Description

Technical Field This invention belongs to the field of floating photovoltaic mooring and anchoring technology, and specifically relates to a mooring platform and mooring method for a floating photovoltaic system. Background Technology

[0001] Constructing floating photovoltaic systems on the surface of pumped-storage reservoirs can avoid occupying land resources, reduce reservoir water evaporation, lower the temperature of the solar panels, and improve power generation efficiency, making it a clean and efficient way to produce electricity. However, the water level of pumped-storage reservoirs changes frequently and significantly, which places high demands on the adaptability of the mooring and anchoring system.

[0002] Existing mooring methods for floating systems with large water level fluctuations can be broadly categorized into three technical approaches based on their principles: First, using elastic mooring lines, such as incorporating a spring device in one section of the line, utilizing the spring's own elasticity to adapt to water level fluctuations. This method is simple and low-cost, but the elastic mooring line is prone to fatigue under frequent water level changes, potentially resulting in poor durability. Second, installing limiting devices such as rails, cableways, and columns on the reservoir wall, then engaging the edge of the floating system with these devices, or connecting the floating system to the columns via pulleys, collars, or other devices. When the water level changes, these devices restrict the movement of the floating system's edge along the limiting devices, thus limiting its drift. However, these limiting devices are mostly installed on the reservoir wall or bottom, which can damage the reservoir's impermeable layer during construction, making them unsuitable for pumped-storage power stations with high impermeability requirements. Thirdly, rope winding and unwinding devices, such as electric rope winding and unwinding machines and winches, are used in conjunction with rope tension sensors. When water level changes cause the rope to slack or tighten, the electric rope winding and unwinding machine winds up or unwinds the rope, ensuring the mooring line maintains an appropriate length. For example, Chinese patent (CN217260586U) uses a structure with winches, pulley blocks, and steel wire ropes fixed on both banks. The winches are installed at high positions on both banks, and the steel wire ropes are wound and unwound according to the rise and fall of the reservoir's water level, achieving the purpose of adapting the photovoltaic array to changes in the reservoir's water level. This method has good durability and does not damage the reservoir's seepage prevention layer, making it one of the promising methods for engineering applications. However, this method relies on the winches to wind and unwind the steel wire ropes, requiring precise synchronous control of several winches. Otherwise, asynchronous rope winding and unwinding by multiple winches may lead to instability of the buoy and breakage of some mooring lines. In addition, this method cannot actively adjust the buoy's azimuth angle, and the photovoltaic panels it carries cannot track the sun's direction to maximize power generation.

[0003] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0004] To address the aforementioned issues, this invention proposes a mooring platform for a floating photovoltaic system, comprising: a supporting outer frame, the lower surface of which is coaxially connected to the upper surface of a floating body, and a photovoltaic panel mounted on the upper surface of the floating body. The upper surface of the load-bearing outer frame is provided with several slide rails connected end to end. The side wall of the slide rail is provided with a slot in the same direction. The slot slides engage with the slider. The side wall of the slider is connected to the winch by a rope. The slider includes an upper positioning block, a lower positioning block, a connecting rod, and a drive assembly. The side wall of the upper positioning block is provided with rollers that fit against the upper surface of the slide rail. The upper positioning block is connected to one end of the connecting rod, and the other end of the connecting rod extends into the slot and is connected to the positioning block. The outer wall of the connecting rod located in the slot is slidably sleeved with the lower positioning block. The drive assembly is connected to the lower positioning block to drive the lower positioning block to move closer to or away from the slot opening.

[0005] Furthermore, there are four slide rails, which are connected end to end in sequence, and adjacent slide rails are arranged perpendicularly.

[0006] Furthermore, the slide rail includes two parallel and spaced rails with an inverted L-shaped structure, forming a groove between the two rails, and the width of the positioning block is greater than the spacing of the groove opening.

[0007] Furthermore, the upper positioning block contains an electromagnet and a power source electrically connected to the electromagnet, while the lower positioning block forms a magnetic connection with the electromagnet.

[0008] Furthermore, tension sensors are installed on several of the ropes.

[0009] Furthermore, an angle sensor is installed on the upper surface of the float body.

[0010] This invention also discloses a mooring method for a floating photovoltaic system, including a mooring platform for the floating photovoltaic system as described above, and further including: a water level sensor. The mooring method includes: Water level data is obtained based on a water level sensor, rope tension data is obtained based on a tension sensor, and tilt angle data of the floating body is obtained based on a tilt angle sensor. Based on water level data, rope tension data, and tilt angle data, the winch and slider are activated to adjust the main body of the float to be in operation. Obtain the solar azimuth angle, activate several sliders to change their position relative to the slide rails until the yaw deviation angle of the photovoltaic panel is less than the second set value, and complete the mooring operation.

[0011] Furthermore, when the main body of the float is in operation, the deviation between the rope tension data and the first set value is within ±5%, and the tilt angle data is less than the third set value.

[0012] Furthermore, based on water level data, rope tension data, and tilt angle data, the winch and slider are activated to adjust the main body of the float into operational status, specifically including: Based on water level data and rope tension data, when it is observed that the water level and rope tension data continuously change monotonically for more than a set time interval, several winches are started to adjust the length of several ropes until the rope tension data of several ropes deviates from the first set value within ±5%, and the main body of the float is adjusted to be in working condition again. Alternatively, based on tilt angle data and rope tension data, when the tilt angle data is observed to be greater than the third set value or the rope tension data exceeds the first set value by 20%, several sliders are activated to change the position relative to the slide rails until the tilt angle of the float is less than the third set value, and the main body of the float is adjusted to be moored again.

[0013] Furthermore, the third setting is 5° to 10°.

[0014] Furthermore, it also includes a central control device, which is used to acquire historical water level change data, real-time wind speed and wave height information, and to pre-adjust the slider.

[0015] Compared with the prior art, the embodiments of the present invention have at least the following advantages: 1. The mooring platform of the floating photovoltaic system of the present invention dynamically adjusts the length of the mooring rope according to changes in water level, i.e., the "water level change mode". Based on the water level change mode, a "maximum power generation mode", i.e., the solar tracking mode, is further set. The connection point between the mooring rope and the floating platform is set on a movable slider. By driving each slider to slide on the slide rail, the mooring rope connected to it moves, changing the direction of the rope tension, generating torque on the main body of the floating body, driving the supporting outer frame and the main body of the floating body to rotate with the sun's position, thereby maximizing the power generation of the power generation equipment carried by the floating body.

[0016] 2. When a winch malfunctions or control asynchrony causes uneven lengths of the mooring ropes at the four corners of the float, resulting in float instability, the mooring enters a "balance adjustment mode." This mode involves an emergency drive slider moving towards the lower corner of the float to increase the tension in a specific direction, thereby maintaining the stability of the four corners of the float and ensuring balanced force on the mooring ropes. This guarantees the stability of the power generation equipment on the main body of the float and the safety of the mooring, thus improving the service life of the floating system.

[0017] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures pointed out in the description and the drawings. Attached Figure Description

[0021] The following description provides many different embodiments for implementing various features of the invention. The components and arrangements described in the following specific examples are for succinct illustration only and are not intended to limit the invention.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] This invention provides a mooring platform for a floating photovoltaic system. Figure 1 A schematic diagram of the mooring platform for a floating photovoltaic system according to an embodiment of the present invention is shown, with reference to... Figure 1 The mooring platform for the floating photovoltaic system includes: a supporting outer frame 1, the lower surface of which is coaxially connected to the upper surface of the floating body 2; in this embodiment, the supporting outer frame 1 is a hollow square structure, and the center position of the upper surface of the floating body 2 is coaxially arranged with the hollow position of the supporting outer frame 1. Correspondingly, photovoltaic panels and other power generation equipment are installed at the center position of the upper surface of the floating body 2. The upper surface of the supporting outer frame 1 is provided with a plurality of slide rails 3 connected end to end. The slide rails 3 are provided with grooves 302 on the upper side wall opposite to the supporting outer frame 1. The grooves 302 slide and engage sliders 4. The side walls of the sliders 4 are respectively connected to one end of a plurality of ropes 5. The other ends of the ropes 5 are respectively connected to the output ends of a plurality of winches 6.

[0024] For details, please refer to Figure 2 The slider 4 includes an upper positioning block 401, a lower positioning block 402, a connecting rod 406, and a driving assembly. The upper positioning block 401 has a roller 403 on its side wall that fits against the upper surface of the slide rail 3. The upper positioning block 401 is connected to one end of the connecting rod 406, and the other end of the connecting rod 406 extends into the slot 302 and is connected to the positioning block 407. The outer wall of the connecting rod 406 located in the slot 302 is slidably sleeved with the lower positioning block 402. The driving assembly is connected to the lower positioning block 402 to drive the lower positioning block 402 to move closer to or away from the slot opening of the slot 302.

[0025] In the example, the side wall of slider 4 is provided with a rope block, and the rope loop is used to connect to one end of rope 5.

[0026] This invention provides a mooring platform for a floating photovoltaic system. Several winches 6 control the lengths of several ropes 5, thereby allowing for vertical position control of the supporting outer frame 1 and the floating body 2. Under the control of several slide rails 3 and corresponding sliders 4, the positions of the connection points between the ropes 5 and the supporting outer frame 1 are changed. This satisfies the technical requirement of rotating the supporting outer frame 1 and the floating body 2 while keeping the lengths of the ropes 5 constant. Furthermore, the sliders 4 assist the winches 6 in synchronously adjusting the supporting outer frame 1, ensuring balanced force distribution on the winches 6. This improves the compatibility and service life of the winches 6 and the corresponding ropes 5, and enhances the stability of the photovoltaic panels and other power generation equipment on the floating body 2.

[0027] In this embodiment, the square-structured load-bearing outer frame 1 is used as an example for explanation. There are four slide rails 3. The four slide rails 3 are connected end to end in sequence, and the adjacent slide rails 3 are arranged vertically. Each slide rail 3 is provided with a slot 302 in the same axis. The four slots 302 correspond to and slide to engage the four sliders 4. Since the adjacent slide rails 3 are arranged vertically, the sliding range of the slider 4 is limited to the corresponding slide rail 3, which prevents the slider 4 from sliding onto the adjacent slide rail 3, thus reducing the overall adjustment difficulty and stability of the device.

[0028] It should be noted that, in actual use, the four sliders 4 are connected to one end of the four ropes 5 respectively, and the other end of the four ropes 5 are connected to the output end of the four winches 6 respectively. The four winches 6 are all located on the shore, and the altitude of the winches 6 is higher than the water level and the height of the main body of the floating body 2. The installation position of the four winches 6 remains fixed.

[0029] The lengths of the four ropes 5 are controlled by four winches 6, thereby adjusting the magnitude of the rope tension data of the four ropes 5. By controlling the position of the four sliders 4, the position of the mooring point and the direction of the rope tension data are changed, thereby achieving the adjustment of the direction of the rope tension data of the rope 5.

[0030] For details, please refer to Figure 3 In this embodiment, the slide rail 3 includes two parallel and spaced rails 301. The rails 301 have an inverted L-shaped structure, and a U-shaped groove 302 is formed between the two rails 301. The width of the positioning block 402 is greater than the spacing of the groove opening of the groove 302, so as to limit the positioning block 402 to always be located in the inner cavity of the groove 302. As the positioning block 402 approaches the groove opening of the groove 302, the positioning block 402 and the groove 302 are pressed together, thereby limiting the relative position of the slide rail 3 and the slider 4.

[0031] It should be noted that the side wall of the positioning block 401 is provided with two rollers 403, and the two rollers 403 are respectively attached to the two rails 301.

[0032] In this embodiment, the upper positioning block 401 is equipped with an electromagnet 404 and a power supply 405 electrically connected to the electromagnet 404. The lower positioning block 402 is magnetically connected to the electromagnet 404. The power supply 405 controls whether the electromagnet 404 forms a magnetic field. When the electromagnet 404 is energized, it generates a magnetic force that attracts the lower positioning block 402 to move along the connecting rod 406 towards the side closer to the upper positioning block 401. The lower positioning block 402 presses against the rail 301. Based on the friction between the lower positioning block 402 and the rail 301, the relative position of the slider 4 and the corresponding rail 3 is defined. When the power supply 405 and electromagnet 404 are de-energized, the lower positioning block 402 is subjected to its own gravity and moves along the connecting rod 406 away from the upper positioning block 401 until the lower positioning block 402 and the positioning block 407 come into contact. By driving the two rollers 403, the relative position of the slider 4 and the corresponding slide rail 3 is changed, which meets the technical requirement of flexibly changing the position of the slider 4.

[0033] Correspondingly, each of the four ropes 5 is equipped with a tension sensor 8, which is used to measure the force at each point in real time. This allows for adjustment of the connection position between the slider 4 and the slide rail 3 during the process of force changes on the ropes 5, thereby achieving balance and adjustment of the force on the four winches 6 and the four ropes 5.

[0034] In addition, an angle sensor is provided on the upper surface of the float body 2 to measure the tilt angle of the float body 2 in real time. This allows for adjustment of the connection position between the slider 4 and the slide rail 3 during changes in the tilt angle, thereby improving the overall stability of the float body 2.

[0035] The present invention also discloses a mooring method for a floating photovoltaic system, including a mooring platform for the floating photovoltaic system as described above, and further including: a water level sensor 7; Water level data is acquired based on water level sensor 7 for real-time monitoring of water surface height; force data of rope 5 is acquired based on tension sensor 8; and tilt angle data of floating body 2 is acquired based on tilt sensor. Based on water level data, force data, and tilt angle data, the winch 6 and slider 4 are started to adjust the main body 2 of the float to the working state; the solar azimuth angle and irradiance data of the photovoltaic panel are obtained, and several sliders 4 are started to change their position relative to the slide rail 3 until the yaw deviation angle of the photovoltaic panel is less than the second set value, thus completing the mooring operation.

[0036] It should be noted that the yaw deviation angle of the photovoltaic panel refers to the azimuth angle corresponding to the horizontal projection of the normal direction of the photovoltaic panel onto the ground, and the horizontal angle between it and the real-time solar azimuth angle.

[0037] Furthermore, when the float body 2 described in this application is in operation, the deviation between the rope tension data of the rope 5 and the first set value is within ±5%, and the tilt angle data is less than the third set value.

[0038] In this embodiment, when the deviation of the rope tension data of several ropes from the first set value does not exceed ±5%, the water level data and rope tension data do not undergo monotonic changes exceeding the set time interval, and the relative standard deviation of the water level data and rope tension data within the set time interval is less than or equal to 1%, the main body of the float is defined as being in a "moderate mooring state".

[0039] It should be noted that, based on the moderate mooring state of this application, the main body of the floating body will also have a loose mooring state and a tight mooring state. The loose mooring state means that the rope tension data is less than the first set value and the deviation from the first set value is greater than 5%. The tight mooring state means that the rope tension data is greater than the first set value and the deviation from the first set value is greater than 5%.

[0040] When the tilt angle of the main body of the float is less than the third set value, the main body of the float is defined as being in a "stable state". When the main body of the float simultaneously meets the requirements of moderate mooring state and stable state, it indicates that the main body of the float is in an operational state.

[0041] For example, the time interval is set to 5 minutes.

[0042] This application controls the floating body 2 through three modes, including: water level change mode, maximum power generation mode, and balance regulation mode. When, based on water level data and rope tension data, it is observed that the water level and rope tension data continuously change monotonically for more than a set time interval, it is determined that the pumped storage power station will pump or release water, and a corresponding water level change mode is adopted; several winches 6 are started to adjust the length of several ropes 5 until the deviation of the rope tension data of several ropes 5 from the first set value is within ±5%, and the float body 2 is adjusted to be in a moderate mooring state again; based on the deviation of the first set value within ±5%, the risk of mooring slack or excessive tightness of the ropes is reduced.

[0043] Based on the tilt angle data and rope tension data, when the tilt angle data is observed to be greater than the third set value, it is determined that the winch may have malfunctioned or the control may be out of sync, and the balance adjustment mode is entered; several sliders 4 are started to change the position relative to the slide rails 3 until the tilt angle of the float is less than the third set value, and the float body 2 is adjusted to return to a stable state.

[0044] When the observed water level and rope tension do not exhibit monotonic changes exceeding a set time interval, it indicates that the pumped storage power station is not pumping or releasing water. Furthermore, if the standard deviation of both water level and rope tension within the set time interval does not exceed 1%, indicating the absence of severe waves, the system enters the maximum power generation mode, signifying that the main floating body 2 is in operation. Based on the solar azimuth angle, adjustments can be made until the yaw deviation angle of the photovoltaic panels is less than the second set value, thus completing the mooring operation.

[0045] For example, the third setting value is 5° to 10°.

[0046] In addition, it also includes a central control device, which is used to acquire historical water level change data, real-time wind speed and wave height information, and to pre-adjust slider 4.

[0047] The method proposed in this invention, based on the dual control of the winch 6 and the slider 4, meets the daily height adjustment of the floating body 2 through the water level change mode, so as to be suitable for the routine operation of pumped storage power station for pumping and releasing water. Based on the water level change mode, a balance adjustment mode is further set up to deal with accidents such as winch 6 failure or control asynchrony, and to obtain real-time data on the rope tension of different ropes 5 and the tilt angle of the main body 2 of the float; especially in rainy or stormy weather, water waves can easily affect the stability of the main body 2 of the float; when it is determined that the tilt angle of the first sidewall is greater than the third set value, the slider 4 on the sidewall adjacent to the first sidewall is adjusted to slide away from the first sidewall, so as to ensure the stability of the main body 2 of the float and readjust the balanced force between the winches 6, so as to avoid the capsizing of the main body 2 of the float and mooring failure; to realize the control of platform height and azimuth angle, and meet the use in complex environments.

[0048] Based on the water level change mode, a maximum power generation mode is further set. In scenarios where the water level is stable and no safety instability accidents occur, the four sliders 4 can be driven to move clockwise or counterclockwise in a unified manner, so that the mooring force forms a resultant torque on the main body of the float 2, driving it to rotate in a specific direction to track the sun's position and improve the power generation efficiency of photovoltaic panels and other power generation equipment.

[0049] The mooring platform proposed in this invention combines a square-structured floating body 2, four sliding rails 3 forming a ring structure, and four sliding blocks 4. Based on the dynamic adjustment of the mooring rope length when the water level changes, it achieves a mooring solution integrating "attitude adjustment, instability correction, and rope length adaptation" through structural optimization, coordinated control, and functional expansion.

[0050] To better explain the mooring method of this application, an example is given, using a square-structured floating body 2 as an example; refer to Figure 4 Under normal circumstances, the main body 2 floats on the water surface and the angle between it and the water surface is less than the third set value. The rope tension data of the four ropes 5 deviates from the first set value by no more than ±5%. The four sliders 4 are located in the middle of the four slide rails 3 respectively. The four winches 6 are located in the northwest, southwest, northeast and southeast directions of the main body 2 respectively. The third set value is set to 5°.

[0051] When the water level rises or falls rapidly, the water level change mode should be used. For anchor points located on the shore, when the water level rises, the winch 6 should be controlled to retract the rope 5; when the water level falls, the winch 6 should be controlled to release the rope 5.

[0052] During a rapid drop in water level, if the winch 6 on one side releases rope 5 later than expected, the tension in rope 5 at that connection point will increase sharply, causing the float 2 to rise on that side and tilt as a whole. In this situation, a balance adjustment mode should be used. (Reference) Figure 5 When the water level drops, the release of rope 5 from the northwest corner winch 6 lags behind, causing a sudden increase in the tension of rope 5. The northwest corner of the float body 2 tilts upwards, triggering a balance adjustment mode. While adjusting the other three winches 6 to slow the release of rope 5, the slider 4 at the southwest corner moves south and the slider 4 at the northeast corner moves east, increasing the tension of rope 5 corresponding to the winches 6 in the southwest, northeast, and southeast directions. This rebalances the overall force on the device until the tilt angle of the float body 2 is less than or equal to 5°, at which point the sliders 4 in the southwest, northeast, and southeast directions stop moving. This timely torque balance is then restored, and normal adjustment is resumed, protecting the northwest corner winch 6 and rope 5, improving the overall safety of the device, and enhancing the stability of the float body 2.

[0053] Meanwhile, for the maximum power generation mode, refer to Figure 4 Under normal conditions, the sun rises in the east and sets in the west, and the photovoltaic panels installed on the upper side wall of the main floating body 2 face southeast; (Reference) Figure 6 In Figure a on the left, as the sun moves, with the four winches 6 limiting the length of their corresponding ropes 5, the slider 4 at the northwest corner moves towards the west corner of the main body 2, the slider 4 at the northeast corner moves towards the north corner of the main body 2, the slider 4 at the southeast corner moves towards the east corner of the main body 2, and the slider 4 at the southwest corner moves towards the south corner of the main body 2. The tension in the ropes generates a rotational torque on the float, thus causing the main body 2 to rotate clockwise, driving the float to... Figure 6 The state shown in Appendix b on the left side of the middle figure ensures that the deviation between the normal direction of the photovoltaic panel and the solar incident angle is less than the second set value, thus completing the mooring operation.

[0054] In practical applications, the control of slider 4 and winch 6 also includes a central control device. The central control device introduces an LSTM neural network prediction model, which can predict the tension change trend of mooring ropes at each corner in advance by acquiring historical water level change data, real-time wind speed and wave height information, and drive slider 4 to move to the "pre-compensation position" in advance, changing "passive correction" to "active prevention" and further reducing the risk of instability.
