Description

[0001] The utility model relates to the technical field of connection structures, in particular to a prefabricated connection structure of a photovoltaic component. Background Art

[0002] The prefabricated connection structure of photovoltaic components is a method that allows for faster deployment of photovoltaic systems because it simplifies on-site operation steps and reduces reliance on the skills of on-site workers. This structure includes photovoltaic panels, connectors, junction boxes and other components. Through prefabrication, most of the assembly work can be completed in the factory, and only simple installation is required on site. This method greatly improves the installation efficiency of the photovoltaic system and reduces installation costs.

In view of this, we provide a prefabricated connection structure of photovoltaic components. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0024] like Figure 1-5 As shown, the utility model provides a technical solution: a prefabricated connection structure of photovoltaic components, including a connecting frame 1, the connecting frame 1 is provided with a plurality of connecting frames 1, the inner center of which is slidably connected with a photovoltaic panel 2, and both sides of the inner wall of the connecting frame 1 are fixedly connected with a group of corresponding slide rails 201, the slide rails 201 are located on both sides of the inside of the photovoltaic panel 2, the outer wall on one side of the slide rail 201 is connected through and through with one side of the outer wall of the photovoltaic panel 2, and one side of the inside of the photovoltaic panel 2 is slidably connected with the outer wall on one side of the slide rail 201, the photovoltaic panel 2 is slidably connected to the inner center of the connecting frame 1 through the slide rail 201, one side of the outer wall of the connecting frame 1 is slidably connected with a positioning block 3, and a positioning groove 301 is provided on the side of the outer wall of the connecting frame 1 away from the positioning block 3, and one side of the outer wall of the connecting frame 1 is fitted with one side of the outer wall of the adjacent connecting frame 1 through the positioning block 3.

[0025] After aligning the photovoltaic panel 2 with the slide rails 201 on both sides of the interior of the connecting frame 1, the photovoltaic panel 2 is inserted into the interior of the connecting frame 1. When one side of the outer wall of the photovoltaic panel 2 contacts the inclined surface of one side of the outer wall of the mounting block 203, the photovoltaic panel 2 pushes the mounting block 203 along the strip plate 205 toward the inner side of the connecting frame 1 through the inclined surface opened on the outer wall of the mounting block 203, and the mounting block 203 compresses the mounting spring 204. When the photovoltaic panel 2 slides to the center of the interior of the connecting frame 1, one side of the outer wall of the mounting block 203 loses the thrust from the outer wall of the photovoltaic panel 2, and the mounting spring 204 pushes the mounting block 203 toward the inner center of the connecting frame 1, so that the outer wall of one side of the mounting block 203 and one side of the outer wall of the photovoltaic panel 2 fit each other and conflict with each other, and the photovoltaic panel 2 can be installed in the inner center of the connecting frame 1. When the photovoltaic panel 2 needs to be taken out from the interior of the connecting frame 1, it is only necessary to push the slider 202 away from the photovoltaic panel 2 to disengage the mounting block 203 from the photovoltaic panel 2, and take out the photovoltaic panel 2. When the cam 303 is in contact with the protrusion 304 on one side of the outer wall of the connecting frame 1, the cam 303 is pressed against the protrusion 304 on the inner wall of the connecting frame 1, and the cam 303 is pressed against the protrusion 304 on the inner wall of the connecting frame 1.

[0026] like Figure 1-4 As shown, a slider 202 is slidably connected to one side of the top surface of the connecting frame 1, and the bottom end of the outer wall of the slider 202 passes through one side of the top surface of the connecting frame 1 and is fixedly connected to a mounting block 203, an outer wall of one side of the mounting block 203 and one side of the outer wall of the photovoltaic panel 2 are in contact with and in conflict with each other, a mounting spring 204 is fixedly connected to one side of the interior of the connecting frame 1, and the outer wall of one end of the mounting spring 204 is fixedly connected to one side of the outer wall of the mounting block 203, a plurality of strip plates 205 are fixedly connected to both sides of the inner wall of the connecting frame 1, the strip plates 205 are located on both sides of the interior of the mounting block 203, one side of the outer wall of the strip plates 205 passes through one side of the interior of the mounting block 203, and one side of the interior of the mounting block 203 is slidably connected to one side of the outer wall of the strip plates 205.

[0027] After aligning the photovoltaic panel 2 with the slide rails 201 on both sides of the interior of the connecting frame 1, the photovoltaic panel 2 is inserted into the interior of the connecting frame 1. When one side of the outer wall of the photovoltaic panel 2 contacts the inclined surface of one side of the outer wall of the mounting block 203, the photovoltaic panel 2 pushes the mounting block 203 along the strip plate 205 toward the inner side of the connecting frame 1 through the inclined surface opened on the outer wall of the mounting block 203, and the mounting block 203 compresses the mounting spring 204. When the photovoltaic panel 2 slides to the inner center of the connecting frame 1, one side of the outer wall of the mounting block 203 loses the thrust from the outer wall of the photovoltaic panel 2, and the mounting spring 204 pushes the mounting block 203 toward the inner center of the connecting frame 1. , so that the outer wall of one side of the mounting block 203 and the outer wall of one side of the photovoltaic panel 2 are in contact with each other, the photovoltaic panel 2 can be installed in the center of the connecting frame 1. When the photovoltaic panel 2 needs to be taken out from the inside of the connecting frame 1, it is only necessary to push the slider 202 to the side away from the photovoltaic panel 2 to disengage the mounting block 203 from the photovoltaic panel 2 and take out the photovoltaic panel 2. The mounting block 203 and the slider 202 cooperate with each other to achieve rapid installation and disassembly of the photovoltaic panel 2 in the connecting frame 1, effectively simplify the installation process of the photovoltaic panel 2, improve the installation efficiency, and facilitate the subsequent splicing of the photovoltaic panel 2 through the connecting frame 1.

[0028] like Figure 1 , Figure 2 Figure 4 and Figure 5 As shown, a plug plate 302 is fixedly connected to one side of the outer wall of the connecting frame 1, and one side of the outer wall of the plug plate 302 is connected through the inner side of the adjacent connecting frame 1, a connecting plate 303 is slidably connected to one side of the inner side of the connecting frame 1, and one side of the outer wall of the connecting plate 303 and one side of the inner wall of the plug plate 302 are in contact with and in conflict with each other, a plurality of connecting springs 304 are fixedly connected to one side of the inner side of the connecting frame 1, and the outer wall of one end of the connecting spring 304 is fixedly connected to one side of the outer wall of the connecting plate 303, a pressure plate 305 is slidably connected to one side of the inner side of the connecting frame 1, and one side of the outer wall of the pressure plate 305 is fixedly connected to one side of the outer wall of the connecting plate 303, and the pressure plate 305 and the connecting plate 303 are slidably connected to one side of the inner side of the connecting frame 1 through the connecting spring 304.

[0029] When the cam 302 is in contact with the protrusion 303 on the outer wall of the connecting frame 303, the connecting spring 304 is pushed by the connecting plate 303 so that the connecting plate 303 compresses the connecting spring 304. When the protrusion on the outer wall of the connecting plate 303 corresponds to the groove on the inner side of the connecting plate 302, the connecting spring 304 pushes the connecting plate 303 toward the inner side of the connecting plate 302, and the outer wall side of the connecting plate 303 and the inner wall side of the connecting plate 302 are engaged with each other, and the connecting frames 1 and 1 are fixed to each other, so that the connecting plates 303 and the protrusion 303 are in contact with each other, and the connecting frames 1 are fixed to each other, so that the connecting plates 303 and the protrusion 302 are in contact with each other, and the connecting frames 1 are fixed to each other, so that the connecting plates 303 and the protrusion 302 are in contact with each other, and the connecting frames 1 can be firmly locked together.

[0030] Working principle: After ensuring that the photovoltaic panel 2 is correctly aligned with the two side rails 201 inside the connecting frame 1, the photovoltaic panel 2 is inserted into the inside of the connecting frame 1. This action drives the mounting block 203 to move along the strip plate 205 toward the inside of the connecting frame 1. When the photovoltaic panel 2 reaches the center position of the connecting frame 1, the mounting spring 204 will push the mounting block 203 to move toward the center of the connecting frame 1, causing the outer side of the mounting block 203 and the outer side of the photovoltaic panel 2 to fit tightly and squeeze each other. In this way, the photovoltaic panel 2 is firmly fixed in the center position of the connecting frame 1. Next, the positioning block 3 on the outer wall of one connecting frame 1 is aligned with the preset position on the adjacent connecting frame 1. The positioning grooves 301 are aligned, and then the positioning blocks 3 are inserted into the corresponding positioning grooves 301. After that, the plug plate 302 located on one side of the outer wall of the connecting frame 1 enters the interior of the adjacent connecting frame 1. The plug plate 302 applies force to push the connecting plate 303, so that the connecting plate 303 compresses the connecting spring 304. The reaction force of the connecting spring 304 will push the connecting plate 303 to move toward the plug plate 302, and form an interlocking structure between the outer side of the connecting plate 303 and the inner side of the plug plate 302. Through the close cooperation between the connecting plate 303 and the plug plate 302, the fixation between the two connecting frames 1 becomes firm, and the photovoltaic panels 2 are spliced.
