Abstract
Description
Technical Field
[0001] This application relates to the field of ground marking technology, and in particular to a luminous marking device for ground use. Background Technology
[0002] Traditional ground signs are mostly made of metal. Although they have good visibility during the day, their recognizability is greatly reduced at night or in low-light environments, which can easily lead to safety accidents such as accidentally digging gas lines or colliding with facilities. Therefore, the market urgently needs a ground sign device that can automatically emit light at night and improve recognizability. Utility Model Content
[0003] The problem this application aims to solve is that while traditional ground signs have good visibility during the day, their recognizability is greatly reduced at night or in low-light environments, which can easily lead to accidental digging of gas lines or collisions with facilities.
[0004] To address the aforementioned technical problems, this application provides a ground-based luminous marking device. The device comprises a base with internal grooves for accommodating and securing various components; luminaires symmetrically arranged within the grooves, each containing an LED light source for emitting light upon receiving a control signal; an ultrasonic sensor integrated within the luminaire for sending a sensing signal to a controller when a person or object passes over the base; a battery located at the bottom of the groove for storing electrical energy converted from photovoltaic panels and providing power to the luminaires and controller when needed; and a controller located in the center of the groove for receiving the sensing signal from the ultrasonic sensor and triggering the luminaires to emit light. The battery is electrically connected to the luminaires and controller via cables, forming a complete circuit system.
[0005] Because the marking device of this application is designed with a base, lamps, ultrasonic sensors, batteries and controllers, it can automatically emit light to remind people after the surface is covered by integrating components such as photovoltaic panels, lamps, ultrasonic sensors and batteries. This effectively improves the visibility in the nighttime environment and solves the problem that although traditional ground signs have good visibility during the day, their visibility is greatly reduced at night or in low light conditions, which can easily lead to accidental digging of gas lines or collisions with facilities.

[0012] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example
[0013] This application relates to a ground-based luminous marking device, such as... Figure 1-5 As shown, the marking device includes a base 4, a photovoltaic panel 7, a lamp 6, a battery 10, a controller 9, and a cover plate 1. The base 4 is made of engineering plastic, which has good weather resistance and impact resistance. A cross-shaped groove 8 is formed inside the base 4 to accommodate and fix the various components. The photovoltaic panel 7 is arranged in the middle of the groove 8 to convert sunlight into electrical energy to provide power for the entire device. The lamps 6 are symmetrically arranged on both sides of the photovoltaic panel 7 and have built-in LED light sources to emit light when a control signal is received. The lamps 6 also integrate ultrasonic sensors to detect whether a person or object is passing over the top of the base 4. When a person or object passes over the top of the base 4, the ultrasonic sensor can identify the obstacle and send a signal. The sensor signal is sent to the controller 9. The battery 10 is located at the bottom of the groove 8 to store the electrical energy converted by the photovoltaic panel 7 and to provide power to the lamp 6 and the controller 9 when needed. The controller 9 is located in the middle of the groove 8 to receive the sensor signal from the ultrasonic sensor and trigger the lamp 6 to light up. The battery 10 is electrically connected to the photovoltaic panel 7, the lamp 6 and the controller 9 through cables to form a complete circuit system. The cover plate 1 is located on the upper part of the base 4 to protect the internal components from external environmental damage. The cover plate 1 is connected to the base 4 around the perimeter by bolts 5 to ensure a firm connection. The upper part of the bolts 5 is provided with rubber plugs 3 to cover the heads of the bolts 5, thereby preventing the bolts 5 from getting dirty and affecting the appearance.
[0014] During the day, the photovoltaic panel 7 converts sunlight into electrical energy and stores it in the battery 10. If a person or object passes over the base 4, the ultrasonic sensor will detect the obstacle and send a sensing signal to the controller 9. After receiving the signal, the controller 9 will trigger the lamp 6 to light up, thus providing a conspicuous reminder, especially in the dim environment at night, where the reminder effect is better.
[0015] By integrating components such as photovoltaic panel 7, lamp 6, and ultrasonic sensor, the device achieves automatic nighttime illumination and alert functions, greatly improving visibility in nighttime environments. The base 4, made of engineering plastic, has excellent weather resistance and impact resistance, enabling it to adapt to various harsh environments. The design of the transparent cover 1 and rubber plug 3 protects the internal components, prevents damage to the bolts 5, and maintains the aesthetics of the device. Compared to traditional metal signs, this invention offers higher safety and practicality, effectively preventing safety accidents such as accidental excavation of gas lines.
[0016] To further enhance the luminous effect, the ground luminous marking device of the present invention has a special design on the surface of the cover plate 1. Specifically, the surface of the cover plate 1 is arranged with outward protruding protrusions 2 at intervals. These protrusions 2 not only increase the surface roughness of the cover plate 1, but also cleverly utilize optical principles to diffuse the light source generated by the lamp 6.
[0017] When the lamp 6 is triggered to emit light by the controller 9, the light source first illuminates the inner surface of the cover plate 1. Since the surface of the cover plate 1 is arranged with synapses 2 at intervals, these synapses 2 are like countless miniature optical lenses, refracting and scattering the light. In this way, the originally concentrated light is diffused to a larger range, thereby increasing the illumination range and making the signage device more conspicuous at night or in low-light environments.
[0018] The design of the synapses 2 on the surface of the cover plate 1 effectively diffuses the light source generated by the lamp 6, increasing the illumination range and making the signage device clearly identifiable at a greater distance. The design of the synapses 2 not only increases the illumination range but also enhances the three-dimensionality and layering of the signage device, making it more visually appealing. This synapse 2 design is suitable for cover plates 1 of various shapes and sizes and can be flexibly applied to different types of ground signage devices, making it widely applicable.
[0019] When using the device, first determine its installation location, ensuring it receives sufficient sunlight to guarantee normal power generation from the photovoltaic panel 7. Use appropriate tools to dig a groove in the ground that matches the shape of the base 4, ensuring the base 4 can be securely embedded. Place the base 4 into the groove and adjust it to a horizontal position. Use bolts 5 to tightly connect the transparent cover 1 to the base 4, ensuring the internal components are protected from external environmental damage. Install rubber plugs 3 on top of the bolts 5 to cover their heads and maintain the aesthetics of the device. Regularly check the surface of the photovoltaic panel 7 for cleanliness; if dust or dirt is present, clean it promptly to ensure the power generation efficiency of the photovoltaic panel 7. Also check the lights 6, ultrasonic sensors, and battery 10, etc. Check whether the component connection lines are loose or damaged. If any abnormality is found, repair or replace them in time. Regularly check whether the transparent cover plate 1 and the contact 2 are intact. If there is any damage or wear, replace them in time to ensure the luminous effect and safety of the sign device. When a person or object passes by, the sign device will automatically light up to remind you without manual intervention. If you need to turn off the luminous function, you can manually set it through the controller 9. For some special environments, such as construction sites and mining areas, the sign device may be subjected to greater impact or vibration. In this case, consider taking additional fixing measures to ensure the stability of the sign device. In extreme weather conditions, such as heavy rain and heavy snow, the working status of the sign device should be checked regularly to ensure its normal operation.
