This device absorbs and disperses the kinetic energy of water currents, suppressing the tendency of the floating island to shift due to wave action and reducing noise levels, significantly improving living comfort. Notably, converting the unabsorbed residual kinetic energy into electricity can not only extend the lifespan of the floating city's infrastructure but also enhance ecological benefits through green energy conversion technology, providing innovative technological support for the sustainable development of future maritime communities. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a periodic surge energy absorption and utilization system for floating cities at sea, so as to achieve the purpose of repeatedly absorbing and utilizing the kinetic energy of ocean wave crests.

[0004] Technical solution: To achieve the above objectives, the present invention provides a periodic surge energy absorption and utilization system for a floating city at sea, wherein the surge energy absorption and utilization system is composed of several wave energy absorption and power generation units arranged in parallel and at equal intervals.

[0005] At any wave energy-absorbing power generation unit, the direction away from the artificial floating city is marked as the front. The wave energy-absorbing power generation unit includes a horizontal fixed support, and the power generation unit is connected and installed at the lower front of the fixed support through an oblique arm.

[0006] The power generation unit includes a power generation stator and a power generation rotor. The axes of the power generation stator and the power generation rotor are horizontal and perpendicular to the front-back direction. The cylindrical power generation rotor rotates coaxially outside the power generation stator. An induction coil is installed on the power generation stator, and a permanent magnet is installed on the inner wall of the power generation rotor. The end of the inclined arm is fixed to one end of the power generation stator, and the lower end of the cylindrical power generation rotor is level with the sea surface in a calm state.

[0007] Furthermore, a layer of arc-shaped wound fabric tape is attached to the outer wall of the cylindrical generator rotor, and the clockwise end of the arc-shaped wound fabric tape is fixedly connected to the outer wall of the generator rotor by a connecting strip.

[0008] The counterclockwise end of the arc-shaped wound fabric strip is tangentially connected to a water-adhering fabric strip extending horizontally backward. The rear end of the water-adhering fabric strip is fixedly connected to a structural strip along the contour. Both ends of the structural strip are fixedly connected to two guide rods extending horizontally backward. The rear ends of the two guide rods are vertically connected to a horizontal translation axis. An upper wave-facing plate extending obliquely upward and a lower wave-facing plate extending obliquely downward are connected to the translation axis.

[0009] Furthermore, a pair of downwardly extending guide seat brackets are fixedly connected to the fixed bracket, and a guide seat corresponding to the guide rod is fixedly connected to the lower end of each guide seat bracket. The two guide rods pass through the guide holes on the corresponding guide seats along the length direction; the translation shaft is initially attached to the rear side of the two pairs of guide seats.

[0010] Furthermore, the other end of the generator stator is fixedly connected to a fixed disk via a fixed shaft, and the fixed disk is connected to the generator rotor via a torsion spring; the torsion spring applies a clockwise elastic torque to the generator rotor, thereby making the water-adhesive cloth belt taut in the initial state.

[0011] Furthermore, a pair of first bearing seats are provided at the root of the lower wave-facing plate. The first bearing seats are coaxially damped with the translation shaft through one-way damping bearings. The one-way damping bearings generate damping when the lower wave-facing plate swings downward around the translation shaft, and there is no damping when the lower wave-facing plate swings upward around the translation shaft. A torsion spring b is coaxially installed at one end of the translation shaft. The torsion spring b applies a clockwise torque to the first bearing seats, so that the lower wave-facing plate always tends to swing downward under the action of torque. A lower limit seat is integrally provided on the lower side of the middle of the translation shaft. Under the action of the torsion spring b, the front side of the lower wave-facing plate is limited to abut against the lower limit seat, so that the lower wave-facing plate cannot swing downward further.

[0012] Furthermore, a pair of second bearing seats are provided at the root of the upper wave-facing plate. The second bearing seats are coaxially damped with the translation shaft through one-way damping bearings. The one-way damping bearings generate damping when the upper wave-facing plate swings upward around the translation shaft, and there is no damping when the upper wave-facing plate swings downward around the translation shaft. A C-torsion spring is coaxially installed at the other end of the translation shaft. The C-torsion spring applies a counterclockwise torque to the second bearing seats, so that the upper wave-facing plate always tends to swing upward under the action of torque. An upper limit seat is integrally provided on the upper side of the middle part of the translation shaft. Under the action of the C-torsion spring, the front side of the upper wave-facing plate is limited to abut against the upper limit seat, so that the upper wave-facing plate cannot swing upward further.

[0013] Furthermore, the water-coated fabric strip is at the same height as the sea surface in a calm state.

[0014] Furthermore, it also includes artificial floating cities floating on the sea surface, with surge energy utilization systems located at a certain distance from the outer edge of the artificial floating city, and fixed supports fixed to the artificial floating city or connected through a height-adjustable structure.

[0015] Beneficial effects: In each of the four stages of this invention, the power generation rotor rotates once, causing the induction coils on the power generation stator to generate four induced currents, thereby achieving the purpose of repeatedly absorbing and utilizing the kinetic energy of ocean wave crests; realizing the functional integration of protective facilities and renewable energy devices. This composite solution not only extends the service life of marine city infrastructure, but also enhances ecological benefits through green energy conversion technology, providing innovative technical support for the sustainable development of future marine communities.

[0022] The invention will now be further described with reference to the accompanying drawings.

[0023] As attached Figures 1 to 6 The image shows a periodic surge energy absorption system for a floating city at sea, such as... Figure 1 and 2 As shown, the project includes an artificial floating city floating on the sea surface. The floating city in this case is located in shallow sea. A surge energy absorption and utilization system 2 is set along the outline of the artificial floating city at a certain distance (2m). The surge energy absorption and utilization system 2 is composed of several wave energy absorption and power generation units 4 arranged in parallel at equal intervals. The wave energy absorption and power generation unit 4 includes a horizontal fixed support 3. The fixed support 3 is fixed to the artificial floating city or connected to it through a height-adjustable structure.

[0024] At any of the four wave-absorbing power generation units, the direction away from the artificial floating city is marked as the front, such as... Figure 5As shown, a power generation unit 35 is connected and installed at the lower front of the fixed bracket 3 via an inclined arm 7; the power generation unit 35 includes a power generation stator 17 and a power generation rotor 6. The axes of the power generation stator 17 and the power generation rotor 6 are horizontal and perpendicular to the front and rear directions. The cylindrical power generation rotor 6 rotates coaxially outside the power generation stator 17. An induction coil is provided on the power generation stator 17, and a permanent magnet is provided on the inner wall of the power generation rotor 6; the ends of the power generation stator 17 and the power generation rotor 6 are rotated and engaged by anti-corrosion sealed bearings; the lower end of the cylindrical power generation rotor (6) is level with the sea surface in a calm state. When the waves pass over the power generation rotor 6, their wave kinetic energy promotes the power generation rotor 6 to rotate counterclockwise first.

[0025] like Figure 5 As shown, the end of the inclined arm 7 is fixed to one end of the generator stator 17.

[0026] A layer of arc-shaped wound fabric tape 5b is attached to the outer wall of the cylindrical generator rotor 6. The clockwise end of the arc-shaped wound fabric tape 5b is fixedly connected to the outer wall of the generator rotor 6 via a connecting strip 13. The counterclockwise end of the arc-shaped wound fabric tape 5b is integrally connected tangentially to a rearwardly extending horizontally extending water-adhering fabric tape 5a. A structural strip 37 is fixedly connected to the rear end of the water-adhering fabric tape 5a along its contour. Two rearwardly parallel guide rods 10 are fixedly connected to both ends of the structural strip 37. The rear ends of the two guide rods 10 are vertically connected to a horizontal translation shaft 20. An upwardly extending upper wave-facing plate 8 and a downwardly extending lower wave-facing plate 9 are connected to the translation shaft 20. The upper wave-facing plate 8 and the lower wave-facing plate 9 form an angle α° between them. Figure 3 As shown, in the initial state, a°=140°, and the water-attached cloth strip 5a is at the same height as the sea surface in the calm state.

[0027] A pair of downward-extending guide seat brackets 11 are fixedly connected to the fixed bracket 3. Each guide seat bracket 11 has a guide seat 21 corresponding to the guide rod 10 fixedly connected to its lower end. The two guide rods 10 pass through the guide holes on the corresponding guide seats 21 along their length. The translation shaft 20 is initially attached to the rear side of the two pairs of guide seats 21. The other end of the generator stator 17 is fixedly connected to a fixed disk 14 through a fixed shaft 15. The fixed disk 14 is connected to the generator rotor 6 through a torsion spring 16a. The torsion spring 16a applies a clockwise elastic torque to the generator rotor 6, so that the water-adhesive cloth 5a is taut in the initial state. The length of the guide rod 10 is between 0.8m and 1.2m. The water-adhesive cloth 5a and the arc-shaped wound cloth 5b are nylon braided tapes with a fluororubber layer on the surface.

[0028] like Figure 5 and 6As shown, a pair of first bearing seats 25a are provided at the root of the lower wave-facing plate 9. The first bearing seats 25a are coaxially damped with the translation shaft 20 through a one-way damping bearing 23. The one-way damping bearing 23 causes damping during the downward swing of the lower wave-facing plate 9 around the translation shaft 20, and there is no damping during the upward swing of the lower wave-facing plate 9 around the translation shaft 20. A torsion spring 16b is coaxially installed at one end of the translation shaft 20. The torsion spring 16b applies a clockwise torque to the first bearing seats 25a, so that the lower wave-facing plate 9 always tends to swing downward under the action of torque. A lower limit seat 19 is integrally provided on the lower side of the middle part of the translation shaft 20. Under the action of the torsion spring 16b, the front side of the lower wave-facing plate 9 is limited to abut against the lower limit seat 19, so that the lower wave-facing plate 9 cannot swing downward further.

[0029] A pair of second bearing seats 25b are provided at the root of the upper wave-facing plate 8. The second bearing seats 25b are coaxially damped with the translation shaft 20 through a one-way damping bearing 23. The one-way damping bearing 23 causes damping during the upward swing of the upper wave-facing plate 8 around the translation shaft 20, and there is no damping during the downward swing of the upper wave-facing plate 8 around the translation shaft 20. A torsion spring 16c is coaxially installed at the other end of the translation shaft 20. The torsion spring 16c applies a counterclockwise torque to the second bearing seats 25b, so that the upper wave-facing plate 8 always tends to swing upward under the action of torque. An upper limit seat 18 is integrally provided on the upper side of the middle part of the translation shaft 20. Under the action of the torsion spring 16c, the front side of the upper wave-facing plate 8 is limited to abut against the upper limit seat 18, so that the upper wave-facing plate 8 cannot swing upward further.

[0030] Working principle:

[0031] In calm sea conditions, the water-absorbing fabric strip 5a is attached parallel to the calm sea surface. The waves exhibit periodic characteristics, and the wave absorption and energy conversion occur in the following stages:

[0032] Phase 1: As the crest of the first wave gradually propagates from the front to the edge of the artificial floating city 1, when the crest of the first wave passes the power generation rotor 6 and reaches the location of the water-adhering strip 5a, the originally horizontal water-adhering strip 5a bends and arches upward under the surging of the wave crest, thus lengthening the length of the water-adhering strip 5a under the surging of the wave crest. Since the total length of the arc-shaped winding strip 5b and the water-adhering strip 5a is constant, the lengthening of the water-adhering strip 5a will tangentially pull the power generation rotor 6 to overcome the torsion spring 16a and rotate counterclockwise. At the same time, the torsion spring 16a stores elastic potential energy, which in turn shortens the arc-shaped winding strip 5b. This process converts part of the kinetic energy of the first wave crest into the rotational mechanical energy of the power generation rotor 6 and generates electricity, while also achieving the initial effect of weakening the kinetic energy of the first wave.

[0033] Second stage: As the crest of the first wave continues to propagate backward, when the crest of the first wave leaves the water-adhering tape 5a and reaches the interval between the structural strip 37 and the translation axis 20, the power generation rotor 6 rotates clockwise to the initial position under the torque drive of the torsion spring 16a, so that both the arc-shaped winding tape 5b and the water-adhering tape 5a quickly return to their initial state, and the water-adhering tape 5a quickly straightens again. This process converts the elastic potential energy stored in the torsion spring 16a into the rotational mechanical energy of the power generation rotor 6 and generates electricity.

[0034] The third stage: As the crest of the first wave continues to propagate backward, it eventually impacts the upper wave-facing plate 8 and the lower wave-facing plate 9. During this process, the upper wave-facing plate 8 and the lower wave-facing plate 9 effectively absorb the lateral kinetic energy of the first wave crest. At the same time, the upper wave-facing plate 8 and the lower wave-facing plate 9 transmit the backward impact force of the first wave crest to the two guide rods 10 through the translation shaft 20. This causes the two guide rods 10 to pull the horizontal water-adhering cloth 5a backward, which in turn causes the water-adhering cloth 5a to pull the power generation rotor 6 counterclockwise against the torsion spring 16a. Meanwhile, the torsion spring 16a stores elastic potential energy, which in turn shortens the arc-shaped winding cloth 5b and lengthens the water-adhering cloth 5a. This process converts the lateral impact kinetic energy of the first wave crest into the rotational mechanical energy of the power generation rotor 6 and generates electricity, while further weakening the kinetic energy of the first wave.

[0035] Fourth stage: After the lateral impact of the first wave crest ends, the impact force disappears, and the power generation rotor 6 rotates clockwise to its initial position under the torque drive of torsion spring 16a. This causes the water-adhering cloth 5a to move forward through the two guide rods 10 to pull the translation shaft 20, causing the upper wave-facing plate 8 and the lower wave-facing plate 9 to move forward to their initial positions. This causes the arc-shaped winding cloth 5b and the water-adhering cloth 5a to gradually return to their initial state. At this point, one energy absorption and power generation cycle ends, and the system waits for the crest of the second wave.

[0036] In each of the above four stages, the generator rotor 6 will rotate once, and the induction coil on the generator stator 17 will generate four induced currents, thereby achieving the purpose of repeatedly absorbing and utilizing the kinetic energy of the wave crests.

[0037] During the aforementioned "third stage," if the impact force of the first wave is within the normal range, the impact force of the wave crest on the lower wave-facing plate 9 and the upper wave-facing plate 8 is insufficient to overcome the torsion springs 16b and 16c, thus the angle α° between the lower wave-facing plate 9 and the upper wave-facing plate 8 will not change. However, if the impact force of the first wave crest on the upper wave-facing plate 8 and the lower wave-facing plate 9 is too strong, the lower wave-facing plate 9 and the upper wave-facing plate 8 will respectively be affected by the excessive impact force. The torsion springs 16b and 16c overcome each other, swinging upwards and downwards by a certain angle respectively, thus reducing the angle α° between the lower wave-facing plate 9 and the upper wave-facing plate 8. This alleviates the excessive impact on the lower wave-facing plate 9 and the upper wave-facing plate 8, preventing the water-adhesive tape 5a from being damaged by excessive tension. Since ocean waves are periodic, if the impact force of the first wave crest is too strong, the impact force of the second wave crest is likely to be too strong as well. However, in this design, due to the unidirectional damping bearing... The presence of bearing 23 means that after the first wave crest impacts, the process of the lower wave-facing plate 9 and upper wave-facing plate 8, whose a° has decreased, regaining its size under the restoring force of torsion springs 16b and 16c, is inhibited by the one-way damping bearing 23. This slows down the process of the lower wave-facing plate 9 and upper wave-facing plate 8 regaining their size under the restoring force of torsion springs 16b and 16c, until the lower wave-facing plate 9 and upper wave-facing plate 8 are subjected to the second wave. When the wave crest impacts, the reduced a° does not fully recover to its initial state. This allows the lower wave-facing plate 9 and the upper wave-facing plate 8 to meet the impact of the second wave with a° slightly lower. This helps to prevent the water-adhering strip 5a from being subjected to excessive sudden tension under the action of the second, stronger wave. At the same time, the smaller a° reduces the water resistance encountered during the forward movement of the "fourth stage," allowing it to be completed more smoothly. If the impact force of the subsequent wave returns to normal, a° will automatically recover to its initial value.

[0038] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications 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.
