Description

Technical Field

[0001] This invention relates to the field of power quality monitoring technology, and in particular to a medium- and low-speed maglev network-level power quality monitoring system and optimization method. Background Technology

[0002] With the continuous development and popularization of medium- and low-speed maglev transportation systems, power quality monitoring at the medium- and low-speed maglev network level is necessary to ensure the operational safety and reliability of maglev trains. Currently, power quality monitoring often requires monitoring multiple indicators, which leads to a large amount of heat generated during operation. Existing devices use fans to dissipate heat from the internal components. During this process, when air comes into contact with the rotating mechanism, the fan's force causes the rotating blades to rotate, thus diffusing the air and increasing its flow speed, thereby improving the heat dissipation effect inside the device. However, medium- and low-speed maglev trains typically operate outdoors, requiring power quality monitoring at multiple outdoor locations. Traditional monitoring devices draw in cool external air through ventilation openings to dissipate heat from the components. If the outdoor air has high humidity or contains rainwater, it can damage the components.

[0003] In the prior art, by setting a moisture filter membrane and a heater inside the device, the moisture in the humid air is further filtered through the moisture filter membrane, and then the heater heats and dries the used moisture filter membrane so that it can be reused.

[0004] In the aforementioned prior art, after repeated water absorption and drying, the structure of the moisture filter membrane undergoes repeated contraction and expansion, making it prone to deformation, wear, aging, or damage, thus affecting the moisture filtration effect. Therefore, the moisture filter membrane needs to be replaced frequently. At the same time, due to the large coverage area of ​​the medium- and low-speed maglev network, it is necessary to set up multiple power quality monitoring devices. Ultimately, this leads to the need for frequent replacement and maintenance of the moisture filter membranes of multiple monitoring devices, resulting in a large workload and requiring a lot of effort from staff, which is very inconvenient. Summary of the Invention

[0029] The monitoring unit is located inside the monitoring chamber 2, the cooling unit is located in the cooling chamber 4, the rotating unit is located in the filter chamber 3, and multiple moisture filtration components are sequentially arranged around the rotating unit. The monitoring box 1 also has a replacement slot 6, and the replacement chamber 5 is connected to the filter chamber 3 through the replacement slot 6. Two lifting components 8 are sequentially located inside the replacement chamber 5, and a powerful electromagnet 7 is located at the output end of the two lifting components 8. The pushing component 9, the receiving chute 10, and the feeding unit are all located inside the replacement chamber 5, and the pushing component 9 and the receiving chute 10 are respectively located on both sides of the lifting component 8. The monitoring chamber 1 is placed in the monitoring position; the power quality of the medium-low speed maglev network is monitored by the monitoring unit; the cooling unit draws outside air into the cooling chamber 4 to cool it down, forming cold air; the cold air enters the filter chamber 3, and the rotating unit drives the moisture filter component to rotate, filtering the moisture in the cold air to obtain dry cold air; the dry cold air is delivered to the monitoring chamber 2 for cooling; the lifting component 8 drives the powerful electromagnet 7 into the replacement slot 6; the powerful electromagnet 7 is energized and moves upward, removing the moisture... The air filter component is sucked out from the rotating unit; the moisture filter component is moved into the replacement chamber 5, and the powerful electromagnet 7 is de-energized; the pushing component 9 pushes it into the receiving sloping groove 10 for storage, and the new moisture filter component is repositioned on the powerful electromagnet 7 after being operated by the feeding unit; the new moisture filter component is moved up and reinstalled on the rotating unit; the lifting component 8 is an electric slide rail, and the pushing component 9 consists of a cylinder and a push plate. The moisture filter component can be pushed by the cylinder pushing the push plate.

[0030] Secondly, the louvered air inlet 11 is located at one end of the cooling chamber 4, and the air intake fan 12 is located between the cooling chamber 4 and the louvered air inlet 11. The cooling chamber 4 has an air inlet 15, and the air intake pipe 13 is located inside the cooling chamber 4. The two ends of the air intake pipe 13 are respectively connected to the air inlet 15 and the filter chamber 3. The first valve body 14 is located at the end of the air intake pipe 13 near the filter chamber 3, and the cooling mechanism is located on one side of the cooling chamber 4. The louvered air inlet 11 can reduce the entry of rainwater. When the air intake fan 12 is activated, it draws outside air into the air intake pipe 13 through the air inlet 15. At the same time, the cooling chamber 4 contains coolant to cool the air intake pipe 13. Then, the first valve body 14 is opened, and the cooled air enters the filter chamber 3 for moisture filtration.

[0031] Meanwhile, multiple cooling fans 16 are sequentially arranged on one side of the cooling chamber 4, and multiple heat-absorbing copper pillars 17 are fixedly connected to the monitoring box 1. One end of each heat-absorbing copper pillar 17 passes through the monitoring box 1 and is located inside the cooling chamber 4. The cooling fans 16 dissipate heat from the heat-absorbing copper pillars 17, and the heat-absorbing copper pillars 17 absorb heat from the coolant, thereby continuously cooling the air.

[0032] In addition, the rotating component 18 is disposed on one side of the monitoring chamber 1, one end of the rotating shaft 19 is fixedly connected to the output end of the rotating component 18, and the other end of the rotating shaft 19 is rotatably connected to the inner wall of the filter chamber 3. A plurality of support frames 21 are sequentially disposed outside the rotating shaft 19, a plurality of magnetic plates 20 are respectively disposed on the inner wall of the corresponding support frame 21, and a plurality of humidity sensors 22 are sequentially distributed around the outside of the rotating shaft 19 and located between two corresponding support frames 21. The filter chamber 3 is connected to the monitoring chamber 2, and the second valve body 23 is disposed at the connection between the filter chamber 3 and the monitoring chamber 2. The rotating component 18 is a self-locking motor; the rotating component 18 drives the rotating shaft 19 to rotate, the support frame 21 supports the moisture filter component, thereby driving multiple moisture filter components to rotate, making full contact with the moisture and filtering the moisture. At the same time, the humidity sensor 22 detects the humidity in the air. When the content drops to 10%, it is electrically connected to each component through the monitoring processor 26, thereby stopping the rotation, opening the second valve body 23, closing the first valve body 14, and delivering dry and cold air to the monitoring chamber 2 for cooling.

[0033] Then, the metal frame 24 is disposed inside the support frame 21. The metal frame 24 and the magnetic plate 20 attract each other. The moisture filter membrane 25 is fixedly connected to the metal frame 24 and located inside the metal frame 24. The metal frame 24 supports the moisture filter membrane 25. When the metal frame 24 is installed inside the support frame 21, it is attracted by the magnetic force of the magnetic plate 20, and then the moisture is filtered by the moisture filter membrane 25. In addition, when the powerful electromagnet 7 attracts and removes the moisture filter component, although the magnetic plate 20 cannot be de-energized to cancel the magnetic force, the powerful electromagnet 7 can generate strong magnetism, and the magnetic force is greater than that of the magnetic plate 20. Therefore, the metal frame 24 can be attracted out of the support frame 21. After replacing the new moisture filter component, the powerful electromagnet 7 is de-energized to cancel the magnetic force and then moved down, so that the metal frame 24 can be installed inside the support frame 21.

[0034] Furthermore, the monitoring processor 26 is disposed on the inner bottom wall of the monitoring chamber 2, the two power sensors 27 are symmetrically disposed on the inner side wall of the monitoring chamber 2, the two connectors 28 are symmetrically disposed on both sides of the monitoring box 1, the power sensors 27 are connected to the connectors 28, the power sensors 27 are electrically connected to the monitoring processor 26, the exhaust pipe 29 is connected to the monitoring chamber 2, the check valve 30 is disposed on the exhaust pipe 29, and the two exhaust fans 31 are sequentially disposed inside the monitoring chamber 2. The connector 28 is connected to the connecting line of the medium-low speed maglev network level, transmitting current to the power sensor 27. The power sensor 27 converts the current into a low voltage and small current signal suitable for processing. The monitoring processor 26 analyzes the current signal to complete power quality monitoring. In addition, during cooling, the exhaust fan 31 is activated. One exhaust fan 31 is installed at the exhaust pipe 29 to help expel hot air, and another exhaust fan 31 is installed at the connection between the monitoring chamber 2 and the filter chamber 3 to accelerate the entry of cold air. The exhaust fan 31 delivers hot air to the exhaust pipe 29, thereby opening the valve of the check valve 30 to exhaust air. After exhausting, the check valve 30 closes to prevent outside air from entering the monitoring chamber 2.

[0035] Furthermore, two ejection mechanisms are symmetrically arranged on both sides of the pushing component 9, and two sealing mechanisms are symmetrically arranged on both sides of the replacement slot 6; the placement slot 32 is located on one side of the pushing component 9, the two ends of the spring 33 are movably connected to the inner wall of the replacement chamber 5 and the supporting plate 35 respectively, the two ends of the telescopic rod 34 are fixedly connected to the inner wall of the replacement chamber 5 and the supporting plate 35 respectively, the spring 33 and the telescopic rod 34 are both located inside the placement slot 32, a plurality of moisture filter components are placed in the placement slot 32, the supporting plate 35 abuts against the moisture filter components, the ejection component 36 is located on one side of the monitoring box 1, the output end of the ejection component 36 penetrates the monitoring box 1 and is fixedly connected to the ejection plate 37, and the placement slot 32 has an ejection outlet 38. The pop-out component 36 is a cylinder. The pop-out component 36 drives the pop-out plate 37 to move, pushing the moisture filter component through the pop-out outlet 38 and then to the pushing component 9. The pushing component 9 consists of a cylinder and a push plate. By pushing the push plate with the cylinder, the moisture filter component can be pushed above the powerful electromagnet 7. At this time, the powerful electromagnet 7 is energized to generate magnetic force, which moves it upward and places it in the support frame 21, where it is attracted and fixed by the magnetic plate 20. When one moisture filter component in the placement slot 32 pops out, the spring 33 rebounds, driving the abutment plate 35 to push the other moisture filter components, so that they continue to move to the output end of the pop-out component 36 for subsequent pop-out. The telescopic rod 34 maintains the stability of the abutment plate 35.

[0036] Finally, a door panel 41 is provided at one end of the storage sloping groove 10 and on one side of each of the two placement slots 32. The sealing component 39 is located on one side of the replacement slot 6, and the output end of the sealing component 39 is fixedly connected to the sealing plate 40. The sealing plate 40 and the replacement slot 6 are mutually compatible. When the moisture filter component is not replaced, the sealing component 39 is activated, which moves the sealing plate 40 to seal the replacement slot 6, preventing cold air from entering the replacement chamber 5. At the same time, after the moisture filter component is pushed into the storage sloping groove 10, it accumulates on the inclined surface of the storage sloping groove 10. The storage sloping groove 10 can be removed by opening the door panel 41. The door panels 41 on both sides of the placement slot 32 can also be opened to add new moisture filter components. Each door panel 41 is equipped with a lock to prevent accidental opening.

[0037] When using the medium-low speed maglev network-level power quality monitoring system of this embodiment, the monitoring box 1 is placed in the monitoring position; the power quality of the medium-low speed maglev network-level is monitored by the monitoring unit; the coolant in the cooling chamber 4 cools the air in the air inlet pipe 13 to form cold air; the cold air enters the filter chamber 3, and the rotating unit drives the moisture filter component to rotate, filtering the moisture in the cold air to obtain dry cold air; the dry cold air is delivered to the monitoring chamber 2 for cooling, and finally the exhaust fan 31 is started to discharge hot air through the exhaust pipe 29; when replacement is required, the lifting component 8 drives the powerful electromagnet 7 into the replacement slot 6; the powerful electromagnet 7 is energized and moves upward, adsorbing and moving the metal frame 24 of the moisture filter component downward, sucking it out from the support frame 21, and moving it downward. The device moves into the replacement chamber 5, and then the powerful electromagnet 7 is de-energized. The pushing component 9 pushes it into the storage chute 10 for storage. After the new moisture filter component is processed by the feeding unit, it is repositioned on the powerful electromagnet 7. The new moisture filter component is then moved upward and reinstalled in the support frame 21, where it is fixed by the magnetic plate 20. Through the above structural setup, a large number of moisture filter components are stored in the replacement chamber 5. The component to be replaced is disassembled and pushed into the storage chute 10 by the powerful electromagnet 7, and the new moisture filter component is reinstalled for use. The replacement process is completed automatically without manual intervention. Furthermore, by relying on a large number of moisture filter components as spares, frequent replacements are not required. Only periodic replenishment of spare components is needed, greatly reducing workload and improving replacement efficiency.
