Description

Technical Field

[0001] This utility model relates to the field of anti-clogging device technology, specifically, to an anti-clogging device for drainage pipes. Background Technology

[0002] Drainage pipes are pipe systems used to collect and transport domestic sewage, industrial wastewater, or rainwater. They are a core component of building drainage and municipal infrastructure. For municipal pipes, rainwater contains mud, sand, branches, plastic bags, and other organic matter during rain. When draining, rainwater will carry impurities through the pipes. Therefore, grates are usually installed inside the pipes or between two pipes to intercept garbage or impurities and accumulate them in one place, preventing garbage and impurities from clogging the pipes.

[0003] When impurities come into contact with the screen, the screen blocks the impurities, and the water source continues to flow through the pipe through the screen. At this time, the impurities accumulate on the side of the screen. If more impurities are blocked later, the impurities will accumulate more and more on the side of the screen, which may eventually block the screen and affect the flow of water. If the impurities are collected and cleaned manually, the device needs to be opened more often to clean the internal debris, which is also quite troublesome. Utility Model Content

[0004] To overcome the above-mentioned defects, the present invention provides an anti-clogging device for drainage pipes, which solves the technical problem in the prior art that impurities easily accumulate on the side of the grating, thus easily clogging the side of the grating.

[0005] According to one aspect, at least one embodiment of the present invention provides an anti-clogging device for drainage pipes, including a grating, a connecting box, a cleaning plate, an arc-shaped plate, and a rotating scraping assembly. The grating is installed inside the connecting box, and circular holes for connecting pipes are opened on both sides of the connecting box. The cleaning plate is slidably installed inside the connecting box through a lifting assembly. Two arc-shaped plates are provided, and the two arc-shaped plates are respectively fixedly installed on both sides of the cleaning plate, and the arc-shaped plates penetrate the top of the connecting box. The rotating scraping assembly is disposed on the lifting assembly and is used to rotate the cleaning plate to scrape impurities on the side of the grating to one side.

[0006] Furthermore, the lifting assembly includes a support cover, a reciprocating screw, a lifting rod, and a first throttle. The support cover is fixedly installed on the side of the communicating box. The reciprocating screw is rotatably installed inside the support cover, and a matching crescent-shaped slider is installed on the reciprocating screw. One end of the lifting rod is fixedly installed on the side of the crescent-shaped slider. The first throttle is coaxially connected to the reciprocating screw.

[0007] Furthermore, the rotating scraping assembly includes a rotating ring, a rotating plate, a rotating shaft, a second rotary handle, and a positioning component. The side of the rotating ring is fixedly installed on the side of the lifting rod, and a circular groove is formed on the inner side wall of the rotating ring. The rotating plate is slidably installed in the circular groove of the rotating ring. The rotating shaft is rotatably installed through the rotating plate, and the bottom end of the rotating shaft is fixedly connected to the top end of the scraping plate. The second rotary handle is coaxially connected to the rotating shaft, and the positioning component is disposed on the rotating ring.

[0008] Furthermore, the positioning component includes a positioning frame and a positioning rod. The positioning frame is fixedly installed on the top of the rotating plate, and the positioning rod is fixedly installed on the top of the rotating ring. The top of the positioning rod has an L-shaped groove that fits against the side of the positioning frame.

[0009] Furthermore, when the side of the positioning frame is in contact with the L-shaped groove of the positioning rod, the cleaning plate and the top of the connecting box are in a vertical position.

[0010] Furthermore, fixing rods are fixedly installed on both sides of the rotating ring, and when the bottom end of the fixing rod contacts the top end of the connecting box, the bottom end of the cleaning plate contacts the inner bottom end of the connecting box.

[0011] Furthermore, a limiting groove is formed on the inner side wall of the support cover, and a limiting block is slidably installed in the limiting groove, with the side of the limiting block being fixedly connected to the side of the crescent-shaped slider.

[0012] Furthermore, the side of the connecting box is provided with a waste discharge groove, and a box cover is hinged to the waste discharge groove.

[0013] The beneficial effects of this utility model are as follows: In this invention, when the pipeline is draining water, impurities are blocked by the grating, allowing the water to flow out. When a large amount of impurities accumulate on the side of the grating, the lifting assembly can move the cleaning plate and the arc plate into the interior of the connecting box. Then, the workers can rotate the cleaning assembly to make the cleaning plate and the arc plate rotate inside the connecting box, thereby scraping the impurities accumulated on the side of the grating to both sides of the connecting box. This allows the middle part of the side of the grating to be cleaned out, so that the water will not be blocked by a large amount of impurities after it flows through. Attached Figure Description

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-7 As shown, this invention illustrates an anti-clogging device for drainage pipes according to one embodiment of the present invention. The device includes a grille 1, a connecting box 2, a cleaning plate 3, an arc-shaped plate 4, and a rotating scraping assembly. The grille 1 is installed inside the connecting box 2, and circular holes for connecting pipes are provided on both sides of the connecting box 2. The cleaning plate 3 is slidably installed inside the connecting box 2 through a lifting assembly. Two arc-shaped plates 4 are provided, each fixedly installed on both sides of the cleaning plate 3, and the arc-shaped plates 4 penetrate the top of the connecting box 2. The rotating scraping assembly is mounted on the lifting assembly and is used to rotate the cleaning plate 3 to scrape impurities from the sides of the grille 1 to one side.

[0024] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, during installation, two pipes are installed through flanges at the round holes on both sides of the connecting box 2. When water flows through one of the pipes, it passes through the connecting box 2. The screen 1 can block impurities in the water source. The water source then flows out through the screen 1. After the water source flows through the screen multiple times, a lot of impurities accumulate on the side of the screen 1. The lifting assembly can then move the cleaning plate 3 and the arc plate 4 down into the connecting box 2. The lifting assembly includes a support cover 5, a reciprocating screw 6, a lifting rod 8, and a first throttle 9. The support cover 5 is fixedly installed on the side of the connecting box 2. The reciprocating screw 6 is rotatably installed inside the support cover 5, and a matching crescent-shaped slider 7 is installed on the reciprocating screw 6. One end of the lifting rod 8 is fixedly installed on the side of the crescent-shaped slider 7. The first throttle 9 is coaxially connected to the reciprocating screw 6.

[0025] Specifically, the worker descends to the pipe on the ground and then turns the first handle 9. The first handle 9 drives the reciprocating screw 6 to rotate within the support cover 5. The crescent-shaped slider 7 drives the lifting rod 8 to move downwards, which in turn drives the rotating ring 10 to move downwards, simultaneously driving the cleaning plate 3 and the arc-shaped plate 4 to move downwards. Because the rotating ring 10 is fixedly installed with fixing rods 17 on both sides, and when the bottom end of the fixing rod 17 contacts the top of the connecting box 2, the bottom end of the cleaning plate 3 contacts the inner bottom end of the connecting box 2. After the fixing rod 17 contacts the top of the connecting box 2, the crescent-shaped slider 7 stops moving downwards. At this time, the cleaning plate 3 and the arc-shaped plate 4 contact the inner bottom end of the connecting box 2, and most of the impurities are located in the cleaning area. Regarding the side of the miscellaneous plate 3, it should be noted that the shape design of the crescent-shaped slider 7 matches the helical groove of the reciprocating screw 6. When the reciprocating screw 6 rotates, the side wall of the helical groove will generate an axial thrust on the crescent-shaped slider 7 embedded therein. The inner side wall of the support cover 5 has a limit groove, and a limit block is slidably installed in the limit groove. The side of the limit block is fixedly connected to the side of the crescent-shaped slider 7. Thus, the crescent-shaped slider 7 can only move along the axial trajectory of the reciprocating screw 6, thereby moving up and down. When the crescent-shaped slider 7 reaches the end of the reciprocating screw 6, the crescent-shaped slider 7102 will smoothly transition to the reverse helical groove, thereby realizing reciprocating movement. This is a well-known technology and will not be described in detail here.

[0026] like Figure 6 and Figure 7As shown, after the movement is completed, the rotating scraper assembly drives the cleaning plate 3 and the arc plate 4 to rotate, thereby scraping the impurities on the side of the cleaning plate 3 to a position near the inside of the connecting box 2, thus "opening" the middle part to facilitate the subsequent flow of water without being blocked by impurities. The rotating scraper assembly includes a rotating ring 10, a rotating plate 11, a rotating shaft 12, a second handle 13, and a positioning assembly. The side of the rotating ring 10 is fixedly installed on the side of the lifting rod 8, and the inner side wall of the rotating ring 10 is provided with a circular groove. The rotating plate 11 slides... The rotating shaft 12 is rotatably mounted on the rotating plate 11 through the rotating ring 10, and the bottom end of the rotating shaft 12 is fixedly connected to the top end of the cleaning plate 3. The second handle 13 is coaxially connected to the rotating shaft 12. The positioning assembly is set on the rotating ring 10. The positioning assembly includes a positioning frame 14 and a positioning rod 15. The positioning frame 14 is fixedly mounted on the top end of the rotating plate 11, and the positioning rod 15 is fixedly mounted on the top end of the rotating ring 10. The top end of the positioning rod 15 is provided with an L-shaped groove that fits against the side of the positioning frame 14.

[0027] Specifically, after the cleaning plate 3 contacts the inner bottom of the connecting box 2, the operator rotates the second handle 13. The second handle 13 drives the rotating shaft 12 to rotate, which in turn drives the cleaning plate 3 and the arc plate 4 to rotate. This scrapes away the impurities accumulated next to the grid 1. The two arc plates 4 are placed opposite each other on the sides of the cleaning plate 3, which scrapes away the impurities on both sides of the cleaning plate 3. At this time, most of the impurities are located between the cleaning plate 3 and the grid 1. If there are a few impurities on the other side of the cleaning plate 3, they can also be scraped and moved to the other side. The arc shape of the arc plate 4 also makes the scraping of impurities more effective. After scraping is completed, the cleaning plate 3 is rotated in the opposite direction. When the side of the positioning frame 14 is in contact with the L-shaped groove of the positioning rod 15, the cleaning plate 3 and the top of the connecting box 2 are in a vertical position. The frame 14 is blocked by the L-shaped groove of the positioning rod 15 and cannot continue to rotate. At this time, when the cleaning plate 3 rises, it can pass through the connecting box 2 and let it out. Then, the operator turns the first handle 9 so that the cleaning plate 3 and the arc plate 4 pass through the top of the connecting box 2 and move it out. During the movement, one-third of the cleaning plate 3 and the arc plate 4 can be left in the connecting box 2, thus sealing the top of the connecting box 2 and preventing the water from being blocked by the cleaning plate 3 inside when it flows through the connecting box 2. After scraping the impurities repeatedly, the impurities accumulate more and more in the connecting box 2. Because the side of the connecting box 2 has an outlet groove and the outlet groove is hinged with a box cover 16, the operator can open the box cover 16 and periodically clean out the impurities in the connecting box 2. The box cover 16 is equipped with a lock to lock the box cover 16.

[0028] Working principle: When cleaning the accumulated impurities on the side of the grille 1, the worker goes down to the pipe on the ground and turns the first handle 9. The first handle 9 drives the reciprocating screw 6 to rotate inside the support cover 5. The crescent slider 7 drives the lifting rod 8 to move down, and the lifting rod 8 drives the rotating ring 10 to move down, simultaneously driving the cleaning plate 3 and the arc plate 4 to move down. After the fixed rod 17 contacts the top of the connecting box 2, the crescent slider 7 stops moving down. At this time, the cleaning plate 3 and the arc plate 4 contact the inner bottom of the connecting box 2. At this time, most of the impurities are located on the side of the cleaning plate 3. Then the worker turns the second handle 13. The second handle 13 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the cleaning plate 3 and the arc plate 4 to move down. The rotating plate 4 scrapes away the impurities accumulated next to the grid 1. The two arc-shaped plates 4 are placed opposite each other on the sides of the cleaning plate 3, which scrapes away the impurities on both sides of the cleaning plate 3. After scraping, the cleaning plate 3 is rotated in the opposite direction until the positioning frame 14 is blocked by the L-shaped groove of the positioning rod 15 and cannot continue to rotate. At this time, the cleaning plate 3 rises and passes through the connecting box 2, allowing it to go out. Then, the operator turns the first handle 9 to make the cleaning plate 3 and the arc-shaped plate 4 pass through the top of the connecting box 2 and move it out. When there are many impurities inside the connecting box 2, the operator can open the box cover 16 and clean out the impurities inside the connecting box 2 periodically.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
