Specifically, referring to fig. 1 and 3, the side net 3 is a hollow cylindrical thin-wall structure integrally formed by adopting profile iron. After the side net 3 is molded, a ring punching die is adopted, and a plurality of meshes are punched on the circumferential side wall of the side net 3, so that the plurality of meshes are uniformly distributed around the side net 3. Meanwhile, the surface treatment is carried out on the side net 3 by adopting an electrophoresis oil spraying process, so that the side net 3 is high in structural strength and not easy to deform, and the reliability requirements of the net cover, the salt spray test and the like are ensured.
