Greenhouse cascaded heat storage water tank

Abstract

The invention discloses a greenhouse cascaded heat storage water tank which comprises a water tank shell and plastic film sleeves. A plurality of cylindrical cavities are cascaded to form the water tank shell, and one plastic film sleeve is correspondingly placed into each cylindrical cavity. According to the greenhouse cascaded heat storage water tank, a strength structure for bearing water pressure expansion and a leak-proof structure for storing water are divided, namely, the water tank shell is used for supporting the structures, the plastic film sleeves are used for storing water and preventing leakage, and the height of the water tank, leak-proof performances, heat conversion effects and service lives can be better.

Description

technical field [0001] The invention relates to the technical field of greenhouses, and more specifically relates to a greenhouse connected heat storage tank. Background technique [0002] The current heat storage tank has a single production process, only the blow molding process, the tank is not large, the height is not enough, and the heat storage is small; the height is limited, and the water tank produced by the blow molding process can only reach 1.6 meters. The actual need is 2 to 3 meters; the pressure resistance is poor, and the water tank produced by the blow molding process is easy to cause the water tank to break when filled with water, and the waste rate is high; the cost is high, the water tank produced by the blow molding process is expensive, and the promotion and application are restricted by cost. The penetration rate is not high; the heat conversion efficiency is low, the wall of the water tank produced by the blow molding process is thick, the heat conver...
