Abstract
The utility model discloses a windproof and sandproof device for a solar power station, and the device, a ventilating structure, comprises a supporting frame and a base for arranging the supporting frame. The windproof and sandproof device for the solar power station is characterized in that a windproof and sandproof barrier surface is arranged on the supporting frame, the windproof and sandproof barrier surface comprises a plurality of sand resistance plates and wind resistance plates, and the wind resistance plate is uniformly provided with ventilation holes with different patterns and diameters according to various heights and wind regimes. By reducing the wind speed, the device prevents facilities in the solar power station from being damaged by a gale, the sand-carrying capability , the sand-carrying amount, and the transporting capability of the solar power station and the sand redistribution capability of the station are significantly reduced so that the sand redistribution capability around the power station, on solar battery panels, or on the surfaces of sunlight reflecting mirrors can be effectively prevented, and photoelectric conversion efficiency and photothermal conversion efficiency are free of influence.
Description
Technical field
The invention belongs to the environmental protection and energy saving field, be specifically related to a kind of checking the wind and fixing the shifting sand dirt device of solar power station.
Background technology
Enter 21st century, global economy has obtained the development of advancing by leaps and bounds, and various countries are multiplied to the demand of the energy.Solar energy is as the most basic on the earth, most important green novel energy source.Never depleted with it; Environmental protection; No waste gas trash discharge pollutes; Plurality of advantages such as the energy-conservation sustainable recycling life-span is long are developed rapidly and popularize.
But because the solar photoelectric light-heat product self is the reason that passive type is accepted and specific environment is installed, the photovoltaic generation of China mostly is selected in the northwestward that illumination condition is good, the land use expense is low, in the hope of the power benefit of maximum.The problem that but the west area mostly exists also, and wind is big, dust storm is big, dust is many.These sand and dust accumulate on the photovoltaic battery panel, have seriously influenced generating efficiency, and strong wind may cause the solar power station device damage simultaneously.Solar panel or heliostat are the core components of solar electrical energy generation, also are to be worth the highest part in the solar electrical energy generation.But polluted by natural environment, dust storm, dust, foreign material cover the unstable properties that cause on its surface, have a strong impact on the conversion efficiency of its photoelectricity, photo-thermal, during as strong wind even may damage solar panel or heliostat.
Strong wind is with dust storm and dust. and foreign material and some corrosive deposits blow off, be attached to solar panel or heliostat surface, as solar photovoltaic power plant, photoelectric conversion rate is generally 12 left and right sides %, test according to incompletely statistics, and the dust foreign material adhere to its surperficial 3-5 and did not clean in individual month, conversion efficiency just reduces about 9% on original basis, to have a strong impact on its photoelectricity. the conversion efficiency of photo-thermal reduce its functional performance, even damage brings about great losses.
Solar power station does not have wind-proof device at present, and the main prophylactico-therapeutic measures that influenced by dust storm and airborne dust mainly is artificial cleaning: organize regularly manually solar panel or heliostat surface are regularly cleaned.But above-mentioned measure one is to need a large amount of manpowers, the 2nd, and the cleaning frequency height, the 3rd, many places, large-sized solar power station are in the northwest open field, and dust storm is big, and no water source can't often in time clean performance difficulty again.
Solar panel and mirror reflective plate reduce its functional performance because surperficial sand and dust adhere to the conversion efficiency that ghost image rings its photoelectricity, photo-thermal, and strong wind may cause the solar electrical energy generation facility to damage simultaneously.This project is by windproof depositing dust, reduces above-mentioned influence, improves its generating efficiency, saves simultaneously because of the artificial water resource that consumes of cleaning.
Summary of the invention
Purpose of the present invention is intended to overcome above-mentioned shortcoming, a kind of device of simple in structure, economical and practical solar power station checking the wind and fixing the shifting sand dirt is provided, by windproof depositing dust, reduce above-mentioned influence, improve generating efficiency and the application life of solar power station, reduce the regular maintenance expense, save simultaneously because of the artificial water resource that consumes of cleaning.
For achieving the above object, the present invention adopts following solution: the checking the wind and fixing the shifting sand dirt device that certain altitude is set around solar power station, when strong wind passes through, reduce the wind speed of wind, make it take the sand and dust ability, take sand dust, transporting capacity and the reallocation ability of sand and dust descended significantly, effectively reduce strong wind and sand and dust to the influence of solar power station.
A kind of device of solar power station checking the wind and fixing the shifting sand dirt is arranged on around the solar power station.Highly be 2 meters-50 meters, it is made up of basis, bracing frame and checking the wind and fixing the shifting sand barrier face, and checking the wind and fixing the shifting sand barrier face is ventilation structure.Checking the wind and fixing the shifting sand barrier face is by the sand-proof net sheet and press down aerofoil and forms, sand-proof net sheet and press down aerofoil and be fixedly mounted on the bracing frame, but aerofoil is evenly equipped with gravity vent, and the ventilation porosity is 10%-90%.
The pass of described gravity vent is circular hole, square hole, slotted hole, oblong aperture, delthyrium, diamond hole and combination thereof, and the gravity vent in different passes, different apertures is set according to differing heights, different wind regime.
Principle of the present invention is: this device reduces wind speed by the kinetic energy of checking the wind and fixing the shifting sand barrier face decay incoming flow wind, prevents that strong wind from causing damage to the solar power station facility.Reduce wind speed simultaneously, make it take the sand and dust ability, take sand dust, transporting capacity and the reallocation ability of sand and dust reduced significantly, spread with the wind, descend slowly and lightly on solar panel or heliostat surface thereby effectively prevented and treated solar power station periphery sand and dust, dust etc., influence the conversion efficiency of its photoelectricity, photo-thermal.
Compared with prior art, the present invention has following advantage:
The present invention can reduce wind speed, prevents that strong wind from damaging the solar power station facility, filled up the blank that present solar power station does not have protection from the wind.And by reducing wind speed, make it take the sand and dust ability, take sand dust, transporting capacity and the reallocation ability of sand and dust descended significantly, spread with the wind, descend slowly and lightly on solar panel or heliostat surface thereby effectively prevented and treated power station periphery sand and dust, dust etc., influence the conversion efficiency of its photoelectricity, photo-thermal.
