Embodiment
In the present embodiment, with reference to Fig. 1, this seesaw type twin coil magnetic TRT comprises soft magnetic material 1, permanent magnet 2, elastic device 3, iron core 4 and coil 5; Soft magnetic material 1 is the long plate shape structure.Permanent magnet 2 can adopt magnet steel commonly used such as neodymium iron boron, and the direction of magnetization is the upward and downward among the figure, and the position of the N utmost point and the S utmost point can be changed, and coil 5 inner magnetic directions also can reverse during transposing.The peak of permanent magnet 2 forms a seesaw structure than small distance and the soft magnetic material 1 of upper end that the exit of both sides iron core 4 exceeds in one section 5mm.The highest point that another kind of similarly mode is a permanent magnet 2 is identical with the exit height of both sides iron core 4, and additional projection in the stage casing of soft magnetic material 1 is formed seesaw structure (not shown) with iron core 4 and coil 5.Elastic device 3 is optional, and said elastic device is spring or shell fragment, and effect can be explained in Fig. 2.Suppose that initial condition is consistent with Fig. 1, under this state, because the magneto resistive ratio soft magnetic material 1 of air is much bigger with iron core 4, most magnetic lines of force all pass through from the loop that soft magnetic material 1 and iron core 4 are formed, and the magnetic direction of coil 5 inside is shown in arrow among Fig. 1.
Fig. 2 is the state when an end that upwarps among Fig. 1 is pressed.When an end that upwarps among Fig. 1 was pressed, this end was connected with iron core 4 exits of below, forms the field circuit that magnetic resistance is very little; The other end promptly is lifted simultaneously, and the soft magnetic material end of contact and iron core exit separate originally, and field circuit magnetic resistance originally suddenly increases, and can be regarded as breaking off.Magnetic direction in the coil 5 is as shown in Figure 2 at this moment, and visible under new field circuit effect, the magnetic field size in the coil 5 is identical; Direction reverses; Caused the variation of a bigger magnetic flux, according to the law of electromagnetic induction, the variation of magnetic flux makes in the coil two ends and produces voltage; Can draw, or behind over commutation, supply power to element to energy-storage travelling wave tube.Optional elastic device is had an effect for 3 this moments, if having elastic device 3, is pressing after release removes, and elastic device can recover the state of Fig. 1 with being retracted by an end that upwarps downwards.In this process, the magnetic circuit of connection breaks off, and the magnetic circuit of disconnection is communicated with, and the magnetic direction in the coil 5 takes a turn for the worse once more, can once generate electricity once more.Elastic device 3 can make once to press and produce twice power generation process, and generating efficiency is improved, but has also increased the complexity of structure, during actual enforcement, can determine according to demand.
Fig. 3 is the situation that elastic device 3 is not installed, and press an end that upwarps this moment, and this end promptly is attracted on the iron core that is magnetized, and is pressed up to the other end, makes this hold perk once more.Coil is divided into the first coil 5-1 and the second coil 5-2, and these two parts are chained together.The baffle plate 6 of coil 5 sides can be used as fixed coil and the usefulness that is connected base.
Shown in Fig. 4 to Fig. 6, be second embodiment of this seesaw type twin coil magnetic TRT.The main distinction of this embodiment and first embodiment is iron core 4 and coil 5 have been moved on to the top as movable member.Said soft magnetic material two ends are provided with upwardly extending convexity.Permanent magnet 2 can adopt magnet steel commonly used such as neodymium iron boron, and the direction of magnetization is the upward and downward among the figure, and the position of the N utmost point and the S utmost point can be changed, and coil 5 inner magnetic directions also can reverse during transposing.The peak of permanent magnet 2 forms a seesaw structure than small distance and the iron core 4 of upper end that the convexity of both sides soft magnetic material 7 exceeds in one section 5mm.The highest point that another kind of similarly mode is a permanent magnet 2 is identical with the height of projection of both sides soft magnetic material 7, and additional projection in the stage casing of iron core 4 is formed the seesaw structure with coil 5.Elastic device 3 is optional, and effect can be explained in Fig. 5.Suppose that initial condition is consistent with Fig. 4, under this state, because the magneto resistive ratio soft magnetic material 7 of air is much bigger with iron core 4, most magnetic lines of force all pass through from the loop that soft magnetic material 7 and iron core 4 are formed, and the magnetic direction of coil 5 inside is shown in arrow among Fig. 4.
Fig. 5 is the state when an end that upwarps among Fig. 4 is pressed.When an end that upwarps among Fig. 5 was pressed, this end was connected with soft magnetic material 7 convexities of below, forms the field circuit that magnetic resistance is very little; The other end promptly is lifted simultaneously, and the soft magnetic material end of contact and iron core exit separate originally, and field circuit magnetic resistance originally suddenly increases, and can be regarded as breaking off.Magnetic direction in the coil 5 is as shown in Figure 5 at this moment, and visible under new field circuit effect, the magnetic field size in the coil 5 is identical; Direction reverses; Caused the variation of a bigger magnetic flux, according to the law of electromagnetic induction, the variation of magnetic flux makes in the coil two ends and produces voltage; Can draw, or behind over commutation, supply power to element to energy-storage travelling wave tube.Optional elastic device is had an effect for 3 this moments, if having elastic device 3, is pressing after release removes, and elastic device can recover the state of Fig. 4 with being retracted by an end that upwarps downwards.In this process, the magnetic circuit of connection breaks off, and the magnetic circuit of disconnection is communicated with, and the magnetic direction in the coil 5 takes a turn for the worse once more, can once generate electricity once more.Elastic device 3 can make once to press and produce twice power generation process, and generating efficiency is improved, but has also increased the complexity of structure, during actual enforcement, can determine according to demand.
Fig. 6 is the situation that elastic device 3 is not installed, and press an end that upwarps this moment, and this end promptly is attracted on the soft magnetic material that is magnetized, and is pressed up to the other end, makes this hold perk once more.Coil is divided into the first coil 5-1 and the second coil 5-2, and these two parts are chained together.
Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
