[0001] The utility model relates to the technical field of drainage equipment, in particular to a water supply and drainage safety manhole cover. Background Art
[0002] Manhole covers are mostly used in green belts, sidewalks, motorway, docks, alleys and other places. Most of them are mainly used to cover deep wells on the road to prevent people or objects from falling and ensure the normal driving of vehicles on the road. General drainage manhole covers are mainly used to drain water and avoid water accumulation on the road, which plays a significant role in the urban drainage system.
[0003] Manhole covers are essential facilities in municipal engineering construction. They can drain water from the road into the sewer. When water is discharged through the manhole covers, there is debris in the water. The debris is discharged from the holes on the manhole covers along with the water. Part of the debris enters the holes, and part is located at the upper end of the manhole cover. The debris in the hole occupies the space area of the drainage hole, thereby reducing the discharge rate of the water. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Example 1: Reference Figure 1-4 A water supply and drainage safety manhole cover, comprising a manhole cover body 1 and a fixing seat 2, the manhole cover body 1 and the fixing seat 2 cooperate with each other, an anti-corrosion layer is sprayed on the manhole cover body 1, a drainage hole 3 is opened on the manhole cover body 1, a pushing mechanism 4 for accelerating the passage of debris is connected to the drainage hole 3, and a sand-proof frame 5 is fixedly connected to the upper end of the manhole cover body 1;
[0023] The pushing mechanism 4 includes a rotating shaft 41. A first groove 42 is opened at the bottom end of the manhole cover body 1. The first groove 42 is connected to the drainage hole 3. The rotating shaft 41 is rotatably connected to the first groove 42. A fixing sleeve 43 is fixedly connected to the rotating shaft 41. A plurality of blades 44 are connected to the fixing sleeve 43 at equal intervals along the axial direction. The fixing sleeve 43 and the blades 44 are an integrated structure, and the blades 44 can extend into the drainage hole 3.
[0024] Working process: install the fixing seat 2 on the sewer, place the manhole cover body 1 on the fixing seat 2, cover the fixing seat 2, the upper end of the manhole cover body 1 is flush with the upper end of the fixing seat 2, the anti-sand frame 5 is higher than the upper end of the fixing seat 2, and the anti-sand frame 5 blocks part of the sand in the water when the water flows to the manhole cover body 1. The water flowing through the upper end of the anti-sand frame 5 falls on the upper end of the manhole cover body 1, and the upper end of the manhole cover body 1 is released from the drainage hole 3. The released water impacts the blade 44 under its own gravity. After being impacted by the water, the blade 44 drives the fixing sleeve 43 to rotate around the rotating shaft 41. After the blade 44 rotates, it pushes the debris in the drainage hole 3 downward. The debris slides downward after being pushed downward by the blade 44. After moving downward, the debris is separated from the drainage hole 3 and will not occupy the spatial area of the drainage hole 3, so that the drainage hole 3 is in a smooth state, thereby improving the water discharge speed.
[0025] Embodiment 2: In embodiment 1, after the manhole cover body 1 is placed on the fixing seat 2, when a vehicle passes over the manhole cover body 1, the manhole cover body 1 slides, and relative sliding occurs between the manhole cover body 1 and the fixing seat 2, thereby causing relative friction between the contact surfaces of the manhole cover body 1 and the fixing seat 2, thereby reducing the anti-corrosion performance of the contact surfaces of the manhole cover body 1 and the fixing seat 2. Figure 5As another preferred embodiment of the utility model, the difference from embodiment 1 is that an anti-slip mechanism 6 is connected to the manhole cover body 1, and the anti-slip mechanism 6 includes a second groove 61. The second groove 61 is provided on the outer wall of the manhole cover body 1, and a positioning rod 62 is slidably connected to the second groove 61. A spring 63 is fixedly connected in the second groove 61, and one end of the spring 63 is fixedly connected to the positioning rod 62. A positioning hole is provided on the fixing seat 2, and the positioning hole cooperates with the positioning rod 62. The bottom end of the manhole cover body 1 is fixedly connected to the limiting rod 64 on both sides, and the upper end of the fixing seat 2 is provided with connection holes 65 on both sides. The two limiting rods 64 cooperate with different connecting holes 65. When the manhole cover body 1 is installed, the limiting rods 64 are inserted into the connecting holes 65 so that the manhole cover body 1 is aligned with the fixing seat 2. The manhole cover body 1 is moved downward, and the positioning rod 62 is pressed. The positioning rod 62 squeezes the spring 63 and then retracts into the second groove 61. After the manhole cover body 1 is placed in the fixing seat 2, the spring 63 pushes the positioning rod 62 to extend, and the positioning rod 62 passes through the positioning hole to limit the manhole cover body 1, so that relative sliding does not occur between the manhole cover body 1 and the fixing seat 2, thereby not reducing the anti-corrosion performance of the contact surface between the manhole cover body 1 and the fixing seat 2.
[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
