Embodiment
Refer to the preferred embodiment of solar energy equipment of the present invention shown in the drawings, these embodiment, only for explanation, are not subject to the restriction of this structure in patented claim.
Fig. 1 is the fixing support bar of described tie point employing draw-in groove, tongue and mortise mode and the connector schematic diagram being mated; Fig. 2 is that described tie point adopts the fixing support bar of pin-and-hole pin mode and the connector schematic diagram being mated.During actual use, can take either type.
Described photovoltaic panel 1 is arranged on above support 2, and one end of described support bar 3 is connected with described photovoltaic panel 1, and the different angles that the other end need to be adjusted to according to described photovoltaic panel 1 connect from different tie points on corresponding connector 4.
Described support bar 3 connects from described different tie points, the angle between described photovoltaic panel 1 and surface level is made adjustment, annual different times by described angle adjusted at that time, local most suitable inclination angle, make year optimum angle of incidence deduct 23.5 degree with year an optimum angle of incidence add between 23.5 degree adjustable.Described support bar is fixed with the form of draw-in groove trip or the form of pin-and-hole pin that being connected of described tie point adopts Fig. 1 or Fig. 2 to show, and described photovoltaic panel 1 is formed and supported.
The quantity of the draw-in groove shown in Fig. 1 and Fig. 2 or pin-and-hole is at least 2 covers.
Connector 4 shown in Fig. 1 and Fig. 2 can be fixed on above support 2 after making, and also its draw-in groove or pin-and-hole can be set directly on above support 2, and described connector 4 and above support 2 are combined together.
Trip shown in Fig. 1 and Fig. 2 can be threaded nut, or not threaded nut, and shown pin-and-hole pin can be with the screw thread matching or not threaded.
The transverse section of the support bar shown in Fig. 1 and Fig. 2 can be circle, square or other geometrical forms.
Fig. 3 to Fig. 5 is several examples of solar energy equipment embodiment of the present invention.In these examples, stilt can be fixed, make the direction of photovoltaic panel 1 positive installation be due south (being that position angle is 180 degree) on the Northern Hemisphere, in the Southern Hemisphere, be positive north (being that position angle is zero degree), also can be horizontal azimuth adjustable (being that horizontal direction is rotatable).What the present invention discussed is only the adjustment to pitch angle, photovoltaic panel north and south.
In the embodiment of Fig. 3 to Fig. 5, stilt is selected, or the installation site of support bar 3 is different, but its principle is identical with annexation, under the situation of satisfying the demand, can select various different modes.
Shown in Fig. 3 to Fig. 5, Fig. 3 and the difference of Fig. 4, Fig. 5 are supporting way different of stilt 2, in Fig. 3, stilt 2 is also not shown, stilt 2 can be directly ground or other horizontally disposed holders, supporting way is upper support, and the tie point of support bar 3 and photovoltaic panel 1 is higher than the tie point of photovoltaic panel 1 and stilt 2; And in Fig. 4 to Fig. 5, stilt 2 is the vertical plane of the objects such as column or wall, supporting way is lower support, and the tie point of support bar 3 and photovoltaic panel 1 is lower than the tie point of photovoltaic panel 1 and stilt 2.
In the various embodiments described above, photovoltaic panel 1 is connected with stilt 2, and is coupling with being connected to of support bar 3, or uses flexible material to connect, and with in the situation that guaranteeing strength of joint, can correspondingly adjust connection angle.
Mode as an alternative, above support 2 is fixed or horizontal azimuth is adjustable.
When the angle of adjusting between described photovoltaic panel 1 and surface level, relevant with the year optimum angle of incidence of particular location.The year optimum angle of incidence of various places generally adds by the modified value of calculating and empirical data draws and draws with local latitude, has been well known data.Take Beijing as example, and a year optimum angle of incidence is 36 degree, and while using product of the present invention in Beijing, the angle between photovoltaic panel 1 and surface level can subtract 23.5 degree and 36 degree at 36 degree and add between 23.5 degree and change, and between 12.5 degree and 59.5 degree, changes.
At latitude compared with low country, year optimum angle of incidence subtracts 23.5 degree, it is negative may making numerical value, now adopt lower support, the tie point of adjustable support bar 3, make photovoltaic panel 1 be subject to turn in a side direction of its support the appropriate location with stilt tie point higher than photovoltaic panel 1, maybe an other side that supports pole 3 and be arranged on photovoltaic panel 1 is solved.
Take and adjust every year 4 times as example, described connector need be established 3 tie points, as in Beijing area, operate according to the following steps, every year by that analogy:
(1) February 20: photovoltaic panel 1 and the angle of surface level are adjusted to year optimum angle of incidence 36 degree (optimum angle of incidence of Beijing day in the Spring Equinox and day in the Autumnal Equinox), support bar 3 is connected with middle tie point, is fixed.
(2) April 20: photovoltaic panel 1 and the angle of surface level are adjusted to 12.5 degree (optimum angle of incidence of Beijing summer solstice, year optimum angle of incidence 36 degree subtract tropic latitude 23.5 degree).As supporting way be as described in upper support, by support bar 3 with apart from photovoltaic panel 1 tie point farthest, be connected, fixing; As supporting way be as described in lower support, support bar 3 is connected with the tie point nearest apart from photovoltaic panel, fixing.
(3) August 24: repeat the adjustment of (1);
(4) October 23: photovoltaic panel and horizontal plane angle are adjusted to inclination maximum 59.5 degree (Beijing
The optimum angle of incidence of winter solstice).As supporting way be as described in upper support, by support bar 3 be connected with the tie point nearest apart from photovoltaic panel, fixing; As supporting way be as described in lower support, by support bar 3 with apart from photovoltaic panel tie point farthest, be connected, fixing.
Above optimum angle of incidence and adjustment date are according to known data and method meters such as solar declination Changing Patterns
Calculate, the length of support bar, and the position of each tie point is according to required adjustment angle calculation and setting, at this, all repeats no more.
Prove through calculation and test, as by as described in use 3 cover tie points are annual adjusts 4 times, average of the whole year can make the luminous flux of unit area sunlight in photovoltaic panel 1 reach solar declination is carried out to 99.5% of the full-time tracking in north and south.As annual adjustment 12 times (using 7 cover tie points) can reach 99.8%.
Adopt the solution of the present invention, the cost of increase is the expense for replacing fixed bracing or strutting arrangement with described adjustable supporting device only.And described adjustable supporting device is just used common material, it is little that its cost and fixed bracing or strutting arrangement are compared difference.And the human cost of using while regulating photovoltaic panel angle is negligible.Reason is, photovoltaic panel needs often to make an inspection tour and maintaining, to prevent sleet, birds droppings or other foreign substance pollutions (preventing that hot spot effect from causing mortal wound), and the one group of simple motion increasing while using manpower that this patent increases just to make an inspection tour and safeguard in the specific date.And the present invention program is simple and reliable for structure, almost without any maintaining.
The above; be only the specific embodiment of the present invention and example, but protection scope of the present invention is not limited to this, any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
