Abstract
The utility model relates to technical field of energy equipment, especially a kind of low-resistance cowling.It comprises cover body, capouch and flexible rod, and capouch is connected to the front end of cover body by flexible rod, and capouch is provided with apron, and flexible rod is set with spring.Cover body is connected by flexible rod the capouch of taper, and respectively spring and apron is set on flexible rod and capouch.During use, gas shock capouch, a part enters the guiding gutter on capouch surface, flows along guiding gutter, be converted into the driving force that capouch rotates, another part flows to apron along the surface of capouch, and extruding apron shrinks, and is converted into the pressure of apron, some compresses flexible rod, change into the crumple power of spring, thus alleviate the pressure of air-flow to pant main bodies, greatly reduce windage.
Description
Technical field
The utility model relates to technical field of energy equipment, especially a kind of low-resistance cowling.
Background technique
Along with the fast development of Wind Power Utilization in world wide, the design of wind power generating set is tending towards maximization, variation, and equally, the design of engine room cover also will inevitably to maximization, diversified future development.At present, although the cowling of wind-driven generator front end is all rounded shape, structure is single, and resistance is larger.
Model utility content
Single in order to overcome existing dome structure, the deficiency that resistance is larger, the utility model provides a kind of low-resistance cowling.
The utility model solves the technological scheme that its technical problem adopts: the utility model solves the technological scheme that its technical problem adopts and is: a kind of low-resistance cowling, comprise cover body, capouch and flexible rod, capouch is connected to the front end of cover body by flexible rod, capouch is provided with apron, and flexible rod is set with spring.
According to another embodiment of the present utility model, comprise capouch further tapered, be rotatably connected in the front end of flexible rod.
According to another embodiment of the present utility model, the outer surface comprising capouch is further evenly distributed with spiral guiding gutter.
According to another embodiment of the present utility model, comprising apron is further elastomeric plastics plate, is centered around the afterbody of capouch.
According to another embodiment of the present utility model, comprise spring clip further between cover body and capouch.
The beneficial effects of the utility model are, cover body is connected by flexible rod the capouch of taper, and on flexible rod and capouch, arranges spring and apron respectively.During use, gas shock capouch, a part enters the guiding gutter on capouch surface, flows along guiding gutter, be converted into the driving force that capouch rotates, another part flows to apron along the surface of capouch, and extruding apron shrinks, and is converted into the pressure of apron, some compresses flexible rod, change into the crumple power of spring, thus alleviate the pressure of air-flow to pant main bodies, greatly reduce windage.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. cover bodies, 2. capouch, 3. flexible rod, 4. apron, 5. spring, 6. guiding gutter in figure.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of low-resistance cowling, comprise cover body 1, capouch 2 and flexible rod 3, capouch 2 is connected to the front end of cover body 1 by flexible rod 3, and capouch 2 is provided with apron 4, flexible rod 3 is set with spring 5.Capouch 2 is tapered, is rotatably connected in the front end of flexible rod 3.The outer surface of capouch 2 is evenly distributed with spiral guiding gutter 6.Apron 4 is elastomeric plastics plate, is centered around the afterbody of capouch 2.Spring 5 is stuck between cover body 1 and capouch 2.
Cover body 1 is connected by flexible rod 3 capouch 2 of taper, and respectively spring 5 and apron 4 is set on flexible rod 3 and capouch 4.During use, gas shock capouch 2, a part enters the guiding gutter 6 on capouch 2 surface, flows along guiding gutter 6, be converted into the driving force that capouch 2 rotates, another part flows to apron 4 along the surface of capouch 2, and extruding apron 4 shrinks, and is converted into the pressure of apron 4, some compresses flexible rod 3, change into the crumple power of spring 5, thus alleviate the pressure of air-flow to pant main bodies, greatly reduce windage.
