Abstract
The utility model relates to an unpowered driving exhausting wind ball used in roof-shared exhaust port, which has a shutter-type wind leaf spherical body. A ball top with a shape like an inverted pan bottom is arranged at the top of the sphere. The spherical shutter-type wind leaves are stainless steel leaves. A right-angle erection plate is arranged along the circumferential direction of a bearing base ring vertical to a ring. The wind ball rotates naturally under the function of the updraft in the indoor shared wind passage and the external wind force; the smoke can be discharged from the bevel apertures of the shutter-type leaves. The right-angle erection plate can be directly arranged on the cement cover board at a wind passage outlet; special connectors for fixation and setting are not needed; the setting structure is simple and convenient. The utility model solves the problems of difficult wind ball setting, long setting period and weak setting strength. The stainless steel wind leaves can avoid corrosion caused by harsh weather and prolong the service life of the wind ball. The utility model can prevent rain water pouring into the exhaust port.
Description
Technical field
The utility model relates to and is used for the unpowered driving exhaust of the shared exhaust duct in roof wind ball.
Background technology
The utility model is further improvement and the development to the existing unpowered driving wind of the shared exhaust duct in roof ball.
For the wind and rain that forfends the shared exhaust duct exit opening of dwelling house pours in down a chimney, the air exit of shared air channel, roof or flue all is equipped with the simple and easy blast cap of umbrella shape shape usually, because cap structure is simple and easy, intensity is low, can not bear certain other wind-force of level.A kind of some curved blades of using are arranged in the shared exhaust duct blast cap in known roof, and by the Ball-shape wind exhaust cover that circumferential arrangement is formed, its circular arc vane is combined into the blade structure of venetian blind type around its sphere by certain angle.The blade that its adopts is a thin-walled paint colored steel, and colored steel is with aluminium flake or soft iron plate drawing.The top of the exhaust blast cap that constitutes is flat-top or spill end face.Vanes fixed is connected between flat-top and the annular round platform under it.It needs to do a special connector in the process that connects the air channel, roof.The mounting structure complexity requires height, and is cumbersome, time-consuming, and insecure.The junction is subjected to typhoon influence, and is fragile.Used blade blast cap easily gets rusty under the tired wind and rain of day day of year is attacked, and the life-span is short, must change in 1 year.
Summary of the invention
The utility model purpose is that design a kind ofly is difficult for getting rusty, life-span length, sound construction, need not by connector the unpowered driving exhaust wind ball that also can effectively prevent seeking shelter from wind and rain and pour in down a chimney to be installed.
The technical scheme in the invention for solving the technical problem is: be used for the unpowered driving exhaust of the shared exhaust duct in roof wind ball, has one by certain angle and around its sphere arrangement, the fan blade spherical surface body that is venetian blind type, special character of the present utility model is, the top of sphere is a seamless ball top that is reverse pan bottom shape, the stainless steel blade that constitutes sphere venetian blind type fan blade is connected between the annulus of the annular disk that is the reverse pan bottom shape outer rim and bottom bearings, and the bearing block annulus circumferentially is equipped with circumferentially and the square installation steel plate of vertical its annulus.
Each leaf blade both sides of the present utility model can be shaped on the direction groove.
The utility model compared with prior art has following beneficial effect.
The utility model has adopted leaf blade has been connected between the outer ring or the inner ring face of cylinder of the annular disk that is reverse pan bottom shape and bearing.Guaranteed that the wind ball in the ascending air in indoor shared air channel and the rotation naturally under the external wind effect, can discharge flue gas from the slit, oblique angle of louvered blade.The circumferentially uniform several squares in endless belt that extend the bearing cylinder from bearing inner race or outer ring are installed steel plates and can directly be mounted on the cement plate cover plate of ducting outlet, need not the special connector fixed installation, and mounting structure is simple and direct, and is convenient.Solved the wind ball difficulty is installed, the set-up time is long, the problem that installation strength is not enough.Wind ball after the installation is not worried the attack of typhoon.The stainless steel leaf blade that adopts, the corrosion of avoided wind and frost sleet, exposing to the sun and rain has prolonged service life of wind ball.Become the top of reverse pan bottom shape can not corrode the wind ball by ponding.The direction groove of fan blade both sides designs can prevent from that rainwater from pouring in down a chimney to enter discharge duct.
Description of drawings
Following accompanying drawing has been described an embodiment of the present utility model.
Fig. 1 is a forward structure schematic diagram of the present utility model.
Fig. 2 is of the present utility model bowing to ball top schematic diagram.
The unpowered driving exhaust of the shared exhaust duct in the roof wind ball that leaf blade by the stainless steel drawing assemblies has been described in Fig. 1, Fig. 2.The oblique angle sphere shape leaf blade 1 that wherein adopts the drawing of stainless steel sheet material is shaped on crimping reinforcement 2 with the form of prior art at edge, the left and right sides.The bottom of blade is fixed on bottom end bearing 13 by screw 3 or rivet, on the upwardly extending endless belt of the anchor ring of outer ring or inner ring.The top of blade is fixed on by screw or rivet 12 and is positioned on the annular disk 9 that wind ball top is reverse pan bottom shape outer rim 11.Dish-shaped terminal pad 10 is arranged on the central term of wind ball, fixed by trip bolt, terminal pad is mainly used in coining trademark and label.The both sides design of blade has deflection 7,8.Being positioned on the same circumference four installs steel plate 5 from the outwardly directed square of bearing 13 inner rings or outer ring and is fixed on the endless belt 6 that bearing outer ring or inner ring extend downwards by screw.The inner chamber of wind ball is equipped with triangle fixed support (not shown) with the form of prior art.
Above-mentionedly only listed specific embodiments more of the present utility model, to one skilled in the art, the modification of under the situation that does not exceed claim institute restricted portion, the utility model being made or revise should be at the row of protection of the present utility model.
Claims (2)
1. the unpowered driving exhaust of the shared exhaust duct in roof wind ball, has one by certain angle and around its sphere arrangement, the fan blade spherical surface body that is venetian blind type, it is characterized in that: the top of sphere is a seamless ball top that is reverse pan bottom shape, the stainless steel blade that constitutes sphere venetian blind type fan blade is connected between the annulus of the annular disk that is the reverse pan bottom shape outer rim and bottom bearings, and the bearing block annulus circumferentially is equipped with circumferentially and the square installation steel plate of vertical its annulus.
