Abstract
The utility model discloses a cast iron fan cover, two annular groove holes with openings outwards and cross sections square are formed in the outer wall of a top cover, a bottom cover having a same axis as the top cover is arranged under the top cover, two annular groove holes with openings outwards and cross sections square are formed in the outer wall of the bottom cover, the top cover and the bottom cover are same in thickness, vertical spokes are arranged between the top cover and the bottom cover, a channel piece is arranged between two of the spokes, and a lug plate folded outwards is arranged on the periphery of an opening in the outer side of the channel piece. Compared with the prior art, the cast iron fan cover has the advantages of being strong in performance, good in application effect, long in service life, high in material using efficiency, simple in structure and technique, flexible in layout and the like.
Description
Technical fieldThe utility model relates to a kind of parts of generator, relates in particular to a kind of fan guard.
Background techniqueWind-driven generator is that equipment is very widely used in fields such as water conservancy, heating, refrigeration, shipping and generating, fan guard is one of important components on the wind-driven generator, and itself and fan coupling are used, and are installed in the top of blower tray, existing cast iron fan guard is because the defective on its structure and the processing mode, make its not only poor performance, effect is undesirable, is not easy to install and transportation, and process loaded down with trivial details, the material utilization rate is low, the cost height, and working life is short.
Summary of the inventionThe purpose of this utility model is to provide a kind of not only self performance strong, and effect is good, long service life, and stock utilization height, and structure, technology are simple, layout is flexible, processes easyly, and fabricating cost is low, alleviates the cast iron fan guard of labor strength.
The utility model comprises top cover, end cover, spoke, channel part and otic placode, and wherein the top cover is annular body, and it is square annular slotted hole I that the outer wall of described top cover is offered the outside and cross section of at least two openings; Be provided with the end cover coaxial with it under the top cover, this end cover is and the identical annular body of top cover diameter, the outer wall of cover of the described end offer at least two openings outwards and the cross section be square annular slotted hole II; The thickness of described top cover and end cover is identical and be provided with several vertical spokes between them, the thickness of these spokes overlaps identical with the top and is distributed on and pushes up between cover and the end cover, the end top, lower end of the top of each spoke and described top cover links together, and the top, upper end of the bottom of every spoke and described top cover links together; Be provided with channel part between two spokes therein, this channel part is that equal opening in two ends and cross section are square housing, end top, lower end of the top of side opening and above-mentioned top cover links together in it, the bottom of side opening links together with the end top, upper end of cover of the above-mentioned end in the channel part, and the both sides of the interior side opening of channel part link together with the spoke of its both sides respectively; Be provided with the otic placode that turns up around the outer openings of above-mentioned channel part.
The utility model be by raw metals such as iron and titanium, silicon, manganese directly casting form, wall thickness can reach about 8mm, not only wall is thin, and in light weight; The top of the present utility model cover and the end put all establishes annular slotted hole, has so not only improved working efficiency, has saved material, avoids the accumulation of surface etching thing, and is convenient to transportation, saving cost.
The utility model compared with prior art also has following advantage:
1, self performance is strong, and effect is good, long service life, stock utilization height;
2, structure, technology are simple, and layout is flexible, process easyly, and fabricating cost is low, alleviates labor strength.
Description of drawingsFig. 1 looks generalized section for master of the present utility model.
EmbodimentIn the schematic representation of cast iron fan guard shown in Figure 1, top cover 1 be annular body, and it is square annular slotted hole 2 that the outer wall of described top cover is offered the outside and cross section of two openings; Be provided with the end cover 3 coaxial with it under the top cover, this end cover is and the identical annular body of top cover diameter, the outer wall of cover of the described end offer two openings outwards and the cross section be square annular slotted hole 4; The thickness of described top cover and end cover is identical and be provided with several vertical spokes 5 between them, the thickness of these spokes overlaps identical with the top and is distributed on and pushes up between cover and the end cover, the end top, lower end of the top of each spoke and described top cover links together, and the top, upper end of the bottom of every spoke and described top cover links together; Be provided with channel part 6 between two spokes therein, this channel part is that equal opening in two ends and cross section are square housing, end top, lower end of the top of side opening and above-mentioned top cover links together in it, the bottom of side opening links together with the end top, upper end of cover of the above-mentioned end in the channel part, and the both sides of the interior side opening of channel part link together with the spoke of its both sides respectively; Be provided with the otic placode 7 that turns up around the outer openings of above-mentioned channel part.
