Description

High-efficiency air guide device

Technical Field

The utility model belongs to the technical field of the wind wheel technique and specifically relates to a high-efficient air ducting is related to.

Background

In the field of electric power and energy science, a wind wheel refers to a wind turbine component for converting wind energy into mechanical energy. Consists of a blade and a hub.

Wind wheels are various, but can be classified into two types: the rotating shaft of the wind wheel is parallel to the wind direction; the vertical axis wind wheel has a rotation axis perpendicular to the ground or the airflow direction. The vertical axis wind wheel rotating by using resistance has several types, wherein the wind wheel made of flat plates and quilts is used, and the wind wheel is a pure resistance device; the S-shaped wind wheel has partial lift force, but is mainly a resistance device, and is a main competitor of the horizontal axis wind wheel. Other types of vertical axis wind wheels include magnus effect wind wheels and the like.

The existing wind wheel, especially the horizontal axis wind wheel, mainly has the main functions of centrifugal air exhaust and air exhaust, air intake at the front end face of the wind wheel and then exhaust from the side face of the wind wheel; there are two problems: firstly, the air exhaust amount is insufficient; secondly, the noise is larger.

Disclosure of Invention

In view of the above, it is desirable to provide an efficient air guiding device with low noise and large air discharging amount.

In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a high-efficient air ducting, includes outer wind wheel and interior wind wheel, outer wind wheel includes back shroud and a plurality of outer blade, outer blade is the annular and evenly fixes on the terminal surface before the back shroud, interior wind wheel runs through and fixes in back shroud center department, interior wind wheel includes wheel hub and shaft, the shaft rotates and connects in wheel hub, the epaxial equipartition of shaft has a plurality of to follow axial heliciform inner blade.

Furthermore, the outer diameter of the inner blade is smaller than the inner diameter of the ring formed by the outer blades.

Furthermore, the rear end face of the rear cover plate is in a horn shape with a small front part and a large rear part.

Further, the front end of the inner blade is lower than the front end of the outer blade.

Further, the outer wind wheel further comprises a fixing ring fixed on the front end part of the outer blade.

Furthermore, the outer blades are flat plate curve backward blades.

Further, the hub is provided with a bell mouth which is butted with the rear end face of the rear cover plate.

Compared with the prior art, the utility model discloses following beneficial effect has: this device installs an interior wind wheel additional through the apron center at current semi-open wind wheel to make outer wind wheel have more an air-out passageway, also reduced the noise of original wind wheel, increased the volume of airing exhaust, simple structure, low in production cost.

In order to make the aforementioned and other objects, features and advantages of the invention more comprehensible, preferred embodiments accompanied with figures are described in detail below.

Drawings

Fig. 1 is a schematic structural diagram of the front side of the embodiment of the present invention.

Fig. 2 is a schematic structural diagram of the back side of the embodiment of the present invention.

In the figure: 1-outer wind wheel, 11-rear cover plate, 12-outer blade, 13-fixed ring, 2-inner wind wheel, 21-wheel shaft, 22-inner blade and 23-wheel hub.

Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

As shown in fig. 1-2, a high-efficiency wind guiding device comprises an outer wind wheel 1 and an inner wind wheel 2.

The outer wind wheel 1 comprises a rear cover plate 11, a fixing ring 13 and a plurality of outer blades 12, the outer blades 12 are uniformly fixed on the front end face of the rear cover plate 11 in an annular mode, and the fixing ring 13 is fixed on the front end portion of the outer blades 12. Wind enters from the front end of the outer wind wheel 1, is driven by the outer blades 12 and then is discharged from the peripheral side of the outer wind wheel 1.

The inner wind wheel 2 is fixed at the center of the rear cover plate 11, the inner wind wheel 2 comprises a hub 23 and a wheel shaft 21, the wheel shaft 21 is rotatably connected in the hub 23, and a plurality of spiral inner blades 22 along the axial direction are uniformly distributed on the wheel shaft 21. The wheel shaft 21 of the inner wind wheel 2 discharges the wind along the axial direction, so that the rear end surface of the outer wind wheel also forms an air outlet channel.

In this embodiment, the outer diameter of the inner blade 22 is smaller than the inner diameter of the ring formed by the outer blade 12.

In this embodiment, the rear end surface of the rear cover plate 11 is in a horn shape with a small front and a large rear, so as to guide wind.

In this embodiment, the front end of the inner blade is lower than the front end of the outer blade.

In this embodiment, the outer blades 12 are flat curved aft blades.

In this embodiment, the hub has a bell mouth in butt joint with the rear end face of the rear cover plate, so as to guide wind.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed by the preferred embodiment, it is not limited to the present invention, and any person skilled in the art can make modifications or changes equivalent to the equivalent embodiments by utilizing the above disclosed technical contents without departing from the technical scope of the present invention, but all the modifications, changes and changes of the technical spirit of the present invention made to the above embodiments are also within the scope of the technical solution of the present invention.
