  • the rotation is not transmitted to the other rotational coupling bodies 16 b to 16 e. Therefore, the rotation of the rotational coupling body 16a does not affect the other rotational coupling bodies 16b-16e.
  • power generation is performed in accordance with the descent of the heavy object 15 in the series of the rotating joints 16 a, that is, the release of potential energy due to the descent of the heavy object 15.
  • the first 15 Actuate electromagnet 2 7 to engage ratchet 1 3 of that series with ratchet pawl 2 6 and actuate solenoid 2 5 of the same series to activate arm 2
  • the collar 1 8 a can be moved forward in the direction close to the ratchet 1 3 of the rotary coupling 1 6 a by 4, and the projection 2 1 of the collar 1 8 a can be engaged with the small shaft 2 3 of the ratchet 1 3 State.
  • the first series of heavy objects 15 is stopped from descending, and thereafter, the heavy objects 15 can be rolled up as the floating structure 1 ascends.
  • the second series of electromagnets 16 b Remove the ratchet pawls 2 6 of that line from the ratchet 1 3.
  • the rotational coupling body 16 b including the second reel 1 1 b can be freely rotated, and in the same manner as described above, the rotational coupling body 16 6 b has a long length from the reel 1 1 b.
  • the second series of heavy objects 1 5 suspended by the scale 1 4 starts to descend, and the second series of rotary couplings 16 b including the reel 1 1 b rotate, Further, the rotation is transmitted from the shaft 5 to the rotating shaft 33 of the generator 32, and power is generated.
  • the amount of sea level rise by one wave is the same as the amount of heavy object 15 raised (the amount of rise). If the mean significant wave height at 2m is 2m and the significant wave period is 8 seconds, the heavy object 15 will rise 2m by one wave, and it will rise 2m again by the next wave coming after 8 seconds. On average, it will rise by 0.25 m per second.
  • the average subsidence rate (lmZ sec) is 1Z4 average ascending rate, so if you prepare 4 heavy objects and shift their ascending / descending timing by 1/4 each, By looking at the balance between the settlement speed and the ascending speed, complete continuous power generation becomes possible. However, in actuality, it is desirable to look at a slight margin, so in the example, five series of heavy objects are provided. By sequentially raising and lowering them, 24-hour continuous power generation becomes possible.
  • the chains 8 A and 8 B are used as the long strips, and the chain wheels 7 A and 7 B are used as the hanging rotary bodies for hanging them.
  • a combination of sprockets, a timing pulley and belt, a flanged pulley and a rope may be used.
  • the wave energy storage device and the power generation device of the present invention are installed on the ocean, they are useful as a device for storing and a device for generating power using the wave energy.

Abstract

L'invention concerne un dispositif de stockage de l'énergie des vagues et un générateur d'énergie l'utilisant. Lorsque l'énergie des vagues est utilisée pour la génération d'énergie électrique ou similaire, elle est stockée de manière efficace à moindre coût par un dispositif simple, et peut être utilisée pour la génération d'énergie électrique à tout moment. Le dispositif de stockage d'énergie des vagues comprend une structure flottante flottant sur la surface de la mer, un corps long souple pendant dans la mer à partir de la structure flottante avec un poids fixé à l'extrémité inférieure, et des moyens pour hisser le corps long jusqu'au côté de la structure flottante par l'un des mouvements vers le haut et vers le bas de la structure flottante liés à l'élévation ou à la baisse de la surface de la mer en raison de la vague pour élever la position du poids et maintenir la position hissée vers le haut, stockant ainsi l'énergie des vagues en tant qu'énergie potentielle du poids. De plus, un mouvement descendant produit lorsque le hissage/maintien du corps long est relâché et le poids est abaissé est transmis comme mouvement de rotation à un générateur, générant ainsi une énergie électrique.
