Abstract

The utility model provides an aluminum aerofoil type leaf angle adjustable cooling air blower. A turntable is fixed on a rotation shaft of a motor; a fan blade is aerofoil-shaped and is a hollow aluminum sectional material; a reinforcing rib is formed in a hollow internal part of the fan blade, and axially extends along the fan blade; a stopper is fixed at the top of the fan blade, and consists of a plug bush post and a fixed lug, which are formed on a crescent board; the plug bush post is inserted inside the hollow part of the fan blade and is fixed with the fan blade through a screw; the fixed lug is adhered to the fan blade in a pressed manner and is fixed with the fan blade together through the screw; a connection piece consists of a shaft part and a fan blade fixing part; an annular groove is formed on the shaft part; a U-shaped screw rod is clamped on the annular groove and is inserted in pre-set holes of a fastening piece and the turntable; the upper part of the U-shaped screw rod is screwed and fixed with a nut; the nut is pressed on the turntable; and the fan blade is fixed at the fan blade fixing part of the connection piece. The aluminum aerofoil type leaf angle adjustable cooling air blower provided by the utility model has the advantages of large cooling area and good cooling effect; and the angle of the fan blade can be randomly adjusted, so that the angle of the fan blade can be adjusted according to different conditions.

Description

Aluminum wing blade leaf angle adjustable cooling machine

Technical field:

The utility model relates to the fan technical field, more specifically to aluminum wing blade leaf angle adjustable cooling machine.

Background technique:

At present, in some large-scale operational sites, use the cooling of common electric fan to have following problem: 1, electric contact such as plug and socket is too many, easily causes potential safety hazard.2, common fan air flow is little, and the wind cooling-down effect of producing by boasting is poor.

The general industrial electric fan mainly is the propeller formula electric fan that adopts big flabellum, this flabellum is the electric fan of type in the shape of a spiral, if exist flabellum to do greatly then requirement of strength problem of higher to material occurs, therefore can't do fan bigger, lower the temperature than large space and allow.

The model utility content:

The purpose of this utility model is exactly the deficiency at prior art, and provide a kind of aluminum wing blade leaf angle adjustable cooling machine, its cooling area is big, good cooling effect, be particularly suitable for integrated mill's manufacturing shop, use during the large stadium cooling, the angle of flabellum can be regulated arbitrarily, can regulate the angle of flabellum according to varying environment.

Technology solution of the present utility model is as follows:

Aluminum wing blade leaf angle adjustable cooling machine, comprise suspension bracket, motor and flabellum, motor is fixed in the suspension bracket, rotating disk is fixedly arranged in the rotating shaft of motor, flabellum is wing shapes, flabellum is the hollow aluminum section bar, form stiffening rib in the flabellum hollow interior, stiffening rib extends axially along flabellum, the retaining plug is fixedly arranged at the top of flabellum, retaining plug by form on the crescent shape plate sleeve post and fixedly ear form, sleeve post sleeve is fixed together in the hollow part of flabellum and by screw and flabellum, fixedly ear is pressed against on the flabellum and by screw and flabellum and is fixed together;

Link is become with the flabellum fixing part by axial region, form annular groove on the axial region, U-shaped screw rod be fastened on the annular groove and sleeve in the default hole of fastening piece and rotating disk, the top of U-shaped screw rod is bolted and fixed with nut, nut is pressed on the rotating disk, and flabellum is by on the flabellum fixing part that is bolted to link.

Form the groove that matches with axial region on the described fastening piece, axial region is fastened on this groove, and groove is semicircle, arc or square.

The beneficial effects of the utility model are:

1, its flabellum is wing shapes and adopts aluminum alloy to be made into hollow shape, the one, can do fan bigger, and the 2nd, flabellum intensity is good, can blow out larger area wind, and flabellum can be worked again lastingly simultaneously, can not damage because of insufficient strength.

2, it can produce similar cool breeze of brushing naturally and blow to the whole production workshop, compares with air-conditioning, more saves electric energy, compares with small-sized fans, and except saving electric energy, cooling and ventilation effect are better.

3, it has avoided the various potential safety hazards of using small fan to produce, the Security that has improved manufacturing shop.

4, the angle of flabellum can be regulated arbitrarily, can regulate the angle of flabellum according to varying environment.
