Description

Technical Field

[0001] The present invention relates to the technical field of utilization of marine renewable energy, and particularly to an anti-typhoon mooring system for a wave energy device. Background Art

[0002] Ocean wave energy is a renewable energy source, and wave energy devices can generate electrical energy using the energy of waves. However, the coastal environment in China is complex and harsh, typhoons occur frequently, and waves are easily affected by shallow water deformation and run-up, resulting in an increase in their movement amplitude. Therefore, wave energy devices need to have anti-typhoon functions.

[0003] Currently, when the anti-typhoon mooring system of a wave energy device resists wave loads in extreme sea conditions during typhoon weather, it increases its weight through a drainage function, causing the system to increase its draft depth, thereby reducing the waterplane near the water surface of the system, and further reducing wave loads and mooring tensions. However, due to the increase in the draft depth of the system, the overall weight of the system also increases, resulting in an increase in the inertia of the system, which will increase the mooring load and affect the stable operation of the system.

[0030] Compared with the prior art, the beneficial effect of the typhoon-resistant mooring system of the wave energy device according to the embodiment of the present invention lies in:

[0033] When encountering extreme sea conditions during typhoon weather, the driving fixing assembly instantaneously disengages from the ballast floating body, and the ballast floating body is not fixed. Since the density of the ballast floating body is greater than the density of seawater, the ballast floating body instantaneously sinks after leaving the opening, converting to the typhoon-resistant mode. There is a rope connected between the ballast floating body and the base floating body. As the ballast floating body located underwater descends, the total weight and buoyancy of the entire system remain unchanged, without increasing the inertia of the system. However, the vertical waterplane area of the base floating body decreases, reducing the heaving load and the vertical movement, thereby reducing the mooring load of the system, and the system can operate more stably.

[0045] As Figures 1-3 shown, a typhoon-resistant mooring system for a wave energy device according to an embodiment of the present invention includes: a base floating body 1, a wave absorption component 2, a ballast floating body 3, a fixing component 4, a rope 6, and a mooring component 5;

[0046] The base floating body 1 includes an upper floating body 11 and a lower floating body 12. The upper floating body 11 is connected to the top of the lower floating body 12, and the lower floating body 12 is provided with an opening 121;

[0047] The wave absorption component 2 is installed on the upper floating body 11;

[0048] The density of the ballast floating body 3 is greater than the density of seawater;

[0049] The fixing component 4 is installed on the base floating body 1, and the fixing component 4 is used to fix the ballast floating body 3 located in the opening 121;

[0050] The first end of the rope 6 is connected to the ballast floating body 3, and the second end of the rope 6 is connected to the lower floating body 12;

[0051] The mooring component 5 is connected to the lower floating body 12.

[0052] It should be noted that the base floating body 1 includes an upper floating body 11 and a lower floating body 12. The upper floating body 11 is connected to the top of the lower floating body 12. When the system is in use, the lower floating body 12 is located below the water surface, and the upper floating body 11 is located above the water surface.

[0053] The wave-absorbing component 2 is installed on the floating body 11 on the water surface and can capture wave energy. One end of the mooring component 5 is connected to the underwater floating body 12, and the other end of the mooring component 5 is connected to the seabed. The underwater floating body 12 is provided with an opening 121. In the initial state, the ballast floating body 3 is located within the opening 121, and the fixing component 4 fixes the ballast floating body 3 located within the opening 121, integrally fixing the ballast floating body 3 and the base floating body 1.

[0054] When encountering extreme sea conditions during typhoon weather, the driving fixing component 4 instantaneously disengages from the ballast floating body 3, and the ballast floating body 3 is no longer fixed. Since the density of the ballast floating body 3 is greater than that of seawater, the ballast floating body 3 instantaneously sinks out of the opening 121 and switches to the typhoon-resistant mode. A rope 6 is connected between the ballast floating body 3 and the base floating body 1. As the ballast floating body 3 located underwater descends, the total weight and buoyancy of the entire system remain unchanged, without increasing the inertia of the system. However, the vertical waterplane area of the base floating body 1 decreases, reducing the heaving load, and the vertical movement decreases, thereby reducing the mooring load of the system, enabling the system to operate more stably.

[0055] In addition, the ballast floating body 3 is connected to the base floating body 1 through the rope 6, which is equivalent to a tuned mass damper of the system under the action of waves, capable of reducing the movement of the base floating body 1, reducing the mooring load, improving the stability of the system, and at the same time preventing the loss of the ballast floating body 3.

[0056] The rope 6 is preferably a steel wire rope, which has high strength and light weight.

[0057] As Figure 1 shown, in this embodiment, further, there are two floating bodies 11 on the water surface. The two floating bodies 11 are respectively connected to both ends of the underwater floating body 12. There are two wave-absorbing components 2, and the two wave-absorbing components 2 are respectively installed on the two floating bodies 11 on the water surface.

[0058] It should be noted that the two floating bodies 11 on the water surface are respectively connected to both ends of the underwater floating body 12, and the two wave-absorbing components 2 are respectively installed on the two floating bodies 11 on the water surface. In addition to the symmetrical structure, which improves the stability of the system, the two wave-absorbing components 2 are arranged at both ends of the underwater floating body 12, capable of absorbing the wave energy on both sides of the system, broadening the wave-absorbing range.

[0059] As Figures 3-4 shown, in this embodiment, further, the floating body 11 on the water surface includes: two floating body seats 111. One end of each of the two floating body seats 111 is connected to the end of the underwater floating body 12, and the two floating body seats 111 are parallel to each other;

[0060] The wave-absorbing component 2 includes a wave-absorbing floating body 21 and a hinge shaft 22. Both ends of the hinge shaft 22 are respectively connected to the two floating body seats 111, and the wave-absorbing floating body 21 is rotatably connected to the hinge shaft 22.

[0061] It should be noted that the wave-absorbing floating body 21 and the water floating body 11 are connected by a hinge shaft 22, and relative movement can occur between the wave-absorbing floating body 21 and the water floating body 11, expanding the degrees of freedom of movement of the wave-absorbing floating body 21 and enabling it to more flexibly respond to wave impacts in different directions and frequencies.

[0062] As Figures 1-3 shown, in this embodiment, further, an accommodation cavity (not shown in the figure) is provided on one side of the opening 121 inside the base floating body 1, the fixing component 4 is arranged in the accommodation cavity, a communication hole (not shown in the figure) is provided on the side of the accommodation cavity close to the opening 121, and the communication hole penetrates through to the opening 121;

[0063] The fixing component 4 is arranged in the accommodation cavity. The fixing component 4 includes a telescopic member 41 and a control component 42. The telescopic end of the telescopic member 41 passes through the communication hole, and the telescopic end of the telescopic member 41 is used to abut against the ballast floating body 3 located in the opening 121 when it extends, and the control component 42 is connected to the telescopic member 41 to control the telescopic movement of the telescopic end.

[0064] It should be noted that the fixing component 4 is arranged in the accommodation cavity to avoid being damaged by seawater. A communication hole is provided on the side of the accommodation cavity close to the opening 121, and the communication hole penetrates through to the opening 121. The telescopic end of the telescopic member 41 passes through the communication hole. When the telescopic end extends, the telescopic end can penetrate into the opening 121 to abut against the ballast floating body 3, and the ballast floating body 3 is squeezed between the telescopic end and the wall surface of the base floating body 1, thereby fixing the position of the ballast floating body 3;

[0065] When the telescopic end contracts, the telescopic end retracts into the communication hole, and the ballast floating body 3 located in the opening 121 is not limited by the telescopic end, and the ballast floating body 3 sinks with one key.

[0066] As Figures 1-3 shown, in this embodiment, further, there are two fixing components 4, and accommodation cavities (not shown in the figure) are provided on both sides of the opening 121 inside the base floating body 1, and the two fixing components 4 are respectively arranged in the two accommodation cavities.

[0067] It should be noted that the two fixing components 4 are respectively arranged in the two accommodation cavities, and the two accommodation cavities are respectively located on both sides of the opening 121. Therefore, the telescopic ends of the two telescopic members 41 can abut against the ballast floating body 3 from opposite directions for limiting, and the ballast floating body 3 can be fixed more stably.

[0068] As Figure 1 、 6 -7 shown, in this embodiment, further, a pin hole 31 is provided on the side of the ballast floating body 3 close to the telescopic member 41, and the telescopic end of the telescopic member 41 is used to insert into the pin hole 31 when it extends.

[0069] It should be noted that a pin hole 31 is provided on one side of the ballast floating body 3 close to the telescopic member 41. When the telescopic end of the telescopic member 41 extends, it is inserted into the pin hole 31. Compared with abutting against the surface of the ballast floating body 3, the fixation of the ballast floating body 3 is more stable.

[0070] As Figure 5 shown, in this embodiment, further, the telescopic member 41 includes:

[0071] a hydraulic cylinder 411, with a first oil port 4111 and a second oil port 4112 respectively arranged at both ends of the hydraulic cylinder 411;

[0072] a hydraulic rod 412, which telescopically slides within the hydraulic cylinder 411, and the hydraulic rod 412 is used to abut against the ballast floating body 3 located within the opening 121 when it extends;

[0073] The control assembly 42 includes:

[0074] a first oil cylinder 421;

[0075] a second oil cylinder 422;

[0076] a two-position four-way solenoid valve 423, the two-position four-way solenoid valve 423 includes four solenoid valve ports 4231, and the four solenoid valve ports 4231 are respectively connected to the first oil cylinder 421, the second oil cylinder 422, the first oil port 4111 and the second oil port 4112.

[0077] It should be noted that a first oil port 4111 and a second oil port 4112 are respectively arranged at both ends of the hydraulic cylinder 411. The first oil port 4111 communicates with the rodless cavity within the hydraulic cylinder 411, and the second oil port 4112 communicates with the rod cavity within the hydraulic cylinder 411.

[0078] In the initial state, the first oil port 4111 is at high oil pressure and the second oil port 4112 is at low oil pressure. At this time, the hydraulic cylinder 411 drives the hydraulic rod 412 to extend outwards, and the hydraulic rod 412 abuts against the ballast floating body 3 located within the opening 121. Specifically, the hydraulic rod 412 is inserted into the pin hole 31.

[0079] When encountering extreme sea conditions during typhoon weather, drive the two-position four-way solenoid valve 423 to change its direction. The first oil port 4111 is at low oil pressure and the second oil port 4112 is at high oil pressure. At this time, the hydraulic cylinder 411 drives the hydraulic rod 412 to contract inwards, and the hydraulic rod 412 disengages from the ballast floating body 3. Specifically, the hydraulic rod 412 disengages from the pin hole 31.

[0080] The telescopic end of the telescopic member 41 is the hydraulic rod 412.

[0081] Furthermore, the fixing component 4 includes a plurality of telescopic members 41 and a plurality of control components 42, which are in one-to-one correspondence. On one side of the ballast float 3 close to the telescopic member 41, there are a plurality of pin holes 31, which are in one-to-one correspondence with the plurality of telescopic members 41. Thus, the telescopic ends of the plurality of telescopic members 41 can be inserted into the pin holes 31 to improve the fixing effect on the ballast float 3.

[0082] As Figure 7 shown, in this embodiment, further, it further includes:

[0083] A load sensor 7, which is installed on the mooring component 5 and is connected to the control component 42.

[0084] It should be noted that the load sensor 7 is installed on the mooring component 5 to detect the mooring load. When the detected mooring load exceeds the preset value, the load sensor 7 sends a corresponding signal to the control component 42, and the control component 42 controls the telescopic end of the telescopic member 41 to contract.

[0085] Specifically, the load sensor 7 is connected to a two-position four-way solenoid valve 423. When the detected mooring load exceeds the preset value, the load sensor 7 sends a corresponding signal to the two-position four-way solenoid valve 423, and the two-position four-way solenoid valve 423 changes its direction.

[0086] As Figures 1-2 shown, in this embodiment, further, the mooring component 5 includes two mooring members 51, and the two mooring members 51 are respectively connected to both ends of the underwater float 12.

[0087] It should be noted that the two mooring members 51 are respectively connected to both ends of the underwater float 12, and the two ends of the underwater float 12 are symmetrically stressed, so as to evenly disperse external forces such as waves and water currents to the two mooring members 51, significantly reducing the load peak value of a single mooring member 51 and improving the stability of the overall system.

[0088] As Figure 2 shown, in this embodiment, further, the mooring member 51 includes an anchor 511 and a mooring cable 512. The first end of the mooring cable 512 is connected to the underwater float 12, and the second end of the mooring cable 512 is connected to the anchor 511.

[0089] It should be noted that the anchor 511 transmits the grasping force to the underwater float 12 through the mooring cable 512 to avoid local stress concentration. Optimization of the pre-tension and opening angle of the mooring cable 512 can improve the response ability of the system.

[0090] The working process of the present invention is as follows: The base float 1 includes a water surface float 11 and an underwater float 12. The water surface float 11 is connected to the top of the underwater float 12. When the system is in use, the underwater float 12 is located below the water surface, and the water surface float 11 is located above the water surface.

[0091] The wave-absorbing component 2 is installed on the floating body 11 on the water surface and can capture wave energy. One end of the mooring component 5 is connected to the underwater floating body 12, and the other end of the mooring component 5 is connected to the seabed. The underwater floating body 12 is provided with an opening 121. In the initial state, the ballast floating body 3 is located within the opening 121, and the fixing component 4 fixes the ballast floating body 3 located within the opening 121, integrating the ballast floating body 3 and the base floating body 1 into one entity.

[0092] When encountering extreme sea conditions during typhoon weather, the driving fixing component 4 instantaneously detaches from the ballast floating body 3, and the ballast floating body 3 is no longer fixed. Since the density of the ballast floating body 3 is greater than that of seawater, the ballast floating body 3 instantaneously sinks out of the opening 121 and switches to the typhoon-resistant mode. A rope 6 is connected between the ballast floating body 3 and the base floating body 1. As the ballast floating body 3 located underwater descends, the total weight and buoyancy of the entire system remain unchanged, and the inertia of the system will not increase. However, at this time, the base floating body 1 is in a hollow state, and the vertical and horizontal environmental loads received are significantly reduced. The reduction of the vertical environmental load can reduce the vertical motion amplitude, and the reduction of the horizontal environmental load can reduce the horizontal motion amplitude. At the same time, due to the large mass of the ballast floating body 3 and its vertical suspension, a tuned mass damper is formed, which can further reduce the horizontal motion of the wave energy device. The reduction of the vertical and horizontal motions can reduce the tension of the mooring cable 512 and lower the mooring load, ensuring that the system can operate more stably and safely.

[0093] In summary, the embodiment of the present invention provides a typhoon-resistant mooring system for a wave energy device, which can reduce the mooring load and ensure that the system can operate more stably and safely.

[0094] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
