Description

Technical Field

[0001] The invention belongs to the technical field of mooring systems, and in particular relates to a novel heavy block pulley energy storage mooring system and an ocean floating platform. Background Art

[0002] As the carrier of offshore structures, the design of fixed mooring systems for offshore floating platform structures is particularly critical. Mooring systems are systems used to fix ships, floating platforms or other offshore structures in water bodies. They are usually composed of anchors, mooring cables, connectors, anchor chains and floating platform structures to prevent offshore structures from drifting due to tides, wind, waves or ocean currents. Mooring systems ensure the stability and position control of these structures in the water through anchoring, cables or chains. Mooring systems play a vital role in scenarios such as ship mooring, offshore platform operations, and floating facility maintenance.

[0003] The traditional mooring system design varies according to the platform carrier, including catenary mooring system, tension mooring system, single-point mooring system and multi-point mooring system. However, due to various objective factors such as the large size and heavy weight of the design platform, the existing mooring system has a large number of designed mooring chains, and the bearing capacity of a single mooring chain is too large, resulting in stringent material selection requirements, which in turn leads to expensive mooring system design costs. In addition, the existing mooring system usually only considers how to stabilize and constrain the overall structure of the floating platform in design, without considering the energy-saving effect at the same time, resulting in low effective energy utilization. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a novel heavy block pulley energy storage mooring system and an ocean floating platform, aiming to solve the problems of how to reduce the manufacturing cost of the ocean floating platform and how to improve the safety, energy utilization and environmental benefits of the ocean floating platform.

[0005] To achieve the above purpose, the technical solution adopted in this application is:

[0006] In the first aspect, a novel weight pulley energy storage mooring system is provided, comprising a floating body, an energy conversion assembly arranged on the floating body, a counterweight assembly located below the floating body, and a mooring chain connected to the counterweight assembly, wherein one end of the mooring chain is anchored at the bottom of the water, and the other end of the mooring chain is connected to the counterweight assembly, the energy conversion assembly comprises a rotatable rotating shaft, a traction rope wound around the rotating shaft, and a generator transmission-connected to the rotating shaft, one end of the traction rope is connected to the counterweight assembly, the rotating shaft has a first state of remaining stationary and a second state of being rotatable, when the rotating shaft is in the first state, the rotating shaft fixes the traction rope, when the rotating shaft is in the second state, the counterweight assembly falls under the action of gravity so that the traction rope drives the rotating shaft to rotate, and the generator is used to convert the rotational kinetic energy of the rotating shaft into electrical energy.

[0007] In some embodiments, the counterweight assembly includes a pulley and a weight block, the pulley is connected to the traction rope, the mooring chain is wound around the pulley, one end of the mooring chain is anchored to the bottom of the water, and the other end of the mooring chain is connected to the weight block.

[0008] In some embodiments, the energy conversion assembly further includes a bracket and a transmission member, the rotating shaft is rotatably connected to the bracket, and the transmission member connects the rotating shaft and the rotor of the generator so that the rotating shaft and the rotor of the generator rotate synchronously.

[0009] In some embodiments, the novel weight pulley energy storage mooring system further includes an energy storage device disposed on the floating body, and the energy storage device is used to store the electrical energy generated by the generator.

[0010] In some embodiments, the energy conversion component is disposed on a surface of the floating body facing away from the counterweight component, the floating body is provided with a through hole for the traction rope to pass through, and the traction rope is connected to the counterweight component via the through hole.

[0011] In some embodiments, a buffer structure is disposed on the bottom surface of the floating body. The buffer structure is disposed on the moving path of the counterweight assembly. The buffer structure can be elastically deformed under pressure to buffer the impact of the counterweight assembly.

[0012] In some embodiments, the buffer structure is a spring, the spring is sleeved on the traction rope, and one end of the spring facing away from the counterweight assembly is connected to the bottom surface of the floating body.

[0013] In some embodiments, a plurality of pulleys are arranged at intervals, a plurality of energy conversion assemblies are arranged at intervals, each pulley corresponds to each energy conversion assembly one by one, a plurality of mooring chains are arranged, each mooring chain is respectively wound around each pulley, and each mooring chain is connected to the same weight block.

Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0028] See also Figures 1 to 4 The embodiment of the present application provides a novel weight block pulley energy storage mooring system, comprising a floating body 10, an energy conversion assembly 20 arranged on the floating body 10, a counterweight assembly 30 located below the floating body 10, and a mooring chain 40 connected to the counterweight assembly 30, one end of the mooring chain 40 is anchored at the bottom of the water, and the other end of the mooring chain 40 is connected to the counterweight assembly 30. The energy conversion assembly 20 comprises a rotating shaft 21 arranged to rotate, a traction rope 22 wound around the rotating shaft 21, and a generator 23 connected to the rotating shaft 21 in a transmission manner. One end of the traction rope 22 is connected to the counterweight assembly 30, and the counterweight assembly 30 keeps the traction rope 22 taut by its own gravity. The rotating shaft 21 has a first state of being stationary and a second state of being rotatable. When the rotating shaft 21 is in the first state, the rotating shaft 21 fixes the traction rope 22. When the rotating shaft 21 is in the second state, the counterweight assembly 30 falls under the action of gravity, so that the traction rope 22 drives the rotating shaft 21 to rotate, and the generator 23 converts the rotational kinetic energy of the rotating shaft 21 into electrical energy.

[0029] It can be understood that the floating body 10 floats on the water surface due to the buoyancy, and the counterweight assembly 30 has a certain weight, so the counterweight assembly 30 sinks into the water due to its own gravity, and the position of the counterweight assembly 30 in the water can rise and fall. One end of the mooring chain 40 is anchored to the bottom of the water. Specifically, one end of the mooring chain 40 can be connected to the anchor structure 60, and the anchor structure 60 enables one end of the mooring chain 40 to be anchored to the bottom of the water.

[0030] It should be noted that in the initial state when no power generation is performed, the rotating shaft 21 is in the first state, in which the rotating shaft 21 is locked and cannot rotate, the traction rope 22 is wound and fixed on the rotating shaft 21, and the height of the counterweight assembly 30 does not change. At this time, the counterweight assembly 30 is at a preset height relative to the bottom of the water. When power generation starts, the rotating shaft 21 is switched from the first state to the second state, the locked state of the rotating shaft 21 is released so that it can rotate. At this time, the counterweight assembly 30 falls under the action of gravity, the traction rope 22 is released, and the friction between the traction rope 22 and the rotating shaft 21 drives the rotating shaft 21 to rotate. The generator 23 converts the rotational kinetic energy of the rotating shaft 21 into electrical energy, thereby realizing the conversion of the gravitational potential energy of the counterweight assembly 30 into electrical energy.

[0031] The novel weight block pulley energy storage mooring system provided in the present application can use the weight of the counterweight assembly 30 itself to offset the buoyancy of the ocean floating platform in the ocean, effectively reduce the constraint load of the ocean floating platform design, and further reasonably reduce the number of mooring chains 40 in the mooring system and the design load size of each mooring chain 40. Since the design number and design strength of the mooring chains 40 are reduced, the design cost is significantly reduced, which greatly reduces the overall cost of the entire ocean floating platform and effectively reduces the cost. In addition, the counterweight assembly 30 also has the function of acting as a damper. When the ocean floating platform as a whole is affected by extreme wind, wave and current loads, the counterweight assembly 30 can consume the force exerted on the ocean floating platform to ensure the safety and stability of the structure above the sea level. Moreover, by setting up the energy conversion component 20, when the counterweight component 30 falls due to gravity, the traction rope 22 will drive the rotating shaft 21 to rotate, and the generator 23 will convert the rotational kinetic energy of the rotating shaft 21 into electrical energy, thereby realizing the conversion of the gravitational potential energy of the counterweight component 30 into electrical energy, providing additional energy for the overall stability of the mooring system, and the energy conversion efficiency is high and pollution-free, which is conducive to improving energy utilization and environmental benefits.

[0032] In some embodiments, Figure 1 As shown, the counterweight assembly 30 includes a pulley 31 and a weight 32. The pulley 31 is connected to the traction rope 22. The mooring chain 40 is wound around the pulley 31. One end of the mooring chain 40 is anchored to the bottom of the water, and the other end of the mooring chain 40 is connected to the weight 32. By setting the pulley 31, when the floating body 10 is displaced by an external force, the mooring chain 40 is pulled under the gravity of the weight 32, and the pulled mooring chain 40 can change the force direction through the pulley 31. Through the pulley 31, the tension on the mooring chain 40 is kept stable, avoiding the mooring chain 40 from suddenly changing too much when the mooring system is subjected to extreme wind and waves.

[0033] In some embodiments, Figure 3As shown, the energy conversion assembly 20 also includes a bracket 24 and a transmission member 25. The bracket 24 is connected to the floating body 10, the rotating shaft 21 is rotatably connected to the bracket 24, and the transmission member 25 connects the rotating shaft 21 and the rotor of the generator 23, so that the rotating shaft 21 and the rotor of the generator 23 rotate synchronously, thereby realizing power generation. It should be noted that the rotor of the generator 23 is usually a rotating magnet or a current-carrying conductor, which together with the stator (fixed part) constitutes the basic structure of the generator 23. When the rotor rotates in the stator, the magnetic field generated by the rotor also rotates together, causing the magnetic flux in the stator winding to change. According to the law of electromagnetic induction, when the magnetic flux in a closed circuit changes, an induced electromotive force will be generated in the circuit. If the stator winding is a closed loop, then under the action of the induced electromotive force, an induced current will be generated, thereby realizing the generation of electric energy. The rotating shaft 21 and the rotor of the generator 23 are connected by the transmission member 25, so that the rotating shaft 21 and the rotor of the generator 23 rotate synchronously, the structure is simple and the transmission efficiency is high, which is conducive to improving the power generation efficiency.

[0034] In a specific embodiment, the rotating shaft 21 and the bracket 24 can constitute a winch, which has a compact structure, small size, light weight, is easy to move and install between different locations, and is simple to operate and intuitive to use. The winch also has a high load-bearing capacity, can lift or pull heavier objects, and can achieve precise operation and control through an intelligent control system. Of course, in other possible implementations, the rotating shaft 21 and the bracket 24 can constitute an electric winch, etc., and the embodiment of the application does not make the sole limitation on this.

[0035] It can be understood that in order to prepare for the next power generation, the traction rope 22 can be tightened by rotating the rotating shaft 21, thereby lifting the pulley 31 and the weight 32, so that the pulley 31 and the weight 32 are lifted to a sufficiently high height so that the pulley 31 and the weight 32 have greater gravitational potential energy, so that the generator 23 can finally convert more electrical energy.

[0036] In some embodiments, the energy conversion component 20 also includes an energy storage device, which is used to store the electric energy generated by the generator 23. By setting up an energy storage device to store electric energy, the energy storage device can flexibly allocate electric energy according to the power generation and power demand of the generator 23 to achieve optimal configuration of energy. Since the power generation power of the generator 23 may not fully match the actual load demand, when the load is low, if the generator 23 continues to generate electricity at a higher power, it will cause energy waste. The energy storage device can store excess electric energy when the load is low and release electric energy when the load is peak, so that the generator 23 can operate more stably in the high-efficiency power generation range, thereby improving the energy utilization efficiency of the entire power generation system.

[0037] Optionally, the energy storage device can be an electrochemical capacitor, which refers to a new type of energy storage element based on electrode materials such as high specific surface area carbon materials, metal oxides and conductive polymers. When the counterweight assembly 30 just begins to descend, its descent speed is low, so the power is low. At this time, the electricity stored in the electrochemical capacitor can be released to meet the power generation demand. Compared with traditional capacitors, electrochemical capacitors have larger capacity, higher energy, wider operating temperature range and extremely long service life. Of course, in other possible implementations, the energy storage device can also be a battery. The battery has stable performance and high reliability. It can operate stably for a long time under various environmental conditions, providing reliable protection for the energy storage device, and the battery can be reused many times, reducing the impact of discarded batteries on the environment. It can also output electrical energy smoothly and avoid damage to equipment caused by power fluctuations.

[0038] In some embodiments, the energy conversion assembly 20 is disposed on the surface of the floating body 10 away from the counterweight assembly 30, and the floating body 10 is provided with a through hole for the traction rope 22 to pass through, and the traction rope 22 is connected to the counterweight assembly 30 through the through hole. By arranging the energy conversion assembly 20 on the surface of the floating body 10 away from the counterweight assembly 30, that is, arranging it on the top surface of the floating body 10, the influence of waves on the energy conversion assembly 20 can be reduced, thereby increasing the service life of the energy conversion assembly 20.

[0039] In some embodiments, Figure 1 As shown, a buffer structure 50 is provided on the bottom surface of the floating body 10. The buffer structure 50 is arranged on the moving path of the counterweight assembly 30. The buffer structure 50 can be elastically deformed under pressure to buffer the impact of the counterweight assembly 30, thereby avoiding the collision between the pulley 31 and the bottom surface of the flat floating body 10. Moreover, through the buffering effect, the impact of the counterweight assembly 30 can be buffered, thereby improving the service life of the counterweight assembly 30.

[0040] In some embodiments, the buffer structure 50 is a spring, which is sleeved on the traction rope 22, and one end of the spring facing away from the counterweight assembly 30 is connected to the bottom surface of the floating body 10. When the pulley 31 moves upward and squeezes the spring, the spring is compressed, generating a force opposite to the squeezing direction of the pulley 31, thereby buffering the impact of the pulley 31. In addition, when the weight 32 moves downward under the action of gravity, under the action of the elastic restoring force of the spring, the spring pushes the counterweight assembly 30 to move downward, and the counterweight assembly 30 obtains more energy and greater kinetic energy, so that the final converted electrical energy and stored energy are more, further improving the energy utilization rate.

[0041] In some embodiments, Figure 4As shown, a plurality of pulleys 31 are arranged at intervals, a plurality of energy conversion assemblies 20 are arranged at intervals, each pulley 31 corresponds to each energy conversion assembly 20, and a plurality of mooring chains 40 are arranged, each mooring chain 40 is wound around each pulley 31, and each mooring chain 40 is connected to the same weight block 32. It can be understood that the energy conversion assembly 20, the pulley 31 and the mooring chain 40 correspond to each other, and the number of energy conversion assemblies 20, the pulley 31 and the mooring chain 40 is the same, but the number of the weight block 32 is set to one, and each mooring chain 40 is connected to the weight block 32.

[0042] By connecting multiple mooring chains 40 to the same weight block 32, compared to connecting multiple mooring chains 40 to multiple weight blocks 32 respectively and multiple weight blocks 32 in a dispersed state, it is equivalent to integrating multiple dispersed weight blocks 32 into a large weight block 32, which can make the mooring system more integrated, lower the center of gravity of the weight block 32, and further improve the stability of the mooring system. At the same time, it can also avoid the multiple dispersed weight blocks 32 from interfering or colliding with each other during the movement process, thereby improving the safety of the mooring system. In addition, by setting multiple mooring chains 40 to connect the same weight block 32, the weight block 32 can be pulled in multiple directions, so that the tension on the weight block 32 is more balanced, and the weight block 32 is prevented from colliding with the pulley 31 or the floating body 10 due to uneven force, thereby further improving the safety of the mooring system.

[0043] Optionally, in the embodiment of the present application, the number of the energy conversion assembly 20, the pulley 31 and the mooring chain 40 are all three, and the weight block 32 is pulled in three directions, thereby further improving the stability of the mooring system. Of course, in other possible implementations, the number of the energy conversion assembly 20, the pulley 31 and the mooring chain 40 can also be four, five, six or more, and the embodiment of the present application does not limit the number of the energy conversion assembly 20, the pulley 31 and the mooring chain 40.

[0044] In some embodiments, the floating body 10 has a receiving cavity 11, and the energy conversion component 20 is arranged in the receiving cavity 11, that is, a protective structure is formed outside the floating body 10, and the protective structure covers the outside of the energy conversion component 20. It can resist the interference of wind and waves on the receiving cavity 11, avoid damage or contamination of the energy conversion component 20, thereby improving the service life of the energy conversion component 20.

[0045] The present application also proposes an ocean floating platform, which includes a new type of heavy block pulley energy storage mooring system. The specific structure of the new type of heavy block pulley energy storage mooring system refers to the above-mentioned embodiment. Since the present ocean floating platform adopts all the technical solutions of all the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0046] In summary, the new type of heavy block pulley energy storage mooring system provided by the present application can use the weight of the counterweight assembly 30 itself to offset the buoyancy of the ocean floating platform in the ocean, effectively reduce the constraint load of the ocean floating platform design, and further reasonably reduce the number of mooring chains 40 in the mooring system and the design load size of each mooring chain 40. Since the design number and design strength of the mooring chains 40 are reduced, the design cost is significantly reduced, which greatly reduces the overall cost of the entire ocean floating platform and effectively reduces the cost. In addition, the counterweight assembly 30 also has the function of acting as a damper. When the ocean floating platform as a whole is affected by extreme wind, wave and current loads, the counterweight assembly 30 can consume the force exerted on the ocean floating platform to ensure the safety and stability of the structure above the sea level. Moreover, by setting up the energy conversion component 20, when the counterweight component 30 falls due to gravity, the traction rope 22 will drive the rotating shaft 21 to rotate, and the generator 23 will convert the rotational kinetic energy of the rotating shaft 21 into electrical energy, thereby realizing the conversion of the gravitational potential energy of the counterweight component 30 into electrical energy, providing additional energy for the overall stability of the mooring system, and the energy conversion efficiency is high and pollution-free, which is conducive to improving energy utilization and environmental benefits.

[0047] The above are only optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
