Problems solved by technology

[0002] Usually, the linear generator is installed horizontally during the test. In this way, there is a unilateral pressure caused by the influence of gravity and other factors on the mover of the linear generator, which causes the bearing to be stressed and wear quickly, especially for large-scale Linear generators, this situation will be more serious

Embodiment 1

[0019] Such as figure 1 As shown, a linear generator test device includes a support 1, a steering pulley block 2, a connecting rope 3, and a displacement adjustment turntable 4 and a drag motor 5; To make the displacement adjustment turntable 4 rotate and provide the motive force for the linear generator; the displacement adjustment turntable 4 is provided with a plurality of adjustment holes; the linear generator is vertically installed on the motor bracket 1 through the stator, and the bracket 1 is also installed with The steering pulley block 2; the connecting rope 3 straddles the steering pulley block 2, and one end is connected with the mover of the linear generator, and the other end is connected with the displacement adjustment turntable 4. The driving motor 5 is a speed-regulating motor, which is used to change the reciprocating operation period of the linear generator by adjusting the rotating speed of the driving motor 5 . The adjustment holes on the displacement a...

Embodiment 2

[0021] The difference from Embodiment 1 is that the displacement adjustment turntable 4 is provided with three adjustment holes, and the three adjustment holes are radially and evenly arranged on the side of the center of the displacement adjustment turntable 4 .

[0022] The said displacement adjusting turntable 4 can also be provided with 10 adjusting holes, which is yet another embodiment.

Abstract

The invention relates to a device for testing a linear generator. The device comprises a support, a steering pulley block, a connecting rope, a displacement adjustment turntable and a dragging motor, wherein the dragging motor is in transmission connection with the displacement adjustment turntable and is used for driving the displacement adjustment turntable to rotate and providing motive power for the linear generator; a plurality of adjusting holes are formed in the displacement adjustment turntable; the linear generator is vertically arranged on a motor support through a stator, and the steering pulley block is also arranged on the support; and the connecting rope strides over the steering pulley block, one end of the connecting rope is connected with an active cell of the linear generator, and the other end of the connecting rope is connected with the displacement adjustment turntable. The device for testing the linear generator has the advantages that: the reciprocating period of the linear generator can be changed by adjusting the rotating speed of the dragging motor, and the reciprocating stroke of the linear generator can be changed by changing positions of the adjusting holes of the displacement adjustment turntable; and the active cell of the linear generator only suffers from a tensile force and the gravity in the vertical direction during a test, the test effect of the device is good, and the efficiency of the device is high.

Description

technical field [0001] The invention relates to a test device for a linear generator, which is particularly suitable as a test device for simulating a direct-drive wave energy power generation system. Background technique [0002] Usually, the linear generator is installed horizontally during the test. In this way, there is a unilateral pressure caused by the influence of gravity and other factors on the mover of the linear generator, which causes the bearing to be stressed and wear quickly, especially for large-scale Linear generators, this situation will be more serious. People have hoped for a long time to overcome the above shortcomings, simulate the operation of the reciprocating motion of the linear generator in different cycles and different strokes, and avoid the linear generator's mover being affected by gravity and other factors when the linear generator is installed horizontally. Unilateral pressure. Contents of the invention [0003] The invention provides a ...
