Therefore, effective wave protection measures are needed to protect the floating island structure. At the same time, wave impact kinetic energy is contained in waves. If the energy in waves can be used to generate electricity on the basis of achieving the protection purpose, the purpose of full utilization of energy can be effectively achieved.

[0005] Further, both the left rotary power generation pulley and the right rotary power generation pulley are cylindrical structures with closed lower ends, and the lower ends of the left rotary power generation pulley and the right rotary power generation pulley are respectively coaxially fixedly connected with a left rotating shaft and a right rotating shaft.

[0006] Further, the left rotating shaft and the right rotating shaft are respectively rotatably installed on a left fixed support and a right fixed support through bearings; both the left fixed support and the right fixed support are connected to the periphery of the artificial floating island.

[0007] Further, a number of left permanent magnetic strips and a number of right permanent magnetic strips are respectively fixedly arranged in a circumferential array on the inner circles of the cylindrical structures of the left rotary power generation pulley and the right rotary power generation pulley.

[0008] Furthermore, a left stator generating coil and a right stator generating coil are coaxially arranged inside the cylindrical structure of the left rotating generating pulley and the right rotating generating pulley respectively; the left stator generating coil and the right stator generating coil are fixedly connected to the left fixed support and the right fixed support respectively through the first stator support and the second stator support.

[0009] Furthermore, a vertical center spring connecting strip is arranged on the rear side of the center position between the left-rotating power generation pulley and the right-rotating power generation pulley; the non-closed-loop energy absorption conveyor belt includes a left rear end straightening section, a left spanning section, a front energy absorption section, a right spanning section and a right rear end straightening section in sequence along the length direction; the left spanning section and the right spanning section respectively span the sides of the left-rotating power generation pulley and the right-rotating power generation pulley that are away from each other; the end of the left rear end straightening section and the end of the right rear end straightening section are respectively fixedly connected to the vertical left spring connecting strip and the right spring connecting strip, and the left spring connecting strip and the right spring connecting strip are symmetrical to both sides of the center spring connecting strip; the left spring connecting strip and the center spring connecting strip are elastically connected by a plurality of left pulling springs; the right spring connecting strip and the center spring connecting strip are pulled by a plurality of right pulling springs.

[0012] When the front energy absorbing section is impacted by sufficiently strong waves from the front, the arc-shaped lateral support bends toward the convex side of the arc-shaped lateral support under the impact of the waves, so that the convex surface of the middle part of the bent front energy absorbing section forms a backward top pressure on the concave surface of the arc-shaped lateral support, thereby pushing the center spring connecting strip to move backward.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] As shown in the attached Figures 1 to 4 The wave impact kinetic energy absorption and energy conversion and utilization system at the edge of the artificial floating island shown in the figure includes an artificial floating island on the sea surface, and a number of wave impact kinetic energy absorption and power generation units 1 arranged in a row are provided on the periphery of the artificial floating island; the wave impact kinetic energy absorption and power generation unit 1 includes a non-closed-loop energy absorption conveyor belt 5, a left rotating power generation pulley 10a and a right rotating power generation pulley 10b, and the axes of the left rotating power generation pulley 10a and the right rotating power generation pulley 10b are both vertically arranged; the non-closed-loop energy absorption conveyor belt 5 is a fiber-reinforced polymer (FRP), glass fiber (GFRP), carbon fiber (CFRP) or basalt fiber-reinforced epoxy / vinyl resin matrix; it has a high strength-to-weight ratio (superior to steel); it is completely immune to seawater corrosion and anti-ultraviolet aging; the design is flexible and a multi-layer structure can be customized (such as a tensile core layer and a wear-resistant surface layer), and the height of the non-closed-loop energy absorption conveyor belt 5 is about 1.5 m.

[0020] Both ends of the non-closed-loop energy absorption conveyor belt 5 respectively bypass the far sides of the left rotating power generation pulley 10a and the right rotating power generation pulley 10b and are both pulled by elastic members; the water line 4 of the water area where the artificial floating island is located is at the waist of the non-closed-loop energy absorption conveyor belt 5.

[0021] Both the left rotating power generation pulley 10a and the right rotating power generation pulley 10b are cylindrical structures with closed lower ends, and the lower ends of the left rotating power generation pulley 10a and the right rotating power generation pulley 10b are respectively coaxially and fixedly connected with a left rotating shaft 19a and a right rotating shaft 19b.

[0022] The left rotating shaft 19a and the right rotating shaft 19b are respectively rotatably installed on the left fixed support 12a and the right fixed support 12b through bearings; the left fixed support 12a and the right fixed support 12b are both connected to the periphery of the artificial floating island.

[0023] A number of left permanent magnetic strips 11a and a number of right permanent magnetic strips 11b are respectively fixedly arranged in a circumferential array on the inner circles of the cylindrical structures of the left rotating power generation pulley 10a and the right rotating power generation pulley 10b.

[0024] Inside the cylinder structures of the left-rotating power generation pulley 10a and the right-rotating power generation pulley 10b, a left stator power generation coil 9a and a right stator power generation coil 9b are coaxially arranged respectively; the left stator power generation coil 9a and the right stator power generation coil 9b are fixedly connected to the left fixed support 12a and the right fixed support 12b through the first stator support 8a and the second stator support 8b respectively.

[0025] At the rear side of the middle position between the left-rotating power generation pulley 10a and the right-rotating power generation pulley 10b, a vertical middle spring connecting bar 3 is provided; the non-closed-loop energy-absorbing conveyor belt 5 sequentially includes a left rear end straightening section 5.1, a left winding section 5.2, a front energy-absorbing section 5.3, a right winding section 5.4, and a right rear end straightening section 5.5 along the length direction; the left winding section 5.2 and the right winding section 5.4 respectively wind around the sides of the left-rotating power generation pulley 10a and the right-rotating power generation pulley 10b that are far away from each other; the ends of the left rear end straightening section 5.1 and the right rear end straightening section 5.5 are respectively fixedly connected to the vertical left spring connecting bar 6a and the right spring connecting bar 6b, and the left spring connecting bar 6a and the right spring connecting bar 6b are symmetric on both sides of the middle spring connecting bar 3; the left spring connecting bar 6a and the middle spring connecting bar 3 are elastically pulled and connected through a plurality of left pulling springs 7a; the right spring connecting bar 6b and the middle spring connecting bar 3 are pulled and connected through a plurality of right pulling springs 7b; the left pulling springs 7a and the right pulling springs 7b are 316 stainless steel springs, precipitation hardening stainless steel (17-7PH), or nickel-based alloy (Inconel718) that are corrosion-resistant.

[0026] A guide rod 71 extending backward is fixedly connected to the rear side of the middle spring connecting bar 3, and the guide rod 71 is in guiding fit with the guide hole on the fixed structure at the edge of the artificial floating island on the sea surface, so that the middle spring connecting bar 3 is always constrained by the guide rod 71 and will not float or shift left and right.

[0027] An arc-shaped side support 2 is fixedly connected to the front side of the middle spring connecting bar 3, and the concave surface of the arc-shaped side support 2 faces the front energy-absorbing section 5.3; when the front energy-absorbing section 5.3 is impacted by a strong enough sea wave from the front, the arc-shaped side support 2 bends toward the side convex to the arc-shaped side support 2 under the impact of the sea wave, so that the convex surface in the middle of the bent front energy-absorbing section 5.3 forms a backward pressing force on the concave surface of the arc-shaped side support 2, thereby pushing the middle spring connecting bar 3 to move backward.

[0028] Working principle:

[0029] When the sea is calm, Figure 4 As shown in the upper figure above, in the top view perspective, the front energy-absorbing section 5.3 of the non-closed-loop energy-absorbing conveyor belt 5 is in a straight and taut state under the combined pulling of a plurality of left pulling springs 7a and a plurality of right pulling springs 7b;

[0030] The sea waves are divided into sea waves of general intensity and high-intensity sea waves;

[0031] When the sea waves are of general intensity, when the first wave of sea waves impacts the front energy-absorbing section 5.3 of the non-closed-loop energy-absorbing conveyor belt 5, the front energy-absorbing section 5.3 bends towards the side of the convex arc-shaped side support 2 under the impact of the first wave of sea waves and absorbs the impact kinetic energy of the sea waves, thereby making the front energy-absorbing section 5.3 longer, and further avoiding the direct impact of the sea waves on the edge of the artificial floating island; Since the total length of the non-closed-loop energy-absorbing conveyor belt 5 is constant, during the process that the front energy-absorbing section 5.3 bends and becomes longer towards the side of the convex arc-shaped side support 2, the left bypass section 5.2, the right bypass section 5.4, the left rear end straightening section 5.1 and the right rear end straightening section 5.5 all adaptively perform linear motion, and make the left rear end straightening section 5.1 and the right rear end straightening section 5.5 adaptively become shorter, and a number of left pulling springs 7a and a number of right pulling springs 7b are further stretched to store elastic potential energy; During the above process, the linear motion of the left bypass section 5.2 and the right bypass section 5.4 will drive the left rotating power generation pulley 10a and the right rotating power generation pulley 10b to rotate along their respective axes under the action of rolling friction, so that a number of left permanent magnetic strips 11a and a number of right permanent magnetic strips 11b in the left rotating power generation pulley 10a and the right rotating power generation pulley 10b respectively rotate around the left stator power generation coil 9a and the right stator power generation coil 9b, and further make the left stator power generation coil 9a and the right stator power generation coil 9b generate induced current and generate electricity. The energy conversion path of this process is to convert the impact kinetic energy of the sea waves into elastic potential energy and electrical energy respectively.

[0032] Since the sea waves are of general intensity, the bending degree of the front energy-absorbing section 5.3 towards the side of the convex arc-shaped side support 2 under the impact of the first wave of sea waves is not enough to contact the arc-shaped side support 2. When the impact of the first wave of sea waves ends, the front energy-absorbing section 5.3 is re-straightened into a straight line under the joint pulling of a number of left pulling springs 7a and a number of right pulling springs 7b and returns to the initial state, waiting to meet the second wave of sea waves. During the process of returning to the initial state, the left rotating power generation pulley 10a and the right rotating power generation pulley 10b will also rotate once under the drive of the linear motion and generate electricity. The energy conversion path at this time is to finally convert the elastic potential energy stored in a section of a number of left pulling springs 7a and a number of right pulling springs 7b into electrical energy.

[0033] When the sea waves are high-intensity sea waves, the front energy-absorbing section 5.3 of the non-closed-loop energy-absorbing conveyor belt 5 may bend too much towards the convex arc-shaped side support 2 under the impact of the high-intensity sea waves, resulting in too long a time required for the front energy-absorbing section 5.3 after excessive bending to return to a straight state. Furthermore, when the second wave of sea waves comes, because the front energy-absorbing section 5.3 after being impacted by the first wave of sea waves and excessively bent has not completely returned to a straight state, it will lead to a reduction in the energy conversion efficiency of the front energy-absorbing section 5.3 and also affect the power generation rhythm. However, this problem is effectively solved in this solution, and the working principle of the core structure for solving this problem is as follows:

[0034] When the first wave of high-intensity sea waves impacts the front energy-absorbing section 5.3 of the non-closed-loop energy-absorbing conveyor belt 5, the front energy-absorbing section 5.3 bends towards the side of the convex arc-shaped side support 2 under the impact of the first wave of high-intensity sea waves and absorbs the impact kinetic energy of the sea waves. At this time, the front energy-absorbing section 5.3 bends towards the side of the convex arc-shaped side support 2 under the impact of the first wave of high-intensity sea waves, and the middle convex surface fits and presses backward against the arc-shaped side support 2, thereby causing the arc-shaped side support 2 to shift backward, as Figure 4 shown in the bottommost figure below. The backward shift of the arc-shaped side support 2 makes several left pulling springs 7a and several right pulling springs 7b inclined and further elongated due to the inclination, thereby further enhancing the pulling-back force of the left pulling springs 7a and several right pulling springs 7b; at the same time, after the backward shift of the arc-shaped side support 2, a reaction force is formed on the middle convex surface of the excessively bent front energy-absorbing section 5.3 under the action of the inclined left pulling springs 7a and right pulling springs 7b, and this reaction force effectively inhibits the further bending of the excessively bent front energy-absorbing section 5.3; at the same time, the excessively bent front energy-absorbing section 5.3 can return to its original straight state faster under the driving action of several left pulling springs 7a / right pulling springs 7b with enhanced pulling force and the reaction force of the arc-shaped side support 2; thus, it can, to the greatest extent, return to the initial state as much as possible before the second wave of sea waves arrives, avoiding the problem of being unable to receive the second wave of sea waves in time.

[0035] The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
