Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic bracket device and an installation method. Background Art

[0002] The existing mainstream balcony photovoltaic support solution is mainly to support the photovoltaic modules with a tripod, which is composed of an inclined beam, a bottom beam, and an inclined brace. The tripod is hung on the outside of the balcony railing through a hook connected to the tripod, and a clamp is used at the bottom to connect and fix the bottom beam of the tripod to the vertical balcony railing.

[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 shapes of connectors and splints are different. When packaging, the space utilization rate is poor, which increases the packaging and transportation costs. Summary of the invention

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

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

[0008] Beneficial effect: Compared with the traditional solution, this solution uses the coordinated installation of diagonal braces and diagonal beams, which reduces the types and quantity of profiles and reduces costs. The diagonal braces are in a stored state during transportation, and are completely located in the installation groove when in the stored state, greatly reducing the overall occupied space, thereby reducing packaging and transportation costs.

[0009] In an optional embodiment, at least two adjustment holes are provided on the inclined beam; the inclined beam is connected to the inclined brace through the adjustment holes. By adding adjustment holes on the inclined beam, when the inclined beam and the inclined brace are connected through different adjustment holes, the angle between the inclined beam and the inclined brace is different, so that the inclination angle of the photovoltaic panel can be adjusted to meet different needs.

[0010] In an optional implementation, it also includes:

[0011] The first clamping assembly is arranged between the diagonal brace and the lower railing; the first clamping assembly includes a first clamping hook and a second clamping hook; the first end of the first clamping hook is suitable for being fixedly connected to the second end of the diagonal beam; the first clamping hook is provided with a first adjustment hole; the first adjustment hole is in a strip shape; the second clamping hook is fixedly connected to the first clamping hook through the first adjustment hole; a first accommodation space is formed between the first clamping hook and the second clamping hook; the first accommodation space is suitable for accommodating the lower railing. The first clamping hook and the second clamping hook are movably connected through the first adjustment hole, so that the first accommodation 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 implementation, it also includes:

[0013] The second clamping assembly is arranged 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 and arranged 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 through the second clamping assembly, wherein 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 increasing the stability of the overall structure.

[0014] In an optional embodiment, a second adjustment hole is provided on the second clamping assembly; the second adjustment hole is in a strip shape; the second clamping assembly is connected to the inclined beam through the second adjustment hole. The second clamping assembly is connected to the inclined beam through the second adjustment hole, which can compensate for errors generated during the installation of the inclined beam and increase the error tolerance.

[0015] In an optional implementation, it also includes:

[0016] There is at least one crossbar; the crossbar is arranged between adjacent inclined beams. The length of the crossbar is fixed, and the crossbar can act as a sizing effect.

By adding bolt sleeves, the bolt sleeves abut against the inner side of the oblique brace, the local strength of the node can be increased, bending and the like can be avoided, and the overall life can be increased.

[0020] In a second aspect, the present invention further provides a method for installing a photovoltaic bracket, comprising the photovoltaic bracket device described in any one of the above, and further comprising the following steps:

[0021] The diagonal beam and diagonal brace are pre-processed in the factory, and the diagonal brace is in a storage state during transportation; the diagonal beam and diagonal brace are opened to a suitable angle on site, so that the diagonal brace is in a supporting state; the first end of the diagonal beam is fixed to the upper railing; the second end of the diagonal brace is fixed to the lower railing. Compared with the traditional solution, this solution uses the diagonal brace and the diagonal beam for installation. The type and quantity of profiles will be less, which reduces the cost. The diagonal brace is in a storage state during transportation, and the diagonal brace is completely located in the installation groove when it is in the storage state, which greatly reduces the overall occupied space, thereby reducing the packaging and transportation costs.

[0022] In an optional implementation, it also includes:

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0039] Most of the products on the market are similar, but they basically have the following disadvantages: 1. High cost: The mainstream aluminum alloy balcony bracket uses more materials and includes hooks, splints, connectors, fasteners and other auxiliary materials, and the material cost and installation cost are high; the price of stainless steel profiles is even higher than that of aluminum alloy brackets, and the galvanized aluminum-magnesium material has poor market acceptance due to poor quality control. Poor aesthetics: The existing balcony bracket uses a lot of profiles, the structure is bloated, and the appearance is not simple and clear; the splint connection protrudes inward from the balcony railing, affecting the overall appearance; the profile or block is exposed, which is more abrupt.

[0040] Difficult installation: Balcony photovoltaic systems are positioned as small household micro power stations and are usually installed by users themselves. The existing bracket products have many connection positions and a low degree of pre-installation, so the installation process is often time-consuming and laborious.

[0041] 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.

[0042] Poor stability: Some balcony brackets omit the inclined beam 1 and the bottom beam design, and adopt the constraint form of inclined support 2 plus four-point fixation, and the overall structural strength of the bracket is insufficient. In summary, a new balcony photovoltaic bracket installation scheme is urgently needed.

[0043] like Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, on the one hand, the present invention provides a photovoltaic bracket device, comprising: an inclined beam 1 and an inclined brace 2; wherein the inclined beam 1 has at least two; a mounting groove is formed inside the inclined beam 1; the first end of the inclined beam 1 is suitable for being fixedly connected to the upper railing; a mounting hole is provided on the inclined beam 1, and the inclined beam 1 is suitable for fixing and installing a photovoltaic panel 8 through the mounting hole; wherein the number of the inclined braces 2 corresponds to the number of the inclined beams 1; the first end of the inclined brace 2 is suitable for being hinged to the inclined beam 1; the second end of the inclined brace 2 is suitable for being fixedly connected to the lower railing; the inclined 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 completely 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] It should be noted that the first end of the diagonal brace 2 is hinged to the diagonal beam 1 by 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.

[0048] In one embodiment, at least two adjustment holes 101 are provided on the inclined beam 1; the inclined beam 1 is connected to the inclined brace 2 through the adjustment holes 101. By adding the adjustment holes 101 on the inclined beam 1, when the inclined beam 1 is connected to the inclined brace 2 through different adjustment holes 101, the angle between the inclined beam 1 and the inclined brace 2 is different, so that the inclination angle of the photovoltaic panel 8 can be adjusted to meet different needs.

[0049] It should be noted that, in this embodiment, both the inclined beam 1 and the inclined brace 2 are made of aluminum alloy profiles with C-shaped openings. In order to ensure that the inclined brace 2 can enter the installation groove, the size of the inclined brace 2 is slightly smaller than that of the inclined beam 1.

[0050] 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.

[0051] It should be noted that when the diagonal brace 2 is in the supporting state, only part of the end of the diagonal brace 2 is located in the installation groove.

[0052] It should be noted that in the present embodiment, the number of adjustment holes 101 is four, and the number of adjustment holes 101 can be reasonably increased or decreased according to demand, 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 by 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.

[0053] like Figure 4 As 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 in a strip shape; the second clamping hook 302 is fixedly connected to the first clamping hook 301 through the first adjustment hole 303; a first accommodation space is formed between the first clamping hook 301 and the second clamping hook 302; the first accommodation 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 accommodation 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.

[0054] It should be noted that the first clamping hook 301 and the second clamping hook 302 are both L-shaped plates; 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, and the bolts pass through the first adjustment hole 303 on the first clamping hook 301 and the screw hole on the second clamping hook 302 respectively. When it is necessary to adjust the position of the first accommodating space, 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.

[0055] 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 inclined beam 1 through the bolt hole.

[0056] It should be noted that a first locking hole is also provided on the first clamp hook 301 and the second clamp hook 302, and the first locking hole is also in an elongated shape. After the positions of the first clamp hook 301 and the second clamp hook 302 are adjusted, the lower railing is placed at the innermost part of the first accommodating space, and then bolts are passed through the two first locking holes, and the bolts are abutted against the lower railing. The lower railing is locked in the first accommodating space through the cooperation of the bolts and the first locking holes, 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.

[0057] like Figure 5 As shown, in one embodiment, it also includes:

[0058] The second clamping assembly 4 is arranged 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 and arranged to form a hook portion 401, and a second accommodating space is formed between the inner walls of the hook portion 401, and the second accommodating space is adapted to accommodate the upper railing. The oblique beam 1 is connected to the upper railing through the second clamping assembly 4, wherein the second accommodating space is adapted to accommodate the upper railing, thereby increasing the stability of the connection between the oblique beam 1 and the upper railing and increasing the stability of the overall structure.

[0059] 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 the two side edges 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 abutted against 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.

[0060] In one embodiment, a second adjustment hole 402 is formed on the second clamping assembly 4; the second adjustment hole 402 is in a strip shape; the second clamping assembly 4 is connected to the inclined beam 1 through the second adjustment hole 402. The second clamping assembly 4 is connected to the inclined beam 1 through the second adjustment hole 402, which can compensate for errors generated during the installation of the inclined beam 1 and increase the error tolerance.

[0061] 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.

[0062] It should be noted that the first clamping assembly 3 and the second clamping assembly 4 are made of stainless steel.

[0063] In one embodiment, it further includes:

[0064] There is at least one crossbar 5, which is arranged between adjacent inclined beams 1. The length of the crossbar 5 is fixed, and the crossbar 5 can act as a sizing effect, and there is no need to measure and locate during the installation process, thereby simplifying the installation process and increasing convenience.

[0065] It should be noted that a plurality of through holes are provided in the middle of the crossbar 5 for fixing a micro inverter, and the micro inverter is suitable for connecting to the photovoltaic panel 8 and for converting between direct current and alternating current.

[0066] like Figure 6 As shown, in one embodiment, it also includes:

[0067] An angle code 6 is provided at the end of the cross bar 5; the cross bar 5 is fixedly connected to the oblique beam 1 through the angle code 6. The cross bar 5 is fixedly connected to the oblique beam 1 through the angle code 6, further increasing the stability of the connection between the cross bar 5 and the oblique beam 1.

[0068] It should be noted that bolt holes are provided at the ends of the crossbar 5, and bolt holes also begin to be provided at positions corresponding to the crossbar 5 on the inclined beam 1. The angle bracket 6 is specifically an L-shaped plate, one side of the angle bracket 6 is fixedly connected to the crossbar 5 by bolts, and the other side of the angle bracket 6 is fixedly connected to the inclined beam 1. The crossbar 5 is fixedly connected to the inclined beam 1 by the angle bracket 6. In this way, the exposed and protruding parts are reduced, so that the overall structure is more concise and clear.

[0069] like Figure 7 As shown, in one embodiment, the oblique beam 1 and the oblique brace 2 are both C-shaped open alloy profiles; the oblique beam 1 and the oblique brace 2 are fixedly connected by bolts; the bolt sleeve 7 is sleeved on the outside of the bolt, and the two ends of the bolt sleeve 7 abut against the inner wall of the oblique brace 2. By adding the bolt sleeve 7, the bolt sleeve 7 abuts against the inner side of the oblique brace 2, which can increase the local strength of the node, avoid bending and the like, and increase the overall life.

[0070] 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, and the overall structure is simpler.

[0071] It should be noted that all aluminum alloy profiles are black anodized. The remaining parts are also painted black.

[0072] 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.

[0073] According to an embodiment of the present invention, on the other hand, a method for installing a photovoltaic bracket is provided, comprising the photovoltaic bracket device described in any one of the above, and further comprising the following steps:

[0074] The inclined beam 1 and the diagonal brace 2 are pre-processed in the factory, and the diagonal brace 2 is in a storage state during transportation; the inclined beam 1 and the diagonal brace 2 are opened to a suitable angle on site, so that the diagonal brace 2 is in a supporting state; the first end of the inclined beam 1 is fixed to the upper railing; the second end of the diagonal brace 2 is fixed to the lower railing. Compared with the traditional solution, this solution uses the diagonal brace 2 and the inclined beam 1 to cooperate with each other for installation, which reduces the type and quantity of profiles, reduces costs, and the diagonal brace 2 is in a storage state during transportation, and when the diagonal brace 2 is in the storage state, it is completely located in the installation groove, and the overall occupied space is greatly reduced, thereby reducing packaging and transportation costs.

[0075] In an optional implementation, it also includes:

[0076] After the inclined beam 1 and the inclined brace 2 are opened to a suitable angle, the inclined beam 1 and the inclined brace 2 are fixed by bolts;

[0077] When the second end of the diagonal brace 2 is fixed to the lower railing, the relative positions of the first clamping hook 301 and the second clamping hook 302 are changed through the first adjustment hole 303, thereby controlling the size of the first accommodation space, thereby ensuring that the first accommodation space has the same size as the lower railing;

[0078] Fix the photovoltaic panel 8 on the inclined beam 1 through the mounting holes;

[0079] Two adjacent inclined beams 1 are connected to each other through a cross bar 5, wherein the inclined beam 1 and the cross bar 5 are fixedly connected through an angle bracket 6;

[0080] Tighten all bolts to complete the installation.

[0081] Although the embodiments of the present invention have been described in conjunction with 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 are all within the scope defined by the appended claims.
