It can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. Manhole covers can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc. Generally, they are divided into circular and square shapes. In the municipal administration in urban areas, circular manhole covers are generally used because circular manhole covers are not easily tilted and can better protect the safety of pedestrians and vehicles. In rural areas and for cable wells, square manhole covers are generally used to better prevent the entry of liquids such as rainwater.

[0003] Due to the need for cleaning the sewer environment, the existing manhole covers only have small water leakage holes to prevent road garbage from falling into the sewer. However, when encountering rainy weather, the small holes design makes it impossible to quickly drain the ponding on the road surface, thus covering the road surface conditions. In the case of excessive ponding, the manhole cover is usually opened for emergency drainage. However, during the drainage process, sundries will enter the drainage pipeline along with the water flow. Over time, this will cause the drainage pipeline to be blocked by sundries, seriously affecting the drainage system. An anti-ponding manhole cover for municipal roads. Content of the Utility Model

However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1

[0024] As Figures 1 - 5 shown, the present invention provides a technical solution: a municipal road anti-ponding manhole cover, including a base 1 and a manhole cover 2. A drainage hole 201 is opened at the top of the manhole cover 2, a filter screen 21 is fixedly installed inside the drainage hole 201, a limit groove 202 is opened at the top of the manhole cover 2, a through hole 203 is opened at the bottom of the manhole cover 2, a load-bearing cover 3 is movably installed inside the limit groove 202, a turning handle 4 is movably installed at the top of the base 1, a stop block 5 is movably installed inside the through hole 203, a groove 301 is opened at the top of the load-bearing cover 3, a pull rod 31 is fixedly connected to the bottom end of the inner wall of the groove 301, and the shape of the load-bearing cover 31 fits the shape of the limit groove 202.

[0025] In this embodiment, the manhole cover 2 is installed on the top of the base 1, and the load-bearing cover 3 is placed inside the limit groove 202 to cover the stop block 5. The load-bearing cover 3 is limited by the limit groove 202 and cannot move downward, preventing pedestrians from stepping on the stop block 5 and causing it to fall, improving the safety of the manhole cover 2. When there is ponding on the road, the drainage hole 201 opened at the top of the manhole cover 2 can drain a small amount of ponding, and the filter screen 21 installed inside the drainage hole 201 can filter the debris in the ponding.

[0026] Embodiment 2

[0027] As Figures 1 - 5As shown, the shape of the stop block 5 fits the shape of the through hole 203. The diameter length of the limit groove 202 is greater than the diameter length of the through hole 203. The bottom of the limit groove 202 communicates with the top of the through hole 203. A positioning rod 22 is fixedly connected to the bottom of the manhole cover 2. A limit block 221 is fixedly connected to the bottom of the positioning rod 22. A filter cylinder 23 is fixedly connected to the bottom of the manhole cover 2. A fixing plate 51 is fixedly connected to the bottom of the stop block 5. The fixing plate 51 is slidably mounted on the surface of the positioning rod 22. The stop block 5 is mounted at the bottom of the limit groove 202. The stop block 5 movably penetrates through the inside of the filter cylinder 23. A screw rod 41 is fixedly connected to the bottom of the turning handle 4. The surface of the screw rod 41 is threadedly connected to the inner wall of the fixing plate 51.

[0028] In this embodiment, when too much rainwater accumulates on the manhole cover 2, the pull rod 31 is lifted upward to take out the load-bearing cover 3 from the inside of the limit groove 202. At this time, the limit groove 202 is in a flowing state. The turning handle 4 is rotated to drive the screw rod 41 to rotate. The rotation of the screw rod 41 causes the fixing plate 51 to move downward on its surface, and the side surface of the fixing plate 51 slides on the surface of the positioning rod 22. When the fixing plate 51 slides to the bottom of the positioning rod 22, the top end of the stop block 5 is located inside the filter cylinder 23. The accumulated water flows into the through hole 203 and is discharged through the filter cylinder 23, and the sundries mixed in the accumulated water are filtered inside the filter cylinder 23 to prevent too many sundries from entering the pipeline and causing blockage. The stop block 5 covers the bottom of the filter cylinder 23 to prevent the sundries from flowing out. When the discharge of the accumulated water is completed, the turning handle 4 is reversed to raise the stop block 5, and at the same time, the stop block 5 pushes the sundries inside the filter cylinder 23 upward, facilitating the cleaning of the sundries.

[0029] The working principle of this embodiment: When there is accumulated water on the road, the drain hole 201 opened at the top of the manhole cover 2 can discharge a small amount of accumulated water, and the filter screen 21 installed inside the drain hole 201 can filter the sundries in the accumulated water. When too much rainwater accumulates on the manhole cover 2, the pull rod 31 is lifted upward to take out the load-bearing cover 3 from the inside of the limit groove 202. The turning handle 4 is rotated to drive the screw rod 41 to rotate. The rotation of the screw rod 41 causes the fixing plate 51 to move downward on its surface. The accumulated water flows into the through hole 203 and is discharged through the filter cylinder 23, and the sundries mixed in the accumulated water are filtered inside the filter cylinder 23. When the discharge of the accumulated water is completed, the turning handle 4 is reversed to raise the stop block 5, and at the same time, the stop block 5 pushes the sundries inside the filter cylinder 23 upward, facilitating the cleaning of the sundries.

[0030] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
