[0002] Wave protection at the edges of artificial floating islands is a crucial measure to ensure their stability and safety. Artificial floating islands typically float on water and are affected by waves. In the marine environment, waves pose a serious threat to the stability and structural safety of floating islands. Therefore, effective wave protection measures are necessary to safeguard the floating island structure. Furthermore, waves contain wave impact kinetic energy; if, in addition to achieving the protection objective, this energy is utilized to generate electricity, the goal of full energy utilization can be effectively achieved. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a system for absorbing and converting the kinetic energy of ocean waves impacting the edge of an artificial floating island, so as to achieve the purpose of protection and generate electricity by utilizing the energy in the ocean waves, thereby effectively achieving the purpose of energy utilization.

[0004] Technical Solution: To achieve the above objectives, the present invention provides a system for absorbing and converting the kinetic energy of ocean waves impacting the edge of an artificial floating island. This system includes an artificial floating island on the sea surface, with several wave impact kinetic energy absorption and power generation units arranged in a straight line around its perimeter. Each wave impact kinetic energy absorption and power generation unit includes a non-closed-loop energy-absorbing conveyor belt, a left-rotating power generation pulley, and a right-rotating power generation pulley. The axes of both the left-rotating and right-rotating power generation pulleys are vertically oriented. Both ends of the non-closed-loop energy-absorbing conveyor belt are pulled by elastic components after passing over the sides of the left-rotating and right-rotating power generation pulleys that are far apart from each other. The water surface line of the water area where the artificial floating island is located is at the waist of the non-closed-loop energy-absorbing conveyor belt.

[0005] Furthermore, both the left-hand rotating power generation pulley and the right-hand rotating power generation pulley are cylindrical structures with closed lower ends, and the lower ends of the left-hand rotating power generation pulley and the right-hand rotating power generation pulley are coaxially fixedly connected to the left rotating shaft and the right rotating shaft, respectively.

[0006] Furthermore, the left and right rotating shafts are rotatably mounted on the left and right fixed supports respectively via bearings; both the left and right fixed supports are connected to the periphery of the artificial floating island.

[0007] Furthermore, the inner rings of the cylindrical structures of the left-rotating power generation pulley and the right-rotating power generation pulley are respectively fixedly arranged in a circular array with several left permanent magnet strips and several right permanent magnet strips.

[0008] Furthermore, the left and right rotating generator pulleys are respectively coaxially arranged with a left stator generator coil and a right stator generator coil inside their cylindrical structures; the left stator generator coil and the right stator generator coil are respectively fixedly connected to a left fixed support and a right fixed support through a first stator support and a second stator support.

[0009] Furthermore, a vertical centering spring connecting strip is provided on the rear side of the center position between the left and right rotating power generating pulleys; the non-closed-loop energy-absorbing conveyor belt includes, along its length, a left rear end straightening section, a left cross-winding section, a front energy-absorbing section, a right cross-winding section, and a right rear end straightening section; the left cross-winding section and the right cross-winding section respectively cross over the sides of the left and right rotating power generating pulleys that are far apart from each other; the ends of the left and right rear end straightening sections are respectively fixedly connected to the vertical left and right spring connecting strips, which are symmetrical about both sides of the centering spring connecting strip; the left spring connecting strip and the centering spring connecting strip are elastically connected by several left tension springs; the right spring connecting strip and the centering spring connecting strip are connected by several right tension springs.

[0010] Furthermore, a rearwardly extending guide rod is fixedly connected to the rear side of the centering spring connecting strip. The guide rod is guided and engaged with the guide hole on the fixed structure at the edge of the artificial floating island on the sea surface, so that the centering spring connecting strip will never float or deviate from left or right under the constraint of the guide rod.

[0011] Furthermore, an arc-shaped lateral support is fixedly connected to the front side of the central spring connecting strip, with the concave surface of the arc-shaped lateral support facing the front energy-absorbing section.

[0012] When the front energy-absorbing section is impacted by a sufficiently strong wave from the front, the arc-shaped lateral support bends towards the side convex with the arc-shaped lateral support under the impact of the wave. This causes the convex surface of the middle part of the bent front energy-absorbing section to form a backward pressure on the concave surface of the arc-shaped lateral support, thereby pushing the central spring connecting bar to move backward.

[0013] Beneficial effects: While achieving the purpose of protection, this invention utilizes the energy in the waves to generate electricity, effectively achieving the goal of full energy utilization. At the same time, when encountering high-intensity waves, the excessively bent front energy-absorbing section of this design can more quickly return to its original straight state under the action of several left / right tension springs and the reaction force of the arc-shaped lateral support after the tension is enhanced; thus, it can restore the initial state as much as possible before the second wave arrives, avoiding the problem of not being able to receive the second wave in time.

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

[0019] As attached Figures 1 to 4 The system for absorbing and converting the kinetic energy of wave impact at the edge of the artificial floating island shown includes an artificial floating island on the sea surface. Several wave impact kinetic energy absorption and power generation units 1 are arranged in a row around the periphery of the artificial floating island. Each wave impact kinetic energy absorption and power generation unit 1 includes a non-closed-loop energy-absorbing conveyor belt 5, a left-rotating power generation pulley 10a, and a right-rotating power generation pulley 10b. The axes of the left-rotating power generation pulley 10a and the right-rotating power generation pulley 10b are both vertically oriented. The non-closed-loop energy-absorbing conveyor belt 5 is made of 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 resistant to ultraviolet aging; it is flexible in design and can be customized with multi-layer structures (such as a core layer with tensile strength and a surface layer with wear resistance). The height of the non-closed-loop energy-absorbing conveyor belt 5 is approximately 1.5m.

[0020] Both ends of the non-closed-loop energy-absorbing conveyor belt 5 are pulled by elastic components after passing over the sides of the left rotating power generation pulley 10a and the right rotating power generation pulley 10b, which are far apart from each other; the water surface line 4 of the water area where the artificial floating island is located is at the waist of the non-closed-loop energy-absorbing conveyor belt 5.

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

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

[0023] The inner rings of the cylindrical structures of the left rotating power generation pulley 10a and the right rotating power generation pulley 10b are respectively arranged in a circular array with several left permanent magnet strips 11a and several right permanent magnet strips 11b.

[0024] The left stator generating coil 9a and the right stator generating coil 9b are coaxially arranged inside the cylindrical structure of the left rotating generating pulley 10a and the right rotating generating pulley 10b, respectively; the left stator generating coil 9a and the right stator generating 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] A vertically centered spring connecting strip 3 is provided on the rear side of the center position between the left rotating power generation pulley 10a and the right rotating power generation pulley 10b; the non-closed-loop energy-absorbing conveyor belt 5 includes, along its length, a left rear end straightening section 5.1, a left cross-winding section 5.2, a front energy-absorbing section 5.3, a right cross-winding section 5.4, and a right rear end straightening section 5.5; the left cross-winding section 5.2 and the right cross-winding section 5.4 respectively cross over the sides of the left rotating power generation pulley 10a and the right rotating power generation pulley 10b that are far apart from each other; the ends of the left rear end straightening section 5.1 and the right rear end straightening section 5.5 are... The left spring connecting strip 6a and the right spring connecting strip 6b are fixedly connected vertically, and the left spring connecting strip 6a and the right spring connecting strip 6b are symmetrical to the two sides of the central spring connecting strip 3; the left spring connecting strip 6a and the central spring connecting strip 3 are elastically connected by a number of left tension springs 7a; the right spring connecting strip 6b and the central spring connecting strip 3 are connected by a number of right tension springs 7b; the left tension springs 7a and the right tension springs 7b are corrosion-resistant 316 stainless steel springs, precipitation hardening stainless steel (17-7PH) or nickel-based alloys (Inconel 718).

[0026] A rearwardly extending guide rod 71 is fixedly connected to the rear side of the centering spring connecting strip 3. The guide rod 71 is guided and engaged with the guide hole on the fixed structure at the edge of the artificial floating island on the sea surface, so that the centering spring connecting strip 3 will never float or deviate from left or right under the constraint of the guide rod 71.

[0027] The front side of the central spring connecting bar 3 is fixedly connected to an arc-shaped lateral support 2, with the concave surface of the arc-shaped lateral support 2 facing the front energy-absorbing section 5.3. When the front energy-absorbing section 5.3 is impacted by a sufficiently strong wave from the front, the arc-shaped lateral support 2 bends towards the side convex to the arc-shaped lateral support 2 under the impact of the wave. This causes the convex surface of the middle part of the bent front energy-absorbing section 5.3 to form a backward pressure on the concave surface of the arc-shaped lateral support 2, thereby pushing the central spring connecting bar 3 to move backward.

[0028] Working principle:

[0029] When the wind is calm, attach Figure 4 As shown in the figure above, from a top-down perspective, the front energy-absorbing section 5.3 of the non-closed-loop energy-absorbing conveyor belt 5 is in a straight, taut state under the combined pull of several left tension springs 7a and several right tension springs 7b.

[0030] Ocean waves are classified into normal intensity waves and high intensity waves;

[0031] When the waves are of moderate intensity, when the first wave 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 convex arc-shaped support 2 under the impact of the first wave, absorbing the impact kinetic energy of the wave. This causes the front energy-absorbing section 5.3 to lengthen, thus preventing the edge of the artificial floating island from being directly impacted by the waves. Since the total length of the non-closed-loop energy-absorbing conveyor belt 5 remains constant, during the process of the front energy-absorbing section 5.3 bending and lengthening towards the convex arc-shaped support 2, the left cross-winding section 5.2, the right cross-winding section 5.4, the left rear end straightening section 5.1, and the right rear end straightening section 5.5 all adaptively perform linear movements, and the left rear end straightening section 5.1 and the right rear end straightening section 5.5 adapt accordingly. As the elasticity shortens, several left tension springs 7a and several right tension springs 7b are further stretched and store elastic potential energy. During the above process, the linear motion of the left cross-winding section 5.2 and the right cross-winding section 5.4 will drive the left rotating generator pulley 10a and the right rotating generator pulley 10b to rotate along their respective axes under the action of rolling friction. This causes several left permanent magnet strips 11a and several right permanent magnet strips 11b in the left rotating generator pulley 10a and the right rotating generator pulley 10b to rotate around the left stator generator coil 9a and the right stator generator coil 9b, respectively. This causes the left stator generator coil 9a and the right stator generator coil 9b to generate induced current and generate electricity. The energy conversion path of this process is to convert the kinetic energy of the wave impact into elastic potential energy and electrical energy, respectively.

[0032] Since the waves are of average intensity, the front energy-absorbing section 5.3 does not bend enough to contact the convex arc-shaped side support 2 under the impact of the first wave. After the first wave ends, the front energy-absorbing section 5.3 straightens again under the combined pull of several left tension springs 7a and several right tension springs 7b, returning to its initial state and waiting to receive the second wave. 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 influence of linear motion and generate electricity. The energy conversion path at this time is to convert the elastic potential energy stored in a section of several left tension springs 7a and several right tension springs 7b into electrical energy.

[0033] When the waves are high-intensity, the front energy-absorbing section 5.3 of the non-closed-loop energy-absorbing conveyor belt 5 may bend excessively towards the convex arc side towards the support 2 under the impact of high-intensity waves. This results in an excessively long time required for the front energy-absorbing section 5.3 to return to a straight state after excessive bending. Consequently, when the second wave arrives, the front energy-absorbing section 5.3, which has been excessively bent by the first wave, has not yet fully returned to a straight state, thus weakening the energy conversion efficiency of the front energy-absorbing section 5.3 and affecting the power generation cycle. This solution effectively solves this problem, and the working principle of its core structure is as follows:

[0034] When the first high-intensity wave 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 convex arc-shaped support 2 under the impact of the first high-intensity wave and absorbs the impact kinetic energy of the wave. At this time, the front energy-absorbing section 5.3 bends towards the convex arc-shaped support 2 under the impact of the first high-intensity wave, and the middle convex surface adheres to and pushes backward against the arc-shaped support 2, thereby causing the arc-shaped support 2 to shift backward, as shown. Figure 4 As shown in the bottom diagram, the rearward shift of the arc-shaped lateral support 2 causes several left tension springs 7a and several right tension springs 7b to become oblique, and further lengthen due to the oblique shift, thereby further enhancing the pull force of the left tension springs 7a and several right tension springs 7b; at the same time, after the rearward shift of the arc-shaped lateral support 2, under the action of the oblique left tension springs 7a and right tension springs 7b, a reaction force is formed on the central convex surface of the excessively bent front energy-absorbing section 53, and its reaction force effectively inhibits the further bending of the excessively bent front energy-absorbing section 53; at the same time, under the induction of the several left tension springs 7a / right tension springs 7b after the enhanced tension and the reaction force of the arc-shaped lateral support 2, the excessively bent front energy-absorbing section 53 can more quickly return to its original straight state; thus, it can restore to its initial state as much as possible before the arrival of the second wave, avoiding the problem of not being able to receive the second wave in time.

[0035] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
