Description
Technical field
The present invention relates to photovoltaic plant field, particularly relate to a kind of photovoltaic power station component automatic temp. reducing device.
Background technology
Energy shortage and environmental conservation are the common issue of facing mankind.For the mankind of 21 century, sunlight as a kind of can infinitely utilizing, the novel renewable energy of environmental protection, itself be exactly wealth.Under the background that global energy is in short supply, the status of the regenerative resources such as solar energy is more and more important.
The core cell of photovoltaic generation is solar module at present, and research shows, when silicon solar cell is operated in higher temperature, open-circuit voltage declines to a great extent with the rising of temperature, also results in the serious skew of charging operating point, easily makes system undercharge damage；The output of silicon solar cell also declines to a great extent with the rising of temperature, causes solar module can not play maximum performance.
Summary of the invention
Goal of the invention: it is an object of the invention to overcome the deficiencies in the prior art to provide a kind of device that the rainwater collected down cycles automatic to photovoltaic power station component can be utilized to utilize.
Technical scheme: photovoltaic power station component automatic temp. reducing device of the present invention, including rain collecting system, circulation temperature lowering system and automatic valve；The rainwater collected is sent into circulation temperature lowering system by automatic valve by rain collecting system；
Rain collecting system includes that branch gathers rain pipe, main rainwater collection collector, communicating pipe and cistern；Branch gathers and connects main rainwater collection collector bottom rain pipe；Cistern water inlet is connected by communicating pipe bottom main rainwater collection collector；Cistern outlet goes out to connect automatic valve；
Circulation temperature lowering system includes high-pressure pump, condenser and heat sink；Automatic valve is connected with high-pressure pump and condenser respectively by Y type water pipe, and high-pressure pump is connected with heat sink top and bottom mating respectively with condenser；Heat sink is disposed adjacent with photovoltaic battery panel coupling.
Branch gathers roof terminal and arranges three-dimensional coarse strainer.
Arranging supersonic liquid level induction apparatus in the middle part of main rainwater collection collector, bottom arranges time control valve.
Supersonic liquid level sensor location is less than cistern water inlet.
Condenser is water condenser or aerial condenser.
Cistern is connected with service water pipeline.
The operation principle of the present invention: during rainfall, rainwater is collected to branch through assembly surface and gathers rain pipe, filter out the bulks such as the leaves in water, architect shatter through three-dimensional coarse strainer to mince and be pooled to main rainwater collection collector the most again, the most serious early-stage rainwater of dirt initially enters in main rainwater collection collector, when supersonic liquid level induction apparatus senses that rainwater increases, time control valve will be opened by automatic linkage device automatically, the most serious rainwater of initial stage dirt will be discharged, and discharges rainfall and the time can be arranged according to local rainwater strength formula and factory roof areal calculation.After early-stage rainwater is discharged, automatic valve is then automatically switched off, then rainwater will be by main rainwater collection collector with overflow to communicating pipe in cistern, rainwater is opened automatic valve after precipitation and by high-pressure pump, water is squeezed into heat sink photovoltaic battery panel is carried out cooling process, water by heat sink, photovoltaic electrification component is lowered the temperature after entrance condenser carry out heat exchange after enter back into high-pressure pump recycling photovoltaic electrification component lowered the temperature.
Beneficial effect: 1, the present invention utilizes the rainwater collected as cooling water, cycle refrigeration system is entered by automatic valve, flow through heat sink by high-pressure pump pressurization cooling water and move in circles through condenser cooling photovoltaic electrification component is lowered the temperature, effectively reduce photovoltaic electrification component surface temperature, reduce power attenuation, it is ensured that power exports.2, arranging three-dimensional coarse strainer prevents the mince main rainwater collection collector that drops of the bulks such as the leaves in water, architect shatter from causing obstruction.3, as a large amount of dust can be accumulated without rainfall then branch collection rain pipe and three-dimensional coarse strainer surface for a long time, the rainwater at initial stage can carry when therefore raining a large amount of impurity, should not use, supersonic liquid level induction apparatus is set and senses when rainwater increases, time control valve will be opened by automatic linkage device automatically, and the initial stage carries the rainwater of impurity and will discharge.4, supersonic liquid level sensor location prevents from ultrasonic sensing that ripples concussion sends false command in cistern less than cistern water inlet.5, condenser uses water condenser or aerial condenser to cooling water refrigeration faster.6, cistern is connected with service water pipeline, and in cistern, the rainwater after precipitation can use as service water, and during for a long time without rainfall, it is also possible to from service water pipeline water filling, service water being poured into cistern is that photovoltaic power station component automatic temp. reducing device carries Cooling Water.
