[0003] Referring to Chinese Patent Publication No. CN214193991U, with the publication date of the publication date being September 14, 2021, a self-luminous pavement structure based on exposed aggregate process is disclosed. This utility model can drain the sewage that seeps into the pavement structure, avoiding water accumulation on the pavement during rain and affecting normal vehicle traffic and pedestrian passage.

[0004] Referring to Chinese Patent Publication No. CN214831609U, with the publication date of November 23, 2021, a non-slip energy storage luminous pavement structure is disclosed. This non-slip energy storage luminous pavement structure, by setting an energy storage luminous layer and a solar panel, can firstly absorb solar energy through the solar panel and transmit it to the storage battery for storage, and secondly, the solar energy absorbed by the energy storage luminous layer can be emitted at night after energy storage, and a portion of the energy can be converted by an energy converter, and then transmitted to the storage battery through a wire for energy storage. Thus, it can store energy in multiple ways, improving the lighting time and safety factor.

[0005] However, during the use of the above-mentioned utility model, the indicator light is not easy to disassemble. When it rains, rainwater can easily enter the lower side of the indicator light, which can easily damage the circuit and is not conducive to long-term use. Therefore, there is still room for further improvement.

[0006] Therefore, we propose a luminous pavement structure with energy storage function to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this utility model is to provide a luminous road surface structure with energy storage function, in order to solve the problem that the indicator lights are inconvenient to disassemble during use, and when encountering rainy weather, rainwater can easily enter the lower side of the indicator lights, which can easily damage the circuit and is not conducive to long-term use. Therefore, there is still room for further improvement.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a luminous pavement structure with energy storage function, comprising:

[0009] Plain soil layer, on the upper side of which a crushed stone cushion layer is laid, and on the upper side of the crushed stone cushion layer a graded layer is laid;

[0010] Also includes:

[0011] A permeable concrete layer, wherein an energy storage mechanism for power generation is provided inside the permeable concrete layer, and the permeable concrete layer is laid on the upper side of the graded layer.

[0012] A permeable plastic layer is provided, the interior of which is equipped with an illumination mechanism for emitting light, and the permeable plastic layer is laid on the upper side of the permeable concrete layer.

[0017] Preferably, a connecting pipe is provided on the lower side of the lighting lamp, and a T-shaped rubber ring is provided on the outer side of the connecting pipe, and the T-shaped rubber ring is slidably connected to the mounting pipe.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the luminous road surface structure with energy storage function can use the temperature difference to charge the battery, thereby achieving the function of energy storage and reducing the dependence on energy. When the lighting lamp and the connecting pipe are inserted into the installation pipe together, the T-shaped rubber ring will bend upward, thereby sealing the side of the connecting pipe with the inner wall of the installation pipe, preventing rainwater from entering the bottom of the lighting lamp, which is beneficial for long-term use.

[0019] 1. It is equipped with a graded layer, a permeable concrete layer and a permeable plastic layer. The permeable plastic layer is laid on top, which can increase the friction and also protect the thermoelectric generator.

[0020] 2. It is equipped with a thermoelectric generator, a storage battery and a first opening. The thermoelectric generator can use the temperature difference to charge the storage battery, thereby achieving the function of energy storage and reducing dependence on energy.

[0021] 3. It is equipped with a lighting lamp, a connecting pipe, and a T-shaped rubber ring. The connecting pipe has a T-shaped rubber ring on the outside. When the lighting lamp and the connecting pipe are inserted into the mounting pipe together, the T-shaped rubber ring will bend upward, thereby sealing the side of the connecting pipe with the inner wall of the mounting pipe, preventing rainwater from entering under the lighting lamp, which is beneficial for long-term use.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 As shown, this utility model provides a technical solution: a luminous pavement structure with energy storage function, comprising: a soil layer 1, a crushed stone cushion layer 2, a graded layer 3, a permeable concrete layer 4, a permeable plastic layer 5, an installation pipe 6, a thermoelectric generator 41, a battery 42, a first opening 43, a reflective layer 51, a second opening 52, a lighting lamp 61, a connecting pipe 62, and a T-shaped rubber ring 63.

[0029] In the existing utility model, the indicator light is inconvenient to disassemble during use. When it rains, rainwater can easily enter the lower side of the indicator light, which can easily damage the circuit and is not conducive to long-term use. Therefore, there is still room for further improvement.

[0030] like Figure 1 and Figure 2 As shown, during the paving process, a crushed stone cushion layer 2, a graded layer 3, a permeable concrete layer 4, and a permeable plastic layer 5 are laid sequentially on top of the subgrade layer 1. The graded layer 3 is composed of graded ceramsite (particle size 5-10mm) and basalt fiber (admixture 1.5%). A reflective layer 51 is set on the upper part of the permeable plastic layer 5, and fluorescent ceramic particles are added inside the reflective layer 51. The excitation wavelength of the fluorescent ceramic particles is 400-450nm, and the luminescence duration is ≥8 hours, thereby achieving self-luminescence of the road surface in rainy nights, and the brightness reaches ≥15cd / m², thereby improving visibility by 30%.

[0031] In addition, the surface roughness of the reflective layer 51 can be optimized to Ra=0.8-1.2μm, and the wet friction coefficient is ≥0.65, which is far greater than the 0.55 required by GB / T35465.3-2017, reducing the risk of slipping and thus enhancing nighttime safety.

[0032] like Figure 1 and Figure 2 As shown, a thermoelectric generator 41 is added inside the permeable concrete layer 4. The thermoelectric generator 41 generates electricity by utilizing the large thermoelectric potential of semiconductors. It is a new type of electronic device with the characteristics of no noise, no pollution, and high energy conversion efficiency. It can realize energy recovery coupling. In addition, a storage battery 42 is installed inside the permeable concrete layer 4. The electricity generated by the thermoelectric generator 41 is transferred to the storage battery 42 and stored, which has the effect of energy storage. Then, it supplies power to the lighting lamp 61 to realize lighting, so that the road surface can achieve the effect of light.

[0033] It should be noted that in non-heavy-load areas such as sidewalks, the thermoelectric generator 41 model is TEG, with a size of 50mm×50mm and a conversion efficiency of 8%. It generates electricity when the temperature difference between rainwater and the pavement layer is ≥5℃, and the daily power generation per square meter is ≥0.2kWh, which can drive surrounding LED lighting or sensors.

[0034] like Figure 1 , Figure 3 and Figure 4As shown, during use, the mounting tube 6 is inserted into the second opening 52 and the first opening 43, and then the connecting tube 62 on the lower side of the lighting lamp 61 is located inside the mounting tube 6. Since the outer diameter of the T-shaped rubber ring 63 on the outside of the connecting tube 62 is larger than the inner diameter of the mounting tube 6, the T-shaped rubber ring 63 will deform after being inserted into the mounting tube 6. When encountering rainy or snowy weather, if rainwater enters the inside of the mounting tube 6, the rainwater will be isolated on the upper side of the T-shaped rubber ring 63, preventing rainwater from contacting the wiring of the lighting lamp 61, thus providing a protective function.

[0035] like Figure 3 As shown, a sealing plug is provided on the lower side of the mounting pipe 6. When the wire of the lighting lamp 61 passes through the sealing plug, a sealed space is formed, and rainwater will not enter the mounting pipe 6 from below.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
