Description
The utility model relates to a kind of ventilation equipment, particularly a kind of roof ventilation device.
In the prior art as the disclosed roof ventilator of Chinese patent ZL98247527.6, comprise the aspiration column and the aiutage that are interconnected, be rotationally connected by turning cylinder between aspiration column and the aiutage, aiutage is provided with wind rudder member, make aiutage rotate exhaust outlet exhaust with the wind with the wind, the defective of its existence is that room air mainly leans on the mobile gravity-flow ventilation of air, and air-breathing exhaust does not have power, and ventilation is little.Another kind of ventilator of the prior art is electric air exhausting device, and with motor drives fan blade rotation exhaust, the problem of its existence is that consumed power is big, and motor is limited service life, and is not easy to maintenance.
The purpose of this utility model is at the deficiencies in the prior art, and a kind of automatic roof ventilation device that utilizes wind energy for power is provided.
The purpose of this utility model is to reach by following technical scheme.The utility model is a kind of roof ventilation device, comprise the air-breathing base and the aiutage that are interconnected, be rotationally connected between air-breathing base and the aiutage, aiutage is provided with and makes exhaust outlet that aiutage rotated, made the aiutage afterbody by the wind direction wind rudder of exhaust with the wind, be characterized in that the reverse position of aiutage exhaust outlet is provided with air inlet, between air inlet and aiutage, be provided with the air-flow acceleration tube of air outlet less than air inlet.During use, this roof ventilation device is installed in the top of building that needs exhaust, ventilation, the wind rudder causes aiutage to rotate, and makes air inlet over against outdoor air intake direction, and exhaust outlet is exhaust with the wind.According to bernoulli principle, air inlet enters the wind that air-flow quickens tube, obtains quickening because of draught area reduces, and wind speed strengthens the back the air-breathing base that is communicated with aiutage is produced negative pressure, with indoor gas sucking-off, discharge from the exhaust outlet of aiutage with outdoor air-flow.Like this, strengthened the ventilation of roof ventilation device.Ventilation applicable to industry, civil buildings and communal facility.
The purpose of this utility model can also further reach by following technical scheme.Aforesaid roof ventilation device is characterized in being rotationally connected by the turning cylinder member between air-breathing base and the aiutage.Like this, reduced the power consumption when rotating, and simple in structure.
The purpose of this utility model can also further reach by following technical scheme.Aforesaid roof ventilation device is characterized in that the wind rudder is arranged on the top of aiutage.Like this, changed the mode of wind rudder, simplified the structure of roof ventilation device, the effect of wind rudder is strengthened, reduced power consumption simultaneously through transmission mechanism drive aiutage.
The purpose of this utility model can also further reach by following technical scheme.Aforesaid roof ventilation device is characterized in that air-breathing base is that end opening is gone up young air-suction cover greatly.Like this, can impel indoor gas to enter air-breathing base.
The purpose of this utility model can also further reach by following technical scheme.Aforesaid roof ventilation device is characterized in that the exhaust outlet of aiutage is provided with web frame.Like this, can prevent to influence ventilation effect because of the exhaust outlet distortion of aiutage.
The purpose of this utility model can also further reach by following technical scheme.Aforesaid roof ventilation device is characterized in being equipped with on the air-breathing base by motor-operated exhaust fan blade.Like this, in calm, can rotate by motor drives exhaust fan blade and carry out exhaust, ventilation, thereby guarantee the ventilation of roof ventilation device when calm.
The utility model compared with prior art utilizes the wind energy of natural wind to carry out the automatic ventilation ventilation during use, ventilation is big, and is effective, and saves energy is simple in structure, and cost is low, and long service life is easy to install, and is easy to operate.
Accompanying drawing is the cutaway view of the utility model roof ventilation device.
The contrast accompanying drawing further describes implementer's case of the present utility model below.
Embodiment one.In the accompanying drawing, the utility model is a kind of roof ventilation device, comprise the air-breathing base 7 and the aiutage 3 that are interconnected, be rotationally connected between air-breathing base 7 and the aiutage 3, be to be rotationally connected between the air-breathing base 7 of present embodiment and the aiutage 3 by turning cylinder member 6, to reduce power consumption, aiutage 3 is provided with aiutage 3 is rotated by wind direction, make the exhaust outlet 10 wind rudder 1 of exhaust with the wind, the wind rudder 1 of present embodiment is arranged on the top of aiutage 3, thereby simplified the structure of roof ventilation device, the effect of wind rudder 1 is strengthened, the exhaust outlet 10 of aiutage 3 oppositely be provided with air inlet 5, between air inlet 5 and aiutage 3, be provided with air outlet and quicken tube 4 less than the air-flow of air inlet.During use, this roof ventilation device is installed in the top of building that needs exhaust, ventilation, enter the wind that air-flow quickens tube 4 from air inlet 5, because of reducing, draught area obtains quickening, wind speed strengthens the back the air-breathing base 7 that is communicated with aiutage 3 is produced negative pressure, with indoor gas sucking-off, discharges from the exhaust outlet 10 of aiutage 3 with outdoor air-flow, wind rudder 1 can make aiutage 3 rotate, and makes air inlet 5 over against outdoor air intake direction, exhaust outlet 10 exhaust with the wind.Ventilation applicable to industry, civil buildings and communal facility.
Embodiment two.See accompanying drawing, in the above-described embodiment, air-breathing base 7 is that end opening is gone up young air-suction cover 7 greatly, and the exhaust outlet 10 of aiutage 3 is provided with web frame 2, and the exhaust fan blade 8 that is driven by motor 9 is housed on the air-breathing base 7.Like this, can impel indoor gas to enter air-breathing base 7, can prevent simultaneously influences ventilation effect because of exhaust outlet 10 distortion of aiutage 3, and in calm, can drive exhaust fan blades 8 by motor 9 and rotate and carry out exhaust, ventilation, thereby guarantee the ventilation of roof ventilation device when calm.
