Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic equipment, and in particular to a fixing component. Background Art

[0002] With the rapid development of the photovoltaic industry, the demand for reducing the cost of photovoltaic frames is increasing. The industry has adopted the method of eliminating the C side of the aluminum alloy frame or reducing the width of the C side (that is, the bottom side of the C-shaped frame profile) or using a lower-cost composite material frame to achieve weight reduction and cost reduction. Composite materials have the characteristics of anisotropy, resulting in the risk of hidden cracks if the installation hole is opened on the bottom side of the C-shaped composite material frame. Therefore, most composite material frames also adopt the method of eliminating the C side of the frame or reducing the width of the C side of the frame.

Even if some photovoltaic frames are equipped with pressure blocks for fastening during installation, the installation of pressure blocks alone cannot solve the current photovoltaic frames' problems of insufficient overall structural strength, poor stability, and difficulty in installation.

[0028] The present application provides a fixing assembly for mounting a photovoltaic assembly on a mounting beam, the fixing assembly comprising a pressing block, a first fixing block and a first frame profile. The pressing block comprises a first groove, the opening direction of the first groove is perpendicular to the extension direction of the first frame profile. The first fixing block comprises a first side portion and a second side portion, the first side portion and the second side portion are arranged at a preset angle. In the installed state, the first frame profile is accommodated in the space enclosed by the first groove and the first side portion, and the second side portion is fixedly connected to the mounting beam. The fixing assembly of the present application does not require drilling holes on the frame profile, so that the frame profile can be selected from composite material, the fixing assembly has a stable structure and is easy to install, and is particularly suitable for the stable installation of frame profiles that eliminate the C-side or reduce the width of the C-side of the frame.

[0029] According to an exemplary embodiment, Figure 1 As shown, the left side of the figure is a structural diagram in the installed state, and the right side is an exploded diagram. This embodiment is the first embodiment. A fixing component is provided in the embodiment for installing the photovoltaic component on the mounting beam 900. The fixing component includes a pressing block 100, a first fixing block 200, a first frame profile 300 and a fixing member 400.

[0030] In this embodiment, if Figure 1As shown, the shape of the pressing block 100 is roughly a C-shaped pressing block, and the pressing block 100 includes a first groove 110, a first groove edge 120 and a second groove edge 130. The opening direction of the first groove 110 is perpendicular to the extension direction of the first frame profile 300, and the first groove edge 120, the second groove edge 130 and the groove bottom edge together constitute the first groove 110. The first fixing block 200 includes a first side portion 210 and a second side portion 220, and the first side portion 210 and the second side portion 220 are arranged at a preset angle, and the preset angle can be 30°-150°. In the installed state, the first frame profile 300 is accommodated in the space enclosed by the first groove 110 and the first side portion 210, and the second side portion 220 is fixedly connected to the mounting beam 900. Through the above arrangement, there is no need to punch holes on the first frame profile 300, so that the frame profile can be selected from composite materials that cancel the C edge or reduce the width of the C edge of the frame, so that the frame profile monomer has a small weight, less material, low cost, and no punching process is required, which reduces the difficulty of processing. In addition, the dual measures of using the pressure block 100 and the first fixing block 200 to jointly fasten the first frame profile 300 and using the second side 220 of the first fixing block 200 to fix the connection with the mounting beam 900 not only realize the bolt installation of the frame profile, but also have the fastening effect of the pressure block installation, thereby ensuring the structural stability of the fixed assembly and being able to cope with the special requirements of extreme environments such as at sea or in stormy areas.

[0031] In this embodiment, the first frame profile 300 is a composite frame with the C edge eliminated or the C edge width reduced. Figure 1 As shown, the first frame profile 300 includes a top 310, a cavity 320 and a bottom edge 330. The space formed below the top 310 and above the cavity 320 is a location for installing photovoltaic modules. Among them, the first groove edge 120 is arranged flush with the top 310 of the first frame profile 300. In the installed state, the top of the first frame profile 300 abuts against the first groove edge 120. The first groove edge 120 adopts a flat head design, which can make the first frame profile 300 easier to enter and more convenient to install. The first edge 210 in the first fixing block 200 can provide resistance when the side wall of the cavity 320 is under pressure, ensuring that the cavity 320 does not deform.

[0032] like Figure 1As shown, in the installed state, the second side portion 220 is located above the second groove side 130, and the second side portion 220 and the second groove side 130 are fixedly connected to the mounting beam 900 through the fixing member 400. The fixing member 400 can be selected from the commonly used bolt connection, and the fixing member 400 includes a screw 410 and a nut 420. Correspondingly, the second side portion 220 and the second groove side 130 are both provided with bolt holes, and the screw 410 is inserted into the second side portion 220, the second groove side 130, and the mounting beam 900 in sequence and then screwed with the nut 420. By setting the bolt connection to connect the second side portion 220 and the second groove side 130 with the mounting beam 900, the overall structural stability is improved, and at the same time, it is convenient for the corresponding matching installation of the ground power station and the offshore high wind wave power station installed by bolt connection.

[0033] In this embodiment, if Figure 1 As shown, the first side portion 210 and the second side portion 220 are connected with a first abutting groove 211, the end of the second side portion 220 is provided with a second abutting groove 221, and the end of the second groove side 130 is provided with an abutting protrusion 131. In the installed state, the first abutting groove 211 abuts with the end of the bottom edge 330 of the first frame profile 300, so that the first side portion 210 and the side wall of the cavity 320 of the first frame profile 300 are gap-matched, and the second abutting groove 221 abuts with the abutting protrusion 131, so that the second side portion 220 and the second groove side 130 are gap-matched. By providing the first abutting groove 211, while accommodating the bottom edge 330 of the first frame profile 300, a certain gap is also provided between the first side portion 210 and the side wall of the cavity 320 of the first frame profile 300, ensuring that a certain deformation space exists for the first fixing block 200 in the installed state. By setting the second abutment groove 221 to abut against the abutment protrusion 131, the end of the second groove edge 130 limits the second side portion 220, and the second side portion 220 and the second groove edge 130 are gap-matched, so that the first frame profile 300 has a certain activity space for stress release when subjected to load, thereby avoiding fracturing of the bottom edge 330 of the first frame profile 300.

[0034] The material of the pressing block 100 and the first fixing block 200 in this embodiment can be selected from one of aluminum alloy, galvanized steel, galvanized magnesium aluminum steel, nylon, PPO (Polyphenylene Oxide), PEEK (Polyetheretherketone), PMMA (Polymethylmethacrylate), ABS (Acrylonitrile Butadiene Styrene), HDPE (High Density Polyethy l ene), PPS (Polyphenylene sulfide), and PES (Polyethersulfone). All of the above materials have good mechanical properties, low density, and high structural strength. When the material of the pressing block 100 and the first fixing block 200 is selected from one of aluminum alloy, galvanized steel, and galvanized magnesium aluminum steel, they can be made by melt extrusion molding; when the material of the pressing block 100 and the first fixing block 200 is selected from one of nylon, PPO, PEEK, PMMA, ABS, HDPE, PPS, and PES, they can be made by adding 10-30% of short glass fiber, basalt fiber, or carbon fiber reinforcement and then injection molding.

[0035] Specifically, in production and use, the overall width of the fixing assembly can be set to 30-80 mm (i.e., the length of the second groove edge 130), the material thickness of the pressing block 100 and the first fixing block 200 is 2-6 mm, and the width of the first fixing block 200 in the extension direction of the first frame profile 300 is less than or equal to the width of the pressing block 100. The actual value is set according to production needs, and this application does not limit this.

[0036] like Figure 2 As shown, the left side of the figure is a structural diagram in the installation state, and the right side is an exploded view. This embodiment is the second embodiment. The similarities between this embodiment and the first embodiment are not repeated here. The difference is that in this embodiment, at least one mounting boss 212 is provided on the first side portion 210, and the side wall of the cavity 320 of the first frame profile 300 is correspondingly provided with at least one mounting hole 311. In the installation state, the mounting boss 212 is inserted into the mounting hole 311, so that the first fixing block 200 is plug-connected with the first frame profile 300 to form a stable structure. The above-mentioned arrangement increases the structural stability of the fixing assembly, reduces the stress on the first frame profile 300, and at the same time, it plays a limiting role on the first frame profile 300 before the bolt is installed, preventing the components in the fixing assembly from slipping during installation. The number of mounting bosses 212 is the same as that of mounting holes 311, which is two in the figure, and can actually be set according to needs.

[0037] In this embodiment, a receiving groove 222 is further provided at the connection between the first side portion 210 and the second side portion 220. The receiving groove 222 is used to receive the end of the bottom edge 330 of the first frame profile 300, and the receiving groove 222 is clearance-matched with the end of the bottom edge 330 of the first frame profile 300. The function of the receiving groove 222 is equivalent to the function of the first abutting groove 211 in the first embodiment. By providing the receiving groove 222, the end of the bottom edge 330 of the first frame profile 300 can be protected from being crushed when being pressed. In addition, since the mounting boss 212 is provided to be plug-connected with the mounting hole 311, the mounting boss 212 and the second abutting groove 221 are no longer required in this embodiment, thereby reducing the difficulty of processing.

[0038] like Figure 3 As shown, the left side of the figure is a structural diagram in the installation state, and the right side is an exploded diagram. This embodiment is the third embodiment. The similarities between this embodiment and the above two embodiments are not repeated. The difference is that in this embodiment, the first side portion 210 is provided with a first clamping groove 213 and a second clamping groove 214 in sequence. In the installation state, the end of the bottom edge 330 of the first frame profile 300 is clamped with the first clamping groove 213, and the end of the bottom edge 330 of the first frame profile 300 is gap-matched with the first clamping groove 213, and the end of the second groove side 130 is clamped with the second clamping groove 214, and the end of the second groove side 130 is gap-matched with the second clamping groove 214. Among them, the inner wall of the second clamping groove 214 is provided with a clamping protrusion 215, and the end of the second groove side 130 is correspondingly provided with a clamping hole 132, and the clamping protrusion 215 is inserted into the clamping hole 132 to form a connection. Through the above arrangement, the pressing block 100 and the first fixing block 200 can form a stable structure, the length of the second groove edge 130 can be reduced to save costs, and there is no need to open bolt holes on the second groove edge 130 .

[0039] In this embodiment, a weight-reducing groove 216 is further provided on the first side portion 210, and the weight-reducing groove 216 is provided to reduce the overall material of the first fixing block 200 and reduce the cost. At the same time, in this embodiment, the preset angle of the first side portion 210 and the second side portion 220 can be set to 120°-150° to increase the operating space when the screw 410 is installed, so as to facilitate the insertion of the screw 410.

[0040] like Figure 4As shown, the left side of the figure is a structural diagram in the installation state, and the right side is a structural schematic diagram of the pressing block 100 in this embodiment. This embodiment is the fourth embodiment. The similarities between this embodiment and the first embodiment are not repeated. The difference is that in this embodiment, the fixing assembly also includes a second fixing block 500 and a second frame profile 600. The pressing block 100 is roughly an I-shaped pressing block. The pressing block 100 also includes a second groove 140. The opening direction of the second groove 140 is opposite to the opening direction of the first groove 110. The second groove 140 is axially symmetrical with the first groove 110. In the installation state, the second fixing block 500 and the second frame profile 600 are axially symmetrical with the first fixing block 200 and the first frame profile 300 about the symmetry axis of the second groove 140 and the first groove 110. This embodiment solves the installation problem of two frame profiles arranged in parallel. The pressing block 100 is equivalent to the function of the middle pressing block in the current conventional pressing block installation operation. Through the above arrangement, the total amount of the fixing assembly can be reduced, the installation cost can be reduced, and the pressing block structure of the integrated I-shaped design is more stable.

[0041] like Figure 5 and Figure 6 As shown, the fifth and sixth embodiments are the same in principle as the fourth embodiment, and are all designed with an integrated I-shaped pressure block based on the second and third embodiments to simultaneously realize the installation of two parallel arranged frame profiles, so that the overall fixing component uses less material, has lower cost, and has a more stable structure, which will not be elaborated in this application.

[0042] In summary, the fixing assembly of the present application uses a combination of a pressing block and a fixing block, so that the frame profile can be selected from a composite material frame that cancels the C edge or reduces the width of the C edge of the frame, reduces the weight of the single frame profile, reduces the cost, and sets a pressing block and a fixing block to install the bolts externally, so as to achieve no installation holes on the frame profile, so that the frame profile can be installed stably, and the stability of the fixing assembly installation structure is improved, which is fully prepared for extreme weather. The gap design of the fixing block effectively guarantees the quality of the bottom end of the frame profile and prevents it from cracking under stress, and at the same time leaves space for stress release after the frame profile is stressed, so that the frame profile has stronger anti-deformation ability. The fixing assembly of the present application is not only suitable for composite material frames that cancel the C edge or reduce the width of the C edge of the frame, but also compatible with conventional aluminum alloy frames with long C edges, and has a wide range of applications.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present disclosure.
