  • the present invention relates to a water utilization facility that uses a waterway that has a waterway force that is unlikely to overflow.
  • the top of the weir is designed to be high in order to improve water intake efficiency or power generation efficiency. For this reason, if a malfunction occurs in the water intake or generator, the amount of water that has been blocked increases and the water overflows the weir, making it easier for the water to overflow.
  • a discharge path 4 communicating with the generator 3 is provided near the bottom of the weir 1, and the generator 3 is operating normally. Occasionally, water flows out downstream of the weir 1 through the discharge channel 4. However, in the event of an emergency when the generator 3 is malfunctioning, water does not flow out of the discharge channel 4, and the water flow is blocked by the weir 1. Then, when the amount of water blocked increases, the water begins to overflow the weir 1. At this time, if the water depth h exceeding the weir 1 becomes high, water tends to overflow from the side wall 2 of the water channel 10.
  • the conventional water channel 10 is provided with the straight weir 1 and the overflow length of the weir 1 Because B is the shortest, the water depth h exceeding the weir 1 becomes high, and water easily overflows from the side wall 2 of the water channel 10! /.

  • the purpose is to provide water utilization facilities using waterways.

  • a hydroelectric power generation facility may be provided as the water utilization facility.
  • the overflow length of the weir becomes longer than in the case where a straight weir is provided in the water channel as in the prior art. Therefore, when the water depth over the weir becomes low, water overflows from the waterway. Therefore, it is possible to prevent water from overflowing from the waterway when water supply facilities are not in good condition.

It is a labyrinth type (see Fig. 1D). More specifically, in the case of the crank type shown in FIGS. 1A and 2, the weir 11 is bent in the water channel 10 twice. On the other hand, in the case of the concave type or convex type shown in FIGS. 1B and 1C, each is configured so as to be convex toward the downstream side or the upstream side of the water channel 10, both of which are located at the lowest in the water channel 10.

Abstract

L'invention concerne un système d'irrigation utilisant un canal d'eau. L'objectif de l'invention est d'empêcher que l'eau ne déborde du canal d'eau en cas de défaillance du système d'irrigation sans qu'il soit nécessaire d'installer un appareil spécial. À cet effet, dans les appareils de génération d'énergie hydraulique (100a à 100d) utilisant le canal d'eau (10), des déversoirs (11 à 14) sont disposés de façon à s'étendre transversalement en présentant des coudes dans le canal d'eau (10).
