Abstract
A kind of device that improves wind power generating set wind energy utilization, it is characterized in that multi-disc triangle fin to be arranged on the leeward side of blade of wind-driven generator, and company's being aligned, the starting point of line is apart from 10% of root of blade length of blade, apart from 10% place of blade inlet edge blade chord length, length of installation is 40% of blade total length.The device of raising wind power generating set wind energy utilization of the present utility model, by installing triangle fin additional, wind-driven generator blade face air-flow is scanned, when air-flow is through out-of-date, triangle fin rear end can produce vortex, goes out stream end at blade, between vortex, interact and become unified direction, reduce the resistance acting on blade, effectively stoped blade overdraught premature disengagement, increased lift, prevent the too early generation of stall, improved the utilization ratio of wind power generating set wind energy.Improved the generated energy in 6-12m/s wind speed section, annual electricity generating capacity can improve 4%-6%.
Description
Technical field
The utility model relates to wind power generating set field, particularly a kind of device that improves wind power generating set wind energy utilization.
Background technique
In wind power generating set running, blade surface brings many adverse consequencess because producing disadvantageous airflow breakaway, as resistance increment, lift reduce, causes unit to shift to an earlier date stall power and declines.In addition, before wind power generating set does not reach rated wind speed, the air-flow premature disengagement of blade surface, causes maximum lift coefficient to reduce, and wind energy availability reduces.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of air-flow premature disengagement that stops wind generator set blade surface, increases the device of the raising wind power generating set wind energy utilization of wind power generating set generated energy.
The utility model solves the problems of the technologies described above with following technological scheme:
The utility model improves the device of wind power generating set wind energy utilization, multi-disc is arranged on to the leeward side (being blade suction side) of blade of wind-driven generator and connects being aligned with the triangle fin that stainless steel materials is made, the starting point of line is in be length of blade apart from root of blade 10% place, apart from 10% place of blade inlet edge blade chord length, length of installation is 40% of blade total length.
In the line being linked to be by triangle fin, between every two adjacent triangle fins, distance is the length of triangle fin.
Triangle fin is formed by fixedly connecting by paster and two triangular plates, and two triangular plates are connected with paster is vertical.
The present invention improves the device of wind power generating set wind energy utilization, by installing triangle fin additional, in the time that wind-driven generator blade face has air-flow to scan, air-flow is become a mandarin to hold by blade and flows through after triangle fin front end, (being fin tip) can produce high-octane vortex in its back-end, go out stream end at blade, after the low-energy boundary layer air in this eddy current and its downstream flows and mixes, just energy is passed to boundary layer, after making the boundary layer flow field acquisition additional-energy in adverse pressure gradient, air-flow becomes unified direction, can continue to be attached to blade surface, effectively stop blade overdraught premature disengagement, reduce the resistance acting on blade, increase lift, prevent the too early generation of stall, improve the utilization ratio of wind power generating set wind energy.Improved the generated energy in 6-12m/s wind speed section, annual electricity generating capacity can improve 4%-6%.

In figure: 1-root of blade, the 2-blade suction side end that becomes a mandarin, 3-blade suction side goes out stream end, 4-blade tip, 5-triangle fin, 6-paster, 7-triangular plate
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
The utility model improves the device of wind power generating set wind energy utilization, multi-disc triangle fin is arranged on to the leeward side (being blade suction side) of blade of wind-driven generator and connects being aligned, the starting point of line is in be length of blade apart from root of blade 10% place, apart from 10% place of blade inlet edge blade chord length, length of installation is 40% of blade total length.
In the line being linked to be by triangle fin, between every two adjacent triangle fins, distance is the length of triangle fin.
Triangle fin is formed by fixedly connecting by paster and two triangular plates, and two triangular plates are connected with paster is vertical.
Because SUS303 Austenitic stainless steel in coastal air ambient can be suitable for outdoor applications completely, working life is longer, in 20 years, can not scrap, and therefore triangle fin material can be used 0.5mm SUS303 Austenitic stainless steel materials.Its monolithic weight is only several grams, and corner all does passivation, therefore can not have any threat to unit and surrounding enviroment thereof.When installation, paster is attached to the leeward side of blade of wind-driven generator by designing requirement, two triangular plates outwardly; Require the bond strength of adhesive used can ensure that paster does not come off in 10 years.
Paster is clean blade and paster attachment face before installing, and on paster attachment face, must not have greasy dirt and dust.When installation, keep blades installation face dry, can use if desired heat gun heat drying.When installation, ensure that paster surface panel beating glue smears evenly.Between blade and paster sticking veneer, to ensure seamless or bubble.Installation unit after solidifying 12 hours can move.Ambient temperature during lower than-10 DEG C, can affect gluing construction effect, should not construct.
