Abstract
The utility model discloses a roof ventilator which is suitable for large-sized power plants, aluminium factories or other workshops of which the roofs are needed to be ventilated outwards. The utility model comprises a circle arc support frame, a crossbeam, a Y-shaped support frame, a base and at least two layers of baffles, wherein the support frame is fixed on the base; a layer of color steel tiles is coated outside the support frame; one end of the two valve plates is hinged at the center of a transverse beam of the base, and a control device is arranged on the end and is used for freely adjusting angle changes of the valve plates to control the ventilation quantity of the ventilator. The utility model is characterized in that the position of the baffle at the outer layer exceeds the circular arc support frame; the baffle at the inner layer exceeds the position of a hole mouth of the base; even the appearance of strong wind and heavy rain can not generate the phenomena of rain leakage and rain flying, and water can not leak into the hole; the utility model thoroughly solves the defects of the phenomena of the rain leakage and the rain flying. The product adopts a natural ventilation structure; making use of negative pressure action, the utility model can be always kept in a ventilation state; the utility model can save cost and improve work efficiency.
Description
Technical field: the utility model relates to a kind of ventilator, particularly relates to a kind ofly to be applicable to that tall and big factory building needs a kind of roofing ventilator of roof to separate ventilation.
Technical background: a kind of roof ventilator that the utility model relates to mainly is applicable between large power plant, aluminium manufacturer or other large cars and uses.According to the Searches of Patent Literature, various roof ventilators are arranged in this technical field, as the described a kind of roof ventilator of Chinese patent ZL02264416.4 (as shown in Figure 2), this roof ventilator is made up of the bracing frame and the several layers weather shield of steel construction, design has support bar on described valve plate, the one end hinge joint of support bar is on valve plate, the other end can be supported on the crossbeam, can change the ventilation of controlling ventilator by the angle that the height of regulating support bar is adjusted valve plate arbitrarily, when support bar was adjusted to maximum height, valve plate can form the closed area with the internal layer weather shield.The described a kind of roof ventilator of Chinese patent ZL00219448.1 for another example, it also is made up of the bracing frame and the several layers weather shield of steel construction, it is to regulate the angle of adjusting valve plate by motor to change the ventilation of controlling ventilator, all there is following shortcoming in these two kinds of roof ventilators: 1. because the too short hole of not blocking fully of second layer weather shield, can stop up because of dust in the gutter gutter channel below the long-term use weather shield, thereby make rainwater in the hole, be easy to generate the roof leaking phenomenon; 2. because the chevron shaped beam wedge angle degree between the second road weather shield is too little, easily produce the rain phenomenon of wafing; 3. because the first road weather shield is too short, also easily produce the rain phenomenon of wafing.
Summary of the invention: the utility model provides a kind of new type roof ventilator, can solve the defective that has the roof leaking and the rain phenomenon of wafing in the above various designs in essence ground.
The purpose of this utility model is achieved in that a kind of natural roof ventilator is the bracing frame by steel construction, base and at least two-layer weather shield form, on the bracing frame firm banking of described steel construction, the center of described two valve plate one ends hinge joint base crossbeam, design has control device on it, can adjust the angle of valve plate by control device arbitrarily, and change the ventilation of controlling ventilator by the angle of valve plate, it is characterized in that: the position of described outer weather shield should surpass the circular arc bracing frame, and described internal layer weather shield should surpass the position at base hole.
The utility model compared with prior art has following advantage:
1, the utility model has adopted the gravity-flow ventilation structure, utilizes suction function, can remain ventilation state, can save cost widely, improves work efficiency.
2, the utility model can be adjusted the angle of valve plate by control device arbitrarily, and change the ventilation of controlling ventilator by the angle of valve plate, and during work, valve plate and internal layer weather shield form the closed area, can not produce the eddy current and the globule when hot-air is risen.
3, the utility model is because the position of outer weather shield surpasses the circular arc bracing frame, and the internal layer weather shield surpasses the position at base hole, therefore can not have the appearance of the roof leaking and the rain phenomenon of wafing.
4,, can not produce the roof leaking and the rain phenomenon of wafing even strong wind and heavy rain occurs owing to the chevron shaped beam wedge angle degree that has increased between the internal layer weather shield yet.

The specific embodiment: a kind of roofing ventilator is by including circular arc bracing frame 3, crossbeam 4, herringbone beam 5 bracing frame, base 12 and two-layer at least weather shield 1 and 2 compositions, on the described bracing frame firm banking 12, the outside is surrounded by the color steel of one deck watts 9, the center of described two valve plate 7 one ends hinge joint base crossbeam 13, design has control device 14 on it, can change the ventilation of controlling ventilator by the angle that control device 14 is adjusted valve plate 7 arbitrarily, it is characterized in that: below described internal layer and outer weather shield 1 and 2, all be provided with seven font gutters 10, described gutter 10 is connected with gutter channel 8, by gutter channel 8 water is drawn, the position of described outer weather shield 2 should surpass circular arc bracing frame 3, described internal layer weather shield 1 should surpass the position at base 12 holes, can not produce the roof leaking and the rain phenomenon of wafing even strong wind and heavy rain occurs yet, be exactly that water also can not drain in the hole, can solve the defective that has the roof leaking and the rain phenomenon of wafing in the above various designs in essence ground.
For this ventilator when strong wind and heavy rain occurring can not produce the rain phenomenon of wafing yet, can increase the chevron shaped beam wedge angle degree 6 between the internal layer weather shield, its scope is at 110 ℃--between 150 ℃.
For this ventilator when strong wind and heavy rain occurring can not produce the rain phenomenon of wafing yet, circular arc bracing frame 3 can be extended to both sides respectively.
Described control device 14 can adopt motor, also can be designed to support bar, the hinge joint of one end of support bar is on valve plate 7, and the other end can be supported on the base crossbeam 13, can change the ventilation of controlling ventilator by the angle that the height of regulating support bar is adjusted valve plate 7 arbitrarily.
In order to increase the intensity of bracing frame, on the skeleton of described outer weather shield 2, be added with connecting rod 11.
