Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic panel installation, and more specifically, relates to a telescopic support for photovoltaic panels. Background Art

[0002] With the progress of photovoltaic power generation technology, the application scope of photovoltaic power generation is becoming more and more extensive, and the development of household photovoltaic power generation is rapid. However, the current photovoltaic power generation has certain limitations and can only be installed on the sloping roofs of villas or the flat roofs of bungalows. For high-rise buildings, its installation utilization rate is relatively low. At present, there are also photovoltaic panel supports installed on balconies on the market, and the photovoltaic panel supports can adjust the angle of the photovoltaic panels to ensure the photoelectric conversion efficiency of the photovoltaic panels. However, the existing photovoltaic panel supports installed on balconies are difficult to transport due to their large volume. Moreover, considering that the angle of the support needs to be changed when installed on the balcony so that the photovoltaic panels can better contact sunlight to ensure its effect, this results in cumbersome structural components of the photovoltaic panel support and high manufacturing costs.

[0003] Corresponding improvements have also been made to the above problems. For example, Chinese Patent Application No. CN202320382873.8, with a publication date of August 22, 2023, discloses a photovoltaic panel adjustment support, including a counterweight seat and a driving bevel gear. A motor is installed inside the counterweight seat, the output end of the motor is connected to a transmission shaft, and the driving bevel gear is connected to one end of the transmission shaft. By using the combination of the set motor, driving bevel gear, driven bevel gear, threaded rod, and telescopic push rod, the inclination angle of the entire top frame can be adjusted according to the actual lighting conditions. When the motor works, the driving bevel gear connected to its output end rotates accordingly. Since the driving bevel gear and the driven bevel gear are meshed, the synchronous rotation of the threaded rod can be achieved through the linkage of multiple driven bevel gears. Since the threaded rod and the first threaded sleeve are in threaded connection, the first threaded sleeve will move horizontally as the threaded rod rotates, thereby pushing the telescopic push rod, and then using the telescopic push rod to adjust the inclination angle of the entire top frame. The disadvantage of this patent is that the overall structure for realizing adjustment is complex and the cost is high.

[0004] For another example, Chinese Patent Application No. CN202110553382.0, with a publication date of July 30, 2021, discloses a photovoltaic panel power generation bracket, which includes: a bracket inclined beam, a first vertical rod, a second vertical rod, and a telescopic connecting rod; one end of the first vertical rod is fixedly installed on the ground to be installed, and the other end of the first vertical rod is connected to the bracket inclined beam through a rotating shaft; one end of the second vertical rod is fixedly installed on the ground to be installed, and the other end of the second vertical rod is fixedly connected to one end of the telescopic connecting rod; the other end of the telescopic connecting rod is fixedly connected to the bracket inclined beam through; the bracket inclined beam is used to fix the photovoltaic panel; by adjusting the length of the telescopic connecting rod, the inclination angle of the photovoltaic panel with respect to the ground is adjusted. The disadvantage of this patent is that the fixing strength of the photovoltaic panel is weak, and the photovoltaic panel is likely to fall off in bad weather such as strong winds.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] (1) The present utility model fixes the photovoltaic panel through a plurality of support components, and each support component can be independently installed and transported, greatly reducing the transportation volume, thereby reducing the transportation cost; at the same time, the support component includes two telescopic rods, and the setting of the telescopic rods enables the angle of the photovoltaic panel on the telescopic bracket to be adjustable, so as to better adapt to the sunlight in different directions and ensure the heat absorption effect; and the photovoltaic panel is fixed in different directions through the pressing block on the support component, increasing the connection strength of the photovoltaic panel, so that the photovoltaic panel can still be stably placed on the telescopic bracket in the face of bad weather such as strong winds; the whole photovoltaic panel telescopic bracket has a simple structure and a low manufacturing cost; each component can be disassembled, greatly reducing the overall volume, thereby facilitating transportation and reducing the transportation cost; at the same time, it can ensure strong stability in connection with the photovoltaic panel;

[0020] (2) In this utility model, the ends of the first telescopic rod and the second telescopic rod are roll - pressed to form the first thread, and the connecting pipe is roll - pressed to form the second thread. The threaded connection between the two telescopic rods and the connecting pipe does not rely on the one - way thread of two objects in the traditional way. The use of roll - formed threads eliminates the need to thicken the pipe walls of the telescopic rods and the connecting pipe to form threads, reducing costs and making the operation more convenient. At the same time, the ends of the two telescopic rods are bent, which is convenient for installation with other components and improves the installation efficiency.

[0021] (3) The connecting piece of this utility model is arranged in two sections, so that the connection with the pressing block and the telescopic rod does not interfere with each other, ensuring the stability of the connection. And the connection between the two sections adopts an arc transition. On the one hand, it avoids accidental scratches on workers during the installation process. On the other hand, it avoids stress concentration and easy fracture at the connection. And a clamping baffle is also arranged on the connecting piece, and the side wall of the photovoltaic panel is clamped through the clamping baffle, further strengthening the stability of the connection with the photovoltaic panel.

[0022] (4) The pressing block in this utility model adopts a four - section stepped shape. Compared with directly fixing the surface of the connecting piece, it raises the connection height between the fastener and the connecting piece, and then reduces the distance between the force - bearing point of the fastener and the force - bearing points between the pressing block and the photovoltaic panel, increasing the force required for the photovoltaic panel to rotate. As a result, the wind resistance of the photovoltaic panel is enhanced, making it difficult for the photovoltaic panel to flip on the connecting piece and ensuring stability.

[0023] (5) The setting of the hook in this utility model further broadens the application scenarios of the telescopic bracket, enabling it to be hung on the balcony for use. And a number of equally - spaced clamping cavities on the hook can fix photovoltaic panels of different sizes, increasing the applicability of the entire telescopic bracket and thus reducing costs.

[0029] The present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0030] Embodiment 1

[0031] As Figure 1 and Figure 2 shown, a telescopic bracket for a photovoltaic panel includes a plurality of support components for fixing the photovoltaic panel 7; generally speaking, the number of its support components is two, and the two sides of the photovoltaic panel 7 are fixed by the two support components, which not only ensures stability but also avoids the problem of increased cost caused by too many support components. For a single support component, the support component includes a first telescopic rod 1 and a second telescopic rod 2. One ends of the first telescopic rod 1 and the second telescopic rod 2 are respectively hinged with a connector 6, and the connector 6 is connected to the photovoltaic panel 7 through a pressure block 5, and the pressure block 5 is used to fix the photovoltaic panel; the other ends of the first telescopic rod 1 and the second telescopic rod 2 are threadedly connected through a connecting pipe 3.

[0032] Specifically, that is, the two telescopic rods are arranged at an angle, and the two telescopic rods are connected to the photovoltaic panel 7 at different positions (generally for the purpose of installation and fixing effect, the first telescopic rod 1 is connected to the top of the photovoltaic panel 7, and the second telescopic rod 2 is connected to the bottom of the photovoltaic panel 7), so that a triangular structure is formed between the two telescopic rods and the photovoltaic panel 7. A triangle has high stability, so the connection of the two telescopic rods to the photovoltaic panel 7 ensures the connection strength and stability of the photovoltaic panel 7. And the pressure block 5 can further fix the photovoltaic panel 7, thereby improving the stability of the photovoltaic panel 7. The setting of the connecting pipe 3 makes the connection between the two telescopic rods smoother.

[0033] The present utility model fixes the photovoltaic panel 7 through a plurality of support components, and each support component can be independently installed and transported, greatly reducing the transportation volume and thus reducing the transportation cost. At the same time, the support component includes two telescopic rods. The setting of the telescopic rods enables the angle of the photovoltaic panel 7 on the telescopic bracket to be adjustable, so as to better adapt to the sunlight in different directions and ensure the heat absorption effect. And the photovoltaic panel 7 is fixed in different directions through the pressing block 5 on the support component, increasing the connection strength of the photovoltaic panel 7, so that the photovoltaic panel 7 can still be stably placed on the telescopic bracket in the face of bad weather such as strong winds. The entire telescopic bracket for the photovoltaic panel has a simple structure and a low manufacturing cost. Each component can be disassembled, greatly reducing the overall volume, thus facilitating transportation and reducing the transportation cost. At the same time, it can ensure strong stability in connection with the photovoltaic panel 7.

[0034] In one embodiment, generally considering from the aspect of strength, both the first telescopic rod 1 and the second telescopic rod 2 are made of stainless steel. If the connection between the two telescopic rods adopts a conventional one-way thread connection (that is, threads are provided on the inner surface of the telescopic rod and matching threads are provided on the outer surface of the connecting pipe 3), it will inevitably increase the wall thickness of the two telescopic rods and the connecting pipe 3, with insufficient connection strength and increased cost. Therefore, the present application adopts the following method: the other end of the first telescopic rod 1 and the other end of the second telescopic rod 2 are respectively formed with a first thread by rolling, and both ends of the connecting pipe 3 are respectively formed with a second thread matching the first thread by rolling; specifically, the ends of the two telescopic rods can be reduced, and then the first thread is formed both inside and outside the reduced ends of the telescopic rods by rolling; the two ends of the connecting pipe 3 are enlarged, and then the second thread is formed at both ends of the connecting pipe 3 by rolling. The sizes of the reduction and enlargement here match each other. The method of forming threads by rolling is suitable for the processing of high-strength and high-hardness threads, with high efficiency, high connection strength and low cost.

[0035] In one embodiment, the end of the first telescopic rod 1 connected to the connecting piece 6 is arranged in a curved shape; the end of the second telescopic rod 2 connected to the connecting piece 6 is arranged in a curved shape. That is, the end of the telescopic rod in contact with the photovoltaic panel 7 is set in a curved shape. The curved shape is more convenient for connection with the connecting piece 6, facilitating installation, and is not likely to interfere with surrounding components during the installation process, with a large operating space. It should be noted that the curved shape here can be achieved by connecting a bent pipe at the end of the telescopic rod or directly bending the end of the telescopic rod, and the bending direction is downward.

[0036] In one embodiment, as Figure 3As shown, the connecting member 6 includes a first connecting body 61 and a second connecting body 62 which are vertically arranged. The first connecting body 61 is in a vertical state, and an installation through-hole is formed on the first connecting body 61. The pressing block 5 is arranged in the installation through-hole through a fastener (a fastening bolt or a fastening screw); the second connecting body 62 is in a horizontal state, and a connecting through-hole is formed on the second connecting body 62. The end of the telescopic rod is hinged to the connecting through-hole through a fastener (a fastening bolt or a fastening screw). The first connecting body 61 is used for connecting with the pressing block 5, and the second connecting body 62 is used for connecting with the telescopic rod, without interfering with each other, ensuring the stability of their connection.

[0037] More preferably, the connection between the first connecting body 61 and the second connecting body 62 is in an arc transition; on the one hand, it can avoid accidental scratches on workers during the installation process, and on the other hand, it can avoid stress concentration and easy fracture at the connection. And a clamping baffle 63 is arranged on the first connecting body 61. A clamping space is formed between the clamping baffle 63 and the first connecting body 61, and the clamping space is used for clamping the photovoltaic panel 7. Specifically, the clamping baffle 63 is arranged at the end of the first connecting body 61 and is arranged upward towards the top of the photovoltaic panel 7. Since the photovoltaic panel 7 is usually rectangular, but each side has a thickness to form a side wall, the setting of the clamping baffle 63 clamps the side wall of the photovoltaic panel 7, further strengthening the stability of the connection with the photovoltaic panel 7.

[0038] In one embodiment, as Figure 4 shown, the pressing block 5 is in a stepped shape, which includes a pressing part 51, a contact part 52, a connecting part 56 and an adjusting part 53 connected in sequence. The pressing part 51 and the contact part 52 are in contact with different surfaces of the photovoltaic panel 7 respectively. The connecting part 56 is arranged parallel to the installation through-hole, and the connecting part 56 is fixed to the installation through-hole. The adjusting part 53 is arranged perpendicular to the installation through-hole. The pressing block 5 adopts a four-stage stepped shape. Compared with directly fixing the surface of the connecting member 6, it raises the connection height between the fastener and the connecting member 6, and then reduces the distance between the force application point of the fastener and the force application points between the pressing block 5 and the photovoltaic panel 7, increases the force required for the photovoltaic panel 7 to rotate, and then enhances the wind resistance of the photovoltaic panel 7, making the photovoltaic panel 7 not easy to flip on the connecting member, ensuring the stability.

[0039] In one embodiment, it further includes a hook 4. The hook 4 includes a vertical portion connected to the photovoltaic panel 7. The end of the vertical portion is provided with a bent portion that bends downward along the end of the vertical portion. A clamping space is formed between the vertical portion and the bent portion, and the clamping space is used to clamp an external object. Both the vertical portion and the bent portion can be implemented by plate-like components. The setting of the hook 4 further broadens the usage scenarios of the telescopic bracket, enabling it to be not only placed on the ground for use but also suspended for use, such as being suspended on a balcony. The vertical portion of the hook 4 is fixedly connected to the photovoltaic panel 7, and the railing on the balcony is fixed in the clamping space to complete the suspended use.

[0040] Preferably, a plurality of equally spaced engaging cavities are provided on the vertical portion of the hook 4. The engaging cavities are used to engage with the photovoltaic panel 7, which can achieve fixation with photovoltaic panels 7 of different sizes and fixation with external objects at different heights, increasing the applicability of the entire telescopic bracket and thus reducing costs. The engaging cavities can be formed in the following manner: that is, a plurality of through holes are opened on the vertical portion of the hook 4, and a vertically upward limiting plate parallel to the through holes is provided on one side of each through hole facing the photovoltaic panel 7. The limiting plate is connected to the vertical portion where the through hole is located, so that a clamping cavity is formed between the limiting plate and the through hole, and mounting holes are correspondingly provided on the limiting plate. The hook 4 and the photovoltaic panel 7 are installed and fixed by passing fasteners through the through holes and the mounting holes.

[0041] The examples of the present invention only describe the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various deformations and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the protection scope of the present invention.
