Example 1

Referring to fig. 1 to 9, the present embodiment provides a drainage assembly for a balcony, which is inscribed between main drainage pipes and is in up-and-down communication with the main drainage pipes when actually installed. The device comprises a horizontal pipe drainage component 2 communicated with a main drainage pipeline and a water seal component 3 communicated with the horizontal pipe drainage component 2. In the present embodiment, the waste water refers to water discharged from a balcony, a washing machine, or the like.

Referring to fig. 2 to 7, the horizontal pipe drainage assembly 2 in this embodiment is a flat hollow cavity inside, and is used for collecting the wastewater drained by the water seal assembly 3 into the main drainage pipeline, one end of the horizontal pipe drainage assembly 2 is communicated with the main drainage pipeline, and the other end is communicated with the water seal assembly 3; the bottom surface of the cavity of the horizontal pipe drainage component 2 is obliquely arranged, and one end connected with the water seal component 3 is higher than the other end of the horizontal pipe drainage component 2. The inclined arrangement of the bottom surface of the horizontal pipe drainage assembly 2 is used for reducing the waste water temporarily remained in the horizontal pipe drainage assembly 2, so that the waste water introduced by the water seal assembly 3 flows under the action of self gravity and can be smoothly collected into a main drainage pipeline. Moreover, when the discharge amount of wastewater in the main drainage pipeline is large and the water pressure is greater than the water pressure of wastewater drained by the water seal assembly 3, the wastewater can also flow back to the main drainage pipeline to be discharged due to the influence of gravity, so that the wastewater is prevented from being reversely discharged to the water seal assembly 3.

Further, the horizontal pipe drainage assembly 2 comprises a first fitting part 21 and a second fitting part 22, and the first fitting part 21 and the second fitting part 22 are closed to form a cavity of the horizontal pipe drainage assembly 2 for circulating waste water; the bottom surface of the cavity of the horizontal pipe drainage assembly 2 is inclined, in particular to the bottom surface of the second assembly part 22.

In the embodiment, the first assembly member 21 and the second assembly member 22 are made of plastic, so as to reduce the weight of the first assembly member 21 and the second assembly member 22, and prevent the first assembly member 21 and the second assembly member 22 from rusting and damaging the service life thereof; and the first assembly part 21 and the second assembly part 22 made of plastics have low production and processing cost and are convenient to assemble. Indeed, in other preferred embodiments, the first assembly member 21 and the second assembly member 22 may also be made of cast iron or ceramic.

Further, the first assembly part 21 and the second assembly part 22 both adopt an integrated structure, so that the possibility of leakage of waste water from the horizontal pipe drainage component 2 is reduced, and the sealing performance of the horizontal pipe drainage component 2 is improved.

Further, the first fitting 21 comprises a first riser interface 211 and a waste pipe interface 212; the second fitting 22 includes a second riser interface 221 and a trap interface 222; the upper main drainage pipeline is communicated with the horizontal pipe drainage assembly 2 through a first vertical pipe connector 211, and the lower main drainage pipeline is communicated with the horizontal pipe drainage assembly 2 through a second vertical pipe connector 221.

Further, the second fitting 22 further comprises a second riser 27 in communication with the second riser interface 221.

Further, the second assembly member 22 and the second vertical pipe 27 are of an integrated structure, so that the influence of resistance on the fluidity of the waste water at the joint due to a non-integrated structure is reduced, the waste water can be discharged in a swirling manner along the wall of the pipe, and the possibility of leakage is reduced.

Further, the bottom surface of the second fitting 22 in this embodiment is obliquely disposed at an angle such that water entering the horizontal pipe drain assembly 2 can enter the second riser pipe 27 in a tangential direction of the second riser pipe 27, thereby reducing the possibility of water plug formation in the second riser pipe 27.

Further, in the drainage assembly for the building balcony, waste water may be deposited on the floor surface during the use process, in order to drain the waste water deposited on the floor surface into the second vertical pipe 27, the horizontal pipe drainage assembly 2 further comprises an anti-overflow mechanism which is arranged in the cavity and is positioned at the second vertical pipe connector 221, and the anti-overflow mechanism comprises an anti-overflow ball seat 23 and an anti-overflow ball 24; the overflow-preventing ball seat 23 is provided with a water accumulation discharge hole 231 communicated with the second riser 27, and the overflow-preventing ball 24 is placed on the water accumulation discharge hole 231; a accumulated water inflow hole 232 is further formed in the first assembly member 21 at a position corresponding to the accumulated water discharge hole 231, and the diameter of the accumulated water inflow hole 232 is smaller than that of the anti-overflow ball 24.

Specifically, the anti-spill ball seat 23 is arranged on the inner wall of the second assembly member 22; the centers of the water inflow hole 232 and the water discharge hole 231 are located on the same axis.

Therefore, the accumulated water discharge hole 231 formed in the overflow preventing ball seat 23 horizontally limits the overflow preventing ball 24, and the overflow preventing ball 24 can move only in the vertical direction between the overflow preventing ball seat 23 and the accumulated water discharge hole 231 formed in the overflow preventing ball seat 23. When there is accumulated water on the floor surface, the accumulated water can enter through the accumulated water inflow hole 232 and flow out of the accumulated water discharge hole 231, and then is discharged into the second riser 27; meanwhile, when the overflow of the wastewater occurs, the overflow preventing ball 24 is tightly attached to the accumulated water inflow hole 232 by the buoyancy of the wastewater to seal the accumulated water inflow hole 232, so as to prevent the overflowing wastewater in the second riser 27 from overflowing the cyclone.

Further, the horizontal tube drain assembly 2 further comprises a drainage plate 26. The flow guide plate 26 is arranged at the second vertical pipe interface 221 and is used for guiding the wastewater flowing into the horizontal pipe drainage assembly 2 from the water seal assembly 3 to enter the second vertical pipe 27 along the tangent line of the second vertical pipe 27 so as to realize wall-attached rotational flow of the wastewater; or when the flow of the wastewater in the horizontal pipe drainage assembly 2 is large, in order to ensure that the wastewater can enter the second vertical pipe 27 along the tangential direction of the second vertical pipe 27, the wastewater entering the horizontal pipe drainage assembly 2 enters the second vertical pipe 27 along the tangential direction of the second vertical pipe 27 under the guidance of the drainage plate 26, and when the flow of the wastewater in the horizontal pipe drainage assembly 2 is large, the wastewater can still be discharged in a wall-attached swirling manner from the second vertical pipe 27.
