Description

Technical Field

[0001] This invention relates to the field of drainage well cover technology, specifically to a mud-water separation well cover and an intelligent adjustment method. Background Technology

[0002] Municipal manhole covers refer to manhole covers used on municipal infrastructure such as urban roads, sidewalks, and public areas. Currently, manhole covers mainly serve the functions of anti-theft warning, ventilation, and drainage.

[0003] Chinese patent CN223163931U discloses a multifunctional manhole cover for mud-water separation. This multifunctional manhole cover includes a cover body, a cylindrical shell, a guide plate assembly, a fan blade assembly, and a collection trough. In cases of low water volume, water flows through the grid on the cover body into the guide plate assembly, enters the first guide trough, and falls. In cases of high water volume, large pieces of garbage or debris are blocked at the grid, while water and fine mud and sand flow through the grid into the guide plate assembly. A large amount of water collects at the first guide trough and falls onto the fan blades of the fan blade assembly. Driven by the water flow, the fan blades begin to rotate, using centrifugal force to carry the mud and sand to the edge of the cylindrical shell. Mixed with a small amount of residual water, the mud and sand flow from the inner wall of the cylindrical shell into the collection trough in the mud and sand guide inlet, completing the separation of mud and sand from water. This solves the problem of large amounts of mud and water clogging the manhole cover holes, promptly guiding water to the sewer and collecting excess mud and sand.

[0004] The aforementioned prior art discloses that water and fine silt flow together into the guide plate assembly through the grid. A large amount of water gathers at the first guide channel and falls onto the fan blades of the fan blade assembly. The fan blades begin to rotate under the power of the water flow. However, a lot of silt remains in the water flow, which not only easily damages the fan blades, but also reduces the rotation speed of the fan blades, affects the efficiency of silt and water separation, and reduces the effectiveness of the device.

[0005] To address the above issues, a mud-water separation manhole cover and an intelligent adjustment method are proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a mud-water separation manhole cover and an intelligent adjustment method. By using this device, the problems mentioned in the background are solved.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a mud-water separation well cover, comprising a body, with placement boxes fixedly installed on both sides near the bottom of the body, a first filter screen fixedly installed in the inner cavity of each placement box, a bent pipe inserted into the bottom of the placement box and the opposite side of the body, a grid provided near the top of the inner cavity of the body, a second filter screen fixedly installed on the rear side of the inner cavity of the body, an anti-clogging component provided at the bottom of the second filter screen, openings provided on both sides near the middle of the inner cavity of the body, a water collection trough fixedly installed near the middle of the inner cavity of the body, and a conduit inserted into the bottom of the water collection trough. The inner cavity of the placement box is equipped with a reciprocating assembly, and a cleaning assembly is provided on the opposite side of the reciprocating assembly. The anti-clogging assembly includes a turbine located in the inner cavity of the conduit. A load-bearing plate is fixedly installed near the middle of the inner cavity of the conduit. A vertical rod is installed through the top of the turbine, and the bottom end of the vertical rod is movable through the top of the load-bearing plate. A vertical rod is fixedly installed at the top of the vertical rod. Several discs are fixedly fitted on the outer periphery of the vertical rod near the top. Rectangular blocks are fixedly installed on the top of the discs near both sides. A connecting telescopic rod is fixedly installed on the opposite side of the rectangular blocks. A striking ball is fixedly installed on the opposite end of the connecting telescopic rod.

[0008] Furthermore, a connecting spring is movably sleeved on the outer periphery of the connecting telescopic rod, and the two ends of the connecting spring are fixedly connected to the striking ball and the rectangular block, respectively.

[0009] Furthermore, a support plate is rotatably connected to the outer periphery of the vertical rod near the middle position, and the support plate is fixedly connected to the inner cavity side wall of the water collection tank.

[0010] Furthermore, the reciprocating assembly includes a controller fixedly installed at the bottom of the inner cavity of the placement box near the front side, a speed sensor fixedly installed at the bottom of the load-bearing plate, a drive motor fixedly installed at the rear side of the inner cavity of the placement box, a reciprocating lead screw fixedly installed at the end of the drive motor's power output shaft, and the front end of the reciprocating lead screw being rotatably connected to the front side of the inner cavity of the placement box. A lead screw nut is movably sleeved on the outer periphery of the reciprocating lead screw near the rear end, a connecting block is fixedly installed at the bottom of the lead screw nut, a sliding seat is slidably connected to the bottom of each connecting block, and a bent rod is fixedly installed on the other side of each sliding seat.

[0011] Furthermore, a limiting block is fixedly installed on the top of the lead screw nut, and a limiting rod is movably passed through the front side of the limiting block, with both ends of the limiting rod being fixedly connected to the front and rear sides of the inner cavity of the placement box, respectively.

[0012] Furthermore, the cleaning assembly includes a movable shaft rotatably connected to the inner cavity of the placement box, a cleaning brush fixedly installed at the front end of the movable shaft, an L-shaped rod fixedly installed on one side of the sliding seat, a drive rod fixedly installed at the bottom end of the L-shaped rod, a fixing plate fixedly installed on one side of the inner cavity of the placement box, and the bottom end of the drive rod movably passes through the top of the fixing plate.

[0013] Furthermore, the top of the fixed plate is provided with a drive groove, and the bottom ends of the drive rods all movably penetrate the inner cavity of the drive groove.

[0014] Furthermore, the outer periphery of both the movable shaft and the reciprocating lead screw is fixedly fitted with synchronous pulleys, and a synchronous belt is fitted between the synchronous pulleys.

[0015] Furthermore, the bottom of each opening is arc-shaped.

[0016] A method for intelligent adjustment of mud-water separation manhole covers includes the following steps: S1: During the rainy season, rainwater falls from the grille and is separated from mud and water by the second filter screen; S2: Under the impact of the water flow, the turbine can be rotated, which in turn can rotate the upright. The vertical rod fixed on the upright can rotate several discs. During the rotation of the discs, the striking ball moves outward under the action of centrifugal force, which can then strike the second filter screen to prevent it from clogging. S3: The filtered silt is introduced into the inner cavity of the placement box through the opening; S4: When sediment accumulates on the top surface of the second filter screen, rainwater flows down through the second filter screen, causing the turbine speed to decrease. At this time, the speed sensor transmits information to the controller, which controls the drive motor power output shaft to rotate. This causes the reciprocating screw fixed to the end of the drive motor power output shaft to rotate, which in turn causes the screw nut moving around the reciprocating screw to move back and forth under the limit of the limit block and the limit rod. With the connection of the connecting block, the sliding seat can move back and forth. The bent rod fixed on the sliding seat can clean the accumulated sediment. S5: During the movement of the connecting block, with the cooperation of the drive groove, the bent rod can move backward when the L-shaped rod and the drive rod move. During the rotation of the reciprocating screw, the movable shaft can be rotated under the transmission of the synchronous pulley and the synchronous belt. When the bent rod moves to a certain position, the plastic bag on the bent rod can be cleaned by the cleaning brush.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: When cleaning the second filter, with the help of the anti-clogging component, the disc fixed on the outer circumference of the vertical rod can rotate during the rotation of the vertical rod. During the rotation of the disc, the striking ball moves outward under the action of centrifugal force, thereby striking the second filter to prevent it from clogging and improving the efficiency of mud-water separation.

[0018] When the turbine speed decreases, the screw nut that moves around the reciprocating screw can be moved with the help of the reciprocating assembly. With the connection of the connecting block, the sliding seat can move back and forth. The bent rod fixed on the sliding seat can clean the accumulated mud and sand and prevent mud and sand from accumulating.

[0019] When the connecting block moves back and forth, with the cooperation of the drive groove, the bent rod can be moved out of the inner cavity of the opening, and with the rotation of the cleaning brush, the plastic bag attached to the outer periphery of the bent rod can be cleaned, improving the subsequent cleaning effect of mud and sand.

[0024] A mud-water separation manhole cover includes a body 1. Placement boxes 2 are fixedly installed on both sides of the body 1 near the bottom. (The placement boxes 2 are used to store mud and sand. A sealing door can be installed on the placement boxes 2 during installation of the body 1 to facilitate subsequent removal of the mud and sand.) A first filter screen 5 is fixedly installed inside each of the placement boxes 2. (The mud and sand are located in the first filter screen 5, which further filters overflowing water.) A bent pipe 4 is inserted into the bottom of the placement box 2 and the opposite side of the body 1. (The bent pipe 4 can guide rainwater into the inner cavity of the body 1.) A grille 3 is provided near the top of the inner cavity of the body 1. The inner cavity of the body 1 is further... A second filter screen 6 is fixedly installed on the side. An anti-clogging component 7 is provided at the bottom of the second filter screen 6. An opening 30 is provided on both sides of the inner cavity of the main body 1 near the middle position. The bottom of the opening 30 is arc-shaped (the arc-shaped bottom of the opening 30 allows the mud and sand to be smoothly guided into the placement box 2). A water collection tank 10 is fixedly installed near the middle position of the inner cavity of the main body 1 (the water collection tank 10 collects rainwater and can provide stable power for the turbine 71). A conduit 20 is inserted into the bottom of the water collection tank 10. A reciprocating component 8 is provided in the inner cavity of the placement box 2. A cleaning component 9 is provided on the opposite side of the reciprocating component 8. The anti-clogging component 7 includes a turbine 71 located in the inner cavity of the conduit 20. A load-bearing plate 73 is fixedly installed near the middle of the inner cavity of the conduit 20. A vertical rod 72 is provided through the top of the turbine 71, and the bottom end of the vertical rod 72 is movable through the top of the load-bearing plate 73. A vertical rod 74 is fixedly installed at the top of the vertical rod 72. Several discs 75 are fixedly fitted on the outer periphery of the vertical rod 74 near the top. (The size of the discs 75 increases sequentially to improve the effect of striking the second filter screen 6.) Rectangular blocks 76 are fixedly installed near both sides of the top of the discs 75. A connecting telescopic rod 77 is fixedly installed on the opposite side of the rectangular block 76. A striking ball 78 is fixedly installed at the opposite end of the connecting telescopic rod 77.

[0025] Specifically, when cleaning the second filter screen 6, with the cooperation of the anti-clogging component 7, the disc 75 fixedly sleeved on the outer periphery of the vertical rod 74 can rotate during the rotation of the vertical rod 74. During the rotation of the disc 75, the striking ball 78 moves outward under the action of centrifugal force, thereby striking the second filter screen 6 to prevent it from clogging and improve the efficiency of mud-water separation.

[0026] A connecting spring 771 is movably sleeved on the outer periphery of the connecting telescopic rod 77, and the two ends of the connecting spring 771 are fixedly connected to the striking ball 78 and the rectangular block 76, respectively.

[0027] Specifically, when the upright 72 stops rotating, the connecting spring 771 can reset the striking ball 78, thus providing a certain degree of protection during the striking process.

[0028] A support plate 741 is rotatably connected to the outer periphery of the vertical rod 74 near the middle position, and the support plate 741 is fixedly connected to the inner cavity side wall of the water collection tank 10.

[0029] Specifically, by setting up the support plate 741, the vertical rod 74 can be supported, thereby improving the stability of the rotation of the vertical rod 74.

[0030] The reciprocating assembly 8 includes a controller 88 fixedly installed at the bottom of the inner cavity of the placement box 2 near the front side. A speed sensor 81 is fixedly installed at the bottom of the load-bearing plate 73 (the speed sensor 81 is electrically connected to the controller 88). A drive motor 82 is fixedly installed at the rear side of the inner cavity of the placement box 2. A reciprocating lead screw 83 is fixedly installed at the end of the power output shaft of the drive motor 82, and the front end of the reciprocating lead screw 83 is rotatably connected to the front side of the inner cavity of the placement box 2. A lead screw nut 84 is movably sleeved on the outer periphery of the reciprocating lead screw 83 near the rear end. A connecting block 85 is fixedly installed at the bottom of the lead screw nut 84. A sliding seat 86 is slidably connected to the bottom of each connecting block 85. A bent rod 87 is fixedly installed on the other side of each sliding seat 86.

[0031] Specifically, when the turbine 71 speed decreases, with the cooperation of the reciprocating assembly 8, the screw nut 84 that moves around the reciprocating screw 83 can move. With the connection of the connecting block 85, the sliding seat 86 can move back and forth. The bent rod 87 fixed on the sliding seat 86 can clean the accumulated mud and sand and prevent the accumulation of mud and sand.

[0032] A limiting block 841 is fixedly installed on the top of the lead screw nut 84. The front side of the limiting block 841 moves through the limiting rod 842, and the two ends of the limiting rod 842 are fixedly connected to the front and rear sides of the inner cavity of the placement box 2, respectively.

[0033] Specifically, by setting the limit block 841 and the limit rod 842, the movement of the lead screw nut 84 can be limited, thereby improving the stability of the lead screw nut 84 during movement.

[0034] The cleaning component 9 includes a movable shaft 91 rotatably connected to the inner cavity of the placement box 2. A cleaning brush 92 is fixedly installed at the front end of the movable shaft 91. An L-shaped rod 93 is fixedly installed on one side of the sliding seat 86. A drive rod 94 is fixedly installed at the bottom end of the L-shaped rod 93. A fixing plate 95 is fixedly installed on one side of the inner cavity of the placement box 2, and the bottom end of the drive rod 94 moves through the top of the fixing plate 95.

[0035] Specifically, when the connecting block 85 reciprocates, with the cooperation of the drive groove 951, the bent rod 87 can be moved out of the inner cavity of the opening 30, and with the rotation of the cleaning brush 92, the plastic bag attached to the outer periphery of the bent rod 87 can be cleaned, improving the subsequent cleaning effect of mud and sand.

[0036] The top of the fixed plate 95 is provided with a drive groove 951, and the bottom ends of the drive rods 94 all move through the inner cavity of the drive groove 951.

[0037] Both the movable shaft 91 and the reciprocating lead screw 83 are fixedly fitted with synchronous pulleys 911, and synchronous belts 912 are fitted together between the synchronous pulleys 911.

[0038] Specifically, by setting the synchronous pulley 911 and the synchronous belt 912, the movable shaft 91 and the reciprocating screw 83 can rotate synchronously.

[0039] A method for intelligent adjustment of mud-water separation manhole covers includes the following steps: S1: During the rainy season, rainwater falls from the grille 3 and separates the mud and water through the second filter screen 6; S2: Under the impact of the water flow, the turbine 71 can be rotated, which in turn can rotate the upright 72. The vertical rod 74 fixed on the upright 72 can rotate several discs 75. During the rotation of the discs 75, the striking ball 78 moves outward under the action of centrifugal force, which can then strike the second filter screen 6 to prevent it from clogging. S3: The filtered silt is introduced into the inner cavity of the placement box 2 through the opening 30; S4: When sediment accumulates on the top surface of the second filter screen 6, rainwater flows down through the second filter screen 6, causing the speed of the turbine 71 to decrease. At this time, the speed sensor 81 transmits information to the controller 88, which controls the power output shaft of the drive motor 82 to rotate, thereby enabling the reciprocating screw 83 fixed at the end of the power output shaft of the drive motor 82 to rotate. This enables the screw nut 84, which moves around the reciprocating screw 83, to reciprocate under the limit of the limit block 841 and the limit rod 842. With the connection of the connecting block 85, the sliding seat 86 can reciprocate. The bent rod 87 fixed on the sliding seat 86 can clean the accumulated sediment. S5: During the movement of the connecting block 85, with the cooperation of the drive groove 951, when the L-shaped rod 93 and the drive rod 94 move, the bent rod 87 can move to the rear. During the rotation of the reciprocating screw 83, the movable shaft 91 can be rotated under the transmission of the synchronous pulley 911 and the synchronous belt 912. When the bent rod 87 moves to a certain position, the plastic bag on the bent rod 87 can be cleaned by the cleaning brush 92.

[0040] In summary, the working principle of this invention is as follows: During the rainy season, rainwater falls from the grille 3 and separates the mud and water through the second filter screen 6. Under the impact of the water flow, the turbine 71 rotates, which in turn rotates the upright 72. The vertical rod 74 fixed on the upright 72 causes several discs 75 to rotate. During the rotation of the discs 75, the striking ball 78 moves outward under the action of centrifugal force, which in turn strikes the second filter screen 6 to prevent it from clogging and improve the efficiency of mud and water separation. The filtered mud and sand are introduced into the inner cavity of the placement box 2 through the opening 30. When the mud and sand accumulate on the top surface of the second filter screen 6, the rainwater passing through the second filter screen 6 falls, and the speed of the turbine 71 decreases. At this time, the speed sensor 81 transmits information to the controller 88, and the controller 88 controls the power output shaft of the drive motor 82 to rotate, which in turn causes the fixed The reciprocating screw 83 at the power output shaft end of the drive motor 82 rotates, thereby enabling the screw nut 84, which moves around the outer periphery of the reciprocating screw 83, to reciprocate under the limitation of the limit block 841 and the limit rod 842. With the connection of the connecting block 85, the sliding seat 86 can reciprocate. The bent rod 87 fixed on the sliding seat 86 can clean the accumulated mud and sand, preventing mud and sand accumulation. During the movement of the connecting block 85, with the cooperation of the drive groove 951, the bent rod 87 can move backward when the L-shaped rod 93 and the drive rod 94 move. During the rotation of the reciprocating screw 83, the movable shaft 91 can rotate under the transmission of the synchronous pulley 911 and the synchronous belt 912. When the bent rod 87 moves to a certain position, the plastic bag on the bent rod 87 can be cleaned by the cleaning brush 92, improving the subsequent cleaning effect of the bent rod 87.

[0041] Example 2: Operation and Maintenance of Manhole Covers for Mud and Water Separation on Municipal Roads During the Rainy Season I. This example focuses on the municipal drainage system of a main road in a city. This section of the road has a large traffic volume, concentrated rainfall during the rainy season, and rainwater mixed with mud, sand, fallen leaves, plastic bags and other debris. The mud-water separation manhole cover (including the body 1, placement box 2, grating 3 and other components) described in the document is used for drainage and mud-water separation operations. Daily operation monitoring and regular maintenance are carried out simultaneously to ensure smooth drainage and no blockage of the manhole cover during the rainy season.

[0042] II. Operational Processes Under Different Rainfall Intensities (a) Light rain (daily rainfall of 5-15 mm) After rainwater falls onto the road surface, it collects along the road slope to the manhole cover, where it is initially intercepted by the grille 3 to prevent large debris such as fallen leaves and small stones from entering the inner cavity of the main body 1. The filtered rainwater enters the inner cavity of the main body 1 and is separated into mud and water by the second filter screen 6. The rainwater falls into the water collection tank 10 through the second filter screen 6, while the mud and sand adhere to the surface of the second filter screen 6. Rainwater in the water collection tank 10 flows out slowly through the conduit 20. The water flow impacts the turbine 71, causing it to rotate at a low speed. The turbine 71 drives the upright 72 to rotate, and the vertical rod 74 at the top of the upright 72 rotates synchronously. The disc 75 on the outer periphery of the vertical rod 74 rotates slowly with the vertical rod 74. The striking balls 78 on the rectangular blocks 76 on both sides of the disc 75 are subjected to slight centrifugal force and move slightly outward through the connecting telescopic rod 77, gently tapping the surface of the second filter screen 6 to shake off a small amount of attached mud and sand. The shaken-off mud and sand slide into the inner cavity of the placement box 2 through the arc-shaped opening 30, and are filtered again by the first filter screen 5 (intercepting mud and sand, allowing rainwater to pass through). The filtered rainwater flows back to the inner cavity of the main body 1 through the bend pipe 4 and is finally discharged with the drainage system. During this process, the turbine 71 rotates at a stable speed (the speed sensor 81 detects a value of 150-200 r / min), the controller 88 does not trigger the drive motor 82, and the reciprocating assembly 8 and the cleaning assembly 9 are in standby mode.

[0043] (ii) Moderate to heavy rain (daily rainfall of 15-50 mm) With increased rainfall, a large amount of rainwater carries mud, sand and small debris from the road surface into the inner cavity of the main body 1 through the grille 3. The load on the second filter 6 increases, and the mud-water separation efficiency becomes crucial. A large amount of rainwater falls rapidly into the water collection tank 10, and forms a strong water flow through the guide pipe 20, which impacts the turbine 71 and makes it rotate at high speed (the speed sensor 81 detects a value of 300-400 r / min), and the speed of the upright pole 72 and the vertical pole 74 increases simultaneously. When the disc 75 rotates at high speed, the striking ball 78 is subjected to a large centrifugal force, the connecting telescopic rod 77 is stretched and the connecting spring 771 is deformed, and the striking ball 78 strikes the second filter screen 6 with great force, effectively preventing the rapid accumulation of mud and sand on the surface of the second filter screen 6 and ensuring the efficiency of rainwater permeation. The amount of separated mud and sand increases significantly and continues to slide into the placement box 2 along the opening 30. The first filter screen 5 efficiently intercepts the mud and sand, preventing the mud and sand from clogging the bend 4. At the same time, the support plate 741 provides stable support for the vertical rod 74, preventing the vertical rod 74 from shaking due to high-speed rotation. If a small amount of lightweight debris such as plastic bags gets tangled around the edge of the second filter screen 6, the speed of the turbine 71 will decrease slightly (down to 250-280 r / min). The speed sensor 81 will transmit the signal to the controller 88, and the controller 88 will start the drive motor 82 to run at low speed. The drive motor 82 drives the reciprocating lead screw 83 to rotate. The lead screw nut 84 moves slowly back and forth under the limit of the limit block 841 and the limit rod 842. It drives the sliding seat 86 to move through the connecting block 85. The bent rod 87 on the sliding seat 86 extends into the inner cavity of the body 1 and pushes the plastic bags and other debris on the edge of the second filter screen 6 to the opening 30, and enters the placement box 2 along with the mud and sand.

[0044] (III) Post-rainstorm maintenance work (within 12 hours after daily rainfall > 50mm) Sediment cleaning and filter inspection: After heavy rain, stubborn sediment is easily left on the surface of the second filter screen 6. Due to the reduced water flow, the speed of turbine 71 drops to below 100 r / min. The speed sensor 81 triggers the controller 88, starting the reciprocating assembly 8 to run at full load. The drive motor 82 drives the reciprocating screw 83 to rotate at high speed. The screw nut 84 drives the connecting block 85 and the sliding seat 86 to move back and forth quickly. The bent rod 87 repeatedly scrapes the surface of the second filter screen 6 to thoroughly clean the residual mud and sand to the opening 30. When the sliding seat 86 moves, it drives the L-shaped rod 93 and the drive rod 94 to move along the drive groove 951 of the fixed plate 95, so that the bent rod 87 moves to the rear side above the placement box 2. The reciprocating screw 83 drives the movable shaft 91 to rotate via the synchronous pulley 911 and the synchronous belt 912. The cleaning brush 92 on the movable shaft 91 rotates synchronously to brush and wash the plastic bags, hair and other debris attached to the bent rod 87, ensuring that there is no residual debris on the bent rod 87.

[0045] Cleaning the placement box: Open the sealed door on the side of the placement box 2 (implied design in the document for easy maintenance), and clean the mud and sand accumulated on the first filter screen 5 (about 2-3 kg / piece after heavy rain) to the dedicated cleaning vehicle to prevent mud and sand from clogging the first filter screen 5; Component inspection: Check whether the connecting telescopic rod 77 is deformed due to high-frequency impact, and whether the connecting spring 771 is corroded (it is prone to water accumulation after heavy rain and needs to be rust-proofed). If any damage is found, replace it in time; check whether there is any debris blocking the turbine 71 in the guide tube 20. If so, clean it with a special hook to ensure that the turbine 71 rotates smoothly.

[0046] III. Routine Maintenance (once a week) Performance testing: Start the controller 88 in manual mode and test the operating status of the drive motor 82, reciprocating screw 83, and movable shaft 91 to ensure that the cleaning brush 92 of the cleaning component 9 can properly contact the bent rod 87; Circuit check: Check the wiring connections between speed sensor 81 and controller 88, and between controller 88 and drive motor 82, to prevent the wiring from becoming loose due to road vibration; Filter maintenance: Use a high-pressure water gun to rinse the second filter screen 6 and the first filter screen 5 to remove fine mud and sand from the filter screen pores and restore the filter screen filtration efficiency; Lubrication and maintenance: Apply lubricating oil to the connection between the reciprocating lead screw 83, the upright 72 and the load-bearing plate 73 to reduce component wear and extend service life. Implementation effect

[0047] This example demonstrates that by combining operational adjustments with regular maintenance based on varying rainfall intensities, no water accumulation caused by manhole cover blockage occurred on the municipal road during the rainy season. The mud-water separation efficiency remained stable (mud and sand interception rate exceeded 92%). The combined use of the curved rod 87 and the cleaning brush 92 effectively solved the problem of debris entanglement. Regular sludge removal from the placement box 2 ensured long-term operational stability, meeting the actual needs of municipal road drainage operations.

10. A method for intelligent adjustment of a mud-water separation manhole cover according to any one of claims 1-9, characterized in that, Includes the following steps: S1: During the rainy season, rainwater falls from the grille (3) and is separated from the mud and water by the second filter (6); S2: Under the impact of the water flow, the turbine (71) can be rotated, which in turn can make the upright (72) rotate. The vertical rod (74) fixed on the upright (72) can make several discs (75) rotate. During the rotation of the discs (75), the striking ball (78) moves outward under the action of centrifugal force, which can then strike the second filter screen (6) to prevent it from clogging. S3: The filtered silt is introduced into the inner cavity of the placement box (2) through the opening (30); S4: When the silt accumulates on the top surface of the second filter screen (6), the rainwater passing through the second filter screen (6) falls, and the speed of the turbine (71) decreases. At this time, the speed sensor (81) transmits information to the controller (88), and the controller (88) controls the power output shaft of the drive motor (82) to rotate, which in turn enables the reciprocating screw (83) fixed at the end of the power output shaft of the drive motor (82) to rotate, which in turn enables the screw nut (84) moving around the reciprocating screw (83) to reciprocate under the limit of the limit block (841) and the limit rod (842). With the connection of the connecting block (85), the sliding seat (86) can reciprocate, and the accumulated silt can be cleaned by the bent rod (87) fixed on the sliding seat (86). S5: During the movement of the connecting block (85), with the cooperation of the drive groove (951), when the L-shaped rod (93) and the drive rod (94) move, the bent rod (87) can move to the rear. During the rotation of the reciprocating screw (83), the movable shaft (91) can be rotated under the transmission of the synchronous pulley (911) and the synchronous belt (912). When the bent rod (87) moves to a certain position, the plastic bag on the bent rod (87) can be cleaned by the cleaning brush (92).
