Further, the main body of the hydrogen storage tank body is cylindrical, the upper end is closed and provided with a top cover, a hydrogen pipeline interface and a pressure measuring point are arranged on the top cover, silica gel sealing gaskets are arranged between the top cover and the hydrogen storage tank body and between the bottom plate and the hydrogen storage tank body, and the silica gel sealing gaskets are tightly pressed by flange bolts to be fastened and sealed.
Further, the hydrogen storage tank body is a stainless steel tank body.
Compared with the prior art, the utility model, have following advantage and beneficial effect:
1. the hydrogen storage tank is placed in well water, the heat of hydrogen compression is absorbed by water, the temperature of the hydrogen storage tank is kept within a certain range, the pressure fluctuation in the tank is avoided to be overlarge, the hydrogen storage amount is increased, and the safety is guaranteed.
2. The hydrogen storage tank is not subjected to wind, sun, rain and temperature drastic changes, and the service life is longer.
3. Once hydrogen leakage occurs, bubbles appear in water, the bubbles are easy to find, video monitoring can be performed, and safety is high.
4. The tank body adopts a bottom plate split structure, so that the construction of the protective coating resistant to hydrogen permeation in the tank is facilitated, the protective coating is arranged in the tank, and the hydrogen embrittlement caused by the permeation of hydrogen into the tank body (generally made of steel) can be avoided to reduce the structural strength.
