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, the valve opens and water is then forced (sprayed) out of the top of the inner tube (with maybe another simple flap valve near the intake?...). Or something like that...

Repeat as fast as possible, there’s a fire!
