Description

Technical Field

[0001] The utility model relates to the technical field of building drainage, in particular to a dredging and drainage structure for building water supply and drainage pipes. Background Art

[0002] Outdoor stairs are affected by rain during use, causing rainwater to disperse on the surface of the stairs, thereby reducing the anti-slip effect of the stairs. When draining, the stairs flow from the upper end to the lower end of the ramp, affecting the normal walking of pedestrians. Therefore, it is necessary to use a drainage structure to effectively drain the stairs. However, the existing building staircase drainage structure still has certain defects during use.

[0003] For example, a self-draining staircase structure proposed in application number CN202320383597.7 includes multiple step groups, and the multiple step groups include pedals and risers. The pedals are arranged vertically to the risers, and the pedals are arranged above the risers. Drainage grooves are opened on the sides of the pedals and the risers, and the drainage grooves supply water flow. A guide assembly is provided on the pedals, and the guide assembly is used to drain water into the drainage grooves. During actual use, rainwater is directly discharged into the interior of the drainage grooves through the water diversion grooves and the guide grooves. Rainwater will bring debris into the interior of the drainage grooves, which can easily cause blockage of the drainage grooves, thereby reducing the drainage effect during subsequent repeated use.

[0004] Therefore, we propose a dredging and drainage structure for building water supply and drainage pipes in order to solve the problems raised above. Utility Model Content

[0014] Preferably, the engaging rod and the connecting plate form a limiting telescopic structure through a spring and a limiting plate, and the engaging rod is engaged with the top of the drainage trough through a engaging groove.

[0015] The above-mentioned structural design facilitates the fixed connection and separation of the drainage trough and the filter trough through the connecting mechanism, which is beneficial for disassembling and cleaning the filter trough when debris is stuck inside the side filter holes and top filter holes of the filter trough and is inconvenient to handle, thereby improving the convenience of disassembly and cleaning of the filter trough.

[0016] Preferably, the anti-clogging mechanism includes an interlocking groove opened at the top of the water collection tank, the interior of the interlocking groove is movably connected to a filter plate, the interior of the filter plate is provided with through holes at equal intervals, the side of the filter plate close to the drainage tank is provided with a docking groove, the inner side of the filter plate is provided with limiting holes at equal intervals, the interior of the limiting hole is slidably connected to a limiting rod, and the bottom end of the limiting rod is fixedly connected to the top surface of the interlocking groove.

[0017] Preferably, the size of the limiting hole matches the size of the limiting rod, and the filter plate is connected to the fitting groove in a limiting manner through the limiting hole and the limiting rod.

[0018] The above-mentioned structural design facilitates effective protection of the water collection tank through the anti-clogging mechanism, avoiding blockage when rainwater enters the water collection tank, and is beneficial for the anti-clogging mechanism to filter the rainwater entering the water collection tank. At the same time, it is beneficial for convenient cleaning when the anti-clogging mechanism is disassembled, further improving the convenience of cleaning.

[0019] Compared with the prior art, the beneficial effects of the present invention are: the dredging and drainage structure of the building water supply and drainage pipes;

[0020] 1. The drainage ditches opened at equal intervals on the slope can intercept and guide the rainwater flowing from top to bottom and collect it in the drainage trough. The setting of the drainage trough can also cooperate with the inclined setting of the stair tread surface to collect the rainwater in the drainage trough. The collected rainwater can be discharged into the sump for subsequent centralized discharge, thereby improving the effect of rainwater collection.

[0021] 2. The setting of the connecting mechanism can fixedly connect and separate the filter tank and the drainage tank, which is beneficial for the filter tank to use the side filter holes and the top filter holes to effectively filter and collect rainwater on the slope and stair treads during installation, thereby preventing debris in the rainwater from clogging the drainage tank. At the same time, the setting of the anti-clogging mechanism can effectively filter the rainwater entering the water collection tank, thereby avoiding clogging the water collection tank, thereby improving the anti-clogging effect of the dredging and drainage structure of the building's water supply and drainage pipes.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-5 The utility model provides a technical solution: a dredging and drainage structure for building water supply and drainage pipes, comprising a stair tread 1, a mounting groove 2 symmetrically opened in the middle of the stair tread 1, a drainage groove 3 installed inside the mounting groove 2, the drainage groove 3 being arranged obliquely, a filter trough 9 movably installed on the top of the drainage trough 3, side filter holes 10 being evenly spaced on both sides of the filter trough 9, a top filter hole 11 being evenly spaced on the top of the filter trough 9, a slope 12 being fixedly installed in the middle of the stair tread 1, and drainage grooves 13 being evenly spaced on the surface of the slope 12;

[0030] The design of the above structure ensures that when rainwater falls on the slope 12, it will flow downward along the slope 12, and cooperate with the drainage ditch 13 to intercept it during the flow. The intercepted rainwater will be diagonally guided into the drainage grooves 3 on both sides through the drainage ditch 13, and will cooperate with the filter tank 9 and the top filter hole 11 to filter before entering the drainage groove 3, so as to prevent debris in the rainwater from entering the drainage groove 3 and causing blockage. When rainwater falls on the stair treads 1, it will follow the oblique setting of the surface of the stair treads 1 to guide it into the drainage groove 3, and can cooperate with the filter tank 9 and the side filter hole 10 to filter, so as to prevent debris in the rainwater from entering the drainage groove 3 and causing blockage, thereby improving the anti-blocking effect of the drainage structure.

[0031] The filter tank 9 is connected to the drainage tank 3 through a connecting mechanism. The connecting mechanism includes a limit plate 4 symmetrically installed at the bottom of the filter tank 9. A locking rod 5 slides through the interior of the limit plate 4. A connecting plate 6 is fixedly connected to the inner side of the locking rod 5. A spring 7 is provided on the outer ring of the locking rod 5 between the connecting plate 6 and the inner side of the limit plate 4. The locking rod 5 and the connecting plate 6 form a limiting telescopic structure with the limit plate 4 through the spring 7. Locking grooves 8 are opened on both sides of the top of the drainage tank 3. The locking rod 5 is connected to the top of the drainage tank 3 through the locking grooves 8.

[0032] The design of the above structure enables the locking rod 5 to be extended and retracted inside the limit plate 4 by pulling the connecting plate 6 inward or the spring 7 pulling the connecting plate 6 back, thereby facilitating the control of the locking rod 5 and the locking groove 8 to be engaged and separated, which is beneficial for fixing the filter tank 9 and the limit plate 4 on the top of the drainage tank 3 when engaged, so that the filter tank 9 can effectively filter impurities in the rainwater, and is also beneficial for quickly disassembling the filter tank 9 and the limit plate 4 when separating, so as to facilitate the convenient cleaning of the debris remaining in the side filter hole 10 and the top filter hole 11 of the filter tank 9 after disassembly, thereby improving the cleaning convenience.

[0033] A stair platform 14 is fixedly installed at the bottom end of the stair tread 1, and a water collection trough 15 is provided on the top surface of the stair platform 14. An anti-blocking mechanism is installed on the top of the water collection trough 15. The anti-blocking mechanism includes a fitting groove 16 provided at the top of the water collection trough 15. A filter plate 17 is movably connected inside the fitting groove 16. Through holes 18 are provided inside the filter plate 17 at equal intervals. A docking groove 19 is provided on the side of the filter plate 17 close to the drain groove 3. Limiting holes 20 are provided on the inner side of the filter plate 17 at equal intervals. A limiting rod 21 is slidably connected to the inner side of the limiting hole 20. The bottom end of the limiting rod 21 is fixedly connected to the top surface of the fitting groove 16. The size of the limiting hole 20 matches the size of the limiting rod 21. The filter plate 17 is connected to the fitting groove 16 in a limiting manner through the limiting hole 20 and the limiting rod 21.

[0034] The design of the above structure allows rainwater to directly enter the water collection tank 15 through the docking groove 19 on the filter plate 17 when it enters the interior of the water collection tank 15 through the drainage trough 3, thereby improving the efficiency of rainwater filtered in the drainage trough 3 entering the interior of the water collection tank 15, and the filter plate 17 can use the limiting hole 20 opened inside to movably engage with the inside of the interlocking groove 16 and the outer circle of the limiting rod 21, so as to ensure the stability of the filter plate 17 during installation and prevent deviation and shaking. At the same time, the movable engagement method also facilitates disassembly and cleaning. The through hole 18 at the top of the filter plate 17 can filter and collect rainwater on the stair platform 14, thereby preventing debris in the rainwater from entering the water collection tank 15 and causing blockage, further improving the anti-blocking effect.
