Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] A power measurement device for an oscillating buoy type wave energy generation system provided by the present invention, the axonometric view and top view of its effect after installation are respectively figure 1 and figure 2 As shown, the specific composition is as image 3 As shown, by the motion transmission part of Figure 4(a), Figure 4(b) and Figure 5 The energy trapping moiety (PTO) composition. The motion transmission part includes an inverted U-shaped frame 3, a tension-pressure sensor 5, a double-sided rack 6, a connecting shaft 10, and a rotating shaft 14. The U-shaped frame 3 fixed on the outer float 2 is connected to the tension-pressure sensor 5 through the connecting shaft 10. The latter other end is connected with double-sided rack by rotating shaft 14 . That is to say, the bottom end of the inverted U-sha...

The invention provides a power measuring device of an oscillating float type wave energy power generation system. The power measuring device is formed by a movement transmission part and an energy capture part (PTO), wherein the movement transmission part comprises a U-shaped frame, a tension-compression sensor, a two-sided rack and a connecting shaft; and the energy capture part comprises a square frame, a rotation angle sensor, a rack drive mechanism, a direct-current generator and a bearing and a bearing block. During work, movement produced by the floater under the action of wave is transmitted to the PTO system by the movement transmission part, thereby recording date by the sensor. The power measuring device disclosed by the invention is mainly used for solving the problem of power measurement in testing of the oscillating float type wave energy power generation device, can effectively measure the output power of a model, and can intuitively display a power generation effect. The power measuring device is simple in structure form, low in cost, good in stability, reliable in measurement result, and capable of simulating the movement and power effects of the model under different PTO damping.
Description
technical field [0001] The invention relates to a power measuring device, in particular to a power measuring device of an oscillating float type wave energy generation system, belonging to the field of development and utilization of renewable energy. Background technique [0002] In recent years, the global energy supply and demand have become increasingly tense, and environmental protection and CO 2 The call for emission reduction is getting higher and higher, which greatly promotes the development and utilization of clean energy. Wave energy is a kind of clean energy, and its conversion technology has also been greatly developed. Many different types of wave energy generation devices have been proposed, among which the oscillating float type wave energy generation system is a research hotspot. [0003] In 2008, the Oregon State University of the United States proposed a heave wave power generation device named L-10. The device consists of a cylindrical buoy with a deep dr...
