Mixed wave force power-generating device

Abstract

The invention discloses a mixed wave force power-generating device. The device is characterized by containing two parts, namely an upper floating body and a lower floating body, wherein the upper floating body is hollow, one side of the upper floating body is provided with an opening, the hollow part of the upper floating body is provided with a float which is used to heave with waves; the inside of the lower floating body is provided with a conductive coil, a hydraulic cylinder, a hydraulic motor, a generator and a storage battery; the hydraulic cylinder is connected with the hydraulic motor through a hydraulic pipeline, the output shaft of the hydraulic motor is connected with the input shaft of the generator through a coupling; the float in the upper floating body is connected with the piston of the hydraulic cylinder through a connecting rod; the conductive coil which encircles the connecting rod and has multiple turns is arranged on the upper part of the hydraulic cylinder and is fixed relatively to the hydraulic cylinder; a magnet is fixed on the connecting rod and corresponds to the conductive coil; the output end of the conductive coil and the current output electrode of the generator pass through a rectifying unit to be connected with the storage battery. By adopting the device, the wave energy conversion efficiency of the system can be increased and power can be generated more stably; and the influence of marine organism on the device is small and the device has low cost and is suitable to be widely popularized.

Description

technical field [0001] The invention relates to a device for providing energy for a navigation mark, in particular to a hybrid wave power generation device which converts wave energy into electric energy based on electromagnetic principles, hydraulic drive principles and wave theory. Background technique [0002] As a kind of green natural energy, the total amount of wave energy is huge. Due to the special use occasions of navigation marks, wave power generation has become one of the most promising navigation mark energy sources. [0003] At present, the wave power generation devices used in navigation marks are mainly pneumatic devices, which are divided into two categories: one is the impact type air turbine wave power generation device with rectification valve; the other is the new symmetrical wing air turbine wave power generation device. power generation device. Its common working principle is that there is a centrally connected pipeline in the center of the buoy of t...
