Description

Technical Field

[0001] This invention relates to the technical field of power control cabinets, and more particularly to an outdoor modular power control cabinet based on the Internet of Things and its usage method. Background Technology

[0002] A power control cabinet is a type of control cabinet used to store power control modules (multiple IGBT chip integrated modules). Based on the Internet of Things, it realizes power control and association between multiple power control modules, thereby achieving real-time perception, communication, PTZ connection and terminal control of power data, and realizing balanced layout and distribution of power data.

[0003] Existing power control cabinets come in various models, such as the power control cabinet with publication number CN115548912A, which includes a cabinet body and a cleaning device. The cabinet body has an internal cavity for housing electrical components. The cabinet body has multiple ventilation holes communicating with the cavity, and a cleaning port is provided on the cabinet body. The cleaning device includes a sliding plate and a cleaning component, which is connected to the sliding plate. Existing power control cabinets mostly use natural ventilation through heat dissipation holes to dissipate heat. When the internal temperature of the power control cabinet is high, the heat dissipation efficiency is low. Moreover, existing power control cabinets cannot achieve internal dehumidification. If the external humidity is high, external moisture will enter the control cabinet through the heat dissipation holes, causing the power control modules to become damp and damaged. For example, the existing technology mentioned above only uses cleaning ports and heat dissipation holes to achieve natural ventilation and heat dissipation of the power control cabinet. This heat dissipation method produces small airflow fluctuations and has low heat exchange efficiency. At the same time, the device cannot dehumidify the inside of the control cabinet. If the humidity inside the cabinet is high, the power control module inside is easily damaged by moisture, which has certain limitations. Therefore, there is an urgent need to design an outdoor modular power control cabinet based on the Internet of Things and its usage method to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an outdoor modular power control cabinet based on the Internet of Things and its usage method, thus solving the problems mentioned in the background section.

The air-generating impeller is fixedly installed on the drive roller and located inside the air-expelling box. An air-guiding mechanism is provided on the air-expelling box.

[0009] Preferably, the air guiding mechanism includes an air suction component fixedly installed on the second partition plate for adsorbing moisture in the storage area, and an air suction pipe is fixedly connected between the air suction component and the air duct box.

A linkage gear is fixedly installed on each linkage shaft, and a linkage toothed belt meshes together among multiple linkage gears.

[0011] Preferably, the air return assembly includes multiple air return pipes fixedly connected to the partition plate, an air blowing component is fixedly installed on the partition plate, and the air blowing component cooperates with multiple flipping frames.

Each support plate is fixedly installed with a sealing plate by multiple shape memory alloy springs, and each sealing plate cooperates with the corresponding connecting pipe. When the shape memory alloy spring is heated to the deformation threshold, it automatically contracts and deforms, pulling the sealing disc to move and separate from the connecting pipe, thus releasing the sealing state of the connecting pipe.

[0013] Preferably, the exhaust assembly includes an exhaust component fixedly installed on the upper cabinet, the exhaust component is provided with a plurality of exhaust pipes for exhausting air, and the exhaust box is provided with a dust collection box for collecting dust.

[0014] A method for using an outdoor modular power control cabinet based on the Internet of Things (IoT), for the aforementioned outdoor modular power control cabinet, includes the following steps: S1. When multiple power control modules in the power control cabinet are working, they use temperature and humidity sensors to detect the temperature and humidity in the storage area in real time. S2. When the humidity in the storage area is high, the air-generating impeller in the air-inducing component rotates to adsorb the moisture in the storage area into the adsorption component, and the moisture is adsorbed by the activated carbon adsorption plate. S3. The adsorbed dry air is discharged back into the storage area inside the upper cabinet through the return air component; S4. When the temperature in the storage area is high, the air impeller in the air induced assembly rotates to adsorb the high-temperature hot air in the storage area into the adsorption assembly. The heat of the high-temperature hot air desorbs the activated carbon adsorption plate and discharges the desorbed moisture to the outside of the upper cabinet through the exhaust assembly. S5. While high-temperature hot air is being emitted, the ventilation components are automatically activated by the heat, and cold air from outside the ventilation components is drawn into the storage area, completing the circulation and replacement of hot and cold air in the storage area.

[0015] This invention provides an outdoor modular power control cabinet based on the Internet of Things and its usage method. It has the following beneficial effects: 1. When this power control cabinet is in operation, it can detect the temperature and humidity changes in the storage area in real time with the help of temperature and humidity sensors. Then, it can adjust the temperature and humidity in the storage area in real time through the control panel, so that the multiple power control modules in the storage area can always work in a suitable environment, thereby improving the operational stability of the power control modules.

[0016] 2. When this power control cabinet is working, it can quickly remove moisture from the storage area by using the negative pressure suction generated by the rotation of the air impeller when the humidity in the storage area is too high. The moisture is then conducted to the activated carbon adsorption plate for adsorption, and the water vapor in the moisture is removed and converted into dry air and returned to the storage area. This achieves automatic treatment of moisture in the storage area, and there is no need to replace it with external moisture during the treatment process, which can avoid secondary pollution caused by external moisture entering the storage area.

[0017] 3. When this power control cabinet is working, during the moisture adsorption process, the adsorption components can flexibly control multiple activated carbon adsorption plates to automatically rotate, which can effectively increase the contact range between the activated carbon adsorption plates and the moisture, improve the adsorption efficiency of the activated carbon adsorption plates, and achieve better moisture adsorption and removal effect.

[0018] 4. When this power control cabinet is working, it can adsorb the high-temperature hot air in the storage area into the activated carbon adsorption plate when the temperature in the storage area is too high. It can also use the heat of the high-temperature hot air to desorb and regenerate the activated carbon adsorption plate, remove the moisture in the activated carbon adsorption plate and discharge it. At the same time, it can adsorb cold air from outside into the storage area to replenish it, thus completing the rapid cooling of the storage area. It can effectively increase the air flow speed in the storage area and achieve better heat dissipation and cooling effect.

[0019] In summary, this invention can monitor the temperature and humidity of the power control cabinet in real time. When the humidity is too high, it can use activated carbon adsorption plates combined with internal circulation to quickly remove moisture. When the temperature is too high, it can improve the exchange efficiency of hot and cold air to achieve rapid cooling. At the same time, it can simultaneously achieve desorption and regeneration of activated carbon adsorption plates during high-temperature hot air exchange, resulting in better functionality and effectively improving the overall service life.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Example 1: Refer to Figures 1-4 as well as Figure 7 An outdoor modular power control cabinet based on the Internet of Things (IoT) includes an upper cabinet 2 mounted on a lower cabinet 1. The upper cabinet 2 contains multiple IoT-based power control modules. Each power control module is an integrated control module that integrates multiple IGBT chips. The IGBT chip is an insulated gate bipolar transistor, which is mainly used to realize high-voltage, high-power, and rapid switching and control the efficient conversion of electrical energy.

[0025] This power control cabinet also includes: The placement unit is located inside the upper cabinet 2. The placement unit includes a first partition 4 and a second partition 5 that are fixedly installed inside the upper cabinet 2, and multiple support components are installed between the first partition 4 and the second partition 5. The support assembly includes a placement platform 6 that is slidably installed between partition plate 4 and partition plate 5, and the power control module is placed on the placement platform 6. The placement platform 6 enables the stable placement and support of the power control module, ensuring the stable operation of the power control module.

[0026] Two reset spring rods 16 for resetting are fixedly installed between the placement platform 6 and the upper cabinet 2. A control handle is fixedly installed on the placement platform 6. The operator can pull the control handle to move the placement platform 6, so that the power control module on the placement platform 6 can be pulled out to the outside of the upper cabinet 2, which facilitates the installation, disassembly and maintenance of the power control module.

[0027] When the placement platform 6 is pulled out, it will stretch two reset spring rods 16. After the power control module on the placement platform 6 has been repaired, the control handle can be released. At this time, the reset spring rods 16 will retract and reset themselves, driving the placement platform 6 back into the upper cabinet 2, completing the automatic return of the placement platform 6, which is more convenient and time-saving.

[0028] The area between partition 4 and partition 5 is named the storage area. Partition 4 is equipped with a temperature and humidity sensor 12 for detecting the temperature and humidity in the storage area. The temperature and humidity sensor 12 can detect the temperature and humidity changes in the storage area in real time and adjust the temperature and humidity in the storage area in real time, so that the multiple power control modules in the storage area always work in a suitable environment, thereby improving the operational stability of the power control modules.

[0029] The dehumidification unit is located between the upper cabinet 2 and the lower cabinet 1. When the humidity in the storage area is too high, the dehumidification unit can efficiently remove moisture by adsorbing moisture through negative pressure and real-time adsorption by activated carbon adsorption plate 21. It can also circulate dry air back into the storage area. There is no need to replace the external air during the circulation dehumidification process, which can avoid secondary moisture absorption, effectively protect the power control module from moisture damage, and improve the stability of operation.

[0030] The heat dissipation unit is located inside the upper cabinet 2. When the temperature in the storage area is too high, the heat dissipation unit can automatically and efficiently exhaust hot air and automatically introduce external cold air to complete the heat exchange. When the hot air is exhausted, it can come into efficient contact with the activated carbon adsorption plate 21, realizing the automatic desorption and regeneration of the activated carbon adsorption plate 21, which greatly improves the cooling efficiency and extends the overall service life of the power control cabinet.

[0031] A sealing cabinet door 3 is rotatably installed on the upper cabinet 2 to achieve a seal. The sealing cabinet door 3 effectively seals the upper cabinet 2, preventing external moisture and dust from entering the storage area and causing contamination during operation.

[0032] A control panel 7 is installed on the sealed cabinet door 3. The control panel 7 is used to control the opening and closing and operation status of the dehumidification unit and the heat dissipation unit, so as to realize the automatic regulation of temperature and humidity inside the upper cabinet 2.

[0033] Example 2: Refer to Figures 3-6 as well as Figures 8-12 The technical solution that differs from that of Embodiment 1 is as follows: the dehumidification unit includes an air intake component, an adsorption component and a return air component. The air intake component is provided with an air-generating impeller 28 for generating negative pressure to draw in the material. The adsorption component is provided with multiple activated carbon adsorption plates 21 for adsorbing moisture. The return air component is used to realize the circulation and replacement of air in the upper cabinet 2.

[0034] The air intake assembly includes a servo motor 10 fixedly installed in the lower cabinet 1, and a drive roller 23 fixedly installed on the drive end of the servo motor 10. An air intake box 11 is fixedly installed in the lower cabinet 1, and the air intake box 11 is rotatably connected to the drive roller 23. The air-generating impeller 28 is fixedly installed on the drive roller 23 and located in the air intake box 11. When the temperature and humidity sensor 12 detects that the humidity in the storage area is too high, the servo motor 10 will start to drive the drive roller 23 to rotate. The rotation of the drive roller 23 will drive the air-generating impeller 28 to rotate. When the air-generating impeller 28 rotates, it will generate negative pressure suction in the air box 11, and the moisture in the storage area will be adsorbed through the negative pressure suction.

[0035] The air duct box 11 is equipped with an air guiding mechanism, which includes an air suction component 18 fixedly installed on the partition plate 2 5 for adsorbing moisture in the storage area, and an air suction pipe 19 is fixedly connected between the air suction component 18 and the air duct box 11. A barrier inclined plate 29 is fixedly installed inside the air duct box 11, and two filter inclined plates 30 for blocking dust are fixedly installed on the barrier inclined plate 29. The negative pressure suction will act on the suction component 18 through the suction pipe 19, that is, the moisture and dust in the storage area will be simultaneously adsorbed into the air box 11 through the suction component 18 and the suction pipe 19, thus completing the removal of moisture in the storage area.

[0036] The air duct 11 is equipped with a dust discharge box 17 for collecting dust. After the moisture and dust enter the air duct 11, they will come into contact with the filter plate 30 on the baffle plate 29. At this time, the dust will be blocked by the filter plate 30 and can be discharged through the dust discharge box 17 periodically, while the moisture will enter the lower part of the baffle plate 29 through the filter plate 30 to continue to be conducted.

[0037] In a further embodiment, the adsorption assembly includes multiple linkage shafts 14 rotatably mounted between the upper cabinet 2 and the lower cabinet 1, each linkage shaft 14 is fixedly mounted with a flipping frame 13, and multiple activated carbon adsorption plates 21 are respectively fixedly mounted on the multiple flipping frames 13. A drive wheel 24 is fixedly installed on the drive roller 23, a driven wheel 25 is fixedly installed on one of the linkage shafts 14, and a transmission belt 22 is sleeved between the drive wheel 24 and the driven wheel 25. A linkage gear 27 is fixedly installed on each linkage shaft 14, and a linkage toothed belt 26 meshes together among the multiple linkage gears 27. As the drive roller 23 rotates, it drives the drive wheel 24 to rotate. When the drive wheel 24 rotates, it drives the driven wheel 25 to rotate under the transmission action of the transmission belt 22. The diameter of the drive wheel 24 is much smaller than the diameter of the driven wheel 25, so that the speed of the driven wheel 25 is much smaller than the speed of the drive wheel 24. This controls the speed of the driven wheel 25 to be relatively low, so as not to affect the rotation and adsorption of the air-generating impeller 28.

[0038] When the driven wheel 25 rotates, it drives the linkage shaft 14 on it to rotate. When the linkage shaft 14 rotates, it drives the linkage gear 27 on it to rotate. When the linkage gear 27 rotates, it drives the other two linkage gears 27 to rotate together under the transmission action of the linkage belt 26, which in turn drives multiple linkage shafts 14 to rotate synchronously.

[0039] When the linkage shaft 14 rotates, it drives the flipping frame 13 on it to rotate. When the flipping frame 13 rotates, it drives the activated carbon adsorption plate 21 on it to rotate synchronously. This changes the contact range and time between the activated carbon adsorption plate 21 and the moisture, so that different areas on the activated carbon adsorption plate 21 are in uniform contact with the moisture, avoiding local adsorption saturation, improving the overall adsorption efficiency, and accelerating the moisture removal speed. At the same time, the rotation of the activated carbon adsorption plate 21 will disturb the airflow around it, reduce the airflow obstruction during adsorption and desorption, and make the moisture adsorption and heat exchange smoother, thus optimizing the temperature and humidity control effect.

[0040] The air return assembly includes multiple air return pipes 15 fixedly connected to the partition plate 4. An air blowing component 20 is fixedly installed on the partition plate 4, and the air blowing component 20 cooperates with multiple flipping frames 13. An air blowing pipe 31 for conducting air is fixedly connected between the air blowing component 20 and the air induced box 11. The suction pipe 19 and the air blowing pipe 31 are located at the upper and lower parts of the blocking inclined plate 29, respectively. The moisture in the air box 11 is conducted to the air blowing component 20 through the air blowing pipe 31, and then blown to the side of the partition plate 4 through the air blowing component 20. When it flows on the side of the partition plate 4, it comes into contact with multiple flipped activated carbon adsorption plates 21. At this time, the activated carbon adsorption plates 21 will adsorb the water vapor in the moisture and convert the moisture into dry air, thus completing the adsorption treatment of water vapor in the moisture. The adsorbed dry air will return to the storage area through multiple return air pipes 15 to replenish the air in the storage area. This will achieve the replacement of moisture with dry air in the storage area, complete the removal of moisture, and enable the power control module in the storage area to work in a dry environment, thereby improving the working stability of the power control module.

[0041] Example 3: Refer to Figures 1-4 as well as Figures 13-15 The difference between this embodiment and embodiment two is that the heat dissipation unit includes a ventilation component and an exhaust component. The ventilation component is used to replace the air inside and outside the upper cabinet 2, and the exhaust component is used to discharge the hot air inside the upper cabinet 2 and realize the desorption and regeneration of the activated carbon adsorption plate 21.

[0042] When the temperature in the storage area is high, the induced draft assembly will start and drive the air impeller 28 to rotate, adsorbing the high-temperature hot air in the storage area and blowing it to the left side of the partition plate 4. At this time, the high-temperature hot air will come into contact with multiple rotating activated carbon adsorption plates 21, thereby desorbing the activated carbon adsorption plates 21 at high temperature, realizing the automatic regeneration of the activated carbon adsorption plates 21, and improving their service life.

[0043] The exhaust assembly includes an exhaust component 8 fixedly installed on the upper cabinet 2. The exhaust component 8 is equipped with multiple exhaust pipes for exhaust. The desorbed high-temperature hot gas will be converted into high-temperature humid gas. At this time, the exhaust pipes on the exhaust component 8 can be opened (at the same time, the multiple return pipes 15 on the partition plate 4 are closed to prevent the high-temperature humid gas from returning to the storage area), so that the high-temperature humid gas can be directly discharged to the outside of the upper cabinet 2 through the exhaust pipes, thus completing the discharge of high-temperature humid gas.

[0044] In a further embodiment, the ventilation assembly includes multiple heat conduction boxes 32 fixedly installed on the partition plate 2 5, multiple air exchange boxes 9 fixedly installed on the upper cabinet 2, and multiple connecting pipes 33 for conducting external cold air are fixedly connected between each air exchange box 9 and the corresponding heat conduction box 32. Each heat conduction box 32 has a support plate 34 fixedly installed inside, and each support plate 34 has a sealing plate 36 fixedly installed on it by multiple memory alloy springs 35. Each sealing plate 36 cooperates with the corresponding connecting pipe 33. When the temperature in the storage area is too high, the shape memory alloy spring 35 in the heat conduction box 32 absorbs heat and reaches the deformation threshold, and will automatically contract to pull the sealing plate 36 to move and separate from the connecting pipe 33, thus releasing the sealing state of the connecting pipe 33 (in the initial state, the sealing plate 36 will seal the connecting pipe 33). At this time, the heat conduction box 32, the multiple connecting pipes 33 and the ventilation box 9 are in a connected state, that is, the storage area is in a connected state with the outside of the upper cabinet 2.

[0045] Once the storage area has cooled down, the shape memory alloy spring 35 will automatically cool down and automatically extend and reset when it reaches the deformation threshold. This will then push the sealing plate 36 to move onto the connecting pipe 33, continuing to seal the connecting pipe 33 and preventing external air from entering the storage area.

[0046] While the high-temperature hot air in the storage area is being adsorbed, the negative pressure suction generated in the storage area will directly adsorb the external cold air into the storage area through the air exchange box 9, multiple connecting pipes 33 and heat conduction box 32 to replenish it. This achieves the simultaneous removal of high-temperature hot air from the storage area and the entry of cold air, completing the direct replacement of hot and cold air in the storage area. This enables rapid cooling of the storage area and provides better heat dissipation and cooling effect.

[0047] Each air exchange box 9 is fixedly installed with a dust-blocking filter plate 37. The dust-blocking filter plate 37 is used to block dust in the outside air while the cold air is being replaced, so as to prevent the outside air from entering the storage area and causing pollution.

[0048] The working principle of this power control cabinet is as follows: When this power control cabinet is working, it uses temperature and humidity sensor 12 to detect changes in temperature and humidity in the storage area in real time, which facilitates real-time control of temperature and humidity in the storage area. When the temperature and humidity sensor 12 detects that the humidity in the storage area is too high, the servo motor 10 will start and drive the drive roller 23 to rotate. The rotation of the drive roller 23 will drive the air-generating impeller 28 to rotate. When the air-generating impeller 28 rotates, it will generate negative pressure suction in the air box 11. The negative pressure suction will act on the air-absorbing component 18 through the air-absorbing pipe 19. That is, the moisture and dust in the storage area will be simultaneously adsorbed into the air box 11 through the air-absorbing component 18 and the air-absorbing pipe 19, thus completing the removal of moisture in the storage area.

[0049] The moisture in the air box 11 is conducted to the air blowing component 20 through the air blowing pipe 31, and then blown to the side of the partition plate 4 through the air blowing component 20. When it flows on the side of the partition plate 4, it comes into contact with multiple flipped activated carbon adsorption plates 21. At this time, the activated carbon adsorption plates 21 will adsorb the water vapor in the moisture and convert the moisture into dry air, thus completing the adsorption treatment of water vapor in the moisture. The adsorbed dry air will return to the storage area through multiple return air pipes 15 to replenish the air in the storage area. This will achieve the replacement of moisture with dry air in the storage area, complete the removal of moisture, and enable the power control module in the storage area to work in a dry environment, thereby improving the working stability of the power control module.

[0050] When the temperature in the storage area is high, the air intake component will start and drive the air impeller 28 to rotate, adsorbing the high-temperature hot air in the storage area and blowing it to the left side of the partition plate 4. At this time, the high-temperature hot air will come into contact with multiple rotating activated carbon adsorption plates 21, thereby desorbing the activated carbon adsorption plates 21 at high temperature, realizing the automatic regeneration of the activated carbon adsorption plates 21, and improving their service life. When the temperature in the storage area is too high, the shape memory alloy spring 35 in the heat conduction box 32 absorbs heat and reaches the deformation threshold, and will automatically contract to pull the sealing plate 36 to move and separate from the connecting pipe 33, thus releasing the sealing state of the connecting pipe 33. At this time, the heat conduction box 32, the multiple connecting pipes 33 and the ventilation box 9 are in a connected state, that is, the storage area is in a connected state with the outside of the upper cabinet 2.

[0051] While the high-temperature hot air in the storage area is being adsorbed, the negative pressure suction generated in the storage area will directly adsorb the external cold air into the storage area through the air exchange box 9, multiple connecting pipes 33 and heat conduction box 32 to replenish it. This achieves the simultaneous removal of high-temperature hot air from the storage area and the entry of cold air, completing the direct replacement of hot and cold air in the storage area. This enables rapid cooling of the storage area and provides better heat dissipation and cooling effect.

[0052] This invention also provides a method for using an outdoor modular power control cabinet based on the Internet of Things, for the aforementioned outdoor modular power control cabinet, including the following steps: S1. When multiple power control modules in the power control cabinet are working, they use temperature and humidity sensor 12 to detect the temperature and humidity in the storage area in real time. S2. When the humidity in the storage area is high, the air-generating impeller 28 in the air-generating component rotates to adsorb the moisture in the storage area into the adsorption component, and the moisture is adsorbed by the activated carbon adsorption plate 21. S3. The adsorbed dry air is discharged back into the storage area inside the upper cabinet 2 through the return air component; S4. When the temperature in the storage area is high, the air impeller 28 in the air induced assembly rotates to adsorb the high-temperature hot air in the storage area into the adsorption assembly.
