Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention the present invention is described in further detail.
The invention provides a kind of high speed motor car drainage arrangement, including collecting container and discharge pipe line 6, collecting container includes the cavity 15 in shell 14 and shell 14, cavity 15 is internal is separated into drain chamber 4 and intake antrum 2 by dividing plate 16, the siphon 3 being arranged on dividing plate 16 makes drain chamber 4 and intake antrum 2 through, the top of intake antrum 2 connects water inlet pipe 1, the top of drain chamber 4 connects the drain pipe import 5 of discharge pipe line 6 by water inlet tube interface 9, discharge pipe line 6 is positioned at outside collecting container, the drainpipe outlet 7 of discharge pipe line 6 end is positioned under the horizontal plane bottom described collecting container.
As in figure 2 it is shown, collecting container includes shell 14 and cavity 15, smooth use during for making drainage arrangement run in the winter time, heat-insulation layer can be set between shell 14 and cavity 15, utilize insulation material to play cold-proof effect.Housing 14 in intake antrum 2 correspondence has through hole with cavity 15 top, is used for connecting water inlet pipe 1, and water inlet pipe 1 communicates with the water-using structure of washroom, and the waste water produced in making washroom is entered in intake antrum 2 by water inlet pipe 1, and then discharges.
Cavity 15 is internal is divided into intake antrum 2 and drain chamber 4 two parts by dividing plate 16, dividing plate 16 is provided with siphon 3, intake antrum 2 is made to realize through with drain chamber 3 by siphon 3, and drain function, in the present embodiment, the product of the more conventional use of section of the siphon 3 used wants big, cross dimensions can select in the range of 20*20mm to 20*45mm, through lot of experiment validation, when cross dimensions is 20mm*40mm, the effect reducing drainage arrangement blocking frequency is best.For making drain chamber can retain mud and the foreign material of washroom waste water further, reduce cleaning and repair rate, the position that arranges of siphon 3 can be improved, the most in the present embodiment, siphon 3 arrange the more conventional product in position to arrange position on the upper side, to strengthen the distance of siphon 3 mouth of pipe and cavity 16 bottom surface, when in the range of siphon 3 mouth of pipe distance away from cavity 15 bottom surface and cavity 15 overall height are than at 1:3 to 1:4, effect is best.
Being provided with drain interface 9 at the cavity 15 of drain chamber 4 correspondence and the top of shell 14, the drain pipe import 5 with discharge pipe line 6 top is flexibly connected, and needs to ensure air-tightness at connection procedure.Discharge pipe line 6 is flexibly connected with drain interface 9 through drain pipe import 5, make discharge pipe line 6 through with drain chamber 4, discharge pipe line 6 downwardly extends after cavity volume top bending of catchmenting, below the horizontal plane of the bottom that its drainpipe outlet 7 is positioned at collecting container so that waste water can be discharged outside car smoothly.Discharge pipe line 6 arranges heat tracing structure, such as electric with worm line, solar energy heat tracing line, and other any heat tracing structures, start parcel from the end of discharge pipe line 6, effectively to realize heats, solve the problem that the discharge outlet of EMU drainage arrangement easily freezes.
In the present embodiment, discharge pipe line 6 is moved on to collecting container in drain chamber 4, the dischargeable capacity making drain chamber 4 increases, and due to water flow space between drain chamber 4 top need not reserved in collecting container and discharge pipe line 6, on the one hand under can meeting requirement condition ensureing pressure reduction, drainage arrangement overall height dimension can be made to diminish, achieve lightweight requirements, on the other hand, by increasing the dischargeable capacity of drain chamber 4, especially by the ratio rationally arranging intake antrum 2 and drain chamber 4, the drain chamber making drainage arrangement can retain washroom waste water, and retain the mud in waste water and foreign material, reduce cleaning and repair rate, when the volumetric ratio of intake antrum 2 with drain chamber 4 is about 3:2, the effect above is best.
The bottom of collecting container by screw 12 be fixed with bottom inspection cover 8, can drainage arrangement silting or other need situation to need repairing time, bottom inspection cover 8 is taken off, carry out necessity maintenance.For ease of maintenance, also for targetedly out of order position is keeped in repair, in the present embodiment, through hole can be provided with on the bottom inspection cover 8 that the drain chamber that silting often occurs is corresponding, by drain chamber draining screw plug 11, through hole is blocked, when need to keep in repair, drain chamber draining screw plug 11 is taken not, carry out the maintenance of necessity.Also can be installed into water cavity draining screw plug 10 on the bottom inspection cover 8 that intake antrum is corresponding simultaneously.By arranging drain chamber draining screw plug 11 and intake antrum draining screw plug 10, orientable drain chamber 4 and/or intake antrum 2 are oriented maintenance, take off without by whole bottom inspection cover 8, easy to maintenance simply.
Intake antrum 2 is a cavity the most airtight, for ensureing the air-tightness during normally using, sealing device can be set at each seam, as being provided with sealing ring between the through hole of water inlet pipe 1 and shell 14 and cavity 15, ensure the sealing property of seam, it is provided with sealing ring with corresponding through hole, to ensure the air-tightness of whole device at drain chamber draining screw plug 11 and intake antrum draining screw plug 10.
In sum, a kind of EMU drainage arrangement that the present invention provides, by being arranged on outside drainage arrangement by drain pipe, increase the volume of drain chamber, in the case of ensureing that pressure reduction meets condition, drainage arrangement whole height diminishes, it is achieved vehicle lightweight；Intake antrum and drain chamber ratio are rationally set, and increase the distance bottom siphon nozzle drainage arrangement, make drain chamber can retain the mud in the waste water of washroom and foreign material, reduce cleaning and repair rate；Rationally strengthen siphon section, reduce the blocking frequency of drainage arrangement；Discharge pipe line arranges heat tracing cold-proof, when solving winter operation, the problem that discharge pipe line outlet easily freezes；By arranging inspection cover bottom drainage arrangement, and draining screw plug, can clear up mud and foreign material to drainage arrangement easily.
As it has been described above, the plan content given by Jie Heing, similar technical scheme can be derived.In every case it is the content without departing from technical solution of the present invention, any simple modification, equivalent variations and modification above example made according to the technical spirit of the present invention, all still fall within the range of technical solution of the present invention.
