DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-4 The utility model is described in further detail.

[0028] The utility model discloses a self-luminous highway guardrail structure.

[0029] Reference Figure 1 and Figure 2 A self-luminous highway guardrail structure includes a guardrail plate 1, a connecting component 2 and a coating component 3; the guardrail plate 1 is arranged on the side of the highway through the connecting component 2, and the coating component 3 includes an energy storage luminescent layer 31, and the energy storage luminescent layer 31 is coated on the side of the guardrail plate 1 facing the road surface; at night or in a dim environment, the energy storage luminescent layer 31 emits light by itself, thereby improving the visibility of the guardrail plate 1, making it easier for the driver to identify the position of the guardrail plate 1, and then accurately judge the direction of the road, reducing the incidence of traffic accidents.

[0030] In the utility model, the energy storage luminescent layer 31 is prepared by using energy storage luminescent powder with zinc sulfide and rare earth element europium as luminescent agents, wherein the molar mass fraction of europium doped in zinc sulfide is 0.015-0.016 g / mol, and the molar mass fraction of fluorine doped is 0.011-0.012 g / mol. When the energy storage luminescent layer 31 is exposed to light, it absorbs light energy and converts it into an excited state. At this time, the electrons are in an unstable state and will try to return to a more stable low energy level. However, when the light continues to shine, the electrons are constantly excited to a high energy level and lack sufficient time to return to a low energy level through radiation transition (i.e., luminescence). When the environment darkens or the light source disappears, the external excitation stops, and the electrons previously accumulated at the high energy level begin to return to the low energy level through radiation transition, thereby achieving the technical effect of self-luminescence of the energy storage luminescent layer 31 at night or in a dim environment.

[0031] Reference Figure 1 and Figure 2 In order to further improve the light energy utilization rate and the luminous effect of the energy storage luminescent layer 31, a light energy absorption conversion layer 32 is arranged between the guardrail plate 1 and the energy storage luminescent layer 31. The light energy absorption conversion layer 32 of the utility model is prepared by modifying barium titanate nanoparticles with a new photosensitive material, so as to realize the absorption of light in a wider spectral range. When excited by light, the barium titanate nanoparticles generate photoelectrons and holes (i.e., photogenerated charges). The photogenerated electrons and holes are separated in space. The separated photoelectrons and holes are transferred to the energy storage luminescent layer 31 through a specific charge transfer mechanism. In the energy storage luminescent layer 31, the photogenerated electrons and holes interact with zinc sulfide and the rare earth element europium. The wide bandgap characteristics of zinc sulfide enable it to accommodate photoelectrons and holes. The rare earth element, as the luminescent center, absorbs the energy of the photoelectrons and holes and transitions to a high energy level. When the europium ions return from the high energy level to the low energy level, photons are released, thereby producing a bright and lasting luminescence phenomenon.

[0032] Reference Figure 1 and Figure 2In order to further improve the warning effect of the guardrail 1, the energy storage luminous layer 31 is coated with a reflective reinforcement layer 34. The reflective reinforcement layer 34 of the utility model is prepared by a transparent polyurethane coating containing reflective glass beads. The particle size of the reflective glass beads is 0.1-0.2mm. Specifically, the particle size of the reflective glass beads can be set to 0.1mm, 0.2mm, or 0.15mm, as long as the reflective glass beads capture and reflect external light to form a strong reflective effect; during the day or in an environment with sufficient light, the energy storage luminous layer 31 absorbs and stores light energy to reserve energy for night or dim environments. At night or when the ambient light weakens, the energy in the energy storage luminous layer 31 begins to be gradually released and emits light. At this time, the reflective reinforcement layer 34 remains transparent, allowing the light of the energy storage luminous layer 31 to pass through, and when irradiated by external light, the reflective glass beads capture and reflect external light to form a strong reflective effect, so that the guardrail 1 presents an obvious reflective effect at night or in a dim environment, greatly improving the visibility and safety of the guardrail 1.

[0033] Reference Figure 2 In order to improve the use effect and service life of the coating component 3, a surface light-transmitting protective layer 35 is coated on the reflective enhancement layer 34. The surface light-transmitting protective layer 35 of the utility model is set as a transparent topcoat, so that the light emitted by the reflective enhancement layer 34 and the energy storage luminescent layer 31 can penetrate the surface light-transmitting protective layer 35. At the same time, the transparent topcoat forms an outer layer of protection to resist the erosion of stains, dust, moisture, etc. in the external environment, thereby improving the wear resistance of the coating component 3.

[0034] Reference Figure 1 and Figure 2 In order to strengthen the adhesion between the coating component 3 and the guardrail board 1, a base adhesion layer 33 is arranged between the guardrail board 1 and the energy storage luminescent layer 31. The base adhesion layer 33 of the utility model is prepared from epoxy resin, and the epoxy resin is doped with nano-scale silane coupling agent to improve the compatibility and adhesion between the epoxy resin and different materials, and enhance the interface bonding strength between the base adhesion layer 33 and the guardrail board 1 and between the base adhesion layer 33 and the light energy absorption conversion layer 32.

[0035] Reference Figure 1 and Figure 2In order to further improve the bonding strength between the base adhesion layer 33 and the light energy absorption conversion layer 32, a layer anchor is also provided. One end of the layer anchor extends to a section of the base adhesion layer 33 away from the guardrail plate 1, and the other end extends to a section of the light energy absorption conversion layer 32 close to the guardrail plate 1, so as to improve the damping performance of the light energy absorption conversion layer 32 and reduce the possibility of relative sliding between the light energy absorption conversion layer 32 and the base adhesion layer 33. The middle layer anchor of the utility model is set to calcium carbonate particles. The particle size of the calcium carbonate particles is 0.3-0.4mm. Specifically, the particle size of the calcium carbonate particles can be set to 0.3mm, 0.4mm, or 0.35mm. As long as the filling effect of the calcium carbonate particles makes the light energy absorption conversion layer 32 and the base adhesion layer 33 tighter and more stable, at the same time, the calcium carbonate particle material is not easy to react chemically with other materials, and remains stable for a long time, thereby realizing a stable connection between the light energy absorption conversion layer 32 and the base adhesion layer 33.

[0036] Reference Figure 3 and Figure 4 The connecting component 2 includes a connecting plate 21 and a column 22, and the column 22 is connected to the guardrail plate 1 through the connecting plate 21. The connecting component 2 is provided with multiple groups, and the multiple groups of connecting components 2 are arranged along the length extension direction of the guardrail plate 1. In the utility model, the connecting component 2 can be set to two groups, three groups, four groups, or five groups, as long as the guardrail plate 1 is connected through the connecting component 2; a reinforcement plate 4 is arranged between two adjacent groups of connecting components 2, and the reinforcement plate 4 is connected to the guardrail plate 1.

[0037] Reference Figure 1 and Figure 4 In order to further improve the visibility of the guardrail board 1 at night or in a dim environment, and to ensure that the guardrail board 1 always maintains sufficient brightness when the self-luminous effect of the guardrail board 1 weakens due to time or environmental factors, a lighting assembly 5 is provided. The lighting assembly 5 includes a lighting lamp 51, a light-controlled switch 52, a solar photovoltaic panel 53 and an energy storage module 54. The lighting lamp 51 is installed directly below the guardrail board 1, and the light of the lighting lamp is projected on the side of the guardrail board 1 facing the road surface. The solar photovoltaic panel 53 is installed above the reinforcement plate 4, and the solar photovoltaic panel 53 is connected to the lighting lamp 51 through the energy storage module 54. 1, the light-controlled switch 52 is installed on the illuminating lamp 51, and the output end of the light-controlled switch 52 is electrically connected to the input end of the illuminating lamp 51. The light-controlled switch 52 automatically senses light changes. At night or when the ambient light becomes dim and reaches a preset threshold, the light-controlled switch 52 starts the illuminating lamp 51 to work, and the illuminating lamp 51 illuminates the guardrail board 1, further improving the visibility of the guardrail board 1 at night or in a dim environment. In addition, in addition to being powered by the solar photovoltaic panel 53, the illuminating lamp 51 is also provided with a backup power supply to ensure the normal use of the illuminating lamp 51 under extreme conditions such as long-term lack of light.
