Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to a photovoltaic module connection structure and a photovoltaic support. Background Technology

[0002] In recent years, in response to the national call for energy conservation and emission reduction, provinces and cities have erected several photovoltaic brackets in wasteland and abandoned fish ponds, and installed several photovoltaic modules in parallel between the photovoltaic brackets through connecting structures, forming a huge solar energy receiving surface, making full use of the natural environment and green energy.

[0003] Existing photovoltaic (PV) mounting systems are divided into rigid and flexible systems. Rigid PV systems are more widely used due to their relatively lower construction difficulty and cost. Existing rigid PV systems use a concrete base as a carrier, with support columns fixed to the base by bolts. Then, mounting surfaces are erected between several parallel support columns using connectors to connect and install several PV modules side-by-side onto these support systems. The existing PV module connection structure uses a large number of bolts, nuts, lock rings, and anti-loosening rings during assembly, making the installation process quite cumbersome. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a photovoltaic module connection structure and photovoltaic bracket to solve the problem that the installation process is complicated by the use of a large number of bolts, nuts, anti-loosening rings and other parts.

[0005] To achieve the above objectives, this utility model provides a photovoltaic module connection structure for fixing a support base and a photovoltaic module to two adjacent support columns. The photovoltaic module connection structure includes a connecting portion disposed on the support base, the connecting portion being used to fix the photovoltaic module between two support bases. The photovoltaic module connection structure further includes:

[0006] A connecting strip that can be detachably installed between the two connecting parts.

[0007] The connecting part includes:

[0008] A double-sided connecting strip is provided on the top of the support base, and two mating grooves are provided on the double-sided connecting strip, which are used to fit and install photovoltaic modules.

[0009] A support connector is provided between the top of the support base and the bottom of the double-sided connecting strip, the support connector being used to fix the double-sided connecting strip to the top of the support base.

[0010] A limiting connector is provided between the top ends of the connecting strip and the two bilateral connecting strips. The limiting connector is used to fix the connecting strip between the top ends of the two bilateral connecting strips, and to limit and fix the photovoltaic module by the connecting strip.

[0011] Preferably, the top and bottom of the fitting groove are open and closed, respectively, and a drainage groove is provided at the bottom of the fitting groove.

[0012] Preferably, the support connector includes:

[0013] A first connecting strip is fixedly disposed at the bottom of the double-sided connecting strip, and a first slot is provided between two opposite vertical surfaces on the outside of the first connecting strip.

[0014] A vertical plate is inserted horizontally into the first slot, and the top of the vertical plate is fixedly disposed at the bottom of the support base.

[0015] Two spline grooves are provided through the vertical plate and the first connecting strip, and spline bolts are inserted between the two spline grooves.

[0016] A nut with a threaded sleeve on one end of the spline bolt.

[0017] A second connecting strip is fixedly installed at the bottom of the double-sided connecting strip. The second connecting strip has a second slot, and one of the boundaries of the support base is inserted laterally into the second slot.

[0018] Preferably, the first slot and the spline groove are located on two adjacent vertical surfaces of the first connecting strip.

[0019] Preferably, the first connecting strip and the second connecting strip are parallel to each other, and the first connecting strip and the second connecting strip are distributed on opposite sides of the outside of the support base.

A horizontal slot is provided between the two end faces of the connecting strip. One end of the protruding strip is slidably sleeved in the horizontal slot. A first vertical groove is provided between the top and end face of the double-sided connecting strip. A second vertical groove is provided between the top and end face of the connecting strip. The first vertical groove and one or two second vertical grooves together form a limiting insertion hole. A limiting insert is vertically inserted into the limiting insertion hole.

[0021] Preferably, the first vertical groove is located between the two protrusions, and the bottom of the first vertical groove is lower than the bottom of the fitting groove.

[0022] A photovoltaic support structure includes a concrete base, a support column, a support base, and the aforementioned photovoltaic module connection structure, wherein the photovoltaic module connection structure is disposed at the top of the support column and between two adjacent photovoltaic modules.

[0023] The beneficial effects of this utility model are as follows: This utility model forms an installation support surface by assembling and connecting two fitting grooves, support connectors, and limiting connectors that are relatively set on the double-sided connecting strips.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0034] like Figures 1 to 5 As shown, a photovoltaic module connection structure is used to fix a support base 4 and a photovoltaic module to two adjacent support columns 3. The photovoltaic module connection structure includes a connecting part 1 provided on the support base 4, which is used to fix the photovoltaic module between the two support bases 4. The photovoltaic module connection structure also includes:

[0035] A detachable connecting strip 2 is installed between two connecting parts 1. The connecting strip 2 is used to connect two adjacent connecting parts 1 and can limit and fix the photovoltaic module between the two adjacent connecting parts 1.

[0036] Connecting part 1 includes:

[0037] The double-sided connecting strip 11 is located on the top of the support base 4. Two fitting grooves 12 are provided on the double-sided connecting strip 11. The corners of the photovoltaic module can be fitted into the corresponding fitting grooves 12 on the two adjacent double-sided connecting strips 11. The fitting grooves 12 are used to fit and install the photovoltaic module.

[0038] A support connector 13 is provided between the top of the support base 4 and the bottom of the double-sided connecting strip 11. The support connector 13 is used to fix the double-sided connecting strip 11 to the top of the support base 4.

[0039] A limiting connector 14 is provided between the top of the connecting strip 2 and the top of the double-sided connecting strip 11. The limiting connector 14 is used to fix the connecting strip 2 between the tops of the two double-sided connecting strips 11, and to limit and fix the photovoltaic module by the connecting strip 2.

[0040] like Figures 1 to 3As shown, the top and bottom of the fitting groove 12 are open and closed, respectively, and a drainage groove is provided at the bottom of the fitting groove 12. The drainage groove is located on the closed opening inside the fitting groove 12. With this design, since the double-sided connecting strips 11 are inclined, and the trend between the open and closed openings of the fitting groove 12 is consistent with the inclination of the double-sided connecting strips 11, the photovoltaic module can be inserted into the open opening of the fitting groove 12 on the two adjacent double-sided connecting strips 11 after the double-sided connecting strips 11 are fixedly installed. After the photovoltaic module is fully inserted between the two adjacent double-sided connecting strips 11, the photovoltaic module will abut against the closed opening inside the fitting groove 12, thus initially completing the mechanical installation of the photovoltaic module. The drainage groove can drain the rainwater that seeps into the fitting groove 12, preventing rainwater from remaining in the fitting groove 12 for a long time and aggravating the aging of the corners of the photovoltaic module.

[0041] like Figure 3 As shown, the support connector 13 includes:

[0042] A first connecting strip 132 is fixedly installed at the bottom of the double-sided connecting strip 11, and a first slot 133 is provided between two opposite vertical surfaces on the outside of the first connecting strip 132.

[0043] A vertical plate 131 is horizontally inserted into the first slot 133, and the top of the vertical plate 131 is fixedly located at the bottom of the support base 4.

[0044] Two spline grooves 134 are provided through the vertical plate 131 and the first connecting strip 132, and spline bolts 135 are inserted between the two spline grooves 134.

[0045] A nut 136 is threaded onto one end of the spline bolt 135.

[0046] A second connecting strip 137 is fixedly installed at the bottom of the double-sided connecting strip 11. A second slot 138 is provided on the second connecting strip 137. One of the boundaries of the support base 4 is transversely inserted into the second slot 138.

[0047] The first slot 133 and the spline slot 134 are located on two adjacent vertical surfaces of the first connecting bar 132, respectively.

[0048] The first connecting strip 132 and the second connecting strip 137 are parallel to each other, and the first connecting strip 132 and the second connecting strip 137 are distributed on opposite sides of the outside of the support base 4.

[0049] During installation, first align the first slot 133 and the second slot 138 with the lower edge of the vertical plate 131 and the boundary of the support 4 opposite to the vertical plate 131, respectively. Then, horizontally push the double-sided connecting strip 11 so that the first slot 133 fits onto the outside of the bottom of the vertical plate 131, and the second slot 138 fits onto the outside of the boundary of the support 4, and so that the spline groove 134 on the vertical plate 131 corresponds to the spline groove 134 on the first connecting strip 132. Then, axially pass one end of the spline bolt 135 through the spline groove 134 on both slots in sequence. 4. Finally, thread the nut 136 onto the threaded end of the spline bolt 135 to fix the double-sided connecting strip 11 to the top of the support base 4. Then, insert the two opposite boundaries of the photovoltaic module into the openings of the corresponding fitting grooves 12 on the two adjacent double-sided connecting strips 11 until the photovoltaic module abuts against the closed opening inside the fitting groove 12. This completes the mechanical assembly of the photovoltaic module. The installation of the double-sided connecting strip 11 only uses one spline bolt 135 and nut 136, which greatly simplifies the installation steps without affecting the fixed connection effect.

[0050] like Figure 4 and Figure 5 As shown, the limiting connector 14 includes two protruding strips 141 that are fixed to one end of the top of the double-sided connecting strip 11. A horizontal slot 142 is provided between the two end faces of the connecting strip 2. The protruding strips 141 are slidably sleeved in one end of the horizontal slot 142. A first vertical groove 143 is provided between the top and end face of the double-sided connecting strip 11. A second vertical groove 144 is provided between the top and end face of the connecting strip 2. The first vertical groove 143 and one or two second vertical grooves 144 together form a limiting insertion hole. A limiting insert 145 is vertically inserted into the limiting insertion hole.

[0051] The first vertical groove 143 is located between the two protrusions 141, and the bottom of the first vertical groove 143 is lower than the bottom of the fitting groove 12.

[0052] After the photovoltaic module is fitted between two adjacent double-sided connecting strips 11, the connecting baffle 2 is then inserted horizontally between the tops of the two double-sided connecting strips 11, so that the protrusion 141 is inserted into the horizontal slot 142 on the connecting baffle 2, and the two adjacent vertical surfaces of the second vertical slot 144 and the first vertical slot 143 are flush. This allows the two to enclose and form a limiting insertion hole. Alternatively, the two connecting baffles 2 can be inserted opposite each other at the top of the same double-sided connecting strip 11, so that the first vertical slot 143 and the two second vertical slots 144 enclose and form a limiting insertion hole. Then, the limiting insertion strip 145 is inserted vertically from top to bottom into the limiting insertion hole. This operation can be repeated to achieve the desired result. Several parallel photovoltaic modules are fixed between several double-sided connecting strips 11. The connecting strip 2 is constrained by the cooperation between the protruding strip 141 and the horizontal slot 142, except for its length direction. The remaining degree of freedom of the connecting strip 2 is constrained by the cooperation between the limiting insert 145 and the limiting insert hole. Thus, the connecting strip 2 can be fixed between the tops of two adjacent double-sided connecting strips 11. At the same time, the fixed connecting strip 2 and the opening at the top of the sealing fitting groove 12 limit and fix the photovoltaic module between two adjacent double-sided connecting strips 11. Furthermore, no bolts, nuts, anti-loosening rings, or anti-loosening rings are needed during the assembly process, which greatly simplifies the assembly steps and improves the assembly efficiency.

[0053] Working principle: During installation, first align the first slot 133 and the second slot 138 with the lower edge of the vertical plate 131 and the boundary of the support base 4 opposite to the vertical plate 131, respectively. Then, push the double-sided connecting strip 11 horizontally so that the first slot 133 fits onto the outside of the bottom of the vertical plate 131, and the second slot 138 fits onto the outside of the boundary of the support base 4, so that the spline groove 134 on the vertical plate 131 corresponds to the spline groove 134 on the first connecting strip 132. Then, axially pass one end of the spline bolt 135 through the spline groove 134 on both slots in sequence, and finally thread the nut 136 onto the vertical plate 131. At the threaded end of the spline bolt 135, the double-sided connecting strip 11 can be fixed to the top of the support base 4. Then, the two opposite boundaries of the photovoltaic module are inserted into the openings of the corresponding fitting grooves 12 on the two adjacent double-sided connecting strips 11 until the photovoltaic module abuts against the closed opening inside the fitting groove 12. This completes the mechanical assembly of the photovoltaic module. Furthermore, the installation of the double-sided connecting strip 11 only uses one spline bolt 135 and nut 136, greatly simplifying the installation steps without affecting the fixing connection effect. After the photovoltaic module is fitted between two adjacent double-sided connecting strips 11, the connecting strip is laterally positioned... 2. The connector is inserted between the tops of two double-sided connecting strips 11, so that the protruding strip 141 is inserted into the horizontal slot 142 on the connecting strip 2, and the two adjacent vertical surfaces of the second vertical slot 144 and the first vertical slot 143 are flush. This allows the two to form a limiting insertion hole. Alternatively, the two connecting strips 2 can be inserted opposite each other at the top of the same double-sided connecting strip 11, so that the first vertical slot 143 and the two second vertical slots 144 form a limiting insertion hole. Then, the limiting insertion strip 145 is inserted vertically from top to bottom into the limiting insertion hole. This operation can be repeated to fix several parallel photovoltaic modules in several... Between the two double-sided connecting strips 11, the connecting stop 2 is constrained by the cooperation between the protruding strip 141 and the horizontal slot 142, except for its length direction. The remaining degree of freedom of the connecting stop 2 is constrained by the cooperation between the limiting insert 145 and the limiting insert hole. This fixes the connecting stop 2 between the tops of two adjacent double-sided connecting strips 11. At the same time, the fixed connecting stop 2 and the opening at the top of the sealing fitting groove 12 limit and fix the photovoltaic module between the two adjacent double-sided connecting strips 11. Furthermore, no bolts, nuts, anti-loosening rings, or anti-loosening rings are needed during the assembly process, which greatly simplifies the assembly steps and improves the assembly efficiency.
