    • A control system for a ring gate (134) disposed in a hydraulic turbine installation in which water flows through a water passageway from an upstream reservoir past a turbine runner (126). The ring gate surrounds the runner and is mounted for longitudinal movement between an open position in which the water flow is unencumbered and a closed position in which the water flow is shut off. The control system includes a set of actuators (146), a set of operating rods, and an electrical control circuit. The actuators are installed above the ring gate and distributed around its circumference. Each operating rod is connected to the ring gate and an associated actuator. The electrical control circuit controls and synchronizes the actuators and thereby controls the movement of the ring gate. A turbine installation including the ring gate control system is provided along with a method for controlling the movement of the ring gate. A method of utilizing the actuators as a jacking system to lift the head cover and thereby ease maintenance is also disclosed.
    • 一种用于环形门(134)的控制系统,其设置在水力涡轮机设备中,水在其中流过来自上游储罐的水通道经过涡轮转轮(126)。 环形门围绕流道并且被安装用于纵向运动,其中水流不受阻碍的打开位置和关闭水流的关闭位置。 控制系统包括一组致动器(146),一组操作杆和电气控制电路。 执行器安装在环形闸门上方并围绕其圆周分布。 每个操作杆连接到环形闸门和相关联的致动器。 电气控制电路控制和同步致动器,从而控制环形门的移动。 提供包括环形闸门控制系统的涡轮机装置以及用于控制环形闸门运动的方法。 还公开了一种利用致动器作为顶起系统来提升头盖并由此简化维护的方法。

    • This invention relates to a submersible hydroelectric generator apparatus (1) and a method of evacuating water from such an apparatus. The method of evacuating water from a submersible hydroelectric generator apparatus (1) comprising the steps of pressurizing a fluid supply in the submersible hydroelectric generator apparatus using the water flowing into the apparatus and thereafter using the thus-pressurized fluid supply to evacuate the water from the apparatus. Additional pressurized fluid can be supplied to provide a pressurized fluid supply with sufficient pressure to expel the water from the apparatus. The apparatus (1) can be used in a grid connected electricity generating system or indeed in a smaller scale implementation such as in a single building or group of buildings to provide electricity to those buildings. The invention overcomes problems with prior art devices by evacuating water from the apparatus in an efficient manner.
    • 本发明涉及一种潜水式水电发电机装置(1)和从这种装置中排出水的方法。 从潜水式水电发电机装置(1)排出水的方法包括以下步骤:使用流入设备中的水对浸入式水力发电装置中的流体供应进行加压,然后使用这样加压的流体供应源将水从 仪器。 可以供应额外的加压流体以提供足够的压力以从设备排出水的加压流体供应。 设备(1)可以用于并网发电系统中,或者实际上用于较小规模的实施中,例如在单个建筑物或一组建筑物中,以向这些建筑物提供电力。 本发明通过以有效的方式从装置中排出水来克服现有技术装置的问题。
