Embodiment

Below in conjunction with accompanying drawing the utility model is elaborated, yet accompanying drawing is only for reference and the usefulness of explanation, is not to be used for limiting the utility model.

Fig. 2 and 3 is respectively the partial enlarged drawing of a-quadrant among the combination schematic representation of the utility model electricity generating device and Fig. 2, and the utility model provides a kind of device of solar generating, and it mainly comprises support 10, pedestal 20, light-transmitting plate 30 and generator set 40.

Support 10 is combined by a plurality of longitudinal holding poles 11 and a plurality of lateral strut 12 of being connected with each longitudinal holding pole 11 respectively, is used for propping up between pedestal 20 and ground suitable height.

Pedestal 20 is combined by base plate 21 and a plurality of upwardly extending a plurality of coaming plates 22 of base plate 21 peripheries that are connected.Base plate 21 is made by the material with good heat absorptivity, or high heat absorptivity coating directly is applied to (figure does not show) on the upper surface of base plate 21.Base plate 21 is connected lateral strut 12 tops of support 10, and offers a plurality of intake openings 211 at base plate 21.Present embodiment is to be provided with to be provided with the upwards oblique plate 212 of bending in the intake opening 211 on base plate 21, thereby increases the heat absorption surface area of base plate 21.Oblique plate 212 also can be a plurality of independent materials with good heat absorptivity, is bonded with each other with base plate 21 after making, and forms intake opening 211.Oblique plate 212 can be made angular adjustment according to actual user demand with the angle setting of base plate 21, absorbs the solar radiant energy area thereby enlarge effectively, and does good heat exchange with air.
