Description

Technical Field

[0001] This application relates to the field of marine photovoltaic equipment technology, and more specifically, to a marine photovoltaic construction vessel. Background Technology

[0002] Currently, large-scale offshore photovoltaic (PV) projects have been constructed in waters deeper than 2 meters, but construction efficiency remains a challenge. The harsh marine environment in deep waters, coupled with the lack of specialized construction equipment, makes offshore construction difficult, inefficient, and costly. Based on years of research and experimentation, the mainstream offshore PV construction scheme currently utilizes four foundation piles to support the upper PV units. This scheme requires fewer foundation piles, and the PV units can be assembled on land at the dock, significantly reducing offshore construction work and improving the efficiency of offshore PV project construction.

[0003] The existing installation process for offshore photovoltaic (PV) equipment involves hoisting the installation pile positioning frame, foundation piles, and PV units onto a transport vessel at the dock. The transport vessel then transports the equipment to the construction area, where a construction vessel completes the installation. This existing construction method requires a large number of participating vessels and results in high construction costs.

[0004] Therefore, how to reduce the number of construction vessels and lower construction costs is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide an offshore photovoltaic construction vessel to reduce the number of construction vessels and lower construction costs.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] The first aspect of this application provides an offshore photovoltaic construction vessel, comprising:

[0008] hull;

[0009] Offshore cranes are installed on the hull of the vessel;

[0010] A pile driving positioning frame positioning fixture is installed on the hull and has a fixture positioning groove for positioning each anti-sinking plate of the pile driving positioning frame.

[0011] A foundation pile positioning fixture is installed on the hull and has a foundation pile positioning groove for positioning the foundation pile.

[0012] A photovoltaic unit positioning fixture is installed on the hull and has a support leg positioning cylinder for positioning the photovoltaic unit's support legs.

[0013] In one possible implementation, the pile driving positioning frame positioning fixture includes multiple limiting members, each of which forms a positioning groove for the fixture, and each anti-sinking plate of the pile driving positioning frame is configured to be inserted into the corresponding positioning groove of the pile driving positioning frame positioning fixture.

[0014] In one possible implementation, the limiting member is an H-beam, and the H-beams are arranged to form the four sides of the tooling positioning groove, and for each side of the tooling positioning groove, the number of H-beams is at least two.

[0015] In one possible implementation, the area of ​​the flange of the H-beam facing the tooling positioning groove is greater than the area of ​​the flange facing away from the tooling positioning groove.

[0016] In one possible implementation, the foundation pile positioning fixture includes a plurality of positioning fixture units arranged parallel and spaced apart along the width direction of the hull, and the positioning fixture unit includes a plurality of partitions arranged spaced apart along the length direction of the hull, with the foundation pile positioning groove formed between two adjacent partitions.

[0017] In one possible implementation, the positioning fixture unit is multi-layered along the height direction of the hull, with the lowest layer of the partition plate being directly fixed to the hull.

[0018] The partitions of all layers except the bottom layer are fixed to the supporting beams, and the supporting beams of all layers except the bottom layer are supported by the supporting longitudinal beams.

[0019] In one possible implementation, each layer of the support beams includes multiple beams along the width direction of the hull, and both ends of each support beam are supported by the support longitudinal beams.

[0020] In one possible implementation, the photovoltaic unit positioning fixture further includes reinforcing ribs, which are connected to the outer walls of the hull and the support leg positioning cylinder, respectively.

[0021] In one possible implementation, a plurality of reinforcing ribs are evenly distributed on the outer periphery of the support leg positioning cylinder.

[0022] In one possible implementation, there are four pile positioning frames, and along the length of the hull, the four pile positioning frames are symmetrically arranged in pairs on both sides of the foundation pile positioning frame.

[0023] There are four photovoltaic unit positioning fixtures, and along the length of the hull, the four photovoltaic unit positioning fixtures are symmetrically arranged on both sides of the four pile positioning frame positioning fixtures.

[0024] The offshore photovoltaic (PV) construction vessel provided in this application is equipped with an offshore crane, enabling the vessel to load and transport foundation piles, pile positioning frames, and PV units at the dock. Furthermore, the vessel is equipped with positioning fixtures for the pile positioning frames, foundation piles, and PV units, allowing for rapid and reliable securing of these components during transport.

[0025] In actual construction, the offshore photovoltaic (PV) construction vessel can load foundation piles and pile positioning frames onto the hull at the dock, and use foundation pile positioning fixtures and pile positioning frame positioning fixtures to position the foundation piles and pile positioning frames on the hull. Then, the foundation piles and pile positioning frames are transported to the offshore construction site, where an offshore crane lifts the pile positioning frame to the construction position. The offshore crane then lifts the four foundation piles into the sleeves of the pile positioning frame, completing the pile driving work. After completing one set of pile driving, the pile positioning frame is lifted and moved to the next location to complete the pile driving work for that location. When it is time to install the PV units, the offshore PV construction vessel returns to the dock, uses an offshore crane to lift the PV units onto the hull, and secures them using PV unit positioning fixtures. The PV units are then transported to the offshore construction site, where an offshore crane lifts the PV units onto their four support legs, inserting them into the four foundation piles, completing the PV unit installation.

[0026] Compared to traditional installation vessels, the offshore photovoltaic (PV) construction vessel provided in this application can independently lift foundation piles, pile positioning frames, and PV units at the dock, eliminating the need for a dockside crane. Upon arrival at the offshore construction site, this vessel can also replace floating cranes for foundation pile driving operations. The offshore PV construction vessel provided in this application combines the functions of a crane, transport vessel, and construction vessel, reducing the number of construction vessels and lowering construction costs.

[0043] The core of this application is to provide an offshore photovoltaic construction vessel to reduce the number of construction vessels and lower construction costs.

[0044] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the application as described in the claims. Additionally, the complete composition represented in the embodiments below is not limited to what is necessary as the solution to the application described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0045] like Figures 1-3 As shown in the embodiments of this application, the offshore photovoltaic construction vessel disclosed includes a hull 100, an offshore crane 140, a pile driving positioning frame positioning fixture 120, a foundation pile positioning fixture 110, and a photovoltaic unit positioning fixture 130.

[0046] The hull 100 is a powered vessel, enabling the offshore photovoltaic construction vessel to transport materials. The offshore crane 140 is mounted on the hull 100, specifically at the stern, where the stern refers to the rear position of the hull 100 along its course of navigation. The offshore crane 140 is a large lifting device specifically designed for marine engineering and offshore operations, capable of adapting to complex marine environments and diverse operational needs. Installing the offshore crane 140 on the hull 100 allows the offshore photovoltaic construction vessel to participate in the erection, dismantling, installation, and maintenance of offshore photovoltaic equipment; in offshore photovoltaic projects, it can be responsible for foundation piles 300, pile positioning frames 200, and photovoltaic units 400 (such as...). Figure 9 and Figure 10 (As shown) They are responsible for hoisting and loading ships at the dock, as well as hoisting and installation at the construction site.

[0047] The pile driving positioning frame positioning fixture 120 is mounted on the hull 100 and has fixture positioning slots 122 for positioning each anti-sinking plate 210 of the pile driving positioning frame 200. The pile driving positioning frame 200 is a key piece of equipment used in pile driving construction to determine the accurate position of the foundation pile 300 and ensure the accuracy of pile driving.

[0048] A pile driving positioning frame 200 generally includes a connecting frame, an anti-sinking plate 210 mounted on the connecting frame, and a sleeve. The connecting frame is usually made of welded or bolted steel sections and is used to support the sleeve and the anti-sinking plate 210. The shape and size of the connecting frame are customized according to different construction sites and the arrangement of foundation piles 300, and common types include rectangular frames and triangular frames.

[0049] The sleeve is typically made of high-strength metal and has a cylindrical structure. Its inner diameter is slightly larger than the outer diameter of the foundation pile 300, with a general gap of about 2-5 centimeters, depending on the type of foundation pile 300 and construction requirements. The function of the sleeve is to provide precise guidance for the foundation pile 300. During the pile driving process, the foundation pile 300 sinks along the inner wall of the sleeve, effectively limiting the horizontal deviation of the foundation pile 300 and ensuring that the foundation pile 300 reaches the predetermined position vertically and accurately.

[0050] The anti-sinking plate 210 is generally a square metal plate, the thickness of which is determined according to the actual engineering requirements. Installed at the bottom of the connecting frame, the anti-sinking plate 210 has a large area, increasing the contact area between the pile driving positioning frame 200 and the seabed. The main function of the anti-sinking plate 210 is to prevent the pile driving positioning frame 200 from sinking due to the impact force of the foundation pile 300 during pile driving, maintaining the stability of the pile driving positioning frame 200. For example, when performing pile driving operations in soft muddy areas of the seabed, the anti-sinking plate 210 can disperse the pressure of the pile driving positioning frame 200 on the ground, preventing the pile driving positioning frame 200 from sinking too deeply, thereby ensuring the accuracy of positioning.

[0051] Since the anti-sinking plate 210 is located at the bottom of the pile positioning frame 200, a tooling positioning groove 122 is set on the pile positioning frame positioning tooling 120, and the anti-sinking plate 210 of the pile positioning frame 200 is inserted into the tooling positioning groove 122, so that the pile positioning frame 200 can be kept stable and reliable on the hull 100.

[0052] The foundation pile positioning fixture 110 is mounted on the hull 100 and has a foundation pile positioning groove for positioning the foundation piles 300. The foundation piles 300 are structural components in offshore photovoltaic power generation systems used to support photovoltaic modules and related equipment, and to fix them to the seabed or ocean floor. Their performance and quality directly affect the stability and safety of the entire offshore photovoltaic project. The cross-section of the foundation piles 300 is typically circular; therefore, when transporting the foundation piles 300 on an offshore photovoltaic construction vessel, they should be transported on their back and confined within the foundation pile positioning groove of the foundation pile positioning fixture 110 to restrict the rolling of the foundation piles 300.

[0053] The photovoltaic unit positioning fixture 130 is mounted on the hull 100 and has a support leg positioning cylinder 131 for positioning the support legs 410 of the photovoltaic unit 400, such as... Figure 8 As shown, the support leg positioning cylinder 131 simulates the structure of the foundation pile 300, so that the support leg 410 of the photovoltaic unit 400 can be inserted into the support leg positioning cylinder 131 to ensure the fixation of the photovoltaic unit 400 on the hull 100.

[0054] The offshore photovoltaic construction vessel disclosed in this application is equipped with an offshore crane 140 on its hull 100, enabling the vessel to load and transport foundation piles 300, pile positioning frames 200, and photovoltaic units 400 at the dock. Furthermore, the hull 100 is also equipped with pile positioning frame positioning fixtures 120, foundation pile positioning fixtures 110, and photovoltaic unit positioning fixtures 130, allowing the vessel to quickly and reliably secure the foundation piles 300, pile positioning frames 200, and photovoltaic units 400 during transportation.

[0055] In actual construction, the offshore photovoltaic construction vessel can load the foundation piles 300 and pile driving positioning frames 200 onto the hull 100 at the dock, and use the foundation pile positioning fixture 110 and pile driving positioning frame positioning fixture 120 to position the foundation piles 300 and pile driving positioning frames 200 on the hull 100 respectively. Then, the foundation piles 300 and pile driving positioning frames 200 are transported to the offshore construction site. An offshore crane 140 is used to hoist the pile driving positioning frame 200 to the construction position, and then the offshore crane 140 hoists four foundation piles 300 into the sleeves of the pile driving positioning frame 200, completing the pile driving work. After completing one set of pile driving work, the pile driving positioning frame 200 is lifted and transferred to the next machine position to complete the pile driving work at the next machine position. A single transport can complete pile driving work at several machine positions, depending on the number of foundation piles 300 that can be transported in one trip. Taking the transportation of 40 foundation piles (300mm) as an example, one transportation can complete the pile driving work for 10 machine positions.

[0056] When the photovoltaic unit 400 needs to be installed, the offshore photovoltaic construction vessel returns to the dock, and the offshore crane 140 lifts the photovoltaic unit 400 onto the hull 100, and fixes it with the photovoltaic unit positioning fixture 130. Then the photovoltaic unit 400 is transported to the offshore construction site, and the offshore crane 140 lifts the photovoltaic unit 400 into its four support legs, which are then inserted into the four foundation piles 300, completing the installation of the photovoltaic unit 400.

[0057] Compared to traditional installation vessels, the offshore photovoltaic construction vessel disclosed in this application can independently lift and install foundation piles 300, pile positioning frames 200, and photovoltaic units 400 at the dock, eliminating the need for a dockside crane. Upon arrival at the offshore construction site, this offshore photovoltaic construction vessel can also replace floating cranes for the pile driving operation of the foundation piles 300. The offshore photovoltaic construction vessel provided in this application simultaneously possesses the functions of multiple vessels, including a crane, a transport vessel, and a construction vessel, reducing the number of construction vessels and lowering construction costs.

[0058] like Figure 1 , Figure 6 and Figure 7As shown in a specific embodiment of this application, the pile positioning frame positioning fixture 120 includes multiple limiting members 121, each limiting member 121 forming a fixture positioning groove 122. The number of limiting members 121 is not limited, as long as they can form the fixture positioning groove 122 surrounding the anti-sinking plate 210. The limiting members 121 can be directly welded to the deck of the hull, or welded to a support plate, and the support plate can be fixed to the deck by bolts or welding. This embodiment does not limit the method of fixing the limiting members 121 to the hull 100. The height of the limiting members 121 (i.e., the depth of the fixture positioning groove 122) is not limited, as long as it ensures that the pile positioning frame 200 will not collapse during transportation after the anti-sinking plate 210 is inserted into the fixture positioning groove 122.

[0059] It should be noted that the number of the pile positioning frame positioning fixture 120 packages should correspond one-to-one with the number of the anti-sinking plates 210 of the pile positioning frame 200, so as to ensure that each anti-sinking plate 210 of the pile positioning frame 200 can be inserted into the corresponding tooling positioning groove 122 of the pile positioning frame positioning fixture 120.

[0060] Furthermore, the limiting component 121 is an H-beam, which has sufficient supporting strength and is relatively inexpensive. The H-beams are arranged to form the four sides of the tooling positioning groove 122 (the anti-sinking plate 210 is a rectangular structure), and for each side of the tooling positioning groove 122, there are at least two H-beams. Setting more than two H-beams for each side of the anti-sinking plate 210 improves the reliability of limiting the anti-sinking plate 210 and makes it easier to resist the swaying of the anti-sinking plate 210 within the tooling positioning groove 122. The H-beams corresponding to each side of the anti-sinking plate 210 can be arranged at intervals, and the interval distance and number of H-beams corresponding to each side can be equal. Of course, those skilled in the art can further design according to requirements, choosing the number and spacing of H-beams corresponding to each side, or designing the number and spacing of H-beams corresponding to each side to be unequal.

[0061] As will be understood by those skilled in the art, an H-beam typically includes two parallel flanges and a web connecting the two flanges, with the web usually positioned between the two flanges. One of the flanges of the H-beam is used to form the edge of the tooling positioning groove 122.

[0062] In this embodiment, to improve the limiting effect, the area of ​​the wing plate of the H-beam facing the tooling positioning groove 122 is larger than the area of ​​the wing plate facing away from the tooling positioning groove 122. That is, in this embodiment, the two wing plates of the H-beam have different areas, with the wing plate facing the tooling positioning groove 122 having a larger area. This ensures that when the pile driving positioning frame 200 shakes, it can generate a larger contact area with the anti-sinking plate 210, thereby improving the reliability of the limiting effect.

[0063] like Figure 4and Figure 5 As shown in a specific embodiment of this application, the foundation pile positioning fixture 110 includes a plurality of positioning fixture units arranged parallel and at intervals along the width direction of the hull 100. Each positioning fixture unit includes a plurality of partitions 113 arranged at intervals along the length direction of the hull 100, with a foundation pile positioning groove formed between adjacent partitions 113.

[0064] The width of the foundation pile positioning groove (i.e., the distance between the partitions 113) should be slightly larger than the diameter of the foundation pile 300 so that the foundation pile 300 can be embedded in the foundation pile positioning groove and reduce rolling within the foundation pile positioning groove.

[0065] The foundation pile 300 is positioned at different locations along its axial direction on different positioning fixture units, so that there are multiple fixing points along the axial direction of the foundation pile 300, ensuring the foundation pile 300 is reliably fixed and preventing the foundation pile 300 from moving.

[0066] Among the multiple positioning fixture units arranged parallel and spaced apart along the width direction of the hull 100, the spacing between any two adjacent positioning fixture units can be designed to be the same, or the spacing and position of each positioning fixture unit can be designed according to the structural characteristics of the foundation pile 300 and the position that the foundation pile 300 needs to be fixed.

[0067] To improve loading efficiency, multiple layers of positioning tooling units can be arranged along the height of the hull 100. The lowest layer bulkhead 113 is directly fixed to the hull 100, for example, it can be directly fixed to the deck 150. Specifically, the lowest layer bulkhead 113 can be directly welded to the deck 150 or welded to a support plate, and the support plate is fixed to the deck 150 by bolts or welding.

[0068] The partitions 113 of all layers except the bottom layer are fixed to the supporting beams 111, and the supporting beams 111 of all layers except the bottom layer are supported by the supporting longitudinal beams 112. That is, the supporting longitudinal beams 112 raise the supporting beams 111 to a certain height, which must meet the requirement of not affecting the positioning of the foundation piles 300 by the positioning fixture unit of the lower layer.

[0069] When the foundation pile 300 is loaded onto the ship, it can be inserted into the foundation pile positioning groove of each positioning tooling unit from one end of the width direction of the hull 100; when the foundation pile 300 is unloaded, it is pulled out from the foundation pile positioning groove of each positioning tooling unit along the axial direction of the foundation pile 300 in the same way.

[0070] To improve the loading and unloading efficiency of the foundation piles 300, the positioning fixtures of all layers except the bottom layer are designed with a detachable fixing method. That is, when loading the foundation piles 300 onto the ship, the upper positioning fixtures are not installed initially, allowing the foundation piles 300 to be directly lowered into the foundation pile positioning slots of each positioning fixture unit from the upper side of the hull 100. After the bottom layer positioning fixture unit has completed loading the foundation piles 300, its upper positioning fixture unit (for ease of understanding, this layer is defined as the second layer positioning fixture unit) is fixed to the deck 150. Then, the foundation piles 300 on the second layer positioning fixture unit are loaded, and so on, until the foundation piles 300 on the other layers of positioning fixture units are loaded. It should be noted that the positioning fixtures of other layers can be fixed to the deck 150 or to the supporting longitudinal beams 112 of the positioning fixture unit below it.

[0071] When unloading foundation pile 300, the foundation pile 300 on the topmost positioning fixture unit can be unloaded first. After the foundation pile 300 on the topmost positioning fixture unit is unloaded, the topmost positioning fixture unit is disassembled, and then the foundation pile 300 on the next layer of positioning fixture unit is unloaded. The unloading of foundation pile 300 on all layers of positioning fixture units is completed in sequence.

[0072] Because the foundation piles 300 have a large mass, in order to prevent the supporting beams 111 supporting the foundation piles 300 from deforming due to the weight of the foundation piles 300, in this embodiment, each layer of supporting beams 111 includes multiple beams along the width direction of the hull 100. This can be understood as splitting the original single supporting beam 111 of the positioning fixture unit into multiple beams to prevent deformation due to the long length of the supporting beams 111.

[0073] Each supporting crossbeam 111 is supported at both ends by supporting longitudinal beams 112. It should be noted that, in addition to supporting the supporting crossbeam 111 and elevating it, the supporting longitudinal beam 112 also functions as a partition 113. That is, at the location where the supporting longitudinal beam 112 is set, one side of the foundation pile 300 is secured by the partition 113, and the other side is limited by the supporting longitudinal beam 112; in other words, at the location where the supporting longitudinal beam 112 is set, one of the two side walls of the foundation pile positioning groove serves as the supporting longitudinal beam 112, and the other as the partition 113.

[0074] Both the longitudinal support beam 112 and the transverse support beam 111 can be H-beams, or other profiles. This embodiment does not limit the specific structure and material of the longitudinal support beam 112 and the transverse support beam 111.

[0075] like Figure 8As shown in a specific embodiment of this application, the photovoltaic unit positioning fixture 130 may further include reinforcing ribs 132, which are connected to the outer walls of the hull 100 and the support leg positioning cylinder 131, respectively. In this embodiment, the reinforcing ribs 132 are welded to the outer wall of the support leg positioning cylinder 131, and the reinforcing ribs 132 are also welded to the hull 100 (specifically, they can be welded to the deck of the hull 100), which can improve the reliability of the support leg positioning cylinder 131 being fixed on the hull 100.

[0076] The photovoltaic unit 400 has a large mass and volume, and a high center of gravity. During transportation of the photovoltaic unit 400, when the photovoltaic construction vessel is swayed by waves at sea, the force exerted by the photovoltaic unit 400 on the support leg positioning cylinder 131 is relatively large. In this embodiment, by adding reinforcing ribs 132, the connection strength of the support leg positioning cylinder 131 can be improved to resist the swaying of the photovoltaic unit 400.

[0077] Furthermore, multiple reinforcing ribs 132 are evenly arranged on the outer periphery of the support leg positioning cylinder 131. Figure 8 In the illustrated design, there are four reinforcing ribs 132, which are evenly arranged along the circumference of the support leg positioning cylinder 131. The reinforcing ribs 132 can also be profiles, such as H-beams, to achieve greater support reliability.

[0078] like Figure 3 As shown, in this embodiment, there are four pile positioning frame positioning fixtures 120, and along the length of the hull 100, the four pile positioning frame positioning fixtures 120 are symmetrically arranged in pairs on both sides of the foundation pile positioning fixture 110. That is, along the length of the hull 100, two pile positioning frame positioning fixtures 120 are arranged on one side of the foundation pile positioning fixture 110, and two pile positioning frame positioning fixtures 120 are symmetrically arranged on the other side. The arrangement of the four pile positioning frame positioning fixtures 120 is the same as the arrangement of the anti-sinking plates 210 of the pile positioning frame 200. Therefore, once the pile positioning frame 200 is determined, the spacing of the four pile positioning frame positioning fixtures 120 is also determined. Based on the spacing of the four pile positioning frame positioning fixtures 120 along the length of the hull 100, the length of each fixture can be designed to determine how many foundation piles 300 can be placed along the length of the hull 100. That is, the foundation piles 300 can only be arranged outside the pile positioning frame positioning fixtures 120. Since the foundation piles 300 occupy little space in the height direction of the hull 100, the foundation piles 300 and the pile positioning frame 200 can be transported simultaneously (e.g., ...). Figure 1 (As shown).

[0079] There are four photovoltaic unit positioning fixtures 130 (depending on the number of support legs 410 of the photovoltaic unit 400), and along the length of the hull 100, the four photovoltaic unit positioning fixtures 130 are symmetrically arranged in pairs on both sides of the four pile positioning frame positioning fixtures 120. Since the photovoltaic unit 400 is larger, the photovoltaic unit positioning fixtures 130 are arranged further out.
