[0002] A photovoltaic module is an assembly assembled by multiple solar cells, which is the core part and the most important part in a solar power generation system. In order to improve the photoelectric conversion efficiency, generally, the inclination angle of the photovoltaic module is designed to be adjustable to adjust the solar angle according to the change of the solar altitude in different seasons.

[0003] The existing photovoltaic modules with adjustable inclination angles generally consist of structures such as threaded rods, threaded sleeves, and support rods.

Detailed implementation mode

[0022] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0023] Embodiment 1: Please refer to Figures 1-7 , the present utility model provides a technical solution: a photovoltaic module with adjustable inclination angle, including a base 1. Two first support rods 2 are hinged on the threaded sleeve of the base 1. The first support rods 2 are used to support the base 1. An inner part of the first support rod 2 is hinged with a mounting block 3. The first support rod 2 plays a limiting role on the mounting block 3, enabling the mounting block 3 to rotate smoothly. A bottom end of the mounting block 3 is fixedly connected with an insert block 4. An outer part of the insert block 4 is inserted with a second support rod 5. The insert block 4 is used to connect the mounting block 3 and the second support rod 5, and enables the mounting block 3 and the second support rod 5 to be disassembled conveniently. A bottom end of the mounting block 3 is in contact with a top end of the second support rod 5, so that the connection between the mounting block 3 and the second support rod 5 is relatively stable. An inner part of the second support rod 5 is provided with a placing groove 6. The placing groove 6 is designed in a "U" shape. An inner part of the placing groove 6 is slidably connected with a third support rod 7. The third support rod 7 is adapted to the placing groove 6. The placing groove 6 plays a limiting role on the third support rod 7, enabling the third support rod 7 to slide smoothly, and the placing groove 6 is used to accommodate the third support rod 7, so that the second support rod 5 and the third support rod 7 can enter the inner part of the first support rod 2. An inner part of a bottom end of the third support rod 7 is inserted with a plug pin 19. The plug pin 19 is inserted into the base 1. The plug pin 19 penetrates through the third support rod 7 and is inserted into the base 1, so that the positions of the insert block 4 and the third support rod 7 are restricted, and thus the base 1 is more stable when adjusting the inclination angle.

[0024] When the support rod three 7 and the insertion block 4 need to be used, the insertion block 4 is rotated out from the inside of the support rod one 2, and then the support rod three 7 is pulled downward, so that the support rod three 7 can slide downward inside the placement groove 6. Then, the pin 19 is passed through the support rod three 7 and inserted into the inside of the base 1, so as to fix the position of the support rod three 7 and the support rod two 5, and then the support rod one 2 can be supported. Thus, the support rod one 2, the support rod two 5 and the support rod three 7 can jointly support the base 1. And when the support rod two 5 needs to be replaced, by pulling the support rod two 5 downward, the support rod two 5 can be separated from the insertion block 4. On the contrary, by pushing the support rod two 5 upward, the support rod two 5 can slide with the insertion block 4 and squeeze the insertion block 4 to deform. Then, when the top end of the support rod two 5 fits with the bottom end of the insertion block 4, the support rod two 5 can be conveniently installed. This not only makes the support more stable, but also makes the inclination adjustment more convenient, so as not to affect the photoelectric conversion efficiency, and thus makes the use economy better.

[0025] Embodiment 2: On the basis of Embodiment 1, in order to make the support rod three 7 slide more stably, a limiting groove 9 is opened on the inner wall of the placement groove 6. A limiting block 8 is slidably connected inside the limiting groove 9. The limiting groove 9 plays a limiting role on the limiting block 8, so that the limiting block 8 will not deviate when sliding. One end of the limiting block 8 away from the limiting groove 9 is fixedly connected to the support rod three 7.

[0026] When the support rod three 7 needs to slide inside the placement groove 6, the limiting block 8 can slide inside the limiting groove 9. Then, the support rod three 7 can be limited by the limiting block 8 and the placement groove 6, so that the support rod three 7 will not deviate when sliding.

[0027] Embodiment 3: On the basis of Embodiment 2, in order to limit the support rod three 7 after it is drawn out from the inside of the placement groove 6, two installation grooves 14 are opened inside the support rod three 7. An elastic member 15 is fixedly connected to the inner wall of the installation groove 14. The other end of the elastic member 15 is fixedly connected to an installation piece 16. The installation piece 16 is slidably connected inside the installation groove 14. The installation groove 14 plays a limiting role on the installation piece 16 inside, so that the installation piece 16 can slide smoothly. One end of the installation piece 16 away from the elastic member 15 is fixedly connected to a push rod 17. The push rod 17 is slidably connected inside the installation groove 14. The installation groove 14 plays a limiting role on the push rod 17, so that the push rod 17 will not deviate when moving. One end of the push rod 17 away from the installation piece 16 is designed as an arc, so that the push rod 17 can slide on the inner wall of the placement groove 6. A plurality of card slots 18 are opened on both sides of the support rod two 5. The plurality of card slots 18 are equidistantly distributed. The push rod 17 is engaged with the card slots 18, so as to limit the support rod three 7.

[0028] When it is necessary to pull the third support rod 7, by pushing the two push rods 17 towards the closer side, the push rod 17 can then push the mounting piece 16 towards the inner end. And when the arc of the push rod 17 enters the inside of the clamping groove 18, by pulling the third support rod 7 downward, the third support rod 7 can drive the push rod 17 to move downward, so that the arc of the push rod 17 can slide on the inner wall of the second support rod 5. Then when the push rod 17 is in a horizontal position with the next clamping groove 18, the elastic member 15 can perform a reset movement, and then the elastic member 15 can push the mounting piece 16 to move outward, so that the mounting piece 16 can push the push rod 17 to engage with the clamping groove 18, thereby being able to limit the third support rod 7. Repeat the above operation until the third support rod 7 extends out of the placement groove 6 by the required distance.

[0029] Embodiment 4: On the basis of Embodiment 3, in order to make the sliding of the third support rod 7 more convenient, a sliding groove 13 is opened on the upper side of the mounting groove 14. The sliding groove 13 is connected to the inside of the limiting groove 9, so that the lubricating oil inside the sliding groove 13 can flow into the inside of the limiting groove 9, and then can flow into the inside of the placement groove 6. The top end of the mounting piece 16 is fixedly connected with a sliding block 11. The sliding block 11 is slidably connected to the inside of the sliding groove 13. The sliding groove 13 plays a role in limiting the sliding block 11, so that the sliding block 11 will not deviate during sliding, and the sliding block 11 can block the communication between the sliding groove 13 and the oil groove 10, so that the lubricating oil will not drip when not in use. The lower side of the sliding block 11 is slidably connected to the inside of the mounting groove 14. The mounting groove 14 plays a role in limiting the sliding block 11, so that the sliding block 11 will not deviate during sliding. A communication groove 12 is opened inside the sliding block 11. The inner side of the communication groove 12 is connected to the sliding groove 13, so that after the sliding block 11 moves, the lubricating oil can flow into the inside of the sliding groove 13 through the communication groove 12. An oil groove 10 is opened on the upper side of the inner wall of the sliding groove 13. The oil groove 10 is used to store lubricating oil. The top end of the communication groove 12 is connected to the oil groove 10, so that the lubricating oil inside the oil groove 10 can flow into the inside of the communication groove 12. A sealing plug 20 is fixedly connected to the inside of the top end of the third support rod 7. The sealing plug 20 is used to seal the oil filling port of the oil groove 10. When the top end of the third support rod 7 fits against the upper side of the inner wall of the placement groove 6, the oil injection pipe on the second support rod 5 can be inserted into the inside of the sealing plug 20, and then the inside of the oil groove 10 can be filled with lubricating oil.

[0030] Since the inclination angle of the photovoltaic module is adjusted according to seasons, the positions of the first support rod 2, the third support rod 7, and the second support rod 5 remain unchanged for a long time, and thus dust and other impurities will enter their interiors. Therefore, lubrication is required. When the mounting piece 16 moves inward, the mounting piece 16 can pull the slider 11 to move inward, so that the slider 11 no longer blocks the connection between the oil groove 10 and the sliding groove 13, and the communication groove 12 on the slider 11 can communicate with the sliding groove 13. Thus, the lubricating oil in the oil groove 10 can enter the interior of the sliding groove 13 through the communication groove 12, and then enter the interior of the limiting groove 9 through the sliding groove 13, so as to lubricate the sliding part between the third support rod 7 and the limiting block 8, and make the movement of the third support rod 7 more convenient. On the contrary, when the mounting piece 16 moves outward, the mounting piece 16 can pull the slider 11 to move outward, so that the communication groove 12 no longer communicates with the oil groove 10, and the slider 11 can block the connection between the oil groove 10 and the sliding groove 13, so that the lubricating oil no longer flows out. When lubricating oil needs to be added, by fitting the top end of the third support rod 7 to the upper side of the inner wall of the placement groove 6, the oil injection pipe on the second support rod 5 can be inserted into the interior of the sealing plug 20, and then the interior of the oil groove 10 can be filled with lubricating oil.

[0031] In actual use, the second support rod 5 is rotated out from the inside of the first support rod 2. At this time, the top end of the third support rod 7 is in contact with the upper side of the inner wall of the placement groove 6, so that the oil injection pipe on the second support rod 5 can be inserted into the inside of the sealing plug 20, and then lubricating oil is added to the inside of the oil tank 10. Subsequently, by pushing the two push rods 17 towards the adjacent side, the push rods 17 can push the mounting piece 16 towards the inner end. And when the arc of the push rod 17 enters the inside of the clamping groove 18, by pulling the third support rod 7 downward, the third support rod 7 can drive the push rod 17 to move downward, so that the arc of the push rod 17 can slide on the inner wall of the second support rod 5, and the mounting piece 16 can pull the slider 11 to move inward, so that the slider 11 no longer blocks the communication between the oil tank 10 and the chute 13. Then, the communication groove 12 on the slider 11 can communicate with the chute 13, so that the lubricating oil inside the oil tank 10 can enter the inside of the chute 13 through the communication groove 12, and then enter the inside of the limiting groove 9 through the chute 13, so that the third support rod 7 and the limiting block 8 can slide conveniently. When the push rod 17 is in a horizontal position with the next clamping groove 18, the elastic member 15 can perform a reset movement, so that the elastic member 15 can push the mounting piece 16 to move outward, so that the mounting piece 16 can push the push rod 17 to engage with the clamping groove 18, so as to limit the third support rod 7. The mounting piece 16 can pull the slider 11 to move outward, so that the communication groove 12 no longer communicates with the oil tank 10, and the slider 11 can block the communication between the oil tank 10 and the chute 13, so that the lubricating oil no longer flows out. Repeat the above operations until the third support rod 7 extends out of the placement groove 6 by the required distance. Then, the pin 19 is passed through the third support rod 7 and inserted into the inside of the base 1, so as to fix the positions of the third support rod 7 and the second support rod 5, and then support the first support rod 2, so that the first support rod 2, the second support rod 5 and the third support rod 7 can jointly support the base 1, so as to additionally increase the supporting force for the photovoltaic module, so that the first support rod 2 is not easily deformed. Then, not only the supporting stability is higher, but also the inclination angle adjustment is more convenient, so that the photoelectric conversion efficiency is not affected, and the use economy is better.
