Technical Field
[0001] This utility model relates to the field of rainwater diversion and discharge technology for sponge cities, and in particular to a rainwater diversion and discharge device for sponge cities. Background Technology
[0002] A sponge city refers to a new urban construction model that uses a variety of technologies such as infiltration, retention, storage, purification, utilization, and drainage to make a city like a sponge, with good "elasticity" in adapting to environmental changes and responding to natural disasters. It can flexibly absorb, store, infiltrate, and purify water, and release and utilize the stored water when needed. The rainwater diversion and discharge device in a sponge city is one of the core devices for rainwater management in the construction of a sponge city. It mainly targets the classification, collection, diversion, treatment, and targeted discharge of rainwater at different times and with different levels of pollution during urban rainfall, in order to achieve the goals of mitigating urban flooding, controlling pollution, and efficiently utilizing water resources.
[0003] A search revealed Chinese patent publication number CN222500525U, which discloses a sponge city rainwater diversion and discharge device. The device includes an infiltration tank. A first filter and a second filter are slidably connected to the inner wall of the infiltration tank. Four limiting frames are fixedly installed on the inner wall of the infiltration tank. Each limiting frame has four buffer springs fixedly installed on its inner bottom wall. The tops of the two sets of buffer springs are fixedly connected to the bottom surfaces of the first and second filters, respectively. A stepper motor is fixedly installed on the inner wall of the infiltration tank. The output end of the stepper motor passes through the infiltration tank and has a movable rod fixedly installed thereon. Two support rods are fixedly installed on the outer surface of the movable rod. A collection rack is slidably connected to the inner wall of the infiltration tank. This invention uses a stepper motor to drive the movable rod to rotate, thereby causing the support rods to rotate and strike the first and second filters, enabling continuous automatic cleaning of impurities on the first and second filters. However, the existing cleaning devices, where the stepper motor drives the support rods to rotate and strike, cannot effectively remove strongly adhered dirt from the filter surface, leading to dirt and impurities clogging the filters. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a rainwater diversion and discharge device for sponge cities, which aims to improve the problem in the prior art where the rotation and impact of the support rod cannot effectively remove dirt with strong adhesion to the filter screen surface, thus causing dirt and impurities to clog the filter screen.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sponge city rainwater diversion and discharge device, comprising an infiltration tank, wherein multiple cleaning mechanisms are equidistantly installed inside the infiltration tank for cleaning dirt, a flushing mechanism is installed on the rear side of the outer wall of the infiltration tank for accelerating the outflow of wastewater and cleaning, and multiple collection mechanisms are equidistantly installed on the front side of the outer wall of the infiltration tank for collecting dirt; the cleaning mechanism includes a brush, which is equidistantly installed inside the infiltration tank, and a scraper is installed on the rear side of the outer wall of the brush; a drive assembly including a motor is installed on the rear side of the outer wall of the infiltration tank, and the output end of the motor is fixedly connected to a worm gear; a first infiltration filter is fixedly connected to the upper middle part of the inner wall of the infiltration tank, a second infiltration filter is fixedly connected to the upper middle part of the inner wall of the infiltration tank, multiple threaded rods are rotatably connected equidistantly to the inner wall of the infiltration tank, and worm gears are fixedly connected to the rear ends of the outer walls of the threaded rods; and multiple guide rods are fixedly connected equidistantly to the inner wall of the infiltration tank.
[0006] The above technical solution works as follows: after the motor starts, it drives the worm gear at the output end to rotate. The worm gear meshes with the worm wheel at the rear end of each threaded rod, thereby driving multiple threaded rods to rotate synchronously. When the threaded rods rotate, they drive multiple sets of brushes and scrapers to clean the internal filter screen of the infiltration box by brushing it synchronously from top to bottom. After the brushes remove the dirt on the filter screen, the scrapers finally scrape away the more stubborn dirt and impurities, maintaining the permeability of the filter screen. The guide rod passes through the brushes and scrapers to ensure that it moves in a straight line along the outer wall of the threaded rod.
[0007] As a further description of the above technical solution:
[0008] The flushing mechanism includes a drain pipe installed on the rear side of the outer wall of the infiltration tank. A T-shaped fixing plate is installed on the left side of the inner wall of the drain pipe. A fixing short column is fixedly connected to the rear side of the outer wall of the T-shaped fixing plate. An impeller is rotatably connected to the rear end of the outer wall of the fixing short column. A guide column is fixedly connected to the rear end of the outer wall of the impeller. Multiple bolts are threaded at equal intervals on the right side of the outer wall of the T-shaped fixing plate. Multiple cleaning blades are fixedly connected at equal intervals to the rear end of the outer wall of the impeller.
[0009] The above technical solution works as follows: When the sewage in the infiltration tank is discharged through the drain pipe, the water flow impacts the impeller blades. The guide column is located at the rear end of the impeller, guiding the water flow to form a vortex. The impeller drives the cleaning blades to rotate synchronously, scraping away the dirt on the pipe wall. The rotating cleaning blades generate centrifugal force, throwing the particles in the sewage toward the pipe wall. The flushing effect of the water flow accelerates the removal of impurities, which are then discharged from the pipe with the water flow. The cleaning blades continuously clean the pipe wall during rotation, preventing the accumulation of impurities that could lead to pipe diameter reduction or pipe blockage, thus maintaining smooth drainage.
[0010] As a further description of the above technical solution:
[0011] The collection mechanism includes a hollow box, which is equidistantly installed on the front side of the outer wall of the permeation tank. A sliding plate is slidably connected to the upper part of the inner wall of the hollow box. Multiple discharge slots are equidistantly opened on the front side of the outer wall of the permeation tank. A collection box is installed inside the hollow box.
[0012] Through the above technical solution: the collection box inside the hollow box can easily collect and store the dirt scraped off by the brush and scraper, and the sliding plate can seal the collection box when it is not in use to prevent water leakage.
[0013] As a further description of the above technical solution:
[0014] The outer wall of the collection box is slidably connected to the interior of the hollow box, and the bottom of the discharge trough is fixedly connected to the top of the hollow box.
[0015] The above technical solution allows for a sliding connection between the outer wall of the collection box and the interior of the hollow box, facilitating easy removal and use of the collection box by staff. The discharge chute provides fixed support for the hollow box.
[0016] As a further description of the above technical solution:
[0017] The worm gear meshes with the worm wheel, and the interior of the brush and scraper are threadedly connected to the outer wall of the threaded rod.
[0018] The above technical solution works by using a worm gear to drive a worm wheel to rotate synchronously. When the worm wheel rotates, it drives the threaded rod to rotate, and the rotation of the threaded rod drives the brush and scraper on the outer wall to move and remove the dirt attached to the filter screen.
[0019] As a further description of the above technical solution:
[0020] The upper part of the inner wall of the brush and scraper is slidably connected to the outer wall of the guide fixing rod, and multiple leakage grooves are equidistantly opened on the top of the infiltration box.
[0021] Through the above technical solution: the guide and fixing rods restrict the movement trajectory of the brush and scraper, thereby ensuring that the brush and scraper can move smoothly; the leakage grooves equidistantly opened on the top of the infiltration box can facilitate the collection of rainwater.
[0022] As a further description of the above technical solution:
[0023] A support plate is fixedly connected to the rear side of the outer wall of the infiltration tank, and the top of the support plate is fixedly connected to the bottom of the motor.
[0024] Through the above technical solution, the supporting square plate serves to support and fix the motor.
[0025] This utility model has the following beneficial effects:
[0026] 1. In this utility model, after the motor is started, it drives the worm to rotate and mesh with the worm wheel, and the threaded rod rotates synchronously. The threaded rod drives the brush and scraper to clean the filter screen of the infiltration box. After the brush removes the dirt, the scraper removes the residual impurities and maintains the permeability of the filter screen. The guide rod ensures that the brush and scraper move in a straight line along the threaded rod, thereby avoiding the problem that the dirt with strong adhesion to the filter screen cannot be effectively peeled and removed due to the rotation and impact of the support rod, which would lead to the problem of dirt and impurities clogging the filter screen.
[0027] 2. In this utility model, when sewage is discharged through the drain pipe, it impacts the impeller blades, and the guide column guides the water flow to form a vortex. The impeller drives the cleaning blade to rotate, scraping and removing dirt from the pipe wall. The rotating cleaning blade generates centrifugal force, throwing particles toward the pipe wall, accelerating the shedding of impurities, and discharging them with the water flow. The cleaning blade continuously cleans the pipe wall, preventing the accumulation of impurities that could lead to pipe diameter reduction or blockage, maintaining smooth drainage, avoiding the need for regular manual pipe cleaning, and reducing the workload of operation and maintenance.

[0037] Specifically, after the motor 2031 is started, it drives the worm gear 2032 at the output end to rotate. The worm gear 2032 meshes with the worm wheel 2033 at the rear end of each threaded rod 2034, thereby driving the synchronous rotation of multiple threaded rods 2034. When the threaded rods 2034 rotate, they drive multiple sets of brushes 201 and scrapers 202 to simultaneously brush and clean the internal filter screen of the infiltration box 1 from both the top and bottom. After the brushes 201 brush away the dirt on the filter screen, the scrapers 202 finally scrape away the more stubborn dirt and impurities, maintaining the permeability of the filter screen.

[0039] Specifically, when the wastewater in the infiltration tank 1 is discharged through the drain pipe 301, the water flow impacts the blades of the impeller 307. The guide column 306 is located at the rear end of the impeller 307, guiding the water flow to form a vortex. The impeller 307 drives the cleaning blade 304 to rotate synchronously, scraping away dirt on the pipe wall. The rotating cleaning blade 304 generates centrifugal force, throwing particles in the wastewater against the pipe wall. The flushing effect of the water flow accelerates the removal of impurities, which are then discharged from the pipe with the water flow. The cleaning blade 304 continuously cleans the pipe wall during rotation, preventing the accumulation of impurities that could lead to pipe diameter reduction or blockage, thus maintaining smooth drainage. The outer wall of the collection box 403 is slidably connected to the interior of the hollow box 401, and the bottom of the discharge trough 404 is connected to the hollow box 401. The top of the core box 401 is fixedly connected, and the outer wall of the collection box 403 is slidably connected to the inside of the hollow box 401, which facilitates the removal of the collection box 403 by the staff for use.

The rotation of the threaded rod 2034 will drive the brush 201 and the scraper 202 on the outer wall to move and remove the dirt attached to the filter screen.
[0040] Reference Figure 1 , Figure 2 and Figure 3 The upper part of the inner wall of the brush 201 and the scraper 202 is slidably connected to the outer wall of the guide fixing rod 2035.

[0042] Working principle: After the motor 2031 is started, it drives the worm 2032 at the output end to rotate. The worm 2032 meshes with the worm wheel 2033 at the rear end of each threaded rod 2034, thereby driving the synchronous rotation of multiple threaded rods 2034. When the threaded rods 2034 rotate, they drive multiple sets of brushes 201 and scrapers 202 to clean the internal filter screen of the infiltration box 1 by brushing it from top to bottom. After the brushes 201 brush away the dirt on the filter screen, the scrapers 202 scrape away the more stubborn dirt and impurities, maintaining the permeability of the filter screen. The guide rod 2035 passes through the brushes 201 and scrapers 202, ensuring that it moves in a straight line along the outer wall of the threaded rods 2034. This avoids the problem of dirt and impurities clogging the filter screen due to the rotation and impact of the support rod, which may not be able to effectively peel off and remove the dirt with strong adhesion to the filter screen surface.
[0043] When the sewage in the infiltration tank 1 is discharged through the drain pipe 301, the water flow impacts the blades of the impeller 307. The guide column 306 is located at the rear end of the impeller 307, guiding the water flow to form a vortex. The impeller 307 drives the cleaning blade 304 to rotate synchronously, scraping away the dirt on the pipe wall. The rotating cleaning blade 304 generates centrifugal force, throwing the particles in the sewage toward the pipe wall.
