Description

Technical Field

[0001] This invention belongs to the field of photovoltaic power generation, specifically a device for mechanical and telecommunication connections between floating power generation units. Background Technology

[0002] At present, the replacement of fossil fuels by clean energy represented by wind power and photovoltaics is an inevitable trend, and the transformation from traditional energy to new energy is imperative. However, with the large-scale construction of photovoltaic and wind power, the development bottlenecks of the two industries are becoming increasingly apparent.

[0003] In the prior art, Chinese Patent Application No. CN202311098155.9 discloses a high-altitude power transmission device, including a cable, a floating assembly, and a tethering guy wire. The floating assembly is connected to the outside of the cable, and each floating assembly includes two or more floats, with adjacent floats combined in a horizontal and / or vertical direction. The floats are filled with a gas with a density less than air, enabling the cable to be lifted into the air. This invention provides a solution for transmitting electricity generated by large-scale aerial power generation equipment to the ground via cables. The floating assembly lifts the cable segment by segment according to its weight, and the tethering guy wire stabilizes the cable's attitude in the air, ensuring it does not sway with the wind.

[0004] However, although the above-mentioned application can stabilize the cable's attitude in the air by using a tethered guy wire to ensure that it does not sway with the wind, the floating power generation units are only connected by simple connectors, which are not strong enough and are prone to falling off at high altitudes. Furthermore, they do not have communication and power transmission functions and rely on external cables for power transmission or communication, which are prone to tangling under the influence of wind.

[0005] To address the problems raised in the background art, those skilled in the art have proposed a device for mechanical and telecommunication connections between floating power generation units. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a device for mechanical and telecommunication connections between floating power generation units. This addresses the issues that while existing technologies can stabilize cables in the air by using tethered wires to prevent them from swaying in the wind, the connections between floating power generation units rely solely on simple connectors, resulting in low connection strength and a tendency to detach at high altitudes. Furthermore, these devices lack communication and power transmission capabilities, relying on external cables for power transmission or communication, which are prone to tangling under wind conditions.

[0007] A device for mechanical and telecommunication connection between floating photovoltaic power generation units includes floating photovoltaic power generation units and connecting components. The floating photovoltaic power generation units are arranged in a hexagonal prism shape. The upper and lower parts of the six corners of the floating photovoltaic power generation units are provided with plug-in components. The connecting components include connecting spheres. The upper surface of the connecting spheres is provided with three connecting blocks, and the lower surface of the connecting spheres is provided with another three connecting blocks. The two sets of connecting blocks are symmetrically arranged around the center of the connecting spheres. A plug-in groove is opened on the side of the connecting block away from the connecting sphere, and a plug-in pipe is fixedly installed in the plug-in groove.

[0008] Preferably, the top and bottom of the connecting sphere are provided with positioning rings, and a cable tube is provided inside the positioning ring. The cable tube passes through the connecting sphere and is provided with six power transmission cables. The power transmission cables are hollow copper tube conductors with an outer diameter of 30 mm and a wall thickness of 5 mm. The inside of the power transmission cables is filled with thermally conductive gel.

[0009] Preferably, a communication cable is provided between the six power transmission cables. The communication cable includes a main optical fiber channel, a PLC backup channel, and a protocol line. The communication interface of the communication cable is equipped with a power harmonic filter, an optical fiber transceiver, and a PLC coupler. The power harmonic filter is used to block noise >100kHz. The optical fiber transceiver is used for differential transmission and anti-saturation design. The PLC coupler is used for bandpass filtering and adaptive impedance matching.

[0010] Preferably, two matching compartments are provided on the side wall of the plug slot, and a second connection interface is provided inside each of the two matching compartments. The two second connection interfaces are a power transmission interface and a communication interface, respectively, and three positioning grooves are provided on the surface of the plug tube.

[0011] Preferably, the plug-in assembly includes a fixing rod, which is fixedly connected to the floating photovoltaic power generation unit. A connecting rod is fixedly connected to the end of the fixing rod away from the floating photovoltaic power generation unit, and a plug-in rod is provided at the end of the connecting rod away from the fixing rod.

[0012] Preferably, a fixing block is fixedly connected to the outer side of the plug rod. Two fixing blocks are provided on the outer side of the plug rod. A plug connector is provided on the side of the two fixing blocks away from the floating photovoltaic power generation unit. A first connection interface is provided on the side of the two plug connectors away from the fixing blocks. The two first connection interfaces are a communication interface and a power transmission interface, respectively.

[0013] Preferably, the connecting rod has an outer ring plate, the plug rod has a limiting groove, the plug rod is matched and connected to the plug tube, the limiting groove is matched and connected to the limiting rod, and the inner side of the ring plate has three arc-shaped plates, with a spring between each arc-shaped plate and the ring plate.

[0014] Preferably, the inner side of the limiting groove is provided with three moving grooves, each of which is L-shaped. A positioning block is provided inside the moving groove, and the positioning block matches the positioning groove. A connecting rod is rotatably connected to the bottom of the positioning block. A pull rod is provided at the end of the connecting rod away from the positioning block. The pull rod passes through the plug rod and extends to the outside of the plug rod. The end of the pull rod located outside the plug rod is fixedly connected to the arc plate. The moving groove connects the outside of the plug rod and the limiting groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This invention connects the plug-in assembly and connecting assembly of the floating photovoltaic power generation unit, lifts the arc-shaped plate upward, presses the spring component upward, thereby moving the pull rod and connecting rod upward, and moving the positioning block upward, so that the plug-in rod can enter the plug-in slot, so that the plug-in rod is located in the plug-in tube inside the plug-in slot, and the limiting groove inside the plug-in rod matches and connects with the limiting rod. When the limiting rod is fully inserted into the limiting groove, the position of the positioning block and the positioning groove will correspond. At this time, there will be a gap between the positioning block and the positioning groove. The elastic force of the spring component will drive the arc-shaped plate, pull rod and connecting rod downward, thereby matching the positioning block with the positioning groove and fixing one side of the floating power generation unit. By repeating the operation, the floating power generation units can be connected.

[0017] 2. When connecting the floating photovoltaic power generation units, the plug on the side of the fixing block will match and connect with the matching compartment inside the plug slot, thereby matching and connecting the first connection interface with the second connection interface. Both the first and second connection interfaces are provided in twos, namely a communication interface and a power transmission interface, so that the floating photovoltaic power generation unit can take on the functions of communication and power transmission. There is no need to connect external communication and power transmission cables to the surface of the floating photovoltaic power generation unit, making it lighter and more convenient to use. When connecting the floating photovoltaic power generation units, the parallel connection of power transmission and communication lines can be completed.

[0018] 3. This invention lifts the arc-shaped plate, causing it to press the spring component upwards, which in turn moves the pull rod and connecting rod upwards, and moves the positioning block upwards. At this time, the connecting rod is pulled outwards, allowing it to move the fixing rod outwards, thereby causing the connector to leave the matching chamber and the connector rod to leave the connector tube, thus disassembling the floating photovoltaic power generation unit.

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0029] As attached Figure 1 To be continued Figure 7 As shown:

[0030] Example 1: The present invention provides a device for mechanical and telecommunication connection between floating photovoltaic power generation units, including a floating photovoltaic power generation unit and a connecting assembly. The floating photovoltaic power generation unit is arranged in a hexagonal prism shape. The connecting assembly includes a connecting sphere. Three connecting blocks are arranged on the upper surface of the connecting sphere, and another three connecting blocks are arranged on the lower surface of the connecting sphere. The two sets of connecting blocks are symmetrically arranged around the center of the connecting sphere. A plug-in groove is opened on the side of the connecting block away from the connecting sphere, and a plug-in pipe is fixedly installed in the plug-in groove.

[0031] Furthermore, positioning rings are provided at the top and bottom of the connecting sphere, and cable conduits are provided inside the positioning rings. The cable conduits penetrate the connecting sphere and contain six power transmission cables. The power transmission cables are hollow copper tube conductors with an outer diameter of 30mm and a wall thickness of 5mm. The interior of the power transmission cables is filled with thermally conductive gel. Communication cables are provided between the six power transmission cables. The communication cables include a fiber optic main channel, a PLC backup channel, and a protocol line. The communication interface of the communication cables is equipped with a power harmonic filter, a fiber optic transceiver, and a PLC coupler. The power harmonic filter is used to block noise >100kHz, the fiber optic transceiver is used for differential transmission and anti-saturation design, and the PLC coupler is used for bandpass filtering and adaptive impedance matching.

[0032] Furthermore, two matching compartments 311 are provided on the side wall of the plug slot, and a second connection interface is provided inside each of the two matching compartments. The two second connection interfaces are a power transmission interface and a communication interface, respectively. Three positioning grooves are provided on the surface of the plug tube.

[0033] As can be seen from the above, when connecting the floating photovoltaic power generation units, the plug on the side of the fixing block will match and connect with the matching compartment inside the plug slot, thereby matching and connecting the first connection interface with the second connection interface. Both the first and second connection interfaces are provided with two interfaces, namely a communication interface and a power transmission interface, so that the floating photovoltaic power generation unit can take on the functions of communication and power transmission. There is no need to connect external communication and power transmission cables on the surface of the floating photovoltaic power generation unit, making it lighter and more convenient to use. Moreover, the parallel connection of power transmission and communication lines can be completed when connecting floating photovoltaic power generation units, making it more convenient to use.

[0034] Example 2: This example is basically the same as the previous example, except that the upper and lower parts of the six corners of the floating photovoltaic power generation unit are provided with plug-in components. The plug-in components include a fixing rod, which is fixedly connected to the floating photovoltaic power generation unit. A connecting rod is fixedly connected to the end of the fixing rod away from the floating photovoltaic power generation unit, and a plug-in rod is provided at the end of the connecting rod away from the fixing rod.

[0035] Furthermore, a fixing block is fixedly connected to the outer side of the plug-in rod. Two fixing blocks are provided on the outer side of the plug-in rod. Each fixing block has a plug connector on the side away from the floating photovoltaic power generation unit. Each plug connector has a first connection interface on the side away from the fixing block. The two first connection interfaces are a communication interface and a power transmission interface, respectively. A ring plate is provided on the outer periphery of the connecting rod. A limiting groove is formed inside the plug-in rod. The plug-in rod is matched and connected to the plug-in tube. The limiting groove is matched and connected to the limiting rod. The ring plate... Three arc-shaped plates are provided on the inner side, and a spring is provided between each arc-shaped plate and the ring plate. Three moving grooves are opened on the inner side of the limiting groove. Each moving groove is L-shaped and has a positioning block inside. The positioning block matches the positioning groove. A connecting rod is rotatably connected to the bottom of the positioning block. A pull rod is provided at the end of the connecting rod away from the positioning block. The pull rod passes through the plug rod and extends to the outside of the plug rod. The end of the pull rod outside the plug rod is fixedly connected to the arc-shaped plate. The moving groove connects the outside of the plug rod and the limiting groove.

[0036] As can be seen from the above, by matching and connecting the plug-in components and connecting components of the floating photovoltaic power generation unit, the arc plate is lifted upward, causing the arc plate to press the spring component upward, thereby driving the pull rod and connecting rod to move upward, and driving the positioning block to move upward, so that the plug rod can enter the plug slot, so that the plug rod is located in the plug tube inside the plug slot, and the limiting groove inside the plug rod matches and connects with the limiting rod. When the limiting rod is fully inserted into the limiting groove, the position of the positioning block and the positioning groove will correspond. At this time, there will be a gap between the positioning block and the positioning groove. The elastic force of the spring component will drive the arc plate and the pull rod and connecting rod to move downward, thereby making the positioning block match the positioning groove and fixing one side of the floating power generation unit. By repeating the operation, the floating power generation units can be connected.

[0037] When disassembly is required, the arc-shaped plate is lifted, causing it to press upward against the spring, which in turn moves the pull rod and connecting rod upward, and moves the positioning block upward. At this time, the connecting rod is pulled outward, allowing it to move the fixing rod outward, thereby causing the connector to leave the matching chamber and the connector rod to leave the connector tube, thus disassembling the floating photovoltaic power generation unit.

[0038] Working principle:

[0039] Connection: Connect the plug-in components and connecting components of the floating photovoltaic power generation unit. Lift the arc plate upwards to press the spring component, which in turn moves the pull rod and connecting rod upwards, and moves the positioning block upwards. This allows the plug rod to enter the plug slot, positioning it inside the plug tube within the slot. The limiting groove inside the plug rod matches the limiting rod. When the limiting rod is fully inside the limiting groove, the positioning block and positioning groove will correspond. At this time, there will be a gap between the positioning block and the positioning groove. The elastic force of the spring component will move the arc plate, pull rod, and connecting rod downwards, thus matching the positioning block with the positioning groove and fixing one side of the floating power generation unit. Repeat the operation to connect the floating power generation units.

[0040] Communication and power transmission: When connecting the floating photovoltaic power generation unit, the plug on the side of the fixing block will match the matching compartment inside the plug slot, thereby matching the first connection interface with the second connection interface. Both the first and second connection interfaces are provided in twos, namely a communication interface and a power transmission interface, so that the floating photovoltaic power generation unit can take on the functions of communication and power transmission. There is no need to connect external communication and power transmission cables to the surface of the floating photovoltaic power generation unit, making the whole unit lighter.

[0041] Disassembly: By lifting the arc-shaped plate, the arc-shaped plate presses the spring component upward, which in turn moves the pull rod and connecting rod upward, and moves the positioning block upward. At this time, the connecting rod is pulled outward, so that the connecting rod can move the fixing rod outward, thereby causing the plug to leave the matching chamber. At the same time, the plug rod leaves the plug tube, thus disassembling the floating photovoltaic power generation unit.
