Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel installation technology, specifically to a photovoltaic module horizontal mounting connection device and a photovoltaic module having the same. Background Technology

[0002] During photovoltaic installation, photovoltaic panels need to be installed and fixed onto inclined beam square tubes. A common approach is to use M-purlins, which are waterproof, load-bearing, and also function as purlins. Currently, the connection between photovoltaic panels and inclined beam square tubes generally uses M-purlins as intermediaries. Both the photovoltaic panels and the inclined beam square tubes are connected to the M-purlins, thus achieving the connection between the photovoltaic panels and the inclined beam square tubes.

[0003] In existing technology, M-purlins have multiple horizontally arranged elongated holes on their sides as mounting holes. These holes need to connect with the connecting holes on the L-shaped adapter using bolts or other fasteners to fix the M-purlins to the inclined beam square tube via the L-shaped connector. They also need to connect with the connecting holes on the U-shaped connector using bolts or other fasteners to connect and fix adjacent M-purlins via the U-shaped connector. However, because the installation position cannot be guaranteed to be completely flat, it is impossible to ensure that the connecting holes on both the L-shaped adapter and the U-shaped connector are flush with the mounting holes on the M-purlins. This leads to misalignment of the holes during installation of the L-shaped adapter, causing inconvenience in installation. Furthermore, internal stress exists in the L-shaped adapter after installation, affecting the stability of the photovoltaic module. Utility Model Content

[0004] In view of this, the present invention provides a photovoltaic module horizontal mounting connection device and a photovoltaic module having the same, to solve the problem in the prior art that the holes of the horizontal mounting M-purlins of photovoltaic modules may not be aligned when they are installed with the L-shaped adapter.

[0005] In a first aspect, this utility model provides a horizontal mounting connection device for photovoltaic modules, comprising:

[0006] The purlin body section has an M-shaped cross section perpendicular to its length direction. The side of the purlin body section is provided with mounting holes, which are elongated holes with their length direction perpendicular to the length direction of the purlin body section.

[0007] The purlin contraction section is located at one end of the purlin body section along its length. The shape of the purlin contraction section is adapted to the shape of the purlin body section, and the width of the purlin contraction section is smaller than the width of the purlin body section. A mating hole is provided on the side of the purlin contraction section.

[0008] When installing photovoltaic (PV) modules on axial mounting connections, multiple axial mounting connections are sequentially connected along their length. When assembling adjacent axial mounting connections, the purlin body section of the preceding axial mounting connection is stacked over the purlin contraction section of the following axial mounting connection, and secured with bolts or other fasteners passing through the mounting holes and mating holes. When installing axial mounting connections on the inclined beam square tube of the PV module, one side of the L-shaped adapter plate is fixed to the inclined beam square tube, and the other side is secured by bolts or other fasteners passing through and mating with the mounting holes on the purlin body section. Because the mounting holes are elongated holes perpendicular to the length of the purlin body section, a certain degree of installation error is allowed in the vertical direction, ensuring that even if the installation position of the purlin body section is uneven, it can still be connected to the L-shaped adapter plate. When adjacent photovoltaic (PV) module horizontal mounting connection devices are stacked and overlapped, the different widths of the purlin body section and the purlin contraction section allow for a close fit between the purlin body section and the purlin contraction section on different PV module horizontal mounting connection devices in the vertical direction, ensuring the stability of the connection between adjacent PV module horizontal mounting connection devices. By setting vertically arranged elongated holes as mounting holes for installation with L-shaped adapter plates, and by using purlin contraction sections as connecting parts between adjacent PV module horizontal mounting connection devices, a margin for installation error is allowed in the vertical direction during installation, ensuring smooth installation between adjacent PV module horizontal mounting connection devices and between the purlin body section and the L-shaped adapter plate.

[0009] In one optional embodiment, the purlin contraction section and the purlin body section are connected by a transition step. By setting the transition step, when adjacent photovoltaic module horizontal mounting connection devices are installed together, the mounting hole and mating hole are precisely aligned when the end of the purlin body section of the preceding photovoltaic module horizontal mounting connection device directly abuts against the transition step on the following photovoltaic module horizontal mounting connection device. This eliminates the need for hole alignment steps during the installation of the photovoltaic module horizontal mounting connection device, facilitating installation and construction.

[0010] In one alternative embodiment, both the side of the purlin body section and the side of the purlin contraction section are perpendicular to the transition step.

[0011] In one alternative embodiment, the mating hole is an elongated hole, with its length direction parallel to the length direction of the purlin contraction section; or, the mating hole is a circular hole.

[0012] In one optional embodiment, mounting plates are provided at both protrusions on the top surface of the purlin body section, and mating plates are provided at both protrusions on the top surface of the purlin contraction section. The width of the mating plates is smaller than the width of the mounting plates, and both the mounting plates and the mating plates extend along the length of the purlin body section. By providing the mounting plates and mating plates, when the purlin body section and the purlin contraction section are stacked, their tops make room for each other, preventing gaps between the purlin body section and the purlin contraction section on the horizontal mounting connection device of two photovoltaic modules from being restricted, thus ensuring the stability of the fit between adjacent purlin body sections and purlin contraction sections, and preventing water leakage at the connection of the horizontal mounting connection device of the photovoltaic modules.

[0013] In one alternative implementation, both the mounting plate and the mating plate are arranged horizontally.

[0014] In one optional embodiment, each recessed area on the bottom surface of the purlin body section has a drainage horizontal plate, and each recessed area on the bottom surface of the purlin contraction section has a drainage mating plate, with the top surfaces of the drainage horizontal plates and drainage mating plates flush. When the photovoltaic module horizontal mounting connection devices are installed sequentially, the upstream photovoltaic module horizontal mounting connection devices are stacked on top of the downstream photovoltaic module horizontal mounting connection devices. This allows water to flow smoothly downstream between the photovoltaic module horizontal mounting connection devices, preventing leakage at the connection points of adjacent photovoltaic module horizontal mounting connection devices and improving the overall drainage efficiency of the photovoltaic modules.

[0015] In one alternative implementation, the width of the drainage mating plate is greater than the width of the drainage cross plate.

[0016] In one optional embodiment, a folded edge is provided at the bottom of the side of the purlin body section. The folded edge is folded towards the inside or outside of the purlin body section to increase the stress-bearing area between the purlin body section and the bottom structure, thereby avoiding deformation of the bottom of the purlin body section due to stress concentration when subjected to external force and improving the long-term stability of the photovoltaic module horizontal installation connection device.

[0017] Secondly, this utility model also provides a photovoltaic module having the horizontal mounting connection device for photovoltaic modules described in this utility model. Since the photovoltaic module includes the horizontal mounting connection device for photovoltaic modules, it has the same effect as the horizontal mounting connection device for photovoltaic modules, and will not be described again here.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0030] According to an embodiment of the present invention, a photovoltaic module horizontal mounting connection device is provided, including a purlin body section 1 and a purlin contraction section 2.

[0031] The purlin body section 1 has an M-shaped cross-section perpendicular to its length direction. A mounting hole 3 is provided on the side of the purlin body section 1; the mounting hole 3 is an elongated hole, and its length direction is perpendicular to the length direction of the purlin body section 1. A purlin contraction section 2 is located at one end of the purlin body section 1 along its length direction. The purlin contraction section 2 is an M-shaped section that matches the shape of the purlin body section 1, and its width is less than the width of the purlin body section 1. A mating hole 4 is provided on the side of the purlin contraction section 2.

[0032] When installing a horizontal photovoltaic module mounting connection device on a photovoltaic module, multiple horizontal photovoltaic module mounting connection devices are sequentially connected along the length direction. When assembling adjacent horizontal photovoltaic module mounting connection devices, the purlin body section of the preceding horizontal photovoltaic module mounting connection device is stacked and covered onto the purlin contraction section 2 of the following horizontal photovoltaic module mounting connection device, and then fixed using bolts or other fasteners passing through the mounting holes 3 and mating holes 4. When installing the horizontal photovoltaic module mounting connection device on the inclined beam square tube 11 of the photovoltaic module, one side of the L-shaped adapter plate 10 is fixed to the inclined beam square tube 11, and the other side is fixed by bolts or other fasteners passing through and mating with the mounting holes 3 on the purlin body section 1. Since the mounting hole 3 is a long hole perpendicular to the length direction of the purlin body section 1, a certain degree of installation error distance is reserved in the vertical direction, ensuring that even if the installation position of the purlin body section 1 is uneven, it can still be connected to the L-shaped adapter plate 10. When adjacent photovoltaic module horizontal mounting connection devices are stacked and overlapped for installation, the different widths of the purlin body section 1 and the purlin contraction section 2 allow for close stacking of the purlin body section 1 and the purlin contraction section 2 on different photovoltaic module horizontal mounting connection devices in the vertical direction, ensuring the stability of the connection between adjacent photovoltaic module horizontal mounting connection devices. By setting vertically arranged elongated holes as mounting holes 3 to mate with the L-shaped adapter plate 10, and by setting the purlin contraction section 2 as the connecting part of adjacent photovoltaic module horizontal mounting connection devices, a margin for installation error exists in the vertical direction during the installation of the photovoltaic module horizontal mounting connection devices, ensuring smooth installation between adjacent photovoltaic module horizontal mounting connection devices and between the purlin body section 1 and the L-shaped adapter plate 10.

[0033] In one embodiment, the purlin contraction section 2 and the purlin body section 1 are connected by a transition step. By providing the transition step, when adjacent photovoltaic module horizontal mounting connection devices are installed together, the mounting hole 3 and the mating hole 4 are precisely aligned when the end of the purlin body section 1 of the preceding photovoltaic module horizontal mounting connection device directly abuts against the transition step on the following photovoltaic module horizontal mounting connection device. This eliminates the need for hole alignment steps during photovoltaic module horizontal mounting connection device installation, facilitating installation. In this embodiment, the side surfaces of both the purlin body section 1 and the purlin contraction section 2 are perpendicular to the transition step.

[0034] In this embodiment, the mating hole 4 is a round hole. In some other embodiments, the mating hole 4 is an elongated hole, with its length parallel to the length of the purlin contraction section 2. This allows for greater positional tolerance when the mating hole 4 is aligned with the mounting hole 3. After stacking, the two photovoltaic module horizontal mounting connection devices can be quickly and securely connected by bolts or other fasteners passing through the mounting hole 3 and the mating hole 4, facilitating installation.

[0035] In one embodiment, mounting plates 5 are provided at both protrusions on the top surface of the purlin body section 1, and mating plates 6 are provided at both protrusions on the top surface of the purlin contraction section 2. The width of the mating plates 6 is smaller than the width of the mounting plates 5. Both the mounting plates 5 and the mating plates 6 extend along the length of the purlin body section. By providing the mounting plates 5 and the mating plates 6, when the purlin body section 1 and the purlin contraction section 2 are stacked, their tops make room for each other, preventing gaps between the purlin body section 1 and the purlin contraction section 2 on the two photovoltaic module horizontal mounting connection devices, ensuring the stability of the mating between adjacent purlin body sections 1 and purlin contraction sections 2, and preventing water leakage at the connection of the photovoltaic module horizontal mounting connection devices. Specifically, the mounting plates 5 and the mating plates 6 are both arranged horizontally. In some other embodiments, the mounting plates 5 and the mating plates 6 may also have a certain tilt angle.

[0036] In one embodiment, each recessed area on the bottom surface of the purlin body section 1 has a drainage horizontal plate 7, and each recessed area on the bottom surface of the purlin contraction section 2 has a drainage mating plate 8. The top surfaces of the drainage horizontal plate 7 and the drainage mating plate 8 are flush. The drainage horizontal plate 7 and the drainage mating plate 8 form a drainage channel for drainage. When the photovoltaic module horizontal mounting connection devices are installed sequentially, the upstream photovoltaic module horizontal mounting connection devices are stacked on top of the downstream photovoltaic module horizontal mounting connection devices, so that the water flow can flow downstream between the photovoltaic module horizontal mounting connection devices, which can prevent water leakage at the connection of adjacent photovoltaic module horizontal mounting connection devices and improve the overall drainage efficiency of the photovoltaic modules. The width of the drainage mating plate 8 is greater than the width of the drainage horizontal plate 7 to facilitate the stacking installation between two adjacent photovoltaic module horizontal mounting connection devices.

[0037] In one embodiment, such as Figure 7 As shown, a folded edge 9 is provided at the bottom of the side of the purlin body section 1. The folded edge 9 is folded towards the inside or outside of the purlin body section 1 to increase the stress-bearing area between the purlin body section 1 and the bottom structure, so as to avoid deformation caused by stress concentration at the bottom of the purlin body section 1 when subjected to external force, and improve the stability of the photovoltaic module horizontal installation connection device in the long term.

[0038] Secondly, this utility model also provides a photovoltaic module having the horizontal mounting connection device for photovoltaic modules described in this utility model. Because the photovoltaic module includes the horizontal mounting connection device, it has the same effect as the horizontal mounting connection device for photovoltaic modules. In the photovoltaic module, the horizontal mounting connection devices are arranged sequentially along the length direction. During installation, as... Figure 8 As shown, the purlin body section 1 is aligned with the through hole on the L-shaped adapter plate 10 via a vertically arranged elongated hole serving as the mounting hole 3, and then fixed with bolts. The other side of the L-shaped adapter plate 10 is fixedly installed on the inclined beam square tube 11. Between adjacent photovoltaic module horizontal mounting connection devices in the length direction, the end of the purlin body section 1 of the previous photovoltaic module horizontal mounting connection device is stacked on top of the purlin contraction section 2 of the subsequent photovoltaic module horizontal mounting connection device. After being aligned with the mounting hole 3 and the mating hole 4, they are fixed with bolts to connect the photovoltaic module horizontal mounting connection devices in the length direction. By setting the vertically arranged elongated hole as the mounting hole 3 to mate with the L-shaped adapter plate 10 for installation, and by setting the purlin contraction section 2 as the connection part of the adjacent photovoltaic module horizontal mounting connection devices, the photovoltaic module horizontal mounting connection devices can have an installation error margin in the vertical direction during installation, ensuring that the adjacent photovoltaic module horizontal mounting connection devices and the purlin body section 1 and the L-shaped adapter plate 10 can be installed smoothly.
