Title:
UNDERWATER LINEAR POWER GENERATION DEVICE HAVING PARTITION CHAMBER
Document Type and Number:
WIPO Patent Application WO/2019/023834
Kind Code:
A1
Abstract:
An underwater linear power generation device having a partition chamber, comprising a main housing (1), a pull rod (2), a permanent magnet (4), a coil (3), a return spring (6) and a Y-shaped seal coil (5); the main housing comprises an outer housing, a sealed compartment (11), a partition chamber (12), a coil compartment (13) and a power storage compartment (14), the bottom of the main housing being fixed, the pull rod moving relative to the main housing when the pull rod is subjected to a pulling force; the pull rod comprises a pull ring (21), a movable rod (23) and a retaining ring (22); the movable rod is provided with a plurality of flat keys, the permanent magnet being mounted on the flat keys, the permanent magnet moving, when the pull rod moves, together with the pull rod and relative to the coil mounted in the coil compartment of the main housing, thereby generating a current; the pull rod is pulled back by means of the return spring, the retaining ring prevents the pull ring from moving away from the main housing, the water-tightness is guaranteed between the main housing and the pull rod by means of multiple layers of Y-shaped coils. A cluster formed by the device or by a plurality of such devices is used for a mooring system, or is connected to its own floating body to serve as a wave power generation system; the pull rod is driven by an external load to move relative to the main housing, and the device converts the mechanical energy into electric energy for storage or use.
