Description

Technical Field

[0001] The present invention relates to the technical fields of offshore floating platforms and test platforms, and in particular to a mooring self-recovery floating renewable energy hydrogen production omnidirectional angle test platform. Background Art

[0002] Offshore renewable energy hydrogen production technology utilizes abundant renewable energy such as wind energy, solar energy, wave energy, and tidal energy in the marine environment to produce hydrogen based on the principle of electrolyzing water, thereby realizing clean conversion and efficient storage of energy. It can smooth power fluctuations, promote the integration of renewable energy into the energy network, and improve the stability of the power grid, providing an effective technical solution for accommodating offshore renewable energy power and having broad application prospects. The offshore renewable energy hydrogen production system includes a hydrogen production and storage module and an energy conversion and storage module. The hydrogen production and storage module is used to prepare and store hydrogen, and the energy conversion and storage module is used to convert hydrogen energy into electrical energy and can store electrical energy as a flexible regulation resource for the power grid.

[0003] In the prior art, the hydrogen production and storage performance, energy conversion and storage performance of offshore renewable energy hydrogen production systems are mostly tested and verified based on land or nearshore fixed platforms. However, with the development of deep sea areas, traditional offshore renewable energy hydrogen production systems applicable to land and nearshore areas cannot effectively simulate the complex deep sea environment, resulting in a lack of verification of the adaptability, stability, and durability of traditional offshore renewable energy hydrogen production systems on offshore floating platforms, restricting the further development of offshore renewable energy hydrogen production technology. Therefore, there is an urgent need for a floating test platform to explore the operating status and operating effects of offshore renewable energy hydrogen production systems in the offshore moving environment (especially wind, wave, and current). Summary of the Invention

[0004] The applicant of the present invention aims at the above-mentioned disadvantages in the existing production technology and provides a mooring self-recovery floating renewable energy hydrogen production omnidirectional angle test platform with a reasonable structure, which can carry the device to be tested to the deep sea area for testing, so as to effectively verify the operating status and operating effects of the device to be tested in the offshore moving environment of the deep sea.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A mooring self-recovery floating renewable energy hydrogen production omnidirectional angle test platform includes a floating foundation floating on the sea surface. A self-recovery mooring device is cooperatively installed on the top of the floating foundation. An upper box body is concentrically installed on the top of the floating foundation. The upper box body includes a self-recovery mooring device. A rotary device is cooperatively installed on the top of the upper box body. A device to be tested is placed on the rotary device. The device to be tested rotates under the drive of the rotary device, thereby adjusting the angle between the device to be tested and the wave direction.

[0007] The floating foundation stays in the target sea area through the self-recovery mooring device, so that the device to be tested can conduct performance tests in the target sea area.

[0008] As a further improvement of the above technical solution:

[0009] The structure of the upper box body is as follows: it includes a first shell in a cylindrical shape, and an upper deck is fitted and installed at the top of the first shell.

[0010] Several damping plates are evenly spaced along the circumference of the side of the first shell.

[0011] Under the action of the hydraulic power adjustment device, the unfolding angle of a single damping plate is adjusted, so as to adjust the motion damping of the platform in the water.

[0012] The structure of the floating foundation is as follows: it includes a second shell in a bowl shape, a moonpool is arranged in the middle of the second shell, several cabins are arranged inside the second shell, and a working platform is arranged at the top of the second shell.

[0013] The cabins include at least one ballast tank, at least one fresh water tank, and at least one working cabin.

[0014] A control system is fitted and installed in one of the working cabins.

[0015] The structure of the self-recovery mooring device is as follows: it includes an anchor chain, one end of the anchor chain is connected to an anchor, and the other end of the anchor chain is wound around an anchor winch. The anchor winch lowers the anchor to the seabed or retrieves the anchor from the seabed by releasing or winding the anchor chain.

[0016] The self-recovery mooring device further includes a water supply pipe group installed on the floating foundation. A control valve and a water pump are sequentially installed on the water supply pipe group. A nozzle is fitted and installed at the end of the water supply pipe group. The nozzle extends into the sea water and is arranged towards the anchor;

[0017] When the control valve is opened, under the action of the water pump, the water supply pipe group transports external sea water into the nozzle, and sprays water flow to the seabed area around the anchor through the nozzle, so as to reduce the gripping force of the seabed area on the anchor.

[0018] The structure of the slewing device is as follows: it includes a rotating shaft, a slewing test bench is fitted and installed at one end of the rotating shaft, and the other end of the rotating shaft is connected to a slewing driving part. The slewing driving part drives the slewing test bench to rotate through the rotating shaft, so as to meet the test working condition requirements for the all-round angle test of the device to be tested.

[0019] The beneficial effects of the present invention are as follows:

[0020] The structure of the present invention is compact and reasonable, and it is convenient to operate. By setting up an upper box body, a floating foundation and a self-recovery mooring device, it can carry the device to be tested to conduct performance tests in the open sea area, so as to obtain the operating status and operating effect of the device to be tested in the marine motion environment, and can effectively verify the adaptability, stability and durability of the marine renewable energy hydrogen production system on the marine floating platform, which helps the further development of the marine renewable energy hydrogen production technology.

[0021] The present invention also has the following advantages:

[0022] (1) By setting up a second shell in the shape of a bowl, the present invention has the characteristics of low stability and large motion response in wind and waves, and can meet the requirements of the marine test conditions when the device to be tested conducts the power-hydrogen-network-consumption performance test.

[0023] (2) By setting up a damping plate and a corresponding hydraulic power adjustment device, the present invention can make the damping plate contact the water surface, thereby improving the damping of the test platform itself, and further reducing the roll angle and pitch angle of the test platform.

[0024] (3) By setting up a control system, when the maximum value of the real-time tilt angle detected by the sensing system is greater than the tilt angle safety threshold, the present invention can drive the damping plate to unfold and adjust its unfolding angle through the hydraulic power adjustment device, thereby preventing the test platform from tilting further, protecting the safety of the test platform, personnel and equipment, and ensuring the smooth progress of the test.

[0025] (4) By setting up a slewing device, the present invention can drive the device to be tested to make a rotational motion at any angle within the range of 0°-360°, so as to adjust the angle between the device to be tested and the wave direction, and further meet the requirements of the all-round angle working conditions of the marine test of the device to be tested.

[0026] (5) By setting up a water pump, a water supply pipe group and a sprinkler head, the present invention can form a high-pressure water flow to impact the sandy soil around the ship anchor, so as to reduce the grasping force of the seabed sandy soil on the ship anchor, thereby facilitating the recovery of the ship anchor.

[0035] The following combines with the attached drawings to illustrate the specific implementation mode of the present invention.

[0036] The structure and function of the present invention are as follows:

[0037] As Figures 1 - 4 shown, a mooring self-recovery floating renewable energy hydrogen production omnidirectional angle test platform includes a floating foundation 2 floating on the sea surface. A self-recovery mooring device 8 is cooperatively installed on the top of the floating foundation 2. An upper box body 1 is concentrically installed on the top of the floating foundation 2. The upper box body 1 includes the self-recovery mooring device 8. A rotary device is cooperatively installed on the top of the upper box body 1. A device under test 6 is placed on the rotary device. The device under test 6 rotates under the drive of the rotary device, so as to adjust the angle between the device under test 6 and the wave direction; through the self-recovery mooring device 8, the floating foundation 2 stays in the target sea area, so that the device under test 6 conducts performance tests in the target sea area. By setting the upper box body 1, the floating foundation 2 and the self-recovery mooring device 8, the device under test 6 (the offshore renewable energy hydrogen production system in the present invention) can be carried to conduct performance tests in the open sea area, so as to obtain the operating state and working effect of the device under test 6 in the offshore movement environment (especially wind, wave and current).

[0038] The structure of the rotary device is: it includes a rotating shaft 4. One end of the rotating shaft 4 is cooperatively installed with a rotary test bench 5. The other end of the rotating shaft 4 is connected to a rotary driving member. The rotary driving member drives the rotary test bench 5 to rotate through the rotating shaft 4, so as to meet the test working condition requirements for the omnidirectional angle test of the device under test 6. By setting the rotary device, the device under test 6 can be driven to make a rotational movement at any angle within the range of 0° - 360° along the circumferential direction of the rotating shaft 4, so as to adjust the angle between the device under test 6 and the wave direction, and further meet the omnidirectional angle test working condition requirements of the device under test 6 in the offshore test.

[0039] In the present invention, the device under test 6, namely the offshore renewable energy hydrogen production system, adopts an integrated design and is equipped with an offshore hydrogen production, storage module, an energy conversion and storage module, and other functional auxiliary modules. The device under test 6 can be detachably installed on the rotary test bench 5, facilitating subsequent offshore test verification of the electro-hydro-network-consumption performance of the device under test 6.

[0040] As Figure 1 shown, the structure of the upper box body 1 is as follows: It includes a first shell 101 in a cylindrical shape, and an upper deck 102 is fitted and installed at the top of the first shell 101. The upper deck 102 is rotationally fitted with the rotating shaft 4, and the end of the rotating shaft 4 extends above the upper deck 102 and is fitted and installed with the slewing bearing platform 5. The rotary test bench 5 is about one meter or more higher than the top end face of the upper deck 102.

[0041] Several damping plates 3 are evenly spaced along the circumference of the side of the first shell 101. The unfolding angle of a single damping plate 3 is adjusted under the action of a hydraulic power adjustment device, thereby adjusting the motion damping of the platform in the water. By providing the damping plates 3 and the corresponding hydraulic power adjustment device, the unfolding angle of the damping plates 3 is increased, thereby increasing the motion damping of the platform itself in the water, and further reducing the roll angle and pitch angle of the test platform.

[0042] In the present invention, the hydraulic power adjustment device can adopt a hydraulic push rod. By hinging the hydraulic push rod to the side of the first shell 101, the output end of the hydraulic push rod is connected to the corresponding damping plate 3, so that the unfolding angle of the damping plate 3 can be adjusted.

[0043] A single damping plate 3 is installed on the side of the first shell 101 through a hinged assembly, and the hinged assembly is arranged at the middle position of the side of the first shell 101.

[0044] As Figure 3 shown, the structure of the floating foundation 2 is as follows: It includes a second shell 201 in a bowl shape, a moonpool 203 is provided in the middle of the second shell 201, several compartments 204 are provided inside the second shell 201, and a working platform 202 is provided at the top of the second shell 201. By providing the second shell 201 in a bowl shape (i.e., hemispherical), it has the characteristics of low stability and large motion response in wind and waves, and can meet the requirements of the offshore test conditions for the electro-hydro-network-consumption performance test of the device under test 6.

[0045] The compartments 204 include at least one ballast tank, at least one fresh water tank, and at least one working cabin. The ballast tank adjusts the draft depth and the center of gravity position of the floating platform by injecting or discharging seawater, ensuring that the floating platform can maintain a horizontal or required attitude under different sea conditions, preventing tilting or instability, and ensuring operation safety; the fresh water tank is used to store fresh water to provide domestic and production water for the staff on the test platform, meeting the daily needs of personnel and the operation requirements of equipment.

[0046] One of the working cabins is equipped with a control system, and the remaining working cabins are also equipped with a communication system, a navigation system (GPS is used in the present invention), a power system, and a sensor network to maintain the stable operation of the test platform.

[0047] The sensing system includes several motion and attitude sensors installed on the test platform. According to the feedback signals of the sensing system, the control system adjusts the water volume in the ballast tank and the deployment angle of the damping plate 3 to make the attitude of the test platform meet the test requirements of the device 6 to be tested.

[0048] As Figure 4 shown, the structure of the self-recovery mooring device 8 is as follows: it includes an anchor chain 802. One end of the anchor chain 802 is connected to an anchor 803, and the other end of the anchor chain 802 is wound around an anchor winch 801. The anchor winch 801 lowers the anchor 803 to the seabed or retrieves the anchor 803 from the seabed by releasing or winding the anchor chain 802. The anchor 803 uses a large-grip anchor, which can provide a stable traction force for the test platform after being lowered. By setting the anchor winch 801 and the anchor chain 802, the anchor winch 801 can automatically wind or release the anchor chain 802 under the control of the control system, thereby realizing the recovery or lowering of the anchor 803.

[0049] In the present invention, a chain stopper 804 is also arranged beside the anchor winch 801. The chain stopper 804 is used to fix the anchor chain 802 and transfer the tension generated by the anchor chain 802 to the test platform, thereby protecting the anchor winch 801.

[0050] As Figure 4 shown, the self-recovery mooring device 8 also includes a water supply pipe group 806 installed on the floating foundation 2. A control valve 807 and a water pump 805 are sequentially installed on the water supply pipe group 806. The end of the water supply pipe group 806 is fitted with a nozzle 808, and the nozzle 808 extends into the sea water and is arranged towards the anchor 803. When the control valve 807 is opened, under the action of the water pump 805, the water supply pipe group 806 transports external sea water into the nozzle 808, and sprays the water flow to the seabed area around the anchor 803 through the nozzle 808, thereby reducing the grip of the seabed area on the anchor 803. The nozzle 808 uses a high-pressure nozzle, which can generate high-pressure water flow to impact the sandy soil geology in the seabed area around the anchor 803, so as to reduce the grip of the seabed sand on the anchor 803 and facilitate the recovery of the anchor 803.

[0051] In the present invention, the anchor chain 802 and the water supply pipe group 806 both extend into the sea water from the working platform 202 through the moonpool 203. In order to facilitate the positioning of the nozzle 808 and the deployment and recovery of the water supply pipe group 806, the anchor chain 802 and the water supply pipe group 806 are tied and fixed together through several connecting devices 7, and the connecting device 7 can adopt a cable tie.

[0052] The working process of the present invention is as follows:

[0053] S1. The test platform sails to the upper part of the target mooring point in the test sea area under tow traction.

[0054] S2. During the movement of the test platform, the attitude of the test platform is detected in real time through the sensing system and transmitted back to the control system. According to the feedback signal of the sensing system, the control system adjusts the attitude of the test platform to ensure the smooth and safe conduct of the test.

[0055] S2.1. The safety threshold of the inclination angle is pre-stored in the control system. When the maximum value of the real-time inclination angle detected by the sensing system is less than or equal to the safety threshold of the inclination angle, the control system adjusts the attitude of the test platform only by adjusting the water volume in the ballast tank. When the maximum value of the real-time inclination angle detected by the sensing system is greater than the safety threshold of the inclination angle, the control system first adjusts the water volume in the ballast tank. After the adjustment is in place, the damping plate 3 is driven to unfold and its unfolding angle is adjusted through the hydraulic power adjustment device, so as to prevent the test platform from further tilting, protect the safety of the test platform, personnel and equipment, and ensure the smooth conduct of the test.

[0056] S3. The water supply pipe group 806 at the connection of the nozzle 808 and the anchor chain 802 at the connection of the ship anchor 803 are tied and fixed together through the connecting device 7. The ship anchor 803 and the water supply pipe group 806 are put into the sea through the moonpool 203. The anchor winch 801 slowly releases the anchor chain 802 and the water supply pipe group 806, and ties and fixes the anchor chain 802 and the water supply pipe group 806 together through several connecting devices 7 until the ship anchor 803 touches the bottom and is fixed. The anchor winch 801 slowly and slightly winds or releases the anchor chain 802 to adjust the tension of the anchor chain 802 to ensure the sufficient stability of the test platform.

[0057] S4. The device to be tested 6 is installed on the rotary test bench 5, and the device to be tested 6 is turned on, and the device to be tested 6 conducts the electric-hydro-network-consumption test.

[0058] S5. The rotary drive member drives the rotating shaft 4 to rotate, so as to drive the device to be tested 6 to rotate through the rotary test bench 5, and then adjust the angle between the device to be tested 6 and the wave direction to carry out a 360° all-round working condition test.

[0059] S6. During the test, when the maximum value of the real-time tilt angle detected by the sensing system is greater than the tilt angle safety threshold, the control system first adjusts the water volume in the ballast tank. After the adjustment is in place, it then drives the damping plate 3 to unfold and adjust its unfolding angle through the hydraulic power adjustment device, thereby preventing the test platform from tilting further, protecting the safety of the test platform, personnel and equipment, and ensuring the smooth progress of the test;

[0060] S7. After the device under test 6 finishes the test, the control valve 807 is opened, the water pump 805 is started, external seawater is inhaled through the water supply pipe group 806, and high-pressure water flow is generated through the nozzle 808. The high-pressure water flow is sprayed onto the seabed sand around the anchor 803, reducing the grasping force of the sand on the anchor 803. Subsequently, the anchor winch 801 winds the anchor chain 802 to recover the anchor 803, the water supply pipe group 806 and the nozzle 808 until the anchor 803 and the water supply pipe group 806 are recovered onto the working platform 202.
