[0002] At present, offshore photovoltaic technology has not yet been perfected and can only be developed in shallow sea areas. The traditional method is to drive piles in the water. This method is costly and difficult to construct. It has poor adaptability to large tidal range problems in complex sea areas, but the stability of the photovoltaic structure is good and not easy to be damaged. At present, many photovoltaic projects use a mooring system, that is, an anchor chain plus a mooring foundation.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Example 1

[0032] like Figure 1-Figure 3 As shown, a water photovoltaic mooring equipment includes a buffer component, a sliding component, an adaptive retractable component and a vertically arranged pile frame group, a vertical open hole sliding frame 2.3 is arranged on the pile frame group, a buffer component is installed at each of the upper and lower ends of the open hole sliding frame 2.3, the sliding component is slidably installed in the open hole sliding frame 2.3, and is located between two buffer components, the sliding component moves up and down in the open hole sliding frame 2.3 as the sea level rises or falls, the sliding component moves upward to the highest point and can contact the upper buffer component, the sliding component moves downward to the lowest point and can contact the lower buffer component, the sliding component is connected to the adaptive retractable component, the adaptive retractable component is connected to the photovoltaic support 3, as the sea level rises or falls, the photovoltaic support 3 rises or falls under the action of buoyancy, drives the sliding component to rise or fall, and the adaptive retractable component is retracted or released accordingly.

[0033] The pile frame group is composed of four groups of vertical support arms 2.1 arranged crosswise, each group of vertical support arms 2.1 is provided with two parallel vertical plates 2.2, each vertical plate 2.2 is provided with an open hole sliding frame 2.3 along its length direction, and each open hole sliding frame 2.3 is installed with a sliding component.

[0034] The sliding assembly includes a slider 2.4 and a slider ear plate 2.5. A slider ear plate 2.5 is installed at each end of the slider 2.4. The slider 2.4 is located in a perforated sliding frame 2.3. The slider ear plates 2.5 are located on both sides of the vertical plate 2.2 where the perforated sliding frame 2.3 is located, so as to limit the slider 2.4 in the perforated sliding frame 2.3 and enable it to move up and down.

[0035] The adaptive retractable assembly comprises a double-ended sliding connection shaft 2.11, a tension dynamometer 2.6, a rotating motor 2.12, a mooring rope 2.7 and a connecting shackle 2.8. The double-ended sliding connection shaft 2.11 is driven to rotate by the rotating motor 2.12. Specifically, each of the two ends of the double-ended sliding connection shaft 2.11 is connected to the rotating motor 2.12, or one end of the double-ended sliding connection shaft 2.11 is connected to the rotating motor 2.12. The opposite ends of the double-ended sliding connection shaft 2.11 respectively pass through a slider ear plate. 2.5 is inserted into the corresponding slider 2.4 and is rotationally connected to the slider 2.4. The rotating motor 2.12 is installed on the slider 2.4 on the corresponding side. The two mooring cables 2.7 are sequentially wound around the double-headed sliding connecting shaft 2.11. The ends of the two mooring cables 2.7 are connected together through a connecting shackle 2.8. The connecting shackle 2.8 is used to connect the photovoltaic support 3. A tension dynamometer 2.6 is installed on each of the two mooring cables 2.7. The mooring cables are made of corrosion-resistant polyester cables with high mooring strength. The rotating motor 2.12 adjusts the length of the mooring cables by controlling the rotation of the double-headed sliding connecting shaft 2.11. This adaptive retractable assembly enables the photovoltaic support 3 to realize the function of intelligently retracting and releasing the mooring cables according to the change in water depth.

[0036] The buffer assembly includes an arc-shaped gasket 2.9, a buffer spring 2.10 and a spring dynamometer. The buffer springs 2.10 in the two buffer assemblies are respectively installed on the upper end surface and the lower end surface of the perforated sliding frame 2.3. The arc-shaped gasket 2.9 is installed on the buffer spring 2.10. The spring dynamometer is connected to the buffer spring 2.10 to test the force exerted on the buffer spring 2.10. The function of the buffer spring is to relieve the impact force of the sliding assembly rising or falling through its own compression to protect the overall structure.

[0037] Furthermore, the tension dynamometer 2.6, the spring dynamometer and the rotary motor 2.12 are connected to a control system.

[0038] Example 2

[0039] like Figure 1 As shown, this embodiment provides a mooring system, including multiple prefabricated pipe piles 1, photovoltaic supports 3 and the water photovoltaic mooring equipment 2 described in Example 1, multiple prefabricated pipe piles 1 are arranged in a matrix and vertically inserted into the mud surface, one water photovoltaic mooring equipment 2 is welded to the upper end of each prefabricated pipe pile 1, and a photovoltaic support 3 is installed between four water photovoltaic mooring equipment 2.

[0040] The working process of the mooring system is as follows:

[0041] like Figure 4As shown, when the initial water level rises, the photovoltaic support 3 rises with the rise of the water level. At this time, the slider 2.4 does not touch the upper arc-shaped gasket 2.9, the spring dynamometer does not detect the spring threshold (i.e., less than the spring threshold), the tension dynamometer 2.6 measures a tension less than the sliding threshold tension, the connecting shackle 2.8 is not blocked, and the photovoltaic support 3 drives the sliding assembly and the adaptive retractable assembly to slide upward.

[0042] When the water surface rises rapidly and causes the photovoltaic support 3 to rise sharply, the slider 2.4 touches the upper arc-shaped gasket 2.9, the spring dynamometer detects the spring threshold, the tension dynamometer 2.6 measures a tension greater than the sliding threshold tension, and the rotary motor 2.12 starts to rotate forward, driving the mooring rope 2.7 to extend in an adaptive adjustment.

[0043] When the water level drops, the photovoltaic support 3 drops. At this time, the tension measured by the tension force gauge 2.6 is less than the sliding threshold tension, the connecting shackle 2.8 is unobstructed, and the photovoltaic support 3 drives the sliding assembly and the adaptive retractable assembly to slide downward. At the same time, the rotating motor 2.12 starts to rotate in the opposite direction until the mooring rope 2.7 returns to its original unstretched length and the rotating motor 2.12 stops rotating.

[0044] When the water surface drops below the lowest point, the slider 2.4 touches the arc-shaped gasket 2.9 below, the spring dynamometer detects the spring threshold, the tension dynamometer 2.6 measures the tension greater than the sliding threshold tension, and the rotating motor 2.12 starts to rotate forward, realizing the adaptive adjustment and extension of the mooring rope 2.7. During the entire process of water depth change, the tension dynamometer 2.6 monitors the tension in real time, and the spring dynamometer monitors the compression state of the spring in real time. These monitoring data are transmitted to the rotating motor 2.12 through the control system, so that it can make timely adjustments according to the actual water level.

[0048] Step 2, welding and installation of the water photovoltaic mooring equipment 2: weld the pile frame group of the water photovoltaic mooring equipment 2 to the upper end of the prefabricated pipe pile 1, and adjust the state of the spring dynamometer and the buffer spring 2.10 to adapt to different water depth changes.

[0049] Step 3, installation of sliding assembly and photovoltaic support 3: install the slider 2.4 of the sliding assembly into the open hole sliding frame 2.3 of the pile frame group, and the slider ear plate 2.5 is stuck outside the open hole sliding frame 2.3 to ensure that the sliding assembly can slide freely up and down, and install the photovoltaic support 3 on the connecting buckle 2.8 at the end of the mooring rope 2.7.

[0050] Step 4, installation of tension dynamometer 2.6 and spring dynamometer: install tension dynamometer 2.6 on mooring rope 2.7 near connecting shackle 2.8, install spring dynamometer on buffer spring 2.10, connect control system, ensure that the system can monitor the values ​​of tension dynamometer 2.6 and spring dynamometer in real time, and control the operation of rotating motor 2.12.

[0051] Step 5, debugging and testing: debug the entire mooring system, test its adaptability and intelligent adjustment performance under different water depth conditions, and verify the rising and falling mechanism of the photovoltaic support 3 and the adaptive retractable function of the adaptive retractable component by simulating different sea conditions.
