[0032] In related technologies, offshore photovoltaic (PV) systems typically include support units and PV modules. The support unit comprises connected pile foundations and a superstructure, which is used to install the PV panels, thus supporting and securing the PV modules in the ocean. Currently, the pile foundations are installed at predetermined locations in the ocean using methods such as hoisting, and then the superstructure is hoisted and fixed to the pile foundations. After the initial installation of the support unit, further detailed operations are required, such as releasing the hoisting hooks, adding PV panels, and performing anti-corrosion work. This requires personnel to travel between the sea surface and the top of the pile foundations. Existing technologies typically use rope hoisting for personnel movement, but this method has low safety and limited working space for personnel at the top of the pile foundations.
[0033] Based on this, the present disclosure provides a ring-shaped operation device for the construction of offshore photovoltaic support units, such as... Figure 1 As shown, combined with Figures 2 to 3 The device includes: a main body, a support assembly 20, a lifting assembly 30, and a control assembly 40.
[0034] The main body includes a first annular component 101 and an annular work platform 103. The first annular component 101 is sleeved on the outer wall of the pile foundation 100 and is formed by a plurality of first rods 111, each of which is arranged along a direction parallel to the axis of the pile foundation 100. The first annular component 101 is slidably connected to the pile foundation 100. The annular work platform 103 is connected to the bottom end of the first annular component 101, and the surface of the annular work platform 103 is perpendicular to the axis of the pile foundation 100. The support component 20 includes a first suspension member. 21. The first suspension member 21 is symmetrically sleeved on the chord members 300 located on both sides of the pile foundation 100; the lifting assembly 30 includes a sliding system 31, a second suspension member 32 and a connecting part 33 connected in sequence. The sliding system 31 is connected to the first suspension member 21, and one end of the connecting part 33 is fixedly connected to the top end of the first annular assembly 101; the control assembly 40 is located on the outside of the first annular assembly 101. The control assembly 40 is connected to the lifting assembly 30 and is used to drive the lifting assembly 30 to move the main body along the axis parallel to the pile foundation 100.
[0035] The ring-shaped working device provided in this disclosure, through the sliding connection between the first ring component 101 and the pile foundation 100, enables the device to move between the top of the pile foundation 100 and the sea level, providing a support platform for workers. The main body of the device includes a ring-shaped working platform 103, which can increase the working space for workers and facilitate improved construction efficiency. Through the interconnection and cooperation of the main body, support component 20, lifting component 30 and control component 40, the device can reliably move back and forth between the top of the pile foundation 100 and the sea level. The connection stability of each component is high, the overall safety of the device is high, and the safety of workers during the construction process is guaranteed.
[0036] In this disclosure, the ring-shaped working device is connected to the pile foundation 100 of the offshore photovoltaic system. One end of the pile foundation 100 is fixed to the seabed, and the other end extends above the sea level. The pile foundation 100 and the upper support structure 200 form a support unit. The upper support structure 200 includes multiple connection nodes, and multiple chord members 300 are connected to the multiple connection nodes to form the upper support structure 200. The top of the pile foundation 100 is welded to one of the connection nodes in the upper support structure 200, forming a connection between the pile foundation 100 and the upper support structure 200. In this disclosure, the top of the pile foundation 100 refers to the end of the pile foundation 100 extending above the sea level, and the bottom of the pile foundation 100 refers to the end of the pile foundation 100 located in the sea and fixed to the seabed. The top and bottom are relative terms, and they will change depending on the position or state of the pile foundation 100. The way the top and bottom are described does not limit the structure and position of the pile foundation 100 or the device.
[0037] In this disclosure, the work on the support unit includes manual operations such as laying photovoltaic panels on the upper support structure 200, performing anti-corrosion work on the top of the pile foundation 100, and removing the hoisting hook. The environment used by the device in this disclosure includes, but is not limited to, the above-mentioned environment. This disclosure does not make any specific limitations.
[0038] The following will describe in detail the various parts of the ring-shaped working device for the construction of offshore photovoltaic support units provided in the embodiments of this disclosure, with reference to the accompanying drawings:
[0039] In the embodiments provided in this disclosure, such as Figures 1 to 3 As shown, the device includes a main body that is fitted onto the outside of the pile foundation 100. The main body and the pile foundation 100 can move relative to each other. The main body is a symmetrical component, and the axis of symmetry of the main body is the axis of the pile foundation 100, so as to ensure the stability of the main body and prevent the main body from tilting or getting stuck when it is displaced.
[0040] The main body includes a first annular component 101, a second annular component 102, and an annular worktable 103.
[0041] The first annular component 101 is sleeved on the outer wall of the pile foundation 100. The first annular component 101 is formed by multiple first rods 111. Each first rod 111 is arranged along the axis parallel to the pile foundation 100. By setting the first annular component 101 in the device, the positional relationship between the pile foundation 100 and the device can be realized, providing a structural basis for the movement of the device on the pile foundation 100.
[0042] The first annular component 101 is slidably connected to the pile foundation 100. A roller structure 121 is provided on the inner side of the first annular component 101. One side of the roller structure 121 is fixedly connected to the first annular component 101, and the other side of the roller structure 121 is in rolling contact with the outer wall of the pile foundation 100. The roller structure 121 may include a fixed shaft and a roller. The fixed shaft is fixedly connected to one or more first rods 111 facing the pile foundation 100. The roller is connected to the fixed shaft and can rotate on the fixed shaft. The roller contacts the outer wall of the pile foundation 100. The movement of the first annular component drives the roller structure 121 to roll on the outer wall of the pile foundation 100. The roller structure 121 ensures the integrity of the anti-corrosion layer on the outer wall of the pile foundation 100 and prevents damage to the anti-corrosion layer caused by relative movement between the first annular component 101 and the pile foundation 100.
[0043] The roller structure 121 can be disposed at the top of the first annular component 101, or at the bottom of the first annular component 101, or simultaneously at both the top and bottom of the first annular component. The number of roller structures 121 can be one or more. When there are multiple roller structures 121, they are evenly distributed around the circumference of the pile foundation 100 and are located in the same plane. Furthermore, to ensure the stability of the first annular component 101 during movement and to prevent tilting or jamming of the main body during movement, roller structures 121 can be simultaneously disposed at both the top and bottom of the first annular component 101. For example, when there are eight roller structures 121, four roller structures 121 are disposed at the top of the first annular component 101, and the other four roller structures 121 are disposed at the bottom of the first annular component 101, with the eight roller components arranged symmetrically.
[0044] A circular work platform 103 is connected between the first circular assembly 101 and the second circular assembly 102, and is fixedly connected to the bottom ends of multiple first rods 111 and multiple second rods 112. The circular work platform 103 can be circular or near-circular, and its surface is perpendicular to the axis of the pile foundation 100 to ensure it provides support for workers. By connecting the first circular assembly 101 and the second circular assembly 102 with the circular work platform 103, workers can operate within the annular space formed by the first circular assembly 101, the second circular assembly 102, and the circular work platform 103, increasing their operating space and improving construction efficiency.
[0045] The annular work platform 103 can be a solid structure or a hollow structure. For example, when the annular work platform 103 is a hollow structure, it can be composed of multiple rods radiating away from the pile foundation 100 as the center and multiple annular rods centered on the pile foundation 100. This hollow structure is more suitable for offshore operating environments.
[0046] The second annular component 102 is concentrically arranged with the first annular component 101, and is connected to the edge of the annular work platform 103 along an axis parallel to the pile foundation 100. The second annular component 102 is formed by a plurality of second rods 112, the axis of each second rod 112 being parallel to the axis of the pile foundation 100. The lengths of the plurality of second rods 112 are equal, and the length of a second rod 112 may be greater than or equal to the length of a first rod 111. For example, the length of a second rod 112 may be greater than the length of a first rod 111, ensuring that the second annular component 102 formed by the plurality of second rods 112 has sufficient safety height to ensure the safety of workers. Furthermore, the distance between two adjacent second rods 112 needs to be less than a preset distance, where the preset distance refers to the average height of a normal adult, further improving the safety of the second annular component 102.
[0047] The second annular assembly 102 also includes a hinge structure and a safety door. The safety door is composed of a portion of the second rod 112 and can rotate around the hinge structure. Operators can enter and exit the annular work device by rotating the safety door. Furthermore, a latch can be provided on the edge of the safety door. After the operator enters the device, the safety door can be latched onto the second annular assembly 102 to secure the safety door and provide safety for the operator.
[0048] In the embodiments provided in this disclosure, such as Figures 1 to 3 As shown, the device includes a support assembly 20, which includes a first suspension member 21. The first suspension member 21 is symmetrically sleeved on the chord members 300 located on both sides of the pile foundation 100.
[0049] In this disclosure, the chord members 300 of the upper support structure 200 may include upper chord members 300 and lower chord members 300. Multiple upper chord members 300 can be used to form a support surface for the photovoltaic module, while multiple lower chord members 300 form the lower structure of the upper support structure 200. The distance between the lower chord members 300 and the pile foundation 100 is less than the distance between the upper chord members 300 and the pile foundation 100. To facilitate the installation of the main body of the ring-shaped working device, improve structural strength, and save costs, the first suspension member 21 is typically connected to the lower chord members 300 of the upper support structure 200.
[0050] The first suspension member 21 may include at least two lifting rings. The first suspension member 21 is sleeved on two symmetrically arranged lower chords 300. The first suspension member 21 may also include a connector connected to the lifting rings. The connector can be connected to the lifting assembly 30. The first suspension member 21 can realize the effective connection between the lifting assembly 30 and the upper support structure 200. The upper support structure 200 can provide effective tension for the device and ensure the structural stability of the device.
[0051] The support component 20 can be an axisymmetric component, with the axis of symmetry of the support component 20 being the axis of the pile foundation 100. The support component 20 cooperates with the main body and can provide stable support for the main body to ensure the stability of the device and prevent the device from tilting or jamming when displacement occurs.
[0052] In the embodiments provided in this disclosure, such as Figures 1 to 3 As shown, the device includes a lifting assembly 30, which includes a sliding system 31, a second suspension member 32, and a connecting part 33 connected in sequence. The sliding system 31 is connected to the first suspension member 21, and one end of the connecting part 33 is fixedly connected to the top end of the first annular assembly 101.
[0053] In some embodiments, the device further includes a safety protection component 50, which is symmetrically disposed on the outer side of the first annular component 101 and connects the sliding system 31 and the second suspension component 32.
[0054] When the operating speed of the main body exceeds the preset speed, or the angle between the axis of the annular work platform 103 and the pile foundation 100 exceeds the preset angle, or when both the operating speed of the main body exceeds the preset speed and the angle between the axis of the annular work platform 103 and the pile foundation 100 exceeds the preset angle, the safety protection component 50 is used to lock the main body to prevent the operator from falling out of the device due to sudden changes in the speed and position of the device, thereby ensuring the safety of the operator.
[0055] The preset speed can refer to the safe operating speed of the device. When the operating speed of the device is less than the preset speed, the stability and safety of the personnel on the device can be guaranteed. This preset speed can be selected or adjusted adaptively according to actual operating needs, and this disclosure does not make specific limitations.
[0056] The preset angle refers to the angle between the surface of the annular workbench 103 and the axis of the pile foundation 100. It represents the maximum angle that ensures the normal operation of the device. This preset angle can be selected and adjusted based on the proportional relationship between the dimensional parameters of each structure within the main body and the dimensional parameters of the pile foundation 100. For example, if the overall size of the main body is large and the length of the pile foundation 100 is the first dimension, then the preset angle can be relatively large. When the device is less than or equal to the preset angle, the device will not jam, and the operator will have stable support. Conversely, if the overall size of the main body is small and the length of the pile foundation 100 is still the first dimension, then the preset angle can be relatively small. When the device is less than or equal to the preset angle, the device will not jam, and the operator will have stable support. Furthermore, the preset angle can be between 10° and 30°.
[0057] The safety protection component 50 can be a safety lock. The control component 40 controls the state of the safety lock. Under the aforementioned locking conditions, the control component can lock the safety lock to prevent danger and improve the safety of the device. Furthermore, the safety protection component 50 can also be manually locked and unlocked according to actual needs. If the aforementioned locking conditions are not met, the safety protection component 50 can be manually started and stopped according to the actual operation of the device to further prevent accidental danger and improve the applicability of the safety protection component 50.
[0058] In some embodiments, the sliding system 31 in the lifting assembly 30 includes a cable 311 and a pulley block 312. The pulleys are fixedly connected to the first suspension member 21. The cable 311 is wound around the pulley block 312 and extends along an axis parallel to the pile foundation 100. One end of the cable 311 is connected to the safety protection assembly 50, and the other end of the cable 311 is connected to the control assembly 40. The extension and retraction of the cable 311 are controlled by the control assembly 40 to lift the main body to different heights.
[0059] The number of pulleys in the pulley block 312 can be matched with the number of lifting rings in the first suspension member 21. For example, the pulleys and lifting rings can have a one-to-one correspondence. In this disclosure, the pulleys can be fixed pulleys, and the cable 311 can change its direction of movement through the fixed pulleys to realize the position adjustment of the main body by the control component 40, so that the main body reaches the preset position of the pile foundation 100.
[0060] The second suspension member 32 is positioned between the sliding system 31 and the connecting part 33. The second suspension member 32 can be a hook or a ring structure. The connecting part 33 can be a rectangular frame structure formed by multiple third rods 331. One short side of the connecting part 33 is connected to the top of the second annular assembly 102, and the other short side is connected to the top of the first annular assembly 101. The second suspension member 32 is connected to the long side of the connecting part 33 away from the annular worktable 103. To ensure connection stability, the second suspension member 32 can be connected at the center line of the connecting part 33. The connecting part 33 enables the connection between the main body and the sliding system 31. During device movement, the control component 40 controls the sliding cable 311 in the sliding system 31. The sliding cable 311 drives the connecting part 33 and the main body to move simultaneously, achieving the lifting and lowering of the device.
[0061] To avoid obstructing the operating space within the main body, the bottom edge of the connecting part 33 can overlap the top ends of the first annular assembly 101 and the second annular assembly 102, and then be connected by welding, screwing, riveting, or bonding. That is, the projection of the connecting part 33 onto the annular worktable 103 is a straight line, maximizing the operating space within the main body. Furthermore, to ensure the reliability of the connection between the connecting part 33 and the main body, welding is typically used to connect the main body and the connecting part 33.
[0062] In this disclosure, the lifting assembly 30 is an axisymmetric assembly, and its axis of symmetry is the axis of the pile foundation 100. The symmetrical structure of the lifting assembly 30 can improve the overall stability of the device.
[0063] In the embodiments provided in this disclosure, the device includes a control component 40, which is disposed outside the first annular component 101. The control component 40 is connected to the lifting component 30 and is used to drive the lifting component 30 to move the main body along an axis parallel to the pile foundation 100.
[0064] The control component 40 may include a control box, allowing operators to remotely control the lifting, stopping, and other operational functions of the device. The control component 40 may also include a control system, which typically includes an operation panel and remote control devices, capable of operation both inside and outside the device to ensure its stability and safety. The control system can be integrated into the control box for easy operator access. Furthermore, the control component 40 includes an automatic braking system, used to stop the device in the event of a malfunction in the control component 40, preventing the malfunction from affecting operator safety.
[0065] It should be noted that the control component 40 also includes other devices or structures such as winches and electric hoists for providing power, as well as other structures or devices necessary to assist the control component 40 in performing control operations. Although these devices are not described in detail in this disclosure, it should be understood that all auxiliary devices of the control component are included in the control component 40.
[0066] In the embodiments provided in this disclosure, the device may further include multiple safety ropes (not shown in the figure), which are suspended on the chord 300. One end of the safety rope has a safety buckle, which can be used to connect the worker. The safety rope provides further protection for the worker, preventing the worker from falling accidentally and ensuring that the worker can be safely suspended in an emergency, thereby improving the safety of the operation.
[0067] In this disclosure, the first rod 111, the second rod 112, and the third rod 331 can all be made of metal, such as copper, aluminum, iron, or steel. To further improve the structural strength of the device, the first rod 111, the second rod 112, and the third rod 331 can all be made of steel and undergo surface anti-corrosion treatment to improve the mechanical strength of the device and increase its service life.
[0068] In the embodiments provided in this disclosure, the first annular component 101 can be designed and adaptively adjusted according to the size and shape of the pile foundation 100; the size parameters of the second annular component 102 and the annular work platform 103 can be adaptively adjusted according to the specific structure and size parameters of the offshore photovoltaic support unit to meet the operational needs of the workers.
