The lower part of the first annular cavity is connected to the second collecting trough 42, and the upper part of the first annular cavity is connected to the first accommodating cavity 121.

[0065] In this embodiment, the body 1 is the main structure of the manhole cover, including a cover plate 11 and a cylinder shell 12, and the cylinder shell 12 is arranged in the vertical direction to form a passage for accommodating water flow and sediment. Among them, the cover plate 11 can be understood as the upper covering structure of the manhole cover, and the cylinder shell 12 can be a cylindrical structure formed by casting, and the cover plate 11 is installed above the cylinder shell 12. For the convenience of description, the structure of the cylinder shell 12 is divided into a first opening, a second opening and a first accommodating chamber 121, wherein the first opening and the second opening are the opening diameters at both ends of the cylinder shell 12 when it is placed in the vertical direction, and the first accommodating chamber 121 is also the internal structure of the cylinder shell 12; the first opening is the upper opening of the cylinder shell 12, and the second opening is the lower opening of the cylinder shell 12, and the cover plate 11 is arranged at the first opening; the second opening is a side opening connected to the sewer.

[0066] The guide ring group 2 is a guide assembly arranged inside the cylinder shell 12. The guide ring group 2 may include multiple guide rings. The setting position of each guide ring is different. For the convenience of distinction, the multiple guide rings in the guide ring group 2 are divided into a first guide ring 21, a second guide ring 22, and a third guide ring 23 described later. Among them, the first guide ring 21 is arranged at the first opening, and the first guide ring 21 is arranged below the cover plate 11. The first guide ring 21 can guide the water flow flowing into the cover plate 11. In this embodiment, the first guide ring 21 has a first guide port. The water flow is driven by the first guide ring 21 to converge to the first guide port and flows downward under the action of gravitational potential energy. The second guide ring 22 is arranged between the first opening and the second opening. Optionally, the second guide ring 22 can be arranged in the middle of the first accommodating cavity 121, or in an upper position of the middle of the first accommodating cavity 121. The second guide ring 22 and the first guide ring 21 can be the same size. The second guide ring 22 can perform secondary diversion on the water flowing into the first guide port, and the second guide ring 22 can also be used to guide the water seeping out of the first collecting groove 41, so that the water flows from the second guide port into the second collecting groove 42.

[0067] In this embodiment, the diversion component 3 is arranged between the first guide port and the second guide port, and the diversion component 3 includes a conical filter plate 31. Specifically, the conical filter plate 31 is a filtering structure with a conical structure. The conical tip of the conical filter plate 31 is arranged to face upward, and the conical edge extends downward. The conical filter plate 31 is arranged below the first guide port. A plurality of water seepage filter holes are provided on the conical filter plate 31 to facilitate the infiltration of water flow and silt smaller than the filter holes, so as to enter the second guide port below and finally flow into the second collecting tank 42; and impurities, stones, and silt larger than the conical filter plate 31 can flow into the first collecting tank 41 under the guidance of the conical surface, thereby realizing the filtering of large particle impurities on the conical filter plate 31.

[0068] Optionally, holes for water seepage may be provided at the bottom of the first collection tank 41, so that the residual water flow can seep from the first collection tank 41 into the position of the second guide ring 22 below, and finally converge at the second guide port. In this embodiment, the first collection tank 41 is a ring-shaped tank structure, and the first collection tank 41 is arranged at the outer edge of the conical filter plate 31, so as to guide the large particles of impurities on the conical filter plate 31. Optionally, the second collection tank 42 may be a cylindrical structure, and the second collection tank 42 is arranged below the second guide port, and the water flow will enter the second collection tank 42 under the action of gravity after passing through the second guide port.

[0069] Furthermore, an oblique tube filter group 6 is provided in the circumferential direction of the second collecting tank 42. The oblique tube filter group 6 includes a first side wall 61, a second side wall 62 and a plurality of first partitions. The first side wall 61 is a truncated cone side wall structure, and the second side wall 62 is also a truncated cone side wall structure. Specifically, the first side wall 61 and the second side wall 62 are both inverted truncated cone side wall structures. The diameter of the first side wall 61 is greater than that of the second side wall 62. When the first side wall 61 and the second side wall 62 are coaxially arranged, the first side wall 61 and the second side wall 62 form a first annular cavity. A plurality of first partitions are provided in the first annular cavity. The first partitions divide the first annular cavity into a plurality of channels. The lower portion of the first annular cavity is connected to the second collecting tank 42, and the upper portion of the first annular cavity is connected to the first accommodating chamber 121. Please refer to Figure 5 and Figure 6 , Figure 5 , Figure 6 The arrows in the figure indicate the direction of water flow. Figure 6 The up and down arrows in the figure indicate the up and down movement of the diversion component and the sensor component. When in use, the water flows into the second collection tank 42 from the second diversion port, the bottom of the second collection tank 42 is in a blocked state, and the sediment will be deposited in the second collection tank 42 under the action of gravity, and the water flows out from the bottom to the top through the first annular cavity and re-enters the first accommodating chamber 121, and flows into the second opening below the first accommodating chamber 121 under the action of gravity, thereby realizing the secondary filtration of sediment, collecting large particles of impurities in the first collection tank 41, and collecting small particles of impurities in the second collection tank 42, thereby reducing the risk of impurities in the water flow blocking the sewer.

[0070] It should be noted that the first preset gradient and the second preset gradient represent the inclination trends of the slopes of the first side wall 61 and the second side wall 62, respectively, and the specific values ​​can be set according to actual needs. When the first preset gradient is the same as the second preset gradient, the upper opening of the first annular cavity is the same size as the lower opening, that is, the openings at both ends of the channel separated by the first partition are the same; when the first preset gradient is different from the second preset gradient, the upper opening of the first annular cavity and the lower opening will have different calibers, which may present an opening caliber distribution of small at the top and large at the bottom, or large at the top and small at the bottom, preferably a large at the top and small at the bottom. This method allows less sediment to pass through the lower opening of the first annular cavity. At the same time, based on the Bernoulli principle, when the water flows into the first annular cavity from the lower opening of the first annular cavity, the flow rate will be increased, thereby facilitating the water flow to flow out from the upper opening of the first annular cavity.

[0071] Furthermore, the present embodiment is also provided with a sensor assembly 5, which is arranged below the diverter assembly 3, and the sensor assembly 5 is arranged above the second collection tank 42. The sensor assembly 5 includes a first sensor 51, a first drive unit 52, a control unit 53 and a first support plate 54, wherein the first sensor 51 is a sediment detection sensor, which can be a photoelectric sensor, an ultrasonic sensor, a conductivity sensor, etc., the first sensor 51 is placed in the second collection tank 42, and the first drive unit 52 can be a servo motor. The first support plate 54 is connected to the first drive unit 52 by transmission, which can be a screw connection, a gear rack connection, etc., and the first support plate 54 is arranged above the second collection tank 42. Preferably, the first support plate 54 can just block the opening above the second collection tank 42. Specifically, the first support plate 54 is connected to the first drive unit 52 by transmission so that the first support plate 54 can move relative to the cylinder shell 12. For example, the first support plate 54 is connected to the cylinder shell 12 through a rack transmission, and a first driving unit 52 is provided on the first support plate 54. A gear is provided at the output end of the first driving unit 52. When the first driving unit 52 drives the gear to rotate, the meshing relationship between the gear and the rack causes the gear to move relative to the rack, thereby driving the first support plate 54 to move relative to the cylinder shell 12; for another example, the first support plate 54 is connected to the cylinder shell 12 through a screw and a screw nut, and the first driving unit 52 is connected to the screw. When the first driving unit 52 drives the screw to rotate, the screw nut is driven to rotate, thereby realizing the movement of the first support plate 54 relative to the cylinder shell 12.

[0072] The control unit 53 can be a microcomputer chip, such as an MCU. The control unit 53 is electrically connected to the first sensor 51 and the first drive unit 52, respectively. When the first sensor 51 senses that the sediment in the second collection tank 42 is about to overflow the second collection tank 42, the control unit 53 controls the first drive unit 52 to drive the first support plate 54 to move downward until the first support plate 54 is blocked above the second collection tank 42, thereby preventing the continuous entry of sediment. At the same time, since the diverter assembly 3 is arranged above the sensor assembly 5, when the first drive unit 52 drives the sensor assembly 5 to move downward, the diverter assembly 3 will also move downward synchronously, and a vertical height difference is formed between the conical filter plate 31 and the first collection tank 41. This height difference forms a gap between the conical filter plate 31 and the first collection tank 41, and the water flow can enter the second guide port from this gap, thereby expanding the water flow rate and adapting to the scene of large water flow.

[0073] In some preferred embodiments, the control unit 53 can generate the output power of the first driving unit 52 based on the sediment deposition data sensed by the first sensor 51, thereby realizing dynamic adjustment of the sensor component 5 and the diversion component 3 in the vertical direction, and reasonably adjusting the water flow rate to avoid the problem of water accumulation inside the manhole cover caused by excessive water flow.

[0074] When rainwater or other liquid flows into the manhole cover, the water flows through the cover plate 11 and enters the first opening of the shell 12. When the water flows through the first guide ring 21, a certain flow rate and vortex effect are formed, which helps to initially separate larger sediment particles. The larger sediment settles into the first collection tank 41 by gravity. The water continues to flow to the second guide ring 22, further controlling the water flow speed, forming a stronger vortex effect, and promoting the sedimentation of fine sediment, and the sediment enters the second collection tank 42. The conical filter plate 31 in the diversion assembly 3 is used to filter large particles of sediment to ensure that cleaner water flows into the next process. The first sensor 51 detects the sediment content in the second collection tank 42 in real time, and the control unit 53 drives the movement of the first support plate 54 according to the detection result, adjusts the direction of the water flow, and optimizes the separation effect of the sediment. When the water flows through the second collection tank 42, the water flow is guided by the inclined tube filter group 6, and the sediment is blocked at the same time, so that the sediment remains in the second collection tank 42.

[0075] In some embodiments, a handle that can be pulled can be provided inside the shell 12, and a handle that can be pulled can be provided on the cover plate 11, so as to facilitate replacement, removal or maintenance of the manhole cover. In other optional embodiments, a snap fastener can be provided at the connection between the cover plate 11 and the shell 12 to facilitate the removal of the cover plate 11 and the shell 12.

[0076] This embodiment significantly improves the separation efficiency of sediment and maintains the water quality through the multi-stage guide ring design and the diversion component 3. The sensor component 5 is used to monitor the sediment content in real time, automatically adjust the water flow, optimize the separation effect, and reduce the need for manual intervention. Effectively separate sediment, reduce the risk of blockage in the drainage system, and reduce subsequent maintenance and cleaning costs. The manhole cover is suitable for a variety of environments and climatic conditions, and can be widely used in urban drainage, rainwater collection and other occasions.

[0077] See also Figures 4 to 6 In some embodiments, the diversion assembly 3 also includes a first support shaft 32, the first support shaft 32 is rotatably connected to the cartridge shell 12, and the conical filter plate 31 is connected to the first support shaft 32; the sensor assembly 5 also includes a first shield 55, the first shield 55 is arranged on the first support plate 54, the first support shaft 32 is arranged above the first shield 55, and a second accommodating chamber is formed between the first shield 55 and the first support plate 54; the second support shaft 56 is connected to the cartridge shell 12, and the second support shaft 56 is slidably connected to the first support plate 54.

[0078] In some embodiments, the first support shaft 32 and the second support shaft 56 are integrally formed.

[0079] In this embodiment, the first support shaft 32 and the second support shaft 56 can be the aforementioned rack structure or screw structure. When the first support shaft 32 is not integrally formed with the second support shaft, the first support shaft 32 can be fixedly connected to the conical filter plate 31 and the first shield 55, such as welding, locking connection, etc., to maintain the positional relationship between the conical filter plate 31 and the first shield 55. The second support shaft 56 connects the cylinder shell 12, the second support groove and the first support plate 54, wherein the second support shaft 56 and the first support plate 54 are in a transmission connection relationship. Optionally, the second support shaft 56 can be set at the center of the second collection groove 42, and then the connecting rod or support beam required for connecting between the second collection groove 42 and the inner side wall of the cylinder shell 12 is set at the bottom of the second collection groove 42 to achieve the position fixation of the second collection groove 42 and the cylinder shell 12.

[0080] In this embodiment, the first shield 55 can be an eggshell structure, or a thin-walled structure of a special shape. The first shield 55 is airtightly connected to the first support plate 54, and the first support plate 54 is also airtightly connected to the second support shaft 56 to prevent the first drive unit 52 and the control unit 53 from being eroded by water flow. A second accommodating chamber is formed between the first shield 55 and the first support plate 54, the first drive unit 52 and the control unit 53 are arranged in the second accommodating chamber, and the first sensor 51 is arranged in the second collection tank 42. It can be understood that there is a gap between the first shield 55 and the inner side wall of the first collection tank 41, so that the water flow infiltrated by the conical filter plate 31 can flow to the second guide port.

[0081] This embodiment adds a connection design between the first support shaft 32 and the conical filter plate 31, so that the conical filter plate 31 can adjust its angle and position as the shaft rotates, thereby better separating and filtering large particles of sediment in the incoming water. The first support shaft 32 and the second support shaft 56 are integrally formed or connected through a rack / screw structure, which enhances the structural stability of the entire diversion assembly 3 and improves durability. A first protective cover 55 is provided to isolate key components such as the first drive unit 52 and the control unit 53 in the second accommodating chamber to avoid direct erosion by the water flow, thereby improving the waterproof performance and reliability of the system. A gap is left between the first protective cover 55 and the first collection tank 41 to ensure that the filtered water flow can flow smoothly to the second diversion port downstream to avoid water flow blockage.

[0082] In some embodiments, the diameter of the first guide ring 21 gradually decreases along the first opening to the second opening at a third preset gradient, and the diameter of the second guide ring 22 gradually decreases along the first opening to the second opening at a fourth preset gradient; the guide ring group 2 also includes a third guide ring 23, the third guide ring 23 is arranged on the inner side of the second guide ring 22, and the diameter of the third guide ring 23 gradually decreases along the first opening to the second opening at a fifth preset gradient, and there is a first guide gap between the second guide ring 22 and the third guide ring 23, the third guide ring 23 has a third guide port, and the third guide port is connected to the second collection tank 42.

[0083] In this embodiment, the third preset gradient and the fourth preset gradient can be understood with reference to the first preset gradient, the third preset gradient represents the diameter change trend of the first guide ring 21, and the fourth preset gradient represents the diameter change trend of the second guide ring 22. The third preset gradient and the fourth preset gradient can be set according to actual needs. Optionally, the third preset gradient and the fourth preset gradient can be the same.

[0084] The guide ring group 2 also includes a third guide ring 23, which can be arranged above the second collection tank 42. The third guide ring 23 has a third guide port, and the third guide ring 23 can achieve three-level diversion of water flow to improve the efficiency of water flow entering the second collection tank 42. At the same time, the third guide ring 23 is arranged on the upper edge of the second collection tank 42, and will guide the upper opening of the first annular cavity in the inclined tube filter group 6, so that the water flow flows directly from the upper opening of the first annular cavity toward the second opening, and avoids the backflow of water flow at the second collection tank 42.

[0085] In some embodiments, a third flow guiding gap is provided between the first side wall 61 and the inner side of the cylinder shell 12, and the top of the first annular cavity is also connected to the first flow guiding gap and the third flow guiding gap.

[0086] In some embodiments, the diameter of the conical filter plate 31 gradually increases from the first opening to the second opening at a sixth preset gradient; the projection of the conical filter plate 31 in the vertical direction is placed within the projection area of ​​the second guide ring 22 in the vertical direction; the first collection groove 41 is annularly structured and is arranged circumferentially on the lower edge of the conical filter plate 31.

[0087] In this embodiment, the diameter of the conical filter plate 31 is designed to be gradually increased from the first opening to the second opening in a sixth preset gradient, which helps to form better fluid dynamic conditions when water flows through, enhances the filtering effect on sediments of different particle sizes, and thus improves the efficiency of mud-water separation. The projection of the conical filter plate 31 in the vertical direction is located within the vertical projection area of ​​the second guide ring 22, ensuring the compactness and efficiency of the filtering process, effectively utilizing the space, reducing the volume of the overall structure, and maintaining a good fluid flow path. The first collection trough 41 is annular in structure and is sleeved on the circumference of the lower edge of the conical filter plate 31, which can effectively collect the sediment settled from the conical filter plate 31, reduce the vortex and dead corners of the water flow, and make the water flow more smoothly toward the second guide ring 22, further improving the filtering efficiency of the water flow.

[0088] In some embodiments, the conical filter plate 31 is provided with a first filter hole, and the first filter hole is used to filter mud and sand; and / or, the first collecting tank 41 is provided with a plurality of second filter holes; and / or, the second collecting tank 42 is provided with a plurality of third filter holes.

[0089] In this embodiment, a first filter hole is set on the conical filter plate 31, which can effectively filter and separate the sediment entering the water flow, thereby improving the filtering efficiency of the entire separation system. By reasonably designing the size and distribution of the first filter hole, sediment of different particle sizes can be graded and filtered. A plurality of second filter holes are set on the first collection tank 41, which can further filter the sediment flowing in from the conical filter plate 31. This is not only conducive to collecting more sediment, but also can prevent fine particles from being suspended again in subsequent processes. A plurality of third filter holes are set on the second collection tank 42, which can filter the fine sediment remaining in the water flow entering from the second guide ring 22. The setting of multi-stage filter holes can grade and intercept the sediment in the water flow at different stages, which is conducive to maintaining the smooth flow of water, reducing local blockages, and optimizing the overall flow path.

[0090] In some embodiments, a first guide hole group and a second guide hole group are provided on the cover plate 11; the first guide hole group has a plurality of first guide holes 111, and the plurality of first guide holes 111 are distributed on the cover plate 11 along a first preset manner; the second guide hole group has a plurality of second guide holes, and the plurality of second guide holes are distributed on the cover plate 11 along a second preset manner; the diameters of the first guide holes 111 and the second guide holes are different.

[0091] In this embodiment, a first guide hole group and a second guide hole group are provided on the cover plate 11, which can divert and guide the water flow entering the manhole cover, optimize the water flow entry mode and flow path, and facilitate the subsequent mud and water separation process. The multiple holes of the first guide hole group and the second guide hole group are distributed on the cover plate 11 along different preset methods, which can ensure that the spatial distribution of the incoming water is more uniform, avoid excessive or too small local water flow, and improve the overall separation efficiency. The first guide hole 111 and the second guide hole have different diameters, and can divert sediment particles of different sizes, so that larger particles enter through the first guide hole 111 and smaller particles enter through the second guide hole, which is beneficial to the subsequent separation process.

[0092] In some embodiments, the first collection tank 41 is detachably connected to the cylindrical shell 12; the second collection tank 42 is detachably connected to the cylindrical shell 12. In this embodiment, the first collection tank 41 and the second collection tank 42 are detachably connected to the cylindrical shell 12, which facilitates the regular cleaning and maintenance of the collection assembly 4. When a large amount of silt accumulates in the first collection tank 41 and the second collection tank 42, the collection tanks can be quickly disassembled for cleaning to avoid affecting the normal operation of the entire system. The detachable design makes the maintenance of the first collection tank 41 and the second collection tank 42 more flexible and convenient, reduces the risk of system failure caused by blockage of the first collection tank 41 and the second collection tank 42, and improves the reliability and service life of the entire manhole cover system. The detachable collection tank design enables the manhole cover system to better adapt to the accumulation of silt under different use environments and conditions, enhancing its applicability and versatility.

[0093] In a second aspect, the present embodiment further provides an intelligent adjustment method for a mud-water separation manhole cover, which is applicable to the mud-water separation manhole cover described in the first aspect, and the method comprises:

[0094] Obtaining sediment content information from a first sensor;

[0095] Determine whether the sediment content information is within a preset threshold range, and if not, generate a first control signal and send it to the first drive unit;

[0096] The first driving unit adjusts the distance of the first support plate in the vertical direction according to the first control signal so that the second guide gap is connected with the second guide port.

[0097] The structure and equipment used in this embodiment can be understood with reference to the above text. The preset threshold refers to the upper and lower limits of the sediment content set according to actual needs. When the sediment content information exceeds this range, the corresponding control signal will be triggered. The first control signal is a signal generated by the control system when the sediment content exceeds the preset threshold range. The first control signal is used to instruct the drive unit to adjust the support plate position of the manhole cover.

[0098] Specifically, the preset threshold can be obtained by analyzing historical data: collect historical data on the sediment content in the well, including the sediment content under different weather conditions, tidal changes, and seasonal changes. Use statistical methods (such as mean, standard deviation, quantile, etc.) to analyze the historical data and identify the normal range and abnormal values ​​of the sediment content. According to the statistical characteristics of the historical data, set reasonable upper and lower limits. For example, the upper limit can be set to the 95% quantile in the historical data to ensure that the control signal will not be triggered under normal circumstances.

[0099] The first sensor monitors the sediment content in the well in real time and transmits the monitored data to the control system. After receiving the sediment content information, the control system compares it with the preset threshold. If the sediment content is not within the preset range, the control system generates a first control signal. The generated first control signal will be sent to the first drive unit to instruct it to make corresponding adjustments. The first drive unit adjusts the distance of the first support plate in the vertical direction according to the received control signal. By changing the position of the first support plate, the size of the second diversion gap is controlled so that the connecting gap between it and the second diversion port is increased or reduced to adapt to different water flow rates. By adjusting the diversion gap, the manhole cover can effectively separate sediment from water and keep the well clean and drained normally.

[0100] Through the intelligent control system, automatic monitoring and adjustment of sediment content is achieved, reducing the need for manual intervention and improving the convenience of operation. By timely adjusting the position of the first support plate, the diversion gap can be effectively maintained unobstructed, ensuring the effect of mud and water separation and improving the overall efficiency of the drainage system. By effectively separating sediment, the wear of accumulation on the manhole cover is reduced, the service life of the manhole cover and related equipment is extended, and the maintenance cost is reduced. By effectively managing and separating sediment, the pollution of the surrounding environment by sediment is prevented, the water quality is protected, and the ecological balance is promoted. The intelligent adjustment of the manhole cover can effectively avoid the safety hazards caused by sediment blockage.

[0101] In some embodiments, the first control signal includes an adjustment distance value of the first support plate in the vertical direction, and the first control signal can be obtained by the following steps:

[0102] Acquiring sediment content information of the first sensor according to a first preset frequency;

[0103] Construct a sediment increment map, generate discrete data points based on sediment content information, and plot them in the sediment increment map;

[0104] Generate sediment increment simulation curve based on discrete data points;

[0105] Obtaining an incremental slope value of a sediment incremental simulation curve, and obtaining a preset slope value corresponding to a preset threshold range;

[0106] The incremental ratio is obtained according to the incremental slope value and the preset slope value;

[0107] Obtain the average water flow velocity, multiply the increment ratio by the average water flow velocity, and obtain the predicted water flow increment;

[0108] Obtaining a cross-sectional flow velocity threshold of the second flow-guiding gap;

[0109] The adjustment distance value of the second diversion gap is obtained according to the predicted water flow increment and the cross-sectional flow velocity threshold.

[0110] In this embodiment, the first preset frequency can be a sampling frequency (such as every minute, every hour, etc.) set according to the needs of the system, and regularly obtain sediment content information from the first sensor (such as a turbidity sensor, a suspended solids sensor, etc.), and record the obtained sediment content data for subsequent analysis.

[0111] Convert the acquired sediment content information into discrete data points. For example, suppose the sediment content collected each time is C i , then at each time point t i Corresponding to a sediment content data point (C i ,). In the sediment increment graph, discrete data points are plotted with time on the X-axis and sediment content on the Y-axis.

[0112] By using interpolation or fitting (such as polynomial fitting, spline interpolation, etc.) methods, a simulation curve of sediment increment is generated based on discrete data points. This curve can smoothly represent the trend of sediment content changing over time. By taking the derivative of the sediment increment simulation curve, the incremental slope value of the curve (i.e., the rate at which sediment increment changes over time) is obtained. At a specific time t k Calculate the slope at:

[0113]

[0114] In the formula, S k is the incremental slope value, dC is the sediment increment value per unit time, and dt is the unit time.

[0115] The calculated incremental slope value is recorded for comparison with the preset slope value.

[0116] Set a preset slope value S for the change in sediment content based on actual application conditions and historical data. preset (For example, the maximum allowable change in sediment content per unit time.) The upper and lower limits of the preset slope value are determined to form a preset threshold range for subsequent judgment.

[0117] Compare the incremental slope value S calculated in real time k With the preset slope value S presetThe relationship between them is used to calculate the incremental ratio R:

[0118]

[0119] The increment ratio R reflects the proportional relationship between the real-time sediment content change and the expected change.

[0120] The average flow velocity V of the water flow in the well is obtained by the flow velocity sensor avg , can be measured based on fluid dynamics principles or the output data of a flow sensor. The calculated average water flow velocity is recorded for subsequent use.

[0121] The increment ratio is multiplied by the average water flow velocity to obtain the predicted water flow increment ΔQ:

[0122] ΔQ=R×V avg ;

[0123] The predicted water flow increment ΔQ represents the change in water flow under the current condition of changing sediment content.

[0124] According to the principles of fluid mechanics and actual operation requirements, the cross-sectional velocity threshold V of the second diversion gap is set. th , usually to ensure smooth water flow or prevent sediment accumulation. The set cross-sectional velocity threshold is recorded for subsequent calculations.

[0125] According to the comparison between the predicted water flow increment and the cross-sectional flow velocity threshold, the adjustment distance value D of the second diversion gap is calculated. The following formula can be used for calculation:

[0126] D=f(ΔQ,V th );

[0127] Wherein f is a function set according to system requirements, and may be a linear function, a nonlinear function, a step function, or a model based on a neural network, a decision tree, etc., and this embodiment is not limited to this.

[0128] This embodiment can ensure that the intelligent adjustment system of the mud-water separation manhole cover can respond in time when the mud content changes, thereby improving drainage efficiency and system reliability.

[0129] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0130] Different from the prior art, in the above technical solution, the mud-water separation manhole cover includes a body 1, a guide ring group 2, a diversion assembly 3, a collection assembly 4, a sensor assembly 5 and an inclined tube filter group 6. After the water flows into the first opening, it first passes through the first guide ring 21, and the water flows are guided by the first guide port to the conical filter plate 31 of the diversion assembly 3. The conical filter plate 31 filters large particles of sediment, which will be deposited in the first collection tank 41, while the fine sediment and the water flow pass through the conical filter plate 31 and enter the second guide port of the second guide ring 22 and enter the second collection tank 42. The water flow enters the second collection tank 42 from the bottom of the inclined tube filter group 6 and flows out from the top of the inclined tube filter group 6 under the action of gravitational potential energy, thereby flowing to the second opening. The first sensor 51 in the sensor assembly 5 detects the sediment content in the second collection tank 42 and feeds the information back to the control unit 53. The control unit 53 controls the first driving unit 52 to drive the first support plate 54 to move up and down, adjust the degree of connectivity between the second guide gap and the second guide port, thereby adjusting the flow rate of the water in the second guide gap, thereby increasing the flow rate. When the water flow is large, the first support plate 54 can be against the top of the second collecting trough 42, thereby maximizing the second guide gap, preventing the water flow from entering the second collecting trough 42 and washing away the silt, while increasing the flow rate of the water flowing out of the second opening, thereby realizing intelligent regulation of the flow rate when the water flow is large or small.

The above-mentioned integrated unit may be implemented in the form of hardware or in the form of software functional units.

Based on this understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, or all or part of the technical solution can be embodied in the form of a software product, and the computer software product is stored in a storage medium, including a number of instructions for a computer device (which can be a personal computer, server, or network device, etc.) or a processor (processor) to perform all or part of the steps of each embodiment of the present invention.
