Description

Technical Field

[0001] The utility model relates to the technical field of building drainage, in particular to a downpipe structure. Background Art

[0002] As is known, a downpipe is a part of a pipe system in a building for discharging rainwater and sewage. It is usually installed near the outer wall or column of the building to guide water from the roof or other parts to the sewer or drainage system to prevent water from accumulating around the building and avoiding flooding and damage. As shown in the Chinese utility model with announcement number CN219175686U, a downpipe usually includes a flared rainwater collection part and a straight drainage part. In order to fit the outer wall, an elbow is also added to adjust the position of the drainage pipe. However, when a temporary color steel plate roof is constructed, the existing downpipe structure has the following defects: first, it cannot be quickly installed and adjusted according to the temporary building structure; second, a vortex may be formed when water falls, which is not conducive to the rapid discharge of rainwater and causes a greater load-bearing risk to the temporary building.

[0018] Combined with Figure 1 The downpipe structure comprises a water collecting pipe section 1, a transition pipe section 2, an adjustment pipe section 3 and a downpipe section 4 which are connected in sequence from top to bottom; a connecting plate 5 is fixed to one side of the upper end of the water collecting pipe section 1, and the connecting plate 5 fixes the upper end of the downpipe at the downpipe to avoid damage to the pipe body by traditional clamps; according to needs, two connecting plates 5 are provided and symmetrically fixed on both sides of the upper end of the water collecting pipe section 1, and the plate surface of the connecting plate 5 is provided with connecting holes. For the structure in which the bottom of the transverse groove is opened for water discharge, the two connecting plates 5 can be firmly clamped on the outside of the two groove walls of the transverse groove, and screws are screwed in the connecting holes to fix them to the transverse groove; the water collecting pipe section 1 is set to a cone with an upper end larger than a lower end, and the pipe wall of the water collecting pipe section 1 is provided with The edges can prevent the water flow from forming a stable vortex due to the structure of the conical water collecting pipe section 1. A diverter plate 8 is provided in the center of the inner cavity of the transition pipe section 2. The diverter plate 8 is used to divert the flow to eliminate the formation of vortices and increase the launch speed; the adjustment pipe section 3 is used to adjust the parallel spacing between the transition pipe section 2 and the downcomer pipe section 4. Specifically, the adjustment pipe section 3 can be set as a flexible structure to facilitate the adjustment of the position of the downcomer pipe section 4, or as needed, a first bend pipe section 6 is connected between the transition pipe section 2 and the adjustment pipe section 3, and a second bend pipe section 7 is connected between the adjustment pipe section 3 and the downcomer pipe section 4. The adjustment pipe section 3 is set as an axially telescopic folding structure, similar to a hard corrugated pipe, and the connection is more stable and can better withstand the impact of water flow.

[0019] To implement the downpipe structure of the utility model, it is only necessary to match the upper end of the water collecting pipe section 1 to the building drain outlet, and then use the connecting plate 5 to fix it to the drain structure, and then adjust the pipe section 3 to adapt it so that the drain pipe section 4 can be fixed to the wall. Embodiment 2:

[0020] When the water is discharged in the open air, there will be some debris impact, and the water collection pipe section is larger at the top and smaller at the bottom, which may cause blockage near the transition pipe section. When the water flow is slow, it cannot be flushed in time. Therefore, based on the first embodiment, as shown in the attached Figure 2 , 3As shown, two coaxial corresponding rotating shafts 9 are rotatably installed on the two side walls of the transition pipe section 2, and the inner ends of the two rotating shafts 9 are respectively fixedly connected to the middle parts of the two sides of the diverter plate 8, and the outer end of one of the rotating shafts 9 is connected to a screw handle 10 for rotating the diverter plate 8 so that the plate surface of the diverter plate 8 can be parallel to the axis of the transition pipe section 2 in a diverting state, or perpendicular to the axis of the transition pipe section 2 in a blocking state, that is, when the downpipe is blocked, the screw handle 10 can be turned to scrape the foreign matter from the diverter plate 8 to make it fall. If the blockage is above or below, the diverter plate 8 can be adjusted to the blocking state so that the water flow gathers in the water collecting pipe section 1, and then the diverter plate 8 can be adjusted to the diverting state so that the gathered water flow can rush down at once, and the blockage is washed away by water pressure;

[0021] As needed, the screwing handle 10 is set to be a long strip parallel to the diverter plate 8. A positioning plate 11 fixed to the outer wall of the transition pipe section 2 is provided outside the rotation range of the screwing handle 10. The positioning plate 11 is provided with a screw hole for screwing a positioning screw 12. The nail head of the positioning screw 12 can resist the screwing handle 10 to keep the diverter plate 8 in the diverter state. Because the diverter state is normal, the positioning screw 12 is required for positioning. When the diverter plate 8 needs to be adjusted and rotated, it is only necessary to unscrew the positioning screw 12; in addition, mounting holes are symmetrically provided in the middle of the two side walls of the transition pipe section 2, and sealing plugs 13 are detachably installed in the mounting holes. The two rotating shafts 9 are respectively rotatably installed on the two sealing plugs 13, and the inner ends of the two rotating shafts 9 are detachably connected to the corresponding sides of the diverter plate 8, which is convenient for quick disassembly and installation.
