Non-negative pressure water supply device

The utility model relates to a non-negative-pressure water supply device, and aims to solve the problems that a non-negative-pressure flow stabilizing tank fixed on the ground is easy to shake in the water inlet and drainage process, so that the non-negative-pressure flow stabilizing tank is unstable, the connection state of an instrument on the non-negative-pressure flow stabilizing tank and a pipeline is seriously influenced, and the water supply efficiency is high. The non-negative-pressure water supply device comprises a non-negative-pressure pressure stabilizing assembly and energy absorption assemblies symmetrically installed on the two sides of the bottom end of the non-negative-pressure pressure stabilizing assembly, each energy absorption assembly comprises a cross beam, buffering assemblies are fixedly installed at the two ends of each cross beam in a welded mode, and each buffering assembly comprises a base. According to the non-negative pressure steady flow tank, shaking is absorbed in a double-ar
