Among the figure: 1 moving iron core, 2 static iron cores, 3 rotary iron cores, 4,5 permanent magnets, 6 rotating shafts, 8 fixed heads.

Embodiment

Fig. 1 is a structure principle chart of the present invention.The explanation that the present invention's structure working principle is detailed in addition in conjunction with the accompanying drawings.

By accompanying drawing as can be known, this product is the left-right symmetric structure, permanent magnet 4 constitutes rotary iron core with rotary iron core 3, constitute moving iron core with permanent magnet 5 and moving iron core 1, be positioned at rotary iron core top, static iron core 2 is made up of two blocks of ferromagnetic materials, be positioned at the both sides of rotary iron core top, moving iron core, and with two magnetic circuits of its formation, static iron core is fixedlyed connected with both sides fixed head 8, rotary iron core is the center with rotating shaft 6, and freely rotates between static iron core 2 and the moving mandrel lower contact-making surface, and moving iron core moves up and down on the vertical direction that static iron core 2 forms.

When permanent magnetic iron need move iron core and separates, the rotary iron core moving certain angle (this figure is depicted as 60 degree) of can left or turning right, this moment since permanent magnet S-S to occur relative or N-N is relative, show as repulsion between the permanent magnet, cause moving iron core to move upward; When the moving iron core of needs is closed, rotary iron core in the other direction to the right or the identical angle that turns left, at this moment, it is relative with N-S that S-N appears in permanent magnet, shows as suction between the permanent magnet, causes moving iron core to move downward, and reaches situation shown in the figure.

The present invention all can keep its invariant position owing to adopt the magnetic force property of permanent magnet self in the open and close position, and particularly closing a floodgate with operating mechanism in the attracted position is complementary, and without mechanical lock buckle, has simple in structurely, operates reliable characteristics.

The present invention is implementing magnetic circuit conversion necessary forces, the action direction of its power is vertical with permanent magnet generation magnetic force direction, what be equivalent to promptly that active force overcomes is frictional force between them, therefore, the size of power obviously reduces than the magnetic force between the permanent magnet, this is for manual operation or adopt the control operation of stepping motor all to propose lower requirement, helps control and operation.
