AI Technical Summary
Technical Problem
The manhole covers at the entrances of existing cable tunnels are easily broken by heavy vehicles, causing pedestrians to fall into the manholes and posing a life-threatening danger.
Method used
A cable tunnel manhole device was designed, comprising a manhole body, a fixing block, a circular mounting plate, a placement plate, and a manhole cover. Through the cooperation of a circular plug rod and a butterfly spring, the placement plate is ensured to flip over and cover the manhole when the manhole cover breaks, preventing pedestrians from falling in.
Benefits of technology
When a manhole cover breaks, a placement plate automatically flips over to cover the manhole opening, protecting pedestrians from falling into cable tunnels and ensuring their safety.

Abstract
The utility model relates to cable tunnel wellhead technical field discloses a cable tunnel wellhead device, including wellhead body, four fixed blocks that are circumferentially distributed are set up in wellhead body inner chamber, the circular mounting plate is placed on four fixed blocks top, the setting plate is set up on the circular mounting plate, the wellhead body one side is provided with the circular slot. The utility model discloses, when the well lid is covered on the wellhead body, the circular plug-in rod can be vertically moved down at this moment, so the L-shaped mounting plate can be vertically moved down, when the L-shaped mounting plate vertically moves down, the L-shaped mounting plate will lose the spacing of the setting plate at this moment, so the setting plate can be turned over to the circular mounting plate, thereby ensuring that when the well lid breaks, the pedestrian steps on it, the falling situation occurs at this moment, because the setting plate is arranged below, so the setting plate can ensure that the pedestrian will not fall into the well, ensuring the life safety of the pedestrian.
