Flood Sucker

Properly Described, this is a Flood Water Suction Bag.

An expanding rubber bag (more fun with wheel inner tubes?), that is deployed upon excess ground water caused by flooding, where it floats on the surface, and sucks up the water through tubes in the bottom until the bag is full, so that the water is gathered and stored in manageable quantities as effective solid blocks, where, like my idea of the Ice block flood buster, they can be stacked, and arranged to remove the water from areas where it would do damage to the soil or ground, and even be used to construct flood barriers against the water you cannot cope with by this method alone.
Only here, no expensive freezing or pumping equipment is required, just the initial effort to compress each bag flat before use, buy means of a couple of guys, or other suitable applied weight squashing the top and bottom together to collapse the bag, where it is locked in place ready for deployment, when it is released.

Each one is comprised of the aforementioned top, and bottom rectangular frame pieces (1a), made of tough rigid plastic (recycled?), which enclose, and are bonded to, the rubber bag (1b+1c), which is the part which expands, and contains the water. By expelling the air from within when collapsing the bag ready for use, a vacuum is created within, until either air, or water replaces it.

The suction is achieved by means of the internal end, or corner pillars of suitably flexible, bendy, and springy material (1i), being bent double internally through the compression, but these naturally want to spring back to their natural form of being entirely straight pillars which define the upright edges or sides of the fully expanded bag.

When on the water, with the open tubes, like straws, in the bottom in contact with the water (1ii), the central locking wedge thing (3), which has held the two ends together, and the bag compressed, is released, and the bag begins to expand (2 (with cutaway sections in red, to show the water filling inside)), with the force of these internal corner pillars straightening out forcing the bag open, sucking in the water.

As the bag begins to fill, the sideways force of the now internal water accumulates to assist the rectification of the pillars, and the full expansion of the bag, allowing it to fill with water more, over the level of the external flood water (3i), until the bag presents the appearance of a solid block of contained water, as a solid body. This means that the bag sinks as it fills, until it comes to rest on the bottom (3ii), that is, on the field or ground you want cleared of water, where it then stays due to this now single body of water being heavy enough to resist the external forces of the flood water around it, of which it is now a separate entity.

If each bag can expand to five times it's compressed dimensions, then a lorry load of these compressed bags can collectively store five times the volume of the lorry trailer it came on, which, when considered in terms of a farmer's field being covered in about a foot deep of water, then with bags that can each expand to being four feet high, by four feet long, and six feet deep, a lorry load ought to be able to clear an entire farm's worth of fields in terms of affected area.

Just throw them on the water, release the lock, and let them suck up all the water by themselves!

When you come back you will have a scattering of blocks of contained water, and the rest of the field/ ground free of flooding.
