Reservoir system capable of being automatically opened and closed according to water storage degree

The invention belongs to the technical field of reservoirs, and provides a reservoir system capable of being automatically opened and closed according to the water storage degree, which comprises a water inlet pipe, a plurality of reservoirs, a plurality of automatic switches and a plurality of water level detectors. The plurality of reservoirs are arranged in parallel; and each reservoir is communicated with the water inlet pipe through a water inlet branch. The plurality of automatic switches are correspondingly arranged on the plurality of water inlet branches respectively, and are electrically connected in series in sequence according to the arrangement sequence of the corresponding reservoirs. The plurality of water level detectors are electrically connected with the corresponding automatic switches; the water level detector responds to the contact between the water level detector and the water surface in the reservoir and sends a first electric signal to the corresponding automatic switch, the correspon
