2, keep CO necessary in the greenhouse
2Concentration; Discharge indoor steam, reduce indoor air humidity; Impel indoor air flows, promote the gas exchange in the plant community, be tending towards even.Roof powerless ventilation device principle is by the swabbing action that the poor and outdoor natural wind of thermal pressure that the temperature difference inside and outside the greenhouse produces produces room air to be discharged to the outdoor ventilation that realizes.Air themperature is higher than outdoor temperature in the greenhouse, and the hot air rising in the greenhouse is discharged the greenhouse to top, greenhouse along air duct, has formed a negative pressure at inside greenhouse simultaneously, and outdoor Cryogenic air adds to indoor from bottom side window or the ventilating opening in greenhouse; Or utilize extraneous wind-force in the swabbing action that the roof air duct forms the suction of the hot-air in the greenhouse to be taken to outside the greenhouse, outdoor Cryogenic air adds to indoor from bottom side window or the ventilating opening in greenhouse, finished ventilation, realize the regulation and control air condition, this device does not need artificially to arrange driving power.Existing Unpowered roof fan normal operation metal shell air duct cooperates the combination of rotatable or fixing blast cap to realize, the general metal material that adopts comes processing and fabricating, its shortcoming is except complete machine weight is large, its air outlet is in open state, can not carry out at any time the people for controlling according to the inside greenhouse environmental requirement, and extraneous sleet, dust, pest also enter in the greenhouse from air duct easily, cause the harm to raise crop in the greenhouse and livestock and poultry, metal material also causes corrosion and damage easily under hot and humid condition simultaneously.The problem of switching inconvenience during the use of prior art ubiquity, it is tight how to solve closure when closure of convenient while of Unpowered roof fan switching, is the technical problem that the technical staff needs to be resolved hurrily.
The utility model content
The technological deficiency that exists in order to solve prior art, the purpose of this utility model is to provide a kind of Unpowered roof fan, and it can conveniently be installed, and is lightweight, corrosion-resistant, has reduced the shading of blower fan, and it is convenient to open and close, good airproof performance.
To achieve these goals, the technical scheme of a kind of Unpowered roof fan of the utility model is:
A kind of Unpowered roof fan comprises air duct, pulling rope, air-out mouth mask, guide post, compression spring, guard ring, bracing frame, wherein:
Air duct end opening outer rim has fixture, air duct end opening fixing support rack, and air duct is suitable for reading to have to inward flange;
It is suitable for reading that the air-out mouth mask inserts air duct, air-out mouth mask top is umbrella, the umbrella top perimeter has to lower hem, this flanging can be fastened on the air duct outside suitable for reading, and periphery has many perpendicular muscle, and perpendicular muscle lower end is connected with guard ring, guard ring can be fitted with air duct inward flange suitable for reading, air-out mouth mask center fixed guide pole, cover pressure spring on the guide post, the hole of guide post lower end in the middle of from the bracing frame passed; Pulling rope is connected on the air-out mouth mask.
Pulling rope one end passes in the hole of a side from the bracing frame, passes the hole on the guide post again, and the end is fixed on the bracing frame opposite side.
Pulling rope is shaped as Y shape, and its both upper ends thereof is separately fixed on the air-out mouth mask.
Air duct, air-out mouth mask and guard ring are plastic material, and wherein the air-out mouth mask is the transparent plastic material.
Owing to adopt technique scheme, air duct, air-out mouth mask and guard ring adopt the plastic material weight reduction, and be corrosion-resistant, long service life, and the air-out mouth mask adopts transparent plastic, has increased the light transmittance in greenhouse, has improved the availability in greenhouse; The activity of air-out mouth mask be contained in the suitable for reading of air duct, when needing to ventilate, unclamp pulling rope, the elastic force of compression spring upwards boosts the air-out mouth mask to come, in the greenhouse air from the air duct center through outside the space delivery chamber between the perpendicular muscle of air-out mouth mask periphery, in the time of need to closing, by people's pulling rope of manually leaving behind, the drive guide post moves downward, make the air-out mouth mask that is connected on the guide post be fastened on downwards air duct suitable for reading on, the lower hem of air-out mouth mask periphery is so that closed tight, pulling rope can be fastened on other members of greenhouse, keep air-out mouth mask closure state, air-out mouth mask umbrella top can make that sleet is smooth and easy to be flow down.Pulling rope can also be designed to Y shape on the air-out mouth mask, and upper two ends are fixed with the air-out mouth mask respectively, leaves behind when stopping to ventilate and fixing pulling rope, closes the air-out mouth mask.
