Hydrostatic thrust test platform for underwater propeller

Abstract

The invention relates to a hydrostatic thrust test platform for an underwater propeller. The hydrostatic thrust test platform comprises a pool, a walking board, a plurality of span beams and a thrust test mechanism, a mounting seat I is arranged in the circumferential direction of the water tank; the walking board and the span beam are arranged above the water pool through first installation bases. The two sides of the walking board and the two sides of the span beam are provided with second installation bases. The thrust testing mechanism comprises a rotating shaft and a pressure gauge mounting seat; bearing seats connected with the mounting seats II are arranged at the two ends of the rotating shaft; a rotating force arm and a pressure arm are fixed on a shaft body of the rotating shaft; a hoop is arranged at the free end of the rotating force arm; two ends of the pressure gauge mounting seat are mounted on the mounting seat II; a pressure gauge is fixed on the pressure gauge mounting seat. The device has the advantages that the horizontal position of the thrust testing mechanism is adjustable, and the underwater position of the propeller can be adjusted at will in cooperation with the rotating force arm with the adjustable length. The equipment can simulate the environment when the underwater water inlet side and the underwater water outlet side of the propeller are blocked and the propeller is close to the water bottom; and furthermore, the influence of the environment on the thrust is read.

Description

technical field [0001] The invention relates to the field of underwater thrusters, in particular to a hydrostatic thrust test platform for underwater thrusters. Background technique [0002] The underwater thruster is the power device of most underwater equipment, and its hydrostatic thrust is the core design parameter. Usually the static water thrust of the underwater thruster is calculated, but due to various resistances, errors, etc., the actual value often deviates from the calculated value, and this deviation may affect the service of the underwater equipment. overall performance. Therefore need a kind of equipment that can accurately measure the thrust value of underwater thruster under still water condition. [0003] At present, there are very few schemes about the thrust test of underwater thrusters that can be consulted, and the structure of the schemes that can be consulted has the following defects: 1.

Problems solved by technology

[0003] At present, there are very few schemes about the thrust test of underwater thrusters that can be consulted, and the structure of the schemes that can be consulted has the following defects: 1. When replacing the underwater thruster, the fixing frame needs to be taken out of the water for replacement, which is very inconvenient; 2. The structure of the scheme is too complex, resulting in more interactions between the structural parts, which may have a certain impact on the test results and lead to unplanned errors; 3. The position of the thruster under water is affected by the fixed installation of the structural parts The impact cannot be moved. When it is necessary to change the position of the underwater propeller in the water, another set of test structures can only be recreated, which is time-consuming and laborious
