Abstract (en)
[origin: ES8204033A1] The cover for a swimming pool has a side facing the water and an opposite side facing away. The cover defines an elongated cavity having a single flooding opening facing the water and arranged at one end of the cavity for flooding the pool, the cavity having a venting port at an end thereof opposite to the one end having the flooding opening. A vent valve in the port can close the port and a connection to a source of gas under pressure leads to the cavity for supplying the gas under pressure to the cavity to displace the water in the cavity. The mass of the cover exceeds that of the displaced water in case the cavity or cavities are flooded.
