[0002] The sewage network is a network of pipes and pipelines that collect sewage from a city or a region and transport it to a sewage treatment plant for treatment. The network structure formed by these pipes and pipelines is called the sewage network. It includes sewage collection pipes, sewage transmission pipes, sewage treatment plant inlet pipes, and related pumping stations, regulating tanks, sedimentation tanks and other facilities. The function of the sewage network is to effectively transport domestic, industrial and rainwater sewage from cities, industrial areas or other areas to sewage treatment plants for treatment, so as to achieve the requirements of purification, reuse or discharge.

[0027] The filter assembly 200 includes a cover plate 210 and a filter frame 220. The filter frame 220 is mounted inside the upper end of the tube body 100. The cover plate 210 is movably mounted on the upper side of the filter frame 220.

[0028] The anti-overflow assembly 300 includes a fixed seat 310, a guide member 320 and a movable plate 330. A guide member 320 is fixed to the left and right sides of the upper surface of the fixed seat 310, and a movable plate 330 is movably mounted on the lower end of the fixed seat 310 through the guide member 320.

[0029] See also Figure 1 An inner cavity 110 is provided inside the tube body 100 , and the inner edge of the upper end of the tube body 100 is recessed downward to form a slot 120 . The inner diameter of the slot 120 is larger than the inner diameter of the inner cavity 110 , and the slot 120 is connected to the upper end of the inner cavity 110 .

[0030] The diameter of the upper end of the filter frame 220 matches the inner diameter of the slot 120. The upper end of the filter frame 220 is mounted on the upper end of the tube body 100 through the slot 120, and the lower end of the filter frame 220 is suspended in the inner cavity 110. The setting of the filter frame 220 can filter the sewage entering the tube body 100 to prevent the sewage from being mixed with garbage and blocking the anti-overflow component 300.

[0031] The lower end of the filter frame 220 does not contact the inner wall of the inner cavity 110 , and a plurality of filter holes 222 distributed in an annular shape are formed on the side wall of the lower end of the filter frame 220 . A filter screen 223 is disposed at the lower end of the filter frame 220 .

The upper end of the filter frame 220 is movably mounted with the cover plate 210 through the second card slot 221. The upper surface of the cover plate 210 penetrates downward to form a plurality of evenly distributed leakage holes 211.

[0033] As the first embodiment of the present utility model, in actual use, external sewage enters the filter frame 220 through the leakage hole 211 on the upper side of the cover plate 210. Since the side wall of the filter frame 220 is provided with multiple filter holes 222, and the bottom is provided with a filter screen 223 (here the aperture size of the filter screen 223 can be set according to actual needs, the filter screen 223 can be a metal mesh, or a metal perforated plate, or a filter screen 223 structure composed of a horizontal and vertical steel bar mesh and a nylon mesh, which is not limited to a certain structure and can be selected according to actual use needs), the sewage entering the filter screen 223 will be filtered through the filter holes 222 and the filter screen 223, and then will reach the anti-overflow component 300, which can effectively prevent the sewage from carrying impurities and garbage to the upper side of the anti-overflow component 300, thereby blocking the main through hole 311 and the secondary through hole 312, making the entire anti-overflow component 300 invalid, effectively protecting the anti-overflow component 300 and improving the service life of the anti-overflow component 300.

[0034] See also Figures 1 to 4 The fixing seat 310 is fixedly connected to the inner wall of the pipe body 100, and a main through hole 311 is formed by penetrating downwardly in the middle of the upper surface of the fixing seat 310. A plurality of secondary through holes 312 distributed in a ring structure are opened downwardly at the edge of the upper surface of the fixing seat 310. The middle of the lower surface of the fixing seat 310 is recessed upward to form a card groove three 313. The card groove three 313 is connected to the main through hole 311 and the secondary through hole 312. The setting of the anti-overflow component 300 can effectively prevent the sewage inside the pipe body 100 from flowing back.

[0035] The movable plate 330 includes a circular plate 331 and a movable suspension rod 332. The outer diameter of the circular plate 331 matches the inner diameter of the slot 313. A movable suspension rod 332 is welded to the left and right sides of the upper surface of the circular plate 331. The upper ends of the two movable suspension rods 332 penetrate the fixed seat 310 and are slidably connected thereto. The guide member 320 includes a protective cover 321 and a spring 322. The protective cover 321 is fixed to the left and right sides of the upper surface of the fixed seat 310. A spring 322 is installed inside each protective cover 321.

[0036] The upper ends of the two movable suspension rods 332 are movably installed in the protective cover 321 through springs 322. Limiting plates are provided on the upper ends of the two movable suspension rods 332. The springs 322 are sleeved on the upper ends of the movable suspension rods 332, and the springs 322 are placed between the limiting plates and the upper surface of the fixed seat 310. The limiting plates are slidably connected to the inner wall of the protective cover 321.

[0037] As a second embodiment of the present utility model, based on the above-mentioned first embodiment, in actual use, when the filtered sewage reaches the upper side of the fixed seat 310, pressure is formed on the movable plate 330 installed on the lower side of the fixed seat 310 through the main through hole 311 and the secondary through hole 312. When this pressure is greater than the supporting force provided by the two springs 322, the movable suspension rod 332 gradually moves downward in the protective cover 321, thereby causing the spring 322 to be gradually compressed. At the same time, the circular plate 331 gradually moves downward and leaves the card slot three 313. When the circular plate 331 completely leaves the card slot three 313, the circular plate 331 and the fixed There is a gap between the fixed seat 310, and the sewage located on the upper side of the fixed seat 310 can enter the slot three 313 through the main through hole 311 and the secondary through hole 312, and then enter the lower end of the inner cavity 110 of the pipe body 100 through the gap between the circular plate 331 and the fixed seat 310, and then flow to the sewage pipe network connected to the pipe body 100. In summer, when there is more rain and the sewage in the sewage pipe network flows back from the lower side of the pipe body 100, the movable plate 330 is pressed upward and tightly stuck in the slot three 313, and the circular plate 331 and the slot three 313 on the lower side of the fixed seat 310 form a seal, thereby preventing the sewage from flowing back and overflowing.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
