Description
Technical field
The utility model is related to technical field of photovoltaic power generation, and in particular to a kind of photovoltaic bracket basis.
Background technology
Photovoltaic bracket basis is mainly used in installing, supports photovoltaic bracket and solar cell module.Photovoltaic bracket basis
Design will fully take into account the factors such as load-bearing, wind resistance, antidetonation.
At present, photovoltaic bracket foundation main will include isolated footing, strip footing, prefabricated pile basis, bored concrete pile foundation, spiral
Pile foundation etc..For the extreme terrain geomorphological structure of desert area, when carrying out the design selection on photovoltaic power plant bracket basis, greatly
Majority uses bored concrete pile foundation.
In desert area, the dust storm of photovoltaic plant place be lost in it is more serious because dust storm is than larger throughout the year, sand sometimes
Photovoltaic module can be buried, the partial denudation that photovoltaic bracket basis can be eroded and cause its original to be located under earth's surface sometimes exists
Outside, load-bearing and wind loading rating that now can be to photovoltaic bracket basis have a negative impact, so as to influence the matter of whole photovoltaic plant
Amount.
Specifically, the structure of existing bored concrete pile foundation is as shown in Figure 1.After strong wind runs into bored concrete pile 1, strong wind can be round filling
Note stake 1 and produce whirlwind, after being eroded by a period of time, the earth's surface around bored concrete pile 1 just occurs that swirl shape is recessed, so that
Originally be located at earth's surface under bored concrete pile foundation it is naked be exposed on the external, and then reduce bored concrete pile foundation bearing capacity and wind resistance power.
In order to solve the above problems, generally checked winds and fixed drifting sand at present using following two modes：
1) windbreak method.
Windbreak is set up in photovoltaic place periphery, wind erosion of the strong wind to photovoltaic plant place is prevented by windbreak, is lacked
Point is construction cost than larger, and is not very big to the wind erosion barrier effect on photovoltaic bracket basis.
2) straw checkerboard barrier sand-protecting barrier fixes the sand method.
Long stalk etc. is embedded in grid prefabricated in advance in photovoltaic place periphery and fixed the sand, has the disadvantage that straw etc. is similar
Thing easily, it is necessary to often safeguard, and cost is than larger, typically in a photovoltaic plant surrounding using straw checkerboard barrier fixed the sand method by corruption
Costs up to a million or even up to ten million are then needed, while the dust storm loss to place inside bracket basis does not have good work yet
With.
It can be seen that, design it is a kind of can reduce because dust storm corrodes and to the injury caused by photovoltaic bracket basis and with low cost
Scheme of checking winds and fixing drifting sand turn into technical problem urgently to be resolved hurrily at present.
