Description

Technical Field

[0001] The utility model belongs to the technical field of offshore photovoltaics, and in particular relates to a recyclable offshore photovoltaic panel locking structure. Background Art

[0002] At present, offshore photovoltaics are entering a new period of rapid development. At present, marine photovoltaics are mainly fixed with pile foundations. The structural form is that photovoltaic panels are installed on a supporting steel platform, which sits 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 operating environment, including strong waves, typhoons, sea ice, high humidity, and frequent temperature changes, offshore photovoltaic work is more demanding and more difficult than ground photovoltaic work. The usual practice is to complete the assembly of photovoltaic panels except for the lifting port on land. The photovoltaic panels are fixedly installed on the purlins of the steel platform. Finally, the photovoltaic platform is lifted to the offshore pile foundation by a ship crane. After the lifting is completed, the missing photovoltaic panels at each lifting port are supplemented and installed, thus completing the last piece of the photovoltaic unit platform installation puzzle.

[0004] The traditional practice of supplementary installation of photovoltaic panels at the lifting port relies on ship cranes, and the main activity of offshore operations is lifting operations. Lifting operations by ship cranes are the key process for controlling construction schedule nodes. Lifting photovoltaic panels one by one will greatly restrict the construction progress on site. In addition, facing severe weather and high-altitude operations at sea, traditional lifting operations also have the risk of photovoltaic panels falling from high altitudes, and there are many steel structure rods under the photovoltaic modules, which makes construction very difficult.

[0005] Therefore, in order to solve the problem that the installation operation of the supplementary plate at the lifting port occupies the ship crane and thus affects the overall construction progress, and also to shorten the offshore operation time, a recyclable offshore photovoltaic panel locking structure is now provided. Utility Model Content

[0006] The purpose of the utility model is to provide a recyclable offshore photovoltaic panel locking structure, which aims to reduce the reliance on ship cranes for the installation of supplementary panels at the lifting port of photovoltaic panels during offshore operations, by temporarily fixing the photovoltaic panels to be installed on the existing photovoltaic platform, and lifting them to the pile foundation along with the platform body, and after the main body is lifted, the temporary fixing device is removed to complete the supplementary installation of the photovoltaic panels at the lifting port.

[0007] This embodiment provides a recyclable offshore photovoltaic panel locking structure, characterized in that it includes a U-shaped stopper inserted into the purlin of the steel platform, and a connecting piece sleeved on the open end of the U-shaped stopper;

[0008] One side of the U-shaped limiting member is fixedly provided with a sleeve, a screw rod is penetrated 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 threadedly connected with a locking nut;

[0009] The connecting member is fixedly arranged on the U-shaped limiting member in a detachable manner.

[0010] Further, it further includes a U-shaped clamping member fixed above the purlin, and the U-shaped limiting member is clamped into the U-shaped clamping member.

[0011] Further, the U-shaped clamping member is welded on the purlin or fixed on the purlin by bolts. The upper end of the bolt is fixed on the U-shaped clamping member, and the lower end of the bolt penetrates through the purlin and is fixed by a nut.

[0012] 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, and the U-shaped clamping member is arranged on the upper side plate.

[0013] 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.

[0014] Further, a baffle is fixedly arranged above the upper side plate and outside the connecting member.

[0015] Further, lower locking blocks are arranged at intervals on the screw rod and below the upper locking block. The upper locking block is rotatably arranged on the screw rod.

[0016] Among them, the installation method of the offshore photovoltaic panel applying the locking structure includes:

[0017] The land operation part, that is, on land, the photovoltaic panels except at the hoisting opening and the photovoltaic panels at the upper part of the hoisting opening are superimposed and installed. Specifically:

[0018] Step 1: First, fix the U-shaped clamping member on the purlin;

[0019] Step 2: Insert the open end of the U-shaped limiting member from one side of the purlin and make the upper side plate snap into the clamping groove on the U-shaped clamping member.

[0020] Step 3: Insert the connecting member from the open end of the U-shaped limiting member and fix it by bolts or pins, so that the inner walls of the connecting member and the U-shaped limiting member are in close contact with the outer wall of the purlin.

[0021] Step 4: Insert the screw rod into the sleeve so that the lower locking block contacts the upper end face of the lower-layer photovoltaic panel;

[0022] Step 5: Lay a soft isolation medium on the lower photovoltaic panel, and place the upper photovoltaic panel on the soft isolation medium and below the upper locking block.

[0023] Step 6: Pull the screw from the bottom to make the upper locking block press the upper photovoltaic panel, and the lower locking block press the lower photovoltaic panel, and then tighten the locking nut to fix it.

[0024] Step 7: Install the rope in the mounting hole on the external frame of the photovoltaic panel. The connection between the rope and the frame is distributed in an isosceles triangle. The traction end of the rope is fixedly connected to the steel structure at the hanging point. The rope is preferably located below the photovoltaic panel. This can reduce damage to the photovoltaic panel during traction.

[0025] Offshore operations:

[0026] Step 1: After the photovoltaic platform is hoisted and the hoisting point device is released, the upper locking block is rotated to separate the upper photovoltaic panel and release the temporary locking structure;

[0027] Step 2: Use the rope and the weight of the photovoltaic panel to slowly lower the photovoltaic panel. After lowering it to the installation position, fix the end of the rope on the truss, and the photovoltaic panel to be added is in place.

[0028] Step 3: Loosen all nuts and recover the components of the locking structure from the gaps between the photovoltaic panels.

[0029] The technical solution provided by the embodiment of the utility model 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 during 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.
