The first anti-theft mechanism 130 and the second anti-theft mechanism 140 are configured to be sequentially unlocked, that is, when the inner well lid of the inspection well needs to be opened, the first anti-theft mechanism 130 needs to be unlocked first, and after the main inner well lid 110 is opened, the second anti-theft mechanism 140 is unlocked, so that the auxiliary inner well lid 120 can be opened.
The first anti-theft mechanism 130 and the second anti-theft mechanism 140 are configured to be locked in reverse order, that is, when the inner well lid of the inspection well needs to be closed and locked, the auxiliary inner well lid 120 needs to be closed first, the second anti-theft mechanism 140 is locked, the main inner well lid 110 is closed later, and the first anti-theft mechanism 130 is locked, so that the closing and locking of the inner well lid of the inspection well can be completed.
By arranging the first anti-theft mechanism 130 and the second anti-theft mechanism 140 for the main inner well lid 110 and the auxiliary inner well lid 120 respectively and configuring the first anti-theft mechanism 130 and the second anti-theft mechanism 140 to be sequentially unlocked, an anti-theft effect can be achieved, and the first anti-theft mechanism 130 and the second anti-theft mechanism 140 are configured to be locked in reverse order, so that the situation that the inner well lid is forgotten to be locked in the process of closing the inner well lid can be avoided.
Referring to fig. 1, 2 and 3, according to some embodiments of the present application, the primary manhole cover 110 and the secondary manhole cover 120 each optionally include an outer surface located outside of the manhole, an inner surface located inside of the manhole, the first anti-theft mechanism 130 is unlocked from the outer surface of the primary manhole cover 110, and the second anti-theft mechanism 140 is unlocked from the inner surface of the secondary manhole cover.
As shown in fig. 1 and 2, the first anti-theft mechanism 130 is provided at the inner surface of the main manhole cover 110, and an unlocking switch thereof penetrates the main manhole cover 110 toward the outside of the manhole so as to unlock the first anti-theft mechanism 130 from the outer surface. In this embodiment, the first anti-theft mechanism 130 is a mechanical lock, the keyhole of which is located on the outer surface of the main manhole cover 110.
