Description

Technical Field

[0001] This utility model relates to the field of building drainage technology, and in particular to a building water supply and drainage pipe. Background Technology

[0002] Drainage pipes are an indispensable infrastructure in municipal engineering and construction. They consist of the main pipe body and connecting fittings. Their core function is to transport and discharge water, covering different types of water bodies such as domestic sewage, rainwater, and industrial wastewater. Building water supply and drainage pipes are specialized drainage systems designed for individual buildings or building complexes. They are an important part of the water and electricity facilities inside buildings. Some building water supply and drainage pipes integrate filtration and anti-clogging functions to further improve water quality safety and pipeline operation stability.

[0003] A search revealed Chinese patent publication number CN222992474U, which discloses a building water supply and drainage pipe, including a first pipe and a second pipe connected by a connecting bend. The connecting bend contains a filtration mechanism and a cleaning mechanism arranged sequentially downwards. The filtration mechanism includes a secondary filter housing, a guide pipe, a primary filter housing, and a conical filter cylinder. The cleaning mechanism includes a rotating shaft, a transmission shaft, a set of inclined rods, a set of scrapers, and several spiral blades. The beneficial effects of this invention are that the conical filter cylinder first filters impurities in the water within the connecting bend, and then performs secondary filtration in conjunction with the secondary filter housing. Manual rotation of the handle drives a set of scrapers to clean impurities from the surface of the conical filter cylinder. Simultaneously, the rotating shaft drives several spiral blades to rotate, preventing blockage at the bottom of the connecting bend. Users can periodically clean the impurities collected in the secondary filter housing through the cleaning port, making it convenient to use. However, in actual use, when internal filter impurities accumulate and need cleaning, the pipe needs to be disassembled, making cleaning somewhat cumbersome. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a building water supply and drainage pipe, which aims to improve the problem that the existing technology requires disassembling the pipe when cleaning debris, making the cleaning process cumbersome.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a building water supply and drainage pipe, including a straight pipe, a bend at the bottom of the straight pipe, a filter mechanism inside the straight pipe, and a connecting mechanism at the bottom of the outer wall of the straight pipe, the connecting mechanism being used to connect the straight pipe and the bend. The filtration mechanism includes two upright plates, with their opposite sides fixedly connected to the front and rear sides of the inside of a straight tube. Each of the two upright plates has a sliding groove on an adjacent side, and a sliding plate is slidably connected inside the sliding groove. The bottom of each of the two sliding plates is fixedly connected to the same mounting ring on an adjacent side. The mounting ring has an mounting groove on its inner side and an opening groove on its right side, with a filter disc slidably connected inside the opening groove. Pulling plates are fixedly connected to the top of each of the two sliding plates on adjacent sides. A sealing assembly is provided at the bottom of the mounting ring, and a fixing assembly is provided on the top right side of the mounting ring. A top cover assembly is provided at the top of the straight tube.

[0006] Through the above technical solution: In the building's water supply and drainage pipeline, the straight pipe serves as the core water conveyance channel, providing a stable flow path for water. The bend at its bottom can flexibly change the direction of water flow, adapting to the complex pipeline layout requirements within the building. The filtration mechanism inside the straight pipe is responsible for intercepting impurities in the water flow, ensuring water quality cleanliness. The connecting mechanism at the bottom of the outer wall of the straight pipe can firmly connect the straight pipe and the bend, preventing water leakage at the connection and ensuring smooth water delivery throughout the pipeline. The two vertical plates in the filtration mechanism are fixed to the front and rear sides of the straight pipe from opposite sides, providing stable support for the entire filtration structure. The sliding groove opened on the adjacent side of the vertical plate can guide the sliding plate to slide up and down, providing a moving track for the installation and maintenance of the filter components. The sliding plate can carry... The mounting rings, fixed at the bottom of adjacent sides, move synchronously, facilitating position adjustment. The mounting groove inside the ring precisely accommodates and positions the filter disc, preventing it from wobbling. The opening on its right side allows for quick insertion and removal of the filter disc, simplifying component replacement. The filter disc directly intercepts impurities in the water flow, achieving water filtration. A pull plate fixed at the top of the adjacent side of the sliding plate provides a leverage point for operators to easily adjust the mounting ring's position. The sealing component at the bottom of the mounting ring enhances the filter mechanism's sealing, preventing unfiltered water from flowing through gaps. The fixing component on the top right of the mounting ring secures the filter disc, preventing displacement due to water flow impact.

Connecting blocks fixedly connected to both the front and rear sides of connecting ring one serve as mounting carriers for fixing bolts, providing support points for subsequent fixing operations. Simultaneously, through cooperation with fixing block two, they form a connecting bridge between connecting ring one and connecting ring two. Connecting ring two, fixedly connected to the top of the outer wall of the bend, is a key component for connecting the bend. It corresponds and cooperates with connecting ring one to form an overall framework for the connection between the straight and bend pipes, ensuring the stability of the connection. The connecting ring two, fixedly connected to both the front and rear sides... Fixed block two can precisely align with the connecting block. The fixed groove two on its right side can be adapted to the fixed bolt, providing space for the fixed bolt to be screwed in. The connecting block and fixed block two are tightly fixed through threaded connection. The fixed bolts that are rotatably connected to the right side of both connecting blocks can be rotated and screwed into the fixed groove two to firmly lock the connecting block and fixed block two together. This makes connecting ring one and connecting ring two stably connected, and finally achieves a reliable connection between straight pipe and curved pipe, preventing loosening and leakage at the connection. The guide component at the bottom of connecting ring one can play a precise positioning role during installation, helping connecting ring one and connecting ring two to be quickly aligned, avoiding installation deviation, improving installation efficiency, and ensuring the smooth progress of subsequent fixing operations.

When under maintenance, it can be slid open to operate the filter components, thus balancing protection and convenience.

[0015] As a further description of the above technical solution: The guiding assembly includes a guide ring, the top of which is fixedly connected to the bottom of the first connecting ring, and the top of the second connecting ring has a guide groove.

[0016] The above technical solution involves fixing the top of the guide ring to the bottom of the first connecting ring.

[0017] As a further description of the above technical solution: The right side of the mounting groove is connected to the left side of the opening groove, and the outer wall of the filter disc matches the size of the mounting groove.

[0018] The above technical solution connects the right side of the mounting groove to the left side of the opening groove, and the outer wall of the filter disc matches the size of the mounting groove. This facilitates the filter disc to slide quickly from the opening groove into the mounting groove, while ensuring a tight fit between the filter disc and the mounting groove.

[0019] As a further description of the above technical solution: The first fixing block is internally slidably connected to the first fixing groove, and the left side of the first fixing block is attached to the right side of the filter disc.

[0020] Through the above technical solution: the fixing block 1 is slidably connected to the fixing groove 1, and the left side of the fixing block 1 is attached to the right side of the filter disc. By sliding the fixing block 1, its position in the fixing groove 1 can be adjusted, thereby achieving tight positioning of the filter disc by attaching it to the filter disc.

[0029] Working Principle: During operation, the water supply and drainage pipes of this building first enter from the top of the straight pipe 1. Before reaching the bend 4, the water needs to pass through the filter mechanism 2 to filter impurities. At the same time, the connecting mechanism 3 ensures a stable connection between the straight pipe 1 and the bend 4, ensuring the normal water supply and filtration functions of the entire pipeline. In the filter mechanism 2, two vertical plates 201 are fixed to the front and rear sides of the straight pipe 1 on opposite sides. The sliding groove 202 on their adjacent sides provides a sliding track for the sliding plate 203. When it is necessary to install or replace the filter disc 207, the pulling plate 208 fixed at the top of the adjacent side of the two sliding plates 203 can be pulled to drive the sliding plate 203 to slide up and down along the sliding groove 202. This, in turn, drives the same mounting ring 204 fixed at the bottom of the adjacent side of the sliding plate 203 to move synchronously. The mounting groove 205 on the inner side of the mounting ring 204 is used to accommodate and position the filter disc 207, while the opening groove on the right side... 206 facilitates the insertion and removal of the filter disc 207. When the mounting ring 204 moves down to the working position, the sealing ring 2093 fixed at its bottom will be embedded in the sealing groove 2092 opened at the top of the bottom ring 2091. The bottom ring 2091 is fixed inside the straight pipe 1 through the outer wall. The two together form a sealing assembly 209 to prevent unfiltered water from flowing through the gap between the mounting ring 204 and the bottom ring 2091, ensuring the filtration effect. At the same time, in the fixing assembly 210 set on the top right side of the mounting ring 204, the bottom of the fixing block 2101 is connected to the top right side of the mounting ring 204. Combined with the fixing groove 2102 opened on the top right side of the mounting ring 204, the filter disc 207 can be fixed to prevent the filter disc 207 from shifting due to water flow impact. The top cover 2112 at the top of the straight pipe 1 places the top of the arc-shaped block 2111, which can close the pipe opening when the pipe is not under maintenance to prevent external impurities from entering. Furthermore, the guide component 307 at the bottom of the connecting ring 1 301 plays a precise positioning role: the top of the guide ring 3071 is fixed to the bottom of the connecting ring 1 301. During installation, it needs to be embedded into the guide groove 3072 opened at the top of the connecting ring 2 303. Through the cooperation of the guide ring 3071 and the guide groove 3072, the positions of the connecting block 302 and the fixing block 2 304 are quickly aligned to avoid installation deviation. After positioning, the fixing bolt 306 rotatably connected on the right side of the connecting block 302 is rotated and screwed into the fixing groove 2 305 opened on the right side of the fixing block 2 304. Through the threaded connection between the fixing bolt 306 and the fixing groove 2 305, the connecting block 302 and the fixing block 2 304 are tightly fixed, thereby making the connecting ring 1 301 and the connecting ring 2 303 firmly connected. Finally, a stable connection between the straight pipe 1 and the bend 4 is achieved, ensuring that the water flows smoothly from the straight pipe 1 into the bend 4 and preventing water leakage at the connection.
