Description

TBEA's 100-megawatt-scale large-scale wind-solar hybrid desert grid-connected power station windproof wall

technical field

The utility model relates to a windproof wall of a power station, in particular to a windproof wall of a TBEA 100-megawatt-scale large-scale wind-solar complementary desert grid-connected power station, which belongs to the field of windproof walls of power stations.

Background technique

In the traditional sense of the photovoltaic power station, in order to more effectively protect the photovoltaic modules from being damaged by strong winds, and also to reduce the photovoltaic support and basic investment, try to avoid placing them in windy areas during the site selection stage. In our wind-solar hybrid project, we must Utilize high-efficiency solar energy resources, but also use high-quality wind resources. This is another inevitable contradiction. For better wind protection, the design service life of new energy projects is 25 years, which is less than the design service life of ordinary civil buildings.

Traditional windproof grids are mostly used in coal preparation plants for thermal power generation, and in the windproof design of high-speed railway lines. Since the design service life is not less than 50 years, the selected heavy-duty steel cross-section form is relatively economical and relatively economical. expensive.

In addition, in areas where wind erosion is relatively serious, many line poles are uneven by stones thrown by the wind, and some glass on the windward side of the wind farm is smashed by stones; It is made of stone, and its ability to resist stone blows is very weak.

Utility model content

In order to solve the above problems, the utility model designed a TBEA 100-megawatt-scale large-scale wind-solar complementary desert grid-connected power station windproof wall, which effectively reduces the wind speed and protects the battery components on site, that is, avoids the battery board being broken by the wind or The situation of blowing off also prevents the wind blowing stones from smashing the battery panels, which provides a reliable guarantee for the safe operation of the photovoltaic power plant.

The technical scheme of the utility model is:

The windproof wall of TBEA's 100-megawatt large-scale wind-solar hybrid desert grid-connected power station includes a windproof net frame, and a windproof net is arranged on the windproof net frame. The cross section of the windproof net frame is a right-angled trapezoidal structure, and the windproof net The frame is welded by steel pipes, and several horizontal beams are arranged inside the windproof grid frame, and inclined beams are connected between the horizontal beams to make the structure more firm.

Further, the steel pipe is Q23B thin-walled steel pipe, which reduces the cost.

Further, the height of the windproof net frame is 6000mm, the width of the lower bottom surface is 1200mm, and the width of the upper bottom surface is 350mm.

The utility model adopts the windproof net frame to realize the wind resistance. Since the control condition of most components is the stability control, the cross-sectional area of the components is not high, but the slenderness ratio of the rods is relatively high. Requirements, this provides the possibility to reduce the cost of construction. This project uses as much as possible to reduce the wall thickness, increase the radius of gyration of the section, and expand the section of the bar as much as possible, achieving good results, avoiding the traditional use of steel, but Thin-walled rods are used.

The utility model has the advantages of effectively reducing the wind speed and protecting the on-site battery components, that is, avoiding the situation that the battery board is broken or blown off by the wind, and also avoiding the wind blowing stones from smashing the battery board, which contributes to the safe operation of the photovoltaic power plant. Provides a reliable guarantee and reduces costs.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.
