Abstract
An unpowered hood comprises a structural support. Arc-shaped outer guard plates and ditches are symmetrically on the two sides of the structural support, end plates are arranged at the two ends of the structural support, and an air inlet and an air outlet are formed in the portion, between the outer guard plates on the two sides, of the bottom of the structural support and in the portion, between the outer guard plates on the two sides, of the upper end of the structural support respectively. The unpowered hood is characterized in that a V-shaped rain baffle wider than the air inlet and the air outlet is arranged in the middle in the structural support, the two ends of the V-shaped rain baffle are led out of the end plates respectively, drain outlets are formed in the portions, corresponding to the lead-out positions of the V-shaped rain baffle, of the end plates, and a wind shelter plate capable of closing the air outlet is hinged to the upper end of the structural support. The unpowered hood has the advantages that the effective ventilation area is large, the ventilation effect is good, weather changes does not need to be worried in the ventilation process, and ventilation of the product is not influenced by external wind power; motion abrasion is small, and the service life is long; because the air outlet can be closed through the wind shelter plate, heat loss caused by ventilation of a building is reduced, and back flow of rain and snow caused by weather changes does not need to be worried; the manufacturing technology is simple, the manufacturing cost is low, and the unpowered hood is easy to use and popularize.
Description
Technical field
The utility model relates to a kind of natural ventilation equipment, particularly a kind of unpowered blast cap.
Background technology
As small-sized monomer ventilating product, Application in Building adopts rotary unpowered blast cap more.Along with popularizing that this product is used, product shows many-sided application technology problem especially.Mainly contain: 1, blast cap rotation gives power ventilation illusion, in fact product still belongs to not wind sheltering type natural ventilation equipment, it is larger that ventilation is affected by natural cause, and rotary unpowered blast cap available ventilation area is little and flowing resistance coefficient is large, makes the draught capacity of product low; 2, long-term constantly rotation must move formula damage, and application life is short; 3, product and roofing are installed in conjunction with seepage often occurs; 4, product can not be closed insulation.
The said goods technical problem makes much to apply building ventilation deficiency, and Environment Inside the Building does not reach air-conditioning requirement, and campaign-styled damage and often generation seepage make user have to carry out roofing transformation, cause great economic loss thus to enterprise.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of unpowered blast cap will be provided, product has with natural wind adjusting rain and snow function, during ventilation without worrying Changes in weather, product ventilates and not affected by external wind, can close and reduce building ventilation thermal loss, product ventilation effect is good, and the simple cost of manufacturing process is low, long service life.
The unpowered blast cap that the utility model relates to, comprise structure stand, in structure stand bilateral symmetry, be provided with arc outer casing, the bottom that is positioned at outer casing in structure stand both sides is provided with ditch, at structure stand two ends, be provided with end plate, structure stand bottom and upper end form respectively air intake and air outlet between the outer casing of both sides, its special character is: in structure stand, middle part is provided with the V-type weather shield that width is greater than air intake and air outlet, the two ends of V-type weather shield are drawn by end plate respectively, on end plate, the corresponding described V-type weather shield place of drawing is provided with outfall, in structure stand upper end, be hinged with the wind-blocking board that air outlet can be closed.
Above-mentioned unpowered blast cap, also can swing with the wind in plumbness when described wind-blocking board ventilates, and to realize nature, regulates rain and snow to pour in down a chimney ability.
Above-mentioned unpowered blast cap, described ditch and outer casing are integrated, so that install.
The utility model has the advantages that: 1, available ventilation area is large, and flowing resistance is little, ventilation effect is good, and during ventilation, without worrying Changes in weather, product ventilates and not affected by external wind; 2, motion wearing and tearing are little, long service life; 3, by wind-blocking board, can close air outlet and reduce building ventilation thermal loss, without worrying, because sleet occurs Changes in weather, pour in down a chimney; 4, product easy to leak not after installing, the simple cost of manufacturing process is low, is easy to application popularization.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
In figure: structure stand 1, ditch 2, outer casing 3, end plate 4, outfall 401, V-type weather shield 5, air outlet 6, wind-blocking board 7, air intake 8.
The specific embodiment
As shown in the figure, this is unpowered, and blast cap has a structure stand 1, in structure stand 1 bilateral symmetry, is fixed with arc outer casing 3, and the bottom that is positioned at outer casing 3 in structure stand 1 both sides is provided with ditch 2, and ditch 2 is integrated with outer casing 3, so that install.Described is fixed with respectively end plate 4 in structure stand 1 rear and front end, structure stand 1 bottom and upper end form respectively an air intake 8 and an air outlet 6 between the outer casing 3 of both sides, at the interior middle part of structure stand 1, be fixed with the V-type weather shield 5 that width is greater than air intake 8 and air outlet 6, the two ends of V-type weather shield 5 are drawn by end plate 4 respectively, on end plate 4, corresponding described V-type weather shield 5 places of drawing are provided with outfall 401, in structure stand 1 upper end, be hinged with the wind-blocking board 7 that air outlet 6 can be closed, the jointed shaft of wind-blocking board 7 is positioned at its center, when ventilating, wind-blocking board 7 also can swing with the wind in plumbness, to realize nature, regulate rain and snow to pour in down a chimney ability.
During work, V-type weather shield 5 has guide functions, can reduce flowing resistance.Wind-blocking board 7 swings while ventilating with the wind, and the larger aerofoil of wind-force is more tending towards level, less with the aperture of air outlet 6, naturally regulates rain and snow to pour in down a chimney ability.
Claims (3)
1. a unpowered blast cap, comprise structure stand, in structure stand bilateral symmetry, be provided with arc outer casing, the bottom that is positioned at outer casing in structure stand both sides is provided with ditch, at structure stand two ends, be provided with end plate, structure stand bottom and upper end form respectively air intake and air outlet between the outer casing of both sides, it is characterized in that: in structure stand, middle part is provided with the V-type weather shield that width is greater than air intake and air outlet, the two ends of V-type weather shield are drawn by end plate respectively, on end plate, the corresponding described V-type weather shield place of drawing is provided with outfall, in structure stand upper end, be hinged with the wind-blocking board that air outlet can be closed.
