Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 2, the present invention provides a technical solution:
a backflow-preventing emergency drainage device for an underground building comprises a submersible pump and pipelines, wherein the pipelines comprise a front pipeline, a modified pipeline 9 and a rear pipeline which are sequentially connected from front to back, the initial end of the front pipeline is connected with the submersible pump, the tail end of the rear pipeline is connected with a sewage well 10, a check valve 4 is installed on the modified pipeline, and the height of the check valve is higher than that of the outlet end of the modified pipeline; and the improved pipeline is also provided with a water pumping pipeline connector 2.
The water pumping pipeline connecting port 2 is provided with an interface sealing cover 3. When emergency drainage is not performed at ordinary times, the opening is sealed for a long time.
The water pumping pipeline connecting port is positioned in front of the check valve. For emergency drainage.
The pipeline is anti-u type pipeline or inverted u type pipeline, the end of u type pipeline is up promptly, mouthful structural shape down, anti-u type pipeline connects gradually by preceding bending section 1, horizontal segment, back bending section 5 and constitutes, the back half position at the horizontal segment is installed to the check valve, the pumping line connector is seted up in the first half position at the horizontal segment.
The initial end of the front bending section of the inverted u-shaped pipeline is a modified pipeline inlet end, the tail end of the rear bending section is a modified pipeline outlet end, and the modified pipeline inlet end and the modified pipeline outlet end are the same in height.
The interface sealing cover is used for sealing and blocking the water pumping pipeline connecting port. The sealing cover can be sealed in a mode of a thread with a rubber ring, for example, an external thread is arranged on the connector in an upward protruding mode, an internal thread is arranged inside the sealing cover, a sealing ring is arranged on the inner wall of the sealing cover, and then the sealing cover is screwed on the water pumping pipeline connector.
The inlet end of the improved pipeline is connected with a front pipeline, the front pipeline is connected with a submersible pump in a drainage pool of an underground building, the outlet end of the improved pipeline is connected with a rear pipeline, and the rear pipeline is communicated with an underground sewage well.
And the horizontal section of the inverted u-shaped pipeline is higher than the outdoor terrace. The emergency drainage is convenient, the check valve is convenient to maintain and replace, and the like.
The anti-U-shaped bend is a galvanized steel pipe, improves the sewage defense ability of flowing backward through improving the local height of the pipeline, and the U-shaped bend section of bending down can not rise to the position of the check valve because of the height difference that most granular impurities in the external sewage can be deposited due to gravity factors, and under the normal closed state of the check valve, the check valve and the flowing backward water form a high-pressure state, thus increasing the difficulty of backflow. Under daily use conditions, the U-shaped bent upper device is in a dry state, so that the service life of the device is prolonged.
The water suction pump interface is located the curved top of anti U type, mainly connects outside water suction pump, and the interface is high-power water suction pump general interface, also can regard as the simple and easy inspection mouth of check valve.
The check valve sets up in the suction pump rear end, (can cancel if the former check valve that has set up in the underground in the original scheme, certainly also can not cancel, and do not influence the use), mainly be used for preventing outside sewage from flowing backward, the check valve piece relies on gravity can self return, need not to maintain under the normal condition. The emergency drainage device can automatically block external water from flowing back during emergency drainage, and does not need to be singly provided with a valve to be closed. The check hole is arranged at the upper part of the check valve, so that the check valve can be checked and maintained.
The modified duct 9 in fig. 2 is the detailed structure of fig. 1. The original check valve is cancelled, an inverse U-shaped bend is arranged at the position of outdoor dispersed water, and an external water suction pump connector and the check valve are sequentially connected to the upper part of the U-shaped bend. A section of the original pipeline is cut off, and the device shown in figure 1 is installed.
When outside sewage water level rose, because of there being the difference in height during sewage flows backward, reach the large granule deposit behind the down-turned section, the water level continues to rise to the check valve position, forms local high-pressure sewage unable the passing through because of the check valve is closed and gas compression.
When the drainage works in an emergency state, the water flow check valve acts consistently to block external sewage, and accumulated water in the building can be discharged outwards only through one-way flow.
In the description of the present invention, it should be understood that the orientation indication or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for convenience of description of the present invention, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.
