Description

Tower power station using vertical axis wind turbines

Technical Field

The utility model relates to the technical field of new energy power generation, in particular to a tower power station using a vertical axis wind turbine.

Background Art

As renewable energy is clean and has low greenhouse gas emissions, the use and development of renewable energy has attracted increasing attention from all countries, among which solar power generation and wind power generation are the most valued.

Wind power generation devices generally include horizontal-axis wind turbines and vertical-axis wind turbines. Horizontal-axis wind turbines require the rotating axis of the wind rotor to be parallel to the wind direction to generate electricity, while vertical-axis wind turbines do not need to face the wind when the wind direction changes. This is a major advantage over horizontal-axis wind turbines. It not only simplifies the structural design, but also reduces the gyroscopic force of the wind rotor facing the wind. Therefore, the starting wind speed requirement of vertical-axis wind turbines is much lower than that of horizontal-axis wind turbines.

However, since the power generation capacity of vertical axis wind turbines is relatively small, when a power station uses vertical axis wind turbines to generate electricity, in order to increase the overall power generation capacity of the power station, it is necessary to increase the number of vertical axis wind turbines so that multiple vertical axis wind turbines can generate electricity in parallel, thereby increasing the overall power generation capacity. However, this method requires a large amount of area, greatly increases the complexity of installation, and increases equipment costs.

As shown in Figures 1 and 2, the tower power station using vertical axis wind turbines in this embodiment includes an installation tower 1. The installation tower 1 includes several power generation layers for setting vertical axis wind turbines 2. The rotation axes of two vertical axis wind turbines 2 in adjacent power generation layers rotate in opposite directions. A positive wind gathering device 3 is provided around the vertical axis wind turbine 2 whose rotation axis rotates in the forward direction, and a reverse wind gathering device 4 is provided around the vertical axis wind turbine 2 whose rotation axis rotates in the reverse direction.

Among them, the tower frame of the mounting tower 1 is a multi-layer lattice steel structure, which can be any one of a cylindrical, elliptical, rectangular, and polygonal column structure, and can bear weight, be ventilated, resist outdoor corrosion, and be easy to install. The overall structure can be assembled as one piece, or each layer can be assembled independently and then stacked into one piece. The power generation layer can be set to 1-60 layers according to actual needs. The tower power station in this embodiment is cylindrical, and its power generation layer is illustrated by taking 4 layers as an example. The vertical axis wind turbine 2 is installed at the center of the power generation layer. The power generation layer where the vertical axis wind turbine 2 with the shaft rotating in the forward direction is located is the forward power generation layer, and the vertical axis wind turbine 2 with the shaft rotating in the reverse direction is the reverse power generation layer. The forward power generation layer and the reverse power generation layer are arranged alternately.

In this embodiment, the installation tower 1 includes a bottom plate 11, a partition plate 12 and a top plate 13. The partition plate 12 is disposed between the bottom plate 11 and the top plate 13 to divide the installation tower 1 into a plurality of power generation layers.

In this embodiment, the bottom plate 11, the partition plate 12 and the top plate 13 are arranged in parallel, and the forward wind gathering device 3 and the reverse wind gathering device 4 also include an arc-shaped raised wind gathering plate 5 arranged on the bottom plate 11, the partition plate 12 and the top plate 13 facing the wind duct. Specifically, the shape of the arc-shaped raised wind gathering plate 5 in this embodiment is close to the curve shape of the inner wall of the side planing surface of the Venturi tube; in the inverted power generation layer formed by the top plate 13 and a partition plate 12, the top plate 13 and the partition plate 12 are both provided with an arc-shaped raised wind gathering plate 5. When the wind blows to the wind duct, it will be affected by the arc-shaped raised wind gathering plate 5 and gathered toward the center of the wind duct, so that the wind force reaching the vertical axis wind turbine 2 is gathered and strengthened above and below the wind duct, thereby realizing the horizontal wind gathering of the power generation layer.

As shown in FIG. 7 , in this embodiment, the vertical axis wind turbine 2 includes a wind wheel 21 and a generator 22 . The stator of the generator 22 is installed at the center of the power generation layer via a flange, and the wind wheel 21 is installed on the rotor of the generator 22 .

The wind wheel 21 is connected to the rotor of the generator 22 and rotates together, so that when the wind drives the wind wheel 21 to rotate, the generator 22 generates electricity. The stator of the generator 22 is installed at the center of the power generation layer through a flange, so that the wind gathering effect can be maximized. The impeller 21 can be a lift-type impeller (such as H-type, Φ-type impeller, spiral impeller), a resistance-type impeller (tulip-type impeller) or a combined impeller (resistance-type impeller + lift-type impeller). The impeller 21 of this embodiment is specifically a tulip-type impeller. The generator 22 can be a permanent magnet generator or an excitation generator. In this embodiment, it is specifically a permanent magnet generator. In order to make the tulip-type impeller more convenient to install, in this embodiment, two tulip-type wind blades are evenly fixed to the vertical hollow shaft through at least two support rods, and then the hollow shaft is connected to the rotor of the generator 22.

In this embodiment, an equipment layer 14 and several functional layers 15 are further provided under the base plate 11. The equipment layer 14 is a room made by utilizing the windless space on the lower floor, which is used to install the electric control/energy storage device of the generator. The electric control/energy storage device is electrically connected to the vertical axis wind turbine and is used to control the vertical axis wind turbine to generate electricity, rectify, stabilize voltage, store electric energy, invert, and output AC and DC power required by users. The remaining storage space of the equipment layer 14 can also be used to store tools and materials commonly used and necessary for life and work.

Among them, the functional layer 15 in this embodiment can be one to three layers, and the functional layer 15 can be used in charging parking lots, shopping malls, offices, factories and other places to create higher economic value by using self-sufficient clean energy.

In this embodiment, the bottom plate 11, the partition plate 12 and the top plate 13 are circular plates of the same area. Since the mounting tower 1 of this embodiment is cylindrical, the circular bottom plate 11, the partition plate 12 and the top plate 13 can better adapt to the mounting tower 1. At the same time, the circular bottom plate 11, the partition plate 12 and the top plate 13 can minimize the occupied area and can better gather wind from different directions, so that the power generation efficiency of the vertical axis wind turbine 2 is higher.

As shown in Figure 3, in this embodiment, the forward wind gathering device 3 includes a plurality of forward vertical wind gathering plates 31, and the forward vertical wind gathering plates 31 are vertically installed on the partition 12. The midpoint of the outer edge of the intersection surface of the forward vertical wind gathering plate 31 and the partition 12 is the first fulcrum, and the center line of the horizontal cross-section of the forward vertical wind gathering plate 31 along the length direction and the diameter of the partition 12 passing through the first fulcrum have an angle a in the forward rotation direction.

The positive vertical wind collecting plates 31 are vertically installed between the bottom plate 11 and the partition 12, or between the partition 12 and the partition 12, or between the partition 12 and the top plate 13, and include 3-12 positive vertical wind collecting plates 31. In this embodiment, 4 positive vertical wind collecting plates 31 are taken as an example for explanation. A gap of 1-30 mm is left between the inner side edge of the positive vertical wind collecting plates 31 (the end facing the vertical axis wind turbine 2) and the outer edge of the impeller 22 of the vertical axis wind turbine 2, so as to avoid the positive wind collecting plates 31 interfering with the rotation of the impeller 22. Since the positive vertical wind collecting plates 31 are deflected by an angle a toward the rotation direction of the impeller 22 of the vertical axis wind turbine 2, the wind blowing from different directions is all in the rotation direction of the impeller 22 when it reaches the impeller 22, thereby enhancing the rotation speed of the impeller 22, achieving a better wind collecting effect, and improving the power generation effect.

As shown in Figure 4, in this embodiment, the reverse wind gathering device 4 includes a plurality of reverse vertical wind gathering plates 41, which are vertically installed on the horizontal partition 12. The midpoint of the outer edge of the intersection surface of the reverse vertical wind gathering plate 41 and the partition 12 is the second fulcrum, and the center line of the horizontal cross-section of the reverse vertical wind gathering plate 41 along the length direction and the diameter of the partition 12 passing through the fulcrum have an angle in the reverse direction. The working principle of the reverse wind gathering device 4 is the same as that of the forward wind gathering device 3, which will not be repeated here.

In this embodiment, the cross-sections of the forward vertical wind gathering plates 31 and the reverse vertical wind gathering plates 41 are straight plate shapes as shown in Figures 3 and 4. In other embodiments, any other shapes that can change the airflow path can also be used, such as the streamlined shape shown in Figure 5, or the arc-edged triangle shown in Figure 6; the forward vertical wind gathering plates 31 and the reverse vertical wind gathering plates 41 can also be hollow or solid, and made of iron plates, aluminum plates, or composite materials (such as fiberglass).

In this embodiment, the arc-shaped raised wind collecting plates 5 of the bottom plate 11, the partition plate 12 and the top plate 13 intersect with the outer side surfaces of the positive vertical wind collecting plates 31 and the outer side surfaces of the reverse vertical wind collecting plates 41, so that the positive vertical wind collecting plates 31 and the reverse vertical wind collecting plates 41 are combined with the horizontal arc-shaped raised wind collecting plates 5 to form a complete wind collecting duct for the forward power generation layer and the reverse power generation layer, thereby maximizing the wind collecting effect.

In this embodiment, a photovoltaic panel is provided on the sun-facing surface of the partition 12, and solar photovoltaic panels are provided on the top plate 11 of the installation tower 1, the partitions 12 of each layer, the forward vertical wind concentrators 31, the reverse vertical wind concentrators/41, and the sun-facing surfaces of the outer walls of the equipment layer and the functional layer. The solar photovoltaic panels are electrically connected to the electronic control/energy storage device, thereby forming a tower-type wind-solar combined power generation system, which makes full use of natural clean energy and provides users with continuous and reliable AC/DC power supply in combination with the electronic control/energy storage device.

The tower power station using vertical axis wind turbines in the present embodiment adopts a multi-layer structure, occupies a small area, and makes full use of the vertical space. Each floor is equipped with a vertical vertical axis wind turbine, which can adapt to wind from all directions. The vertical axis wind turbines on each floor are reversed in turn, and wind is gathered by a forward wind gathering device and a reverse wind gathering device, respectively forming a good wind gathering effect for the forward and reverse vertical axis wind turbines, greatly improving the utilization rate of reverse wind and the breeze power generation of the vertical axis wind turbine, avoiding the tower body from bearing a unidirectional rotation torque, and improving the stability of the tower body. Solar photovoltaic panels are installed on the top plate 11 of the installation tower 1, the partitions 12 of each floor, the forward vertical wind gathering plates 31, the reverse vertical wind gathering plates 41, and the outer walls of the equipment layer and the functional layer facing the sun, forming a tower-type wind-gathering wind-solar combined power generation system.
