Description
Technical field
The present invention relates to a kind of buoyancy aid waterborne, particularly relate to a kind of photovoltaic plant buoyancy aid waterborne and attaching method thereof.
Background technology
Along with the exhaustion day by day of the non-renewable energy resources such as oil gas, the development and application of the mankind to regenerative resource is more and more paid attention to, solar energy has become the pith in the regenerative resource of mankind's use, is that a kind of very desirable new forms of energy also wish further to be developed.
Photovoltaic generation utilizes the photovoltaic effect of interface and directly changes luminous energy into electric energy.Photovoltaic plant has without the need to consume fuel, safe and reliable, the advantage such as noiseless, non-pollution discharge, construction period are short.But photo-voltaic power generation station not only floor space is large, and can change character and the attribute in soil.Therefore, but area that land surface less sufficient for sunshine, photovoltaic plant waterborne becomes a new selection.But the construction technique waterborne of photovoltaic plant is also immature, to the structure of photovoltaic plant buoyancy aid, be that the pattern of reference ground or roof photovoltaic power station carries out design and establishing mostly.
As, CN204349861U discloses the floating module of a kind of photovoltaic waterborne, as shown in Figure 1, mainly comprises floating carrier 1, bearing support 2, coupling assembling 3, photovoltaic module 4 and is connected inserted block 5.Floating carrier 1 swims on the water surface, and coupling assembling 3 is arranged in the installing hole of floating carrier 1, and bearing support 2 and coupling assembling 3 are interconnected by pin, and photovoltaic module 4 is fixed on bearing support.This module can float on separately the water surface for generating, also can be interconnected for setting up photovoltaic plant waterborne.But when adopting this floating module to build, need the height first adjusting each assembly, then each assembly is connected as one, and then lay photovoltaic module, build difficulty comparatively greatly, build cost higher, consuming time longer, and regular maintenance is not easily.
In addition, the floating module of above-mentioned photovoltaic, due between adjacent floating carrier by the shrinkage pool that is arranged at its side be connected cooperatively interacting of inserted block and connect as one, the difficulty of processing of the floating carrier of this structure is large, cost is higher, and its opposing water impact is limited in one's ability, when water impact is larger, easily come off or wear and tear between shrinkage pool and connection inserted block, be not suitable for large-area promoting the use of.
And for example, CN204290836U discloses a kind of floating carrier, as shown in Figure 2, comprise the buoyant member 1 and mounting bracket 2 that are mutually connected, described buoyant member 1 is tower structure, wherein, the rectangular frame-structure that described buoyant member 1 is formed in one, and the material of described buoyant member 1 and described mounting bracket 2 is the fiberglass in nonmetal-nonmetallic composite.In order to adapt to the installation needs of solar cell, the installed surface of described mounting bracket 2 and horizontal plane angle be 15 °, described mounting bracket 2 specifically comprises four root posts 21 be connected with four angles of described buoyant member 1, and described column 21 is divided into highly different two groups, two that are wherein positioned at diagonal positions highly different; The top of adjacent two highly different described columns 21 is connected by brace summer 22, and is provided with the mounting rail 23 of three position-adjustable between be parallel to each other two described brace summers 22.Said structure of the present utility model solves the nonadjustable problem in floating carrier angle of inclination, but the floating carrier of said structure, manufactures, installs inconvenience, and is unfavorable for and connection around between buoyancy aid or connector.Meanwhile, because buoyancy aid is large area hollow structure, top is nonmetal frame structure, and cost is higher, and the stability of structural entity is bad, poor to the resistance of water impact.
Two kinds of above-mentioned structures, when connecting between buoyancy aid, all do not arrange gap between buoyancy aid, the radiating effect of heating panel is poor, and the radiating efficiency of heating panel is lower.
Because the geographical environment of different regions is different, water impact dynamics is different, and be also not quite similar to the requirement of photovoltaic plant buoyancy aid, obviously, above-mentioned buoyancy aid cannot meet the demand of photovoltaic plant development.
Therefore, those skilled in the art need badly research a kind of simple to operate, cost is low, adaptable photovoltaic plant buoyancy aid waterborne.
