Description

Technical Field

[0001] The utility model relates to the technical field of drainage facilities, in particular to an anti-blocking type drainage device for a building. Background Art

[0002] When a house is built, drainage facilities will be added to the outside of the house to drain rainwater from the roof into the ground, thereby avoiding excessive water accumulation on the roof. Usually, a vertical drain pipe is fixed to the side of the house with a clamp, and a connected water pipe is fixed at the upper end of the drain pipe. The water on the roof flows into the water pipe and then drains into the drain pipe.

[0003] However, traditional drain pipes and water pipes do not have a filtering mechanism, and the leaves and branches on the roof will clog the upper drain outlet of the drain pipe, thereby affecting the drainage efficiency. In addition, the leaves that fall on the drain pipes and water pipes cannot be cleaned up in time, causing the leaves to rot and change smell, affecting the environment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an anti-blocking type drainage device for building construction, which solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a blockage-proof house building drainage device, including a drain pipe and a water pipe, the water pipe is vertically connected to the drain pipe and connected, the upper end of the water pipe is provided with an opening, and also includes: a drainage piece, the drainage piece is arranged at the lower end of the water pipe, a branch channel is opened on the water pipe, the branch channel is connected to the upper end of the drainage piece, and the lower end of the drainage piece is connected to the side of the drain pipe; a filter piece, the filter piece is arranged in the opening, and the filter piece is arranged between the branch channels on both sides, and can prevent foreign matter from entering the drain pipe through the filter piece.

[0006] Furthermore, the drainage piece includes: an extension box, a conduit is fixedly connected to the lower end of the extension box, a collecting box is connected between the conduits, a filter is fixedly connected inside the collecting box, the upper end of the filter is located on one side of the conduit, and the lower end of the filter is located on the other side of the conduit, and a plug is provided at the lower end of the collecting box.

[0007] Furthermore, the filter element includes an end cover, and filter plates are fixedly connected to both sides of the end cover, and the filter plates are matched and connected with the water pipe.

[0008] Furthermore, a hook is fixedly connected to the lower end of the plug, and the edge of the plug is matched with the lower edge position of the filter.

[0009] Furthermore, both sides of the upper end of the end cover are inclined.

[0010] Furthermore, the collection box is transparent.

[0011] Compared with the above-mentioned background technology, the anti-blocking house building drainage device provided by the present application includes a drainage device with very mature technology today, and core components with drainage pieces and filter pieces. Its principle relies on that when the flow rate is small, water flows into the drain pipe from both sides through the drainage piece, and when the flow rate is large, foreign matter is filtered out through the combination of the drainage piece and the filter piece, thereby avoiding blockage of the drain pipe and the water pipe.

[0012] The utility model provides an anti-blocking type drainage device for building construction. Compared with the prior art, it has the following beneficial effects:

[0013] The anti-blocking house building drainage device can adapt to different water flow rates by arranging drainage components and filtering components according to different water flow rates, and can filter foreign matter on the outside of the drainage pipe and conduit during drainage to avoid drainage blockage, thereby improving the drainage efficiency of the water flow.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3The utility model provides a technical solution: a blocking-proof drainage device for house buildings, comprising a drainage pipe 1 and a water guide pipe 2 which are vertically connected and communicated with each other. An opening 3 is provided at the upper end of the water guide pipe 2. By setting a drainage piece and a filter piece, branch channels 4 are provided on both sides of the water guide pipe 2. When the flow rate is small, rainwater is directly directed to flow into the collection box 7 through the guide pipe 6 and the expansion box 5 through the branch channel 4. Foreign objects such as leaves will flow into the collection box 7 through the branch channel 4. The foreign objects will stay in the expansion box 5. Then smaller foreign objects will flow into the collection box 7. The foreign objects will be filtered to the outside of the collection box 7 through the inclined filter screen 8, and the water will flow into the drainage pipe 1 through the lower guide pipe 6 through the filter screen 8. When the flow rate is large, the water flows into the top of the drainage pipe 1 through the filter plate 11. The filter plates 11 on both sides of the lower end of the end cover 12 can block foreign objects such as branches and leaves on the outside of the drainage pipe 1, and the end cover 12 can guide the rainwater to both sides, thereby improving the drainage efficiency.

[0020] In addition, the plug 9 is arranged directly below the collection box 7, and a hook 10 is fixedly connected to the lower end of the plug 9. The internal blockage situation can be intuitively seen through the transparent collection box 7. The plug 9 can be directly pulled downwards from the outside with a tool, and then the foreign matter inside can be cleaned, which is convenient for the next use of the collection box 7.

[0021] It should be noted that a small flow of drainage can be discharged through the conduit 6. As the amount of water increases, foreign matter in the water is filtered out through the filter plate 11 and the filter net 8, and the filtered foreign matter will not block the drainage outlet of the drainage pipe 1, thereby avoiding blockage of the drainage pipe 1.

[0022] When in use, rainwater from the roof flows to the drain pipe 1 through the water conduit 2. When the water flow is small, it can be directly discharged into the conduit 6 through the branch channel 4 and directly flow to both sides of the drain pipe 1. As the drainage volume increases, when the flow of the conduit 6 is insufficient to drain the water in time, foreign matter in the water is filtered to the outside through the filter plate 11, and a large water flow is discharged from the upper end of the drain pipe 1. The filtered foreign matter can be collected by the expansion box 5 and the collection box 7, and the foreign matter can be directly taken out from the lower end of the collection box 7, which is convenient for maintenance and cleaning.

[0023] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
