Abstract
The utility model discloses a downslope type natural ventilator and relates to a roof ventilation device. The downslope type natural ventilator comprises a ventilator framework, wherein the ventilator framework is composed of steel brackets through welding and threaded connection. An outer protection plate is arranged outside the ventilator framework. A rainproof plate is arranged inside the ventilator framework. The rainproof plate is horizontally arranged. A flow guide plate is arranged above each end of the rainproof plate. Two oblique beams are arranged in the position, close to the two ends of the rainproof plate, of the ventilator framework. The two oblique beams are arranged in an inverted V shape. The flow guide plate is fixedly connected with the oblique beams. A lower beam is horizontally arranged in the lower portion inside the ventilator framework. Two valve plates are respectively hinged in the middle of the lower beam. Supporting rods are arranged at one ends, far from the hinged position, of the valve plates. Glass reinforced plastic erosion resistant coatings are arranged on the surfaces of the valve plates. Ventilation area inside the downslope type natural ventilator is large, the ventilation efficiency is high, and the practicability is good.
Description
Technical field
The utility model relates to a kind of roof ventilation device, relates in particular to a kind of along sloping formula natural ventilator.
Background technology
Between large car now and need carry out the large-scale smelting shop of air exchange, often need to install roof ventilator, utilize the temperature difference, discharge overfire air within doors outdoor, roof ventilator makes overfire air within doors pass through the nature wind action from discharging within doors, need not personnel operation, and need not electric power energy in 24 hours.But some defective of the structural design of prior roofs ventilator, the flashing board of prior roofs ventilator all is chevron shaped structure, has taken most of area of roof ventilator inner chamber, causes the draught area of ventilator inside little, ventilation efficient is low.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of suitable sloping formula natural ventilator, and its inner draught area is big, and ventilation efficient height is very practical.
The technical solution of the utility model is: a kind of along sloping formula natural ventilator, comprise the ventilator skeleton, described ventilator skeleton is made of by welding and being threaded steel bracket, the ventilator skeleton is outside equipped with outer casing, ventilator skeleton inside is provided with flashing board, described flashing board is horizontally disposed with, top, flashing board two ends is respectively arranged with deflector, the inner position near the flashing board two ends of ventilator skeleton is provided with two inclined beams, two inclined beams are " eight " font and distribute, and deflector is fixedly connected on the inclined beams; The inner lower horizontal of ventilator skeleton is provided with sill, and two valve plates are articulated in the sill middle part respectively, and valve plate is provided with support bar away from an end of hinged place, and the valve plate surface is provided with the fiberglass anticorrosive coat.
As preferably, ventilator skeleton inner and upper has been horizontally disposed with entablature, and flashing board is fixedly connected on the entablature.
As preferably, described steel bracket adopts stainless steel to make.
As preferably, flashing board two ends and ventilator skeleton lower end are respectively arranged with the flashing plate.
The beneficial effects of the utility model are: flashing board of the present utility model is horizontally disposed with, and has increased the draught area of ventilator inside.Deflector can improve the ventilation efficient of ventilator.The flashing plate makes water resistance of the present utility model better, fiberglass is good anticorrosive material, atmosphere, water and multiple acid, alkali, salt and multiple organic solvent all there is good resistivity, prolonged service life of the present utility model, and it only needs at corresponding component external coating fiberglass, manufacture craft is simple, and is very practical.
Description of drawings
Fig. 1 is an internal structure schematic diagram of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of along sloping formula natural ventilator, comprise ventilator skeleton 1, described ventilator skeleton 1 is made of by welding and being threaded steel bracket, in the present embodiment, as preferably, described steel bracket adopts stainless steel to make.Ventilator skeleton 1 is outside equipped with outer casing 2, and ventilator skeleton 1 inside is provided with flashing board 3, and described flashing board 3 is horizontally disposed with, in the present embodiment, as preferably, ventilator skeleton 1 inner and upper has been horizontally disposed with entablature 7, and flashing board 3 is fixedly connected on the entablature 7.
Top, flashing board 3 two ends is respectively arranged with deflector 4, ventilator skeleton 1 inner position near flashing board 3 two ends is provided with two inclined beams 6, two inclined beams 6 are " eight " font and distribute, and in the present embodiment, inclined beams 6 is fixedly connected on the crossbeam 7 by support bar.Deflector 4 is fixedly connected on the inclined beams 6.Ventilator skeleton 1 inner lower horizontal is provided with sill, and two valve plates 9 are articulated in the sill middle part respectively, and valve plate 9 is provided with support bar 8 away from an end of hinged place.Can control the angle that valve plate 9 is opened by support bar 8, in order to adjust ventilation.In the present embodiment, as preferably, flashing board 3 two ends and ventilator skeleton 1 lower end are respectively arranged with flashing plate 5.Valve plate 9 surfaces are provided with the fiberglass anticorrosive coat, have prolonged service life of the present utility model, and are very practical.
The above only is a kind of embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and obvious mode of texturing etc., all should be included within the protection domain of the present utility model.
