Detailed Description
The invention is described in further detail below with reference to the accompanying drawings:
example one
Referring to the attached figure 1, the sand-fixing greening method mainly comprises the following steps:
and (I) arranging a sand-proof wall. The sand-proof wall is mainly used for blocking sand and stones, and the height of the sand-proof wall is not required to be very high in desert edge areas. Certainly, the wind power on the leeward side can be reduced, and a certain protection effect is achieved on the sand fixation greening area.
And (II) planning a forest area, a grassland and a wind-solar hybrid power station in sequence on the lee side of the sand-proof wall.
By the arrangement, the forest, the grassland and the wind-solar hybrid power station are not affected, and after afforestation is successful, the forest can further weaken wind power and protect the grassland and the solar power station.
Water conduit systems with irrigation, drip irrigation and cooling functions are respectively arranged in forest areas, grasslands and wind-solar hybrid power stations so as to meet the water supply requirements for sand fixation and greening.
Preferably, the grassland and the forest area are arranged around the power station.
And thirdly, building the wind-solar hybrid power station with reference to the attached figure 2.
3.1, arranging a plurality of reinforcing steel bars 1 in a cross mode, and dividing a matrix type solar power generation module installation area on the ground.
The steel bar 1 can be replaced by angle steel or high polymer rigid material. The number and the longitudinal length of the steel bars 1 are determined according to the specific needs of the power station, and the single steel bars can be spliced by welding obviously.
3.2, burying the ground pile at the position A where the steel bars 1 are crossed with each other. The ground pile is cast by steel drill (ground anchor) or concrete, and the steel bar 1 and the ground pile are integrated into a whole by a fixing means.
3.3, arranging the wind power generation module fixing base 2 close to the ground pile or integrating the wind power generation module fixing base with the ground pile into a whole. Preferably, the wind power generation module fixing base is disposed at a position where the reinforcing bars 1 cross each other, and is integrally formed with the reinforcing bars 1, for example, by concrete casting or the like.
Through the steps, all the ground piles and the wind power generation module fixing bases 2 which are arranged in a dot matrix mode in the power station are connected together through the crossed steel bar network to form a stable foundation structure.
In step 3.1, as shown in fig. 2, a plurality of closed or semi-open solar power generation module installation areas are formed in the power plant foundation structure, and a plurality of solar power generation units are installed in each solar power generation module installation area in an aligned manner. Specifically, referring to fig. 4, the solar power generation units are fixed in the solar power generation module installation area in an orderly arrangement manner through the brackets, the brackets are connected in series/parallel through the solar power generation unit locking members 3, and finally, the solar power generation unit locking members 3 are fixedly connected with the steel bars 1.
In step 3.2, the wind power tower is further mounted on the wind power generation module fixing base 2. The height of the sand prevention wall is lower than that of the wind power generation tower.
Example two
In order to further increase the strength of the foundation structure of the power station, at least two steel bars 1 are selected as a group in step 3.1 of the first embodiment, see the solid lines and the dotted lines shown in fig. 3, and ground piles are buried at the positions B where the steel bars 1 cross each other.
As a further preferable means, the pavement C is laid on the longitudinal direction of the at least two reinforcing bars 1 such that the at least two reinforcing bars 1 form a whole, such as a reinforced concrete pavement or a conventional asphalt pavement. The pavement C provides traffic in the power station and further reinforces the foundation structure.
(IV) in all embodiments of the invention, it may be optional to dig wells in any or all of the solar module installation areas. The power station is used for pumping underground water and supplying water to grasslands and forest areas through a water diversion pipeline system. The cooling water pipeline in the solar power station can cool the components needing cooling, such as a generator, a photovoltaic panel and the like.
Of course, the wells may be located in other areas.
The invention provides a feasible sand-fixing greening scheme. When a certain area is greened, a self-sustainable ecological system is formed. The sand-fixing greening scheme of the invention is adopted step by step, and desertification can be rapidly and effectively controlled.
In the sand-fixing greening scheme, the invention also provides an excellent overall power generation equipment foundation structure, which is particularly suitable for building wind-solar complementary power stations in deserts and gobi edge areas. Electric energy generated by wind power and solar energy is connected to the grid by adopting a power electronic converter, basic energy is provided for operation, control and maintenance of power equipment in the station, and redundant electric power is stored by a storage battery or is transmitted to a human living area to be merged into a public power grid or is subjected to sand fixation and greening. The deep well for irrigation is arranged in the station, the cooling water for the operation of the power station is provided by utilizing the power in the station, the heat energy is collected, and in addition, the domestic water for the working personnel can be provided.
