Description

Technical Field

[0001] This utility model relates to the field of floating photovoltaic power station monitoring technology, and in particular to an Internet of Things platform for monitoring floating photovoltaic power stations. Background Technology

[0002] Floating photovoltaic (PV) power plants are an emerging form of clean energy generation that utilizes vast water resources by fixing PV modules to the water surface using floats, supports, and mooring systems. Compared to ground-mounted power plants, they offer multiple advantages, including not occupying arable land, reducing water evaporation, inhibiting algae growth, and lowering module operating temperatures to improve power generation efficiency. They have already been widely applied in lakes, reservoirs, coal mining subsidence areas, and near-shore areas both domestically and internationally.

[0003] However, existing monitoring equipment generally uses fixed poles or simple cantilever installations. Once the viewing angle and height of the camera or infrared sensor are set, they cannot be changed. When facing wide arrays, the only way to achieve coverage is to increase the number of points, which is costly and still has blind spots. At the same time, the monitoring unit and the floating platform are mostly fixed with a single direct bolt, lacking a composite structure for positioning and anti-loosening. Under long-term wind and wave loads, the bolts are prone to loosening and the sealing rings are prone to wear, which can lead to equipment overturning, water ingress or signal interruption. Frequent manual water replenishment is required for maintenance, which greatly increases operation and maintenance costs and safety risks. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides an Internet of Things (IoT) platform for monitoring floating photovoltaic power plants.

[0005] This utility model is achieved using the following technical solution: an IoT platform for monitoring a floating photovoltaic power station, comprising a support frame, a floating platform fixedly connected to the top of the support frame, a photovoltaic panel mounted on the top of the floating platform, a base connected to the top of the floating platform via a fastener, a fixing sleeve fixedly connected to the top of the base, a mounting box fixedly connected to the surface of the fixing sleeve, a motor I fixedly connected to the surface of the mounting box via bolts, a bevel gear I fixedly connected to the output end of the motor I, a bevel gear II meshing with the surface of the bevel gear I, a lead screw fixedly connected to the inner wall of the bevel gear II, a movable platform threadedly connected to the surface of the lead screw, a connecting rod fixedly connected to the surface of the movable platform, a motor II fixedly mounted at the end of the connecting rod away from the movable platform, and a monitor fixedly mounted at the output end of the motor II via a right-angle plate.

[0006] Through the above technical solution, the integrated setup of bracket, floating platform, photovoltaic panel, base, fixing sleeve, mounting box, motor one, bevel gear one, bevel gear two, lead screw, moving platform, connecting rod, motor two and monitor, motor one drives the lead screw to rotate through the bevel gear pair, the moving platform drives the connecting rod and monitor to achieve lifting and lowering, and motor two drives the monitor to rotate, so that the monitor can adjust its height and angle simultaneously in the floating state, achieving the effect of all-round, variable-view, blind-spot-free real-time monitoring of photovoltaic power station.

[0007] As a further improvement to the above solution, the output end of the motor penetrates through the inner wall of the mounting box, and the upper and lower ends of the lead screw are rotatably connected inside the fixed sleeve.

[0008] Through the above technical solution, the motor output end passes through the mounting box, and the two ends of the lead screw are rotated and supported inside the fixed sleeve, so that the bevel gear pair and the lead screw are enclosed and protected and supported at both ends, ensuring the coaxiality of the transmission and preventing the monitor from getting stuck due to cantilever deformation.

[0009] As a further improvement to the above solution, the connecting rod penetrates the inner wall of the fixing sleeve.

[0010] Through the above technical solution, the connecting rod penetrates the inner wall of the fixed sleeve, so that the axial movement of the moving stage is directly transmitted to the monitor outside the fixed sleeve.

[0011] Through the above technical solution, the mobile stage is equipped with a slider that slides in cooperation with the slide rail, transferring the overturning torque borne by the lead screw to the slide rail, preventing the mobile stage from deflecting, and ensuring the straightness of the monitor's lifting and lowering and the accuracy of its repeatability.

[0012] As a further improvement to the above solution, a slider is fixedly connected to the surface of the mobile platform, and a slide rail is slidably connected to the surface of the slider.

[0013] As a further improvement to the above solution, the end of the slide rail away from the slider is fixedly connected to the inner wall of the bracket.

[0014] As a further improvement to the above solution, the fixing component includes a mounting platform, the top of which has a slot, and a locking block is engaged inside the slot.

[0015] With the above technical solution, a slot is opened on the top of the mounting platform, and the base can be radially positioned by inserting the card block into the slot, without the need for additional clamps.

[0016] As a further improvement to the above solution, the top of the mounting platform is fixedly connected to the top of the floating platform, and the top of the locking block is fixedly connected to the bottom of the base.

[0017] Through the above technical solution, the mounting platform is fixedly connected to the top of the floating platform, and the clamp is fixedly connected to the bottom of the base, forming an upper and lower separate interface, which allows the monitoring device to be manufactured separately from the floating platform and then assembled, reducing the difficulty of modular production and transportation.

[0018] As a further improvement to the above solution, the base is fixedly connected to the top of the mounting platform by bolts.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model employs a lifting-rotation composite drive mechanism consisting of a motor, a bevel gear, a bevel gear, a lead screw, a moving platform, a connecting rod, and a monitor. The motor drives the lead screw to rotate via the bevel gear pair, causing the moving platform to move the connecting rod and the monitor up and down along the lead screw axis. The motor then drives the monitor to rotate in the horizontal plane, achieving synchronous adjustment of the monitor's height and angle. This enables real-time, accurate, and comprehensive monitoring of floating photovoltaic power stations at different heights and azimuth angles.

[0020] This utility model uses a snap-bolt composite fastener consisting of a mounting platform, a slot, a locking block, and bolts. During installation, the locking block is first inserted into the slot to complete radial positioning, and then the base is fastened to the mounting platform with bolts. This achieves rapid positioning and reliable locking between the fixed sleeve and the floating platform, and ensures that the overall stability of the monitoring device is maintained under the impact of wind and waves, preventing loosening and displacement, and facilitating later maintenance and disassembly.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0024] Please combine Figure 1-5 This embodiment of an IoT platform for monitoring a floating photovoltaic power station includes a support frame 1. A floating platform 2 is fixedly connected to the top of the support frame 1. A photovoltaic panel 3 is installed on the top of the floating platform 2. A base 4 is connected to the top of the floating platform 2 via a fastener. A fixing sleeve 5 is fixedly connected to the top of the base 4. A mounting box 6 is fixedly connected to the surface of the fixing sleeve 5. A motor 7 is fixedly connected to the surface of the mounting box 6 via bolts. A bevel gear 8 is fixedly connected to the output end of the motor 7. A bevel gear 9 is meshed with the surface of the bevel gear 8. A lead screw 10 is fixedly connected to the inner wall of the bevel gear 9. A moving platform 11 is threadedly connected to the surface of the lead screw 10. A connecting rod 12 is fixedly connected to the surface of the moving platform 11. A motor 13 is fixedly installed at the end of the connecting rod 12 away from the moving platform 11. A monitor 14 is fixedly installed at the output end of the motor 13 via a right-angle plate.

[0025] In use, start motor 7. The output of motor 7 drives bevel gear 8 to rotate. The rotation of bevel gear 8 synchronously drives bevel gear 9, which meshes with it, to rotate. This synchronously drives lead screw 10 to rotate. When lead screw 10 rotates, it drives moving platform 11 to move back and forth on the surface of lead screw 10. When lead screw 10 moves, it drives connecting rod 12 and monitor 14 to move synchronously with moving platform 11. This allows monitor 14 to be moved up and down at any time during monitoring, and the monitoring range of monitor 14 can be adjusted in real time. Start motor 13. The output of motor 13 drives monitor 14 to rotate, enabling the photovoltaic power station to be detected at different angles at any time.

[0026] The output end of motor 7 passes through the inner wall of mounting box 6, and the upper and lower ends of lead screw 10 are rotatably connected inside fixed sleeve 5. The output end of motor 7 passes through mounting box 6, and the two ends of lead screw 10 are rotatably connected inside fixed sleeve 5, so that the bevel gear pair and lead screw 10 are enclosed and protected and supported at both ends, ensuring the coaxiality of the transmission and preventing the monitor 14 from getting stuck due to cantilever deformation.

[0027] The connecting rod 12 penetrates the inner wall of the fixed sleeve 5, so that the axial movement of the moving stage 11 is directly transmitted to the monitor 14 outside the fixed sleeve 5.

[0028] A slider 15 is fixedly connected to the surface of the moving stage 11, and a slide rail 16 is slidably connected to the surface of the slider 15. The moving stage 11 is equipped with a slider 15 and slides with the slide rail 16 to transfer the overturning torque borne by the lead screw 10 to the slide rail 16 and prevent the moving stage 11 from deflecting.

[0029] The end of the slide rail 16 away from the slider 15 is fixedly connected to the inner wall of the bracket 1. The fixed end of the slide rail 16 is directly connected to the inner wall of the bracket 1, so that the reaction force generated by lifting is transmitted to the main bearing structure, avoiding local deformation of the floating platform 2 and improving the overall wind and wave resistance.

[0030] The fastener includes a mounting platform 17, with a slot 18 on the top of the mounting platform 17. A locking block 19 is engaged inside the slot 18. The slot 18 on the top of the mounting platform 17 and the locking block 19 can be inserted into the slot 18 to achieve radial positioning of the base 4 without the need for additional clamps.

[0031] The top of the mounting platform 17 is fixedly connected to the top of the floating platform 2, and the top of the locking block 19 is fixedly connected to the bottom of the base 4.

[0032] The base 4 is fixedly connected to the top of the mounting platform 17 by bolts.

[0033] The implementation principle of the IoT platform for monitoring a floating photovoltaic power station in this embodiment is as follows: When detecting the photovoltaic panels, motor 7 is started first. The output end of motor 7 drives bevel gear 8 to rotate. The rotation of bevel gear 8 synchronously drives bevel gear 9, which meshes with it, to rotate. This synchronously drives lead screw 10 to rotate. When lead screw 10 rotates, it drives moving platform 11 to move back and forth on the surface of lead screw 10. When lead screw 10 moves, it drives connecting rod 12 and monitor 14 to move synchronously with moving platform 11. This allows the monitor 14 to be moved up and down at any time during the monitoring process, and the monitoring range of monitor 14 can be adjusted in real time. Motor 13 is started. The output end of motor 13 drives monitor 14 to rotate, enabling the photovoltaic power station to be detected at different angles at any time.

[0034] When installing the fixing sleeve 5, first, the clip 19 is snapped into the inside of the slot 18 for positioning, and then the base 4 is fixed to the top of the slot 18 by bolt thread connection.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
