Description

Technical Field

[0001] The invention belongs to the technical field of solar photovoltaic panel frame components, and in particular relates to a combined solar photovoltaic panel frame component. Background Art

[0002] Solar photovoltaic panels refer to facilities that use the photovoltaic effect of photovoltaic semiconductor materials to convert solar energy into direct current electricity. The core of photovoltaic facilities is solar panels, which absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through photoelectric effect or photochemical effect. The main material of most solar panels is "silicon", which is brittle and expensive, so its frame must be fixed during the actual installation process.

[0003] At present, most photovoltaic module manufacturers use aluminum alloy as the material of the outer frame, because aluminum alloy has the characteristics of high strength, easy shaping, excellent anti-corrosion performance, etc., which can meet the needs of photovoltaic modules. However, the ultimate goal of photovoltaic power generation is to achieve grid parity, and the cost of aluminum alloy frames is still relatively high. The industry has also tried to use steel frames to replace aluminum alloy frames to reduce costs, but the steel structure frame is heavy, and it is not convenient to lift and lower the solar photovoltaic panels during use, and adjust the angle, which will greatly consume the workers' time. Therefore, in order to promote photovoltaic power generation and make it popular, while reducing costs, it is also necessary to make photovoltaic modules easy to use and adjust in daily use.

[0004] Therefore, those skilled in the art provide a combined solar photovoltaic panel frame assembly to solve the problems raised in the above background technology. Summary of the invention

[0005] The purpose of the present invention is to provide a frame assembly of a combined solar photovoltaic panel with a simple structure and reasonable design in order to solve the above problems.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0007] A frame assembly of a combined solar photovoltaic panel, comprising a steel structure frame arranged on the outer circle of the photovoltaic panel, and a rotating mechanism with an adjustable angle is arranged between two of the steel structure frames;

[0012] As a further optimization solution of the present invention, a height adjustment mechanism is provided at the bottom of the frame base.

[0013] As a further optimization scheme of the present invention, the height adjustment mechanism includes a driving assembly, a telescopic foot, and a connecting rod. The telescopic foot is vertically installed, one end of the connecting rod is movably connected to the telescopic foot, and the other end of the connecting rod is movably connected to the output end of the driving assembly. The driving assembly drives the end of the connecting rod connected thereto to move horizontally.

[0014] As a further optimization scheme of the present invention, the driving assembly includes a dual-axis motor, both output ends of the dual-axis motor are horizontally provided with screw rods, a movable sleeve is threadedly connected to the screw rods, and the thread directions of the outer surfaces of the two screw rods are arranged in opposite directions.

[0026] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Example 1

[0028] like Figure 1-5 As shown, a frame assembly of a combined solar photovoltaic panel includes a steel structure frame 2 arranged on the outer circle of a photovoltaic panel 1, and an adjustable angle rotating mechanism 3 is arranged between the two steel structure frames 2;

[0029] The photovoltaic panels in the existing photovoltaic modules generally have no tilt angle and are arranged parallel to the cover plate of the module. However, if the photovoltaic module is laid flat, its power generation efficiency is low; in order to improve the power generation efficiency, the tilt angle of the photovoltaic module is determined according to the on-site terrain, and an adjustable angle bracket is installed, which has great application prospects. In this application, an adjustable angle rotating mechanism 3 is provided between the two steel structure frames 2, so that the two photovoltaic panels arranged side by side can face different directions respectively, and the angle is adjustable, thereby improving the efficiency of energy conversion of the photovoltaic panel.

[0030] The lower end of the steel structure frame 2 is movably provided with a frame base 5 that cooperates with the steel structure frame 2 to rotate;

[0031] The rotating mechanism 3 includes an annular protrusion 31 and an annular groove 32 that are plugged into each other. A stop block 311 is provided on the outer wall of the annular protrusion 31. A threaded hole 312 is provided on the annular protrusion 31. A stop groove 321 that matches the stop block 311 is provided on the annular groove 32. Countersunk screws 322 that can be rotatably locked are arranged at both ends of the stop groove 32. When the distance between the two frames needs to be adjusted, the stop block 311 on the annular protrusion 31 and the upper stop groove 321 on the stop groove 32 are adjusted by rotating and pulling out the countersunk screws 322, so that the angle of the two steel structure frames 2 can be adjusted. At the same time, the plugging of the stop block 311 and the stop groove 321, as well as the locking of the countersunk screws 322, make the connection between the two steel structure frames 2 more secure, which can cope with various outdoor environments.

[0032] Specifically, the frame base 5 is annular, a pulley 21 is provided at the bottom of the steel structure frame 2, and an annular groove is provided in the frame base 5 to cooperate with the rotation of the pulley 21. When the orientation of the photovoltaic panel needs to be adjusted, the pulley 21 can slide in the annular groove to adjust the angle between the two steel structure frames 2.

[0033] Specifically, through grooves 53 are provided on the front and rear sides of the frame base 5, and fastening bolts 57 are arranged on the front and rear end faces of the frame base 5. The fastening bolts 57 pass through the through grooves 53 to lock the pulley 21. The pulley 21 and the annular groove can be locked by the fastening bolts 57, which effectively prevents the steel structure frame 2 from moving in strong winds outdoors, thereby reducing the efficiency of energy conversion of the photovoltaic panel.

[0034] Specifically, a height adjustment mechanism is provided at the bottom of the frame base 5 .

[0035] Specifically, the height adjustment mechanism includes a driving assembly, a telescopic foot 51, and a connecting rod 52. The telescopic foot 51 is vertically installed, one end of the connecting rod 52 is movably connected to the telescopic foot 51, and the other end of the connecting rod 52 is movably connected to the output end of the driving assembly. The driving assembly drives the end of the connecting rod 52 connected thereto to move horizontally.

[0036] It should be noted that the telescopic foot 51 is designed as a telescopic rod structure, which plays a role in supporting the device body and also makes the height of the device body adjustable.

[0037] Specifically, the driving assembly includes a dual-axis motor 54, and both output ends of the dual-axis motor 54 are horizontally arranged with screw rods 55, and a movable sleeve 56 is threadedly connected to the screw rods 55. The thread directions of the outer surfaces of the two screw rods 55 are arranged in opposite directions. When the dual-axis motor 54 is working, the two screw rods 55 drive the movable sleeve 56 to move. Since the thread directions of the outer surfaces of the two screw rods 55 are arranged in opposite directions, the two movable sleeves 56 move relative to or towards each other.

[0038] It should be noted that the dual-axis motor 54 is a forward and reverse motor, and the motor model may be Y90S-4.

[0039] Specifically, two ends of the connecting rod 52 are hinged to the telescopic foot 51 and the movable sleeve 56 respectively.

[0040] This arrangement can be used in different installation scenarios. By driving the dual-axis motor 54 to work, when the two movable sleeves 56 move relative to each other, the connecting rod 52 drives the foot 51 to rise, thereby raising the steel structure frame 2 to adapt to various outdoor use environments. This makes the entire device more flexible to use, and does not cause workers to waste a lot of time and be inconvenient to use during daily use due to the heavy weight of the steel structure frame 2.

[0041] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
