Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1

As shown in fig. 1-3, the utility model provides a test platform for underwater vehicle retrieves sets up in the kerve 71/moon pool department of test ship 7, provides the mounted position for retrieving underwater vehicle's arm 8 and recovery tube 4 to make it can be in under the real environment, so that carry out under the real environment simulation test that underwater vehicle was retrieved to arm 8, with the reliability of the work of detection arm 8.

Specifically, the test platform comprises: base 1, mounting bracket, arm frame 2, recovery pipe installation component 3 and thrust rod 6, wherein, base 1 is formed by many I-steel welding, and steel sheet net 11 is laid on its surface. The mounting frame comprises a cross beam 52 and a support 51, the bottom end of the support 51 is fixedly connected with the base 1 through a bolt, the top end of the support is connected with the cross beam 52, and two ends of the cross beam 52 are respectively fixed on decks on two sides of the tail groove 71/moon pool. The top of the beam 52 is provided with a plurality of lifting lugs 53 to facilitate the laying of the test platform.

The bottom of the mechanical arm base 2 is fixedly connected with the base 1 through bolts, the mechanical arm base 2 is located on one side, away from the test ship 7, of the base 1, and after the mechanical arm 8 is installed, the mechanical arm 8 is horizontal so as to capture underwater navigation bodies.
