Description

Technical Field

[0001] The utility model belongs to the technical field of water supply and drainage pipes, in particular to a soft-connected shock-proof drainage pipe. Background Art

[0002] In essence, building seismic isolation is to separate the upper structure and the lower structure through the installation of seismic isolation devices, thereby blocking the channel for earthquake energy to be transmitted to the upper level. When an earthquake occurs, a large displacement will occur between the upper and lower structures of the building. At this time, in order to prevent the building's water supply and drainage pipes from being torn off during the displacement of the upper and lower structures, it is necessary to flexibly lay the water supply and drainage pipes passing through the seismic isolation layer in accordance with the requirements of the national standard GB50011, so that the water supply and drainage pipes passing through the seismic isolation layer can adapt to the horizontal displacement of the upper and lower structures of the building. However, when the pipes are flexibly laid, the flexible sections will inevitably have shear displacements, causing the flexible sections to be damaged under long-term water flow impact, reducing the service life of the pipes. Utility Model Content

[0003] The purpose of the utility model is to provide a soft-connected shock-proof drainage pipe to solve the problems raised by the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a soft-connected shockproof drainage pipe, comprising a rigid pipe and a flexible pipe fixedly connected between the rigid pipes, the flexible pipe comprising a hose and a buffer pipe fixedly connected to the water inlet end of the hose, a buffer wheel fixedly connected inside the buffer pipe, the buffer wheel comprising a wheel axle and an impeller rotatably connected to the wheel axle, the wheel axle comprising a main shaft and a telescopic shaft sleeved on both ends of the main shaft, and the main shaft and the telescopic shaft are fixedly connected by a spring fixedly connected to the end face of the main shaft, and the end of the telescopic shaft is clamped in a groove set inside the buffer pipe.

[0005] A buffer tube is arranged at the water inlet of the flexible pipe, and an impeller is arranged in the buffer tube which can rotate with the impact of the water flow. The rotation of the impeller can reduce the impact force of the water flow in the pipeline, and reduce the erosion of the water flow on the inner wall of the flexible pipe when the flexible pipe is sheared and displaced.

[0006] Furthermore, a plurality of through holes are arranged on the blade surface of the impeller; the through holes are arranged on the impeller to improve the efficiency of water flow passing through the buffer tube.

[0007] Furthermore, a screen is provided at the water inlet of the rigid pipe; the screen is provided to prevent large debris from entering the pipe and clogging the pipe.

[0008] Furthermore, the ends of the flexible pipe and the rigid pipe are detachably connected via flanges; the detachable connection facilitates pipeline maintenance.

[0009] Furthermore, the hose is a corrugated tube; the corrugated tube can be selected from mature products on the market to ensure the service life of the pipeline.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model uses a buffer tube arranged at the water inlet of the flexible tube, in which an impeller which can rotate with the impact of the water flow is arranged. The rotation of the impeller can reduce the impact force of the water flow in the pipeline, reduce the erosion of the water flow on the inner wall of the flexible tube when the flexible tube is sheared and displaced, and effectively prolong the service life of the pipeline.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 5The utility model provides a technical solution: a soft-connected earthquake-proof drainage pipe, comprising a rigid pipe 1 and a flexible pipe 2 detachably connected between the rigid pipes 1 through a flange 24. In order to prevent the flexible pipe 2 of the drainage pipe from shearing and displacement due to displacement of the upper and lower parts of the earthquake-proof layer when the pipeline passes through the earthquake-proof layer of the building, and the flexible pipe 2 is damaged by the large impact intensity of the water flow, the flexible pipe 2 of the utility model comprises a bellows 22 and a buffer pipe 21 fixedly connected to the water inlet end of the bellows 22, a buffer wheel 23 is clamped inside the buffer pipe 21, the buffer wheel 23 comprises a wheel shaft and an impeller 231 rotatably connected to the wheel shaft, the wheel shaft comprises a main shaft 232 and a telescopic shaft 233 sleeved on both ends of the main shaft 232, and the main shaft 232 and the telescopic shaft 233 are fixedly connected by a spring 234 fixedly connected to the end face of the main shaft 232, and the end of the telescopic shaft 233 is clamped in a groove set inside the buffer pipe 21.

[0020] In this embodiment, in order to improve the efficiency of water flow through the flexible pipe 2, a plurality of through holes 2311 are provided on the blade surface of the impeller 231, and in order to prevent large debris from entering the drain pipe and clogging the drain pipe or damaging the impeller 231, a screen 3 is provided at the water inlet of the rigid pipe 1.

[0021] During the specific implementation process, when installing the buffer wheel 23 of the utility model, it is only necessary to align the two ends of the buffer wheel 23 with the grooves in the buffer tube 21 and push it in from the entrance of the buffer tube 21. During the pushing process of the buffer wheel 23, the spring 234 between the main shaft 232 and the telescopic shaft 233 is compressed, and the connecting part of the telescopic shaft 233 and the main shaft 232 is retracted into the main shaft 232. When the end of the telescopic shaft 233 reaches the groove in the buffer tube 21, the spring 234 rebounds to make the telescopic shaft 233 clamped in the groove of the buffer tube 21, completing the installation of the buffer wheel 23. Finally, the flexible pipe 2 is fixed to the rigid pipe 1 through the flange 24 to complete the assembly of the drainage pipe.

[0022] It should be noted that the bellows 22 is a commercial component purchased on the market, and its specific model specifications need to be selected and determined based on the actual specifications of the device. The selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0023] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
