Description

Technical Field

[0001] This invention relates to the field of urban drainage technology, and in particular to a sewage interception device for sponge cities. Background Technology

[0002] With the deepening of sponge city construction, the refined management of urban drainage systems has become key to improving urban flood control capabilities and water environment quality. In the rainwater harvesting system of sponge cities, a collection basket is usually installed below the road surface grid (rainwater inlet) to intercept garbage, fallen leaves and silt in the rainwater runoff, preventing these impurities from entering the drainage network and causing blockages or pollution of downstream water bodies.

[0003] Existing sewage interception devices for sponge cities have several limitations in application: because the interception baskets are buried underground, maintenance personnel cannot quickly ascertain the state of sewage accumulation inside, leading to a contradiction between untimely cleaning causing interception failure and blind inspections resulting in wasted manpower; at the same time, traditional interception baskets mostly use fixed flow holes, which, under extreme rainstorms, can quickly clog the filter holes with a large amount of impurities carried by the initial runoff, and the limited flow area can easily induce waterlogging on the road surface; although some devices have overflow gaps, they lack effective dynamic sealing and filtration replenishment under heavy load conditions, making it easy for impurities to be discharged into the pipe network with the overflow water, causing secondary pollution; therefore, those skilled in the art provide a sewage interception device for sponge cities to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of high operation and maintenance costs caused by the difficulty in monitoring the accumulated sewage status of existing sewage interception devices, and the easy blockage of fixed flow holes leading to flooding under heavy rain conditions, and to propose a sewage interception device for sponge cities.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sewage interception device for sponge cities, comprising: A support base is used for installation on the inner wall of the drain outlet, and the support base is equipped with elastic support components; The wastewater trap is movably suspended from the bottom of the support base by elastic support members. Driven by the internal wastewater load, the wastewater trap has the freedom to move downward relative to the support base. A dirt accumulation indicator is installed on the top of the support base and is linked to the dirt interception basket. It is used to generate displacement when the dirt interception basket moves down, so as to display the dirt accumulation load indicator. The supplementary filter element is installed in the support base and includes a winding assembly rotatably installed in the support base and a filter belt wound on the winding assembly. The free end of the filter belt is connected to the top of the intercepting basket. The winding assembly unwinds or rewinds the filter belt synchronously with the lifting and lowering displacement of the intercepting basket.

[0006] As a further description of the aforementioned sewage interception device for sponge cities: The winding assembly includes a shaft rotatably mounted on a support base, with a drive gear connected to one end of the shaft extending outside the support base.

[0007] As a further description of the aforementioned sewage interception device for sponge cities: The intercepting basket is fixedly installed with multiple sets of drive racks that mesh one-to-one with the drive gears. The outer ring of the support base is provided with a guide rail. The drive rack is connected to a slide rod that is slidably installed on the guide rail to constrain the intercepting basket to make linear reciprocating motion in the vertical direction.

[0008] As a further description of the aforementioned sewage interception device for sponge cities: The filter belt includes several limiting baffles fixedly installed on the outer periphery of the rotating shaft. The limiting baffles are arranged at equal intervals along the axial direction of the rotating shaft. Between two adjacent sets of limiting baffles, there is a set of elastic bands wrapped around the rotating shaft. The free end of the elastic band is connected to the top inner ring of the intercepting basket.

[0009] As a further description of the aforementioned sewage interception device for sponge cities: The inner ring of the support base is provided with a shielding plate for shielding the replacement filter element. The shielding plate is connected to the bottom of the support base with a scraper. The scraper has a guide slit for the elastic band to pass through, and the edge of the guide slit is in contact with the surface of the elastic band.

[0010] As a further description of the aforementioned sewage interception device for sponge cities: The top surface of the sewage interception basket is equipped with a first sealing ring and a second sealing ring. When the sewage interception basket is in the initial high position, the first sealing ring presses against the bottom of the baffle plate, and the second sealing ring presses against the bottom of the support base.

[0011] As a further description of the aforementioned sewage interception device for sponge cities: The dirt accumulation indicator includes a display shaft rotatably mounted on a baffle plate, a lever fixedly mounted on the display shaft, the lever being connected to the dirt trap basket via a hinged first connecting rod, and an indicator mark on the outer circumferential surface of the display shaft.

[0012] As a further description of the aforementioned sewage interception device for sponge cities: Two sets of display axes are symmetrically installed on the top of the support base. Both sets of display axes are connected to the intercepting basket through their respective levers and first connecting rods. The inner bottom surface of the intercepting basket is fixedly installed with mounting bases that are hinged to the bottom ends of the two sets of first connecting rods.

[0013] As a further description of the aforementioned sewage interception device for sponge cities: Two sets of elastic support components are symmetrically installed on both sides of the support base. The elastic support components include spring guide columns fixedly installed on the side of the support base. The movable end of the spring guide column is connected to the sewage interception basket through a hinged second connecting rod.

[0014] As a further description of the aforementioned sewage interception device for sponge cities: Magnetic strips are fixedly installed on both sides of the bottom of the support base, and the sewage interception basket is made of magnetically conductive metal material that can be attracted by the magnetic strips.

[0015] In summary, due to the adoption of the above-mentioned sewage interception device for sponge cities, the beneficial effects of this invention are: By setting up a movable intercepting basket and a corresponding sewage accumulation indicator, the hidden underground sewage accumulation process can be transformed into a visible rotational motion on the ground. This allows maintenance personnel to accurately grasp the intercepting load without opening the grates, which not only avoids sewage interception failure due to untimely cleaning but also reduces the waste of manpower from blind inspections, greatly improving the precision of municipal maintenance. The further designed supplementary filter can adaptively compensate for the gaps created at the top when the intercepting basket moves down. During the sinking of the intercepting basket 11, the circular filter barrier dynamically seals the overflow path, ensuring effective filtration "at all times and at all heights," and completely solving the problem of secondary pollution caused by impurities escaping into the pipe network with the overflow water flow. Under heavy rain conditions, the significant drop of the intercepting basket can trigger the full deployment of the filter belt. At this time, the filter belt is stretched under force, and the pore size of its filter holes can expand, and the instantaneous effective flow area of ​​the device reaches its peak. While retaining the sewage interception function, it maximizes the instantaneous drainage capacity, effectively alleviating the problem of road flooding under extreme weather conditions.

Detailed Implementation

[0018] The following will describe, with reference to the accompanying drawings of the embodiments of the present invention, a sewage interception device for sponge cities according to the present invention in a clear and complete manner. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-8 As shown, the present invention provides a sewage interception device for sponge cities, including a support base 10, a sewage interception basket 11, a sewage accumulation indicator 30, and a supplementary filter element 40, etc.; wherein, the support base 10 is used to install on the inner wall of the drain outlet, and a grid can be placed on its top, and an elastic support element 20 is provided on the support base 10; the sewage interception basket 11 is movably suspended from the bottom of the support base 10 through the elastic support element 20, and the sewage interception basket 11 has the degree of freedom to move downward relative to the support base 10 under the drive of the internal sewage accumulation load, and the sewage accumulation indicator 30 is disposed on the top of the support base 10 and is linked to the sewage interception basket 11, and is used to generate displacement when the sewage interception basket 11 moves downward, so as to display the sewage accumulation load indicator.

[0020] In rainless or lightly rainy conditions, the trapping basket 11 accumulates relatively little dirt. At this time, the upward force provided by the elastic support 20 is greater than the weight of the trapping basket 11 and its internal impurities, allowing the trapping basket 11 to be securely locked in a high position close to the bottom of the support base 10. At this time, the dirt accumulation indicator 30 is hidden or in its initial zero position, and the device performs its conventional filtration and trapping function. However, as the amount of trapped impurities continues to increase, or as the trapping basket 11 traps more impurities and its water flow capacity decreases, water accumulation and backlog can easily occur inside, leading to a significant increase in the overall load. The total load of the trapping basket 11 reaches a preset threshold. Gravity can overcome the supporting force of the elastic support 20, causing the trapping basket 11 to move vertically downwards. During this downward movement, the trapping basket 11 drives the dirt accumulation indicator 30 to operate, gradually revealing a conspicuous indicator from the top of the support base 10, allowing staff to quickly identify the dirt accumulation status inside the trapping basket 11.

[0021] Correspondingly, the supplementary filter element 40 is disposed within the support base 10, including a winding assembly 401 rotatably mounted within the support base 10 and a filter belt 402 wound on the winding assembly 401. The free end of the filter belt 402 is connected to the top end of the intercepting basket 11. When the intercepting basket 11 moves downward, the winding assembly 401 is driven to unwind and rotate the filter belt 402, so that the filter belt 402 is stretched and dynamically closes the gap between the support base 10 and the intercepting basket 11. When the intercepting basket 11 moves upward, the winding assembly 401 is driven to rewind and rotate the filter belt 402.

[0022] The winding assembly 401 of the supplementary filter element 40 can be coupled to the intercepting basket 11 through a corresponding mechanical transmission mechanism. When the intercepting basket 11 moves downward due to the gravity of accumulated dirt, its downward displacement is synchronously converted into the rotational angular displacement of the winding assembly 401. This forced displacement constraint ensures that the unwinding length of the filter belt 402 is precisely matched with the drop height of the basket, which can prevent the filter belt from becoming loose or folded due to uneven gravity or water flow disturbance. After the filter belt 402 is pulled out from the winding assembly 401, it forms a ring-shaped filter barrier between the support base 10 and the intercepting basket 11, which can block the overflow gap that would otherwise cause impurities to escape. Under heavy rain conditions, the intercepting basket 11 drops significantly, and the filter belt 402 fully unfolds with the basket's displacement, reaching its peak equivalent cross-sectional area. This maximizes the instantaneous drainage capacity of the entire device, thereby achieving a maximum adaptive response to peak rainfall flow. This prevents the intercepting basket 11 from becoming completely blocked under heavy rain conditions. The supplementary filter element 40 retains the interception function of the intercepting device under heavy rain conditions and can quickly clear water flow to prevent road flooding.

[0023] In one embodiment, such as Figures 3-8As shown, specifically, the winding assembly 401 includes a rotating shaft 4011 rotatably mounted on the support base 10. One end of the rotating shaft 4011 extending outside the support base 10 is connected to a drive gear 4012. The drive gear 4012 can be directly welded or detachably mounted to the end of the rotating shaft 4011. Correspondingly, multiple sets of drive racks 12 are fixedly mounted on the wastewater trap 11, each meshing with a corresponding drive gear 4012. A guide rail 13 is provided on the outer ring of the support base 10. The drive racks 12 are connected to slide rods 14 slidably mounted on the guide rail 13 to constrain the wastewater trap 11 to perform linear reciprocating motion in the vertical direction.

[0024] Through the meshing of the drive rack 12 and the drive gear 4012, the drive gear 4012 controls the rotation of the rotating shaft 4011 and the connected filter belt 402, which can convert the vertical gravitational displacement of the intercepting basket 11 into the rotational power of the rotating shaft 4011. The rigid connection of the gear and rack ensures the precise proportional relationship between the unwinding speed and the sinking speed. The gear transmission can also effectively prevent lateral displacement and slippage caused by water flow impact, ensuring that the filter belt 402 can be stably and uniformly unfolded even under extreme flood peak flow. The ratio of the circumference of the drive gear 4012 to the circumference of the rotating shaft 4011 can be matched with the preset stretch ratio of the elastic belt 4022 to ensure that when the intercepting basket 11 sinks to a certain length, the filter belt 402 can be unwound to the required length without sagging.

[0025] Specifically, the filter belt 402 includes several limiting baffles 4021 fixedly installed on the outer periphery of the rotating shaft 4011. These limiting baffles 4021 are arranged at equal intervals along the axial direction of the rotating shaft 4011. Between adjacent sets of limiting baffles 4021, there is a set of elastic bands 4022 wound around the rotating shaft 4011. The free end of the elastic band 4022 is connected to the inner top ring of the intercepting basket 11. The end of each elastic band 4022 can be directly fixed or detachably installed onto the intercepting basket 11. By arranging several elastic bands 4022 separately and axially constrained by the limiting baffles 4021, independent winding units can be formed on the rotating shaft 4011. The spacing between adjacent elastic bands 4022 is the size of the water-passing mesh. The limiting baffles 4021 prevent axial movement or uneven stacking of the elastic bands 4022 during frequent winding and unwinding, ensuring reliable long-term operation. Meanwhile, if one of the elastic bands 4022 is damaged, the remaining bands can still function normally, improving the device's fault tolerance and maintenance flexibility.

[0026] Based on the above embodiments, such as Figures 5-7As shown, the inner ring of the support base 10 is provided with a baffle plate 15 for shielding the supplementary filter element 40. The baffle plate 15 is connected to the bottom of the support base 10 by a scraper 16. The connection between the components can be directly welded. The four side baffles of the support base 10 can be easily disassembled for assembly, facilitating subsequent inspection and maintenance of the internal components. The scraper 16 has a guide slot 17 for the elastic band 4022 to pass through, and the edge of the guide slot 17 is in contact with the surface of the elastic band 4022. The baffle plate 15, the scraper 16, and the inner wall of the support base 10 together form a relatively independent accommodating cavity, which encloses the supplementary filter element 40. This prevents the high-speed water flow and coarse impurities rushing down from the grid from directly impacting the winding shaft, avoiding physical damage to the mechanical structure; the supplementary filter element 40 is also effectively extended in its actual service life by being in a sealed cavity for a long time.

[0027] The scraper 16 serves as the bottom cover of the cavity. Its guide slot 17 forms an interference fit or tight fit with the elastic band 4022. When the intercepting basket 11 moves upward and resets, the elastic band 4022 must pass through the guide slot 17. At this time, the edge of the slot acts like a scraper, which can forcibly peel off the sticky sludge and fine fibers attached to the surface of the band and leave them outside the cavity, which helps to maintain the reliability of the winding and unwinding of the elastic band 4022. The inner wall of the guide slot 17 of the scraper 16 can be covered with a Teflon anti-friction layer or made of flexible silicone material, and its edge design can be a wedge-shaped scraper. This design can not only ensure strong peeling of sticky sludge, but also form a water film lubrication on the surface of the elastic band 4022, reduce the rewinding resistance, and protect the band from mechanical damage.

[0028] The top surface of the intercepting basket 11 is provided with a first sealing ring 18 and a second sealing ring 19. When the intercepting basket 11 is in its initial high position, the first sealing ring 18 presses upward against the bottom of the baffle plate 15, and the second sealing ring 19 presses upward against the bottom of the support base 10. The first sealing ring 18 is located on the inner side of the top edge of the intercepting basket 11. In the initial state, the upward pre-tightening force provided by the elastic support member 20 can make the sealing ring and the bottom of the baffle plate 15 form a tight end face press, which is used to intercept splashed sewage and fine particles from entering the guide gap 17. The second sealing ring 19 is located on the outer side of the top edge of the intercepting basket 11 and directly abuts against the support base 10. It can be used to seal the physical gap between the support base 10 and the intercepting basket 11. The inner and outer sealing rings can also play a role in flexible limiting and impact buffering when the intercepting basket 11 is controlled to reset by the elastic support member 20, effectively avoiding rigid impact between metal components.

[0029] In one embodiment, such as Figures 1-6As shown, specifically, the dirt accumulation indicator 30 includes a display shaft 301 rotatably mounted on a baffle plate 15. A fixing block rotatably connected to the display shaft 301 can be welded onto the baffle plate 15. A lever 305 is fixedly mounted on the display shaft 301. The lever 305 is connected to the dirt trap basket 11 via a hinged first connecting rod 302. An indicator mark 303 is provided on the outer circumferential surface of the display shaft 301. Furthermore, two sets of display shafts 301 are symmetrically mounted on the top of the support base 10. Both sets of display shafts 301 are connected to the dirt trap basket 11 via their respective levers 305 and first connecting rods 302. A mounting seat 304 hinged to the bottom end of the two sets of first connecting rods 302 is fixedly mounted on the inner bottom surface of the dirt trap basket 11. Mesh holes for accommodating the display shafts 301 can be reserved in the grid laid on the support base 10, making it easy to expose the display shafts 301 in a position that is easy to observe.

[0030] The sewage interception basket 11 moves vertically in a linear motion. Through two sets of first connecting rods 302 and levers 305 hinged to the mounting base 304, the linear displacement of the basket is transmitted to the display shaft 301. The levers 305, controlled by the first connecting rods 302, drive the display shaft 301 to rotate. Figure 5 As shown, for every unit distance the trap basket 11 moves downward, the display shaft 301 is forced to rotate accordingly, causing the indicator marks 303 on the outer ring of the display shaft 301 to gradually flip into view. This transforms what is difficult to observe into something clearly visible. By observing the rotation angle of the display shaft 301, workers can not only determine whether the trap basket 11 is fully loaded, but also predict the rate of dirt accumulation based on the degree to which the indicator is visible, enabling preventative maintenance. The indicator marks 303 can be reflective strips affixed to the outside of the display shaft 301 or painted with a conspicuous color.

[0031] To ensure the stability of the sewage interceptor basket 11 during use, two sets of elastic support members 20 are symmetrically installed on both sides of the support base 10, such as... Figures 1-5 As shown, specifically, the elastic support member 20 includes a spring guide post 201 fixedly installed on the side of the support base 10. The movable end of the spring guide post 201 is connected to the intercepting basket 11 via a hinged second connecting rod 202. The spring guide post 201 provides upward support force to the intercepting basket 11 through the spring and the telescopic rod of the inner spring ring. When the intercepting basket 11 moves downward, the spring and telescopic rod can be compressed through the second connecting rod 202. The multiple sets of elastic support members 20 can provide a stable and reliable elastic support force for the intercepting basket 11. Moreover, the elastic support member 20 is located on the backwater side of the support base 10, and it is not easily damaged even after long-term use.

[0032] Magnetic strips 110 are fixedly installed on both sides of the bottom of the support base 10. The trap basket 11 is made of a magnetically conductive metal material that can be attracted by the magnetic strips 110. When there is no or little accumulated dirt, the trap basket 11 is at its highest position under the thrust of the elastic support 20. At this time, the magnetic strips 110 and the top edge of the magnetically conductive metal trap basket 11 generate a strong magnetic attraction, forming a certain locking effect. In actual working conditions, there are often intermittent small-flow water impacts inside the trap basket 11. Without the magnetic strips 110, the trap basket 11 would frequently sway slightly up and down with the water flow. The magnetic strips 110 provide initial rigidity to the trap basket 11, avoiding frequent mechanical wear of structures such as the gear rack, winding assembly 401, and elastic band 4022 under slight disturbances, thus significantly extending the service life of the components.

[0033] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the present invention's concept of a sewage interception device for sponge cities, should be covered within the scope of protection of the present invention.
