[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0036] Referring to Figures 1-5 and Figure 8 , an embodiment provided by the present invention: A warning device for a municipal engineering road includes a counterweight block 1. The counterweight block 1 provides the stability of the entire device, ensuring that the device is not easily toppled during use. The top of the counterweight block 1 is fixedly connected to a storage case 2. The storage case 2 provides space protection for the winding and storage of the warning sign 7, preventing the warning sign 7 from being affected by the outside world when not in use. A winding component for winding is installed inside the storage case 2. The winding component is used to control the deployment and winding of the warning sign 7, facilitating operation and management. A warning sign 7 is provided inside the storage case 2. The warning sign 7 is used to provide road warning information to ensure the warning effect. The outer wall of the storage case 2 is rotatably connected to a first support rod 8. The first support rod 8 provides support for the deployment of the warning sign 7, ensuring that the warning sign 7 can maintain a stable position. The outer wall of the warning sign 7 is rotatably connected to a second support rod 9. The second support rod 9 further supports the warning sign 7, enabling it to remain firm when deployed and ensuring the clear display of information. The first support rod 8 is rotatably connected to one end of the second support rod 9. The connection between the first support rod 8 and the second support rod 9 provides flexibility for the deployment and storage of the warning sign 7, enabling the warning sign 7 to be easily deployed or wound. A locking component for locking is installed on the outer wall of the second support rod 9. The locking component ensures that the first support rod 8 and the second support rod 9 can be fixed in place when deployed, preventing them from moving under the action of wind or other external forces. A locking hole 10 is opened inside the first support rod 8. The locking hole 10 is used to cooperate with the locking component to achieve firm locking of the support rod;
[0037] The rewinding assembly includes a connecting shaft 3 which is fixedly connected inside the storage shell 2, providing the core support structure for the rewinding system. The outer wall of the connecting shaft 3 is rotatably connected with a shell 4 which is used to accommodate and protect the torsion spring 5 to ensure the stability of the rewinding operation. Inside the shell 4, there is a torsion spring 5 which provides the driving force for rewinding and automatically retracts the warning sign 7 through its elastic force. One end of the torsion spring 5 is fixedly connected inside the connecting shaft 3 to ensure that the torsion spring 5 can be reliably fixed on the axis and avoid displacement during use. The other end of the torsion spring 5 is fixedly connected inside the shell 4 to ensure that the force of the torsion spring 5 can be transmitted to the shell 4 to drive the rewinding of the warning sign 7. Inside the shell 4, there is a rotating shaft 6 which provides the rotation axis for the warning sign 7, enabling it to be flexibly deployed and rewound. One side of the warning sign 7 is fixedly connected to the outer wall of the rotating shaft 6. Through the fixed connection with the rotating shaft 6, the warning sign 7 can be smoothly rewound and deployed and remain in the correct position. The locking assembly includes a connecting plate 11. One end of the connecting plate 11 is rotatably connected to the outer wall of the second support rod 9. The connecting plate 11 provides the basic support structure for the locking assembly to ensure the smooth cooperation operation with the second support rod 9. Inside the connecting plate 11, there is a first limiting plate 12 which can be locked or released at an appropriate position through the sliding structure to achieve precise control of the support rod. Inside the first limiting plate 12, there is a locking column 13 which is the core component of the locking operation. One end of it realizes the fixation of the support rod through the cooperation with the locking hole 10. One end of the locking column 13 is rotatably connected with a pull ring 15 which provides convenience for manual operation. The user can easily perform the locking or unlocking operation through the pull ring 15. A first spring 14 is sleeved on the outer wall of the locking column 13 which is used to provide the reset elastic force for the locking column 13 to ensure that the locking column 13 can automatically reset after the unlocking operation is completed. One end of the first spring 14 is fixedly connected to one side of the first limiting plate 12, providing the fixing point of the spring to ensure that the reset force of the spring can be transmitted to the locking column 13. The other end of the first spring 14 is fixedly connected inside the connecting plate 11 to further ensure the stability of the spring and the effective transmission of the acting force. The locking column 13 passes through the locking hole 10. By passing through the locking hole 10, the locking column 13 can effectively fix the support rod to ensure that the warning device can be firmly and stably fixed after being deployed;
[0038] Specifically, the counterweight 1 is first firmly placed in a predetermined position to ensure that it does not move during operation. Subsequently, by gently pulling out the warning sign 7 on the device, one side of the warning sign 7 is reliably connected to the housing 4 through a rotating shaft 6, forming a flexible rotating structure. The housing 4 is connected to the storage housing 2 through a sturdy connecting shaft 3 to ensure the stability of the entire structure. At the same time, a torsion spring 5 is installed between the housing 4 and the connecting shaft 3 to provide appropriate resilience. During the process of pulling out the warning sign 7, the torsion spring 5 gradually accumulates elastic potential energy to prepare for subsequent automatic storage. When the warning sign 7 is fully unfolded, the first support rod 8 and the second support rod 9 naturally form a straight line to ensure the stable support of the warning sign 7. At this time, the connecting plate 11 on the second support rod 9 is accurately buckled on the first support rod 8 to ensure their close combination. At the same time, the locking column 13 at one end of the connecting plate 11 passes through the locking hole 10 to firmly lock the warning sign 7 in the unfolded position to prevent it from retracting under external force and ensure the warning effect. When storage is required, the operator can easily pull out the locking column 13 from the first support rod 8 through the pull ring 15 to unlock the warning sign 7. Subsequently, the connecting plate 11 and the first support rod 8 will be separated smoothly. The locking column 13 quickly resets under the tension of the first spring 14. At this time, the torsion spring 5 starts to function, driving the warning sign 7 to quickly retract and tightly wind around the outer wall of the rotating shaft 6, and the warning sign 7 quickly retracts into the interior of the storage housing 2, completing the storage process and achieving the effect of efficiently storing the warning sign 7.
[0039] Refer to Figure 6 and Figure 7, a positioning groove 21 is formed inside the storage case 2. The positioning groove 21 is used to provide guidance for the positioning pin 24 to ensure the accurate position of the support block 22 during installation and disassembly. A second limiting plate 16 is slidably connected inside the storage case 2. The function of the second limiting plate 16 is to limit the position of the installation pin 17 and unlock it through the release block 18 when necessary. A release block 18 is fixedly connected to the outer wall of the second limiting plate 16. The release block 18 is used for manual operation. By lifting the release block 18, the second limiting plate 16 is released, so that the installation pin 17 is unlocked. An installation pin 17 is fixedly connected to the bottom of the second limiting plate 16. The installation pin 17 is used to lock the support block 22 inside the storage case 2 when the brush bristles 25 are installed, ensuring that the support block 22 will not move or fall off during use. A telescopic rod 19 is arranged inside the storage case 2. The function of the telescopic rod 19 is to provide a telescopic force to push the second limiting plate 16 for locking and unlocking operations during the operation. A second spring 20 is sleeved on the outer wall of the telescopic rod 19. The second spring 20 pushes the telescopic rod 19 to maintain its initial position through elastic force, ensuring that the second limiting plate 16 is in a stable state when the release block 18 is not operated. One ends of the telescopic rod 19 and the second spring 20 are both fixedly connected inside the storage case 2. This fixed connection ensures that the telescopic rod 19 and the second spring 20 can provide stable elastic support during the operation. The other ends of the telescopic rod 19 and the second spring 20 are both fixedly connected to the top of the second limiting plate 16. Through this connection method, the second limiting plate 16 can move flexibly under the operation of the release block 18, so as to realize the unlocking and reset of the installation pin 17. A support block 22 is arranged inside the storage case 2. The function of the support block 22 is to support the brush bristles 25 and cooperate with the storage case 2 through the positioning pin 24 and the installation groove 23. Brush bristles 25 are fixedly connected to the outer wall of the support block 22. The brush bristles 25 are used to clean the surface of the warning sign 7 when the warning sign 7 is stored, keeping the warning sign 7 clean. A positioning pin 24 is fixedly connected to the bottom of the support block 22. The positioning pin 24 is slidably connected inside the positioning groove 21 to ensure the stable movement of the support block 22 during installation and disassembly. An installation groove 23 is formed inside the support block 22. The installation groove 23 is used to provide a locking position for the installation pin 17 to ensure the stable installation of the support block 22 inside the storage case 2;
[0040] Specifically, when the warning sign 7 is gradually retracted into the storage case 2, the bristles 25 on the storage case 2 with ingenious design will automatically contact the surface of the warning sign 7 and conduct a comprehensive cleaning of it. The bristles 25 can effectively remove the dust and debris attached to the warning sign 7, keep its surface clean, and ensure good visibility and clarity during the next deployment. The entire cleaning process is automatically completed without additional operations, greatly improving the convenience of use and the maintenance effect. When the bristles 25 need to be replaced due to long-term use, the operation is also very simple. Just gently lift the release block 18 upwards, and the mounting pin 17 can be lifted through the second limiting plate 16, so that the mounting pin 17 is separated from the support block 22 that supports the bristles 25. This design not only ensures the stable installation of the bristles 25, but also makes the replacement process more convenient. Then, the operator can smoothly take out the old bristles 25 together with the support block 22 from the storage case 2. The new bristles 25 are inserted and fixed by aligning the positioning pins 24 at the bottom of the support block 22 with the positioning grooves 21, ensuring that the bristles 25 are firmly installed in the designated position. After the installation process is completed, the elastic force of the second spring 20 causes the mounting pin 17 to automatically reset, pushing the mounting pin 17 to re-insert into the inside of the mounting groove 23, firmly locking the support block 22 in the storage case 2, ensuring that the bristles 25 will not loosen or fall off during use. The bristles 25 can not only automatically complete the cleaning task when the warning sign 7 is retracted, but also be conveniently replaced, greatly improving the maintenance efficiency and service life of the device, achieving the effect of automatically cleaning the warning sign 7 when it is retracted and being easy to replace the bristles 25.
[0041] Working principle: When using this warning device for municipal engineering roads, first place the counterweight block 1 at the required position, and then pull out the warning sign 7. One side of the warning sign 7 is connected to the housing 4 through a rotating shaft 6. The housing 4 is connected to the storage housing 2 through a connecting shaft 3. A torsion spring 5 is connected between the housing 4 and the connecting shaft 3. When the warning sign 7 is pulled out, the torsion spring 5 is energized. When the warning sign 7 is pulled out in place, the first support rod 8 and the second support rod 9 are in a straight line. Then, buckle the connecting plate 11 on the second support rod 9 onto the first support rod 8, so that the locking column 13 at one end of the connecting plate 11 penetrates into the locking hole 10 to lock, thereby locking the warning sign 7. When storage is required, pull out the locking column 13 from the first support rod 8 through the pull ring 15, and then separate the connecting plate 11 from the first support rod 8. The locking column 13 will reset under the tension of the first spring 14. Then, the warning sign 7 is driven by the torsion spring 5 to wind around the outer wall of the rotating shaft 6 and retract into the storage housing 2 for storage, achieving the effect of storing the warning sign 7. While the warning sign 7 is being stored in the storage housing 2, the surface of the warning sign 7 is cleaned by the brush hairs 25 on the storage housing 2. When it is necessary to replace the brush hairs 25, just lift the release block 18 upward, and then lift the mounting pin 17 through the second limiting plate 16, so that the mounting pin 17 is separated from the support block 22. Then, separate the brush hairs 25 from the storage housing 2 through the support block 22. Then, insert the new brush hairs 25 into the positioning groove 21 through the positioning pin 24 at the bottom of the support block 22. Then, the mounting pin 17 is reset by the tension of the second spring 20, and the mounting pin 17 is inserted into the mounting groove 23 to lock the support block 22 inside the storage housing 2, achieving the effect of automatically cleaning and facilitating the replacement of the brush hairs 25 when storing the warning sign 7.
[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
