Description

Improved zero-falling plate same-floor drainage collector for building

Technical Field

The utility model relates to a zero board that falls of building is with layer drainage device especially is used for including in the construction including living in, official working etc. multiple building sewage/waste water discharge pipeline zero fall board with layer drainage manifold such as bathroom, balcony.

Background

In order to solve the problem of the whole or local board lowering mode adopted in the toilet same-layer drainage system of the building for a long time, the publication number is CN 104975645A; chinese patent documents CN104727430A and the like propose some zero-drop plate same-layer drainage joints/devices for buildings, but there are still many problems or defects. In order to solve these problems, chinese patent publication No. CN110725369A reports a new structure form of building zero-drop plate same-floor drainage device, whose basic structure is that a vertical pipe offset cavity section is provided between a vertical pipe inlet joint and a vertical pipe outlet joint provided at both ends of a central line of a pipeline, the central line of a water flow passing through a water flow channel deviates from the central line of the pipeline, and a sewage horizontal branch pipe joint for connecting a sewage discharge pipeline of a toilet stool is provided in the vertical pipe offset cavity section; a shared water seal chamber which is independent and provided with a waste water transverse branch pipe joint for connecting drainage pipes including a wash basin, a bathtub, a floor drain and the like is arranged in parallel with the vertical pipe offset cavity section; the common water seal chamber is merged with a water outlet of the riser offset chamber section below the pipeline and is connected to a riser water outlet nozzle along a lower section of the pipeline having a water flow centerline coincident with the centerline of the pipeline. The same-floor drainage device with the structure has the advantages that water flow discharged from an upper-floor building, sewage discharged from a sewage discharge pipeline connected with a toilet stool and collected wastewater discharged from wastewater horizontal branch pipes including a wash basin, a bathtub, a floor drain and the like can be discharged separately, and then the collected wastewater is finally converged and then is discharged together through a vertical pipe water outlet connecting pipe. However, it has been found that there are some points to be improved, for example, after the water flow discharged from the superstructure vertically falls to the floor along the common vertical pipe, although a drift channel with a water flow center line deviated to one side of the central axis of the water inlet and the water outlet is arranged in the middle of the water flow channel, if the falling flow rate is not effectively reduced or the water flow is decompressed, the flow rate of the vertically falling water flow in the vertical pipe is increased to a limit value and a cross-section seal may be formed instantaneously in the common vertical pipe, so that the gas in the common vertical pipe generates a larger positive pressure or a negative pressure, and the larger positive pressure may affect the stability of the liquid level of the common water seal. For another example, the structure of the vertical pipe may be that the water flow from the water seal chamber to the water seal chamber is directed to the vertical pipe, and the vertical pipe is connected to the water seal chamber. In addition, the zero-drop board same-floor drainage gathering device and the common water seal thereof are usually installed in a pipe shaft, the opening for checking/maintaining and cleaning the common water seal is arranged at a position which is flush or approximately flush with the ground finishing surface layer in the pipe shaft, and the height of the access door arranged on the wall of the pipe shaft from the ground often exceeds the arm length of a normal person (for example, when the access door opening is arranged at a position above a bathtub), which also causes inconvenience and difficulty in cleaning and dredging.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides an improved zero-fall board same floor drainage concentrator for building that can make its further improvement perfect on the basis of the zero-fall board same floor drainage device of building that CN110725369A reported above to satisfactorily solve the not enough and problem that still exists in its use.

The utility model discloses the basic structure of zero board with layer drainage concentrator is fallen to modified building still keeps the basic structure design of zero board with layer drainage device that falls to building that CN110725369A reports, include setting up in the riser of both ends of pipeline central line and riser water outlet between the mouth of pipe, be equipped with the skew chamber section of riser of the central line skew of the water flow central line that link up the rivers passageway, be equipped with the horizontal branch pipe interface of sewage pipe that is used for connecting the toilet stool pot in this riser skew chamber section; a shared water seal chamber which is independent and provided with at least one waste water cross branch pipe joint for connecting waste water pipelines including a wash plate, a bathtub, a floor drain and the like is arranged in parallel with the vertical pipe offset cavity section; the shared water seal chamber and a water flow outlet of the vertical pipe offset chamber section are converged below the pipeline, and are connected to a vertical pipe water outlet pipe orifice along the lower section of the pipeline with the water flow central line consistent with the central line of the pipeline. The inlet and outlet section center lines of the elbow section are respectively consistent with the center line of the inlet water connecting pipe orifice and the water flow center line of the vertical pipe offset cavity section, and the sectional area of the outlet is larger than that of the inlet. After a smooth gradual change type transition elbow section with small cross-sectional area inlet and large outlet and smooth curvature is arranged between the water inlet connecting pipe orifice of the vertical pipe and the vertical pipe deviation cavity section deviated from the water flow central line for connection, the freely falling type vertically falling water flow discharged from an upper building can enter the vertical pipe deviation cavity section through the smooth elbow section with small smooth gradually changing large cross-sectional area of the flow passage in a baffling mode, the flow velocity of the water flow can be obviously reduced and the pressure can be relieved, and simultaneously, the drop head of the water flow of the vertical pipe and the pressure relief of the water flow of the vertical pipe can be reduced layer by layer from high to low along with the whole building, so that the drainage noise of the vertical pipe can be effectively reduced, and the service life of a drainage vertical pipe assembly. Tests show that the smooth gradual transition elbow section with smooth curvature can enable the drainage hydraulic working condition of the vertical pipe to reach the optimal state and the self-circulation ventilation to be smooth, so that the fluctuation range of the positive and negative pressure gas pressure in the drainage vertical pipe is reduced to the minimum value, and the liquid level of a water seal liquid column area in the drainage collector in each layer of building is effectively ensured to be always in a stable state.

On the basis of the structure, a first diversion clapboard which is sheltered outside the outlet of the water flow discharged by the shared water seal chamber in an overturning way and extends towards the direction of the total merged water flow can be further arranged at the merging part of the water flow which is discharged by the shared water seal chamber in an overturning way after passing through the water seal structure and vertically falls along the vertical pipe deflection cavity section, so that the mutual interference or the hedging between the water flow discharged by the shared water seal chamber in an overturning way and the vertically falling water flow at the water flow outlet part of the vertical pipe deflection cavity section can be avoided. Because the vertical falling of the discharged water along the public drainage vertical pipe in the high-rise building is free falling type high-flow impact water flow with acceleration, when the water flow transversely overturned and discharged by the shared water seal chamber in the layer is converged before being converted into the vertical water flow, the interference and the even water tongue formation can occur, so that the situations that the water flow of the vertical pipe flows back and flows back into the shared water seal occur. The confluence part of the water flow in different directions in the water flow outlet of the common water seal cavity and the vertical pipe offset cavity section is provided with a first diversion clapboard which can be sheltered outside the water outlet of the common water seal cavity and extends towards the direction of the converged total water flow, so that the waste water overturned and discharged by the common water seal cavity can be in a non-interfering diversion state with the water flow vertically falling along the vertical pipe offset cavity section before being converted into the vertical water flow from the transverse water flow, and then converged after both the waste water and the vertical water flow vertically falling in the same direction, thereby effectively avoiding the water tongue phenomenon which is possibly formed by the mutual interference and the opposite flushing of the water flows in different directions of the waste water and the vertical pipe downward offset cavity section, and also avoiding the phenomenon that the water flow of the vertical pipe downward offset cavity section of the vertical pipe overflows and flows.

Similarly, in the water flow channel position corresponding to the inner side opening of the sewage transverse branch pipe connector in the vertical pipe offset cavity section of the drainage collector, a second diversion baffle plate which is shielded outside the inner side opening of the sewage transverse branch pipe connector and extends towards the total combined water flow direction to avoid the mutual interference between the water flow flowing out of the sewage transverse branch pipe connector and the water flow falling vertically in the vertical pipe offset cavity section can be arranged, so that the water tongue phenomenon caused by the mutual interference and the opposite impact between the sewage water flow transversely discharged by the sewage transverse branch pipe and the water flow falling vertically in the vertical pipe offset cavity section from the high-rise building can be effectively avoided, and the phenomenon that the water flow falling vertically in the vertical pipe flows back and flows back into the sewage transverse branch pipe of the high-rise building can be avoided.

Because a plurality of wastewater transverse branch pipe joints are simultaneously connected in the common water seal chamber, the conditions of different types of wastewater are complex, the water flow is relatively slow, and sedimentation and clogging are easy to occur. The common water seal cavity is further convenient to clean and dredge, and other maintenance works, and a dredging conduit which extends outwards and is used for cleaning and dredging can be arranged above the common water seal cavity in the structure. The outward extending dredging pipe communicated with the common water seal chamber can effectively solve the problem that even if a non-professional dredging person is used, the conventional cleaning and dredging of the common water seal chamber can be performed when the height of an access door arranged on the wall of the pipeline well from the ground is more than 500 mm.

In addition, in the drainage collector, since the vertical pipe offset cavity section is a through water flow channel with a water flow central line offset from the central line of the pipeline, a non-circular water flow channel with a pipe diameter and a cross-sectional shape with different lengths and diameters can be adopted. At the moment, the sewage transverse branch pipe interface is arranged on the pipe wall where the long-diameter part of the non-circular section water flow channel is positioned, so that the sewage transverse branch pipe interface in the drainage collector and a toilet drainage sewage pipeline in a toilet are in the same direction, the bending degree of the connecting elbow can be effectively reduced, the water flow of the drainage pipeline is smoother and is not easy to block, the size of the internal space width of the decorative wall for shielding the drainage sewage pipeline can be reduced to the minimum, and the indoor clean use space is maximized.

Through the utility model discloses above-mentioned building after improving is zero falls board with layer drainage concentrator, can make this building of the same kind zero fall board with layer drainage concentrator's structure and effect more optimize and perfect, and the rivers that fall are more unobstructed when reducing drop height in making the riser, have reduced the air pressure fluctuation in the riser, ensure that the water seal is not destroyed to its life has been prolonged, the effect and the sensation of use are also better.

The above-mentioned aspects of the present invention will be further described in detail with reference to the accompanying drawings and examples. This should not be understood as limiting the scope of the above-described subject matter of the present invention to the following examples only. Various substitutions and alterations according to the general technical knowledge and conventional means in the field are included in the scope of the present invention without departing from the technical idea of the present invention.
