Description

  The present invention relates to a photovoltaic power generation facility that also serves as a facility for cultivating short shoots of grapes.

Power generation using sunlight is one of the power generation methods that is currently attracting the most attention. As a matter of course, sunlight is necessary for the solar panels used to generate electricity to produce electricity.
On the other hand, sunshine is necessary for the cultivation of grapes. The vines grow by photosynthesis with the leaves of the grapes, but it is also necessary to shine the bunches of vines in order to color the grapes. However, rain and hail cause harm to the bunch of grapes. Recently, seedless grapes that can be eaten with the skin are popular. Rainfall wastes gibberellin processing to make seedless grapes. In addition, the leaching of the drug due to rain brings rust to the skin of the grapes, which makes it look bad.

  In order to prevent the damage in outdoor cultivation as described above, it has been proposed to provide a roof made of a transparent material such as vinyl in a tunnel shape on a grape shelf. For example, a main branch of each vine in a cultivation row planted at a predetermined interval is grown so as to extend in a direction parallel to the ground at a substantially constant height, and is generated from the main branch along its longitudinal direction. The length of each side branch is kept short by pruning each year so that the number of sprouts in the mother branch resulting in the side branch is two or one, and the new tree (resulting branch) resulting from the mother branch is directed downward A method for cultivating grapes in which the fruit grows in a state of being hung on the ground, wherein the top of the main branch extending parallel to the ground is covered with a transparent material roof in a tunnel shape, and the use of the method A suitable grape cultivation shelf (see Patent Document 1, page 1, abstract) has been proposed.

  In addition, in the case of outdoor cultivation, not only rain and drought but also excessive sunshine may cause harm to the cultivation of grapes. For example, excessively strong sunlight and high temperatures in summer can suppress the growth (photosynthesis) of grapes and cause sunburn and fruit shrinkage. Furthermore, in the fine weather after raining in the summer, grapes that have sufficiently absorbed moisture may expand and crack (crack) when heated suddenly by sunlight. To prevent such harm. A awning was needed in the bunch of grapes.

It is a perspective view which shows the example of a form of the solar power generation facility which serves also as the plant for short-tree cultivation of the grape which concerns on this invention. It is a side view which shows the other example of a solar power generation facility which also serves as the facility for cultivation of short shoots of grapes according to the present invention. It is a perspective view which shows the other example of the solar power generation facility which serves as the facility for short-tree cultivation of the grape which concerns on this invention.

Hereinafter, an example of a solar power generation facility that also serves as a facility for cultivating short shoots of grapes according to the present invention will be described in detail with reference to the accompanying drawings (FIGS. 1 to 4).
A photovoltaic power generation facility that also serves as a facility for cultivating short shoots of grapes is provided with a grape shelf 1 and a strip-shaped power generation panel array 20. In addition, FIG. 1 shows the example of only the grape shelf 1 in which short-tree cultivation is performed.

  The vine shelf 1 is a main branch 11 that is extended or branched from the main trunk 10 so that the main branch 11 is straight and extends parallel to the ground 50 at a certain height, and the main branches 11 are spaced apart in the longitudinal direction. The branch of the grape is fixed for use in the short-tree cultivation of the grape that is cultivated so that the bunch of grapes 13 will be settled on the new tree that has occurred on the side branch 12 by extending the side branch 12 from the plurality of parts to both sides. It is provided to support. The main branch 11 is extended and branched from the main trunk 10 so as to be grown in two rows from a single vine, and is extended and grown into a U-shaped or H-shaped tree shape. There are many cases. FIG. 1 is an example in which the main branch 11 is extended in an H-shape. There is also a method in which the main branch 11 is branched from the main trunk 10 in a T-shape and extended in one row.

  In the past, vines were often produced by shelf cultivation in which the main branch 11 was grown over the head. On the other hand, according to the short-tree cultivation according to the present invention, the main branch 11 of the vine is straightly extended, for example, from east to west and grown. This makes branching and pruning easy. Moreover, since one vine bunch 13 is fruited in each side branch 12, shoot management, fruit fruit adjustment, etc. are easy. The distance between the two grape bunches 13 located on both sides of the main branch 11 is kept at about 40 cm. By the way, although the direction which extends the main branch 11 is not specifically limited, the solar panel 21 can be arrange | positioned appropriately by extending east and west. However, it does not have to be strictly east and west, and may be arranged corresponding to the conditions of the installation location as appropriate.

  The grape shelf 1 holds a laterally long rod-like body 2 that holds and fixes the main branch 11 along the main branch 11 that extends from east to west, a support member 3 that is erected from the ground 50 that supports the rod-like body 2, and a side branch 12. The frame-shaped member 4 orthogonal to the rod-shaped body 2 to be fixed can be used. It does not specifically limit to the material which comprises this grape shelf 1. A wire, a metal pipe, or a rope can also be used. Further, the material may be wood, and a larch material having high durability may be used for the support member 3.

The strip-shaped power generation panel row 20 covers the bunch of grapes 13 from above so as to be able to prevent rain and awning, and in the longitudinal direction along the main branch 11 on the upper side of the main branch 11 so as to be able to generate power by sunlight. It consists of a plurality of solar panels 21 installed in a series of strips that extend.
As shown in FIG. 2, the solar panel 21 according to this embodiment has a rectangular shape, and is generally commercially available with a width of 80 to 90 cm and a length of about 160 to 180 cm. The width of the solar panel 21 having this general shape is sufficiently longer than the distance between the bunches 13 of grapes that are formed outside the main branch 11 in short-tree cultivation. Therefore, this solar panel 21 is suitable for rain protection and awning of grapes. And since the solar panel 21 can be arranged in a longitudinal direction along the main branch 11 of the grape extended in the east and west, it becomes the optimal for electric power generation. The size of the solar panel 21 is not particularly limited, but the cost can be reduced by using a solar panel 21 having a general size. The solar panel 21 may be one that uses, for example, a film-like solar cell that can transmit a certain amount of light in addition to completely blocking sunlight.

  As shown in FIG. 2, the solar panel 21 is supported by the support frame 5 and is held in a state of being inclined southward toward the sun trajectory. In this case, as shown in FIGS. 3 and 4, the grape shelf 1 can also be provided so as to serve also as a support frame for installing the solar panel 21. As a result, it is possible to save materials and space in the support frame body of the grape shelf 1 and the solar panel 21, and to firmly hold the solar panel 21.

The support frame 5 of the solar panel 21 or the grape shelf 1 that also serves as the support frame 5 can be provided with an angle adjustment mechanism 7 that can adjust the inclination angle of the solar panel 21.
According to this, in the case of rain or rainfall, the solar panel 21 can be kept horizontal so that the grape bunch 13 is not exposed to rain as much as possible. Further, in the summertime when the sunlight S is strong, the solar panel 21 can be inclined at an angle that most effectively blocks the sunlight S. On the other hand, in winter, the power generation effect can be increased by increasing the inclination angle of the solar panel 21 corresponding to the sun's trajectory so that the sunlight S hits the solar panel widely. As a result, solar power generation utilizing the breadth of the grape field is possible. In addition, by placing a reflection sheet on the ground 50, it is also possible to apply light to the bunch 13 of grapes while appropriately blocking sunlight.

The angle adjustment mechanism unit 7 can freely adjust the angle by incorporating a motor. Angle adjustment can be performed by remote control or automatically adjusted to an optimum angle by a computer. The solar panel 21 can be positioned about 50 cm above the position of the bunch 13 of grapes. For this reason, angle adjustment is not a difficult task even when manual adjustment is performed.
Furthermore, when the angle of the solar panel 21 is automatically adjusted by the angle adjustment mechanism 7, a sensor for detecting weather conditions such as a rain sensor, a temperature / humidity sensor, a sunshine sensor and an ultraviolet sensor is installed and detected by the sensor. The angle may be adjusted via a control device that outputs control information based on the information. This angle adjustment is controlled using computer software that has the function of predicting meteorological phenomena such as rainfall and temperature changes by inputting information from the above-mentioned sensors and weather information that can be acquired from the outside such as the Internet. The angle of the panel 21 may be adjusted.

  The angle adjusting mechanism unit 7 can also intermittently fix the solar panel 21 at every fixed angle. According to this, the solar panel 21 can be firmly fixed to withstand strong winds and snowfall. As an example of the intermittent fixing means, a connecting material may be connected to the solar panel 21 and fixed with a plurality of grooves or holes provided in the support frame 5 and bolts.

  A plurality of rows of main branches 11 are grown in parallel at a required interval, and the strip-shaped power generation panel rows 20 can be installed in a plurality of rows at a required interval corresponding to the plurality of rows of main branches 11. Thereby, similarly to the installation method of the normal solar panel 21, the solar panel 21 corresponding to the main branch 11 can be installed so as not to make a shadow on the solar panels 21 corresponding to the other main branches 11. For this reason, the power generation effect can be improved. The same applies to the case where the main branch 11 is extended in an H shape or a U shape. In addition, as a specific size, the space | interval of the main branch 11 grown in parallel can be 240 mm, and the width | variety of the support frame 5 can be 80-90 mm, for example. According to this, workability | operativity can be improved, such as driving | running | working the agricultural chemical spraying automobile.

  As described above, the present invention has been described in various ways with preferred embodiments. However, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. That is.
