Description

Technical Field

[0001] This utility model belongs to the technical field of building drainage systems, specifically relating to a bottom inspection bypass pipe for drainage risers. Background Technology

[0002] Drainage risers (also known as vertical pipes) are the main pipes installed vertically in the drainage system. They are responsible for transporting sewage from the building's main pipes to drainage points on each floor or at different elevations, and finally into the outdoor pipe network.

[0003] In related existing technologies, such as Chinese Patent No. CN218713613U, a building domestic drainage riser with overflow function is disclosed. This riser includes a horizontal branch pipe, a drainage riser, a discharge pipe, an overflow horizontal pipe, an overflow riser, an overflow discharge pipe, and an overflow alarm. It is mainly used when the discharge pipe is blocked, causing the water level in the drainage riser to rise rapidly. When the water level reaches the connection between the overflow horizontal pipe and the drainage riser, sewage is discharged sequentially through the overflow horizontal pipe, overflow riser, and overflow discharge pipe to an outdoor inspection well. Simultaneously, the overflow alarm sends an alarm signal to notify professionals to clear the blocked discharge pipe in a timely manner. Drainage risers with overflow pipe systems prevent sewage from entering the building when the discharge pipe is blocked. They also have an overflow alarm function and are applied in the design and installation of domestic drainage systems in multi-story and high-rise buildings, improving the reliability of building drainage systems and the safety of indoor hygiene.

[0004] However, in actual use, during peak water usage periods, the water flow in the pipes is large, and the sewage that flows into the drainage riser may accumulate to a certain height in the drainage riser because it cannot be discharged in time. When this height exceeds the height of the overflow pipe, the sewage is discharged through the overflow pipe and triggers the overflow alarm. At this time, the drainage riser is not blocked, which means that the accuracy of the alarm function in the above device is poor and not conducive to actual use. Utility Model Content

[0005] The present invention aims to provide a bottom inspection bypass pipe for drainage risers to solve the problem of poor accuracy of the anti-clogging warning function of existing drainage risers mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bottom inspection bypass pipe for drainage risers, comprising...

[0007] The drainage riser body has an inclined inspection pipe installed on its outer wall. The top edge of the inspection pipe near the drainage riser body is lower than the bottom edge of the inspection pipe away from the drainage riser body.

[0008] A sealing cap is installed on the end of the inspection pipe furthest from the main body of the drain riser.

[0009] The bypass pipe body is installed on the inspection pipe and is located between the sealing cover and the drain riser body;

[0010] The detection alarm is installed on the sealed cover and located inside the inspection tube.

[0011] The principle and effects of this technical solution:

[0012] 1. By installing the detection alarm on the sealed cover, the horizontal height of the detection alarm is higher than that of the bypass pipe body. When the drainage riser body is not blocked and the drainage volume is large, the water flow will flow into the drainage riser body and then be discharged through the bypass pipe body. The dual drainage effect can effectively drain the water. Thus, under normal water flow conditions, sewage is unlikely to accumulate above the inspection pipe to trigger the detection alarm, thereby improving the alarm accuracy of the detection alarm.

[0013] 2. When the drainage riser is blocked and it is during peak water usage, the sewage accumulated in the drainage riser is too large to be drained immediately by the bypass pipe. As a result, the sewage will continue to spread into the inspection pipe until the detection alarm is triggered.

[0014] The present invention is further configured to include a filter assembly, which includes a filter plate and a control rod. The filter plate is slidably fitted inside the inspection tube, and the control rod is installed on the sealing cover and fixed to the filter plate.

[0015] The principle and effect of this technical solution: The filter plate can filter and block garbage and impurities when sewage overflows, thereby preventing garbage and impurities from entering the bypass pipe or inspection pipe during overflow and causing blockage of the bypass pipe or inspection pipe, thus ensuring the water flow effect of the inspection pipe and bypass pipe when the drainage riser is blocked.

[0016] The present invention is further configured such that: the filter assembly also includes a control head, the control rod is threadedly engaged with the sealing cover, and the end of the control rod extends outside the sealing cover and is fixed to the control head.

[0017] The principle and effect of this technical solution: The control head drives the control rod to rotate, which in turn moves the filter plate relative to the inspection tube, thereby adjusting the position of the filter plate relative to the bypass pipe body. This allows the sealing cover to control whether larger debris can enter the bypass pipe body without opening it.

[0018] The present invention is further configured such that: the bypass tube body has a transparent observation section at one end near the inspection tube, and a shielding component is movably installed on the outside of the observation section.

[0019] The principle and effect of this technical solution: By setting up the observation section, workers can observe the water flow in the bypass pipe body through the observation section when dredging the pipeline, so as to avoid the situation where sewage flows out from the sealing cover of the inspection pipe after the worker opens the sealing cover. Furthermore, by setting up the shielding component, the observation section can be shielded by the shielding component when it is not necessary to observe the water flow in the bypass pipe body, so as to avoid the flow of sewage affecting the residents' visual experience.

[0020] The present invention is further configured such that: the shielding component includes a first collar, a second collar, a first baffle, and a second baffle. The cross-sections of the first baffle and the second baffle are both semi-circular arcs, and the inner diameter of the second baffle is not less than the outer diameter of the first baffle. The outer diameter of the observation section is the same as the inner diameter of the first baffle. The first collar is fixedly fitted onto the outer wall of the observation section. The first baffle is fixed onto the outer wall of the first collar and abuts against the observation section. The second collar is rotatably installed on the outer wall of the first baffle and is located at the end of the first baffle away from the first collar. The second baffle is fixed onto the side wall of the second collar, and the end of the second baffle abuts against the side wall of the first collar.

[0021] The principle and effect of this technical solution: The observation section is enclosed by two semi-circular arc-shaped first and second baffles of different sizes, which can achieve the effect of shielding the observation section. Furthermore, by allowing the second ring to rotate relative to the first baffle, the second baffle can overlap and be stored with the first baffle through rotation, thereby exposing part of the observation section so that the staff can observe the water flow status of the bypass pipe body. The setting of fixing the first ring to the outer wall of the observation section can ensure the positional stability of the shielding component relative to the observation section.

[0022] The present invention is further configured such that: the outer wall of the first baffle has an arc-shaped protrusion, the inner wall of the second ring has a groove, the arc-shaped protrusion and the groove slide together, and the first baffle abuts against the inner wall of the second ring.

[0023] The principle and effect of this technical solution: By setting the arc-shaped protrusion and groove, the second ring can be rotated and fitted outside the first baffle without falling off, thus ensuring the positional stability of the second ring relative to the first baffle.

[0024] The present invention is further configured such that: a connecting plate is fixed on the outer wall of the second baffle, a limiting bolt is threadedly inserted on the connecting plate, a limiting groove is opened on the outer wall of the first collar, and the end of the limiting bolt abuts in the limiting groove.

[0025] The principle and effect of this technical solution: By rotating the limiting bolt, the distance between the end of the limiting bolt and the limiting groove can be changed, so that the limiting bolt is pressed against the limiting groove or away from the limiting groove. The frictional force of the contact stabilizes the position of the connecting plate, thereby enabling the second baffle to maintain a stable position. Attached Figure Description
