Abstract
The utility model discloses a blade defroster, its characterized in that: blade defroster set up in connecting plate (2) on aerogenerator blade (1) surface including fixed, the fixed stay has two -speed motor (3) on connecting plate (2), the output shaft of two -speed motor (3) is continuous with the eccentric cam vibration mechanism (4) of same fixed stay on connecting plate (2). This is a simple structure, low cost, and the reliability is high, the effectual blade defroster of deicing.
Description
Technical field
The utility model relates to a kind of wind-driven generator auxiliary device, particularly a kind of blade de-icing device.
Background technique
Wind-powered electricity generation is the clean reproducible energy that current most large-scale develops and utilizes prospect, and the installation amount of China's wind power generating set is advanced by leaps and bounds in recent years.Easily there is icing phenomenon in the winter time in the wind power generation unit blade running on low temp area.Cause the loading imbalance of wind wheel after wind power generation unit blade freezes, larger complete machine oscillation can be caused.Not only cause that Wind turbines is fallen and hold influence on system operation generated energy, also can cause damage to Wind turbines mechanical electric parts.Therefore wind electricity blade deicing is an extremely important technology.
Because current Wind turbines of having installed is mostly in MW class, length of blade can reach tens of rice, and boundary dimension is huge.Therefore preset as adopted the object that heating equipment realizes ice-melt, just significantly can increase cost, its feasibility is poor.
Summary of the invention
The utility model is the above-mentioned deficiency in order to solve existing for prior art, and propose a kind of structure simple, with low cost, reliability is high, the blade de-icing device that deicing is effective.
Technical solution of the present utility model is: a kind of blade de-icing device, it is characterized in that: described blade de-icing device comprises the connecting plate 2 being fixedly installed on blade of wind-driven generator 1 surface, on connecting plate 2, fixed support has double-speed motor 3, and the output shaft of double-speed motor 3 is connected with the same eccentric cam vibrating mechanism 4 be fixedly supported on connecting plate 2.
Compared with the existing technology, tool has the following advantages the utility model:
The blade de-icing device of this kind of structural type, be preset in the manufacture process of blade on blade, do not need additionally to install on blade, effectively control cost and installation difficulty, its drive part selects double-speed motor simultaneously, can provide two excited frequencies, Applicable scope is wider, and it does not need complicated piezoelectricity, the transducing devices such as ultrasonic, and under the prerequisite of effectively controlling cost, its reliability is also higher.And its preparation process is simple, and cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As shown in Figure 1: a kind of blade de-icing device, it comprises the connecting plate 2 based on, this connecting plate 2 is fixedly installed on the blade 1 of wind-driven generator, on connecting plate 2, fixed support has double-speed motor 3, the output shaft of this double-speed motor 3 is connected with eccentric cam vibrating mechanism 4, and described eccentric cam vibrating mechanism 4 is also fixedly supported on connecting plate 2.
The working procedure of the blade de-icing device of the utility model embodiment is as follows: described blade de-icing device is arranged on blade, its drive unit double-speed motor 3 is under two kinds of different rotating speeds, driving eccentric cam vibrating mechanism 4 produces two kinds of different excited frequencies, these two kinds different excited frequencies can be coupled with the high-order natural frequency of blade respectively, thus make the local of blade produce resonance, to reach the object removing icing.
Claims (1)
