A drainage structure

Abstract

This invention relates to the field of drainage engineering technology and provides a drainage structure. During installation, the entire pipe is embedded in the inlet of a drainage ditch, and the mounting plate is embedded in the ground. Before rainwater enters the pipe through the through-holes in the cover plate, the cover plate can screen larger debris, while the filter plate can filter smaller debris such as leaves. While ensuring the water inlet speed of the cover plate, multiple filtrations of debris in the rainwater can be achieved, effectively preventing debris from clogging the drainage pipe. Furthermore, the cleaning mechanism, sealing door, and collection troughs allow for easy removal of debris from the filter plate when a large amount of debris accumulates. Two shovels in the cleaning mechanism can shovel the debris to the sides and into the two collection troughs through the discharge port, effectively preventing the filter plate from becoming clogged. Later, simply pulling up the top plate pulls out the collection trough, facilitating the cleaning of debris within.

Description

Technical Field

[0001] This invention relates to the field of drainage engineering technology, specifically a drainage structure. Background Technology

[0002] In urban drainage systems, rainwater mainly enters drainage pipes through drainage ditches. For safety reasons and to prevent garbage, fallen leaves and other debris from falling into the ditches and causing blockages, drainage ditches are generally covered with drainage ditch covers.

[0003] Existing drainage ditch covers typically have large channels to ensure sufficient water inflow. During rainfall, rainwater mixed with small debris such as garbage and fallen leaves can still fall into the ditch and cause blockages. To prevent these debris from entering the ditch and causing blockages while ensuring sufficient water inflow through the cover, appropriate technical solutions need to be designed to address these technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a drainage structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A drainage structure includes a cover plate, a mounting plate, a pipe, a filter plate, and a collection trough. The mounting plate is fixedly installed outside the pipe, while the cover plate and the filter plate are both installed inside the pipe. A cleaning mechanism for cleaning debris from the filter plate is also provided inside the pipe. The cleaning mechanism includes a pair of shovels movably mounted on the filter plate and a drive assembly for driving the two shovels to move relative to each other. A slag discharge port is symmetrically provided on the side wall of the pipe above the filter plate. A sealing door is movably installed inside the slag discharge port via a rotating shaft and is driven by a control assembly provided inside the pipe. First slide rails are symmetrically provided on both sides of the outer side wall of the pipe corresponding to the sealing door. The collection trough is installed on the outer side wall of the pipe via the first slide rails and is connected to a top plate embedded in the mounting plate via multiple connecting plates.

[0007] As a further aspect of the present invention: the driving assembly includes guide rods, a first float plate, a second float plate, and push-pull rods. Multiple guide rods are provided, all fixedly disposed between the filter plate and the cover plate, and are divided into three groups. The first float plate is movably mounted on the middle group of guide rods, and a telescopic spring is sleeved on the rod body located between the first float plate and the cover plate. The second float plate is mounted on the guide rods on both sides of the first float plate, and is connected to the first float plate via multiple fixing rods. Both sides of the first float plate are connected to the side shovels via multiple push-pull rods, wherein the two ends of the push-pull rods are hinged to the sides of the first float plate and the shovels, respectively.

[0008] As a further embodiment of the present invention: the control component includes a drive gear, a rack, a movable rod, and a second slide rail. The drive gear is installed at both ends of the rotating shaft that passes through the side wall of the pipe. The rack is slidably mounted on the outer side wall of the pipe via the second slide rail. Two levers are fixedly installed on the side of the rack away from the drive gear. The movable rod is fixedly installed at both ends of the second float plate. The movement trajectory of the movable plate interferes with the movement trajectory of the two levers. The side wall of the pipe has a side hole for the movable rod to slide.

[0009] As a further aspect of the present invention, multiple limiting plates are also fixedly installed on the outer wall of the pipe corresponding to the slag discharge port position.

[0010] As a further embodiment of the present invention: the driving assembly further includes a guide unit, the guide unit including a third slide rail symmetrically installed on the inner wall of the pipe, and guide columns that slide in cooperation with the third slide rail are fixedly installed at both ends of the shovel plate.

[0011] As a further aspect of the present invention: the third slide rail is a rectangular ring structure.

[0012] As a further aspect of the present invention: the guiding unit further includes an attraction and repulsion module, the attraction and repulsion module including a first magnet fixedly embedded on the bottom surface of the shovel plate, a second magnet with the opposite magnetic pole to the first magnet, and a second magnet with the same magnetic pole as the first magnet. The second magnet and the third magnet are both fixedly embedded on the filter plate and are respectively located at both ends of the third slide rail.

[0013] As a further aspect of the present invention: a fixing plate is also fixedly installed on a set of guide rods in the middle, and multiple fourth magnets are symmetrically embedded on both sides of the fixing plate, and a fifth magnet with the opposite magnetic pole to the fourth magnet is embedded on the side of the shovel plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention, through the installation of an mounting plate, pipes, and filter plates, allows the drainage structure to be installed with the entire pipe embedded in the inlet of the drainage ditch and the mounting plate embedded in the ground. Before rainwater enters the pipe through the through-holes in the cover plate, the cover plate can filter larger debris, while the filter plate can filter smaller debris such as leaves. While ensuring the water inflow rate through the cover plate, multiple filtrations of rainwater debris can be achieved, effectively preventing debris from clogging the drainage pipes. Furthermore, the cleaning mechanism, sealing door, control components, and collection troughs allow for easy removal of debris from the filter plate when a large amount of debris accumulates. Two shovels in the cleaning mechanism can shovel the debris to the sides and into the two collection troughs through the discharge port, effectively preventing the filter plate from becoming clogged. Later, simply pulling up the top plate pulls out the collection troughs, facilitating the removal of debris. Attached Figure Description

Implementation

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Please see Figure 1-5A drainage structure includes a cover plate 1, a mounting plate 2, a pipe 3, a filter plate 4, and a collection trough 5. The mounting plate 2 is fixedly installed outside the pipe 3, while the cover plate 1 and the filter plate 4 are both installed inside the pipe 3. A cleaning mechanism for cleaning debris from the filter plate 4 is also provided inside the pipe 3. The cleaning mechanism includes a pair of shovels 6 movably mounted on the filter plate 4 and a driving assembly for driving the two shovels 6 to move relative to each other. A slag discharge port 7 is symmetrically provided on the side wall of the pipe 3 above the filter plate 4. A sealing door 8 is movably installed in the slag discharge port 7 via a rotating shaft 9 and is driven by a control assembly provided inside the pipe 3. First slide rails 10 are symmetrically provided on both sides of the outer side wall of the pipe 3 corresponding to the sealing door 8. The bottom of the collection trough 5 has a mesh structure. The collection trough 5 is installed on the outer side wall of the pipe 3 via the first slide rails 10, and the collection trough 5 is connected to the top of the pipe 3 embedded in the mounting plate 2 via multiple connecting plates 11. The plates 12 are connected. When installing this drainage structure, the entire pipe 3 is embedded in the inlet of the drainage ditch, and the mounting plate 2 is embedded in the ground. Before rainwater enters the pipe 3 through the through hole on the cover plate 1, the cover plate 1 can screen larger debris, while the filter plate 4 can filter some small debris such as leaves. Under the premise of ensuring the water inlet speed of the cover plate 1, multiple filtrations of debris in the rainwater can be achieved, effectively avoiding the phenomenon of debris clogging the drainage pipe. In addition, the setting of the cleaning mechanism, sealing door 8, control components and collection tank 5, when there is a lot of debris accumulated on the filter plate 4, the two shovels 6 in the cleaning mechanism can shovel the debris on the filter plate 4 to both sides and enter the two collection tanks 5 through the slag discharge port 7, effectively avoiding the phenomenon of the filter plate 4 being blocked. Later, simply pull the top plate 12 upward to pull out the collection tank 5, which can be easily cleaned of the debris in the collection tank 5.

[0024] Preferably, the drive assembly includes guide rods 13, a first float plate 14, a second float plate 15, and push-pull rods 18. Multiple guide rods 13 are provided, each fixedly positioned between the filter plate 4 and the cover plate 1. The guide rods 13 are divided into three groups. The first float plate 14 is movably mounted on the middle group of guide rods 13, and a telescopic spring 17 is sleeved on the rod body of the guide rod 13 located between the first float plate 14 and the cover plate 1. The second float plate 15 is mounted on the guide rods 13 on both sides of the first float plate 14, and is connected to the first float plate 14 via multiple fixing rods 16. Both sides of the first float plate 14 are connected to the side shovel plates 6 via multiple push-pull rods 18, wherein the two ends of the push-pull rods 18 are hinged to the sides of the first float plate 14 and the shovel plates 6, respectively. When a large amount of debris accumulates on the filter plate 4, the drainage efficiency of the filter plate 4 decreases, and the amount of rainwater between the filter plate 4 and the cover plate 1 gradually increases. The first float 14 and the second float 15 move upward under the action of buoyancy. Through the transmission of the push-pull rod 18, the two shovels 6 can be driven to move closer to each other. After the first float 14 rises to a certain position, the control component controls the sealing door 8 to rotate. At this time, the slag discharge port 7 is opened. After the rainwater mixed with some debris enters the collection tank 5 through the slag discharge port 7, the first float 14 moves downward under the action of multiple telescopic springs 17 and pushes the shovels 6 to shovel the debris attached to the filter plate 4 to the position of the slag discharge port 7 and fall into the collection tank 5. The entire drive component does not require electronic components for control, which reduces production costs and subsequent maintenance costs.

[0025] Preferably, the control assembly includes a drive gear 19, a rack 20, a movable rod 21, and a second slide rail 22. Drive gears 19 are installed at both ends of the rotating shaft 9 extending through the side wall of the pipe 3. The rack 20 is slidably mounted on the outer side wall of the pipe 3 via the second slide rail 22, and two levers 23 are fixedly installed on the side of the rack 20 away from the drive gear 19. The movable rod 21 is fixedly installed at both ends of the second float plate 15, and the movement trajectory of the movable rod interferes with the movement trajectory of the two levers 23. A side hole 24 is provided on the side wall of the pipe 3 for the movable rod 21 to slide. The second float plate 15 moves with the first float... As the second float 14 moves upward, the movable rods 21 at both ends of the second float 15 move upward accordingly. After the movable rods 21 push the rack 20 connected to the deflector plate 23 upward, they can drive the rotating shaft 9 to rotate and cause the sealing door 8 to flip into the pipe 3, thereby opening the slag discharge port 7. Conversely, when the second float 15 moves downward, after the debris enters the collection tank 5 through the slag discharge port 7, the movable rods 21 on the second float 15 drive the rack 20 to reset, and cause the sealing door 8 to close the slag discharge port 7 again. The entire control assembly does not require the control of electronic components, reducing production costs and subsequent maintenance costs.

[0026] In order to prevent the sealing door 8 from flipping outwards from the pipe 3 under the action of water pressure after the sealing door 8 is closed, multiple limiting plates 25 are fixedly installed on the outer wall of the pipe 3 corresponding to the slag discharge port 7. The setting of the limiting plates 25 can effectively prevent the sealing door 8 from continuing to flip outwards from the pipe 3 after it is closed.

[0027] In addition, in order to ensure that the scraper plate 6 can stably remove debris from the filter plate 4, the drive assembly in this application also includes a guide unit. The guide unit includes a third slide rail 26 symmetrically installed on the inner wall of the pipe 3, and guide columns that slide in cooperation with the third slide rail 26 are fixedly installed at both ends of the scraper plate 6.

[0028] Preferably, the third slide rail 26 is a rectangular ring structure. With this arrangement, when the shovel plate 6 moves towards the sealing door 8, the guide column is located in the track below the third slide rail 26. At this time, the bottom surface of the shovel plate 6 is in close contact with the surface of the filter plate 4, which can remove debris from the filter plate 4. When the shovel plate 6 moves closer to the first floating plate 14, the guide column slides into the track above the third slide rail 26, which can avoid pushing subsequent debris to the middle position of the filter plate 4, ensuring that the shovel plate 6 can push debris to the slag discharge port 7 in one direction, thus improving the cleaning effect of debris on the filter plate 4.

[0029] Furthermore, to ensure that the guide posts at both ends of the shovel plate 6 can slide alternately within the upper and lower tracks of the third slide rail 26, the guide unit in this application also includes an attraction and repulsion module. The attraction and repulsion module includes a first magnet 27 fixedly embedded on the bottom surface of the shovel plate 6, a second magnet 28 with the opposite magnetic pole to the first magnet 27, and a second magnet 28 with the same magnetic pole as the first magnet 27. Both the second magnet 28 and the third magnet 29 are fixedly embedded on the filter plate 4 and are located at both ends of the third slide rail 26, respectively. Specifically, the second magnet 28 is fixedly embedded... On the filter plate 4 near the middle guide rod 13, the third magnet 29 is embedded on the filter plate 4 near the sealing door 8. When the shovel plate 6 moves to the slag discharge port 7, the first magnet 27 and the third magnet 29 move upward under the action of like poles repulsion, and cause the guide column to slide into the upper track of the third slide rail 26. When the shovel plate 6 moves to the position near the second float plate 15, the first magnet 27 and the second magnet 28 move downward under the action of opposite poles attraction, and cause the guide column to slide into the lower track of the third slide rail 26.

[0030] Furthermore, during the process of the push-pull rod 18 driving the two shovel plates 6 to move closer to each other, in order to ensure that the guide post on the shovel plate 6 can move stably to the corner of the third slide rail 26, a fixing plate 30 is also fixedly installed on the middle set of guide rods 13 in this application. Multiple fourth magnets 31 are symmetrically embedded on both sides of the fixing plate 30, and a fifth magnet 32 ​​with the opposite magnetic pole to the fourth magnet 31 is embedded on the side of the shovel plate 6.
