Background Technology
[0002] A drainage system is a system used to collect and transport wastewater such as sewage and rainwater, and drainage inspection wells are an important component of the drainage system. During the collection and discharge of rainwater, many solid debris on the ground, such as mud, sand, stones, and leaves, may be carried away by the initial rainwater and eventually flow into the rainwater pipes. The accumulation of debris in the pipes can cause blockages.

[0022] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0023] According to an embodiment of the present invention, the rainwater pipe sedimentation and interception device includes a sedimentation mechanism, an interception mechanism, and a detection mechanism. The sedimentation mechanism includes a sedimentation chamber 1 and a baffle plate 2 inclined towards the direction of incoming water. The well body of the rainwater sedimentation well is connected to the rainwater pipe 8. The sedimentation chamber 1 is located at the bottom of the well body and is lower than the rainwater pipe 8. The interception mechanism includes an interception basket 3 and a connector 4. The interception basket 3 is located inside the well body and its bottom is lower than the top of the rainwater pipe 8 to intercept dirt in the rainwater pipe 8. The connector 4 connects the interception basket 3 to the sedimentation chamber 1. The detection mechanism includes a mud level gauge 6 and a displacement sensor 7. The mud level gauge 6 is used to detect the liquid level height of the sedimentation chamber 1, and the displacement sensor 7 is arranged on the interception basket 3 to detect the displacement of the interception basket 3. The sedimentation mechanism is located at the bottom of the rainwater sedimentation well. The sedimentation mechanism is used to settle sludge, and the interception mechanism is used to filter out floating debris in the rainwater pipe 8. The connector 4 connects the interception basket 3 and the sedimentation chamber 1 to form a whole, which can reduce the vertical displacement of the interception basket 3 relative to the rainwater pipe 8 and ensure the filtering effect of the interception basket 3 on floating debris. The detection mechanism uses the mud level gauge 6 to monitor the sludge height in the sedimentation chamber 1 in real time so as to clean the sludge in time. The displacement sensor 7 detects the slight displacement of the interception basket 3 relative to the connector 4 to determine whether the number of floating objects intercepted in the interception basket 3 exceeds the standard.
[0024] The intercepting basket 3 and the connecting piece 4 can be fixed by threaded connection, snap-fit connection, etc. The connecting piece 4 needs to bear the weight of the intercepting basket 3 and the impact of water flow, and has a certain strength and corrosion resistance. It can be made of materials such as stainless steel and aluminum alloy.
[0025] The sedimentation chamber 1 can be a structure that fits into the inner wall of the rainwater sedimentation well. The sedimentation chamber 1 can be a cylinder or cuboid without an upper cover. The top of the sedimentation chamber 1 is lower than the bottom of the rainwater pipe 8 to allow sediment to enter and settle. The sedimentation chamber 1 can be made of stainless steel, plastic, or other materials. The mudguard 2 can be made of the same material as the sedimentation chamber 1. The mudguard 2 prevents the sediment in the sedimentation chamber 1 from being disturbed by the water flow from the rainwater pipe 8 and re-entering the rainwater pipe 8, ensuring the effective sediment collection of the sedimentation chamber 1.
[0026] The rainwater pipe sedimentation and interception device according to the present utility model has the advantages of having little impact on the pipe flow rate during interception and removing both floating objects and sediments.
[0027] In some embodiments, the top of the sedimentation chamber 1 is 83-5 cm below the rainwater pipe.
[0028] In some embodiments, a lifting ring 5 is also included, which is arranged on top of the sludge basket 3 for installing and removing the sludge basket 3.
[0029] Specifically, the lifting ring 5 can be circular or square. The lifting ring 5 can be fixed to the top of the intercepting basket 3 by welding, bolting, or snap-fit connections. The lifting ring 5, in conjunction with a crane or manual lifting tools, allows for quick installation of the intercepting basket 3, facilitating easy removal and installation. The installation position and fixing method of the lifting ring 5 ensure the stability of the intercepting basket 3 during installation and removal, preventing damage or deformation due to improper lifting.
[0030] In some embodiments, a scraper mechanism is also included, which includes a linear drive member and a scraper. The scraper reciprocates along the inclined surface of the mudguard 2 under the drive of the linear drive member to clean the surface of the mudguard 2.
[0031] Specifically, the lower edge of the scraper of the scraper mechanism is in contact with the upper surface of the mudguard 2. Optionally, the scraper is made of wear-resistant and corrosion-resistant materials, such as stainless steel. The surface of the metal plate can be coated with polytetrafluoroethylene (PTFE) to adapt to mud and rainwater environments. The linear drive component can be an electric push rod, a cylinder, or a hydraulic cylinder, etc. The linear drive component can be fixed to the side wall or top of the sedimentation chamber 1 to ensure stable movement. The linear drive component drives the scraper to reciprocate linearly relative to the mudguard 2. The movement speed of the linear drive component can be adjusted according to the amount of mud and sand deposited on the mudguard 2 and the cleaning requirements. The speed is increased when there is more mud and sand deposited and decreased when there is less deposited, to improve cleaning efficiency and energy saving. Furthermore, efficient cleaning of the mudguard 2 can shorten cleaning time and reduce the disturbance of the water flow by the scraper mechanism, ensuring the sedimentation effect of the sedimentation chamber 1. The scraper mechanism can automatically and efficiently clean the mud and dirt on the surface of the mudguard 2, avoiding the tediousness and untimely nature of manual cleaning. The reciprocating motion of the scraper can promptly scrape the mud and sand deposited on the mudguard 2 into the bottom of the sedimentation chamber 1, reducing the accumulation of mud and sand on the mudguard 2, thereby improving the service life and mud-blocking effect of the mudguard 2.
[0032] In some embodiments, the intercepting basket 3 is a semi-cylinder, with an opening on the water-facing side. The surface of the intercepting basket 3 is uniformly provided with mesh holes to block debris. The surface area of the back side of the intercepting basket 3 is larger than the opening area on the water-facing side to ensure the water output on the back side of the intercepting basket 3.
[0033] Specifically, the semi-cylindrical shape of the interceptor basket 3 better collects debris. The cross-sectional area of the semi-cylinder gradually decreases in the direction of water flow, allowing rainwater to flow out more smoothly and accelerating the water flow, reducing the resistance caused by debris. Simultaneously, the backwater side of the interceptor basket 3 traps debris, preventing it from being washed back into the rainwater pipe 8 and detaching from the basket, thus avoiding secondary pollution. The semi-cylindrical structure and large backwater surface area of the interceptor basket 3 make it more stable under water flow impact, less prone to displacement or deformation. This helps improve the reliability and service life of the device, reducing maintenance costs caused by damage or displacement of the interceptor basket 3. The semi-cylindrical structure allows debris to settle on the backwater side of the interceptor basket 3, enabling direct removal of debris from the opening during cleaning without disassembling the entire basket 3.
[0034] The mesh shape of the intercepting basket 3 can be circular, square, or diamond-shaped, depending on the type and size of the debris being intercepted. Larger debris can be intercepted with large-diameter circular holes, while smaller particles can be intercepted with small-diameter square or diamond-shaped holes. The intercepting basket 3 is made of corrosion-resistant materials, such as stainless steel, aluminum alloy, or fiberglass reinforced materials.
[0035] Optionally, the mesh size of the intercepting basket 3 can be between 20 and 25 mm. Within this range, the mesh size of the intercepting basket 3 can filter larger debris without easily clogging it, and has little impact on the water flow velocity of the rainwater pipe 8.
[0036] Optionally, the surface of the sludge basket 3 can be coated with an anti-corrosion coating to reduce the risk of debris adhesion and corrosion. The anti-corrosion coating can protect the sludge basket 3 and prevent debris from cutting the surface of the sludge basket 3 and causing corrosion.
[0037] In some embodiments, a second filter screen is provided on the back side of the trap basket 3. The pore size of the second filter screen is smaller than that of the mesh. The second filter screen is moved relative to the trap basket 3 to change the filtration effect of the mesh on the back side of the trap basket 3.
[0038] Specifically, the second filter screen can be an arc-shaped screen to fit against the back water side of the trap basket 3. Its size should be slightly smaller than the area of the back water side of the trap basket 3 to ensure complete coverage of the mesh area on the back water side of the trap basket 3, thereby changing the effective filter particle size on the back water side. The pore size of the second filter screen is smaller than the pore size of the mesh of the trap basket 3. The pore size of the second filter screen can be selected according to the type of debris that needs to be further intercepted. For example, if it is necessary to intercept fine particles or suspended matter, the pore size can be designed to be less than half the pore size of the mesh of the trap basket 3 to achieve a finer filtration effect.
[0039] Understandably, the movement of the second filter screen can be manually adjusted, electrically driven, or pneumatically driven. Optionally, a guide rail is arranged on the backwater side of the trap basket 3, and the second filter screen moves along the guide rail and relative to the trap basket 3 by sliding or dropping, thereby adjusting and changing the effective filter particle size on the backwater side of the trap basket 3.
[0040] Optionally, a rainfall sensor is also included, which receives data from the rainfall sensor and automatically adjusts the position of the second filter screen according to the rainfall intensity. When the rainfall intensity is low, the second filter screen can remain on the back side for fine filtration to intercept more debris; when the rainfall intensity is high, the second filter screen can be moved to the top or bottom of the intercepting basket 3, increasing the pore size of the filter holes on the back side of the intercepting basket 3 to improve drainage capacity and prevent rainwater accumulation.
[0041] Understandably, the second filter screen has a smaller pore size than the trap basket 3, enabling it to further intercept fine particles, suspended solids, or dissolved impurities, thus improving the filtration accuracy of debris within the rainwater pipe 8. By changing the position of the second filter screen, the filtration effect on the back side of the trap basket 3 can be flexibly adjusted. Based on different rainfall intensities, water quality conditions, and interception requirements, a suitable filtration mode can be selected, allowing for switching between coarse and fine filtration. This adjustable filtration method better adapts to complex changes in rainwater quality, ensuring effective interception of debris under various operating conditions, reducing pollution to the rainwater pipe 8, and guaranteeing smooth rainwater drainage. When blockage is detected in the trap basket 3's filter holes, moving the second filter screen can alter the filtration path, restoring some drainage capacity and preventing water flow obstruction or device malfunction due to blockage. The presence of the second filter screen reduces the time the back side of the trap basket 3's mesh is directly exposed to water flow, lowering the risk of mesh blockage and corrosion. Meanwhile, by periodically moving the second filter screen, the impact position of the water flow on the back side of the trap basket 3 can be changed, preventing damage to localized areas due to long-term stress and thus extending the service life of the trap basket 3. The arrangement of the second filter screen improves filtration efficiency, extends the service life of the trap basket 3, and allows for more flexible filtration and cleaning.
[0042] In some embodiments, a guide plate is provided on the water-facing side of the intercepting basket 3, and the two guide plates form a V-shaped structure to accelerate the water flow into the intercepting basket 3.
[0043] Specifically, the guide plate can be a rectangular plate, a trapezoidal plate, or other shapes. The guide plate is arranged at the opening of the intercepting basket 3, and the extension direction of the guide plate can have a certain angle with the direction of incoming water. The guide plate is used to ensure that the water flows smoothly into the intercepting basket 3. The guide plate can be fixed to the water-facing side of the intercepting basket 3 by means of plug-in connection, threaded connection, or snap-fit. The angle of the guide plate relative to the direction of incoming water can be adjusted, and changing the angle can change the flow rate entering the intercepting basket 3.
[0044] Understandably, the angle between the baffle plate and the intercepting basket 3 can be adjusted according to the actual water flow velocity and interception requirements. For example, when the rainfall intensity is high, the angle can be increased to allow the water to enter the intercepting basket 3 more quickly; when the rainfall intensity is low, the angle can be decreased to reduce the impact of the water flow on the intercepting basket 3.
[0045] Two guide plates are arranged on both sides of the intercepting basket 3, forming a V-shaped structure. As the water flows, the distance between the two guide plates shortens, which speeds up the water flow into the intercepting basket 3, making it easier for debris in the rainwater to be intercepted by the intercepting basket 3, improving the interception efficiency, and reducing the risk of debris accumulation and blockage at the opening of the intercepting basket 3.
[0046] In some embodiments, the trap 3 includes a coarse filtration zone adjacent to the water-facing side and a fine filtration zone adjacent to the water-returning side, wherein the pore size of the coarse filtration zone is larger than that of the fine filtration zone.
[0047] Specifically, the intercepting basket 3 is divided into a coarse filtration zone and a fine filtration zone to intercept debris of different particle sizes. The mesh of the coarse filtration zone can be designed with larger apertures (circular, square, or rhomboid) to intercept larger debris, such as leaves and plastic bags. The mesh of the fine filtration zone uses smaller apertures to intercept fine particles or suspended solids. The larger aperture mesh of the coarse filtration zone reduces water resistance when entering the intercepting basket 3, allowing water to flow more smoothly and improving the overall drainage efficiency of the device. The smaller aperture mesh of the fine filtration zone further filters fine particles, ensuring the quality of the effluent. This zoned filtration reduces the accumulation of debris that could deform or damage the intercepting basket 3. The coarse filtration zone ensures the flow performance of the intercepting basket 3, preventing blockage in the fine filtration zone from affecting the overall operation of the intercepting basket 3.
[0048] In some embodiments, the angle between the mudguard 2 and the vertical direction of the well body is 30° to 45°.
[0049] Specifically, the mudguard 2 is a flat mudguard 2. When the inclination angle of the mudguard 2 is 30° to 45°, the mud and sand can smoothly slide into the bottom of the sedimentation chamber 1 under the gravity of the water flow. The water flow is blocked by the mudguard 2 and cannot turn the mud and sand at the bottom of the sedimentation chamber 1 up and get off. It can effectively prevent the mud and sand from entering the rainwater pipe 8, and can better withstand the impact of the water flow, reducing the shaking and displacement of the mudguard 2 under the action of the water flow.
[0050] The additional 30° to 45° tilt angle makes it easier for mud and debris on the surface of mudguard 2 to be washed away by the water flow or cleaned by the scraper mechanism. When cleaning mudguard 2, the scraper mechanism reciprocates along the tilt direction of mudguard 2, which more effectively cleans mud and debris on the surface of mudguard 2, reduces cleaning difficulty and workload, and facilitates equipment maintenance.
[0051] In some embodiments, the bottom of the intercepting basket 3 is 0.7 to 0.9 times the diameter of the inner bottom of the rainwater pipe 8, and the height of the intercepting basket 3 is 0.4 to 0.6 times the diameter of the rainwater pipe 8.
[0052] Specifically, the bottom of the intercepting basket 3 is 0.7 to 0.9 times the pipe diameter higher than the inner bottom of the rainwater pipe 8. This ensures that the intercepting basket 3 has sufficient space to intercept debris from the rainwater pipe 8, while avoiding direct contact between the bottom of the intercepting basket 3 and the inner bottom of the rainwater pipe 8, reducing wear and tear on the bottom of the intercepting basket 3 caused by silt. The height of the intercepting basket 3 is 0.4 to 0.6 times the pipe diameter of the rainwater pipe 8, ensuring that the intercepting basket 3 has sufficient interception area to intercept debris from the rainwater pipe 8, without being too high and affecting the normal flow of rainwater in the pipe 8. The height and bottom height settings of the intercepting basket 3 reduce the resistance of water flow when passing through it, allowing for smoother water flow and preventing the formation of eddies or backflows at the intercepting basket 3, thus reducing energy loss.
[0053] According to the embodiment of the present utility model, the rainwater pipe 8 siltation early warning system includes a rainwater pipe 8 sedimentation and interception device.
[0054] An alarm is communicatively connected to the detection mechanism, receives signals from the mud level gauge 6 and the displacement sensor 7, and issues an alarm.
[0055] Specifically, the alarm is used to alert staff to the status of the sedimentation chamber 1 and the intercepting basket 3, allowing for timely cleaning of these structures. When the sludge level gauge 6 detects that the liquid level in the sedimentation chamber 1 has accumulated to half its total height, it sends a signal to the alarm, which then issues a sludge removal warning. To prevent rainwater flow during the rainy season from causing sludge to float and accumulate unevenly, the sludge level gauge 6 sends an error signal. The alarm will only sound when the sludge level gauge 6 measures the sludge level in the sedimentation chamber 1 for three consecutive times and all measurements show the sludge level at half its height. The displacement sensor 7 is located on the top inner side of the intercepting basket 3 and has the function of monitoring the displacement changes of the intercepting basket 3 and transmitting data remotely. When the displacement of the displacement sensor 7 exceeds 0.5 cm, it sends a signal to the alarm, which then issues a floating debris exceeding the limit warning. To prevent rainwater flow during the rainy season from impacting the intercepting basket 3, the displacement sensor 7 sends an error signal. The alarm will only sound when the displacement of the displacement sensor 7 on the intercepting basket 3 measures the displacement for three consecutive times and all measurements show the displacement exceeds 0.5 cm.
