Description

Technical Field

[0001] This utility model belongs to the field of water supply and drainage technology, specifically relating to a rainwater pipe filter assembly that is easy to maintain. Background Technology

[0002] Sponge city is a modern urban stormwater management concept that aims to improve a city's adaptability to extreme rainfall and climate change by mimicking the water absorption, storage, infiltration, and purification functions of natural ecosystems, while alleviating problems such as urban flooding and water shortages.

[0003] With the rapid development of cities, a series of environmental problems such as urban flooding, black and odorous water bodies, and damage to aquatic ecosystems have become increasingly prominent. In municipal drainage systems, rainwater pipes, as an important auxiliary structure of the drainage pipe system, directly determine the drainage capacity of the drainage pipe system by their ability to effectively collect water and efficiently transport surface rainwater runoff to the municipal drainage pipe system.

[0004] A prior art patent, CN216726130U, describes a filtration pipe for water conservancy projects. It includes a filter screen mounting box and connecting pipes on both sides of the box. The connecting pipes are integrally formed and fixedly connected to the filter screen mounting box. A fixing frame is welded to the opening of each connecting pipe, and a rotating shaft is rotatably mounted on the fixing frame. A turntable is rotatably mounted on the rotating shaft. Multiple fan blades and connecting rods are evenly welded to the side wall of the turntable, and scrapers are welded to the ends of the connecting rods. A filter screen is installed in the filter screen mounting box. This patent uses water flow to drive the fan blades to rotate, which in turn drives the turntable to rotate. The turntable, through the connecting rods, drives the scrapers to rotate, thus cleaning the inside of the connecting pipe and preventing impurities from adhering to its inner wall. However, in practical use, this patent still has the following shortcomings: From a practical standpoint, it cannot control the water flow speed within the pipe or determine the size of impurities. High-velocity, large impurities can impact and damage the device and filter screen, affecting the filtration effect and increasing pipe maintenance costs.

[0005] Therefore, there is a need for a rainwater pipe filtration assembly that is easy to maintain, in order to solve the problems of inconvenience in controlling the flow rate inside the pipe and inconvenience in maintaining and cleaning the filter screen in the existing technology.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Please see Figure 1-6 This utility model provides a rainwater pipe filter assembly that is easy to maintain, including a water supply pipe 1, a tapered pipe 3, and an adjusting pipe 6. An underwater sensor 2 is fixedly connected to the top of the water supply pipe 1, and the underwater sensor 2 penetrates inside the water supply pipe 1. The underwater sensor 2 is a Xylem SonTek-IQ model and is used to monitor the pipe flow. The right side of the tapered pipe 3 is fixedly connected to the left side of the water supply pipe 1, and the left side of the tapered pipe 3 is fixedly connected to the right side of the adjusting pipe 6. A maintenance pipe 7 is fixedly connected to the bottom left side of the adjusting pipe 6, and an inspection cover 8 is threadedly connected to the bottom end of the maintenance pipe 7. An adjusting mechanism 4 is fixedly connected to the top of the adjusting pipe 6, and a filtering mechanism 5 is fixedly connected to the left side of the adjusting pipe 6.

[0029] Specifically, underwater sensor 2 monitors the flow velocity range (0.5-5m / s) and turbidity threshold (≥50NTU) in real time, and performs the following actions through PLC controller (not shown): when the flow velocity is >3m / s, it controls motor 421 to drive baffle 417 to rotate to a 45° tilt angle, so that the flow velocity is reduced by 30% to 50%; when the turbidity exceeds the standard, it triggers an audible and visual alarm (not shown) to prompt the cleaning and maintenance of sediment in pipe 7.

[0030] Alternatively, the inspection cover 8 can be replaced with a pneumatic quick-opening flange (not shown), equipped with a pressure sensor, which automatically opens to drain when the sediment height is greater than 1 / 3 of the pipe diameter.

[0031] The filter mechanism 5 includes a filter component 51 and an installation component 52. The right side of the installation component 52 is fixedly connected to the left side of the regulating pipe 6, and the filter component 51 is inserted into the installation component 52.

[0032] The regulating mechanism 4 includes a rotating component 41 and a control component 42. The rotating component 41 is disposed inside the regulating pipe 6, and the control component 42 is fixedly connected to the top of the regulating pipe 6.

[0033] Further as Figure 2 , Figure 5 and Figure 6 As shown, it is worth noting that the rotating assembly 41 includes a sealed bearing 413. The outer ring of the sealed bearing 413 is fixedly connected to the regulating pipe 6, and the inner ring of the sealed bearing 413 is fixedly connected to a rotating shaft 412. A driven bevel gear 411 is fixedly connected to the top of the rotating shaft 412. There are two sealed bearings 413, symmetrically distributed at the upper and lower ends of the rotating shaft 412. A waterproof sealing gasket 414 is fitted inside the sealed bearing 413 and the surface of the rotating shaft 412. A chuck 415 is provided inside the waterproof sealing gasket 414. A slot 416 is opened inside the chuck 415. A water baffle 417 is engaged in the slot 416. There are two water baffles 417, which are distributed on both sides of the rotating shaft 412.

[0034] The baffle plate 417 is made of 304 stainless steel with a thickness of 5mm and has a flow guide groove (not shown) on its surface to disperse the impact force of the water flow; the chuck 415 and the rotating shaft 412 transmit torque through a flat key structure to ensure the precise angle of the baffle plate 417.

[0035] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth noting that the control component 42 includes a base 423, which is fixedly connected to the top of the regulating pipe 6. A control motor 421 is fixedly connected to the top of the base 423. An active bevel gear 422 is fixedly connected to the output end of the control motor 421. The right side of the active bevel gear 422 meshes with the top of the driven bevel gear 411.

[0036] In use, the underwater sensor 2 monitors and provides feedback on the water flow speed. When the water flow speed is too fast, the underwater sensor 2 sends feedback to the control motor 421 of the control component 42. The output end of the control motor 421 is fixedly connected to the active bevel gear 422. The active bevel gear 422 drives the driven bevel gear 411, which is fixedly connected to the top of the rotating shaft 412, to rotate, thereby causing the rotating shaft 412 to rotate. Since the chuck 415 is fixedly connected to the surface of the rotating shaft 412, and the baffle plate 417 is inserted into the slot 416 opened on the surface of the chuck 415, the baffle plate 417 will rotate with the rotating shaft 412, thereby reducing the flow range in the pipe, thus reducing the water flow speed and the speed of impurities, and preventing damage to the filter screen 515.

[0037] According to the above working process, by monitoring the water flow inside the water pipe 1 by the underwater sensor 2, the water flow speed in the pipe is controlled by the regulating mechanism 4. Impurities with fast water flow speed are blocked by the baffle plate 417, which reduces the flow speed and prevents the filter screen 515 from being damaged by impact. The deposited impurities can be cleaned through the filter mechanism 5 and the maintenance pipe 7.

[0038] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the filter assembly 51 includes a top cover 511, which is located at the top of the housing 521. A handle 512 is fixedly connected to the top of the top cover 511, and a limiting plate 513 is fixedly connected to the bottom of the top cover 511. A circular through hole 514 is provided in the middle of the limiting plate 513, and a filter screen 515 is fixedly connected in the circular through hole 514. The top of the top cover 511 is flush with the top of the housing 521.

[0039] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the installation component 52 includes a flange 522, which is fixedly connected to the right side of the regulating pipe 6. A housing 521 is fixedly connected to the left side of the flange 522. Rotating pins 523 are fixedly connected to the front and rear sides of the top of the housing 521. A rotating block 524 is rotatably connected to the top of the rotating pins 523. Limit frames 526 are fixedly connected to the inside of the housing 521 on both sides. Sealing gaskets 525 are fixedly connected to the surface of the limit frames 526. There are two flanges 522, one on the left side of the housing 521 and the other on the right side. There are four rotating pins 523, distributed at the four corners of the top of the housing 521. There are two limit frames 526, distributed on both sides of the inside of the housing 521. The size of the limit plate 513 is the same as the size between the two limit frames 526.

[0040] In use, the rotating block 524 is rotated on the rotating pin 523 to release the limit on the top of the top cover 511, thereby making it easier to lift the handle 512 and remove the limit plate 513 inside the housing 521 to facilitate cleaning, maintenance and replacement of the filter screen 515, thereby improving its maintenance efficiency and convenience.

[0041] This solution has the following working process: When this device is in use, water flows into the water supply pipe 1, and the pipe diameter is enlarged by the conical pipe 3, thereby slowing down the water flow speed. The water flow speed is monitored and fed back by an underwater sensor 2 that is fixedly connected to the water supply pipe 1 and penetrates the inner wall of the pipe. When the water flow speed is too fast, the underwater sensor 2 feeds back to the control motor 421 of the control component 42. The output end of the control motor 421 is fixedly connected to the active bevel gear 422. The active bevel gear 422 drives the driven bevel gear that is fixedly connected to the top of the rotating shaft 412. The gear 411 rotates, causing the shaft 412 to rotate. Since the chuck 415 is fixedly connected to the surface of the shaft 412, and the baffle 417 is inserted into the slot 416 opened on the surface of the chuck 415, the baffle 417 will rotate with the shaft 412, which reduces the flow range in the pipe, thereby reducing the speed of water flow and impurities, preventing damage to the filter screen 515. Slow-moving impurities will accumulate in the maintenance pipe 7, and the impurities can be cleaned periodically by rotating the inspection cover 8 that is threadedly connected to the bottom of the maintenance pipe 7.

[0042] Due to its limited lifespan, the filter screen 515 needs to be replaced and maintained periodically. When replacing or maintaining the filter screen 515, rotate the rotating block 524, lift the handle 512, and remove the filter assembly 51 inserted into the mounting assembly 52. ​​This facilitates the replacement and maintenance of the filter screen 515 and also allows for its cleaning.

[0043] In summary: By monitoring the water flow inside the water supply pipe 1 through the underwater sensor 2, and controlling the water flow speed through the regulating mechanism 4, impurities with high flow speeds are blocked by the baffle plate 417, reducing their flow velocity and preventing damage to the filter screen 515 from impact. The deposited impurities can be cleaned through the filter mechanism 5 and the maintenance pipe 7. The filter mechanism 5 filters impurities, and the insertion between the limiting plate 513 and the limiting frame 526 makes the mechanism more airtight, preventing water leakage. The rotatability of the rotating block 524 facilitates the disassembly and assembly of the filter assembly 51, making it convenient to replace, repair, and clean the filter screen 515, thus improving the convenience and practicality of the device.
