[0026] Since the underwater equipment is fixedly connected by the underwater equipment towing device, the selection of the position of the lifting interface 1 must meet the following principles: first, the amount of modification to the exterior of the shell is small; second, it is interchangeable and can be replaced to its original state after the deployment task is completed. According to the above principles, if Figure 2 As shown, the hole cover of the underwater equipment is selected as the lifting interface 1, and CAE stress analysis is performed according to the selected lifting position, which further verifies that the position can meet the design requirements and does not deform during the towing process, that is, the underwater equipment does not bring other interference factors due to the deformation of the shell.

[0027] like Figure 1 , Figure 3 As shown, the towing frame 3 is welded with stainless steel profiles, and angle plates are used for welding at the interface of the underwater equipment to ensure its structural strength.
