Description

Technical Field

[0001] The present invention relates to the technical field of highway safety warning, and more particularly to a warning device for highways. Background Art

[0002] Highways, with their unique advantages of being closed, fast, and efficient, have greatly facilitated people's work and life and played an extremely important role in promoting China's economic development. Currently, the mileage of China's highways has ranked second in the world and is increasing at a rate of more than 10% per year. At the same time, with the increase in highway traffic volume, highway traffic accidents occur frequently. Especially the occurrence of secondary accidents on highways often results in multiple vehicle rear-end collisions, heavy casualties, huge economic losses, and bad social impacts. If timely warnings can be given after traffic accidents occur on highways, especially in accident-prone areas, it is expected to avoid the occurrence of secondary accidents and protect the safety of the lives and property of drivers and passengers. A secondary traffic accident refers to a subsequent accident caused by the negligence of the parties or rescue personnel, such as failure to give timely warnings, improper warning measures, or unsatisfactory warning effects, on the basis of an original traffic accident. Secondary traffic accidents are a common phenomenon in current highway traffic accidents in China and are also typical forms of serious traffic accidents such as group deaths, injuries, and vehicle damage. Compared with the first accident, secondary traffic accidents often cause greater harm, more serious personal and property losses, and greatly increase the difficulty of further rescue work. Therefore, secondary traffic accidents are accidents that need to be strongly prevented. In addition, in recent years, the accident rate on highways caused by adverse weather conditions has also been increasing year by year. Mainly after vehicles enter the highway, when encountering sudden adverse weather, due to low atmospheric visibility, drivers are not easily able to detect the vehicles in front. In emergency situations, it is easy to make operation mistakes. If the vehicle speed is relatively fast and it is not possible to brake in time, it is extremely likely to cause traffic accidents such as following collisions. Therefore, when traffic accidents occur on highways or adverse weather is encountered, if timely warnings and guidance can be given to passing vehicles, it will have important practical significance for improving the traffic safety level of China's highways, meeting the growing transportation requirements, and ensuring the safety of people's lives and property. Most of the existing warning devices on highways are warning lights, which cannot play a real interception role. Summary of the Invention

When the drive motor is started, it drives the limit baffle at the starting end to rotate on the bottom plate, and further drives other limit baffles to follow and unfold or fold on the bottom plate through the meshing action. Reflective plates are provided on the limit baffles. When the plurality of limit baffles are in the unfolded state, a wall with a reflective function is formed.

The gear A is meshed with the gear B of the limit baffle at the starting end, so that when the drive motor is started, the movement of the limit baffle at the starting end is driven through the meshing action.

[0010] Furthermore, a first support rod is provided between the gear A and the gear B. Both ends of the first support rod are rotatably connected to the axles of the gear A and the gear B respectively; the meshed gears B and C are connected by a second support rod provided therebetween.

[0024] Continue to refer to Figure 1-2 as shown, side support columns 5 are fixedly connected to both sides of each limit baffle 4, and the side support column 5 of the limit baffle 4 at the starting end is meshed and connected to the driving motor of the side support member. The side support member includes a side baffle 2 and a side support cylinder 3. The side baffle 2 is provided at the end side of the bottom plate 1, and the side support cylinder 3 is connected to a position of the side baffle 2 close to the center of the bottom plate 1. The driving motor is provided inside the side support cylinder 3. The output shaft of the driving motor is connected to the gear A through the top of the side support cylinder 3. In this embodiment, the output shaft of the driving motor is connected to the gear A through a provided bearing.

[0025] Refer to Figure 1-2As shown, the multiple limit baffles 4 are meshed and connected by corresponding gears arranged therebetween. A gear A (6) corresponding to the output shaft of the driving motor is provided on the side support cylinder 3 of the side support member. Gears B (7) and C (8) are respectively provided at both ends of the limit baffle 4. The gears B (7) and C (8) at the corresponding ends between adjacent limit baffles 4 are meshed, so as to drive the meshed connection of the corresponding limit baffles 4. The gear A (6) is meshed with the gear B (7) of the limit baffle 4 at the starting end, so that when the driving motor is started, the movement of the limit baffle (4) at the starting end is driven through the meshing effect. A first support rod 9 is provided between the gear A (6) and the gear B (7). Both ends of the first support rod 9 are rotatably connected to the axles of the gear A (6) and the gear B (7); the meshed gears B (7) and C (8) are connected by a second support rod (10) provided therebetween. Both ends of the second support rod (10) are rotatably connected to the axles of the gear B (7) and the gear C (8); two third support rods 11 and a fourth support rod 12 are provided between the gears B (7) and C (8) respectively provided on each limit baffle 4. Both ends of the fourth support rod 12 are hinged to the second ends of the two third support rods 10.

When the driving motor is started, the unfolding or folding of each limit baffle 4 is driven through the meshing effect of each gear and the supporting connection effect of each support rod, so that the unfolding and folding of the entire device are very conveniently realized, and the use is convenient.

[0026] In this embodiment, reflective plates are provided on both sides of the limit baffle 4.

[0027] In this embodiment, reflective plates identical to those on the limit baffle 4 are provided on both sides of the side support member. In this embodiment, the reflective plates are provided on both sides of the side baffle 2.

[0028] In this embodiment, with reference to Figure 1-2 As shown, the limit baffle 4 located at the end position is not provided with the gear C, nor the third support rod 11 and the fourth support rod 12.

[0029] In this embodiment, the size of the fourth support rod 12 matches the width of the limit baffle 4.

[0030] A method for using a warning device for highways disclosed in an embodiment of the present invention is as follows: During the use of the device, after starting the drive motor, the control gear A (6) rotates, and the gear B (7) of the starting limit baffle 4 that meshes therewith rotates, causing the starting limit baffle 4 to unfold or close. The linked support rod four 12 and support rod three 11 cause the gear C (8) of the starting limit baffle 4 that meshes with each other and the gear B (7) of the adjacent limit baffle 4 to rotate, thereby controlling the unfolding or closing of the adjacent limit baffle 4. And so on, causing all the limit baffles 4 to unfold or close. This enables multiple limit baffles 4 to form a limit retaining wall to intercept vehicles or close the highway. Reflective plates are installed on the limit baffles 4, which can strongly remind the vehicle owners that the front is a dangerous section; the device has a firm structure, a high degree of automation, and is convenient to use.

[0031] In summary, a warning device for highways provided by an embodiment of the present invention has the following beneficial technical effects: By providing multiple limit baffles and cooperating with the reflective plates provided thereon, the present invention can strongly warn passing vehicles that the corresponding section is a dangerous section, has a longer warning distance, and has a better warning effect; the device has a firm structure, a high degree of automation, and is convenient to use.
