DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 A drainage manhole cover for water supply and drainage, comprising a manhole cover 1, the lower end of the manhole cover 1 is connected to a manhole body 2, a deodorizing frame 3 is installed at the lower end of the inner wall of the manhole cover 1, a fixing plate 4 is installed at the lower end of the deodorizing frame 3, a connecting block 5 is installed at the lower end of the fixing plate 4, a connecting rod 6 is movably connected to the lower end of the connecting block 5, a plurality of supporting rods 7 are fixedly installed at the lower end of the connecting rod 6, a ring 8 is connected to the lower end of the supporting rod 7, a filter screen 9 is connected to the lower end of the ring 8, and a slide groove 18 is opened on the inner wall of the manhole body 2;

[0022] Furthermore, activated carbon can be placed in the deodorizing frame 3 to absorb odors and avoid air pollution. The connecting block 5 is hinged to the connecting rod 6, so that the connecting rod 6 can be driven when the manhole cover 1 is lifted, thereby lifting the filter screen 9 mounted on the ring 8 for easy replacement and cleaning.

[0023] Furthermore, an annular groove 10 and a prying opening 11 are provided on the upper surface of the manhole cover 1, and a water inlet groove 12 is provided at the lower end of the manhole cover 1. A baffle 13 is movably connected inside the water inlet groove 12, and a hinge 14 is installed on the upper end of the inner wall of the baffle 13, and the other half of the hinge 14 is installed on the inner wall of the manhole cover 1; the upper end of the inner wall of the baffle 13 is fixedly connected to the inner wall of the manhole cover 1 through a hinge, so that the baffle can be movably flipped over to facilitate drainage.

[0024] Furthermore, a plurality of telescopic rods 15 are connected to the outside of the fixed plate 4, and a spring 16 is installed in the fixed end of the telescopic rod 15. The telescopic end of the telescopic rod 15 is hinged to the lower end of the inner wall of the baffle 13; when the force of the water flow is greater than the spring force, the baffle 13 is flushed open and begins to drain water. As the water flow becomes smaller and less than the spring force, the telescopic end is pushed back to the baffle 13 to restore, thereby reducing odor escape.

[0025] Furthermore, a plurality of blocks 17 are installed on the outside of the circular ring 8, and the blocks 17 are slidably installed in the slide groove 18; when the manhole cover 1 is lifted, the pulling force is transmitted to the connecting rod 6 and the support rod 7, the circular ring 8 is pulled upward, and the blocks 17 slide in the slide groove 18 to prevent the circular ring from shaking.

[0026] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0027] Embodiment: First, when the rainwater is small, the annular groove 10 on the surface of the manhole cover 1 can be used to drain the water. When the rainwater is getting heavier, the water flow will wrap the entire manhole cover. When the force of the water flow is greater than the spring force, the rainwater will push the baffle 13 movably connected in the water inlet groove 12 and flow into the manhole body. At this time, the spring 16 in the fixed end of the telescopic rod 15 is in a compressed state. When the water flow decreases and the impact force is less than the spring force, the spring 16 recovers, so that the telescopic end of the telescopic rod 16 pushes back the baffle 13 to reset in the water inlet groove 12 to complete the closure. The debris washed in by the rainwater is intercepted by the filter net. When it needs to be cleaned at some time, the staff uses the prying mouth 11 to open the manhole cover 1. When the manhole cover 1 rises, it drives the connecting rod 6 hinged under the fixing plate 4, and the bottom end of the connecting rod 6 is installed with the supporting rod 7. Finally, the lifting of the manhole cover 1 will drive the ring 8 to rise to the well mouth. Because the filter screen 9 is mounted on the ring 8, the staff can clean the solid debris trapped in the filter screen and replace it; the block 17 on the outside of the ring 8 slides up and down in the slide groove 18, which not only stabilizes the ring when it moves up and down, but also connects the manhole cover 1 and the well body 2 into a whole, reducing the risk of the manhole cover 1 being stolen. At the same time, because of such a design, the force required to open the manhole cover 1 is very large, which avoids the manhole cover 1 from being pried open at will, thereby improving safety.
