Description

Technical Field

[0001] The utility model relates to the technical field of drainage equipment, in particular to a drainage rain bucket. Background Art

[0002] Roof drainage rain gutters are an important part of the building roof drainage system. Rainwater and snow water falling on the roof of the building will form a large amount of water in a short period of time. It is necessary to use the roof drainage system to quickly and systematically transport the roof water to the outside. With the rapid development of the construction industry, the roof surface has aged and cracked due to long-term exposure to wind and sun, and the roof drainage is not smooth, resulting in frequent leakage in weak locations of the roof.

[0003] At present, the traditional practice at the construction site is to mark the center of the rain gutter at the pre-reserved rain outlet and perform elevation processing. According to the marked center position, the rain gutter is placed in the water outlet, and then fixed with fine stone concrete to ensure tight filling. However, the internal drainage of the traditional roof is directly discharged to the outside after the roof surface layer is sloped, and there is a lack of insulation layer drainage measures. Once the roof surface layer is damaged, the water enters the insulation layer along the surface layer and cannot be discharged. Therefore, we propose a drainage rain gutter to solve the above problem. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0005] A rainwater drainage bucket, comprising:

[0006] A floor drain, wherein a flow guide pipe is connected to the middle of the bottom of the floor drain, a top cover is embedded on the upper side of the interior of the floor drain, and water inlet holes are evenly distributed on the surface of the top cover;

[0007] A mesh cover is fixedly arranged at the bottom edge of the floor drain, and a filler is arranged inside the mesh cover;

[0008] The conduit tube is connected to the bottom of the mesh cover. The bottom end of the conduit tube is conical and is provided with a connector for connecting a drain pipe. A limiting ring is fixedly provided inside the conduit tube near the upper port. Leakage holes are evenly distributed on the surface of the limiting ring. The end of the guide tube away from the floor drain slides through the inner circle of the limiting ring and extends into the interior of the conduit tube.

[0009] Furthermore, the inner bottom wall of the floor drain is provided with a Z-shaped plate in a circular array, and the Z-shaped plate is an elastic plate.

[0010] Furthermore, the mesh cover is a galvanized stainless steel cover.

[0011] Furthermore, the filler is volcanic rock.

[0012] Furthermore, the collector tube and the mesh cover are threadedly connected.

[0013] Furthermore, an isolation pad is provided on the top of the limiting ring, and the isolation pad is a PVA sponge pad.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. When the utility model is used, if the surface layer is not damaged, the water on the roof will normally flow to the floor drain and pass through the guide pipe, then flow to the manifold, and finally flow out from the drain pipe because the floor drain is at a lower level. If the surface layer is damaged, the water entering the insulation layer will flow to the mesh cover, then flow to the manifold, and finally flow out from the drain pipe because the mesh cover is at a lower level. In this way, whether the surface layer is not damaged or damaged, it can ensure that the water is discharged smoothly, avoiding the situation where the water cannot be discharged after entering the insulation layer.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0022] The present application provides a drainage rain gutter, which is mainly used to solve the problem that the internal drainage of the traditional roof is directly discharged to the outside after the roof surface layer is sloped, and there is a lack of insulation layer drainage measures. Once the roof surface layer is damaged, the moisture enters the insulation layer along with the surface layer and cannot be discharged. The following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0023] A rainwater drainage bucket, comprising:

[0024] The floor drain 1 has a flow guide pipe 2 in the middle of its bottom, a top cover 3 is embedded on the upper side of the interior of the floor drain 1, and water inlet holes 301 are evenly distributed on the surface of the top cover 3;

[0025] A mesh cover 4 is fixedly arranged at the bottom edge of the floor drain 1, and a filler 5 is arranged inside the mesh cover 4;

[0026] The confluence tube 6 is connected to the bottom of the mesh cover 4. The bottom end of the confluence tube 6 is conical and is provided with a connector 7 for connecting a drain pipe. A limiting ring 8 is fixedly provided near the upper port inside the confluence tube 6. Water leakage holes 801 are evenly distributed on the surface of the limiting ring 8. The end of the guide tube 2 away from the floor drain 1 slides through the inner circle of the limiting ring 8 and extends into the interior of the confluence tube 6.

[0027] The specific implementation process and principle of the drainage rain bucket are as follows:

[0028] During installation and use, the floor drain 1 is located in the surface layer, the mesh cover 4 is located in the insulation layer, and the manifold 6 is located in the concrete layer, wherein a waterproof layer is provided between the surface layer and the insulation layer, and between the insulation layer and the concrete layer. When the surface layer is not damaged, due to the lower terrain at the floor drain 1, the water on the roof will normally flow to the floor drain 1 and pass through the guide pipe 2, then flow to the manifold 6, and finally flow out from the drain pipe. When the surface layer is damaged, due to the lower terrain at the mesh cover 4, the water entering the insulation layer will flow to the mesh cover 4, then flow to the manifold 6, and finally flow out from the drain pipe. This can avoid the situation where the water cannot be discharged after entering the insulation layer.

[0029] like Figure 4 As shown, in some embodiments, the inner bottom wall of the floor drain 1 is provided with a Z-shaped plate 9 in an annular array, and the Z-shaped plate 9 is an elastic plate. More specifically, first, the elastic structure of the Z-shaped plate 9 can provide a buffer when subjected to heavy pressure, reduce the direct impact on the top cover 3, and thus protect the top cover 3 from damage. This design is particularly suitable for bearing loads from above, such as people walking or stepping on during maintenance work, which prolongs the service life of the top cover 3 and the entire drainage system; second, when the top cover 3 needs to be removed for cleaning or maintenance, the operator can first press down one edge of the top cover 3, and use the elastic restoring force of the Z-shaped plate 9 to lift the other side of the top cover 3, so that the top cover 3 can be easily removed. This design simplifies maintenance work, does not require the use of additional tools, and improves work efficiency.

[0030] like Figure 4 As shown, in some embodiments, the mesh cover 4 is a galvanized stainless steel cover. More specifically, the galvanized stainless steel material has excellent corrosion resistance. Since galvanized stainless steel is not easy to rust, no impurities will be generated due to rust during the drainage process. At the same time, the galvanized stainless steel material has higher hardness and strength while maintaining a certain elasticity, so that the mesh cover 4 is both strong and not easy to deform during the installation process, which is convenient for construction operations.

[0031] like Figure 3 As shown, in some embodiments, the filler 5 is volcanic rock. More specifically, volcanic rock, as a natural filter material, has a rich pore structure and can effectively remove impurities such as suspended matter, bacteria, viruses, heavy metal ions, etc. in water. At the same time, volcanic rock has stable chemical properties and a long service life, which can generally reach 3-5 years, and the purchase and maintenance costs are relatively low.

[0032] like Figure 4 As shown, in some embodiments, the junction tube 6 and the mesh cover 4 are threadedly connected. More specifically, the threaded connection is a quick and easy assembly method, so that the junction tube 6 and the mesh cover 4 can be quickly connected at the construction site without complicated tools or excessive technical requirements. When cleaning, maintenance or replacement of parts is required, the threaded connection is easy to disassemble, which makes maintenance work more convenient and efficient. If the mesh cover 4 or the junction tube 6 is damaged, it can be easily removed and replaced with a new part without affecting the structural integrity of the entire drainage system.

[0033] like Figure 3 As shown, in some embodiments, an isolation pad 10 is provided on the top of the limiting ring 8, and the isolation pad 10 is a PVA sponge pad. More specifically, the PVA sponge pad has a porous structure with continuous pores, which can allow water to pass through while blocking larger particles of matter, such as volcanic rock debris, to prevent the leakage hole 801 from being blocked. At the same time, the PVA sponge pad can maintain physical stability during use and will not be easily broken due to water absorption or impact.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
