Description

Technical Field

[0001] The present invention belongs to the technical field of offshore photovoltaic panels, and in particular relates to a waterproof structure for a line joint of an offshore photovoltaic panel and a waterproof method thereof. Background Art

[0002] Offshore photovoltaic panels are photovoltaic power stations installed on the sea surface. They are primarily classified into pile-based and floating types. Pile-based photovoltaic panels are fixed to the seabed using steel piles and other structural members. This method offers greater stability and is suitable for deeper or more turbulent waters. Pile-based offshore photovoltaic systems often utilize a model that combines grid-connected power generation with fish-based solar power. Floating photovoltaic panels, however, are installed on floating structures that float on the sea surface. This method offers greater flexibility, allowing for adjustments in position and layout. Floating offshore photovoltaic systems often utilize a model that combines grid-connected power generation with cage aquaculture.

[0003] Regardless of the installation method used, photovoltaic panels must be connected to the panels using cables for power transmission. Since they are installed on the sea surface, the sealing between the photovoltaic panel connector and the cable is crucial, that is, how to maintain waterproof capabilities. In the existing technology, rubber rings or rubber pads are generally used to achieve waterproofing. This waterproofing method will gradually fail during the insertion and removal of the cables, and the overall waterproofness will decrease, affecting the waterproof effect.

[0004] Since photovoltaic panels are installed on the sea surface during use, they need to be maintained regularly. Conventional photovoltaic power stations are composed of an array of multiple photovoltaic panels, each of which is connected by cables. As a result, cables need to be plugged in every time maintenance is performed. This plugging method is affected by time and the forces on the sea surface. After long-term use, the joints will become loose, affecting normal power generation. Summary of the Invention

[0005] The object of the present invention is to provide a waterproof structure for an offshore photovoltaic panel line joint and a waterproof method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a waterproof structure for an offshore photovoltaic panel line joint, comprising a fixed box, a longitudinal card slot is provided on the front of the fixed box near the top, and transverse card slots are provided on the left and right sides of the front of the fixed box near the bottom. A female socket is fixedly installed on the back of the inner cavity of the fixed box, and a male socket is movably connected to the front of the fixed box. The male socket and the female socket are movably connected, and an extended guide rail is fixedly installed in the middle of the fixed box. The interior of the extended guide rail is movably connected to a limiting component, and the limiting component is fixedly connected to the outer side of the male socket. The interiors of the transverse card slots are movably connected to transverse card blocks. A limiting card plate is fixedly installed on the front of the card block, and horizontal guide rails located above the two horizontal card slots are fixedly installed on the left and right sides of the front of the fixed box. A linkage component is movably connected to the front of the longitudinal card slot, and the left and right sides of the bottom end of the linkage component are movably connected to the horizontal guide rails and connected to the middle part of the top of the limiting card plate. A sealing component is fixedly installed at the top position of the front of the fixed box, and the bottom end of the sealing component is connected to the linkage component. The other end of the sealing component passes through one end of the fixed box and is movably connected to the outer side surface of the socket male seat. When the socket male seat and the socket female seat are movably connected, the back side of the socket female seat is magnetically connected to the back side of the inner cavity of the fixed box.

[0007] In the initial state, the male socket and the female socket are not in the plug-in state. At this time, the female socket is in the frontmost state, and the limit assembly is also in the initial state. At this time, the distance between the two limit card plates is the maximum value, and the sealing assembly and the linkage assembly are also in the initial state.

[0008] As a further technical solution of the present invention, the limit assembly includes a limit sleeve, which is fixedly connected to the outer side surface of the socket male seat, and an extension block is fixedly installed on the top of the limit sleeve. The limit sleeve is movably connected between the extension block and the extension guide rail.

[0009] As a further technical solution of the present invention, first fixing seats are fixedly installed on both the left and right sides of the inner side of the limiting sleeve, and one end of the first fixing seat away from the limiting sleeve is movably connected to a first connecting rod through a rotating shaft.

[0010] As a further technical solution of the present invention, one end of the first connecting rod away from the first fixing seat is movably connected to the second fixing seat through a rotating shaft, and one end of the second fixing seat away from the first connecting rod is connected to the transverse clamping block.

[0011] When plugging the male socket and the female socket, the male socket and the female socket are aligned with each other, the male socket is kept in front of the female socket, and the plugging process of the male socket and the female socket is completed. After the plugging is completed, continue to apply pressure to the female socket. At this time, the female socket is displaced backward until the back of the female socket and the back of the inner side of the fixed box are adsorbed against each other. At this time, a backward thrust can be applied to the limit sleeve, and the limit sleeve is displaced backward under the guidance of the extended block and the extended guide rail. At this time, the two first connecting rods are moved closer to the middle until the two second fixed seats are driven relatively close.

[0012] As a further technical solution of the present invention, the linkage assembly includes a movable frame, a longitudinal clamping block is fixedly installed on the back of the movable frame, the movable frame is movably connected between the longitudinal clamping block and the longitudinal clamping slot, and the top of the longitudinal clamping block is fixedly installed with a limit spring located inside the longitudinal clamping slot, and the top of the limit spring is connected to the top of the inner cavity of the longitudinal clamping slot.

[0013] As a further technical solution of the present invention, a third fixed seat is fixedly installed on both sides of the left and right sides of the bottom end of the movable frame, and the end of the third fixed seat away from the movable frame is movably connected to the second connecting rod through a rotating shaft, and the end of the second connecting rod away from the third fixed seat is movably connected to the fourth fixed seat through a rotating shaft.

[0014] As a further technical solution of the present invention, a transverse guide block is fixedly installed at the bottom end of the fourth fixed seat, the transverse guide block is movably connected to the transverse guide rail, and the bottom end of the transverse guide block is connected to the middle part of the top end of the limiting card.

[0015] When the two second fixed seats are relatively close to each other, the two horizontal clamping blocks can be driven to be relatively close to each other. At this time, the two horizontal clamping blocks can drive the two limit clamping plates to be relatively close to each other under the action of the horizontal clamping groove, until the inner sides of the two limit clamping plates contact the outer sides of the male seat of the socket. When the female socket moves to the extreme position, the two limit clamping plates just complete the limit clamping connection with the male socket, completing the limit auxiliary fixing process.

[0016] By utilizing a simple plugging process, that is, the plugging process of the socket male seat and the socket female seat, and through the cooperation between the limit component and the limit card plate, the plugging action is converted into a force for the two second fixing seats to be relatively close, and finally the two limit card plates are driven relatively close, and the fixing process of the socket male seat is completed by the two limit card plates, so that after the socket male seat is installed in place, auxiliary fixation can be automatically completed to prevent falling off caused by long-term use, thereby improving the stability of the device.

[0017] At the same time, when the two limit plates are relatively close to each other, the two lateral guide blocks are relatively close to each other under the action of the two lateral guide rails, and a force is applied to the second connecting rod. At this time, the second connecting rod rotates and deflects toward the middle. At this time, the movable frame moves upward, and the longitudinal block moves relative to the longitudinal slot. At this time, the limit spring can be compressed until the movable frame rises to the highest point. When the limit spring is compressed to the limit position, it indicates that the male socket and the female socket are plugged into place.

[0018] By utilizing the plug-in effect of the male socket and the female socket, the two limit clamps can be brought relatively close to each other, and the power can be transmitted to the linkage component to achieve the upward displacement of the movable frame. The displacement state of the movable frame and the compression state of the limit spring are used to determine whether the male socket and the female socket are plugged in place. Whether they are plugged in place can be determined remotely, which is convenient for use during maintenance of offshore photovoltaic panels and improves maintenance efficiency.

[0019] As a further technical solution of the present invention, the sealing assembly includes an oil storage pipe, the top end of the oil storage pipe is fixedly connected to an oil delivery pipe, the end of the oil delivery pipe away from the oil storage pipe is fixedly connected to a rubber ring, and the rubber ring is movably connected to the part of the outer surface of the socket male seat located inside the fixed box.

[0020] As a further technical solution of the present invention, the oil storage tube is movably sleeved with a piston plate, the bottom end of the piston plate is fixedly connected to a piston rod, the bottom end of the piston rod passes through the bottom end of the oil storage tube and is connected to the top of the movable frame, the outer side surface of the piston rod is movably sleeved with a return spring, the upper and lower ends of the return spring are respectively connected to the bottom end of the inner cavity of the oil storage tube and the bottom end of the piston plate, and the top of the piston plate and the top of the inner cavity of the oil storage tube are filled with hydraulic oil.

[0021] When the movable frame moves upward, that is, when the socket male and socket female are plugged into each other, the piston rod moves upward accordingly, and drives the piston plate to move upward. At this time, the piston plate moves upward relative to the oil storage pipe, and the hydraulic oil inside the oil storage pipe is discharged through the oil pipe and enters the interior of the rubber ring, causing the rubber ring to expand. At this time, the volume of the rubber ring changes, and fills the gap between the inner side of the rubber ring and the socket male, realizing a sealed connection and completing the waterproof process.

[0022] By utilizing the plugging process between the male socket and the female socket, the male socket can be automatically limited and fixed. At the same time, the hydraulic oil can be automatically transported and the gap between the male socket and the rubber ring can be automatically filled through the cooperation between the linkage component and the sealing component. The whole process can be completed automatically, which can effectively avoid the degradation of waterproof performance caused by the gap. At the same time, the sealing is always maintained by pressurization, the sealing effect is improved, and the overall waterproof performance is improved.

[0023] A method for waterproofing a cable joint structure of an offshore photovoltaic panel comprises the following steps:

[0024] S1: When installing the male and female sockets, insert the male socket into the fixing box and snap-fit it to the female socket. After the fixing is completed, continue to push the female socket backward until the back of the female socket is magnetically connected to the back of the inner cavity of the fixing box, completing the snap-fit process and driving the limit sleeve to move backward at the same time.

[0025] S2: When the limit sleeve moves backward, it can synchronously drive the two first connecting rods to deflect toward the middle and apply force to the limit card plate. At this time, the two limit card plates can be driven relatively close to each other under the guidance of the horizontal card block until the inner side of the limit card plate contacts the outer side of the socket male seat, completing the limit fixing process;

[0026] S3: When the two limit plates are relatively close to each other, the two second connecting rods deflect toward the middle and apply thrust to the movable frame. At this time, the movable frame can move upward under the guidance of the longitudinal block. At this time, the limit spring can be compressed and transmit the force to the sealing assembly;

[0027] S4: The piston rod moves upward. At this time, the return spring can be stretched and drive the piston plate to move upward, which can generate pressure inside the oil storage pipe and squeeze the hydraulic oil inside the oil storage pipe to the oil delivery pipe. Finally, the rubber ring is filled and expanded, filling the gap between the inner side of the rubber ring and the socket male seat, completing the waterproof process.

[0028] The beneficial effects of the present invention are as follows:

[0029] (1) The present invention utilizes a simple plug-in process, that is, the plug-in process of the socket male seat and the socket female seat, and through the cooperation between the limit assembly and the limit card plate, the plug-in action is converted into a power for the two second fixing seats to be relatively close, and finally drives the two limit cards to be relatively close, and completes the fixing process of the socket male seat through the two limit card plates, so that after the socket male seat is installed in place, auxiliary fixation can be automatically completed to prevent falling off caused by long-term use, thereby improving the stability of the device.

[0030] (2) The present invention utilizes the plugging process between the male socket and the female socket to automatically limit and fix the male socket. At the same time, it can also automatically transport the hydraulic oil and automatically fill the gap between the male socket and the rubber ring through the cooperation between the linkage component and the sealing component. The whole process can be completed automatically, which can effectively avoid the degradation of waterproof performance caused by the gap. At the same time, the sealing is always maintained by pressurization, the sealing effect is improved, and the overall waterproof performance is improved.

[0031] (3) The present invention utilizes the plug-in effect of the male socket and the female socket to achieve the relative proximity of the two limit clamps, and can also transmit power to the linkage assembly and realize the upward displacement of the movable frame. The displacement state of the movable frame and the compression state of the limit spring are used to determine whether the male socket and the female socket are plugged in. Whether they are plugged in can be determined remotely, which is convenient for use during maintenance of offshore photovoltaic panels and improves maintenance efficiency.

A sealing component 8 is fixedly installed at the top position of the front of the fixed box 1. The bottom end of the sealing component 8 is connected to the linkage component 10. The other end of the sealing component 8 passes through one end of the fixed box 1 and is movably connected to the outer side surface of the socket male seat 4. When the socket male seat 4 and the socket female seat 5 are movably connected, the back of the socket female seat 5 is magnetically connected to the back of the inner cavity of the fixed box 1.

[0043] In the initial state, the male socket 4 and the female socket 5 are not in the plug-in state.

At this time, the distance between the two limit card plates 11 is the maximum value, and the sealing component 8 and the linkage component 10 are also in the initial state.

[0044] like Figure 2 and Figure 8As shown, the limit assembly 7 includes a limit sleeve 701, which is fixedly connected to the outer side surface of the socket male seat 4, and an extended clamping block 702 is fixedly installed on the top of the limit sleeve 701. The limit sleeve 701 is movably connected to the extended guide rail 6 through the extended clamping block 702. The left and right sides of the inner side surface of the limit sleeve 701 are fixedly installed with a first fixed seat 703, and the end of the first fixed seat 703 away from the limit sleeve 701 is movably connected to the first connecting rod 705 through a rotating shaft. The end of the first connecting rod 705 away from the first fixed seat 703 is movably connected to the second fixed seat 704 through a rotating shaft, and the end of the second fixed seat 704 away from the first connecting rod 705 is connected to the horizontal clamping block 12.

[0045] When plugging the male socket 4 and the female socket 5, the male socket 4 and the female socket 5 are aligned, the male socket 4 is kept in front of the female socket 5, and the plugging process of the male socket 4 and the female socket 5 is completed. After the plugging is completed, continue to apply pressure to the female socket 5. At this time, the female socket 5 is displaced to the rear side until the back side of the female socket 5 and the back side of the inner side of the fixed box 1 are adsorbed against each other. At this time, a backward thrust can be applied to the limit sleeve 701, and the limit sleeve 701 is displaced to the rear side under the guidance of the extended block 702 and the extended guide rail 6. At this time, the two first connecting rods 705 are moved toward the middle until the two second fixed seats 704 are driven relatively close.

[0046] like Figure 1 and Figure 2 as well as Figure 7 As shown, the linkage assembly 10 includes a movable frame 101, and a longitudinal clamping block 102 is fixedly installed on the back of the movable frame 101, and the movable frame 101 is movably connected between the longitudinal clamping block 102 and the longitudinal clamping slot 2. The top of the longitudinal clamping block 102 is fixedly installed with a limit spring 13 located inside the longitudinal clamping slot 2, and the top of the limit spring 13 is connected to the top of the inner cavity of the longitudinal clamping slot 2. The left and right sides of the bottom end of the movable frame 101 are fixedly installed with a third fixed seat 103, and the end of the third fixed seat 103 away from the movable frame 101 is movably connected to the second connecting rod 105 through a rotating shaft, and the end of the second connecting rod 105 away from the third fixed seat 103 is movably connected to the fourth fixed seat 104 through a rotating shaft, and the bottom end of the fourth fixed seat 104 is fixedly installed with a transverse guide block 106, which is movably connected to the transverse guide rail 9, and the bottom end of the transverse guide block 106 is connected to the middle part of the top of the limit clamping plate 11.

[0047] Embodiment: When the two second fixing seats 704 are relatively close to each other, the two horizontal clamping blocks 12 can be driven to be relatively close to each other. At this time, the two horizontal clamping blocks 12 can drive the two limiting clamping plates 11 to be relatively close to each other under the action of the horizontal clamping groove 3, until the inner side surfaces of the two limiting clamping plates 11 contact the outer side surfaces of the socket male seat 4. When the socket female seat 5 moves to the extreme position, the two limiting clamping plates 11 just complete the limiting clamping connection with the socket male seat 4, completing the limiting auxiliary fixing process.

[0048] By utilizing a simple plugging process, that is, the plugging process of the socket male seat 4 and the socket female seat 5, and through the cooperation between the limit component 7 and the limit card plate 11, the plugging action is converted into a force for the two second fixing seats 704 to be relatively close, and finally the two limit card plates 11 are driven relatively close, and the fixing process of the socket male seat 4 is completed by the two limit card plates 11, so that after the socket male seat 4 is installed in place, auxiliary fixation can be automatically completed to prevent falling off caused by long-term use, thereby improving the stability of the device.

[0049] At the same time, when the two limit plates 11 are relatively close to each other, the two transverse guide blocks 106 are relatively close to each other under the action of the two transverse guide rails 9, and a force is applied to the second connecting rod 105. At this time, the second connecting rod 105 rotates and deflects toward the middle. At this time, the movable frame 101 moves upward, and the longitudinal block 102 moves relative to the longitudinal slot 2. At this time, the limit spring 13 can be compressed until the movable frame 101 rises to the highest point. When the limit spring 13 is compressed to the extreme position, it indicates that the male socket 4 and the female socket 5 are plugged into place.

[0050] By utilizing the plug-in effect of the male socket 4 and the female socket 5, the two limit clamps 11 are brought relatively close together, and power can be transmitted to the linkage assembly 10, and the upward displacement of the movable frame 101 is achieved. The displacement state of the movable frame 101 and the compression state of the limit spring 13 are used to determine whether the male socket 4 and the female socket 5 are plugged in place, and whether they are plugged in place can be determined remotely, which is convenient for use during maintenance of offshore photovoltaic panels and improves maintenance efficiency.

[0051] like Figure 1 and Figure 4 as well as Figure 5 and Figure 6As shown, the sealing assembly 8 includes an oil storage pipe 801, the top of the oil storage pipe 801 is fixedly connected to the oil delivery pipe 802, and the end of the oil delivery pipe 802 away from the oil storage pipe 801 is fixedly connected to a rubber ring 806, and the rubber ring 806 is movably connected to the part of the outer side surface of the socket male seat 4 located inside the fixed box 1, and the interior of the oil storage pipe 801 is movably connected to a piston plate 803, and the bottom end of the piston plate 803 is fixedly connected to a piston rod 804, and the bottom end of the piston rod 804 passes through the bottom end of the oil storage pipe 801 and is connected to the top of the movable frame 101, and the outer side surface of the piston rod 804 is movably connected to a return spring 805, and the upper and lower ends of the return spring 805 are respectively connected to the bottom end of the inner cavity of the oil storage pipe 801 and the bottom end of the piston plate 803, and the top of the piston plate 803 and the top of the inner cavity of the oil storage pipe 801 are filled with hydraulic oil.

[0052] Embodiment: When the movable frame 101 moves upward, that is, when the socket male seat 4 and the socket female seat 5 are plugged into each other, the piston rod 804 moves upward accordingly, and drives the piston plate 803 to move upward. At this time, the piston plate 803 moves upward relative to the oil storage pipe 801, and the hydraulic oil inside the oil storage pipe 801 is discharged through the oil pipe 802 and enters the interior of the rubber ring 806, causing the rubber ring 806 to expand. At this time, the volume of the rubber ring 806 changes, and fills the gap between the inner side of the rubber ring 806 and the socket male seat 4, realizing a sealed connection and completing the waterproof process.

[0053] By utilizing the plugging process between the male socket 4 and the female socket 5, the male socket 4 can be automatically limited and fixed. At the same time, the hydraulic oil can be automatically transported and the gap between the male socket 4 and the rubber ring 806 can be automatically filled through the cooperation between the linkage component 10 and the sealing component 8. The whole process can be completed automatically, which can effectively avoid the degradation of waterproof performance due to the gap. At the same time, the sealing is always maintained by pressurization, the sealing effect is improved, and the overall waterproof performance is improved.

[0054] A method for waterproofing a cable joint structure of an offshore photovoltaic panel comprises the following steps:

[0055] S1: When installing the male socket 4 and the female socket 5, the male socket 4 can be inserted into the interior of the fixing box 1 and fixed with the female socket 5 by snapping. After the fixation is completed, the female socket 5 can be pushed backward until the back of the female socket 5 is magnetically connected with the back of the inner cavity of the fixing box 1, completing the snap-fitting process and driving the limit sleeve 701 to move backward at the same time;

[0056] S2: When the limiting sleeve 701 moves backward, it can synchronously drive the two first connecting rods 705 to deflect toward the middle and apply a force to the limiting card plate 11. At this time, the two limiting card plates 11 can be driven relatively close to each other under the guidance of the transverse card block 12 until the inner side of the limiting card plate 11 contacts the outer side of the socket male seat 4, completing the limiting and fixing process;

[0057] S3: When the two limit clamping plates 11 are relatively close to each other, the two second connecting rods 105 are deflected toward the middle and exert a thrust on the movable frame 101. At this time, the movable frame 101 can move upward under the guidance of the longitudinal clamping block 102. At this time, the limit spring 13 can be compressed and transmit the force to the sealing assembly 8;

[0058] S4: The piston rod 804 moves upward, and the return spring 805 can be stretched at this time, driving the piston plate 803 to move upward, thereby generating pressure inside the oil storage pipe 801 and squeezing the hydraulic oil inside the oil storage pipe 801 to the oil delivery pipe 802, and finally filling the rubber ring 806, causing it to expand and fill the gap between the inner surface of the rubber ring 806 and the socket male seat 4, completing the waterproof process.
