The inner and outer surfaces of the lightweight blade 3 are asymmetric double arc surfaces, and the whole structure of the lightweight blade is streamline.

In this embodiment 1, the lightweight blade 3 has a conventional overall structure and dimensions.

By means of the design, when the vertical shaft wind turbine is used, natural wind acts on the outer arc-shaped surface of the lightweight blade 3, at the moment, acting force of the wind pushes the lightweight blade 3 to rotate, the lightweight blade 3 rotates to drive the wind wheel mounting seat 1 to rotate through the connecting beam 4, and further rotation power of the vertical shaft wind turbine 2 is transmitted to the shock absorption centralizer 2, and the vertical shaft wind turbine is convenient to use.

And a first connecting seat is fixedly arranged at one side position of the lightweight blade 3, which is close to the connecting beam 4.

In this embodiment 1, the first connection base is fixedly connected to the lightweight blade 3 by welding.

In this embodiment 1, the reinforcing support body employs a plurality of reinforcing plates, and the plurality of reinforcing plates are all disposed in the connection beam 4 and fixedly connected with the connection beam 4.

And the two end parts of the connecting beam 4 are respectively fixedly provided with a second connecting seat.

One end of the connecting beam 4, which is close to the wind wheel mounting seat 1, is fixedly connected with the wind wheel mounting seat 1 through a corresponding second connecting seat and a connecting bolt.

The other end of the connecting beam 4 is fixedly connected with the first connecting seat on the lightweight blade 3 through a corresponding second connecting seat by connecting bolts.

A reinforcing connecting rod 41 is fixedly installed between two adjacent connecting beams 4, and the reinforcing connecting rod 41 is used for improving the structural strength of the connecting beams 4, so that the supporting effect on the lightweight blade 3 is improved.

The design can make the overall structure of the connecting beam 4 simple, and the production is established in the convenient manufacturing to strengthening the support body through the connecting beam 4 can improve the overall structure intensity of connecting beam 4, and then make the bending resistance of connecting beam 4, anti torsion mechanical properties improve more than 5 times than thick wall pipe support arm, weight reduction 40-50%.

The wind scoop brackets 51 are fixedly arranged at positions, close to the lightweight blades 3, on the connecting beams 4 or the reinforcing connecting rods 41, hinge shafts 55 are hinged to the wind scoop brackets 51 positioned in the same longitudinal straight line, and the wind collecting blades 5 are respectively and fixedly arranged on the corresponding hinge shafts 55.

The fan blade 5 is hinged on the connecting beam 4 or the reinforcing connecting rod 41 through the cooperation of the hinge shaft 55 and the fan bracket 51, so that the assembly and the installation are convenient.

One end of the wind gathering blade 5, which is close to the rear edge of the corresponding lightweight blade 3, is a windward surface 53, and after the wind gathering blade 5 rotates to enable the front edge of the wind gathering blade to be in contact with the back surface of the lightweight blade 3, the windward surface 53 is obliquely arranged, and a wind gathering bucket is formed between the windward surface 53 and the back surface of the lightweight blade 3.

One end of the wind gathering blade 5, which is close to the front edge of the corresponding lightweight blade 3, is an arc surface 54, and after the front edge of the wind gathering blade 5 is rotated to be in contact with the back surface of the lightweight blade 3, a choke arc surface is formed between the arc surface 54 and the back surface of the lightweight blade 3.

In such design, at least one wind gathering blade 5 is added on each group of connecting beams 4 for supporting each lightweight blade 3, under the action of improving the resistance moment by matching the wind gathering blade 5 with the lightweight blades 3, the vertical shaft wind wheel 2 is pushed to rotate along the front edge direction and drive the generator to generate electricity, meanwhile, strong resistance moment generated by the wind gathering wind hopper 5 can also jointly push the wind wheel to accelerate the forward rotation speed and enhance the rotation moment, and the generated energy and the generated electricity efficiency of the generator are increased; after the wind gathering blade 5 is added to the vertical axis wind wheel 2, the starting moment of the wind wheel is increased, and the breeze starting performance of the wind wheel is improved; and secondly, the generating capacity and the generating efficiency of the generator are improved.

When the rotating speed of the vertical-axis wind wheel 2 is within the maximum allowable rotating speed value, the front edge of each wind gathering blade 5 is kept in contact with the back surface of the lightweight blade 3; the windward side 53 and the back of the lightweight blade 3 form a wind collecting hopper, at the moment, the cut wind power is converted into forward thrust to the vertical axis wind wheel 2, and the forward thrust generated by the lightweight blade 3 is combined to strengthen the rotating speed and the rotating moment of the wind wheel, so that the generating capacity and the generating efficiency of the generator are improved.

When the rotation speed of the wind wheel is close to the maximum allowable rotation speed value or a severe strong wind is encountered, wind power cut into the wind collecting hopper pushes the wind collecting blade 5 to rotate along the hinge shaft 55, at the moment, the front edge of the wind collecting blade 5 moves to the side far away from the lightweight blade 3, the wind collecting blade 5 is opened, at the moment, a part of wind power is discharged, and the forward thrust generated by the wind power is reduced.

When the wind pressure of the wind collecting blade 5 is started to a state that the windward side 53 is relatively parallel to the back surface of the lightweight blade 3, the wind discharging quantity is maximum, and the wind collecting blade 5 does not generate forward thrust to the rotation of the wind wheel; in this case, the main wing continues to generate forward thrust for the rotation of the wind wheel.

When the two wind gathering blades 5 rotate past the maximum wind pressure point, the opened wind gathering blades 5 can move the front edge of the wind gathering blade 5 to one side close to the lightweight blade 3 under the reduction of wind pressure, so that the wind gathering blade 5 gradually closes the opening to form a new closed state.

When the two wind gathering blades 5 rotate to the arc surface 54 to be a windward surface, a choke arc surface is formed between the arc surface 54 of the closed wind gathering blade 5 and the back surface of the lightweight blade 3, at the moment, the choke arc surface is the windward surface, after wind power works on the choke arc surface, the pressure of wind power can be converted into the maximum reverse thrust for the forward rotation of the wind wheel, the forward rotation of the vertical shaft wind wheel 2 is blocked, the forward rotation speed and torque force of the vertical shaft wind wheel 2 are reduced, the damage to the generator caused by the overhigh wind wheel rotation speed is prevented, and the normal power generation operation of the generator is protected.

The side surfaces of the two wind gathering blades 5, which are far away from each other, are fixedly connected with a hinge shaft 55 through a connecting lug plate, and the hinge shafts 55 are respectively hinged with the corresponding wind scoop brackets 51.

When the real-time wind pressure is greater than the wind pressure preset threshold value, the wind pressure is excessively large, at the moment, the main controller sends a control signal for controlling the retractable rod 57 to retract, at the moment, the retractable rod 57 retracts to drive the wind gathering blade 5 to swing along the hinge shaft 55, so that the front edge of the wind gathering blade 5 moves to the side far away from the lightweight blade 3, and at the moment, wind unloading operation is performed.

When the real-time wind pressure is smaller than the wind pressure preset threshold value, the wind pressure is too low, at the moment, the main controller sends a control signal for controlling the opening and closing telescopic rod 57 to extend, at the moment, the opening and closing telescopic rod 57 extends to drive the wind gathering blade 5 to swing along the hinge shaft 55, the front edge of the wind gathering blade 5 is kept in contact with the back surface of the lightweight blade 3, and at the moment, the windward side 53 of the wind gathering blade 5 and the back surface of the lightweight blade 3 form a wind gathering hopper.

And the operation of the opening and closing telescopic rod 57 can be controlled according to the wind speed, when the wind speed is too low and the windward side 53 is on the windward side, the opening and closing telescopic rod 57 on the wind collecting blade 5 stretches out, so that the front edge of the wind collecting blade 5 keeps contact with the back surface of the light-weight blade 3, and the windward side 53 of the wind collecting blade 5 and the back surface of the light-weight blade 3 form a wind collecting hopper.

When the wind speed is too low, the arc-shaped surface 54 is positioned on the windward side, the retractable rod 57 on the wind gathering blade 5 is retracted, so that the front edge of the wind gathering blade 5 moves to the side far away from the lightweight blade 3, and the arc-shaped surface 54 positioned on the windward side does not block wind power, so that the vertical shaft wind wheel 2 can be ensured to rotate under the condition of breeze, and further the power generation operation is realized.

The opening and closing push-pull device 56 is used for pulling the two wind gathering blades 5 to swing along the hinge shaft 55 in an initial state, so that the rear edges of the wind gathering blades 5 are contacted with the back surfaces of the corresponding lightweight blades 3.

When the pressure of the wind force acting on the wind gathering blade 5 is larger than the starting tension of the opening and closing push-pull device 56, the opening and closing push-pull device 56 works to enable the push-pull mandrel 562 to extend out, so that the wind gathering blade 5 swings along the hinge shaft 55, the rear edge of the wind gathering blade 5 moves to the side far away from the lightweight blade 3, and further the wind gathering blade 5 is opened, and wind unloading operation is performed.

After the opening and closing push-pull device 56 is installed, the complete closing and working of the wind gathering blade 5 in the rated wind speed can be automatically realized, firstly, the starting performance of the wind wheel is improved, and the breeze (1-2 m/s) starting is realized; and secondly, more breeze push-pull is received under the condition of breeze, the rotation speed of the wind wheel is accelerated, the generating capacity and the generating efficiency are improved, the automatic opening and closing of the wind gathering blade 5 under the pressure of different wind speeds are automatically realized, and the stable operation of the wind wheel under the condition of strong wind is regulated.

When the pressure of wind reaches the rated wind speed of 11m/s, the wind gathering blade 5 starts to compress the opening and closing push-pull device 56 to start to open and close, the opening amount is related to the amount of wind larger than the rated wind speed of 11m/s, when the wind speed reaches 25m/s, the wind gathering blade 5 is fully opened (opened to the maximum value), at the moment, the windward side 53 of the wind gathering blade 5 is parallel to the flow direction of the wind, the inflowing wind is fully naturally discharged, and the thrust to the front surface of the wind gathering blade 5 is not generated.

After the opening and closing push-pull device 56 is installed, the rotation speed of the wind wheel is automatically reduced under the condition that the wind gathering blade 5 encounters severe strong wind, the wind wheel is prevented from galloping, and normal power generation is kept continuously.

When the wind speed is greater than 25m/s, the generator set is overloaded and normal power generation cannot be implemented; however, after the opening and closing push-pull device 56 is installed, the front surface of the wind gathering blade 5 is fully opened, the speed increasing force is not provided for the vertical axis wind wheel 2 any more, meanwhile, as the wind pressure is rapidly reduced after the wind gathering blade 5 rotates through the front windward surface, when the wind pressure is smaller than 25m/s, the opening and closing push-pull device 56 rapidly pushes the wind gathering blade 5 to be closed under the pushing force of the pressure spring 5602, when the back surface of the closed wind gathering blade 5 rotates to the other side, the pressure of the wind received by the arc-shaped surface 54 of the wind gathering blade 5 is opposite to the rotating direction of the vertical axis wind wheel 2, the rotating speed of the vertical axis wind wheel 2 is blocked, the rotating speed of the wind wheel is reduced, the normal power generation requirement under the condition of heavy wind is met, the wind generation accident is effectively prevented, the normal power generation work under the condition of heavy wind is realized, and the power generation capacity and the power generation efficiency are improved; and the reciprocating opening and closing circulation work is performed in sequence.
