Abstract

The invention relates to a test device capable of varying water depth to perform performance tests of multiple kinds of water jet propellers under mooring conditions. The device comprises a buoyancy tank (3), a lifting platform (5), a thrust sensor (6) and an electric driving mechanism; the bottom surface of the buoyancy tank (3) is connected with the upper end of a buoyancy tank supporting frame (4); the lower end of the buoyancy tank supporting frame (4) is fixed to the bottom of a test pool; the lifting platform (5) is fixed through lifting platform connecting frames and lifting platform on-shore fixing rods at the left side and right side of the test pool; and one end of the thrust sensor (6) is connected with the electric driving mechanism, and the other end of the thrust sensor (6) is connected with a side wall of the test pool. With one such test device of the invention adopted, the performance tests of different kinds of water jet propellers under water depth varied working conditions can be realized, and time and cost required by the tests can be substantially decreased.

Description

technical field [0001] The invention relates to the field of ship propulsion, in particular to a performance test of a mooring waterjet propulsor under the condition of changing water depth. Background technique [0002] During the navigation of water-jet ships, the propulsion performance of the installed water-jet propulsion will have significant differences with the change of water depth in the navigation waters. At present, the test of waterjet propulsion performance is mainly carried out on conventional test benches such as open water pump test benches, but the existing conventional test benches are difficult to test the performance of water jet propulsion devices in shallow waters, and cannot fully and accurately simulate Actual operating conditions of water jet propulsion. Therefore, it is necessary to design The invention relates to a propulsion performance test device which can realize the variation of water jet propulsion with water depth in mooring state. Conte...
