The application process of the angle-adjustable photovoltaic support is as follows: first, install the support base 1 on the foundation, and then install the installation bracket 3 and the support rod 2. After the installation is completed, adjust the length of the support rod 2 and slide the support rod at the same time 2. Since one end of the installation bracket 3 is hinged to one end of the support base 1; the other end of the installation bracket 3 is hinged to the support rod 2; thus the angle between the installation bracket 4 and the horizontal plane meets the installation requirements. At this time, the support rod 2 is locked in the chute 11 by the locking device 5 . Then the supporting plate 6 is installed on the mounting support 4 on the mounting bracket 3 , and finally the solar cell panel is installed in the groove 7 of the supporting plate 6 . After the installation is completed, recheck the angle between the solar panel and the horizontal plane. If it is unqualified, loosen the support rod 2 through the locking device 5, and then slide the support rod 2; until the solar panel is at the required angle, through the locking The device 5 locks the support rod 2; thereby realizing the adjustment of the angle between the solar panel and the horizontal plane. Because the mounting bracket 3 is hinged with one end of the support base 1, and the support rod 2 provided between the support base 1 and the mounting bracket 3 is a telescopic rod with adjustable length; at the same time, one end of the support rod is slidably installed on the chute of the support base Inside. Therefore, when the angle of the solar panel installed on the mounting bracket 3 needs to be adjusted, it is only necessary to adjust the height of the support bar, and when the support bar 2 slides to the corresponding position in the chute 11, it can be locked by the locking device 5 . The angle adjustment of the solar panel can be realized, so that the installation is convenient, and at the same time, it is applicable to different installation sites. It is possible to avoid a situation in which the installation of the photovoltaic bracket corresponds to the installation of the photovoltaic module one by one.

In order to facilitate linear adjustment of the sliding of the support rod 2 relative to the support base 1, the locking device 5 includes a locking bolt 51; the side of the support base 1 is provided with a second sliding groove 12 penetrating to the opposite side, And the second chute 12 is in communication with the chute 11; one end of the locking bolt 51 passes through the second chute 12 and the support rod 2 in the chute 11 from the side of the support seat 1, and on the side of the support seat 1 The other side cooperates with the nut. When the support rod 2 needs to be locked, it is only necessary to twist the nut, and the support rod 2 is locked on the support seat 1 through the nut and the locking bolt 51 .

The main function of the support rod 2 is to support the installation bracket 3 . In order to save cost, it is easy to install, and at the same time it is convenient to adjust the length; The third chute 211 in the length direction, the outer rod 22 is provided with a fourth chute 221 along the length direction; the outer rod 22 is sleeved on the inner rod 21; the third chute 211 and the first The four chutes 221 are aligned, and one end of the second locking bolt 23 passes through the third chute 211 and the fourth chute 221 from one side of the outer rod 22 , and connects with the second locking nut on the other side of the outer rod 22 . 24 fits.

In order to facilitate maintenance; it is convenient to replace when one end of the support rod 2 and the support seat 1 slides relatively is worn. Further, the outer rod 22 of the support rod 2 is set on the inner rod 21, and the other end is provided with a sliding seat 25; one end of the sliding seat 25 cooperates with the chute 11, and the other end is detachably connected with the outer rod 22, so A through hole 251 is provided at the end of the sliding seat 25 that cooperates with the sliding groove 11 , and the locking bolt 51 passes through the through hole 251 . By setting the sliding seat 25, the sliding seat 25 is in sliding contact with the supporting seat 1, so when the sliding seat 25 wears out, only the sliding seat 25 needs to be replaced instead of the whole supporting rod 2, thereby reducing the maintenance cost.

In order to reduce the weight of the support rod 2, further, the inner rod 21 of the support rod 2 is provided with a central through hole. In order to save cost and facilitate manufacture, preferably, the inner rod 21 and the outer rod 22 of the support rod 2 are made of aluminum alloy.
