The invention discloses an autonomous hydraulic controller of a wave energy conversion device. The autonomous hydraulic controller comprises a main oil path of a hydraulic system in the wave energy conversion device, an oil tank, a hydraulic valve, a hydraulic cylinder, a measuring energy storage device, a slide block, a sliding chute, a first ball valve and a second ball valve, wherein the hydraulic valve is used for controlling opening and closing of the main oil path; the hydraulic cylinder is used for hydraulic transmission; the measuring energy storage device is used for pre-charging gas; the first ball valve and the second ball valve are provided with a first forked handle and a second forked handle respectively; the two ends of the slide block are crosswise provided with a first poke rod and a second poke rod respectively; and the hydraulic valve is provided with a pilot block for controlling opening and closing of the hydraulic valve. By using the autonomous hydraulic controller, autonomous work of the wave energy hydraulic conversion system can be realized, i.e., the hydraulic system realizes system pressure self-control by means of combination of pipelines and elements of the system, so that a non-hydraulic control mechanism which simultaneously occurs in the system is avoided; and thus, on one hand, the failure rate of the control system is greatly reduced, and on the other hand, the power for executing control action by a hydraulic autonomous control system is provided by the hydraulic autonomous control system itself.
Description
technical field [0001] The invention relates to a hydraulic control technology of a wave energy conversion device, in particular to an autonomous hydraulic controller of a wave energy conversion device. Background technique [0002] Wave energy conversion devices are usually used in the field of ocean wave power generation. They need to face ever-changing ocean dynamic conditions under unmanned conditions, and their working conditions are characterized by independent operation and seawater environment. In view of the working condition characteristics of the wave energy conversion device, its design must maximize the realization of autonomous control and reduce the complexity of external control facilities to reduce its failure rate. At present, the conversion mode of the wave energy conversion device is mainly hydraulic conversion, and the hydraulic system is mostly controlled by a solenoid valve control device. However, the solenoid valve control device often has the follo...
