Description

Technical Field

[0001] This invention relates to the field of intersection sentry technology, specifically a level crossing safety warning system integrating radar and audio-visual warning units. Background Technology

[0002] Level crossings commonly suffer from blind spots, mixed pedestrian and vehicle traffic, and a lack of traffic lights, among other safety concerns. Using intersection sentinels is a key measure to address these safety shortcomings. Intersection sentinels, also known as intersection accident warning systems, are intelligent traffic safety warning devices deployed at intersections without traffic lights or with poor visibility. Relying on millimeter-wave radar and AI-powered cameras to sense road conditions, they simultaneously activate LED screen text prompts, high-volume voice announcements, and red and blue flashing lights when vehicles or pedestrians enter dangerous areas, achieving a proactive warning system integrating sound, light, and electricity. Currently, most intersection sentinels are solar-powered, enabling stable operation in adverse environments such as rain, fog, and nighttime, placing high demands on the reliability of the power supply system.

[0003] As the core power supply component of intersection sentinels, the photovoltaic conversion efficiency of solar panels directly affects the continuous operation of the equipment. However, intersection sentinels are deployed outdoors along roads for extended periods, and their solar panel surfaces easily accumulate pollutants such as road dust, exhaust particles, bird droppings, and fallen leaves. These pollutants not only block sunlight but can also create localized hot spots, leading to a significant decrease in the solar panel's output power and even causing permanent damage. Especially during dry seasons or at intersections with high traffic volume, dust accumulates even faster, reducing power generation efficiency by 20% to 30% within a few days. Therefore, regular cleaning of the solar panel surface is a necessary measure to ensure a stable power supply for intersection sentinels.

[0004] The existing solar panel angle adjustment function and surface cleaning function of the intersection sentry are implemented by independent subsystems, which has the following shortcomings: (1) Angle adjustment and surface cleaning require separate drive sources and transmission mechanisms, which are complex in structure, occupy a large space and have high manufacturing costs; (2) There is a lack of collaborative working relationship between the two functional subsystems. The cleaning action cannot be triggered synchronously during the angle adjustment process. The cleaning task needs to be arranged separately in terms of time and power, which increases the system energy consumption and control complexity; (3) Due to the lack of timely cleaning, the accumulation of dirt on the surface of the solar panel leads to insufficient power supply, which in turn affects the normal operation of the intersection sentry in continuous rainy weather, reducing the reliability and service life of the equipment.

[0005] To address the shortcomings of the existing technologies, this invention provides a level crossing safety warning system integrating radar and audible and visual warning units. It aims to simultaneously achieve angle adjustment and surface cleaning of solar panels using a single drive source. While adjusting the solar panel's orientation to track the sun's position, a cleaning brush simultaneously and repeatedly brushes the surface of the solar panel, promptly removing surface contaminants. This achieves "dual-purpose drive" without adding an additional power source, effectively ensuring the continuous and efficient power generation of the solar panels and the long-term stable operation of the intersection sentry.

This facilitates automatic brushing of the surface of the solar panel when adjusting its orientation, preventing dust and impurities from adhering to its surface and affecting the use of the solar panel; 2. By setting up the installation mechanism, removing the bolts, and rotating the rotating rod, the cleaning brush can be directly moved out of the installation slot, and the solar panel can be directly moved out of the connection slot. When installing the solar panel and cleaning brush, place the solar panel into the inner wall of the connection slot. At this time, the locking block moves into the locking slot, and the cleaning brush is connected into the installation slot. Then, rotate the rotating rod to a horizontal position and fix the rotating rod with bolts. At the same time, the roller contacts the horizontal plate, and the locking block cannot move out of the locking slot, thus automatically fixing the solar panel. This facilitates the quick disassembly and replacement of the solar panel and cleaning brush, making maintenance and replacement of the solar panel and cleaning brush convenient.

The position of the solar panel 7 is adjusted by an adjustment mechanism 8. The adjustment mechanism 8 includes a fixed column 801, which is fixedly connected to the top of the body 1. A motor 802 is installed on one side of the fixed column 801 at the top of the body 1. A first spur gear 803 is connected to the output end of the motor 802. A rotating cylinder 805 is rotatably connected to the outer wall of the fixed column 801. A gear ring 804 is fixedly connected to the outer wall of the rotating cylinder 805. The first spur gear 803 contacts the gear ring 804. A connecting frame 806 is fixedly connected to the top of the rotating cylinder 805. A connecting rod is fixedly connected to the top of the connecting frame 806. The solar panel 7 is mounted on the connecting seat 807 via the mounting mechanism 9. The adjusting mechanism 8 also includes a second spur gear 808, which is fixedly connected to the top of the fixed column 801. A third spur gear 809 is rotatably connected to the outer wall of the second spur gear 808 inside the rotating cylinder 805. A connecting shaft 810 is fixedly connected to the top of the third spur gear 809. A first bevel gear 811 is fixedly connected to the top of the connecting shaft 810. A second bevel gear 812 is rotatably connected to the outer wall of the first bevel gear 811 inside the connecting frame 806. A worm gear 813 is fixedly connected to one end of the second bevel gear 812. A worm wheel 814 is rotatably connected to the outer wall of the worm gear 813 inside the connecting frame 806.

A movable frame 817 is slidably connected to the inner wall of the movable groove 816. A cleaning brush 818 is installed on the movable frame 817.

[0023] In this embodiment: when adjusting the angle of the solar panel 7, the motor 802 is started. The motor 802 drives the first spur gear 803 to rotate. The rotation of the first spur gear 803 drives the gear ring 804 to rotate. The rotation of the gear ring 804 drives the rotating cylinder 805 to rotate. The rotation of the rotating cylinder 805 drives the connecting frame 806 to rotate. The rotation of the connecting frame 806 drives the connecting seat 807 to rotate. The rotation of the connecting seat 807 drives the solar panel 7 to rotate synchronously, thereby adjusting the angle of the solar panel 7 so that the solar panel 7 can adjust its orientation according to the position of the sun. When the rotating cylinder 805 rotates, the fixed column 801 rotates relative to the rotating cylinder 805. The rotation of the fixed column 801 drives the second spur gear 808 to rotate, which in turn drives the third spur gear 809 to rotate. The rotation of the third spur gear 809 drives the connecting shaft 810 to rotate, which in turn drives the first bevel gear 811 to rotate. The rotation of the first bevel gear 811 drives the second bevel gear 812 to rotate, which in turn drives the worm gear 813 to rotate. The worm gear 814 is driven to rotate, which in turn drives the reciprocating screw 815 to rotate. The reciprocating screw 815 then drives the movable frame 817 to move. The movable frame 817 moves back and forth along the movable groove 816. The movement of the movable frame 817 drives the cleaning brush 818 to move as well. The cleaning brush 818 then brushes the surface of the solar panel 7, which is convenient for automatically brushing the surface of the solar panel 7 when adjusting its orientation, thus preventing dust and impurities from adhering to its surface and affecting the use of the solar panel 7.

[0024] Please refer to this carefully. Figures 5 to 7 The installation mechanism 9 includes a rotating rod 901, which is rotatably connected to the top of the movable frame 817. The bottom end of the rotating rod 901 has a mounting groove 902. A cleaning brush 818 is slidably connected to the inner wall of the mounting groove 902. The top of the rotating rod 901 has a through hole 903. The top of the movable frame 817 has a threaded hole 904 corresponding to the through hole 903. A bolt 905 is threadedly connected to the inner wall of the threaded hole 904. The top of the connecting seat 807 has a connecting groove 906, and the solar panel 7 is slidably connected to the connecting groove 906. On the inner wall of 06, a slot 907 is provided on one side of the solar panel 7. A locking block 908 extending into the inner cavity of the connecting seat 807 is slidably connected inside. A connecting rod 909 is rotatably connected to the outer wall of the locking block 908. A horizontal plate 910 is rotatably connected to the outer wall of the connecting rod 909. The horizontal plate 910 is slidably connected inside the connecting seat 807 and extends to the top of the connecting seat 807. A spring 911 is connected between the horizontal plate 910 and the connecting seat 807. A roller 912 is installed at the bottom end of the rotating rod 901 on one side of the mounting groove 902.

[0025] In this embodiment: When installing the cleaning brush 818, the cleaning brush 818 is inserted into the inner wall of the mounting groove 902. Then, the rotating rod 901 is rotated to a horizontal position, aligning the through hole 903 with the threaded hole 904. The bolt 905 is passed through the through hole 903 and connected into the threaded hole 904 to fix the rotating rod 901. While the rotating rod 901 is fixed, the cleaning brush 818 contacts the surface of the solar panel 7, and the roller 912 contacts the top of the horizontal plate 910. When the locking block 908 is displaced out of the inner cavity of the connecting groove 906, the displacement of the locking block 908 drives the horizontal plate 910 to move through the connecting rod 909. The top of the horizontal plate 910 moves out of the connecting seat 807, compressing the spring 911. When disassembling, replacing, or maintaining the solar panel 7 and cleaning brush 818, remove bolt 905 to release the fixing of rotating rod 901. Rotate rotating rod 901, and the cleaning brush 818 can be directly removed from the mounting slot 902. Roller 912 separates from horizontal plate 910, allowing the solar panel 7 to be directly moved out of connecting slot 906. When installing the solar panel 7 and cleaning brush 818, place the solar panel 7 into the inner wall of connecting slot 906. At this time, locking block 908 moves into locking slot 907, allowing the cleaning brush 818 to be moved out of the mounting slot 906. 18 is connected into the mounting slot 902. Then, the rotating rod 901 is rotated to a horizontal position. The rotating rod 901 is fixed by the bolt 905. At the same time, the roller 912 contacts the horizontal plate 910, and the horizontal plate 910 cannot move upward. This prevents the locking block 908 from moving out of the slot 907, thereby automatically fixing the solar panel 7. This facilitates the quick disassembly and replacement of the solar panel 7 and the cleaning brush 818, making it convenient for maintenance and replacement of the solar panel 7 and the cleaning brush 818.
