Embodiment Construction

[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0025] A round hole is opened in the middle of the streamlined diversion box 2, and the stake 15 is fixed in the round hole. Five small-diameter but high-strength steel members are used to connect the water-retaining outer plate 1 and the diversion box 2, and the positional relationship between the two should satisfy that the reserved width of the water channel remains basically unchanged after the middle section of the box. Cylindrical float 3 is fixed on the rear of the casing through slidable slide rail 4, and reserves a certain distance from the side wall. Several rows of bearings are arranged on the top and around the pile 15 to ensure that the box can rotate freely along the pile 15. The piles 15 are pre-buried under the seabed.

[0026] The high-strength nylon rope 7 is connected directly below the float 3, passes through the waterproof...

Abstract

The invention belongs to the technical field of ocean energy utilization, and provides a wave direction self-adaptive multi-water-channel wave focusing type wave energy power generation device. The wave direction self-adaptive multi-water-channel wave focusing type wave energy power generation device comprises an energy collecting system, an energy conversion system and a supporting system. Wavesare focused through double water channels, and the motion wave amplitude of water mass points behind a box body is doubled. A device and a fixed pile column are connected through a universal bearing,an opening of the device always faces the flowing direction of the waves, and the device adapts to different seasons and water area conditions, is low in requirement for the environment and can be putinto use in a wide sea area. A plurality of circles of pre-stretching spring pressing pieces are arranged in a winding barrel, it is guaranteed that no matter a floater is positioned at the wave crest or the wave trough, a nylon rope connected with the floater is always in a straightened state, and the situation that due to loosening, the rope is derailed to a pulley block, and consequently normal work cannot be achieved is avoided. A pawl is fixed to a fixed connection gear connected with a ratchet wheel, so that only rotation in one direction in the two-way rotation of the winding barrel drives the ratchet wheel to operate, accordingly, one-way energy storage of a flywheel rotor in a power generation cabin is determined, and meanwhile the kinetic energy upper limit of a flywheel is limited.

Description

technical field [0001] The invention belongs to the technical field of ocean energy utilization, in particular to a wave energy generating device based on the principles of wave focusing and wave direction self-adaptation. Background technique [0002] The ocean contains considerable energy. The full development and utilization of marine energy can effectively fill the current energy gap in the world. Among many forms of ocean energy, wave energy has attracted extensive attention due to its advantages of being independent of time and place and widely distributed, and has shown good application potential. However, although wave energy resources are widely distributed in many sea areas around the world, their density is uneven and fluctuates greatly with seasons, resulting in low wave energy utilization efficiency of traditional wave energy devices. The present invention proposes a wave energy power generation device for medium and low wave energy density sea areas. The devi...
