Description

[0002] At present, photovoltaic equipment has entered thousands of households, thanks to the continuous progress of photovoltaic technology and the continuous improvement of the efficiency of photovoltaic modules. At the same time, the increasing maturity of technologies such as energy storage and microgrids has provided strong support for the further development of distributed photovoltaics. With technological progress and large-scale production, the cost of photovoltaic systems has continued to decrease, and grid parity has gradually been achieved, and the dependence on subsidies has gradually decreased. This makes photovoltaic systems more competitive in the market and attracts more users to install them.

[0003] As for the installation and use of photovoltaic panels in some small households, due to the limitation of installation location, small demand for use or limited installation cost, it is impossible to install photovoltaic panels in batches. They can only be installed and used on a small scale in the form of single pieces. However, the single-piece photovoltaic panels will have the highest power generation efficiency only when they just cover the entire surface of the photovoltaic panel, while other inclined angles or the back will cause the photovoltaic panel to fail to generate electricity well. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a bracket which is convenient for adjusting the light-chasing angle of a photovoltaic panel. The photovoltaic panel can be axially rotated in situ through an axial rotating component, and the angle adjustment component can adjust the inclination angle of the photovoltaic panel. Therefore, during the linkage process, the photovoltaic panel can be kept facing the sun to achieve the most efficient power generation.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A bracket for adjusting the light-chasing angle of a photovoltaic panel comprises a support frame, a panel fixing frame, an axial rotating component, an angle adjusting component and a photovoltaic panel. A mounting plate is provided at the bottom of the support frame, and a plurality of mounting holes are provided on the mounting plate.

[0007] The axial rotating component includes a rotating seat and a rotating motor. The rotating seat can be rotatably connected to the support frame. The rotating motor is arranged on the support frame and drives the rotating seat to rotate. An internal gear is provided at the bottom of the rotating seat. The rotating seat is detachably connected to the support frame through a bearing at the center thereof. The rotating motor is arranged on a bracket at the upper end of the support frame. The first gear on the output end of the rotating motor is meshed with the internal gear.

[0008] The angle adjustment component includes a rack, a pushing motor and a transmission box, one end of the rack is rotatably connected to the upper end of the fixed plate frame, the other end of the rack penetrates into the transmission box, the pushing motor is arranged outside the transmission box, the output end of the pushing motor passes through the transmission box and meshes with the rack, the transmission box includes a base box and a box cover, the base box is provided with an active cavity for the rack to pass through, the second gear on the output end of the pushing motor meshes with the rack in the active cavity, the box cover is detachably connected to the base box and covers the active cavity, the transmission box is rotatably connected to one end of the rotating seat, the rotating seat is provided with a rotating seat, the fixed plate frame is provided with a rotating column, the rotating column is cooperatively connected to the rotating seat, the other end of the rotating seat is rotatably connected to the lower end of the fixed plate frame, and the photovoltaic panel is detachably connected to the fixed plate frame.

[0009] The bracket adopts this structure to facilitate adjustment of the photovoltaic panel chasing angle. The bottom of the support frame is installed through the mounting holes on the mounting plate, and the anchor screws pre-buried in the mounting position are installed, and the nuts are screwed in to lock them, so that the support frame is installed and fixed. An axial rotating component is installed at the upper end of the support frame, and the upper end of the support frame is embedded in the bearing at the center of the rotating seat. Therefore, the rotating seat can rotate axially with the support frame as the rotation center. In order to achieve control of the rotation angle, an internal gear is provided at the bottom of the rotating seat, and the center of the internal gear coincides with the center of the bearing. A rotating motor is then installed on the bracket on the support frame. The output end of the rotating motor faces upward and is installed with a first gear, which meshes with the internal gear. Therefore, in the process of starting the rotating motor for forward or reverse rotation, the rotating seat can rotate axially due to the meshing of the first gear and the internal gear, so the photovoltaic panel on the fixed plate frame installed on the rotating seat can rotate axially.

[0010] In order to adjust the angle of the photovoltaic panel, a transmission box is rotatably connected to one end of the rotating seat. The transmission box consists of a base box and a box cover. A rack is inserted into an active cavity that runs through the base box from top to bottom. The second gear on the output end of the push motor outside the base box meshes with the rack in the active cavity. The setting of the active cavity makes it convenient to add lubricating oil here so that the rack can move more smoothly. After refueling, the box cover is closed on the base box and screwed to lock it, thereby closing the active cavity. Therefore, when the push motor is started, the second gear can drive the rack to move up and down, and the upper end of the rack can rotate The rack is rotatably connected to the upper end of the plate fixing frame, so the plate fixing frame can move up and down with the rack during the up and down movement of the rack. Since the lower end of the plate fixing frame is matched with the swivel seat on the swivel seat through the swivel column thereon, when observed from the side, the rack, the plate fixing frame and the swivel seat form a triangular structure with the swivel seat as the base. Therefore, when the rack moves downward, the plate fixing frame will use the swivel seat as the rotation center, and the upper end of the plate fixing frame will rotate toward the transmission box, so that the photovoltaic panel on the plate fixing frame gradually changes from a horizontal orientation to an upward orientation, and the angle of the photovoltaic panel can be adjusted step by step during the gradual downward movement of the rack.

[0011] Furthermore, it also includes a counterweight component, which includes a loading and unloading seat, a counterweight seat, a counterweight block and a nut. The loading and unloading seat is connected to the rotating seat, and the loading and unloading seat and the transmission box are located on the same side of the rotating seat. The stud on the counterweight seat passes through the counterweight block and the loading and unloading seat in sequence. The nut is screwed on the upper end of the stud and is abutted against the loading and unloading seat.

[0012] Compared with the prior art, the advantage of the utility model is that under the linkage of the axial rotating component and the angle adjustment component, the photovoltaic panels on the fixed panel frame can be adjusted in all directions, thereby adjusting the light-chasing angle of the photovoltaic panels, so that the photovoltaic panels can maintain the best angle toward the sun during operation, thereby achieving maximum power generation efficiency.

The box cover 432 is detachably connected to the base box 431 and covers the movable cavity 433. The transmission box 43 is rotatably connected to one end of the rotating seat 31. The rotating seat 31 is provided with a rotating seat 36. The fixed plate frame 2 is provided with a rotating column 21. The rotating column 21 is matched and connected in the rotating seat 36.

The stud 621 on the counterweight seat 62 passes through the counterweight block 63 and the loading and unloading seat 61 in sequence. The nut 64 is screwed on the upper end of the stud 621 and is abutted against the loading and unloading seat 61.

[0030] Description of the working method of this utility model:

[0031] The bracket adopts this structure to facilitate the adjustment of the photovoltaic panel chasing angle. The bottom of the support frame 1 is installed through the mounting hole 121 on the mounting plate 12, and the anchor screws pre-buried in the mounting position are installed, and the nuts are screwed in to lock them, so as to achieve the installation and fixation of the support frame 1. An axial rotating member 3 is installed at the upper end of the support frame 1, and the upper end of the support frame 1 is embedded in the bearing 34 at the center of the rotating seat 31, so that the rotating seat 31 can be axially rotated with the support frame 1 as the rotation center. In order to achieve the control of the rotation angle, an internal gear 33 is provided at the bottom of the rotating seat 31, and the center of the internal gear 33 coincides with the center of the bearing 34. Then, a rotating motor 32 is installed on the bracket 11 on the support frame 1, and the output end of the rotating motor 32 faces upward and is installed with a first gear 35, which is meshed with the internal gear 33. Therefore, in the process of starting the rotating motor 32 to rotate forward or reverse, the rotating seat 31 can be axially rotated due to the meshing of the first gear 35 with the internal gear 33, so the photovoltaic panel 5 on the fixed plate frame 2 installed on the rotating seat 31 can be axially rotated.

[0032] In order to adjust the angle of the photovoltaic panel 5, a transmission box 43 is connected to one end of the rotating seat 31 in a transmission manner. The transmission box 43 is composed of a base box 431 and a box cover 432. The rack 41 is inserted into the movable cavity 433 that runs through the base box 431 from top to bottom. The second gear 44 on the output end of the push motor 42 outside the base box 431 is meshed with the rack 41 in the movable cavity 433. The setting of the movable cavity 433 can facilitate the addition of lubricating oil here so that the rack 41 can move more smoothly. After the refueling is completed, the box cover 432 is closed on the base box 431 and screwed to lock it, so as to cover the movable cavity 433. Therefore, when the push motor 42 is started, the second gear 44 can drive the rack 41 to move up and down. , and the upper end of the rack 41 is rotatably connected to the upper end of the fixed plate frame 2. Therefore, during the up and down movement of the rack 41, the fixed plate frame 2 can move up and down with the rack 41. Since the lower end of the fixed plate frame 2 is matched with the rotating seat 36 on the rotating seat 31 through the rotating column 21 thereon, when observed from the side perspective, the rack 41, the fixed plate frame 2 and the rotating seat 31 are surrounded by a triangular structure with the rotating seat 31 as the base. Therefore, during the downward movement of the rack 41, the fixed plate frame 2 will take the rotating seat 36 as the rotation center, and the upper end of the fixed plate frame 2 will rotate toward the direction of the transmission box 43, so that the photovoltaic panel 5 on the fixed plate frame 2 gradually changes from a horizontal orientation to an upward orientation, and the angle of the photovoltaic panel 5 can be adjusted step by step during the gradual downward movement of the rack 41.

[0033] Since the photovoltaic panel 5 on the fixed plate frame 2 is heavier than one side of the rotating seat 31, especially when the photovoltaic panel 5 is oriented horizontally, the weight distribution on the rotating seat 31 is extremely uneven. In this case, the rotating seat 31 is rotated by driving the internal gear 33 by the rotating motor 32, which is easy to damage the first gear 35 and the internal gear 33, and the bearing 34. In order to extend the service life of the bracket 11, a counterweight component 6 is added to the rotating seat 31 on the same side as the transmission box 43, and the stud 621 on the counterweight seat 62 sequentially penetrates the counterweight block 63 and the loading and unloading seat 61, a nut 64 is screwed into it to fix the counterweight seat 62. Since the photovoltaic panel 5 itself has various sizes and specifications, the weight of the counterweight also needs to be adjustable. Therefore, the weight can be adjusted by adding the number of counterweight blocks 63. The detachable structure can also facilitate the assembly workers to make adjustments. Therefore, after adding the counterweight component 6, the weight on the rotating seat 31 can be balanced. Even if the photovoltaic panel 5 is pointing upward, this state is maintained for a very short time. Moreover, the weight of the flat photovoltaic panel 5 is relatively even, and the addition of the counterweight block 63 will not cause wear and loss.

[0034] Since the photovoltaic light-chasing sampling is carried out through another set of equipment for data output, and the data is used to adjust the rotation direction and angle of the photovoltaic panel through a computer, this part belongs to the existing technology and will not be elaborated here on how to collect the light-chasing data and how to provide data operation.

[0035] The beneficial effect of the utility model is that under the linkage of the axial rotating component 3 and the angle adjustment component 4, the photovoltaic panel 5 on the fixed plate frame 2 can be adjusted in all directions, so as to adjust the light-chasing angle of the photovoltaic panel 5, so that the photovoltaic panel 5 can maintain the best angle facing the sun during operation, thereby achieving maximum power generation efficiency. The increased breeding component can achieve left and right weight balance adjustment on the rotating seat 31 by adding a number of counterweight blocks 63, and the detachable structure can also facilitate adjustment by the assembly workers, reducing the uneven weight distribution on the rotating seat 31, which causes the rotation of the rotating seat 31 driven by the internal gear 33 to damage the first gear 35 and the internal gear 33 and the bearing 34, thereby extending the service life of the bracket.

[0036] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
