Description

Technical Field

[0001] The utility model relates to the technical field of high - voltage drive power supplies, in particular to a high - voltage drive power supply with a dust - proof structure. Background Technique

[0002] A high - voltage drive power supply generally refers to a power supply that outputs a high - voltage direct current, and its output voltage can generally reach several thousand volts to several million volts. High - voltage power supplies play a crucial role in industrial production and scientific research. For example, particle accelerators, X - ray generators, etc. all need to use high - voltage power supplies. A high - voltage power supply usually consists of a transformer, a rectifier, a filter, a voltage stabilizer, etc.

[0003] In a traditional high - voltage drive power supply, a heat - dissipation device is usually installed inside, and air inlet holes are arranged at the bottom. When air flows in from the air inlet holes and is discharged to the exhaust holes for heat dissipation, dust and debris will be brought into the power supply interior. Especially for power supplies installed in areas with more dust and greater pollution, over time, not only will the original heat - dissipation effect of the power supply be affected, but also dust will accumulate inside the power supply, causing damage to components. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a high - voltage drive power supply with a dust - proof structure is proposed.

[0005] In order to achieve the above - mentioned purpose, the utility model adopts the following technical scheme:

[0006] A high - voltage drive power supply with a dust - proof structure includes a power - supply body. The power - supply body includes a housing and a cover plate. Air inlet holes are arranged at the bottom of the housing, an air outlet is arranged on one side of the housing, an exhaust fan is arranged at the position of the air outlet, a dust - proof component is arranged above the air inlet holes, and cleaning components are arranged on both the upper and lower sides of the air inlet holes;

[0007] The dust - proof component includes an electrostatic adsorption plate and filter cotton, and the filter cotton, the electrostatic adsorption plate, and the air inlet holes are arranged from top to bottom;

[0008] A controller is arranged inside the power - supply body.

[0009] Furthermore, the cleaning component includes a first connecting plate disposed above the air inlet hole and a second connecting plate disposed below the air inlet hole. A plurality of first cleaning brushes are fixedly installed on the lower surface of the first connecting plate, and a plurality of second cleaning brushes are fixedly installed on the upper surface of the second connecting plate. Installation grooves are formed in both inner sides of the housing. A motor is fixedly installed in one of the installation grooves. The motor is electrically connected to the controller. The motor is electrically connected to a timer. The timer is fixedly connected to the controller through a wire. A threaded rod is fixedly installed at the output end of the motor. A threaded block is spirally installed on the threaded rod. The threaded block is fixedly connected to the first connecting plate. A guide rod is fixedly installed in the other installation groove. A guide block is slidably installed on the guide rod. The guide block is fixedly connected to the first connecting plate. Connecting pieces are fixedly installed at both ends of the second connecting plate. The guide block and the threaded block are fixedly connected to the second connecting plate through the connecting pieces.

[0010] Furthermore, both the air inlet hole and the first cleaning brush are arranged in an inverted conical shape.

[0011] Furthermore, the first connecting plate and the second connecting plate are installed in non - same vertical planes.

[0012] Furthermore, the electrostatic adsorption plate is arranged in a wavy shape and through holes for gas circulation are arranged on its surface.

[0013] Furthermore, brush hairs are fixedly installed on the outer surfaces of the threaded block and the guide block. The brush hairs are used for cleaning the installation groove.

[0014] Furthermore, first sliding grooves for the first connecting plate to slide are arranged on both sides of the housing, and second sliding grooves for the second connecting plate to slide are arranged at the bottom of the housing. The installation groove, the first sliding groove, and the second sliding groove are arranged in a through - through manner.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. By providing the air inlet hole and the dust - proof component, the present utility model reduces the problem of excessive dust accumulation inside the power supply body due to heat dissipation requirements through three - layer dust - proof measures of filter cotton, electrostatic adsorption plate, and air inlet hole arranged from top to bottom. And the air inlet hole, as the first component in contact with outside dust, can pre - block larger debris, while the electrostatic adsorption plate and the filter cotton can better filter smaller particulate matters, thereby improving the dust - proof performance of the power supply body. The wavy electrostatic adsorption plate can adsorb more small particulate matters in a smaller installation volume.

[0017] 2. The utility model can clean the air inlet holes with the most accumulated dust by setting up a cleaning component, avoiding the loss of the original heat dissipation function caused by the blockage of the air inlet holes. Moreover, the first cleaning brush and the second cleaning brush do not clean the same air inlet hole simultaneously, but in a way that one cleans first and the other cleans later, thus avoiding the problem that the first cleaning brush and the second cleaning brush block the air inlet hole simultaneously, resulting in the inability to clean the dust.

[0018] 3. By setting up bristles, while the motor is working, the bristles on the guide block and the threaded block clean the dust that has flowed into the installation groove, preventing the installation groove from being blocked, so as not to affect the smooth operation of the cleaning component, thereby improving the dust-proof performance of the power supply component.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Refer to Figures 1 - 4 , Figure 8 , a high-voltage drive power supply with a dust-proof structure, including a power supply body 1. The power supply body 1 includes a housing 2 and a cover plate 3. An air inlet 4 is provided at the bottom of the housing 2, and an air outlet 5 is provided on one side of the housing 2. An exhaust fan is provided at the position of the air outlet 5. A dust-proof component is provided above the air inlet 4, and cleaning components are provided on the upper and lower sides of the air inlet 4;

[0030] The dust-proof component includes an electrostatic adsorption plate 6 and a filter cotton 7. The filter cotton 7, the electrostatic adsorption plate 6, and the air inlet 4 are arranged from top to bottom;

[0031] A controller is provided inside the power supply body 1;

[0032] Different from the design of the traditional drive power supply that only sets metal filter holes, this application reduces the problem of excessive dust accumulation inside the power supply body 1 due to heat dissipation requirements through three-layer dust-proof measures of the filter cotton 7, the electrostatic adsorption plate 6, and the air inlet 4 arranged from top to bottom. And the air inlet 4, as the first component in contact with the outside dust, can pre-block larger debris, while the electrostatic adsorption plate 6 and the filter cotton 7 can better filter smaller particulate matter, thereby improving the dust-proof performance of the power supply body 1.

[0033] Refer to Figures 2 - 7, specifically: The cleaning component includes a first connecting plate 8 disposed above the air inlet 4 and a second connecting plate 9 disposed below the air inlet 4. A plurality of first cleaning brushes 10 are fixedly installed on the lower surface of the first connecting plate 8, and a plurality of second cleaning brushes 11 are fixedly installed on the upper surface of the second connecting plate 9. Installation grooves 12 are formed in both inner sides of the housing 2. A motor 13 is fixedly installed in one of the installation grooves 12. The motor 13 is electrically connected to the controller. The motor 13 is electrically connected to a timer. The timer is fixedly connected to the controller through a wire. A threaded rod 14 is fixedly installed at the output end of the motor 13. A threaded block 15 is helically installed on the threaded rod 14. The threaded block 15 is fixedly connected to the first connecting plate 8. A guide rod 16 is fixedly installed in the other installation groove 12. A guide block 17 is slidably installed on the guide rod 16. The guide block 17 is fixedly connected to the first connecting plate 8. Connecting members 18 are fixedly installed at both ends of the second connecting plate 9. The guide block 17 and the threaded block 15 are fixedly connected to the second connecting plate 9 through the connecting members 18. The motor 13 drives the threaded rod 14 to rotate. At this time, the threaded block 15 drives the first connecting plate 8 and the first cleaning brushes 10 to move above the air inlet 4. Driven by the connecting members 18, the second connecting plate 9 and the second cleaning brushes 11 synchronously move below the air inlet 4. The two clean the air inlet 4 where the most dust accumulates, preventing the air inlet 4 from being blocked and resulting in the loss of the original heat dissipation function.

[0034] Specifically: A controller is provided inside the power supply body 1. The controller is electrically connected to the motor 13. The motor 13 is electrically connected to a timer. The timer is fixedly connected to the controller through a wire. When the power supply body 1 is not working, the controller controls the motor 13 to rotate. After the timer determines that the cleaning time has reached, the motor 13 is powered off, and the cleaning component does not work at this time.

[0035] Refer to Figure 2 、 Figure 7 , specifically: The air inlet 4 and the first cleaning brushes 10 are both arranged in an inverted cone shape, so that the cleaning brushes can more conveniently extend into the air inlet 4 to prevent the air inlet 4 from being blocked.

[0036] Refer to Figure 2 、 Figure 6 、 Figure 7 , specifically: The first connecting plate 8 and the second connecting plate 9 are installed in non - co - planar vertical planes. The first cleaning brushes 10 and the second cleaning brushes 11 do not clean the same air inlet 4 at the same time, but clean in a way that one cleans first and the other cleans later. This avoids the problem that the first cleaning brushes 10 and the second cleaning brushes 11 block the air inlet 4 at the same time, preventing dust from being cleaned out.

[0037] Refer to Figure 7, specifically: The electrostatic adsorption plate 6 is arranged in a wavy shape and has through holes for gas circulation on its surface. The electrostatic adsorption plate 6 in a wavy shape can adsorb more small particles with a smaller installation volume.

[0038] Refer to Figure 1 , Figure 5 , Figure 6 , specifically: Brush hairs 19 are fixedly installed on the outer surfaces of the threaded block 15 and the guide block 17. The brush hairs 19 are used to clean the installation groove 12. While the motor 13 is working, the brush hairs 19 on the guide block 17 and the threaded block 15 clean the dust that has flowed into the installation groove 12, preventing the installation groove 12 from being blocked, so as not to affect the smooth operation of the cleaning component, thereby improving the dust-proof performance of the power supply component.

[0039] Refer to Figures 2 - 4 , specifically: First sliding grooves 20 for the first connecting plate 8 to slide are provided on both sides of the housing 2, and second sliding grooves 21 for the second connecting plate 9 to slide are provided at the bottom of the housing 2. The installation groove 12, the first sliding grooves 20, and the second sliding grooves 21 are arranged in a through manner.

[0040] Working principle: Different from the design of only setting metal filter holes in traditional drive power supplies, in this application, three dust-proof measures of the filter cotton 7, the electrostatic adsorption plate 6, and the air inlet hole 4 arranged from top to bottom are adopted to reduce the problem of excessive dust accumulation inside the power supply body 1 due to heat dissipation requirements. And the air inlet hole 4, as the first component in contact with the outside dust, can pre-block larger debris, while the electrostatic adsorption plate 6 and the filter cotton 7 can better filter smaller particles, thereby improving the dust-proof performance of the power supply body 1. The electrostatic adsorption plate 6 in a wavy shape can adsorb more small particles with a smaller installation volume;

[0041] When the power supply body 1 is not working, the controller controls the motor 13 to rotate. The motor 13 drives the threaded rod 14 to rotate. At this time, the threaded block 15 drives the first connecting plate 8 and the first cleaning brush 10 to move above the air inlet hole 4. Driven by the connecting member 18, the second connecting plate 9 and the second cleaning brush 11 move synchronously below the air inlet hole 4. The two clean the air inlet hole 4 where the most dust accumulates, preventing the air inlet hole 4 from being blocked and resulting in the loss of the original heat dissipation function. Thanks to the staggered arrangement of the first connecting plate 8 and the second connecting plate 9, the first cleaning brush 10 and the second cleaning brush 11 do not clean the same air inlet hole 4 at the same time, but clean in the way that one cleans first and the other cleans later. This avoids the problem that the first cleaning brush 10 and the second cleaning brush 11 block the air inlet hole 4 at the same time, preventing the dust from being cleaned out. At the same time, both the air inlet hole 4 and the first cleaning brush 10 are set in an inverted cone shape, enabling the cleaning brush to more conveniently extend into the air inlet hole 4 to prevent the air inlet hole 4 from being blocked. By the forward and reverse rotation of the motor 13, the upper and lower sides of the air inlet hole 4 are continuously cleaned. After the timer determines that the cleaning time has reached, the motor 13 is powered off, and the cleaning component does not work at this time;

[0042] While the motor 13 is working, the bristles 19 on the guide block 17 and the threaded block 15 clean the dust that has flowed into the installation groove 12, preventing the installation groove 12 from being blocked and affecting the smooth operation of the cleaning component, thereby improving the dust-proof performance of the power supply component.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
