Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a building drainage structure. Background Technology

[0002] Currently, building drainage structures are used to efficiently collect and discharge domestic sewage and rainwater from buildings, ensuring indoor and outdoor environmental hygiene and normal building functions. They mainly consist of two parts: internal building drainage and external building drainage. In the field of external building drainage, the design of gutter drainage systems, which collect roof rainwater through gutters and discharge it through rainwater hoppers and downpipes, is quite common. However, in existing technologies, the inlets of rainwater hoppers are often blocked by debris such as fallen leaves, branches, building debris, and dust particles, resulting in a significant reduction in drainage efficiency and even potential hazards such as backflow of gutter water and leakage in building structures.

[0003] For existing gutter drainage systems, the common anti-clogging measure is to install metal mesh or plastic grilles at the inlet of the gutter to block debris. However, the debris easily accumulates on the surface of the mesh, and even if it intercepts the debris, it will gradually clog the mesh. Since the existing mesh structure lacks dynamic self-cleaning ability, the accumulated debris needs to be cleaned manually, resulting in a short maintenance cycle and high frequency.

[0004] Therefore, we propose a drainage structure for building structures. Utility Model Content

[0005] This utility model provides a drainage structure for building structures. It features a U-shaped flow channel and a storage bin inside the roof, with an inclined metal mesh between the storage bin and the U-shaped flow channel. The metal mesh intercepts debris on its inclined surface, while gravity allows the accumulated debris to slide down the slope into the storage bin. An infrared sensor on the inner wall of the storage bin continuously monitors the height of the accumulated debris. Furthermore, the bottom of the flow channel uses a conical shape to form a Y-shaped flow path with the drain pipe, accelerating drainage. This solves the problems mentioned in the background art, namely:

[0006] The existing gutter drainage system faces the technical challenge of clogging the rainwater inlet due to debris accumulation, requiring frequent manual cleaning and maintenance.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A building drainage structure includes a roof, the roof having a recess inside, a storage box inside the recess, and U-shaped flow channels on both sides of the storage box located inside the roof.

[0009] A metal mesh is provided between the circulation channel and the storage box, and a drain pipe is provided at the bottom of the circulation channel, which runs through the interior of the house.

[0010] Preferably, the storage bin has grooves at both ends near the flow channel, the metal mesh is located inside the groove of the storage bin, the metal mesh is fixedly connected to the storage bin by a hinge, and the metal mesh has an inclined structure inside the flow channel.

[0011] Preferably, a handle is fixedly connected to the top of the metal mesh, and a bracket is provided on the top of the roof, with the handle movably snapped onto the top of the bracket.

[0012] Preferably, the storage box has elongated square grooves on both sides, and an infrared sensor is installed on the bottom plane of the elongated square groove near the top of the storage box.

[0013] Preferably, the flow channel is U-shaped, the bottom of the flow channel is a conical channel structure, and the bottom of the U-shaped flow channel forms a Y-shaped path with the drain pipe.

[0014] Preferably, the outer wall of the drain pipe is provided with sound insulation cotton, which is a quarter-cylindrical structure, and the inner wall curvature fits the outer wall of the drain pipe; four sound insulation cottons surround the drain pipe to form a cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In a building drainage structure, a groove is precisely chiseled inside the roof to embed a debris box, and a dynamically adjustable metal mesh is connected by a hinge at the junction of the debris box and the U-shaped flow channel, forming a composite structure with both interception and self-cleaning functions. The metal mesh is installed at an inclined angle in the flow channel. When rainwater from the roof carries debris such as fallen leaves and branches through, the mesh first forms a layered interception of the debris: larger debris is directly blocked by the mesh, while small debris passes through the gaps in the mesh with the water flow. The intercepted debris automatically slides down the slope into the debris box under its own gravity, avoiding the formation of a dense accumulation layer on the mesh surface and effectively improving the anti-clogging ability.

[0017] 2. In a building drainage structure, by installing infrared sensors in the long square grooves on both sides of the utility box, the height of the accumulated debris can be sensed in real time. Combined with the handle on the top of the metal mesh and the snap-fit ​​design of the roof support, intelligent monitoring and convenient disassembly and cleaning of the accumulated debris in the utility box can be realized, reducing the frequency and cost of manual maintenance.

[0018] 3. In a building drainage structure, by designing the bottom of the flow channel as a conical structure and forming a Y-shaped flow path with the drain pipe, the principle of fluid dynamics is used to accelerate rainwater discharge. At the same time, the U-shaped flow channel structure can form a water level buffer during heavy rain, preventing backflow of gutter water and improving drainage efficiency and building waterproofing safety.

[0019] 4. In a building drainage structure, by wrapping the outer wall of the drainage pipe with arc-shaped sound insulation cotton, and combining multiple sound insulation cotton to form a cylindrical structure and setting it inside the house, not only can the noise transmission during the drainage process be effectively reduced and the comfort of living inside the building be improved, but it can also keep the drainage pipe warm and reduce the risk of pipe freezing and cracking in severe cold weather.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0029] Please see Figures 1-5 The diagram shows a building drainage structure with a roof 1, a groove inside the roof 1, a storage box 12 inside the groove, and U-shaped flow channels 11 on both sides of the storage box 1 inside the roof 1.

[0030] A metal mesh 13 is provided between the circulation channel 11 and the storage box 12, and a drain pipe 14 is provided at the bottom of the circulation channel 11, which runs through the interior of the house.

[0031] Among them, see Figure 4 and Figure 6 As shown, the storage box 12 has grooves at both ends near the circulation channel 11. A hinge 130 is fixedly connected between the metal mesh 13 and the storage box 12. The metal mesh 13 is movably connected to the groove of the storage box 12 through the hinge 130. When the storage box 12 is embedded in the ceiling groove, the metal mesh 13 is tilted and covers the entrance of the circulation channel 11. When cleaning, pushing the handle 131 can make the metal mesh 13 rotate around the hinge 130 to a vertical state and lock into the groove of the storage box 12.

[0032] When rainwater flows into the U-shaped circulation channel 11 inside the roof 1, the water flows through the metal mesh 13 between the circulation channel 11 and the storage box 12. The metal mesh 13 intercepts fallen leaves, branches and other debris with its sloping structure. The rainwater enters the drain pipe 14 at the bottom of the circulation channel 11 through the gaps in the mesh and flows through the interior of the house and is discharged. Since the metal mesh 13 is connected to the groove of the storage box 12 by the hinge 130 and is set at an angle in the circulation channel 11, the intercepted debris slides down the slope under the action of gravity and accumulates in the storage box 12, avoiding the formation of a blockage layer on the mesh surface. At the same time, the structure of the U-shaped circulation channel 11 can buffer the water flow and work with the drain pipe 14 to drain water from the outside of the building.

[0033] Additionally, see Figure 6 As shown, an infrared sensor is installed on the bottom plane of a long rectangular groove located near the top of the storage box 12. (See reference...) Figure 4 As shown, a handle 131 is fixedly connected to the top of the metal mesh 13, and a bracket 132 is provided on the top of the roof 1. The handle 131 is movably snapped onto the top of the bracket 132.

[0034] When debris from the roof flows into the storage bin 12 and gradually accumulates, the infrared sensors in the long rectangular slots on both sides of the storage bin 12 start to work, emitting infrared signals to the inner wall of the storage bin 12 through infrared transmitters. When the height of the accumulated debris rises to a position parallel to the bottom of the long rectangular slots, it will block the transmission path of the infrared signal, and the receiver will not be able to receive the complete signal, thus generating a change in electrical signal. This signal is transmitted through the circuit to the alarm device inside the building, triggering an early warning and notifying the operator that the accumulated debris in the storage bin 12 has reached the cleaning threshold.

[0035] At this time, the operator can apply force through the handle 131 on the top of the metal mesh 13. Since the handle 131 is movably engaged with the bracket 132 at the top of the roof 1, the handle 131 can disengage along the slot structure at the top of the bracket 132, thereby causing the metal mesh 13 to rotate around the hinge 130, so that the metal mesh 13 is lifted from the inclined position in the flow channel 11, blocking the metal mesh 13 in the grooves at both ends of the miscellaneous box 12, making the metal mesh 13 vertical; when the metal mesh When the grid 13 is vertically engaged in the groove of the storage box 12, the handle 131 and the top of the storage box 12 form a linkage structure; pulling the handle 131 upwards can simultaneously drive the storage box 12 away from the roof groove, thereby cleaning the debris inside the storage box 12; after cleaning, the storage box 12 is placed back into the roof groove, and the handle 131 is re-engaged in the top of the bracket 132, so that the metal grid 13 is reset to the inclined structure in the flow channel 11, continuing to play the role of intercepting debris and guiding it to slide down into the storage box 12.

[0036] See Figure 3 and Figure 4 As shown, the flow channel 11 is a U-shaped channel with a tapered channel structure at the bottom. The bottom of the U-shaped flow channel 11 and the drain pipe 14 form a Y-shaped path.

[0037] When rainwater flows into the U-shaped flow channel 11 from the roof, the U-shaped structure first buffers the water flow, preventing the water from directly impacting the metal mesh 13 during heavy rain and causing debris to accumulate. Then, the water flows down the U-shaped channel and merges into the conical channel at the bottom. The conical structure gradually reduces the cross-section of the channel. According to the principle of fluid dynamics, the water flow speed increases as the cross-section decreases, thereby enhancing the ability to flush away small debris on the surface of the metal mesh 13. Finally, the conical channel and the drain pipe 14 form a Y-shaped flow path. This path design creates a diversion effect when the water flows converge, accelerating the main drainage speed.

[0038] See Figure 7 As shown, the outer wall of the drain pipe 14 is provided with sound insulation cotton 140. The sound insulation cotton 140 is a quarter-cylindrical structure, and its inner wall curvature fits the outer wall of the drain pipe 14. Four sound insulation cotton 140 surround the drain pipe 14 to form a cylinder.

[0039] Since the drain pipe 14 is located inside the house, water flow noise is generated when water flows through it. Multiple arc-shaped sound insulation cotton 140s are spliced ​​together to form a cylindrical structure that fits tightly against the outer wall of the pipe. The porous fiber material inside absorbs the sound wave energy generated by the water flow hitting the pipe wall. The sound energy is converted into heat energy and dissipated through the damping effect of the sound insulation cotton 140. At the same time, the cylindrical wrapping structure forms a sealed sound insulation layer, blocking the transmission of noise into the house. In addition, since the sound insulation cotton 140 is placed inside the house, its thermal insulation material can also reduce the heat exchange between the pipe and the outside in cold weather, which can keep the drain pipe 14 warm and reduce the risk of freezing and cracking caused by the expansion of water inside the pipe. This achieves the dual functions of sound insulation and thermal insulation.

[0040] In addition, it should be noted that the specific dimensions of the storage box 12, the U-shaped flow channel 11, and the drain pipe 14 in this utility model can be adjusted according to the actual working conditions such as the building roof area and drainage requirements, as shown in the figure ( Figures 1-7 The size proportions of the components shown are for structural principle illustration only and do not represent actual dimensions. Parameters such as the embedment depth of the storage box 12, the cross-sectional width of the flow channel 11, and the diameter of the drain pipe 14 need to be calculated according to building drainage specifications (e.g., determining the drain pipe diameter based on the roof catchment area). However, to clearly show the assembly relationship and linkage logic of each component, detailed dimensional proportions are not provided in the illustration. In actual applications, adaptive designs can be made according to project requirements.
