Description

Technical Field

[0001] The present invention relates to the technical field of urban drainage, and particularly relates to an urban drainage filtration and impurity removal structure and a using method thereof. Background Art

[0002] When rainfall occurs, the drainage outlets of cities will face the situation of mud and domestic garbage flowing in. When the rainfall is light, these impurities are relatively few and are easily carried away by the water flow. However, when the rain intensity increases, a large amount of rainwater will carry more mud and garbage, resulting in blockage at the grille of the drainage outlet, and then causing rainwater accumulation and urban waterlogging.

[0003] Currently, grilles are usually installed at the inlets of urban drainage systems to isolate large-volume garbage and impurities and prevent them from entering the interior of the drainage pipes. However, during the rainy season, rainwater will carry a large amount of garbage and impurities, causing the grilles to become blocked. The tops of the grilles will be covered with various sundries such as branches, plastic bags, and paper, seriously affecting the drainage efficiency and even possibly causing the drainage pipes to be completely blocked, triggering urban waterlogging. The traditional sewage intercepting grilles are inconvenient to clean. Since the sewage intercepting grilles are located low and fixed, workers need to bend down or use tools to reach deep into the sewage for cleaning. This not only has a high labor intensity but also poses certain safety risks. Especially when the sewage contains harmful substances, it poses a threat to the health of workers. After cleaning the impurities and garbage, vortices will be generated, and when the water flow is large, it will increase the danger to workers and is not conducive to use.

[0004] Therefore, we provide an urban drainage filtration and impurity removal structure and a using method thereof to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an urban drainage filtration and impurity removal structure and a using method thereof. Through the cooperation of a spray flushing anti-blocking component and a rapid cleaning component, it solves the problem in the prior art that the sewage intercepting grille cannot quickly complete impurity removal and requires manual dredging by workers, resulting in the inability to quickly drain the road surface water and prone to urban waterlogging.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0007] The present invention relates to a structure for filtering and removing impurities in urban drainage, which includes a well body, a spray-flushing anti-blocking component, and a rapid cleaning component. An activity shell is arranged in the inner cavity of the well body. A grille plate is arranged at the top of the activity shell. A filter plate is fixedly connected between the two sides of the inner cavity of the activity shell. The spray-flushing anti-blocking component includes an equipment shell. Both sides of the equipment shell are fixedly connected to the inner wall of the activity shell. A gas tank is fixedly connected to the bottom of the inner cavity of the equipment shell. An electromagnet is fixedly connected to the right side of the gas tank. A piston is arranged in the inner cavity of the equipment shell. A magnet block is fixedly connected to the right side of the piston. A first spring is fixedly connected to the left side of the piston. The left side of the gas tank is communicated with a three-way pipe. The top of the three-way pipe penetrates through the equipment shell and is communicated with an exhaust hood. The top of the exhaust hood is fixedly connected to the filter plate. The rapid cleaning component includes a stepped brush row. The top of the stepped brush row is fixedly connected to the grille plate. Guide rails are fixedly connected to the tops of both sides of the inner cavity of the activity shell. A second spring is fixedly connected to the front side of the inner cavity of the guide rail. A sliding plate is fixedly connected to the rear side of the second spring. The opposite sides of the two sliding plates are both fixedly connected to the grille plate.

[0008] By adopting the above technical solutions, the grille plate can filter large-volume impurities and garbage in rainwater. The filter plate can filter small-particle impurities in rainwater. The equipment shell can seal the equipment installed inside it. The electromagnet can control the movement of the magnet block and the piston. The movement of the piston can compress the air inside the gas tank. The three-way pipe can cooperate with the exhaust hood to discharge the compressed air inside the gas tank to the top of the filter plate. The stepped brush row can clean the top of the filter plate and clean the small-particle impurities filtered by it, and sweep them out of the well body. The guide rails and the sliding plates can make the grille plate move smoothly back and forth, facilitating the stepped brush row to clean the top of the filter plate. The stepped arrangement of the brushes can clean the impurities in order from large to small, preventing the brushes from deforming. The second spring can control the movement of the grille plate after the activity shell rises, facilitating the staff to control the grille plate to move back and forth, and facilitating its cleaning of the top of the filter plate.

[0009] The present invention is further arranged such that lifting mechanisms are fixedly connected to both sides of the inner cavity of the well body. The lifting mechanisms include sealing boxes. The opposite sides of the two sealing boxes are both fixedly connected to the inner wall of the well body. An electric push rod is fixedly connected to the bottom of the inner cavity of the sealing box. The top of the output end of the electric push rod penetrates through the sealing box and is fixedly connected to the activity shell through a connecting block. An intercepting frame is fixedly connected to the front side of the filter plate.

[0010] By adopting the above technical solutions, the sealing box can provide sealing protection for the electric push rod to prevent rainwater from entering the inside of the sealing box and affecting the electric push rod. The electric push rod can cooperate with the connecting block to control the lifting movement of the activity shell. The intercepting frame can filter rainwater and at the same time allow a large amount of rainwater to pour into the well body, reducing the drainage pressure.

[0011] The present invention is further configured such that a sliding rod is fixedly connected to the front side of the sealed box, and a sliding sleeve is slidably connected to the surface of the sliding rod. Both opposite sides of the two sliding sleeves are fixedly connected to the movable shell.

[0012] By adopting the above technical solution, the sliding rod and the sliding sleeve can limit the movable shell, enabling it to move up and down smoothly, improving its stability during the movement, and preventing it from tilting and shifting during the lifting process.

[0013] The present invention is further configured such that a sealing mechanism is fixedly connected to the bottom of the filter plate. The sealing mechanism includes a protective shell, the top of the protective shell is fixedly connected to the filter plate, a motor is fixedly connected to the top of the inner cavity of the protective shell, a screw rod is fixedly connected to the front side of the output end of the motor, the front side of the screw rod penetrates through the protective shell and is threadedly connected to a threaded sleeve, and a sealing frame is fixedly connected to the top of the threaded sleeve.

[0014] By adopting the above technical solution, the protective shell can protect the motor, avoiding the influence of rainwater on the motor. The screw rod can cooperate with the threaded sleeve to control the use position of the sealing frame, and the sealing frame can seal the mesh holes of the filter plate, preventing the airflow from discharging from the filter plate during jet anti-blocking.

[0015] The present invention is further configured such that sliding blocks are fixedly connected to both sides of the sealing frame, and guiding grooves are fixedly connected to both sides of the bottom of the filter plate. The top of the sliding block is slidably connected to the inner wall of the guiding groove.

[0016] By adopting the above technical solution, the sliding blocks and the guiding grooves can limit the sealing frame, enabling it to move back and forth smoothly, and preventing it from shifting during the movement.

[0017] The present invention is further configured such that installation grooves are formed on both sides of the movable shell, warning lights are fixedly connected to the inner walls of the installation grooves, and drainage notches are formed at the tops of both sides of the movable shell.

[0018] By adopting the above technical solution, the installation grooves can facilitate the installation and fixation of the warning lights. The warning lights can warn pedestrians and vehicles on the road surface after the movable shell rises, avoiding collisions, and the drainage notches can drain the accumulated water inside the well body.

[0019] The present invention is further configured such that a wireless controller is fixedly connected to the left side of the bottom inside the equipment shell, and the left side of the first spring is fixedly connected to the inner wall of the air tank.

[0020] By adopting the above technical solution, the wireless controller can facilitate the staff to control the entire equipment to operate through wireless signals, and the first spring can reset the piston when it is not being squeezed.

[0021] The present invention is further configured such that a positioning rod is fixedly connected to the right side of the inner cavity of the gas tank, and the surface of the positioning rod is slidably connected to the inner walls of the magnet block and the piston.

[0022] By adopting the above technical solution, the positioning rod can limit the magnet block and the piston, enabling them to slide stably left and right along the positioning rod.

[0023] The present invention is further configured such that a positioning groove for cooperating with the grille plate is provided at the top of the well body, and a control valve is installed on the surface of the three-way pipe.

[0024] By adopting the above technical solution, the positioning groove can facilitate the grille plate to be flush with the ground and at the same time limit the grille plate, and the control valve can control the opening and closing of the three-way pipe, enabling the compressed air inside the gas tank to be quickly discharged to the exhaust hood.

[0025] A usage method of an urban drainage filtration and impurity removal structure includes the following discharging steps: S1. In light rain weather, rainwater on the road surface is introduced into the movable shell through the grille plate, and small particle impurities in the rainwater are filtered by the filter plate, while branches or other garbage are blocked by the grille plate. When the top of the grille plate is blocked by garbage, the staff can send a control signal to the wireless controller nearby, causing the motor to start. The motor cooperates with the screw rod to control the movement of the threaded sleeve and the sealing frame. The movement of the sealing frame blocks the filter holes of the filter plate. Subsequently, the electromagnet is turned on, and the magnetic force generated by the electromagnet, which has the same magnetic pole as the magnet block, causes the magnet block to control the piston to compress the first spring, and at the same time, the air inside the gas tank is compressed. After the compression is completed, the control valve is opened. The moment the control valve is opened, the compressed air is discharged through the three-way pipe and the exhaust hood to the top of the filter plate, and the high-speed air flow is discharged through the grille plate. The discharged air flow pushes the garbage blocking the top of the grille plate away, enabling the road surface rainwater to flow into the well body normally, and at the same time facilitating the staff to clean the garbage;

[0026] S2. After the filter plate has filtered rainwater for a long time, a large amount of impurities and garbage accumulate on its top, which is likely to block the filter plate and cause it to be unable to filter normally. At this time, the staff can send a control command to the wireless controller to control the electric push rod to start. The electric push rod cooperates with the connecting block to control the upward movement of the movable shell. The movement of the movable shell lifts the filter plate and the grille plate to the outside of the well body. At this time, the grille plate is no longer limited by the well body, and the second spring returns to its original position. The second spring controls the sliding plate to slide in the guide rail, enabling the grille plate to control the stepped brush row to sweep the sludge and impurities on the top of the filter plate to the outside of the well body. The staff can push the grille plate to move back and forth continuously to improve the cleaning effect of the filter plate;

[0027] S3. In heavy rain weather, due to the increased drainage demand for road rainwater and a large amount of garbage carried in the rainwater, the grid plate alone cannot meet the drainage demand at this time. The electric push rod is used to control the movable shell to move upward. At this time, the interception frame moves to the top of the well body, and the road surface sewage directly enters the well body through the interception frame. The interception frame only filters large-volume impurities and garbage in the rainwater, and small-particle impurities directly enter the well body with the rainwater and are discharged. Due to the fast flow rate of the sewer water in heavy rain weather, small-particle impurities cannot accumulate in large quantities and will be directly discharged by the water flow. By reducing the filtration requirements in heavy rain weather, the road surface water accumulation can be quickly discharged into the well body, avoiding a large amount of water accumulation on the road surface for a long time due to the inability to quickly discharge the rainwater.

[0028] S4. While the electric push rod controls the lifting of the movable shell, the warning lights on both sides of the movable shell are turned on to remind passing people and vehicles. After the movable shell is lifted, the staff can directly clean the garbage on the surfaces of the grid plate and the filter plate, without having to bend down or use tools to reach into the sewage for cleaning. This not only facilitates the drainage work of the staff but also prevents the staff from entering the accumulated water, reducing the danger during the staff's work process.

[0029] The present invention has the following beneficial effects:

[0030] 1. Through the spray-flushing anti-blocking component of the present invention, the piston is driven to compress the air in the air tank by the magnetic pole repulsion force between the electromagnet and the magnet block, and the high-pressure air flow is instantaneously released through the exhaust hood to directly impact the blockage on the surface of the grid plate. This effectively solves the problem that traditional grid manual cleaning requires bending down to contact the sewage. This component can be remotely controlled by the staff using a wireless signal, and the blocked garbage layer can be quickly dredged without manual intervention, avoiding waterlogging on the road surface caused by stagnant water accumulation. By replacing manual tool digging with air flow impact, it not only eliminates the danger of vortex suction to personnel during the cleaning process but also avoids the risk of contact with harmful substances, significantly improving the emergency response speed and operation safety of the drainage system.

[0031] 2. Through the quick cleaning component of the present invention, with the linkage design of the stepped brush row and the spring reset guide rail, when the movable shell is lifted by the lifting mechanism, the second spring drives the sliding plate to drive the grid plate to move reciprocally, so that the stepped brush row sequentially scrapes the sludge and small-particle impurities deposited on the surface of the filter plate. By the lifting operation, the filter plate is exposed to the ground surface, and combined with the stepped brush bristles that are gradually thinned from thick to thin for sweeping, it not only avoids the deformation of the brush bristles but also realizes efficient silt cleaning, greatly reducing the labor intensity. At the same time, the warning lights synchronously warn pedestrians and vehicles to ensure the safety of open-air operations, solving the problems of low efficiency and high danger in manual cleaning of existing drainage filtration mechanisms.

The control valve can control the opening and closing of the three-way pipe 270, enabling the compressed air inside the air tank 220 to be quickly discharged to the exhaust hood 280.

[0055] A usage method of an urban drainage filtration and impurity removal structure includes the following discharging steps: S1. In light rain weather, the rainwater on the road surface is introduced into the interior of the movable housing 110 through the grille plate 120. The small particle impurities in the rainwater are filtered by the filter plate 130, and branches or other garbage are blocked by the grille plate 120. When the top of the grille plate 120 is blocked by garbage, the staff near it can send a control signal to the wireless controller, causing the motor 520 to start. The motor 520 cooperates with the screw rod 530 to control the movement of the threaded sleeve 540 and the sealing frame 550. The movement of the sealing frame 550 blocks the filter holes of the filter plate 130. Subsequently, the electromagnet 230 is turned on. Through the magnetic force generated by the electromagnet 230 with the same magnetic pole as the magnet block 250, the magnet block 250 controls the piston 240 to compress the first spring 260. At the same time, the air inside the air tank 220 is compressed. After the compression is completed, the control valve is opened. The moment the control valve is opened, the compressed air is discharged to the top of the filter plate 130 through the three-way pipe 270 and the exhaust hood 280. The high-speed airflow is discharged through the grille plate 120, and the discharged airflow pushes away the garbage blocking the top of the grille plate 120, enabling the rainwater on the road surface to flow into the well body 100 normally, and at the same time facilitating the staff to clean the garbage;

[0056] S2. After the filter plate 130 has filtered rainwater for a long time, a large amount of impurities and garbage accumulate on its top, which is likely to clog the filter plate 130 and cause it to be unable to filter normally. At this time, the staff can send a control command to the wireless controller to control the electric push rod 420 to start. The electric push rod 420 cooperates with the connecting block 430 to control the movable shell 110 to move upward. The movement of the movable shell 110 lifts the filter plate 130 and the grille plate 120 to the outside of the well body 100. At this time, the grille plate 120 is no longer limited by the well body 100, and the second spring 330 resets. The second spring 330 controls the sliding plate 340 to slide in the guide rail 320, so that the grille plate 120 controls the stepped brush row 310 to sweep the sludge and impurities on the top of the filter plate 130 to the outside of the well body 100. The staff can push the grille plate 120 to move back and forth continuously to improve the cleaning effect of the filter plate 130;

[0057] S3. In heavy rain, due to the increased drainage demand of road rainwater and a large amount of garbage carried in the rainwater, at this time, only relying on the grille plate 120 cannot meet the drainage demand. The electric push rod 420 is used to control the movable shell 110 to move upward. At this time, the interception frame 440 moves to the top of the well body 100, and the road surface sewage directly enters the well body 100 through the interception frame 440. The interception frame 440 only filters large-volume impurities and garbage in the rainwater, and small-particle impurities directly enter the well body 100 with the rainwater and are discharged. Due to the fast flow rate of the sewer water in heavy rain, small-particle impurities cannot accumulate in large quantities and will be directly discharged by the water flow. By reducing the filtration requirements in heavy rain, the road surface water can be quickly drained into the well body 100, avoiding a large amount of water accumulation on the road surface for a long time due to the inability to quickly drain rainwater;

[0058] S4. When the electric push rod 420 controls the movable shell 110 to rise, the warning lights 140 on both sides of the movable shell 110 are turned on. The warning lights 140 are used to remind passing people and vehicles. After the movable shell 110 is lifted, the staff can directly clean the garbage on the surfaces of the grille plate 120 and the filter plate 130 without bending down or using tools to reach into the sewage for cleaning. This not only facilitates the drainage work of the staff but also prevents the staff from entering the accumulated water, reducing the danger during the staff's work process.

[0059] The above publicly disclosed preferred embodiments of the present invention are only used to help explain the present invention. The preferred embodiments do not describe all details in detail, nor do they limit the invention to the specific embodiments described. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, so that those skilled in the relevant technical fields can understand and utilize the present invention well.

10. A method for using a city drainage filtering and impurity removal structure according to any one of claims 1 to 9, characterized in that: The method comprises the following discharging steps: S1. In light rain weather, rainwater from the road surface is introduced into the interior of the movable shell (110) through the grille plate (120), and small particles of impurities in the rainwater are filtered through the filter plate (130), and branches or other garbage are blocked by the grille plate (120). When the top of the grille plate (120) is blocked by garbage, a worker nearby can send a control signal to the wireless controller to start the motor (520), and the motor (520) cooperates with the screw rod (530) to control the movement of the threaded sleeve (540) and the sealing frame (550), and the sealing frame (550) moves to block the filter mesh of the filter plate (130), and then the electromagnet (130) is turned on. 230), the magnet (230) generates a magnetic force with the same magnetic pole as that of the magnet block (250), so that the magnet block (250) controls the piston (240) to compress the first spring (260), and at the same time, the air inside the gas tank (220) is compressed. After the compression is completed, the control valve is opened. At the moment when the control valve is opened, the compressed air is discharged to the top of the filter plate (130) through the three-way pipe (270) and the exhaust cover (280), and the high-speed airflow is discharged through the grille plate (120). The discharged airflow pushes away the garbage blocked on the top of the grille plate (120), so that rainwater on the road surface can flow normally into the well body (100), and it is also convenient for the staff to clean up the garbage; S2. After filtering rainwater for a long time, a large amount of impurities and garbage accumulate on the top of the filter plate (130), which may easily cause clogging of the filter plate (130), causing it to be unable to filter normally. At this time, the staff can send a control command to the wireless controller to control the electric push rod (420) to start, and the electric push rod (420) and the connecting block (430) cooperate to control the movable shell (110) to move upward, and the movable shell (110) moves to lift the filter plate (130) and the grid plate (120) to the well body. (100), at which time the grid plate (120) is no longer limited by the well body (100), the second spring (330) is reset, and the second spring (330) controls the slide plate (340) to slide in the guide rail (320), so that the grid plate (120) controls the stepped brush row (310) to clean the sludge and impurities on the top of the filter plate (130) to the outside of the well body (100), and the staff can push the grid plate (120) to move back and forth continuously, thereby improving the cleaning effect of the filter plate (130); S3. In heavy rain weather, due to the increased demand for drainage of road rainwater and the large amount of garbage carried in the rainwater, the grating plate (120) alone cannot meet the drainage demand. The movable shell (110) is controlled to move upward by the electric push rod (420). At this time, the interception frame (440) moves to the top of the well body (100), and the road sewage directly enters the well body (100) through the interception frame (440). Only large-volume impurities and garbage in the rainwater are filtered by the interception frame (440), and small particles of impurities directly enter the well body (100) with the rainwater and are discharged. Due to the fast flow speed of the sewer in heavy rain weather, small particles of impurities cannot be deposited in large quantities and will be directly discharged by the water flow. By reducing the filtering requirements in heavy rain weather, the road surface water can be quickly discharged into the well body (100), avoiding the long-term accumulation of large amounts of water on the road surface caused by the inability to quickly discharge rainwater; S4. While the electric push rod (420) controls the movable shell (110) to rise, the warning lights (140) on both sides of the movable shell (110) are turned on, and the warning lights (140) are used to remind people and vehicles passing by. After the movable shell (110) is lifted, the staff can directly clean the garbage on the surface of the grid plate (120) and the filter plate (130) without bending over or using tools to go deep into the sewage for cleaning. This not only facilitates the drainage work of the staff, but also prevents the staff from entering the accumulated water, thereby reducing the danger of the staff during the work process.
