Improvement in power generation hydraulic circuit for hydroelectric plants

摘要

"HYDRAULIC POWER GENERATION IMPROVEMENT FOR HYDROELECTRIC POWER PLANTS". The present invention relates to the improvement developed in power generation hydraulic circuit for hydroelectric power plants, wherein the powerhouse structure (1) is connected to the water intake structure (2) through the arc-shaped cover. or vault (3) or portico (23), making the whole monolithic. An alternative construction of the improved generation hydraulic circuit has the water adduction located at the bottom of the water intake structure, near the rocky riverbed, which has a high mouth, directly feeding the turbines (5) turn the generators (6), without the need for forced conduits. Another alternative construction of the improved generation hydraulic circuit is the water adduction located at the top of the water intake structure, close to the water reservoir (17) of the dam reservoir. In this alternative there is a structured slab (18) extending the gangway (10) to support the crane (19) operating the cofferdam or emergency upstream gate (12). The water intake (4) has a lower mouth and its floodgates, having a large forced conduit (20) that feeds the turbines (5) that drive the generators (6). Yet another alternative construction of the improved hydraulic generation circuit for hydroelectric power plants, the water supply being located at both the top and bottom of the water intake structure, comprises a powerhouse (1) shaped cover. A very robust metal frame (23 39) gantry designed to compensate for weight relief when the thickness of the monolithic foundation slab is reduced.
