Description

Technical Field

[0001] The utility model relates to the technical field of offshore photovoltaics, and in particular to an offshore photovoltaic pile foundation guide frame and an offshore photovoltaic piling device. Background Art

[0002] As the country's new energy power generation projects enter a stage of rapid development, various types of power generation projects are increasing, and land resources are becoming increasingly scarce. Among them, offshore new energy power generation projects will become the main battlefield in the future.

[0003] At present, the foundations of offshore photovoltaic projects are mostly prestressed concrete pipe piles or steel pipe piles, and the photovoltaic brackets are basically hoisted as a whole. In the process of fixing the photovoltaic bracket installation, the position and verticality accuracy of the pile foundation are very high. Any deviation will affect the overall hoisting of the bracket and components, affecting the component layout and power generation efficiency. However, in actual engineering applications, in complex offshore environments, the current pile foundation construction is to directly carry out pile foundation construction operations such as pile pressing after rough positioning through the positioning system on the pile-driving ship. The pile position coordinates, pile body verticality and elevation are not strictly controlled. When there are large deviations in each group of several piles or the deviation exceeds the design allowable deviation, the overall hoisting of the bracket and components will not be possible, which seriously affects the construction efficiency.

[0004] For example, in the construction of honeycomb-shaped offshore photovoltaic pile foundations, a single group of offshore photovoltaics requires six pile foundations, and the connecting lines of the six pile foundations form a regular hexagon. With the current pile foundation positioning method, it is easy for some pile foundations to fail to meet the specifications, design and on-site construction requirements, resulting in large errors, leading to rework of prefabricated pile foundations, and repeated compression and pulling will disturb or even damage the foundation, resulting in low installation efficiency and difficulty in ensuring the quality of engineering construction, affecting the overall construction and installation qualification rate of the project.

[0005] Therefore, how to ensure the construction positioning accuracy of each pile foundation of each group of offshore photovoltaics and ensure the quality of the project is a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

The second connecting plate 122 is perpendicular to the first connecting plate 121, and both sides of the second connecting plate 122 are respectively fixed to the outer circumferential surface of the guide cylinder 13 and the inner side of the third connecting plate 123, so that the second connecting plate 122 and the two first connecting plates 121 form an "I"-shaped structure to ensure structural strength.

[0044] A fourth connecting plate 124 is detachably fixedly connected to the side of the third connecting plate 123 facing away from the second connecting plate 122 by a connecting bolt 125, and the fourth connecting plate 124 is adapted to the shape of the third connecting plate 123. A connecting sleeve 126 is fixed to the side of the fourth connecting plate 124 facing away from the third connecting plate 123, and the axis of the connecting sleeve 126 is perpendicular to the third connecting plate 123, and the inner cavity of the connecting sleeve 126 is adapted to the outer peripheral surface of the frame connecting rod 11.

It is ensured that in actual use, when the polygonal frame 1 is placed on the water surface, as long as the polygonal frame 1 is parallel to the horizontal plane as a whole, the guide cylinder 13 is perpendicular to the horizontal plane, thereby ensuring the verticality of the pile foundation.

And the connecting head 12 connected to the first connecting rod 2 is arranged between two connecting heads 12 for connecting the frame connecting rod 11. The specific connection method of the first connecting rod 2 and the guide cylinder 13 is the same as the connection method between the frame connecting rod 11 and the guide cylinder 13, which will not be repeated here. The connecting heads 12 on the guide cylinder 13 are arranged at intervals to avoid interference. The use of the first connecting rod 2 can improve the overall strength of the polygonal frame 1 and improve stability.

[0047] Preferably, in this embodiment, Figure 1 As shown, a second connecting rod 3 is arranged between adjacent first connecting rods 2, and the polygonal shape formed by each second connecting rod 3 is similar to the shape of the polygonal frame 1, that is, each second connecting rod 3 also forms a regular hexagon, and the regular hexagon is arranged as a whole inside the polygonal frame 1. Specifically, in this embodiment, the end of the second connecting rod 3 is arranged at the midpoint of the first connecting rod 2, and the length of the second connecting rod 3 is half of the frame connecting rod 11. The second connecting rod 3 can improve the overall strength of the polygonal frame 1.

[0048] In this embodiment, preferably, two polygonal frames 1 are arranged vertically at intervals, the two polygonal frames 1 are arranged in parallel, and the guide cylinder 13 of the upper polygonal frame 1 is coaxially arranged opposite to the guide cylinder 13 of the lower polygonal frame 1, and the two polygonal frames 1 are fixedly connected by a connecting vertical rod 4.

[0049] Specifically, Figure 1As shown, the end of the connecting vertical rod 4 is used to support and fix on the first connecting rod 2 of the corresponding side polygonal frame 1, and the end of the connecting vertical rod 4 is set at the intersection of the adjacent second connecting rod 3. In this way, the connecting vertical rod 4 can be used to cooperate with the second connecting rod 3 to improve the overall strength of the guide frame and improve the overall stability. Two polygonal frames 1 are arranged at intervals along the vertical direction. On the one hand, the safety and integrity are improved. On the other hand, the upper and lower layers of the opposite guide cylinders 13 can improve the guidance accuracy and ensure the accuracy of the pile foundation.

[0050] Preferably, Figure 1 As shown, in this embodiment, the fixing structure 5 is arranged on the upper polygonal frame 1. Specifically, the fixing structure 5 includes two parallel fixed rods 51, and the two fixed rods 51 are arranged at intervals at the two ends of one of the frame connecting rods 11. One end of the fixing rod 51 is fixedly connected to the guide cylinder 13 at the end of the frame connecting rod 11, and the other end extends outward perpendicular to the frame connecting rod 11 and is used to be fixed on the pile driving ship, and the plane where the two fixing rods 51 are located is arranged parallel to the upper side of the polygonal frame 1. Of course, in other embodiments, the fixing structure 5 can also be arranged on the lower polygonal frame 1.

[0051] Both ends of the fixing rod 51 are provided with connectors 12, and the end of the fixing rod 51 facing the guide cylinder 13 is fixedly connected to the guide cylinder 13 through the connector 12, and the end of the fixing rod 51 facing away from the guide cylinder 13 is fixedly connected to the piling ship through the connector 12. The specific connection method of the connector 12 is the same as above, and will not be repeated here.

[0052] In this embodiment, preferably, the guide frame further includes a buoyancy structure, which is used to support the polygonal frame 1 so that the polygonal frame 1 floats on the water surface, which is convenient for installation and piling. Specifically, the buoyancy structure includes a buoyancy airbag 6 arranged at the lower part of the lower polygonal frame 1. In other embodiments, the buoyancy structure can also be a buoy or other structure, as long as it ensures that the guide frame can float on the water surface.

[0053] In this way, in actual use, after two piles are driven, the overall position of the guide frame is fixed and will no longer drift with the waves. At this time, the pile-driving ship and the guide frame can be separated, and the buoyancy structure can be used to ensure that the guide frame floats on the sea surface for subsequent pile-driving operations, thereby improving practicality. In other embodiments, the buoyancy structure may not be provided, and the guide frame is fixed on the pile-driving ship during the entire operation.

[0054] In this embodiment, if Figure 1 As shown, preferably, the guide frame further comprises a lifting structure, which is disposed as a whole on the upper polygonal frame 1, and comprises a plurality of lifting rings 7 distributed at intervals along the circumferential direction.

Of course, in other embodiments, the hoisting rings 7 may also be set on the frame connecting rods 11 of the polygonal frame 1.

[0057] The working process of the offshore photovoltaic piling device of the utility model is:

[0058] Firstly, according to the relationship between the operating range of the pile-driving ship and the designed azimuth coordinates of the pile foundation, the positioning system on the pile-driving ship is used to accurately locate the position of the pile-driving ship, and the anchor is dropped to tighten and fix the position of the pile-driving ship.

[0059] Afterwards, the guide frame of the present application is placed parallel to a certain position away from the piling ship by a crane, the initial position of the guide frame is preliminarily determined by the positioning system of the piling ship, and the guide frame is preliminarily connected and fixed to the corresponding structure outside the piling ship by a fixing rod 51.

[0060] The guide frame is then accurately adjusted to the desired designed position for piling through the positioning system, and the guide frame is finally fixedly connected to the piling ship.

[0061] The pile foundation is inserted into the inner hole of the guide tube 13 to perform the pile foundation driving operation. When approaching the design elevation, the pile driving speed is slowed down, and the pile body mark is finally used to determine that the design pile top elevation has been reached, that is, the pile foundation construction is completed, and the subsequent pile positions are constructed in sequence. After two piles are driven, the fixed structure 5 on the guide frame can be removed, so that the guide frame is separated from the piling ship, and the constructed pile foundation is used to fix the guide frame for subsequent construction operations.

[0062] Similarly, between different groups, as long as there are two or more common pile positions to complete the pile foundation pressing, the fixed structure 5 does not need to be connected.

[0063] After the construction of each group of pile positions is completed, the guide frame is lifted to the next group of positions and the above steps are repeated to carry out pile foundation operations.

[0064] Embodiment 2: This embodiment provides a different polygonal frame. Different from Embodiment 1, in this embodiment, when meeting actual usage requirements, the first connecting rod may not be provided on the polygonal frame.

[0066] Example 4: This example provides a different second connecting rod. Different from Example 1, in this example, when meeting actual usage requirements, the polygon formed by each second connecting rod may not be adapted to the shape of the polygonal frame. For example, the second connecting rod is parallel to the frame connecting rod on the opposite side, but the opposite ends of adjacent second connecting rods do not intersect, so that each second connecting rod is at a different distance from the center of the polygonal frame.

[0067] Embodiment 5: This embodiment provides a different guide frame. Different from Embodiment 1, in this embodiment, when meeting the actual use requirements, only one polygonal frame may be provided. At this time, the guiding accuracy and stability during pile driving may be improved by improving the fit between the inner cavity of the guide cylinder and the outer periphery of the pile foundation, the verticality of the guide cylinder and the horizontal plane, and the length of the guide cylinder.

[0068] Embodiment 6: This embodiment provides a different polygonal frame. Different from Embodiment 1, in this embodiment, when meeting actual use requirements, connecting vertical rods can be arranged between frame connecting rods, and the ends of the connecting vertical rods are fixedly connected to the frame connecting rods on their corresponding sides.

[0069] Embodiment 7: This embodiment provides a different fixing structure. Different from Embodiment 1, in this embodiment, when meeting the actual use requirements, the fixing structure can be a fixing block, and the two ends of the fixing block are respectively fixed to one of the frame connecting rods and the pile driver.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0072] In the description of the embodiments of the present application, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the invented product is usually placed when used. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0073] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted.
