Description

Technical Field

[0001] The present invention belongs to the field of wave energy dissipation and absorption for floating cities. Background Art

[0002] The wave dissipation and protection system arranged around the floating city in the ocean can significantly reduce the impact intensity of sea waves, thereby enhancing the durability and safety of the edge structure of the floating platform. By absorbing and dispersing the kinetic energy of water flow, this device can not only inhibit the displacement tendency of the floating island body caused by sea waves, but also reduce the noise level, significantly improving the living comfort. It is worth noting that if the remaining kinetic energy that has not been absorbed is converted into electrical energy, it can not only extend the service life of the infrastructure of the floating city in the ocean, but also enhance the ecological benefits through green energy conversion technology, providing innovative technical support for the sustainable development of future offshore communities. Summary of the Invention

[0003] Object of the Invention: In order to overcome the deficiencies in the prior art, the present invention provides a periodic surge energy absorption and utilization system for a floating city at sea, aiming to repeatedly absorb and utilize the kinetic energy of the wave crests.

[0004] Technical Solution: To achieve the above object, a periodic surge energy absorption and utilization system for a floating city at sea according to the present invention is composed of a number of wave energy absorption and power generation units arranged side by side at equal intervals;

[0005] At any wave energy absorption and power generation unit, the direction away from the artificial floating city is denoted as the front. The wave energy absorption and power generation unit includes a horizontal fixed bracket, and a power generation unit is installed at the front lower part of the fixed bracket through an inclined 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-rear direction. The cylindrical power generation rotor rotates coaxially outside the power generation stator. An induction coil is provided on the power generation stator, and permanent magnets are provided 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 flush with the sea surface in the calm state.

[0007] Further, an arc-shaped winding belt is attached to the outer wall surface of the cylindrical power generation rotor. The clockwise end of the arc-shaped winding belt is fixedly connected to the outer wall surface of the power generation rotor through a connecting strip;

[0008] The counterclockwise end of the arc-shaped winding belt is integrally connected with a water-attached belt extending horizontally backward in the tangential direction. The rear end of the water-attached belt is fixedly connected with a structural strip along the contour. Both ends of the structural strip are fixedly connected with two guiding pull rods extending backward in parallel. The rear ends of the two guiding pull rods are commonly and perpendicularly connected to a horizontal translation shaft. An upward wave-facing plate extending obliquely upward and a downward wave-facing plate extending obliquely downward are connected to the translation shaft.

[0009] Furthermore, a pair of guide seat brackets extending downward are fixedly connected to the fixed bracket. At the lower end of each guide seat bracket, a guide seat corresponding to the guide pull rod is fixedly connected. The two guide pull rods pass through the guide holes on the corresponding guide seats along the length direction; the translation shaft abuts against the rear sides of the two pairs of guide seats in the initial state.

[0010] Furthermore, at the other end of the power generation stator, a fixed disk is fixedly connected through a fixed shaft. The fixed disk and the power generation rotor are connected by a torsion spring a; the torsion spring a applies an elastic torsion force in the clockwise direction to the power generation rotor, so that the water-attached cloth belt is in a straightened state 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 in one-way damping cooperation with the translation shaft coaxially through one-way damping bearings. The one-way damping bearings generate damping during the process of the lower wave-facing plate swinging downward around the translation shaft, and there is no damping during the process of the lower wave-facing plate swinging upward around the translation shaft; at one end of the translation shaft, a torsion spring b is coaxially installed. The torsion spring b applies a clockwise torque to the first bearing seat, so that the lower wave-facing plate always has a downward swing trend under the action of the torsion force; a lower limit seat is integrally provided on the lower side of the middle part 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 in one-way damping cooperation with the translation shaft coaxially through one-way damping bearings. The one-way damping bearings generate damping during the process of the upper wave-facing plate swinging upward around the translation shaft, and there is no damping during the process of the upper wave-facing plate swinging downward around the translation shaft; at the other end of the translation shaft, a torsion spring c is coaxially installed. The torsion spring c applies a counterclockwise torque to the second bearing seat, so that the upper wave-facing plate always has an upward swing trend under the action of the torsion force; an upper limit seat is integrally provided on the upper side of the middle part of the translation shaft. Under the action of the torsion spring c, 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-attached cloth belt is at the same height as the sea surface in the calm state;

[0014] Furthermore, it further includes an artificial floating city floating on the sea surface. The wave energy absorption power generation system is at a certain distance outside the edge contour of the artificial floating city. The fixed bracket is fixedly connected to the artificial floating city or connected through a height-adjustable structure.

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

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

[0023] As shown in the attached Figures 1 to 6 A periodic surge energy absorption and utilization system for an offshore floating city as shown, such as Figure 1 and 2 shown, includes an artificial floating city floating on the sea surface. The offshore floating city in this case is located in shallow water. At a certain distance (2m) outside the outer contour 1 of the artificial floating city, a wave energy absorption power generation system 2 is arranged along the contour. The wave energy absorption power generation system 2 is composed of a number of wave energy absorption power generation units 4 arranged side by side at equal intervals; the wave energy absorption power generation unit 4 includes a horizontal fixed bracket 3, and the fixed bracket 3 is fixed to the artificial floating city or connected through a height-adjustable structure.

[0024] At any wave energy absorption power generation unit 4, the direction away from the artificial floating city is recorded as the front, as Figure 5As shown in the figure, a power generation unit 35 is installed at the front lower part of the fixed bracket 3 through 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-rear direction. 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 permanent magnets are 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 rotationally matched through anti-corrosion sealed bearings; the lower end of the cylindrical power generation rotor (6) is flush with the sea surface in a calm state. When the sea wave passes through the power generation rotor 6, the wave kinetic energy promotes the power generation rotor 6 to rotate counterclockwise first.

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

[0026] A layer of arc-shaped winding belt 5b is attached to the outer wall surface of the cylindrical power generation rotor 6. The clockwise end of the arc-shaped winding belt 5b is fixedly connected to the outer wall surface of the power generation rotor 6 through a connecting strip 13; the counterclockwise end of the arc-shaped winding belt 5b is integrally connected with a water-attached belt 5a extending horizontally backward along the tangent direction. The rear end of the water-attached belt 5a is fixedly connected with a structural strip 37 along the contour. Both ends of the structural strip 37 are fixedly connected with two guiding pull rods 10 extending backward in parallel. The rear ends of the two guiding pull rods 10 are commonly vertically connected with a horizontal translation shaft 20; An upward wave-facing plate 8 extending obliquely upward and a downward wave-facing plate 9 extending obliquely downward are connected to the translation shaft 20. An angle of a° is formed between the upward wave-facing plate 8 and the downward wave-facing plate 9. As Figure 3 shown, in the initial state, a° = 140°, and at the same time, the water-attached belt 5a is flush with the sea surface in a calm state.

[0027] A pair of guiding seat brackets 11 extending downward are fixedly connected to the fixed bracket 3. The lower ends of the guiding seat brackets 11 are fixedly connected with guiding seats 21 corresponding to the guiding pull rods 10. The two guiding pull rods 10 pass through the guide holes on the corresponding guiding seats 21 along the length direction; the translation shaft 20 abuts against the rear sides of the two pairs of guiding seats 21 in the initial state; the other end of the power generation stator 17 is fixedly connected with a fixed disk 14 through a fixed shaft 15. The fixed disk 14 and the power generation rotor 6 are connected by a torsion spring 16a; the torsion spring 16a applies an elastic torsion force in the clockwise direction to the power generation rotor 6, so that the water-attached belt 5a is in a taut state in the initial state. The length of the guiding pull rod 10 is between 0.8 m and 1.2 m. The water-attached belt 5a and the arc-shaped winding belt 5b are nylon braided belt bodies with a fluororubber layer on the surface.

[0028] As Figure 5 and 6As shown in the figure, 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 and unidirectionally damped with the translation shaft 20 through a one-way damping bearing 23. The one-way damping bearing 23 generates damping during the process of the lower wave-facing plate 9 swinging downward around the translation shaft 20, and there is no damping during the process of the lower wave-facing plate 9 swinging upward around the translation shaft 20; one end of the translation shaft 20 is coaxially installed with a b torsion spring 16b, and the b torsion spring 16b applies a clockwise torque to the first bearing seat 25a, so that the lower wave-facing plate 9 always has a downward swing trend under the action of the torsion force; 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 b torsion spring 16b, the front side of the lower wave-facing plate 9 is limited and abuts 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 and unidirectionally damped with the translation shaft 20 through a one-way damping bearing 23. The one-way damping bearing 23 generates damping during the process of the upper wave-facing plate 8 swinging upward around the translation shaft 20, and there is no damping during the process of the upper wave-facing plate 8 swinging downward around the translation shaft 20; the other end of the translation shaft 20 is coaxially installed with a c torsion spring 16c, and the c torsion spring 16c applies a counterclockwise torque to the second bearing seat 25a, so that the upper wave-facing plate 8 always has an upward swing trend under the action of the torsion force; 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 c torsion spring 16c, the front side of the upper wave-facing plate 8 is limited and abuts against the upper limit seat 18, so that the upper wave-facing plate 8 cannot swing upward further.

[0030] Working principle:

[0031] In the calm state, the water-attached belt 5a is parallel to the calm sea surface. The sea waves are periodic, and the wave absorption and energy conversion are divided into the following stages:

[0032] The first stage: During the process of the wave crest of the first wave of sea waves gradually propagating backward from the front to the edge contour 1 of the artificial floating city, when the wave crest of the first wave of sea waves passes through the power generation rotor 6 and just reaches the position where the water-attached belt 5a is located, the originally horizontal water-attached belt 5a bends upward following the surge of the wave crest of the sea waves, so that the length of the water-attached belt 5a becomes longer under the surge of the wave crest of the sea waves. Since the total length of the arc-shaped wound belt 5b and the water-attached belt 5a is constant, the elongation of the water-attached belt 5a will tangentially pull the power generation rotor 6 to rotate counterclockwise against the a torsion spring 16a. At the same time, the a torsion spring 16a stores elastic potential energy, and then the arc-shaped wound belt 5b becomes shorter. This process converts a part of the kinetic energy of the wave crest of the first wave of sea waves into the rotational mechanical energy of the power generation rotor 6 and generates electricity, and at the same time realizes the function of initially weakening the kinetic energy of the first wave of sea waves;

[0033] Second stage: As the crest of the first wave continues to propagate backward, when the crest of the first wave leaves the water-attached tape 5a and reaches the interval between the structural bar 37 and the translation axis 20, the power generation rotor 6 rotates clockwise to the initial position under the torsional drive of the a torsion spring 16a. As a result, both the arc-shaped winding tape 5b and the water-attached tape 5a quickly return to the initial state, and the water-attached tape 5a quickly becomes straight again. In this process, the elastic potential energy stored and released by the a torsion spring 16a is converted into the rotational mechanical energy of the power generation rotor 6 to generate electricity;

[0034] Third stage: As the crest of the first wave continues to propagate backward, finally, the crest of the first wave hits the upper wave-facing plate 8 and the lower wave-facing plate 9 backward. In this process, the upper wave-facing plate 8 and the lower wave-facing plate 9 effectively absorb the lateral kinetic energy of the crest of the first wave. At the same time, the upper wave-facing plate 8 and the lower wave-facing plate 9 transfer the backward impact force received from the crest of the first wave to the two guiding tie rods 10 through the translation axis 20. As a result, the two guiding tie rods 10 pull the horizontal water-attached tape 5a backward, causing the water-attached tape 5a to tangentially pull the power generation rotor 6 to rotate counterclockwise against the a torsion spring 16a. At the same time, the a torsion spring 16a stores elastic potential energy, and then the arc-shaped winding tape 5b becomes shorter and the water-attached tape 5a becomes longer. In this process, the lateral impact kinetic energy of the crest of the first wave is converted into the rotational mechanical energy of the power generation rotor 6 to generate electricity, and at the same time, the kinetic energy of the first wave is further weakened;

[0035] Fourth stage: After the lateral impact of the crest of the first wave ends and the impact force disappears, the power generation rotor 6 rotates clockwise to the initial position under the torsional drive of the a torsion spring 16a. As a result, the water-attached tape 5a pulls the translation axis 20 forward through the two guiding tie rods 10, causing the upper wave-facing plate 8 and the lower wave-facing plate 9 to move forward to the initial position. As a result, both the arc-shaped winding tape 5b and the water-attached tape 5a gradually return to the initial state. Thus, an energy absorption and power generation cycle ends and waits for the crest of the second wave;

[0036] In each of the above four stages, the power generation rotor 6 rotates once, and four induced currents are generated in the induction coil on the power generation stator 17, so as to achieve the purpose of repeatedly absorbing and utilizing the kinetic energy of the wave crest;

[0037] In the above-mentioned "third stage", the impact force of the first wave is within the normal range, and the impact force of the wave crest of normal impact strength on the lower wave board 9 and the upper wave board 8 cannot overcome the torsion spring b 16b and the torsion spring c 16c, so that the angle a° between the lower wave board 9 and the upper wave board 8 will not change; however, if the intensity of the crest of the first wave hitting the upper wave board 8 and the lower wave board 9 backwards is too strong, the lower wave board 9 and the upper wave board 8 will be respectively Overcoming the torsion spring b 16b and the torsion spring c 16c and swinging upward and downward by a certain angle respectively, the angle a° between the lower wave-facing plate 9 and the upper wave-facing plate 8 becomes smaller, thereby alleviating the excessive impact strength of the lower wave-facing plate 9 and the upper wave-facing plate 8, and preventing the water-adhering cloth belt 5a from being damaged by excessive tension; because the waves are periodic, if the impact force of the crest of the first wave is too strong, the impact force of the crest of the second wave is also likely to be too strong, and in this solution, due to the one-way damping bearing Due to the existence of 23, after the crest impact of the first wave ends, the lower wave board 9 and the upper wave board 8 whose a° has been reduced are inhibited by the one-way damping bearing 23 in the process of increasing a° again under the action of the restoring force of the b torsion spring 16b and the c torsion spring 16c, so that the process of increasing a° again under the action of the restoring force of the b torsion spring 16b and the c torsion spring 16c becomes slow, until the lower wave board 9 and the upper wave board 8 are impacted by the second wave. When the wave crest hits, the reduced a° still does not fully recover to the initial state, so that the lower wave board 9 and the upper wave board 8 meet the impact of the second wave of waves with a smaller a°, thereby preventing the water-adhering fabric 5a from being subjected to excessive sudden pull under the action of the second wave of strong waves. At the same time, the smaller a° makes the forward movement process of the "fourth stage" less subject to water resistance and is completed more smoothly; if the impact force of subsequent waves returns to normal, a° automatically recovers to the initial state.

[0038] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
