Relative to prior art, the utility model has following advantage:
(1) locomotive cooling fan described in the utility model, be composite structure by making flabellum, and the structural rigidity of flabellum is increased by burying blade root skeleton underground, and this composite layer can be made up of multi-layer fiber cloth and the resin glue for boning between fibre cloth, only have blade root skeleton and wheel hub to adopt metallic material thus in this fan, thus can save the cost of material of fan.The flabellum that fibre cloth and resin glue are made, only need manually paste adding, normal temperature cure man-hour, and blade root skeleton and wheel hub also only need conventional machining, thus also can cut down finished cost.Because this fan is in working process, only need the mould of single flabellum can complete the making of multiple flabellum, the monolithic mold size comparing existing casting aluminium material fan reduces greatly, can reduce the cost of mould.And by the material behavior of resin glue self, flabellum can be made to have good corrosion resistance, and the combination of fibre cloth, resin glue and blade root skeleton also makes the weight of flabellum greatly reduce compared to aluminum casting, is convenient to the installation and maintenance of fan.Simultaneously, utilize the curing characteristics of resin material and the mobility before solidifying, and the pliability of fibre cloth, when flabellum is shaping, also can according to requirements such as product service condition and ambient temperatures, at room temperature produce the flabellum of profile complexity, thus ensure the designing requirement of flabellum, improve the overall performance of fan.
(2) wheel hub is arranged the installation that mounting plate can be convenient to flabellum, use the scaffold of " U " shape that flabellum is installed, the angular adjustment after flabellum installation can be convenient to.
(3) petiole is arranged groove is installed petiole can be made fixing more firm on mounting plate, be moved after installing to prevent flabellum.
(4) accurate adjustment that indicating arrow and graduation line can be conducive to fan blade angles is set, and easy-to-operat.
(5) blade root skeleton exterior edge face arranges lug boss, and the edge of blade root skeleton arrange that kink can make fibre cloth be connected with blade root skeleton more tight.
(6) sprayed plastic coat or wheel hub and petiole are set and carry out zinc-plated process, blade surface spraying gel coat, flabellum outer surface can be made smoothly bright and clean, improve its airmechanics performance and promote the antiseptic property of fan.

Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Embodiment one
The present embodiment relates to a kind of locomotive cooling fan, for the heat radiation of the upper equipment of locomotive (as train), as shown in fig. 1, this locomotive cooling fan is included in the wheel hub 2 that rotating shaft is installed, and the multiple flabellums 1 be connected on wheel hub 2 outer circumferential face, flabellum 1 comprises flabellum body 10, and be located at flabellum body 10 one end, petiole 11 for being connected between flabellum 1 with wheel hub 2.
In the present embodiment, flabellum 1 can be two of being evenly connected on wheel hub 2, three or other quantity.As shown in Figure 2, flabellum body 10 wherein comprises composite layer 13 to the structure of flabellum 1, and is embedded in the blade root skeleton 12 in composite layer 13.Composite layer 13 is comprise the multi-layer fiber cloth that is stacked and placed on together and the resin glue for boning between fibre cloth.In the concrete working process of flabellum 1, be first embedded in fibre cloth by blade root skeleton 12, fibre cloth can adopt glass fibre or carbon fiber, and then resin glue is placed in the enterprising pedestrian's work of fibre cloth and pastes.
