Abstract
The utility model provides a wind power generator tail fin which comprises a tail fin blade and a tail fin connection rod. One end of the tail fin connection rod is inserted into a casing of a power generator, a connector is positioned at the end, a screw hole is arranged on the connector, and a screw penetrates through the screw hole to be connected and locked with the casing of the power generator. The wind power generator tail fin is simple in structure and can be dismounted from the power generator through the fastened screw to facilitate transportation. Simultaneously, when damaged, the tail fin is convenient to maintain and replace. Furthermore, a tail fin protection cover is arranged at the connection position of the tail fin connection rod and the tail fin blade so as to prolong the service life of the tail fin.
Description
Technical field
The utility model relates to wind power plant, specifically a kind of wind-driven generator empennage.
Background technique
Wind energy if can take full advantage of, can be alleviated day by day serious energy crisis as a kind of free of contamination renewable energy sources greatly.Wind generating technology is more and more paid attention to by countries in the world in recent years, and especially in China, wind generating technology is applied widely, as building large-scale wind generating factory in the area of wind resource abundance, builds the street lamp that relies on wind-power electricity generation in the city.
Wind wheel in the wind power plant is the vitals that the kinetic energy of wind is changed into mechanical energy, directly affects wind power generating set to the utilization ratio of wind energy.In actual production process, wind wheel is affected by many external factor on the utilization ratio of wind energy, such as: wind direction, wind speed etc.Because wind direction, wind speed are all changing all the time, therefore need to adopt related control device to adjust the wind-receiving face of wind wheel, realize that wind wheel is to the maximum utilization of wind-force.
The large-scale wind generating equipment that wind power plant is used adopts complicated wind direction, air velocity transducer, adjusts the wind-receiving face of wind wheel and the angle of wind direction through computer control commander servomechanism again.This control system complex structure, with high costs, be not suitable for obviously cheaply small-size wind power-generating equipment.And small-sized wind power plant mainly is by install an empennage additional at generator, by the Wind power propelling empennage, with this wind-receiving face of adjusting wind wheel, makes the wind-receiving face of wind wheel and wind direction keep vertical angle, realizes that wind wheel is to the maximum utilization of wind-force.Because, wind power plant is in open space work, environment is more abominable, particularly run into the extreme weathers such as typhoon, the empennage of wind power plant very easily damages, and small-size wind power-generating equipment in the market, its empennage and generator all are structure as a whole, extremely difficult maintenance and replacing after empennage damages, and be not easy to transportation.
The model utility content
For above the deficiencies in the prior art and defective, the purpose of this utility model is to provide a kind of wind-driven generator empennage.
The purpose of this utility model is achieved by the following technical solution:
A kind of wind-driven generator empennage, comprise empennage blade, empennage connecting rod, an end of described empennage connecting rod is inserted in the housing of generator, and this end is provided with a jointing, this jointing is provided with screw hole, and screw is arranged in this screw hole and with the housing of this generator and is connected locking.
As optimal technical scheme of the present utility model, described screw hole and screw are provided with one group at least.
As optimal technical scheme of the present utility model, the joint of described empennage connecting rod and empennage blade is provided with an empennage guard shield and fixes.
As optimal technical scheme of the present utility model, described empennage guard shield is rounded, and retaining screw is located on this empennage guard shield uniformly along the edge of this empennage guard shield.
Compared with prior art, the utility model is simple in structure, the empennage part can be disassembled with generator by fastening screw, is convenient to transportation.Simultaneously, when empennage damages, be convenient to keep in repair and follow and change.And the joint of empennage connecting rod and empennage blade is provided with the empennage guard shield and fixes, and has prolonged the working life of empennage.
Description of drawings
Fig. 1 is the structural representation of the utility model wind-driven generator empennage.
Fig. 2 is the explosive view of the utility model wind-driven generator empennage.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
See also Fig. 1 and Fig. 2, be structural representation and the explosive view of the utility model wind-driven generator empennage.
This wind-driven generator empennage comprises empennage blade 104, empennage connecting rod 101.This empennage blade 104 is fixed in an end of empennage connecting rod 101, the side of this empennage blade 104 is the acting surface of wind-force, and the thickness of empennage blade 104 is generally thinner, for increasing the adhesive strength of empennage blade 104 and empennage connecting rod 101, prolong its working life, be provided with a rounded tail guard shield 105 in the joint of this empennage blade 104 and empennage connecting rod 101 fixing, and retaining screw is located on this empennage guard shield 105 uniformly along the edge of this empennage guard shield 105.
The other end of this empennage connecting rod 101 is inserted in the housing of generator 102, and this end is provided with a jointing 103, this jointing 103 is provided with at least one group of screw hole 107 and screw 106, this screw 106 is arranged in this screw hole 107 and with the housing of this generator 102 and is connected locking, makes empennage blade 104 and generator 102 be connected to an integral body.
The above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
