The specific embodiment
The structural representation of roofing ventilator 10 of the present utility model among Fig. 1.As shown in Figure 1, roofing ventilator 10 comprises:
A turbine head 11, this turbine head 11 comprises upper plate 112 and base ring 113 of several turbine type blades 111, a circle, several turbine type blades 111 are connected between upper plate 112 and the base ring 113 by certain interval and angle, described connection can be passed through rivet, self-tapping screw connects or double nut connects, and preferably adopts double nut to connect; The shape of seeing turbine head 11 from the top as shown in Figure 2.In addition, the two side ends of turbine type blade 111 also is provided with the diversion division (not shown) of " V " type.
A bearing arrangement 12, this bearing arrangement 12 is positioned at the inside of turbine head 11, comprising can a counterrotating sleeve 121 and a turning cylinder 122, and the bearing (not shown) between sleeve 121 and the turning cylinder 122, sleeve 121 is provided with a flange, and therefore, the upper end of sleeve 121 can utilize rivet or tapping screw to be fixed on the central authorities of upper plate 112 by this flange, and the extending axially of turbine head 11, turning cylinder 122 stretches out from the lower end of sleeve 121;
Four connecting rods 13 are connected between the inwall of the sleeve 121 of bearing arrangement 12 and base ring 113, and connection herein can realize by rivet or tapping screw, to prevent turbine head 11 distortion;
A support 14, its center 141 is fixed on the turning cylinder 122 by nut collar, and 141 are extended with four branches 142 from the center;
An angle neck 15, each branch 142 of support 14 all is fixed on the angle neck 15 cylindraceous, angle neck 15 comprises top 151 and the bottom 152 that the angled plane cutting in edge and sagittal plane is opened, upper and lower portion 151,152 link together by " S " type and " C " type connecting portion 153 of junction, thereby can rotate relative to one another, when upper and lower part 151,152 when diverse location cooperates, the end face on top 151 is also different thereupon with the angle of the end face of bottom 152.So in actual applications, rotate the top 151 of angle neck 15, just can adjust the angle of roofing ventilator turbine head 11 sagittal planes,, also can be parallel to ground level on the roofing of inclination even when it is installed with respect to roofing; And
A waterproof substrate 16 is provided with the through hole 161 of a diameter less than the internal diameter of angle neck 15 on waterproof substrate 16, angle neck 15 is located on the through hole 161 and is fixed on the waterproof substrate 16.It is a variety of to realize that angle neck 15 the method on the waterproof substrate 16 of being fixed on has, and present embodiment is that a circle projection 162 is set on through hole 161 peripheries, then angle neck 15 is enclosed within on the projection 162, fixes with rivet or tapping screw.Also can directly angle neck 15 be welded on the waterproof substrate 16, or the like.
If roofing does not tilt, then angle neck 15 can be the middle cylinder of one.
It should be noted that in actual applications, behind the position of adjusting angle neck 15, should be by sheet metal and rivet, for example four sheet metals and eight rivets are fixed together two parts about the angle neck.
In actual applications, should stick the waterproof clay band in the junction of waterproof substrate 16 and roofing; And at angle neck rotating part about in the of 15, and all stamp water-proof silica-gel around all screws, purpose all is that anti-sealing enters ventilator 10 the insides.
Fig. 3 is the stereogram after the roofing ventilator assembling of the present utility model.
Roofing ventilator of the present utility model can be made with materials such as stainless steel, aluminium alloys.
As mentioned above, when natural wind blowed to described turbine head, the turbine type blade was subjected to clockwise moment and rotates, and blade is outwards pushed the air at place, impeller clearance open when rotated, produces inside and outside differential pressure, thereby room air is outwards flowed.In addition, the ascending motion of hot-air when there is the temperature difference in indoor and outdoor, and the differential static pressure of indoor-outdoor air also can cause turbine head to rotate, therefore roofing ventilator of the present utility model can be rotated for a long time, finishes the function of ventilation.
Because the clearance opening of turbine type blade is in the side, and the two side ends of blade is provided with the diversion division of V-type, be used for the inside of anti-sealing from the outer side inflow turbine head of blade, thereby rainwater can not flow in the turbine.The air of the turbine head of rotation discharge has simultaneously also stopped the inflow of rainwater.And roofing ventilator 10 is rotations in 24 hours, therefore can prevent that dust from entering.
In addition, roofing ventilator 10 is utilized is natural wind and electrification does not have noise and energy savings when therefore turning round.
Clearly, though described embodiment of the present utility model in detail, under the situation that does not deviate from spirit and scope of the invention, can make various changes to the utility model, substitute and change at this.Therefore, the utility model is only by content constraints that the appended claims limited.
