Description
TECHNICAL FIELD
[0001] The utility model relates to power control box technical field more specifically, it relates to an automatic heat dissipation type intelligent power control box. BACKGROUND
[0002] In the existing automatic heat dissipation type intelligent power control box technology, there are some significant problems and limitations, these problems not only affect the performance and reliability of the equipment, also increase the complexity and cost of maintenance.
[0003] First, the power control box internal heat management is a key problem, in the running process, internal electrical components, such as transformer, relay, capacitor, etc., will continuously produce heat, if these heat cannot be effectively dissipated in time, will accumulate in the control box, with the lapse of time, the control box internal temperature will gradually increase, form a continuously deteriorating thermal environment, this temperature rise not only will affect the normal working efficiency of electrical components, may also lead to component life significantly shortened, in extreme cases, too high temperature may even cause component failure or safety accidents, such as insulation material aging, circuit short circuit, in addition, the fluctuation of temperature may also affect the accuracy of precision control system, lead to the performance of the entire power control system decline.
[0004] Secondly, in order to solve the problem of heat accumulation, some devices adopt the active cooling way, usually install cooling fan and equipped with filter plate on the control box, the original intention of this design is through forced air circulation to reduce the temperature in the box, at the same time, use filter plate to block dust and other impurities into the box, however, this scheme has also exposed some problems in long-term use, the most important problem is the maintenance problem of filter plate, with the extension of use time, the outer surface of filter plate will accumulate a lot of dust, fiber and other small particles, these accumulated materials will gradually block the filter hole, seriously affect the air circulation efficiency, when the filtration effect is reduced, not only will weaken the cooling effect, may also lead to small particles into the control box, cause pollution to internal components, therefore, regular cleaning and replacement of filter plate has become necessary maintenance work, however, in many existing designs, the installation and disassembly process of filter plate often involves complex steps, may need to use special tools, this cumbersome operation not only increases the maintenance time, also improves the risk of operation error, may cause the maintenance personnel to cause accidental damage to other components in the operation process.
[0005] In addition, in order to solve the problem of difficult disassembly of the filter plate, some equipment manufacturers try to use quick disassembly mechanisms, which usually use buckles or magnetic fixation and other ways, aiming to simplify the replacement process of the filter plate. However, in the pursuit of convenience, these quick disassembly designs often sacrifice the stability and firmness of the structure. For example, simple buckle mechanisms may not withstand long-term vibration and temperature changes, resulting in a gradual weakening of the fixing effect. Magnetic fixation, although simple to operate, may fail due to magnetic decay or external forces. These problems are particularly evident in the long-term operation environment of the power control box. The continuous vibration generated by the cooling fan during operation can gradually loosen the components of the quick disassembly mechanism. Over time, the fixing effect gradually decreases, and in severe cases, the filter plate may even fall off completely. Once the filter plate falls off, not only will the cooling effect decrease dramatically, but the internal control box may also be directly exposed to the external environment, increasing the risk of dust and other contaminants entering.

[0038] Please refer to Figures 1-3 As a further embodiment of the whole device: the filter plate 3 is provided with a protection frame 27 on one side, and the protection frame 27 is detachably installed on the outer side of the control box 1.
[0039] The inside of the control box 1 is provided with an integrated module 28, and the integrated module 28 is detachably installed at the top end inside the control box 1.
[0040] The control box 1 is movably provided with a box door 29 on one side, and the control box 1 is detachably provided with a mounting frame 30.
[0041] More specifically, when the device needs to be used, various electrical components are installed on the mounting rack 30 inside the control box 1, and the integrated module 28 contains temperature sensors, microcontrollers (MCU) as the core processing unit, power management units, communication interfaces (such as UART, I2C or SPI), memories, relay or transistor switches, LED indicator lights, humidity sensors (optional) and current sensing circuits, etc. In order to realize the connection and control of the cooling fans 2, the integrated module 28 connects each cooling fan 2 through a relay or transistor switch circuit, the power supply line of the cooling fan 2 is connected to the output end of the switch circuit, and the control line is connected to the control end of the switch circuit from the MCU. The MCU controls each switch circuit through the GPIO port and controls the opening of the cooling fan 2 according to the set temperature threshold. In order to realize individual control, an independent temperature threshold can be set for each side cooling fan 2, and the MCU decides whether to open the corresponding cooling fan 2 according to the temperature sensor reading. At the same time, in order to realize the function of opening both sides of the cooling fan 2, a higher temperature threshold can be set, and when the temperature on either side or both sides exceeds this threshold, the MCU opens both cooling fans 2. The program written in the MCU reads temperature data regularly, controls the high and low level of the GPIO port according to the temperature data and the preset threshold, thereby realizing intelligent control of the cooling fan 2. Through this design, the intelligent integrated module 28 can flexibly control the two sides of the cooling fan 2, which can be opened individually as needed, and can be opened on both sides when necessary, realizing intelligent active temperature management. When the internal temperature rises, the integrated module 28 opens the cooling fan 2 on the corresponding side. When the left cooling fan 2 is opened alone, it is in the mode of air extraction, and when the right cooling fan 2 is opened alone, it is in the mode of air blowing. The integrated module 28 will select to start the air extraction mode or the air blowing mode according to different environmental conditions and temperature states. When it is detected that the internal temperature of the device is slightly higher than the normal working temperature, but has not reached the critical value, the integrated module 28 will open the left cooling fan 2 alone to start the air extraction mode, so as to slowly but continuously lower the internal temperature. If the temperature continues to rise or reaches the preset higher threshold, the integrated module 28 will open the right cooling fan 2 alone to switch to the air blowing mode to cool down more quickly. In some cases, if the temperature rises sharply or has reached a dangerous level, the integrated module 28 will open the left and right cooling fans 2 simultaneously to start the air extraction and air blowing modes synchronously to maximize the cooling effect. In addition, the integrated module 28 may also decide which mode to start according to other environmental factors such as humidity and air quality. For example, when the humidity is high, the air extraction mode may be preferred to reduce the internal humidity, and when the air quality is poor, the air extraction mode may also be preferred to improve the internal air environment. Through this intelligent control strategy, the integrated module 28 can flexibly adjust the cooling mode according to the actual needs, ensuring the normal operation of the device and optimizing the energy use efficiency.The filter plate 3 can effectively prevent foreign matters from entering the control box 1 from the ventilation opening, and the guard frame 27 can prevent rainwater from entering the control box 1 from the filter plate 3.
[0042] In summary, the overall device in use or operation: when the filter plate 3 needs to be maintained cleaning or replacement, first rotate the rotating plate 14, so that the rotating plate 14 drives the arc-shaped groove 15 and the circular groove 16 to move, when the circular groove 16 moves to the position concentric with the clamping plate 17, push the locking sleeve 13, the locking sleeve 13 will drive the top rod 18 and the clamping plate 17 to pass through the circular groove 16, at the same time, the locking sleeve 13 will cooperate with the rotating plate 14 to extrude the push spring 25, when the push spring 25 is extruded to the limit, the corresponding clamping plate 17 just passes through the circular groove 16 and moves to the other side of the rotating plate 14, then reverse rotate the rotating plate 14, so that the rotating plate 14 drives the arc-shaped groove 15 and the circular groove 16 to rotate reversely, then the top rod 18 will slide into the arc-shaped groove 15, at the same time, the locking sleeve 13 will be clamped on one side of the rotating plate 14 through the corresponding clamping plate 17, so that the outer end of the locking rod 19 loses the limiting of the locking sleeve 13, then rotate the rotating sleeve 10, the rotating sleeve 10 will drive the locking rod 19 which is slidingly arranged on the side wall to rotate, then the side wall of the locking groove 20 extrudes one end of the locking rod 19, due to the round corner treatment of the edge of the locking groove 20 and the end of the locking rod 19, then one end of the locking rod 19 slides out of the locking groove 20, the other end of the locking rod 19 drives the return spring 26 to stretch, at the same time, the rotating sleeve 10 will drive the release plate 5 to rotate, then the release plate 5 drives the release block 7 to rotate, at the same time, the release block 7 will rotate along the release groove 9, due to the spiral structure design of the release groove 9 and the release block 7, then the release sleeve 8 will drive the unlocking groove 12 which is arranged inside to slide, due to the inclined structure design of the unlocking groove 12 and the unlocking block 11, then the unlocking block 11 will gradually drive the fastening block 21 to slide out of the fastening groove 22, then the push spring 23 will push the push plate 24 to reset, then the push plate 24 will push one end of the fastening rod 6, through the reaction force of the push spring 23, the fastening sleeve 4 is separated from the outside of the fastening rod 6, then the fastening sleeve 4 is taken off, then the protective frame 27 is taken off, then the filter plate 3 is taken out for maintenance cleaning or replacement, when the filter plate 3 is maintained, cleaned or replaced, first install the filter plate 3 and the protective frame 27 to the original position in sequence, and make the corresponding fastening rod 6 which is connected to the outside of the control box 1 pass through the corresponding mounting hole which is arranged on the protective frame 27, then the fastening sleeve 4 is sleeved to the outside of the fastening rod 6 from one side of the protective frame 27, then one end of the fastening rod 6 abuts against the push plate 24, then make the push plate 24 extrude the push spring 23 again, when the push spring 23 cannot be extruded any more, reverse rotate the rotating sleeve 10, the rotating sleeve 10 will drive the release sleeve 8 to rotate and reset, then through the cooperation of the release block 7 and the release groove 9, the release sleeve 8 is slid to reset, then the release sleeve 8 will drive the unlocking groove 12 which is arranged inside to reset, then the unlocking block 11 moves in the unlocking groove 12 again, then the unlocking block 11 will drive the fastening block 21 to be clamped in the fastening groove 22 again, so that the fastening rod 6 and the fastening sleeve 4 form the clamping relationship again, at the same time, the return spring 26 will drive the locking rod 19 to be inserted into the original locking groove 20, then rotate the rotating plate 14 again, so that the rotating plate 14 drives the arc-shaped groove 15 and the circular groove 16 to move again,When the circular groove 16 moves to the position corresponding to the clamping plate 17, the push spring 25 pushes the locking sleeve 13 to slide and reset, and then the locking sleeve 13 drives the top rod 18 and the clamping plate 17 to slide and reset. When the push spring 25 is completely reset, the rotating plate 14 is rotated again, so that the rotating plate 14 drives the arc-shaped groove 15 and the circular groove 16 to move to a position not corresponding to the top rod 18 and the clamping plate 17. Then the top rod 18 cooperates with the rotating plate 14 to limit the locking sleeve 13, preventing the locking sleeve 13 from sliding. Then the inner wall of the locking sleeve 13 limits the outer end of the locking rod 19 again, preventing the locking rod 19 from moving. Then the locking rod 19 cooperates with the locking groove 20 to stably limit the rotating sleeve 10, preventing the rotating sleeve 10 from rotating, thereby ensuring the stability of the fixation.
[0043] When the device needs to be used, various electrical components are installed on the mounting rack 30 inside the control box 1. The integrated module 28 contains temperature sensors, microcontrollers (MCU) as the core processing unit, power management units, communication interfaces (such as UART, I2C or SPI), memories, relay or transistor switches, LED indicator lights, humidity sensors (optional), and current sensing circuits. To achieve connection and control with the cooling fans 2, the integrated module 28 connects each cooling fan 2 through a relay or transistor switch circuit. The power supply line of the cooling fan 2 is connected to the output end of the switch circuit, while the control line is connected from the MCU to the control end of the switch circuit. The MCU controls each switch circuit through the GPIO port and controls the opening of the cooling fan 2 according to the set temperature threshold. To achieve individual control, independent temperature thresholds can be set for each side of the cooling fan 2. The MCU decides whether to turn on the corresponding cooling fan 2 according to the temperature sensor readings. At the same time, to achieve the function of opening both sides of the cooling fan 2, a higher temperature threshold can be set. When the temperature on either side or both sides exceeds this threshold, the MCU turns on both cooling fans 2. The program written in the MCU regularly reads temperature data and controls the high and low levels of the GPIO port according to the temperature data and the preset threshold, thereby achieving intelligent control of the cooling fan 2. Through this design, the intelligent integrated module 28 can flexibly control the two sides of the cooling fan 2, either individually or simultaneously when necessary, achieving intelligent active temperature management. When the internal temperature rises, the integrated module 28 turns on the cooling fan 2 on the corresponding side. When the left cooling fan 2 is turned on alone, it is in the exhaust mode, and when the right cooling fan 2 is turned on alone, it is in the blowing mode. The integrated module 28 selects the exhaust mode or blowing mode according to different environmental conditions and temperature states. When the internal temperature is slightly higher than the normal working temperature but has not yet reached the critical value, the integrated module 28 turns on the left cooling fan 2 to start the exhaust mode, slowly but continuously reducing the internal temperature. If the temperature continues to rise or reaches the higher threshold, the integrated module 28 turns on the right cooling fan 2 to switch to the blowing mode to cool down more quickly. In some cases, if the temperature rises sharply or has reached a dangerous level, the integrated module 28 turns on both the left and right cooling fans 2 to start the exhaust and blowing modes simultaneously to maximize the cooling effect. In addition, the integrated module 28 may also decide which mode to start based on other environmental factors such as humidity and air quality. For example, in high humidity, the exhaust mode may be preferred to reduce internal humidity, and in poor air quality, the exhaust mode may also be preferred to improve the internal air environment. Through this intelligent control strategy, the integrated module 28 can flexibly adjust the cooling method according to actual needs, ensuring the normal operation of the device and optimizing energy use efficiency.The arrangement of the filter plate 3 can effectively prevent foreign matters from the outside from entering the control box 1 from the air vent, and the arrangement of the protection frame 27 can prevent rainwater from the outside from entering the control box 1 from the filter plate 3.
