Description

Technical Field

[0001] The present invention relates to the technical field of traffic safety signs, and in particular to an automatic early warning flooded road section warning sign. Background Art

[0002] On highways and mountain roads, which are high-speed roads, waterlogged sections are like hidden traps, posing a threat to vehicles on the road that cannot be ignored. Especially in the rainy season or after sudden heavy rains, the frequency of waterlogged sections increases significantly, posing a great challenge to driving safety.

[0003] The reason why flooded roads are a safety hazard is that they reduce the friction coefficient of the road, which increases the braking distance of vehicles and may even cause serious consequences such as skidding and loss of control. For vehicles traveling at high speeds, this risk is infinitely magnified. Once a vehicle enters a flooded area, the driver often needs to react in a very short time, and the slightest mistake may lead to an accident.

[0004] In order to meet this challenge, traffic management departments have taken a variety of measures to warn of flooded roads. Among them, setting up traffic signs for flooded roads is the most common and effective means. These signs are usually designed with eye-catching colors and patterns to attract the attention of drivers from a distance. At the same time, in order to ensure the stability and durability of the signs, single-column support is often used. This support method is not only simple in structure and easy to install, but also can withstand a certain amount of wind and impact force, ensuring that the signs can still function under severe weather conditions.

[0005] First, due to the static board image, the driver cannot judge whether the road surface is flooded at the time through the information on the traffic board, and the notification effect of the driver is poor; secondly, it is difficult for the driver to understand the state of water accumulation on the road, which can easily lead to misjudgment and make it difficult to effectively improve the safety of driving on flooded roads. Summary of the invention

[0006] According to the technical problem raised above, an automatic early warning waterlogged road section warning sign is provided.

[0007] The technical means adopted by the present invention are as follows:

[0008] An automatic early warning flooded road warning sign comprises a supporting column, a warning sign plate and a buoyancy system, wherein the supporting column is connected to the warning sign plate, the warning sign plate comprises a first plate surface and a second plate surface, the second plate surface is connected to the buoyancy system, in a first state, the second plate surface covers the first plate surface, and in a second state, as the water level rises, the buoyancy system assists the second plate surface to move away from the first plate surface, so that the first plate surface is exposed.

[0009] Furthermore, the warning sign plate is fixedly mounted on the top of the supporting column through multiple groups of plate surface connectors.

[0010] Furthermore, the second board surface is a sign board for slowing down on flooded road surface, and the color of the accumulated water and the road surface on the sign board is black, and the first board surface is a sign board for the accumulated water and the road surface in red.

[0011] Furthermore, the support column and warning sign plate are hollow structures, the support column is provided with a branch pipe for water intake, the buoyancy system includes a float arranged in the branch pipe, a connecting rope, and a rotating shaft, the density of the float is less than that of water and has a preset weight that can overcome the gravity of the second board surface in the first state, a fixing part for fixing the rotating shaft is arranged inside the support column, one end of the connecting rope is connected to the float, and the other end is connected to the second board surface after passing around the rotating shaft.

[0012] Furthermore, the bottom of the supporting column is fixedly installed in the roadside soil foundation, the branch pipe is a right-angle pipe, the water inlet end of which is set downward, and the other end is connected to the bottom of the supporting column, and the number of the rotating shafts is at least three, which are respectively arranged on the vertical section of the branch pipe, the bottom vertical section of the supporting column flush with the vertical section of the branch pipe, and the upper vertical section matching the height of the warning sign plate.

[0013] Furthermore, the first plate surface and the second plate surface are provided with a supporting rotating buckle and a movable connecting buckle, and the first plate surface and the second plate surface are connected by the supporting rotating buckle. The end of the supporting rotating buckle is a circular ring, and the second plate surface is rotatably connected to the circular ring through the movable connecting buckle.

[0014] Furthermore, a column cap is provided at the top end of the supporting column.

[0015] Compared with the prior art, the present invention has the following advantages: Compared with the traditional sign, the structure of the present invention is more novel, the function is no longer single, and the effect is intuitive. Through the change of water level, the float moves up and down, causing the information on the sign board to change with the change of the water accumulation state, providing real-time water accumulation information for the driver, further reminding the driver to pay attention to the water accumulation, slow down and prevent traffic accidents.

In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0033] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0034] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0035] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0036] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0037] like Figures 1 to 12 As shown, an embodiment of the present invention discloses an automatic early warning flooded road section warning sign, including a supporting column 1-1, a warning sign plate and a buoyancy system, wherein the supporting column 1-1 is connected to the warning sign plate, and the warning sign plate includes a first plate surface and a second plate surface, wherein the second plate surface is connected to the buoyancy system, and in a first state, the second plate surface covers the first plate surface, and in a second state, as the water level rises, the buoyancy system assists the second plate surface to move away from the first plate surface, so that the first plate surface is exposed.

[0038] The warning sign plate is fixedly mounted on the top of the supporting column 1-1 through multiple sets of plate surface connectors 1-3.

[0039] The second board surface 2-2 is a sign board for slowing down on flooded roads, and the colors of the water and the road surface on the sign board are black. The first board surface 2-1 is a sign board for the water and the road surface in red.

[0040] The support column 1-1 and the warning sign plate are hollow structures. The support column 1-1 is provided with a branch pipe for water intake, namely a buoyancy column 1-2, and the end of the branch pipe is arranged in a side ditch 4-2 opened in the road 4-1.

[0041] The buoyancy system includes a float 3-1, a connecting rope 3-2 and a rotating shaft 3-3 arranged in the branch pipe. The density of the float 3-1 is less than that of water and has a preset weight that can overcome the gravity of the second board surface in the first state. A fixing part for fixing the rotating shaft is arranged inside the support column. One end of the connecting rope 3-2 is connected to the float 3-1, and the other end is connected to the second board surface after passing around the rotating shaft.

[0042] The bottom of the support column 1-1 is fixedly installed in the roadside foundation 4-3, the branch pipe is a right-angle pipe, the water inlet end of which is set downward, and the other end is connected to the bottom of the support column. The number of the rotating shafts is at least three, which are respectively arranged in the vertical section of the branch pipe, the bottom vertical section of the support column flush with the vertical section of the branch pipe, and the upper vertical section matching the height of the warning sign plate.

[0043] The first plate surface and the second plate surface are provided with a supporting rotating buckle 2-3 and a movable leaf connecting buckle 2-4, and the first plate surface and the second plate surface are connected by the supporting rotating buckle 2-3. The end of the supporting rotating buckle 2-3 is a circular ring, and the second plate surface is rotatably connected to the circular ring through the movable leaf connecting buckle 2-4.

[0044] The top of the support column is provided with a column cap 1-4 to play a protective role.

[0045] When there is no water accumulation, the float 3-1 has a certain deadweight, and the tension of the connecting rope 3-2 can support 2-2 in an upward flipping state. At this time, the sign board surface displays black water accumulation and road surface, which is consistent with conventional information.

[0046] When there is heavy rain or a problem with the drainage system, water 5 accumulates in the ditch and on the road surface. The accumulated water causes the float 3-1 to float up. At this time, the tension of the connecting rope 3-2 is insufficient, causing the second board surface 2-2 to flip downward. At this time, the sign board displays the accumulated water and road surface in red, further reminding the driver to pay attention to the accumulated water and slow down.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
