As shown in fig. 1-10, the anti-opening structure for the sewer manhole cover comprises a wellhead end edge body 11 part and a manhole cover 1 part, wherein a ring of annular groove 1101 coaxial with the wellhead end edge body 11 is arranged around the top surface of the wellhead end edge body 11, a plurality of arc-shaped connecting ribs 16 with circular cross sections and fixed in the groove 1101 are arranged in the groove 1101, the connecting ribs 16 extend along the circumferential direction of the groove 1101, and each connecting rib 16 is provided with a jack 1601 along the axial direction; the well lid 1 comprises a circular ring-shaped lid body 101 and an inserting cylinder 102 axially extending out along the inner wall of an inner hole of the lid body 101, the inserting cylinder 102 is used for being inserted into a well 1100 during installation, a plurality of arc-shaped pipelines with the same number as the connecting ribs 16 are arranged on the end surface of one side of the cover body 101 facing the inserting cylinder 102, each pipeline is internally provided with a section of arc-shaped reinforcing steel bar 13 which can extend out of one end of the pipeline, when the plugging cylinder 102 is plugged into the wellhead end edge body 11, all the arc-shaped pipelines are installed in the groove 1101, each section of connecting rib 16 is correspondingly positioned between a pair of adjacent arc-shaped pipelines, so that one end of the steel bar 13 can pass through the corresponding insertion hole 1601 of the connecting rib 16 and extend into another pipeline when sliding out of the pipeline, and the insertion hole 1601 in the connecting rib 16 is preferably a conical hole arranged along the moving direction of the steel bar entering into another pipeline, so as to guide the end of the steel bar 13 entering into the connecting rib 16.

The well lid further comprises a lock cylinder component positioned in the well lid 1, the lock cylinder component is positioned right above the groove 1101, a lock sleeve 4 at the top of the lock cylinder component is positioned in a strip-shaped hole 1011 of a sealing plate 3 embedded in the lid 101 in a horizontal manner and can move along the strip-shaped hole 1011, a convex frame 6 which is communicated with an inner hole of the lock sleeve 4 for inserting a key is fixedly connected with the lower part of the lock sleeve 4, the convex frame 6 comprises a circular pipe part and a flange which is circular and extends towards the center of a circle, the lock cylinder component further comprises a first plug pin 7 which can move up and down, a steel bar 13 and the steel bar 13 are provided with an occlusion hole which can be matched with the lower end of the first plug pin 7, a plurality of convex side walls of the plug-in sheet 702 are arranged on the side wall at the top end of the first plug pin 7, a circular plate 5 is arranged right above the first plug pin 7, a through hole 501 which can be used for the first plug pin 7 to take one end of, the top end face of the first bolt 7 is provided with a keyhole 703, and the circular plate 5 is movably positioned in the convex frame 6 and cannot slide out of the convex frame 6 under the action of a flange when moving downwards.

A circular shaft shoulder 701 is arranged on the first pin 7 and below the convex frame 6, the bottom end of the first pin 7 penetrates through a bar-shaped through hole 501 of a backing plate 8 horizontally arranged in the shell, the shaft shoulder 701 is connected with the upper surface of the backing plate 8, a pair of supporting springs 9 are respectively arranged at two ends of the backing plate 8 along the length direction of the bar-shaped through hole 501, so that the backing plate 8 is supported, when a key is inserted into a lock hole 703 to screw the first pin 7 to a certain angle, the top end of the first pin 7 and the inserting sheet 702 are upwards penetrated through the through hole 501 under the action of the supporting springs 9 by the first pin 7, and at the moment, the first pin 7 is separated from the occlusion hole on the reinforcing steel bar 13.

In use, the well lid 1 is inserted into the well 1100 by positioning the insertion tube 102 portion, so that the corresponding arc-shaped pipe 12 is located in the groove 1101 on the wellhead end edge body 11, and each connecting rib 16 is located between two adjacent arc-shaped pipes 12. When the first bolt 7 is engaged with the steel bar 13, the well lid 1 is locked on a well head, if the engagement between the first bolt 7 and the steel bar 13 needs to be disconnected, a key needs to be inserted downwards into the lock sleeve 4 and then enters the through hole 501 of the circular plate 5 in the convex frame 6, and then the key is inserted into the keyhole 703 at the top end of the first bolt 7 so as to twist and rotate the first bolt 7, so that the corresponding insert sheet 702 at the top end of the first bolt 7 is aligned with the corresponding hole on the through hole 501, and the top end of the first bolt 7 with the insert sheet 702 is ejected out of the through hole 501 of the circular plate 5 under the jacking action of the supporting spring 9, at the moment, the well lid 1 is unlocked and can be taken down from the well. Correspondingly, to lock the well lid 1 again, a key needs to be inserted into the keyhole 703 of the first bolt 7 and drive the first bolt 7 to move to a position corresponding to the engagement hole on the steel bar 13 along the strip-shaped hole 1011 of the sealing plate 3 and press the first bolt 7 downwards, so that the first bolt 7 is located below the circular plate 5, the key continues to be held to rotate after the first bolt 7 is inserted into the engagement hole of the steel bar 13, the insertion piece 702 of the first bolt 7 is staggered with the corresponding hole of the through hole 501 on the circular plate 5, so that the top end of the first bolt 7 is connected with the bottom end face of the circular plate 5 under the jacking force of the supporting spring 9, the engagement connection between the first bolt 7 and the steel bar 13 can be recovered, and the well lid 1 is locked on the well head again.

Further, one end of the steel bar 13 is connected with a light return spring 15 in the arc-shaped pipe 12, and the other end of the steel bar passes through the insertion hole 1601 of the connecting rib 16 and then extends into the adjacent arc-shaped pipe 12. So that each time the reinforcement bar 13 is snapped off the first latch 7, the snap-in hole can be returned to a predetermined position so that the first latch 7 can be quickly aligned and inserted down into the snap-in hole for quick locking.

Further, the apron 2 that a steel sheet was made is covered over the bar hole 1011 of shrouding 3, apron 2 is the bottle lid form and imbeds on the well lid 1 and get up first bar hole protection, is equipped with the pull ring on the outside cylinder lateral wall of apron 2, plays the guard action to the lock core part, and is convenient for take off apron 2.
