Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in order to overcome the problems such as the difficulty in sealing the motor in the water environment driven by the shaftless wheel rim, the difficulty in reaching several megawatts of the motor power, and the large error of the thrust method for calculating the performance of the blade in open water, a new method is proposed. The belt transmission method transmits the kinetic energy of the motor to the propeller rim, drives the propeller to rotate to generate thrust, and avoids the sealing problem of the power unit in the water environment. At the same time, the suspension method is used to directly measure the thrust, which has the advantages of low energy consumption, low vibration and noise, and thrust Significant advantages such as simple and easy testing

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the present invention is not limited.

[0027] The rim-driven propeller propeller test device provided by the invention has a structure such as figure 1 As shown, it includes a propulsion unit and a support unit. The support unit is mainly composed of a support mechanism and a platform, and the entire propulsion unit is suspended on the platform by the support mechanism.

[0028] The support mechanism includes a receiving plate 8, a space V-shaped bracket 7, an intermediate bearing seat 9, a vertical plate 22, an inclined bracket 12, and a top plate 15, wherein: the receiving plate 8 and the vertical plate 22, the vertical plate 22 and the upper top plate 18 Four-hole thread connection is adopted, and the connection is strengthened by the inclined bracket 12; the middle bearing seat 9 is fixed on both sides of the vertical plate 22. The space V-shape...

Abstract

The invention provides a wheel rim driven propeller thruster test device comprising a thrusting unit and a supporting unit. The supporting unit is mainly composed of a supporting mechanism and a stand. The thrusting unit is mainly composed of a control mechanism, a transmission mechanism and a thrusting mechanism. The whole thrusting unit is suspended on the stand by the supporting mechanism. The wheel rim driving mode of belt pulley transmission and arrangement of belt pulleys in a conduit is adopted so that transmission energy consumption and noise and propeller cavitation can be reduced and thrusting efficiency can be enhanced. Besides, thrust generated by the thrusting unit can be measured in real time by using the lever principle so as to be simpler and more convenient and more accurate than the conventional method by which thrust is reckoned by the open water performance.

Description

technical field [0001] The invention belongs to the field of ship propellers, and in particular relates to a test device for a rim-driven propeller propeller. Background technique [0002] In recent years, with the needs of naval defense construction and the development of water trade, the performance requirements of ship propulsion devices have become higher and higher. The disadvantages of traditional shaft-driven propellers have gradually become prominent, and they can no longer better meet the work requirements. For example, the traditional shaft-driven propeller cabin takes up a lot of space, consumes a lot of energy, it is difficult to control vibration and noise, and the cost of construction and maintenance is high. These defects make all countries turn their attention to more advanced propulsion devices. [0003] At present, pod-type electric propulsion is an advanced ship propulsion method favored by many countries. In this propulsion method, the motor and propeller...
