Description

Technical Field

[0001] The present invention relates to the technical field of solar photovoltaic panels, and particularly to a split and spliced solar photovoltaic panel with strong stability. Background Art

[0002] A solar photovoltaic panel is a device that converts solar radiant energy into electrical energy, mainly composed of solar cell modules, brackets, and a covering layer on the surface of the panel. Its core working principle is based on the photovoltaic effect, that is, when sunlight irradiates the photovoltaic panel, the energy of the light will activate the electrons in the photovoltaic panel, causing them to be released from the atomic orbit and flow within the photovoltaic panel to form an electric current. Since solar photovoltaic panels are usually installed in multiple groups at the same time, spliced photovoltaic panels are more convenient to use.

[0003] The prior art has the following deficiencies: In the "split and spliced solar photovoltaic panel" with the publication number CN213693592U in the prior art, it "includes a mounting plate, a mounting frame provided at the upper end of the mounting plate, first connecting members provided on both sides of the mounting frame, second connecting members provided between adjacent mounting frames, support bars provided between the mounting frame and the mounting plate, mounting grooves uniformly provided on the mounting frame, and solar photovoltaic panels provided between the mounting grooves".

[0004] The above structure supports the mounting frame through the support bars, avoiding damage to the mounting plate by the mounting frame. In addition, it is convenient to fix the outer periphery of the mounting frame through the first connecting members. However, this structure only adopts a single-group and one-way splicing method and does not improve the external splicing structure. Since photovoltaic panels are often installed in batches, the inability to establish connections between adjacent photovoltaic panels will result in poor splicing flexibility and overall installation stability. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a split and spliced solar photovoltaic panel with strong stability, solving the problems of the inability to establish connections between adjacent photovoltaic panels and poor splicing flexibility and stability existing nowadays.

[0006] To achieve the above object, the present invention provides the following technical solution: A split and spliced solar photovoltaic panel with strong stability, including a splicing frame main body, a photovoltaic panel, and a secondary splicing frame. The photovoltaic panel is arranged at the upper end of the splicing frame main body, the secondary splicing frame is arranged at the side end of the splicing frame main body, mounting nodes are arranged at the bottom of the splicing frame main body, and support ribs are connected to the side ends of the mounting nodes.

[0007] A fitting end is arranged at the side end of the splicing frame main body, an insertion end is arranged on the other end face of the splicing frame main body, a displacement locking frame is also arranged on one side of the splicing frame main body, and a connecting shaft is arranged on the side of the displacement locking frame.

[0008] The splicing frame body further includes a transverse chute and a limiting frame. The transverse chute is opened at one end of the splicing frame body close to the displacement locking frame, and the limiting frame is fixedly connected to the end of the splicing frame body far from the transverse chute.

[0009] In some embodiments, the structure of the secondary splicing frame as a whole is exactly the same as that of the splicing frame body, but the positions of the fitting end, the insertion end, the limiting frame and the displacement locking frame are opposite.

[0010] In some embodiments, the fitting end further includes a one-way limiting groove, a tapered groove, and an electrical connection groove. The one-way limiting groove is opened on the inner side of the fitting end, the tapered groove is opened on the inner end face of the one-way limiting groove, and the electrical connection groove is opened on the same side end face inside the one-way limiting groove.

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

[0012] In some embodiments, the tapered groove and the one-way tapered block are in corresponding positions, have the same number, and the internal acute angles face opposite directions.

[0013] In some embodiments, the displacement locking frame further includes a rack, a driving gear, a grip, and a slider. The rack is fixedly connected to the lower end inside the displacement locking frame. The driving 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 grip is fixedly connected to the middle of the outer side of the driving gear. The slider is fixedly connected to the end face of the displacement locking frame facing the splicing frame body and is inserted into the transverse chute.

[0015] In some embodiments, the positions of the electrical connection groove and the conductive spring piece are opposite, and the extensions from the insertion side of the insertion end inward are from positive to negative respectively. The connection method between the splicing frame body and the secondary splicing frame is specifically that the positive poles are connected to each other and the negative poles are connected to each other.

[0016] In some embodiments, the displacement locking frame as a whole has an irregular strip structure. There is a hollow opening in the middle of the side close to the limiting frame, and the shape of this opening is the same as that of the limiting frame.

[0017] Compared with the prior art, the present invention provides a split-splicing type solar photovoltaic panel with strong stability: A split and spliced solar photovoltaic panel with strong stability. By setting a fitting end, an insertion end, a displacement locking frame, a rack, a driving gear, a one-way limiting groove, and a conical groove, when using this structure, the operator places the main splicing frame and the secondary splicing frame on the same horizontal plane, makes the insertion end face the fitting end, and then inserts the limiting strip of the insertion end into the one-way limiting groove from the outside of the fitting end. During this process, the one-way cone block is embedded in the conical groove, and the conductive spring piece slides continuously until the positive and negative electrodes at the upper and lower ends are respectively in contact with the power connection slots. At this time, the main splicing frame and the secondary splicing frame are connected in parallel. Then the operator holds the handle and rotates it, driving the rack while driving the displacement locking frame. The slider at the side end of the displacement locking frame slides in the horizontal sliding groove until the clamping structure at the side end of the displacement locking frame clamps outside the limiting frame. At this time, the main splicing frame and the secondary splicing frame are locked; Through the above settings and processes, the following beneficial effects can be achieved for this structure: Through the cooperation of the fitting end, the insertion end, the conical groove, and the one-way cone block, the solar photovoltaic panel can be quickly spliced and disassembled through modular design, and the insertion direction can be limited, making it difficult for the photovoltaic panel to come out laterally after connection. Through the cooperation of the displacement locking frame, the rack, and the limiting frame, compared with the existing one-way splicing structure, this structure can be spliced in two different positions, longitudinally and horizontally, greatly increasing the stability of the overall structure while maintaining the splicing flexibility.

[0027] Specifically, as Figure 2 Figure 3 and Figure 6 shown, the fitting end 4 is recessed inward as a whole, and the connection of the insertion end 7 is accommodated through the one-way limiting groove 401 and the strip-shaped grooves opened on the upper and lower sides, and the insertion end 7 can only be connected in a one-way insertion manner.
