Abstract
The utility model relates to a snow melting apparatus for solar cell modules. The snow melting apparatus comprises a direct-current power supply and a plurality of solar cell modules. The direct-current power supply is connected with a power bus in a conflux box. The power bus is connected with a plurality of connection cables. A power supply switch and a charging switch, which are connected in parallel, are arranged between the power bus and each connection cable. The connection cables are connected with the plurality of solar cell modules in series. The snow melting apparatus has the beneficial effects that the structure of the solar cell modules is unchanged; the solar cell modules are energized by directly connecting with the external direct-current power supply; the PN junction effect of a solar cell is adopted to heat a cell so as to melt snow on the surface of the cell; and the refit is cheap and convenient.
Description
Technical field
The utility model relates to a kind of device for melting snow of solar module.
Background technology
Solar energy power generating is a kind of important form of renewable energy utilization, and the installed capacity of photovoltaic system is increased sharply.Solar module is in outdoor open-air placement in the solar energy photovoltaic system, and battery component need to be accepted solar radiation could become electric energy with light energy conversion.But in certain areas, owing to there is accumulated snow to cause battery component can not accept radiation at battery component, if only naturally melt accumulated snow by sunlight, energy output can be subject to certain loss.Existing snow removing mode has artificial snow removing, Snow Agent snow removing and electric heating snow removing.Take the patent No. 201220083481 disclosed " Snowmelt Type solar module structure " in the series of patents of the solar module device for melting snow of representative, employing without exception be additionally to increase heater, then heating and melting ice and snow, this is inevitable has by a relatively large margin increased Financial cost, and to solar components that device for melting snow is not installed or can't install, need to make larger change, the artificial workload that increases of above method or needs, perhaps be not suitable for the snow removing of solar module, or needs change the structure of battery component, therefore, said method all has larger limitation.
The utility model content
The purpose of this utility model provides a kind of device for melting snow of solar module, to overcome present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of device for melting snow of solar module, comprise DC power supply and several solar modules, described DC power supply connects the power bus in the header box, described power bus is connected with respectively some stube cables, be provided with power switch in parallel and charge switch between described power bus and the stube cable, described several solar modules of series connection on the described stube cable.
Further, be provided with the outgoing line plug with an import and an outlet between the described solar module.
Further, described solar module is interval with the attachment plug with an import and two outlets.An outlet of described attachment plug links to each other with the negative pole of DC power supply by cable.
The beneficial effects of the utility model are: the solar module structure is not made any change, by external direct current power supply, to the battery component energising, utilize the solar cell PN junction effect, use battery-heating, melt the accumulated snow on surface.The repacking cost is low, reequips easy.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the structural representation of the device for melting snow of the described solar module of the utility model embodiment.
Among the figure:
1, DC power supply; 2, header box; 3, power bus; 4, stube cable; 5, power switch; 6, charge switch; 7, solar module; 8, outgoing line plug; 9, attachment plug.
Embodiment
As shown in Figure 1, the device for melting snow of the described a kind of solar module of the utility model embodiment, comprise DC power supply 1 and several solar modules 7, the power bus 3 that described DC power supply 1 connects in the header box 2, described power bus 3 is connected with respectively some stube cables 4, be provided with power switch in parallel 5 and charge switch 6 between described power bus 3 and the stube cable 4, described several solar modules 7 of series connection on the described stube cable 4.Be provided with the outgoing line plug 8 with an import and an outlet between the described solar module 7.Described solar module 7 is interval with the attachment plug 9 with an import and two outlets.An outlet of described attachment plug 9 links to each other with the negative pole of DC power supply 1 by stube cable 4.
The device for melting snow of the solar module that the utility model provides, DC power supply 1 are the electric main behind over commutation, or accumulated snow melted later solar module 7, are used for providing power supply to the solar module 7 that needs snow melt.Header box 2 will organize more the solar module 7 that is serially connected both positive and negative polarity each pool together through bus-bar, just very+, negative pole is-.Solar module 7 can be that many groups are confluxed, also can one group.Power switch 5 and charge switch 6 can connect or disconnect power supply and determine whether to solar module 7 power supplies with snow melt, when power switch 5 is connected, solar module 7 normal power generation work, when charge switch 6 is connected, with power connection, give solar module 7 power supplies, snow melt.During solar module 7 normal operation solar energy is converted to electric energy, when snow melting, DC power supply 1 gives solar module 7 energisings, and solar module 7 produces heat, melts the accumulated snow on surface.Stube cable 4 connects solar module 7 and header box 2, DC power supply 1 etc.Outgoing line plug 8 between the solar module 7 interconnects or is connected with cable.Be one-in-and-one-out, attachment plug 9 can one be advanced scene 2.After solar module 7 surface is snowy, by the automatic or artificial method of control system, make external direct current power supply 1 or removed the snow after solar module 7 square formations as power supply, give the power supply of solar module 7 square formations.Solar module 7 serial numbers are different, and then voltage is different, and the power of required snow melt is different, can be inserted in different positions by attachment plug 9.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection range of the present utility model.
