Description

Technical Field

[0001] This utility model relates to the field of industrial technology, and in particular to a sewage pipeline branch port. Background Technology

[0002] The sewage pipeline branch point is a key structure in the integrated utility tunnel for handling gravity-flow sewage access. Its core design lies in locally raising the non-sewage compartments within the tunnel, forming a double-layer space with an upper integrated pipeline compartment and a lower sewage pipe-penetrating layer. The sewage compartment independently maintains its original elevation and is equipped with inspection wells. The well walls are pre-embedded with longitudinal and transverse through-wall sleeves for sewage pipes to pass through. The side walls of the pipe-penetrating layer are also pre-reserved with transverse sleeves to allow external sewage pipes to be introduced from the side of the tunnel. This structure avoids the conflict between the elevation of the sewage gravity flow system and the elevation of the tunnel, while ensuring that the functions of other pipelines do not interfere with each other when the sewage branch pipe is connected. The inspection well is equipped with a ladder, manhole, and ventilation hole for easy inspection and maintenance. The overall design takes into account both the reasonable layout of pipelines and the needs of sewage entering the tunnel.

[0003] A search revealed Chinese patent publication number CN217128433U9, which discloses a sewage pipeline branch port. The water supply pipe is equipped with a valve, and a switch is located on one side of the valve. The water supply pipe has a threaded groove inside, which is threaded onto a threaded protrusion. A filter is fixedly connected below the threaded protrusion. The filter has a first filter layer inside, with sieve holes on the first filter layer. A second filter layer is located below the first filter layer. A reverse threaded protrusion is located below the filter and is threaded onto the threaded groove inside the drain pipe. This utility model effectively filters impurities in sewage by using a filter on the sewage pipeline. A pressure sensor and alarm device inside the water pipe can determine the location of the blockage. During maintenance and cleaning, only the filter needs to be replaced to solve the blockage problem, making maintenance and cleaning quick and efficient. However, in actual use, the above device has a problem with an unreasonable sealing structure design, leading to sewage leakage and pollution of surrounding soil or groundwater. Therefore, a sewage pipeline branch port is proposed to solve the above problems. Utility Model Content

The first fixing button 804 is used to improve the stability of the damping mechanism 8 and can be disassembled at any time for easy maintenance of the damping mechanism 8.

[0045] Specifically, the core component of the shock-absorbing mechanism 8 is the chassis 801, which serves as the foundation of the entire mechanism. The bottom of the chassis 801's outer wall is directly connected to the top of the outer wall of the first tube 1. A vertical flange post 802 is installed on the inner wall of the chassis 801. A first fixing button 804 is fitted on the top of the outer wall of the flange post 802. The top plate 803 is slidably engaged with the outer wall of the flange post 802.

[0046] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the first tube 1 is fixedly connected to a first fixing member 9, and the outer wall of the first tube 1 is fixedly connected to a second fixing member 10.

[0047] Specifically, the surface of the first tube 1 is fitted with a first fixing member 9, and the surface of the tube is also connected to a second fixing member 10. The first fixing member 9 is responsible for firmly positioning the left side of the tube, while the second fixing member 10 is responsible for fastening the right side of the tube, so that the tube is evenly supported. The surface of the flange column 802 slides into the internal space of the spring 805, forming a rotational fit between the two. The outer surface of the bottom of the spring 805 is fixedly connected to the top surface of the second fixing button 8061.

[0048] Working principle: First, the sealing airbag 301 undertakes the task of sealing and strengthening the pipe connection. The right side of the airbag is connected to the inflation column 302. The inflation column 302 works in conjunction with the guide column 4 to guide and deliver external gas into the internal space of the sealing airbag 301. The surface of the rotating rod 3041 is installed in the internal channel of the threaded column 501 by a threaded engagement. The right end of the rotating rod 3041 is fixedly equipped with a knob 3042. The operator can drive the rotating rod 3041 to perform a rotating and pushing action by rotating the knob 3042, gradually introducing the gas into the cavity of the sealing airbag 301 through the inflation column 302. Finally, the continuous filling of gas causes the sealing airbag 301 to expand and deform, thereby effectively enhancing the sealing effect at the pipe connection. This device fully realizes the efficient sealing function at the pipe connection seam.

[0049] Furthermore, the chassis 801 is the supporting base of the system, and its bottom surface is directly connected to the upper surface of the first pipe body 1. The upper surface of the flange column 802 is equipped with a first fixing button 804, and the bottom surface of the flange column 802 is provided with a second fixing button 8061. The second fixing button 8061 is firmly attached to the bottom end of the column. The outer surface of the second pipe body 6 is specially configured with an arc surface 8062 to correspond to it. The flange column 802 undertakes a dual function, serving as both a directional sliding track for the top plate 803 and providing reliable support for the buffer stroke of the top plate 803. The spring 805 is the core functional element of the entire damping mechanism 8. When the pipeline vibrates, it plays a role in damping and dissipating vibration through elastic deformation. The coordinated work of the entire combined device realizes the vibration buffer protection of the pipeline joint area.
