Description

  The present invention relates to a solar power generation device.

  At present, solar power generation devices are widely used in ordinary households and businesses. The solar power generation device has a solar power generation panel (hereinafter referred to as a solar panel). The solar panel is installed on a roof of a residential house or a commercial facility, and the sunlight hits the solar panel. Power generation is performed.

  By the way, since solar power generation is a power generation mode with very little burden on the environment, there is a high need for use in various places and scenes. However, solar panels are usually firmly fixed to the roofs and walls of structures so that they do not fall, making it almost impossible to use them outside of their planned installation locations and usage scenes. In addition, by reducing the size of solar power generation devices, especially solar panels, it may be possible to expand the usage scenes and places of use, but in this case, another problem arises that the required amount of power generation cannot be obtained. sell.

  In relation to the above, there is one disclosed in Patent Document 1 as a configuration in which the photovoltaic power generation device is configured to be movable. This mobile solar system consists of a mobile vehicle with wheels, a box that is mounted on it and that includes charging and control functions, and a solar panel that is placed on the box so that its posture can be changed. I have.

  However, such a system has a configuration that is very heavy, and eventually there is a problem that places and scenes that can be used for power generation are limited. In addition, if the size of the solar panel is increased to obtain the required amount of power generation, there is a high possibility that the size of the mobile vehicle will increase, and the final size and weight increase of the entire photovoltaic power generation device cannot be avoided. The problem arises.

  Patent Document 2 discloses a solar cell module that can be further reduced in weight as compared to the mobile solar system. In this solar cell module, a plurality of panels are configured to be folded by a hinge composed of a hinge knuckle and a pintle. Further, the folded and overlapped module panels are rolled up in a roll and moved together. Was intended to be.

  However, the solar cell module is based on the premise that it is wound up in a roll shape, and maintenance of flexibility is essential. Therefore, there is a problem that the module and the hinge are damaged during repeated use. In addition, since it is a configuration in which flexibility is emphasized, a bar-like support member such as a tent frame is separately required when setting it toward sunlight during use. However, it is difficult to use in a windy place, and in practice, the installation location and usage scene are often limited.

  Further, as shown in the reference portion III of FIG. 3, the fastening portion 21 faces the other fastening portion 21 that overlaps in the folded state (contacts in the present embodiment) and is adjacent in the deployed state. It has the role which separates both so that the photovoltaic power generation films 5 in each other may not rub against each other in the folded state.

  As shown in FIG. 7A, each unit panel portion 9 is sandwiched between the first plate portion 51 and the second plate portion 52 forming the front and back surfaces of the panel and the plate portions. And a concave-convex reinforcing wall portion 53 that is positioned at a distance. The uneven reinforcing wall portion 53 extends corresponding to the direction in which the surfaces of the first plate portion 51 and the second plate portion 52 extend, and unevenness is formed. The unevenness is formed so as to produce a thickness of the unit panel portion 9. Furthermore, in this embodiment, as an example, the uneven reinforcing wall portion 53 has a truss-like structure, and specifically, the unevenness is a triangular pyramid as well shown in FIG. It has the form which includes the wall surface which comprises. Thereby, each unit panel part 9 has the characteristics of being highly rigid and ultralight.

  According to the photovoltaic power generation apparatus according to the present embodiment configured as described above, a sufficient number of photovoltaic power generation films can be mounted in the entire photovoltaic power generation apparatus, so that a sufficient amount of power generation can be easily obtained. And, since a sufficient number of photovoltaic power generation films can be deformed and supported by a rigid panel with an uneven reinforced wall inside, it can be moved and set in a place that does not involve a sturdy base It is easy to use in various places and scenes and has excellent durability. Therefore, the solar power generation device of the present embodiment can be easily used in, for example, a temporary facility, a temporary enclosure at a construction site, an evacuation site at the time of a disaster, and the like. Moreover, it can also be used by making it stand like a folding screen in the semi-deployed state illustrated in FIG. Furthermore, extremely high rigidity is acquired by providing the rigid panel which has an uneven | corrugated reinforcement wall part inside. Therefore, it can sufficiently withstand transportation in a mode that requires structural strength and solar power film protection, such as mounting on a vehicle carrier. Furthermore, it is possible to provide transportation support means such as embedded or detachable casters at appropriate locations such as in the vicinity of the peripheral edge of the rigid panel, thereby promoting the use in various places and scenes. it can.

  In addition, since the holding portion can apply a pressing force from the front surface side of the photovoltaic film, reliable support is easily maintained compared to the case where the back surface side of the photovoltaic film is simply adhered to the support surface. ing.

  In addition, the fact that the rigid panel can be folded contributes to facilitating the movement of the photovoltaic power generation device. In this case, the rigid panel takes the folded state, so that the photovoltaic power generation film May be damaged by mutual contact. However, according to the present invention having the fastening portion as described above, it is possible to prevent the photovoltaic films from rubbing with each other, and it is possible to facilitate the movement by taking the folded state. Damage can also be prevented. In addition, such damage prevention is not an addition of a dedicated member, but is an effect obtained by the fastening part for improving the holding property of the photovoltaic film in the deployed state, and the retaining part has a function of improving the retaining property in the deployed state. It can be used in two functions: a damage prevention function in the folded state. This also leads to a reduction in the number of parts, which in turn contributes to the suppression of the increase in the weight of the apparatus, thereby facilitating movement.

  Also, each terminal box is embedded in the corresponding unit panel part so that it is within the thickness of the unit panel part, so that the terminal box increases the thickness of the photovoltaic power generation device or contacts the photovoltaic power generation film It is possible to prevent the terminal box from being bulky and causing film damage.

  Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention. It is self-explanatory.
