Abstract
Description
Technical Field
[0001] This application belongs to the field of drainage pipe technology, specifically an anti-clogging drainage pipe. Background Technology
[0002] Drainage pipes refer to the pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater. They are generally divided into three categories: rainwater pipes, sewage pipes, and combined sewer pipes. They are mainly used in urban areas, industrial areas, and residential areas to ensure smooth drainage and prevent water accumulation from adversely affecting the environment and people's lives.
[0003] As disclosed in announcement number CN221589819U, an anti-clogging drainage pipe relates to the field of drainage pipe technology. This anti-clogging drainage pipe includes a pipe body and a cover plate. It also features a cleaning structure, including a motor, a moving block, a collection trough, and two threaded rods. The right surface of the moving block is fixedly connected to the left surface of the collection trough. Both threaded rods are located inside a fixed frame and are threadedly connected to the moving block through two threaded holes. When excessive impurities accumulate on the filter screen, the motor is activated. The motor's output port drives a short rod and a drive gear to rotate. At this time, the moving block, threadedly connected to the two threaded rods, moves the collection trough to the right. The collection trough scrapes against the filter screen at the right end, ultimately collecting the impurities on the filter screen. This prevents impurities from continuously accumulating on the filter screen and restricting drainage, thus preventing the drainage pipe from becoming clogged.
[0004] However, in actual use, it was found that rainwater usually carries debris such as branches and leaves to the pipe opening, easily causing blockages. The traditional method to prevent blockages is to use a filter screen. However, during use, a large amount of debris accumulates on the surface of the pipe opening, which makes the anti-blocking process ineffective. Therefore, it is necessary to design a component that can block debris from the outside while preventing it from remaining on the filter layer surface. Utility Model Content
[0005] The purpose of this application is to provide an anti-clogging drainage pipe to solve the problem mentioned above of preventing debris from remaining on the surface of the filter layer while blocking it from the outside.
[0006] The technical solution adopted in this application is as follows: a clog-proof drainage pipe, wherein multiple sliding slots are fixedly connected to the inner side surface of the drainage tube cavity, multiple clamps are fixedly connected to one end side surface of the sliding slots relative to the drainage tube cavity, multiple positioning holes are opened on the side surface of the clamps, positioning bolts are slidably inserted into the positioning holes through the holes, a connecting rod is inserted into one end side surface of the positioning bolt relative to the positioning hole, a filter slope is fixedly connected to the side surface of the connecting rod, and multiple filter holes are opened on the side surface of the filter slope.
[0007] By adopting the above technical solution, operators use the drainage tube cavity as the initial drainage component. Water enters the drainage tube cavity, and an installation assembly consisting of a sliding slot, clamp, positioning hole, and positioning bolt is used to install the anti-clogging filter assembly, which includes the connecting rod, filter slope, and filter holes, into a suitable position. When the water carrying debris first comes into contact with the filter slope, the water seeps downward through the filter holes, while the debris remaining on the surface rolls off the filter slope to the adjacent area, avoiding secondary clogging problems caused by its accumulation. Furthermore, the entire structure is easy to disassemble and assemble, facilitating regular cleaning.
[0008] The drainage pipe cavity, serving as the wastewater inlet, is a large-volume box-shaped structure. This facilitates the installation of the filter components and slows the water flow, making it easier to process. A sliding slot, shaped like a T-slot with a bottom baffle, serves as the connecting component. Side clamps secure the external components, and positioning holes provide positioning. This combination creates a component for precise installation, offering the anti-clogging filter components a degree of flexibility in installation.
[0009] The connecting rod and clamp are connected together using positioning bolts. These bolts are easy to install and remove, significantly reducing labor during regular cleaning. The connecting rod, as a connecting rod-like component, has a filter slope fixedly connected to its side surface, which plays a crucial role in preventing clogging. The filter slope itself is an inclined surface with multiple filter holes. As water flows down through these holes, a large amount of debris cannot remain on the surface of the filter slope and instead rolls off to other areas, thus preventing secondary clogging.
[0010] In a preferred embodiment, a plurality of connecting plates are connected to the side surface of the filter slope, and a collection trough is fixedly connected to the side surface of the connecting plates.
[0011] By adopting the above technical solution, a connecting plate is used as a connecting component to connect with the edge surface of the filter slope, so that the collection tanks are distributed on both sides of the filter slope to collect the debris rolling down from the filter slope, thus avoiding the risk of structural jamming caused by the random placement of debris.
[0012] In a preferred embodiment, the side surface of the connecting plate is provided with a plurality of connecting bolts.
[0013] By adopting the above technical solution, connecting bolts are used as connecting components to connect the connecting plate and the filter slope together, and to facilitate disassembly and subsequent cleaning.
[0014] In a preferred embodiment, a secondary filter screen is provided on the inner side surface of the oral cavity of the drainage tube.
[0015] By adopting the above technical solution, a two-stage filter screen is used as a preliminary filter before sewage enters the pipeline, which filters out the finer parts.
[0016] In a preferred embodiment, a primary filter screen is provided on the bottom surface of the oral cavity of the drainage tube.
[0017] By adopting the above technical solution, a primary filter screen is used as a direct filter screen at the pipe inlet, which plays a protective role and prevents some debris from accidentally falling into the pipe.
[0018] In a preferred embodiment, a drain pipe is fixedly inserted into the bottom surface of the oral cavity of the drainage tube.
[0019] By adopting the above technical solution, a sewage pipe is used as a sewage discharge pipeline component to discharge sewage.
[0020] In a preferred embodiment, a plurality of mounting pads are fixedly connected to the side surface of the oral cavity of the drainage tube.
[0021] By adopting the above technical solution, the mounting pad is used as the connecting component for installation.
[0022] In a preferred embodiment, the side surface of the mounting pad is provided with a plurality of mounting holes.
[0023] By adopting the above technical solution, the entire device can be installed in a suitable position using mounting holes.
[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:
[0025] In this application, the drainage tube cavity serves as the inlet component for wastewater discharge. It is a large-volume box-shaped structure, facilitating the installation of the filter component while also slowing the water flow rate for easier treatment. A sliding slot, shaped with a T-shaped opening and a bottom baffle, is used as the connecting component. A side clamp secures the external component, and positioning holes provide positioning. This configuration creates a component for precise installation, granting the anti-clogging filter component a degree of installation freedom.
[0026] The connecting rod and clamp are connected together using positioning bolts. These bolts are easy to install and remove, significantly reducing labor during regular cleaning. The connecting rod, as a connecting rod-like component, has a filter slope fixedly connected to its side surface, which plays a crucial role in preventing clogging. The filter slope itself is an inclined surface with multiple filter holes. As water flows down through these holes, a large amount of debris cannot remain on the surface of the filter slope and rolls off to other areas, thus preventing secondary clogging. The entire structure is easy to disassemble and install, facilitating regular cleaning. Attached Figure Description

[0034] Example: A clog-proof drainage pipe, wherein multiple sliding slots 2 are fixedly connected to the inner side surface of the drainage tube oral chamber 1, and multiple clamping plates 3 are fixedly connected to one end side surface of the sliding slots 2 relative to the drainage tube oral chamber 1. Multiple positioning holes 4 are opened on the side surface of the clamping plates 3, and positioning bolts 5 are slidably inserted into the positioning holes 4 through the holes. A connecting rod 6 is inserted into one end side surface of the positioning bolt 5 relative to the positioning hole 4. A filter slope 7 is fixedly connected to the side surface of the connecting rod 6, and multiple filter holes 8 are opened on the side surface of the filter slope 7.
[0035] The operator uses the drainage tube cavity 1 as the initial drainage component. Water enters the drainage tube cavity 1, and the installation assembly consisting of the sliding slot 2, clamp 3, positioning hole 4, and positioning bolt 5 is used to install the anti-clogging filter assembly formed by the connecting rod 6, filter slope 7, and filter hole 8 into a suitable position. When the water carrying debris first comes into contact with the filter slope 7, the water seeps downward through the filter hole 8, while the debris remaining on the surface rolls off the filter slope to the adjacent area, avoiding secondary clogging problems caused by its accumulation. Furthermore, the entire structure can be easily disassembled and cleaned regularly.
[0036] The drainage pipe cavity 1 serves as the inlet component for wastewater discharge. It is a large-volume box-shaped structure, facilitating the installation of the filter components while also slowing the water flow for easier treatment. The sliding slot 2, a T-shaped slot with a baffle at the bottom, acts as the connecting component. The side-connected clamping plate 3 secures the external components, and the positioning hole 4 on it provides positioning. This configuration creates a component for precise positioning and installation, giving the anti-clogging filter components a degree of installation freedom.
[0037] The connecting rod 6 and the clamping plate 3 are connected together using positioning bolts 5. The positioning bolts 5 are easy to install and remove, which reduces a lot of labor during subsequent periodic cleaning. The connecting rod 6, as a connecting rod-shaped component, has a filter slope 7 fixedly connected to its side surface, which plays the main role of preventing clogging. The filter slope 7 itself is a sloped object with multiple filter holes 8. After water flows down through the filter holes 8, a large amount of debris cannot be retained on the surface of the filter slope 7 and can only roll off to other places, thus avoiding secondary clogging.
[0038] Multiple connecting plates 9 are connected to the side surface of the filter slope 7, and collection grooves 10 are fixedly connected to the side surface of the connecting plates 9. The connecting plates 9 are used as connecting components to connect with the edge surface of the filter slope 7, so that the collection grooves 10 are distributed on both sides of the filter slope 7 to collect the debris that rolls down from the filter slope 7, avoiding the risk of structural jamming caused by the random placement of debris.
[0039] Multiple connecting bolts 11 are provided on the side surface of the connecting plate 9. The connecting bolts 11 are used as connecting components to connect the connecting plate 9 and the filter slope 7 together, and to facilitate disassembly and subsequent cleaning.
[0040] A secondary filter screen 12 is installed on the inner side surface of the drainage tube oral chamber 1. The secondary filter screen 12 is used as a preliminary filter for sewage before it enters the pipe, to filter out the finer particles.
[0041] A primary filter 13 is installed on the bottom surface of the oral cavity 1 of the drainage tube. The primary filter 13 serves as a direct filter at the tube opening, providing protection and preventing some debris from accidentally falling into the tube.
[0042] A drain pipe 14 is fixedly inserted into the bottom surface of the oral cavity 1 of the drainage tube. The drain pipe 14 is used as a sewage discharge pipe component to discharge sewage.
[0043] Multiple mounting plates 15 are fixedly connected to the side surface of the oral cavity 1 of the drainage tube. The mounting plates 15 are used as connecting components for installation.
[0044] The mounting plate 15 has multiple mounting holes 16 on its side surface. The entire device is installed in a suitable position using the mounting holes 16.
[0045] The implementation principle of this anti-clogging drainage pipe embodiment is as follows: The operator uses the drainage pipe cavity 1 as the initial drainage component. Water enters the drainage pipe cavity 1. An installation assembly consisting of a sliding slot 2, clamping plate 3, positioning hole 4, and positioning bolt 5 is used to install the anti-clogging filter assembly formed by the connecting rod 6, filter slope 7, and filter holes 8 into a suitable position. When the water carrying debris first contacts the filter slope 7, the water seeps downwards through the filter holes 8, while the debris remaining on the surface rolls off the filter slope to the adjacent area, avoiding secondary clogging caused by its accumulation. Furthermore, the entire structure is easy to disassemble and assemble, facilitating regular cleaning.

It is a large-volume box-shaped structure, facilitating the installation of the filter components while also slowing the water flow for easier treatment. The sliding slot 2, a T-shaped slot with a baffle at the bottom, acts as the connecting component. The side-connected clamping plate 3 secures the external components, and the positioning hole 4 on it provides positioning. This configuration creates a component for precise positioning and installation, giving the anti-clogging filter components a degree of installation freedom.

The positioning bolts 5 are easy to install and remove, which reduces a lot of labor during subsequent periodic cleaning. The connecting rod 6, as a connecting rod-shaped component, has a filter slope 7 fixedly connected to its side surface, which plays the main role of preventing clogging. The filter slope 7 itself is a sloped object with multiple filter holes 8.
