Description

Technical Field

[0001] This invention relates to the field of new energy application technology and provides a photovoltaic monitoring device. Background Technology

[0002] It is estimated that 1.78 billion kilowatts of solar energy radiates to Earth annually, of which 50-100 billion kilowatt-hours are exploitable. However, due to its dispersed distribution, only a small portion is usable. Geothermal energy resources refer to the total heat content of rocks and water bodies within 5000 meters below the land. Of this, high-temperature geothermal energy resources within 3 kilometers of the global landmass, exceeding 150°C, are equivalent to 1.4 million tons of standard coal equivalent, and some countries have already begun commercial development and utilization. The global wind energy potential is approximately 350 billion kilowatts. Due to the intermittent and dispersed nature of wind power, its economic utilization is difficult. Significant improvements in energy transmission and storage technologies will increase wind power utilization in the future. Ocean energy, including tidal energy, wave energy, and ocean thermal energy conversion, has considerable theoretical reserves. However, due to technological limitations, it is currently in the small-scale research stage. Currently, because the utilization technologies for new energy sources are not yet mature, they only account for a small portion of the world's total energy needs, but they have great potential for future development.

[0003] Surveillance is one of the most widely used systems in security systems. It consists of a complete set of equipment, including cameras, video recorders, monitors, switches, and network cables, to achieve monitoring. Photovoltaic surveillance equipment uses solar photovoltaic panels to generate electricity for the surveillance equipment, thus achieving energy conservation and environmental protection. Surveillance can be applied to almost all industries, bringing great convenience to people's lives, work, and production.

[0004] Photovoltaic monitoring equipment is particularly suitable for large-area, distributed monitoring, featuring no wiring required, wide coverage, and low power consumption. However, while providing extensive coverage, it also increases the failure rate and maintenance difficulty. Currently, photovoltaic monitoring equipment is generally installed on high fixed poles. When the photovoltaic or monitoring equipment malfunctions or requires maintenance, repair workers need to use climbing tools to ascend the fixed poles or use lifting and ascending equipment for maintenance. Such maintenance operations are not convenient or efficient. Therefore, the performance of existing photovoltaic monitoring equipment cannot meet the needs of maintenance and improvement.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Example 1, by Figures 1 to 8The present invention includes a fixed base 1, on the top of which two rotating rods 1 and 2 are symmetrically mounted. A rotating rod 2 and 3 are rotatably connected to the top of each of the two rotating rods 1 and 2. A mounting plate 4 is installed between the tops of the two rotating rods 2 and 3. A square lifting rod 5 is installed in the middle of the mounting plate 4. An inverted L-shaped mounting rod 6 is rotatably connected to the top of the square lifting rod 5. A monitor 7 and a photovoltaic panel 8 are mounted on the upper part of the inverted L-shaped mounting rod 6, with the photovoltaic panel 8 providing power to the monitor 7. A rotating rod 3 and 10 are rotatably mounted on the inner sides of each of the two rotating rods 1 and 2. A connecting plate 9 is installed between one end of each of the two rotating rods 3 and 10. A limiting plate 24 is fixedly mounted at the bottom of the square lifting rod 5. Two insert rods 25 are fixedly mounted on both sides of the top of the limiting plate 24. The four insert rods... The rods 25 are all inserted into the mounting plate 4. The mounting plate 4 has four through holes in the middle. The rods 25 are inserted into the through holes, which are not shown in the attached drawings. This allows the square lifting rod 5 to be adjusted stably and effectively. The mounting plate 4 has a square mounting slot 11 in the middle. The square lifting rod 5 is installed inside the square mounting slot 11. The mounting plate 4 has symmetrical inverted convex slots 12 on both sides. Both inverted convex slots 12 are connected to the middle of the square mounting slot 11. Both inverted convex slots 12 have racks 13 installed inside. The bottom of both racks 13 is fixedly connected to the top of the connecting plate 9. Both inverted convex slots 12 have lifting adjustment components installed in the middle. The lifting adjustment components are connected between the racks 13 and the square lifting rod 5. Both lifting adjustment components include a large gear 14 and a small gear 15, which are rotatably mounted in the middle of the inverted convex groove 12. The large gear 14 and the small gear 15 are meshed together. Two racks 16 are installed on both sides of the surface of the square lifting rod 5. The small gear 15 meshes with the rack 16, and the large gear 14 meshes with the rack 13, thus effectively adjusting the height of the square lifting rod 5. Two U-shaped mounting blocks 17 are symmetrically installed on the top of the fixed base 1. The rotating rods 12 are rotatably connected to the U-shaped mounting blocks 17 via connecting pins 18. A protective shell 19 is fixedly installed on one side of the top of the fixed base 1. One end of each of the two connecting pins 18 extends into the interior of the protective shell 19 and is fitted with a worm gear 21. The device is internally equipped with a dual-shaft motor 22, with worm gears 23 mounted at both ends. Each worm gear 23 meshes with a worm wheel 21. The worm wheels 21 and worm gears 23 are symmetrically arranged to provide effective adjustment power. Starting the dual-shaft motor 22 drives the two worm gears 23 to rotate. This rotation drives the two worm wheels 21, which in turn drives the two connecting pins 18 to rotate relative to each other. The two relatively rotating connecting pins 18 then drive the two rotating rods 2 to rotate relative to each other for adjustment. As shown in the attached diagram, the entire device is in a maintenance state, facilitating maintenance of the monitor 7 and the photovoltaic panel 8 by workers.After maintenance, by rotating the two rotating rods 1-2, they rotate relative to each other. This relative rotation of the two rotating rods 1-2 causes the two rotating rods 2-3 to rotate, thus pressing and lifting the mounting plate 4. Simultaneously, the relative rotation of the two rotating rods 1-2 pushes the two rotating rods 3-10, raising the position of the connecting plate 9. The upward movement of the connecting plate 9 causes the two racks 1-13 to move upward, which in turn drives the large gear 14 to rotate. The rotation of the large gear 14... This will cause the square lifting rod 5 to rotate, and the rotation of the square lifting rod 5 will drive the rack 16 to move upward. The upward movement of the rack 16 will cause the square lifting rod 5 to move upward inside the square mounting slot 11. Finally, the two rotating rods 2 and 3 are all perpendicular to the fixed base 1, and the height of the square lifting rod 5 is also adjusted upward. The upward movement of the square lifting rod 5 will drive the inverted L-shaped mounting rod 6, the monitor 7, and the photovoltaic panel 8 to move upward, so that the monitor 7 and the photovoltaic panel 8 can be used effectively.

[0033] In Example 2, based on Example 1, a transmission cavity 26 is provided in the middle of the upper part of the square lifting rod 5. A rotation adjustment end is installed at the lower part of the transmission cavity 26, and a rotation shaft 27 is rotatably installed at the top of the transmission cavity 26. The rotation adjustment end is connected to the rotation shaft 27. One end of the rotation shaft 27 extends to one side of the square lifting rod 5 and is fixedly connected to the inverted L-shaped mounting rod 6. A vertical groove 28 is provided on one side of the inside of the square mounting through groove 11. A short rack 29 is installed inside the vertical groove 28. The rotation adjustment end is connected to the short rack 29, so that the inverted L-shaped mounting rod 6 can be effectively rotated and adjusted. The rotation adjustment end includes a rotation pin 30, which is rotatably installed in the lower part of the transmission cavity 26. A gear 31 is fixedly installed in the middle of the rotation pin 30. An arc-shaped through-hole 32 is provided in the upper part of the square lifting rod 5. The gear 31 is meshed with the short rack 29 through the arc-shaped through-hole 32, so that transmission can be performed during the movement of the square lifting rod 5. A sprocket 33 is fixedly mounted on one side of the rotating pin 30. A rotating pin 34 is rotatably mounted on the upper part of the transmission cavity 26. A sprocket 35 is fixedly mounted on one side of the rotating pin 34. A chain 36 is installed between the sprocket 35 and the sprocket 33, thus enabling effective transmission. When the square lifting rod 5 moves upward, it will drive the gear 31 to move upward. Since the gear 31 is meshed with the short rack 29, the gear 31 will rotate during the upward movement. The rotation of shaft 31 will drive the rotation pin 30 and sprocket 33 to rotate. The rotation of sprocket 33 will drive the rotation of sprocket 35 and rotation pin 34 via chain 36. A worm gear 38 is fixedly installed at the other end of the rotating shaft 27, and a worm 37 is fixedly installed in the middle of the rotation pin 34. The worm 37 meshes with the worm gear 38, thus effectively driving the inverted L-shaped mounting rod 6 to rotate 90°, enabling the monitor 7 and photovoltaic panel 8 to function effectively. Figure 1 As shown, the inverted L-shaped mounting rod 6 is parallel to the ground, making it convenient for people to perform maintenance operations on the monitor 7 and the photovoltaic panel 8. When the square lifting rod 5 moves upward, the rotating pin 34 will drive the worm gear 37 to rotate. The rotation of the worm gear 37 will drive the worm wheel 38 to rotate. The rotation of the worm wheel 38 will drive the rotating shaft 27 to rotate. The rotation of the rotating shaft 27 will drive the inverted L-shaped mounting rod 6 to rotate 90°, so that the inverted L-shaped mounting rod 6 is relatively perpendicular to the ground, allowing the monitor 7 and the photovoltaic panel 8 to be raised to a higher level for easy use.

[0034] In Example 3, based on Example 2, an adjusting plate 39 is provided at the lower part of the transmission cavity 26 and on one side of the gear 31. Springs 40 are connected to both ends of one side of the adjusting plate 39 and the inner wall of the transmission cavity 26. An arc-shaped tooth block 41 is fixedly installed on the other side of the springs 40. An installation port 42 is opened on one side of the lower part of the transmission cavity 26. A scissor bracket 43 is rotatably installed in the middle of the installation port 42. An inverted convex vertical groove 44 is opened on the other side of the adjusting plate 39. Two inverted convex sliders 45 are slidably installed inside the inverted convex vertical groove 44. Springs 46 are connected to both ends of the two inverted convex sliders 45 and both ends of one side of the inverted convex vertical groove 44. An arc-shaped groove 47 is opened at the top of the other side of the square installation slot 11, thereby effectively clamping and fixing the gear 31, maintaining the stability and firmness of the vertical position of the inverted L-shaped mounting rod 6. Figure 7 and Figure 8 As shown, the other two ends of the scissor bracket 43 are pressed against the inner wall of the square mounting slot 11 for rotational adjustment. The rotational adjustment of the scissor bracket 43 will drive the two inverted convex sliders 45 to move towards both ends inside the inverted convex vertical slot 44, compressing the second spring 46. The rotational adjustment of the scissor bracket 43, through the two inverted convex sliders 45, will drive the adjusting plate 39 to move, compressing the first spring 40. The movement of the adjusting plate 39 will drive the arc-shaped toothed block 41 to move, causing the arc-shaped toothed block 41 to separate from the third gear 31, ultimately enabling the third gear 31 to effectively rotate. When the square lifting rod 5 moves upward and the inverted L-shaped mounting rod 6 rotates 90°, the monitor 7 and the photovoltaic power generation panel 8 are raised to a higher level for convenient use. After the L-shaped mounting rod 6 rotates 90°, gear 31 will separate from the short rack 29. Then, as the square lifting rod 5 continues to move upward, the scissor bracket 43 will move out of the inside of the square mounting slot 11. After the scissor bracket 43 loses the compression of the square mounting slot 11, the elastic restoring force of spring 1 40 and spring 2 46 will cause the scissor bracket 43 to rotate and push the adjusting plate 39 and the arc-shaped toothed block 41 to move through the two inverted convex sliders 45. This causes the arc-shaped toothed block 41 to lock and fix gear 31, thus ensuring that gear 31 will not rotate. The non-rotation of gear 31 will keep the inverted L-shaped mounting rod 6 relatively perpendicular to the ground and maintain a stable 90° position, thus effectively ensuring the stable use of the monitor 7 and the photovoltaic power generation panel 8.

[0035] This photovoltaic monitoring equipment features an easily adjustable support structure that can be effectively folded, raised, lowered, and rotated, facilitating convenient maintenance, installation, and disassembly. The support structure is also easy to use and operate, and its support and adjustment are stable and reliable. Therefore, the performance of this photovoltaic monitoring equipment meets the needs of maintenance.
