In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only It is some embodiments described in this utility model, for those of ordinary skill in the art, is not paying creative work On the premise of, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the schematic perspective view of unpowered eccentric contract one detailed description of the invention of the present utility model;
Fig. 2 is the schematic perspective view of unpowered eccentric contract one detailed description of the invention of the present utility model.
Detailed description of the invention
This utility model is described in detail by each embodiment shown in below in conjunction with the accompanying drawings, but it should explanation, These embodiments are not limitation of the utility model, and those of ordinary skill in the art are according to these embodiment institute works Equivalent transformation in energy, method or structure or replacement, within belonging to protection domain of the present utility model.
As shown in Figure 1, 2, unpowered eccentric contract of the present utility model includes: wind blade 10, centrifugal impeller 20, lead Stream cover 30, adjustable type base 40.
Described wind blade 10, under the drive of wind-force, can rotate, thus drives centrifugal impeller 20 to carry out synchronizing fortune Dynamic.Specifically, described wind blade 10 is positioned at the top of the end face of described kuppe 30, meanwhile, described wind blade 10 and institute State centrifugal impeller 20 to be in transmission connection.Wherein, described wind blade 10 is several, and several wind blades 10 are by connecting rod 11 Being connected with connecting shaft 12, described connecting shaft 12 is in transmission connection with described centrifugal impeller 20.Thus, under wind-force effect, some Wind blade 10 rotates, and drives centrifugal impeller 20 to rotate by connecting shaft 12.
Further, in above-mentioned embodiment, in the connecting rod 11 of several wind blades 10 described is generally aligned in the same plane, Having angle between adjacent connecting rod 11, each angle that some connecting rods 11 are formed is equal.Additionally, for the ease of connecting shaft 12 Rotating, the end face of described kuppe 30 is provided with the bearing block 32 being stretched on described end face, described connecting shaft 12 stretches into described Being in transmission connection with described centrifugal impeller 20 in bearing block 32, described connecting shaft 12 is provided with bearing, described bearing is positioned at described Between bearing block and connecting shaft 12, to assist the rotation of connecting rod 11.
Described centrifugal impeller 20, for when rotated, produces negative pressure, thus is sucked by room air.Specifically, described from Lobus cardiacus wheel 20 is installed in the internal diversion space of described kuppe 30.Meanwhile, described centrifugal impeller 20 is positioned at described adjustable type The top of base 40, and motion can be pivoted by the most described adjustable type base 40.
Described kuppe 30 is for the circulation of secondary air.Specifically, the bottom of described kuppe 30 has air outlet 31, Described kuppe 30 passes through described air outlet 31 and is connected externally to lead to.Thus, the room air being inhaled into can bottom air outlet 31 discharge.Meanwhile, by air outlet 31 is arranged on the bottom of kuppe 30, time the most calm, the circulation naturally of air is prevented again Stop pouring in down a chimney of wind and sleet.
Further, described kuppe 30 is the bore diameter more than described end face of described air outlet 31, described water conservancy diversion The most described end face of sidewall of cover 30 is inclined plane.Being arranged such, air outlet 31 is a tubaeform mouth.Meanwhile, described adjustable type It is attached by dowel between the inwall of base 40 and described kuppe 30.
Described adjustable type base 40 is fixed for the installation realizing unpowered eccentric contract, and can as required, to peace Dress angle is adjusted.Specifically, the described through setting of adjustable type base 40, thus room air is from described adjustable type base 40 Internal cavity sucks.Described adjustable type base 40 includes upper bed-plate 41 and lower bottom base 42, described upper bed-plate 41 and lower bottom base 42 Between there is cooperation face, and described upper bed-plate 41 can rotate along described cooperation face relative to described lower bottom base 42, described cooperation The end face of the most described upper bed-plate in face 41 and the bottom surface of lower bottom base 42 are inclined plane.
So, when upper bed-plate 41 rotates relative to lower bottom base 42, owing to cooperation face therebetween is inclined-plane, along with rotation Carrying out, the wind blade 10 of top, centrifugal impeller 20, kuppe 30 gradually tilt, thus realize the regulation of setting angle.This Outward, the bottom surface of described lower bottom base 42 forms installed surface 420, can be realized the peace of unpowered eccentric contract by this installed surface 420 Dress is fixing.
In sum, unpowered eccentric contract of the present utility model has that design science is reasonable, operational efficiency is high, manufactures Simply, structure is reliable, good looking appearance, the advantage of energy-conserving and environment-protective, and it is making full use of while wind energy carries out indoor exhaust wind, it is possible to Prevent wind, rain, snow from pouring in down a chimney in air outlet, it is ensured that the stability that unpowered eccentric contract runs.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new Type.Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting Involved claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should Description can also be formed those skilled in the art through appropriately combined as an entirety, the technical scheme in each embodiment May be appreciated other embodiments.
