Abstract
The utility model relates to a 120 type double inlet air volute fan protecting mesh cover structure matched with a 120 type double inlet air volute fan. Three support grooves are recessed in a ring-shaped mesh cover framework at equal angles, an L-shaped compensation port is recessed in the ring-shaped mesh cover framework between the two support grooves, a steel wire mesh is welded to the back of the ring-shaped mesh cover framework, and three locating holes are formed in the edge of the ring-shaped mesh cover framework in an equally divided mode. The protecting mesh cover structure has the advantages that air resistance can be reduced to the largest extent; the protecting mesh cover structure is matched with the double inlet air volute fan and is convenient to install; the protecting mesh cover structure is favorable for protecting personal safety; the mesh cover is high in strength; the mesh cover is simple in structure, and a process is easy to achieve.
Description
Technical field
The utility model relates to the two air intake spiral case blower fan protection nets of 120 types of the two air intake spiral case blower fans of a kind of cooperation 120 types, can reduce to greatest extent windage, prevent that finger is strayed into blower fan inside and injures, belong to the two air intake spiral case blower fan protection nets of 120 types and manufacture field.
Background technique
The two unshielded net cover structures of air intake spiral case blower fan of 120 current types, blower fan port is directly exposed outer spacious, during general mood rotation, between fan blade, easily form air-flow whirlpool, thereby form larger windage, electric energy is produced to direct loss, simultaneously, 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 the two air intake spiral case blower fan special protection guards of 120 types of the two air intake spiral case blower fans of a kind of special dispensing 120 types.
Design proposal: for realizing above-mentioned purpose of design.The utility model is in design proposal: 1, ring guard skeleton is with three bracket grooves of equal angles indent, wherein between two locating slots on ring guard skeleton the L shaped compensating port of indent, steel wire is welded on the ring guard skeleton back side, three positioning holes, to wait separately design on the limit of ring guard skeleton, are one of technical characteristicss of the present utility model.The object of doing is like this: at ring guard skeleton, with three bracket grooves of equal angles indent and the two air intake spiral case fan casings of 120 types, match, three bracket grooves are convenient to Y shape bearing bracket seat and are fixed on the two air intake spiral case fan casings of 120 types, on ring guard skeleton, the L shaped compensating port of indent is for the assemblies such as the screw rod of the two air intake spiral case blower fans of 120 types, the bolt surplus of leaving room, so that client safeguards the two air intake spiral case blower fans of 120 types as required.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; the steel wire that is less than 1 millimeter is divided into several little intake grills by intake grill; 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 120 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 pair of air intake spiral case blower fan special protection net cover structure, ring guard skeleton is with three bracket grooves of equal angles indent, wherein between two bracket grooves on ring guard skeleton the L shaped compensating port of indent, steel wire is welded on the ring guard skeleton back side, and three positioning holes are to wait separately on ring guard skeleton limit.
The utility model is compared with background technique, and 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.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the two air intake spiral case blower fan protection nets of 120 types.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of pair of air intake spiral case blower fan special protection net cover structure, ring guard skeleton 1 is with three bracket grooves 2 of equal angles indent, wherein between two bracket grooves 2 on ring guard skeleton 1 the L shaped compensating port 3 of indent, steel wire 4 is welded on ring guard skeleton 1 back side, and three positioning holes 5 are to wait separately on ring guard skeleton 1 limit.The Y shape bearing bracket seat of the two air intake spiral case blower fans of described three bracket grooves 2 and 120 types matches.The mesh wire diameter of described steel wire 4 is 0.7 millimeter-1.0 millimeters, and the mesh aperture of steel wire 4 is less than 5 millimeters.
Embodiment 2: on embodiment 1 basis, the mesh wire diameter preferred value of described steel wire 3 is 1.0 millimeters, or 0.9 millimeter, or 0.8 millimeter, or 0.7 millimeter.
Embodiment 3: on embodiment 1 basis, after described steel wire 3 welds with ring guard skeleton 1, top layer is done plastic-blasting and processed.
Embodiment 4: on embodiment 1 basis, the mesh on described steel wire 3 can be rhombus, or rectangle, or circular, or oval.
It is to be understood that: although above-described embodiment is to the utility model detailed text description of contrasting; but these text descriptions; just the simple literary composition of the utility model mentality of designing is described; rather than the restriction to the utility model mentality of designing; any group, increase or modification that does not exceed the utility model mentality of designing, all falls in protection domain of the present utility model.
