Problems solved by technology

However, this utility model patent utilizes the principle of leverage. When the lever is tilted, the lever will deflect up and down for a certain distance during the process of pushing or pulling at both ends, which may cause the direction of the force to change, so that there is a problem of inaccurate measurement results.

Abstract

The invention discloses an underwater robot propeller thrust testing device which comprises a motor holder, a linear guide rail in horizontal arrangement and a supporting frame for supporting the linear guide rail. A first slider is arranged on the linear guide rail in a matched manner, and the motor holder is connected with the first slider through a connection frame and suspended above the linear guide rail through the connection frame; the testing device further comprises a spring arranged between the first slider and the supporting frame and used for resisting movement of the motor holder,and a strain recording device for recording deformation of the spring is arranged on the supporting frame. A force is directly applied to the spring through displacement of the slider, so that transmission process is simplified; motor thrust of an underwater robot can be tested through deformation of the spring, impact of various factors probably existing in the process is eliminated, and the testing device is more accurate in testing effect and simpler in principle and can be applied in various environments with instable water flow.

Description

technical field [0001] The invention relates to the field of underwater assembly testing, in particular to an underwater robot thruster thrust testing device. Background technique [0002] The underwater robot, also known as the unmanned remote control submersible, is a kind of extreme operation robot that works underwater. The underwater environment is harsh and dangerous, and people's diving depth is limited, so underwater robots have become an important tool for developing the ocean. The underwater movement and operation of the submersible is controlled and monitored by the operator on the surface mothership. Rely on the cable to provide power and exchange information to the body. Therefore, the hydrostatic thrust of the submersible is one of the core parameters of the design, and the size of the thrust determines the navigation performance of the submersible. Since the hydrostatic thrust of the propeller is mostly calculated based on the theoretical parameters of the ...
