Description

Photovoltaic module clamp and photovoltaic system

Technical Field

The utility model mainly relates to the field of photovoltaics, in particular to a photovoltaic module clamp and a photovoltaic system.

Background

The solar photovoltaic module fixes the photovoltaic laminated piece containing the solar battery through the section bar, and the section bar has the functions of enhancing the mechanical strength of the photovoltaic module, sealing the edge of the photovoltaic laminated piece and fixing the photovoltaic laminated piece on the purline, so that the solar photovoltaic module, the photovoltaic module for short, or the module is formed. In the actual production and installation process, the photovoltaic module with the profile is further required to be connected and fixed through the photovoltaic module clamp, namely the photovoltaic module clamp is used for fixing the profile to complete the splicing and fixing of the photovoltaic module.

The existing photovoltaic module clamp for fixing the profile with the side grooves is required to be respectively embedded into the side grooves of the profile on the left side and the right side, and because the width dimension of the clamp is larger than the distance between photovoltaic modules, when the photovoltaic array middle profile casting die is disassembled, even if a fastener between the module and the photovoltaic module clamp is unscrewed, the clamp is not easy to take out from the upper part, and only the photovoltaic module clamp can be slid out along the frame direction. The gaps between the actual photovoltaic modules are not uniform, and even the problem of deformation after bearing exists, so that the photovoltaic module clamp can slide out along the frame direction, which is inconvenient or even impossible to complete, namely the problem of difficult disassembly and replacement exists.

Meanwhile, as the demand of the photovoltaic module in the market is continuously improved, the large-size photovoltaic module is popular gradually, however, the installation of the existing photovoltaic module clamp requires operators to finish the assembly of the photovoltaic modules at the two sides of the photovoltaic module clamp, and then the photovoltaic module clamp and bolts are screwed. This results in insufficient arm deployment, difficulty in tightening, and even some out-of-specification handling of the kneeling of the photovoltaic module when the ordinary installer wants to tighten the bolts or photovoltaic module clamps away from his side, increasing the risk of hidden cracking of the module.

Referring to fig. 2-4 in combination, the securing portion 110 is adapted to provide a fastener 20 during actual installation and use of the photovoltaic module clip 100, the fastener 20 securing the photovoltaic module clip 100 to the purlin 40. The first lateral extension 120 is disposed on one side of the fixing portion 110, in this embodiment, the left side as shown in fig. 4, and the second lateral extension 130 is disposed on the other side of the fixing portion 110, i.e., the right side as shown in fig. 4. Referring to fig. 4, the photovoltaic module fixture 100 provided in this embodiment is suitable for being installed between two adjacent photovoltaic modules, the profile 10 is installed at the edge of the photovoltaic laminate 50 in both photovoltaic modules, and the photovoltaic laminate 50 is partially disposed in the accommodating groove of the profile 10. For convenience of understanding, the two photovoltaic modules are respectively named as a first photovoltaic module and a second photovoltaic module, the profiles installed at the edges of the two photovoltaic modules are respectively a first profile 10a and a second profile 10b, and then the first lateral extension 120 of the photovoltaic module fixture 100 is suitable for being matched with the top surface of the bearing part 11a of the first profile 10a of the first photovoltaic module, and the second lateral extension 130 is suitable for being matched with the top surface of the bearing part 11b of the second profile 10b of the second photovoltaic module. The first longitudinal extension 140 extends from the side of the photovoltaic module fixture 100 (the same side as the first lateral extension 120, i.e. the left side as shown in fig. 4) in a direction away from the first lateral extension 120, and the bottom of the first longitudinal extension 140 has a first groove 141 (as shown in fig. 2-3) for mating with the protrusion 13a of the first profile 10 a.

Further, in this embodiment, the first and second longitudinal extending portions 140 and 150 are spaced apart and elastically deformable, so that the distance between them is reduced to be less than or equal to the installation distance between the first and second profiles 10a and 10 b. It is understood that the spacing of the first and second longitudinal extensions 140, 150 herein refers to the distance between the outer sides thereof. Based on the arrangement, the photovoltaic module clamp provided by the embodiment does not need to move the photovoltaic modules at two sides or slide out of the side grooves when being disassembled, and can be directly taken out upwards. In the process of taking out, the first longitudinal extension part 140 and the second longitudinal extension part 150 deform towards the position close to each other, the distance between the two parts is reduced to be smaller than or equal to the installation distance D between the two adjacent sections, the two sections can be directly taken out, and the deformation is recovered after taking out.

The arrangement can enable the photovoltaic module clamp 100 to play a fixing effect on the first section bar 10a and the second section bar 10b in the horizontal direction, the first lateral extension part 120 and the second lateral extension part 130 are not relied on to extrude and fix the bearing parts 11a and 11b in the vertical direction, and the possibility of the pressed damage of the photovoltaic laminated board is reduced.

To further enhance this effect, fig. 2-4 show a preferred embodiment of the present application, in which when the photovoltaic module fixture 100 and the first profile 10a are installed, i.e. the first groove 141 abuts against the protrusion 13a of the first profile 10a, a gap H1 is formed between the first lateral extension 120 and the top surface of the carrying portion 11a of the first profile 10 a; similarly, when the photovoltaic module fixture 100 and the second profile 10b are mounted, i.e. the second groove 151 abuts against the protrusion 13b of the second profile 10b, a gap H2 is formed between the second lateral extension 130 and the top surface of the bearing portion 11b of the second profile 10b, and the width of H1 is the same as the width of H2 in this embodiment. The gap is arranged, so that the photovoltaic module clamp can be prevented from applying pressure to the profile in the longitudinal direction, and the lamination piece in the photovoltaic module is prevented from being extruded. Thus, the lateral extensions 120, 130 cooperate with the top surface of the bearing portion 11a or 11b of the profile 10a or 10b, either in contact or with a certain clearance.
