[0002] With the general trend of the modern energy structure gradually shifting towards renewable energy, photovoltaic power generation, as a clean and sustainable way of obtaining energy, has been widely used and promoted, especially rooftop photovoltaic power generation, which is becoming increasingly popular in residential and commercial buildings.

[0003] However, existing rooftop photovoltaic (PV) frames have some problems in practical applications: 1. During installation, traditional rooftop PV frames are often difficult to adjust flexibly according to the actual tilt angle of the roof and the size of different PV modules. Installers need to spend a lot of time and energy on-site adjustments, which not only increases installation costs but may also lead to unstable installation of PV modules due to improper adjustment, affecting overall stability and safety; 2. PV modules need to be firmly installed on the roof to resist the effects of natural factors such as wind and rain. The connection method of traditional frame aluminum profiles is not stable enough, which can easily lead to loosening of PV modules during long-term use, affecting power generation efficiency and system safety. Utility Model Content

[0004] The main objective of this invention is to provide a lightweight aluminum profile for rooftop photovoltaic frames, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A lightweight rooftop photovoltaic frame aluminum profile includes a lower H-shaped vertical beam. The upper front end of the lower H-shaped vertical beam has a first threaded hole that passes through the front and rear. An adjustment device is threaded into the first threaded hole. The adjustment device is movably connected to a connecting device. Drainage frames are fixedly connected to the lower front end and the lower rear end of the connecting device. Water collection troughs are formed on the outer sides of the two drainage frames. Several arc-shaped drainage pipes are fixedly connected to the lower inner wall of the two water collection troughs.

[0007] The adjusting device includes a mounting plate, the lower end of which is fixedly connected to two clamping plates. The two clamping plates are connected together by a first screw. The front and rear outer surfaces of the first screw are threaded with a first fastening nut. The front and rear upper ends of the mounting plate are fixedly connected to side plates. The two side plates are connected together by a second screw. The front and rear outer surfaces of the second screw are threaded with a second fastening nut.

[0008] Preferably, the lower end face of the mounting plate is in contact with the upper end of the lower H-shaped vertical beam, the two clamping plates are symmetrically distributed on both sides of the first threaded hole, and the first screw passes through the two clamping plates and is fully engaged with the internal thread of the first threaded hole.

[0009] Preferably, the connecting device includes an upper H-shaped crossbeam, the upper H-shaped crossbeam having a hollow cavity, a plurality of reinforcing ribs being fixedly connected in the hollow cavity, and movable heads being fixedly connected to the left front end and the rear front end of the upper H-shaped crossbeam, with a second threaded hole being formed on the inner surface of each of the two movable heads.

[0010] Preferably, the outer surfaces of the two movable heads are movably connected to the inner surfaces of the two side plates.

[0011] Preferably, the two ends of the plurality of reinforcing ribs are welded and fixed to the upper and lower inner walls of the hollow cavity, and the plurality of reinforcing ribs are distributed at equal intervals.

[0012] Preferably, the second screw is threadedly connected to the second threaded hole in the two movable heads.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the adjustment device can be flexibly adjusted according to the actual tilt angle of the roof and the size of different photovoltaic modules. Through the structural design of the cooperation between the first screw and the first threaded hole and the cooperation between the second screw and the second threaded hole, the connection angle and position between the mounting plate and the lower H-shaped vertical beam, and between the connecting device and the adjustment device can be adjusted. This solves the problem that traditional roof photovoltaic frames are difficult to adjust flexibly, reduces the time and effort of installers to adjust on-site, lowers the installation cost, and also avoids the situation of photovoltaic modules not being installed firmly due to improper adjustment, thus improving the overall stability and safety.

[0016] 2. In this utility model, the device achieves a more stable connection through the design of a series of structures such as the lower H-shaped vertical beam, the adjustment device, and the connection device. For example, the mounting plate is connected to the lower H-shaped vertical beam through the clamping plate, the first screw, and the first fastening nut. The movable head of the connection device is connected to the side plate of the adjustment device through the second screw and the second fastening nut. This multi-component connection method is more stable than the traditional frame aluminum profile connection method, and can effectively resist the influence of natural factors such as wind and rain, reduce the possibility of loosening of photovoltaic modules during long-term use, and thus ensure power generation efficiency and system safety.

[0026] A lightweight roof photovoltaic frame aluminum profile includes a lower H-shaped vertical beam 1. The upper front end of the lower H-shaped vertical beam 1 has a first threaded hole 2 that passes through the front and rear. An adjustment device 3 is internally threaded into the first threaded hole 2. The adjustment device 3 is movably connected to a connecting device 4. Drainage frames 5 are fixedly connected to the lower front end and the lower rear end of the connecting device 4. Water collection troughs 6 are opened on the outer sides of the two drainage frames 5. Several arc-shaped drainage pipes 7 are fixedly connected to the lower inner wall of the two water collection troughs 6.

[0027] In this embodiment, the adjusting device 3 includes a mounting plate 31. Two clamping plates 32 are fixedly connected to the lower end of the mounting plate 31. A first screw 33 is inserted through the two clamping plates 32. A first fastening nut 34 is threadedly connected to both the front and rear parts of the outer surface of the first screw 33. Side plates 35 are fixedly connected to both the front and rear parts of the upper end of the mounting plate 31. A second screw 36 is inserted through the two side plates 35. A second fastening nut 37 is threadedly connected to both the front and rear parts of the outer surface of the second screw 36. The lower end face of the mounting plate 31 is in contact with the upper end of the lower H-shaped vertical beam 1. The two clamping plates 32 are symmetrically distributed on both sides of the first threaded hole 2. After the first screw 33 passes through the two clamping plates 32, it is completely engaged with the internal thread of the first threaded hole 2. The outer surfaces of the two movable heads 44 are movably connected to the inner surfaces of the two side plates 35. The second screw 36 is threadedly connected to the second threaded hole 45 in the two movable heads 44.

[0028] Through the above scheme: the mounting plate 31 is secured to both sides of the first threaded hole 2 by the clamping plate 32, the first screw 33 passes through the clamping plate 32 and is screwed into the first threaded hole 2 to complete the fixation, the upper H-shaped crossbeam 41 is movably connected to the side plate 35 through the movable head 44, the second screw 36 passes through the side plate 35 and is screwed into the second threaded hole 45 of the movable head 44, the angle of the upper H-shaped crossbeam 41 is adjusted by rotating the two movable heads 44, and the threaded engagement of the first screw 33 with the first threaded hole 2, the second screw 36 with the second threaded hole 45, and the locking effect of the first fastening nut 34 and the second fastening nut 37 ensure that the connection is stable and can be flexibly adjusted as needed.

[0029] In this embodiment, the connecting device 4 includes an upper H-shaped crossbeam 41, a hollow cavity 42 is formed inside the upper H-shaped crossbeam 41, and several reinforcing ribs 43 are fixedly connected inside the hollow cavity 42. Movable heads 44 are fixedly connected to the left front end and the rear front end of the upper H-shaped crossbeam 41. The inner surfaces of the two movable heads 44 are provided with second threaded holes 45. The outer surfaces of the two movable heads 44 are movably connected to the inner surfaces of the two side plates 35. The two ends of the several reinforcing ribs 43 are welded and fixed to the upper and lower inner walls of the hollow cavity 42, and the several reinforcing ribs 43 are distributed at equal intervals. The upper ends of several arc-shaped drain pipes 7 are integrally formed with the lower inner walls of the two water collection tanks 6, and the lower ends of the several arc-shaped drain pipes 7 extend to the outer side of the two drain frames 5, respectively. The diameter of the several arc-shaped drain pipes 7 gradually increases from the upper end to the lower end.

After the second fastening nut 37 is loosened, the movable head 44 can rotate around the second screw 36, driving the upper H-shaped crossbeam 41 to adjust the pitch angle to adapt to different roof tilt angles. The reinforcing ribs 43 in the hollow cavity 42 are evenly distributed and welded to the upper and lower inner walls to form a honeycomb support structure. This design reduces the weight of the profile while improving the bending strength through the principle of triangular stability, ensuring that the photovoltaic modules will not deform under long-term load. After the water collection tank 6 collects rainwater, it is discharged through the arc-shaped drainage pipe 7. The design of the pipe diameter gradually expanding from top to bottom uses the Venturi effect to accelerate the water flow and avoid water accumulation.

[0031] It should be noted that this utility model is a lightweight roof photovoltaic frame aluminum profile. In the process of use, firstly, the lower H-shaped vertical beam 1 is fixed to the roof foundation structure. The mounting plate 31 is clamped on both sides of the first threaded hole 2 by the clamping plate 32. The first screw 33 passes through the clamping plate 32 and is screwed into the first threaded hole 2 to initially fix the adjustment device 3. Then, the outer side of the movable head 44 of the connecting device 4 is attached to the inner side of the side plate 35. The second screw 36 passes through the side plate 35 and is screwed into the second threaded hole 45 of the movable head 44 to initially connect the upper H-shaped crossbeam 41 with the adjustment device 3. According to the photovoltaic module installation requirements, the second fastening nut 37 is loosened, the movable head 44 is rotated to adjust the angle of the upper H-shaped crossbeam 41 and then locked. Finally, rainwater is collected through the water collection trough 6 on the drainage frame 5 and discharged through the arc-shaped drainage pipe 7. The reinforcing ribs 43 in the hollow cavity 42 of the upper H-shaped crossbeam 41 ensure the structural strength and ensure the stable operation of the device.
