Description

Technical Field

[0001] This invention relates to the field of building drainage, and more particularly to a building drainage structure that reduces clogging. Background Technology

[0002] Building drainage structures come in various forms, such as roof drainage structures.

[0003] In related technologies, building drainage structures include drainage pipes, one end of which extends to the sewer and the other end to the roof, thus allowing rainwater from the roof to drain into the sewer. However, during the design process, drainage pipes often have multiple bends to avoid obstructing traffic or to connect to the sewer. As leaves from the roof are transported along the drainage pipes, they tend to accumulate at these bends, resulting in poor drainage and preventing the timely removal of rainwater from the roof. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a building drainage structure that reduces clogging, thereby minimizing blockage of pipe components.

[0005] A building drainage structure for reducing clogging according to a first aspect embodiment of the present invention includes:

[0006] Piping assembly, which defines a drainage channel for conveying rainwater;

[0007] Mounting bracket, connected to the pipe assembly;

[0008] The transmission component includes a first pipe section and a transmission section. The first pipe section is rotatably connected to the mounting base and is disposed in the drainage channel. The first pipe section defines a first conveying channel that is opposite to the drainage channel. The transmission section is disposed on the inner wall of the first pipe section and extends along the axial and circumferential directions of the first pipe section so that rainwater drives the first pipe section to rotate through the transmission section when passing through the first conveying channel.

[0009] The shredder includes a second tube and a shredding section, the second tube being connected to the first tube and capable of rotating synchronously with the first tube, the second tube defining a second conveying channel opposite to the drainage channel, and the shredding section being disposed on the inner wall of the second tube to shred leaves passing through the second conveying channel.

[0010] According to the building drainage structure for reducing blockage, when the pipe assembly is in use, rainwater acts on the side surface of the transmission part when passing through the inner side of the first conveying channel. Since the transmission part is arranged in the axial direction and the circumferential direction of the first pipe part, the force of the rainwater is mostly converted into the circumferential force of the transmission part, and the transmission part moves in the circumferential direction around the central axis of the pipe assembly under the action of the rainwater. Since the second pipe part is connected with the first pipe part, the transmission part drives the cutting part to move in the circumferential direction, so that the cutting part rotates when the pipe assembly rotates. When the leaves pass through the second conveying channel along with the rainwater, the rotating cutting part cuts the leaves in the second conveying channel, and the cut leaves are less likely to be blocked in the pipe assembly when passing through the bending position of the pipe assembly, so that the pipe assembly can drain water smoothly, and the rainwater on the roof can be drained in time.

[0017] According to some embodiments of the present application, the transmission part is arranged in a spiral shape; and the conveying direction of the transmission part when rotating is arranged as the conveying direction of the pipe assembly to the rainwater.

[0035] According to the application, a clogging-reducing building drainage structure is disclosed, referring to Figure 1 With Figure 2 , comprising a pipeline assembly 100, a mounting seat 200, a transmission member 300 and a shredding member 400, the pipeline assembly 100 defines a drainage channel for conveying rainwater; the mounting seat 200 is connected to the pipeline assembly 100; the transmission member 300 comprises a first pipe portion 310 and a transmission portion 320, the first pipe portion 310 is rotatably connected to the mounting seat 200 and is arranged in the drainage channel, the first pipe portion 310 defines a first conveying channel which is in communication with the drainage channel, the transmission portion 320 is arranged on the inner wall of the first pipe portion 310 and extends in the axial direction and the circumferential direction of the first pipe portion 310, so that the rainwater drives the first pipe portion 310 to rotate through the transmission portion 320 when passing through the first conveying channel; the shredding member 400 comprises a second pipe portion 410 and a shredding portion 420, the second pipe portion 410 is connected to the first pipe portion 310 to be able to rotate synchronously with the first pipe portion 310, the second pipe portion 410 defines a second conveying channel which is in communication with the drainage channel, the shredding portion 420 is arranged on the inner wall of the second pipe portion 410 to shred the leaves passing through the second conveying channel.

[0036] Specifically, when the pipeline assembly 100 discharges the rainwater on the roof, the rainwater acts on the side surface of the transmission portion 320 when passing through the first conveying channel of the first pipe portion 310. Since the transmission portion 320 extends in the axial direction and the circumferential direction of the first pipe portion 310, most of the force of the rainwater is converted into the circumferential force of the transmission portion 320, so that the transmission member 300 moves circumferentially around the central axis of the pipeline assembly 100 under the action of the rainwater. Since the second pipe portion 410 is connected to the first pipe portion 310, the transmission member 300 drives the shredding member 400 to move synchronously circumferentially, so that the shredding portion 420 of the shredding member 400 moves rotationally in the first conveying channel. When the leaves pass through the second conveying channel of the second pipe portion 410 along with the rainwater, the rotating shredding portion 420 shreds the leaves in the second conveying channel, and the shredded leaves are less likely to be blocked in the pipeline assembly 100 when passing through the bending position of the pipeline assembly 100, so as to ensure that the pipeline assembly 100 can drain water smoothly, and the rainwater on the roof can be discharged in time.

[0037] It can be understood that, by the arrangement of the first pipe part 310 and the transmission part 300 arranged on the inner wall of the first pipe part 310, the first pipe part 310 causes the rainwater to flow to the transmission part 320, and the flow force of the rainwater is converted into the circumferential force of the transmission part 300 with a high probability, so that the rainwater can drive the transmission part 300 to rotate. At the same time, the transmission part 300 in this structure is not easy to cause the blockage of the pipe assembly 100, and the rainwater can flow through the pipe assembly 100 smoothly, so that the rainwater on the roof can be discharged in time.

[0038] The transmission part 300 adopts the above structure, by the arrangement of the second pipe part 410 and the shredding part 400 arranged on the inner wall of the second pipe part 410, the second pipe part 410 causes the leaves in the rainwater to pass through the second conveying passage, and the shredding part 400 can fully shred the leaves to prevent the leaves from being blocked in the bending position of the pipe assembly 100. At the same time, the shredding part 400 in this structure is not easy to cause the blockage of the pipe assembly 100, and the rainwater can flow through the pipe assembly 100 smoothly, so that the rainwater on the roof can be discharged in time.

[0039] It should be noted that the transmission part 320 and the shredding part 420 are designed for different purposes. The transmission part 320 mainly converts the flow force of the rainwater into the circumferential force, and the deformation degree of the transmission part 320 along the axial direction of the first pipe part 310 is about 45 degrees, so that the rainwater can drive the transmission part 300 to rotate without being blocked. Conversely, the shredding part 420 is used to shred the leaves in the rainwater, and the deformation degree of the transmission part 320 along the axial direction of the second pipe part 410 is about 15 degrees, so that the leaves can be fully shredded.

[0040] In some embodiments, the shredding part 400 is arranged after the transmission part 300, so that the rainwater first passes through the first conveying passage of the first pipe part 310 and then passes through the second conveying passage of the second pipe part 410. It can be understood that, by the above structure of the transmission part 300 and the shredding part 400, the force of the rainwater can be maximally converted into the transmission force of the transmission part 300, so as to drive the transmission part 300 to rotate and further drive the shredding part 400 to rotate.

[0041] Instead of the above scheme, the shredding part 400 is arranged before the transmission part 300, so that the rainwater first passes through the second conveying passage of the second pipe part 410 and then passes through the first conveying passage of the first pipe part 310. It can be understood that, by the above structure of the transmission part 300 and the shredding part 400, the shredding part 400 shreds the leaves in the rainwater, and the shredded leaves pass through the first conveying passage of the first pipe part 310, so as to avoid the blockage of the leaves in the first conveying passage.

[0042] In some embodiments, the second pipe portion 410 is slidingly sleeved outside the first pipe portion 310, and the first pipe portion 310 is fixed in the circumferential direction with the second pipe portion 410. The building drainage structure further comprises an elastic member 800, and the elastic direction of the elastic member 800 is set as the opposite direction of the set direction, and the set direction is the conveying direction of the rainwater by the pipe assembly 100. In some embodiments, the sliding range of the second pipe portion 410 is between 0.5 cm and 1.5 cm.

[0043] Specifically, when the chopping member 400 rotates around the central axis of the pipe assembly 100, the chopping member 400 reciprocates along the length direction of the pipe assembly 100 under the action of the rainwater and the elastic member 800. In this way, when the chopping member 400 chops the leaves, the leaves on the chopping member 400 can be shaken off, preventing the leaves from being blocked in the second conveying passage.

[0044] In some embodiments, the outer wall of the first pipe portion 310 has a first positioning surface 311, and the inner wall of the second pipe portion 410 has a second positioning surface 411. The first positioning surface 311 and the second positioning surface 411 are arranged in abutment. In this way, the first pipe portion 310 and the second pipe portion 410 are fixed in the circumferential direction. When the first pipe portion 310 rotates, the first pipe portion 310 acts on the second positioning surface 411 through the first positioning surface 311, thereby driving the second pipe portion 410 to rotate. In addition, the first pipe portion 310 and the second pipe portion 410 are convenient to install and disassemble.

[0045] Further, the inner wall of the pipe assembly 100 has a first annular protrusion 130, the outer wall of the second pipe portion 410 has a second annular protrusion 412, and the elastic member 800 is sleeved outside the second pipe portion 410 and abuts between the first annular protrusion 130 and the second annular protrusion 412. The elastic member 800 is hidden between the second pipe portion 410 and the pipe assembly 100, and between the first annular protrusion 130 and the second annular protrusion 412. In this way, the leaves and the like are prevented from moving to the position of the elastic member 800, and the elastic member 800 can be normally elastically deformed. In addition, the pipe assembly 100, the second pipe portion 410, and the elastic member 800 are convenient to install and disassemble when the building drainage structure is assembled.

[0046] In some embodiments, the transmission portion 320 is arranged in a spiral shape. The conveying direction of the transmission portion 320 when rotating is set as the conveying direction of the rainwater by the pipe assembly 100. It can be understood that the transmission portion 320 is arranged in a spiral shape. In this way, when the rainwater acts on the transmission portion 320, the force of the rainwater is mostly converted into the circumferential force of the transmission member 300, thereby driving the transmission member 300 to move in the circumferential direction. At the same time, the transmission portion 320 can convey the leaves in the rainwater when rotating, preventing the leaves from being blocked in the first conveying passage.

[0047] Further, the transmission part 320 comprises a plurality of slice parts 321, which are arranged in sequence and at intervals; and a displacement channel is defined between two adjacent slice parts 321. The transmission part 320 adopts the above structure, which further prevents the leaves from being blocked in the first conveying channel.

[0048] Further, the widths of the slice parts 321 are different, and the distance between the cutting edges of the slice parts 321 and the inner wall of the second pipe part 410 gradually increases along the conveying direction of the rainwater by the pipe assembly 100. In this way, the cutting part 420 of the cutting member 400 gradually cuts the leaves in the rainwater, and the leaves can be fully cut and are not easily blocked in the inner side of the second pipe part 410.

[0049] In some embodiments, the cutting part 420 is arranged in the form of a blade, so that the cutting part 420 can fully cut the leaves when rotating, thereby preventing the leaves from being blocked at the bending part of the pipe assembly 100.

[0050] In some embodiments, instead of being arranged in the form of a blade, the cutting part 420 is arranged in the form of a spiral, and the conveying direction of the cutting part 420 when rotating is arranged as the conveying direction of the rainwater by the pipe assembly 100. It can be understood that the transmission part 320 is arranged in the form of a spiral, and when cutting the leaves, the cutting member 400 can convey the leaves in the rainwater when rotating, thereby preventing the leaves from being blocked in the second conveying channel.

[0051] Further, the distance between the cutting edges of the cutting part 420 and the inner wall of the second pipe part 410 gradually increases along the conveying direction of the rainwater by the pipe assembly 100. It can be understood that the distance between the cutting edges of the cutting part 420 and the inner wall of the second pipe part 410 gradually increases, in this way, the cutting part 420 of the cutting member 400 gradually cuts the leaves in the rainwater, and the leaves can be fully cut and are not easily blocked in the inner side of the second pipe part 410.

[0052] In some embodiments, the pipe assembly 100 comprises a straight pipe 110 having an outwardly turned first flange 111 at an end thereof, a bent pipe 120 having an outwardly turned second flange 121 at an end thereof, and a mounting base 200 in the form of a ring-shaped body and abutting between the first flange 111 and the second flange 121. The building drainage structure further comprises a fastening bolt 700 sequentially penetrating the first flange 111, the mounting base 200 and the second flange 121, so as to fix the first flange 111, the second flange 121 and the mounting base 200 together, wherein the first pipe portion 310 is rotatably connected to the mounting base 200 through the bearing 210. It can be understood that the shredding member 400 is arranged at the water inlet of the straight pipe 110, so as to further prevent leaves from being blocked at the inlet of the bent pipe 120; in addition, when the first flange 111 and the second flange 121 are disassembled, the inner wall of the straight pipe 110 can be conveniently cleaned, and the shredding member 400 and the transmission member 300 can be conveniently replaced.

[0053] Instead of connecting the first flange 111 and the second flange 121 through the fastening bolt 700, in some embodiments, the building drainage structure further comprises a first ring-shaped member 500 and a second ring-shaped member 600, the first ring-shaped member 500 is sleeved on the straight pipe 110 and abuts against the back surface of the first flange 111, and the second ring-shaped member 600 is sleeved on the bent pipe 120 and abuts against the back surface of the second flange 121; wherein the fastening bolt 700 is used to connect between the first ring-shaped member 500 and the second ring-shaped member 600, so that the first flange 111, the mounting base 200 and the second flange 121 are tightly abutted together, and the straight pipe 110 and the bent pipe 120 are tightly connected. Through the arrangement of the first flange 111 and the second flange 121, it is not necessary to open a connecting hole for the fastening bolt 700 to pass through on the first flange 111 and the second flange 121, so as to ensure the integrity of the straight pipe 110 and the bent pipe 120, and the service life of the straight pipe 110 and the bent pipe 120 is improved; and under the action of the first ring-shaped member 500 and the second ring-shaped member 600, the first flange 111 and the second flange 121 can be tightly abutted on both sides of the mounting base 200.

[0054] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
