Description

Technical Field

[0001] This utility model belongs to the field of rainwater harvesting technology, and in particular relates to a rainwater harvesting system for wood-plastic composite houses. Background Technology

[0002] The main purpose of a building's rainwater system is to collect rainwater to prevent the ground around the building from being washed away by rainwater from the roof over a long period of time, which could damage the ground and cause damage to the building's foundation.

[0003] Wood-plastic composite houses are mostly located in courtyards and are generally not very tall. Therefore, the rainwater system needs to be designed to filter fallen leaves and other debris. Ordinary rainwater harvesting systems cannot filter and collect leaves and debris, and directly collecting rainwater will increase the risk of blockage in the subsequent rainwater collection pipes. Utility Model Content

[0004] This utility model provides a rainwater harvesting system for wood-plastic composite houses, aiming to solve the problem that current rainwater harvesting systems cannot filter and collect leaves and other debris in the environment of wood-plastic composite houses, which increases the risk of blockage in the subsequent rainwater harvesting pipes.

[0006] The roof beam frame and the roof tiles assembled on the roof beam frame, wherein the roof beam frame is provided with a rainwater gutter beam at the end away from the ridge;

[0007] The collection unit includes a rainwater trough, a rainwater pipe, and a drainage box connected to the rainwater pipe; the rainwater trough is located between the end of the roof tile away from the ridge and the rainwater trough beam, and the rainwater trough is connected to the drainage box through the rainwater pipe;

[0008] The drainage tank includes a tank body and a filter element disposed inside the tank body. The filter element includes a vertical partition plate set perpendicular to the ground and a filter plate connected perpendicular to the vertical partition plate. One end of the vertical partition plate is connected to the end face of the tank body away from the ground, and the other end of the vertical partition plate is connected to the end face of the tank body near the ground as a water flow channel. Rainwater entering the tank body through the rainwater pipe passes through the water flow channel, bypasses the vertical partition plate, and then flows in the opposite direction through the filter plate before leaving the tank body.

[0009] Preferably, the end face of the box away from the ground is provided with a cover plate, the cover plate is provided with a guide pipe connected to the rainwater pipe, the side wall of the box is provided with a drain outlet, and the drain outlet is connected to the filtration area separated by the vertical partition plate and the filter plate.

[0010] Preferably, the filter plate is arranged parallel to the ground, with one end of the filter plate in contact with the side wall of the housing and the other end fixedly connected to the connection between the upper partition and the lower grid plate.

[0011] Preferably, the filter plate includes a filter plate and filter holes disposed on the filter plate. The number of filter holes is several groups, which are arranged on the filter plate in an array distribution. An isolation cover with sieve holes is provided on the side of the filter holes near the ground.

[0012] Preferably, the isolation cover is an inverted quadrangular pyramid structure.

[0013] Preferably, the vertical partition plate includes an upper partition plate and a lower grid plate, the upper partition plate is connected to the cover plate, the lower grid plate is spaced apart from the end face of the box body near the ground, and the water flow channel is located between the lower grid plate and the box body.

[0016] Preferably, the diameter of the rainwater pipe is smaller than that of the guide pipe, and the rainwater pipe is inserted into the guide pipe.

[0017] Compared with the prior art, the embodiments of this application have the following main advantages:

[0018] The rainwater harvesting system for wood-plastic composite houses provided by this utility model utilizes vertical partitions and filter plates to create a filtration zone inside the housing. This allows rainwater to flow from the water channel to the bottom of the filtration zone. Debris such as leaves that easily clog pipes in the rainwater will not easily settle at the water channel due to their density and will not easily reach the bottom of the filtration zone. This prevents some suspended debris from easily passing through the water channel to the bottom of the filtration zone. The principle of deflection design reduces the accumulation of debris near the filter screen, reduces the filtration difficulty, and avoids drainage blockage. Through reasonable structural design, debris is trapped in the drainage tank, ensuring smooth drainage while reducing the risk of subsequent pipe blockage. Attached Figure Description

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0030] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] This utility model embodiment provides a rainwater harvesting system for wood-plastic composite houses, such as... Figures 1-7As shown, the rainwater harvesting system for a wood-plastic composite house includes:

[0032] The roof beam frame 110 and the tile surface 120 assembled on the roof beam frame 110, wherein the roof beam frame 110 is provided with a rainwater gutter beam 130 at the end away from the ridge.

[0033] The collection unit 200 includes a rainwater trough 210, a rainwater pipe 220, and a drainage box 230 connected to the rainwater pipe 220; the rainwater trough 210 is located between the end of the roof tile 120 away from the ridge and the rainwater trough beam 130, and the rainwater trough 210 is connected to the drainage box 230 through the rainwater pipe 220.

[0034] The drainage tank 230 includes a tank body 233 and a filter element 232 disposed inside the tank body 233. The filter element 232 includes a vertically arranged vertical partition plate 2322 and a filter plate 2321 connected to the vertical partition plate 2322. One end of the vertical partition plate 2322 is connected to the end face of the tank body 233 away from the ground, and the other end of the vertical partition plate 2322 is connected to the end face of the tank body 233 near the ground to form a water flow channel.

[0035] The end face of the box 233 away from the ground is provided with a cover plate 231. The cover plate 231 is provided with a guide pipe for accommodating the end of the rainwater pipe 220. The side wall of the box 233 is provided with a drain outlet 234. The drain outlet 234 is connected to the filtration area separated by the vertical partition plate 2322 and the filter plate 2321. The rainwater entering the box 233 through the rainwater pipe 220 enters one side of the vertical partition plate 2322 along the direction of gravity. In the water flow channel, the rainwater bypasses the vertical partition plate 2322 and reaches the bottom of the filter plate 2321. The rainwater will pass through the filter plate 2321 and leave the box 233 from the drain outlet 234 provided on the side wall of the box 233. Generally, the drain outlet 234 faces the nearby sewer opening.

[0036] In this embodiment, the vertical partition plate 2322 includes an upper partition plate and a lower grid plate. The upper partition plate is connected to the cover plate 231. The lower grid plate is spaced apart from the end face of the box 233 near the ground. The water flow channel is located between the lower grid plate and the box 233. Here, the upper partition plate separates the filtration area from the inside of the box 233, allowing rainwater to reach the bottom of the filtration area from the lower grid plate and the water flow channel. Since debris such as leaves that easily clog pipes in rainwater are not easy to settle at the water flow channel due to their density, they are not easy to reach the bottom of the filtration area, thereby reducing the pressure on the filter plate 2321. The function of the lower grid plate is to further increase the filtration depth and prevent some suspended debris from easily reaching the bottom of the filtration area through the water flow channel. The principle of the folding design reduces the accumulation of debris near the filter screen, reduces the filtration difficulty, and avoids drainage blockage.

[0037] In a preferred embodiment of this example, the rainwater trough 210 includes a trough body 211, a plug 212, and a rainwater outlet 213. The plug 212 is disposed at both ends of the trough body 211, and the rainwater outlet 213 is disposed on the end face of the trough body 211 near the ground. The rainwater outlet 213 is connected to a rainwater pipe 220. An extension plate 214 is provided at the end of the trough body 211 away from the roof ridge, and the extension plate 214 is connected to the rainwater trough beam 130.

[0038] The rainwater gutter beam 130 is spaced apart from the tile surface 120. The rainwater trough 210 mounted on the rainwater gutter beam 130 fills the gap between the rainwater gutter beam 130 and the tile surface 120. Rainwater on the tile surface 120 will reach the rainwater trough 210 and reach the drainage box 230 along the rainwater pipe 220.

[0039] In a preferred embodiment of this invention, the filter plate 2321 is arranged parallel to the ground. One end of the filter plate 2321 is in contact with the side wall of the housing 233, and the other end is fixedly connected to the connection between the upper partition and the lower grid plate.

[0040] The filter plate 2321 includes a filter plate and filter holes 23211 disposed on the filter plate. The number of filter holes 23211 is several groups, which are arranged on the filter plate in an array distribution. An isolation cover 23212 with sieve holes is provided on the side of the filter hole 23211 near the ground.

[0041] In this embodiment, the isolation cover 23212 is an inverted quadrangular pyramid structure. The quadrangular pyramid structure is used to form an irregular structure to prevent leaves and other debris from directly adhering to the filter holes 23211 of the planar structure and affecting the drainage effect.

[0042] In a preferred embodiment of this invention, the diameter of the rainwater pipe 220 is smaller than that of the guide pipe, and the rainwater pipe 220 is inserted into the guide pipe.

[0043] In this application, the cover plate 231 can be assembled with the box body 233 by a snap-fit ​​method, and the vertical partition plate 2322 is fixedly connected to the cover plate 231. Since the diameter of the guide pipe is larger than that of the rainwater pipe 220, when the cover plate 231 is lifted, the box body 233 can be separated from the cover plate 231 and the filter element 232. Then, the box body 233 can be taken out from under the rainwater pipe 220. After removing the box body 233, the cover plate 231 and the filter element 232 can be removed from the rainwater pipe 220. This design facilitates the cleaning of the box body 233 and the filter element 232. Generally, the drainage box 230 needs to be cleaned regularly to reduce the accumulation of debris inside the drainage box 230 and reduce its impact on drainage performance. In addition to the disassembly method in this application, the cover plate 231, the filter element 232 and the box body 233 can also be disassembled in other ways.
