Description

Technical Field

[0001] The invention 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, an offshore photovoltaic panel installation method and an offshore photovoltaic panel locking structure are now provided. Summary of the invention

[0006] The purpose of the present invention is to provide an installation method of offshore photovoltaic panels and a recyclable offshore photovoltaic panel locking structure. The purpose is to reduce the reliance on ship cranes for the installation of supplementary panels at the lifting port of photovoltaic panels during offshore operations. The photovoltaic panels to be installed are temporarily fixed on the existing photovoltaic platform and lifted onto the pile foundation along with the platform body. After the lifting of the main body is completed, the temporary fixing device is removed to complete the supplementary installation of the photovoltaic panels at the lifting port.

[0007] On the one hand, the present invention is achieved through the following measures: a method for installing offshore photovoltaic panels, characterized in that the photovoltaic panels with missing lifting ports are set on adjacent photovoltaic panels through detachable fixed connections and lifted together with the entire photovoltaic platform.

[0008] Furthermore, the photovoltaic panel missing from the lifting port is fixed on the adjacent photovoltaic panel above the lifting port. Since the offshore photovoltaic panel is at an angle of 15° with the horizontal plane, it is convenient to move the photovoltaic panel missing from the lifting port to the lifting port later.

[0009] Furthermore, the photovoltaic panel missing from the lifting opening is arranged on the adjacent photovoltaic panel through a plurality of locking structures; The locking structure 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; A sleeve is fixedly provided on one side of the U-shaped stopper, a screw is provided in 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 a threaded connection; The connecting piece is detachably fixed on the U-shaped limiting piece.

[0010] Furthermore, it also includes a U-shaped clamp fixed above the purlin, and the U-shaped limiter is clamped into the U-shaped clamp. Outer flaps are arranged on both sides of the upper end of the U-shaped clamp, and the upper photovoltaic panel can be overlapped on the outer flaps.

[0011] Furthermore, the U-shaped clamp is welded to the purlin or fixed to the purlin by screws.

[0012] 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, the upper side plate is clamped in the clamping groove of the U-shaped clamp, and the sleeve is fixed on the outside of the vertical plate.

[0013] 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.

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

[0015] Furthermore, a lower locking block is spaced apart on the screw rod and below the upper locking block. The upper locking block is rotatably disposed on the screw rod and is generally rotatably connected via a bearing.

[0016] The method for installing an offshore photovoltaic panel using the locking structure includes: The land operation part, that is, completing the photovoltaic panels other than the lifting port on land and superimposing the photovoltaic panels at the lifting port on the photovoltaic panels above the lifting port, is specifically as follows: Step 1: Fix the U-shaped clips on the purlins first; Step 2: Insert the open end of the U-shaped limiter into one side of the purlin and insert the upper side plate into the slot on the U-shaped limiter.

[0017] Step 3: insert the connecting piece from the open end of the U-shaped limiting piece and fix it by bolts or pins, so that the inner wall of the connecting piece and the inner wall of the U-shaped limiting piece are close to the outer wall of the purlin.

[0018] Step 4: Insert the screw into the sleeve so that the lower locking block contacts the upper end surface of the photovoltaic panel at the lower layer; 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.

[0019] 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.

[0020] 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.

[0021] Offshore operations: 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; 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.

[0022] Step 3: Loosen all nuts and recover the components of the locking structure from the gaps between the photovoltaic panels.

[0023] On the second aspect, the present embodiment provides a recyclable offshore photovoltaic panel locking structure, characterized in that it includes a U-shaped stopper inserted into a purlin of a steel platform, and a connector sleeved on an open end of the U-shaped stopper; A sleeve is fixedly provided on one side of the U-shaped stopper, a screw is provided in 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 a threaded connection; The connecting piece is detachably fixed on the U-shaped limiting piece.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] Furthermore, a baffle is fixedly provided above the upper side plate and outside the connecting member.

[0029] 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.

[0030] 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
