DETAILED DESCRIPTION

[0043] ​​​Figure 1 is a perspective view of a floating photovoltaic support according to the present application, Figure 2 is a side view of a floating photovoltaic support according to the present application, see Figure 1 and Figure 2 A floating photovoltaic support according to the present application comprises a floating assembly 1 and a connecting support 2, the floating assembly 1 comprises a plurality of pairs of wiring pipes 11 arranged in pairs, split frames 12 (also hollow structures and can float on water) and flexible sealing units 13, each split frame 12 is split with the corresponding wiring pipe 11 to form a floating frame, the connecting support 2 is erected on the floating frame and can be connected with the solar cell panel 3 through the connecting support 2, and the solar cell panel 3 is connected with the power cable 4.

[0044] The wiring cavity suitable for accommodating the power cable 4 is formed in the wiring pipe 11, the flexible sealing unit 13 is connected between the two adjacent wiring pipes 11, the accommodating cavity suitable for accommodating the power cable 4 is formed between the flexible sealing units 13, so as to communicate the wiring cavities of the two adjacent wiring pipes 11 through the accommodating cavity, and the flexible sealing unit 13 can be bent to be flush with the ports of the two connecting ends, directly using the wiring pipe 11 as a part of the floating assembly 1, so as to make the structure of the whole floating photovoltaic support more simple, and since the flexible sealing unit 13 can be bent to be flush with the ports of the two connecting ends, the power cable 4 can be first inserted into the wiring pipe 11, and the adjacent wiring pipes 11 can be stacked for loading and transportation, and after arriving at the construction site, only the whole formed by the wiring pipe 11 and the flexible sealing unit 13 needs to be unfolded, so as to greatly reduce the time of on-site installation and make the on-site installation more convenient.

[0045] Similarly, the adjacent split frames 12 can be hinged, so that the adjacent split frames 12 can be folded and stacked together for transportation, and when transported to the site for assembly, only the split frames 12 stacked together need to be unfolded, so that the on-site installation of the split frames 12 is more convenient.

[0046] In addition, since the two adjacent wiring pipes 11 are connected by the flexible sealing unit 13 and the adjacent split frames 12 are hinged, when the floating assembly 1 is hit by waves, the multiple floating frames connected in series can fluctuate with the waves, so that the problem that the entire floating photovoltaic support is set as a rigid whole and the waves passing through the floating photovoltaic support hit the solar cell panel 3 on the wiring pipe 11 to cause damage to the device and the circuit can be effectively avoided.

[0047] Figure 3 is a cross-sectional view of a water outlet bending part in a floating photovoltaic support according to the present application, Figure 2 cut along the C-C direction in FIG. Figure 4is a connection between a wiring pipe and a flexible sealing unit in a floating photovoltaic support of the present application Figure 2 is a sectional view obtained by cutting along the C-C direction in Figure 3 and Figure 4 The wiring pipe 11 comprises an outer pipe 113, an inner pipe 114 and an annular sealing plate 115, the inner pipe 114 is arranged in the outer pipe 113, and the end of the inner pipe 114 is connected with the inner ring of the annular sealing plate 115, and the end of the outer pipe 113 is connected with the outer ring of the annular sealing plate 115, so as to form a watertight cabin enclosed by the outer pipe 113, the inner pipe 114 and the annular sealing plate 115. The double-layer design makes the inner pipe 114, in which the power cable 4 is arranged, not easy to be filled with water, so as to prevent the power cable 4 from being damaged by water. In addition, a support ring (not shown in the figure) can be arranged in the watertight cabin, so as to be connected with the outer wall of the inner pipe 114 through the inner ring of the support ring, and connected with the inner wall of the outer pipe 113 through the outer ring of the support ring, so as to divide the watertight cabin into multiple sections, thereby improving the sinking resistance effect.

[0048] The flexible sealing unit 13 can be specifically provided with a flexible sealing pipe 131 (which can be made of rubber material) and a connecting compression ring 132. The two ends of the flexible sealing pipe 131 are provided with compression flanges 1311, the connecting compression ring 132 is provided with a pipe passing hole suitable for the flexible sealing pipe 131 to pass through and a compression ring through hole suitable for the bolt 5 to pass through, the compression flange 1311 is provided with a flange through hole matched with the compression ring through hole, and the end of the wiring pipe 11 is further provided with a pipe flange 111, the pipe flange 111 is provided with a flange through hole matched with the compression ring through hole. The bolt 5 can pass through the compression ring through hole, the flange through hole and the flange through hole in sequence and be connected with a nut, so as to realize the connection between the flexible sealing pipe 131 and the wiring pipe 11, thereby realizing the flexible sealing connection between the adjacent wiring pipes 11 through the flexible sealing pipe 131.

[0049] It can be understood that the floating assembly 1 further comprises a tensile chain 14 and a collision protection ring 15, and the tensile chain 14 is connected between the ends of the adjacent two wiring pipes 11. When the tensile chain 14 is in tension, the flexible sealing pipe 131 is in a normal state or a compressed state, so as to prevent the flexible sealing pipe 131 from being pulled off due to the water wave affecting the adjacent two wiring pipes 11 and the spacing between the two wiring pipes 11 being too large.

[0050] Figure 5 is an enlarged view of the A area in Figure 1 is an enlarged view of the A area in Figure 4 and Figure 5The anti-collision guard 15 is arranged at the end of each routing pipe 11, and includes a guard flange 151, guard support plates 152, and an anti-collision ring 153. The anti-collision ring 153 is connected to the guard support plates 152 at equal intervals in the circumferential direction, and the other ends of the guard support plates 152 are connected to the guard flange 151. The anti-collision guard 15 is connected to the pipe flange 111 via the guard flange 151, the guard flange 151 is clamped between the connecting compression ring 132 and the pipe flange 111, and the compression flange 1311 is clamped between the connecting compression ring 132 and the guard flange 151. The arrangement of the anti-collision guard 15 at the end of the routing pipe 11 can prevent the flexible sealing pipe 131 from being damaged due to the small distance between two adjacent routing pipes 11 caused by the influence of water waves. In addition, it can be understood that the anti-collision ring 153 can be provided with a gap 1531 suitable for the flexible sealing pipe 131 to pass through, so that when the adjacent routing pipes 11 are stacked together, the deformation of the flexible sealing pipe 131 and the power cable 4 passing through it will not be too large, so that the flexible sealing pipe 131 and the power cable 4 passing through it are not easily damaged.

[0051] Referring to Figure 1 and Figure 3 , the routing pipe 11 is also formed with a water outlet bending portion 112, which can float out of the water surface when the routing pipe 11 is placed in the water. The water outlet bending portion 112 is provided with a wire passing port suitable for the power cable 4 to pass through, and the power cable 4 can be connected to the solar cell panel 3 through the wire passing port. The wire passing port can be above the horizontal plane, so that water is not easy to enter the routing pipe 11 from the wire passing port, thereby preventing the power cable 4 from being damaged by water.

[0052] Referring to Figure 1 and Figure 6 , each split frame 12 can be provided to include a receiving section 121 and a connecting section 122, and each receiving section 121 is provided with one connecting section 122 at each end to connect to the routing pipe 11 via the connecting section 122. The two connecting sections 122 between adjacent split frames 12 are hinged to allow one of the adjacent split frames 12 to rotate around the axis of the connecting section 122 of the other split frame 12.

[0053] Specifically, the adjacent split frames 12 can be connected by the connecting buckle 16, and small-diameter sections are arranged on each connecting section 122 to form a limiting groove at the small-diameter sections. The connecting buckle 16 comprises a pair of buckling rings connected to each other. It should be noted that, in order to cooperate with the flexible sealing unit 13, a certain spacing exists between the connecting sections 122 of the adjacent two split frames 12, and therefore the pair of buckling rings can be connected to a connecting rod, and the end portions of the connecting rod are hingedly connected to the buckling rings. Then, one of the buckling rings is connected to one of the adjacent connecting sections 122, and the other buckling ring is connected to the other connecting section 122. The buckling rings are connected to the limiting grooves, and the inner diameter of the buckling rings is greater than the diameter of the small-diameter sections and less than the diameter of the connecting sections 122 (i.e. the diameter of the large-diameter sections outside the small-diameter sections of the connecting sections 122), so that the adjacent floating frames can move relative to each other along the axial direction of the connecting sections 122, so as to better follow the water waves, and the above connecting mode can realize the superposition of the adjacent two split frames 12, so as to facilitate the pre-installation between the split frames 12, thereby facilitating the on-site installation of the floating photovoltaic support.

[0054] The floating photovoltaic support in the above technical solution, the second aspect of the present application provides a floating photovoltaic support installation method, which comprises the following steps:

[0055] The pre-installation step: in the installation workshop, the adjacent two wiring pipes 11 are connected through the flexible sealing unit 13, and after the connection is completed, the power transmission cable 4 is inserted into the whole formed by the wiring pipe 11 and the flexible sealing unit 13, and then the adjacent wiring pipes 11 are stacked together for loading, and the split frame 12, the connecting support 2 and the solar cell panel 3 are loaded.

[0056] The on-site installation step: after the transport vehicle arrives at the site, the whole formed by the wiring pipe 11 and the flexible sealing unit 13 and the split frame 12 and the connecting support 2 are unloaded, then the whole formed by the wiring pipe 11 and the flexible sealing unit 13 is unfolded, the split frame 12 is connected with the wiring pipe 11 in sequence to form a floating frame, the connecting support 2 is installed on the floating frame, and the solar cell panel 3 is installed on the connecting support 2, and then the floating frame with the solar cell panel 3 installed is put into the water.

[0057] The anchoring step: an anchoring seat is arranged on the shore, and the floating frame is connected with the anchoring seat by using a cable.

[0058] The plurality of wiring pipes 11 are connected to form a whole through the flexible sealing unit 13 in the form of pre-installation, and the whole formed by the wiring pipe 11 and the flexible sealing unit 13 can be folded for loading and transportation, and after being transported to the site, the whole formed by the wiring pipe 11 and the flexible sealing unit 13 can be unfolded for installation, thereby greatly facilitating the on-site installation.

[0059] The working principle of the floating photovoltaic support of the present application is as follows:

[0060] Directly taking the wiring pipe 11 as a part of the floating assembly 1 can make the structure of the whole floating photovoltaic support simpler, and the connection between the two adjacent wiring pipes 11 by the flexible sealing unit 13 can make the wiring pipes 11 connected in series fluctuate with the water waves when the floating assembly 1 is hit by the water waves, thereby effectively avoiding the problem that the wiring pipe 11 is set as a whole, and the water waves passing through the wiring pipe 11 hit the solar cell panel 3 on the wiring pipe 11 to cause damage to the device and the circuit. In addition, the flexible sealing unit 13 can be bent to be flush with the ports of the two connecting ends, so the power transmission cable 4 can be first inserted into the wiring pipe 11, and the adjacent wiring pipes 11 can be stacked for transportation, and after arriving at the construction site, only the whole made of the wiring pipe 11 and the flexible sealing unit 13 needs to be unfolded, which can greatly reduce the time of on-site installation and make the on-site installation more convenient.

[0061] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
