DETAILED DESCRIPTION
[0016] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.
[0017] The present application embodiment discloses a photovoltaic bracket. Please refer to Figure 1 and Figure 2 The photovoltaic support includes a plurality of pillars 1, diagonal braces 11 fixedly arranged on adjacent pillars 1, cross beams 12 fixedly arranged on the pillars 1, and fixing rods 13 fixedly arranged on the cross beams 12.
[0018] The fixing rod 13 is used to fix the photovoltaic panel. A track groove 14 is provided on the fixing rod 13. A driving mechanism 2 is rollingly abutted in the track groove 14. A ash removal pipe 3 is provided on the driving mechanism 2. The ash removal pipe 3 is spanned across both sides of the photovoltaic panel. A plurality of ash removal holes facing the photovoltaic panel are evenly provided on the ash removal pipe 3. The ash removal pipe 3 is connected to an air compressor.
[0019] Reference Figure 3 The ash removal pipe 3 has a flat structure, and the ash removal hole faces downward for blowing away the dust on the surface of the photovoltaic panel. The two ends of the ash removal pipe 3 are fixedly connected to two extension shafts 31, and a connecting plate 32 is fixedly connected between the adjacent extension shafts 31, and the motor 21 is fixedly set on the connecting plate 32.
[0020] The driving mechanism 2 includes a motor 21 fixedly arranged on the ash removal pipe 3, a main gear 22 arranged on the output shaft of the motor 21, and a slave gear 23 arranged on the ash removal pipe 3, wherein the main gear 22 is meshedly connected with the slave gear 23, a rack 24 is arranged at the bottom of the track groove 14, and the slave gear 23 is meshedly connected with the rack 24. The slave gear 23 is rotatably connected to the extension shaft 31 through a bearing, and the main gear 22 is located between two adjacent slave gears 23 and is meshedly connected with the two adjacent slave gears 23.
[0021] The motor 21 rotates to drive the two slave gears 23 to rotate in the same direction through the main gear 22, and the slave gears 23 can move along the rack 24, thereby driving the sootblowing tube to move horizontally. The diameter of the main gear 22 is smaller than that of the slave gear 23, which is used to reduce the rotation speed of the slave gear 23.
[0022] Furthermore, a dust shielding plate 4 for shielding the track groove 14 is fixedly provided on the fixing rod 13 , and a clearance hole is opened on the side of the dust shielding plate 4 ; a brush 41 for shielding the clearance hole is provided on the dust shielding plate 4 .
[0023] The extension shaft 31 passes through the clearance hole and meshes with the main gear 22 through the slave gear 23. When the extension shaft 31 moves along the clearance hole, the brush 41 is made of flexible material and can be bent, and then restored to verticality after the extension shaft 31 passes. The brush 41 and the dust shield 4 can reduce the external dust from falling on the rack 24, thereby reducing the impact of dust on the drive mechanism 2.
[0024] The embodiment of the present application also discloses a photovoltaic device, which includes a photovoltaic panel and the photovoltaic bracket as described above.
[0025] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
