Butterfly-shaped wave-resistance plate structure of tank semi-trailer

The invention discloses a butterfly-shaped wave-resistance plate structure of a tank semi-trailer. The butterfly-shaped wave-resistance plate structure comprises butterfly-shaped wave-resistance plates and butterfly-shaped strengthening rings. The butterfly-shaped strengthening rings are welded to the butterfly-shaped wave-resistance plates, and the butterfly-shaped wave-resistance plates and the butterfly-shaped strengthening rings are welded to the interior of a semi-trailer tank body. According to the butterfly-shaped wave-resistance plate structure of the tank semi-trailer butterfly-shaped wave-resistance plate structure, the wave-resistance effect of the wave-resistance plates is further improved through the tank body of the butterfly-shaped wave-resistance plate structure, meanwhile, double-face welding can be achieved, sealing performance is better, the interior of the tank body is supported by the butterfly-shaped wave-resistance plate structure, and therefore the tank body is not likely to be deformed or pulled to be cracked.
