Description

Technical Field

[0001] The invention belongs to the field of underwater acoustic transducers, and in particular relates to a moving magnetic drive magnetic circuit and a hydrostatic pressure-resistant high-power double moving magnetic drive stack. Background Art

[0002] Low-frequency sound waves, especially ultra-low-frequency sound waves with a frequency below 200Hz, have a very huge utilization value. On the one hand, with the widespread application of anechoic tiles and the development of vibration and noise reduction technology, it is becoming increasingly difficult to detect submarines using passive sonar or high-frequency active sonar, so using ultra-low-frequency sonar for active detection has become an effective means; on the other hand, when sound waves propagate in water, the lower the frequency of the sound waves, the slower the attenuation, so ultra-low-frequency sound waves can propagate over long distances in water, which is conducive to increasing the effective distance of sonar. In the civilian field, ultra-low-frequency sound waves are also widely used in the fields of marine acoustic tomography and geoacoustic research.

[0003] The generation of ultra-low frequency sound waves in water depends on ultra-low frequency underwater acoustic transducers. Generally speaking, the lower the frequency of the transducer, the larger the size and weight. Transducers made of traditional driving materials such as piezoelectric materials and magnetostrictive materials are very large in size and weight if ultra-low frequency emission is to be achieved. Electro-magnetic drive is an ideal ultra-low frequency transducer drive source, and its basic principle is based on electromagnetic interaction. Electro-magnetic transducers can usually be regarded as single-degree-of-freedom vibration systems. The main working mode of the transducer is the piston-like vibration of the radiating surface and its connecting parts. The stiffness of the vibration system is provided by the elastic elements of the transducer. Since the stiffness can be designed, ultra-low frequency emission can be easily achieved. Common electro-magnetic drive transducers include electric transducers, dynamic magnetic transducers, etc. The dynamic magnetic drive has a larger limit power and is more suitable as a drive source for high-power ultra-low frequency transducers. Traditional moving magnetic transducers are air-backed and have a maximum operating depth of tens of meters. As my country's marine research is increasingly moving towards the deep sea, the demand for deep-sea transducers is becoming more and more urgent. In order to increase the operating depth of the transducer, the transducer drive part needs to be watertightened to facilitate the production of an overflow transducer, thereby increasing the working depth of the transducer.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] See also Figure 1To illustrate the present embodiment, a moving magnetic drive magnetic circuit comprises a permeable core 1, a coil 2 and a permanent magnet array, wherein the number of the permeable cores 1 is two, and both of the two permeable cores 1 are of C-shaped structure. The openings of the two C-shaped permeable cores 1 are arranged opposite to each other, and both ends of each permeable core 1 are sleeved with the coil 2. The permanent magnet array comprises a first permanent magnet 3 and a second permanent magnet 4 of two different sizes, a large-sized second permanent magnet 4 is placed in the middle, and small-sized first permanent magnets 3 are placed on both sides. The second permanent magnet 4 in the middle has a magnetic pole direction opposite to the first permanent magnets 3 on both sides. The first permanent magnet 3 and the second permanent magnet 4 are both of rectangular plate-like structure, and the magnetic pole directions of the first permanent magnet 3 and the second permanent magnet 4 are opposite. The magnetic pole direction of the permanent magnet array and the corresponding current flow direction of the coil 2 are in the opposite direction. Figure 1 It is marked in the figure that the permanent magnet array is arranged in the middle of the two permeable cores 1 and the connecting gap between the first permanent magnet 3 and the second permanent magnet 4 is located in the middle of the magnetic pole of the permeable core 1. This ensures that when the magnetic circuit is in a static state, that is, when no current flows in the coil 2, the static adsorption forces of the permeable cores 1 on both sides of the permanent magnet array can offset each other.

[0029] See also Figure 2-8 The present embodiment is described, a high-power dual-moving magnetic drive stack resistant to hydrostatic pressure includes two single-moving magnetic sub-drive stacks, the single-moving magnetic sub-drive stacks include a moving magnetic drive magnetic circuit and a magnetic circuit fixing structure, the magnetic circuit fixing structure includes a permanent magnet mounting frame 8 and a mounting frame 10, a mounting through hole 9 is provided in the middle of the permanent magnet mounting frame 8, a permanent magnet array is arranged in the mounting through hole 9, the permanent magnet mounting frame 8 is arranged in the middle of the mounting frame 10, both ends of the permanent magnet mounting frame 8 are respectively connected to steel leaf springs 11, both ends of the steel leaf spring 11 are connected to the mounting frame 10, the coil 2 includes a coil skeleton 6 and a wire, the wire is wound on the coil skeleton 6, the coil 2 is watertightly potted, the coil skeleton 6 is sleeved on the magnetic core 1, a magnetic core 1 is arranged at the upper and lower ends of the mounting frame 10, and the magnetic core 1 is connected and fixed to the mounting frame 10 through a crossbeam 14.

[0030] The mounting frame 10 is made of aluminum. The mounting frame 10 and the crossbeam 14 are used to fix the magnetic core 1 in the dynamic magnetic drive magnetic circuit. The permanent magnet mounting frame 8 is used to place the permanent magnet array. The steel leaf spring 11 is used to limit the permanent magnet array to prevent the permanent magnet from being adsorbed on the magnetic core 1. The structure and size of the mounting frame 10 are determined according to the size of the magnetic circuit. The mounting frame 10 cooperates with the crossbeam 14, the steel leaf spring 11 and the steel leaf spring pressure block to fix the magnetic circuit to ensure that the various parts of the magnetic circuit will not be offset.

[0031] like Figure 2As shown, a plurality of core slits 5 are provided on both sides of the permeable core 1. In order to reduce eddy current loss, the permeable core 1 is slit. Since eddy current always flows on the surface of the conductor, the surface area of ​​the core is increased after slitting, resulting in a longer eddy current flow path, an increased eddy current flow resistance, and reduced loss, thereby improving the uniformity and magnetic field strength of the magnetic field in the magnetic gap of the drive stack and improving the working efficiency of the drive stack. The more slits there are, the better the eddy current suppression effect. The permeable core 1 is provided with a slot, and the crossbeam 14 cooperates with the slot provided on the permeable core 1, and the crossbeam 14 is connected to the mounting frame 10.

[0032] like Figure 3 As shown, the coil frame 6 is provided with a watertight groove 7, and watertight potting treatment is performed using potting epoxy, which can ensure watertightness and resistance to hydrostatic pressure. The potting uses a specially designed potting mold, and the coil frame 6 is also used as a part of the mold. During potting, the epoxy will fill the watertight groove 7, making the watertight effect of the potting solution more reliable.

[0033] like Figure 4 As shown, the permanent magnet array is bonded to the permanent magnet mounting frame 8 using epoxy glue, and the permanent magnet mounting frame 8 and the permanent magnet array are bonded as one with the bonding epoxy glue during installation. During bonding, the first permanent magnet 3 and the second permanent magnet 4 are first arranged according to the designed magnetic pole direction, and then a layer of bonding epoxy is evenly applied to each surface of the upper and lower and both sides of the permanent magnet array, and then the permanent magnet array is placed in the mounting through hole 9, and the two large planes of the permanent magnet mounting frame 8 are clamped with a clamp to ensure that the permanent magnet array is in close contact with the permanent magnet mounting frame 8. In order to prevent the permanent magnet array from demagnetizing, the bonding and drying temperature cannot be too high. The first permanent magnet 3 and the second permanent magnet 4 in the permanent magnet array are both neodymium iron boron rare earth permanent magnets.

[0034] The end face of the permanent magnet mounting frame 8 and the side face of the mounting frame 10 are provided with slots, and the steel leaf spring 11 is clamped in the slots. The steel leaf spring 11 is connected to the permanent magnet mounting frame 8 through the middle pressure block 12, and the steel leaf spring 11 is connected to the mounting frame 10 through the pressure blocks 13 at both ends. The steel leaf spring 11 will limit the position of the permanent magnet array. When the position of the permanent magnet array is offset from the magnetic core 1 and is subjected to the adsorption force of the magnetic core 1, the restoring force provided by the steel leaf spring 11 needs to be greater than the adsorption force of the magnetic core 1 to maintain the position of the permanent magnet array in the magnetic gap.

[0035] like Figure 5 and Figure 6As shown, the above structure constitutes a single moving magnetic sub-drive stack. When assembling, the mounting frame 10 is taken as the center. First, the bonded permanent magnet array and permanent magnet mounting frame 8 are placed in the middle of the mounting frame 10, and then the permanent magnet mounting frame 8 is assembled with the steel leaf spring 11 and the middle pressure block 12, and then the two ends of the steel leaf spring 11 are assembled with the mounting frame 10 and the pressure blocks 13 at both ends. At this time, the permanent magnet mounting frame 8 is fixed on the mounting frame 10, the coil skeleton 6 is sleeved on the magnetic core 1, and fixed with epoxy bonding, and then two magnetic cores 1 are installed from the upper and lower parts of the mounting frame 10, and the magnetic core 1 is fixed to the mounting frame 10 with a crossbeam 14. At this point, a single moving magnetic sub-drive stack is installed.

[0036] like Figure 7 and Figure 8 As shown, the two single-moving magnetic sub-drive stacks are longitudinally connected by a connecting seat 15, and two support plates 20 are provided on the top surface of the upper single-moving magnetic sub-drive stack and the bottom surface of the lower single-moving magnetic sub-drive stack. Both sides of the permanent magnetic mounting frames 8 of the two single-moving magnetic sub-drive stacks are connected to radiation surface bases 16, and the support plates 20 are connected to the radiation surface bases 16 through coil springs 17. In order to ensure that the output forces of the two single-moving magnetic sub-drive stacks are in the same direction, the two single-moving magnetic sub-drive stacks are connected in parallel in the circuit. When connecting the cables, it is necessary to ensure that the circuits are connected in parallel.

[0037] The two ends of the coil spring 17 are respectively screwed and connected with the front connection seat 18 and the rear connection seat 19, the front connection seat 18 is connected to the radiation surface base 16, and the rear connection seat 19 is connected to the support plate 20. The coil spring 17 is designed according to the operating frequency of the transducer. In order to facilitate the installation of the coil spring 17, the front connection seat 18 and the rear connection seat 19 are designed at both ends of the coil spring 17. One end of the front connection seat 18 and the rear connection seat 19 can be screwed with the coil spring 17, and the other end is designed as a screw to connect with other parts.

[0038] The connection base 15 is connected to the mounting frame 10, and the support plate 20 is connected to the mounting frame 10. The connection base 15 is used to fix and connect two single-moving magnetic sub-drive stacks, the coil spring 17 is used to provide stiffness for the vibration system, and the support plate 20 is used to connect the coil spring 17 and the mounting frame 10. When used as a transducer driving source, the support plate 20 can be connected to the transducer housing.

[0039] The radiation surface base 16 is used to connect the coil spring 17 and the radiation surface of the transducer. The radiation surface base 16 is connected to the coil spring 17 and the permanent magnet mounting frame 8. The combined force of the two single moving magnetic sub-drive stacks acts on the radiation surface base 16. When used as a transducer driving source, the radiation surface can be installed at the other end of the radiation surface base 16.

[0040] The working principle of the present invention is: Figure 1Based on the moving magnetic drive magnetic circuit shown, when the double moving magnetic drive stack is working, alternating current is passed through the coil 2, generating an alternating magnetic field that interacts with the magnetic field of the permanent magnet array, generating a lateral force that causes the permanent magnet array to move laterally, and then transmitted to the radiation surface base 16 through the permanent magnet mounting frame 8 to drive the radiation surface connected to the radiation surface base 16 to vibrate.

[0041] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. According to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
