[0001] The utility model relates to the technical field of municipal manhole covers, in particular to a municipal manhole cover damage warning device. Background Art

[0002] The manhole covers on the road are an important part of municipal engineering. Since the manhole covers are easily damaged after long-term use, or the manhole covers need frequent maintenance and repair, which often takes a certain amount of time, it is necessary to use guardrails to block the manhole covers to serve as a warning, so as to ensure that vehicles will not run over the manhole covers under maintenance.

[0003] For example, the patent website discloses a municipal construction protection device (publication number: CN211448059U). In order to ensure that the driver in the car can observe the device, the device frame is set very high. The staff need to flip through this high frame when entering and exiting the well, which is very inconvenient and dangerous. Therefore, technical personnel in this field have proposed a municipal manhole cover damage warning device. Utility Model Content

[0023] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the relevant content and are not intended to limit the present disclosure. It should also be noted that, for ease of description, only the portions relevant to the present disclosure are shown in the accompanying drawings.

[0028] Figure 5 This is a schematic diagram of the disassembled structure of the fixing mechanism of a municipal manhole cover damage warning device;

[0029] like Figure 1-4 As shown, a municipal manhole cover damage warning device disclosed in the present invention may include: a fixing mechanism and a warning bar mechanism and other components;

[0030] like Figure 1-4 As shown, the warning bar mechanism includes a main rod 1, a cavity 2, a slider 3, a spring 4, a secondary rod 5, an upper ring 6, a lower ring 7, and a warning tape 15;

[0031] Multiple main rods 1 are evenly mounted on the upper surface of the lower ring 7. Each cavity 2 is opened inside the corresponding main rod 1. Each slider 3 is slidably disposed in the corresponding cavity 2. Each spring 4 is disposed inside the corresponding cavity 2 and below the slider 3. Each secondary rod 5 is mounted on the upper surface of the corresponding slider 3 and extends to the outside of the main rod 1. The upper ring 6 is mounted on the upper ends of all secondary rods 5. The warning tape 15 is mounted on the side of all main rods 1.

[0032] The warning bar mechanism can play a warning and blocking role. When the staff needs to look through the warning bar, they only need to press the upper ring 6 to move the corresponding slider 3 downward through each auxiliary rod 5. Each downward-moving slider 3 will compress the spring 4 directly below until the upper ring 6 drops to a height that the staff can directly cross over. After that, the staff can directly cross the warning bar mechanism without having to look through it, which is more convenient and will not be dangerous. After the crossing is completed, the downward pressure on the upper ring 6 is released, and then all the compressed springs 4 rebound and drive the auxiliary rods 5 to rise until the position is restored, so that the warning bar mechanism structure can be restored;

[0033] like Figure 1-4As shown, the fixing mechanism includes a square tube 8, a receiving slot 9, a slide rod 10, an adjustment hole 11, a positioning hole 12, a pin 13, and a magnetic block 14;

[0034] A plurality of square tubes 8 are evenly mounted on the upper surface of the lower ring 7 and are located on one side of the main rod 1. Each receiving groove 9 is provided at the end of the corresponding square tube 8. Each slide rod 10 is slidably provided in the corresponding receiving groove 9. Each group of multiple adjustment holes 11 is evenly provided on the upper surface of the corresponding slide rod 10. Each positioning hole 12 is provided on the upper surface of the corresponding square tube 8 and is aligned with a positioning hole 12. Each pin shaft 13 is provided between the corresponding positioning hole 12 and the adjustment hole 11 aligned therewith. Each magnetic block 14 is provided on the lower surface of the corresponding slide rod 10 located outside the square tube 8.

[0035] When the manhole cover is damaged or the staff is working underground, the device is placed against the metal outer ring of the manhole cover, and the four magnetic blocks 14 of the device are adsorbed on the metal outer ring of the manhole cover to fix the device. The device can be fixed to the outside of the manhole cover and then used to warn the position.

[0036] When installing the device, after the lower ring 7 is aligned with the center of the manhole cover, the magnetic block 14 is not directly above the outer ring of the manhole ring. Pulling out the pin 13 can release the fixation of the slide bar 10, and then pulling the slide bar 10 outward or pushing it inward drives the magnetic block 14 to move until the magnetic block 14 moves to directly above the outer ring of the manhole cover. Then fine-tune the slide bar 10 to align the positioning hole 12 with the nearest adjustment hole 11, and then insert the pin 13 between the positioning hole 12 and the adjustment hole 11 aligned with it, and re-fix it. Repeat these operations to adjust the position of the other magnetic block 14. After adjustment, the magnetic block 14 is directly above the outer ring of the manhole cover. Then all the magnetic blocks 14 can be adsorbed on the outer ring of the manhole cover to fix the device on the outside of the manhole cover.
