A Propeller Open Hydrodynamic Instrument

Abstract

The invention provides an open water dynamometer of a propeller. The dynamometer comprise a first rope, a second rope, a rack, a second shaft cylinder, a first shaft cylinder, a support rod, a fourth cylinder, a double-head cylinder, a clamp plate, a fifth cylinder, an electromagnet, a first fish eye bearing, a third cylinder, a connection plate, a second slide block, a second fish eye bearing, a second cylinder, a second slide rail, bellows, a first cylinder, a first pin shaft, a first hollow part, a first support plate, a scissors fork arm, a second hollow part, a second support plate, a second pin shaft, a motor, a support column, a first slide rail, a first slide block, a main rotation shaft, a main bevel gear, a first flange bearing, a third slide block, a third slide rail, a second flange bearing, an auxiliary bevel gear, an auxiliary rotation shaft, a controller, a rolling ball, a support and a rolling wheel. The rolling ball is installed under the rack. The support is installed on the left side of the rack. The rolling wheel is installed on the rack. A second rope is installed on the rolling wheel. The first rope is installed on the second rope. The dynamometer is advantageous in that the dynamometer is suitable for all kind of sizes of impellers, and heights of the impellers can be adjusted during a test.

Description

technical field [0001] The invention relates to a propeller open water dynamic instrument, which belongs to the technical field of ship equipment. Background technique [0002] The manufacture of ships is a huge project. In the design and manufacturing stages, ship model tests are required to avoid detours in the ship manufacturing process and save a lot of time and money. The chuck of the propeller open hydrodynamic instrument in the prior art There is no adjustment device in the part, which is not suitable for propellers of various sizes, and the height of the propeller cannot be adjusted during the test, so comprehensive measurement data cannot be obtained. In order to solve the above difficulties, it is necessary to develop a propeller open hydrodynamic instrument suitable for propellers of various sizes, and the height of the propeller can be adjusted during the test. Contents of the invention [0003] The purpose of the present invention is to provide a propeller op...
