Description

Technical Field

[0001] The utility model relates to the technical field of traffic management, in particular to a bidirectional warning device with an adjustable display surface for an intersection without traffic signal lights. Background Art

[0002] Bad weather and environment at night, rain, snow, fog, haze or thick smoke, or accidents or abnormal conditions on the road will bring major safety hazards to vehicles, drivers and passengers in the car, and pedestrians on the road. Especially at intersections without traffic lights, if there is no road warning information display device that broadcasts traffic conditions in time, the possibility and danger of traffic accidents will increase.

[0003] At present, at national and provincial trunk roads without traffic lights and T-shaped or cross-shaped intersections, two-way warning devices are usually installed to broadcast dynamic traffic warning information to drivers, passengers and pedestrians. The angle of the intersecting roads at the above-mentioned intersections is generally within the range of 90±15°. However, the two display surfaces of the existing two-way warning devices facing the main road and the branch road are uniformly designed to be 90°. When the angle deviation of the intersecting roads is large, the vehicle driving direction is not perpendicular to the warning display surface, that is, the warning display surface cannot face the direction of the oncoming vehicle on the branch road, which greatly reduces the visual recognition effect of the warning information.

[0004] Therefore, there is an urgent need for a new bidirectional warning device with an adjustable display surface for intersections without traffic lights to solve the above problems. Utility Model Content

[0051] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0052] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0053] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0054] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; "connection" can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] See also Figures 1 to 7 The utility model provides a bidirectional warning device with adjustable display surface for intersections without traffic lights, which specifically includes a square column 3 and a first warning information display screen 4 and a second warning information display screen 5 arranged on the square column 3. The square column 3 is an internal hollow structure, which is used to be installed on the road side of the intersection of the main road 1 and the branch road 2, and can be preferably installed on the right side of the direction where the branch road 2 merges into the main road 1 (see Figure 1 , Figure 3and Figure 6 The first warning information display screen 4 is arranged on the first side surface 310 of the square column 3, and is used to display dynamic warning information to the main road 1, so that the display surface of the first warning information display screen 4 faces the direction of the oncoming vehicle of the main road 1, ensuring that when the vehicle is traveling on the main road 1 with a large traffic flow, the driver can obtain the road condition information ahead in time, so as to plan the route in advance, thereby reducing the possibility and danger of traffic accidents.

[0056] The second warning information display screen 5 is hinged on the second side surface 320 of the square column 3 adjacent to the first side surface 310, and its hinge axis extends vertically and is used to display dynamic warning information to the branch road 2. The second warning information display screen 5 can be opened inward or outward based on the second side surface 320 of the square column 3, so that the second warning information display screen 5 faces the direction of the vehicle on the branch road 2. When the branch road 2 is perpendicular or not perpendicular to the main road 1, the on-site debugging personnel can adjust the direction of the second warning information display screen 5 according to the direction of the branch road 2 to ensure that the display surface of the second warning information display screen 5 always faces the direction of the vehicle on the branch road 2. For example, see Figure 1 and Figure 2 , when the main road 1 and the branch road 2 intersect vertically, the second warning information display screen 5 remains in a state of closing the second side surface 320; see Figure 3 and Figure 4 When the main road 1 and the branch road 2 intersect at an acute angle, the second warning information display screen 5 opens outwards and maintains a certain angle with the second side surface 320; see Figure 6 and Figure 7 When the main road 1 and the branch road 2 intersect at an obtuse angle, the second warning information display screen 5 opens inwards and maintains a certain angle with the second side surface 320. Even when the angle deviation of the intersecting roads is large, the driving direction of the vehicle on the branch road 2 and the display surface of the second warning information display screen 5 can still remain substantially perpendicular (that is, the second warning information display screen 5 always faces the direction of the vehicle on the branch road 2), thereby greatly improving the visual recognition effect of the warning information, so as to ensure that the driver on the branch road 2 can also obtain the road condition information ahead in time, so as to plan the route in advance.

[0057] Specifically, when debugging, the on-site debugging personnel will first make the first warning information display screen 4 perpendicular to the extension direction of the main road 1 (i.e., the direction of vehicle travel), and then make the second warning information display screen 5 perpendicular to the extension direction of the branch road 2 (i.e., the direction of vehicle travel). In a preferred embodiment, the angle between the second side surface 320 of the square column 3 and the second warning information display screen 5 is β, where -15°≤β≤15°, so that the second warning information display screen 5 is adjustable within the range of ±15°, so as to be applicable to various T-type or cross-type level crossings within the range and optimize the viewing angle.

[0058] In addition, considering the situation where the angle of the intersecting roads is outside the range of 90°±15°, in another optional embodiment, the first warning information display screen 4 is hinged to the first side surface 310 of the square column 3 based on the vertical hinge axis, and the first warning information display screen 4 can be opened inward or outward based on the first side surface 310 of the square column 3, so that the first warning information display screen 4 faces the direction of the oncoming vehicle of the main road 1. Since the first warning information display screen 4 and the second warning information display screen 5 are both set to an articulated installation mode, they can adapt to different road conditions, thereby expanding the scope of application of the device. Among them, when the first warning information display screen 4 and the second warning information display screen 5 are both installed in an articulated manner, the specific structures of the two are similar. The specific structure will be described below using the second warning information display screen 5 as an example.

[0059] In order to facilitate disassembly and assembly, improve the overall strength of the display and extend its service life, see Figures 7 to 10 The second warning information display screen 5 is wrapped with a square door frame 51, which has a first side column and a second side column opposite to each other and an upper beam and a lower beam opposite to each other. The first side column of the square door frame 51 is hinged in the door opening 321 on the second side surface 320 of the square column 3. The square door frame 51 can protect the second warning information display screen 5. In addition, the top surface of the upper beam of the square door frame 51 can also be formed with angle scale lines (see Fig.18 ), that is, an angle scale is coded on the top surface of the square door frame 51 so that on-site commissioning personnel can adjust the angle according to actual needs.

[0060] Specifically, Figures 11 to 13 As shown, the top and bottom surfaces of the first side column of the square door frame 51 are respectively fixedly mounted with a rotating shaft 531, the rotating shaft 531 is connected to the square door frame 51 as a whole, a bearing seat mounting plate 532 is mounted at a position corresponding to the rotating shaft 531 on the door opening 321, a bearing seat 533 is mounted on the bearing seat mounting plate 532 by a plurality of fixing screws 534, and the rotating shaft 531 can be rotatably mounted in the bearing seat 533, wherein the bearing seat 533 can be an outer spherical bearing seat. The second warning information display screen 5 can be hingedly mounted by the bearing mounting mechanism symmetrically arranged at the upper and lower ends of the first side column of the square door frame 51.

[0061] See also Figure 8 , a limiting mechanism 52 is also provided on the square column 3, and the limiting mechanism 52 connects the second side column of the square door frame 51 and the door opening 321 or connects the position near the second side column on the upper beam / lower beam of the square door frame 51 and the door opening 321, so that the second warning information display screen 5 can always be kept within the preset angle during operation. In a preferred embodiment, as Figures 8 to 10 and Figure 15 to Figure 16As shown, the limiting mechanism 52 includes a mounting plate 521 disposed in the square column 3 and close to the door opening 321, a mounting bolt 522 disposed on the mounting plate 521, and a limiting piece 523 whose first end is rotatably mounted on the mounting bolt 522, and a waist-shaped hole is provided at the second end of the limiting piece 523. Correspondingly, a limiting nail 524 is provided on the square door frame 51, and the waist-shaped hole can be sleeved on the limiting nail 524.

[0062] See also Figures 8 to 10 When the second warning information display screen 5 is kept in a closed state, the limiting pieces 523 are all located on the upper beam of the square door frame 51, and the limiting nails 524 are located in the middle of the waist-shaped hole; see Figure 4 When the second warning information display screen 5 is opened outward and maintains a certain angle with the second side surface 320, the limiting piece 523 extends outward, and the limiting nail 524 is located at the far end of the waist-shaped hole to limit the maximum angle of the second warning information display screen 5 to open outward; see Figure 15 to Figure 16 , the second warning information display screen 5 opens inwards and maintains a certain angle with the second side surface 320, the limiting piece 523 extends inwards, and the limiting nail 524 is also located at the far end of the waist-shaped hole to limit the maximum angle of the second warning information display screen 5 to open inwards. When the on-site debugging personnel are debugging, after adjusting the angle of the second warning information display screen 5, the limiting nail 524 is tightened on the square door frame 51, so as to lock the limiting piece 523 between the limiting nail 524 and the square door frame 51 to prevent the second warning information display screen 5 from swinging during operation. The above embodiment limits the swing angle of the second warning information display screen 5 by the limiting piece 523, and can limit the swing angle within the range of ±15° according to the road angle range.

[0063] Considering that the display surface adjustable bidirectional warning device used outdoors needs to cope with rainy and snowy weather, in a preferred embodiment, see Fig.14 The upper beam, the lower beam and the second side column of the square door frame 51 are all provided with an accordion-type sealing cover 54, and the side of the accordion-type sealing cover 54 away from the square door frame 51 can be installed on the door opening 321 to prevent rainwater from entering the square door frame 51 from the door opening 321. Since the accordion-type sealing cover 54 can be made of rubber and can be folded or stretched along the fold, it can be flexibly installed in accordance with different opening angles of the second warning information display screen 5.

[0064] Further, in a preferred embodiment, Figure 2 As shown, the upper parts of the first side 310 and the second side 320 of the square column 3 are respectively provided with standard indicator lights 6 to meet various traffic management requirements. Fig.17 As shown, a maintenance door 7 is hingedly provided on the third side surface 330 of the square column 3 opposite to the second side surface 320 to facilitate maintenance of the bidirectional warning device with adjustable display surface.

[0065] It should be understood that the above description of the specific embodiments of the utility model is only for illustrating the technical route and features of the utility model, and its purpose is to enable those skilled in the art to understand the content of the utility model and implement it accordingly, but the utility model is not limited to the above specific implementation methods. All changes or modifications made within the scope of the claims of the utility model should be included in the protection scope of the utility model.
