Description

Technical Field

[0001] The present invention relates to the technical field of sewage flow regulation equipment, and particularly to an intelligent flow regulating device and a method for regulating sewage flow, and more particularly to an intelligent flow regulating device and a method for regulating sewage flow applicable to a building with limited height installation space. Background Art

[0002] Many cities are facing severe challenges in source rain and sewage diversion. To solve the problem of rain and sewage diversion, a large number of source civil intercepting wells have been built in many areas. In the urban drainage system, there are often situations where excessive sewage is discharged to the sewage treatment plant in a short period, resulting in pre-factory overflow and combined sewer pollution. The intercepting well plays a crucial role in the urban rain and sewage diversion system. It is a key component of the urban drainage system, and its main purpose is to separate rainwater and sewage. In the rainy season, the intercepting well can effectively intercept rainwater and quickly divert it into the drainage pipeline to ensure the timely drainage of rainwater and avoid urban waterlogging. In the dry season, it is responsible for intercepting sewage to prevent sewage from mixing into the rainwater pipeline and causing water pollution. By accurately diverting rainwater and sewage, the intercepting well can not only protect water resources from pollution but also reduce the cost of sewage treatment. In addition, the intercepting well can collect and store rainwater resources, which can be used for flushing public places, greening irrigation, etc. It can not only realize the reuse of water resources but also contribute to the water conservation and environmental protection work of the city.

[0003] However, such intercepting wells often lack necessary control equipment and cannot regulate the intercepted flow, easily causing a series of problems such as sewage backflow into the rainwater pipe network, low sewage inlet concentration, and sewage overflow. Therefore, corresponding sewage flow regulation equipment needs to be set up. Most of the existing intercepting wells use steel hydraulic flow regulating gates for flow regulation, and the existing steel hydraulic flow regulating gates have pain points such as high requirements for vertical installation and inability to regulate the flow of flexible intercepting devices.

[0004] Chinese Patent Document CN109098269A discloses a flow regulator for outlet flow control. The flow regulator includes a diversion structure, a gate, a main body base, and a hollow closed structure that can float on the water surface, which constitute the main structure of the flow regulator; when the hollow closed structure is not affected by buoyancy, the torque of the hollow closed structure is greater than the torque of the gate, so that the gate is in a preset maximum opening; when the hollow closed structure is affected by buoyancy, the buoyancy adjusts the torque relationship between the hollow closed structure and the gate to change the opening of the gate, thereby realizing the adjustment and control of the outlet flow. The flow regulator provided by this solution adopts a hydraulic mode, can only regulate the pipeline flow and cannot intercept, and requires a large installation space.

[0005] Chinese patent document CN216516069U discloses a sewage flow regulating device for a cut-off well, including an installation mechanism installed inside the sewage hole of the cut-off well, and a flow regulating mechanism arranged on the installation mechanism for regulating the sewage flow; the installation mechanism includes two limit buckles arranged inside the sewage hole and symmetrically centered on the center of the sewage hole, and a locking column connected to the two limit buckles for fixing the limit buckles inside the sewage hole; the locking column includes a first screw rod with one end movably connected to the middle position of the limit buckle, and threaded sleeves respectively sleeved on both ends of the first screw rod. By rotating the angle of the flow regulating mechanism, the regulation of the sewage flow is realized. The flow regulating device provided by this solution can only regulate the flow and cannot intercept the flow; moreover, the locking column is stuck in the middle of the pipeline, which is easy to hang garbage and cause the equipment to malfunction and block the flow cross-section.

[0006] Therefore, when the traditional gate device regulates the flow, since it usually adopts an up-and-down movement method, this not only requires a large installation height space, but also is prone to jamming when encountering garbage such as plastic bags and small wooden sticks, affecting the normal operation of the equipment. In addition, there is a lack of an accurate flow regulation mechanism in the prior art, and the opening angle of the gate cannot be monitored and adjusted in real time, resulting in inaccurate flow control and affecting the water treatment efficiency. The present invention intends to develop an intelligent flow regulating device and a method for regulating sewage flow that can save the installation height and improve the accuracy of flow control. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide an intelligent flow regulating device and a method for regulating sewage flow. The purpose is to reduce the installation height of the flow regulating device, reduce the jamming phenomenon during the flow regulation process, and improve the accuracy and treatment efficiency of the flow regulation of the flow regulating device in view of the technical problems existing in the prior art.

[0008] To solve the above technical problems, the present invention adopts the following technical solutions:

[0009] In the first aspect, the present invention provides an intelligent flow regulating device, including: an installation component, two support frame components, and a flow regulating component;

[0010] The installation component includes an installation plate, and the installation plate is provided with a channel fixing hole through which a flow-through channel passes;

[0011] The two support frame components are used to support the flow regulating component and fix the flow regulating component on the installation component;

[0012] The flow regulating component includes an arc-shaped gate plate, a driving mechanism, and an angle sensor. The arc-shaped gate plate can be matched with the sealing port of the flow passage to achieve sealing. The arc-shaped gate plate is a curved plate with a circular arc surface. The sealing port of the flow passage has an arc-shaped cutting surface, and the center of the arc-shaped cutting surface coincides with the center of the circular arc surface of the arc-shaped gate plate, so that when the arc-shaped gate plate rotates, the distance between the arc-shaped surface of the arc-shaped gate plate and the arc-shaped cutting surface of the flow passage is consistent; on both sides of the side of the arc-shaped gate plate facing away from the flow passage, gate plate support members are fixedly provided. At the ends of the two side gate plate support members away from the arc-shaped gate plate, pin shafts are provided, and the pin shafts on both sides are respectively movably connected to the free ends of the two support frame components; the driving mechanism is used to drive the pin shaft to drive the arc-shaped gate plate to rotate around the axis center of the pin shaft to adjust the sealing area between the arc-shaped gate plate and the sealing port of the flow passage, so as to realize the opening degree adjustment of the flow passage; the angle sensor is fixed on the pin shaft, and the rotation center of the angle sensor and the pin shaft center are on the same axis; the rotation angle of the arc-shaped gate plate is fed back in real time through the angle sensor.

[0013] The intelligent flow regulating device of the present invention can accurately calculate the opening degree of the flow passage by the angle sensor feeding back the rotation angle of the arc-shaped gate plate, so as to realize the real-time adjustment of the flow rate of the flow passage. The arc-shaped gate plate adopted by the intelligent flow regulating device of the present invention is a curved plate with a circular arc surface, and the sealing port of the flow passage has an arc-shaped cutting surface, and the center of the arc-shaped cutting surface coincides with the center of the circular arc surface of the arc-shaped gate plate, so that when the arc-shaped gate plate rotates, the distance between the arc-shaped surface of the arc-shaped gate plate and the arc-shaped cutting surface of the flow passage is consistent, thereby ensuring the sealing performance.

[0014] In a further improvement scheme, a sealing strip is provided at the sealing port of the flow passage. The sealing strip is fixed to the sealing port of the flow passage through a sealing strip pressing plate, and the arc-shaped gate plate realizes better sealing by extruding the compression amount of the sealing strip.

[0015] In a further improvement scheme, the driving mechanism is an oil cylinder. An oil cylinder seat is fixedly provided on the mounting plate, and one end of the rodless cavity of the oil cylinder is fixed to the mounting plate through the oil cylinder seat.

[0016] Specifically, the oil cylinder generally refers to a double-acting oil cylinder, that is, both the rod cavity and the rodless cavity of the oil cylinder can be filled with oil for operation.

[0017] Those skilled in the art can understand that the driving mechanism in the solution of the present invention can theoretically be replaced by a cylinder or other electric actuators, but both the electric actuator and the cylinder are not suitable for being immersed in sewage for a long time, and the protection level of the driving mechanism needs to be considered. Therefore, in the solution of the present invention, an oil cylinder (hydraulic drive mode) is preferably adopted because the oil cylinder operates more smoothly, has a greater thrust, and can be immersed in sewage for a long time without risks such as leakage or corrosion, and can operate normally in water for a long time without considering its protection level.

[0018] In a further improvement scheme, the flow regulating component further includes an L-shaped rotating arm. One end of the L-shaped rotating arm is fixed on the pin shaft on one side, and the other end of the L-shaped rotating arm is movably connected to the piston rod of the oil cylinder. By the extension and retraction of the oil cylinder, the pin shaft is driven to drive the arc-shaped gate to rotate, so as to realize the opening and closing of the flow passage opening and the regulation of the flow rate of the flow passage.

[0019] In a further improvement scheme, each support frame component includes two support frame bottom plates, a first support arm and a second support arm. One ends of the first support arm and the second support arm are respectively fixedly connected to one of the support frame bottom plates and are fixed on the mounting plate through the support frame bottom plates. The second support arm is obliquely connected to the transverse first support arm. The other end of the first support arm is a free end, and a slewing bearing seat is provided at the free end, and the movable connection with the pin shaft on the corresponding side is realized through the slewing bearing seat.

[0020] In a further improvement scheme, bolt fixing holes are provided on the support frame bottom plates of the support frame components, and the support frame components are fixedly installed on the mounting plate through bolts. The two support frame components are arranged in parallel and symmetrically. During installation, the parallelism of the two support frame components should be ensured, so as to ensure the smooth cooperation between the arc-shaped gate and the arc-shaped sealing port of the flow passage.

[0021] In a further improvement scheme, the angle sensor is installed with a sensor housing. The two sides of the sensor housing are respectively fixedly connected to the pin shafts on both sides through angle sensor fixing parts, and the angle sensor can rotate together with the pin shaft. The sensor housing can protect the angle sensor from being damaged by sundries such as stones in the water, and can also enhance the waterproof level of the angle sensor.

[0022] In the second aspect, the present invention also provides a method for regulating the sewage flow rate, which adopts the above intelligent flow regulating device, and specifically includes the following steps:

[0023] After receiving the instruction from the control center, the driving mechanism drives the pin shaft to drive the arc-shaped gate to rotate. When it is necessary to increase the flow rate of the flow passage, the driving mechanism drives the pin shaft to drive the arc-shaped gate to reduce the sealing area with the port of the flow passage to open more flow passages; when it is necessary to reduce the flow rate of the flow passage, the driving mechanism drives the pin shaft to drive the arc-shaped gate to increase the sealing area with the port of the flow passage to close more flow passages;

[0024] At the same time, when the arc-shaped gate rotates, the angle sensor monitors the angle change in real time and feeds it back to the control center; the control center controls the pushing displacement of the driving mechanism in real time to control the rotation angle of the arc-shaped gate, and further controls the opening degree of the flow passage, so as to realize the precise regulation of the flow rate of the flow passage.

[0025] In a further improvement scheme, the driving mechanism is a double-acting oil cylinder. After receiving the instruction from the control center, it controls the extension and retraction of the piston rod of the oil cylinder to push the pin shaft to drive the arc-shaped gate to rotate, and adjusts the sealing area between the arc-shaped gate and the sealing port of the flow-through channel;

[0026] When it is necessary to increase the flow rate of the flow-through channel, the piston rod of the oil cylinder is controlled to extend, so as to push the pin shaft to drive the arc-shaped gate to increase the sealing area with the sealing port of the flow-through channel; when it is necessary to decrease the flow rate of the flow-through channel, the piston rod of the oil cylinder is controlled to retract, so as to push the pin shaft to drive the arc-shaped gate to decrease the sealing area with the sealing port of the flow-through channel, realizing the control of the opening degree of the flow-through channel, and further realizing the regulation of the flow rate of the flow-through channel;

[0027] When the arc-shaped gate rotates, the angle sensor monitors the angle change in real time and feeds it back to the control center; the control center controls the telescopic displacement of the piston rod of the oil cylinder in real time to realize the control of the rotation angle of the arc-shaped gate, and further controls the opening degree of the flow-through channel, so as to realize the precise regulation of the flow rate of the flow-through channel, and finally realize the regulation of the sewage flow rate of structures such as the intercepting well.

[0028] The beneficial effects of the present invention:

[0029] The intelligent flow regulation device provided by the present invention realizes the purpose of flow regulation by pushing the arc-shaped gate to rotate so as to adjust the flow-through area of the flow-through channel. Specifically, the intelligent flow regulation device of the present invention adopts a rotary arc-shaped gate design, which can significantly reduce the installation height requirements; an angle sensor is introduced, and the rotation angle of the arc-shaped gate is fed back in real time through the angle sensor to accurately calculate the opening degree of the flow-through channel, realizing the precise real-time regulation of the flow rate, which can improve the efficiency and reliability of the water treatment system; the arc-shaped section of the flow-through channel and the arc-shaped sealing surface of the arc-shaped gate are designed, which can greatly reduce the probability of the flow regulator being stuck caused by garbage such as wooden sticks and plastic bags, effectively reduce the problem of equipment jamming caused by garbage accumulation, extend the service life of the equipment, and can better solve the deficiencies of traditional gate devices in terms of installation space and garbage treatment.

[0030] The intelligent flow regulation device provided by the present invention has a simple structure, a small installation space, energy conservation and environmental protection, and convenient operation and maintenance. It can well solve the pain points of the existing steel hydraulic flow regulation gate with high vertical installation requirements and the flexible intercepting device unable to regulate the flow.

[0031] The intelligent flow regulation device of the present invention is convenient to install, does not require embedded parts, and can be installed by using chemical bolts. The device is made of SS304, which is durable. The operation and maintenance cost is low, and the operation and maintenance workload is small.

[0032] The intelligent flow regulating device provided by the present invention is applicable to the intake and drainage outlets of interception facilities, pumping stations, box culverts, ditches and storage ponds, and is particularly applicable to the retrofitted or newly built interception wells with limited installation space in height. It can automatically adjust the opening degree of the flow regulating device according to the liquid level change, so as to realize the regulation of flow control. When the intelligent flow regulating device provided by the present invention is installed in an interception well with height limitation, the arc-shaped gate plate rotates, which can save the height space required for the up-and-down movement of the traditional gate.

[0045] Embodiment 1

[0046] As Figures 1-4 shown, the embodiment of the present invention provides an intelligent flow regulating device, including: a mounting assembly 1, two support frame assemblies 2, and a flow regulating assembly 3;

[0047] The installation component 1 includes an installation plate, and the installation plate is provided with channel fixing holes through which the overcurrent channel 4 passes; the overcurrent channel 4 is usually an overcurrent pipeline, and the overcurrent pipeline is fixed in the channel fixing holes of the installation plate by welding. Of course, it can be understood that other fixing methods are also within the protection scope of the present invention. The entire installation component 1 is installed on the installation wall through anchor bolts; for example, when applied to the overcurrent flow control of a cut-off well, the installation component 1 is installed on the wall of the cut-off well through anchor bolts.

[0048] Two support frame components 2 are used to support the flow regulating component 3 and fix the flow regulating component 3 on the installation component 1. In this embodiment, as Figure 3 shown, both of the two support frame components 2 include two support frame bottom plates (the first support frame bottom plate 201 and the second support frame bottom plate 203), a first support arm 204 and a second support arm 202. One end of the first support arm 204 is fixedly connected to the first support frame bottom plate 201, and one end of the second support arm 202 is fixedly connected to the second support frame bottom plate 203. The second support arm 202 is obliquely connected to the horizontal first support arm 204. The other end of the first support arm 204 is a free end, and a slewing bearing seat 10 is fixedly provided at the free end. The slewing bearing seat 10 is provided with a shaft hole, and the pin shaft 304 on the corresponding side is sleeved into the shaft hole of the slewing bearing seat 10 on the corresponding side to realize the movable connection of the pin shaft 304. In this embodiment, the slewing bearing seat 10 is fixed to the free end of the first support arm 204 of the support frame component 2 by bolts. It can be understood that other realizable fixed connection methods are also within the protection scope of the present invention.

[0049] The entire support frame component is fixed on the installation plate through these two support frame bottom plates. In this embodiment, the first support frame bottom plate 201 and the second support frame bottom plate 203 are provided with bolt fixing holes and are installed on the installation plate of the installation component 1 through bolts. As those skilled in the art can understand, other fixed connection methods are also within the protection scope of the present invention. The two support frame components are arranged in parallel and symmetrically. During installation, the parallelism of the two support frame components should be ensured to ensure the smooth cooperation between the arc-shaped gate and the arc-shaped sealing port of the overcurrent channel.

[0050] As Figure 1 and Figure 4As shown in the figure, the flow regulating component 3 in this embodiment includes an arc-shaped gate 301, a driving mechanism, and an angle sensor 307. The arc-shaped gate 301 can be matched with the sealing port of the flow passage 4 to achieve sealing. Specifically, the arc-shaped gate 301 is a curved panel with an arc-shaped surface, and at the same time, the sealing port of the flow passage 4 is cut into an arc shape, that is, the sealing port of the flow passage 4 has an arc-shaped cutting surface. The center of the arc-shaped cutting surface of the flow passage of the flow passage 4 coincides with the rotation center of the arc-shaped surface of the arc-shaped gate 301, so that when the arc-shaped gate 301 rotates, the distance between the arc-shaped surface of the arc-shaped gate 301 and the arc-shaped cutting surface of the flow passage 4 is consistent, thereby ensuring the sealing performance. To achieve better sealing, as a preferred embodiment, in this embodiment, a sealing strip 9 is provided at the sealing port of the flow passage 4. The sealing strip 9 is fixed to the sealing port of the flow passage 4 through a sealing strip pressing plate 8, and the arc-shaped gate 301 realizes better sealing by squeezing the compression amount of the sealing strip 8.

[0051] In this embodiment, in order to realize the automatic control of the flow regulation of the arc-shaped gate, both sides of the side of the arc-shaped gate 301 facing away from the flow passage 4 are fixedly provided with gate support members 302. In this embodiment, the arc-shaped gate 301 is fixed to the gate support member 302 by riveting and welding. As can be understood by those skilled in the art, other fixed connection methods are also within the protection scope of the present invention. At one end of each of the two gate support members 302 away from the arc-shaped gate 301, a pin shaft 304 is provided, and the pin shaft 304 is drivably connected to the driving mechanism. In this embodiment, the pin shaft 304 is fixed to the gate support member 302 by welding. As can be understood by those skilled in the art, other fixed connection methods are also within the protection scope of the present invention.

[0052] More specifically, in this embodiment, the two pin shafts 304 are respectively movably connected to the free ends of the two support frame assemblies 3. Specifically, in this embodiment, the pin shaft 304 is movably connected to the free end of the first support arm 204 in the support frame assembly 3. The flow regulating component 3 in this embodiment further includes an L-shaped rotating arm. One end of the L-shaped rotating arm 303 is fixed to one of the pin shafts 304, and the other end of the L-shaped rotating arm 303 is movably connected to the piston rod of the oil cylinder 7. By the extension and retraction of the oil cylinder 7, the L-shaped rotating arm 303 is pushed to drive the pin shaft 304 to rotate, thereby driving the arc-shaped gate 301 to rotate, realizing the opening and closing of the sealing port of the flow passage 4, and realizing the regulation of the flow rate of the flow passage 4. In this embodiment, the end of the L-shaped rotating arm 303 connected to the pin shaft 304 is fixed by welding. It can be understood that other realizable fixed connection methods are also within the protection scope of the present invention.

[0053] More specifically, as a preferred embodiment, in this embodiment, the driving mechanism uses an oil cylinder 7. The oil cylinder 7 is a double-acting oil cylinder, and oil can enter both the rod chamber and the rodless chamber at both ends. A cylinder seat 6 is fixedly arranged on the mounting plate, and one end of the rodless chamber of the oil cylinder 7 is fixed on the mounting plate through the cylinder seat 6. By controlling the extension and retraction of the piston rod of the oil cylinder, the pin shaft 304 is driven to drive the arc-shaped gate plate 301 to rotate around the axis center of the pin shaft 304, and the sealing area between the arc-shaped gate plate 301 and the sealing port of the flow-through channel 4 is adjusted; the opening degree of the flow-through channel is adjusted.

[0054] The angle sensor 307 in this embodiment is fixed on the pin shaft 304, and the rotation center of the angle sensor 307 is on the same axis as the axis center of the pin shaft 304. The rotation angle of the arc-shaped gate plate 304 is fed back through the angle sensor 307 to accurately calculate the opening degree of the flow-through channel 4, so as to realize the real-time adjustment of the flow rate of the flow-through channel. The angle sensor 307 is equipped with a sensor housing 306. The two sides of the sensor housing 306 are respectively fixedly connected to the pin shafts 304 on both sides through angle sensor fixing parts 305. The fixing methods include but are not limited to welding, and the angle sensor 307 can rotate together with the pin shaft 304. The sensor housing 306 can protect the angle sensor 307 from being damaged by sundries such as stones in water, and can also enhance the waterproof level of the angle sensor.

[0055] The intelligent flow regulating device provided by the embodiment of the present invention adjusts the flow-through area of the flow-through channel by pushing the arc-shaped gate plate to rotate, so as to achieve the purpose of flow regulation. Specifically, the intelligent flow regulating device of the present invention adopts a rotary arc-shaped gate plate design, which can significantly reduce the installation height requirements; an angle sensor is introduced, and the rotation angle of the arc-shaped gate plate is fed back in real time through the angle sensor to accurately calculate the opening degree of the flow-through channel, so as to realize the accurate real-time adjustment of the flow rate, which can improve the efficiency and reliability of the water treatment system; the arc-shaped section of the flow-through channel and the arc-shaped sealing surface of the arc-shaped gate plate are designed, which can greatly reduce the probability of the flow regulator being stuck caused by garbage such as wooden sticks and plastic bags, effectively reduce the equipment jamming problem caused by garbage accumulation, extend the service life of the equipment, and can better solve the deficiencies of traditional gate devices in terms of installation space and garbage treatment.

[0056] The intelligent flow regulating device provided by the embodiment of the present invention has a simple structure, a small installation space, energy conservation and environmental protection, and is convenient for operation and maintenance. It can well solve the pain points of the existing steel hydraulic flow regulating gate with high requirements for vertical installation and the flexible intercepting device unable to regulate the flow. The main components of the intelligent flow regulating device in this embodiment are all made of SS304, which is strong, durable and corrosion-resistant, and can ensure that the device functions remain unchanged when used in water for a long time. The intelligent flow regulating device of the present invention is simple and convenient to install, without embedded parts, and can be directly installed with chemical bolts. The later operation and maintenance workload of the flow regulating device is small, and only visual inspection is required daily.

[0057] The intelligent flow regulating device provided by the present invention is applicable to the intake and drainage ports of interception facilities, pumping stations, box culverts and ditches, and storage tanks, and is particularly applicable to the reconstructed or newly built intercepting wells with limited installation space in height. It can automatically adjust the opening degree of the flow regulating device according to the liquid level change, so as to realize the regulation of flow control. Installing the intelligent flow regulating device provided by the present invention in the intercepting well with height limitation, the arc-shaped gate plate rotates, which can save the height space required for the up-and-down movement of the traditional gate plate.

[0058] Embodiment 2

[0059] This embodiment provides a method for regulating the sewage flow. Specifically, the intelligent flow regulating device provided in the above Embodiment 1 is installed on the wall of the sewage interception well through the installation component, and the flow of the flow-through pipeline of the sewage interception well can be regulated. The regulation method specifically includes the following steps:

[0060] When the liquid level in the sewage interception well fluctuates, the collected data will be fed back to the control center. After receiving and calculating the data, the control center issues an instruction to the hydraulic station. After receiving the instruction from the control center, the hydraulic station controls the extension and retraction of the piston rod of the oil cylinder 7 (driving mechanism), and drives the pin shaft 304 to drive the arc-shaped gate plate 301 to rotate through the rotary bearing seat 10, as Figure 1 shown in the orientation, specifically, the arc-shaped gate plate 301 moves in an arc upward or downward along the arc-shaped sealing port surface of the flow-through channel 4 to adjust the sealing area between the arc-shaped gate plate 301 and the port of the flow-through channel 4.

[0061] When the liquid level in the sewage interception well is low and the flow of the flow-through channel 4 needs to be increased, the piston rod of the oil cylinder 7 extends, so as to drive the pin shaft 304 to drive the arc-shaped gate plate 301 to rotate upward to increase the sealing area with the port of the flow-through channel 4; when the liquid level in the sewage interception well is high and the flow of the flow-through channel 4 needs to be reduced, the piston rod of the oil cylinder 7 retracts, so as to drive the pin shaft 304 to drive the arc-shaped gate plate 301 to rotate downward to reduce the sealing area with the port of the flow-through channel, realizing the control of the opening degree of the flow-through channel 4, and further realizing the regulation of the flow of the flow-through channel 4.

[0062] At the same time, when the arc-shaped gate plate 301 rotates, the angle sensor 307 monitors the angle change in real time and feeds it back to the control center; the control center controls the telescopic displacement of the piston rod of the oil cylinder 7 in real time to realize the control of the rotation angle of the arc-shaped gate plate 301, and further controls the opening degree of the flow-through channel 4, so as to realize the precise regulation of the flow of the flow-through channel 4. Finally, the regulation of the sewage flow in the sewage interception well is realized.

[0063] Apply the intelligent flow regulating device provided by the present invention to the reconstructed or newly built intercepting well with limited height installation space. Since the arc-shaped gate plate rotates, it can greatly save the height space required for the up-and-down movement of the traditional gate plate. Moreover, in cooperation with the angle sensor, it can realize the real-time adjustment of the flow rate, with high working efficiency and accuracy.

[0064] Those skilled in the art can understand that the method for regulating the sewage flow rate provided by the embodiments of the present invention can be applied not only to the intercepting well in this embodiment, but also to structures such as pump stations, box culverts and ditches, and the water inlet and outlet of storage ponds. According to the liquid level change of the structure, the opening of the flow regulating device can be automatically adjusted, thereby realizing the regulation of flow control. When the liquid level in the structure fluctuates, the collected data is fed back to the control center. The control center automatically calculates and responds, issues an instruction to the hydraulic station, and the hydraulic drive mechanism drives the arc-shaped gate plate of the intelligent flow regulating device to make corresponding adjustments to control the outflow and ensure the constancy of the water volume.

[0065] The above are only some preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
