By adopting the above scheme, the floating member 500 is a hollow barrel body, so that the floating member 500 has a better floating force on the sea surface, thereby being capable of floating on the sea surface better. The barrel wall 520 of the floating piece 500 is cylindrical, so that the peripheral surface of the floating piece 500 is arc-shaped, and when seawater passes along the peripheral surface of the floating piece, the arc-shaped surface of the peripheral surface of the floating piece 500 can reduce the impact force of the seawater, thereby improving the stability of the floating piece 500 at a set position and ensuring the power generation stability of the device; the bottom wall 510 of the buoyant member 500 is hemispherical, so that the vertical impact of the sea wave can be reduced, and the damage of the sea to the buoyant member 500 can be reduced.

In some embodiments, the top of the float 500 is provided with a collision alarm to prevent a passing ship from hitting the wave power plant.

According to the present invention, a flat floating structure 100 is disclosed, referring to fig. 2 and 3, for bearing a power generation assembly 200, which includes the above three floating members 500, namely, a first floating member 121, a second floating member 122 and a third floating member 123, and the three floating members 500 can be defined as a flat floating assembly 120; the rigid member 110 is fixedly disposed between the first floating member 121, the second floating member 122 and the third floating member 123.

Specifically, the floating member 500 is adopted in the flat floating structure 100, and the stability of the floating member 500 is high, so that the flat floating structure 100 is stabilized at a certain position on the sea surface, and the power generation device on the flat floating structure 100 can generate power stably and efficiently.

Furthermore, the first floating member 121, the second floating member 122 and the third floating member 123 may be arranged in a triangular shape, thereby further improving the stability of the floating structure 100.

In some embodiments, the floating structure 100 further comprises an anchor assembly 400, the anchor assembly 400 comprising an anchor line 420 and an anchor head 410, the anchor line 420 being fixedly connected to the buoyant member 500 or the rigid member 110, the anchor head 410 being fixedly connected to the anchor line 420 and being adapted to be submerged into the sea floor; accordingly, the flat floating structure 100 is floated at a certain position on the sea surface by the arrangement of the anchor assembly 400, thereby stabilizing the power generation of the wave power generating device.

To further improve the stability of the floating structure 100, in some embodiments, the anchor assembly 400 further includes a buffer 430, the buffer 430 floats on the water surface, the buffer 430 is connected to the anchor line 420 and has a bearing effect on the anchor line 420, and the buffer 430 is located at a position where the anchor line 420 is close to the floating structure 100. When the anchor cables 420 are stressed, the anchor cables 420 act on the buffer member 430 instead of acting on the floating structure 100, thereby further ensuring the stability of the floating structure 100.

Further, the plurality of buffering members 130 are provided, and the plurality of buffering members 430 are arranged at intervals along the length direction of the anchor cable 420, so that the stability of the floating structure 100 is further improved.

In some embodiments, the power generation assembly 200 is mounted to the third rigid bar 113, i.e., the aft portion of the flat floating structure 100 being heavier and the head portion of the flat floating structure 100 being lighter. At this time, the anchor assembly 400 is fixedly connected to the second floating member 122, i.e., the head of the floating structure 100 is balanced with the tail of the floating structure 100, and the anchor assembly 400 can preferably fix the floating structure 100 at a set position on the sea surface, so that the power generation assembly 200 is located at a corresponding position on the sea surface, thereby ensuring that the device can generate power stably.

It should be noted that, the floating structure 100 is designed into a triangular structure, the power generation assembly 200 is fixedly arranged on the third rigid rod 113, and the anchor assembly 400 is fixedly arranged on the second floating member 122; thus, when the floating structure 100 faces waves, and the waves flow from the second floating member 122 to the third rigid rod 113, the first floating member 121, the second floating member 122, and the third floating member 123 can reduce the slapping force of the waves to a certain extent, and improve the stability of the floating structure 100.

Further, referring to fig. 1 and 3, the first rigid bar 111 and the second rigid bar 112 have the same length, and the middle portion of the third rigid bar 113 in the length direction is provided with a mounting position for mounting the power generation assembly 200, so that the floating structure 100 is in the shape of an isosceles triangle, and the power generation assembly 200 is mounted in the middle of the bottom side of the isosceles triangle. Thus, waves flow from the second floating member 122 to the third rigid rod 113, and the first floating member 121, the second floating member 122 and the third floating member 123 weaken the slapping force of the waves to the greatest extent, thereby improving the stability of the floating structure 100.

In some embodiments, the first floating member 121 and the third floating member 123 are the same size, and the second floating member 122 is smaller than the first floating member 121. By adopting such a design, firstly, the manufacturing cost of the second floating member 122 is reduced; secondly, the head of the floating structure 100 has a slapping force which can weaken the seawater better; third, anchor assembly 400 can preferably stabilize second float 122.

In some embodiments, the distance between the second floating member 122 and the third rigid rod 113 is greater than one wavelength of the wave, and by adopting the above-mentioned structural design, the wave passes through the third rigid rod 113 from the second floating member 122, and the length of the floating structure 100 can cover a long distance of a double wave, so that the floating structure 100 has less up-and-down floating and higher stability.

in some embodiments, the floating member 500, the power generation assembly 200 and the second floating member 122 are on the same plane, so that when a wave flows through the second floating member 122, the power generation assembly 200 and the floating member 500, the wave can preferably push the floating member 500 to float up and down while ensuring that the flat floating structure 100 can preferably attenuate the slapping force of the sea water.

In some embodiments, the distance between the float 500 and the floating structure 100 is about half-wave long, so that when a wave passes through the floating structure 100 and the float 500, the float 500 can reach the trough at a certain moment, the floating structure 100 can reach the crest or the opposite, thereby realizing the maximum angular rotation of the swing arm 310, and preferably providing mechanical energy to the power generation assembly 200.
