Description

Technical Field

[0001] This invention relates to the field of rainwater harvesting technology, specifically to a large flexible water cellar and its installation method. Background Technology

[0002] A document with publication number CN113863428A discloses a method for fixing a large flexible water cellar. The method involves using plastic-coated steel wire ropes that pass through a central ring extending from the lower part of a filter screen base via circular holes. All the filter screens are connected by steel wire ropes in a horizontal, vertical, or crisscrossing mesh pattern. The ends of the steel wire ropes pass through the high points of the side of the water cellar below the rainwater collection surface and are reinforced to the ground, forming a steel wire rope support net with the filter screens as fixing points to support the rainwater collection surface. Supporting column pipes or filter tubes are inserted into the central ring of the filter screen base. Holes are made in the supporting column pipes, matching the holes in the filter screen base, and then steel wire ropes are threaded through the supporting column pipes or filter tubes, forming a mesh with the supporting column pipes or filter tubes.

[0003] Existing flexible water cisterns typically have multiple filter holes on the rainwater collection surface. This facilitates rainwater collection and also filters impurities. To prevent rainwater accumulation on the collection surface and damage to the flexible water cistern installation, anchor bolts are usually installed on the sides of the cistern to stabilize it and improve its stability. The above-mentioned solution further enhances its stability by installing filter pipes at the filter holes on the rainwater collection surface for support, thus distributing the pressure of rainwater accumulation. However, in actual installation and construction, the installation and subsequent removal of these filter pipes are quite cumbersome. Furthermore, their central location on the collection surface makes maintenance difficult. Further improvements and optimizations are needed.

The fastening slots 503 and the locking plates 45 have the same number of sets, and one end of the locking plate 45 is compatible for locking with the fastening slots 503.

[0027] A collection cylinder assembly is provided in the support sleeve 501. The collection cylinder assembly includes a collection cylinder body 601, a diversion disc cover 602, a support rod 603, a connecting plate 604, mounting screws 605, a cover plate 606, a positioning screw 607, a second handle 608, an auxiliary lifting ring 609, and a filter auxiliary assembly. The collection cylinder body 601 is placed in the support sleeve 501. A diversion disc cover 602 is fixedly installed on one side of the collection cylinder body 601. Support rods 603 are fixedly installed at equal intervals on the diversion disc cover 602. The other end of the support rod 603 is fixedly installed on the connecting plate 604. The connecting plate 604 is fixedly connected to the cover plate 606 by mounting screws 605. An auxiliary lifting ring 609 is fixedly installed on the cover plate 606.

A second handle 608 is fixedly installed on one end of the positioning screw 607.

[0028] Here, filter auxiliary components are equidistantly arranged on the side of the collection cylinder 601. The filter auxiliary components include auxiliary channels 701, conical tube heads 702, and filter mesh 703. The auxiliary channels 701 are equidistantly arranged on the side of the collection cylinder 601 and penetrate through the side wall of the collection cylinder 601. A conical tube head 702 is fixedly arranged at the outer slot of the auxiliary channels 701, and a filter mesh 703 is provided on the conical tube head 702.

[0029] In this embodiment, a collection auxiliary mechanism is set at the corner of the water cellar body 1 to facilitate subsequent installation, disassembly, and maintenance by staff. Rainwater is collected on the rain collection surface 2 of the water cellar. Some rainwater enters the water cellar through the filter mesh 21, while some rainwater enters through the diversion channel 504 on the support sleeve 501. The entering rainwater passes through the diversion disc cover 602 and enters the collection cylinder 601, where it is filtered. The filtered rainwater then flows through the auxiliary channel 701 and the filter mesh 703 on the conical pipe head 702. The waste flows out and is collected in the collection cylinder 601. A conical tube head 702 is provided on the side of the collection cylinder 601, and filter mesh holes 703 are provided at the end and side of the conical tube head 702 to avoid the waste from clogging the conical tube head 702. Even if some of the filter mesh holes 703 are blocked, other filter mesh holes 703 can still filter the waste. When the waste in the collection cylinder 601 is full or reaches a certain level, the collection cylinder 601 can be removed or the collection auxiliary mechanism can be removed as a whole.

[0030] Following the S3 operation steps in Embodiment 1, the collected debris in the collection cylinder 601 is subsequently removed. First, the positioning screw 607 is loosened by the second handle 608, thus releasing the connection between the cover plate 606 and the support sleeve 501. Then, the collection cylinder assembly is lifted directly using the auxiliary lifting ring 609, and the collection cylinder 601 is removed. After removing the debris from the collection cylinder 601, the collection cylinder 601 is then hoisted and placed in the support sleeve 501. Finally, the cover plate 606 and the support sleeve 501 are fixedly connected using the positioning screw 607. The collection auxiliary mechanism is located at the corner of the soft water cellar, which facilitates operation by staff. Compared to setting it in the middle of the soft water cellar, this avoids the problem of staff being unable to operate it.

[0031] The disassembly of the collection auxiliary mechanism involves first disconnecting the fixed connection between the interlocking ring 4 and the support sleeve 501 by loosening the fastening screw 43 using the first handle 44. Then, the collection auxiliary mechanism is lifted and removed as a whole using the auxiliary lifting ring 609, separating the support sleeve 501 from the docking insert 34. The collection auxiliary mechanism is then reassembled by inserting it directly into the interlocking ring 4, ensuring that the docking slot 505 at the bottom of the support sleeve 501 engages with the docking insert 34 on the support docking body 31. This collection auxiliary mechanism, while performing rainwater filtration and collection, also provides auxiliary support for the soft water cellar, further improving its stability.
