Abstract
The utility model discloses a wind-driven generator, particularly a wind-driven generator group streamline trapezium engine room cover composed of an upper engine room cover and a lower engine room cover. The engine room covers are fixed into a whole by a bolt. The back end of the lower engine room cover is big and the front end of which is small. The whole external shape is streamline trapezium. An included angle between the bottom face and the horizontal surface of the lower engine room cover is 10-30 degrees. Therefore, the structure facilitates ventilation, heat radiation of the electric generator and the wind direction regulation, decreases the resistance and enhances the wind direction capturing sensitivity.
Description
Technical field
The utility model relates to a kind of wind-driven generator, relates to the trapezoidal engine room cover of a kind of wind power generating set streamline specifically, belongs to technical field of wind power generating equipment.
Background technique
Wind-driven generator is positioned at the cabin work that outdoor high-altitude is less and seal, and ventilation condition is relatively poor, and the heat of cabin inner accumulated is difficult for coming out comparatively fastly and unobstructedly.The sun directly shines the cabin, and cabin air temperature is raise, though motor adopts forced air cooling, but the shell heat radiation that can only lean on generator makes the machine operation environment become abominable.The engine room cover of wind power generating set normally adopts configuration design as depicted in figs. 1 and 2, and its makings is simple and convenient, and be easy to fitting operation, but still have deficiency on the form structure, i.e. improper ventilation, radiating effect is relatively poor, and is strong inadequately to wind direction sensitivity seizure.
The model utility content
The utility model provides a kind of wind power generating set streamline trapezoidal engine room cover in order to solve the problems of the technologies described above exactly, and this engine room cover is convenient to ventilate in the engine room cover, helps the generator heat radiation, is convenient to the wind direction adjustment, improves wind direction and catches sensitivity.
In order to solve the problems of the technologies described above, the utility model is achieved by the following technical solution.
The trapezoidal engine room cover of wind power generating set streamline, it is to be made of top engine room cover, bottom engine room cover two-part, two-part engine room cover is connected to integral body by bolt, the big front end in engine room cover rear end, bottom is less, it is trapezoidal that overall appearance is shaped as streamline, and the bottom surface of bottom engine room cover becomes 10-30 ° of angle with horizontal plane.
Described top engine room cover and bottom engine room cover are bolted to connection.
The bottom surface of described bottom engine room cover becomes 16 ° of angles with horizontal plane.
Engine room cover rear end, described bottom is provided with rear vents.
Cabin, described top leading flank is preceding ventilated port.
Advantage of the present utility model is as follows with effect: because the bottom of bottom engine room cover becomes 10-30 ° of angle with horizontal plane, be provided with ventilated port in the rear end of bottom engine room cover, the engine room cover rear end is bigger, and the engine room cover front end is less, is easy to air flows, strengthens radiating effect; Reduce resistance, be convenient to the wind direction adjustment, improve wind direction and catch sensitivity.

Among the figure, 1. top engine room cover, 2. bottom engine room cover, 3. bottom surface, cabin, 4. cabin trailing flank, 5. cabin, top leading flank, 6. rear vents, 7. before ventilated port.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details, but protection domain of the present utility model is not limit by embodiment.
As Fig. 3, Fig. 4 and shown in Figure 5, the trapezoidal engine room cover of the utility model wind power generating set streamline is to be made of top engine room cover 1 and bottom engine room cover 2 two-part, and this two-part engine room cover is connected to integral body by bolt, and engine room cover can adopt glass fibre reinforced plastics to make.The bottom surface, cabin 3 of bottom engine room cover 2 is connected with cabin trailing flank 4, cabin, top leading flank 5, and bottom surface, cabin 3 is a 10-30 ° of angle with horizontal plane angle, and best angle is 16 ° of folders.Engine room cover 2 rear ends in bottom are bigger, and front end is less, are provided with rear vents 6 at cabin trailing flank 4 by upper/lower positions, and cabin, top leading flank 5 is preceding ventilated port 7, and ventilated port can adopt thin wire to make.
Wind-driven generator is positioned at the cabin work that outdoor high-altitude is less and seal, and ventilation condition is relatively poor, and the heat of cabin inner accumulated is difficult for coming out comparatively fastly and unobstructedly, and temperature variation directly influences the power output of wind-driven generator.The sun directly shines the cabin, and cabin air temperature is raise, and the machine operation environment is become badly, though motor adopts forced air cooling, but the shell heat radiation that can only lean on generator.
The benefit of this model utility is, establishes ventilated port in the cabin, helps the heat radiation of motor, improves the efficient of generator; Be convenient to the wind direction adjustment, improve wind direction and catch sensitivity.
The trapezoidal engine room cover working state of this wind-driven generator, when aloft moving as Fig. 3 wind-driven generator, generator work distribute heat, wind enters in the cabin from the big end rear vents 6 of engine room cover, because the engine room cover two ends vary in size, wind is concentrated more by ventilated port before the engine room cover small end 7 flowed out, take away heat in the cabin, generator efficiency is provided in moment; Configuration design becomes streamline trapezoidal, has reduced the resistance of wind greatly, is convenient to the wind direction adjustment, improves wind direction and catches sensitivity.
