Abstract
The utility model relates to a protective mesh enclosure special for a double air-in volute fan and matched with the double air-in volute fan. The middle of an annular mesh enclosure framework is provided with a Y-shaped bearing bracket groove of which the three end parts are provided with positioning holes in the annular mesh enclosure framework, a wire mesh is welded on the back of a gap between the annular mesh enclosure framework and the Y-shaped bearing bracket groove, two semicircle enclosure compensating ports and an L-shaped screw connecting piece compensating port are inwards concave in the edge of the annular mesh enclosure framework corresponding to a groove of the Y-shaped bearing bracket groove, and the annular mesh enclosure framework at the groove of the Y-shaped bearing bracket groove is provided with a wire hole. The protective mesh enclosure special for the double air-in volute fan has the advantages that the wind resistance is maximally reduced, the mounting is facilitated as the structure is matched with the double air-in volute fan, the personal safety is favorably protected, the mesh enclosure strength is high, and the process is easy to realize as the structure is simple.
Description
Technical field
The utility model relates to one can reduce windage to greatest extent, prevents that finger is strayed into the inner two air intake spiral case blower fan protection nets that injury occurs of blower fan, belongs to two air intake spiral case blower fan special protection guards and manufactures field.
Background technique
The two unshielded guards of air intake spiral case blower fan of 133 current types, blower fan port is directly exposed outer spacious, when general mood rotation, between fan blade, easily form air-flow whirlpool, thereby form larger windage, electric energy is produced to direct loss, meanwhile, in the middle of exposed draught fan impeller, be hollow shape, easily cause potential safety hazard.
Model utility content
Purpose of design: for avoiding the deficiency in background technique, design two air intake spiral case blower fan special protection guards of the two air intake spiral case blower fans of a kind of special dispensing 133 types.
Design proposal: for realizing above-mentioned purpose of design.The utility model is in design proposal: 1, in the middle of ring guard skeleton, open Y shape bearing bracket groove, positioning hole is driven in three ends of Y shape bearing bracket groove on ring guard skeleton, steel wire is welded on the back side, space between ring guard skeleton and Y shape bearing bracket groove, the ring guard skeleton edge of Y shape bearing bracket geosynclinal concave groove corresponding part is recessed two semicircle casing compensating ports and a L shaped bolt jointing part compensating port inwardly, on the ring guard skeleton of Y shape bearing bracket groove groove, have the design of wire hole, it is one of technical characteristics of the present utility model.The object of doing is like this: in the middle of ring guard skeleton, open Y shape bearing bracket groove and Y shape bearing bracket can be arranged in Y shape bearing bracket groove, three ends of Y shape bearing bracket groove are driven positioning hole and can two air intake spiral case blower fan protection nets be screwed on two air intake spiral case blower fan mouths in the mode of three points location on ring guard skeleton, the ring guard skeleton edge of Y shape bearing bracket geosynclinal concave groove corresponding part is recessed two semicircle compensating ports and a L shaped compensating port inwardly, two semicircle compensating ports are that the casing projection of the two air intake spiral case blower fans of 133 types is left room, L shaped compensating port is the screw rod of the two air intake spiral case blower fans of 133 types, the assemblies such as the bolt surplus of leaving room, so that client safeguards the two air intake spiral case blower fans of 133 types as required, wire hole is opened on the ring guard skeleton on Y shape bearing bracket geosynclinal concave groove, can reduce electric wire inner length, is convenient to client's use of switching on.2, the mesh wire diameter of steel wire is 0.7 millimeter-1.0 millimeters, and the design that the mesh aperture on steel wire is less than 5 millimeters, is two of technical characteristics of the present utility model.The object of doing is like this: the mesh wire diameter of steel wire is 0.7 millimeter-1.0 millimeters; can under same homalographic, increase air output; intake grill is divided into several little intake grills by the steel wire that is less than 1 millimeter; avoid forming complete air-flow; to reduce the windage of air stream to fan blade formation in the two air intake spiral case blower fans of 133 types; directly reduce energy consumption, the aperture design of 5 millimeters can be avoided damaging because finger in the manual operations such as maintenance puts in guard simultaneously, protection personal safety.
Technological scheme: a kind of two air intake spiral case blower fan special protection guards, in the middle of ring guard skeleton, open Y shape bearing bracket groove, positioning hole is driven in three ends of Y shape bearing bracket groove on ring guard skeleton, steel wire is welded on the back side, space between ring guard skeleton and Y shape bearing bracket groove, the ring guard skeleton edge of Y shape bearing bracket geosynclinal concave groove corresponding part is recessed two semicircle casing compensating ports and a L shaped bolt jointing part compensating port inwardly, on the ring guard skeleton of Y shape bearing bracket groove groove, has wire hole.
The utility model compared with background technique, the one, can reduce to greatest extent windage; The 2nd, its structure matches with two air intake spiral case blower fans, is convenient to install; The 3rd, reasonable protection personal safety; The 4th, guard intensity is strong; The 5th, this is simple in structure, and technique easily realizes.
Brief description of the drawings
Fig. 1 is the main TV structure schematic diagram of two air intake spiral case blower fan special protection guards.
