Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel installation equipment, in particular to a column adjusting device for a photovoltaic power station bracket. Background Technique

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. It mainly consists of three major parts: solar panels, controllers, and inverters, and the main components are composed of electronic components. Solar cells can be encapsulated and protected after being connected in series to form large-area solar cell modules, and then combined with components such as power controllers to form a photovoltaic power generation device.

[0003] In actual use, photovoltaic panels are usually fixedly installed on brackets, and the brackets are fixedly installed at the top of columns. The columns and the brackets are connected by bolts and rotating plates. When installed, the angle of the photovoltaic panels is fixed. If adjustment is needed later, the position or height of the columns needs to be changed, and the corresponding bolts need to be loosened, which is very inconvenient. Since the altitude angle of the sun changes with the revolution of the earth, the angle of the light rays hitting the solar panels changes, thus affecting the power generation of the photovoltaic panels. For household photovoltaic systems, the change in the solar incident angle can be ignored, but for photovoltaic power stations with a large number of photovoltaic panels, the cumulative difference in power generation will be significant. Content of the Utility Model

[0029] Embodiment 1:

[0030] Please refer to Figures 1-4 , and the above technical solutions of the present invention will be described in detail through the following embodiments:

[0031] A column adjusting device for a photovoltaic power station support, comprising:

[0032] A fixed frame 2, the fixed frame 2 is used for installing the photovoltaic panel 1, and the lower part of the fixed frame 2 is connected to the column assembly 4 through a rotating connecting piece 3.

[0033] The photovoltaic panel 1 and the fixing frame 2 are fixedly connected by using a well-known solar panel fastener.

[0034] The fixing frame 2 includes a cross beam 21 and a longitudinal beam 22, and a first chute 23 is provided through the bottom of the longitudinal beam 22.

[0035] The cross beam 21 and the longitudinal beam 22 are fixedly connected by welding.

[0036] The rotating connecting member 3 includes a clamping plate 31 and a sliding plate 32. The clamping plate 31 is fixedly connected to the fixing frame 2, the sliding plate 32 is slidably connected to the fixing frame 2, and the lower parts of the clamping plate 31 and the sliding plate 32 are connected to the column assembly 4 through a rotating assembly. An angle indicating assembly is provided on the rotating assembly for displaying the rotation angle of the rotating assembly.

[0037] The clamping plate 31 and the sliding plate 32 are inserted into the first chute 23.

[0038] The clamping plate 31 is inserted from the end of the longitudinal beam 22 and is fixedly connected to the lower end of the longitudinal beam 22 by bolts to limit the sliding of the longitudinal beam 22. The sliding plate 32 is inserted from the upper end of the longitudinal beam 22 and is slidably connected to the longitudinal beam 22.

[0039] The rotating assembly includes several groups of rotating frames 33 and fixed frames 34. The rotating frames 33 are fixedly installed on the bottom surfaces of the clamping plate 31 and the sliding plate 32. The rotating frames 33 and the fixed frames 34 at the same height are rotatably connected by a connecting rod 37, and locking sleeves 38 are threadedly connected to both ends of the connecting rod 37.

[0040] The locking sleeve 38 is used to limit the sliding of the connecting rod 37 and prevent the connecting rod 37 from falling off.

[0041] An angle scale 35 is provided on the outer lower edge of the rotating frame 33, and an indicating groove 36 is provided in the middle of the outer upper edge of the rotating frame 33. The axis of the indicating groove 36 is perpendicular to the horizontal plane.

[0042] When the rotating frame 33 rotates relative to the fixed frame 34, the angle scale 35 will rotate relative to the indicating groove 36. According to the reading of the angle scale 35 indicated by the indicating groove 36, the rotation angle of the rotating frame 33 can be judged.

[0043] The column assembly 4 includes a fixed column 41 and an adjusting column 42. The fixed column 41 and the adjusting column 42 are connected by a telescopic assembly. The telescopic assembly is used to adjust the distance between the fixed column 41 and the adjusting column 42. A guiding assembly is provided at the bottom of the adjusting column 42. The guiding assembly is used to limit the moving direction of the adjusting column 42.

[0044] Both the fixed column 41 and the adjusting column 42 are made of square steel pipes.

[0045] The fixed column 41 and the adjusting column 42 are fixedly installed below the fixed frame 34. The length of the fixed column 41 is less than that of the adjusting column 42, and the bottom end of the fixed column 41 is buried in the ground.

[0046] The fixing bracket 34 is welded to the tops of the fixed column 41 and the adjusting column 42. The fixed column 41 is located below the clamping plate 31, and the adjusting column 42 is located below the sliding plate 32.

[0047] The guiding assembly includes a slide rail 44, on which a slider 45 is slidably connected. The slider 45 is fixedly installed at the bottom end of the adjusting column 42. A diagonal brace 43 is welded between the slider 45 and the adjusting column 42. The end of the slide rail 44 is fixedly connected to the fixed column 41 by bolts.

[0048] The slide rail 44 is perpendicular to both the fixed column 41 and the adjusting column 42 at the same time. The slide rail 44 cooperating with the slider 45 can limit the moving direction of the adjusting column 42. At the same time, the slide rail 44 can disperse the pressure received by the adjusting column 42. The diagonal brace 43 can provide additional support for the adjusting column 42 to prevent the adjusting column 42 from tipping over.

[0049] The telescopic assembly includes two telescopic rods 46. The heads of the telescopic rods 46 are respectively rotatably connected to the fixed column 41 and the adjusting column 42 by hinges. A adjusting sleeve 47 is threadedly connected between two opposite telescopic rods 46. A chain drive device 48 is provided between the adjusting sleeves 47.

[0050] The thread directions of two opposite telescopic rods 46 are opposite. Rotating the adjusting sleeve 47 can drive the telescopic rods 46 to move along the axis direction of the adjusting sleeve 47, so as to control the distance between the fixed column 41 and the adjusting column 42. The chain drive device 48 can transmit the rotation of one adjusting sleeve 47 to the other adjusting sleeve 47 to ensure that the two adjusting sleeves 47 rotate synchronously.

[0051] Since the heights of the fixed column 41 and the adjusting column 42 remain unchanged, when the distance between them changes, the angle between the connection line of the tops of the fixed column 41 and the adjusting column 42 and the horizontal plane will change. At this time, the sliding plate 32 will move along with the adjusting column 42, and at the same time, rotation will occur between the rotating frame 33 and the fixing bracket 34, so that the angle of the photovoltaic panel 1 will change.

[0052] In this embodiment, when an operator uses this device, first calculate the altitude angle of the sun at noon according to the date.

[0053] Then rotate one of the adjusting sleeves 47, and use the chain drive device 48 to drive the other adjusting sleeve 47 to rotate synchronously.

[0054] Rotating the adjusting sleeve 47 can drive the telescopic rods 46 to move along the axis direction of the adjusting sleeve 47, so as to control the distance between the fixed column 41 and the adjusting column 42.

[0055] When the distance between the fixed column 41 and the adjusting column 42 changes, since the heights of the fixed column 41 and the adjusting column 42 remain unchanged, the angle between the connecting line of the tops of the fixed column 41 and the adjusting column 42 and the horizontal plane will change. At this time, the sliding plate 32 will move along with the adjusting column 42, and at the same time, rotation will occur between the rotating frame 33 and the fixed frame 34, so that the angle of the photovoltaic panel 1 will change.

[0056] When the rotating frame 33 rotates relative to the fixed frame 34, the angle scale 35 will rotate relative to the indicating groove 36. Observe the reading of the angle scale 35 indicated by the indicating groove 36 until the sum of the reading and the solar altitude angle is 90, and then stop rotating the adjusting sleeve 47. At this time, the sunlight at noon is perpendicular to the surface of the photovoltaic panel 1. At this time, the illumination intensity received by the photovoltaic panel 1 is the largest.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
