Description

Technical Field

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

[0002] Many cities are facing severe challenges in separating rainwater and sewage at the source. In order to solve the problem of rainwater and sewage separation, many areas have built a large number of source civil interception wells. In urban drainage systems, overflows in front of the plant and combined pollution often occur due to excessive sewage discharged into the sewage treatment plant in a short period of time. Interception wells play a vital role in the urban rainwater and sewage separation system. It is a key component of the urban drainage system. Its main purpose is to separate rainwater and sewage. In the rainy season, the interception well can effectively intercept rainwater and quickly guide it into the drainage pipe to ensure that the rainwater is discharged in time, thereby avoiding the occurrence of urban waterlogging. In the dry season, it is responsible for intercepting sewage to prevent sewage from mixing into the rainwater pipe and causing water pollution. By accurately diverting rainwater and sewage, interception wells can not only protect water resources from pollution, but also reduce the cost of sewage treatment. In addition, interception wells can also collect and store rainwater resources, which can be used for flushing in public places, watering greenery, etc., which can not only realize the reuse of water resources, but also help the city's water conservation and environmental protection work.

[0003] However, such interception wells often lack necessary control equipment and cannot regulate the interception flow, which can easily cause a series of problems such as sewage backflow into the rainwater pipe network, low sewage inlet concentration, and sewage overflow. Therefore, it is necessary to set up corresponding interception sewage flow control equipment. Existing interception wells mostly use steel hydraulic flow control gates for flow control, but the existing steel hydraulic flow control gates have the pain points of high vertical installation requirements and the inability of flexible interception devices to adjust the flow.

[0004] Chinese patent document CN109098269A discloses a flow regulator for controlling the discharge flow, the flow regulator includes a flow guide 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 at a preset maximum opening; when the hollow closed structure is affected by buoyancy, the buoyancy adjusts the magnitude relationship between the torque of the hollow closed structure and the gate to change the opening of the gate to achieve regulation and control of the discharge flow. The flow regulator provided by this solution adopts a hydraulic mode, which can only adjust the pipeline flow and cannot intercept the flow, and requires a large installation space.

[0005] Chinese patent document CN216516069U discloses a sewage flow regulating device for an interception well, including a mounting mechanism installed inside the sewage hole of the interception well, and a flow regulating mechanism arranged on the mounting mechanism and used to regulate the sewage flow; the mounting mechanism includes two limit buckles arranged inside the sewage hole and symmetrically with the center of the sewage hole as the midpoint, and a locking column connected to the two limit buckles and used to fix 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 a threaded sleeve with two ends respectively sleeved on the first screw rod. The sewage flow is regulated by rotating the flow regulating mechanism. The flow regulating device provided by this scheme can only regulate the flow but cannot intercept; and the locking column is stuck in the middle of the pipe, which is easy to get caught in the garbage guide, causing the equipment to fail to operate and block the flow cross section.

[0006] Therefore, when adjusting the flow, the traditional gate device usually adopts the method of up and down movement, which not only requires a large installation height space, but also easily gets stuck when encountering plastic bags, small wooden sticks and other garbage, affecting the normal operation of the equipment. In addition, the prior art lacks an accurate flow adjustment mechanism, and it is impossible to monitor and adjust the opening angle of the gate in real time, resulting in inaccurate flow control and affecting water treatment efficiency. The present invention intends to develop an intelligent flow adjustment device and a method for regulating sewage flow that can save installation height and improve flow control accuracy. 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. Its purpose is to reduce the installation height of the flow regulating device, reduce the stagnation phenomenon during the flow regulating process, and improve the accuracy and processing efficiency of the flow regulating device flow regulating, in view of the technical problems existing in the prior art.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] In a first aspect, the present invention provides an intelligent flow regulating device, comprising: a mounting assembly, two support frame assemblies and a flow regulating assembly;

[0010] The mounting assembly comprises a mounting plate, and the mounting plate is provided with a channel fixing hole through which the flow channel passes;

[0011] The two support frame assemblies are used to support the flow regulating assembly and fix the flow regulating assembly on the mounting assembly;

[0012] The flow regulating component includes an arc gate, a driving mechanism and an angle sensor. The arc gate can match the sealing port of the flow channel to achieve sealing. The arc gate is a curved plate with an arc surface. The sealing port of the flow channel has an arc cutting surface. The center of the arc cutting surface coincides with the center of the arc surface of the arc gate, so that when the arc gate rotates, the arc surface of the arc gate is consistent with the arc cutting surface of the flow channel. Gate support members are fixed on both sides of the arc gate away from the flow channel. Pins are provided at one end of the gate support members on both sides away from the arc gate. The pins on both sides are movably connected to the free ends of the two support frame assemblies respectively; the driving mechanism is used to drive the pin to drive the arc gate to rotate around the axis center of the pin to adjust the sealing area between the arc gate and the sealing port of the flow channel to achieve the opening degree adjustment of the flow channel; the angle sensor is fixed on the pin, and the rotation center of the angle sensor and the center of the pin are on the same axis; the rotation angle of the arc gate 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 feeding back the rotation angle of the arc gate through the angle sensor, so as to adjust the flow of the flow passage in real time. The arc gate used in 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 cutting surface, and the center of the arc cutting surface coincides with the center of the circular arc surface of the arc gate, so that when the arc gate rotates, the arc surface of the arc gate is consistent with the arc cutting surface of the flow passage, thereby ensuring the sealing performance.

[0014] In a further improvement, a sealing strip is provided at the sealing port of the flow channel, and the sealing strip is fixed to the sealing port of the flow channel by a sealing strip pressure plate, and the arc gate achieves better sealing by squeezing the compression amount of the sealing strip.

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

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

[0017] It is understood by those skilled in the art that the driving mechanism in the scheme of the present invention can theoretically be replaced by a cylinder or other electric actuator, but both the electric actuator and the cylinder are not suitable for long-term immersion in sewage, and the protection level of the driving mechanism needs to be considered. Therefore, the oil cylinder (hydraulic drive method) is preferably used in the scheme of the present invention, because the oil cylinder has a smoother action, greater thrust, and can be immersed in sewage for a long time without the risk of leakage or corrosion, and can operate normally in water for a long time without considering its protection level.

[0018] In a further improvement, the flow regulating assembly further includes an L-shaped rotating arm, one end of which is fixed to a pin on one side, and the other end of which is movably connected to the piston rod of the oil cylinder. The extension and retraction of the oil cylinder pushes the pin to drive the arc gate to rotate, thereby opening and closing the flow channel opening and closing the flow channel flow rate.

[0019] In a further improvement scheme, each support frame assembly includes two support base plates, a first support arm and a second support arm, one end of the first support arm and the second support arm are respectively fixedly connected to one of the support base plates and fixed to the mounting plate through the support base plates, the second support arm is obliquely connected to the horizontal first support arm, and the other end of the first support arm is a free end, and the free end is provided with a swivel bearing seat, which realizes a movable connection with the pin shaft on the corresponding side through the swivel bearing seat.

[0020] In a further improvement, a bolt fixing hole is provided on the bracket bottom plate of the support frame assembly, and the support frame assembly is fixedly mounted on the mounting plate by bolts, and the two support frame assemblies are arranged parallel and symmetrically. During installation, the parallelism of the two support frame assemblies must be ensured, thereby ensuring smooth cooperation between the arc gate and the arc sealing port of the flow channel.

[0021] In a further improvement, the angle sensor is provided with a sensor housing, and the two sides of the sensor housing are respectively fixedly connected to the pins on the two sides through the angle sensor fixing parts, and the angle sensor can rotate together with the pins. The sensor housing can protect the angle sensor from being damaged by stones and other debris in the water, and can also enhance the waterproof level of the angle sensor.

[0022] In a second aspect, the present invention further provides a method for regulating sewage flow, using the above-mentioned intelligent flow regulating device, and specifically comprising the following steps:

[0023] After receiving the command from the control center, the driving mechanism pushes the pin shaft to drive the arc gate plate to rotate. When the flow rate of the flow channel needs to be increased, the driving mechanism pushes the pin shaft to drive the arc gate plate to reduce the sealing area with the port of the flow channel to open more flow channels; when the flow rate of the flow channel needs to be reduced, the driving mechanism pushes the pin shaft to drive the arc gate plate to increase the sealing area with the port of the flow channel to close more flow channels;

[0024] At the same time, when the arc gate rotates, the angle sensor monitors the angle change in real time and feeds back to the control center; the control center controls the pushing displacement of the drive mechanism in real time to achieve control of the rotation angle of the arc gate, and then controls the opening degree of the flow channel, thereby achieving precise regulation of the flow rate of the flow channel.

[0025] In a further improvement, the driving mechanism is a double-acting oil cylinder. After receiving the command from the control center, the extension and retraction of the piston rod of the oil cylinder is controlled to drive the pin shaft to drive the arc gate to rotate, thereby adjusting the sealing area between the arc gate and the sealing port of the flow channel.

[0026] When the flow rate of the flow channel needs to be increased, the piston rod of the control cylinder is extended, thereby pushing the pin shaft to drive the arc gate plate to increase the sealing area with the sealing port of the flow channel; when the flow rate of the flow channel needs to be reduced, the piston rod of the control cylinder is retracted, thereby pushing the pin shaft to drive the arc gate plate to reduce the sealing area with the sealing port of the flow channel, thereby realizing the control of the opening and closing degree of the flow channel, and then realizing the regulation of the flow rate of the flow channel;

[0027] When the arc gate rotates, the angle sensor monitors the angle change in real time and feeds back to the control center; the control center controls the telescopic displacement of the piston rod of the cylinder in real time to realize the control of the rotation angle of the arc gate, and then controls the opening degree of the flow channel, thereby realizing precise adjustment of the flow rate of the flow channel, and finally realizing the regulation of sewage flow of structures such as sewage interception wells.

[0028] Beneficial effects of the present invention:

[0029] The intelligent flow regulating device provided by the present invention adjusts the flow area of ​​the flow channel by pushing the arc gate plate to rotate, thereby achieving the purpose of flow regulation. Specifically, the intelligent flow regulating device of the present invention adopts a rotating arc gate plate design, which can significantly reduce the installation height requirement; introduces an angle sensor, and uses the angle sensor to feedback the rotation angle of the arc gate plate in real time to accurately calculate the opening degree of the flow channel, so as to achieve accurate real-time regulation of the flow rate, which can improve the efficiency and reliability of the water treatment system; adopts the arc section of the flow channel and the arc sealing surface design of the arc gate plate, which can greatly reduce the probability of the flow regulator being stuck due to garbage such as wooden sticks and plastic bags, effectively reduce the problem of equipment stuck due to garbage accumulation, extend the service life of the equipment, and can better solve the shortcomings of traditional gate devices in installation space and garbage disposal.

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

The intelligent flow regulating device provided by the present invention is installed in an interception well with height restrictions, and the arc gate plate is in rotational motion, which can save the height space required for the up and down motion of the traditional gate.

In order to achieve better sealing, as a preferred embodiment, in this embodiment, the sealing port of the flow channel 4 is provided with a sealing strip 9, and the sealing strip 9 is fixed to the sealing port of the flow channel 4 through a sealing strip pressing plate 8, and the arc gate 301 achieves better sealing by squeezing the compression amount of the sealing strip 8.

[0051] In this embodiment, in order to realize the automatic control and flow regulation of the arc gate, gate support members 302 are fixed on both sides of the arc gate 301 away from the flow channel 4.

The intelligent flow regulating device provided by the present invention is installed in an interception well with height restrictions, and the arc gate plate is in rotational motion, which can save the height space required for the up and down motion of the traditional gate.

[0058] Example 2

[0059] This embodiment provides a method for regulating 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, so as to realize the regulation of the flow of the flow pipe of the sewage interception well. 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 the data and calculating, the control center sends a command to the hydraulic station. After receiving the command 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 gate plate 301 to rotate through the slewing bearing seat 10, such as Figure 1 In the orientation shown in the figure, specifically, the arc gate plate 301 moves in an upward or downward arc shape along the arc sealing port surface of the flow channel 4 to adjust the sealing area between the arc gate plate 301 and the port of the flow channel 4.

[0061] When the liquid level in the sewage intercepting well is low and the flow rate of the flow channel 4 needs to be increased, the piston rod of the control cylinder 7 is extended, thereby pushing the pin shaft 304 to drive the arc gate plate 301 to rotate upward to increase the sealing area with the port of the flow channel 4; when the liquid level in the sewage intercepting well is high and the flow rate of the flow channel 4 needs to be reduced, the piston rod of the control cylinder 7 is retracted, thereby pushing the pin shaft 304 to drive the arc gate plate 301 to rotate downward to reduce the sealing area with the port of the flow channel, thereby realizing the control of the opening and closing degree of the flow channel 4, and then realizing the regulation of the flow rate of the flow channel 4.

[0062] At the same time, when the arc gate 301 rotates, the angle sensor 307 monitors the angle change in real time and feeds 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 control the rotation angle of the arc gate 301, and then controls the opening degree of the flow channel 4, thereby realizing the precise regulation of the flow of the flow channel 4. Finally, the sewage flow of the sewage interception well is regulated.

[0063] The intelligent flow regulating device provided by the present invention is applied to the reconstruction of intercepting wells or the construction of new intercepting wells with limited height installation space. Since the arc gate plate is in rotational motion, it can greatly save the height space required for the up and down movement of the traditional gate plate. In addition, in conjunction with the angle sensor, it can realize real-time adjustment of the flow rate, and the working efficiency and accuracy are relatively high.

[0064] It can be understood by those skilled in the art that the sewage flow control method provided in the embodiment of the present invention can be applied to structures such as pump stations, box culvert ditches, and water inlets and outlets of regulating reservoirs in addition to the sewage interception wells of the present embodiment. The flow regulating device opening can be automatically adjusted according to the liquid level changes of the structure, thereby realizing the flow control. When the liquid level in the structure fluctuates, the collected data is fed back to the control center, which automatically calculates and reacts, issues instructions to the hydraulic station, and the hydraulic drive mechanism drives the arc gate of the intelligent flow regulating device to make corresponding adjustments, thereby controlling the outflow and ensuring the constant water volume.

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