[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] An embodiment of the utility model provides a glass fiber reinforced resin type adjustable photovoltaic bracket, including a support column 10, a base plate 20, a connecting piece 30, a main beam 40, a photovoltaic mounting frame 50 and a driving unit 60. The support column 10 is made of glass fiber reinforced resin, the base plate 20 is used to be fixedly connected to the foundation pile, and the lower end of the support column 10 is fixed to the base plate 20; the connecting piece 30 is fixed to the upper end of the support column 10; the main beam 40 is horizontally mounted on the connecting piece 30 and is rotatably connected to the connecting piece 30; the photovoltaic mounting frame 50 is fixed to the main beam 40 for photovoltaic panel installation; one end of the driving unit 60 is connected to the support column 10, and the other end of the driving unit 60 is connected to the main beam 40 for driving the main beam 40 to rotate.

[0034] Specifically, the photovoltaic bracket is provided with a support column 10, a base plate 20, a connecting piece 30, a main beam 40 and a photovoltaic mounting frame 50. The base plate 20 is fixedly connected to the foundation pile, and the lower end of the support column 10 is fixed to the base plate 20, so that the photovoltaic bracket can be fixed on the foundation pile. Since the support column 10 is made of glass fiber reinforced resin, the acid and alkali resistance of the support column 10 can be effectively improved. The main beam 40 is rotatably connected to the connecting piece 30, and the photovoltaic mounting frame 50 is fixed to the main beam 40, so that when the main beam 40 rotates, it can drive the photovoltaic mounting frame 50 to rotate synchronously. The photovoltaic mounting frame 50 can be used for photovoltaic panel installation. Since the photovoltaic bracket is also provided with a driving unit 60, the driving unit 60 is connected to the main beam 40. The driving unit 60 can realize autonomous adjustment of the angle of the photovoltaic panel on the photovoltaic mounting frame 50 by driving the main beam 40, so that the photovoltaic panel can better match the light and improve the power generation efficiency of the photovoltaic panel.

[0035] It can be understood that the number of support columns 10 can be adaptively set according to the number of supported photovoltaic panels.

[0036] In this embodiment, the bottom plate 20 is a steel plate, and the bottom plate 20 is fixed to the foundation piles by bolts.

[0037] In this embodiment, in order to ensure the stability of the support column 10 and the bottom plate 20 , a reinforcing rib 11 connected to the bottom plate 20 is further provided at the lower end of the support column 10 .

[0038] In one embodiment, the upper end of the support column 10 is provided with a plurality of threaded connection holes 12 spaced apart in the height direction, and the connector 30 is fixedly connected to some of the threaded connection holes 12 by bolts. Specifically, the connector 30 can be detachably connected to the support column 10 by fastening with bolts, and the provision of the plurality of threaded connection holes 12 can realize the adjustment of the height direction of the connector 30, so that different installation heights of the connector 30 can be matched as needed.

[0039] In one embodiment, the main beam 40 is made of glass fiber reinforced resin. Specifically, the main beam 40 is made of glass fiber reinforced resin material, which can effectively enhance the acid and alkali resistance of the main beam 40, thereby preventing the main beam 40 from corroding in a high acid and alkali sand environment and improving the service life of the photovoltaic bracket.

[0040] In this embodiment, since the production cost of the main beam 40 and the support column 10 is relatively high, by setting the main beam 40 and the support column 10 to acid and alkali resistant glass fiber reinforced resin, corrosion of the main beam 40 and the support column 10 can be avoided, thereby avoiding subsequent replacement that leads to an increase in the use cost of the photovoltaic bracket.

[0041] In one embodiment, a supply and rotation sleeve 31 is provided at the upper end of the connecting member 30, and the main beam 40 is penetrated by the supply and rotation sleeve 31 and is rotatably connected with the supply and rotation sleeve 31. Specifically, the supply and rotation sleeve 31 can realize the stable rotation of the main beam 40 relative to the connecting member 30, and when the supply and rotation sleeve 31 is worn, only the connecting member 30 needs to be replaced.

[0042] In one embodiment, a rotating sleeve 41 is sleeved on the surface of the main beam 40, a supply rotation groove is formed on the surface of the rotating sleeve 41, and the supply rotation sleeve 31 is embedded in the supply rotation groove, and the main beam 40 is rotatably connected to the supply rotation sleeve 31 through the rotating sleeve 41. Specifically, since the main beam 40 is a square structure, it is difficult to directly rotate inside the supply rotation sleeve 31. By sleeved the rotating sleeve 41 on the main beam 40, the axial movement of the main beam 40 can be restricted while the rotation of the main beam 40 is realized, thereby ensuring the stability of the main beam 40.

[0043] In one embodiment, the photovoltaic mounting frame 50 includes a plurality of brackets 51, each bracket 51 being arranged on the main beam 40 at intervals along the axial direction of the main beam 40. Specifically, the photovoltaic panel can be supported by each bracket 51 to achieve stability on the photovoltaic bracket.

[0044] In one embodiment, the bracket 51 includes a cross bar 511 and a connecting frame 512 . The cross bar 511 is vertically fixed to the upper side of the main beam 40 , and the connecting frame 512 is fixed to the lower side of the main beam 40 . Both ends of the connecting frame 512 are fixed to the cross bar 511 .

[0045] It can be understood that the driving unit 60 can be any driving device such as an electric motor that can drive the main beam 40 to rotate.

[0046] In one embodiment, the driving unit 60 includes a hydraulic cylinder 61 and a connecting arm 62, wherein the connecting arm 62 is fixed to the main beam 40, one end of the hydraulic cylinder 61 is hinged to the support column 10, and the other end of the hydraulic cylinder 61 is hinged to the connecting arm 62. Specifically, the hydraulic cylinder can drive the main beam 40 to rotate by driving the connecting arm 62, thereby adjusting the angle of the photovoltaic panel.

[0047] In one embodiment, the main beam 40 is a square structure, and one end of the connecting arm 62 close to the main beam 40 is sleeved on the main beam 40. Specifically, the square structure of the main beam 40 can facilitate the fixation of the photovoltaic mounting frame 50, improve the stability between the photovoltaic mounting frame 50 and the main beam 40, and strengthen the structure of the main beam 40 to prevent the main beam 40 from deformation.

[0048] In one embodiment, the driving unit 60 further includes a connecting shaft 63, a plurality of hydraulic cylinders 61 are provided, and each hydraulic cylinder 61 is arranged at intervals, and the connecting shaft 63 is connected to each hydraulic cylinder 61. Specifically, the connecting shaft 63 can ensure the synchronous driving of each hydraulic cylinder 61, and the main beam 40 can achieve stable adjustment of the angle of the photovoltaic panel through the synchronous driving of each hydraulic cylinder 61.

[0049] In one embodiment, the connecting shaft 63 includes a rod body 631 and universal joints 632 installed at both ends of the rod body 631, and the universal joints 632 at both ends are respectively fixed to two adjacent hydraulic cylinders 61. Specifically, by setting the rod body 631 connecting shaft 63 as the rod body 631 and the universal joint 632, the position of each hydraulic cylinder 61 can have a certain fault tolerance performance, and while realizing the synchronous driving of the photovoltaic mounting frame 50, it can also provide convenience for the installation of each hydraulic cylinder 61.
