Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic panel technology, specifically to a highly stable modular solar photovoltaic panel. Background Technology

[0002] A solar photovoltaic (PV) panel is a device that converts solar radiation into electrical energy. It mainly consists of solar cell modules, a support structure, and a surface covering layer. Its core working principle is based on the photovoltaic effect: when sunlight shines on the PV panel, the energy of the light activates electrons within the panel, releasing them from their atomic orbitals and causing them to flow within the panel, forming an electric current. Because multiple solar PV panels are typically installed simultaneously, modular PV panels offer faster installation.

[0003] The existing technology has the following shortcomings: The existing technology, in the publication number CN213693592U, "a split splicing solar photovoltaic panel", "includes a mounting plate, a mounting frame disposed on the upper end of the mounting plate, a first connecting member disposed on both sides of the mounting frame, a second connecting member disposed between the adjacent mounting frames, a support strip disposed between the mounting frame and the mounting plate, mounting grooves uniformly disposed on the mounting frame, and a solar photovoltaic panel disposed between the mounting grooves".

[0004] The above structure supports the mounting frame with support bars, which avoids damage to the mounting plate by the mounting frame. In addition, it is convenient to fix the outer perimeter of the mounting frame through the first connector. However, this structure only adopts a single-group unidirectional splicing method and does not make any improvements to the external splicing structure. Since photovoltaic panels are often installed in batches, the inability to establish a connection between adjacent photovoltaic panels will result in poor splicing flexibility and overall installation stability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a highly stable modular solar photovoltaic panel, solving the problems of the inability to connect adjacent photovoltaic panels and the poor flexibility and stability of splicing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a highly stable split-type splicing solar photovoltaic panel, comprising a splicing frame main body, a photovoltaic panel, and a secondary splicing frame, wherein the photovoltaic panel is disposed on the upper end of the splicing frame main body, the secondary splicing frame is disposed on the side end of the splicing frame main body, an installation node is provided at the bottom of the splicing frame main body, and a support rib is connected to the side end of the installation node.

[0007] The splicing frame body has a fitting end on one side and an insertion end on the other side. A displacement locking frame is also provided on one side of the splicing frame body, and a connecting shaft is provided on the side of the displacement locking frame.

[0008] The splicing frame body also includes a transverse slide and a limiting frame. The transverse slide is opened at one end of the splicing frame body near the displacement locking frame, and the limiting frame is fixedly connected to the end of the splicing frame body away from the transverse slide.

[0009] The secondary splicing frame has the same overall structure as the main splicing frame, but the positions of the mating end, insertion end, limiting frame, and displacement locking frame are reversed.

[0010] The fitting end also includes a one-way limiting groove, a conical groove, and an electrical connection groove. The one-way limiting groove is formed inside the fitting end, the conical groove is formed on the inner end face of the one-way limiting groove, and the electrical connection groove is formed on the same side end face inside the one-way limiting groove.

[0011] The insertion end also includes a limiting strip, a one-way cone block, and a conductive spring. The limiting strip is fixedly connected to both sides of the insertion end, the one-way cone block is fixedly connected to the side end of the insertion end, and the conductive spring is fixedly installed on the same side end face of the insertion end.

[0012] In some embodiments, the conical grooves correspond to the positions of the unidirectional conical blocks, are the same in number, and have their internal acute angles facing opposite directions.

[0013] In some embodiments, the displacement locking frame further includes a rack, a drive gear, a handle, and a slider. The rack is fixedly connected to the lower inner side of the displacement locking frame, and the drive gear meshes with the tooth groove of the rack and is movably connected to the splicing frame body through a connecting shaft.

[0014] In some embodiments, the handle is fixedly connected to the middle of the outer side of the drive gear, and the slider is fixedly connected to the end face of the displacement locking frame facing the splicing frame body and inserted into the transverse slide groove.

[0015] In some embodiments, the electrical connection slot and the conductive spring are positioned opposite each other, and extend inward from the insertion end to the negative terminal respectively. The connection method between the splicing frame main body and the secondary splicing frame is that the positive terminals are connected to each other and the negative terminals are connected to each other.

[0016] In some embodiments, the displacement locking frame has an irregular strip-shaped structure, with a hollow opening in the middle of one side near the limiting frame, and the shape of the opening is the same as that of the limiting frame.

[0017] Compared with existing technologies, this invention provides a highly stable modular solar photovoltaic panel:

[0018] A highly stable modular solar photovoltaic panel is designed with a mating end, an insertion end, a displacement locking frame, a rack, a drive gear, a one-way limiting groove, and a conical groove. In use, the operator places the main body of the splicing frame and the secondary splicing frame on the same horizontal plane, with the insertion end facing the mating end. Then, the operator inserts the limiting strip of the insertion end into the one-way limiting groove from the outside of the mating end. During this process, the one-way cone is embedded in the conical groove, while the conductive spring slides continuously until the positive and negative poles at the top and bottom contacts the electrical connection groove. At this point, the main body of the splicing frame and the secondary splicing frame are connected in parallel. The operator then holds the handle and rotates it, causing the rack to move and simultaneously driving the displacement locking frame. The slider on the side of the displacement locking frame slides in the transverse groove until the clamping structure on the side of the displacement locking frame clamps onto the outside of the limiting frame. At this point, the main body of the splicing frame and the secondary splicing frame are locked together.

[0019] The above settings and procedures can enable this structure to achieve the following beneficial effects:

[0020] By combining the fitting end, insertion end, conical groove, and unidirectional conical block, the solar photovoltaic panel can be quickly spliced ​​and disassembled through modular design, and the insertion direction is limited so that the photovoltaic panel is not easy to come out from the side after the connection is completed. By combining the displacement locking frame, rack and pinion, and limit frame, this structure can be spliced ​​in two different positions, longitudinal and transverse, compared with the existing unidirectional splicing structure, which greatly increases the stability of the overall structure while maintaining splicing flexibility.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] In this implementation plan: A highly stable split-type solar photovoltaic panel includes a splicing frame body 1, a photovoltaic panel 2, and a secondary splicing frame 3. The photovoltaic panel 2 is disposed on the upper end of the splicing frame body 1, and the secondary splicing frame 3 is disposed on the side end of the splicing frame body 1. An installation node 5 is provided at the bottom of the splicing frame body 1, and a support rib 6 is connected to the side end of the installation node 5.

[0033] The splicing frame body 1 has a fitting end 4 on one side and an insertion end 7 on the other side. The splicing frame body 1 also has a displacement locking frame 8 on one side and a connecting shaft 9 on the side of the displacement locking frame 8.

[0034] The splicing frame body 1 also includes a transverse slide 101 and a limiting frame 102. The transverse slide 101 is opened at one end of the splicing frame body 1 near the displacement locking frame 8, and the limiting frame 102 is fixedly connected to the end of the splicing frame body 1 away from the transverse slide 101.

[0035] In this embodiment, the structure of the secondary splicing frame 3 is exactly the same as that of the splicing frame body 1, but the positions of the fitting end 4, the insertion end 7, the limiting frame 102, and the displacement locking frame 8 are reversed; the fitting end 4 also includes a one-way limiting groove 401, a conical groove 402, and an electrical connection groove 403. The one-way limiting groove 401 is opened inside the fitting end 4, the conical groove 402 is opened on the inner end face of the one-way limiting groove 401, and the electrical connection groove 403 is opened on the same side end face inside the one-way limiting groove 401.

[0036] Specifically, such as Figure 2 Figure 3 and Figure 6 As shown, the mating end 4 is recessed inward as a whole, and the connection of the insertion end 7 is accommodated by the one-way limiting groove 401 and the strip grooves opened on the upper and lower sides. The insertion end 7 can only be connected by one-way insertion.

[0037] In this embodiment, the insertion end 7 also includes a limiting strip 701, a one-way cone block 702, and a conductive spring 703. The limiting strip 701 is fixedly connected to both sides of the insertion end 7, the one-way cone block 702 is fixedly connected to the side end of the insertion end 7, and the conductive spring 703 is fixedly installed on the same side end face of the insertion end 7. The conical groove 402 corresponds to the one-way cone block 702 in position, has the same number, and the internal acute angles face opposite directions.

[0038] Specifically, such as Figure 1 Figure 4 and Figure 7 As shown, after the unidirectional cone block 702 establishes a connection between the insertion end 7 and the mating end 4, it meshes with the cone groove 402. At this time, the insertion end 7 cannot move in the opposite direction and can only be dislodged by continuous sliding.

[0039] In this embodiment, the displacement locking frame 8 also includes a rack 801, a drive gear 802, a handle 803, and a slider 804. The rack 801 is fixedly connected to the lower inner side of the displacement locking frame 8. The drive gear 802 meshes with the tooth groove of the rack 801 and is movably connected to the splicing frame body 1 through the connecting shaft 9. The handle 803 is fixedly connected to the middle outer side of the drive gear 802. The slider 804 is fixedly connected to the end face of the displacement locking frame 8 facing the splicing frame body 1 and is inserted into the transverse slide groove 101.

[0040] Specifically, such as Figure 5As shown, when the grip 803 rotates, the drive gear 802 rotates synchronously according to the rotation direction of the grip 803, while the rack 801 changes its movement direction according to the rotation direction of the grip 803, until the clamping structure at the side end of the displacement locking frame 8 clamps onto both sides of the limiting frame 102 and completes the locking.

[0041] In this embodiment, the electrical connection groove 403 and the conductive spring 703 are positioned opposite each other, and extend inward from the insertion end 7 to the negative end respectively. The connection method between the splicing frame body 1 and the secondary splicing frame 3 is that the positive ends are connected to the positive ends and the negative ends are connected to the negative ends. The displacement locking frame 8 has an irregular strip structure, and a hollow opening is provided in the middle of the side near the limiting frame 102. The shape of the opening is the same as that of the limiting frame 102.

[0042] The working principle and usage process of this invention are as follows: When using this structure, the operator places the splicing frame main body 1 and the secondary splicing frame 3 on the same horizontal plane, and makes the insertion end 7 opposite to the fitting end 4. Then, the limiting strip 701 of the insertion end 7 is inserted into the one-way limiting groove 401 from the outside of the fitting end 4. During this process, the one-way cone block 702 is embedded in the cone groove 402, and the conductive spring 703 slides continuously until the upper and lower positive and negative poles respectively contact the power connection groove 403. At this time, the splicing frame main body 1 and the secondary splicing frame 3 are connected in parallel. Then, the operator holds the handle 803 and rotates it, so that the rack 801 is driven and the displacement locking frame 8 is driven at the same time. The slider 804 on the side of the displacement locking frame 8 slides in the transverse sliding groove 101 until the clamping structure on the side of the displacement locking frame 8 is clamped on the outside of the limiting frame 102. At this time, the splicing frame main body 1 and the secondary splicing frame 3 are locked.

[0043] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
