Description

Technical Field

[0001] The present invention relates to the technical field of switching power supplies, and specifically to a multi-module high-efficiency, stable, and high-voltage switching power supply. Background Art

[0002] With the continuous progress of power electronics technology, switching power supply technology has been continuously developing. High-voltage switching power supplies are widely used in fields such as high-voltage test instruments, medical equipment, new energy, and scientific research experiments, and the performance requirements for high-voltage switching power supplies have also increased accordingly. However, during the transportation of high-voltage switching power supplies or when high-voltage switching power supplies are in an environment with a lot of dust, impurities such as dust and particulate matter in the air will enter the power supply interior through openings such as heat dissipation holes, causing the power supply to malfunction during use or its heat dissipation effect to decline.

[0003] Traditional high-voltage switching power supplies lack necessary dust-proof protection mechanisms, allowing impurities such as dust in the air to accumulate on the heat dissipation holes and enter the power supply interior, resulting in malfunctions after the high-voltage switching power supply is started. At the same time, dust will hinder the dissipation of heat, causing the temperature inside the power supply to rise and reducing the working efficiency of the power supply. Therefore, a multi-module high-efficiency, stable, and high-voltage switching power supply is extremely important.

The above patent realizes the phase-shifted pulse width modulation closed-loop soft-switching voltage stabilization control of the power supply, but the above patent cannot achieve the dust-proof function when the high-voltage switching power supply is not in use.

The above patent realizes the operation of the high-voltage switch outside a safe range of 30 - 50 meters from the high-voltage switch, greatly improving the safety of operators, but the above patent cannot perform the fixing function of the dust-proof cloth for the high-voltage switching power supply.

[0006] 3. Patent document CN108666979B discloses a real-time protection circuit for a high-voltage switching power supply. The above patent realizes the control of the charging time of the filter energy storage circuit and timely cuts off the input high voltage in case of abnormal situations, but the above patent cannot perform the dust removal function when the high-voltage switching power supply is in use.

[0007] 4. Patent document CN115441314B discloses a high-voltage complete switchgear with good electromagnetic compatibility. The above patent realizes that the high-voltage complete switchgear has good sealing and improves the function of electromagnetic compatibility, but the above patent cannot achieve the dust collection function when the high-voltage switching power supply is in use.

[0008] In summary, the above-mentioned patent cannot achieve the dust-proof function when the high-voltage switching power supply is not in use, cannot achieve the fixing function of the dust-proof cloth of the high-voltage switching power supply, cannot achieve the dust-removing function when the high-voltage switching power supply is in use, and cannot achieve the dust collection function when the high-voltage switching power supply is in use, resulting in problems such as dust entering the high-voltage switching power supply and affecting its heat dissipation, and external forces affecting the dust-proof effect; Therefore, the present application proposes a multi-module high-efficiency and stable high-voltage switching power supply that realizes the dust-proof function when the high-voltage switching power supply is not in use, realizes the fixing function of the dust-proof cloth of the high-voltage switching power supply, realizes the dust-removing function when the high-voltage switching power supply is in use, and realizes the dust collection function when the high-voltage switching power supply is in use.

[0026] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 , an embodiment provided by the present invention: a multi-module high-efficiency and stable high-voltage switching power supply, including a power supply main body 1, a protective shell 2 and a dust-proof module. The protective shell 2 is fixedly installed on the outer wall of the power supply main body 1, and the dust-proof module is installed on the protective shell 2. The dust-proof module is used to prevent dust from entering the power supply main body 1 through the protective shell 2; the dust-proof module includes: a first rotating rod 5, a rotating roller 7, a dust-proof cloth 8 and a first rotating block 10; the outer wall of the protective shell 2 is symmetrically and fixedly connected with fixing blocks 4, the outer wall of the fixing blocks 4 is symmetrically and fixedly connected with side plates 3, the side walls of the side plates 3 are fixedly connected with the protective shell 2, the bottom of the outer wall of the side plates 3 is fixedly connected with a first connecting block 27, the side plates 3 are movably sleeved on the outer wall of the first rotating rod 5, the outer wall of the first rotating rod 5 is fixedly sleeved with a rotating roller 7, the outer wall of the rotating roller 7 is fixedly connected with a dust-proof cloth 8, the dust-proof cloth 8 is wound around the outer wall of the rotating roller 7, a first opening groove 6 is opened in the side plates 3, both ends of the rotating roller 7 and the dust-proof cloth 8 are located in the first opening groove 6, heat dissipation grooves 52 are symmetrically opened on the outer wall of the protective shell 2, the outer wall of the first rotating rod 5 is movably sleeved with a first rotating block 10, and the bottom of the outer wall of the dust-proof cloth 8 is fixedly connected with a baffle 16; A fixing module is installed on the first connecting block 27, and the fixing module is used for clamping and fixing the dust-proof cloth 8; the fixing module is selected from a clamping mechanism and a clamping and engaging mechanism. The clamping mechanism includes: a fixing frame 29, a second spring 30, a first clamping plate 31, a second clamping plate 32, and a rotating shaft 33; the bottom of the side wall of the first connecting block 27 is fixedly connected with a protective shell 2, the first connecting block 27 is movably sleeved on the outer wall of the sliding block 28, the sliding block 28 is movably sleeved on the outer wall of the rotating block 34, the outer wall of the rotating block 34 is movably sleeved on the outer wall of the fixing frame 29, the side wall of the fixing frame 29 is fixedly connected with a second spring 30, the side wall of the second spring 30 is fixedly connected with a first clamping plate 31, the fixing frame 29 is movably sleeved on the outer wall of the rotating shaft 33, the thread of the fixing frame 29 matches the thread of the rotating shaft 33, the outer wall of the rotating shaft 33 is movably sleeved with a second clamping plate 32, the top of the inner wall of the first connecting block 27 is fixedly connected with a limiting block 35, a limiting groove 36 is opened at the top of the outer wall of the sliding block 28, the limiting groove 36 is movably sleeved on the outer wall of the limiting block 35, the bottom of the sliding block 28 is fixedly connected with a moving toothed plate 37, the first connecting block 27 is movably sleeved on the outer wall of the rotating shaft 38, a rotating gear 39 is fixedly sleeved on the outer wall of the rotating shaft 38, the rotating gear 39 meshes with the moving toothed plate 37, a hollow groove 62 is opened in the sliding block 28, the rotating gear 39 is located in the hollow groove 62, and a second rotating block 61 is fixedly connected to the side wall of the rotating shaft 38.

[0027] Further, when the power supply main body 1 is not running, the user can rotate the first rotating block 10 on the side plate 3. The first rotating block 10 drives the first rotating rod 5 to rotate. The first rotating rod 5 drives the rotating roller 7 to rotate in the first opening groove 6. The rotating roller 7 drives the dust-proof cloth 8 to rotate, so as to unfold the dust-proof cloth 8 wound on the rotating roller 7. The dust-proof cloth 8 moves in the first opening groove 6. The dust-proof cloth 8 drives the baffle 16 to move downward, so that the dust-proof cloth 8 is completely unfolded, so that the dust-proof cloth 8 shields the heat dissipation groove 52, preventing external dust from floating into the protective shell 2 through the heat dissipation groove 52, and preventing dust from accumulating on the power supply main body 1, resulting in poor heat dissipation when using the power supply main body 1. The fixing block 4 protects the rotating roller 7 and the dust-proof cloth 8, avoiding the collision of external forces on the rotating roller 7 and the dust-proof cloth 8, and at the same time preventing dust from accumulating on the dust-proof cloth 8, resulting in the scattering of dust when the dust-proof cloth 8 is unfolded, so that dust passes through the heat dissipation groove 52, reducing equipment failures caused by dust accumulation, thereby reducing the maintenance cost and repair frequency of the equipment. The dust-proof cloth 8 shields the heat dissipation groove 52 when the power supply is not in use. When the equipment is running, the dust-proof cloth 8 can be rolled up to ensure unobstructed heat dissipation in the groove 52, thereby improving the heat dissipation efficiency of the power supply main body 1 and ensuring the stable operation of the power supply main body 1; After the dust-proof cloth 8 is unfolded, rotate the second rotating block 61. The second rotating block 61 drives the rotating shaft 38 to rotate. The rotating shaft 38 drives the rotating gear 39 to rotate within the hollow groove 62. The rotating gear 39 drives the moving toothed plate 37 to move. The moving toothed plate 37 drives the sliding block 28 to move. The sliding block 28 drives the rotating block 34 and the fixing bracket 29 to move, so that the fixing bracket 29 gradually approaches the dust-proof cloth 8. Rotate the fixing bracket 29. The fixing bracket 29 drives the second spring 30, the first clamping plate 31, the rotating shaft 33, and the second clamping plate 32, so that the dust-proof cloth 8 is located between the first clamping plate 31 and the second clamping plate 32. Rotate the rotating shaft 33. The rotating shaft 33 drives the second clamping plate 32, so that the second clamping plate 32 gradually approaches the first clamping plate 31, and the dust-proof cloth 8 gradually comes into contact with the first clamping plate 31 and the second clamping plate 32. The second clamping plate 32 drives the dust-proof cloth 8 and the first clamping plate 31 to gradually compress the second spring 30. Under the action of the elastic force of the second spring 30, the dust-proof cloth 8 is in close contact with the first clamping plate 31 and the second clamping plate 32, realizing the fixation of the dust-proof cloth 8 by the first clamping plate 31 and the second clamping plate 32. Thus, it is avoided that the dust-proof cloth 8 is displaced due to external force, resulting in the dust-proof cloth 8 being unable to completely cover the heat dissipation slot 52, causing dust to enter the protective shell 2 and affecting the stability of the power supply main body 1 during use. By stably maintaining the dust-proof cloth 8 in the shielding position, the dust-proof cloth 8 is not easily blown by the wind or accidentally displaced, ensuring the durability of the dust-proof effect and solving the problem that the dust-proof cloth 8 is prone to displacement due to lack of fixation.

[0028] Please refer to Figure 1 , Figure 3 and Figure 6, an embodiment provided by the present invention: a multi-module high-efficiency and stable high-voltage switching power supply. Fixed blocks 4 are symmetrically and fixedly connected to the outer wall of the protective shell 2. Side plates 3 are symmetrically and fixedly connected to the outer wall of the fixed blocks 4. The side plates 3 are fixedly connected to the side wall of the protective shell 2. A first connecting block 27 is fixedly connected to the bottom of the outer wall of the side plate 3. The side plate 3 is movably sleeved on the outer wall of the first rotating rod 5. A rotating roller 7 is fixedly sleeved on the outer wall of the first rotating rod 5. A dust-proof cloth 8 is fixedly connected to the outer wall of the rotating roller 7. The dust-proof cloth 8 is wound around the outer wall of the rotating roller 7. A first opening groove 6 is formed in the side plate 3. Both ends of the rotating roller 7 and the dust-proof cloth 8 are located in the first opening groove 6. Heat dissipation grooves 52 are symmetrically formed in the outer wall of the protective shell 2. A first rotating block 10 is movably sleeved on the outer wall of the first rotating rod 5. A baffle 16 is fixedly connected to the bottom of the outer wall of the dust-proof cloth 8; A fixing module is installed on the first connecting block 27. The fixing module is selected from one of a clamping mechanism and a clamping and engaging mechanism. The clamping and engaging mechanism includes: a first clamping block 40, a second clamping block 41, a second connecting block 42, a connecting rod 43, a third spring 44 and a connecting plate 46; A first clamping block 40 is fixedly connected to the side wall of the first connecting block 27. Connecting rods 43 are symmetrically and fixedly sleeved on the outer wall of the first connecting block 27. A second connecting block 42 is movably sleeved on the outer wall of the connecting rod 43. A second clamping block 41 is fixedly connected to the side wall of the second connecting block 42. A connecting plate 46 is movably sleeved on the outer wall of the connecting rod 43. A third spring 44 is fixedly connected to the side wall of the connecting plate 46. The side wall of the third spring 44 is fixedly connected to the second connecting block 42. The third spring 44 is movably sleeved on the outer wall of the connecting rod 43. A third rotating block 45 is movably sleeved on the outer wall of the connecting rod 43. The thread of the connecting rod 43 matches the thread of the third rotating block 45.

[0029] Further, rotate the first rotating block 10. The first rotating block 10 drives the first rotating rod 5 and the rotating roller 7. The rotating roller 7 drives the dust-proof cloth 8 to unfold the dust-proof cloth 8 to shield the heat dissipation slots 52 and prevent dust from passing through the heat dissipation slots 52. The dust-proof cloth 8 drives the baffle 16 to move downward. When the baffle 16 moves above the first engaging block 40 and the second engaging block 41 and cannot move further, continue to rotate the first rotating block 10 to make the dust-proof cloth 8 unfold a further distance. Then press the baffle 16. The baffle 16 contacts the inclined surfaces on the first engaging block 40 and the second engaging block 41, causing the baffle 16 to squeeze the first engaging block 40. Thereby, the baffle 16 drives the first engaging block 40 to move. The first engaging block 40 drives the second connecting block 42 to compress the third spring 44. The second connecting block 42 moves on the connecting rod 43. When the baffle 16 moves downward to the middle position between the first engaging block 40 and the second engaging block 41, the baffle 16 no longer squeezes the first engaging block 40. The third spring 44 returns from the compressed state to the original state. The third spring 44 drives the second connecting block 42. The second connecting block 42 drives the second engaging block 41 to approach the first engaging block 40 and fit with the baffle 16. Since the shapes of the first engaging block 40 and the second engaging block 41 are the same as the shape of the baffle 16, the first engaging block 40 and the second engaging block 41 are sleeved on the outer wall of the baffle 16 to fix the baffle 16, and further fix the dust-proof cloth 8. By rotating the third rotating block 45, the third rotating block 45 moves on the connecting rod 43. The third rotating block 45 drives the connecting plate 46 to compress the third spring 44. Thereby, the elastic force exerted by the third spring 44 on the second connecting block 42 is increased, the pressure exerted by the second connecting block 42 on the second engaging block 41 is increased, and the fixation of the second engaging block 41 and the first engaging block 40 on the baffle 16 is more stable. Compared with the clamping mechanism, the engaging mechanism fixes the dust-proof cloth 8 by fixing the baffle 16, avoiding direct contact with the dust-proof cloth 8, which may cause excessive clamping force of the fixing module and damage the dust-proof cloth 8.

[0030] Please refer to Figure 1 and Figure 2 As shown in and, an embodiment provided by the present invention is a multi-module high-efficiency and stable high-voltage switching power supply, including a power supply main body 1, a protective shell 2, and a dust-proof module. The protective shell 2 is fixedly installed on the outer wall of the power supply main body 1. The protective shell 2 is provided with a dust-proof module for preventing dust from entering the power supply main body 1 through the protective shell 2. The dust-proof module includes a first rotating rod 5, a rotating roller 7, a dust-proof cloth 8, and a first rotating block 10. A pushing block 9 is fixedly connected to the side wall of the first rotating rod 5. First springs 11 are symmetrically and fixedly connected to the outer wall of the pushing block 9. The first rotating block 10 is movably sleeved on the outer wall of the pushing block 9. The first springs 11 are fixedly connected to the inner wall of the first rotating block 10. First positioning blocks 12 are equidistantly and fixedly connected to the outer wall of the first rotating block 10. First positioning grooves 13 are equidistantly formed in the outer wall of the side plate 3. The first positioning grooves 13 are movably sleeved on the outer wall of the first positioning blocks 12.

[0031] Further, before rotating the first rotating block 10, the user first pulls the first rotating block 10. The first rotating block 10 compresses the first spring 11, and the first rotating block 10 drives the first positioning block 12 to leave the first positioning groove 13 on the side plate 3. Then, the first rotating block 10 is rotated. The first rotating block 10 drives the pushing block 9 to rotate, the pushing block 9 drives the first rotating rod 5 to rotate, the first rotating rod 5 drives the rotating roller 7 to rotate, and the rotating roller 7 drives the dust-proof cloth 8, so as to unfold the dust-proof cloth 8. When the unfolding of the dust-proof cloth 8 is completed, the first rotating block 10 is no longer pulled, and the first rotating block 10 is slightly rotated. When the first positioning block 12 on the first rotating block 10 is aligned with the first positioning groove 13, the first spring 11 returns from the compressed state to the original state. The first spring 11 elastically pushes the first rotating block 10, and the first rotating block 10 drives the first positioning block 12 to move into the first positioning groove 13. The user observes that the first rotating block 10 moves closer to the side plate 3 and no longer applies an external force to the first rotating block 10, thereby realizing the unfolding of the dust-proof cloth 8. By fixing the first positioning block 12 through the first positioning groove 13, it is avoided that the user accidentally touches the first rotating block 10 and causes it to rotate, resulting in the displacement of the dust-proof cloth 8. During the use of the device, the displacement of the dust-proof cloth 8 will cause the dust-proof cloth 8 to unfold and affect the heat dissipation of the power supply main body 1; when the device is in the working state, the displacement of the dust-proof cloth 8 will cause the dust-proof cloth 8 to unfold incompletely and lose the function of blocking dust.

[0032] Please refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 7, an embodiment provided by the present invention: a multi-module high-efficiency and stable high-voltage switching power supply, including a power supply main body 1, a protective shell 2 and modules. A protective shell 2 is fixedly installed on the outer wall of the power supply main body 1. A dust-proof module is installed on the protective shell 2. The dust-proof module includes: a first rotating rod 5, a rotating roller 7, a dust-proof cloth 8 and a first rotating block 10. Heat dissipation grooves 52 are symmetrically opened on the outer wall of the protective shell 2; a fixing module is installed on the first connecting block 27, and the fixing module is used for clamping and fixing the dust-proof cloth 8; a second opening groove 15 is opened on the side wall of the side plate 3, the first opening groove 6 communicates with the second opening groove 15, the second opening groove 15 is movably sleeved on the outer wall of the moving rod 17, the side wall of the moving rod 17 is fixedly connected to the outer wall of the moving frame 18, a third opening groove 22 is opened in the moving frame 18, the third opening groove 22 is movably sleeved on the outer wall of the dust-proof cloth 8, the moving frame 18 is movably sleeved on the outer wall of the first mounting block 19, symmetrically fixed connections are provided on the outer wall of the first mounting block 19 with first compression springs 21, the side walls of the first compression springs 21 are fixedly connected to the moving frame 18, the first mounting block 19 is connected by a rotating shaft to a first dust removal roller 20; a second mounting block 23 is fixedly connected to the side wall of the moving frame 18, the second mounting block 23 is movably sleeved on the outer wall of the first push plate 25, the side wall of the first push plate 25 is fixedly connected to a second compression spring 24, the side wall of the second compression spring 24 is fixedly connected to the moving frame 18, a dust removal brush 26 is fixedly connected to the side wall of the first push plate 25, and the outer wall of the dust removal brush 26 is movably sleeved on the second mounting block 23.

[0033] Further, after the dust-proof cloth 8 wound around the rotating roller 7 is unfolded and fixed, the moving rod 17 is pulled. The moving rod 17 moves within the second opening groove 15. The moving rod 17 drives the moving frame 18 to move. The moving frame 18 drives the first compression spring 21, the first mounting block 19 and the first dust removal roller 20 to move. The first compression spring 21 presses against the first mounting block 19, causing the first mounting block 19 to drive the first dust removal roller 20 to be in close contact with the dust-proof cloth 8. By sliding the moving rod 17 up and down, the first dust removal roller 20 moves up and down on the dust-proof cloth 8, thereby cleaning the dust on the surface of the dust-proof cloth 8. If the dust-proof cloth 8 shields the protective shell 2 for a long time, a large amount of dust will accumulate on the surface of the dust-proof cloth 8, causing dust to scatter when the dust-proof cloth 8 is wound, and then entering the protective shell 2. By regularly sliding the moving rod 17, the first dust removal roller 20 regularly cleans the surface of the dust-proof cloth 8 to avoid dust accumulation. At the same time, after the equipment works for a period of time, dust will accumulate on the heat dissipation grooves 52 on the outer surface of the protective shell 2. After the dust-proof cloth 8 is unfolded and fixed, during the regular cleaning of the dust-proof cloth 8, the up and down movement of the moving frame 18 will drive the second mounting block 23. The second mounting block 23 drives the first push plate 25 and the dust removal brush 26. The second compression spring 24 elastically pushes the first push plate 25 and the dust removal brush 26, causing the dust removal brush 26 to contact the protective shell 2. The up and down movement of the dust removal brush 26 will clean the heat dissipation grooves 52 on the outer surface of the protective shell 2, thereby avoiding dust accumulation in the heat dissipation grooves 52 and affecting the heat dissipation of the power supply main body 1 during the use of the equipment.
