Description

Technical Field

[0001] The invention relates to the technical field of urban road drain outlet filtration, and specifically proposes a sponge urban road drain outlet filtration device. Background Art

[0002] Sponge city is a new concept of urban stormwater management. It focuses on building a "sponge body" with natural storage, natural infiltration and natural purification functions. It aims to improve the efficiency of the urban drainage system and reduce the occurrence of urban waterlogging. At the same time, it can replenish groundwater and improve the urban ecological environment.

[0003] At present, open stormwater inlets are widely used in urban road pipe networks, and surface runoff is directly discharged into the drainage system and flows into the river through the stormwater inlets. With the rapid development of cities, the disadvantages of open stormwater inlets have gradually emerged in the operation of road pipe networks, such as the inability to intercept large pieces of solid waste, serious garbage blockage in stormwater inlets, accumulation of solid waste in pipes, reduced flow capacity, difficulty in drainage and easy waterlogging; serious non-point source pollution, difficult maintenance and troublesome cleaning; the inability to separate rainwater and sewage, causing pollution of the entire water system, etc.

[0004] Therefore, an efficient installation and construction technology for interception, drainage and filtration multifunctional modular rainwater inlets based on sponge cities has been developed. The traditional open rainwater inlets are improved into interception, drainage and filtration multifunctional modular rainwater inlets. The interception, drainage and filtration multifunctional modular rainwater inlets are targeted at the pain points of urban drainage. The drainage outlet filtration device (such as a concrete shell, a processor liner, two special filter cottons, a spoiler, a sewage interception basket and a panel) is used. Figure 2 ) to achieve the purpose of solid waste interception, hazardous waste filtering, and clean rainwater discharge. The resin concrete shell has a pressure bearing capacity of D400, and water-passing louvers are arranged on both sides of the processor inner tank; when it rains lightly, the louvers are closed, and rainwater passes through the sewage interception hanging basket to filter solid waste. The rainwater flows downward and is filtered and adsorbed again by a special filter element to remove pollutants in the initial rainwater; when it rains heavily, the rainwater overflows and opens the water-pass louvers for rapid discharge; on sunny days, the louvers are closed to prevent mosquitoes and odor, effectively reducing initial rainwater pollution.

[0005] However, the concrete shell, processor liner, sewage interception basket and panel in the drain outlet filtering device currently used are directly inserted and installed. During use, various components are easy to loosen, especially when subjected to water impact or external vibration, thereby reducing the impact strength of the drain outlet filtering device. In addition, the processor liner, sewage interception basket and panel are easily detached from the concrete shell under the impact of water flow and the buoyancy of water in heavy rain, posing a safety hazard to pedestrians and vehicles.

The side walls of the rotating rods 40 are installed with a driving locking group 32 for plugging with the drainage hole 230 and a locking and limiting group 41 for locking and limiting the plug plate 31. After the top of the rotating rod 40 slides through the processor liner 20 and the sewage interception basket 23, an integrated locking group 42 is set between the concrete shell 1.

[0046] During installation, the arc plug 30 is first driven by the plug plate 31 to be inserted into the arc slot 60, and then the processor liner 20, two special filter cottons 21, spoiler 22, sewage interception basket 23 and panel 24 are installed on the concrete shell 1 in sequence. At this time, the two ends of the plug plate 31 are respectively inserted into the drainage pipe 6 and the panel 24, so as to limit the processor liner 20, the sewage interception basket 23 and the panel 24, and then the integrated locking group 42 is used to drive the rotating rod 40 to rotate, so that the rotating rod 40 drives the locking limit group 41 to drive the locking group 32 to insert into the drainage hole 230 to limit the processor liner 20, further improving the stability of the installation of the processor liner 20.

[0048] The rotating rod 40 drives the locking limit group 41 to push the limit guide rod 322, and the limit guide rod 322 drives the card plug 323 to be inserted into the drainage hole 230, thereby locking the position of the processor liner 20, so that the upper and lower sides of the processor liner 20 are fixed, and then the upper end of the filter component 2 is fixed to the top of the concrete shell 1, and the lower end of the filter component 2 is plugged and locked on the drainage pipe 6, which improves the connection stability between the filter component 2 and the concrete shell 1, and avoids the processor liner 20 from shaking or moving under the impact force or buoyancy of water when the water flow is large, thereby shortening the service life of the drainage filter device.

[0049] See also Figure 8 The card plug 323 is convex, and the protrusion of the card plug 323 is a conical structure, so that the protrusion of the card plug 323 can be smoothly inserted into the drainage hole 230 to lock the position of the processor liner 20, thereby preventing the processor liner 20 from shaking under the impact of the water flow or moving under the buoyancy of the water.

The rotating rod 40 rotates to drive the locking plate 412 to enter the corresponding locking groove 410 or the arc groove 321. The locking plate 412 entering the arc groove 321 pushes the limiting guide rod 322 to drive the card plug 323 to move and insert into the drainage hole 230. The locking plate 412 opposite to the locking groove 410 is rotated and inserted into the locking groove 410 to lock the plug plate 31 to prevent the plug plate 31 from moving up and down.

[0051] See also Figure 3 , Figure 5 , Figure 6 , Figure 7 and Fig.10 The integrated locking group 42 includes a circular groove 420 opened at the top of the panel 24, a rectangular groove opened at the bottom of the circular groove 420, and a straight groove 421 extending from top to bottom at the bottom of the rectangular groove. The straight groove 421 extends downward through the processor liner 20 and the sewage interception basket 23. A straight bar 422 is installed on the top of the rotating rod 40, and a locking component for sealing the circular groove 420 and locking the straight bar 422 in position is installed in the circular groove 420.

Then, the straight bar 422 drives the rotating rod 40 to rotate, so that the rotating rod 40 drives the support plate 412 to rotate until the straight bar 422 rotates 90 degrees and presses against the upper end of the plug plate 31, thereby realizing a concrete shell 1 and the filter assembly 2. The whole is locked, and then the rectangular block 431 is driven by the blocking disk 430 to enter the rectangular groove. At this time, the I-shaped groove 432 is stuck on the I-shaped strip 422, so that the I-shaped strip 422 is locked under the cooperation of the I-shaped groove 432, the rectangular block 431 and the rectangular groove, to prevent the rotating rod 40 from rotating during use. Finally, the blocking disk 430 and the rectangular block 431 are driven to move downward through the threaded cooperation of the blocking disk 430 and the circular groove 420 until the rectangular block 431 is tightly against the bottom of the rectangular groove.

The arc portion of the arc guide bar 10 is used to divert sewage.

[0055] See also Figure 1-Figure 10When working, first insert the latch mechanism 3 into the concrete shell 1, and the lower end of the latch mechanism 3 is plugged into the outer wall of the top of the drainage pipe 6. Then, the processor liner 20, the special filter element, the spoiler 22, the sewage interception basket 23, and the panel 24 are installed in sequence. After that, the processor liner 20, the sewage interception basket 23, and the panel 24 are integrated and fixed on the concrete shell 1 with high strength through the latch mechanism 3 and the integrated locking mechanism 4. The processor liner 20 is locked in position in multiple directions, and the upper and lower sides of the processor liner 20 are fixed, thereby improving the connection stability between the filter component 2 and the concrete shell 1, avoiding the problem that the processor liner 20 shakes or moves under the impact force or buoyancy of water when the water flow is large, thereby shortening the service life of the drainage filter device. At the same time, the latch mechanism 3 and the integrated locking mechanism 4 have simple structures, which are convenient for installation and disassembly between the concrete shell 1 and the filter component 2.
