Description

Technical Field

[0001] The utility model relates to a storage device, in particular to a solar circulating hot water storage device, belonging to the technical field of storage devices. Background Art

[0002] In some industrial parks or industrial plants, in order to make full use of solar energy, more solar water heaters are often installed on the open space in the park or on the roof of the plant. Large-area solar heat is used to generate more hot water, which can be stored for use by employees in the park or plant in their daily lives. In order to store more hot water, special hot water storage equipment is required.

[0003] In the prior art, a solar water storage tank with a sterilization function disclosed in announcement number CN203238058U is also aimed at a water storage device, in which a heating tube and a sterilization lamp connected to a battery are arranged inside the tank body; the water quality can be heated and disinfected by the heating tube and the sterilization lamp to kill bacteria that are not resistant to high temperatures, and the residual bacteria can be eliminated by the sterilization lamp. The heating tube and the sterilization lamp can be powered by the solar panels and the batteries to reduce energy consumption. However, in actual use, the water in the tank is sterilized to ensure the safe use of the water body. However, for the entire storage device, since more water needs to be stored, a larger tank body needs to be designed, such as the common tank water tank on the market. When installing, it is necessary to focus on the stability of the installation. And after a lot of hot water is filled in the tank, how to make the tank body maintain the structural firmness and not easily crack at the welding point. For the existing tank-shaped solar water storage tank, its structure is often square or cylindrical. When installing the water tank, in order to prevent corrosion to the bottom of the tank body, it is necessary to set the tank body in a suspended state. However, directly fixing the tank body in a suspended state will cause the center of gravity of the tank body to rise. When a lot of hot water is stored in the tank, it is easy to cause shaking and tilting. In order to prevent the bottom of the tank from cracking due to storing a lot of hot water, it is often stabilized by pulling inside the tank. However, due to the long-term storage of hot water in the tank, the pull rods used for pulling the side walls of the tank body are easily corroded and rusted, which will cause some harmful substances in the water body. After a long period of corrosion, the effect of pulling inside will also deteriorate, affecting the stability of the tank body. Summary of the invention
