Description

Technical Field

[0001] The present application relates to the technical field of power distribution cabinets, and in particular to a power distribution cabinet with temperature control and active heat dissipation function. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits, and the motor control center is used in occasions with concentrated loads and more circuits.

[0003] When the power distribution cabinet is in use, the internal temperature will be very high because there are multiple circuit breakers, relays, speed regulators, PLCs and other electrical components driving it, and the electrical components are neatly arranged in rows. Therefore, a heat dissipation mechanism needs to be provided to dissipate heat inside the control cabinet to prevent the control cabinet from burning out due to excessive temperature. For example, a Chinese patent with publication number CN116828795A in the related technology proposes a PLC control cabinet with temperature-controlled active heat dissipation function, which has the advantage of achieving targeted heat dissipation according to the area where heat dissipation is required through the coordinated use of structures such as a PLC logic controller, a hair dryer, an exhaust fan, and a blowing assembly.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: a smoke sensor is used to sense whether a fire occurs inside the cabinet, and the spraying of dry powder is controlled by the coordinated driving of a controller, a solenoid valve and other structures to extinguish the fire inside the cabinet as a whole. However, the fire extinguishing method of the cabinet in this design is mainly automatically driven by smoke sensors and other controllers. The smoke sensors and intelligent controllers in the prior art cannot be used for a long time. The longer they are used, the lower their performance and sensitivity will be. Therefore, if a controller fails in this design, the fire extinguishing cannot be automatically driven. Moreover, the fire extinguishing of the cabinet in this design is to spray dry powder on the inside of the cabinet in an all-round manner, which results in a large amount of time for subsequent staff to clean the cabinet. Summary of the invention

[0005] In order to solve the problem that the fire extinguishing method of the cabinet is mainly automatically driven by smoke sensors and other controllers, the smoke sensors and intelligent controllers in the prior art cannot be used for a long time. The longer they are used, the lower their performance and sensitivity will be. Therefore, if one controller fails in this design, the fire extinguishing cannot be automatically driven. The present application provides a distribution cabinet with temperature control and active heat dissipation function.

[0006] The present application provides a power distribution cabinet with temperature control and active heat dissipation function, which adopts the following technical solution: A power distribution cabinet with temperature-controlled active heat dissipation function, comprising a PLC power distribution cabinet and three power controllers, a first controller and a second controller fixed inside the PLC power distribution cabinet, the top and bottom of the three power controllers are provided with power lines arranged at equal distances, the top power controller and the bottom power controller are both connected to the middle power controller through the power line, the top power controller is connected to the second controller through the power line, and the bottom power controller is connected to the first controller through the power line, the inside of the PLC power distribution cabinet is provided with a heat dissipation component for dissipating heat for the three power controllers and a ventilation component for ventilating the inside of the PLC power distribution cabinet; A fire extinguishing mechanism for extinguishing a fire on a power controller is provided on the inner side of the PLC power distribution cabinet, the fire extinguishing mechanism comprises a drive box fixed on the left and right sides of the power controller, a drive block fixed on the inner side of the drive box, a dry powder box fixed on the top and bottom of the drive box, a dry powder fire extinguishing agent provided on the inner side of the drive box, a powder discharge head for spraying the dry powder fire extinguishing agent, a pushing member for pushing the dry powder fire extinguishing agent, a trigger member for piercing the drive block, and a discharge member for discharging the dry powder fire extinguishing agent, the powder discharge head is pushed and moved by the pushing member, the drive block is provided on the power controller, the drive block is a soft air bag bag, the drive block will burst when it contacts the flame, and the drive block can bring The PLC power distribution cabinet is driven by an automatic fire extinguishing mechanism and a processing mechanism; a processing mechanism for cutting, pushing and pressing the power line is arranged on the inner side of the PLC power distribution cabinet, and the processing mechanism includes a cutting component, a pushing component and a pressing component; the cutting component includes a ceramic knife for cutting the power line and a pushing member for pushing the ceramic knife to move; the pushing component includes a pushing plate for fixing and arranging a plurality of the power lines and a driving member for pushing the pushing plate; the pressing component includes a movable pressing plate for pressing and fixing the power line and a buffer for providing a buffering force to the movable pressing plate. The front of the PLC power distribution cabinet is movably connected with a power distribution cabinet door, and the inner side of the three power controllers Flame sensors are arranged on the sides of the power distribution cabinet, and an intelligent controller is arranged on the front side of the power distribution cabinet door. The three flame sensors are electrically connected to the intelligent controller, and the trigger can be driven by the intelligent controller; when the flame sensor is used normally and detects a flame, the intelligent controller can be driven to start the trigger to puncture the drive block, so that the fire extinguishing mechanism and the processing mechanism can extinguish the fire of the power controller that is on fire; when the flame sensor is damaged, because the drive block is arranged on the power controller, when the power controller catches fire, the fire will burn the drive block, and the fire extinguishing mechanism and the processing mechanism can also be triggered to extinguish the fire of the power controller that is on fire.

[0007] By adopting the above technical scheme, the heat dissipation mechanism can be used to dissipate heat on the inside of the PLC distribution cabinet, so as to prevent the three power controllers, the first controller and the second controller inside the PLC distribution cabinet from being burned out due to excessive temperature. At the same time, the ventilation component can be used to make the inside of the PLC distribution cabinet have a ventilation effect, which can enhance the heat dissipation efficiency of the three power controllers, the first controller and the second controller in the PLC distribution cabinet, and reduce the probability of short circuit, open circuit and damage to the three power controllers, the first controller and the second controller. The fire extinguishing mechanism can be used to extinguish the fire of the power controller, the discharge piece can make the dry powder fire extinguishing agent spray out from the inside of the dry powder box and the powder outlet head, and extinguish the fire of the power controller, and the push piece can make the dry powder fire extinguishing agent spray out from the dry powder box and the powder outlet head quickly, thereby improving the efficiency of the dry powder fire extinguishing agent in extinguishing the fire of the power controller. The pushing member can drive the powder discharge head to move, so that the powder discharge head can spray the dry powder fire extinguishing agent on the burning power controller in all directions to ensure the fire extinguishing effect of the power controller. There are two ways to drive the rupture of the drive block. First, the flame is detected by the flame sensor, and the flame sensor can transmit the signal to the intelligent controller to drive the trigger member to directly puncture the drive block, and drive the processing mechanism and the fire extinguishing mechanism to extinguish the power controller. However, if the flame sensor fails to detect the flame due to damage, the high-temperature flame of the power controller can also be used to burn the drive block directly. The drive block is set to a soft airbag bag with a low ignition point, which remains solid at around 50 degrees. When it comes into contact with the flame, the drive block will burn with the flame. Therefore, when the power controller catches fire, the processing mechanism and the fire extinguishing process can be driven as the drive block ruptures.

[0008] The processing mechanism can be used to cut, push and press the power line on the burning power controller. The cutting component can cut the power line to block the connection between the burning power controller and other power controllers, the first controller and the second controller, so as to prevent the fire from extending along the power line to other power controllers and causing the fire to increase. The pressing component can press the power line straight to prevent the ceramic knife from affecting the cutting effect of the power line due to being too loose when cutting the power line. At the same time, when the power line is cut, the cut power line can be flattened to prevent the fire source of the power line on the power controller from moving at will, and to prevent the power line from contacting other power lines and causing other fire sources or short circuits. The pushing component can push the other end of the cut power line away from the burning power controller to prevent the power line from causing a larger fire. At the same time, the power line can be fixed and sorted by the push plate. At the same time, the ceramic knife can cut multiple power lines evenly to prevent the other end of the power line from floating at will after being cut off and contacting other power lines to cause sparks. The ceramic knife can avoid the phenomenon of electric induction when cutting the power line, and the ceramic knife can avoid current sparks.

[0010] By adopting the above technical scheme, when the driving block is broken, it will drive the movable push plate to move. Through the connection and cooperation between the movable push plate, the connecting plate and the double-sided rack, the double-sided rack, the two movable gears, the two movable rods and the two connecting protrusions, the two movable push rods and the two push plates can be pushed to move respectively. When the two push plates move, they will push away one end of the power line cut off at the top and bottom of the burning power controller respectively, away from the burning power controller, so as to prevent the power line from causing a larger fire. At the same time, the power line can be fixed and sorted by the push plate to prevent the other end of the power line from floating randomly after being cut off and contacting other power lines to cause sparks. When the movable push plate moves, it will also drive the trigger block to move and fit with the power-off switch, so that the power-off switch can first control the burning power controller to turn off, so as to prevent the intelligent controller from causing a more serious fire due to untimely power off. Therefore, when the driving block is broken, it will also drive the power-off switch to transmit a signal to the intelligent controller, so that the intelligent controller will power off the three power controllers, the first controller and the second controller, and turn off the heat dissipation component and the ventilation component.

[0011] Optionally, the pushing member includes a connecting rack fixed on the outside of the movable pushing rod, the outside of the connecting rack is meshed with a connecting gear, the inside of the connecting gear is provided with a support rod, the outside of the support rod is provided with a movable protrusion, the inside of the dry powder box is movably connected with a pushing plate, the outside of the pushing plate is provided with a telescopic spring, the outside of the pushing plate is provided with a buffer rod, the outside of the buffer rod is provided with an arc plate, the outside of the arc plate is provided with an annular spring, the annular spring is fixedly connected to the dry powder box, and the movable protrusion is movably fitted with the arc plate.

[0013] Optionally, the discharge member includes a movable plate arranged on the inner side of the driving box, two connecting springs are arranged on the outer side of the movable plate, a material blocking plate is arranged on the outer side of the two movable plates, a telescopic tube is arranged on the outer side of the dry powder box, a powder outlet head is arranged on the outer side of the telescopic tube, a limiting block is arranged on the top of the powder outlet head, a connecting block is arranged on the outer side of the limiting block, the connecting block is movably fitted on the outer side of the dry powder box, the ceramic knife is fixed on the outer side of the connecting block, a compression spring is arranged on the outer side of the dry powder box, the compression spring is fixedly connected to the limiting block, the two connecting springs are fixedly connected to the dry powder box, and the movable plate is fixedly connected to the driving block.

[0014] By adopting the above technical solution, when the driving block breaks when encountering fire, it will also drive the pushing part, so that the connecting spring is immediately in a relaxed state, and the movable plate and the material baffle plate can be moved, so that the material baffle plate is separated from the dry powder box and moved to the inside of the driving box, so that the dry powder fire extinguishing agent inside the dry powder box is immediately sprayed out from the telescopic tube and the powder outlet head, and the powder outlet head will spray the dry powder fire extinguishing agent on the burning power controller, so that the power controller can be automatically extinguished.

[0015] Optionally, a limiting slot is opened on the inner side of the connecting block, a limiting square hole is opened on the inner side of the driving box, a fixed square hole is opened on the inner side of the dry powder box, the limiting square hole corresponds to the fixed square hole, the limiting slot and the fixed square hole are movably corresponding to each other, the limiting slot, the limiting square hole and the fixed square hole are all movably fitted with the material baffle plate, two tension springs are arranged on the inner side of the limiting slot, arc blocks are arranged on the outer sides of the two tension springs, two arc grooves are opened on the outer side of the material baffle plate, and the two arc blocks are respectively engaged with the two arc grooves.

[0016] By adopting the above technical scheme, when the baffle plate moves, the tension spring will be in a compressed state, and the arc block and the arc groove will be separated by the elastic force of the connecting spring, and the baffle plate will be separated from the connecting block. At the same time, the compression spring will be in a relaxed state, which in turn drives the limit block, the connecting block, the ceramic knife and the powder outlet head to move left and right. When the powder outlet head moves left and right, the range of fire extinguishing of the power controller by the powder outlet head can be enhanced, and the dry powder fire extinguishing agent can be sprayed on the power controller in all directions, which can enhance the range and effect of fire extinguishing of the power controller by the dry powder fire extinguishing agent.

[0017] Optionally, the buffer component includes a fixed block fixed to the outside of the power controller, a special-shaped spring is provided on the outside of the fixed block, a movable pressure plate is provided on the outside of the special-shaped spring, the movable pressure plate is movably connected to the power controller through a hinge, the fixed block, the special-shaped spring and the movable pressure plate are arranged at equal distances at the top and bottom of the three power controllers, and the multiple movable pressure plates are movably fitted with multiple power lines respectively.

[0018] By adopting the above technical scheme, the power cord can be straightened by the buffer part, and the power cord can be straightened by the cooperation between multiple fixed blocks, multiple special-shaped springs, multiple movable pressure plates and multiple hinges, so as to prevent the ceramic knife from affecting the cutting effect of the power cord due to being too loose when cutting the power cord. At the same time, when the power cord is cut, the elastic force of the special-shaped spring can be used to flatten the cut power cord by the movable pressure plate, so as to prevent the fire source of the power cord on the power controller from moving randomly, and at the same time, it can prevent the power cord from contacting other power cords and causing other fire sources or short circuits.

[0019] Optionally, the heat dissipation component includes a servo motor fixed on the top of the distribution cabinet door, the output shaft of the servo motor is provided with a threaded rod, the outer side of the threaded rod is threadedly connected to a threaded block, the outer side of the threaded block is provided with a limiting block, the outer side of the limiting block is provided with a fixed frame, the inner side of the fixed frame is provided with an electric motor, the output shaft of the electric motor is provided with a driving shaft, the outer side of the driving shaft is provided with a driving wheel, the outer side of the driving wheel is transmission-connected with two transmission belts, the inner sides of the two transmission belts are transmission-connected with driven wheels, the inner sides of the two driven wheels are provided with fan blade rods, the outer sides of the two fan blade rods and the driving shaft are provided with movable blades, and the servo motor and the electric motor are electrically connected to the intelligent controller.

[0020] By adopting the above technical scheme, the motor can drive the driving shaft, the driving wheel, the two driven wheels, the two transmission belts, the two driven wheels, the two fan blade rods and the three movable blades to rotate in sequence. When the three movable blades rotate, wind will be generated and blown on the power controller, so that the power controller can be cooled. At the same time, the servo motor can drive the threaded rod to rotate, and then the threaded block, the fixed frame, the motor and the three movable blades can be driven to move up and down in sequence. The positions of the three movable blades can be adjusted, and the three movable blades can be moved to the front of the three power controllers in sequence to enhance the heat dissipation effect of the current corresponding power controllers. At the same time, when the intelligent controller receives a signal that there is a fire in the PLC distribution cabinet, it will drive the servo motor and the motor to stop driving to prevent the wind from aggravating the fire in the PLC distribution cabinet. At the same time, when the three movable blades continue to dissipate heat and cool down the three power controllers, the temperature of the three power controllers can be continuously controlled below 20 degrees, so that the drive block on the power controller can be prevented from being broken and driven due to the influence of the temperature of the power controller.

[0021] Optionally, the trigger member includes a power spring fixed on the inner side of the power controller, a needle plate is provided at the bottom end of the power spring, an electromagnet is provided on the inner side of the power controller, an iron block is provided on the top of the needle plate, the electromagnet is magnetically connected to the iron block, the needle plate is movably fitted to the drive block, and the electromagnet is electrically connected to the intelligent controller.

[0022] By adopting the above technical solution, flame sensors are set on the three power controllers to detect whether there is a fire on the power controller. When one of the power controllers catches fire, the flame sensor on the burning power controller will be triggered, and the flame sensor will transmit the signal to the intelligent controller. The intelligent controller can control the electromagnet on the burning power controller to stop driving so that the iron block loses its limit. The elastic force of the power spring can drive the needle plate and the iron block to move downward in turn. The impact force of the downward movement of the needle plate can pierce the driving block. The rupture of the driving block can also directly drive the fire extinguishing mechanism and the processing mechanism through the above principle to extinguish the fire and disconnect the designated burning power controller.

[0023] Optionally, the ventilation assembly includes a first bevel gear fixed to the outside of the threaded rod, a second bevel gear meshing with the outside of the first bevel gear, a movable shaft is provided on the inside of the second bevel gear, a reverse blade is provided on the outside of the movable shaft, a heat dissipation frame is provided on the outside of the distribution cabinet door, a filter plate is movably connected to the outside of the heat dissipation frame, the reverse blade is located on the inside of the heat dissipation frame, an air intake pipe is provided on the inside of the heat dissipation frame, a ventilation hood is provided on the outside of the ventilation hood, a solenoid valve is fixedly installed on the outside of the ventilation hood, the inlet of the air intake pipe is located on the inside of the ventilation hood, and the solenoid valve is electrically connected to the intelligent controller.

[0024] By adopting the above technical scheme, when the servo motor drives the threaded rod to rotate, it will also drive the first bevel gear, the second bevel gear, the movable shaft and the reverse blade to rotate in turn to generate suction, so that the gas inside the PLC distribution cabinet can be sucked into the heat dissipation frame through the ventilation hood and the air inlet pipe, and then released through the filter plate, so that the inside of the PLC distribution cabinet can be ventilated and the heat dissipation effect of the three power controllers, the first controller and the second controller inside the PLC distribution cabinet can be enhanced. At the same time, the filter plate can make the heat dissipation frame have a dust-proof effect to prevent dust and particles from entering the inside of the heat dissipation frame to ensure the hygiene of the reverse blade. When the ventilation hood is ventilated, the solenoid valve is always in the open state. When the intelligent controller receives a signal that the inside of the PLC distribution cabinet is on fire, it will drive the solenoid valve to close the ventilation hood, so that the inside of the PLC distribution cabinet is in a vacuum state and the internal pressure will be reduced. The powder discharge head sprays dry powder fire extinguishing agent on the burning power controller to diffuse it, thereby improving the scope and effect of fire extinguishing of the power controller.

[0025] Optionally, a collection module is provided on the top of the PLC distribution cabinet, an alarm is provided on the top of the PLC distribution cabinet, a monitor and a smoke sensor are provided on the inner top wall of the PLC distribution cabinet, three temperature detectors are provided on the back of the PLC distribution cabinet, temperature detection rods are provided on the outer sides of the three temperature detectors, the three temperature detection rods are respectively fitted with three power controllers, and the three temperature detectors, collection modules, alarms, monitors, and smoke sensors are all electrically connected to the intelligent controller.

[0026] By adopting the above technical solution, the smoke sensor can detect whether there is smoke inside the PLC distribution cabinet. When there is smoke inside the PLC distribution cabinet, the smoke sensor will transmit a signal to the intelligent controller, and the intelligent controller can control the three power controllers, the first controller, the second controller, the heat dissipation component and the ventilation component to be turned off. The three power controllers, the first controller and the second controller are turned off to prevent leakage and cause more serious fires. The temperatures of the three power controllers can be detected respectively by three temperature detectors and three temperature detection rods. The three temperature detectors will transmit the detected temperatures to the intelligent controller respectively, and the intelligent controller will compare them with the optimal suitable temperature of the power controller. When the intelligent controller detects that the temperature of one of the temperature detectors exceeds the optimal set temperature, the speed of the motor can be controlled by the intelligent controller, the timing start of the motor and the servo motor can be controlled, the three movable blades can be moved to the front of the specified power controller, and the speed of the three movable blades can be increased to enhance the heat dissipation effect of the current corresponding power controller.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. Flame sensors are set on the three power controllers to detect whether there is a fire on the power controller. When one of the power controllers catches fire, the flame sensor on the burning power controller will be triggered, and then the flame sensor will transmit the signal to the intelligent controller. The intelligent controller can control the two electromagnets on the burning power controller to stop driving. At this time, the iron block will lose its limit, and the elastic force of the power spring can drive the needle plate and the iron block to move downward in turn. The impact force of the needle plate moving downward can pierce the drive block, so that the rupture of the drive block can directly The fire extinguishing mechanism and the processing mechanism are driven to extinguish the fire and disconnect the designated power controller that is on fire. At the same time, the intelligent controller will immediately control the three power controllers, the first controller, the second controller, the heat dissipation component and the ventilation component to be closed, so that the inside of the PLC power distribution cabinet is in a vacuum state and the internal pressure will be reduced. The powder discharge head sprays dry powder fire extinguishing agent on the burning power controller, which can spread the dry powder fire extinguishing agent and spray the dry powder fire extinguishing agent on the burning power controller in a full range, which can assist the fire extinguishing mechanism and the processing mechanism to extinguish the fire and disconnect the burning power controller; 2. When one of the power controllers catches fire, and the flame sensor and the smoke sensor do not drive and trigger the intelligent controller to shut down the three power controllers, the first controller, the second controller, the heat dissipation component and the ventilation component, and the electromagnet is not triggered to close the driving trigger, the fire extinguishing mechanism and the processing mechanism can also be triggered to extinguish the burning power controller. Because the drive block is set on the power controller, when the power controller catches fire, the high temperature will burn the drive block, and the connecting spring will be immediately in a relaxed state, so that the movable plate and the baffle plate will move, and the tension spring will be in a compressed state at this time, and the arc block will be separated from the arc groove by the elastic force of the connecting spring. The baffle plate is separated from the connecting block and the dry powder box, and the dry powder fire extinguishing agent in the dry powder box is immediately sprayed from the telescopic tube and the powder outlet head on the power controller to extinguish the fire. When the baffle plate is separated from the connecting block, the compression spring is in a relaxed state, which in turn drives the limit block, the connecting block, the ceramic knife and the powder outlet head to move left and right, thereby increasing the range of the powder outlet head to extinguish the fire on the power controller, and the dry powder fire extinguishing agent can be sprayed on the power controller in an all-round manner, thereby increasing the range and effect of the dry powder fire extinguishing agent on the power controller. When the ceramic knife moves left and right, the power line on the current burning power controller can be cut to prevent the fire from spreading along the power line to other power controllers and causing the fire to increase. 3. Through the cooperation between the fixed block, the special-shaped spring, the movable pressure plate and the hinge, the power cord can be pressed straight to prevent the ceramic knife from cutting the power cord due to being too loose and affecting the cutting effect of the power cord. At the same time, when the power cord is cut, the elastic force of the special-shaped spring can be used to flatten the cut power cord to prevent the power cord on the power controller from moving at will, and to prevent the power cord from contacting other power cords and causing other fire sources or short circuits. At the same time, when the drive block is broken, the spiral spring will also be in a relaxed state, which will drive the active The movable push plate moves, and then through the cooperation of the movable push plate, the connecting plate, the double-sided rack, the two movable gears, the two movable rods and the two connecting protrusions, the two movable push rods and the two push plates can be pushed to move respectively. Because the power cords at the top and bottom of the power controller are cut off by the ceramic knife, when the two push plates move, they will push the other ends of the cut power cords away from the burning power controller to prevent the power cords from igniting and causing a larger fire. At the same time, the power cords can be fixed and sorted through the push plates to prevent the other ends of the power cords from being cut. After being cut off, it floats randomly and contacts other power lines to cause sparks. When moving through two push-wire plates, the arc plate will be squeezed through the connection and cooperation of the connecting rack, two connecting gears, two support rods and two movable protrusions. With the elastic force of the telescopic spring and the annular spring, the buffer rod and the push plate can be driven to move in turn, and the dry powder fire extinguishing agent in the dry powder box can be pushed, and the dry powder fire extinguishing agent in the dry powder box can be quickly pushed out from the powder outlet head, which can increase the speed of the dry powder fire extinguishing agent to extinguish the fire of the power controller. When a power controller catches fire, the dry powder fire extinguishing agent can be sprayed on the burning power controller alone to extinguish the fire. When the power controller catches fire, even if the smoke sensor and the flame sensor are damaged, the fire can be automatically extinguished. There is no need to spray the dry powder fire extinguishing agent on the inside of the entire PLC distribution cabinet, so as to facilitate the subsequent staff to clean up. At the same time, when a power controller catches fire, the connection relationship between the burning power controller and other power controllers, the first controller and the second controller can be immediately blocked to prevent the burning power controller from igniting other normal power controllers, the first controller and the second controller.

Moreover, when a power controller 2 catches fire, a dry powder fire extinguishing agent can be sprayed on the burning power controller 2 alone for fire extinguishing treatment, and there is no need to spray dry powder fire extinguishing agent on the inside of the entire PLC distribution cabinet 1, so as to facilitate subsequent cleaning by subsequent staff. The wire push plate 19 and multiple wire management holes are used to organize multiple power cords 3 to avoid the risk of short circuit caused by the multiple power cords 3 being tangled together.

[0042] The implementation principle of a power distribution cabinet with temperature control and active heat dissipation function in the embodiment of the present application is as follows: (1) The motor 51 can sequentially drive the driving shaft 52 and the driving wheel 53 to rotate. When the driving wheel 53 rotates, it will respectively drive the two transmission belts 54, the two driven wheels 55 and the two blade rods 56 to rotate. When the two blade rods 56 and the driving shaft 52 rotate, they will drive the three movable blades 57 to rotate. When the three movable blades 57 rotate, wind will be generated and blown onto the power controller 2, thereby heat dissipating the power controller 2. (2) The threaded rod 47 can be driven to rotate by the servo motor 46. When the threaded rod 47 rotates, it will sequentially drive the threaded block 48, the limit block 49, the fixed frame 50, the motor 51, the drive shaft 52, the two fan blade rods 56 and the three movable blades 57 to move up and down. The positions of the three movable blades 57 can be adjusted. The three movable blades 57 can be moved to the front of the three power controllers 2 in turn to enhance the heat dissipation effect of the current corresponding power controller 2; (3) The temperatures of the three power controllers 2 can be detected respectively by three temperature detectors 44 and three temperature detection rods 45. The three temperature detectors 44 transmit the detected temperatures to the intelligent controller 9 respectively. The intelligent controller 9 compares the detected temperatures with the optimal suitable temperatures of the power controller 2. When the intelligent controller 9 detects that the temperature of one of the temperature detectors 44 exceeds the optimal set temperature, the intelligent controller 9 can control the speed of the motor 51 and control the timing of starting the motor 51 and the servo motor 46. The three movable blades 57 can be moved to the front of the designated power controller 2, and the speed of the three movable blades 57 can be increased to enhance the heat dissipation effect of the current corresponding power controller 2. (4) At the same time, when the threaded rod 47 rotates, it drives the first bevel gear 61 to rotate. When the first bevel gear 61 rotates, it drives the second bevel gear 62, the movable shaft 63 and the reverse blade 64 to rotate in turn. When the reverse blade 64 rotates, suction is generated, so that the gas inside the PLC distribution cabinet 1 can be sucked into the inner side of the heat dissipation frame 58 through the twelve air inlet pipes 60, and then released through the filter holes in the filter plate 59, so that the inside of the PLC distribution cabinet 1 can be ventilated and the heat dissipation effect of the three power controllers 2, the first controller 4 and the second controller 5 inside the PLC distribution cabinet 1 can be enhanced. At the same time, by setting the filter plate 59, The heat dissipation frame 58 has a dustproof effect, which prevents dust and particles from entering the inner side of the heat dissipation frame 58 to ensure the hygiene of the reverse blade 64. The four connecting screws can ensure the stability of the connection between the filter plate 59 and the heat dissipation frame 58, which prevents the filter plate 59 from falling off during use. At the same time, the filter plate 59 can be disassembled to facilitate regular cleaning or washing of the filter plate 59. When the three movable blades 57 continuously dissipate heat and cool the three power controllers 2, the temperature of the three power controllers 2 can be continuously controlled to be below 20 degrees, which can prevent the driving block 11 on the power controller 2 from being driven by the temperature of the power controller 2. (5) When one of the power controllers 2 catches fire, and the flame sensor 78 and the smoke sensor 71 become unstable due to long-term use, and the intelligent controller 9 is not triggered to shut down the three power controllers 2, the first controller 4, the second controller 5, the heat dissipation component and the ventilation component, and the electromagnet 76 is not triggered to shut down the driving trigger, the fire extinguishing mechanism and the processing mechanism can also be triggered to extinguish the fire of the power controller 2 that is on fire, because the driving block 11 is set on the power controller 2, and when the power controller 2 catches fire, the high temperature will drive the driving block 11 to the power controller 2. The movable block 11 burns, so that the connecting spring 32 is immediately in a relaxed state, and the movable plate 31 and the material blocking plate 33 can be moved. At this time, the tension spring 66 is in a compressed state, and the arc block 67 is separated from the arc groove by the elastic force of the connecting spring 32, and the material blocking plate 33 is separated from the connecting block 34 and the dry powder box 28, so that the dry powder fire extinguishing agent inside the dry powder box 28 is immediately sprayed out from the telescopic tube 38 and the powder outlet head 39, and the powder outlet head 39 sprays the dry powder fire extinguishing agent on the power controller 2, so that the power controller 2 can be extinguished; (6) At the same time, when the baffle plate 33 is separated from the connecting block 34, the compression spring 36 is in a relaxed state, thereby driving the limit block 37, the connecting block 34, the ceramic knife 35 and the powder outlet head 39 to move left and right in sequence. When the powder outlet head 39 moves left and right, the range of fire extinguishing of the power controller 2 by the powder outlet head 39 can be enhanced, and the dry powder fire extinguishing agent can be sprayed on the power controller 2 in all directions, which can enhance the range and effect of the dry powder fire extinguishing agent on the power controller 2. (7) When the ceramic knife 35 is moved left and right at the same time, the power line 3 on the power controller 2 that is currently on fire can be cut to prevent the fire from spreading along the power line 3 to other power controllers 2 and causing the fire to spread; (8) The coordination between the driving block 11, the movable plate 31, the connecting spring 32, the material blocking plate 33, the tension spring 66 and the arc block 67 can ensure the positioning effect of the connecting block 34. When the power controller 2 is not on fire, the connecting block 34 can be stably installed on the dry powder box 28; (9) Through the cooperation between the fixed block 68, the special-shaped spring 69, the movable pressure plate 70 and the hinge, the power cord 3 can be pressed straight to prevent the ceramic knife 35 from affecting the cutting effect of the power cord 3 due to being too loose when cutting the power cord 3. At the same time, when the power cord 3 is cut, the elastic force of the special-shaped spring 69 can be used to flatten the cut power cord 3 by the movable pressure plate 70 to prevent the power cord 3 on the power controller 2 from moving randomly. At the same time, it can prevent the power cord 3 from contacting other power cords 3 and causing other fire sources or short circuits; (10) At the same time, when the driving block 11 breaks, the coil spring 41 will also be in a relaxed state, and then it will drive the movable push plate 12, the connecting plate 13 and the double-sided rack 14 to move left and right in turn. When the double-sided rack 14 moves left and right, it will respectively drive the two movable gears 15, the two movable rods 16 and the two connecting protrusions 17 to rotate. When the two connecting protrusions 17 rotate, they will respectively push the two movable push rods 18 and the two push plates 19 to move. Because the power cord 3 at the top and bottom of the power controller 2 is cut off by the ceramic knife 35, when the two push plates 19 move, they will push the other end of the power cord 3 that has been cut off away from the burning power controller 2 to prevent the power cord 3 from igniting and causing a larger fire. At the same time, the power cord 3 can be fixed and sorted by the push plate 19 to prevent the other end of the power cord 3 from floating randomly after being cut off and contacting other power cords 3 to cause sparks; (11) When the movable push plate 12 moves left and right, it will also drive the trigger block 79 to move and then fit with the power-off switch 80, so that the power-off switch 80 can first control the burning power controller 2 to be turned off, so as to prevent the intelligent controller 9 from causing a more serious fire due to untimely power off. At the same time, the signal will be transmitted to the intelligent controller 9, so that the intelligent controller 9 can turn off the solenoid valve 73, the servo motor 46 and the motor 51, so that the ventilation component and the heat dissipation component stop driving, so that the inside of the PLC distribution cabinet 1 is in a vacuum state, thereby assisting the fire extinguishing mechanism and the processing mechanism to extinguish the burning power controller 2. At the same time, the intelligent controller 9 can control the three power controllers 2, the first controller 4 and the second controller 5 of the PLC distribution cabinet 1 to stop driving to avoid causing an electric current fire, and the intelligent controller 9 can trigger the alarm 7 to alarm, reminding the staff to come for maintenance; (12) When the two pusher plates 19 move, the two connecting racks 20 are also driven to move. When the connecting racks 20 move, the two connecting gears 21, the two support rods 22 and the two movable protrusions 23 are driven to rotate in a circle. When the two movable protrusions 23 rotate in a circle, they squeeze the arc plate 24, and then cooperate with the elastic force of the telescopic spring 27 and the annular spring 29 to drive the buffer rod 25 and the agent pusher plate 26 to move in turn. When the agent pusher plate 26 moves, it can push the dry powder fire extinguishing agent inside the dry powder box 28, and then the dry powder fire extinguishing agent inside the dry powder box 28 can be quickly pushed out from the powder outlet 39, which can increase the speed of the dry powder fire extinguishing agent to extinguish the fire on the power controller 2; (13) At the same time, when one of the power controllers 2 catches fire, and the flame sensor 78 and the smoke sensor 71 can be used normally, the flame sensor 78 on the power controller 2 that is on fire will be triggered, and the flame sensor 78 will transmit a signal to the intelligent controller 9. The intelligent controller 9 can control the two electromagnets 76 on the power controller 2 that is on fire to stop driving. At this time, the iron block 77 will lose its limit, and the elastic force of the power spring 74 can drive the needle plate 75 and the iron block 77 to move downward in turn. The impact force of the needle plate 75 moving downward can pierce the drive block 11, so that through the rupture of the drive block 11, the fire extinguisher can also be directly driven according to the above principle. The fire mechanism and the processing mechanism perform fire extinguishing and disconnection processing on the designated power controller 2 that is on fire. At the same time, the intelligent controller 9 will immediately control the three power controllers 2, the first controller 4, the second controller 5, the heat dissipation component and the ventilation component to be closed, so that the inside of the PLC distribution cabinet 1 is in a vacuum state and the internal pressure will be reduced. The powder discharge head 39 sprays dry powder fire extinguishing agent on the burning power controller 2, which can diffuse the dry powder fire extinguishing agent and spray the dry powder fire extinguishing agent on the burning power controller 2 in a full range, thereby increasing the scope and effect of fire extinguishing of the power controller 2, and assisting the fire extinguishing mechanism and the processing mechanism to extinguish and disconnect the burning power controller 2; (14) The situation inside the PLC distribution cabinet 1 can be monitored by the monitor 65. Flame sensors 78 are set on the three power controllers 2 to detect whether there is a fire on the power controller 2. When a fire occurs inside the PLC distribution cabinet 1 and needs to be extinguished or other accidents occur, the monitor 65 will transmit the monitored situation to the intelligent controller 9, and the intelligent controller 9 will transmit the signal to the alarm 7 and the acquisition module 6. The alarm 7 will sound an alarm to remind the surrounding staff to pay attention to safety and handle the situation. At the same time, the acquisition module 6 will send the situation to a remote communication device to remind the remote staff to handle the situation and provide double insurance; (15) By arranging two fire extinguishing mechanisms and two processing mechanisms on the left and right sides of the three power controllers 2, the efficiency and effect of fire extinguishing of each power controller 2 can be ensured, and at the same time, the efficiency of blocking the burning power controller 2 from other power controllers 2, the first controller 4 and the second controller 5 can be ensured. Moreover, when a power controller 2 catches fire, dry powder fire extinguishing agent can be sprayed on the burning power controller 2 alone to extinguish the fire, and there is no need to spray dry powder fire extinguishing agent on the inside of the entire PLC distribution cabinet 1, so as to facilitate subsequent cleaning by subsequent staff. At the same time, when a power controller 2 catches fire, the connection relationship between the burning power controller 2 and other power controllers 2, the first controller 4 and the second controller 5 can be immediately blocked to prevent the burning power controller 2 from igniting other normal power controllers 2, the first controller 4 and the second controller 5.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
