Description

  The present invention relates to a portable solar power generation device, and more particularly to a portable solar power generation device that can be easily installed on site such as a disaster-stricken area.

  A solar power generation apparatus is generally installed on a roof of a building as a solar panel. However, if the solar power generation device itself can be moved to a portable type, for example, if a solar power generation device can be brought to the site in a simple manner and installed easily in the event of a disaster such as an earthquake, typhoon, or tsunami, a large amount of Can be deployed. Further, if the photovoltaic power generation apparatus can be easily moved even in the same area, more efficient energy supply can be achieved.

  In rural villages, mountainous areas, remote islands, etc., where depopulation and aging are progressing, it is difficult to maintain a permanent power supply facility in an emergency. Therefore, for example, if a portable solar power generation device is prepared in a public facility such as a government office, a city hall, or a public hall, it can be brought in anytime and anywhere to supply power temporarily. Furthermore, after use, it can be returned to its original location for permanent installation and re-activated in the next emergency. Note that this solar power generation device can be used at all times, not only in the event of a disaster such as an earthquake, typhoon, or tsunami, and in any region, not limited to rural villages, mountainous areas, remote islands, etc. It goes without saying that can also be used.

  Patent Document 1 discloses a portable solar power generation apparatus that can generate a stable and efficient power generation state with good workability, is excellent in use, and has practicality. Here, as a photovoltaic power generation unit, a photovoltaic power generation sheet and a roller that winds up the photovoltaic power generation sheet are built in, and the photovoltaic power generation sheet is wound around the roller and retractably stored and pulled out from the storage case. It describes that a sheet supporting means for supporting a photovoltaic power generation sheet and holding it in a posture extending obliquely upward is provided.

  Patent Document 2 discloses a portable solar power generation device that can be easily housed and deployed with a simple structure in which a winding roller is omitted. Here, a flexible photovoltaic power generation sheet that can be wound in a cylindrical shape along the longitudinal direction, and connected to one end side in the longitudinal direction of the photovoltaic power generation sheet, and wound in a tubular shape from the other end side. It is described that it is composed of a cover sheet having the same flexibility that is wound around the outer peripheral surface of the solar power generation sheet and accommodates the solar power generation sheet in a cylindrical state.

  Patent Document 3 discloses a solar power generation apparatus that can efficiently ensure a certain amount of power generated by sunlight even in a time zone where the energy of sunlight is low. Here, the solar power generation device is provided inside the solar photovoltaic power generation unit in which a plurality of film type solar cell panels wound in a cylindrical shape are stacked, and the cylindrical solar power generation unit, and holds the solar cell panel A panel holding unit, a solar power generation unit that is installed so as to surround the solar power generation unit in the circumferential direction, a solar reflection unit that reflects sunlight by a concave curved surface and projects the solar cell panel, and a curved surface shape of the solar reflection unit It is described that a curved surface driving unit to be changed and a curved surface control unit for controlling the operation of the curved surface driving unit are provided.

  In Patent Documents 1 to 3 described above, portable solar cell power generation sheets are employed. Silicon is used as a material for the solar cell power generation sheet. This silicon is roughly classified into crystalline silicon and amorphous silicon. Among these, the solar cell using amorphous silicon is classified into a thin film silicon type having a thickness of 10 μm or less. This is because the light absorption coefficient is high, so that practical use is possible even if the thickness is small. And it has the characteristic that an output does not fall easily at high temperature compared with the solar cell using crystalline silicon. Furthermore, it has a characteristic of high efficiency under extremely low illuminance. On the other hand, solar cells using crystalline silicon have hitherto been required to have a silicon layer of at least about 200 μm in order to obtain a practical amount of absorption due to a low light absorption coefficient. Solar cells that can be classified into thin film silicon types such as μm to 50 μm have been developed.

  A film type solar cell panel in which the thickness of the crystalline silicon or amorphous silicon silicon layer is reduced has been put into practical use. Since it is made into a thin film, flexibility like a film is obtained and the weight is light and flexible. Therefore, it is adopted in a place where it is difficult to apply to a flat solar cell panel using a conventional crystalline silicon such as a curved roof. A film-type solar cell panel in which the thickness of this silicon layer is reduced has a characteristic that it can be freely adapted to the situation.

  In solar power generation, in order to obtain a larger amount of power generation, the azimuth and inclination angle for installing the solar power generation panel are important. The south is optimal for the direction, but the inclination angle must be set according to the solar altitude because the altitude of the sun changes with the seasons. That is, it is most efficient to install so that sunlight hits the surface of the solar panel at a right angle. However, it is not realistic to automatically change the inclination angle of the photovoltaic power generation panel according to the solar altitude. Therefore, in the portable solar power generation device of the present invention, since it is brought into the disaster area and installed, the direction can be set to the south, and the inclination angle is set in consideration of the annual optimum inclination angle. . For example, in Tokyo, the annual optimum inclination angle is about 30 degrees. Alternatively, the annual optimum inclination angle may be calculated by attempting simulation of the amount of power generation in a rural area, a mountainous area, a remote island where the aging is declining, or a disaster area where a disaster has occurred.

  In regions where depopulation and aging are progressing in rural villages, mountainous areas, remote islands, etc., there is a case where normal power supply is insufficient and there is a problem that costs increase because new power is supplied. Also, when disasters such as typhoons, earthquakes, and tsunamis occur, the normal power supply is often interrupted, and portable solar power generation equipment must be brought into the disaster area and other areas to secure the necessary power. Is required. However, in order to make the solar power generation device portable, the solar power generation device itself must be downsized. As a result, the amount of power generation is reduced and the power generation efficiency of the device is lowered. That is, there is a problem that the power generation cost per unit power is higher than that of normal power.

  Moreover, a solar power generation apparatus may employ | adopt a solar cell panel with a larger light-receiving area in order to solve the problem mentioned above. However, when the light receiving area of the solar cell panel is increased, there is a problem that it is not easy to carry and takes a place during installation.

  In addition, power generation using a solar power generation apparatus has a problem that it is difficult to ensure the amount of power generation during rainy or cloudy weather when the energy of sunlight is reduced, or at sunset or at night. Therefore, how to efficiently secure the amount of power in these situations becomes a problem.

  The purpose of this application is a portable solar that can solve such problems, is easy to carry to the field, can be installed anywhere on the site, and efficiently collects sunlight to increase power generation efficiency. It is to provide a photovoltaic device.

  In order to achieve the above object, a portable photovoltaic power generator according to the present invention divides a rectangular parallelepiped power generator main body into a stationary power generator main body and a rotary power generator main body, and has a mirror surface on the surface of each opposing power generator main body. The curved power generation surface is formed by rotating the rotation-side power generation device body with a connector provided on the side surface of the rectangular parallelepiped, and the curved power generation surface to which the power generation layer of the semi-cylindrical solar power generation panel is attached is used as the curved reflection surface. The solar cell is arranged so that solar power is generated by adjusting the height position of the half-cylinder solar power generation panel with an elastic body.

  With the above configuration, the portable solar power generation device is divided into a fixed-side power generation device main body and a rotary-side power generation device main body in advance at a site where disasters such as typhoons, earthquakes, and tsunamis occur (hereinafter simply referred to as “local”). The rectangular parallelepiped power generator main body is brought into the closed state, and the rotating side power generator main body is rotated with respect to the stationary power generator main body toward the sunlight by a connector provided on the side of the rectangular parallelepiped. Can be made. As a result, it is easy to carry and can be carried in and installed on-site without taking up space.

  In addition, the curved power generation surface of the semi-cylindrical solar power generation panel can be arranged toward the curved reflection surface including a mirror surface provided on the surface of each power generation device main body. And by adjusting the height position of a semi-cylinder solar power generation panel with an elastic body, sunlight can be reflected intensively on the curved power generation surface to generate solar power. In addition, solar power can be generated by directly projecting sunlight onto the top of the semi-cylindrical solar power generation panel, and the power generation efficiency can be increased by efficiently collecting sunlight.

  As described above, in the portable solar power generation device, a portion that reflects sunlight is a curved reflection surface that is curved, and a portion that receives reflected sunlight is similarly a curved power generation surface that is curved. Thus, sunlight can be efficiently collected to increase power generation efficiency, and the system itself can be made compact.

  In addition, the portable solar power generation device includes a horizontal rotation type solar power generation device that rotates about the longitudinal direction of the rotation-side power generation device body as a rotation axis, and a vertical rotation that rotates about the short direction of the rotation-side power generation device body as a rotation axis. The vertical rotation type solar power generation device includes an angle adjustment mechanism provided in the stationary side power generation device main body, the angle at which sunlight is received is adjusted, and the horizontal rotation type solar power generation device is It is preferable that the angle at which sunlight is received is adjusted by an inclination angle adjustment mechanism provided in the stationary power generation device main body and the rotation side power generation device main body. In other words, when the power generator main body is closed and brought into the field, the fixed-side power generation is performed by contracting the elastic body connected to the half-cylinder solar power generation panel for the stationary power generator main body and the rotation-side power generator main body. It can be accommodated in the gaps between the curved reflecting surfaces of the apparatus main body and the rotation-side power generation apparatus main body. This makes it possible to incorporate the semi-cylindrical solar power generation panel compactly inside the portable solar power generation device when bringing it into the site, and the portable solar power generation device is easy to bring into the local area. It can be installed locally without taking up space.

  In addition, the portable solar power generation device includes a semi-cylinder solar power generation panel connected to the fixed-side power generation device main body by an elastic body, and the elastic body is contracted to each of the fixed-side power generation device main body and the rotation-side power generation device main body. It is preferable to be housed and confined in the gap between the curved reflecting surfaces and transported to the site. Thereby, the elastic body is contracted in advance to be compact, and can be accommodated in the gaps of the curved reflecting surfaces of the stationary power generation device main body and the rotation side power generation device main body. And it can confine and convey in a rotation side power generation device main body and a stationary side power generation device main body, respectively.

  Further, in the portable solar power generation device, when the rotation-side power generation device main body is separated from the stationary power generation device main body, the elastic body extends to a preset height position, and the sunlight reflected by the curved reflection surface is bent. It is preferable to project on the power generation surface. Thereby, when bringing in a field, a photovoltaic power generation panel can be made into the preset height position by separating a rotation side power generation device main body from a fixed side power generation device main body. And an elastic body can be extended to the preset height position in any of the rotation side power generation device main body and the stationary side power generation device main body.

  In addition, the portable solar power generator has a semi-cylinder solar power generation panel having a pin hole for position fixing on the side surface, and the extended elastic body is provided on the side surface of the main body of the fixed power generation device facing the position fixing pin. It is preferable that the height position be fixed to a position fixing opening provided at a desired height position. Thereby, a photovoltaic power generation panel can be easily fixed to a desired height position.

  In order to achieve the above object, a portable photovoltaic power generator according to the present invention divides the longitudinal direction of a rectangular parallelepiped power generator main body into a fixed power generator main body and a rotary power generator main body diagonally, and faces each surface side Of the semi-cylindrical photovoltaic power generation panel having a curved power generation surface and a flat plate power generation surface by forming a mirror-like curved reflection surface on the surface and rotating the rotation-side power generation device main body by a connector provided on a lateral surface of the rectangular parallelepiped. A curved power generation surface is arranged facing the curved reflection surface, and solar power is generated by adjusting the height position of the half-cylinder solar power generation panel with a height adjustment mechanism.

  With the above configuration, the portable photovoltaic power generator cuts the longitudinal direction of the rectangular parallelepiped power generator main body diagonally when dividing the rectangular parallelepiped power generator main body into the stationary power generator main body and the rotary power generator main body. When the rotation-side power generation device main body is rotated by this operation, the photovoltaic power generation panel can receive sunlight with an angle with respect to sunlight, and the above-described tilt angle adjustment mechanism is not necessary.

  The portable solar power generator is adjusted to a predetermined angle with respect to sunlight when the semi-cylinder solar power generation panel divides a rectangular power generator main body into a stationary power generator main body and a rotary power generator main body. Is preferably opened. Thereby, adjusting the height position of a half cylinder type photovoltaic power generation panel can be set when dividing | segmenting a rectangular parallelepiped power generation device main body into a stationary power generation device main body and a rotation side power generation device main body.

And it is preferable to connect a rotation side power generation device main body. Thus, by setting the height position of the semi-cylindrical photovoltaic power generation panel, the fixed-side power generation device main body and the rotation-side power generation device main body can be arranged in a straight line to facilitate wiring and the like.

It opens and adjusts the height position of the hemispherical solar power generation panel to receive sunlight reflected by the solar light reflection panel to generate power. Moreover, the top part of the hemispherical photovoltaic power generation panel can directly receive sunlight and generate power efficiently. In the present embodiment, the number of sunlight reflecting panels is four, but is not limited to this number, and may be an arbitrary number such as six or eight.

  In addition, the portable solar power generator is configured such that the solar reflective panels are connected in a cross shape to each side of the quadrangle, and the solar reflective panels are opened and closed with a wire extending in a cross shape. Is preferred. Thereby, a sunlight reflective panel can be freely opened and closed with the wire which connects the sunlight reflective panels which oppose. That is, when the solar reflective panel is transported, the solar reflective panel is closed by lifting the wire connecting the solar reflective panel in a cross shape upward. Then, the sunlight reflecting panel opens by lowering the wire lifted upward, and the sunlight is reflected on the hemispherical photovoltaic power generation panel to generate power.

It opens and adjusts the height position of the inverted cone solar power generation panel to receive the sunlight reflected by the solar light reflection panel and generate power. Thus, in order to reflect sunlight and project on a photovoltaic power generation panel by the sunlight reflecting panel having a curved surface, the photovoltaic power generation panel needs to have an inverted conical shape. In addition, the top of the inverted conical solar power generation panel can directly receive sunlight and generate power efficiently.

In the present invention, this height adjusting mechanism is, for example, the spring 8a, but other members may be used as long as they are elastic. The spring 8a expands upward when the rotation-side power generation device main body 2b is rotated and opened with respect to the fixed-side power generation device main body 2a at the site, and as shown in FIG. The power generation panel 3a is pushed up.

As shown in FIG. 3C, the photovoltaic power generation panel (fixed side) and the photovoltaic power generation panel (rotation side) each have a photovoltaic power generation surface that receives sunlight 10 and generates power. This solar power generation surface is composed of a curved power generation surface 4a and a flat plate power generation surface 4b. The curved power generation surface 4a is a part that is provided below the half-cylinder solar power generation panel 3a and receives sunlight 10 reflected by the curved reflection panel 5a. The flat power generation surface 4b is a flat end provided on the upper part of the half-cylinder solar power generation panel 3a, and is a part that directly receives the sunlight 10 to generate power. The curved power generation surface 4a and the flat power generation surface 4b have a solar power generation layer 4e that receives the sunlight 10 and generates power on the surface.

(Sunlight reflection part)

Have The sunlight reflecting panels 5 provided on the fixed side and the rotating side each have a sunlight reflecting portion 6 that is mirror-finished to reflect the sunlight 10 on the curved surface and project it onto the curved power generation surface 4a. Accordingly, among the sunlight 10 falling on the stationary power generation device main body 2a and the rotation-side power generation device main body 2b, the sunlight 10 poured on the peripheral portion is projected on the curved power generation surface 4a in a concentrated manner to generate solar power. The solar light 10 that has been poured into the center portion performs solar power generation on the flat power generation surface 4b. 3 (b) shows the spring 8a in a compressed state, and FIG. 3 (c) shows the projection of sunlight 10 on the spring 8a after being opened and extended upward. .

(Height adjustment mechanism)
FIG. 4 shows, from the side, how the photovoltaic power generation panel rises by the spring 8a for the stationary power generation device main body 2a and the rotation power generation device main body 2b. FIG. 4A shows the rise of the photovoltaic power generation panel viewed from the short side direction 11b, and FIG. 4B shows the rise of the photovoltaic power generation panel viewed from the long side direction 11a. In the solar power generation panel, the sunlight 10 reflected by the curved reflection panel 5a must be projected intensively on the curved power generation surface 4a. Therefore, the spring 8a which is an elastic body which raises the height position of a photovoltaic power generation panel is provided. In this application, the case where the spring 8a which is an elastic body is used is shown as an embodiment of the height adjusting mechanism. The spring 8a is compressed and stored in the gap between the curved reflection panels 5a of the fixed-side power generation device main body 2a and the rotation-side power generation device main body 2b.

  The height adjusting function for raising the photovoltaic power generation panel is not limited to the spring 8a that is an elastic body, and other methods may be used. For example, you may use the height adjustment function which raises a photovoltaic power generation panel to predetermined height by a folding type like the rhombus pantograph which is a current collector used for a railway vehicle. Alternatively, it may be a height adjustment function that lifts the photovoltaic panel to a predetermined height by applying a portal lifter, and the photovoltaic panel is predetermined by changing the angle of the parallelogram frame with the contact pin-joined. The height adjustment function that lifts to the height of the
