[0015] Figure 1 is the front view of the utility model;

[0016] Figure 2 is the side view of the utility model. DETAILED DESCRIPTION

[0017] Referring to the drawings, the utility model specifically adopts the following implementation ways: including steel tank body lifting lug 1, protective band 2 trunnion 3, base 4, angle steel protective band 5, inner guard plate 6, angle steel reinforcing rib 7 and steel tank body 8, one side of steel tank body 8 is equipped with lifting lug 1, the lateral wall of steel tank body 8 is equipped with protective band 2, trunnion 3 is installed on protective band 2, the bottom of steel tank body 8 is connected with base 4, the inner top end of steel tank body 8 is equipped with angle steel protective band 5, the inner lower part of steel tank body 8 is equipped with inner guard plate 6, and the outer bottom of steel tank body 8 is equipped with angle steel reinforcing rib 7. The number of protective band 2 is six, and protective band 2 embraces steel tank body 8 and is distributed at equal intervals on the lateral wall of steel tank body 8. The number of trunnion 3 is two, and trunnion 3 is symmetrically arranged on one of the protective bands 2 on the lateral wall of steel tank body 8. The number of base 4 is five, and base 4 is arranged at equal intervals on the bottom of steel tank body 8. The number of angle steel protective band 5 is two, and angle steel protective band 5 is installed on the inner top wall and one side wall of steel tank body 8. The number of angle steel reinforcing rib 7 is three, and angle steel reinforcing rib 7 is longitudinally arranged on the bottom of steel tank body 8, one of angle steel reinforcing rib 7 is arranged at the center of the bottom of steel tank body 8, and the other two are symmetrically arranged on the two sides of the center line.
