Description

TECHNICAL FIELD

[0001] The utility model relates to road traffic engineering technical field especially is related to a road surface marking device. BACKGROUND

[0002] In municipal road traffic engineering, the road surface marking of the driving road is usually formed by hot-melt painting with paint containing reflective components. When the vehicle drives on the road surface, the reflective material of the road surface marking of the driving road directly reflects the light to the driver's eyes through the air, so that the driver can adjust the driving position of the vehicle according to the relative position of the vehicle boundary and the road surface marking of the driving road and keep the vehicle in the specified lane for safe driving, thereby playing an important role in guiding the driver to drive the vehicle in the specified lane.

[0003] However, in areas with more rainfall and frequent rainfall, the traditional road surface marking line cannot completely realize the function of guiding the driving route. The reason is that the traditional road surface marking line cannot ensure that the road driving road boundary position information is effectively transmitted to the driver under normal rainfall conditions and normal road surface water accumulation. In areas with heavy rainfall and frequent rainfall, even under normal rainfall conditions, the road surface is prone to slight water accumulation. After the road surface is slightly waterlogged, the road surface marking line is submerged, and the reflected light of the road surface marking line will be refracted from the water to the air at a large incident angle. According to the principle of light path refraction when light is refracted from water to air, the reflected light of the road surface marking line will enter the air at a large refraction angle from the air-water interface, which means that the original reflected light will change the light propagation path and propagate at a smaller angle with the air-water interface. The driver's eyes close to the marking line cannot receive the reflected light of the road surface marking line in front of the eyes and cannot judge the distance between the vehicle and the boundary of the corresponding lane, and even when the water is shallow, total reflection will occur when the incident angle of the reflected light of the road surface marking line is too large to exceed the critical angle, so that the driver cannot receive the reflected light of the road surface marking line. Especially at night in rainy weather, the road surface marking line of the driving road will completely lose its function in most cases, so that the driver drives the vehicle completely by feeling, which is more likely to cause traffic accidents.

[0004] Using the traditional road surface marking line, in the case of poor vehicle driving vision and limited use of high beam, the road surface marking line cannot effectively guide the direction of the road in the distance, which is easy to cause fatigue driving. In the case of poor vision such as fog and overcast weather, the traditional road marking line cannot realize the function of guiding the road in the distance.

[0005] The traditional road marking line can only be used on the hardened road surface and cannot be applied to the sand road surface, and the use range is limited. The traditional road marking line needs to be hot-melt painted on the hardened road surface, and cannot be painted on the sand road surface, so the traditional road marking line is not applicable to the sand road surface. However, the sand road surface objectively exists, and has the characteristics of generally low road grade, narrow road, poor road line shape compared with the high-grade municipal road, and poor driving sight, and the sand road surface needs the road marking line to guide the vehicle driving lane position more than the high-grade municipal road. In addition, the traditional road marking line needs special equipment for maintenance on the hardened road surface, and the maintenance is inconvenient and takes a long time, which affects the road traffic.

[0039] Some embodiments of the utility model will be described in detail below in combination with the drawings. In the case of no conflict, the following examples and features in the examples can be combined with each other.

[0040] Example one

[0041] The conventional road surface marking line has the problems of being unable to effectively transmit the road edge line position information under the condition of normal rainfall and normal road surface water accumulation, being unable to effectively guide the direction of the far road section under the condition of poor vehicle driving sight and limited use of high beam, and limited use range and inconvenient maintenance.

[0042] Therefore, the utility model embodiment provides a road surface marking device, which comprises a shell 4, a roller 1 and a warning mark silk 9, the shell 4 is provided with a containing cavity, the roller 1 is arranged in the containing cavity, the roller 1 can rotate around its own axis, the warning mark silk 9 is arranged on the roller 1 in the circumferential direction, the top of the containing cavity is provided with a warning mark silk inlet and outlet 12 for the warning mark silk 9 to enter and exit, and the warning mark silk 9 is a high-elasticity nylon silk with fluorescence.

[0043] Please see Figure 1 In the road section where the pavement marking device is needed to be installed, the single pavement marking device is embedded at equal intervals and the ground elevation is ensured to be flush with the top surface of the shell 4. After the embedding is completed, the roller 1 is rotated so that the whole row of warning sign filaments 9 is completely stretched out from the warning sign filament exit 12. When a group of warning sign filaments 9 is worn out and damaged, the roller 1 is rotated to the appropriate position so that the old warning sign filaments 9 are recycled into the shell 4 and the new warning sign filaments 9 are stretched out from the warning sign filament exit 12 and continue to play the role of lane boundary guide.

[0044] Since the high-elasticity nylon filament with fluorescence is used as the warning sign filament 9, the problem that the information transmission mode of the traditional road marking line is easily affected by the road surface water is solved from the perspective of information transmission mode and increasing the recognition degree of the lane boundary reference. The high-elasticity nylon filament as the road boundary information sign makes the traditional two-dimensional plane marking line change into a three-dimensional marking line, which can still stand on the water surface under the condition of accumulated water, avoids the information transmission mode of refracted light transmission, and ensures that the road boundary information can be transmitted to the driver near the road marking line in time. At the same time, a large amount of light irradiation makes the warning sign filament 9 that swings continuously with the water flow continuously emit fluorescence, increases the dynamic recognition degree of the lane boundary position reference, and makes the road boundary information clearly transmitted to the vehicle driver, eliminating the interference of precipitation on information transmission.

[0045] The warning sign filament 9 solves the problem that the traditional pavement marking line cannot effectively guide the direction of the far road section from the visual principle, can relieve fatigue driving, and provides an intuitive and effective method for judging the road condition of the far road section. The warning sign filament 9 uses the principle that the dynamic light-emitting target is more easily recognized by the human eye than the static non-light-emitting target, actively emits fluorescence under poor light conditions, and swings with the air flow or water flow of the road surface, forms a long-distance, colored optical guide belt, actively prompts the vehicle to drive in the specified lane, and can relieve the driving fatigue of the driver. At the same time, on the road section with many curves and poor visibility, when the driver finds that the fluorescence brightness of the front warning sign filament 9 is very strong, it can be judged that there is a vehicle just passing through in the short distance in front, and the vehicle speed needs to be controlled, which assists the driver in judging the road condition in front.

[0046] The pavement marking device can set the road marking line on the sandy road surface and provide road guidance for the vehicle driving on the sandy road surface, and has a wide range of use. The pavement marking device does not need to use screws, rivets and other fasteners, and does not need to use special tools for installation and maintenance, which reduces the maintenance difficulty and is convenient to maintain. The warning sign filament 9 can freely swing and complete self-cleaning under the action of the air flow or water flow, and unless auxiliary cleaning is needed on the serious dust road section, the device can be swept by compressed air.

[0047] In an alternative mode of the embodiment, the warning flag filaments 9 have a single fluorescent color or multiple different fluorescent colors.

[0048] The warning flag filaments 9 can have a single fluorescent color or multiple different fluorescent colors according to the use scenario. The high-elasticity warning flag filaments 9 can stand in water and swing with the air flow and water flow. When multiple different fluorescent colors are used, the warning flag filaments 9 form a gradient fluorescent color guide belt, which is conducive to relieving driving fatigue.

[0049] In an alternative mode of the embodiment, the roller 1 is provided with a plurality of mounting holes 8 in the circumferential direction, and each mounting hole 8 is provided with a bundle of warning flag filaments 9.

[0050] Please refer to Figure 4 and Figure 5 , the surface of the roller 1 is provided with a plurality of mounting holes 8 in the circumferential direction, and each mounting hole 8 is provided with a bundle of warning flag filaments 9. After rotating the roller 1, the entire row of warning flag filaments 9 will be completely stretched out from the warning flag filament inlet and outlet 12.

[0051] In an alternative mode of the embodiment, the two ends of the roller 1 are provided with a plurality of manual poking holes 10 in the circumferential direction.

[0052] Please refer to Figure 5 , the two ends of the warning flag filament 9 mounting area in the middle of the roller 1 are each provided with a circle of manual poking holes 10, which can be poked by hand or compressed air to rotate the roller 1.

[0053] In an alternative mode of the embodiment, one side of the accommodating cavity is detachably provided with a movable supporting block 2, the movable supporting block 2 is provided with a first supporting shaft mounting hole 7, the side surface of the shell 4 is provided with a second supporting shaft mounting hole 6, and the two ends of the roller 1 are protrusively provided with supporting shafts 5, which are respectively arranged in the first supporting shaft mounting hole 7 and the second supporting shaft mounting hole 6.

[0054] Please refer to Figure 2 and Figure 3 , the two supporting shafts 5 are respectively arranged on the shell 4 and the movable supporting block 2, and the movable supporting block 2 enables the roller 1 to rotate around the line connecting the centers of the first supporting shaft mounting hole 7 and the second supporting shaft mounting hole 6.

[0055] Further, the movable supporting block 2 is a cuboid structure with a hole in the middle, and the hole penetrates the movable supporting block 2 in the thickness direction and forms the first supporting shaft mounting hole 7.

[0056] Please refer to Figure 7 , the diameter of the hole is equal to the diameter of the supporting shaft 5, and the thickness of the movable supporting block 2 is equal to the length of the supporting shaft 5.

[0057] In the alternative mode of the embodiment, the movable supporting block 2 and the side wall of the shell 4 form a cavity structure with a top opening, and the block-shaped anti-extraction pin 3 is arranged in the cavity structure.

[0058] Please refer to Figure 1 The block-shaped anti-extraction pin 3 is installed in the cavity structure between the movable supporting block 2 and the side wall of the shell 4, and can support the movable supporting block 2 to make the roller 1 rotate normally.

[0059] Further, please refer to Figure 6 The top of the block-shaped anti-extraction pin 3 is rotatably installed with a handle 13.

[0060] In the alternative mode of the embodiment, four anchor feet 11 are arranged at the four corners of the bottom of the shell 4, and the bottom surface of the anchor feet 11 is flush with the bottom surface of the shell 4.

[0061] Please refer to Figure 1 The four anchor feet 11 at the bottom of the shell 4 are used to be pulled out when the pavement marking device is buried in the pavement. When the device is installed on a hardened pavement or a sandy soil pavement, it can be directly backfilled or poured to the pavement to be consistent with the upper surface of the shell 4. The installation adopts a rivet or screw-free design to prevent accidental extraction of rivets or screws from damaging vehicle tires, and the installation can be completed without using special tools.

[0062] The use method of the pavement marking device provided by the embodiment is as follows:

[0063] In the road section where the pavement marking device is needed, a single device is pre-buried at equal intervals to ensure that the ground elevation after completion is flush with the top surface of the device. After the burial is completed, the roller 1 is rotated by manually or air-pressing the manual poking hole 10, so that the whole row of warning marking filaments 9 is completely stretched out from the warning marking filament exit 12.
