Description
Technical field
The utility model relates to photovoltaic power generation technology, and more particularly it is offshore water surface photovoltaic power station buoyant foundation anchor fitting.
Background technology
Large-scale ground formula photovoltaic plant generally builds or rise and fall little on-site smooth in physical features, selects corresponding basis and rack form according to geological condition in field.But along with domestic usable land resource scarcity and land transformation difficulty increase, construction place area simultaneously due to photovoltaic plant needs is larger, the cost of land photovoltaic construction increases day by day, entire society's benefit day by day reduces, and south China area water surface area is extensive, and most of water surface is in idle, therefore photovoltaic builds the water-surface areas development such as place starts to reservoir, lake beach and fish pond, but present stage or mainly adopt the pipe pile foundation similar with common ground photovoltaic plant.The bottom is imbedded on this basis, and top road goes out the water surface for fixed light photovoltaic assembly.But adopt this kind of basis to reduce due to the highly excessive stability that causes, waters part photovoltaic module capital construction difficulty simultaneously, to necessarily adjust in the form of the region base of different latitude, be unfavorable for the construction of water surface photovoltaic power station modularization, be only applicable to the water level such as beach, fish pond relatively shallowly district, for not concrete feasibility such as lake surface, reservoir etc. that change of level is larger, therefore this form basis does not possess the condition of large-scale application.Water surface floating photovoltaic plant can be implemented in the photovoltaic plant exploitation in different latitude, dissimilar waters, greatly improve the economic and social benefit of photovoltaic plant, but in most of waters, change of level is obvious, existing anchorage technology or high cost, the rotation of surface components cannot be avoided, cause component efficiency lower.This anchorage technology is applicable to the fixing, with low cost of offshore water surface floating photovoltaic plant, and substantially can not produce rotation, is applicable to and all kinds of waters.
Summary of the invention
The offshore water surface photovoltaic power station buoyant foundation anchor fitting that the purpose of this utility model is to overcome existing anchor fitting poor stability and provides.
The utility model realizes by following technical scheme:
Offshore water surface photovoltaic power station buoyant foundation anchor fitting, comprises the embankment of water body, described embankment is provided with guide rail; A pair floating drum is symmetrically arranged with in described guide rail; Connected by axle between two floating drums; Described axle runs through described floating drum; Described axle to be rolled with described guide rail by bearing and coordinates;
Be provided with in the middle part of described axle and be also connected with the hollow collar; The described hollow collar is connected with floating type photovoltaic module by pipe link;
Be provided with center projections in the middle part of described axle, described hollow collar internal diameter is greater than described center projections external diameter, and described hollow sleeve ring width is less than described center projections width.
Described pipe link comprises knuckle, and described knuckle angle is identical with the angle of described guide rail and horizontal surface.
In the utility model, bank is arranged guide rail, and upper surface is semiclosed, and current can be allowed to free in and out and fix floating drum; The fixed end of anchoring is the floating drum in track, and it is highly consistent is consistent with water level, the stress and displacement of minimizing buoyant foundation; Floating drum two ends are provided with bearing, make floating drum easier to be current in track to reduce friction.The utility model is applicable to for the harsher photovoltaic plant of anglec of rotation restriction ratio.Compared with common anchorage technology, can reduce stressed, automatically regulate height according to water level, whole floating body displacement is few, and the anglec of rotation reduces greatly.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but this embodiment should not be construed restriction of the present utility model, only for example, simultaneously by illustrating that advantage of the present utility model will become clearly and easy understand.
As described in Figure, the utility model comprises along being provided with floating drum 2 in the fixing guide rail 1 of embankment 0, bearing 3 can be rolled in guide rail 1 with change of level after being connected by axle 4; Connected by axle 4 between two floating drums 2; Axle 4 runs through floating drum 2; Axle 4 is rolled with guide rail 1 by bearing 3 and coordinates; Floating drum 2 is connected with floating type photovoltaic module 7 by the pipe link 5 of rigidity.Guide rail 1 upper surface is semiclosed form, and central authorities leave gap to make current to free in and out and can fix floating drum 2 simultaneously.Floating drum 2 is made by the plastic material that density is less, and there is a cylindrical inner diameter inside, surrounds air form floating drum by inside face, outside face; Bearing 3 internal diameter is identical with the internal diameter of floating drum 2.Axle 4 central part protruding, diameter is slightly larger than two ends, and for being connected with pipe link 5, there is screw thread at two ends, for by the fixing floating drum 2 of nut and bearing 3.Pipe link 5 is rigid, and the one end be connected with floating drum is a hollow collar 6; The other end is connected with floating type photovoltaic module 7.During use, the hollow collar 6 is positioned at the center projections position of axle 4, and floating drum 2, bearing 3 symmetry are positioned at the hollow collar 6 both sides, are then fixed by nut.The hollow collar 6 internal diameter, slightly larger than the external diameter of axle 4 center projections 41, makes pipe link 5 move within the specific limits, so that less interaction force; The hollow collar 6 thickness is slightly less than axle 4 center projections 41 thickness, and the side surface of the hollow collar 6 is not rubbed with miscellaneous part.Pipe link 5 has knuckle 51 with a certain distance from the hollow collar 6 position, the angle between the guide rail 1 that its size equals and horizontal surface.Angle makes floating drum 2 be subject to the application force of floating type photovoltaic module 7 all the time along guide rail direction, to reduce friction force.
The utility model offshore water surface photovoltaic power station buoyant foundation anchor fitting, comprises following features: one, guide rail is arranged along bank, and upper surface is semi-enclosed, allows current to free in and out and limits floating drum disengaging; Two, anchored end is positioned on water line all the time, can not produce upwards or downward pulling force makes buoyant foundation tilt to buoyant foundation; Three, between floating drum and buoyant foundation for being rigidly connected, can collision free and can rotation be reduced to a certain extent, increase photovoltaic module efficiency; Four, floating drum two ends are provided with bearing, to reduce the friction force of floating drum in guide rail; Five, have certain knuckle between rigid link and floating drum, the interaction force making floating drum be subject to buoyant foundation is avoided stuck along guide rail direction all the time.
It should be noted that: to those of ordinary skill in the art, can also make some changes or distortion to the utility model under the prerequisite not changing the utility model principle, this belongs to protection domain of the present utility model equally.
