Description

Technical Field

[0001] This utility model belongs to the technical field of induction sound and light alarm devices, specifically relating to an active sound and light protection alarm device for guardrails. Background Technology

[0002] In various locations requiring guardrails, such as construction sites, areas around public facilities, and along main roads, guardrails play a vital safety role, effectively preventing people or objects from entering dangerous areas and avoiding accidents. However, relying solely on the physical barrier function of guardrails is insufficient to guarantee safety in some situations. For example, if someone attempts to climb over a guardrail and is not detected and stopped in time, it could lead to a serious accident. Therefore, installing alarm devices on guardrails has become an important safety measure. Currently, most existing sound and light alarm devices for guardrails on the market use solar power. Their basic structure generally includes a main body, a solar panel, an alarm, and a human body sensor. For example, the existing patent with publication number CN209216231U discloses a "solar-powered sensor alarm device, including a housing, the housing..." The device contains a battery, a main control module, and a voice playback module. A human body sensor module is located at the top of the enclosure, and a solar panel is connected to the enclosure via a bracket. The main control module is connected to both the voice playback module and the human body sensor module, and the solar panel is connected to the battery. This indicates that the application describes a common solar-powered sensor alarm. To increase the detection range, some alarm devices also add a human body sensor on each side, effectively expanding the detection range so that even when someone climbs over a railing from the side, the device can still be effectively detected and trigger an alarm. Furthermore, the solar panel bracket is designed as a split type and equipped with a motor, a PLC motion controller, and a light-tracking sensor. This allows the operator to control the motor via the PLC motion controller to rotate the solar panel at the top, ensuring the solar panel faces the sun more effectively and generates more electricity, thus improving solar energy collection efficiency.

[0003] However, in practical use, existing solar-powered sensor alarms generally require multiple bolts and other fixing structures to be installed on guardrails. This traditional installation method reduces the ease of installation, making it difficult to quickly assemble the device in the early stages and reducing construction efficiency. Furthermore, when the device malfunctions and needs to be disassembled for inspection and maintenance, it takes a lot of time, further reducing the ease of disassembly and assembly. As a result, both the ease of initial assembly and the ease of subsequent maintenance of the device are low. Therefore, this utility model proposes an active sound and light protection alarm device for guardrails. Utility Model Content

[0024] Side human body sensor 5: Side human body sensor 5 is provided on both sides of the main body 1. The side human body sensor 5 has the same structure and function as the front human body sensor 3. It can detect the areas on both sides of the main body 1 on the basis of the original detection range, so that when people climb over the railing from the side of the main body 1, they can still be effectively detected. The side human body sensor 5 and the front human body sensor 3 are commercially available mature products, such as the human body sensor of the HZG-PIR series. The above structure is all existing technology. For the specific structural principle, please refer to the existing patent with publication number CN209216231U. It will not be elaborated here.

[0025] A motor 62, model MS1H3-18C15CD-T334R, is fixedly installed on the inner side of the top of the U-shaped bracket 6. The output end of the motor 62 extends through to the top of the U-shaped bracket 6 and is fitted with a rotating top bracket 63. A fixed back bracket 64 is fixed to the top of the rotating top bracket 63 and is attached to the back of the solar panel 7. A PLC motion controller 61, connected to the motor 62 via a signal line, is also located inside the U-shaped bracket 6. A light-tracking sensor, connected to the PLC motion controller 61, is also installed on the solar panel 7. This light-tracking sensor is existing technology. For the specific structural principle, please refer to the existing patents with publication numbers CN103197690B and CN101976084B, which will not be elaborated here. The operator can control the operation of the motor 62 through the light tracking sensor and the PLC motion controller 61, so that the motor 62 drives the rotating top frame 63 to rotate the solar panel 7 on the top of the main body 1, thereby enabling the solar panel 7 to better face the sun to ensure power generation and improve the solar energy collection efficiency. The PLC motion controller 61 adopts a commercially available mature product, such as the Mitsubishi FX3G-32MTPLC controller product.

[0026] In this embodiment, preferably, the mounting bracket 64 is fixed to the back of the solar panel 7 by a plurality of bolts.

[0027] A rectangular socket 11 is welded and fixed to the bottom surface of the main body 1, and a rectangular slot 81 for inserting the rectangular socket 11 is provided at the top of the guardrail 8. A disassembly and assembly structure is provided between the main body 1 and the guardrail 8. The disassembly and assembly structure includes a transverse pin 95 that passes through both the rectangular socket 11 and the guardrail 8, allowing the guardrail 8 and the rectangular socket 11 to be directly inserted together. The disassembly and assembly structure also includes two limiting baffles 92 that are rotatably installed at the bottom of the main body 1, and the inner side of the limiting baffles 92 is fixed with a limiter to block and limit the transverse pin 95. The stop block 93 can block and limit the transverse pin 95 after it passes through, preventing the transverse pin 95 from falling off and ensuring the connection stability between the main body 1 and the guardrail 8. The surface of the rectangular socket 11 has a transverse through hole 12 for the transverse pin 95 to pass through. The two sides of the guardrail 8 have side insertion holes 82 for the transverse pin 95 to be inserted. The bottom surface of the main body 1 is fixed with a rotating seat 91 relative to the top of each limiting baffle 92, and the top of the limiting baffle 92 is rotatably connected to the rotating seat 91 through a rotating shaft, so that the limiting baffle... The limit baffle 92 can rotate smoothly at the bottom of the main body 1, facilitating the subsequent rotation of the limit baffle 92 to a horizontal position to release the obstruction of the transverse pin 95. The disassembly and assembly structure also includes a wing bolt 94 passing through the bottom end of the limit baffle 92, and threaded grooves 96 are provided on both sides of the guardrail 8 for the wing bolt 94 to screw into. The threaded end of the wing bolt 94 is screwed into the threaded groove 96, and the limit baffle 92 can be fixed by the wing bolt 94 to ensure the stable vertical state of the limit baffle 92, thereby ensuring the connection between the limit baffle 92 and the limit... The stop block 93 provides stability to the transverse pin 95. When it is necessary to separate the main body 1 from the guardrail 8, the operator only needs to rotate the wing bolt 94 counterclockwise so that the threaded end of the wing bolt 94 is unscrewed from the thread groove 96. This allows the limit plate 92 to be rotated to a horizontal position, and the limit plate 92 and the stop block 93 no longer obstruct the transverse pin 95. At this time, the transverse pin 95 can be pulled out, and the main body 1 and the guardrail 8 can be quickly separated, ensuring the ease of disassembly and assembly of the entire device.

[0028] In this embodiment, preferably, the bottom surface of the limiting baffle 92 is provided with a bolt hole for the butterfly bolt 94 to pass through.

[0029] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
