[0006] By adopting the above technical scheme, when the sewage pipe body is used for sewage discharge, the sewage first enters the inner cavity of the sewage pipe body through the water inlet, and then flows out of the water outlet through the gap between the plurality of movable blocks and the plurality of baffle plates. After the sewage pipe body is used for sewage discharge for a specified time, the driving mechanism is started, and the driving mechanism drives the movable blocks to rotate along the circumference of the movable rod. The change of the position of the movable blocks changes the flow path of the sewage in the sewage pipe body. In this way, the driving mechanism is started at the specified time node, the single flow path of the sewage in the sewage pipe body is changed, the risk of blockage of the flow path of the sewage in the sewage pipe body is reduced, and the end cover is detachably connected to the pipe opening of the sewage pipe body. The end of the movable rod is detachably connected to the end cover. Subsequently, when cleaning the impurities in the sewage pipe body, the end cover is separated from the sewage pipe body, and then the movable rod is separated from the end cover. The movable rod can be pulled out of the pipe cavity of the sewage pipe body. With the movement of the movable rod, the impurities attached to the inner wall of the sewage pipe body are scraped out of the sewage pipe body by the movable blocks and the baffle plates, thereby completing the cleaning work of the impurities in the sewage pipe body, and further improving the problem that a large amount of time and cost is required to dredge the sewage pipe due to internal blockage.

After the first scraper block and the second scraper block abut against each other, the impurities will be received in the closed chamber formed between the first scraper block, the second scraper block and the baffle, realizing the effect of packing the impurities in the drain pipe body. The contact between the packed impurities and the sewage in the drain pipe body is reduced.

Through the engagement transmission of the gear ring, when the load of the first shovel block and the second shovel block changes, the risk of poor rotation of the first shovel block and the second shovel block is reduced, the effect of smooth transmission is realized, and the problem of difficult rotation of the first shovel block and the second shovel block when the sewage flows in the drain pipe body is improved.

[0017] Optionally, the gear ring is provided with a plurality of groups, and the plurality of groups of gear rings are arranged along the axial direction of the movable rod.

[0038] The following will be described in detail in combination with the accompanying Figures 1-8 The present application is further described in detail.

[0039] The embodiments of the present application disclose a drain pipe structure with anti-clogging function to improve the problem that a large amount of time and cost need to be spent for dredging due to internal clogging of the drain pipe.

[0040] Embodiment 1

[0041] With reference to Figure 1 and Figure 2 A drain pipe structure with anti-clogging function includes a drain pipe body 1, a movable rod 2, a plurality of baffles 3, a plurality of movable blocks 4, and a driving mechanism 5. The projection of the drain pipe body 1 along its own axis is circular. The movable rod 2 is coaxially arranged in the pipe cavity of the drain pipe body 1. The side walls of the baffles 3 and the movable blocks 4 abut the inner cavity of the drain pipe body 1. The plurality of baffles 3 and the plurality of movable blocks 4 are arranged along the axis of the movable rod 2 and are arranged in a staggered manner. The baffles 3 in semicircular structure are fixed to the side wall of the movable rod 2, and the movable blocks 4 are rotationally connected to the side wall of the movable rod 2. The driving mechanism 5 is used to drive the movable blocks 4 to rotate. The rotating movable blocks 4 are used in combination with the baffles 3 to change the single flow path of sewage in the drain pipe body 1, thereby improving the problem that a large amount of time and cost need to be spent for dredging due to internal clogging of the drain pipe.

[0042] With reference toFigure 2 And Figure 3 Specifically, the end cover 6 is detachably connected to the pipe opening at each end of the drain pipe body 1, and the end cover 6 is used to cover the pipe opening of the drain pipe body 1. The connection between the end cover 6 and the drain pipe body 1 can be flange connection or threaded connection. The side wall at each end of the drain pipe body 1 is provided with a water inlet 11 and a water outlet 12, respectively, to allow sewage to enter and exit the lumen of the drain pipe body 1. The end of the movable rod 2 is detachably connected to the end cover 6, and the detachable connection between the movable rod 2 and the end cover 6 can be flange connection or threaded connection. By this design, it is convenient to subsequently pull the movable rod 2 out of the lumen of the drain pipe body 1, so as to use the movable block 4 and the baffle 3 to scrape the impurities in the lumen of the drain pipe body 1 out of the lumen of the drain pipe body 1.

[0043] Referring to Figure 4 And Figure 5 The movable block 4 includes a first scraper 41 and a second scraper 42, wherein the first scraper 41 and the second scraper 42 are both rotationally connected to the side wall of the movable rod 2. It is worth noting that the first scraper 41 and the second scraper 42 are the same in structure, but different in position. For the convenience of understanding, the projection of the first scraper 41 along the axis of the movable rod 2 is a quarter of a circle; when the movable block 4 is not rotated, the first scraper 41 and the second scraper 42 abut each other, and the projection of the movable block 4 along the axis of the drain pipe body 1 is a semicircle; when the movable block 4 is rotated, the first scraper 41 and the second scraper 42 rotate and abut each other, and the projection of the movable block 4 along the axis of the drain pipe body 1 is also a semicircle, but the positions of the first scraper 41 and the second scraper 42 have changed.

[0044] Referring to Figure 3 And Figure 4 The side wall of the first scraper 41 is provided with a first receiving groove 411, and the first receiving groove 411 extends along the axis of the movable rod 2. One end of the first receiving groove 411 penetrates the side wall of the first scraper 41 to form a first notch 412. The side wall of the second scraper 42 is provided with a second receiving groove 421, and the second receiving groove 421 extends along the axis of the movable rod 2. One end of the second receiving groove 421 penetrates the side wall of the second scraper 42 to form a second notch 422. When the sewage flows into the lumen of the drain pipe body 1 through the water inlet 11, the sewage flows into the first receiving groove 411 and the second receiving groove 421, and then enters the gap between the movable block 4 and the baffle 3, and the sewage continues to flow along the axis of the drain pipe body 1 and then flows out of the water outlet 12.

[0045] Referring to Figure 4 And Figure 5, the first shovel block 41 is integrally formed with a first sawtooth groove 413 at the edge of the slot opening of the first receiving groove 411, and the first sawtooth groove 413 is arranged along the circumferential direction of the slot opening of the first receiving groove 411. The second shovel block 42 is integrally formed with a second sawtooth groove 423 at the edge of the slot opening of the second receiving groove 421, and the second sawtooth groove 423 is arranged along the circumferential direction of the slot opening of the second receiving groove 421.

[0046] Referring to Figure 3 and Figure 4 , the slot wall of the first receiving groove 411 and the slot wall of the second receiving groove 421 are both provided with a plurality of filter holes 43. The slot wall of the first receiving groove 411 and the slot wall of the second receiving groove 421 are both integrally formed with a plurality of intercepting protrusions 44, and gaps are left between adjacent intercepting protrusions 44. When the driving mechanism 5 drives the first shovel block 41 and the second shovel block 42 to rotate, the rotation of the first shovel block 41 and the second shovel block 42 respectively removes the impurities attached to the inner wall of the drain pipe body 1 into the first receiving groove 411 and the second receiving groove 421. With the continuous rotation of the first shovel block 41 and the second shovel block 42, the slot opening of the first receiving groove 411 and the slot opening of the second receiving groove 421 will be opposite and abut, the first sawtooth groove 413 will be engaged with the second sawtooth groove 423, the flap 3 will cover the first gap 412 and the second gap 422, and the impurities will be contained in the closed chamber formed between the first shovel block 41, the second shovel block 42 and the flap 3, realizing the effect of packing the impurities in the drain pipe body 1, and through the filter holes 43, the water contained in the impurities in the closed chamber is drained, improving the problem that the sewage drops around the drain pipe body 1 after the movable rod 2 is pulled out of the drain pipe body 1.

[0047] Referring to Figure 3 and Figure 4 , the driving mechanism 5 includes two rotating rods 51 and a plurality of gear rings 52. The inside of the movable rod 2 is provided with a movable cavity 21, and the movable cavity 21 is arranged along the axial direction of the movable rod 2. The two rotating rods 51 are both rotatably arranged in the movable cavity 21. The surface of the end cover 6 is provided with a driving hole 61, and the driving hole 61 is rotatably arranged in the rotating rod 51. The gear ring 52 is coaxially fixed to the circumferential side of the rotating rod 51, the gear rings 52 on the circumferential sides of the two rotating rods 51 are engaged with each other, and a plurality of gear rings 52 are arranged along the axial direction of the movable rod 2.

[0048] Referring to Figure 3 and Figure 4The periphery of the movable rod 2 is provided with a plurality of movable holes 22 corresponding to the plurality of movable blocks 4. The movable holes 22 extend along the circumference of the movable rod 2. The first and second shovel blocks 41 and 42 are respectively fixed to the periphery of the two rotating rods 51, so that when the rotating rods 51 are driven to rotate, the first and second shovel blocks 41 and 42 are connected to the periphery of the movable rod 2 through the movable holes 22. In other embodiments, the end cover 6 is bolted with a rotating motor, and the rotating shaft of the rotating motor is connected with the rotating rod 51 through a coupling, so as to improve the rotating efficiency of the rotating rod 51.

[0049] The implementation principle of the embodiment 1 is that when the drain pipe body 1 is used for sewage discharge, the sewage enters the inner cavity of the drain pipe body 1 through the water inlet 11, and then flows out of the water outlet 12 through the gap between the movable blocks 4 and the blocking pieces 3. After the sewage is discharged through the drain pipe body 1 for a specified time, the rotating rod 51 is rotated, and the first and second shovel blocks 41 and 42 rotate along the circumference of the movable rod 2. After the first and second shovel blocks 41 and 42 abut against each other, the impurities are collected in the closed chamber formed between the first and second shovel blocks 41 and 42 and the blocking pieces 3, which not only realizes the effect of packing the impurities in the drain pipe body 1, but also changes the single flow path of the sewage in the drain pipe body 1. Subsequently, when the impurities in the drain pipe body 1 are cleaned, the end cover 6 is separated from the drain pipe body 1, and then the movable rod 2 is separated from the end cover 6. The movable rod 2 can be pulled out of the pipe cavity of the drain pipe body 1. With the movement of the movable rod 2, the impurities adhering to the inner wall of the drain pipe body 1 are scraped out of the drain pipe body 1 by the movable blocks 4 and the blocking pieces 3, so that the cleaning work of the impurities in the drain pipe body 1 is completed, and the problem of subsequent time and cost spent for dredging caused by the blockage of the drain pipe is improved.

The elastic member 53 can be a tension spring, a spring rope or a torsion spring, and the two ends of the elastic member 53 are respectively fixed to the inner walls of the first and second receiving grooves 411 and 421. The elastic member 53 is used to force the first shovel block 41 to be opposite to the slot of the second insertion block 54.

[0052] Referring to Figure 7 and Figure 8The plug 54 has a slot 541, and the first gap 412 and the second gap 422 are both provided for the plug 54 to pass through, and the slot 541 is used to accommodate the slot wall of the first receiving groove 411 and the slot wall of the second receiving groove 421. The inner wall of the slot 541 is adhesively fixed with a non-slip pad 7, and the non-slip pad 7 is used to abut against the slot wall of the first receiving groove 411 and the slot wall of the second receiving groove 421. It can be understood that when the slot wall of the first receiving groove 411 and the slot wall of the second receiving groove 421 are located in the slot 541, the plug 54 fixes the elastic deformation state of the elastic member 53.

[0053] Referring to Figure 7 and Figure 8 , the inner part of the movable rod 2 is provided with a rod cavity 23 extending along the axial direction of the movable rod 2, and the connecting rod 55 is rotatably arranged in the rod cavity 23. The surface of the end cover 6 is provided with a rod hole 62, and the rod hole 62 is used for the connecting rod 55 to rotatably pass through. The side wall of the movable rod 2 is provided with a plurality of rope holes 24 corresponding to the plurality of plug blocks 54. The side wall of the connecting rod 55 is fixed with a plurality of supporting ropes 57 corresponding to the plurality of rope holes 24, and the rope holes 24 are used for the supporting ropes 57 to pass through. The plug block 54 is fixed to the end of the supporting rope 57 away from the connecting rod 55, and the connecting rod 55 is used to wind the supporting rope 57 to force the plug block 54 to separate from the movable block 4.

[0054] Referring to Figure 8 , the driving motor 56 is bolted to the surface of the end cover 6, and the driving motor 56 is connected to the end of the connecting rod 55 through a shaft coupling, so as to improve the efficiency of the connecting rod 55 in winding the supporting rope 57 by using the driving motor 56.

[0055] The implementation principle of the embodiment 2 is that when the sewage flows in the drain pipe body 1, the elastic member 53 is in an elastic deformation state, and the slot wall of the first receiving groove 411 and the slot wall of the second receiving groove 421 are located in the slot 541 of the plug block 54 to fix the elastic deformation state of the elastic member 53. When the driving motor 56 is started, the connecting rod 55 rotates and winds the supporting rope 57, and as the supporting rope 57 is wound around the side of the connecting rod 55, the plug block 54 separates from the movable block 4, and the elastic member 53 returns to the state before the elastic deformation, forcing the first shovel block 41 and the second shovel block 42 to rotate on the side of the movable rod 2, so that the slot of the first receiving groove 411 and the slot of the second receiving groove 421 are opposite to each other, thereby improving the problem that the impurities fall out of the closed chamber after the movable rod 2 is pulled out of the drain pipe body 1, and improving the stability of the impurities in the closed chamber.

[0056] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
