Embodiment Construction
[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0038] From Figure 1 to Figure 13 It can be seen that the present invention provides three embodiments of a catamaran wave energy generating device. The commonality of the three embodiments is that the catamaran wave power generating device includes a support frame 10, a first float 21, a second float 22, and a generator 30. and a positioning member 40; the stator of the generator 30 is arranged on one end of the lengthwise direction of the support frame 10, and the rotor of the generator 30 is connected to the first float 21 so that relative rotation can be carried out between the first float 21 and the support frame 10; The second float 22 is mounted on the support frame 10 in a movably manner, and the moving track of the second float 22 is consistent with the length direct...

The invention discloses a pitch adjustable double-body wave power generation device based on a rotation motor. The pitch adjustable double-body wave power generation device comprises a supporting frame, a first floater, a second floater, a power generator and locating elements. A stator of the power generator is arranged at one end of the supporting frame in the length direction. A rotor of the power generator is connected with the first floater so that the first floater can rotate relative to the supporting frame. The second floater is movably mounted on the supporting frame. The moving trackof the second floater is consistent with the length direction of the supporting frame. The locating elements are detachably connected with the second floater and the supporting frame. The locating elements are used for fixing the installation position of the second floater. Pitch adjustment of the power generation device can be realized by moving the second floater. Accordingly, the problem thatpitch adjustment of an existing power generator is hard to realize is solved.
Description
technical field [0001] The invention relates to the technical field of wave energy, in particular to a two-body wave energy generating device with adjustable pitch based on a rotating electrical machine. Background technique [0002] The world's energy crisis is intensifying, and people are turning their attention to the ocean. The ocean contains huge energy, among which wave energy is one of the main forms of ocean energy. It has the advantages of huge reserves, cleanness, and regeneration, and is considered to be a new direction to solve energy problems. my country's wave energy resources are considerable, and the energy flow density in the offshore sea area is high, which has very broad development prospects and is of great significance to the transformation of the energy structure. [0003] For existing wave power generation devices, various power generation methods are adopted, including linear electromagnetic type, pneumatic type, piezoelectric type, electroactive pol...
