Description

Technical Field

[0001] The present invention relates to the technical field of offshore photovoltaic construction, and in particular to an offshore photovoltaic bracket loading and unloading ship stacking tool and a lightering operation method thereof. Background Art

[0002] my country's offshore photovoltaic industry chain is developing rapidly and has begun to take shape, making it a crucial source of clean energy for the future. Offshore photovoltaics refer to photovoltaic power stations installed on the sea surface, typically employing either floating or pile-based structures. Pile-based offshore photovoltaics, in which photovoltaic mounts are anchored in the sea via piles, offer the following advantages: 1) they offer high power generation efficiency due to the vast sea surface, minimal obstruction, and low power generation efficiency; 2) they do not require land resources, making them suitable for use in areas with limited land resources; and 3) they can be integrated with fisheries, aquaculture, and other industries, enabling multi-purpose utilization.

[0003] At present, offshore photovoltaic brackets are assembled into trusses or grid structures with lower chords, upper chords, diagonal braces and other rods, and then the construction is completed by installing photovoltaic panels on the brackets. Due to the short construction window at sea and the difficulty of operation, the brackets are currently mostly assembled on land, transported to the construction site by barge, and installed on site by crane ships. However, due to the large number of bracket rods, overall size and weight, stacking is more difficult, and a single barge is often used to transport a single set of brackets. Therefore, when the transportation distance is long, the cost of ship and machinery is extremely high, resulting in a large waste of resources. Based on this, it is necessary to design a tooling structure that can improve the efficiency of barge transportation in order to optimize resource utilization and reduce barge transportation costs in response to the above technical problems.

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the following embodiments are by no means intended to limit the present invention in any way.

[0038] See also Figures 1 to 13 This offshore photovoltaic rack loading and unloading and stacking tooling is suitable for batch transport of offshore photovoltaic racks 2 using a barge 5. The offshore photovoltaic racks 2 are large-scale structural racks that are pre-assembled on land and then transported to a designated offshore construction location via the barge 5. In this embodiment, the offshore photovoltaic rack 2 includes a photovoltaic assembly, a support truss, and connecting legs arranged sequentially from top to bottom. The photovoltaic assembly is composed of several photovoltaic panels, which are laid flat on the top surface of the support truss via the connecting assembly. Four connecting legs are provided, evenly distributed and fixed to the bottom surface of the support truss for connection to the offshore pile foundation.

[0039] The offshore photovoltaic bracket loading and unloading ship stacking tooling specifically includes a barge widening and reinforcement tooling, a photovoltaic bracket installation tooling 3 and a stacking tooling; wherein, the barge widening and reinforcement tooling is used to realize the dimensional extension of the barge in its width direction to adapt to the width of the offshore photovoltaic bracket 2; the photovoltaic bracket installation tooling 3 is used to connect and fix with the offshore photovoltaic bracket 2; the stacking tooling is arranged between two adjacent offshore photovoltaic brackets 2 in a stacked arrangement, and while realizing the fixation of the offshore photovoltaic bracket 2, a safe setting distance is separated between the two adjacent offshore photovoltaic brackets 2 to avoid damage to the offshore photovoltaic bracket 2 due to collision during transportation.

[0040] See also Figure 1 and Figure 6 According to the number of four connecting legs at the bottom of the offshore photovoltaic bracket 2, the barge widening and reinforcement tooling is correspondingly composed of four groups of extension mechanisms. Two groups of extension mechanisms are symmetrically arranged on the left and right outer walls of the ship's hull on the front side of the barge 5, and the other two groups of extension mechanisms are symmetrically arranged on the left and right outer walls of the ship's hull on the rear side of the barge 5, so that the positions of the four groups of extension mechanisms correspond to the positions of the connecting legs at the bottom of the offshore photovoltaic bracket 2.

[0041] Each extension mechanism consists of two extension components 1 arranged at intervals. Each extension component 1 includes a horizontally arranged outrigger support plate 1-1, below which five reinforcing ribs 1-2 are arranged vertically and evenly spaced. The five reinforcing ribs 1-2 are arranged in parallel and at intervals, and the ends on the same side as the outrigger support plate 1-1 are welded and fixed to the outer wall of the ship to achieve a fixed connection with the barge 5; the five reinforcing ribs 1-2 are welded and fixed to the bottom surface of the outrigger support plate 1-1.

[0042] In this embodiment, the outrigger support plate 1-1 is made of rectangular steel plate, and the reinforcing rib 1-2 is made of trapezoidal steel plate, and is arranged with the oblique side facing upward so that its two right-angled sides are welded and fixed to the outer wall of the ship's side and the outrigger support plate 1-1, thereby increasing the connection surface area while controlling the weight and improving the connection strength between the extension component 1 and the outer wall of the ship's side.

[0043] See also Figure 6 As shown in Figure 7, the photovoltaic bracket installation tooling 3 consists of four sets of guide assemblies and four legs 3-2; wherein, the four sets of guide assemblies are respectively arranged at the four groups of extension mechanisms in a one-to-one correspondence; specifically, each set of guide assemblies is composed of four guide tubes 3-1, wherein two guide tubes 3-1 are respectively fixed in the center on the top surface of the extended support plate 1-1 of the two extension assemblies 1, and the other two guide tubes 3-1 are fixed on the deck of the barge 5, and are arranged symmetrically with the above-mentioned two guide tubes 3-1, so that the four guide tubes 3-1 are arranged at intervals along the circumferential direction and can be connected in sequence to form a rectangle; the four legs 3-2 correspond one-to-one to the four groups of guide assemblies, and are fixed on the deck corresponding to the center position of the four guide tubes 3-1 in each group of guide assemblies.

[0044] The guide tube 3-1 is arranged vertically and its bottom end is welded and fixed to the deck or the extended support plate 1-1; the lower part of the tube body is a cylindrical cylinder, and its upper part is a tapered cylinder with an outer diameter gradually decreasing from top to bottom, so that the guide tube 3-1 forms a "trumpet"-shaped open end with a plug-in guide structure; two groups of first radial jacks are symmetrically opened on the side wall of the lower part of the tube body, and the two groups of first radial jacks are respectively opened at different height positions of the cylindrical cylinder and are vertically distributed.

[0045] The leg 3-2 includes a vertically arranged support tube 3-3, the bottom end of which is welded and fixed to the deck, and the top end surface of which is processed into a plane or inclined surface adapted to the flange plate 2-2 on the offshore photovoltaic bracket 2 connecting the leg; specifically, see Figure 8The connecting leg at the bottom of the offshore photovoltaic bracket 2 is composed of a connecting part, a flange plate 2-2 and a plug tip 2-1 from top to bottom; according to different offshore photovoltaic construction locations, photovoltaic modules are set horizontally or obliquely at sea to adapt to the light conditions at sea, so the flange plate 2-2 of the connecting leg is correspondingly set horizontally or obliquely; a leg flange plate 3-4 is welded and fixed to the top of the support tube 3-3, and an annular groove surrounding the center hole is opened on the top surface of the leg flange plate 3-4, and the inner diameter of the annular groove is adapted to the outer diameter of the flange plate 2-2 on the connecting leg, so that the connecting leg is set on the support tube 3-3 with its plug tip 2-1 inserted in the support tube 3-3 and the flange plate 2-2 embedded in the annular groove. On the leg 3-2; two arc-shaped fixing plates 3-5 are symmetrically arranged on the leg flange plate 3-4, the curvature of the two is adapted to the curvature of the leg flange plate 3-4, and the spacing is smaller than the inner diameter of the annular groove; two screw holes corresponding to the openings on the leg flange plate 3-4 are provided on the plate surface of each arc-shaped fixing plate 3-5, so that the two are fixed to the leg flange plate 3-4 by bolts 3-6 and matching nuts successively passed through the arc-shaped fixing plate 3-5 and the leg flange plate 3-4; because the spacing between the two arc-shaped fixing plates 3-5 is smaller than the inner diameter of the annular groove, the two are simultaneously press-fitted on the flange plate 2-2, so that the connecting leg of the offshore photovoltaic bracket 2 is fixedly connected to the leg 3-2, see Figure 9 .

[0046] In this embodiment, the guide tube 3-1 and the support legs 3-2 are both made of steel to ensure structural strength and facilitate welding connection.

[0047] See also Figures 1 to 5 The stacking tooling is composed of multiple sets of stacking components. Based on this embodiment, the number of offshore photovoltaic brackets 2 transported by the barge 5 in batches is three, and the corresponding number of stacking components is three. Figure 1 Each set of stacking components consists of four stacking brackets 4, which are respectively arranged at four groups of extension mechanisms.

[0048] See also Figure 13 The stacked bracket 4 includes four vertically arranged bracket tubes 4-2, the top sides of which are fixed at the four top corners of the horizontally arranged bracket platform 4-7; the distance between the four bracket tubes 4-2 is adapted to the distance between the four guide tubes 3-1 in the photovoltaic bracket installation tool 3, so that the bottom ends of the four bracket tubes can be inserted into the four guide tubes 3-1; see Figure 12Two vertically distributed guide tubes 4-3 are symmetrically provided on the sidewalls of the bottom end of each support tube 4-2. These guide tubes 4-3 respectively cooperate with the two sets of first radial holes provided on the guide tube 3-1, so that when the support tube 4-2 is inserted into the guide tube 3-1, the two sets of first radial holes respectively intersect with the two guide tubes 3-1. The support tube 4-2 is fixedly connected to the guide tube 3-1 by bolts and matching nuts respectively provided through each set of first radial holes and the guide tube 4-3. In addition, since the spacing between the four support tubes 4-2 is adapted to the spacing between the four guide tubes 3-1 in the photovoltaic support installation tool 3, the above-mentioned connection method can also be used to achieve fixation between the stacked supports 4 in the subsequent stacking operation. A support guide tube 4-11 is provided at the top of each support tube 4-2. The structure of the support guide tube 4-11 is the same as that of the guide tube 3-1 in the photovoltaic support installation tool 3, and its bottom end is welded and fixed to the top end face of the support tube 4-2.

[0049] As a preferred technical solution of this embodiment, an external connecting truss 4-5 is connected between every two adjacent support tubes 4-2 located above the support platform 4-7, and a guardrail 4-6 is fixed between the adjacent truss beams of each external connecting truss 4-5; two internal connecting trusses 4-8 are fixed centrally between two external connecting trusses 4-5 located on opposite sides of one group, and a support leg 4-9 is fixed centrally inside the two internal connecting trusses 4-8. The structure of the support leg 4-9 is the same as that of the support leg 3-2 in the photovoltaic support installation tooling 3, which is specifically fixed between the two internal connecting trusses 4-8 by welding a steel plate 4-10 vertically arranged and fixed on the outer wall on the opposite side.

[0050] As a preferred technical solution of this embodiment, a support ladder 4-4 is provided on the side wall of one of the support tubes 4-2, and a manhole is opened on the support platform 4-7 adjacent to the support ladder 4-4.

[0051] In this embodiment, all components constituting the stacking bracket 4 are made of steel components to facilitate their own welding, fixing and assembly.

[0052] See also Figure 3 、 Figure 4 and Figure 10For each set of stacking components, the four stacking brackets 4 it contains have a structural connection function that connects the upper and lower parts, that is, the bottom side of each stacking bracket 4 is used to be connected to the connection structure (such as the deck) of the offshore photovoltaic bracket 2 below, and the top side is used to be connected to the connecting legs at the bottom of the upper offshore photovoltaic bracket 2, and the height setting is used to realize that the upper and lower offshore photovoltaic brackets 2 are fixed on the barge in an interval-set manner; based on this, in order to facilitate the setting of the stacking brackets, in actual applications, when the offshore photovoltaic bracket 2 is assembled on land, the multiple photovoltaic panels located above the connecting legs are not installed temporarily, so as to reserve four H-shaped installation gaps on the support truss for inserting and setting the stacking brackets 4; accordingly, in order to ensure the smooth insertion and setting of the stacking bracket 4, the outer diameter of the bracket tube 4-2 is smaller than the spacing between adjacent rods on the support truss, so as to ensure that the bracket tube 4-2 can pass through the support truss of the offshore photovoltaic bracket 2. Subsequently, after each offshore photovoltaic bracket 2 is installed and fixed on the top of the offshore steel pipe pile, multiple photovoltaic panels that have not been installed are installed on the offshore photovoltaic bracket 2 through connecting components to make the structure of the offshore photovoltaic bracket 2 complete.
