Detailed description of the invention

This utility model is described in further detail by 1 to Fig. 3 below in conjunction with the accompanying drawings.

The roof that Fig. 1 to Fig. 3 show schematically show according to a kind of embodiment of the present utility model can Adjust photovoltaic bracket.As shown in Figure 1 to Figure 3, this roof adjustable photovoltaic support, including two groups of support bodys and For connecting the bracing piece 7 of two groups of support bodys, often group support body include push rod 2, pressure pin the 6, first ground 11, Second ground 12 and be fixedly connected on the positioning element 3 on the first ground 11；The top of push rod 2 and torr The top of bar 6 is rotationally connected, and specifically can be by bearing pin inlet wire and connects, certainly can also is that other Connector realizes being rotationally connected.Bracing piece 7 two ends are passed through with the push rod 2 in two groups of support bodys respectively Bolt is fixedly connected；Pressure pin 6 bottom is movably connected on the second ground 12, and push rod 2 bottom sets Having Plug Division 21, push rod 2 to be connected with positioning element 3 by Plug Division 21, photovoltaic panel is positioned at pressure pin On 6.

Pressure pin 6 bottom is fixedly connected on the second ground 12, in use can be by adjusting pressure pin The position of 6, to regulate the angle of photovoltaic panel and horizontal plane；Push rod 2 top rotates with pressure pin 6 top Connect, make photovoltaic array mounted angle can adapt to different regions and season changes flexibly, make full use of Solar energy, to obtain maximum solar radiation quantity, effectively reduces fixed angle photovoltaic bracket in photovoltaic system The summer generating electricity in winter amount significantly gap brought.

As shown in Figure 1 to Figure 2, in order to the regulation of photovoltaic array setting angle, location division can be carried out Part 3 is provided with hole 4, at least two location, and push rod 2 bottom is matched with hole 4, location by Plug Division 21 Close.By converting the hole, location 4 of diverse location, the regulation of photovoltaic array setting angle can be carried out.

As shown in Figure 1 to Figure 2, Plug Division 21 is in inverted T shape, and the two ends bottom Plug Division 21 are with fixed Hole 4, position coordinates clamping.It provides the benefit that, after hole 4, location is inserted in Plug Division 21, and Plug Division 21 The two ends of bottom launch to fix push rod 2, thus fix photovoltaic array mounted angle, to obtain Maximum solar radiation quantity.

In order to regulate the angle of photovoltaic panel and horizontal plane more flexibly, push up at the second ground 12 Portion is also fixed with connector, and pressure pin 6 bottom can match with connector and be connected.The most permissible Connected by hinges, certainly can also is that other connector realizes being flexibly connected.Pressure pin 6 Bottom is movably connected on the second ground 12, in use can be by the position of pressure pin 6 is adjusted flexibly Put, to regulate the angle of photovoltaic panel and horizontal plane.According to principle at sunshine, photovoltaic array enters with the sun When firing angle is in 90 °, the solar radiation quantity of maximum can be obtained.Solar energy to be made full use of, no Need with different seasonal move with the photovoltaic array mounted angle in area.Especially the Spring Equinox, the Summer Solstice, The Autumnal Equinox, Winter Solstice are the turning points that solar incident angle changes.

Below with the photovoltaic array installed on the Northern Hemisphere, four inclination angles of annual regulation are that example is analyzed. During the Spring Equinox, sunlight vertical irradiation is on equatorial line, and declination angle is 0 °, for obtaining maximum sun spoke The amount of penetrating, the installation optimum angle of incidence of photovoltaic array is local latitude angle；Positioning element 3 is provided with at least two Hole, individual location 4, is matched with hole 4, location by Plug Division 21 in push rod 2 bottom.Conversion diverse location Hole, location 4, regulation photovoltaic array setting angle be local latitude angle.

Sunlight vertical irradiation in the Spring Equinox to Summer Solstice position is also moved to the tropic of cancer by equator, and sun equatorial angle is 23 ° 27 ', the hole, location 4 of conversion diverse location, adjust angle between pressure pin 6 and push rod 2, make light It is that angle of latitude deducts 23 ° 27 ' that photovoltaic array installs optimum angle of incidence；

By the Summer Solstice again to the Autumnal Equinox, sunlight vertical irradiation position is moved to equatorial line, the Autumnal Equinox by the tropic of cancer again 0 ° it is all mutually with the declination angle in the Spring Equinox, in like manner, the hole, location 4 of conversion diverse location, make photovoltaic The installation optimum angle of incidence of array is local latitude angle；

By the Autumnal Equinox again to Winter Solstice, sunlight vertical irradiation position is moved to south by equatorial line and reaches the same goal line, and the sun is red Latitude angle is-23 ° 27 ', in like manner, the hole, location 4 of conversion diverse location, make photovoltaic array install and most preferably incline Angle is that angle of latitude adds 23 ° 27 ', the change of sunlight vertical irradiation position can respectively the Spring Equinox, the Summer Solstice, The inclination angle of photovoltaic array was regulated before the Autumnal Equinox, Winter Solstice.If the declination angle in the Northern Hemisphere is positive number, south half The declination angle of ball is negative.Annual sunlight moves in the tropic of cancer to the tropic of Capricorn, photovoltaic battle array The mounted angle of row takes local latitude and deducts declination angle.

Above-described is only embodiments more of the present utility model.Ordinary skill for this area For personnel, on the premise of creating design without departing from this utility model, it is also possible to make some deformation And improvement, these broadly fall into protection domain of the present utility model.
