Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation, and more particularly to a photovoltaic power generation device with a module snap-fit ​​installation structure. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It mainly consists of three parts: solar panels (modules), a controller, and an inverter. The main components are made up of electronic components. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with components such as power controllers, this forms a photovoltaic power generation device.

[0003] When installing existing photovoltaic power generation devices, the mounting frame needs to be fixed in advance before the photovoltaic solar panels are placed on the mounting frame. Since the mounting frame is set at an angle, installers need to help to support the photovoltaic solar panels on the mounting frame and place them in the corresponding positions. Then, multiple sets of fixing bolts are used to fix the photovoltaic solar panels to the mounting frame. This traditional installation method requires the cooperation of multiple installers to complete the installation, and the installation process is time-consuming and labor-intensive.

[0012] Compared with related technologies, the photovoltaic power generation device with a component snap-fit ​​installation structure provided by the present invention has the following beneficial effects:

[0013] 1. This invention provides a photovoltaic power generation device with a component snap-fit ​​installation structure. By inserting the vertical plates at both ends of the main plate into the insertion slots on two horizontal plates, the main plate is hung on the mounting frame. Rotating the manual valve causes the mounting plate to slide relative to the curved tube, venting the gas inside the curved tube into the two first small cylindrical grooves. This allows one end of each of the two plug-in sliding bolts to slide into the two first fixing grooves, thus enabling the photovoltaic panel to slowly and automatically rotate and adjust to an inclined state while simultaneously completing the convenient pre-fixing between the main plate and the mounting frame. The entire installation process does not require manual support from the installer, making it very convenient.

[0014] 2. This invention provides a photovoltaic power generation device with a component snap-fit ​​installation structure. The convex plate at one end of the mounting plate enters the interface of the bottom block at one end of the mounting frame. The second spring restores its elastic deformation and pushes one end of the inclined sliding bolt into the second fixing groove. This allows for automatic and rapid secondary snap-fit ​​fixing after placement, thereby ensuring sufficient stability between the photovoltaic panel and the main board.

[0015] 3. This invention provides a photovoltaic power generation device with a component snap-fit ​​installation structure. By rotating the handle at one end of the rotating shaft, the connecting block on the rotating shaft drives the top rod to slide in the slide groove. The top air piston at one end of the top rod slides inside the inner cylinder, allowing the gas inside the inner cylinder to flow into the inner cavity of the second small cylinder. The increased air pressure can prevent the inclined head sliding bolt from sliding in the opposite direction, thereby ensuring that the locking between the photovoltaic panel and the mounting frame is secure enough. Fixed installation can be completed without the need for multiple sets of fixing bolts, bringing convenience to the installation personnel. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1 to 7 A photovoltaic power generation device with a component snap-fit ​​installation structure includes: a base 1, an installation frame 2 fixedly connected to the base 1, two horizontal plates 21 fixedly connected between the inner frame walls of the installation frame 2, a snap-fit ​​main plate 3 on the installation frame 2, vertical plates 31 fixedly connected to both ends of the snap-fit ​​main plate 3, each of the two horizontal plates 21 having a hanging port, the two vertical plates 31 being slidably connected to the hanging ports on the two horizontal plates 21 respectively, and an installation plate 4 rotatably connected to one end of the snap-fit ​​main plate 3, on which a photovoltaic panel 41 is installed and connected.

[0026] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the inner walls of the two insertion ports are provided with first fixing grooves. A pre-locking mechanism 5 is provided between the two vertical plates 31 and the main plate 3. The pre-locking mechanism 5 includes a bent tube 51. One end of the bent tube 51 is fixedly connected to the main plate 3. An arc rod 52 is slidably connected to the bent tube 51. One end of the arc rod 52 is fixedly connected to the lower end face of the mounting plate 4. The other end of the arc rod 52 is fixedly connected to the main piston 521. The lower end of the bent tube 51 is provided with an extension port 53. A manual valve 531 is installed and connected at the extension port 53. One end of the extension port 53 is fixedly connected to a connecting long tube 54. The two vertical plates 31 are provided with first small cylindrical grooves. The two first small cylindrical grooves are provided with snap-fit ​​components. The main plate 3 is provided with a double-outlet pipe 541. One end of the connecting long tube 54 is connected to the middle of the double-outlet pipe 541. The two ends of the double-outlet pipe 541 extend into the interior of the two first small cylindrical grooves respectively.

[0027] It should be noted that: the main board 3 is hung on the mounting bracket 2. When the manual valve 531 is turned, the extension port 53 at one end of the bend 51 is opened. The photovoltaic panel 41 drives the mounting plate 4 to rotate relative to the main board 3. The mounting plate 4 drives the arc rod 52 to slide relative to the bend 51, which drives the main piston 521 to slide inside the bend 51. The gas inside the bend 51 is slowly discharged through the extension port 53, so that the photovoltaic panel 41 can slowly and automatically rotate and adjust to the tilt state.

[0028] refer to Figure 2 and Figure 3 As shown, the snap-fit ​​assembly includes a first inner ring 55, which is fixedly connected to the inner wall of the first small cylindrical groove. A plug-in bolt 56 is slidably connected to the first inner ring 55. A first piston 561 is fixedly connected to one end of the plug-in bolt 56. A first spring 57 is sleeved on the plug-in bolt 56. One end of the first spring 57 is connected to the first inner ring 55, and the other end of the first spring 57 is connected to the first piston 561.

[0029] It should be noted that the gas inside the bend 51 is discharged through the extension port 53 to the inside of the connecting long pipe 54, then transported to the inside of the double outlet pipe 541, and then dispersed to the inside of the first small cylindrical groove on the two vertical plates 31.

[0030] The increased air pressure inside the two first small cylindrical grooves causes the two first pistons 561 to slide inside the two first small cylindrical grooves. The two first small pistons 561 drive the two plug-in sliding bolts 56 to slide relative to the two first inner rings 55, causing the two first springs 57 to undergo elastic deformation. One end of the two plug-in sliding bolts 56 slides into the two first fixed grooves respectively, thus realizing convenient pre-fixation between the main board 3 and the mounting bracket 2.

[0031] refer to Figure 1 and Figure 4 As shown, the lower end of the mounting bracket 2 is provided with a bottom block 22, and the bottom block 22 is provided with a mating interface. The inner wall of the mating interface is provided with a second fixing groove. One end of the mounting plate 4 is provided with a protruding plate 42, and the protruding plate 42 is provided with a second small cylindrical groove. The second small cylindrical groove is provided with a snap-fit ​​locking mechanism 6. The snap-fit ​​locking mechanism 6 includes a second inner ring 61, which is fixedly connected to the inner wall of the second small cylindrical groove. A slanted head slide bolt 62 is slidably connected to the second inner ring 61. One end of the slanted head slide bolt 62 is designed with a slant. A second piston 621 is fixedly connected to one end of the slanted head slide bolt 62. A second spring 63 is sleeved on the slanted head slide bolt 62. One end of the second spring 63 is connected to the second piston 621, and the other end of the second spring 63 is connected to the second inner ring 61. One end of the mounting plate 4 is provided with an embedded long tube 64, and one end of the embedded long tube 64 extends into the second small cylindrical groove.

[0032] It should be noted that when the photovoltaic panel 41 is rotated to the same tilt angle as the mounting frame 2, the protruding plate 42 at one end of the mounting plate 4 enters the bottom block 22 at one end of the mounting frame 2. When the inclined surface at one end of the inclined head slide bolt 62 abuts against the bottom block 22, the inclined head slide bolt 62 slides relative to the second inner ring 61. The inclined head slide bolt 62 drives the second piston 621 to slide, causing the second spring 63 to undergo elastic deformation.

[0033] Until the convex plate 42 is fully inserted into the mating interface on the bottom block 22, the second spring 63 restores its elastic deformation and pushes one end of the inclined head slide bolt 62 into the second fixing groove. This allows for automatic secondary quick snap-fit ​​fixing after placement, ensuring sufficient stability between the photovoltaic panel 41 and the main board 3.

[0034] refer to Figure 5 and Figure 6 As shown, one end of the mounting plate 4 is provided with a long groove, and the inside of the long groove is provided with an air injection safety mechanism 7. The air injection safety mechanism 7 includes an inner cylinder 71, which is fixedly installed in the long groove. A push rod 72 is slidably connected to one end of the inner cylinder 71. A push piston 721 is fixedly connected to one end of the push rod 72. A sliding groove is provided at one end of the long groove, and the push rod 72 is slidably connected to the sliding groove. A connecting hole shell 73 is provided at one end of the inner cylinder 71. A short connecting pipe 74 is fixedly connected to the connecting hole shell 73. The other end of the short connecting pipe 74 is fixedly connected to the opening of the embedded long pipe 64. A one-way valve 75 is provided in the middle of the short connecting pipe 74.

[0035] It should be noted that: the top air piston 721 slides inside the inner cylinder 71, and discharges other contents inside the inner cylinder 71 through the connecting hole shell 73, and then flows through the short pipe 74 to the inside of the embedded long pipe 64. The air pressure in the second small cylinder groove increases, which can hold the top air piston 721 in place and prevent the top air piston 721 from sliding in the opposite direction with the inclined head slide bolt 62.

[0036] refer to Figure 1 and Figure 7 As shown, the other end of the mounting plate 4 is provided with a control mechanism 8. The control mechanism 8 includes a long strip plate 81, which is fixedly connected to the side wall of the mounting plate 4. A rotating shaft 82 is rotatably connected to the long strip plate 81. A connecting block 83 is provided on the rotating shaft 82. The connecting block 83 is provided with a threaded opening. The rotating shaft 82 is a threaded shaft. The connecting block 83 is threadedly connected to the rotating shaft 82. The connecting block 83 is fixedly connected to one end of the top rod 72. A small side block 831 is provided on the connecting block 83. A long limiting groove is provided on the long strip plate 81. The small side block 831 is located in the long limiting groove. A rotating handle 84 is fixedly connected to one end of the rotating shaft 82.

[0037] It should be noted that: rotating the handle 84 at one end of the rotating shaft 82 causes the connecting block 83 on the rotating shaft 82 to move relative to each other. The connecting block 83 drives the small side block 831 to slide in the long limiting groove on the long strip plate 81. The connecting block 83 drives the push rod 72 to slide in the sliding groove, so that the top air piston 721 at one end of the push rod 72 slides inside the inner cylinder 71.

[0038] The working principle of a photovoltaic power generation device with a component snap-fit ​​installation structure provided by the present invention is as follows: After the mounting frame 2 is fixedly installed, the snap-fit ​​main board 3 is placed on the mounting frame 2, so that the vertical plates 31 at both ends of the snap-fit ​​main board 3 are respectively inserted into the insertion holes on the two horizontal plates 21, so that the snap-fit ​​main board 3 is hung on the mounting frame 2. The manual valve 531 is turned so that the extension port 53 at one end of the bent tube 51 is in the open state. The photovoltaic panel 41 drives the mounting plate 4 to rotate relative to the snap-fit ​​main board 3. The mounting plate 4 drives the arc rod 52 to slide relative to the bent tube 51, and drives the main piston 521 to slide inside the bent tube 51, so that the gas inside the bent tube 51 is slowly discharged through the extension port 53, so that the photovoltaic panel 41 is slowly and automatically tilted.

[0039] The gas inside the bend 51 is discharged through the extension port 53 to the inside of the connecting long pipe 54, and then transported to the inside of the double outlet pipe 541. After that, it is dispersed into the inside of the first small cylindrical grooves on the two vertical plates 31. The gas pressure inside the two first small cylindrical grooves increases, causing the two first pistons 561 to slide inside the two first small cylindrical grooves. The two first small pistons 561 drive the two plug-in sliding bolts 56 to slide relative to the two first inner rings 55, causing the two first springs 57 to undergo elastic deformation. One end of the two plug-in sliding bolts 56 slides into the two first fixing grooves respectively, which can realize convenient pre-fixation between the main board 3 and the mounting bracket 2. The installation of the entire photovoltaic device can be completed quickly without the need for manual support by the installer.

[0040] When the photovoltaic panel 41 rotates to the same tilt angle as the mounting bracket 2, the protruding plate 42 at one end of the mounting plate 4 enters the bottom block 22 at one end of the mounting bracket 2. When the inclined surface of one end of the inclined head slide bolt 62 abuts against the bottom block 22, the inclined head slide bolt 62 slides relative to the second inner ring 61. The inclined head slide bolt 62 drives the second piston 621 to slide, causing the second spring 63 to undergo elastic deformation until the protruding plate 42 is completely inserted into the mating interface on the bottom block 22. The second spring 63 then restores its elastic deformation, pushing one end of the inclined head slide bolt 62 to slide into the second fixing groove. This allows for automatic secondary quick snap-fit ​​fixing after placement, ensuring sufficient stability between the photovoltaic panel 41 and the main mounting plate 3.

[0041] Rotating the handle 84 at one end of the rotating shaft 82 causes the connecting block 83 on the rotating shaft 82 to move relative to it. The connecting block 83 drives the small side block 831 to slide in the long limiting groove on the long strip plate 81. The connecting block 83 drives the top rod 72 to slide in the sliding groove, causing the top air piston 721 at one end of the top rod 72 to slide inside the inner cylinder 71. Other air inside the inner cylinder 71 is discharged through the connecting hole shell 73 and then flows through the short pipe 74 to the inside of the embedded long pipe 64. The air pressure in the second small cylinder groove increases, which can hold the top air piston 721 in place and prevent the top air piston 721 from sliding in the opposite direction with the inclined head sliding bolt 62. This ensures that the locking between the photovoltaic panel 41 and the mounting frame 2 is secure enough, and the fixed installation can be completed without the use of multiple sets of fixing bolts, which brings convenience to the installers.
