Problems solved by technology
[0003] At present, the manhole covers used in municipal engineering are often round iron covers, and there are small water inlet holes on the manhole covers. When it rains, the rainwater will wash away a lot of sundries. The water inlet is blocked, and the existing manhole cover does not have the function of anti-blocking, so the water cannot be discharged normally, which brings great inconvenience to urban roads
The manhole cover design is simple and easy to be lifted, resulting in loss

The invention belongs to the technical field of well lids for municipal engineering, and particularly relates to a rotation-type burglarproof and anti-blocking well lid utilized in the municipal public engineering. The burglarproof and anti-blocking well lid utilized in the municipal public engineering comprises a well wall, a burglarproof mechanism, an anti-blocking mechanism and a well lid shell mechanism, wherein the burglarproof mechanism is installed on a well wall mounting surface and a well wall fixed structure mounting surface, the anti-blocking mechanism is arranged inside the well lid shell mechanism and is located at the upper side of the burglarproof mechanism, the well lid shell mechanism is installed on the well wall mounting surface and is located at the upper sides of the anti-blocking mechanism and the burglarproof mechanism; two sets of major spiral grooves and minor spiral grooves which are uniformly distributed on the well lid shell mechanism in the circumferential direction are the basis of achieving an anti-blocking function; the anti-blocking mechanism can achieve the function of automatically cleaning sundries when a well lid is clogged by the sundries; the complicated burglarproof mechanism can guarantee that the well lid cannot be easily stolen.
Description
[0001] Technical field [0002] The invention belongs to the technical field of municipal engineering manhole covers, in particular to a rotary anti-theft and anti-blocking manhole cover used in municipal public works. Background technique [0003] At present, the manhole covers used in municipal engineering are often round iron covers, and there are small water inlet holes on the manhole covers. When it rains, the rainwater will wash away a lot of sundries. The water inlet of the well is blocked, and the existing manhole cover does not have the function of anti-blocking, so the water cannot be removed normally, thereby bringing great inconvenience to urban roads. The design and structure of the manhole cover is simple, and it is very easy to be lifted and lost. [0004] The invention designs a rotary anti-theft and anti-blocking manhole cover used in municipal public works to solve the above problems. Contents of the invention [0005] In order to solve the above-mentione...
