Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Please refer to fig. 1-5, in an embodiment of the present invention, a manhole cover structure for municipal works, includes a fixing base 1 and a housing 2, a dovetail groove 101 is provided in the fixing base 1, and a second mounting port 105 connected with the dovetail groove 101 is provided on the upper surface, a connecting block 3 capable of sliding in the dovetail groove 101 is fixedly installed on the outer wall of the housing 2, the connecting block 3 is slightly smaller than the second mounting port 105, a plurality of water holes 201 are provided on the housing 2, and a handle 8 is fixedly installed on the housing. During the installation, at first with fixing base 1 fixed mounting in the sewer top, rethread handle 8 removes fixing base 1 top with the shell, makes connecting block 3 correspond with second installing port 105 and puts into, rotates shell 2, makes connecting block 3 hide in dovetail 101 to shell 2 is fixed in fixing base 1.

In order to further ensure that the housing 2 cannot be separated from the fixing seat 1, a first limiting hole 104 is formed in the fixing seat 1, the first limiting hole 104 is connected with the dovetail groove 101, a second limiting hole 301 is formed in the connecting block 3, and the second limiting hole 301 corresponds to the first limiting hole 104 and is fixed through a pin shaft. When the housing 2 is installed in the fixing seat 1, the housing 2 is rotated, so that the second limiting hole 301 corresponds to the first limiting hole 104, the pin shaft is inserted, and the connecting block 3 is prevented from sliding in the dovetail groove 101.

Considering that the fixing base 1 may be deviated by an external force when being used for a long time, the periphery of the fixing base 1 is provided with a plurality of anti-loosening members 7, and the anti-loosening members 7 are fixedly connected with the ground, so that the fixing base 1 is effectively prevented from moving.

The filter screen 4 is fixedly arranged in the cavity 106 of the fixed seat 1, and when the filter screen 4 prevents water flow in the sewer from overflowing, garbage in the sewer blocks the water hole 201 of the shell, and meanwhile, the garbage can be prevented from entering the sewer; furthermore, when the shell 2 is damaged due to accidents, the filter screen 4 can also be used as a last layer of protection screen to prevent people from falling into a sewer.

The utility model discloses a theory of operation is:
