Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydraulic power generation devices require shutting down operations for maintenance of water turbines or electric power generators, reducing efficiency and shortening device lifespan due to frequent start-stop cycles.
Innovation Solution
The device includes multiple water passage units with sealed inlets and outlets connected to containers beneath the turbines, allowing water to flow and drive remaining turbines during maintenance, keeping the system operational.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hydraulic power generation device is shut down for maintenance of water turbines or electric power generators, then the safety of maintenance personnel is ensured, but the operational efficiency is reduced and device lifespan is shortened
Solution Approach 1:
The hydraulic power generation device is divided into multiple independent water passage units, each with its own water turbine and electric power generator. This segmentation allows individual units to be maintained while other units continue to operate, resolving the contradiction between maintenance safety and operational efficiency by enabling parallel operation and maintenance of different segments.
Solution Approach 2:
The system maintains continuous power generation through multiple water passage units that can operate independently. When one unit undergoes maintenance, the others continue to generate electricity, ensuring the useful action of power generation continues without interruption, thus maintaining operational efficiency while ensuring maintenance safety.
2Ease of repair
If the hydraulic power generation device is frequently shut down and started for maintenance, then the maintenance needs are met, but the device lifespan is shortened
Solution Approach 1:
By dividing the system into multiple independent water passage units, the patent enables maintenance of individual units without shutting down the entire system. This reduces the frequency of overall system shutdowns, thereby extending device lifespan while maintaining ease of repair for individual components.
Solution Approach 2:
The system is designed with multiple redundant water passage units that can take over the load before maintenance is needed. This preliminary arrangement of redundant capacity allows maintenance to be performed on individual units without affecting overall system operation, reducing wear from frequent shutdowns while ensuring maintenance accessibility.

AI summary
A hydraulic power generation device includes a water passage unit (2) which has a high end and a low end, and multiple water turbines (3) are located above the water passage unit (2). Multiple containers (4) are located beneath the water passage unit (2) and located corresponding to the water turbines (3) respectively. The water passage unit (2) has an inlet (23) and an outlet (24) located corresponding to each of the containers (4). The inlet (23) and the outlet (24) communicate with the room (41) of the container (4) corresponding thereto. When one of the water turbines (3) or the electric power generator (5) needs to be maintained, the seal (25) of the inlet (23) is opened and the water flows to the water passage unit (2) via the outlet (24) to drive the water turbines (3) behind the damaged water turbine (3). The hydraulic power generation device is still under operation while one of the water turbines (3) is under maintenance.
