Description

Technical Field

[0001] The present application relates to the field of photovoltaic power generation technology, and in particular to a floating photovoltaic bracket and a method for installing a floating photovoltaic bracket. Background Art

[0002] Photovoltaic power generation is a green form of power generation that is actively advocated today. It usually uses solar panels to generate electricity.

[0003] The use of solar panels to generate electricity requires a large area, and large-scale photovoltaic power stations are mostly suitable for building in Gobi areas. However, there are now some technologies for building large-scale photovoltaic power stations in open waters such as lakes and reservoirs.

[0004] In the prior art, solar panels are usually installed on water by piling. Therefore, it takes a long time to piling before construction, which makes the on-site construction period very long. In addition, the terrain conditions in some waters are complex and not suitable for piling operations, which makes construction difficult and further prolongs the construction period.

[0005] In view of this, a floating photovoltaic support is needed. Summary of the invention

[0006] In order to improve the problems of long construction period and construction difficulty in on-site construction, the present application provides a floating photovoltaic bracket and a floating photovoltaic bracket installation method.

[0007] A floating photovoltaic support provided in the first aspect of the present application adopts the following technical solution: a floating photovoltaic support, comprising a floating component and a connecting bracket, wherein the floating component comprises a plurality of pairs of wiring tubes, a splicing frame and a flexible sealing unit arranged in pairs, each of the splicing frames is spliced ​​with the corresponding wiring tube to form a floating frame, and adjacent splicing frames are movably connected; The connecting bracket is mounted on the floating frame and can be connected to the solar panel via the connecting bracket, and the solar panel is connected to a power transmission cable; A wiring cavity suitable for accommodating the power transmission cable is formed in the wiring tube, and two adjacent wiring tubes are connected via the flexible sealing unit. A accommodating cavity suitable for accommodating the power transmission cable is formed between the flexible sealing units, so that the wiring cavities of the two adjacent wiring tubes are connected via the accommodating cavity, and the flexible sealing unit can be bent until the ports of the two connection ends are flush.

[0008] By adopting the above technical solution, the wiring tube is directly used as a part of the floating component, so that the overall structure of the floating photovoltaic support can be simpler. The two adjacent wiring tubes are connected by a flexible sealing unit, so that when the floating component is hit by waves, the wiring tubes connected in series can rise and fall with the waves, thereby effectively avoiding the problem of setting the wiring tube as a whole, and the waves covering the wiring tube when passing through the wiring tube and hitting the solar cell panel to cause damage to the device and circuit. In addition, the flexible sealing unit can be bent to be flush with the ports of the two connecting ends, so that the transmission cable can be passed through the wiring tube first, and it is convenient to stack the adjacent wiring tubes for loading and transportation. After arriving at the construction site, it is only necessary to unfold the wiring tube and the flexible sealing unit to form a whole, which can greatly reduce the time of on-site installation and make on-site installation more convenient.

[0009] Furthermore, the flexible sealing unit includes a flexible sealing tube and a connecting pressure ring, and the ends of both ends of the flexible sealing tube are provided with crimping flanges. The connecting pressure ring is formed with a pipe penetration hole suitable for the flexible sealing tube to pass through and a pressure ring through hole suitable for the bolt to pass through. The crimping flange is formed with a flange through hole matching the pressure ring through hole. A pipe flange is formed at the end of the wiring pipe, and the pipe flange is provided with a flange through hole matching the pressure ring through hole. The bolt can pass through the pressure ring through hole, the flange through hole and the flange through hole in sequence to connect with the nut to realize the connection between the flexible sealing tube and the wiring pipe.

[0010] By adopting the above technical solution, a flexible sealed connection between two wiring tubes can be achieved.

[0011] Furthermore, the floating assembly also includes an anti-zipper, and the anti-zipper is connected between the ends of two adjacent wiring tubes. When the anti-zipper is in a tensioned state, the flexible sealing tube is in a normal state or a compressed state.

[0012] By adopting the above technical solution, the anti-zipper can be used to prevent the flexible sealing tube from being broken due to the large distance between two adjacent wiring tubes.

[0013] Furthermore, the floating component also includes an anti-collision guard ring, and the end of each wiring pipe is provided with the anti-collision guard ring, and the anti-collision guard ring includes a guard ring flange protection support plate and an anti-collision ring, and a plurality of the protection support plates are connected at equal intervals in the circumferential direction of the anti-collision ring, and the other end of each protection support plate is connected to the guard ring flange; the anti-collision guard ring is connected to the pipeline flange via the guard ring flange, and the guard ring flange is abutted and clamped between the connecting pressure ring and the pipeline flange, and the crimping flange is abutted and clamped between the connecting pressure ring and the guard ring flange.

[0014] By adopting the above technical solution, it is possible to prevent the flexible sealing tube from being crushed due to the small distance between two adjacent wiring tubes.

[0015] Furthermore, the anti-collision ring is provided with a clearance opening suitable for the flexible sealing tube to pass through.

[0016] By adopting the above technical solution, when adjacent wiring tubes are stacked together, the deformation of the flexible sealing tube and the power transmission cables passing therein will not be too large, so that the flexible sealing tube and the power transmission cables passing therein are not easily damaged.

[0017] Furthermore, a water outlet bend is formed on the wiring pipe. When the wiring pipe is placed in water, the water outlet bend can float out of the water surface. A wire passage opening suitable for the transmission cable to pass through is provided at the water outlet bend.

[0018] By adopting the above technical solution, the transmission cable can pass through the cable opening and be connected to the solar panel.

[0019] Furthermore, the wiring pipe includes an outer tube, an inner tube and an annular sealing plate to form the wiring cavity through the inner tube. The inner tube is arranged in the outer tube, and the end of the inner tube is connected to the inner circle of the annular sealing plate, and the end of the outer tube is connected to the outer circle of the annular sealing plate, so that a watertight compartment can be enclosed by the outer tube, the inner tube and the annular sealing plate.

[0020] By adopting the above technical solution, the inner tube through which the power transmission cable is passed is not easily infiltrated with water, so that the power transmission cable is not easily damaged by water.

[0021] Furthermore, each of the splicing frames includes a receiving section and a connecting section, and each of the two ends of the receiving section is provided with a connecting section to be connected to the wiring tube via the connecting section. The two connecting sections between adjacent splicing frames are hinged, and one of the adjacent splicing frames can rotate around the axis of the connecting section in the other.

[0022] By adopting the above technical solution, it is possible to achieve the overlapping of two adjacent splicing frames, so as to facilitate the pre-installation of the splicing frames, thereby facilitating the on-site installation of the floating photovoltaic support.

[0023] Furthermore, the floating assembly further comprises a connecting buckle, and adjacent splicing frames are connected via the connecting buckle; Each of the connecting segments is provided with a small diameter segment to form a limiting groove at the small diameter segment, and the connecting buckle comprises a pair of connected buckles, one of the pair of buckles is connected to one of the adjacent connecting segments, and the other of the pair of buckles is connected to the other of the adjacent connecting segments; The buckle ring is connected in the limiting groove, and the inner diameter of the buckle ring is greater than the diameter of the small diameter section and smaller than the diameter of the connecting section.

[0024] By adopting the above technical solution, adjacent floating frames can generate relative movement along the axial direction of the connecting section, so as to better achieve the following movement with the water waves.

[0025] A second aspect of the present application provides a floating photovoltaic bracket installation method, which adopts the following technical solution: A floating photovoltaic bracket installation method, which is implemented by using the floating photovoltaic bracket in the above technical solution, comprises the following steps: Pre-installation step: in the installation workshop, two adjacent wiring tubes are connected via a flexible sealing unit, after which the transmission cable is inserted into the whole formed by the wiring tube and the flexible sealing unit, and then the adjacent wiring tubes are stacked together for loading, and the splicing frame, the connecting bracket and the solar cell panel are loaded; On-site installation steps: after the transport vehicle arrives at the site, the whole formed by connecting the wiring pipe and the flexible sealing unit, the splicing frame and the connecting bracket are unloaded, and then the whole formed by connecting the wiring pipe and the flexible sealing unit is unfolded, and the splicing frame and the wiring pipe are connected in sequence to form a floating frame, and the connecting bracket is installed on the floating frame, and the solar cell panel is installed on the connecting bracket, and then the floating frame with the solar cell panel installed is put into water; Anchoring step: An anchoring seat is set on the shore, and the floating frame is connected to the anchoring seat by using a cable.

[0026] By adopting the above technical solution, multiple wiring pipes are connected into a whole through flexible sealing units in a pre-installed form, and the whole formed by the wiring pipes and the flexible sealing units can be folded for easy loading and transportation. After being transported to the site, the whole formed by the wiring pipes and the flexible sealing units can be unfolded and installed, which greatly facilitates on-site installation.

[0027] In summary, this application has the following beneficial effects: Directly using the wiring tube as a part of the floating component can make the overall structure of the floating photovoltaic support simpler. The two adjacent wiring tubes are connected by a flexible sealing unit, so that when the floating component is hit by waves, the wiring tubes connected in series can rise and fall with the waves, thereby effectively avoiding the problem of setting the wiring tube as a whole, and the waves covering the wiring tube when passing through the wiring tube and hitting the solar cell panel to cause damage to the device and circuit. In addition, the flexible sealing unit can be bent to be flush with the ports of the two connection ends, so that the transmission cable can be passed through the wiring tube first, and it is convenient to stack the adjacent wiring tubes for loading and transportation. After arriving at the construction site, it is only necessary to unfold the wiring tube and the flexible sealing unit to form a whole, which can greatly reduce the time of on-site installation and make on-site installation more convenient.

DETAILED DESCRIPTION

[0030] Figure 1 This is a three-dimensional diagram of a floating photovoltaic support of the present application. Figure 2 This is a side view of a floating photovoltaic support in this application, see Figure 1 and Figure 2 A floating photovoltaic bracket provided in the present application includes a floating component 1 and a connecting bracket 2. The floating component 1 includes a plurality of pairs of wiring tubes 11 arranged in pairs, a splicing frame 12 (also a hollow structure and capable of floating on water) and a flexible sealing unit 13. Each splicing frame 12 is spliced ​​with the corresponding wiring tube 11 to form a floating frame. The connecting bracket 2 is erected on the floating frame and can be connected to a solar panel 3 via the connecting bracket 2. A transmission cable 4 is connected to the solar panel 3.

[0031] A wiring cavity suitable for accommodating a power transmission cable 4 is formed in the wiring tube 11. Two adjacent wiring tubes 11 are connected via a flexible sealing unit 13. A accommodating cavity suitable for accommodating a power transmission cable 4 is formed between the flexible sealing units 13, so that the wiring cavities of two adjacent wiring tubes 11 are connected via the accommodating cavity, and the flexible sealing unit 13 can be bent until the ports of the two connecting ends are flush. The wiring tube 11 is directly used as a part of the floating component 1, which can make the overall structure of the floating photovoltaic bracket simpler. Since the flexible sealing unit 13 can be bent until the ports of the two connecting ends are flush, the power transmission cable 4 can be passed through the wiring tube 11 first, and it is convenient to stack the adjacent wiring tubes 11 for loading and transportation. After arriving at the construction site, it is only necessary to unfold the wiring tube 11 and the flexible sealing unit 13 as a whole, which can greatly reduce the time of on-site installation and make on-site installation more convenient.

[0032] Similarly, adjacent splicing frames 12 can be hinged so that they can be folded and stacked together for easy transportation. When transported to the site for assembly, only the stacked splicing frames 12 need to be unfolded, making the on-site installation of the splicing frames 12 more convenient.

[0033] In addition, since two adjacent wiring tubes 11 are connected by a flexible sealing unit 13 and adjacent splicing frames 12 are arranged to be hinged, when the floating component 1 is hit by waves, the multiple floating frames connected in series can rise and fall with the waves, thereby effectively avoiding the problem of setting the entire floating photovoltaic bracket as a rigid whole, and the waves covering the wiring tubes 11 when passing through the floating photovoltaic bracket and hitting the solar panel 3, causing damage to the devices and circuits.

[0034] Figure 3 The invention relates to a floating photovoltaic bracket in which the water outlet bend is along the Figure 2 The cross-sectional view obtained by cutting along the CC direction, Figure 4 The connection between the wiring tube and the flexible sealing unit in a floating photovoltaic support of the present application is along the Figure 2 The cross-sectional view obtained by cutting along the CC direction is shown in Figure 3and Figure 4 The wiring pipe 11 includes 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 to the inner circle of the annular sealing plate 115, and the end of the outer pipe 113 is connected to the outer circle of the annular sealing plate 115, so that a watertight compartment can be enclosed by the outer pipe 113, the inner pipe 114 and the annular sealing plate 115. The double-layer design makes it difficult for water to enter the inner pipe 114 through which the power transmission cable 4 is passed, so that the power transmission cable 4 is not easily damaged by water. In addition, a support ring (not shown in the figure) can be arranged in the watertight compartment, so that it can be connected to the outer wall of the inner pipe 114 via the inner circle of the support ring, and connected to the inner wall of the outer pipe 113 via the outer circle of the support ring, so that the watertight compartment can be divided into multiple sections, thereby improving the anti-sinking effect.

[0035] The flexible sealing unit 13 can be specifically configured to include a flexible sealing tube 131 (which can be made of rubber material) and a connecting pressure ring 132. The ends of both ends of the flexible sealing tube 131 are provided with a crimping flange 1311. The connecting pressure ring 132 is formed with a pipe penetration hole suitable for the flexible sealing tube 131 to pass through and a pressure ring through hole suitable for the bolt 5 to pass through. The crimping flange 1311 is formed with a flange through hole matching the pressure ring through hole. A pipe flange 111 is also formed at the end of the wiring pipe 11. The pipe flange 111 is provided with a flange through hole matching the pressure ring through hole. The bolt 5 can pass through the pressure ring through hole, the flange through hole and the flange through hole in sequence to connect with the nut to realize the connection between the flexible sealing tube 131 and the wiring pipe 11, so that a flexible sealing connection between adjacent wiring pipes 11 can be realized through the flexible sealing tube 131.

[0036] It can be understood that the floating component 1 also includes an anti-zipper 14 and an anti-collision guard ring 15. The anti-zipper 14 is connected between the ends of two adjacent wiring tubes 11, and the anti-zipper 14 should be configured so that when it is pulled in a tensioned state, the flexible sealing tube 131 is in a normal or compressed state, so that the anti-zipper 14 can prevent the two adjacent wiring tubes 11 from being affected by waves, resulting in a large distance between the two adjacent wiring tubes 11, causing the flexible sealing tube 131 to be broken.

[0037] Figure 5 yes Figure 1 For the enlarged view of area A, see Figure 4 and Figure 5The anti-collision guard ring 15 is arranged at the end of each wiring tube 11, and the anti-collision guard ring 15 includes a guard ring flange 151, a protective support plate 152 and an anti-collision ring 153. A plurality of protective support plates 152 are connected to the anti-collision ring 153 at equal intervals in the circumferential direction, and the other end of each protective support plate 152 is connected to the guard ring flange 151; the anti-collision guard ring 15 is connected to the pipeline flange 111 via the guard ring flange 151, and the guard ring flange 151 is abutted and clamped between the connecting pressure ring 132 and the pipeline flange 111, and the crimping flange 1311 is abutted and clamped between the connecting pressure ring 132 and the guard ring flange 151. Arranging the anti-collision guard ring 15 at the end of the wiring tube 11 can prevent the flexible sealing tube 131 from being crushed due to the small distance between the two adjacent wiring tubes 11 due to the influence of water waves. In addition, it can be understood that a clearance opening 1531 suitable for the flexible sealing tube 131 to pass through can be provided on the anti-collision ring 153, so that when adjacent wiring tubes 11 are stacked together, the deformation of the flexible sealing tube 131 and the power transmission cable 4 inserted therein will not be too large, thereby making it possible for the flexible sealing tube 131 and the power transmission cable 4 inserted therein to be less easily damaged.

[0038] See also Figure 1 and Figure 3 A water outlet bent portion 112 is also formed on the wiring tube 11. When the wiring tube 11 is placed in water, the water outlet bent portion 112 can float on the water surface. A wire passing opening suitable for the transmission cable 4 to pass through is provided at the water outlet bent portion 112. The transmission cable 4 can pass through the wire passing opening to be connected to the solar panel 3, and the wire passing opening can be above the horizontal plane, so that water is not easy to enter the wiring tube 11 from the wire passing opening, thereby making it difficult for the transmission cable 4 to be damaged by water.

[0039] See also Figure 1 and Figure 6 Each splicing frame 12 can be configured to include a receiving section 121 and a connecting section 122. A connecting section 122 is provided at each end of the receiving section 121 to connect to the wiring tube 11 via the connecting section 122. The two connecting sections 122 between adjacent splicing frames 12 are hinged so that one of the adjacent splicing frames 12 can rotate around the axis of the connecting section 122 in the other.

[0040] Specifically, adjacent splicing frames 12 can be connected by connecting buckles 16, and each connecting segment 122 is provided with a small diameter segment to form a limiting groove at the small diameter segment. The connecting buckle 16 includes a pair of connected buckles. It should be noted that in order to cooperate with the flexible sealing unit 13, there is a certain distance between the connecting segments 122 of two adjacent splicing frames 12. Therefore, the pair of buckles can be connected to a connecting rod, and a buckle is hinged at each end of the connecting rod, and then one of the pair of buckles is connected to one of the adjacent connecting segments 122, and the other of the pair of buckles is connected to the adjacent The buckles are connected to the limiting grooves, and the inner diameter of the buckles is larger than the diameter of the small diameter section and smaller than the diameter of the connecting section 122 (that is, the diameter of the large diameter section outside the small diameter section on the connecting section 122), so that the adjacent floating frames can generate relative movement along the axial direction of the connecting section 122, so as to better achieve the following movement with the waves, and the above-mentioned connection method can realize the overlap between two adjacent splicing frames 12, so as to facilitate the pre-installation of the splicing frames 12, thereby facilitating the on-site installation of the floating photovoltaic bracket.

[0041] The floating photovoltaic bracket in the above technical solution, the second aspect of the present application provides a floating photovoltaic bracket installation method, which comprises the following steps: Pre-installation steps: In the installation workshop, two adjacent wiring tubes 11 are connected via a flexible sealing unit 13. After the connection is completed, the transmission cable 4 is inserted into the whole formed by the wiring tube 11 and the flexible sealing unit 13, and then the adjacent wiring tubes 11 are stacked together for loading, and the splicing frame 12, the connecting bracket 2 and the solar cell panel 3 are loaded.

[0042] On-site installation steps: After the transport vehicle arrives at the site, the wiring pipe 11 and the flexible sealing unit 13 are connected as a whole, the splicing frame 12 and the connecting bracket 2 are unloaded, and then the wiring pipe 11 and the flexible sealing unit 13 are unfolded. The splicing frame 12 and the wiring pipe 11 are connected in sequence to form a floating frame, and the connecting bracket 2 is installed on the floating frame, and the solar panel 3 is installed on the connecting bracket 2. Then the floating frame with the solar panel 3 installed is placed into the water.

[0043] Anchoring steps: Set up an anchor seat on the shore and use a cable to connect the floating frame to the anchor seat.

[0044] A plurality of wiring tubes 11 are connected to form a whole through a flexible sealing unit 13 in a pre-installed form, and the whole formed by the wiring tubes 11 and the flexible sealing unit 13 can be folded for easy loading and transportation. After being transported to the site, the whole formed by the wiring tubes 11 and the flexible sealing unit 13 can be unfolded and installed, thereby greatly facilitating on-site installation.

[0045] The working principle of the floating photovoltaic support in this application is as follows: Directly using the wiring tube 11 as a part of the floating component 1 can make the overall structure of the floating photovoltaic support simpler. The two adjacent wiring tubes 11 are connected by the flexible sealing unit 13, so that when the floating component 1 is hit by waves, the wiring tubes 11 connected in series can rise and fall with the waves, thereby effectively avoiding the problem of setting the wiring tube 11 as a whole, and the waves covering the wiring tube 11 when passing through the wiring tube 11 and hitting the solar panel 3 to cause damage to the device and circuit. In addition, the flexible sealing unit 13 can be bent until the ports of the two connecting ends are flush, so the transmission cable 4 can be first passed through the wiring tube 11, and it is convenient to stack the adjacent wiring tubes 11 for loading and transportation. After arriving at the construction site, it is only necessary to unfold the wiring tube 11 and the flexible sealing unit 13 to form a whole, which can greatly reduce the time of on-site installation and make on-site installation more convenient.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
