Here’s my imaginative guess!

The image with the red cloth is a seal that slides in the outer tube, the loose bit inside is a “check valve”, the end with all the holes is submerged in water (it has small protrusions so it doesn’t sit against something and block the holes), the inner tube is pulled “up” (think bicycle pump) making the check valve close drawing water in, then the inner tube is pushed down forcing the valve to close and water to be forced (sprayed) out of the top of the inner tube.

Repeat as fast as possible if it’s a fire! Or something like that...
