Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a high-efficiency flow guiding filtration device for rainwater pipe networks. Background Technology

[0002] High-efficiency stormwater drainage and filtration devices are environmentally friendly facilities installed at urban stormwater inlets, manholes, or upstream of drainage systems. They are primarily used to intercept solid debris such as leaves, plastics, and silt in rainwater, preventing them from entering downstream pipe networks and causing blockages. While achieving high-efficiency filtration, these devices optimize the flow channel structure (such as inclined filter plates, guide channels, and swirling sedimentation zones) and utilize the scouring force and gravity of rainwater to allow intercepted materials to automatically slide off or concentrate in the collection area. They possess a certain degree of self-cleaning capability. Some designs also incorporate non-powered swinging, vibration, or flipping mechanisms to further prevent filter clogging and ensure smooth drainage during heavy rains. They are widely used in sponge city construction scenarios such as roads, squares, and residential areas, and are an important infrastructure for improving urban drainage resilience and reducing the risk of urban flooding.

[0003] In urban stormwater drainage systems, storm drains or wells are often clogged by debris such as leaves, plastic bags, and silt, leading to poor drainage and even flooding. Traditional stormwater filtration devices mostly use fixed screens or grilles, which can intercept impurities but lack self-cleaning capabilities, requiring frequent manual cleaning, resulting in high maintenance costs and slow response times. Especially during heavy rain, a large amount of debris accumulates instantly, easily causing the screens to fail quickly. At the same time, if the filtration structure is not designed properly, it can also increase water flow resistance and affect drainage efficiency. With the advancement of sponge city and smart drainage construction, how to achieve automatic anti-clogging and efficient flow diversion of filtration devices using the kinetic energy of rainwater itself without relying on external energy sources has become a key technical challenge to improve the reliability and low maintenance of urban stormwater pipe networks.

[0015] 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.

[0016] Please see Figures 1 to 5 This utility model provides a technical solution: A high-efficiency flow guiding and filtering device for rainwater pipe network includes a pipe 1. A connecting rod 2 is fixedly installed on the right end face of the pipe 1. A filter plate 3 is fixedly installed on the upper side of the inside of the pipe 1. A flow guiding plate 4 is set on the lower side of the filter plate 3. The flow guiding plate 4 is fixedly connected to the pipe 1. A rotating shaft 5 is set on the lower side of the flow guiding plate 4. A blade 6 is fixedly installed on the outer surface of the rotating shaft 5. The rotating shaft 5 is rotatably connected to the pipe 1. Support rods 7 are fixedly installed on both sides of the pipe 1. A reciprocating screw 8 is rotatably connected between the support rod 7 and the pipe 1. The ends of the two sets of reciprocating screws 8 extend into the inside of the pipe 1 and are fixedly connected to the two ends of the rotating shaft 5 respectively. A threaded sleeve 9 is helically driven on the outer surface of the reciprocating screw 8. A connecting rod 10 is rotatably connected to the outer side of the threaded sleeve 9.

[0017] A clamping rod 11 is provided on the right side of the pipe 1. A connecting groove 16 is provided at the lower end of the clamping rod 11. Both sets of connecting rods 10 are rotatably connected to the connecting groove 16.

[0018] A crossbar 13 is slidably connected to the upper side of the filter plate 3. A push rod 12 is fixedly installed between the crossbar 13 and the clamping rod 11. The push rod 12 is slidably connected to the pipe 1.

[0019] The left end face of the pipe 1 is connected to the discharge port 14, which is set corresponding to the crossbar 13.

[0020] A storage groove 18 is provided on the lower end face of the crossbar 13, and a scraper 19 is slidably connected inside the storage groove 18.

[0021] An airbag 15 is fixedly installed between the clamp rod 11 and the pipe 1, and a connecting pipe 17 is provided between the airbag 15 and the storage groove 18.

[0022] Rainwater is collected and flows into the pipe 1. After being filtered by the filter plate 3, it continues to fall and is guided by the diverter plate 4 to the blade 6, which washes the blade 6 on the rotating shaft 5, causing the rotating shaft 5 to rotate. The rotating shaft 5 will then carry two sets of reciprocating screws 8 to rotate, and the threaded sleeves 9 on the reciprocating screws 8 will move. The two sets of threaded sleeves 9 will initially move towards each other. When they reach the end of the reciprocating screws 8, they will change to relative motion due to the characteristics of the reciprocating screws 8. As the reciprocating screws 8 continue to rotate, the two sets of threaded sleeves 9 will continuously switch between moving towards each other and relative motion. The threaded sleeves 9 will carry the connecting rod 10 to move, and the two sets of connecting rods 10 are rotatably connected to the connecting groove 16 on the clamping rod 11, thus driving the clamping rod 11 to reciprocate. The clamping rod 11 will then push the crossbar 13 to reciprocate through the push rod 12. When the clamp moves towards the pipe 1, it squeezes the air bladder 15, expelling the gas inside the air bladder 15 into the collection tank 18 through the connecting pipe 17. This causes the scraper 19 to extend and scrape and clean the filter plate 3, pushing impurities towards the discharge port 14. When the clamp moves away from the pipe 1, the air bladder 15 expands, and the gas inside the collection tank 18 is drawn back into the air bladder 15. The scraper 19 rises and retracts into the collection tank 18, preventing impurities from being scraped to the right side of the pipe 1. Thus, with the continuous collection of rainwater, the filter plate 3 can be continuously cleaned, preventing it from becoming clogged.

[0023] In urban stormwater drainage systems, storm drains or wells often become clogged with debris such as leaves, plastic bags, and silt, leading to poor drainage and even flooding. Traditional stormwater filtration systems mostly use fixed filters or grilles, which can intercept impurities but lack self-cleaning capabilities, requiring frequent manual cleaning, resulting in high maintenance costs and slow response times. Especially during heavy rain, the rapid accumulation of debris can easily cause filters to fail quickly. Furthermore, an improperly designed filtration structure can increase water flow resistance and affect drainage efficiency. With the advancement of sponge city and smart drainage construction, the question arises: how can we utilize the natural flow of rainwater without relying on external energy sources? Achieving automatic anti-clogging and efficient flow diversion of the filtration device has become a key technical challenge in improving the reliability and low maintenance of urban rainwater pipe networks. Therefore, this utility model intercepts impurities in the collected initial rainwater by setting up a filtration device, effectively preventing leaves, mud, and other debris from clogging the downstream pipe 1. The device cleverly utilizes the scouring force and gravity of the rainwater itself to clean the filter plate 3, avoiding filter clogging. The structure requires no external power, has strong self-cleaning ability, and ensures continuous and efficient rainwater diversion. It is suitable for rainwater inlets or drainage wells in sponge city construction such as urban roads, squares, and residential areas, improving the operational reliability and maintenance convenience of the drainage system.

[0024] Working principle: Rainwater is collected and flows into the pipe 1. After being filtered by the filter plate 3, it continues to fall and is guided by the diversion plate 4 to the blade 6, which washes the blade 6 on the rotating shaft 5, causing the rotating shaft 5 to rotate. The rotating shaft 5 will then carry two sets of reciprocating screws 8 to rotate, and the threaded sleeves 9 on the reciprocating screws 8 will move. The two sets of threaded sleeves 9 will initially move towards each other. When they reach the end of the reciprocating screws 8, they will change to relative motion due to the characteristics of the reciprocating screws 8. As the reciprocating screws 8 continue to rotate, the two sets of threaded sleeves 9 will continuously switch between moving towards each other and relative motion. The threaded sleeves 9 will carry the connecting rod 10 to move, and the two sets of connecting rods 10 are rotatably connected to the connecting groove 16 on the clamping rod 11. Therefore, the clamping rod 11 will be driven to reciprocate. The clamping rod 11 will then push the crossbar 13 to reciprocate through the push rod 12. When the clamp moves towards the pipe 1, it squeezes the air bladder 15, expelling the gas inside the air bladder 15 into the collection tank 18 through the connecting pipe 17. This causes the scraper 19 to extend and scrape and clean the filter plate 3, pushing impurities towards the discharge port 14. When the clamp moves away from the pipe 1, the air bladder 15 expands, and the gas inside the collection tank 18 is drawn back into the air bladder 15. The scraper 19 rises and retracts into the collection tank 18, preventing impurities from being scraped to the right side of the pipe 1. Thus, with the continuous collection of rainwater, the filter plate 3 can be continuously cleaned, preventing it from becoming clogged.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
