AI Technical Summary
Existing manhole covers require a long extension stroke to open, resulting in poor control performance and reduced reliability of the electro-hydraulic rod. At the same time, the limited opening angle restricts the space for downhole operations.
Design an intelligent manhole cover comprising a square hollow support frame, an internal track, a horizontal conveying device, and four vertically arranged lifting rods. The lifting rods raise the support frame and move the outer frame of the rollers horizontally. Combined with the horizontal conveying device, the manhole cover can be opened and closed, ensuring that the activity space is not obstructed.
It enables labor-saving opening of manhole covers, provides a larger working space, facilitates downhole operations, and improves the reliability and control performance of the electro-hydraulic rod.

Abstract
Claims
1. A smart manhole cover, characterized by: The system includes a square, hollow support frame, a track embedded inside the support frame, a horizontal conveying device embedded at the upper end of the support frame, and four lifting rods vertically arranged at the four corners of the lower end of the support frame. The horizontal conveying device has a manhole cover placement position. The track is equipped with a cylindrical roller frame that can move horizontally along the track. The cylindrical roller frame is equipped with multiple parallel and spaced cylindrical rollers. When the cylindrical roller frame moves horizontally along the track, it moves the cylindrical rollers out of the support frame. The four lifting rods can be controlled synchronously.
2. The intelligent well lid according to claim 1, characterized in that: The top of the lifting rod is detachably connected to the bottom of the support frame.
3. The intelligent well lid according to claim 1, wherein: One end of the track is provided with a limiting part for restricting the position of the manhole cover.
4. The intelligent manhole cover of claim 1, wherein: The horizontal height difference between the horizontal conveying device and the outer frame of the cylindrical roller does not exceed 10cm.
5. The intelligent manhole cover of claim 1, wherein: The horizontal conveying device is a conveyor belt, and the upper surface of the conveyor belt is flush with the upper surface of the support frame.
6. The intelligent manhole cover of claim 1, wherein: The support frame is provided with a first locking part, a manhole cover monitor, a controller and an radio frequency module. The manhole cover is provided with a second locking part that cooperates with the first locking part. The first locking part is electrically connected to the manhole cover monitor, the manhole cover monitor is electrically connected to the controller, and the controller is electrically connected to the radio frequency module.
7. The intelligent manhole cover of claim 6, wherein: The support frame is equipped with a height measuring sensor, which is electrically connected to the controller. The lifting rod is controlled by the controller.
