Embodiment Construction
[0012] As an embodiment of the present invention, such as figure 1 As shown, a downhill ventilator includes a ventilator frame 1, and the ventilator frame 1 is formed by welding and threaded connection of a steel bracket. In this embodiment, preferably, the steel bracket is made of stainless steel. . The ventilator frame 1 is provided with an outer guard plate 2, and the ventilator frame 1 is provided with a rainproof plate 3, which is arranged horizontally. In this embodiment, preferably, the ventilator frame 1 is arranged horizontally The cross beam 7 and the rainproof board 3 are fixedly connected to the cross beam 7.
[0013] The wind deflectors 4 are respectively arranged above the two ends of the rainproof plate 3, and two inclined beams 6 are arranged inside the ventilator frame 1 near the two ends of the rainproof plate 3. The two inclined beams 6 are distributed in an "eight" shape. In the embodiment, the inclined beam 6 is fixedly connected to the cross beam 7 by supp...

The invention has large inner ventilation area, the ventilation efficiency is high and the practicability is good.
Description
Technical field [0001] The invention relates to a roof ventilation device, in particular to a downhill ventilator. Background technique [0002] In today's large workshops and large smelting workshops that require air exchange, roof ventilators are often installed to use temperature differences to exhaust the overheated air inside the house. The roof ventilators allow the overheated air in the house to be discharged from the house through natural wind. No human operation is required for 24 hours, and no electricity is required. However, the structural design of the existing roof ventilators has some defects. The rain-proof panels of the existing roof ventilators are all herringbone structures, which occupy most of the area of the roof ventilators, resulting in a small ventilation area inside the ventilators. , The ventilation efficiency is low. Summary of the invention [0003] In view of the above-mentioned problems in the prior art, the present invention provides a downhill ...
