Technical Field

[0001] This utility model relates to the field of municipal water supply and drainage technology, and in particular to a municipal water supply and drainage device. Background Technology

[0002] Municipal water supply and drainage systems refer to water supply and drainage systems, which are important components of urban infrastructure. They are used to supply clean drinking water to urban residents and remove sewage. These systems typically include equipment and facilities such as water supply pipelines, sewage pipelines, water pumps, water towers, drainage pipes, and sewage treatment facilities.

[0003] Currently, some municipal water supply and drainage devices on the market are prone to clogging by fallen leaves, mud, and garbage after prolonged use. During rainy days, rainwater cannot quickly infiltrate and drain, resulting in water accumulation on the road. At the same time, the internal filter screen of the device is usually an integral fixed structure, and disassembly and cleaning require excavation of the road surface, which is time-consuming, labor-intensive, and costly. In order to address this technical problem, this application proposes a municipal water supply and drainage device. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-3 An embodiment of this utility model provides a municipal water supply and drainage device, including an outer sleeve 1, a well ring frame 2 fixedly connected to the outer wall of the outer sleeve 1, a limit frame 5 fixedly connected to the inner wall of the top side of the outer sleeve 1, a well cover 3 provided on the top side of the limit frame 5, two drain outlets 4 opened on the outer wall of the well cover 3, a sealing gasket 20 fixedly connected to the bottom side of the well cover 3, the inner wall of the top side of the outer sleeve 1 connected to the well cover 3 through a locking component, an inner sleeve 10 provided on the bottom side of the limit frame 5, a support frame 11 provided on the bottom side of the inner sleeve 10, and a filter component provided on the top side of the support frame 11.

[0018] Specifically, when installing the device, the soil in the installation area is first excavated, then compacted, and leveled. A formwork is then used to support the structure, and the outer sleeve 1 is placed in the formwork. Concrete is then poured in, and the concrete solidifies to fix the well ring frame 2 of the outer sleeve 1. The filter assembly is then placed into the inner sleeve 10, and the locking assembly is activated by a special key. Finally, the manhole cover 3 is placed on top. Normally, when leaves or stones enter the device, they will be collected by the filter assembly to prevent them from entering the pipe. At the same time, in the event of heavy rain, rainwater will be discharged from the flood discharge point of the filter assembly to prevent water accumulation in the area.

[0019] Reference Figures 4-6The locking assembly includes an unlocking block 13 rotatably connected to the inner wall of the top side of the outer sleeve 1. A connecting rod 16 is fixedly connected to the bottom side of the unlocking block 13, and a gear 17 is fixedly connected to the outer wall of the bottom side of the connecting rod 16. A locking block 12 is provided at the end of the connecting rod 16. A sliding groove 19 is provided on the top of the locking block 12, and a rack 18 is fixedly connected to the outer wall of the sliding groove 19. One end of the locking block 12 is connected to the manhole cover 3, and a spring 15 is provided at the other end of the locking block 12. The outer wall of the locking block 12 is slidably connected to the outer sleeve 1, and the outer wall of the gear 17 is meshed with the rack 18. The top of the unlocking block 13... An unlocking hole 14 is provided on the outer wall of the manhole cover. One end of the spring 15 is connected to the outer sleeve 1, and the other end of the spring 15 is connected to the locking block 12. When the manhole cover 3 needs to be installed, the unlocking block 13 is rotated by inserting the customized matching key into the unlocking hole 14. The unlocking block 13 drives the connecting rod 16 to rotate, which in turn drives the gear 17 to rotate. The gear 17 drives the rack 18 to move, thereby causing the locking block 12 to retract in the outer sleeve 1. After installation, the key is released, and the spring 15 will reset the locking block 12. The locking block 12 will be inserted into the manhole cover 3, thereby fixing the manhole cover 3.

[0020] Reference Figures 2-4 The filter assembly includes a filter screen 7 located on the top side of the support frame 11. The filter screen 7 has multiple holes 8 in the middle and multiple flood discharge outlets 9 on the outer walls around it. The top of the filter screen 7 is an arc-shaped structure. Leaves and pebbles will fall into the bottom of the arc after entering the device. Rainwater that is normally accumulated will fall into the sewer pipe through the holes 8. When there is a rainstorm, the rainwater accumulates in the arc and then flows into the pipe through the multiple flood discharge outlets 9 around the filter screen 7.

[0021] The top of the filter screen 7 is connected to the inner sleeve 10. The inner sleeve 10 can prevent leaves and stones from falling into the drain pipe from all sides after entering the device. The bottom side of the filter screen 7 is connected to the support frame 11, which supports the filter screen 7. The top side of the limiting frame 5 has a sealing groove 6. The outer wall of the sealing gasket 20 is connected to the sealing groove 6. The tightly fitting sealing gasket 20 and sealing groove 6 can prevent the manhole cover 3 from tipping over. The sealing gasket 20 is made of rubber, which can prevent vibration and abnormal noise.

[0022] Working principle: After the outer sleeve 1 is installed, the filter screen 7 is placed into the inner sleeve 10. The unlocking block 13 is rotated by inserting the customized matching key into the unlocking hole 14. The unlocking block 13 drives the connecting rod 16 to rotate, which in turn drives the gear 17 to rotate. The gear 17 drives the rack 18 to move, thereby causing the locking block 12 to retract in the outer sleeve 1. Then the manhole cover 3 is placed. The sealing gasket 20 on the bottom side of the manhole cover 3 will be engaged in the sealing groove 6 of the limit frame 5. The tight fit between the sealing gasket 20 and the sealing groove 6 can prevent the manhole cover 3 from tipping over. The sealing gasket 20 is made of rubber, which can prevent vibration and abnormal noise. After installation, release the key, and spring 15 will reset locking block 12. Locking block 12 will then insert into manhole cover 3, thus securing manhole cover 3. The top of filter screen 7 has an arc-shaped structure. Normally, when leaves or stones enter the device, they will be collected by filter screen 7 to prevent them from entering the pipe. When there is heavy rain, rainwater enters inner sleeve 10 through drain 4. Then, the rainwater accumulates in the arc of filter screen 7 and is discharged into the pipe through multiple flood outlets 9 around filter screen 7. After a period of use, open manhole cover 3, hook the flood outlets 9 with iron hooks to remove filter screen 7, then pour the collected leaves into the trash can, and then reinstall it.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
