Distribution and recovery method of large underwater test equipment

Abstract

The invention provides a distribution and recovery method of large underwater test equipment. The method comprises the following steps: multiple lifting rod sections are connected to form a lifting rod with a set length; a rotary driving device is connected to one end of the lifting rod; the other end of the lifting rod is connected with assembled test equipment; a flange plate is arranged at theend, connected with the rotary driving device, of the lifting rod; multiple lifting ropes connected to the flange plate are connected to the test equipment; a crane lifting hook is connected with therotary driving device; the lifting rod and the test equipment are lifted through the rotary driving device; a lifting bridge is placed down; the test equipment is connected to a fixture of the liftingbridge through the lifting rod and the rotary driving device; the crane lifting hook is released; a motor of the rotary driving device drives the test equipment to rotate through the lifting rod; andwhen the test equipment is recovered, the crane lifting hook is connected with the rotary driving device to lift up the test equipment. Compared with a traditional movable bearing platform, the lifting bridge is higher in bearing capacity and better in flexibility.

Description

technical field [0001] The invention relates to underwater tests, in particular to a method for deploying and recovering large-scale underwater test equipment. Background technique [0002] The underwater test equipment is usually loaded on the working ship on the water, and it is deployed in the water and recovered to the working ship by using the ship-borne lifting equipment in the designated water area, such as A-frame, driving crane, crane, etc. [0003] The length of underwater test equipment is generally not more than 10 meters, and the deployment and recovery operations are less difficult. Therefore, the traditional deployment and recovery methods can better complete the task. However, for large-scale underwater test equipment, the total length is 20 to 60 meters, and it needs to be assembled on site before being lowered into the water. The volume of the test equipment is relatively large, which is limited by factors such as the general layout of the operation vessel ...
