Description
Technical Field
The invention relates to the field of power generation devices, in particular to a double-wind-wheel vertical-axis wind power generation device which is a power generation device for generating power by utilizing renewable energy sources such as wind power sources, river water power sources, ocean current power sources and the like.
Background
The human faces the exhaustion of fossil fuel resources, renewable energy sources such as wind power energy sources, river water power energy sources and ocean water power energy sources are developed and utilized to generate electricity, the reserves of the renewable energy sources are huge, the energy sources are utilized in an environment-friendly way, the application prospect is wide, and the total installed amount of wind turbine power generation in the world is increased year by year at present.
Wind wheels of wind turbines in use today are mainly of two types, one type being a horizontal axis wind wheel and one type being a vertical axis wind wheel. Compared with the two types of wind turbines, the lift force (horizontal axis) technology is mature and is widely applied, and the generator of the power generation device is arranged at the top of a wind tower, so that the installation and maintenance are inconvenient. The blade of the large horizontal axis wind turbine is very heavy, the technical requirement for manufacturing the blade is high, the manufacturing cost is high, the blade is easy to damage, the starting wind speed of power generation equipment is high, and the power generation equipment cannot be used in a breeze state. The horizontal axis wind turbine must be designed with a windward device to stabilize its windward function. The other type of resistance type vertical axis (vertical axis) wind turbine is mainly in phi type, H type and S type, and other types are difficult to enlarge because of structural limitation, such as high starting wind speed, small wind area or large processing difficulty of the rotating wings. As the resistance of the fan blade of the general vertical axis wind turbine is relatively high in the windward resistance area, the problems of low efficiency and unbalanced output moment exist.
However, compared with the horizontal axis wind turbine, the vertical axis wind turbine has the advantages of simple structure, large rotation moment, low production cost, low operation and maintenance cost and the like, and does not need to design a windward device. Most importantly, the vertical axis wind turbine can be placed on the top of a building, and the wind turbine and the building are organically combined together, so that the wind turbine can be popularized and used in a large amount. The wind wheel of the wind turbine is a key component of the wind turbine, and the key point of improving the wind energy utilization rate of the wind turbine is how to solve the problems of low efficiency and unbalanced output moment of the wind wheel of the current vertical axis wind turbine. The wind wheel of the vertical axis wind turbine with simple structure, easy processing, high wind energy utilization rate and balanced output moment is designed, which is a difficult problem of a wind power system, and the renewable energy source of wind energy can be widely applied only by solving the difficult problem. In addition, the matching of the wind turbine and the generator also has a certain problem, and the wind turbine can not generate power even in breeze.
Chinese patent (application No. 92236222. X) discloses a prior application named as a 'sail type wind power device', wherein the device is characterized in that 3-4 sails are radially and uniformly distributed on a vertical shaft to form a wind wheel, the sails are rectangular frames, a row of louver blade assemblies can be arranged in the middle of each frame, and steel wires can be used for crisscross forming a net frame and metal sheets or nylon and canvas which are penetrated and hung on the net wires and distributed in a fish scale shape. The sail type wind power device has the defects that the sail blades cannot lift and are damaged when the wind turbine encounters a crazy wind, the sail blades can be freely adjusted in a windward area, but the resistance generated by the sail blades is larger, the key is that only one side of the vertical shaft generates power, and the other side of the sail generates resistance in the windward area to consume a large part, so that the wind power utilization rate is lower, the output torque is unbalanced, and the wind power device is the same as the principle of the traditional vertical shaft wind turbine in ancient China, and the wind turbine is not applicable.
In the traditional vertical axis wind turbine device, the wind turbine sail generates power in a downwind area on one side of the vertical axis, and when the wind sail enters a windward area on the other side of the vertical axis, resistance is generated, so that the efficiency of the wind turbine is reduced, and the output moment is unbalanced.

According to the invention, the inner wind wheel assembly A and the outer wind wheel assembly B rotate in opposite directions according to different hanging methods of the wind sail blades 15, one side of the wind sail blade 15 is fixed on the radially outer sail supporting net 13 of the inner wind wheel sail bracket in the downwind area and is positioned in front of the sail supporting net 13 in the windward direction, when the wind blows, the wind is blown on the sail supporting net 13 (the wind direction is vertical to the paper surface as shown by A-1 in fig. 11) to generate thrust on the sail supporting net 13, the sail supporting net 13 generates thrust on the sail supporting net supporting rod sail bracket 14, the sail supporting net supporting rod sail bracket 14 generates thrust on the upper supporting member and the lower supporting member of the wind wheel to enable the inner wind wheel to rotate in the anticlockwise direction, and when the wind sail blade 15 rotates to the upwind area, the wind blade is positioned behind the sail supporting net (the wind direction is vertical to the paper surface as shown by A-2 in fig. 11) to be blown off the sail supporting net, and the resistance of the wind wheel in the windward area is reduced along with the wind. Thus, when the inner wind wheel rotates, the sail blades 15 generate power in the downwind area and generate resistance to cycle back and forth in the windward area. Similarly, in the downwind region, one side of the wind vane 15 is fixed on the radially outer supporting sail net 13 of the outer wind wheel sail bracket, and is positioned in front of the supporting sail net 13 in the windward direction, when the wind blows, the wind blows on the supporting sail net 13 (as shown by B-1 in fig. 11, the wind direction is vertical to the paper surface), thrust is generated on the supporting sail net 13 by the supporting sail net supporting rod sail bracket 14, thrust is generated on the upper supporting member and the lower supporting member of the wind wheel by the supporting sail net supporting rod sail bracket 14, the outer wind wheel rotates clockwise, and when the wind vane 15 rotates to the upwind region, the wind vane is positioned behind the supporting sail net (as shown by B-2 in fig. 11, the wind direction is vertical to the paper surface) and blown off the supporting sail net by the wind, so that the resistance of the wind wheel in the windward region is reduced along with the wind. Thus, when the wind wheel rotates, the wind sail blades 15 generate power in the downwind area and generate resistance to cycle back and forth in the windward area.
To prevent the occurrence of the over-positioning of the wind sail blades 15, a plurality of stop bars 14-1 (shown in fig. 7 and 8) made of lightweight material are vertically installed on the sail supporting pole sail brackets 14 outside the inner sail bracket assembly E and the outer sail bracket assembly F to prevent the wind wheel from rotating and stopping due to the wind blades 15 being blown to the front of the sail supporting poles by turbulent wind (such as cyclone wind) in the windward region, and the stop bars 14-1 cannot affect the up-and-down sliding of the wind blades 15 on and above the sail supporting poles 13 on the sail supporting pole sail brackets 14 pulled by the lift sail ropes 16. The sail blades 15 on the sail cloth 13 may be suspended in one or more pieces depending on the size of the wind turbine. The radial width of the vertical shaft of the wind turbine, the radial width of the vertical shaft of the outer sail bracket assembly F and the number of the hanging sail blades 15 on the vertical shaft and the width of the hanging sail blades 15 can be changed by adjusting the radius of the outer wind wheel assembly B or the radius of the tower support assembly C of the inner wind wheel assembly A, and the rotating moment of the inner wind wheel assembly B or the radius of the tower support assembly C of the outer wind wheel assembly A, so that the rotating moment of the inner wind wheel assembly A and the rotating moment of the outer wind wheel assembly B are equal, and the rotation of the power output main shaft 27 is ensured to be more stable.
Referring to fig. 12, when the vertical axis (inner wind wheel axis 1, outer wind wheel axis 2) of the wind turbine is unchanged, the stop lever 14-1 and the wind sail blades 15 on the two inner wind sail bracket assemblies E and the two outer wind sail bracket assemblies F are exchanged from front to back, the inner wind wheel assembly a rotates clockwise in this state, the outer wind wheel assembly B rotates anticlockwise, and the rotation directions of the inner wind wheel assembly a and the outer wind wheel assembly B are related to the hanging method of the wind direction and the wind sail blades 15 in summary, because the inner wind wheel assembly a and the outer wind wheel assembly B rotate horizontally in which direction, the double wind wheel vertical axis wind power generation device of the invention does not need to be equipped with a wind aligning device.
The vertical shaft of the wind turbine adopts an inner shaft and an outer shaft (an inner wind wheel shaft 1 and an outer wind wheel shaft 2), an outer wind wheel assembly B is connected with the outer wind wheel shaft 2 to push the outer wind wheel shaft 2 to rotate, and an inner wind wheel assembly A is connected with the inner wind wheel shaft 1 to push the inner wind wheel shaft 1 to rotate. The inner wind wheel assembly A and the outer wind wheel assembly B are hung in front of the sail supporting net 13 in the windward direction, and the sail blades 15 are positioned on two sides of the vertical shaft of the wind turbine, so that the inner wind wheel assembly A and the outer wind wheel assembly B can rotate in opposite directions under the action of wind force. The phase angles of the upper sail supporting net 13 of the inner wind wheel assembly A and the outer wind wheel assembly B are adjusted to enable the inner wind wheel shaft bevel gear 22 and the outer wind wheel shaft bevel gear 25 to generate 180-degree symmetrical double-power pushing force on the power output main shaft bevel gear 26, so that power can be generated on two sides of a vertical shaft of the wind turbine, and double power can be generated. Because the inner wind wheel assembly A and the outer wind wheel assembly B rotate in opposite directions, the sail blades 15 on the outer wind wheel assembly B can partially shield or shelter the sail blades 15 on the inner wind wheel assembly A in the downwind power acting area so as to reduce the resistance of the inner wind wheel assembly A in the upwind resistance area. Similarly, the sail blades 15 on the inner wind wheel assembly A can partially shield or shelter the sail blades 15 of the outer wind wheel assembly B in the downwind power acting area so as to reduce the resistance of the outer wind wheel assembly B in the upwind resistance area, and thus the efficiency of the wind turbine can be improved. The supporting roller 18 rotates through the opposite friction of the supporting roller 18 between the supporting roller circumferential track 17 and the inner wind wheel upper ring circumferential track 3 which are arranged on the inner side of the outer wind wheel assembly B and the inner wind wheel lower ring circumferential track 4, the rotation of the supporting roller 18 can couple and transfer the power and resistance generated by the inner wind wheel assembly A and the outer wind wheel assembly B to the inner wind wheel shaft 1 and the outer wind wheel shaft 2, and the rotation of the inner wind wheel bevel gear 22 and the outer wind wheel bevel gear 25 enables the rotation of the power output main shaft 27 to be more stable. because power is generated on two sides of the vertical shaft of the wind turbine, the power moment generated on two sides of the vertical shaft of the wind turbine is equal by adjusting the total area of the sail blades 15 of the inner wind wheel assembly A and the outer wind wheel assembly B, and the problem of unbalanced output moment of the traditional vertical shaft wind turbine is well solved. The sail supporting net 13 is formed by the automobile tire wires, so that the sail supporting net 13 is high in strength and soft. The sail supporting net support bar sail bracket 14 on the inner wind wheel assembly A is arranged between the support bar 7 on the top of the inner wind wheel rim and the support bar 8 on the bottom of the inner wind wheel rim, the sail supporting net support bar sail bracket 14 on the outer wind wheel assembly B is hung between the outer wind wheel sail supporting net support bar top beam 10 and the outer wind wheel sail supporting net bottom beam 11, a device capable of sliding is arranged on the sail supporting net 13 and sleeved on the sail supporting net support bar sail bracket 14, the lifting sail rope 16 is arranged on the upper part of the sail supporting net 13, the sail supporting net 13 and the sail blades 15 hung on the sail supporting net 13 can be pulled to move up and down on the sail supporting net support bar sail bracket 14, when a user encounters a mania wind, the sail supporting net 13 and the sail blades 15 hung on the sail supporting net 13 can be lowered together, and the sail supporting net 13 and the sail blades 15 hung on the sail supporting net 13 can be lifted together after the mania wind. Since the phase angle of the sail blades 15 is varied, the generated power is not uniform, and thus the inertia rotary disk 28-1 is mounted on the power output shaft 27 for moment of inertia compensation.
The generator set assembly D consists of a plurality of generators, wherein the generators are permanent magnet generators, each generator in the generator set assembly D is connected with each level of speed increasing wheels through belts in the process of increasing the rotating speed of a power output main shaft, four levels of speed increasing wheels with the highest rotating speed are connected with a first-level generator with the smallest power in a matching way after the speed increasing, three levels of speed increasing wheels with the higher rotating speed are connected with a second-level generator with smaller power in a matching way, two levels of speed increasing wheels with the slower rotating speed are connected with a third-level generator with the larger power in a matching way, one level of speed increasing wheels with the slow rotating speed is connected with a fourth-level generator with the large power in a matching way, when some generators are in idle state, the load or idle state of the generators can be completed through an industrial controller, a circuit switch closes the rotor coil of the permanent magnet generator and the electrical appliance to form a closed loop generator to generate power, and the circuit switch opens the rotor coil of the permanent magnet generator and the electrical appliance does not form the closed loop generator to idle state to generate power. When the wind speed is high, the wind wheel speed of the wind machine is high, the power is high, the primary speed increaser with low speed drives the secondary generator with high power to generate electricity, and the intelligent combination of the generators of the generator set can enter the load to generate electricity through the industrial personal computer to realize small wind power generation and large wind power generation.
