The present disclosure relates to the technical field of architectural decoration and finishing, and in particular, to a rainwater filter and a drainage assembly.
During construction of buildings, gutters are formed at roofs of most buildings to facilitate drainage of rainwater on the roofs. To prevent an existing gutter from being blocked by debris such as fallen leaves and soil, a filter screen may be mounted on the surface of the gutter, allowing rainwater to pass therethrough while leaving the debris accumulated on the surface of the filter screen. When mounting, screws and rivets need to be used for fixing the filter screen to the gutter or the building, causing damage to the original forms of the building and the gutter. Since the filter screen is fixed to the surface of the gutter by screws and rivets, it is hard to dismount and clean the filter screen in case of excessive accumulation of debris or blockage. The debris such as soil that is smaller than the meshes of filter screen mesh is prone to getting into the meshes, and accumulated in the gutter for a long time to form a soil layer which is difficult to remove. As a result, the gutter cannot be protected.
In view of the above, it is necessary to address the problem of drainage of a gutter. An objective of the present disclosure is to provide a rainwater filter and a drainage assembly that can be mounted and dismounted conveniently without being fixed with screws or rivets and are convenient to clean and maintain.
A rainwater filter includes a perforated panel, a filter plate mounted on a top surface of the perforated panel, and at least one elastic support strip mounted on a bottom surface of the perforated panel. One end of the elastic support strip protrudes outwards from the bottom surface of the perforated panel.
In use, the rainwater filter described above is mounted on a drainage gutter which has a recess portion and a clamping groove portion. In use, a bent portion of the elastic support strip abuts against the inner wall of the recess portion, and the top surface of the filter plate abuts against the inner wall of the clamping groove portion. The rainwater filter is limited and clamped within the drainage gutter by the inner wall of the recess portion and the inner wall of the clamping groove portion with the tension of the bent elastic support strip. When dismounting, the filter plate is lifted along the portion close to the inner wall of the recess portion, allowing the elastic support strip to separate from the drainage gutter. With the structure described above, the rainwater filter can be mounted conveniently based on the elastic characteristic of the elastic support strip, without being fixed with screws or rivets. The rainwater filter can be dismounted conveniently in case of excessive accumulation of debris or blockage, is convenient to clean and maintain, and serves to protect the drainage gutter.
In one embodiment, the rainwater filter further includes at least two locking pieces assembled correspondingly with each elastic support strip. The locking pieces are connected to the elastic support strip, the perforated panel and the filter plate. In one embodiment, the locking pieces further include bolts extending through each elastic support strip, the perforated panel and the filter plate in sequence, and nuts mounted at one ends, far away from the elastic support strip, of the bolts, and the nuts abut against the filter plate.
In one embodiment, the locking pieces are rivets disposed to penetrate through the elastic support strip, the perforated panel and the filter plate in sequence.
In one embodiment, the locking pieces are fasteners clamped with the elastic support strip, the perforated panel and the filter plate.
In one embodiment, the perforated panel has a same size with the filter plate.
In one embodiment, the filter plate is made of a porous foam material. In one embodiment, the rainwater filter further includes a stiffener connected to the elastic support strip, and the stiffener and the elastic support strip are disposed to be perpendicular to each other. In one embodiment, a plurality of skidproof stripes arranged at equal intervals are formed on an end, far away from the perforated panel, of the elastic support strip.
In one embodiment, when the elastic support strip is bent, an included angle between the elastic support strip and the perforated panel is 25°-75°. The elastic support strip is capable of providing an auxiliary support force for the perforated panel within the angle described above.
In one embodiment, the perforated panel has a smaller thickness than the filter plate.
The present disclosure provides a drainage assembly including a drainage gutter and a rainwater filter. The drainage gutter has a recess portion and a clamping groove portion. The rainwater filter includes a perforated panel, a filter plate mounted on a top surface of the perforated panel, and at least one elastic support strip mounted on a bottom surface of the perforated panel. One end of the elastic support strip protrudes outwards from the bottom surface of the perforated panel. One end of the filter plate and/or one end of the elastic support strip abut(s) against an inner wall of the clamping groove portion, and the other end of the elastic support strip abuts against an inner wall of the recess portion.

Referring to
Further, the rainwater filter 100 further includes at least two locking pieces 400 assembled correspondingly with each elastic support strip 40. The locking pieces 400 are connected to the elastic support strip 40, the perforated panel 20 and the filter plate 30. The at least two locking pieces 400 form at least two fixed mounting points between the elastic support strip 40, the perforated panel 20 and the filter plate 30, guaranteeing no leftward and rightward sliding and rotation between the elastic support strip 40 and the perforated panel 20 and the filter plate 30 with good stability.
Further, the locking pieces 400 further include bolts 50 extending through each elastic support strip 40, the perforated panel 20 and the filter plate 30 in sequence, and nuts 60 mounted at one ends, far away from the elastic support strip 40, of the bolts 50, and the nuts 60 abut against the filter plate 30. The elastic support strip 40 and the perforated panel 20 and the filter plate 30 may be well fixed by means of the bolts 50 and the nuts 60. A screw of each bolt 50 is sized to be as large as mounting holes of the elastic support strip 40 and the perforated panel 20 and the filter plate 30 or slightly larger than the corresponding mounting holes.
Further, the perforated panel 20 has a same size with the filter plate 30. The perforated panel 20 is made of a material that can be easily cut into a length and has holes formed in the surface thereof, allowing rainwater to flow into the drainage gutter. The filter plate 30 is made of a porous foam filter material (10-30 ppi). The foam filter material plays a role in buffering and may allow rainwater to enter the gutter completely and prevent debris such as fallen leaves and soil. Smaller debris such as fallen leaves and soil can be retained within the porous foam material so that clean rainwater can be obtained for irrigation reuse, saving water resource.
Further, two elastic support strips 40 are used, which are symmetrically located at two ends of the bottom surface of the perforated panel 20, thereby forming two stable and symmetrical elastic force application points. In this embodiment, the perforated panel 20 has a smaller thickness than the filter plate 30.
Referring to
Further, in an embodiment, the locking pieces 400 are rivets (not shown) disposed to penetrate through the elastic support strip 40, the perforated panel 20 and the filter plate 30 in sequence. The elastic support strip 40, the perforated panel 20 and the filter plate 30 may be well fixed together by means of the rivets.
Further, in an embodiment, the locking pieces 400 are fasteners (not shown) clamped with the elastic support strip 40, the perforated panel 20 and the filter plate 30. The elastic support strip 40, the perforated panel 20 and the filter plate 30 may be well clamped together by means of the fasteners.
Further, in another embodiment, the elastic support strip 40, the perforated panel 20 and the filter plate 30 may also be fixed in a local bonding manner provided that the filter area of the perforated panel 20 and the filter plate 30 are guaranteed to be large enough.
Referring to
In an embodiment, one end of the filter plate 30 abuts against the inner wall of the clamping groove portion 320, and the end, far away from the clamping groove portion 320, of the elastic support strip 40 abuts against the inner wall of the recess portion 310.
In use, the rainwater filter 100 described above is mounted on the drainage gutter 300 which has the recess portion 310 and the clamping groove portion 320. In use, a bent portion of the elastic support strip 40 abuts against the inner wall of the recess portion 310, and the top surface of the filter plate 30 abuts against the inner wall of the clamping groove portion 320, forming mutually restraint elastic forces. The rainwater filter is limited and clamped within the drainage gutter 300 by the inner wall of the recess portion 310 and the inner wall of the clamping groove portion 320 with the tension of the bent elastic support strip 40. When dismounting, the filter plate 30 is lifted along the portion close to the inner wall of the recess portion 310, allowing the elastic support strip 40 to separate from the drainage gutter 300. With the structure described above, the rainwater filter may be fixed without screws or rivets, avoiding damage to the original form of the drainage gutter 300 and a building, and can be mounted conveniently based on the elastic characteristic of the elastic support strip 40. The rainwater filter can be dismounted conveniently in case of excessive accumulation of debris or blockage, is convenient to clean and maintain, and serves to protect the drainage gutter 300.
When the elastic support strip 40 serves for supporting and an upward force is applied to the perforated panel 20, the outer side of the perforated panel 20 is completely clamped at the outer side of the drainage gutter 300 to provide the primary support force for bearing. When the elastic support strip 40 is used to provide an auxiliary bearing force, an end of the elastic support strip 40 is bent to prop against the inner sidewall of the drainage gutter 300 to provide an auxiliary support force for bearing.
