Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0023] Example 1: Please refer to Figures 1-6The present invention provides a technical solution: a drainage pipe filter and anti-clogging structure for highway maintenance, including a first pipe 1, a first filter mechanism 3 fixedly connected to the top of the first pipe 1, a second pipe 2 fixedly connected inside the first pipe 1, and a first anti-clogging mechanism 4 fixedly connected inside the second pipe 2. Drainage pipes (especially in highway maintenance scenarios) are core facilities for ensuring road traffic safety and smooth urban drainage, but they have long faced the problem of clogging caused by complex impurities. In daily drainage, sewage carrying silt and domestic waste easily accumulates in pipes. During rainy days, rainwater washes away road surface gravel, fallen leaves, and large debris, causing a sudden increase in the amount of impurities in the pipes. Existing pipe filtration solutions mostly only have basic single filtration functions and lack a graded interception and continuous protection mechanism for the complex impurities in highway scenarios. Traditional single-stage filtration structures can only target a certain type of particle size impurities. If a large-pore filter screen is used, small particles will directly enter the downstream pipe and accumulate and clog for a long time. If a small-pore filter screen is used, large particles will easily clog the filter screen instantly, causing drainage interruption. Traditional single-stage filtration has poor adaptability to the mixed impurities of large and small particles in highway drainage pipes. Large particles are prone to instantaneous blockage, while small particles are prone to long-term accumulation and blockage. The first filtration mechanism 3 and the second filtration mechanism 5 are set up. The first filtration mechanism undertakes the primary interception and active unclogging functions. Its conical filter cylinder 35 can prioritize the interception of large particles and prevent large particles from clogging the pipes. The first filter instantly blocks the downstream filtration components; simultaneously, in conjunction with the drive and anti-clogging components, the filter cartridge holes are periodically cleaned by a soft brush, and the rotating drum temporarily stores impurities, reducing the downstream filtration pressure from the source. The second filtration mechanism 5 undertakes secondary fine filtration and residual cleaning functions. The dual filter discs intercept mud, sand, and fine stone chips missed by the primary filtration through small-diameter holes, making up for the pore size blind spots of the single-stage filtration. The drive component can also drive the filter discs to move relative to each other, using cleaning blocks to remove impurities stuck in the holes, and then linking the anti-clogging mechanism to vibrate the filter discs, shaking off and collecting the residual impurities. The two work together to ensure that the drainage pipe can work normally and continuously. The top of the second pipe 2 is fixedly connected to the second anti-clogging mechanism 6, and the second filtration mechanism 5 is slidably connected inside the second pipe 2. The primary filtration core of the highway drainage pipe relies on the conical filter cartridge, which must first intercept large particles of impurities in the sewage to prevent large particles from entering the downstream fine filtration components and causing instantaneous blockage.However, large particles of impurities easily get stuck in the through-holes of the conical filter cartridge. They cannot be dislodged by water flow alone, and long-term accumulation will gradually clog the filter holes, significantly reducing the primary filtration efficiency. Existing primary anti-clogging solutions have obvious shortcomings: First, passive cleaning has limited effectiveness, relying mostly on simple backwashing, which can only remove loose surface impurities and is ineffective against stubborn particles stuck in the through-holes; second, there is a lack of a closed-loop impurity collection system, so cleaned impurities easily accumulate around the filter cartridge and clog the through-holes again with the water flow, forming secondary clogging; third, there is no adaptive linkage design, and the anti-clogging structure is not integrated with the filter cartridge rotation function, so the anti-clogging action is not synchronized with the filtration process. The disconnect prevents simultaneous handling of clogging issues. To address this, a first anti-clogging mechanism 4 and a second anti-clogging mechanism 6 are implemented for proactive clogging removal. These mechanisms are linked to the first filtration mechanism's drive system. Through components such as a limit rotating ring and a soft brush, the soft brush moves periodically back and forth along the filter cylinder, scraping away clogging particles in real time, effectively delaying clogging and creating a closed-loop collection system. The system guides the slider to collect impurities, and with the collision of the ball block and spring vibration, impurities are accelerated into the collection components, cutting off secondary clogging paths and preventing secondary adhesion. Finally, a third drive motor 61 drives the filter disc to vibrate back and forth, shaking off residual impurities to be collected in the second housing 68. The first anti-blocking mechanism 4 includes: The limiting rotation ring block 42 is fixedly connected to the surface of the gear disk 33. The second fixing block 43 is slidably connected to the surface of the first limiting rod 44; The second filter disc 52 is slidably connected inside the second pipe 2.

[0024] The first filtration mechanism 3 includes a first drive motor 31, which is fixedly connected to the top of the first pipe 1. A cylindrical gear 32 is fixedly connected inside the first drive motor 31 through an output shaft. A gear disk 33 is rotatably connected inside the first pipe 1, and the surface of the cylindrical gear 32 meshes with the surface of the gear disk 33. A rotating roller 34 is fixedly connected inside the gear disk 33.

[0025] The rotating drum 34 has a threaded groove inside, and a conical filter cylinder 35 is fixedly connected to the right side surface of the rotating drum 34. The surface of the conical filter cylinder 35 has a through hole.

[0026] The first anti-blocking mechanism 4 also includes a first fixing block 41, which is fixedly connected inside the second pipe 2 and rotatably connected to the conical filter cylinder 35. A first limiting rod 44 is fixedly connected to the surface of the first fixing block 41, and a first spring 4401 is fixedly connected to the surface of the first limiting rod 44.

[0027] The top of the second fixing block 43 is rotatably connected to a rotating ball bearing 412, and the bottom of the second fixing block 43 is fixedly connected to a soft brush 4301.

[0028] The first fixing block 41 is internally fixedly connected to a second limiting rod 413. The surface of the second limiting rod 413 is slidably connected to a guide slider 46. The two ends of the guide slider 46 are fixedly connected to a second spring 45, and the second spring 45 is slidably connected to the second limiting rod 413 and fixedly connected to the first fixing block 41.

[0029] The bottom of the first pipe 1 is fixedly connected to a first housing 49, the inside of the first housing 49 is rotatably connected to a first rotating screw 48, the top of the first rotating screw 48 is fixedly connected to a first arc-shaped plate 47, and the first housing 49 is located on the left side of the rotating roller 34.

[0030] In use, wastewater flows through the first pipe 1 and the second pipe 2. When cleaning the filter mechanism inside the first pipe 1, the wastewater flow is stopped, and then the first drive motor 31 is started. The start of the first drive motor 31 drives the cylindrical gear 32 to rotate through the output shaft. The rotation of the cylindrical gear 32 drives the gear disc 33 to rotate, which in turn drives the rotating drum 34 to rotate. The rotation of the rotating drum 34 drives the conical filter cylinder 35 to rotate together. At the same time as the gear disc 33 rotates, it also drives the limiting rotating ring block 42 to rotate. The rotation of the limiting rotating ring block 42 causes the second fixed block 43 to move up and down on the surface of the first limiting rod 44 under the action of the first spring 4401. The up and down movement of the second fixed block 43 drives the soft brush 4301 at its bottom to move back and forth, so that the soft brush 4301 periodically cleans the through hole opened in the conical filter cylinder 35, cleaning the impurities into the interior of the guide slider 46. Under the action of gravity, the impurities slide towards the bottom of the guide slider 46 and finally slide into the interior of the rotating drum 34, thus timely cleaning. The impurities are collected to prevent further clogging of the through holes of the conical filter cylinder 35. As the conical filter cylinder 35 rotates, it drives the second ball block 411 fixed inside to rotate as well. At this time, the second ball block 411 will periodically collide with the first ball block 410. The periodic collision between the second ball block 411 and the first ball block 410 will cause the guide slider 46 to vibrate periodically through the setting of the second spring 45, thereby further accelerating the sliding speed of impurities inside the guide slider 46 and preventing impurities from accumulating on the surface of the guide slider 46. After the impurities fall into the interior of the rotating drum 34, the first rotating screw 48 is rotated. The rotation of the first rotating screw 48 drives the first arc plate 47 to move towards the bottom of the first box 49, so that the impurities fall into the interior of the first box 49. Through the threaded groove set inside the rotating drum 34, the impurities eventually fall into the interior of the first box 49 along with the threaded groove during the rotation of the rotating drum 34, which facilitates the subsequent centralized cleaning of impurities.

[0031] The conical filter cylinder 35 is used for initial filtration of sewage, and the first filter disc 51 and the second filter disc 52 are used for secondary filtration of sewage. This avoids the situation where a single filter screen is easily blocked by large particles of impurities, reduces the pressure of subsequent filtration, and ensures that the drain pipe can work normally and continuously. A limiting rotating ring block 42 is set up. The first drive motor 31 is started and drives the limiting rotating ring block 42 to rotate through gear meshing. At this time, the rotating ball 412 continuously slides on the surface of the limiting rotating ring block 42. With the help of the first spring 4401, the second fixed block 43 moves back and forth periodically, which finally causes the soft brush 4301 to clean the through hole of the conical filter cylinder 35 and prevent the through hole from being blocked.

[0032] By setting a guide slider 46, the soft brush 4301 cleans the impurities falling from the through holes of the conical filter cylinder 35, which fall into the interior of the guide slider 46 and eventually slide into the interior of the rotating drum 34. This timely collection of the cleaned impurities prevents them from further clogging the through holes of the conical filter cylinder 35. Furthermore, the first ball block 410 and the second ball block 411 are set in conjunction. When the conical filter cylinder 35 rotates, the first ball block 410 periodically collides with the second ball block 411, thereby causing the guide slider 46 to vibrate periodically. This ensures that the cleaned impurities are collected quickly while preventing impurities from accumulating inside the guide slider 46 and affecting subsequent normal drainage.

[0033] Example 2: Please refer to Figures 1-8 Based on Embodiment 1, the present invention provides a technical solution: A second drive motor 53 is fixedly connected to the surface of the second filter disc 52. A second rotating threaded rod 54 is fixedly connected to the inside of the second drive motor 53 through an output shaft. A first filter disc 51 is slidably connected to the surface of the second rotating threaded rod 54.

[0034] The surface of the second filter disc 52 has through holes, and the surface of the second filter disc 52 is fixedly connected to the second cleaning block 5201. The surface of the first filter disc 51 also has through holes, and the surface of the first filter disc 51 is fixedly connected to the first cleaning block 501. The second filter disc 52 is fixedly connected to the second rotating threaded rod 54.

[0035] The second anti-clogging mechanism 6 includes a third fixing block 62, which is fixedly connected to the top of the second pipe 2. A third drive motor 61 is fixedly connected to the surface of the third fixing block 62. A rotating disk 64 is fixedly connected to the inside of the third drive motor 61 through an output shaft. A rotating toothed block 63 is rotatably connected to the surface of the third fixing block 62, and the rotating disk 64 and the rotating toothed block 63 are slidably connected. A connecting bracket 65 is slidably connected to the inside of the second pipe 2, and the surface of the rotating toothed block 63 is meshed with the connecting bracket 65. The connecting bracket 65 is fixedly connected to the second filter disc 52. A second housing 68 is fixedly connected to the bottom of the second pipe 2. A third rotating threaded rod 67 is rotatably connected to the inside of the second housing 68. A second arc-shaped plate 66 is fixedly connected to the top of the third rotating threaded rod 67.

[0036] In use, when cleaning the filter mechanism inside the second pipe 2, firstly rotate the third rotating threaded rod 67. The rotation of the third rotating threaded rod 67 drives the second arc-shaped plate 66 to move towards the bottom of the second housing 68. Then, start the second drive motor 53. The start of the second drive motor 53 drives the second rotating threaded rod 54 to rotate through the output shaft. The rotation of the second rotating threaded rod 54 drives the first filter disc 51 to move towards the location of the second filter disc 52. Finally, the first cleaning block 501 cleans the impurities in the through holes of the second filter disc 52, and the second cleaning block 5201 cleans the impurities in the through holes of the first filter disc 51. Then, start the third drive motor 61. The start of the third drive motor 61 drives the rotating disk 64 to rotate through the output shaft. The rotation of the rotating disk 64 drives the rotating toothed block 63 to rotate on the third fixed block 6. The surface of the second pipe 2 rotates back and forth. The reciprocating rotation of the rotating toothed block 63 drives the connecting bracket 65 to move back and forth inside the second pipe 2. The reciprocating movement of the connecting bracket 65 drives the second filter disc 52 to vibrate back and forth. The vibration of the second filter disc 52 drives the first filter disc 51 to vibrate continuously, so that all the cleaned impurities slide down into the interior of the second housing 68, which facilitates the subsequent centralized cleaning of impurities and prevents the impurities cleaned by the first cleaning block 501 and the second cleaning block 5201 from sticking to the surface of the first filter disc 51 and the second filter disc 52. This ensures that the impurities are completely collected. The first housing 49 and the second housing 68 are set up to facilitate the timely collection of the cleaned impurities, so that the through holes of the filter mechanism always remain open and avoid secondary blockage caused by untimely collection of impurities.

[0037] By setting a first cleaning block 501 on the surface of the first filter disc 51 and a second cleaning block 5201 on the surface of the second filter disc 52, the second drive motor 53 is started to drive the second rotating threaded rod 54 to rotate, thereby moving the first filter disc 51 towards the direction of the second filter disc 52, thus cleaning the through holes of the first filter disc 51 and the second filter disc 52, preventing impurities from clogging the second filter disc 52 and the first filter disc 51. Furthermore, a connecting bracket 65 is set, and the third drive motor 61 is started to drive the connecting bracket 65 to move back and forth, thereby causing the second filter disc 52 and the first filter disc 51 to vibrate continuously, preventing impurities cleaned by the first cleaning block 501 and the second cleaning block 5201 from sticking to the surface of the first filter disc 51 and the second filter disc 52, ensuring that impurities are completely collected.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
