[0025] Please refer to Figure 1-6, a pull-out type photovoltaic bracket provided by an embodiment of the present utility model includes a fixed bracket 1 on which a photovoltaic panel can be installed. It further includes a first sliding bracket 2, a second sliding bracket 3, and a wire guiding mechanism. The first sliding bracket 2 is slidably connected to the fixed bracket 1, and a photovoltaic panel can be installed on the first sliding bracket 2; the second sliding bracket 3 is slidably connected to the fixed bracket 1, and the sliding directions of the first sliding bracket 2 and the second sliding bracket 3 relative to the fixed bracket 1 are opposite, and a photovoltaic panel can be installed on the second sliding bracket 3; the wire guiding mechanism is used to guide the running directions of the positive and negative wire harnesses of the photovoltaic panels installed on the fixed bracket 1, the first sliding bracket 2, and the second sliding bracket 3. Limit brackets 8 for limiting and fixing the photovoltaic panels are provided on both the first sliding bracket 2 and the second sliding bracket 3.

[0026] The wire guiding mechanism includes a first wire collecting groove 11, a wire hole group 4, a second wire collecting groove 12, a first through-hole group 5, and a second through-hole group 6. The first wire collecting groove 11 is provided on the fixed bracket 1 and is used to guide the running directions of the positive and negative wire harnesses of the photovoltaic panel on the fixed bracket 1; the wire hole group 4 is provided on the fixed bracket 1 and is used to change the running directions of the positive and negative wire harnesses of the photovoltaic panel on the fixed bracket 1. Specifically, the wire hole group 4 includes a first wire hole 41, a second wire hole 42, a third wire hole 43, and a fourth wire hole 44. The first wire hole 41, the second wire hole 42, the third wire hole 43, and the fourth wire hole 44 are all opened on the fixed bracket 1, and while changing the running directions of the positive and negative wire harnesses of the photovoltaic panel on the fixed bracket 1, the wire hole group 4 does not affect the sliding of the first sliding bracket 2 and the second sliding bracket 3; the second wire collecting groove 12 is provided on the fixed bracket 1 and is used to guide the running directions of the positive and negative wire harnesses on the photovoltaic panel on the fixed bracket 1; the first through-hole group 5 is used to guide the running directions of the positive and negative wire harnesses of the photovoltaic panel on the first sliding bracket 2; the second through-hole group 6 is used to guide the running directions of the positive and negative wire harnesses of the photovoltaic panel on the second sliding bracket 3. Specifically, the first through-hole group 5 includes a first wire collecting hole 51 and a first wire guiding hole 52. The first wire collecting hole 51 is opened on the first sliding bracket 2, and the first wire guiding hole 52 is opened on the fixed bracket 1. The second through-hole group 6 includes a second wire collecting hole 61 and a second wire guiding hole 62. The second wire collecting hole 61 is opened on the second sliding bracket 3, and the second wire guiding hole 62 is opened on the fixed bracket 1.

[0027] Working principle: Three photovoltaic panels, namely the first photovoltaic panel, the second photovoltaic panel, and the third photovoltaic panel (each photovoltaic panel has the same structure and is a Figure 6 photovoltaic panel 9 with positive and negative wire harnesses provided), can be installed on the bracket. The positive and negative wire harnesses of the first photovoltaic panel are accumulated together through the first wire collecting groove 11 (such as Figure 3The routing of the positive and negative wire harnesses of the provided first photovoltaic panel), and then guide the positive and negative wire harnesses of the first photovoltaic panel according to the guiding direction of the first wire trough 11. During this process, the first photovoltaic panel will sequentially pass through the first wire hole 41, the second wire hole 42, the third wire hole 43, and the third wire hole 43. The positive and negative wire harnesses of the first photovoltaic panel pass through the first wire hole 41 and enter the first wire trough 11. This is to avoid affecting the installation of the first photovoltaic panel. From the first wire hole 41 to the second wire hole 42, it is to prevent the positive and negative wire harnesses of the first photovoltaic panel from directly passing through the fixing frame 1 and thus interfering with the sliding of the first sliding frame 2 and the second sliding frame 3. From the second wire hole 42 to the third wire hole 43, the routing of the first photovoltaic panel is changed, so that the positive and negative wire harnesses of the first photovoltaic panel enter the second wire trough 12 from the first wire trough 11. The second wire trough 12 is on the back of the fixing frame 1, which can hide the positive and negative wire harnesses of the first photovoltaic panel. Then, there is a position after the wire trough where the positive and negative wire harnesses of the first photovoltaic panel are separated and then the positive and negative wire harnesses are guided in opposite directions (such as Figure 4 ), then lead out the positive and negative wire harnesses of the second photovoltaic panel through the first lead hole 52 from the first sliding frame 2, and then lead the positive and negative wire harnesses of the second photovoltaic panel to the first lead hole 52, so that the positive and negative wire harnesses of the second photovoltaic panel can enter the second wire trough 12 from the first lead hole 52. Guide the positive and negative wire harnesses of the third photovoltaic panel in the same way, so that the positive and negative wire harnesses of the third photovoltaic panel also enter the second wire trough 12. In the second wire trough 12, the positive wire harness of the first photovoltaic panel is connected to the negative wire harness of the second photovoltaic panel, and the negative wire harness of the first photovoltaic panel is connected to the positive wire harness of the third photovoltaic panel. Then, guide the positive wire harness of the second photovoltaic panel and the negative wire harness of the third photovoltaic panel together in the second wire trough 12, so that the positive wire harness of the second photovoltaic panel and the negative wire harness of the third photovoltaic panel are connected to the controller (this is the prior art and is not shown in the figure, so there will be no further elaboration here), realizing the circuit closure of the first photovoltaic panel, the second photovoltaic panel, the third photovoltaic panel, and the controller. Finally, the installation of each photovoltaic panel can be carried out.

[0028] Compared with the prior art, a pull-out photovoltaic bracket provided by the present utility model slides the first sliding and the second sliding frame 3 out of the fixing frame 1, and then installs photovoltaic panels on the fixing frame 1, the first sliding frame 2, and the second sliding frame 3 respectively. The lead wire mechanism is used to guide, hide, and restrain the positive and negative wire harnesses of each photovoltaic panel, so that the positive and negative wire harnesses on each photovoltaic panel can be arranged orderly on the bracket, avoiding the risk of the wire harness swinging randomly, sagging, or contacting other objects, and thus reducing the risk of fire or electric shock caused by wire harness wear, short circuit, etc.

[0029] Among them, a wire shielding shell 13 is also provided on the fixing frame 1. If the positive and negative wire harnesses on the fixing frame 1 are too long, a part can be stored between the third wire hole 43 and the fourth wire hole 44. On the one hand, the wire shielding shell 13 can play a role in receiving and supporting, and on the other hand, the wire shielding shell 13 can shield this section of the wire harness.

[0030] Among them, partitions 7 are provided on both the first wire collecting groove 11 and the second wire collecting groove 12. A plurality of positioning clips 71 are provided on both sides of the first wire collecting groove 11 and the second wire collecting groove 12 located on both sides of the partition 7. The partition 7 separates the positive and negative wire harnesses on the fixing frame 1 to prevent the positive and negative wire harnesses from being wound together. In addition, the plurality of positioning clips 71 can play a role in fixing the wire harnesses.

[0031] Among them, a plurality of drain holes 14 are formed at the bottom of the fixing frame 1. The plurality of drain holes 14 serve to drain the rainwater falling on the fixing frame 1. In addition, the setting of the plurality of drain holes 14 can also reduce the mass of the bracket.

[0032] Only some exemplary embodiments of the present invention have been described above by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
