Description

Prefabricated manhole cover Technical Field The application relates to the technical field of well covers, in particular to a prefabricated inspection well cover. Background In the infrastructure of present city, the road drainage is one of the most important items, and good drainage can effectively guarantee the safety and the unobstructed of road traffic, and normally ponding is in the wash water course through the wash port at well lid top, and the drainage well is the conventional means of drainage, can set up the well lid in the opening part of drainage well generally, carries out protection city. Drainage inspection well lid is opened at ponding point scene to drainage management personnel, lets the rainwater directly drain from the inspection well head for drainage speed. The related art can refer to the chinese patent with publication number CN205975696U to disclose a butt-clamp openable anti-theft drainage manhole cover, which comprises two semicircular manhole cover units, the straight sides of the two semicircular manhole cover units are rotatably fixed on a connecting shaft, and two ends of the connecting shaft are fixed on the rim of the drainage manhole. The well cover has the anti-theft function, can be opened quickly when needed, can drain accumulated water on the road surface quickly, can be operated by a single person, and provides great convenience for water supply and drainage management personnel. Aiming at the related technology, the manhole cover is exposed after being opened, so that the sight is unclear in rainy days or at night, and the safety problem that personnel step on the manhole cover to fall down can occur. Disclosure of utility model In order to improve safety, the application provides a prefabricated manhole cover. The application provides a prefabricated manhole cover, which adopts the following technical scheme: The utility model provides a prefabricated manhole cover, includes upper cover and lower cover, the water drainage tank has been seted up to the upper cover, and the outlet of a plurality of and water drainage tank intercommunication has been seted up to the lower cover, is equipped with flip in the water drainage tank, and flip rotates along the axis that is close to the horizontal direction of flip side and upper cover to be connected, flip up end and upper cover up end parallel and level, terminal surface and lower cover butt under the flip, and the terminal surface is fluted under the flip, and the recess rotation is connected with branch, and the draw-in groove with the branch adaptation is covered down, and flip and the rotation direction of branch are the same, upper cover and lower cover integrated into one piece. Through adopting above-mentioned technical scheme, when flip was in closed position, branch was located flip's recess, flip up end and upper cover up end parallel and level. When the drainage is needed, the supporting rod rotates out of the groove through rotating the flip, the flip is completely opened, one end, away from the flip, of the supporting rod is clamped into the clamping groove, and the functions of supporting and fixing the flip are achieved. At this moment, rivers flow into the drainage well of drainage tank and the outlet of lower cover of upper cover, and the lower cover leaves partial structure in drainage tank department, when making the pedestrian step on, the lower cover can play the supporting role, makes the pedestrian can not step on the sky and fall into in the well, and flip that overturns simultaneously is fixed the back, flip be higher than the surface of water in vertical direction, makes the pedestrian can see, also can play the warning effect, has improved the security. Optionally, the flip is kept away from one side of the axis of rotation of self and upper cover and is the inclined plane, the locking groove has been seted up on the inclined plane, the spout has been seted up to the lateral wall that the water drainage tank is close to the locking groove, the horizontal distance from the top down between lateral wall that the spout has been seted up to the water drainage tank and the inclined plane increases gradually, be equipped with latch segment and elastic component in the spout, elastic component both ends respectively with latch segment and spout wall fixed connection, under the elastic component natural state, the one end that the latch segment is close to the elastic component is located the spout, the one end that the latch segment kept away from the elastic component is located the locking groove, the latch segment is along direction and upper cover sliding connection of perpendicular to flip axis of rotation, be equipped with the unlocking means who is used for making the latch segment break away from the locking groove in the locking groove. Through adopting above-mentioned technical scheme, the design on inclined plane makes flip can extrude the latch segment to remove in the spout when closing, when
