Description

Technical Field

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

[0002] Water supply and drainage systems refer to the systems composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater. Because the water bodies they collect are generally quite complex, impurities inevitably accumulate and adhere to the inside of the pipes over time, which can even lead to pipe blockage and seriously affect the normal use of the water supply and drainage system.

[0003] To address the above issues, existing technologies typically involve installing filters at the drain pipes to pre-treat the collected water and filter out impurities, thereby effectively preventing blockages in subsequent pipes. However, as usage time increases, to ensure the filtration effect of the filters, they need to be disassembled and cleaned regularly, or replaced periodically. Each disassembly, cleaning, or replacement requires a large amount of manual labor and necessitates measures to ensure airtightness, resulting in extremely low efficiency.

[0004] Therefore, this application is hereby submitted. Summary of the Invention

[0005] The purpose of this utility model is to provide a building water supply and drainage system that solves the problem of low efficiency in cleaning filter components of water supply and drainage systems.

[0007] In another preferred embodiment, the sidewall of the outlet end of the drain pipe and the sidewall of the inlet end of the water collection pipe are symmetrically provided with ear plates; the filter plate is in the shape of a disc, and the sidewall of the filter plate is provided with ear blocks, which are sandwiched between a pair of ear plates and are hinged to the two ear plates; the end face of the slide cylinder facing the drain pipe is provided with an ear groove along the axial direction, and the ear groove matches the ear plate and the ear block.

[0008] In another preferred embodiment, the ear plate and the ear block are hinged by a sliding rod shaft, and the sliding rod is arranged parallel to the drain pipe; the drain pipe is slidably connected to the sliding rod through the ear plate, so that the drain pipe can be close to or away from the water collection pipe.

[0009] In another preferred embodiment, a sealing ring is coaxially protruded from the end face of the filter plate facing the outlet end of the drain pipe. The sealing ring is an elastic ring, and the outer diameter of the sealing ring is slightly larger than the inner diameter of the drain pipe. The end face of the sealing ring is set as a conical surface.

[0010] In another preferred embodiment, the end of the slide bar is provided with a limiting piece, and when the ear plate abuts against the limiting piece, the width of the gap is greater than the total thickness of the filter plate and the sealing ring.

[0011] In another preferred embodiment, a retaining ring is coaxially protruded from the outer wall of the outlet end of the drain pipe; a plurality of claws are axially protruded from the end face of the slide cylinder facing the drain pipe. When the claws engage with the retaining ring, the filter plate is tightly clamped in the gap, and the sealing ring is embedded in the outlet end of the drain pipe. The outlet end of the drain pipe, the inlet end of the water collection pipe, and the filter plate located in the gap are all located inside the slide cylinder.

[0012] In another preferred embodiment, at least two filter plates are connected in a ring around the ear block.

[0013] In another preferred embodiment, the spring is coaxially fitted outside the water collection pipe, with one end of the spring connected to the end of the slide cylinder away from the drain pipe, and the other end connected to the outer wall of the water collection pipe.

[0014] In another preferred embodiment, the system includes two sets of drain pipes and a water collection pipe, with each drain pipe equipped with a water valve.

[0015] In another preferred embodiment, the inlet ends of the two drain pipes are respectively slidably connected to a manifold, and the inlet ends of the two manifolds are connected to a main pipe via a tee.

By setting up a drain pipe and a collection pipe, which are coaxially spaced to form a gap between them, a filter plate is installed. This filter plate is eccentrically hinged to either the drain pipe or the collection pipe, allowing it to screw into or out of the gap. Screwing into the gap seals it and connects the drain pipe and collection pipe through the filter plate; screwing out facilitates cleaning. A sliding cylinder is coaxially mounted with the collection pipe and connected to it via a spring. The spring force pushes and supports the sliding cylinder, further sealing the connection between the drain pipe, collection pipe, and filter plate from the outside and limiting the rotation of the filter plate to prevent it from coming off. When cleaning the filter plate is needed, simply apply axial force to the sliding cylinder to compress the spring, exposing the filter plate, which can then be screwed out for cleaning. Through the cooperation of these features, this building water supply and drainage system effectively solves the problem of low efficiency in cleaning filter components in water supply and drainage systems.

Detailed Implementation

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane". Example 1

[0022] Please refer to Figures 1 to 5 As shown, this embodiment provides a building water supply and drainage system, including a drain pipe 10, the inlet end of which is connected to the external environment; a second system includes a water collection pipe 11, which is coaxially arranged with the drain pipe 10, the inlet end of which is connected to the outlet end of the drain pipe 10 with a pre-set gap, and the outlet end of the water collection pipe 11 is connected to a water storage tank 12, which is equipped with multiple faucets 121; and a third system includes a filter plate 20, which is connected to the drain pipe 10 or the water collection pipe. 11. An eccentric shaft hinge is provided so that the filter plate 20 can be screwed into or out of the gap; the fourth part includes a slide cylinder 30, which is coaxially and slidably fitted with the water collection pipe 11. The inner diameter of the slide cylinder 30 matches the outer diameter of the drain pipe 10 and the water collection pipe 11. The slide cylinder 30 is connected to the water collection pipe 11 by a spring 31. When the spring 31 is in its natural state, the outlet end of the drain pipe 10, the inlet end of the water collection pipe 11, and the filter plate 20 located in the gap are all located inside the slide cylinder 30.

[0023] The building water supply and drainage system disclosed in this embodiment uses a drain pipe 10 and a water collection pipe 11, which are coaxially spaced to form a gap between them. A filter plate 20 is then installed, with an eccentric hinge to either the drain pipe 10 or the water collection pipe 11, allowing it to be screwed into or out of the gap. Screwing into the gap seals it and connects the drain pipe 10 and the water collection pipe 11 through the filter plate 20; screwing out facilitates cleaning. A sliding cylinder 30 is installed, which is coaxially slidably fitted with the water collection pipe 11 and connected to it by a spring 31. The connection utilizes the elastic force of spring 31 to push and support the slide cylinder 30, further sealing the connection between the drain pipe 10, the water collection pipe 11, and the filter plate 20 from the outside, and limiting the rotation of the filter plate 20 to prevent it from coming off. When it is necessary to clean the filter plate 20, simply apply an axial force to the slide cylinder 30 to compress the spring 31, exposing the filter plate 20, and then unscrew it for cleaning. Through the cooperation of the above features, this building water supply and drainage system can effectively solve the problem of low efficiency in cleaning filter components in water supply and drainage systems.

[0024] To provide a specific explanation of the hinge structure of the filter plate 20, the sidewall of the outlet end of the drain pipe 10 and the sidewall of the inlet end of the water collection pipe 11 are symmetrically provided with ear plates 13; the filter plate 20 is in the shape of a circular plate, and the sidewall of the filter plate 20 is provided with ear blocks 21, which are sandwiched between a pair of ear plates 13 and are hinged to the two ear plates 13; the end face of the slide cylinder 30 facing the drain pipe 10 has an axially formed ear groove, which matches the ear plate 13 and the ear block 21.

[0025] By setting ear plate 13 and ear block 21, the filter plate 20 is hinged by the two. By opening ear groove, the slide cylinder 30 can avoid ear plate 13 and ear block 21 to close the gap.

[0026] To facilitate inserting the filter plate 20 into the gap, the ear plate 13 and the ear block 21 are hinged by a sliding rod 14, which is arranged parallel to the drain pipe 10. The drain pipe 10 is slidably connected to the sliding rod 14 through the ear plate 13, so that the drain pipe 10 can be close to or away from the water collection pipe 11.

[0027] With the above setup, before inserting the filter plate 20, the drain pipe 10 and the water collection pipe 11 are moved away to increase the width of the gap. Then the filter plate 20 is screwed in, and then the width of the gap is reduced until it is sealed.

[0028] To further improve the sealing performance of the filter plate 20, a sealing ring 22 is coaxially protruded on the end face of the filter plate 20 facing the outlet end of the drain pipe 10. The sealing ring 22 is an elastic ring, and the outer diameter of the sealing ring 22 is slightly larger than the inner diameter of the drain pipe 10. The end face of the sealing ring 22 is set as a conical surface.

[0029] With the above settings, and combined with the design that the drain pipe 10 can be kept away from the water collection pipe 11, the filter plate 20 and the drain pipe 10 are connected by the sealing ring 22, which further improves the sealing performance between the two to avoid water leakage during the filtration process.

[0030] The end of the slide bar 14 is provided with a limiting piece 141. When the ear plate 13 abuts against the limiting piece 141, the width of the gap is greater than the total thickness of the filter plate 20 and the sealing ring 22.

[0031] Since the drain pipe 10 can slide away from the water collection pipe 11, and the slide cylinder 30 can also slide, in order to achieve final positioning and limiting, a retaining ring 15 is coaxially protruded on the outer wall of the outlet end of the drain pipe 10; a plurality of claws 32 are axially protruded on the end face of the slide cylinder 30 facing the drain pipe 10. When the claws 32 are engaged with the retaining ring 15, the filter plate 20 is tightly clamped in the gap, and the sealing ring 22 is embedded in the outlet end of the drain pipe 10. The outlet end of the drain pipe 10, the inlet end of the water collection pipe 11, and the filter plate 20 located in the gap are all located in the slide cylinder 30.

[0032] With the above settings, after cleaning the filter plate 20, the claw 32 engages with the retaining ring 15, thereby restricting the axial movement of the drain pipe 10 and the slide cylinder 30, and indirectly ensuring the sealing performance of the connection between the drain pipe 10, the filter plate 20 and the water collection pipe 11.

[0033] To further improve the cleaning speed, at least two filter plates 20 are connected in a ring around the ear block 21.

[0034] With the above settings, the filter plate 20 is arranged in the shape of a revolving wheel. Each time cleaning is required, the wheel can be rotated with the lug 21 as the center to screw the adjacent filter plate 20 into the gap. Then, the claw 32 is engaged with the retaining ring 15, and finally the screwed-out filter plate 20 is cleaned.

[0035] To optimize the placement of the spring 31, the spring 31 is coaxially fitted onto the outside of the water collection pipe 11. One end of the spring 31 is connected to the end of the slide cylinder 30 away from the drain pipe 10, and the other end is connected to the outer wall of the water collection pipe 11. Example 2

[0036] Please refer to Example 1. Figure 6As shown, this embodiment provides a building water supply and drainage system, which differs from Embodiment 1 only in that: To ensure that the pipeline remains connected when cleaning the filter plate 20, it includes two sets of drain pipes 10 and water collection pipes 11, and both drain pipes 10 are equipped with water valves 16.

[0037] With the above setup, two sets of pipes are used alternately. When it is necessary to clean the filter plate 20 of one pipe, simply close the water valve 16 on it and open the water valve 16 on the other pipe.

[0038] To further optimize the pipeline structure, a manifold 17 is slidably inserted into the inlet end of each of the two drainage pipes 10, and the inlet ends of the two manifolds 17 are connected to a main pipe 18 via a tee.

[0039] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
