Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic bracket device. Background Art

[0002] The current mainstream balcony photovoltaic mounting solution mainly uses a tripod to support the photovoltaic panels. The tripod is composed of an inclined beam, a bottom beam, and a diagonal brace. The tripod is hung on the outside of the balcony railing via a hook connected to the tripod. The bottom of the tripod is connected to the vertical balcony railing with a clamping plate.

[0003] The technical route of existing balcony photovoltaic bracket products is relatively mature, and most products on the market are similar in form, but they basically have the disadvantage of being difficult to package: the existing balcony photovoltaic brackets have many rods and cannot be folded for storage, and the connectors and splints have different shapes. When packaging, the space utilization rate is poor, which increases the packaging and transportation costs. Utility Model Content

[0004] In view of this, the present invention provides a photovoltaic support device to solve the problem of packaging and transportation costs.

[0005] In a first aspect, the present invention provides a photovoltaic support device, comprising:

[0009] In an optional embodiment, the inclined beam is provided with at least two adjustment holes; the inclined beam is connected to the diagonal brace through the adjustment holes. By adding adjustment holes to the inclined beam, when the inclined beam and the diagonal brace are connected through different adjustment holes, the angle between the inclined beam and the diagonal brace is different, thereby adjusting the tilt angle of the photovoltaic panel to meet different needs.

The first clamping hook and the second clamping hook are movably connected through the first adjustment hole, so that the first accommodating space between the first clamping hook and the second clamping hook can be reasonably increased or decreased as needed, thereby improving the adaptability of the overall structure and being able to match lower railings of different specifications.

[0012] In an optional embodiment, the method further includes:

[0013] A second clamping assembly is disposed between the oblique beam and the upper railing; the first end of the second clamping assembly is adapted to be fixedly connected to the first end of the oblique beam; the second end of the second clamping assembly is bent to form a hook portion, and a second accommodating space is formed between the inner walls of the hook portion, and the second accommodating space is adapted to accommodate the upper railing. The oblique beam is connected to the upper railing via the second clamping assembly, and the second accommodating space is adapted to accommodate the upper railing, thereby increasing the stability of the connection between the oblique beam and the upper railing and the overall stability of the structure.

[0014] In an optional embodiment, the second clamping assembly is provided with a second adjustment hole; the second adjustment hole is in the shape of a bar; and the second clamping assembly is connected to the inclined beam via the second adjustment hole. The second clamping assembly is connected to the inclined beam via the second adjustment hole, thereby compensating for errors that may occur during the installation of the inclined beam and increasing the error tolerance.

[0015] In an optional embodiment, the method further includes:

[0016] There is at least one crossbar, which is arranged between adjacent diagonal beams. The crossbar has a fixed length and can act as a fixed length. During the installation process, there is no need for measurement and positioning, thereby simplifying the installation process and increasing convenience.

[0017] In an optional embodiment, the method further includes:

[0018] An angle bracket is provided at the end of the crossbar; the crossbar is fixedly connected to the oblique beam via the angle bracket.

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0031] Most products on the market are similar, but they all share the following shortcomings: 1. High cost: Mainstream aluminum alloy balcony brackets use a lot of materials and include hooks, plywood, connectors, fasteners, and other auxiliary materials, resulting in high material and installation costs. Stainless steel profiles are even more expensive than aluminum alloy brackets, and galvanized aluminum-magnesium profiles have poor market acceptance due to poor quality control. Poor aesthetics: Existing balcony brackets use too many profiles, resulting in a bloated structure and a lack of simplicity and clarity. The plywood connection protrudes inward from the balcony railing, affecting the overall aesthetics. The profiles or pressing blocks are exposed, making them awkward.

[0032] Difficult installation: Balcony photovoltaic systems are positioned as small household micro power stations and are usually installed by users themselves. Existing bracket products have many connection positions and a low degree of pre-installation, so the installation process is often time-consuming and labor-intensive.

[0033] Difficult to pack: The existing balcony photovoltaic bracket has many rods and cannot be folded for storage. The connectors and splints are of different shapes. When packing, the space utilization rate is poor, which increases the packaging and transportation costs.

[0034] Poor stability: Some balcony brackets omit the inclined beam 1 and bottom beam design, and adopt the inclined support 2 plus four-point fixed constraint form, which makes the overall structural strength of the bracket insufficient. In summary, a new balcony photovoltaic bracket installation solution is urgently needed.

[0035] like Figure 1 and Figure 2 As shown, according to the embodiment of the present invention, on the one hand, the present invention provides a photovoltaic bracket device, comprising: an oblique beam 1 and an oblique brace 2; wherein the oblique beam 1 has at least two; a mounting groove is formed inside the oblique beam 1; the first end of the oblique beam 1 is suitable for being fixedly connected to the upper railing; a mounting hole is opened on the oblique beam 1, and the oblique beam 1 is suitable for fixing and installing a photovoltaic panel 8 through the mounting hole; wherein the number of the oblique braces 2 corresponds to the number of the oblique beams 1; the first end of the oblique brace 2 is suitable for being hinged to the oblique beam 1; the second end of the oblique brace 2 is suitable for being fixedly connected to the lower railing; the oblique brace 2 includes a storage state and a support state; as shown in FIG. Figure 3 As shown, when the diagonal brace 2 is in the storage state, the diagonal brace 2 is entirely located in the installation groove; when the diagonal brace 2 is in the supporting state, the diagonal brace 2 is partially located in the installation groove.

[0036] Compared with the traditional solution, this solution uses fewer types and quantities of profiles through the coordinated installation of the diagonal brace 2 and the diagonal beam 1, which reduces costs. In addition, the diagonal brace 2 is in a stored state during transportation, and when in the stored state, the diagonal brace 2 is completely located in the installation groove, which greatly reduces the overall occupied space, thereby reducing packaging and transportation costs.

[0037] It should be noted that, in this embodiment, the upper railing and the lower railing are both common railings for balconies. Specifically, the lower railing refers to the horizontal railing close to the ground, and the upper railing refers to the horizontal railing away from the ground.

[0038] It should be noted that, in this embodiment, there are two inclined beams 1 , and the number of inclined beams 1 can be determined according to the number of photovoltaic panels 8 to be installed and the actual length of the railing.

[0039] It should be noted that the first end of the diagonal brace 2 is hinged to the diagonal beam 1 through bolts. The bolts are loosened so that the diagonal beam 1 and the diagonal brace 2 can be hinged at any angle. After the position is determined, the bolts are tightened to achieve a fixed connection.

[0040] In one embodiment, the inclined beam 1 is provided with at least two adjustment holes 101; the inclined beam 1 is connected to the diagonal brace 2 through the adjustment holes 101. By adding adjustment holes 101 to the inclined beam 1, when the inclined beam 1 and the diagonal brace 2 are connected through different adjustment holes 101, the angle between the inclined beam 1 and the diagonal brace 2 is different, thereby achieving the adjustment of the tilt angle of the photovoltaic panel 8 to meet different needs.

[0041] It should be noted that, in this embodiment, both the oblique beam 1 and the oblique brace 2 are made of aluminum alloy profiles with a C-shaped opening. In order to ensure that the oblique brace 2 can enter the installation groove, the size of the oblique brace 2 is slightly smaller than that of the oblique beam 1.

[0042] It should be noted that the inclined beam 1, the inclined brace 2 and the handrail form a triangle, which can ensure the stability of the overall structure while reducing the amount of material used.

[0043] It should be noted that when the diagonal brace 2 is in the supporting state, only part of the end portion of the diagonal brace 2 is located in the installation groove.

[0044] It should be noted that in this embodiment, the number of adjustment holes 101 is four, and the number of adjustment holes 101 can be reasonably increased or decreased according to needs, and the spacing between the adjustment holes 101 can also be inspected and adjusted as needed. Since the length of the diagonal brace 2 and the distance between the upper and lower railings are fixed, the triangle formed between the diagonal brace 2, the diagonal beam 1 and the railing will change with the different connection positions of the diagonal brace 2 and the diagonal beam 1.

[0045] like Figure 4As shown, in one embodiment, it also includes: a first clamping assembly 3, which is arranged between the diagonal support 2 and the lower railing; the first clamping assembly 3 includes a first clamping hook 301 and a second clamping hook 302; the first end of the first clamping hook 301 is suitable for being fixedly connected to the second end of the diagonal beam 1; the first clamping hook 301 is provided with a first adjustment hole 303; the first adjustment hole 303 is bar-shaped; the second clamping hook 302 is fixedly connected to the first clamping hook 301 through the first adjustment hole 303; a first accommodating space is formed between the first clamping hook 301 and the second clamping hook 302; the first accommodating space is suitable for accommodating the lower railing. The first clamping hook 301 and the second clamping hook 302 are movably connected through the first adjustment hole 303, so that the first accommodating space between the first clamping hook 301 and the second clamping hook 302 can be reasonably increased or decreased as needed, thereby improving the adaptability of the overall structure and being able to match lower railings of different specifications.

[0046] When the first clamping hook 301 and the second clamping hook 302 are in the L-shaped plate, the first clamping hook 301 and the second clamping hook 302 are connected by bolts, wherein a first adjustment hole 303 is provided on the first clamping hook 301, and a corresponding bolt hole is provided on the second clamping hook 302. The bolts pass through the first adjustment hole 303 on the first clamping hook 301 and the screw holes on the second clamping hook 302 respectively. When the position of the first accommodating space needs to be adjusted, the bolts are loosened, and then the positions of the first clamping hook 301 and the second clamping hook 302 are manually adjusted. Specifically, the short sides of the first clamping hook 301 and the second clamping hook 302 are brought closer to each other to reduce the size of the first accommodating space, and the short board sides of the first clamping hook 301 and the second clamping hook 302 are moved away from each other to expand the size of the first accommodating space. In this embodiment, it is best to make the size of the first accommodating space the same as the size of the lower railing. After the size of the first accommodating space is adjusted, the first clamping hook 301 and the second clamping hook 302 are fixedly connected by tightening the bolts to ensure the stability of the overall structure.

[0047] It should be noted that a bolt hole is provided near the first end of the first clamping hook 301 , and the first end of the first clamping hook 301 is fixedly connected to the second end of the oblique beam 1 through the bolt hole.

[0048] It should be noted that a first locking hole is also provided on the first clamping hook 301 and the second clamping hook 302, and the first locking hole is also long and strip-shaped. After adjusting the positions of the first clamping hook 301 and the second clamping hook 302, the lower railing is placed at the innermost part of the first accommodating space, and then the bolt is passed through the two first locking holes, and the bolt is abutted against the lower railing. The lower railing is locked in the first accommodating space through the cooperation of the bolt and the first locking hole, ensuring that the lower railing will not detach from the first accommodating space during use, and ensuring that the first clamping assembly 3 is locked with the lower railing to ensure the stability of the overall structure.

[0049] like Figure 5 As shown, in one embodiment, it also includes:

[0050] A second clamping assembly 4 is disposed between the oblique beam 1 and the upper railing. The first end of the second clamping assembly 4 is adapted to be fixedly connected to the first end of the oblique beam 1. The second end of the second clamping assembly 4 is bent to form a hook portion 401. The inner wall of the hook portion 401 defines a second accommodating space suitable for accommodating the upper railing. The oblique beam 1 is connected to the upper railing via the second clamping assembly 4, with the second accommodating space suitable for accommodating the upper railing, thereby increasing the stability of the connection between the oblique beam 1 and the upper railing and the overall structure.

[0051] It should be noted that the specific cross-section of the hook portion 401 of the second clamping assembly 4 is "U"-shaped, and a second accommodating space is formed between its two inner walls. It should be noted that second locking holes are also provided on both sides of the second clamping assembly 4. After the upper railing is placed in the second accommodating space, bolts are passed through the two second locking holes, and the bolts are in contact with the upper railing, so that the upper railing is locked inside the second accommodating space, and it is ensured that the upper railing will not detach from the second accommodating space, thereby ensuring the stability of the overall structure.

[0052] In one embodiment, the second clamping assembly 4 is provided with a second adjustment hole 402; the second adjustment hole 402 is in the shape of a bar; the second clamping assembly 4 is connected to the inclined beam 1 via the second adjustment hole 402. The second clamping assembly 4 is connected to the inclined beam 1 via the second adjustment hole 402, which can compensate for errors in the installation process of the inclined beam 1 and increase the error tolerance.

[0053] It should be noted that by opening a second adjustment hole 402 on the second clamping component 4, the inclined beam 1 has the function of elongation and shortening in disguise, thereby compensating for the error generated during the installation of the inclined beam 1. Specifically, by passing the bolt through the bolt hole on the inclined beam 1 and the second adjustment hole 402 on the second clamping component 4, when it is necessary to adjust the length of the inclined beam 1 and the second clamping component 4, the bolt is loosened, and the relative position of the second clamping component 4 and the inclined beam 1 is manually adjusted, and then the bolt is tightened to fix it.

[0054] It should be noted that the first clamping component 3 and the second clamping component 4 are made of stainless steel.

[0055] In one embodiment, it further includes:

[0056] There is at least one crossbar 5; the crossbar 5 is arranged between adjacent inclined beams 1. The length of the crossbar 5 is fixed, and the crossbar 5 can act as a fixed length. There is no need to measure and position during the installation process, thereby simplifying the installation process and increasing convenience.

[0057] It should be noted that a number of through holes are opened in the middle of the crossbar 5 for fixing the micro inverter. The micro inverter is suitable for connecting with the photovoltaic panel 8 and is used for converting between direct current and alternating current.

[0058] like Figure 6 As shown, in one embodiment, it also includes:

[0059] An angle bracket 6 is provided at the end of the crossbar 5; the crossbar 5 is fixedly connected to the oblique beam 1 via the angle bracket 6. The crossbar 5 is fixedly connected to the oblique beam 1 via the angle bracket 6, further increasing the stability of the connection between the crossbar 5 and the oblique beam 1.

[0060] It should be noted that bolt holes are provided at the ends of crossbar 5, and bolt holes are also provided at positions corresponding to crossbar 5 on diagonal beam 1. Angle bracket 6 is specifically an L-shaped plate, with one side of angle bracket 6 fixedly connected to crossbar 5 by bolts, and the other side of angle bracket 6 fixedly connected to diagonal beam 1. Crossbar 5 is fixedly connected to diagonal beam 1 via angle bracket 6. This method reduces exposed and protruding parts, making the overall structure more concise and clear.

[0061] like Figure 7 As shown, in one embodiment, the diagonal beam 1 and the diagonal brace 2 are both C-shaped open alloy profiles; the diagonal beam 1 and the diagonal brace 2 are fixedly connected by bolts; bolt sleeves 7 are mounted outside the bolts, and the ends of the bolt sleeves 7 abut the inner wall of the diagonal brace 2. By adding the bolt sleeves 7 and abutting the inner side of the diagonal brace 2, the local strength of the node can be increased, bending and other problems can be avoided, and the overall life can be increased.

[0062] It should be noted that all components in this solution are sprayed black, which can effectively hide the corner code 6 and the bolt connection structure in appearance, making the overall structure simpler.

[0063] It should be noted that all aluminum alloy profiles are black anodized. The remaining parts are also painted black.

[0064] It should be noted that all bolts are made of stainless steel flange bolts and flange nuts, omitting flat washers and spring washers, which reduces the difficulty of installation and has an anti-loosening effect.

[0065] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
