Description

TECHNICAL FIELD

[0001] The present application relates to a building drainage device, in particular to a double stack same-floor drainage collector. BACKGROUND

[0002] In the field of same-floor drainage of residential buildings, all pipes between water fixtures and drainage stacks are placed in the indoor layer. In the original same-floor drainage bathroom, considering the size of the pipe, the height of the floor drain, and the placement of the water seal, the drainage branch pipe can only be placed below the floor tiles. Due to the diameter of the drainage branch pipe, the slope of the drainage branch pipe and the height of the water seal cannot be increased, so the structural plate of the bathroom is offset downward (also known as: lowered plate) to accommodate the drainage pipe and the water seal of the water fixture. Finally, the surface is poured with reinforced concrete after backfilling with ceramic particles. However, because the drainage branch pipe is higher than the structural plate, and the lowered plate area is relatively closed, there is a common problem of water accumulation in the lowered plate area. If water accumulates in the lowered plate area, a large amount of water will accumulate over time, eventually causing problems such as damage to the waterproof layer, peeling of the wall, water on the floor, and leakage of the structural plate. Because of the need for maintenance, the surface layer of reinforced concrete in the lowered plate area needs to be broken open. The backfilled ceramic particles are removed, the leakage points are repaired, the waterproofing is removed, and the construction is re-done, so the maintenance cost is extremely high. Because the lowered plate actually wastes the indoor height, and has high cost and difficult maintenance, the non-lowered plate same-floor drainage technology has emerged.

[0003] The current non-lowered plate same-floor drainage technology is to collect the pipes of water fixtures other than the toilet to a shared water seal device, and place the shared water seal in the structural plate, using the thickness of the structural plate to solve the height restriction of the water seal, thereby achieving non-lowered plate same-floor drainage. Because the flow passage under the water seal baffle is relatively narrow, when multiple water fixtures are draining, the narrow flow passage under the water seal baffle limits the drainage flow of the product and cannot meet the drainage requirements of some larger fixtures.

[0004] The current non-lowered plate same-floor drainage collector cannot correspond to a double stack system, and the drainage environment layout is complex and variable, requiring a large space to be reserved for the same-floor drainage collector. In addition, because the strength of the collector itself is relatively small compared to the strength of the structural plate, the strength of the structural plate around the drainage stack is ultimately reduced.

[0005] In addition, the current same-floor drainage collector has a risk of blockage and requires professional tools for unblocking after blockage. Manual unblocking is difficult because the space is too small to enter, resulting in difficulty in unblocking. Even some drainage collectors cannot be unblocked, resulting in the entire drainage stack being scrapped. SUMMARY

[0006] The application provides a double riser same-layer drainage collector, which is used for solving the problems of narrow water seal passage, small drainage flow, incapability of manual clearing and small water seal capacity of the existing drainage collector.

[0007] To achieve the above object, the technical scheme of the application is as follows:

[0018] Further, the periphery of the vent pipe section, the drainage pipe section and the shell and the connecting part are horizontally provided with a surrounding waterproof wing ring.

[0019] The end of the upper air pipe interface, the lower air pipe interface, the upper drainage pipe interface and the lower drainage pipe interface can be connected by a rubber ring, or connected and fixed with the corresponding pipe by a rubber ring and a flange.

[0020] Further, a water seal maintenance opening is arranged on the water seal cavity, and the water seal maintenance opening is located between the drainage pipe section and the air pipe section and is located on the other side of the water collection opening on the upper end of the water seal cavity.

[0021] The water seal maintenance opening is provided with a water seal maintenance cover.

[0022] Further, a water accumulation discharge unit is arranged on the same side of the water collection opening, and the water accumulation discharge unit is communicated with the water seal cavity.

[0023] Further, a four-way adapter matched with the water collection opening is arranged on the water collection opening, a collection four-way is arranged on the four-way adapter, and a four-way maintenance cover is arranged on the collection four-way; and the water collection opening is arranged in an inclined manner.

[0025] Further, a one-way drainage device is arranged in the water accumulation discharge unit, and the one-way drainage device is used for draining water into the water seal cavity.

[0026] Further, the projection of the lower end of the water seal baffle on the horizontal plane is a curve, the upper end of the water seal baffle is a first plane plate, and the lower end is a curved plate; or the upper end is a third plane plate, and the lower end is a wave-shaped plate.

[0027] Compared with the prior art, the beneficial effects of the present application are as follows:

[0028] 1. The lower end of the water seal baffle with a non-plane plate in the present application prolongs the length of the water seal baffle in a limited space, directly increases the flow passage area below the water seal baffle, and improves the drainage flow.

[0029] 2. Compared with the prior art, the present application adopts the integrated design of the air pipe section and the drainage pipe section, utilizes the narrow position between the two risers, and solves the problem that the existing same-floor drainage collector scheme is too large to be installed.

[0032] The other end of the water seal inspection cover with the iron hook can be used to clear debris from inside the water seal cavity; it can also be used to seal the water seal inspection port under normal circumstances.

[0033] 5. In this invention, the water drainage unit can drain the water in the floor tile pad layer that cannot enter the water collection port into the water seal cavity, preventing the water from damaging the waterproof layer of the structural board.

[0034] 6. Compared with existing non-lowering floor drainage products, this invention adopts a method of placing the water seal between the drainage pipe and the vent pipe, which greatly saves indoor space, improves the strength of the structural slab, and reduces the indoor area occupied by pipes during indoor decoration.

[0035] 7. Compared with existing non-lowering floor drainage products, this invention uses two inspection ports. When the collector becomes clogged and manual cleaning is required, it allows for manual unblocking from two directions, ensuring convenient maintenance. Simultaneously, the inclined design of the collection inlet ensures that a hand can directly touch the bottom of the water seal channel through the inlet, making it easier to clean. The inclined collection inlet also facilitates the installation of large-diameter floor drains, ensuring drainage speed.

[0036] 8. In this invention, the height of the water collection port can be increased by using a four-way adapter and a four-way junction to adapt to the actual situation of different thicknesses of the structural plate. Attached Figure Description

DETAILED DESCRIPTION

[0045] The application will be further explained in conjunction with the accompanying drawings and specific embodiments.

[0046] A dual riser same-floor drainage collector, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , includes a vent pipe section 1, a water seal section, and a drain pipe section 2 designed in one body. The vent pipe section 1 and the drain pipe section 2 are arranged side by side, and the water seal section is located in the middle of the side of the drain pipe section and the vent pipe section. The periphery of the vent pipe section 1, the drain pipe section 2, the housing 3, and the connecting part is provided with a waterproof wing ring 17 protruding outward in the horizontal direction, which is used to combine more tightly with the concrete of the building structure plate.

[0047] The vent pipe section 1 includes a vent pipe upper interface 11, a vent communication section 12, and a vent pipe lower interface 13 arranged from top to bottom; the vent communication section 12 is curved radially outward, that is, the axis of the vent communication section 12 is deviated outward relative to the axes of the vent pipe upper interface 11 and the vent pipe lower interface 13, so that the capacity of the water seal cavity 4 in the water seal section is increased, more water can be accommodated, the natural evaporation time of the water seal is prolonged, and thus the effective sealing time of the water seal is prolonged.

[0048] The drain pipe section 2 includes a drain pipe upper interface 21, a drain communication section 22, and a drain pipe lower interface 23 arranged coaxially from top to bottom.

[0049] The end portions of the vent pipe upper interface 11, the vent pipe lower interface 13, the drain pipe upper interface 21, and the drain pipe lower interface 23 can be connected and fixed with the corresponding pipes by a rubber ring, or by a rubber ring and a flange.

[0050] The water seal section includes a water seal cavity 4, a water seal baffle 5, a water seal drain 6, a water seal access 7, and a water collection port 8.

[0051] The vent pipe section 1, the drain pipe section 2 and the shell 3 surround to form a water seal cavity 4. The top of the water seal baffle 5 is installed on the top of the water seal cavity 4, and the bottom is suspended in the water seal cavity 4, so that the water seal cavity 4 becomes a U-shaped structure cavity, and the bottom end of the water seal cavity 4 is a water flow passage. One side of the water seal baffle 5 is fixed on the outer side wall of the vent communication section 12 and the vent pipe lower interface 13, and the other side is fixed on the outer side wall of the drain communication section 22 and the drain pipe lower interface 23. The water seal baffle 5 is a special-shaped curved surface plate, the horizontal projection of the upper end surface and the lower end surface of the water seal baffle 5 has an included angle, the upper end of the water seal baffle 5 is a first flat plate, and the lower end is a curved surface plate; or the water seal baffle is an upper end third flat plate, a lower end wave-shaped plate and other plates capable of accelerating water flow. The composition of the curved surface plate is that the middle is a second flat plate, and each side of the second flat plate is a single wave-shaped plate with opposite directions. The water seal baffle 5 can accelerate the flow rate of water in the water seal cavity 4, so that the sewage in the water seal cavity 4 is more smoothly discharged. The upper end and the lower end of the water seal baffle 5 can also be flat plates, and the middle part is a curved surface plate.

[0052] The top end of the water seal cavity 4 is provided with a water collecting port 8 communicating the water seal cavity 4 and the drain pipe of the water using device, for collecting domestic sewage flowing out from the water using device through the drain branch pipe. The water collecting port 8 is located on the same side of the water seal baffle 5, is higher than the lower end surface of the water seal drain port 6, and is lower than or flush with the upper end surface of the drain pipe upper interface 21. The water collecting port 8 is inclinedly arranged,

[0053] The side wall of the drain communication section 22 is provided with a water seal drain port 6, so that the drain communication section 22 communicates with the water seal cavity 4, and then the sewage entering the water seal cavity 4 from the water collecting port 8 is discharged through the lower drain pipe in the drain communication section 22 and the drain pipe lower interface 23.

[0054] The other side of the drain pipe section 2 and the vent pipe section 1 is provided with a water seal maintenance port 7 located on the shell 3 and communicating with the water seal cavity 4, for maintenance, checking and clearing the hair and other sundries affecting the water seal cavity 4 in an extreme case. The water seal maintenance port 7 is provided with a water seal maintenance cover 16, which also facilitates manual cleaning of the bottom of the water seal flow passage on the water collecting port side.

[0055] One side of the water collecting port 8 is provided with a water accumulation discharge unit 9, which unidirectionally communicates with the water seal cavity 4, so that the accumulated water in the floor cushion layer flows into the water seal cavity; a one-way valve in the water accumulation discharge unit 9 can prevent the sewage in the water seal cavity 4 from flowing out of the water accumulation discharge unit 9 in the opposite direction.

[0056] As Figure 4 and Figure 6As shown, the water collecting port 8 can also be provided with a matching four-way adapter 14, and the four-way adapter 14 is installed with a collecting four-way 10, so that the overall height of the device is adjustable, and is suitable for building structure plates of various thicknesses. The collecting four-way 10 is installed with a four-way maintenance cover 15, which is used for manual dredging when the blockage is difficult to dredge. The collecting four-way 10 can also be directly installed on the water collecting port 8 to directly adjust the height.

[0057] The use process of the collector in the present application is as follows: the air pipe upper interface 11, the air pipe lower interface 13, the drain pipe upper interface 21 and the drain pipe lower interface 23 are all installed with corresponding pipes.

[0058] Since there may be hair and other sundries in the sewage during the drainage process, causing the inside of the water seal cavity 4 to be blocked, the water seal maintenance cover 6 can be removed, and the water seal maintenance opening 7 can be used for manual cleaning or using the hook or other tools provided on the water seal maintenance cover 6 for cleaning. The four-way maintenance cover on the collecting four-way can also be removed for manual dredging.

[0059] If the height of the collector does not meet the use scene, the height of the water collecting port 8 can be increased by installing the four-way adapter 14 and the collecting four-way 10 on the water collecting port 8, so that the collector meets the use scene.
