Description

Technical Field

[0001] The present invention relates to the technical field of permanent magnet eddy current speed regulators, in particular to a circulating liquid-cooled high-power permanent magnet eddy current speed regulator. Background Art

[0002] When a permanent magnet eddy current speed controller operates at high speed for extended periods, the internal conductor disk generates a significant amount of heat due to the eddy current effect. If this heat is not promptly dissipated, the conductor disk will be exposed to high-temperature radiation for extended periods, leading to demagnetization and failure, affecting the stable operation of the permanent magnet eddy current speed controller. Therefore, high-power permanent magnet eddy current speed controllers must be equipped with a heat dissipation mechanism.

[0003] In the prior art, heat dissipation mechanisms and methods used in high-power permanent magnet speed regulators mainly include: 1. Installing aluminum alloy heat sinks on the high-power permanent magnet speed regulator and dissipating heat by spraying cooling water inside the high-power permanent magnet speed regulator. However, this method can easily cause rust and damage to the internal components of the high-power permanent magnet speed regulator, and sealing the cooling water is also difficult to achieve. 2. Placing the conductor assembly and permanent magnet assembly of the high-power permanent magnet speed regulator in a sealed box, and installing a heat dissipation liquid box on the conductor disk of the conductor assembly. The heat dissipation liquid box is provided with 20-50 liquid distribution holes. The heat dissipation medium in the heat dissipation liquid box evaporates and removes heat from the conductor disk. However, this method has low heat dissipation efficiency, complex heat dissipation mechanism structure, and high maintenance costs. 3. Arranging coolant channels in the high-power permanent magnet speed regulator's casing to cool the high-power permanent magnet speed regulator with coolant. However, this heat dissipation mechanism mainly cools the casing and has poor heat dissipation effect on the conductor disk. 4. The high-power permanent magnet speed regulator has a unidirectional heat dissipation mechanism, which only allows the cooling medium to flow in one direction, resulting in limited heat dissipation capacity.

[0050] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0051] See also Figure 1-10 As shown, the circulating liquid-cooled high-power permanent magnet eddy current speed regulator proposed in an embodiment of the present invention includes two oppositely arranged housings 1, two oppositely arranged conductor disk backplates 2, and two oppositely arranged conductor disks 3. The two conductor disk backplates 2 are respectively fixed to opposite sides of the two housings 1, and the two conductor disks 3 are respectively fixed to opposite sides of the two conductor disk backplates 2. Each conductor disk backplate 2 is provided with a liquid storage groove 21 at one end surface. The liquid storage groove 21 covers the entire conductor disk backplate 2 and is used to hold the refrigerant liquid. Each housing 1 is provided with a liquid inlet channel 13 and a liquid discharge channel 14. Along the flow direction of the refrigerant liquid, the liquid inlet channel 13, the liquid storage groove 21, and the liquid discharge channel 14 are connected in sequence.

[0052] During use, refrigerant liquid is introduced into the liquid tank 21 of the conductor disk back plate 2 through the liquid inlet channel 13 of the housing 1. The refrigerant liquid flows along the liquid tank 21 over the entire conductor disk back plate 2 to absorb heat from the entire conductor disk back plate 2, thereby improving the heat dissipation efficiency and effect of the conductor disk back plate 2. Furthermore, after absorbing heat, the refrigerant liquid in the liquid tank 21 is discharged through the liquid discharge channel 14 to achieve circulating refrigeration. Because the refrigerant liquid is sealed between the conductor disk back plate 2 and the housing 1, or between the conductor disk back plate 2 and the conductor disk 3, rust caused by the refrigerant liquid contacting the internal structure of the circulating liquid-cooled high-power permanent magnet eddy current speed regulator is avoided.

[0053] Furthermore, each conductor disk back plate 2 is provided with a back plate liquid inlet hole 23 and a back plate liquid drain hole 24. Along the flow direction of the refrigerant liquid, the liquid inlet channel 13, the back plate liquid inlet hole 23, the liquid receiving tank 21, the back plate liquid drain hole 24, and the liquid drain channel 14 are sequentially connected. Preferably, the back plate liquid inlet hole 23 and the back plate liquid drain hole 24 are located on the same circumference of the conductor disk back plate 2.

[0054] Furthermore, the liquid trough 21 is located on an end surface of the conductor disk back plate 2 close to the shell 1, or the liquid trough 21 is located on an end surface of the conductor disk back plate 2 close to the conductor disk 3, preferably arranged to be located on an end surface of the conductor disk back plate 2 close to the conductor disk 3 to improve the cooling effect on the conductor disk 3.

[0055] Furthermore, the liquid containing tank 21 includes a plurality of liquid containing branches that are connected in sequence. Along the flow direction of the refrigerant liquid, the plurality of liquid containing branches are sequentially arranged on the conductor disk 3 from the inside to the outside.

[0056] Figure 5 The arrow in the middle indicates the flow direction of the refrigerant. Water flows sequentially through the backplate inlet 23, multiple water-receiving branches, and the backplate drain 24, evenly distributing the refrigerant throughout the conductor disk backplate 2. The conductor disk backplate 2 then transfers the cooling energy of the refrigerant to the conductor disk 3. This allows for continuous injection and discharge of refrigerant, improving the cooling efficiency of the conductor disk 3.

[0057] Furthermore, each housing 1 includes a housing body 11 and an extension portion 12 . The extension portion 12 is provided on opposite sides of each housing body 11 along its axial direction. The liquid inlet channel 13 and the liquid discharge channel 14 both connect the extension portion 12 and the housing body 11 .

[0058] Furthermore, the extension portion 12 is sleeved on the outside of the input shaft 81 and is fixed to the input shaft 81 by bolts or welded, or the housing 1 and the input shaft 81 are integrally formed. The housing 1, the conductor disc back plate 2, the conductor disc 3 and the input shaft 81 can rotate synchronously.

[0059] Furthermore, the circulating liquid-cooled high-power permanent magnet eddy current governor also includes two sealing assemblies 5, which are respectively mounted on the two extensions 12. The sealing assemblies 5 can rotate synchronously with the housing 1 and can seal the liquid inlet line 71, the liquid inlet channel 13, the liquid discharge channel 14, and the liquid discharge line 72.

[0060] Specifically, the sealing assembly 5 includes a first sealing structure, specifically including: an outer sealing ring 51 and an inner sealing ring 52. The outer sealing ring 51 and the extension part 12 are connected through a bearing 82. The outer sealing ring 51 is sleeved on the outside of the inner sealing ring 52. The inner sealing ring 52 is sleeved on the outside of the extension part 12. There is a gap between the outer sealing ring 51 and the inner sealing ring 52.

[0061] Both the outer sealing ring 51 and the inner sealing ring 52 are provided with a communicating sealed liquid inlet hole 53 and a communicating sealed liquid drain hole 54. The sealed liquid inlet hole 53 accommodates one end of the liquid inlet line 71 and communicates with the liquid inlet channel 13. The sealed liquid drain hole 54 accommodates one end of the liquid drain line 72 and communicates with the liquid drain channel 14. Due to the gap between the outer sealing ring 51 and the inner sealing ring 52, under the action of the high pressure during the discharge of the refrigerant liquid, the refrigerant liquid leaking from the liquid inlet line 71, the liquid inlet channel 13, the liquid drain channel 14, or the liquid drain line 72 is squeezed and accumulated in the gap between the outer sealing ring 51 and the inner sealing ring 52, forming a liquid seal for the gap between the outer sealing ring 51 and the inner sealing ring 52, thereby achieving a sealing effect on the liquid inlet line 71, the liquid inlet channel 13, the liquid drain channel 14, and the liquid drain line 72.

[0062] Preferably, to improve the sealing performance of the sealing assembly 5, the sealing assembly 5 further includes a second sealing structure, which is a labyrinth-type structure. Specifically, the inner circumferential sidewall of the outer sealing ring 51 is provided with two outer protrusions 511 extending radially therefrom. The two outer protrusions 511 are respectively located at both ends of the sealed liquid inlet hole 53 and / or the sealed liquid discharge hole 54. A gap exists between the outer protrusions 511 and the inner sealing ring 52, and a first outer groove 512 is provided on the inner circumferential sidewall of the outer protrusion 511. The outer circumferential sidewall of the inner sealing ring 52 is provided with two inner protrusions 521 extending radially therefrom. The two inner protrusions 521 and the two first outer grooves 512 are provided in a one-to-one correspondence. Each inner protrusion 521 is located within a corresponding first outer groove 512, and a gap exists between the inner protrusion 521 and the first outer groove 512.

[0063] When the refrigerant liquid flows out of the gap between the outer sealing ring 51 and the inner sealing ring 52, this part of the refrigerant liquid continues to flow into the gap between the outer protrusion 511 and the inner sealing ring 52 and into the gap between the inner protrusion 521 and the first outer groove 512, and is squeezed and accumulated in the above two gaps, further forming a sealing effect on the gap between the outer protrusion 511 and the inner sealing ring 52 and the gap between the sealing ring and the inner sealing ring 52, thereby improving the sealing safety of the sealing assembly 5 for the refrigerant liquid.

[0064] More preferably, the sealing assembly 5 further includes a third sealing structure, specifically, a second outer groove 513 is provided on the inner circumferential sidewall of the outer protrusion 511. When some refrigerant liquid continues to flow into the gap between the outer protrusion 511 and the inner sealing ring 52, and into the gap between the inner protrusion 521 and the first outer groove 512, the second outer groove 513 can also accommodate some of the refrigerant liquid. This portion of refrigerant liquid is squeezed and accumulated within the second outer groove 513, thereby improving the sealing and sealing safety of the sealing assembly 5. Preferably, the second outer groove 513 is an arc-shaped groove. Of course, other shapes of the second outer groove 513 can also be used as long as they can accommodate the refrigerant liquid. Preferably, a third outer groove 514 is provided at the bottom of the second outer groove 513. This third outer groove 514 can also accommodate some of the refrigerant liquid. This portion of refrigerant liquid is squeezed and accumulated within the third outer groove 514, further improving the sealing and sealing safety of the sealing assembly 5.

[0065] More preferably, the sealing assembly 5 further includes a fourth sealing structure, specifically, two end sealing rings. Both end sealing rings are sleeved on the extension portion 12, with one end sealing ring located between the end of the outer sealing ring 51 proximal to the housing body 11 and the housing body 11, and the other end sealing ring located between the end of the outer sealing ring 51 distal to the housing body 11 and the bearing 82. The two end sealing rings are located at both ends of the first-third sealing structure, thereby sealing the refrigerant liquid that has escaped from the first-third sealing structure, thereby improving the sealing and sealing safety of the sealing assembly 5. The end sealing rings are preferably lip-shaped sealing rings.

[0066] Furthermore, the circulating liquid-cooled high-power permanent magnet eddy current speed regulator also includes a liquid supply and discharge component 6, which is used to introduce refrigerant liquid into the liquid tank 21, and to recover the refrigerant liquid in the liquid tank 21 and cool the refrigerant liquid to achieve circulating refrigeration of the conductor disk 3 by the refrigerant liquid, thereby improving the utilization rate of the refrigerant liquid.

[0067] Specifically, the drain hole of the liquid supply and drainage assembly 6 is connected to the liquid inlet channel 13 via the liquid inlet pipe 71, and the liquid supply and drainage assembly 6 discharges liquid into the liquid inlet channel 13. The return hole of the liquid supply and drainage assembly 6 is connected to the liquid discharge channel 14 via the liquid discharge pipe 72, and the liquid discharge channel 14 discharges liquid into the liquid supply and drainage assembly 6, so that the liquid supply and drainage assembly 6 can cool the refrigerant liquid.

[0068] Furthermore, along the flow direction of the refrigerant liquid, the liquid supply and discharge assembly 6 includes, in sequence, a radiator 61, a water pump 62, and a valve 63. One end of the radiator 61 is connected to a liquid discharge line 72, and the other end is connected to a liquid inlet line 71. The water pump 62 and valve 63 are both located on the liquid inlet line 71. The radiator 61 is used to cool the refrigerant liquid discharged from the liquid tank 21 on the conductor disk back plate 2 and circulate the cooled refrigerant liquid back into the liquid tank 21 on the conductor disk back plate 2, thereby improving the utilization rate of the refrigerant liquid. The valve 63 is used to open or close the liquid inlet line 71 that discharges the refrigerant liquid into the liquid tank 21. The water pump 62 is used to discharge the refrigerant liquid into the liquid tank 21. The radiator 61 is preferably a convection radiator.

[0069] Furthermore, the circulating liquid-cooled high-power permanent magnet eddy current speed regulator includes two opposing magnetic steel disks 4, which are located between the two conductor disks 3. A plurality of magnetic steel blocks 41 are arranged at intervals along the circumference of the magnetic steel disks 4. Adjacent magnetic steel blocks 41 have opposite magnetic properties, and an even number of magnetic steel blocks 41 is preferably provided.

[0070] Furthermore, a distance adjustment component is provided on the opposite side of the two magnetic steel disks 4. The distance adjustment component can adjust the distance between the two magnetic steel disks 4, and thereby change the size of the air gap between the magnetic steel disk 4 and the corresponding conductor disk 3, and then adjust the rotation speed of the conductor disk 3, the conductor disk back plate 2, the shell 1 and the input shaft 81, thereby realizing stepless speed regulation of the input shaft 81. Moreover, the contactless speed regulation method between the conductor disk 3 and the magnetic steel disk 4 avoids friction loss between the conductor disk 3 and the magnetic steel disk 4, thereby extending the service life of the circulating liquid-cooled high-power permanent magnet eddy current speed regulator, and can also avoid the phenomenon that the speed regulation mechanism is easily damaged due to the impact current of the motor when other speed regulation mechanisms are used.

[0071] Specifically, the distance adjustment assembly includes a scissor-type support arm 91, which is hinged on opposite sides of the two magnetic disks 4. Preferably, the branches of the scissor-type support arm 91 are connected by an electric telescopic rod 92, which is used to drive the opening and closing angles of the scissor-type support arm 91, thereby adjusting the distance between the two magnetic disks 4.

[0072] Perhaps, pitch-adjusting assembly comprises screw rod 93, nut sleeve 94 and motor 95, and nut sleeve 94 is sleeved on the periphery of screw rod 93, and nut sleeve 94 and screw rod 93 are threadedly connected, and nut sleeve 94 or screw rod 93 are connected with the driving end of motor 95 respectively.When nut sleeve 94 was connected with the driving end of motor 95, motor 95 drove nut sleeve 94 to rotate around screw rod 93, with the spacing of correspondingly adjusting two magnetic steel disks 4.When screw rod 93 was connected with the driving end of motor 95, motor 95 drove screw rod 93 to rotate around nut sleeve 94, with the spacing of correspondingly adjusting two magnetic steel disks 4.

[0073] Of course, other distance adjustment components that can linearly adjust the distance between the two magnetic steel disks 4 are used.
