A kind of well cover for sewer, comprise: cover body, the tumbler that can make cover body rotate, anti-drop net, interior ring seat and outer ring seat, described outer ring seat is fixed on the matrix of ground by expansion bolt, described interior ring seat is set in outer ring seat and by screw and outer ring seat Joint, described interior ring seat medial surface centre position place is outwards recessed to form annular groove, described interior ring seat medial surface bottom position place is processed with one section of profile of tooth, the end face of described interior ring seat offers at least one locking bolt docking port downwards, described locking bolt docking port is connected with annular groove, described anti-drop net is held in interior ring seat, described cover body is set in interior ring seat and is positioned at anti-drop net top, described cover body offers a longitudinal open keyhole near its edge, described open keyhole be positioned at profile of tooth directly over, on described cover body, there is the locking bolt with quantity such as locking bolt docking ports, described locking bolt is by body, block rubber and lock pin composition, described body and cover body Joint, described block rubber and lock pin are arranged in body, the tail end of described lock pin contacts with block rubber, its head end and locking bolt docking port match and are arranged in annular groove, described tumbler is made up of cross bar, vertical pole and gear, and described gear is fixed in vertical pole bottom, and described vertical pole and open keyhole match, and described gear and profile of tooth match.
On technique scheme basis, on the vertical pole of described tumbler, there is the annular protrusion of a radial direction, annular protrusion bottom surface to the distance of gear teeth tips equates with cover body end face to the distance of the tooth top of profile of tooth.
On technique scheme basis, described anti-drop net is made up of the spoke of several concentric annular rings and some radial direction distributions, and described spoke connects each concentric annular ring, and outermost annular ring has one and lacks limit, and described scarce limit and profile of tooth are in the same side.
On technique scheme basis, described anti-drop net is bolted in interior ring seat.
On technique scheme basis, the bottom surface of described cover body forms some supporting legs.
On technique scheme basis, described supporting leg is annular.
On technique scheme basis, described locking bolt docking port and locking bolt are three, and between adjacent locking bolt docking port, angle is 120 degree, and between adjacent locking bolt, angle is 120 degree.
The utlity model has following advantage: easy to use, anti-drop net can avoid cover body pedestrian after removing to fall, cover body runs into extreme weather and is also difficult for being backed down after engaging with interior ring seat, installation and transportation are convenient, can prevent displacement, upset, due to interior ring seat and outer ring seat separable, in use the conventionally interior outer ring seat of ring seat is first damaged, now only need pull down the interior ring seat that interior ring seat more renews, dismantle without external ring seat, thereby can not destroy ground.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figures 1 to 7, a kind of well cover for sewer of the present embodiment, comprise: cover body 2, the tumbler 1 that can make cover body 2 rotate, anti-drop net 3, interior ring seat 4 and outer ring seat 5, described outer ring seat 5 is fixed on ground matrix 6 by expansion bolt 50, described interior ring seat 4 is set in outer ring seat 5 and by screw 40 and outer ring seat 5 Joints, described interior ring seat 4 medial surface centre position places are outwards recessed to form annular groove 41, described interior ring seat 4 medial surface bottom position places are processed with one section of profile of tooth 42, the end face of described interior ring seat 4 offers at least one locking bolt docking port 43 downwards, described locking bolt docking port 43 is connected with annular groove 41, described anti-drop net 3 is held in interior ring seat 4, described cover body 2 is set in interior ring seat 4 and is positioned at anti-drop net 3 tops, described cover body 2 offers a longitudinal open keyhole 20 near its edge, described open keyhole 20 be positioned at profile of tooth 42 directly over, on described cover body 2, there is the locking bolt 21 with quantity such as locking bolt docking ports 43, described locking bolt 21 is by body 22, block rubber 23 and lock pin 24 form, described body 22 and cover body 2 Joints, described block rubber 23 and lock pin 24 are arranged in body 22, the tail end of described lock pin 24 contacts with block rubber 23, its head end and locking bolt docking port 43 match and are arranged in annular groove 41, described tumbler 1 is made up of cross bar 10, vertical pole 11 and gear 13, and described gear 13 is fixed in vertical pole 11 bottoms, and described vertical pole 11 matches with open keyhole 20, and described gear 13 matches with profile of tooth 42.
