Abstract
The utility model discloses a kind of small underwater propeller hydrostatic thrust test devices.Propulsion test device is mainly by rack, axis, propeller clamping device, linear guide, bascule and dynamometer composition.When use, propulsion test device is placed in test pools, dynamometer mounting surface is higher than the water surface, after starting propeller, propeller screw paddle generates thrust and drives clamping device horizontal movement on rectilinear orbit, when clamping device withstands bascule one end, bascule is rotated centered on axis, due to equal arm of forces principle, the numerical value of power can be read in the dynamometer of the bascule other end, this numerical value is propeller hydrostatic thrust.
Description
Technical field
The utility model relates to underwater equipment technical fields, are a kind of underwater propeller hydrostatic thrust test devices.
Background technique
Small underwater vehicle propeller hydrostatic thrust is one of the core parameter of vehicle design, and the size of thrust determines
The navigation performance of vehicle.It is and true since propeller hydrostatic thrust according to propeller theory coaptation mostly to obtain
Thrust under environment has certain deviation, so the propeller thrust accurately measured under true water environment has weight to vehicle design
Want meaning.But retrieval " test of underwater propeller thrust or underwater propeller thrust measurement " and " submersible machine in patent retrieval
Thrust " does not find related data, recognizes during consulting related literatures, and small underwater propeller hydrostatic thrust is surveyed
It is fewer that data is set in trial assembly, therefore designs a kind of small underwater propeller hydrostatic thrust test device and be highly desirable, and has very
Good application prospect.
Summary of the invention
To solve the above-mentioned problems of the prior art, the utility model proposes a kind of small underwater propeller hydrostatic thrusts
Test device.
The technical solution of the utility model is：A kind of small underwater propeller hydrostatic thrust test device, mainly by rack,
Axis, propeller clamping device, linear guide, bascule and dynamometer composition.The rack includes bracket, support plate, connection
Plate, U-shaped frame and rectangular steel tube provide installation site for components such as propeller clamper, linear guide, bascule, dynamometers,
It is the body structure portion of the propulsion test device.
Propeller clamper is able to satisfy the steady of different size propellers within the scope of certain diameter as the fixed device of propeller
Gu clamping, and ensure that both propeller and propeller clamper can the horizontal smooth linear movements in linear guide.Propulsion to be measured
Entire propulsion test device is placed in test pools by device after being stabilized on propeller clamper, and dynamometer is fixed on rack
Portion's installation site, dynamometer push-pull rod are connected with bascule upper end.U-shaped push rod top when test, on propeller clamper
The firmly lower end of bascule, when startup power supply makes propeller horizontal rectilinear motion generate thrust, propeller pushes U-shaped push rod to make
Arm bar rotation, bascule rotation center line make it to dynamometry using water-sealed bearing to reduce the frictional dissipation of lever rotating type
As a result influence is as small as possible.By the transmitting of bascule, bascule upper/lower terminal generation displacement is equal, lever
The thrust that lower end is subject to is identical as the pulling force of upper end dynamometer, and the numerical value of power shown by dynamometer is that propeller hydrostatic pushes away at this time
