Description
Technical Field
[0001] The utility model relates to the technical field of building drainage, and particularly relates to a building drainage structure for houses. Background Art
[0002] Rainwater on the roof flows into the sewer through a vertical drainage pipe. Since there are some sundries such as leaves and branches on the roof surface, if these sundries enter the drainage pipe, they will cause blockage at the bent part of the drainage pipe. In winter, the drainage pipe will freeze, and the expansion of the ice cubes is likely to cause damage to the connection part of the drainage pipe. In order to prevent sundries from entering the drainage pipe, in the prior art, a filter screen is arranged at the top end of the drainage pipe, that is, the water inlet, to intercept these sundries. However, over time, these sundries accumulate at the filter screen, resulting in a decrease in the drainage volume. At that time, it is necessary to manually clean these sundries on the roof, which is very inconvenient, and there is a risk of climbing high manually. Content of the Utility Model
[0003] The purpose of the utility model is to provide a building drainage structure for houses to solve the above problems, as described in detail below.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0009] A lifting component is arranged on the drainage pipe for adjusting the height of the sliding sleeve.
[0010] By adopting the above building drainage structure for houses, the collection trough can collect the rainwater on the roof into the drainage pipe. The filter screen can block sundries such as leaves, preventing these sundries from entering the drainage pipe and causing blockage at the internal bending part of the drainage pipe.
[0011] When the leaves at the top of the filter screen accumulate to a certain extent, it will cause slow drainage. At this time, the sliding sleeve is moved upward through the lifting component, and the filter screen is driven upward by the sliding sleeve, so that the filter screen is flush with the upper end of the drain pipe. In this way, the accumulated leaves can be pushed out of the drain pipe, and then the driving component is used to rotate the scraper, and the sundries accumulated on the upper side of the filter screen can be scraped off by the scraper.

[0014] Preferably, the driving component includes a second rotating shaft and a torsion spring. The second rotating shaft is rotatably arranged on the drain pipe, and the length direction of the second rotating shaft is perpendicular to the length direction of the first rotating shaft. Bevel gears are fixed on both the first rotating shaft and the second rotating shaft, and the two bevel gears are meshed. The torsion spring is sleeved on the surface of the first rotating shaft, and both ends of the torsion spring are fixed to the fixing plate and the first rotating shaft respectively. A wire winding wheel is fixed on the surface of the second rotating shaft, and a second pull rope is fixed on the surface of the wire winding wheel. The second pull rope is wound around the wire winding wheel for several turns, and the end of the second pull rope away from the wire winding wheel is fixed with a second pull ring.
[0015] Preferably, a plurality of second guide sleeves are vertically distributed on the surface of the drain pipe, and the second pull rope passes through the second guide sleeves in sequence.
[0016] Preferably, the lifting component includes a first pull rope. An opening is formed on the surface of the drain pipe, and a movable plate is slidably arranged in the opening. The movable plate is fixed to the surface of the sliding sleeve. A guide rod is vertically slidably arranged on the movable plate. The upper end of the guide rod is fixed to the drain pipe through a fixing block. A spring is sleeved on the surface of the guide rod, and both ends of the spring are fixed to the fixing block and the movable plate respectively. A first pull rope is fixed on the movable plate. A wire guiding wheel is fixed on the surface of the drain pipe, and the wire guiding wheel is located above the movable plate.
