[0003] Solar-fishery complementary photovoltaic (SPCP) refers to a sustainable development approach that combines photovoltaic power generation with fisheries. By installing photovoltaic panels in fishing waters, solar energy is utilized to generate electricity while preserving the economic value and ecological environment of fisheries. This method enables comprehensive resource utilization in fishing waters, improves energy efficiency, promotes the adoption of renewable energy, and does not negatively impact the aquatic ecosystem or fisheries production. In solar-fishery complementary projects, photovoltaic panels are typically fixed using clamps, with construction relying heavily on on-site installation, sometimes even requiring work on water. The installation process is complex, demanding high stability and precise clamp installation. Furthermore, subsequent maintenance and disassembly are difficult, requiring specialized tools and preventing rapid installation and removal. Summary of the Invention

The cylindrical section is configured to pass through the guide section and form a guiding engagement with the guide section. When the installation assembly is in the unfolded state, the second support arm cooperates with the stop structure to form an axial limit. When the installation assembly is in the retracted state, the bottom of the first connecting section abuts against the third connecting section.

[0008] Furthermore, a connecting part is provided at the end of the cylindrical segment away from the second connecting segment, and the connecting part is detachably connected to the first connecting segment.

[0009] Furthermore, the inner wall of the first connecting section is provided with an annular groove, and the second end of the first cylinder is provided with an annular protrusion that matches the annular groove, with the annular protrusion and the annular groove rotating together.

[0010] Furthermore, multiple fixing structures are provided on the inner wall of the pre-embedded structure, forming a stop structure. The multiple fixing structures are spaced apart along the circumference of the pre-embedded structure in the installation cavity. The multiple fixing structures are located on the outer periphery of the outer cylinder. There are multiple support arms, and each support arm is corresponding to one of the multiple fixing structures. When the installation component is in the unfolded state, each support arm engages with the corresponding fixing structure to form a limit in the direction of the installation component's release.

[0011] Furthermore, the outer cylinder is provided with multiple through slots, and each through slot corresponds to a multiple support arm. Each fixing structure has an opening and a receiving cavity communicating with the opening. A slot is provided in the receiving cavity. Multiple openings correspond to multiple through slots. When the installation component is in the unfolded state, the second support arm extends out from the through slot and enters the receiving cavity through the opening and engages with the slot.

[0012] Furthermore, the cavity is provided with multiple slots, which are arranged vertically.

[0013] Furthermore, the photovoltaic installation structure also includes a seismic-resistant structure, which forms the bottom of the installation cavity, with the outer cylinder placed on top of the seismic-resistant structure.

Detailed Implementation

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Referring to Figures 1 to 4, this application provides a photovoltaic installation structure, which includes: a pre-embedded structure 10 having an installation cavity 11 and a stop structure; and an installation assembly 20, the installation assembly 20 including a drive structure 30 and a support arm 40. The drive structure 30 is used to drive the support arm 40 to unfold or retract, so that the installation assembly 20 can switch between an unfolded state and a retracted state. When the support arm 40 is unfolded, the support arm 40 can cooperate with the stop structure to connect the installation assembly 20 to the pre-embedded structure 10. When the support arm 40 is retracted, the installation assembly 20 can detach from the pre-embedded structure 10. The installation assembly 20 also includes an outer cylinder 50 and an adjustment structure 60. The outer cylinder 50 is partially located within the installation cavity 11. The adjustment structure 60 and the drive structure 30 are both installed within the outer cylinder 50. The support arm 40 is connected between the adjusting structure 60 and the driving structure 30, and the driving structure 30 can move relative to the outer cylinder 50 towards or away from the adjusting structure 60 to allow the support arm 40 to unfold or retract. The adjusting structure 60 is fixedly installed on the inner wall of the outer cylinder 50. The driving structure 30 includes a first cylinder 31 and a second cylinder 32. The first end of the first cylinder 31 is threadedly engaged with the inner wall of the outer cylinder 50, and the second end of the first cylinder 31 is rotatably engaged with the first end of the second cylinder 32. The second end of the first cylinder 31 and the first end of the second cylinder 32 form an axial limit. The second end of the second cylinder 32 is located below the adjusting structure 60. The first cylinder 31 can move relative to the outer cylinder 50 in a vertical direction to drive the second cylinder 32 to move towards or away from the adjusting structure 60.

[0029] In this embodiment, the mounting component 20 is used to connect with the photovoltaic bracket, on which photovoltaic panels are installed to realize photovoltaic power generation. The outer cylinder 50 provides installation space for the drive structure 30 and the adjustment structure 60. The drive structure 30 is installed inside the outer cylinder 50 and can move relative to the outer cylinder 50 towards or away from the adjustment structure 60, so that the support arm 40 can be extended or retracted, thereby allowing the mounting component 20 to switch between the extended state and the retracted state, realizing a detachable connection between the mounting component 20 and the pre-embedded structure 10. The first end of the first cylinder 31 is threaded into the inner wall of the outer cylinder 50 to install the drive structure 30 inside the outer cylinder 50. Since the second end of the first cylinder 31 is rotatably engaged with the first end of the second cylinder 32 and forms an axial limit with the first end of the second cylinder 32, the second cylinder 32 does not rotate during the rotation of the first cylinder 31. Rotating the first cylinder 31 causes the first cylinder 31 to move vertically relative to the outer cylinder 50. At this time, the first cylinder 31 can carry the second cylinder 32 to move vertically relative to the outer cylinder 50, thereby causing the second end of the second cylinder 32 to move towards or away from the adjustment structure 60, thus realizing the unfolding or retraction of the support arm 40.

[0030] During installation, the drive structure 30 drives the support arm 40 to unfold. At this time, the mounting component 20 is in the unfolded state, and the support arm 40 cooperates with the stop structure to connect the mounting component 20 with the pre-embedded structure 10. When maintenance is required, the drive structure 30 drives the support arm 40 to retract, and the mounting component 20 changes from the unfolded state to the retracted state, disengaging the mounting component 20 from the pre-embedded structure 10. This design eliminates the need for special tools during the assembly and disassembly of the pre-embedded structure 10 and the mounting component 20, making the installation and disassembly process more convenient and improving efficiency.

[0031] In addition, when the photovoltaic installation structure of this application is applied to waterborne photovoltaic installation, the pre-embedded structure 10 is installed in the concrete structure of the installation location on the water. The installation component 20 can be pre-installed on the shore in advance, and then the installed installation component 20 is transported to the installation location by boat. The installation component 20 can be connected to the pre-embedded structure 10 on the deck, which can reduce the amount of waterborne installation work and improve installation efficiency.

[0032] In one embodiment, there are multiple support arms 40, which are arranged at circumferential intervals along the mounting assembly 20.

[0033] Referring to Figures 1 to 4, in one embodiment of this application, the support arm 40 includes a first arm 41 and a second arm 42. The first end of the first arm 41 is hinged to the adjustment structure 60, the second end of the first arm 41 is hinged to the middle of the second arm 42, and the first end of the second arm 42 is hinged to the second end of the second cylinder 32. When the mounting assembly 20 is in the unfolded state, the second end of the second arm 42 extends out of the outer cylinder 50. When the mounting assembly 20 is in the retracted state, the second end of the second arm 42 retracts into the outer cylinder 50.

[0034] In this embodiment, when maintenance is required, the first cylinder 31 is rotated, causing the first cylinder 31 to move the second end of the second cylinder 32 away from the adjusting structure 60. At this time, the first support arm 41 rotates towards the central axis of the outer cylinder 50, and drives the second support arm 42 to rotate towards the central axis of the outer cylinder 50. The second end of the second support arm 42 retracts into the outer cylinder 50. Thus, during the disengagement of the mounting assembly 20 from the embedded structure 10, the second end of the second support arm 42 will not interfere with the inner wall of the embedded structure 10. During installation, the first cylinder 31 is rotated, causing the first cylinder 31 to move the second end of the second cylinder 32 towards the adjusting structure 60. At this time, the first support arm 41 rotates away from the central axis of the outer cylinder 50, and drives the second support arm 42 to rotate away from the central axis of the outer cylinder 50. The second end of the second support arm 42 extends out of the outer cylinder 50 and cooperates with the stop structure to achieve the connection between the mounting assembly 20 and the embedded structure 10.

[0035] Referring to Figures 1 to 4, in one embodiment of this application, the second cylinder 32 includes a first connecting section 321, a cylindrical section 322, and a second connecting section 323. The adjusting structure 60 includes a third connecting section 61 and a guide section 62 disposed on the side of the third connecting section 61 away from the first cylinder 31. The third connecting section 61 is fixedly connected to the inner wall of the outer cylinder 50. The guide section 62 extends in a direction away from the first cylinder 31. The cylindrical section 322 is configured to pass through the guide section 62 and form a guiding engagement with the guide section 62. When the mounting assembly 20 is in the unfolded state, the second support arm 42 cooperates with the stop structure to form an axial limit. When the mounting assembly 20 is in the retracted state, the bottom of the first connecting section 321 abuts against the third connecting section 61.

[0036] In this embodiment, the cylindrical segment 322 passes through the guide segment 62 and forms a guiding engagement with the guide segment 62. This prevents the cylindrical segment 322 from swaying radially in the outer cylinder 50 as the second cylinder 32 moves towards or away from the adjusting structure 60 under the influence of the first cylinder 31, thus improving structural stability. When the mounting assembly 20 is in the extended state, the second support arm 42 engages with the stop structure to form an axial limit. At this time, the first cylinder 31 cannot move vertically relative to the outer cylinder 50, thus connecting the mounting assembly 20 to the embedded structure 10. When the mounting assembly 20 is in the retracted state, the bottom of the first connecting segment 321 abuts against the third connecting segment 61. At this time, the third connecting segment 61 stops the first connecting segment 321, preventing the first cylinder 31 from continuing to move towards the adjusting structure 60 relative to the outer cylinder 50, and the support arm 40 retracts into place.

[0037] Referring to Figures 1 to 4, in one embodiment of this application, a connecting portion 324 is provided at the end of the cylindrical segment 322 away from the second connecting segment 323, and the connecting portion 324 is detachably connected to the first connecting segment 321.

[0038] With the above settings, a detachable connection between the cylindrical segment 322 and the first connecting segment 321 can be achieved.

[0039] In one embodiment, the cylindrical segment 322 and the first connecting segment 321 are detachably connected by bolts.

[0040] Referring to Figures 1 to 4, in one embodiment of this application, the inner wall of the first connecting section 321 is provided with an annular groove 325, and the second end of the first cylinder 31 is provided with an annular protrusion 311 adapted to the annular groove 325, and the annular protrusion 311 and the annular groove 325 are rotatably engaged.

[0041] With the above settings, the connection between the first cylinder 31 and the second cylinder 32 can be achieved, and the first cylinder 31 can rotate relative to the second cylinder 32.

[0042] Referring to Figures 1 to 4, in one embodiment of this application, a plurality of fixing structures 70 are provided on the inner wall of the pre-embedded structure 10. The plurality of fixing structures 70 form a stop structure. The plurality of fixing structures 70 are arranged at intervals along the circumference of the pre-embedded structure 10 in the mounting cavity 11. The plurality of fixing structures 70 are located on the outer periphery of the outer cylinder 50. There are a plurality of support arms 40, and the plurality of support arms 40 are arranged in a one-to-one correspondence with the plurality of fixing structures 70. When the mounting assembly 20 is in the unfolded state, each support arm 40 engages with the corresponding fixing structure 70 to form a limit in the release direction of the mounting assembly 20.

[0043] With the above settings, the connection between the installation component 20 and the embedded structure 10 can be achieved.

[0044] Referring to Figures 1 to 4, in one embodiment of this application, the outer cylinder 50 is provided with multiple through slots, and the multiple through slots are provided one-to-one with multiple support arms 40. Each fixing structure 70 has an opening and a receiving cavity communicating with the opening. A slot is provided in the receiving cavity. The multiple openings are provided one-to-one with the multiple through slots. When the mounting assembly 20 is in the unfolded state, the second support arm 42 extends out from the through slot and enters the receiving cavity through the opening and engages with the slot.

[0045] In this embodiment, when the support arm 40 is unfolded, the second end of the second arm 42 extends out of the outer cylinder 50 through the through groove, and then enters the receiving cavity through the opening and engages with the slot provided in the receiving cavity, thereby realizing the connection between the installation structure and the pre-embedded structure 10.

[0046] Referring to Figures 1 to 4, in one embodiment of this application, a plurality of slots are provided in the receiving cavity, and the plurality of slots are arranged in a vertical direction.

[0047] In this embodiment, the second end of the support arm 40 engages with slots at different positions, enabling the vertical adjustment of the position of the drive structure 30 relative to the outer cylinder 50. This allows for the adjustment of the length of the first cylinder 31 protruding from the outer cylinder 50. Since the end of the first cylinder 31 away from the second cylinder 32 is used to connect to the photovoltaic bracket, the height of the photovoltaic bracket can be adjusted through the above-mentioned arrangement.

[0048] It should be noted that when using existing installation methods, the pile driving height of concrete piles may vary, resulting in differences in the height at which workers install the clamps. However, when using the photovoltaic installation structure of this application, the height of the photovoltaic bracket can be adjusted, thereby ensuring a uniform overall installation height.

[0049] Referring to Figures 1 to 4, in one embodiment of this application, the photovoltaic mounting structure further includes an anti-seismic structure 80, which forms the bottom of the mounting cavity 11, and the outer cylinder 50 is placed on top of the anti-seismic structure 80.

[0050] In this embodiment, the earthquake-resistant structure 80 can buffer the mounting assembly 20 in the vertical direction, thereby improving the earthquake resistance of the mounting assembly 20.

[0051] Referring to Figures 1 to 4, in one embodiment of this application, the seismic-resistant structure 80 includes a first mounting body 81 and a first wave-shaped structure 82 disposed within the first mounting body 81. The crests of the first wave-shaped structure 82 abut against the top of the first mounting body 81, and the troughs of the first wave-shaped structure 82 abut against the bottom of the first mounting body 81, so that the first wave-shaped structure 82 can form multiple triangular support structures with the first mounting body 81.

[0052] In this embodiment, the crest of the first wave-shaped structure 82 can form multiple triangular support structures with the top wall of the first mounting body 81, and the trough of the first wave-shaped structure 82 can form multiple triangular support structures with the bottom wall of the first mounting body 81. Since triangles have good stability, the above-mentioned arrangement can enhance the seismic performance of the photovoltaic mounting structure.

[0053] In one embodiment of this application, the first corrugated structure 82 is made of glass fiber. Glass fiber material has the characteristics of high strength and corrosion resistance, thus giving the first corrugated structure 82 high strength and corrosion resistance, thereby improving the service life of the seismic structure 80.

[0054] Referring to Figures 1 to 4, in one embodiment of this application, the photovoltaic installation structure further includes a second installation body 91. The second installation body 91 forms a stop structure and forms the top of the installation cavity 11. When the installation assembly 20 is in the unfolded state, the second support arm 42 abuts against the bottom of the second installation body 91, and the bottom of the outer cylinder 50 abuts against the anti-vibration structure 80.

[0055] In this embodiment, the second mounting body 91 forms a stop structure. When the mounting component 20 is in the unfolded state, the second support arm 42 abuts against the bottom of the second mounting body 91, limiting the release direction of the mounting component 20 and realizing the connection between the mounting component 20 and the pre-embedded structure 10. In addition, when the second support arm 42 abuts against the bottom of the second mounting body 91, the mounting component 20 cannot move vertically relative to the outer cylinder 50. If the first cylinder 31 is rotated (rotated in a direction that allows the second end of the second cylinder 32 to move closer to the adjustment structure 60), the outer cylinder 50 moves relative to the first cylinder 31 towards the earthquake-resistant structure 80 and abuts against the earthquake-resistant structure 80, thereby improving the connection stability between the mounting component 20 and the pre-embedded structure 10.

[0056] Referring to Figures 1 to 5, the photovoltaic installation structure also includes a ring-shaped installation structure 100 and multiple vibration damping support structures 200. The multiple vibration damping support structures 200 are arranged at intervals along the circumference of the ring-shaped installation structure 100. One end of each vibration damping support structure 200 is connected to the second installation body 91, and the other end of each vibration damping support structure 200 is connected to the ring-shaped installation structure 100. The outer cylinder 50 is configured to pass through the ring-shaped installation structure 100.

[0057] In this embodiment, the damping support structure 200 is a prior art BRB yield restraint brace (a type of seismic reinforcement damper), and the second mounting body 91 is a frame structure. The BRB yield restraint brace is connected between the ring mounting structure 100 and the second mounting body 91 as a support member of the second mounting body 91. The BRB yield restraint brace can withstand horizontal and vertical loads, thereby improving the seismic performance of the second mounting body 91 and improving the overall stability of the photovoltaic mounting structure.

[0058] Referring to Figures 1 to 4, in one embodiment of this application, a second wave-shaped structure 92 is provided inside the second mounting body 91. The crest of the second wave-shaped structure 92 abuts against the top of the second mounting body 91, and the trough of the second wave-shaped structure 92 abuts against the bottom of the second mounting body 91, so that the second wave-shaped structure 92 can form multiple triangular support structures with the second mounting body 91.

[0059] In this embodiment, the crests of the second wave-shaped structure 92 can form multiple triangular support structures with the top wall of the second mounting body 91, and the troughs of the second wave-shaped structure 92 can form multiple triangular support structures with the bottom wall of the second mounting body 91. Since triangles have good stability, the above-mentioned arrangement can enhance the seismic performance of the photovoltaic mounting structure.

[0060] In one embodiment of this application, the second corrugated structure 92 is made of glass fiber. Glass fiber material has the characteristics of high strength and corrosion resistance, thus giving the second corrugated structure 92 high strength and corrosion resistance, thereby improving the service life of the second corrugated structure 92.

[0061] Referring to Figures 1 to 4 and Figure 6, the photovoltaic installation structure also includes a ring-shaped installation structure 100 and multiple vibration damping support structures 200. The multiple vibration damping support structures 200 are arranged at intervals along the circumference of the ring-shaped installation structure 100. One end of each vibration damping support structure 200 is connected to the second installation body 91, and the other end of each vibration damping support structure 200 is connected to the ring-shaped installation structure 100. The outer cylinder 50 is configured to pass through the ring-shaped installation structure 100.

[0062] In this embodiment, the damping support structure 200 is a prior art BRB yield restraint brace (a type of seismic reinforcement damper), and the second mounting body 91 is a frame structure. The BRB yield restraint brace is connected between the ring mounting structure 100 and the second mounting body 91 as a support member of the second mounting body 91. The BRB yield restraint brace can withstand horizontal and vertical loads, which can enhance the seismic resistance of the photovoltaic mounting structure. At the same time, the second wave-shaped structure 92 and the second mounting body 91 form multiple triangular support structures. Since triangles have good stability, they can further improve the seismic performance of the photovoltaic mounting structure.

[0063] In one embodiment of this application, the pre-embedded structure 10 also has an installation channel, which is connected to the installation cavity 11. A portion of the outer cylinder 50 enters the installation cavity 11 through the installation channel, and the installation channel is adapted to the outer wall of the outer cylinder 50.

[0064] The above settings facilitate the installation of the outer cylinder 50.

[0065] In one embodiment, a seal is provided at the entrance end of the installation channel. When the outer cylinder 50 partially enters the installation channel, the outer wall of the outer cylinder 50 is squeezed with the seal to form a sealing fit, so that the inside of the installation channel is in a closed state, thereby reducing the entry of seawater vapor, thereby reducing the corrosion of the internal structure by seawater and improving the corrosion resistance of the photovoltaic installation structure.

[0066] In one embodiment, the seal is a rubber ring, which can reduce vibration in the radial direction of the outer cylinder 50.

[0067] According to another aspect of this application, a photovoltaic power station is also provided, comprising: a concrete structure, an embedded structure 10 having one end away from the mounting component 20 installed within the concrete structure, a photovoltaic support having a plurality of photovoltaic panels mounted on the photovoltaic support; and the aforementioned photovoltaic mounting structure having one end of the mounting component 20 facing away from the embedded structure 10 connected to the photovoltaic support.

[0068] In this embodiment, the photovoltaic installation structure of the photovoltaic power station has all the technical solutions and effects of the aforementioned photovoltaic installation structure, which will not be repeated here.

[0069] As can be seen from the above description, the embodiments of this application achieve the following technical effects: A pre-embedded structure and an installation component are provided. The pre-embedded structure has an installation cavity and a stop structure. The installation component includes a drive structure and a support arm. The drive structure drives the support arm to unfold, placing the installation component in an unfolded state. At this time, the support arm cooperates with the stop structure to connect the installation component to the pre-embedded structure.
