Description

Technical Field

[0001] The present invention belongs to the technical field of offshore photovoltaic, and particularly relates to a lock structure for recyclable offshore photovoltaic panels. Background Art

[0002] At present, offshore photovoltaic has entered a new cycle of rapid development. At the present stage, marine photovoltaic is mainly based on pile foundation fixation. The structural form is that photovoltaic panels are installed on a supporting steel platform, the supporting steel platform is seated on pile foundations, and the pile foundations are embedded in the seabed rock formation to form a complete offshore photovoltaic unit platform.

[0003] During construction, due to the complex offshore operation environment, including strong winds and waves, typhoons, sea ice, high humidity, and frequent temperature changes, it means that offshore photovoltaic work is more stringent than ground photovoltaic, and the operation difficulty is also greater. Usually, the assembly of photovoltaic panels except at the lifting ports is completed on land. The photovoltaic panels are installed on the purlins of the steel platform in a fixed manner. Finally, a marine crane lifts the photovoltaic platform to the offshore pile foundation. After the lifting is completed, the missing photovoltaic panels at each lifting port position are supplemented and installed, thus completing the last piece of the puzzle for the installation of the photovoltaic unit platform.

[0004] The traditional method for supplementing and installing photovoltaic panels at the lifting ports relies on marine cranes. The main activity in offshore operations is lifting operations. The lifting operation of marine cranes is a key process for controlling the project schedule nodes. Lifting photovoltaic panels one by one will greatly restrict the on-site construction progress. In addition, facing the harsh offshore weather and high-altitude operations, there is also a risk of high-altitude falling of photovoltaic panels in traditional lifting operations, and there are many steel structure members below the photovoltaic modules, making the construction difficult.

[0005] Therefore, in order to solve the problem that the installation operation of supplementing panels at the lifting ports occupies the marine crane and thus affects the overall construction progress, and at the same time to shorten the offshore operation time, a method for installing offshore photovoltaic panels and a lock structure for recyclable offshore photovoltaic panels are provided. Summary of the Invention

[0006] The purpose of the present invention is to provide a method for installing offshore photovoltaic panels and a lock structure for recyclable offshore photovoltaic panels. The aim is to reduce the dependence on marine cranes for the supplementary installation of photovoltaic panels at the lifting ports during offshore operations. By temporarily fixing the photovoltaic panels to be installed on the existing photovoltaic platform and hoisting them to the pile foundation together with the platform main body, after the main body hoisting is completed, the temporary fixing device is removed to complete the supplementary installation of the photovoltaic panels at the lifting ports.

[0007] On the one hand, the present invention is achieved by the following measures: A method for installing offshore photovoltaic panels, characterized in that the photovoltaic panels missing at the lifting ports are detachably fixedly connected to adjacent photovoltaic panels and hoisted together with the entire photovoltaic platform.

[0008] Further, the missing photovoltaic panel at the hoisting opening is fixed on the adjacent photovoltaic panel above the hoisting opening. Since there is a 15° angle between the offshore photovoltaic panel and the horizontal plane, it is convenient to move the missing photovoltaic panel at the hoisting opening to the hoisting opening in the later stage.

[0009] Further, the missing photovoltaic panel at the hoisting opening is arranged on the adjacent photovoltaic panel through a plurality of locking structures;

[0010] The locking structure includes a U-shaped limiting member inserted into the purlin of the steel platform and a connecting member sleeved on the open end of the U-shaped limiting member;

[0011] One side of the U-shaped limiting member is fixedly provided with a sleeve, a screw rod is arranged through the sleeve, the upper end of the screw rod extends out of the sleeve and is provided with an upper locking block, and the lower end of the screw rod extends out of the sleeve and is provided with a locking nut through threaded connection;

[0012] The connecting member is fixedly arranged on the U-shaped limiting member in a detachable manner.

[0013] Further, it also includes a U-shaped clamping member fixed above the purlin, and the U-shaped limiting member is clamped into the U-shaped clamping member. The upper ends of both sides of the U-shaped clamping member are provided with out-turned plates, and the upper-layer photovoltaic panel can be lapped on the out-turned plates.

[0014] Further, the U-shaped clamping member is welded on the purlin or fixed on the purlin through screws.

[0015] Further, the U-shaped limiting member includes an upper side plate located above the purlin, a lower side plate located below the purlin and a vertical plate located on one side of the purlin. The upper side plate is clamped in the clamping groove of the U-shaped clamping member, and the sleeve is fixed on the outer side of the vertical plate.

[0016] Further, the connecting member is provided with a connection port matching the U-shaped limiting member, the lower end of the connection port is open, and the open end is connected with the lower side plate in a detachable manner.

[0017] Further, a baffle is fixedly arranged above the upper side plate and on the outer side of the connecting member.

[0018] Further, a lower locking block is arranged at intervals below the upper locking block on the screw rod, and the upper locking block is rotatably arranged on the screw rod, generally through bearing rotation connection.

[0019] Among them, the installation method of the offshore photovoltaic panel applying the locking structure includes:

[0020] The onshore operation part, that is, onshore, the photovoltaic panels except those at the hoisting opening and the photovoltaic panels at the hoisting opening are superposed and installed at the upper part of the photovoltaic panel at the hoisting opening. Specifically:

[0021] Step 1: First, fix the U-shaped fasteners on the purlins;

[0022] Step 2: Insert the open end of the U-shaped limit piece from one side of the purlin and make the upper side plate snap into the card slot on the U-shaped fastener.

[0023] Step 3: Insert the connecting piece from the open end of the U-shaped limit piece and fix it with bolts or pin shafts, so that the inner wall of the connecting piece and the inner wall of the U-shaped limit piece are in close contact with the outer wall of the purlin.

[0024] Step 4: Insert the screw into the sleeve so that the lower locking block contacts the upper end face of the lower-layer photovoltaic panel;

[0025] Step 5: Lay a soft isolation medium on the lower-layer photovoltaic panel, and place the upper-layer photovoltaic panel on the soft isolation medium and below the upper locking block.

[0026] Step 6: Pull the screw from below so that the upper locking block presses the upper-layer photovoltaic panel, the lower locking block presses the lower-layer photovoltaic panel, and then tighten the locking nut to fix.

[0027] Step 7: Install ropes in the mounting holes on the outer frame of the photovoltaic panel. The connection points of the ropes and the frame are distributed in an isosceles triangle. The traction end of the rope is fixedly connected to the steel structure at the lifting point. The rope is preferably located below the photovoltaic panel. This can reduce the damage to the photovoltaic panel during the traction process.

[0028] Offshore operation part:

[0029] Step 1: After the photovoltaic platform is hoisted and the lifting point device is released, rotate the upper locking block to disengage the upper locking block from the upper-layer photovoltaic panel and release the temporary locking structure;

[0030] Step 2: Slowly lower the photovoltaic panel by using the ropes and the self-weight of the photovoltaic panel. After it is lowered to the installation position, fix the end of the rope on the truss, and the photovoltaic panels to be supplemented are in place.

[0031] Step 3: Loosen all the nuts and sequentially recover each component of the locking structure from the gap between the photovoltaic panels.

[0032] On the other hand, this embodiment provides a recyclable offshore photovoltaic panel locking structure, which is characterized in that it includes a U-shaped limit piece inserted on the purlin of the steel platform and a connecting piece sleeved on the open end of the U-shaped limit piece;

[0033] One side of the U-shaped limit piece is fixedly provided with a sleeve, a screw is penetrated through the sleeve, the upper end of the screw extends out of the sleeve and is provided with an upper locking block, and the lower end of the screw extends out of the sleeve and is provided with a locking nut through threaded connection;

[0034] The connecting piece is fixedly connected to the U-shaped limit piece in a detachable manner.

[0035] Furthermore, it also includes a U-shaped clamp fixed above the purlin, and the U-shaped limiting piece is clamped into the U-shaped clamp.

[0036] Furthermore, the U-shaped clamp is welded to the purlin, or fixed to the purlin by bolts, the upper end of the bolt is fixed to the U-shaped clamp, and the lower end of the bolt passes through the purlin and is fixed by a nut.

[0037] Furthermore, the U-shaped limiting member includes an upper side plate located above the purlin, a lower side plate located below the purlin and a vertical plate located on one side of the purlin, and the U-shaped clamp is arranged on the upper side plate.

[0038] Furthermore, the connecting member is provided with a connecting port matching the U-shaped limiting member, the lower end of the connecting port is open and the open end is connected to the lower side plate in a detachable manner.

[0039] Furthermore, a baffle is fixedly provided above the upper side plate and outside the connecting member.

[0040] Furthermore, a lower locking block is disposed on the screw rod and below the upper locking block. The upper locking block is rotatably disposed on the screw rod.

[0041] The technical solution provided by the embodiment of the present invention has the following beneficial effects: on land, the photovoltaic panels at the lifting port are stacked on the photovoltaic panels that have been installed above the lifting port. After the lifting is completed, the photovoltaic panels at the lifting port can be quickly installed. The photovoltaic panels are temporarily fixed to the installed photovoltaic panels through the locking structure. The locking structure has a simple opening and closing device, and the temporary fixation can be quickly installed and removed. The locking structure can be recovered through the gap between the photovoltaic panels and can be recycled. The existing installation holes of the photovoltaic panels are used to fix the ropes, and the rope device ensures that the photovoltaic panel is lowered smoothly. The offshore lifting operations are greatly reduced, and the reserved panels can be quickly installed and removed, which improves work efficiency. The operation is close to the existing photovoltaic platform, which is safe and reliable, and reduces the risk of photovoltaic panels falling from high places in severe weather and high-altitude operations at sea. A soft isolation medium is set between the panels to protect the quality of the finished products of the two panels during the construction process. BRIEF DESCRIPTION OF THE DRAWINGS
