A kind of combined type wind driven generator blade

Technical field

The utility model relates to a kind of blade, specifically, relates to a kind of combined type wind driven generator blade.

Background technology

Wind energy, as a kind of clean regenerative resource, is more and more subject to the attention of countries in the world. Its amount of accumulateing is huge, the whole worldWind energy is about 2.74 × 10^9MW, and wherein available wind energy is 2 × 10^7MW, can be total than the water that can develop on the earthAmount is also wanted large 10 times.

Wind-power electricity generation is that the kinetic energy of keeping watch transfers electric energy to. Wind-driven generator is that wind energy is converted to mechanical power, mechanical power rotor drivenRotation, the power equipment of final output AC electricity. In a broad sense, wind energy is also solar energy, so also can say wind-power electricity generationMachine, is a kind of taking the sun as thermal source, the heat energy utilization generator taking atmosphere as working media.

At present the blade on wind power plant is owing to operating in for a long time in the comparatively severe situation of operating mode, its structural strength requirementHigher, therefore need a kind of intensity of design badly high, and lightweight novel vane structure. Existing blade is integral type knot simultaneouslyStructure, comparatively inconvenience when causing transport and installing.

Utility model content

The problems referred to above that exist for prior art, the purpose of this utility model is to provide a kind of combined type wind driven generator blade.

A kind of combined type wind driven generator blade, comprises shell and inner support frame, and described shell is hollow-core construction and setting in itHave the inner support frame of several piece setting parallel to each other, described shell is made up of several sections of shell segments, between adjacent described shell segments, passes throughFlange is connected, and described inner support frame is provided with the head end for propping up shell inner edge, be positioned at be provided with after described head end forWith the groove that the projection being arranged in shell matches, described groove is provided with front vallecular cavity and rear vallecular cavity, described front vallecular cavity and afterBetween vallecular cavity, be provided with oblique location-plate, described projection is provided with front protruding end and rear protruding end, described front protruding end and rear protrudingBetween origin or beginning, be provided with oblique projection, be provided with the tail for propping up shell inner edge be positioned at groove on described inner support frame afterEnd, is provided with the tail end locating slot for matching with the tail end projection being arranged in shell on described tail end.

Preferably, be provided with oblique brace rod in described head end, one end of described oblique brace rod is connected on head end, the other endBe connected on the cell wall of front vallecular cavity.

Preferably, the both sides that are positioned at described inner support frame are respectively provided with a groove, and respectively establish the both sides that are positioned at described inner support frameBe equipped with a tail end locating slot.

Preferably, between the tail end locating slot of the both sides of described inner support frame, be provided with reinforcement.

Preferably, on described head end and tail end, be provided with structural arc chord angle.

Compared with prior art, the utility model provides combined type wind driven generator blade, is provided with shell and inner support frameStructure, shell can be designed to various shapes according to hydrodynamics, and it is whole that the existence of inner support frame has simultaneously improved blade greatlyBody strength and stiffness, and by the cooperation between groove and projection, tail end projection and tail end locating slot, have strengthened cooperationStability, thereby make both tightr in conjunction with obtaining. Head end and tail end prop up respectively the inner edge of shell simultaneously, further improveCoordinate reliability. Fabricated structure, has saved cost of transportation greatly simultaneously, has reduced assembling difficulty, has improved productAdaptability.
