Example Embodiment

[0023] Example 1:

[0024] Such as figure 1 As shown, the floating platform 2 is fixed by the anchor chain 4, and the other end of the anchor chain 4 is fixed to the seabed by the high holding power anchor 3; the conical floating body 1 is distributed on the floating platform 2. When there is no wave action, the floating body 1 is buoyant. The effect is vertical upwards; the bottom of each floating body is connected to the power transmission cable 5, which is laid on the floating platform, and finally assembled into a general cable to supply power to offshore facilities.

[0025] Such as figure 2 As shown, the conical floating body 1 and the floating platform 2 are connected by an anchor chain connecting ring 8; both the floating body 1 and the floating platform 2 are located below the average sea level, and the top surface of the floating body is slightly lower than the sea level; the top of the floating body 1 An annular channel 7 is set, and induction coils 6 are arranged aroun...

Example Embodiment

[0029] Example 2:

[0030] See figure 1 with Figure 4 The only difference from Embodiment 1 is that the upper plane of the floating platform 2 is a trapezoid, the number of conical floating bodies 1 is larger, and a distribution method favorable to the absorption and conversion of wave energy is adopted for the main incoming wave directions.

Example Embodiment

[0031] Example 3:

[0032] See figure 1 with Figure 5 The only difference from Embodiment 1 is that the floating body used is a T-shaped floating body 11.

Abstract

The utility model belongs to the field of regenerative energy technologies and ocean facilities, and particularly relates to a point absorption type wave energy power generation device based on a floating platform. The point absorption type wave energy power generation device comprises the floating platform, floating bodies, anchor chains, cables and high holding power anchors, wherein the floating platform is connected with the high holding power anchors through the anchor chains so as to be fixed; the floating bodies are connected with the platform through the shorter anchor chains; the cables are fixedly arranged on the surface of the platform; the point absorption type wave energy power generation device is characterized in that the connection anchor chains between the floating bodies and the floating platform can be always kept in a tensioning state as the individual floatage of each of the floating bodies is large enough; when the floating bodies swing under the action of waves, magnets and coils in the floating bodies can relatively move along with the movement of the floating bodies, and magnetic fluxes in the coils are changed, so that induced electromotive force is generated and supplies power. The point absorption type wave energy power generation device based on the floating platform is simple in design form and suitable for deep water regions, adapts to incoming waves from all the directions, is higher in energy conversion efficiency, stable in energy output, high in safety and convenient to mount and move and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of novel renewable energy technology and marine equipment, in particular to a point-absorption wave energy generating device based on a floating platform. Background technique [0002] With the intensification of the global energy crisis, the development of ocean wave energy has been paid more and more attention. A large number of different forms of wave energy devices have been developed, which can be divided into three types: offshore type, near-shore type and coastal type according to the location of the device. At present, most of the designs that have been researched and widely used are nearshore and coastal, such as oscillating water column wave energy devices, pendulum wave energy devices, and polywave reservoir wave energy devices. Nearshore and onshore installations are widely favored by researchers due to their proximity to the mainland, low installation and maintenance costs, and easy connection to the gri...
