Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figure 5 , Figure 6, An embodiment provided by the present utility model: a new type of anti-theft device for municipal manhole covers, including a main cover 1, which covers the wellhead, protects the facilities inside the well, and prevents objects or personnel from falling into the well. The bottom of the main cover 1 is detachably connected with a bottom cover 2, which provides additional protection and functional support. It is connected to the main cover 1 through a detachable connection, facilitating maintenance and replacement. A plurality of first water inlet holes 3 are opened on the inner wall of the bottom cover 2, which helps to keep the manhole cover area dry and reduce the potential damage of water to the structure. It allows the accumulated water inside the manhole cover to be discharged, preventing safety hazards or corrosion caused by water accumulation. A transmission component with shrinkage ability is fixedly connected to the top of the bottom cover 2, and a spring 15 is sleeved outside the transmission component, providing elastic support and reset function. A second rotating shaft 9 is rotatably connected to the inner wall of the transmission component, which is responsible for converting the power of the transmission component into rotational motion. A first connecting block 4 is rotatably connected to the outside of the second rotating shaft 9, transmitting the rotational force, which may directly act on the rotation or movement of the manhole cover. A second connecting block 10 is rotatably connected to the outside of the second rotating shaft 9, and a sliding column 11 is slidably connected to the inner wall of the second connecting block 10, which is used to adjust the opening and closing angle or position of the manhole cover to ensure the smooth operation of the manhole cover. It is used to adjust or fix the position of the manhole cover to achieve more precise control. A wire box 12 is fixedly connected to the outside of the transmission component. It is used to store and protect wires.

[0034] Refer to Figure 2 , Figure 3 , Figure 5 , The transmission component includes a motor box 5, which contains a motor and related driving devices and is responsible for providing power. The output end of the motor box 5 is fixedly connected with a first rotating shaft 6, which has a precise bearing system to reduce friction and improve the movement efficiency. A first connecting rod 7 is rotatably connected to the outside of the first rotating shaft 6, which converts the rotational motion of the driving source into the linear or angular motion of the connecting rod, and then drives other components. A rotating rod 8 is fixedly connected to the outside of the first connecting rod 7, which is used to adjust or control the movement of other mechanical components connected to it. The outside of the motor box 5 is fixedly connected to the top of the bottom cover 2, and two connecting columns 13 are rotatably connected to the inner wall of the main cover 1, which are used to ensure the structural stability and position fixation of the main cover 1. A plurality of elastic columns 14 are fixedly connected to the top of the bottom cover 2, which provides the necessary elastic supporting force to maintain the distance between the partition 17 and other components and absorb the impact generated by the movement. A fixing block 16 is fixedly connected to the outside of the first connecting rod 7, which allows the sliding column 11 to move freely in a specific direction while ensuring its stability. The outside of the sliding column 11 is slidably connected to the inner wall of the fixing block 16, and a partition 17 is fixedly connected to the inner wall of the main cover 1, which is used to install other components or reduce the weight of the partition 17. The tops of the plurality of elastic columns 14 are fixedly connected to the bottom of the partition 17, and two hollow grooves 18 are opened on the inner wall of the partition 17, and a top cover 19 is fixedly connected to the top of the main cover 1. It prevents dust or sundries from entering and protects the internal components at the same time.

[0035] Refer to Figure 1 ,Figure 2 , Figure 5 , multiple anti-slip grooves 20 are provided on the inner wall of the top cover 19 to prevent people from sliding on the surface, thereby improving safety and stability. Multiple drain holes 21 are provided on the inner wall of the top cover 19 to prevent liquid accumulation from affecting the performance of the device or causing corrosion. Nuts 22 are threadedly connected to the bottoms of the two connecting columns 13 to enhance the stability of the overall structure. A rotating assembly for providing cleaning ability is rotatably connected to the inner wall of the top cover 19, which can effectively clean the inner wall of the top cover 19 and its nearby areas to ensure that the device remains clean for a long time. The bottom of the main body cover 1 is detachably connected to an inner tube 26 to ensure that the inner tube 26 is not easily loosened during use and at the same time allows the inner tube 26 to be firmly fixed. A locking hole 27 is provided on the inner wall of the inner tube 26. The rotating assembly includes a rotating cap 23. The bottom of the rotating cap 23 is fixedly connected to a rotating frame 24. A plurality of brush plates 25 are fixedly connected to the outside of the rotating frame 24 to ensure that the cleaning requirements of the inner wall of the top cover 19 can be fully covered during rotation to remove dirt or impurities. The outside of the rotating cap 23 is rotatably connected to the inner wall of the top cover 19.

[0036] Compared with some devices in the prior art, the above content improves the anti-theft performance and convenience during maintenance of the device, and can prevent the device from being blocked, resulting in poor drainage.

[0037] Working principle: The operator connects the driving source inside the motor box 5 to the wires inside the wire box 12, and then starts the transmission assembly to make the rotating rod 8 rotate. The rotation of the rotating rod 8 drives the second rotating shaft 9 to rotate, so that the second connecting block 10 makes a small upward contraction movement. The sliding column 11 connected inside the first connecting block 4 also follows to make a sliding movement. Through the adaptation combination with the locking hole 27 provided on the inner wall of the inner tube 26, it causes external personnel to be unable to move the manhole cover.

[0038] When there is a large amount of sediment or garbage, the drain holes 21 will be blocked, resulting in a decline in the drainage function. Therefore, the operator rotates the rotating cap 23 to drive the rotating frame 24, so that the brush plates 25 scrape the drain holes 21 to clean the blocked garbage. When people or vehicles pass by the cover device, the elastic columns 14 can be used for buffer adjustment to appropriately reduce the influence of the outside world on the device.

[0039] 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 recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
