A locking rod 411 that can be extended into the corresponding first locking hole 203 is provided on the moving plate 410. The locking rod 411 extends into the first locking hole 203 to realize the fixation of the cover body 110 in the installation cavity 200. A driving component for driving the moving plate 410 to move relatively is also provided in the moving cavity 400. An openable and closable drainage plate 111 is also relatively arranged at the upper end surface of the cover body 110.

[0028] In this embodiment, the manhole seat 100 is fixedly installed at the upper opening of the urban manhole, and is used to fix the cover body 110, so that the cover body 110 can be used to close the opening of the manhole, prevent external debris from entering the manhole, and prevent people from falling into the manhole and causing injuries;

[0029] Among them, through the arrangement of the first locking hole 203 and the locking rod 411, when the locking rod 411 extends into the corresponding first locking hole 203, the connection between the cover body 110 and the manhole seat 100 can be made more secure. Compared with the existing manhole cover, the cover body 110 in this embodiment will not easily detach from the manhole seat 100 when the pressure in the manhole suddenly increases, causing damage to pedestrians and vehicles on the road;

[0030] In this embodiment, when the locking rod 411 extends out of the corresponding first locking hole 203, the connection between the cover body 110 and the well seat 100 can be released, that is, the cover body 110 can be disassembled on the well seat 100. In order to facilitate the opening of the cover body 110, an opening hole 112 is provided on the upper end surface of the cover body 110. At this time, a tool such as a pry bar is inserted into the opening hole 112 to open the cover body 110 and enter the manhole for maintenance;

[0031] Wherein, by setting the driving assembly, the movement of the moving plate 410 can be controlled, thereby controlling the locking rod 411 to extend into or out of the corresponding first locking hole 203;

[0032] In this embodiment, the well seat 100 is made of steel fiber concrete, which has the characteristics of high strength and good bearing capacity, thereby making the well cover have high bearing capacity;

[0033] Among them, through the openable and closable setting of the drainage board 111, when the rainfall outside is heavy and too much rainwater gathers on the street, affecting the passage of pedestrians, the drainage board 111 can be opened to expand the drainage capacity, so that the rainwater gathered on the street can be discharged into the manhole in time, which is convenient for pedestrians to pass and more applicable.

[0034] like Figure 2-Figure 4 As shown, in this embodiment, the driving assembly includes a first driving rod 420 threaded through the corresponding moving plate 410, and the first driving rod 420 can be rotatably installed in the moving cavity 400. The moving cavity 400 has a moving groove 401 at the opposite side wall, and the two ends of the moving plate 410 are provided with a slider located in the corresponding moving groove 401 and moving. The first driving rod 420 is rotated to drive the locking rod 411 to extend into or out of the corresponding first locking hole 203.

[0035] In this embodiment, the two ends of the movable plate 410 are limited by the movable groove 401 through the matching arrangement of the slider and the movable groove 401. When the first driving rod 420 that screws through the movable plate 410 rotates clockwise, the movable plate 410 moves away from each other along the movable groove 401, thereby driving the locking rod 411 to extend into the corresponding first locking hole 203, thereby fixing the cover body 110 in the well seat 100. When the first driving rod 420 is rotated counterclockwise, the movable plate 410 moves closer to each other along the movable groove 401, thereby driving the locking rod 411 to extend out of the corresponding first locking hole 203, thereby releasing the fixation of the cover body 110 in the well seat 100. At this time, the cover body 110 can be taken out to enter the manhole for inspection;

[0036] In actual use of this embodiment, a first locking hole 203 and a second locking hole 211 are provided on the side wall of the movable cavity 400 correspondingly. The locking rod 411 can move in the corresponding second locking hole 211, and the second locking hole 211 can also play a guiding role to ensure that the locking rod 411 is aligned with the first locking hole 203.
