Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a photovoltaic component installation structure. [Background technology]

[0002] Household photovoltaic power stations are mainly built on household roofs and courtyards. The domestic market is huge, but household roofs are limited by house quality and installation area, and there is a problem of small installation scale of power stations, which restricts the installation of some roofs.

[0003] The truss scheme for building across houses has been widely promoted. Photovoltaic modules are installed on the truss, where the photovoltaic modules are fixed with a pressure plate assembly, and the pressure plate is fixed to the installation beam with bolts. This requires construction workers to install under the installation beam, which is not easy to install and difficult to work at high places. In addition, ordinary pressure plates need to be installed on photovoltaic modules, and construction workers install across photovoltaic modules, which is easy to cause damage to the modules. [Contents of the utility model]

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a photovoltaic component installation structure that is easy to install, thereby solving the problems of great construction difficulty and low construction efficiency.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A photovoltaic assembly mounting structure that is easy to install, two photovoltaic assemblies are mounted side by side on a mounting beam, the photovoltaic assemblies have a frame, a pressure plate assembly is connected between the two photovoltaic assemblies, the pressure plate assembly includes a pressure plate and fasteners connecting the pressure plate to the mounting beam, a self-locking structure is provided between the frame of one of the two photovoltaic assemblies and the pressure plate, and the frame of the other photovoltaic assembly is connected to the pressure plate via the self-locking structure or is pressed onto the mounting beam by the pressure plate.

[0007] Preferably, the self-locking structure includes an upper buckle provided on the frame of the photovoltaic module and a lower buckle provided on the pressure plate. When the photovoltaic module is installed, the upper buckle and the lower buckle are buckled and fixed.

[0008] Preferably, the pressure plate is provided with a limiting slot, and the lower buckle is arranged on a side of the limiting slot.

[0009] Preferably, a gap is provided between the B side and the C side of the photovoltaic module frame, the upper buckle is provided at the lower end of the B side, and the lower buckle is inserted into the gap to cooperate with the upper buckle.

[0010] Preferably, the pressure plate is provided with a supporting flange cooperating with the mounting beam on the bottom surface of one side where the lower buckle is provided; and / or the pressure plate is a stainless steel profile.

[0011] Preferably, when another photovoltaic component frame is pressed onto the mounting beam by the pressing plate, a pressing and limiting structure is provided between the photovoltaic component frame and the pressing plate.

[0012] Preferably, the pressing and limiting structure includes a limiting groove provided on the C-side of the photovoltaic module frame, and a limiting pressing edge provided on the pressing plate and cooperating with the limiting groove.

[0013] Preferably, the fastener is a U-shaped bolt, a fixing hole is provided on the pressure plate, and the U-shaped bolt includes a U-shaped screw rod that is engaged with the mounting beam, and a screw head at the mouth of the U-shaped screw rod passes through the fixing hole and is connected with a nut.

[0014] Preferably, a washer is provided between the nut and the pressure plate; and / or the mounting beam is square steel, U-shaped steel or C-shaped steel.

[0015] Preferably, the mounting beam is arranged on a truss, and the truss is mounted on the roof.

[0016] The utility model adopts the above technical solution and has the following beneficial effects:

[0017] 1. A self-locking structure is provided between the frame of one of the two photovoltaic modules and the pressure plate, and the frame of the other photovoltaic module is connected to the pressure plate through the self-locking structure or is pressed onto the mounting beam by the pressure plate.

[0018] When the two photovoltaic module frames and the pressure plate are connected by a self-locking structure, during on-site installation, the pressure plate can first be connected to the mounting beam by fasteners, and then the photovoltaic module can be fixed to the mounting beam by relying on the self-locking structure between the pressure plate and the two adjacent photovoltaic module frames.

[0019] The advantage of using a self-locking structure for installation is that the photovoltaic modules can be directly placed in place. The self-locking structure can achieve self-locking fixation without the need for additional fixation through other fasteners, and construction workers do not need to cross photovoltaic modules for installation.

[0020] A self-locking structure is provided between the frame of one photovoltaic module and the pressure plate, and when the frame of the other photovoltaic module is pressed onto the mounting beam by the pressure plate, during on-site installation, the frame 1 of the previous photovoltaic module is fixed to the mounting beam by the pressure plate, and then the next adjacent photovoltaic module is installed, and the frame 2 of the next photovoltaic module is tightly connected to the pressure plate through the self-locking structure. Compared with the scheme of setting the self-locking structure on both sides, this scheme of setting the self-locking structure on one side has a simpler structure and is more convenient to install.

[0021] Therefore, the utility model can improve the installation efficiency of photovoltaic components and thus speed up the construction of power stations, reduce the probability of component damage, reduce the difficulty of construction, and effectively reduce the risks of construction personnel.

[0022] 2. The self-locking structure includes an upper buckle arranged on the frame of the photovoltaic module and a lower buckle arranged on the pressure plate. Therefore, when installing the photovoltaic module, the photovoltaic module is directly placed, and the upper buckle and the lower buckle are automatically buckled and fixed, without the need for additional fixation through fasteners, which facilitates installation.

[0023] 3. Since a limit slot is provided on the frame of the photovoltaic module and the lower buckle is provided on the side of the limit slot, after the self-locking structure completes self-locking, the upper buckle is limited by the limit slot at the same time, and the upper buckle and the lower buckle are not easy to separate.

[0024] 4. Since there is a gap between the B side and the C side of the photovoltaic module frame, the upper buckle is set at the lower end of the B side, and the lower buckle is inserted into the gap and matched with the upper buckle. In this way, the B side has a certain elasticity, which is convenient for the upper buckle to be inserted into the limit slot and buckled with the lower buckle. In addition, unlike the conventional frame where the C side protrudes from the side of the B side, here the C side is limited and matched with the side of the pressure plate, combined with the relative limit effect between the upper buckle and the lower buckle, it can effectively prevent the horizontal displacement between the pressure plate and the photovoltaic module frame.

[0025] 5. Since a supporting convex edge cooperating with the mounting beam is provided on the bottom surface of one side where the lower buckle is set, it can be ensured that after the fastener fastens the pressure plate, the supporting convex edge cooperates with the mounting beam to ensure that the pressure plate is firmly supported on the mounting beam, and the pressure plate ensures the compression of the frame.

[0026] 6. When another photovoltaic module frame is pressed onto the mounting beam by the pressure plate, a pressing and limiting structure is provided between the photovoltaic module frame and the pressure plate. The pressing and limiting structure can not only press the photovoltaic module tightly, but also prevent the photovoltaic module from relative displacement.

[0027] 7. The pressing and limiting structure includes a limiting groove arranged on the C side of the frame of the photovoltaic module, and a limiting pressure edge arranged on the pressure plate and matched with the limiting groove. During installation, after the photovoltaic module is placed in place on the mounting beam, the pressure plate is placed so that the limiting pressure edge matches the limiting groove, and then the pressure plate is fixed by fasteners so that the limiting pressure edge is pressed into the limiting groove. In addition, the pressing and limiting structure can not only press the photovoltaic module, but also play a limiting role to avoid horizontal movement of the photovoltaic module, and also has the function of ensuring the relative position of the lower buckle and the upper buckle.

[0028] 8. U-bolts are used as fasteners, and the operation of tightening the nuts is carried out above the mounting beam, which is convenient for tightening and does not require construction workers to install under the mounting beam.

[0029] 9. The mounting beam is set on the truss, and the truss is installed above the roof, so the photovoltaic power station can be built across the house to avoid being restricted by the house quality and installation area.

[0030] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0040] Referring to the prior art, photovoltaic modules arranged in a rectangular shape are installed in an array on a photovoltaic support, and the photovoltaic support is provided with a mounting beam.

[0041] Embodiment 1

[0042] Reference Figure 1 and Figure 2 As shown, a photovoltaic assembly installation structure that is easy to install, two photovoltaic assemblies 3 are installed side by side on the installation beam 6, where the installation beam is usually a horizontal beam, of course, it can also be a longitudinal beam, and multiple pairs of photovoltaic assemblies are arranged side by side along the extension direction of the installation beam. The photovoltaic assembly has a frame, and a pressure plate assembly is connected between two adjacent photovoltaic assemblies. Here, the two adjacent photovoltaic assemblies are respectively the first photovoltaic assembly and the second photovoltaic assembly, and have a first assembly frame 1 and a second assembly frame 2 respectively. The pressure plate assembly includes a pressure plate 5 and a fastener connecting the pressure plate 5 to the installation beam 6. A self-locking structure is provided between the frame of one of the two photovoltaic assemblies and the pressure plate, and the frame of the other photovoltaic assembly is connected to the pressure plate through the self-locking structure or is pressed onto the installation beam by the pressure plate.

[0043] In this embodiment, a self-locking structure is provided between the first assembly frame 1 and the pressure plate 5, and the second assembly frame 2 is pressed by the pressure plate 5 onto the mounting beam 6. In another embodiment, the two photovoltaic assembly frames and the pressure plate are connected via a self-locking structure.

[0044] When the two photovoltaic module frames and the pressure plate are connected by a self-locking structure, during on-site installation, the pressure plate can first be connected to the mounting beam by fasteners, and then the photovoltaic module can be fixed to the mounting beam by relying on the self-locking structure between the pressure plate and the two adjacent photovoltaic module frames.

[0045] The advantage of using a self-locking structure for installation is that the photovoltaic modules can be directly placed in place. The self-locking structure can achieve self-locking fixation without the need for additional fixation through other fasteners, and construction workers do not need to cross photovoltaic modules for installation.

[0046] A self-locking structure is provided between the frame of one photovoltaic module and the pressure plate, and when the frame of the other photovoltaic module is pressed onto the mounting beam by the pressure plate, during on-site installation, the frame 1 of the previous photovoltaic module is fixed to the mounting beam by the pressure plate, and then the next adjacent photovoltaic module is installed, and the frame 2 of the next photovoltaic module is tightly connected to the pressure plate through the self-locking structure. Compared with the scheme of setting the self-locking structure on both sides, this scheme of setting the self-locking structure on one side has a simpler structure and is more convenient to install.

[0047] Therefore, the utility model can improve the installation efficiency of photovoltaic components and thus speed up the construction of power stations, reduce the probability of component damage, reduce the difficulty of construction, and effectively reduce the risks of construction personnel.

[0048] Furthermore, when another photovoltaic module frame is pressed onto the mounting beam by the pressure plate, a pressing and limiting structure is provided between the photovoltaic module frame and the pressure plate. Specifically, a pressing and limiting structure is provided between the first module frame 1 and the pressure plate 5, and a self-locking structure is provided between the second module frame 2 and the pressure plate 5. In this way, during on-site installation, the frame 1 of the previous photovoltaic module is fixed to the mounting beam by the pressing and limiting structure, and then the next adjacent photovoltaic module is installed, and the frame 2 of the next photovoltaic module and the pressure plate are tightly connected by the self-locking structure.

[0049] Specifically, the self-locking structure includes an upper buckle 21 provided on the second component frame 2 and a lower buckle 52 provided on the pressure plate 5. When the photovoltaic component is installed, the upper buckle and the lower buckle are buckled and fixed. Therefore, when the photovoltaic component is installed, the photovoltaic component is directly placed, and the upper buckle and the lower buckle are automatically buckled and fixed, and no additional fixation by fasteners is required, which facilitates installation. It can be understood that the structure of the upper buckle 21 and the lower buckle 52 can refer to the prior art, and here the upper buckle 21 and the lower buckle 52 adopt the form of corresponding buckled hooks. The self-locking structure in this embodiment selects mechanical self-locking. Of course, other variations of the self-locking structure can refer to the prior art, which will not be described one by one here.

[0050] Furthermore, a limiting slot 53 is provided on the side of the pressing plate 5 close to the second component frame, and the lower buckle 52 is provided on the side of the limiting slot. Since the lower buckle is provided on the side of the limiting slot, after the self-locking structure completes self-locking, the upper buckle is also limited by the limiting slot, and the upper buckle and the lower buckle are not easy to separate.

[0051] Furthermore, a gap is provided between the B side 201 and the C side 202 of the second component frame 2, the upper buckle 21 is provided at the lower end of the B side, and the lower buckle 52 is inserted into the gap and matched with the upper buckle 21. In this way, since the B side has a certain elasticity, it is convenient for the upper buckle to be inserted into the limiting slot and to be buckled with the lower buckle. In addition, unlike the conventional frame where the C side protrudes from the side of the B side, here the C side is limitedly matched with the side of the pressure plate, and combined with the relative limiting effect between the upper buckle and the lower buckle, the horizontal displacement between the pressure plate and the photovoltaic component frame can be effectively prevented.

[0052] Furthermore, the bottom surface of the pressing plate 5 on one side where the self-locking structure is set is provided with a supporting flange 54 that cooperates with the mounting beam. It can be ensured that after the fasteners fasten the pressing plate, the supporting flange cooperates with the mounting beam to ensure that the pressing plate is firmly supported on the mounting beam, and the pressing plate ensures that the frame is pressed tightly.

[0053] As for the design of the pressing and limiting structure, specifically, the pressing and limiting structure includes a limiting groove 11 provided on the C side of the frame of the photovoltaic module, and a limiting pressing edge 51 provided on the pressing plate and matched with the limiting groove 11. During installation, after the photovoltaic module is placed in place on the mounting beam, the pressing plate is placed so that the limiting pressing edge matches the limiting groove, and then the pressing plate is fixed by fasteners so that the limiting pressing edge 51 is pressed into the limiting groove 11. In addition, the pressing and limiting structure can not only press the photovoltaic module, but also play a limiting role to prevent the photovoltaic module from moving in the horizontal direction, and also has the function of ensuring the relative position of the lower buckle and the upper buckle.

[0054] As an embodiment, the fastener is a U-bolt 4, a fixing hole is provided on the pressure plate 5, and the U-bolt includes a U-shaped screw 41 that is engaged with the mounting beam, and a screw head at the mouth of the U-shaped screw passes through the fixing hole and is connected with a nut 42. The U-bolt is used as the fastener, and since the nut is located above the mounting beam, the operation of tightening the nut is performed above the mounting beam, which is convenient for tightening and does not require construction personnel to install under the mounting beam.

[0055] Furthermore, a washer 43 is provided between the nut 42 and the pressing plate 5 to prevent the nut from loosening and increase the reliability of fastening.

[0056] For the truss solution for building across houses, the mounting beam 6 is installed on the truss 7, and the truss 7 and the mounting beam 6 are connected by welding or bolts. In addition, the truss is installed above the roof, that is, it completely spans the roof. Therefore, a photovoltaic power station can be built across houses, avoiding restrictions on house quality and installation area. Of course, it can also be applied to other installation scenarios.

[0057] As an embodiment, the pressing plate 5 and the component frame are made of stainless steel profiles, and the mounting beam 6 is made of square steel, U-shaped steel or C-shaped steel. Compared with aluminum alloy materials, the cost is lower. Of course, it is understandable that other conventional materials and structures can also be used.

[0058] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
