Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a sliding installation device and an installation method for an offshore cable structure photovoltaic support module. Background Art

[0002] Offshore photovoltaic power generation projects have been moved from land to sea. Because the sea surface is open and has no obstructions, the sunshine is long and fully utilized, and it can significantly increase power generation, occupy less land, and is easy to combine with other industries. Promoting the development and construction of offshore photovoltaics is conducive to breaking through land constraints and expanding the space for the development of new energy. It is of great significance to optimize and adjust the energy structure, promote the construction of a strong maritime nation, and help the green, low-carbon and high-quality development of the economy and society.

[0003] After more than two years of research and practice, it has become an industry consensus that offshore photovoltaics should adopt large-span structures. Large-span cable structures have broad application prospects in the offshore photovoltaic market due to their low economic cost, safe and reliable structure, and fast and convenient construction.

[0004] The traditional installation method of offshore cable structure photovoltaic bracket generally adopts the method of construction cable hoisting or the method of sliding installation of installation trolley. The method of construction cable hoisting requires setting construction cable above the load-bearing cable, lifting the photovoltaic module from the ship to the position of the load-bearing cable, and then fixing the photovoltaic module to the load-bearing cable. This method has complex construction cable installation and relatively complex installation of crane on the construction cable. In addition, the transport ship needs to move the ship position continuously, the module hoisting time is long, and the construction cost is high. The method of sliding installation of installation trolley uses the installation trolley to realize the sliding on the construction cable, but the construction cable also needs to be installed. The installation trolley can only move within a single span and cannot travel between multiple spans, which makes the hoisting efficiency of the installation trolley low. In addition, the production cost of the installation trolley is high and the reliability is low, which also leads to excessively high construction costs. Therefore, the existing offshore cable structure photovoltaic bracket has high construction costs and slow installation efficiency. Summary of the invention

DETAILED DESCRIPTION

[0044] The following is combined with Figure 1-17 The present invention is described in further detail.

[0045] Please refer to the attached figure in the instruction manual Figure 1-17 An embodiment of the present invention is as follows: a sliding installation device of an offshore cable structure photovoltaic support module, comprising a load-bearing cable 4, on which a self-sliding photovoltaic module module 7 is movably arranged, the self-sliding photovoltaic module module 7 comprises a plurality of photovoltaic module panels 1, a module frame 2 and a sled body 3, the plurality of photovoltaic module panels 1 are installed in the module frame 2, the sled body 3 is installed at the bottom of the module frame 2, the module frame 2 comprises two cross beams 21, a plurality of diagonal braces 22 and a connecting plate 23, the connecting plate 23 is provided with bolts, the photovoltaic module panels 1 are connected to the cross beam 21 through the bolts on the connecting plate 23, and the plurality of photovoltaic module panels 1 are conveniently fixed to the cross beam 21 through the cooperation of the bolts and the connecting plate 23; the sled body 3 is connected to the cross beam 21 by welding, and a plurality of diagonal braces 22 are arranged in a W-shape between the two cross beams 21, and the two cross beams 21 are conveniently connected together through the diagonal braces 22, and the strength of the two cross beams 21 when connected is conveniently increased.

[0046] The sled body 3 is movably arranged on the load-bearing cable 4 and slides on the load-bearing cable 4. There are two sled bodies 3, which are fixedly arranged at both ends of the crossbeam 21. The two sled bodies 3 are respectively arranged on the two load-bearing cables 4, so that the sled body 3 can move along the load-bearing cables 4.

[0047] The sled body 3 includes a π-shaped slide rail 31 , both ends of which are beveled and chamfered, and both ends of the π-shaped slide rail 31 are installed with pulley brackets 33 , and the two pulley brackets 33 are both provided with pulley bodies 32 .

[0048] The π-shaped slide rail 31 is provided with a first U-shaped bolt 36 for locking the load-bearing cable 4. It should be noted that when the first U-shaped bolt 36 is not locked, the slide body 3 is in a sliding state. When the first U-shaped bolt 36 is locked, the π-shaped slide rail 31 is fixed on the load-bearing cable 4, thereby causing the slide body 3 to become a fixed state.

[0049] It should be noted that the skid body 3 can slide freely on the load-bearing cable 4 without falling off the load-bearing cable 4, and takes into account both the sliding state and the fixed state. In the fixed state, only the first U-shaped bolt 36 needs to be installed to achieve the fixation between the self-sliding photovoltaic component module 7 and the load-bearing cable 4; the structure of the π-shaped slide rail 31 restricts the load-bearing cable 4 within the π-shaped slide rail 31 throughout the sliding process, thereby preventing the pulley body 32 from accidentally falling out of the load-bearing cable 4 during sliding, thereby improving the safety of construction.

[0050] The π-shaped slide rail 31 is composed of a horizontal plate and two vertical plates, and a slide groove is formed between the two vertical plates. The width of the slide groove is greater than the width of the load-bearing cable 4 and the fixing lock of the load-bearing cable 4. The load-bearing cable 4 is located in the slide groove of the π-shaped slide rail 31 and slides with the slide groove of the π-shaped slide rail 31. The pulley 32 and the slide groove form a positioning and sliding system, so that the slide skid body 3 can slide freely on the load-bearing cable 4; the horizontal plate of the π-shaped slide rail 31 is provided with installation holes for installing the pulley body 32, the pulley bracket 33 and the first U-bolt 36.

[0051] An annular groove is provided on the outer wall of the pulley body 32, and the inner wall of the annular groove is wide on the outside and narrow on the inside. The annular groove is adapted to the width of the load-bearing cable 4 and the fixed lock buckle of the load-bearing cable 4, and the width of the annular groove is slightly larger than the width of the load-bearing cable 4 and the fixed buckle of the load-bearing cable 4. The load-bearing cable 4 is located in the annular groove and slides with the inner wall of the annular groove. The pulley body 32 is installed in the pulley bracket 33 by bolts, and the pulley bracket 33 is installed at both ends of the π-shaped slide rail 31 by bolts. The inner surface of the annular groove of the pulley body 32 is slightly lower than the lower surface of the horizontal plate of the π-shaped slide rail 31.

[0052] It should be noted that the design of the detachable pulley body 32 allows the pulley body 32 to slide freely on the load-bearing cable 4. After sliding into place, the connecting bolts of the pulley bracket 33 are loosened to remove the pulley body 32 and the pulley bracket 33. Therefore, the pulley body 32 and the pulley bracket 33 can be reused, thereby saving costs.

[0053] A traction rope 5 is provided on the photovoltaic module panel 1, and ear plates 34 are welded at both ends of the π-shaped slide rail 31. The ear plates 34 are located on the inner side of the cross beam 21 of the module frame 2 and are tightly attached to the side of the cross beam 21 of the module frame 2. The side wall of the ear plate 34 is welded to the cross beam 21, and a hook groove opening downward is provided on the outer side of the ear plate 34.

[0054] It should be noted that by welding the bottom of the ear plate 34 to the π-shaped slide rail 31 and its side to the crossbeam 21 of the module frame 2, a reliable connection between the crossbeam 21 of the module frame 2 and the slide body 3 is achieved, and there is no need to set up a separate connecting cross plate for connection; a downward-opening hook groove is left on the outer side of the ear plate 34, and the hook groove can be used to conveniently hang the hook without the need for a shackle, making it easy to unhook the hook, and no manual operation is required during unhooking, which is convenient to operate.

[0055] A fixing bolt 35 for fixing the traction rope 5 is provided at the top of the ear plate 34, and the fixing bolt 35 is located on the inner side of the cross beam 21 of the module frame 2. The fixing bolt 35 is composed of a screw and a nut. The lower end of the screw is welded to the top of the ear plate 34, and the outer wall of the screw is welded to the cross beam 21. The nut is threadedly sleeved on the upper end of the screw. An annular cylindrical connector is provided at the connection between the traction rope 5 and the photovoltaic module panel 1. The annular cylindrical connector is movably sleeved on the screw and locked by the nut. The traction rope 5 is installed at the position where it is connected to the self-gliding photovoltaic module module 7. The connection between the traction rope 5 and the photovoltaic module panel 1 is completed by inserting the annular cylindrical connector into the screw of the fixing bolt 35 and tightening the nut; when the operator moves to the traction rope 5 through the construction platform and loosens the nut, the annular cylindrical connector can be removed from the screw of the fixing bolt 35, thereby completing the disconnection between the traction rope 5 and the photovoltaic module panel 1.

[0056] It should be noted that the use of a quick technology of combining the traction rope 5 with the fixing bolt 35 allows the connection and disconnection of the traction rope 5 to be completed by only tightening the nut and loosening the nut, and installation and disassembly are quick and convenient.

[0057] A sled stopper 6 for blocking the self-sliding photovoltaic assembly module 7 is installed on the load-bearing cable 4. The installation position of the sled stopper 6 is at the planned installation position of the self-sliding photovoltaic assembly module 7; the sled stopper 6 includes a second U-bolt 61 and a barb 62. The second U-bolt 61 is installed on the load-bearing cable 4, and the barb 62 is welded to the second U-bolt 61. The barb 62 is formed by bending a smooth steel bar, and the opening of the barb 62 faces the direction of the sled body 3.

[0058] In order to better demonstrate a sliding installation device for an offshore cable structure photovoltaic support module, this embodiment now proposes a sliding installation device and an installation method for an offshore cable structure photovoltaic support module, including the following steps:

[0059] Step 1: manufacture and install the self-gliding photovoltaic module 7 in an onshore factory, transport the self-gliding photovoltaic module 7 in a sliding state to the site as a whole, and then hoist it to one end of the cable structure photovoltaic support through a hoisting device and place it on two load-bearing cables 4;

[0060] Step 2: Insert the annular cylindrical connector of the traction rope 5 onto the screw of the fixing bolt 35, and then tighten the nut of the fixing bolt 35 to complete the connection between the traction rope 5 and the self-gliding photovoltaic assembly module 7;

[0061] Step 3: Install the skid stopper 6 at the location where the self-gliding photovoltaic assembly module 7 is planned to be installed;

[0062] Step 4: Under the traction of the traction rope 5, the self-sliding photovoltaic assembly module 7 slides on the two load-bearing cables 4. When the self-sliding photovoltaic assembly module 7 slides to the position of the sled stopper 6, the sled body 3 is blocked and the sliding stops, indicating that the self-sliding photovoltaic assembly module 7 has slid to the planned installation position;

[0063] Step 5: Install the first U-bolt 36 to preliminarily connect the skid body 3 to the load-bearing cable 4, then loosen the nut on the fixing bolt 35, so as to facilitate the circular cylindrical connector of the traction rope 5 to be removed from the screw of the fixing bolt 35. At this time, the traction rope 5 is disconnected from the photovoltaic module panel 1, and then the connecting bolts of the pulley bracket 33 are loosened, and then the pulley body 32 and the pulley bracket 33 are removed, so that the pulley body 32 and the pulley bracket 33 can be reused, and then the first U-bolt 36 is tightened again to fix the skid body 3 firmly on the load-bearing cable 4;

[0064] Step 6: Pull the traction rope 5 back to the starting point and repeat the installation of the next self-gliding photovoltaic assembly module 7.

[0065] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
