outlet 42. The air inlet filter screen 43 is fixed on the supporting wall 11 through adhesion fixed connection, the other end with the weather shield 21, and one side that makes the air inlet filter screen 43 keep away from the ventilation fan 41 is less than the side that is close to the ventilation fan 41, makes winged insect and other debris difficult to enter into in the ventilation chamber 4. The air outlet filter screen 44 and the air inlet filter screen 43 are arranged the same, so that flying insects and other impurities are difficult to enter the ventilation cavity 4 through the air outlet 42, and the cleanness in the ventilation cavity 4 is kept.

Since the ventilation fan 41 brings outdoor air into the ventilation chamber 4, dust is easily accumulated at the intake air filter 43. In order to keep the air inlet filter screen 43 clean and not affect ventilation, a dust removal cylinder 5 is arranged on one side of the air inlet filter screen 43 away from the ventilation fan 41, the body of the dust removal cylinder 5 is fixed on the rain baffle plate 21 through a bolt, and the piston rod of the dust removal cylinder 5 is parallel to the air inlet filter screen 43; the end part of the piston rod of the dust removing cylinder 5 is provided with a dust removing brush plate 51, the dust removing brush plate 51 is fixed on the piston rod of the dust removing cylinder 5 through a bolt, and one side of the dust removing brush plate 51 close to the air inlet filter screen 43 is abutted against the air inlet filter screen 43.

The dust removing cylinder 5 drives the dust removing brush plate 51 to brush the air inlet filter screen 43, so that the air inlet filter screen 43 keeps ventilation, and the roof ventilation effect can be well kept.

Because the flow of the interior air of ventilation chamber 4 can produce the noise, for reducing the influence that this noise caused in to the house, be equipped with down between roof apron 3 and basic concrete layer 1 and inhale the sound and fall the layer of making an uproar 6, inhale the sound and fall the layer of making an uproar 6 and all pass through sticky fixed connection with lower roof apron 3 and basic concrete, inhale the sound and fall the layer of making an uproar 6 and make for inhaling the sound and fall the material of making an uproar. When the sound of the air flow in the ventilation cavity 4 is transmitted to the indoor, the sound can be blocked as much as possible by the sound absorption and noise reduction layer 6, the influence on the indoor is avoided as much as possible, and the indoor is kept quiet as much as possible.

In order to provide electric energy for the ventilation fan 41 and save energy consumption, a layer of solar panel 7 is laid on the upper roof cover plate 2, and the solar panel 7 is connected with the ventilation fan 41 through a conducting wire to drive the ventilation fan 41 to rotate, so that energy consumption is saved.

In order to prevent the solar panel 7 from being damaged by falling objects in the air as much as possible, a plurality of crash bars 72 are fixed on the upper roof cover by welding, and the upper ends of the crash bars 72 are fixed on the crash net 71 by welding. When falling objects, such as hail, exist in the air, the falling objects are firstly intercepted by the anti-collision net 71 to protect the solar panels 7.

The implementation principle of the double-deck roof of ventilation of the embodiment of this application does:

the method mainly comprises the following steps: and (3) ventilating and cooling, wherein the ventilating fan 41 acts to drive air to flow into the ventilating cavity 4, and then the air in the ventilating cavity 4 is blown out from the air outlet 42, so that new air is introduced into the internal circulation of the ventilating cavity 4 to cool the basic concrete layer 1, the indoor temperature of the top floor is reduced, the influence of sun exposure on a top floor house is reduced as much as possible, and the top floor house is suitable for people to live in.

Auxiliary step 1: the solar panel 7 converts solar energy into electric energy, and then the electric energy is transmitted to the ventilation fan 41 through a lead to drive the ventilation fan 41 to rotate, so that energy consumption is reduced.

And (2) auxiliary step: and during dust removal, the dust removal cylinder 5 drives the dust removal brush plate 51 to brush the air inlet filter screen 43, so that the air inlet filter screen 43 keeps ventilation, and the roof ventilation effect can be well kept.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
