the wind wheel blades 2 are arc-shaped, the wind wheel blades 2 are vertically arranged on the circular support plate 3, the bottom edges of the wind wheel blades 2 are connected with the circular support plate 3, one side of each wind wheel blade 2 is connected with the wind wheel shaft 1, the other side of each wind wheel blade extends outwards, the height of each wind wheel blade 2 decreases outwards from the wind wheel shaft 1, and the wind wheel blades 2 are uniformly distributed on the circular support plate 3;
the guide plate 4 is arranged on the periphery of the wind wheel blade 2, the guide plate 4 is a circular arc-shaped plate, and the guide plate 4 is uniformly distributed on the circular support plate 3.
The height of the wind wheel blade 2 is larger than that of the guide plate 4.
As shown in fig. 2, a fairing 5 is further arranged on the wind wheel, and the fairing 5 is an annular baffle arranged around the circular support plate 3; the height of the fairing 5 is the same as the height of the deflector 4.
The flow constriction formed by the fairing 5 and the deflector 4 accelerates the flow of the air in the passage. Meanwhile, the airflow is adjusted to the wind direction through the fairing 5, the overall airflow is increased like the airflow on the concave surface of the windward wheel blade 2, and the airflow on the convex surface of the windward wheel blade 2 is greatly reduced, so that the wind wheel can generate larger torque, and can still be automatically started at lower wind speed, the available wind speed range is improved, the fan efficiency is higher at the same wind speed, and the fairing 5 has low pressure on the windward wheel blade 2, and cannot damage the windward wheel blade 2.
A support frame 6 is arranged below the circular support plate 3. When the vertical axis wind power energy-saving generator is connected with devices such as a lamp post 7 and the like, the vertical axis wind power energy-saving generator is fixed through a support frame 6.
The wind wheel blades 2 are made of glass fiber reinforced plastics.
The glass fiber reinforced plastic is made of plastic fiber reinforced plastic, which can be epoxy resin or glass fiber impregnated with the epoxy resin or carbon fiber and unsaturated resin with different lengths. The reinforced plastic has high strength, light weight and ageing resistance. The blade surface may be entangled with glass fibers and epoxy, while the rest is filled with foam. The foam acts to ensure that it is stable and has a reduced weight, thereby allowing the blade to increase the wind capture area while meeting stiffness.
The tower of the wind power energy-saving generator is made of carbon fiber composite materials with high strength, high temperature resistance, corrosion resistance and frictional resistance.
The internal structure of the wind power energy-saving generator mainly comprises stainless steel.
The vertical axis wind power energy-saving generator is a resistance type generator, and mainly utilizes resistance generated by air flowing through wind wheel blades as driving force. The wind wheel blades of the wind motor are asymmetric in shape in the windward direction, so that different air resistance is caused, a moment around a central shaft is generated, and the wind wheel rotates.
The wind power conversion efficiency can be furthest exerted no matter in a wind environment with a wider space or a smaller space, the maximum wind capturing effect and the minimum wind resource waste are realized through the modes of facility structure adjustment, replacement and the like, and the renewable energy sources are fully utilized. With the rapid development of the construction of the expressway in China, the requirements on electromechanical equipment and power supply systems along the expressway are higher and higher, and the power supply system is gradually developed to a novel power supply mode.
Theoretical design calculation of the wind power energy-saving generator is as follows:
the stress of the wind power energy-saving generator is analyzed in the operation process, the section of each blade is semicircular, the overlapping rate of the blades 2 of the wind wheel is not considered, only the stress of the blades of the windward wind wheel is considered, and the stress of the blades of the leeward wind wheel is not considered. The incoming flow wind speed of the blade in the first quadrant at the circle center is V, the rotation linear speed U of the blade is as follows:
a＝(V-Un)/V
at the moment, the power of the wind power energy-saving generator is as follows: pc＝F1·Un＝1/2ρACd(V-Un)2·Un＝1/2ρACdV3a2(1-a)
The wind energy utilization rate C of the wind power energy-saving generator is the ratio of the wind power to the power generated on the wind sweeping area of the wind speed wind wheel blade 2 at infinity:
in the formula
n-impeller rotational speed (rpm);
d, the diameter (m) of the arc wind wheel blade;
rho-air Density (1.225 kg/m)3)；
A-impeller swept area (m)2)；
Cd-arc wind turbine blade drag coefficient;
Pc-the average output power (W) of the wind rotor;
Cp-a wind energy utilization factor.
The tip speed ratio h and the wind energy utilization ratio Cp of the wind energy-saving generator with the fairing are defined as follows:
in the formula:
a-the wind sweeping area of the impeller;
v-incoming wind velocity at infinity;
r is the radius of the impeller.
Under the same other conditions, the wind energy-saving generator with or without the fairing is analyzed to conclude that the maximum Cp value of the wind turbine without the fairing is 15%, the tip speed ratio corresponding to Cp is 0.41, and the effective tip speed ratio range of the impeller is 0.198-0.691. The maximum Cp value of the wind turbine provided with the fairing is 35%, the corresponding tip speed ratio is 0.76, and the effective tip speed ratio range of the impeller is 0.55-1.02. This can result in: after the fairing is installed, the maximum wind energy utilization rate of the energy-saving generator of the wind turbine is improved, and the tip speed ratio corresponding to the maximum wind energy utilization rate is also improved, namely the wind speed value of the energy-saving generator of the wind turbine in the optimal working state is improved.
The number of the best guide plates forming the accelerating wind tunnel is 8, the cross section of each guide plate is arc-shaped, and the guide plates are uniformly distributed around the impeller to form the accelerating wind tunnel.
When the impeller works, the forward concave wind wheel blades generate forward torque, the backward convex wind wheel blades generate reverse torque, after airflow passes through the accelerating wind tunnel, the wind direction is changed, the airflow acting on the backward convex wind wheel blades is reduced, the airflow acting on the forward concave wind wheel blades is increased, and the forward torque and the reverse torque generated by the impeller are increased.
