Technical Field

[0001] The present invention relates to the technical field of road equipment, and in particular to a road indicating device used for sponge city construction. Background Art

[0002] The information disclosed in the background technology section of the present invention is only intended to deepen the understanding of the general background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

[0003] Sponge city is a new generation of urban stormwater management concept. It means that the city can adapt to environmental changes and deal with natural disasters caused by rainwater like a sponge, and has good elasticity. It can also be called a "water-elastic city". In the process of sponge city construction, there are strict control requirements for the planning and construction of municipal roads. Among them, road sign devices, as a guarantee facility to maintain the stable operation of the traffic system, play an important role in the process of sponge city construction. How to ensure that the road sign devices can continue to and stably play the role of road signs when natural disasters such as rain occur, and guide vehicles to drive safely and orderly, is particularly important.

[0004] Existing road sign devices lack effective protection measures. Road sign devices installed on the roadside are easily hit by flying stones rolled up by passing vehicles, causing damage to the indicator lights and loss of indication function. In addition, road sign devices are exposed to the outdoor environment for a long time, and the surface of the indicator lights is easily contaminated by impurities such as dust and dirt, affecting the normal indication effect. Especially in rainy weather, road sign devices are prone to water ingress, resulting in functional abnormalities. They cannot meet the needs of ensuring the stable operation of the transportation system when natural disasters such as rain occur, and are not in line with the purpose of sponge city construction. Summary of the invention

[0005] Based on this, it is necessary to provide a road sign device for sponge city construction to address the problems of lamps being easily damaged and polluted in current road sign devices, which affect their normal effects.

[0009] Preferably, a supporting spring sheet is provided on the indicating side of the indicator light corresponding to the protective cover to provide a certain elastic supporting force to the windward surface of the protective cover.

[0010] Preferably, the protection assembly further comprises a brush roller for cleaning the protection cover, wherein the brush roller is rotatably connected to the upper protection cover and the lower protection cover, and is rollingly connected to the protection cover.

[0011] Preferably, the center of the brush roller is fixedly connected to a brush roller shaft, the center of the rotating roller is fixedly connected to a rotating roller shaft, and the brush roller shaft is transmission-connected to the rotating roller shaft.

[0012] Preferably, the brush roller shaft is connected to the rotating roller shaft through gear meshing transmission.

[0013] Preferably, the brush roller shaft and the rotating roller shaft are connected via a belt drive so that the two rotate in the same direction.

[0014] Preferably, a dust discharge port is provided on the lower protective cover corresponding to the brush roller, and a dust collecting cover for suppressing dust diffusion is provided on the periphery of the brush roller.

[0015] Preferably, the protective component also includes a ventilation structure for ventilation and heat dissipation of the indicator light, the ventilation structure includes an air inlet hole opened on the lower protective cover on the indication side of the indicator light, and an exhaust hole arranged on the opposite side, the indicator light is provided with a through heat dissipation hole, and the air inlet hole and the through heat dissipation hole are both provided with a one-way valve, so that the air inlet hole can only take in air from the outside to the inside, and the through heat dissipation hole can only ventilate from the air inlet hole to the exhaust hole. The upper and lower end surfaces of the protective cover are fixedly connected with flexible sealing rings, so that the protective cover is slidably sealed with the upper protective cover and the lower protective cover through the flexible sealing ring, and the indicator light is provided with a sealing strip that is slidably connected to the rotating roller, so that a number of relatively closed chamber structures are formed between the indicator light and the protective cover.

[0016] Preferably, a drainage hole is provided on the lower protective cover, and a solar panel is arranged on the side of the indicator light.

[0017] The beneficial effects of the present invention are:

[0018] The present invention effectively prevents the interference of flying stones, rain, dust, etc. on the normal operation of the indicator light by setting a closed protective component on the outside of the indicator light, and provides a strong guarantee for the stable operation of the road traffic system. In the present invention, the protective cover is a cylindrical structure made of a transparent sheet material, and is connected between the upper protective cover and the lower protective cover by a rotating roller.

When the protective cover is impacted by the airflow, its windward surface will be concave inward. At this time, the windward surface of the protective cover will generate a pulling force on the protective cover in other areas. Under the restriction of the one-way rotating roller of the rotating roller, the pulling force will eventually act on the tensioning mechanism, pulling the tensioning roller to overcome the spring elastic force and move inward; when the airflow impact ends, the spring will push the tensioning roller to reset. In this process, under the restriction of the one-way rotation of the rotating roller, the reset of the tensioning roller will drive the protective cover to move in one direction, realizing the automatic one-way cycle replacement of the protective cover.

[0020] The brush roller is set to roll and clean the dust and impurities attached to the surface of the protective cover when the protective cover is replaced, so as to achieve the purpose of automatically cleaning the protective cover. The setting of the ventilation structure reasonably utilizes the impact of airflow, ensures good heat dissipation of the indicator light, and ensures the working stability and service life of the indicator light. The road indication device provided by the present invention can meet the guarantee demand for stable operation of the traffic system when natural disasters such as rain occur, and is more in line with the planning and construction purpose of municipal roads in sponge cities.

[0034] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0035] like Figure 1-9 As shown, a road indication device for sponge city construction includes a mounting base 100, on which an indicator light 200 for road indication is arranged, and a protective assembly 300 for protecting the indicator light 200 is arranged corresponding to the indicator light 200, and the protective assembly 300 includes a protective cover 310 arranged to surround the indicator light 200, and the protective cover 310 is a cylindrical structure made of a transparent sheet material, and the upper end and the lower end of the protective cover 310 are respectively connected to an upper protective cover 320 and a lower protective cover 330, and together form a closed shell structure that can accommodate the indicator light 200. The closed structure of the protective assembly 300 can effectively resist the interference of flying stones, rain, dust, etc. on the normal operation of the indicator light 200, and provide a strong guarantee for the stable operation of the road traffic system.

[0036] As a preferred embodiment, the protective cover 310 is circumferentially slidably connected to the upper protective cover 320 and the lower protective cover 330, so that the protective cover 310 can be transposed to the position of the indicator light 200 in different directions. Specifically, a plurality of rotating rollers 340 are arranged between the upper protective cover 320 and the lower protective cover 330, and the protective cover 310 is sleeved on a bracket formed by the plurality of rotating rollers 340 and is rollingly connected with the rotating rollers 340. When the road indication device is installed, the indicating side 250 (i.e., the luminous side) of the indicator light 200 will face the direction of the oncoming vehicle on the road. When the protective cover 310 on the indicating side 250 of the indicator light 200 is accidentally damaged or contaminated, the protective cover 310 can be pushed to move around the bracket formed by the rotating rollers 340, so that the damaged or contaminated area is moved away from the indicating side 250 of the indicator light 200, and the intact protective cover 310 area is transposed to the indicating side 250 of the indicator light 200 to maintain a good indication effect.

[0037] When a vehicle passes by the indicating device, the protective cover 310 will be subjected to a certain amount of airflow impact, among which the area of ​​the protective cover 310 facing the direction of the oncoming vehicle will be most significantly impacted. This embodiment will make full use of the impact force of the airflow and convert it into power for the protective cover 310 to automatically move and change position. Specifically, a tensioning mechanism 360 is provided between the upper protective cover 320 and the lower protective cover 330 corresponding to the protective cover 310. The tensioning mechanism 360 includes a tensioning roller 361 that is rotatably connected to the upper protective cover 320 and the lower protective cover 330. The rotating shaft of the tensioning roller 361 is elastically connected to the upper protective cover 320 and the lower protective cover 330 through a spring 362. The protective cover 310 is sleeved on a bracket formed by the rotating roller 340 and the tensioning roller 361, and is rollingly connected to the tensioning roller 361. In this embodiment, the rotating roller 340 is a one-way roller, that is, the rotating roller 340 can only rotate in one direction. Under the restriction of the one-way roller, the protective cover 310 can only move in the direction of the fixed side. As Figure 6 As shown, when the protective cover 310 is impacted by the airflow, its windward surface 312 will be concave inward. At this time, the windward surface 312 of the protective cover 310 will generate a pulling force on the protective cover 310 in other areas. Due to the limiting effect of the unidirectional rotation of the rotating roller 340, the pulling force will eventually act on the tensioning mechanism 360, pulling the tensioning roller 361 to overcome the elastic force of the spring 362 and move inward. When the airflow impact ends, the spring 362 will push the tensioning roller 361 to reset. In this process, due to the limiting effect of the unidirectional rotation of the rotating roller 340, the reset of the tensioning roller 361 will drive the protective cover 310 to move in one direction, thereby realizing the automatic unidirectional cycle replacement of the protective cover 310.

[0038] In a further embodiment, Figure 2 , 5 As shown in Figures 6, the indicating side 250 of the indicator light 200 is provided with a supporting spring piece 210 corresponding to the protective cover 310 to provide a certain elastic supporting force to the windward surface 312 of the protective cover 310, so as to facilitate the protective cover 310 to quickly recover after the airflow impact ends and maintain the flatness of the windward surface 312 of the protective cover 310 to ensure the indicating effect; at the same time, the destructive effect of the large airflow impact on the protective cover 310 is weakened, thereby extending the service life of the protective cover 310.

[0039] Furthermore, the protection assembly 300 further includes a brush roller 370 for cleaning the protection cover 310. The brush roller 370 is rotatably connected to the upper protection cover 320 and the lower protection cover 330, and is rollingly connected to the protection cover 310. When the protection cover 310 is replaced, the brush roller 370 will roll and clean the dust and impurities attached to the surface of the protection cover 310, thereby achieving the purpose of automatically cleaning the protection cover 310.

[0040] Preferably, if Fig. 9As shown, the center of the brush roller 370 is fixedly connected to the brush roller shaft 371, the center of the rotating roller 340 is fixedly connected to the rotating roller shaft 341, and the brush roller shaft 371 is transmission-connected to the rotating roller shaft 341. The rotation of the rotating roller 340 drives the brush roller 370 to rotate, thereby completing the action of the brush roller 370 rolling to clean the protective cover 310.

[0041] Preferably, the brush roller 371 can also be connected to the rotating roller 341 through gear meshing transmission to achieve opposite rotation of the two. During the movement of the protective cover 310, the rotating roller 341 will drive the brush roller 371 to rotate synchronously, thereby completing the cleaning process of the protective cover 310.

[0042] Preferably, the brush roller 371 can also be connected to the rotating roller 341 through the belt 350 to achieve synchronous rotation of the two. In this embodiment, the rotation direction of the brush roller 370 is opposite to the moving direction of the protective cover 310, which improves the brush roller 371's ability to clean the surface of the protective cover 310.

[0043] Furthermore, the lower protective cover 330 is provided with an ash discharge port 372 corresponding to the brush roller 370, and the ash and other impurities swept by the brush roller 370 are discharged through the ash discharge port 372. A dust collecting cover 373 for suppressing dust diffusion is arranged on the periphery of the brush roller 370, and the ash discharge port 372 is provided at the lower end of the dust collecting cover 373 to facilitate the centralized discharge of dust and impurities, effectively avoiding secondary contamination of the protective cover 310 and improving the cleaning effect.

[0044] The protection component 300 also includes a ventilation structure for ventilation and heat dissipation of the indicator light 200. The ventilation structure includes an air inlet 381 provided on the lower protective cover 330 on the indicating side 250 of the indicator light 200, and an exhaust hole 382 provided on the opposite side. The indicator light 200 is provided with a through heat dissipation hole 230. Both the air inlet 381 and the through heat dissipation hole 230 are provided with a one-way valve 384, so that the air inlet 381 can only take in air from the outside to the inside, and the through heat dissipation hole 230 can only ventilate from the air inlet 381 to the exhaust hole 382. Figure 4 , 7 As shown, in this embodiment, the upper and lower end surfaces of the protective cover 310 are fixedly connected with flexible sealing rings 311, and the protective cover 310 is slidably sealed with the upper protective cover 320 and the lower protective cover 330 through the flexible sealing rings 311. The provision of the flexible sealing rings 311 improves the sealing performance between the protective cover 310 and the upper protective cover 320 and the lower protective cover 330, and can still maintain a good seal when the windward surface 312 of the protective cover 310 is impacted by the airflow and is concave. The indicator light 200 is provided with a sealing strip 220 that is slidably connected to the rotating roller 340, so that a number of relatively closed chamber structures 385 are formed between the indicator light 200 and the protective cover 310.

[0045] When in use, when the windward surface 312 of the protective cover 310 is impacted by the airflow and is concave inward, the chamber structure 385 between the windward surface 312 of the protective cover 310 and the indicator light 200 will be compressed, so that the cold air in the chamber enters the interior of the indicator light 200 through the heat dissipation holes for heat exchange, and the hot air after heat exchange is finally discharged through the exhaust hole 382, ​​completing a ventilation of the indicator light 200; when the airflow impact ends, the windward surface 312 of the protective cover 310 will quickly restore to flatness under the action of the tensioning mechanism 360 and the supporting spring sheet, and the chamber structure 385 between the protective cover 310 and the indicator light 200 will also be restored and generate a certain negative pressure in the chamber, and fresh cold air will be sucked into the chamber through the air inlet 381. In this process, the supporting spring sheet 210 can play a driving force to support the rapid recovery of the protective cover 310, and assist the chamber structure 385 to replenish fresh air in time. This embodiment ensures good heat dissipation of the indicator light 200 and extends the service life of the indicator light 200.

[0046] The lower protective cover 330 is provided with a drainage hole 331 to facilitate the timely discharge of rainwater. A solar panel 240 is provided on the side of the indicator light 200 to collect sunlight and store it as the electrical energy required by the indicator light 200, thereby achieving the purpose of environmental protection and energy saving.

[0047] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
