Meanwhile, the prompt board assembly 2 further comprises a rotary support 23; the rotary support 23 is arranged at the position where the prompt board body 21 is connected with the support column assembly 1, and is used to support and limit the prompt board body 21. The road sign device further comprises an alarm 5; the alarm 5 is arranged on the prompt board body 21. In this embodiment, the prompt board body 21 is an indicator or an indicator body arranged on the road; the rotating module 22 comprises a rotating motor and a worm gear reducer assembly 221, a driving wheel 222 and a driven wheel 223; the driving wheel 222 is fixedly arranged at the output end of the rotating motor and the worm gear reducer assembly 221; the driven wheel 223 is sleeved on the prompt board body 21 and is engaged with the driving wheel 222; the rotating motor and the worm gear reducer assembly 221 are used as the driving assembly, which can not only drive the prompt board body 21 to rotate, but also control the rotation speed of the prompt board body 21; and in other embodiments, other assemblies capable of realizing rotation driving can be used instead of the rotating motor and the worm gear reducer assembly 221 in this embodiment. In this embodiment, the support column assembly 1 only comprises a support rod, and the prompt board assembly 2 is arranged at the upper end of the support rod, so that the height of the prompt board assembly 2 is not adjustable; and in other embodiments, the support column assembly 1 can be composed of multiple sections of support rods which are liftable, so that the height of the prompt board assembly 2 arranged at the upper end of the support column assembly 1 is adjustable; or the prompt board assembly 2 is driven to move up and down along the support column assembly 1 by a motor, a pulley set or the like.

[0031] In addition, the road sign device further comprises a follow-up support assembly 3; the follow-up support assembly 3 is arranged below the sign assembly 2, and one end of the follow-up support assembly 3 is inserted into the support column assembly 1, and the other end is fixedly connected with the sign body 21; the follow-up support assembly 3 rotates with the sign body 21 and supports the sign body 21, so as to prevent the sign body 21 from tilting downward under the action of its own gravity when the sign body 21 is in working state for a long time. As shown in Figure 3 the follow-up support assembly 3 comprises a follow-up support plate 31, a follow-up support wheel 32 and a follow-up support rail 33; the follow-up support rail 33 is sleeved on the support column assembly 1; one end of the follow-up support plate 31 is fixedly connected with the sign body 21, and the other end is connected with the follow-up support wheel 32; the follow-up support wheel 32 is embedded into the follow-up support rail 33 and moves along the follow-up support rail 33 with the rotation of the sign body 21.

[0032] Embodiment two

[0033] When the one-way road is wide, such as one-way three-lane, four-lane, five-lane, etc., in order to ensure that the oncoming vehicles of each lane can clearly see the prompt content on the prompt plate body 21, the prompt plate body 21 needs to have a relatively long length; however, the longer the length of the prompt plate body 21, the greater its own weight; in the process of rotation, the prompt plate body 21 will appear unstable phenomena such as shaking, swinging, etc.; and in the working state, due to the influence of its own weight, the end of the prompt plate body 21 away from the support column assembly 1 is prone to sinking, falling, which is very dangerous and will also cause great safety hazards; and it is also not conducive to the prompt plate body 21 being in a working state for a long time. Therefore, the difference between the present embodiment and the first embodiment is that the road sign device provided in the present embodiment simultaneously includes two support column assemblies 1 and two locking devices 4; the two support column assemblies 1 are both transversely provided with a prompt plate assembly 2. Among them, the two support column assemblies 1 are symmetrically arranged on both sides of the one-way wide road, and the two locking devices 4 are also arranged on both sides of the one-way wide road and are arranged in a spaced manner with the support column assembly 1 arranged on the same side of the road. When the road sign device is in a non-working state, i.e. in situ, the prompt plate body 21 at the upper end of the two support column assemblies 1, away from the support column assembly 1, is locked on the locking column 41 respectively; as shown in Figure 4 , when the road sign device needs to work, the prompt plate body 21 at the upper end of the two support column assemblies 1 rotates to the working position above the road in the opposite direction.

[0034] In addition, in the present embodiment, the support column assembly 1 includes a main column 11, a lifting module 13, and a lifting column 12; wherein one end of the lifting column 12 is inserted into the main column 11, and the other end is connected with the prompt plate assembly 2; the output end of the lifting module 13 is connected with the lifting column 12, for driving the lifting column 12 to move up and down, thereby adjusting the height of the prompt plate body 21; when encountering strong winds, typhoons and other bad weather, the position of the prompt plate body 21 can be adjusted to a non-working state, and the prompt plate body 21 in the non-working state is lowered to the lowest position, which helps to reduce the damage of bad weather to the road sign device. In the present embodiment, the lifting module 13 is a combination of a hydraulic push rod and a motor arranged in the main column 11; while in other embodiments, the lifting module 13 can also be other modules that can drive the lifting column 12, such as air cylinders, electric cylinders, motor and gear rack assemblies, etc.

[0035] Embodiment three

[0036] In the case of one-way road with one lane or two lanes, the length of the sign body 21 can be set slightly larger than the width of the road to ensure that the vehicles in each lane can clearly see the prompt content on the sign body 21. Meanwhile, to avoid the phenomenon of falling of the end of the sign body 21 away from the support column assembly 1 under the influence of its own weight in the working state, a locking device 4 can also be arranged at the position symmetrical to the support column assembly 1 on the other side of the road. Therefore, the difference between the present embodiment and the second embodiment is that the road sign device comprises one support column assembly 1 and two locking devices 4. The support column assembly 1 is arranged on one side of the one-way road, one of the locking devices 4 is arranged at the position symmetrical to the support column assembly 1 on the other side of the road, and the other locking device 4 is arranged on the same side of the road together with the support column assembly 1. As shown in Figure 5 , when the road sign device is in the non-working state, the sign body 21 is lowered to the lowest position, and the end of the sign body 21 away from the support column assembly 1 is locked on the locking device 4 arranged on the same side of the road together with the support column assembly 1 by the lifting pin 42. As shown in Figure 6 , when the road sign device needs to be in the working state, the lifting pin 42 will move downward to release the locking of the sign body 21. Then the lifting column 12 is driven to move upward by the lifting module 13, and the lifting column 12 and the sign body 21 are raised to the appropriate position. After that, under the drive of the rotating module 22, the sign body 21 rotates to the working position above the road with the axis of the support column assembly 1 as the rotating shaft, and the end of the sign body 21 away from the support column assembly 1 contacts the locking device 4 arranged on the other side of the road, which is locked by the lifting pin 42 on the locking device 4.
