Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic installation, and in particular to a photovoltaic power generation panel installation and connection structure. Background Art

[0002] Photovoltaic panels are a type of equipment that uses solar energy to generate electricity, primarily converting sunlight into electrical energy through the photoelectric effect. Common photovoltaic installations are fixed on land via brackets, or fixed on the water surface via floats. Waterborne photovoltaics can not only form a "fish-light complementary" farming method, but can also utilize idle water surfaces formed after some coal mines collapse due to mining.

[0003] The patent document with announcement number CN110048664B discloses a water surface photovoltaic bracket with a plug-in mortise and tenon structure and its installation method, including a main floating body, a photovoltaic module front bracket and a photovoltaic module rear bracket. The photovoltaic module front bracket and the photovoltaic module rear bracket are installed on the main floating body in a plug-in mortise and tenon manner. Strip installation grooves are opened on the four sides of the main floating body. A threaded hole I is opened on the outer side of each strip installation groove. The bottoms of the legs of the photovoltaic module front bracket and the photovoltaic module rear bracket are provided with threaded holes II. After the legs are inserted into the corresponding strip installation grooves, the bolts are inserted from the threaded hole I until they are screwed into the threaded hole II. This application has the effect of quickly assembling and supporting the photovoltaic bracket through the plug-in mortise and tenon installation form.

[0004] As in the prior art of the above-mentioned patent, before installing the photovoltaics, it is necessary to fix the bracket on the main float and then fix the photovoltaics, but this step is only one of the installation steps of the water photovoltaics. In order to ensure the stability of the photovoltaic array, auxiliary floats are usually fixed on both sides of the main float. At the same time, in order to ensure that the auxiliary floats of a single module can be disassembled and repaired separately and easy to transport, a splicing method is usually adopted. Before the water photovoltaics form an array: first fix the photovoltaics to the main float, then fix the main float to the first auxiliary float, and then fix the main float and the second auxiliary float. Finally, when the array is formed, the parallel auxiliary floats are connected. Not only are there more installation steps, but it also makes the subsequent disassembly and repair process of the single module cumbersome. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a photovoltaic panel installation and connection structure, which solves the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Example 1: Please refer to Figures 1 to 9 , Figure 12 The present invention provides a technical solution: a photovoltaic panel installation and connection structure, comprising a main floating body 1 and a first auxiliary floating body 11 and a second auxiliary floating body 12 respectively arranged on both sides of the main floating body 1, wherein both sides of the main floating body 1 are movably provided with a supporting assembly for installing a photovoltaic panel 13, and further comprising:

[0038] The lifting assembly is provided on one side of the main floating body 1 and is used to lift the supporting assembly to drive one side of the photovoltaic panel 13 to lift and simultaneously fix the first auxiliary floating body 11;

[0039] The connecting assembly is provided on one side of the main floating body 1. When the supporting assembly drives one side of the photovoltaic panel 13 to rise, the connecting assembly passively fixes the second auxiliary floating body 12.

[0040] The lifting assembly includes a stud 2 fixedly mounted on one side of the main floating body 1 and a core 21 movably mounted on the surface of the stud 2. The upper surface of the core 21 is hinged with a support arm 22, and the other end of the support arm 22 is hinged with a bearing plate 23. The supporting assembly includes a first clip 24 and a second clip 25. The first clip 24 is hinged to the bearing plate 23, and the second clip 25 is hinged to the main floating body 1.

[0041] The connection assembly includes a connection frame 3 fixedly mounted on one side of the main floating body 1 , a connection piece 31 fixedly connected to the surface of the second auxiliary floating body 12 , and a locking frame 32 fixedly mounted on the second buckle 25 .

[0042] Specifically, a groove is provided on one side of the main buoy 1 close to the first auxiliary buoy 11, and the stud 2 is fixedly installed in the groove. There are two ferrules 21, which are distributed on both sides of the stud 2, and nuts 27 are threadedly connected on both sides of the outer surface of the stud 2. The ferrule 21 can be limited by the nut 27. In addition, a locking block 26 is fixed to the middle of the first auxiliary buoy 11. A card slot that matches the stud 2 and a slot that matches the ferrule 21 are provided in the middle of the locking block 26. The size of the slot is larger than the size of the card slot and is used to lock the first auxiliary buoy 11. The connecting frame 3 is fixedly installed on one side of the main buoy 1 close to the second auxiliary buoy 12, and empty slots are provided in the middle and top of the main buoy. The connecting piece 31 is inserted into the connecting frame 3 through the empty slot.

[0043] Furthermore, the first clip 24 and the second clip 25 are at the same height. When installing the photovoltaic panel 13, the photovoltaic panel 13 is first horizontally inserted into the first clip 24 and the second clip 25 to complete the initial clamping, and then the first auxiliary float 11 is inserted into the middle of the outer surface of the stud 2 through the slot opened on the locking block 26, and then the connecting piece 31 is inserted into the empty slot of the connecting frame 3, and then the carrier plate 23 is lifted so that one end of the photovoltaic panel 13 is lifted and tilted around the connection point between the second clip 25 and the main float 1. In this process, the first clip 24 will tilt, thereby adapting to the overall tilt of the photovoltaic panel 13, avoiding interference between the first clip 24 and the end of the photovoltaic panel 13, and the core 21 will drive the support arm 22 during the lifting process of the carrier plate 23, so that the support arm 22 drives the core 21 to slide on the stud 2 and insert it into the slot of the locking block 26 to complete the locking of the first auxiliary float 11, and then tighten the nut 27 so that the nut 27 contacts the core 21 to complete the position limitation of the core 21, and at the same time, the photovoltaic panel 13 is supported by the support arm 22 and keeps tilted;

[0044] More specifically, when the photovoltaic panel 13 is lifted, the second clip 25 tilts and rotates around its connection point with the main float 1, driving the locking frame 32 to rotate, so that the locking frame 32 locks the connecting piece 31 through the empty slot above the connecting frame 3, thereby completing the fixation of the second auxiliary float 12;

[0045] The present invention lifts one end of the photovoltaic panel 13 so that the support arm 22 is driven, and while supporting the photovoltaic panel 13 to tilt, the drive core 21 is inserted into the slot provided on the locking block 26 to lock the first auxiliary float 11, and at the same time, the locking frame 32 passively locks the second auxiliary float 12; while installing the photovoltaic panel 13, the two auxiliary floats are fixed to the main float. Compared with the prior art, not only the step of installing the bracket on the main float is omitted, but also the two auxiliary floats can be fixed to the main float at the same time, which simplifies the installation steps, improves the installation efficiency, and facilitates subsequent disassembly and maintenance. The support arm 22 adopts a connecting rod design, which can support the photovoltaic panel 13 at an angle when in use, and is in a horizontal position during transportation, which is convenient for transportation.

[0046] Example 2: Please refer to Figure 7 and Figure 8 , also includes a protection module, the protection module includes a fixing frame 4 fixedly mounted on the bottom of the first clip 24, and a slide rail 41 fixedly mounted on the surface of the fixing frame 4, and a protective box 42 is provided on the slide rail 41; an interference member 43 is fixedly mounted on the surface of the carrying plate 23, and the other end of the interference member 43 is attached to the bottom of the protective box 42; an electrical connector 44 is provided at the bottom of the photovoltaic panel 13, and when the carrying plate 23 is not driven, there is a gap between the electrical connector 44 and the protective box 42; specifically, in the initial state, there is a gap between the protective box 42 and the electrical connector 44 to prevent the electrical connector 44 from being interfered with by the protective box 42 when the photovoltaic panel 13 is inserted into the first clip 24 and the second clip 25; the protective box 42 is connected between the fixing frame 4 and the first clip 24, and the protective box 42 is slidably mounted on the slide rail 4 through a slider. 1, and is directly below the electrical connector 44. When the photovoltaic panel 13 is lifted and the first clip 24 is tilted, the protective box 42 will tilt along with the first clip 24, and the interference member 43 is fixed to the support arm 22 and is in a vertical rising state. When the protective box 42 is tilted, under the interference of the interference member 43, the protective box 42 will slide upward on the surface of the slide rail 41 in the tilting direction of the photovoltaic panel 13, thereby covering and protecting the electrical connector 44 to avoid the electrical connector 44 from being unstable due to the influence of wind and waves or the climbing and jumping of aquatic organisms in the "fish-light complementary" farming method, resulting in the problem of virtual connection and leakage. Furthermore, the end of the interference member 43 that is attached to the bottom of the protective box 42 can be made into a cylindrical or arc end, which can reduce the friction between the protective box 42 and the interference member 43 during relative sliding.

[0047] Example 3: Please refer to Figure 9 and Figure 10, also includes a self-locking component, the self-locking component includes a mounting groove 5 opened in the second buckle 25, and a return spring 51 connected to the mounting groove 5, the upper end of the return spring 51 is fixedly connected to a follower 52; a driving member 53 is movably installed on one side of the follower 52, and the other end of the driving member 53 is fixedly connected to a moving block 54, and a self-locking member 55 is fixedly connected to one side of the follower 52; a traction rope 6 fixedly connected to the surface of the first auxiliary float 11, and a fastening bolt 61 fixedly connected to the other end of the traction rope 6, a screw hole adapted to the fastening bolt 61 is opened on the surface of the first buckle 24; specifically, the follower 52 and the driving member 53 are in the shape of the end portion of the mounting groove 5 They are all in the shape of a right triangle, and the inclined surface of the driving member 53 is fitted below the inclined surface of the follower 52, which is used to drive the follower 52. The end of the right triangle of the driving member 53 is provided with a protrusion to limit the driving member 53, which can prevent it from driving the moving block 54 to disengage from the first buckle 24. On the basis of Example 1, when the photovoltaic panel 13 is lifted and tilted, under the influence of gravity, the photovoltaic panel 13 will squeeze the moving block 54, so that the moving block 54 drives the driving member 53. When the driving member 53 moves, it drives the follower 52, so that the follower 52 drives the self-locking member 55 to move downward, and locks the photovoltaic panel 13 through the locking groove 56, thereby improving its stability.

[0048] Furthermore, when the photovoltaic panel 13 slides due to gravity, its end is difficult to fully fit with the first clip 24. By tightening the fastening bolt 61, the fastening bolt 61 is pressed against the photovoltaic panel 13, further improving the stability of the photovoltaic panel 13. At the same time, through the connection of the traction rope 6, the main float 1 and the first auxiliary float 11 are connected more tightly. It should be noted that in this process, the movement of the photovoltaic panel 13 will drive the electrical connector 44 to move. Therefore, when the protective box 42 is manufactured, its inner cavity width must be greater than the width of the electrical connector 44, and it must be ensured that after the electrical connector 44 moves, the protective box 42 can still cover and protect it.

[0049] Example 4: Please refer to Figure 2 、 Figure 6 、 Figure 9 and Figure 10, and also includes a fastening module, the fastening module includes a connecting belt 7 fixedly connected to the surface of the connecting piece 31, and an extrusion groove 71 opened on the surface of the locking frame 32, and the surface of the self-locking member 55 is fixedly connected to the extrusion member 72; specifically, the extrusion groove 71 and the extrusion member 72 are adapted to each other. On the basis of Example 1, before lifting the photovoltaic panel 13, when the connecting piece 31 is inserted into the empty slot in the middle of the connecting frame 3, the connecting piece 31 can be inserted into the extrusion groove 71. In the subsequent Example 2, when the self-locking member 55 moves downward to lock the photovoltaic panel 13, it will drive the extrusion member 72 to move downward and insert into the extrusion groove 71. The extrusion groove 71 and the extrusion member 72 are used to fix the connecting belt 7, which can make the connection between the second auxiliary float 12 and the main float 1 tighter.

[0050] Example 5: Please refer to Figure 1 、 Figure 6 and Figure 11 , the surfaces of the first auxiliary float 11 and the second auxiliary float 12 are fixedly mounted with a first mounting buckle 8, and the four corners of the main float 1 are fixedly mounted with a second mounting buckle 81; the ends of the first auxiliary float 11 and the second auxiliary float 12 are both provided with a connecting float 9, and a limiting groove 91 is provided inside the connecting float 9; specifically, corresponding connecting holes are provided on the first mounting buckle 8 and the second mounting buckle 81 for multi-point fixation between the main float 1 and the first auxiliary float 11 and the second auxiliary float 12, and the end of the second mounting buckle 81 is T-shaped and a friction cloth is pasted on it to reduce the shaking amplitude between the modules;

[0051] In the above embodiment, after the photovoltaic and main floats, and the main floats and two auxiliary floats are fixed on the shore, they need to be pushed into the water to fix the auxiliary floats to each other and form a square array. When fixed on the water, due to the influence of the water surface, the auxiliary floats are prone to rocking against each other, which affects the installation. In the present invention, whether to use multi-point installation is determined according to the actual degree to which the water surface is affected by wind. As for the installation between the auxiliary floats, after aligning the second mounting buckles 81 on the main floats 1 of different modules, the connecting float 9 is clamped into the outer side of the second mounting buckle 81 by using the limiting groove 91 to limit the second mounting buckle 81, thereby reducing the rocking amplitude between different modules and facilitating the connection of the auxiliary floats. At the same time, the friction cloth between the contact of the second mounting buckle 81 can increase the friction coefficient and further reduce the rocking amplitude between different modules. On the one hand, it can facilitate the installation of the auxiliary floats, and on the other hand, it can reduce the subsequent rocking amplitude between modules caused by wind and waves.
