Technical Field

[0001] The present invention relates to the technical field of pipeline water supply and drainage, and in particular to a rainwater pipeline sediment interception and pollution interception device capable of removing floating objects and sediments simultaneously and a rainwater pipeline blockage warning system. Background Art

[0002] A drainage system refers to a system for collecting and transporting wastewater such as sewage and rainwater, and among them, a drainage inspection well is an important part of the drainage system. During the collection and discharge of rainwater, many solid debris on the ground, such as sediment, stones, and leaves, may be carried by the initial rainwater and finally flow into the rainwater pipeline. The accumulation of debris in the pipeline will cause pipeline blockage.

[0003] By adding a debris interception and sedimentation device in the inspection well, the above problems can be effectively solved. However, in the related technology, the proportion of the filtering and pollution interception part in the pipeline cross-section is relatively large, which affects the effective flow cross-section of the drainage pipeline, reduces the pipeline flow velocity, increases the head loss and the possibility of pipeline blockage, and cannot remove floating objects and sediments in the wastewater simultaneously. Summary of the Invention

[0022] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0023] The sedimentation and pollution interception device for rainwater pipelines according to an embodiment of the present invention includes a sedimentation mechanism, a pollution interception mechanism, and a detection mechanism. The sedimentation mechanism includes a sedimentation chamber 1 and a mud baffle 2 inclined towards the incoming water direction. The well body of the rainwater sedimentation well is connected to the rainwater pipeline 8. The sedimentation chamber 1 is located at the bottom of the well body of the rainwater sedimentation well and is lower than the rainwater pipeline 8. The pollution interception mechanism includes a pollution interception basket 3 and a connecting member 4. The pollution interception basket 3 is located inside the well body, and the bottom of the pollution interception basket 3 is lower than the top of the rainwater pipeline 8 to intercept the pollutants in the rainwater pipeline 8. The connecting member 4 connects the pollution interception basket 3 to the sedimentation chamber 1. The detection mechanism includes a sludge level gauge 6 and a displacement sensor 7. The sludge 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 pollution interception basket 3 to detect the displacement of the pollution interception basket 3. The sedimentation mechanism is arranged at the bottom of the rainwater sedimentation well. The sedimentation mechanism is used to settle sludge. The pollution interception mechanism is used to filter out the floating debris in the rainwater pipeline 8. The connecting member 4 connects the pollution interception basket 3 and the sedimentation chamber 1 to form an integral body, which can reduce the up and down displacement change of the pollution interception basket 3 relative to the rainwater pipeline 8 and ensure the filtering effect of the pollution interception basket 3 on the floating debris. The detection mechanism uses the sludge level gauge 6 to monitor the sludge height in the sedimentation chamber 1 in real time for timely silt cleaning, and uses the displacement sensor 7 to detect the small displacement of the pollution interception basket 3 relative to the connecting member 4 to judge whether the quantity of the floating objects intercepted in the pollution interception basket 3 exceeds the standard.

[0024] The pollution interception basket 3 and the connecting member 4 can be fixed by threaded connection, snap connection, etc. The connecting member 4 needs to bear the weight of the pollution interception basket 3 and the water flow impact, and has 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 the inner wall of the rainwater sedimentation well. The sedimentation chamber 1 can be an uncovered cylinder or cuboid in the upper part. The top of the sedimentation chamber 1 is lower than the bottom of the rainwater pipeline 8 for sediment to enter and settle. The material of the sedimentation chamber 1 can be made of stainless steel, plastic or other materials. The material of the mud baffle 2 can be the same as that of the sedimentation chamber 1. The mud baffle 2 can prevent the sediment in the sedimentation chamber 1 from being disturbed by the incoming water in the rainwater pipeline 8 and following the water flow into the rainwater pipeline 8 again, and ensure the sediment collection effect of the sedimentation chamber 1.

[0026] The sedimentation and pollution interception device for the rainwater pipeline 8 according to an embodiment of the present invention has the advantages of small influence on the pipeline flow velocity during pollution interception and simultaneous removal of floating objects and sediments.

[0027] In some embodiments, the top of the sedimentation chamber 1 is 3 - 5 cm lower than the rainwater pipeline 8.

[0028] In some embodiments, it further includes a lifting ring 5. The lifting ring 5 is arranged on the top of the pollution interception basket 3 for installing and removing the pollution interception basket 3.

[0029] Specifically, the shape of the lifting ring 5 can be circular or square. The lifting ring 5 can be fixed to the top of the sewage interception basket 3 by means such as welding, bolt connection or snap connection. The lifting ring 5, in cooperation with a crane, a manual lifting tool, etc., can quickly install the sewage interception basket 3, facilitating removal and installation. The installation position and fixing method of the lifting ring 5 can ensure the stability of the sewage interception basket 3 during installation and removal, preventing damage or deformation of the sewage interception basket 3 caused by improper lifting.

[0030] In some embodiments, a scraper mechanism is further included. The scraper mechanism 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 a stainless steel metal plate, and a polytetrafluoroethylene coating can be applied to the surface of the metal plate to adapt to the sediment and rainwater environment. The linear drive member can be an electric push rod, a cylinder or a hydraulic cylinder, etc. The linear drive member can be fixed to the side wall or the top of the sedimentation chamber 1 to ensure the stable movement of the linear drive member. The linear drive member drives the scraper to make a reciprocating linear motion relative to the mudguard 2. The movement speed of the linear drive member can be adjusted according to the sediment deposition amount and cleaning requirements on the mudguard 2. When there is more sediment deposition, the speed is increased, and when there is less deposition, the speed is decreased, so as to improve the cleaning efficiency and energy-saving effect. And high-efficiency cleaning of the mudguard 2 can shorten the cleaning time and reduce the disturbance of the scraper mechanism to the water flow, ensuring the sedimentation effect of the sedimentation chamber 1. The scraper mechanism can automatically and efficiently clean the sediment and dirt on the surface of the mudguard 2, avoiding the cumbersome and untimely manual cleaning. Through the reciprocating motion of the scraper, the sediment deposited on the mudguard 2 can be scraped into the bottom of the sedimentation chamber 1 in time, reducing the accumulation of sediment on the mudguard 2, thereby improving the service life and mudguard effect of the mudguard 2.

[0032] In some embodiments, the sewage interception basket 3 is a semi-cylinder. The water-facing side of the sewage interception basket 3 has an opening. The surface of the sewage interception basket 3 is uniformly provided with mesh holes to block debris. The surface area of the backwater side of the sewage interception basket 3 is larger than the opening area of the water-facing side of the sewage interception basket 3 to ensure the water output of the backwater side of the sewage interception basket 3.

[0033] Specifically, the semi-cylindrical shape of the sewage interception basket 3 can better collect debris, and the cross-sectional area of ​​the semi-cylinder in the direction of water flow gradually decreases, which can allow rainwater to flow out more smoothly when passing through the sewage interception basket 3, speed up the water flow rate and reduce the resistance of the water flow blocked by debris. At the same time, the backwater side of the sewage interception basket 3 can intercept debris to prevent the debris from being washed back into the rainwater pipe 8 by the water flow and leaving the sewage interception basket 3, thereby avoiding secondary pollution. The semi-cylindrical structure and the larger backwater side surface area of ​​the sewage interception basket 3 make it more stable under the impact of water flow and less prone to displacement or deformation. This helps to improve the reliability and service life of the device and reduce the maintenance cost caused by damage or displacement of the sewage interception basket 3. The semi-cylindrical structure allows debris to be deposited on the backwater side of the sewage interception basket 3. When cleaning, the debris can be directly removed from the opening without disassembling the entire sewage interception basket 3.

[0034] The mesh shape of the interception basket 3 can be circular, square or diamond-shaped, etc. The mesh shape is selected according to the type and size of the debris to be intercepted. For larger debris, circular holes with large apertures can be selected, and for fine particles, square holes or diamond-shaped holes with small apertures can be selected. The interception basket 3 is made of corrosion-resistant materials, such as stainless steel, aluminum alloy or glass fiber reinforced material.

[0035] Optionally, the mesh size of the sewage interception basket 3 may be between 20 and 25 mm. The mesh size of the sewage interception basket 3 within this range can filter a larger volume of debris without being easily blocked, and has little effect on the water flow velocity of the rainwater pipe 8 .

[0036] Optionally, the surface of the sewage interception basket 3 can be sprayed with an anti-corrosion coating to reduce the risk of debris adhesion and corrosion. The anti-corrosion coating can protect the sewage interception basket 3 and prevent debris from cutting the surface of the sewage interception basket 3 and causing corrosion.

[0037] In some embodiments, a second filter screen is provided on the backwater side of the sewage interception basket 3 , the aperture of the second filter screen is smaller than the aperture of the mesh, and the second filter screen moves relative to the sewage interception basket 3 to change the filtering effect of the mesh on the backwater side of the sewage interception basket 3 .

[0038] Specifically, the shape of the second filter can be an arc-shaped filter so as to fit with the backwater side of the sewage interception basket 3. Its size should be slightly smaller than the area of ​​the backwater side of the sewage interception basket 3 to ensure that it can completely cover the mesh area on the backwater side of the sewage interception basket 3 and change the effective filtering particle size on the backwater side. The aperture of the second filter is smaller than the aperture of the mesh of the sewage interception basket 3. The aperture of the second filter can be selected according to the type of debris that needs to be further intercepted. For example, if fine particulate matter or suspended matter needs to be intercepted, the aperture can be designed to be smaller than half of the aperture of the mesh of the sewage interception basket 3 to achieve a finer filtering effect.

[0039] It can be understood that the movement of the second filter screen can be driven manually, electrically or pneumatically. Optionally, guide rails are arranged on the backwater side of the sewage interception basket 3, and the second filter screen moves along the guide rails through sliders or slides and moves relative to the sewage interception basket 3 to complete the adjustment and change of the effective filtration particle size on the backwater side of the sewage interception basket 3.

[0040] Optionally, a rainfall sensor is further included. By receiving the data of the rainfall sensor, the position of the second filter screen is automatically adjusted according to the rainfall intensity. When the rainfall intensity is small, the second filter screen can be kept on the backwater side for fine filtration to intercept more sundries; when the rainfall intensity is large, the second filter screen can move to the top or bottom of the sewage interception basket 3 to increase the aperture of the filter holes on the backwater side of the sewage interception basket 3, so as to improve the drainage capacity and prevent rainwater accumulation.

[0041] It can be understood that the aperture of the second filter screen is smaller than that of the mesh holes of the sewage interception basket 3, which can further intercept fine particulate matters, suspended matters or dissolved impurities, and improve the filtration accuracy of the sundries in the rainwater pipe 8. By changing the position of the second filter screen, the filtration effect on the backwater side of the sewage interception basket 3 can be flexibly adjusted. According to different rainfall intensities, water quality conditions and sewage interception requirements, a suitable filtration mode can be selected to realize the switching between coarse filtration and fine filtration. This adjustable filtration method can better adapt to the complex changes in rainwater quality, ensure effective interception of sundries under different working conditions, reduce the pollution of the rainwater pipe 8, and at the same time ensure the smooth discharge of rainwater. When it is detected that the filter holes of the sewage interception basket 3 are blocked, the filtration path can be changed by moving the second filter screen to restore a certain drainage capacity, and avoid water flow blockage or device failure caused by blockage. The presence of the second filter screen can reduce the time when the mesh holes on the backwater side of the sewage interception basket 3 are directly exposed to the water flow, and reduce the risk of the mesh holes being blocked and corroded by sundries. At the same time, by regularly moving the second filter screen, the impact position of the water flow on the backwater side of the sewage interception basket 3 can be changed, and local areas can be prevented from being damaged due to long-term stress, so as to extend the service life of the sewage interception basket 3. The arrangement of the second filter screen improves the filtration efficiency, extends the service life of the sewage interception basket 3 and is more flexible in filtration and cleaning work.

[0042] In some embodiments, a flow guide plate is arranged on the water inlet side of the sewage interception basket 3, and two flow guide plates form a V-shaped structure to accelerate the water flow speed entering the sewage interception basket 3.

[0043] Specifically, the flow guide plate can be a rectangular plate, a trapezoidal plate or other shapes. The flow guide plate is arranged at the opening of the sewage interception basket 3. The extending direction of the flow guide plate can form a certain angle with the water incoming direction. The flow guide plate is used to ensure the smooth entry of the water flow into the sewage interception basket 3. The flow guide plate can be fixed on the water inlet side of the sewage interception basket 3 by plugging, threaded connection or buckling, etc. The angle of the flow guide plate relative to the water incoming direction can be adjusted, and changing the angle can change the flow rate entering the sewage interception basket 3.

[0044] It is understandable that the angle between the guide plate and the sewage interception basket 3 can be adjusted according to the actual water flow speed and sewage interception requirements. For example, when the rainfall intensity is large, the angle can be increased to allow the water flow to enter the sewage interception basket 3 faster; when the rainfall intensity is small, the angle can be reduced to reduce the impact of the water flow on the sewage interception basket 3.

[0045] Two guide plates are arranged on both sides of the sewage interception basket 3 to form a V-shaped structure. As the water flows, the distance between the two guide plates is shortened, which speeds up the water flow into the sewage interception basket 3, making it easier for debris in the rainwater to be intercepted by the sewage interception basket 3, thereby improving the sewage interception efficiency and reducing the risk of accumulation and blockage of debris at the opening of the sewage interception basket 3.

[0046] In some embodiments, the waste interception basket 3 includes a coarse filtration area adjacent to the upstream side and a fine filtration area adjacent to the downstream side, and the pore size of the mesh in the coarse filtration area is larger than the pore size of the mesh in the fine filtration area.

[0047] Specifically, the sewage interception basket 3 is divided into a coarse filtration area and a fine filtration area to intercept debris of different particle sizes. The mesh of the coarse filtration area can be designed to be round, square or diamond with a larger aperture to intercept larger debris, such as leaves, plastic bags, etc. The mesh of the fine filtration area uses a smaller aperture mesh to intercept fine particles or suspended matter. The larger aperture mesh of the coarse filtration area can reduce the resistance of the water flow when entering the sewage interception basket 3, allowing the water flow to pass through the sewage interception basket 3 more smoothly, thereby improving the drainage efficiency of the entire device. The smaller aperture mesh of the fine filtration area can further filter fine particles to ensure the water quality of the outlet water. The deformation or damage of the sewage interception basket 3 caused by the accumulation of debris can be reduced by zoning filtration. The zoning filtration can ensure the flow performance of the sewage interception basket 3 through the coarse filtration area to avoid the blockage of the fine filtration area affecting the operation of the entire sewage interception basket 3.

[0048] In some embodiments, the angle between the mud guard 2 and the vertical direction of the well body is 30° to 45°.

[0049] Specifically, the mudguard 2 itself 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 mud chamber 1 along the mudguard 2 under the action of gravity of the water flow. The water flow is blocked by the mudguard 2 and cannot flip the mud and sand at the bottom of the mud chamber 1 up and away, which can effectively prevent the mud and sand from entering the rainwater pipe 8, can better withstand the impact force of the water flow, and reduce the shaking and displacement of the mudguard 2 under the action of the water flow.

[0050] In addition, the inclination angle of 30° to 45° makes it easier for the mud and debris on the surface of the fender 2 to be washed away by the water flow or cleaned by the scraper mechanism. When cleaning the fender 2, the scraper mechanism reciprocates along the inclination direction of the fender 2, which more effectively cleans the mud and debris on the surface of the fender 2, reduces the cleaning difficulty and workload, and facilitates the maintenance of the equipment.

[0051] In some embodiments, the bottom of the sewage interception basket 3 is 0.7 to 0.9 times the pipe diameter above the inner bottom of the rainwater pipe 8, and the height of the sewage interception basket 3 is 0.4 to 0.6 times the pipe diameter of the rainwater pipe 8.

[0052] Specifically, the bottom of the sewage interception basket 3 being 0.7 to 0.9 times the pipe diameter above the inner bottom of the rainwater pipe 8 can ensure that the sewage interception basket 3 has enough space to intercept debris from the rainwater pipe 8, while avoiding direct contact between the bottom of the sewage interception basket 3 and the inner bottom of the rainwater pipe 8, reducing the abrasion of the bottom of the sewage interception basket 3 by sediment. The height of the sewage interception basket 3 being 0.4 to 0.6 times the pipe diameter of the rainwater pipe 8 can not only ensure that the sewage interception basket 3 has enough interception area to intercept debris in the rainwater pipe 8, but also not be too high to affect the normal flow of the rainwater pipe 8. The settings of the height and bottom height of the sewage interception basket 3 can reduce the resistance of the water flow when passing through the sewage interception basket 3, making the water flow more smoothly, and can avoid the formation of vortices or backflows of the water flow at the sewage interception basket 3, reducing energy loss.

[0053] According to the rainwater pipe 8 clogging warning system of the embodiments of the present invention, the rainwater pipe 8 clogging warning system includes a rainwater pipe 8 sediment interception and sewage interception device;

[0054] An alarm, the alarm is communicatively connected to the detection mechanism, receives signals from the sludge level meter 6 and the displacement sensor 7 and issues an alarm.

[0055] Specifically, the alarm is used to prompt the staff about the status of the sediment chamber 1 and the sewage interception basket 3, and the sediment chamber 1 and the sewage interception basket 3 can be cleaned in a timely manner. When the sludge level meter 6 monitors that the liquid level in the sediment chamber 1 accumulates to half of the total height of the sediment chamber 1, it will send a signal to the alarm, and the alarm issues a silt cleaning warning. To avoid false signals caused by the floating and uneven deposition of silt due to the flow of rainwater during the rainy season, the alarm will only issue a warning when the sludge level measured by the sludge level meter 6 in the sediment chamber 1 reaches half of the height of the sediment chamber 1 three times continuously. The displacement sensor 7 is placed inside the top of the sewage interception basket 3 and has the function of monitoring the displacement change of the sewage interception basket 3 and transmitting remote data. When the displacement of the displacement sensor 7 exceeds 0.5 cm, it will send a signal to the alarm, and the alarm issues a warning that the floating debris exceeds the standard. To avoid false signals sent by the displacement sensor 7 due to the impact of rainwater flow on the sewage interception basket 3 during the rainy season, the alarm will only issue a warning when the displacement measured by the displacement sensor 7 on the sewage interception basket 3 exceeds 0.5 cm three times continuously.
