Description

  The present invention relates to a holding structure that can be stacked in multiple stages in a state where solar cell modules are held in a horizontal state.

  2. Description of the Related Art Conventionally, a modular plug-in system that securely stores photovoltaic modules (hereinafter referred to as solar cell modules) stacked horizontally is known (see Patent Document 1).

  In this insertion system, solar cell modules are horizontally stacked and packaged using a molded product member 110 shown in FIG.

  Briefly, the molded product member 110 shown in FIG. 14 is fitted with a columnar column 111 formed in a cylindrical shape and a corner portion of a solar cell module extending horizontally from the peripheral side wall of the columnar column 111 from the side. A holding portion 112 that is open in the horizontal direction for holding and holding, and the upper end surface and the lower end surface of the support column portion 111 are sequentially fitted with different molded product members 111 that are arranged adjacent to each other in the vertical direction.

JP 2006-32978 A

  By the way, in the insertion system having the above configuration, since the molded product member 110 is only fitted in each corner portion of the solar cell module, the solar cell modules stacked in multiple stages using the molded product member 110 are The structure is supported only by the part.

  The solar cell module having a frameless structure has a laminated glass structure of two sheets, and the outer dimensions of the solar cell module are 1400 mm in length and 1000 mm in width in the case of a large size. And when such a large-sized solar cell module is supported only by the corner parts of four corners, there exists a problem that the whole load will be applied to a center part and a center part will bend.

  Therefore, normally, in a state where each corner portion of the solar cell module is held by the molded product member 110 as described above, the buffer member in which the edge on the long side of the solar cell module is formed in a U-shaped cross section. By sandwiching and holding, the bending of the central part is improved even a little.

  However, even though a buffer member is provided, it only holds the edge of the solar cell module, and the center is not yet held. The light receiving surface glass and the back glass may be damaged due to repeated bending fluctuations. In some cases, the light receiving surface glass and the back glass may be damaged by contact or collision between the upper and lower solar cell modules. There was a problem that there was.

  The present invention was devised to solve such problems, and its purpose is to transport the solar cell module by supporting the central portion of the solar cell module when it is stacked in multiple stages in a horizontal state. An object of the present invention is to provide a holding structure that can surely prevent the light receiving surface glass and the back surface glass from being bent due to vibration at the time.

  In order to solve the above problems, a holding structure of the present invention is a holding structure that holds a solar cell module in a horizontal state, and an edge holding body that holds a plurality of locations on the periphery of the solar cell module, respectively. And a center part holding body connected to the edge part holding body and holding the center part of the solar cell module.

  According to the present invention, the solar cell module is held at the peripheral portion at a plurality of locations and the central portion, so that the central portion of the solar cell module is bent up and down due to vibrations during transportation, in particular, the central portion is in the downward direction. Can be prevented from bending.

  In addition, the holding structure of the present invention includes a connecting body that connects the edge holding body and the center holding body. Thus, by setting it as the structure which connects an edge part holding body and a center part holding body with a connection body, only the center part part of a solar cell module can be reliably hold | maintained with a center holding body.

  Moreover, in the holding structure of the present invention, the edge holding body includes a base portion erected in the vertical direction and a support portion that protrudes in the horizontal direction from the base portion and supports the peripheral portion of the solar cell module. And a fitting portion that is fitted to another holding structure that is disposed adjacent to each other in the vertical direction is provided on the upper surface and the lower surface of the base portion. By providing the fitting portion in the base portion, the holding structure in a state where the solar cell module is held horizontally can be stacked in multiple stages in the vertical direction. In this case, since the holding structure holds the center part of the solar cell module with the center part holding body, the center part of the solar cell module can be prevented from curving downward due to vibration during transportation, etc. It is possible to prevent the solar cell module from being damaged due to contact with the surface of the solar cell module loaded on the lower side.

  In the holding structure of the present invention, the edge holding body holds each corner or each side edge of the solar cell module. According to such a structure, a solar cell module can be stably hold | maintained by hold | maintaining four places of the corner | angular part or side edge part of a solar cell module by an edge part support body.

  In the holding structure of the present invention, the central part holding body may have a structure that partially holds the central part of the solar cell module. Thus, by making the central holder a structure that partially holds the central portion of the solar cell module, the weight of the holding structure can be reduced while maintaining the holding strength.

  Moreover, in the holding structure of the present invention, the central portion holding body may have a bracing structure integrated with the connecting body. By making the central holding body and the connecting body a bracing structure that intersects at the central portion of the solar cell module, the central portion of the solar cell module can be reliably held with a small area.

  Moreover, in the holding structure of the present invention, the central holding body may have a lattice shape, a cross shape, a frame shape, or an annular structure. By adopting a grid-like, cross-shaped, frame-like, or annular structure for the central holding body, the weight of the protective structure and the material cost can be reduced while maintaining the holding strength of the central part of the solar cell module. Can be reduced.

  In the holding structure of the present invention, the solar cell module to be held is preferably a frameless structure solar cell module having no frame at the peripheral edge. Even if the solar cell module has a frameless structure without a frame at the peripheral edge, the solar battery modules can be stacked in multiple stages while being securely held without damaging the peripheral edge of the solar cell module.

  According to the present invention, the solar cell module is held at a plurality of locations and the central portion of the peripheral portion, so that the central portion of the solar cell module is bent up and down due to vibration, impact, etc. during transportation, particularly the central portion. Can be prevented from bending downward. As a result, when the holding structures in a state where the solar cell modules are held horizontally are stacked in multiple stages in the vertical direction, the solar cell modules adjacent to each other in the vertical direction come into contact with each other by bending displacement due to vibration or the like, and the solar cell modules are damaged. Can be prevented.
