  • the first chamber 8 and the second chamber 9 of the first embodiment are partitioned by the internal partition wall 7 as a fixed part, the left and right volumes do not change at all, but the first and second chambers 9 and 9 of the fifth embodiment are not changed.
  • the inner partition 7B is a flat rectangular synthetic resin container in the embodiment.
  • the inside of the internal partitioning body 7B is filled with a required amount of a material that can be a weight such as water or sand.
  • FIG. 20 is a schematic explanatory view in which the internal partition 7B has moved to one side
  • FIG. 21 is a schematic explanatory view in which the internal partition 7B has moved to the other.
  • FIG. 20 shows a state in which the right control valve 13 is “closed” and the left control valve 12 is “open”, and air A from the compressor 21 flows through the suction port 11b to the second partition 7B.
  • the flow into the second chamber 9 indicates that the internal partitioning body 7B, which is a weight, moves to the left side as indicated by an arrow due to air pressure, whereby the balance is lost and the hollow member 5B tilts to the left.
  • FIG. 21 shows an operation mode reverse to that of FIG.
  • a hollow member 5B whose center is pivotally supported at the upper end of the column 1 via the bearing member 3 having the horizontal shaft 3c, A solar panel (6) integrally provided on the upper surface, an air supply means (20) for supplying air to the hollow member, and a control means (30) for controlling the driving of the air supply means at a predetermined time; 5B, a first chamber 8 and a second chamber 9 whose volume is changed by the displacement of the slidable internal partitioning body 7B are provided independently of each other, and the first chamber and the second chamber are provided with air.
  • the outlets 10a, 10b and the inlets 11a, 11b through which the solar panel 6 enters and exits are provided, and the condition that the solar panel 6 changes from one inclined posture to the other inclined posture in a seesaw manner is connected via the connecting pipe 15.
  • Partner When air flows into one of the second chamber 9 and the first chamber 8 and the internal partition 7B slides due to air pressure, the gravitational balance between the first chamber 8 and the second chamber 9 is lost. Therefore, the hollow member 5B is automatically tilted to a predetermined angle by its own weight.
  • FIGS. 22 to 24 are schematic explanatory diagrams showing a sixth embodiment of the present invention.
  • This sixth embodiment is similar to the second embodiment in that a pump P is used as a drive source. However, the difference is that the hollow partition 5B is provided with an internal partition 7C that can slide inside. Another difference is that the discharge ports 10a and 10b and the control valves (sealing valves) 12 and 13 are not provided.
  • the sixth embodiment is the same as the fifth embodiment in that an internal partition is used.
  • the internal partition 7C of the fifth embodiment is a "heavy member”
  • the internal partition 7C of the sixth embodiment is a "light member”. Is a compressor 21, whereas the driving member of the sixth embodiment is a pump P.
  • the internal partition 7C of the sixth embodiment uses, for example, an empty substantially flat rectangular synthetic resin container.
  • the inner partition 7C may be a substantially flat rectangular plate made of a light material.
  • the inner partition 7C is made of a material that is easy to slide.
  • FIG. 23 is a schematic explanatory view in which the fluid W has moved to one side
  • FIG. 24 is a schematic explanatory view in which the fluid W has moved to the other side.
  • FIG. 23 shows that the water W existing in the second chamber 9 is put into the first chamber 8 via the pipes 18 and 19, and as the amount of water in the first chamber 8 increases, the empty internal partition 7C becomes empty. Has moved to the right side, whereby the balance has been lost and the hollow member 5C has tilted to the left.
  • FIG. 24 shows an operation mode reverse to that of FIG.
  • a hollow member 5C whose center is pivotally supported at the upper end of the column 1 via the bearing member 3 having the horizontal shaft 3c, A solar panel 6 integrally provided on the upper surface, a pump P for supplying a fluid W to the hollow member 5C, and control means 30 for controlling the driving of the pump P at a predetermined time, the solar panel 6 comprising: A first chamber 8 and a second chamber 9 whose volume is changed by the displacement of the slidable internal partition body 7C are provided independently of each other, and the solar panel 6 is moved from one inclined posture to the other inclined posture.
  • the present invention is installed on a flat surface on the ground, for example, and is used as a solar power generation device.

Abstract

La présente invention concerne un générateur d'énergie photovoltaïque qui comprend : un élément creux qui est supporté de manière pivotante à une extrémité supérieure d'un montant de support par l'intermédiaire d'un élément porteur qui a un axe horizontal au centre de celui-ci ; un panneau solaire qui est disposé d'un seul tenant sur une surface de dessus de l'élément creux ; un moyen d'alimentation en air pour fournir de l'air à l'élément creux ; et un moyen de commande qui est conçu pour commander l'entraînement du moyen d'alimentation en air à un moment prédéfini. L'élément creux comprend une première chambre et une seconde chambre qui sont prévues indépendamment l'une de l'autre. Les première et seconde chambres sont chacune pourvues d'un orifice d'échappement et d'un orifice d'admission à travers lesquels de l'air est introduit et évacué. L'état dans lequel le panneau solaire change d'attitudes d'inclinaison d'un type à l'autre type dans un mouvement de bascule est un déséquilibre gravitationnel entre la première chambre et la seconde chambre. Cette conception permet de maintenir des coûts d'installation, des coûts de maintenance et similaires à de faibles niveaux.
