Water-freezing-preventive device and system
The invention discloses a water-freezing-preventive device and system. The water-freezing-preventive device comprises a water collection tank, a water collection tank piston connected with a piston handle, and a handle fixing device, the water collection tank is positioned below the ground, a water inlet and outlet is arranged at one end, opposite to the piston handle, of the water collection tank, the water inlet and outlet is in waterway connection with an underground water pipeline, and the handle fixing device is used for being detachably and fixedly connected with the piston handle when the water collection tank piston moves to a preset water collection quantity position. The water collection tank is positioned below the ground, and the water inlet and outlet and the underground water pipeline are in waterway connection, so that at winter night, water collection capacity is enabled to be high enough by closing a water-supply master valve, opening a water outgoing valve and pulling the piston handle to a certain height from the bottom of the water collection tank; in this way, due to action of atmospheric pressure difference, water in the underground water pipeline flows back below the ground, and probability of freezing of a water delivery pipeline above the ground at winter night is lowered.
