When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] When investigating a traffic accident, it is necessary to place early warning equipment behind the accident to remind the vehicles behind that a traffic accident is being handled ahead. The current protective early warning for traffic accident investigation is mainly in the form of cones and isolation belts. Both of the above methods have a major flaw, which is mainly reflected in the small overall structure. Especially on highways at night, vehicles travel faster and the reflective strips can only be seen clearly when the vehicle drives near the cone. Therefore, it is very easy for the driver to hit the cone if he does not react in time or slam the steering wheel to cause a rollover.

[0043] In view of this, the present invention provides a road warning device. Figures 1 to 6 This is an embodiment of the road warning device provided by the present invention.

[0044] Please refer to Figures 1 to 3The road warning device 100 includes a base 1, a lifting mechanism 2, a support assembly and a warning wall assembly 4, wherein the base 1 can move in a horizontal plane, the lifting mechanism 2 includes a top plate 21 that can be movably mounted to the base 1 in an up-and-down direction, the support assembly includes at least one shaft rod 3a that can be rotatably mounted to the top plate 21 along an axial direction extending in a horizontal direction, the shaft rod 3a includes a hanging portion that protrudes laterally from the top plate 21 and is arranged on the top plate 21, the warning wall assembly 4 includes a plurality of connecting wires 41, the upper ends of the plurality of connecting wires 41 are all fixed to the hanging portion, the lower ends of the plurality of connecting wires 41 are all connected to magnets 42, the magnetism of each adjacent two magnets 42 is opposite, the plurality of connecting wires 41 can be rolled up or unfolded when the shaft rod 3a rotates, and the plurality of connecting wires 41 together constitute a warning wall surface, which is used to apply warning slogans.

[0045] In the technical solution of the present invention, rotating the shaft 3a can drive the multiple connecting lines 41 to be rolled up or unfolded, so as to be stored and used for road warning. The multiple magnets 42 attract and cooperate with each other so that the multiple connecting lines 41 together form a relatively stable warning wall, maintain the stability of the bottom, and prevent the connecting lines 41 from being scattered due to being blown in windy weather. The warning wall is used to apply warning slogans, and the position of the warning wall can be adjusted by adjusting the height of the top plate 21 in the up and down directions. The area of ​​the warning wall can be increased by raising the top plate 21 and increasing the size of the hanging part, and a multi-lane curtain wall warning can be realized, thereby ensuring the visible area for vehicles coming from behind, and warning vehicles farther away. At the same time, the base 1 can be moved to realize the overall movement of the equipment, which is flexible and convenient and can be applied to different scenes.

[0046] Furthermore, the support assembly also includes a drive motor 31 and a plurality of connecting structures 32, the drive motor 31 is fixed to the top plate 21, the drive motor 31 has a drive shaft 311 extending horizontally, each of the connecting structures 32 includes a first connecting rod 321, a plurality of the first connecting rods 321 are connected in sequence along the horizontal direction, and the first connecting rod 321 close to the drive motor 31 is fixedly connected to the drive shaft 311; the shaft 3a includes a plurality of first connecting rods 321; and the suspension portion includes at least one first connecting rod 321. That is, the shaft rod 3a can be obtained by splicing a plurality of the first connecting rods 321, and the number of the first connecting rods 321 is selected according to the actual working conditions. It can be understood that the portion of the shaft rod 3a protruding from the top plate 21 forms the suspension portion, and therefore, the suspension portion can be composed of a single first connecting rod 321 or a plurality of first connecting rods 321. Specifically, when an accident occurs in a single lane, a plurality of connecting wires 41 can be installed on the first connecting rod 321 of the corresponding lane, and when there are two lanes separated or adjacent, the connecting wires 41 are installed on a plurality of first connecting rods 321. Preferably, the length of each first connecting rod 321 is adapted to the width of the lane.

[0047] The present invention does not limit the connection and matching mode of each first connecting rod 321, and can be connected by thread connection or clamp connection. Considering that the width of the lane is long, the length of a single first connecting rod 321 is also long. In order to improve the convenience of disassembly and assembly, in this embodiment, the opposite end faces of each two adjacent first connecting rods 321 form a matching surface, one of which is provided with a groove 3212, and the other is provided with a protrusion 3211, and the protrusion 3211 and the groove 3212 are plugged and fixed. It can be understood that the protrusion 3211 and the groove 3212 can be set to a regular or irregular shape, so as to ensure that each first connecting rod 321 can rotate synchronously after being plugged. When the protrusion 3211 and the groove 3212 are both circular, a reasonable gap should be set to prevent the adjacent first connecting rods 321 from rotating relative to each other, and cannot be synchronously driven by the drive motor 31. In this embodiment, the protrusion 3211 and the groove 3212 are both square.

[0048] In order to protect and support the first connecting rod 321, in one embodiment, please refer to Figure 3 to Figure 4, each of the connecting structures 32 also includes a cover shell 322, each of the cover shells 322 has a first end and a second end that are opposite to each other in the horizontal direction, and a slot 3221 is formed at the second end of each of the cover shells 322 for plugging and matching with the first ends of the adjacent cover shells 322, and each of the cover covers has a accommodating cavity 3222. Among the multiple connecting structures 32, the bottom wall of at least one of the accommodating cavities 3222 is provided with a plurality of through holes 3222a; each of the first connecting rods 321 is rotatably installed in the accommodating cavity 3222, and the two ends of each of the first connecting rods 321 can pass through the corresponding accommodating cavity 3222 to be exposed to the outside world; the multiple connecting wires 41 pass through the accommodating cavity 3222 through the multiple through holes 3222a. The cover shell 322 plays a protective role. At the same time, the two adjacent cover shells 322 can achieve a stable connection through plug-in cooperation, maintain good consistency, provide support, and avoid the tilting of the ends and instability caused by the excessive length of the multiple first connecting rods 321 when connected separately. The setting of the multiple through holes 3222a realizes the passage of the connecting wire 41, that is, when the shaft rod 3a rotates, the connecting wire 41 can be rolled up in the accommodating cavity 3222, and the magnet 42 will be blocked and remain outside the cover shell 322. When unfolding again, the connecting wire 41 can be smoothly unfolded by the traction of the magnet 42, and the stability is better.

[0049] It should be noted that, in this embodiment, the slot 3221 is of non-closed design, and a notch is provided on the lower wall of the slot 3221 to prevent assembly difficulties caused by processing errors.

[0050] Considering the strong wind, in this embodiment, the upper wall of each slot 3221 is provided with a threaded hole, and each connection structure 32 further includes a locking bolt 323, which passes through the threaded hole to be tightly abutted against the outer surface of the first end of the adjacent cover 322. That is, under the premise of plug-in matching, the fastening bolt is added to perform rigid positioning, further strengthening the connection matching of each cover 322, and preventing shaking or even loosening due to the gap in the plug-in matching in strong wind.

[0051] Since one end of the shaft 3a is connected to the drive shaft 311, and the drive shaft 311 is suspended on the top plate 21, in order to prevent the drive shaft 311 from being deformed and broken due to excessive force, please refer to Figure 1 and Figure 5 A shell may also be provided on the surface of the drive shaft 311 . In this case, the structure of the shell may be designed to be consistent with the cover shell 322 , and the bottom may contact the top plate 21 , thereby providing protection for the drive shaft 311 and providing support on the top plate 21 .

[0052] It should be noted that the driving shaft 311 and the first connecting rod 321 can also be connected by a concave-convex plug-in method, that is, a groove adapted to the protrusion 3211 is provided at the end of the driving shaft 311, so that multiple first connecting rods 321 can be assembled arbitrarily, with better versatility.

[0053] Moreover, among the plurality of connection structures 32, at least one of the cover shells 322 is provided with an audible and visual alarm 324 at its upper end. The audible and visual alarm 324 is installed at the top of the entire device, so that vehicles behind can quickly detect accidents ahead, thereby increasing the distance of early warning.

[0054] Specifically, a battery can be installed in the inner cavity of the base 1, and the battery is electrically connected to the sound and light alarm 324. Similarly, the battery can also be electrically connected to the drive motor 31 to provide power.

[0055] The present invention does not limit the specific structure for realizing the lifting of the top plate 21, which may be a hydraulic cylinder, an electric push rod, a worm gear, etc. In this embodiment, the lifting mechanism 2 includes a scissor mechanism 22, the fixed end of the scissor mechanism 22 is arranged on the base 1, and the movable end is fixedly connected to the top plate 21. The mechanism has good load-bearing performance, and the lifting stroke is larger and the stability is better.

[0056] Please refer to Figure 6 The surface of each magnet 42 is covered with a silicone sleeve 421. This can weaken the magnetism of the magnet 42, making it easier for the magnets 42 to separate from each other. When a vehicle accidentally hits the warning wall, the multiple magnets 42 can separate from each other under the impact force. The silicone sleeve 421 is made of a relatively soft material and will not cause significant damage to the vehicle.

[0057] Furthermore, the bottom of the base 1 is provided with a plurality of universal wheels distributed along the circumference of the base 1 to facilitate the overall transportation and movement of the equipment.

[0058] Please refer again Figure 1 The side of the base 1 is provided with a detachably connected counterweight 11. To increase the overall stability and prevent the device from tipping over to the warning wall, the counterweight 11 of different weights can be selected for installation according to the length of the shaft 3a.

[0059] It should be noted that the above two related technical features, the universal wheel and the counterweight 11, can be set either one or at the same time. In this embodiment, they are set at the same time.

[0060] In addition, a handle is provided on the base 1, and the handle can be directly set on the counterweight block 11, so that it is easy to dismantle, replace, extract and move when replacing the counterweight block 11.

[0061] Furthermore, the material of each of the connecting lines 41 is a transparent fishing line, which has good toughness and low cost. The transparent material can provide a good field of vision for the rear vehicle, so that the accident area can be observed. Preferably, the connecting line 41 is a No. 4.0 fishing line.

[0062] Considering the safety of driving at night, the warning wall is used to spray reflective paint to form warning slogans, which are convenient for night drivers to find in time.

[0063] It should be noted that the above two related technical features, the material selection of the connecting line 41 and the selection of the paint of the warning slogan, can be set either alone or simultaneously. In this embodiment, they are set simultaneously.

[0064] It is understandable that the warning device mentioned in the present invention is not limited to traffic accident warning, but can also be used in scenes such as road construction. The following uses highway warning as an example for explanation:

[0065] The equipment is transported to 150 meters behind the accident site, and the base 1 is placed on the outermost side of the outer lane near the accident lane, and rotated by the universal wheel at the bottom of the base 1. During assembly, the length direction of the shaft 3a is in the same direction as the driving direction of the lane to avoid affecting traffic. At the beginning of assembly, a plurality of the connecting wires 41 are wound around the corresponding first connecting rods 321 and placed inside the accommodating cavity 3222. It should be understood that the cover shell 322 is made of non-magnetic metal material to avoid magnetic attraction with each of the magnets 42. Subsequently, the two cover shells 322 without the connecting wires 41 are assembled in sequence, and the cover shell 322 of the connecting structure 32 at the end is assembled. The first connecting rod 321 is inserted into the housing, and the protrusion 3211 of the first connecting rod 321 is inserted into the groove of the driving shaft 311, and then the locking screw is used to tighten and fix the first connecting rod 321. The plurality of connecting structures 32 are connected and assembled with each other in the above method. After the assembly is completed, the scissor mechanism 22 is started to drive the top plate 21 to rise, and the shaft 3a is lifted. Then the base 1 is controlled to rotate the device as a whole by 90°, so that the length direction of the shaft 3a is perpendicular to the driving direction of the vehicle. Then the driving motor 31 is started and drives the plurality of the first connecting rods 321 to rotate synchronously. Under the gravity of the magnet 42, the plurality of connecting wires 41 are unfolded to form the warning wall. After the survey is completed and the lane is cleared, the driving motor 31 is powered on again to roll up the warning wall. After the storage is completed, the device is rotated again so that the length direction of the shaft 3a is in the same direction as the driving direction of the vehicle, and then the device is dismantled.

[0066] Compared with the prior art, the beneficial effects of the present invention are:

[0067] First, when in use, the connecting lines 41 are arranged along the width direction of the road, and multiple connecting lines 41 form a warning wall structure, which increases the visible area of ​​the rear vehicles and warns the vehicles farther away. Warning slogans are painted on the connecting lines 41 to remind the rear vehicles of the accident ahead. The warning slogans are made of reflective material, which is convenient for night drivers to find them in time. The multiple magnets 42 are magnetically attracted to each other, so that the bottom of the adjacent connecting lines 41 is kept stable after forming the curtain wall structure, preventing the connecting lines 41 from being scattered due to being blown in windy weather. Multiple first connecting rods 321 are assembled with each other to achieve a longer shaft rod 3a, thereby meeting the size requirements of the warning wall of multiple lanes.

[0068] Second, the driving shaft 311 of the driving motor 31 can drive the multiple first connecting rods 321 to rotate synchronously, thereby realizing the winding, storage or release of the connecting line 41. The multiple cover shells 322 are connected by plug-in and bolt-fastening, which is convenient for multi-section assembly.

[0069] Third, the sound and light alarm is installed at the top of the equipment and is connected to the battery in a conventional electrical manner, so that vehicles behind can quickly detect accidents ahead and increase the warning distance.

[0070] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
