Detailed Description
The invention is further described with reference to the following figures and embodiments.
First embodiment
Please refer to fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5 in combination, wherein fig. 1 is a schematic structural diagram of a municipal manhole cover capable of draining water in time in a sudden heavy rain weather according to a first embodiment of the present invention; FIG. 2 is a schematic view of the opened grid plate of FIG. 1; FIG. 3 is a schematic view of the drain structure shown in FIG. 2 after opening; FIG. 4 is an enlarged view of portion A of FIG. 3; fig. 5 is a front sectional view of the frame shown in fig. 1. But municipal well lid of proruption heavy rain weather drainage in time includes: a frame 1;
the grid plate 2 is mounted on the top of the frame 1 through bolts;
the water draining structure 4 comprises a first groove 41, a first water draining hole 42 is formed in the first groove 41, connecting blocks 43 are fixedly connected to two sides of the inner wall of the first water draining hole 42, a fixing sleeve 44 is fixedly connected between two opposite sides of the two connecting blocks 43, a connecting rod 45 is sleeved in the fixing sleeve 44, a floating plate 46 is fixedly connected to the top end of the connecting rod 45, and an anti-falling block 47 is fixedly connected to the bottom end of the connecting rod 45;
the two second drain holes 5 are respectively formed in two sides of the frame 1, a second groove 6 is formed in the top of the inner wall of each second drain hole 5, a moving block 7 is connected between two sides of the inner wall of each second groove 6 in a sliding mode, an extension spring 8 is arranged between the top of each moving block 7 and the top of the inner wall of each second groove 6, a fixed rod 9 is fixedly connected to the bottom of each moving block 7, a connecting piece 10 is fixedly connected to the bottom end of each fixed rod 9, and the other side of each connecting piece 10 is fixed to the corresponding sliding plate 3.
The diameter of the floating plate 46 is smaller than that of the first groove 41, and a gap is reserved between the floating plate 46 and the first groove 41.
Rainwater can be conveniently introduced into the inside of the first groove 41 through the reserved gap, thereby facilitating the floating of the floating plate 46.
The front and the back of the frame 1 are both fixedly connected with mounting blocks 11, the mounting blocks 11 are provided with threaded holes, the height of the mounting blocks 11 is 3/4 of the height of the frame 1, and the height of the second drain holes 5 is 1/2 of the height of the frame 1.
