Description
Technical field
This utility model relevant photovoltaic power generation equipment field, a kind of photovoltaic power generation apparatus arranged on the water surface.
Background technology
At present major part photovoltaic plant construction is in relatively flat land, but along with the smooth place that can be used for building extensive ground photovoltaic plant is fewer and feweri, photovoltaic gradually to mountain region, the direction such as roof, the water surface develops.For water surface photovoltaic power station, classify two kinds, a kind of for bracket basis is directly taken root in the bottom, another kind of for swimming on the water surface.
Take root and the most substantially continue to use the technology of ground light overhead utility in water-bed advantage, relatively costly based on shortcoming, and it is not suitable for deeper waters.And floatation type photovoltaic avoids above-mentioned shortcoming, decrease the quantities on basis, do not affected by the depth of water simultaneously.
The fairly large floatation type photovoltaic plant built up at present, the most fixed, track of sun is not tracked.
Utility model content
This utility model is solved the technical problem that to be, uses less cost to realize floating type water photovoltaic tracking system, to improve the generated energy of floating type water photovoltaic.
The technological means that this utility model is used is as described below.
A kind of floating photovoltaic tracking device of thrust by airscrew, comprises buoyancy aid, this buoyancy aid arranges some solar panels, forms floating photovoltaic cells, arrange some screw propellers bottom buoyancy aid, and this screw propeller connects control device, is controlled by controlling device.
This screw propeller has blade, and this blade can be with forward and reverse rotation.
Also setting up But rotary joint bottom this buoyancy aid, this But rotary joint connects fixing device by chain, and this fixing device connects the bottom.
This screw propeller is arranged on peripheral rim portion bottom buoyancy aid, and is uniformly distributed.
This buoyancy aid is circular or oval.
The machinery passing through to change solar panels inclination angle between this solar panels with buoyancy aid is connected.
One corral gear is set outside this buoyancy aid.
Floating photovoltaic cells is made up of some floating photovoltaic subelements, and floating photovoltaic subelement arranges some solar panels, and solar panels combination forms floating photovoltaic subelement array
Have the beneficial effect that produced by this utility model.
1. improving generated energy: the most economical embodiment of native system is vertical axle tracing system, generated energy is higher than fixed and flat single-shaft tracking system.
2. system cost is low: native system only adds screw propeller on the basis of original floatation type photovoltaic plant and control system i.e. realizes following the tracks of, it is achieved the cost of this system is relatively low.In the case of limited fund, fixing connected mode typically can be used to connect solar panels and buoyancy aid, now control solar panels direction merely with screw propeller, form vertical axle tracing system.
3. there is further room for promotion: under conditions of investment allows, a set of machinery can be increased on the basis of native system, changing over the inclination angle of photovoltaic module, thus the vertical axis tracking mode of native system is upgraded to double-axis tracking mode, this is the embodiment that generated energy is the highest.
4, having certain thrust due to screw propeller, it goes for all water surface substantially.

Detailed description of the invention
As Figure 1-5, a kind of floating photovoltaic tracking device of thrust by airscrew, comprise buoyancy aid 1, arrange on this buoyancy aid 1 and formed floating photovoltaic cells 10 by some solar panels 2, arranging some screw propellers 4 bottom buoyancy aid 1, this screw propeller 4 connects control device, is controlled by controlling device.Here screw propeller is exactly general screw propellor for boat structure, and it can arrange some buoyancy aids and use on a piece of waters, and waters here is selected and do not limited, and all waters can be suitable for substantially.Screw propeller tangential direction circumferentially is installed, and propeller can use electrical energy drive.Screw propeller is controlled by unified control system.The quantity of screw propeller and power determine after considering calculating according to size, weight, power demand and the water body environment of actual floatation type photovoltaic cells.
This utility model belongs to vertical axis rotation tracking system, and tracking mode is the azimuthal variation that sun every day is followed the tracks of in the horizontal rotation of whole floating photovoltaic cells.During morning, whole photovoltaic system is towards in the east, elapse in time, solar azimuth changes from east orientation west, system of now following the tracks of measures the azimuth of current floating photovoltaic cells by Instrument sensor (such as gyroscope or other instruments), simultaneously calculate required rotation amount according to the time m-azimuth corresponding relation set in program, the multiple screw propeller action of control system Collaborative Control, promotes floating photovoltaic cells to rotate.Control system can calculate the inertia of rotation in conjunction with the factor such as water velocity and own wt, when judging that floating photovoltaic cells azimuth can meet demand, stops screw propeller, and the rotary impetus of the most floating photovoltaic cells disappears.Screw propeller can forward and reverse rotation, can position and azimuth to floating photovoltaic cells be adjusted flexibly.Tracking to the sun in evening by this control system set, whole photovoltaic system is towards west.Now control system reverse operating, propeller reversely rotates so that floating photovoltaic cells rotates from West to East, rotates to whole photovoltaic system towards east state, waits that second day sun rises.Owing to floating photovoltaic cells only carries out the most about 180 ° rotate forward and the reverse rotation of once same angle in one day, slowly, therefore its power demand is the biggest in whole spinning movement.
Also setting up But rotary joint 5 bottom this buoyancy aid 1, this But rotary joint 5 connects fixing device 7 by chain 6, and this fixing device 7 connects the bottom.This But rotary joint general is arranged on buoyancy aid centre position, and chain can be cable wire or iron chains, and does waterproof, preservative treatment.Fixing device is generally stake or weight (being similar to ship anchor).
Buoyancy aid 1 can be typically sub-circular, ellipsoidal structure, and this screw propeller 4 is arranged on peripheral rim portion bottom buoyancy aid, and is uniformly distributed.
In the case of in the money, the machinery 8 passing through to change solar panels inclination angle between this solar panels 2 with buoyancy aid 1 is connected.Change over the inclination angle of photovoltaic module and solar panels, thus vertical axis tracking mode of the present utility model is upgraded to double-axis tracking mode.This machinery is that those skilled in the art can realize.In the case of limited fund, fixing connected mode typically can be used to connect solar panels and buoyancy aid, now control solar panels direction merely with screw propeller, form vertical axle tracing system.
One corral gear can be set outside this buoyancy aid 1, ensure the steady of the internal waters of floating photovoltaic cells, it is to avoid current produce the revolving force that some are extra as far as possible.
Floating photovoltaic cells 10 can be made up of some floating photovoltaic subelement 9 as shown in Figure 4, and this floating photovoltaic subelement 9 arranges some solar panels 2, and solar panels combination forms floating photovoltaic subelement array 3 as shown in Figure 5.
