Abstract

The utility model relates to a curved natural ventilator, which comprises a curved skeleton body which is packed with contour plates to form integration wind cap. The inner of the wind cap is provided with a rain shield roof which is formed by the method that a plurality of layers of trusses are provided with rain shield baffles through a drainage channel on the bottom edge. The ventilating throat opening corresponding to the lower part of the rain shield roof is symmetrically provided with a valve plate used for adjusting and controlling ventilation quantity. The utility model has the advantages of great ventilation, small local resistance, good daylighting, and favorable performance for preventing wind and rain back flow, and is an ideal roof natural ventilation device suitable for industrial enterprises and especially for workshops and workshops of high temperature operation.

Description

The arc natural ventilator

The utility model relates to a kind of ventilation unit, is a kind of roof ventilator specifically.

The used ventilating skylight of existing industrial enterprise workshop factory building, its form has following several substantially: " * " type skylight, middle suspension type rectangular skylight and other formula version skylights, room, this several classes sky is through and mostly is the compartment layout on the factory building, the structure dullness, not capable of being combined, install cumbersomely, and hinder now and look forward or upwards; Simultaneously its air quantity is mostly non-adjustable, and exhaust air rate is restricted, and coefficient of partial resistance is bigger, and weather proof to pour in down a chimney function bad.This class skylight especially under work work, the higher condition of health conditions requiring, is difficult to satisfy the ventilation requirement in the industrial enterprise of modern fairly large and higher class.

The purpose of this utility model is to provide a kind of novel arc natural ventilator at above-mentioned the deficiencies in the prior art part.The shortcoming that it can overcome that existing ventilating skylight exhaust air rate is fixed, resistance coefficient is big, wind and rain pours in down a chimney, satisfy not only easy for installation but also integrate purifications, beautify modern production life requirement, and the function of raising air quality index is arranged.

For achieving the above object, technical solution of the present utility model, realize by following measure: comprise a skeleton structure body, make the coated die mould deep bead of two side ends form whole fan housing, weather proof is installed every the top in fan housing, described weather proof is every the top, be to have on the truss of gradient by several layers weather shield is set respectively, by being communicated with formation along the rhone of installing on the truss of last gutter plate and spacer at the bottom of the weather shield, make on the inwall of delivery port corresponding to deep bead of its rhone low order end, and the drain chamber conducting that forms with the base backplate; Correspondence is symmetrical arranged valve plate and a controlling organization in weather proof on the aditus laryngis that respectively ventilates of bottom, top, in order to regulate the control ventilation.

The utility model is compared with prior art has following advantage:

1, the whole arc combining form that adopts, not only novel structure, appearance uniqueness, good looking appearance, and also ventilation effect is good, and flowing resistance can not produce vortex phenomenon.

2, adopt the multilayer weather proof every the top, it is good that performance is poured in down a chimney in daylighting, weather proof, directly rainwater discharged by drainage arrangement.

3, ventilator has the arc valve plate of symmetry, by from the arbitrary position of the adjustable chain of lock control device, opens and closes flexibly, has the big and adjustable characteristics of exhaust air rate.

Do concrete description in conjunction with the utility model accompanying drawing:

Fig. 1 is an arc natural ventilator topology view.

By shown in Figure 1, the frame body that the skeleton 1 of arc natural ventilator and truss 5 all adopt light section steel structure to be combined into connects to form whole fan housing by the coated color metal die mould of skeleton 1 structure, two arc sides deep bead 6 and base flashing plate.And in fan housing, install to have on the truss 5 of gradient by multilayer weather shield 3 is set respectively, be communicated with the weather proof of formation every the top along the rhone 2 that is provided with on the truss 5 of last catchment gutter plate 7 and every interval one fragment position by 3 ends of weather shield.Rainproof drainage system is to utilize on the inwall of delivery port corresponding to deep bead 6 of rhone 2 low order ends be connected with gutter 7, and with the drain chamber conducting of base flashing sheet separation formation.Valve plate 4 by weather proof symmetrically arranged curved shape on the aditus laryngis that respectively ventilates of the bottom correspondence on top, one end and the ventilation aditus laryngis place of valve plate 4 are connect, the other end is connected with an opening-closing control mechanism, is in any enable possition in order to control valve plate 4 and regulates ventilation.

Opening-closing control mechanism is to be connected and composed by pull rope and arc valve plate 4 one ends by motor, also can adopt manually or other external power.

The truss of installing in the fan housing 5 can be herringbone layering setting, and two side ends is installed weather shield 3 on the truss 5 on upper strata, and the center top end is an aperture, and top closure is installed weather shield 3 on the bottom truss 5, and making it not only can be rainproof but also can guarantee to have good daylighting effect.

Workshop, factory building that arc natural ventilator of the present utility model is particularly suitable for high-temperature operation need use under the condition of gravity-flow ventilation.

Claims
