Description
Technical Field
The invention relates to the technical field of energy storage, in particular to an energy storage wind tower.
Background
With the increasing prominence of global energy shortage, serious environmental pollution, climate change and other problems, the power industry is gradually changed from traditional coal power generation and petroleum power generation to new energy power generation, and in various new energy technologies, wind power generation has been developed across due to the advantages of the most mature technology, the most commercialized prospect and the like. Wind power is recognized as one of the best schemes for solving the problems of energy shortage, environmental pollution, climate change and the like, but the traditional wind power also has some disadvantages that firstly, the service life of the glass fiber reinforced plastic fan blade is short and the pollution after the waste is large; secondly, the wind blades are too heavy to enlarge the wind catching area; thirdly, the fan blade is extremely long and difficult to transport, and the transport cost is extremely high; fourthly, the power generation speed-up gear box is difficult to maintain and is easy to discard; fifthly, the power generation is limited by wind resources, and the requirements of the power grid cannot be met, so that the wind is frequently abandoned. In particular, the fifth point is a fatal disadvantage of wind power generation, namely, the fluctuation of wind resources, which leads to instability of the active output of the wind farm. With the continuous expansion of the scale of wind power stations and the increase of wind power penetration rate, high-capacity wind power access also brings a plurality of challenges to power grid dispatching and stable operation. One of the feasible methods for solving the problem is to adopt an energy storage technology to realize flexible adjustment of the active power of the wind turbine generator.
Among various energy storage technologies, the water storage energy storage technology is one of the most widely used at present, and can be used for lifting water from a low place to a high place through consuming electric energy when the electric quantity is sufficient, so that the electric energy is converted into potential energy of the water, and the potential energy of the water is converted into the electric energy through water descending when the electric quantity of a power grid is insufficient. At present, a lot of technical schemes for combining a wind power generation system with a water storage and energy storage system exist, for example, a wind power combined hydroelectric generation device disclosed in CN102635480A is used for driving a water pump to pump circulating liquid to a high place by using an impeller driven by wind power, and then the circulating liquid is discharged downwards, so that the circulating liquid impacts a rotating wheel of a hydro-generator, and further the effect of generating power is achieved. For example, CN103410651a discloses a hydroelectric device for pumping water and storing energy by using offshore wind power, which comprises a wind turbine, an energy storage ball, a water pump and a hydroelectric device; the wind power generation device is characterized in that the wind power machine is built above the sea level, the energy storage ball is built on the seabed below the sea level, a seawater inlet is formed in the energy storage ball, a hydroelectric generator is arranged at the water inlet to generate electricity, and the water pump can discharge seawater in the energy storage ball after impacting the hydroelectric generator to generate electricity into the sea. The technical scheme that wind power and water storage and energy storage are combined realizes the combination of wind power generation and water storage and energy storage technologies, and can really solve the problem of unstable wind power generation output. However, in these schemes, the functions of the combined system are relatively simple, namely, the combined system can only store the surplus wind power into the potential energy of water, and the potential energy of water is required to be converted into electric energy for people to use later.
In view of this, this application aims at providing an energy storage wind tower, and this energy storage wind tower has more functions, for example on the basis of realizing energy storage function, can also directly provide the domestic water of different temperatures for people.

Furthermore, when the electric energy of the external power grid is insufficient, the energy storage wind tower can simultaneously supply power to the power grid by generating power and converting the water vapor.

The tower is also provided with an air compression device, and when no power is supplied to the outside, the power generated by the wind generating set can be used for driving the air compressor to compress water vapor or air and store the water vapor or air in the pipeline. The tower is provided with an air power generation device (such as a turbo generator) which converts stored compressed air into electric energy when external power supply is required.
Furthermore, the wind power blade is made of metal and glass, and has extremely long service life and zero pollution.
Furthermore, the wind power blade has the structure that steel pipe trusses are added with steel ropes, the weight is obviously reduced, the wind capturing area is enlarged, and conditions are created for wind power related facilities without going up mountain and down sea.

Detailed Description

Example 1
As shown in fig. 1-3, the embodiment is an energy storage wind tower, which comprises wind power blades 1, a power generation part 2 and a tower, wherein the tower comprises a pipeline 33, and water is stored in the pipeline 3 of the tower; when the energy storage wind tower does not supply power to the outside, the electricity generated by the wind tower can be used for changing the temperature of water. The power generation part 2 mainly comprises a wind generating set, a water suction pump, a hydraulic generator, a heater, a water chiller, a steam turbine generator set and other devices.
In this embodiment, 4 pipes 3 form the lower structure of the tower, and a plurality of connecting rods are arranged between adjacent pipes. The upper structure of the tower is then a truss structure 4. Above the truss structure 4 are mounted wind power blades 1 and a power generation section 2. The truss structure 4 is formed by welding cross bars 42, vertical bars 41 and diagonal bars 43. A support seat 411 is arranged on the vertical rod 41, and the support seat 411 is used for being connected with the cross rod 42 or the inclined rod 43 in a threaded manner. The inside of the vertical rod 41 is provided with a ring rib 412 near the supporting seat 411, and the ring rib 412 is used for increasing the strength of the vertical rod 41 at the position of the supporting seat 411.
In this embodiment, the internal cavity of the duct 3 may be divided into several sections by partitions, and the space of each section may be used for storing water vapor, high temperature water or low temperature water, respectively. Thus, high-temperature water and low-temperature water can be simultaneously provided, and the service quality of the wind tower is improved.
The energy storage wind tower in the embodiment is connected with an external power grid, and when the electric energy of the external power grid is excessive, the energy storage wind tower can absorb the external electric energy so as to be used for improving water temperature and the like.
The use process of the embodiment is as follows: when the wind tower does not need to supply power to the outside, the electric energy generated by the wind generating set heats water in certain section spaces of the pipeline 3 into high-temperature high-pressure steam and stores the high-temperature high-pressure steam, and when the power is needed to be supplied, the high-temperature steam is converted into electric energy through the steam turbine generator set, so that the energy storage function is realized. When the electric energy of the external power grid is insufficient, the energy storage wind tower can generate electricity and the electric energy converted by the water vapor can supply power to the power grid at the same time.
