DETAILED DESCRIPTION

[0043] The present invention will be described in detail and specifically below through specific examples to provide a better understanding of the present invention, but the following examples do not limit the scope of the present invention.

[0044] like Figure 1 、 Figure 12 and Figure 13As shown, in some embodiments, a six-way drainage manifold with an automatic gear-triggered closing valve is provided, which mainly includes a sewage and waste diversion pipe well 100 and a six-way drainer 200. The six-way drainer 200 is arranged in the sewage and waste diversion pipe well 100 and is staggered with each riser in the sewage and waste diversion pipe well 100 to make full use of the space in the sewage and waste diversion pipe well 100 and arrange it reasonably.

[0045] The six-way drain 200 can be directly connected to the four directions of the wastewater diversion manifold 100, allowing the sewage riser to connect to the sewage equipment in four directions without obstruction. Here, the direct connection and unobstructed connection refer to a point-to-point linear connection, such as using a straight pipe to connect to a toilet sewage pipe or other drainage equipment, rather than using a curved pipe to connect.

[0046] Specifically, if Figure 2 、 Figure 3 and Figure 4 As shown, the six-way drainer 200 primarily comprises a housing 201 with six ports located on the top, bottom, and perimeter of the housing. The housing 201 is a four-sided columnar structure with two vertical ports 202 located at the top and bottom, respectively. These two vertical ports 202 are arranged in a corresponding arrangement, connecting to the upper and lower sewage riser pipes 101, respectively. Horizontal ports 203 are located in the middle of the four walls of the housing 201. These ports 203 are hollow, tubular, and extend outward, corresponding to the four directions of the manhole.

[0047] like Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, to achieve the opening and closing of the four transverse interfaces 203 on the housing 201, when sewage equipment is connected in at least one direction, the corresponding transverse interface 203 is opened to achieve communication between the sewage equipment and the sewage standpipe 101. And / or when sewage equipment is not connected in at least one direction, the transverse interface 203 in that direction is closed to prevent sewage from the sewage standpipe 101 from leaking through the transverse interface 203. The sealing cover plate 205 and sealing ring 206 at the port are used to achieve double closure to ensure the sealing of the transverse interface 203. This embodiment creatively provides a semi-automatic opening and closing valve mechanism at each transverse interface 203, which is a gravity valve.

[0048] Specifically, sealed and vertically connected gear storage bins 207 and baffle storage bins 208 are respectively provided at the connection between the top of the four horizontal interfaces 203 on the shell 201 and its side walls. The gear storage bin 207 is composed of a gear storage bin, the bottom and inner side walls of which are fixed at the connection between the horizontal interface 203 and the shell 201, and the bottom and inner side walls are solidly open, which are respectively connected with the inner cavity of the horizontal interface 203 and the baffle storage bin 208 on the outer periphery of the shell 201 for installing a water retaining plate 209 and a fan-shaped gear plate 210.

[0049] like Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the water baffle 209 is movably mounted within the baffle storage bin 208 and can be raised and lowered within the baffle storage bin 208. By driving the water baffle 209 upward, the transverse interface 203 is opened, establishing interconnection between its front and rear ends. Alternatively, by controlling the water baffle 209 downward, its lower end seals the inner wall of the transverse interface 203, thereby sealing the inner port of the transverse interface 203 and acting as a valve to control the opening and closing of the transverse interface 203.

[0050] like Figure 9 and Figure 10 As shown, to achieve the lifting and lowering control of the water retaining plate 209, a sector gear plate 210 is movably arranged in the gear storage bin 207 on its front side. The sector gear plate 210 is a sector plate structure with a pin 2101 provided at its apex and a first rack 2102 provided on its outer peripheral wall. The sector gear plate 210 is movably hinged to the body of the gear storage bin 207 via the pin 2101, so that the sector gear plate 210 can be flipped up and down with the apex as the center point. The flipping range is limited to the flipping space formed by the horizontal interface 203 below and the gear storage bin 207 above.

[0051] At the same time, racks are provided on the outer periphery of the sector gear plate 210, meshing with the racks on the outer wall of the water baffle 209. During operation, the sector gear plate 210 is controlled to flip up and down within the flipping space. Due to the meshing connection between its outer periphery and the water baffle 209, the flipping of the sector gear plate 210 inevitably drives the water baffle 209 up and down. This controls the raising and lowering of the water baffle 209, and consequently, the opening and closing of the transverse interface 203.

[0052] Specifically, if Figure 5 、 Figure 6 、 Figure 7 and Figure 12As shown, when the six-way drainer 200 is in use, its working principle is as follows: when it is necessary to connect the horizontal interface 203 in one direction of the six-way drainer 200 to the sewage discharge equipment in that direction, a drainage transverse pipe 204 is used to establish the connection; when one end of the drainage transverse pipe 204 is inserted into the horizontal interface 203 in that direction, its end abuts against the side wall of the fan-shaped gear plate 210 inwardly, and when the drainage transverse pipe 204 continues to be inserted inward, the drainage transverse pipe 204 lifts the fan-shaped gear plate 210 and flips it upward with its vertex as the center of the circle, and in the process of the fan-shaped gear plate 210 flipping upward, it simultaneously drives the water retaining plate 209 to rise, thereby opening the horizontal interface 203 to connect to the sewage riser.

[0053] In addition, at other horizontal interfaces 203 that are not connected to the sewage equipment, since the drainage horizontal pipe 204 is not inserted, the fan gear plate 210 is not driven by external force, and the fan gear plate 210 and the water retaining plate 209 engaged with it descend under the action of their own gravity. The water retaining plate 209 descends to the bottom of the horizontal interface 203 and is sealed with the inner wall of the horizontal interface 203, thereby achieving the purpose of closing the horizontal interface 203.

[0054] In some of these embodiments, Figure 1 and Figure 10 As shown, the risers in the sewage and waste diversion manhole 100 include at least a sewage riser 101, a wastewater riser 102, and a ventilation riser 103, and the sewage riser 101, the wastewater riser 102, and the ventilation riser 103 are arranged in a herringbone shape, with a compact layout. Under the premise of meeting the installation spacing of various construction requirements, the area of ​​the manhole in the traditional I-type layout is only increased by 0.032㎡. The area of ​​the I-type layout manhole is 0.414㎡, the area of ​​the L-type layout manhole is 0.449㎡, and the area of ​​the herringbone layout manhole is 0.446㎡. Figure 1 The adoption of this four-way integrated drainer solution not only achieves four-way sewage and waste diversion drainage, but also increases water supply pipes and meets the technical conditions for same-floor drainage without lowering the slab, greatly improving the efficiency and flexibility of space utilization and bringing more possibilities to SI system buildings.

[0055] As a supplement, the sewage and waste diversion pipe shaft 100 is arranged in the center of the room (household space), and the water supply and drainage equipment can be flexibly arranged in the surrounding space, for example, it can be arranged close to the secondary beam of the structure. By arranging the sewage and waste diversion pipe shaft 100 in the center of the room close to the secondary beam, the sewage and waste diversion pipe shaft 100 can be connected to the bathroom in all four directions, which is suitable for new construction and reconstruction with decentralized water supply and drainage function requirements. The centering refers to setting the sewage and waste diversion pipe shaft 100 in the center of a room in a household or house, rather than just referring to a bathroom or a separate room unit. By arranging the sewage and waste diversion pipe shaft 100 in the center of the room, it can radiate to the four directions of the room to connect the water supply and drainage equipment in multiple bathrooms and / or kitchens.

[0056] The sewage and waste diversion manhole 100 includes a manhole wall, a sill, an installation port, and an inspection port. The sill is located at the bottom of the manhole wall. The internal space of the manhole wall is 530 mm long and 420 mm wide, and is equipped with a sewage riser 101 with a diameter of 110 mm, a wastewater riser 102 with a diameter of 110 mm, and a ventilation pipe 103 with a diameter of 110 mm. The floor is provided with corresponding riser sleeves. If the wastewater riser 102 is used in a multi-story building, a diameter of 75 mm can be used. The size of the manhole can be reduced accordingly, and a water supply pipe can be arranged in the gap on one side of the ventilation pipe.

[0057] In some of these embodiments, Figure 1 and Figure 6 As shown, the sewage riser 101 is located at the top of the herringbone shape, while the wastewater riser 102 and ventilation riser 103 are located at the lower sides, forming a staggered arrangement. Furthermore, one of the transverse ports 203 on the housing 201 is located between the wastewater riser 102 and the ventilation riser 103.

[0058] In order to achieve the purpose of unobstructed connection of the sewage riser 101 in four directions, the six-way drainer 200 installed on it is arranged to be opposite, that is, one of the horizontal interfaces 203 on the six-way drainer 200 is arranged between the wastewater riser 102 and the ventilation riser 103, so that the four horizontal interfaces 203 of the six-way drainer 200 are staggered with the wastewater riser 102 and the ventilation riser 103 on both sides.

[0059] Specifically, if Figure 2 As shown, the sewage riser 101, wastewater riser 102 and ventilation riser 103 are centrally arranged in the sewage and waste diversion pipe well 100 in a triangular shape, and each riser has the same distance from the inner wall of the sewage and waste diversion pipe well 100, so as to facilitate the installation of an annular wastewater drainage pipe 400 between the sewage riser 101, wastewater riser 102 and ventilation riser 103 and the inner wall of the peripheral sewage and waste diversion pipe well 100.

[0060] In some of these embodiments, Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 12 As shown, the six-way drainer 200 further includes a drainage riser 212 for connecting the wastewater riser 102 up and down and a drainage horizontal pipe 204 for horizontal sewage discharge equipment.

[0061] Specifically, there are two vertical drainage pipes 212, one end of which is detachably inserted into the upper and lower vertical interfaces 202 of the housing 201 and sealed with a sealing ring, used to connect the sewage riser 101 and the sewage equipment. There is at least one horizontal drainage pipe 204, which is specifically determined by the number of sewage equipment and is detachably inserted into the four horizontal interfaces 203 around the housing 201. On the one hand, it is used to drive the sector gear plate 210 and the water retaining plate 209 to rise to open the horizontal interfaces 203, and on the other hand, it directly connects the corresponding sewage equipment with the intermediate sewage riser 101.

[0062] In some of these embodiments, Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 8 As shown, the six-way drainer 200 further includes a sealing cover plate 205 and a sealing ring 206 , and the sealing cover plate 205 and the sealing ring 206 are made of metal or plastic.

[0063] Specifically, the sealing cover plate 205 is sealed at the inlet end of the drainage transverse pipe 204 through a corresponding sealing ring 206 . The sealing cover plate 205 is used to close the transverse interface 203 where the drainage transverse pipe 204 is not installed.

[0064] The drainage transverse pipe 204 is threadedly connected to the corresponding transverse interface 203 through a corresponding sealing ring 206. The sealing ring 206 is used to lock and fix the sealing cover plate 205 and the corresponding drainage transverse pipe 204 at the end of the transverse interface 203.

[0065] In some of these embodiments, Figure 2 、 Figure 3 、 Figure 4 and Figure 11 As shown, the water retaining plate 209 is an upper, lower circular structure. Specifically, a second rack 2091 is vertically disposed in the middle of its outer wall, and a semicircular plate 2092 is disposed at the bottom. The second rack 2091 meshes with the first rack 2102 on the outer wall of the sector gear plate 210. Below it, a sealing groove 211 is formed on the inner wall of the corresponding transverse interface 203, and the semicircular plate 2092 at the bottom is correspondingly embedded in the sealing groove 211, thereby sealing the transverse interface 203.

[0066] In some embodiments, the housing 201 and its surrounding gear storage bin 207 and baffle storage bin 208 are integrally formed and made of metal or engineering plastic, such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), or ABS plastic. To facilitate installation of the water baffle 209, a slot communicating with the baffle storage bin 208 may be provided on the top of the housing 201 as needed, and a cover plate 213 may be used to seal and secure the slot.

[0067] In some of these embodiments, Figure 2 and Figure 13 As shown, in order to achieve the purpose of non-dropping same-layer drainage and free layout of the toilet location around the sewage and waste diversion pipe shaft 100, the six-way drainage integrator also includes a non-dropping same-layer drainage embedded part 300 arranged at the bottom of the sewage and waste diversion pipe shaft 100, and the upper and lower riser interfaces of the non-dropping same-layer drainage embedded part 300 are correspondingly connected to the wastewater riser 102, and its side interface is correspondingly connected to the annular wastewater drainage pipe 400 outward.

[0068] It is worth noting that the non-drop floor same-level drainage embedded parts 300 and the water supply riser 104 in the sewage and waste diversion pipe well 100 are respectively located in the left and right side spaces of the ventilation riser 103.

[0069] For ease of installation, the embedded components 400 for non-dropping, same-level drainage are required to be compact and space-saving. As a preferred embodiment, these embedded components utilize independently developed, self-contained, water-sealed siphon-type wastewater drainage riser embedded components, comprising an integrated wastewater riser connector and a three-way water-sealing pipe.

[0070] The six-way six-way drainer 200 is combined with the non-dropping same-floor drainage embedded parts 400 and the integrated bathroom products available on the market. Through the non-dropping same-floor drainage technology, the bathroom can be flexibly arranged around the sewage and waste diversion pipe well 100. The position, shape and size of the bathroom are not affected by the layout of the upper and lower rooms.

[0071] Furthermore, in some of the embodiments, Figure 1 and Figure 13 As shown, the six-way drainage manifold also includes an annular wastewater drainage pipe 400 disposed at the bottom of the wastewater diversion pipe well 100 and connected to the sewage riser 101. The annular wastewater drainage pipe 400 is located at the bottom of the wastewater diversion pipe well 100 and is arranged around the sewage riser 101, the wastewater riser 102, and the ventilation riser 103. The pipe is equipped with corresponding four-way connectors and five-way connectors.

[0072] Specifically, the annular wastewater drainage pipe 400 is arranged in a circular shape around the sewage riser 101, wastewater riser 102, and ventilation riser 103. It is connected to the drainage equipment that discharges the wastewater through a number of four-way connectors distributed around the annular pipe. The three-dimensional four-way connectors are distributed around the annular wastewater drainage pipe 400, corresponding to the installation ports around the pipe well. The upward vertical interface has a sealing cap to reserve a third drainage device such as a washing machine, and the horizontal interface is connected to a check valve.

[0073] The annular wastewater drainage pipe 400 is connected to the non-dropping slab same-level drainage embedded part 300 through a five-way connector installed thereon. One inner interface of the five-way connector is used to connect to the non-dropping slab same-level drainage embedded part 300, and the vertical interface on it and the other horizontal interface on the outside are used to connect to the drainage equipment.

[0074] In summary, the six-way drainage manifold provided by this invention can be used in a SI system with a four-way integrated drain as its core, enabling the flexible layout of restrooms around manholes. Redundant connections can be closed with sealing covers, providing flexibility and convenience. Its cleverly designed opening and closing mechanism saves space, offers flexible functionality, and facilitates installation, reducing errors in traditional civil engineering work. It can be used to drain sewage and wastewater with a diameter of 110 mm to 50 mm, making it a valuable addition to the SI building system and possessing significant practical value.

For those skilled in the art, any equivalent modifications and substitutions to the present invention are also within the scope of the present invention. Therefore, any equivalent changes and modifications made without departing from the spirit and scope of the present invention are intended to be encompassed within the scope of the present invention.
