Description
Technical Field
[0001] This invention relates to the field of distribution box technology, and more specifically to a distribution box suitable for low-carbon smart grids. Background Technology
[0002] Distribution boxes are divided into power distribution cabinets, lighting distribution boxes, and metering boxes. They are the final-level equipment in a power distribution system. Distribution boxes are a general term for motor control centers. Distribution boxes are used in situations where the load is relatively dispersed and there are fewer circuits. Motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a certain circuit of the previous level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load. In response to the current situation where single-point failures are prone to occur in the power distribution of computer rooms, this product integrates the most advanced technological achievements and hardware and software design, and is committed to bringing a brand-new experience to the construction and management of power distribution in computer rooms. It is mainly used in data centers and computer rooms in finance, telecommunications, enterprises, and government.
[0003] In existing technology, distribution boxes typically house a large number of electrical devices and undergo regular maintenance. However, after prolonged use, these devices may become damaged due to aging. This aging equipment can then lead to short circuits or fires, potentially damaging other working electrical equipment and increasing overall losses, thus affecting the distribution box's performance. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a distribution box suitable for low-carbon smart grids, thereby solving the problems mentioned in the background section.
[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A distribution box suitable for low-carbon smart grids includes a box body, a door rotatably connected to one side of the box body, a PLC controller fixedly installed on one side of the inside of the box body, a short-circuit grounding indicator fixedly installed on one side of the inside of the box body, the PLC controller and the short-circuit grounding indicator being electrically connected, and a miniature air compressor fixedly installed on the bottom surface of the inside of the box body, the miniature air compressor being electrically connected to the PLC controller; Several multi-way solenoid valves are fixedly installed on one side of the interior of the housing. The multi-way solenoid valves are electrically connected to the PLC controller. Several mounting brackets are provided inside the housing. Current sensors are fixedly installed on the bottom surface of the mounting brackets. Several guide rails are fixedly installed on one side of the interior of the housing. The mounting brackets are slidably connected to the guide rails. Several first pneumatic push rods are fixedly installed on one side of the interior of the housing. One end of the telescopic rod of the first pneumatic push rod is fixedly installed to the mounting bracket. A mounting base is provided on one side of the mounting bracket. A flame sensor is fixedly installed inside the mounting base. The flame sensor is electrically connected to the PLC controller. An adjusting plate is rotatably connected inside the housing. Arc-shaped sliding grooves are respectively opened on both sides of the inside of the housing. The arc-shaped sliding grooves are slidably connected to the adjusting plate. Several pressure frames are slidably connected inside the adjusting plate. Several second pneumatic push rods are fixedly installed on one side of the adjusting plate. The top surface of the telescopic rod of the second pneumatic push rod is fixedly installed to the pressure frame. The first pneumatic push rod and the second pneumatic push rod are connected to the multi-way solenoid valve through a hose. The multi-way solenoid valve is connected to the exhaust port of the micro air compressor through a hose. An installation plate is fixedly installed inside the door. Several first electromagnets are fixedly installed on one side of the installation plate, and several second electromagnets are fixedly installed on another side of the installation plate. Both the first and second electromagnets are electrically connected to the PLC controller. Several lower covers are provided on one side of the installation plate. An upper cover is rotatably connected to the top surface of the lower cover. A tension spring is fixedly installed inside the lower cover, and one end of the tension spring is fixedly installed to the upper cover.
[0006] By adopting the above technical solution, electrical equipment can be installed inside the enclosure using multiple mounting brackets. The electrical equipment is then connected to the current sensor via wires. When a short circuit occurs in the electrical equipment, the current sensor sends an electrical signal to the short-circuit grounding indicator. The short-circuit grounding indicator processes the signal and sends it back to the PLC controller. The PLC controller then determines the location of the short-circuited electrical equipment. When personnel open the PLC controller to inspect the electrical equipment, they can accurately locate the faulty equipment. At this point, the PLC controller controls the micro air compressor to activate the first pneumatic push rod, thereby activating the first pneumatic push rod. The extension of the telescopic rod of the push rod moves the mounting bracket and electrical equipment, allowing personnel to inspect the equipment independently. Simultaneously, the movement of the faulty electrical equipment isolates it from other electrical equipment inside the enclosure, preventing interference with the inspection work. When electrical equipment inside the enclosure catches fire due to aging, the flame sensor detects the fire and sends an electrical signal to the PLC controller. The PLC controller then activates the micro air compressor, causing the extension rods of the second and first pneumatic push rods to move. The retraction of the second pneumatic push rod then moves the corresponding... The pressure frame slides downwards, and then the bottom of the pressure frame presses down on the wiring connection of the electrical equipment. At the same time, the extension rod of the first pneumatic push rod extends and moves the mounting frame and the burning electrical equipment out of the pile of electrical equipment. At this time, because the connecting wires of the electrical equipment are limited and fixed by the pressure frame, the wires of the electrical equipment will separate from it during its movement, thereby cutting off the power to the electrical equipment. At this time, the electrical equipment moved by the first pneumatic push rod will enter the interior of the upper and lower covers. When the electrical equipment comes into contact with the pressure sensor, the pressure sensor will feed back an electrical signal to the PLC controller. Then the PLC controller controls the first pneumatic push rod corresponding to the position of the pressure sensor. When one electromagnet is de-energized, the upper cover, which was attracted by the first electromagnet, releases its attraction and limiting effect. Then, under the elastic tension of the tension spring, the upper cover closes to the side of the lower cover, enclosing the burning electrical equipment inside the upper and lower covers. Subsequently, the PLC controller de-energizes the corresponding second electromagnet, at which point the upper and lower covers can be separated from the side of the mounting plate. This facilitates real-time short-circuit monitoring of the electrical equipment inside the enclosure and allows for detachment and protective isolation when the electrical equipment catches fire due to aging. This prevents the fire of aging electrical equipment from causing damage to other electrical equipment inside the enclosure.

The limiting block is movably sleeved with the inner circular wall of the limiting groove.
[0010] By adopting the above technical solution, when installing electrical equipment, the worker can rotate the adjusting plate, which will cause the limiting block to move out of the limiting groove and move to the position of the next limiting groove. Then, the rebound force of the first spring will cause the limiting block to re-enter the limiting groove, thereby limiting and fixing the adjusting plate. This allows the position of the adjusting plate to be adjusted and fixed during the installation of electrical equipment, preventing the adjusting plate from affecting the installation of electrical equipment and the distribution of wires.
[0011] Preferably, a plurality of adjusting screws are fixedly installed on one side of the inner side of the housing, and a plurality of guide rods are fixedly installed on one side of the inner side of the housing.

The inner circular wall surface of the threaded sleeve is threadedly connected to the adjusting screw. A guide tube is fixedly installed on one side of the mounting base. The inner circular wall surface of the guide tube is slidably connected to the guide rod.
[0012] By adopting the above technical solution, after the electrical equipment is installed, the staff can rotate the corresponding threaded sleeve according to the size of the electrical equipment. Then, under the thread transmission of the threaded sleeve, the mounting base will move together with the flame sensor. In this way, the usage position of multiple flame sensors can be adjusted individually to adapt to electrical equipment of different sizes.
[0013] Preferably, a fire extinguishing bag is fixedly installed on one side of the upper cover, and a number of piercing nails are fixedly installed on one side of the lower cover.
[0014] By adopting the above technical solution, when the burning electrical equipment enters the upper and lower enclosures, the upper and lower enclosures close together, causing multiple piercing nails to puncture the fire extinguishing bag inside the upper enclosure. The fire extinguishing agent inside the fire extinguishing bag will then actively extinguish the fire on the electrical equipment, thereby preventing the electrical equipment inside the upper and lower enclosures from continuing to burn and causing potential dangers.
[0015] Preferably, a heat sink is fixedly installed on one side of the inside of the housing, and a plurality of cooling fans are fixedly installed inside the heat sink. The cooling fans are electrically connected to the PLC controller.

[0016] By adopting the above technical solution, multiple cooling fans can actively dissipate heat from the inside of the enclosure, and a filter screen can block and filter dust and impurities. At the same time, the filter screen can be quickly installed and removed by being fixed by strong magnets.
[0017] Preferably, a temperature and humidity sensor is fixedly installed on one side of the interior of the housing, and the temperature and humidity sensor is electrically connected to the PLC controller.

At the same time, the sealing fit of the sealing ring and the frame can prevent water from entering the protective cover and affecting its use.
[0021] In summary, the present invention has the following main beneficial effects: 1. Upon detecting a fire, the system uses a second pneumatic push rod to press down on the wire connection point to forcibly cut off the power. Simultaneously, the first pneumatic push rod moves the equipment into a sealed compartment composed of upper and lower covers, and triggers a piercing nail to puncture the fire extinguishing bag for fire suppression. This achieves an integrated operation of automatic power cut-off, removal, sealing and isolation, and active fire suppression for the burning equipment, effectively curbing the spread of fire and greatly improving safety.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 and Figure 10A distribution box suitable for low-carbon smart grids includes: a box body 1, a box door 2 rotatably connected to one side of the box body 1, a PLC controller 8 fixedly installed on one side of the box body 1, a short-circuit grounding indicator 9 fixedly installed on one side of the box body 1, the PLC controller 8 and the short-circuit grounding indicator 9 being electrically connected, a miniature air compressor 14 fixedly installed on the bottom surface of the box body 1, the miniature air compressor 14 being electrically connected to the PLC controller 8; several multi-way solenoid valves 17 fixedly installed on one side of the box body 1, the multi-way solenoid valves 17 being electrically connected to the PLC controller 8, several mounting brackets 10 provided inside the box body 1, current sensors 50 fixedly installed on the bottom surface of the mounting brackets 10, several guide rails 24 fixedly installed on one side of the box body 1, the mounting brackets 10 being slidably connected to the guide rails 24, and several... A first pneumatic push rod 21 is installed, with one end of its telescopic rod fixedly mounted to a mounting bracket 10. A mounting base 16 is provided on one side of the mounting bracket 10, and a flame sensor 33 is fixedly mounted inside the mounting base 16. The flame sensor 33 is electrically connected to the PLC controller 8. An adjusting plate 20 is rotatably connected inside the housing 1. Arc-shaped sliding grooves 18 are respectively opened on both sides of the inside of the housing 1. The arc-shaped sliding grooves 18 are slidably connected to the adjusting plate 20. Several pressure frames 22 are slidably connected inside the adjusting plate 20. Several second pneumatic push rods 23 are fixedly mounted on one side of the adjusting plate 20. The top surface of the telescopic rod of the second pneumatic push rod 23 is fixedly mounted to the pressure frame 22. The first pneumatic push rod 21 and the second pneumatic push rod 23 are connected to a multi-way solenoid valve 17 through a hose. The multi-way solenoid valve 17 is connected to the exhaust port of a micro air compressor 14 through a hose.An installation plate 38 is fixedly installed inside the enclosure door 2. Several first electromagnets 39 are fixedly installed on one side of the installation plate 38, and several second electromagnets 40 are fixedly installed on the other side. Both the first electromagnets 39 and the second electromagnets 40 are electrically connected to the PLC controller 8. Several lower cover 42s are provided on one side of the installation plate 38. An upper cover 41 is rotatably connected to the top surface of the lower cover 42. A tension spring 43 is fixedly installed inside the lower cover 42, and one end of the tension spring 43 is fixedly installed to the upper cover 41. Electrical equipment can be installed inside the enclosure 1 through multiple mounting brackets 10. The electrical equipment is then connected to the current sensor 50 via a wire. When a short circuit occurs in the electrical equipment, the current sensor 50 sends an electrical signal back to the short-circuit grounding indicator 9. The short-circuit grounding indicator 9 processes the signal and sends it back to the PLC controller 8. The PLC controller 8 then determines the location of the short-circuited electrical equipment. When the operator opens the PLC controller 8 to inspect the electrical equipment, they can accurately determine the location of the faulty equipment. At this time, the PLC controller 8 controls the micro air compressor 14 to start the first pneumatic push rod. 21. Subsequently, the extension of the telescopic rod of the first pneumatic push rod 21 will drive the mounting bracket 10 and electrical equipment to move, allowing the operator to perform maintenance on the electrical equipment independently. Simultaneously, the movement of the faulty electrical equipment separates it from other electrical equipment inside the housing 1, preventing interference with the operator's maintenance work. When the electrical equipment inside the housing 1 catches fire due to aging, the flame sensor 33 will detect the burning equipment and send an electrical signal to the PLC controller 8. The PLC controller 8 then controls the activation of the micro air compressor. Pump 14, at this time, the telescopic rods of the second pneumatic push rod 23 and the first pneumatic push rod 21 will move, and then the telescopic rod of the second pneumatic push rod 23 will retract and drive the corresponding pressure frame 22 to slide downward. Then the bottom of the pressure frame 22 will press down on the wire connection of the electrical equipment. At the same time, the telescopic rod of the first pneumatic push rod 21 will extend and move the mounting frame 10 and the burning electrical equipment out of the electrical equipment group. At this time, since the connecting wires of the electrical equipment are limited and fixed by the pressure frame 22, the wires of the electrical equipment will be separated from it during its movement, thereby cutting off the power to the electrical equipment.At this time, the electrical equipment moved by the first pneumatic push rod 21 will enter the interior of the upper cover 41 and the lower cover 42. When the electrical equipment comes into contact with the pressure sensor 46, the pressure sensor 46 will feed back an electrical signal to the PLC controller 8. Then, the PLC controller 8 controls the first electromagnet 39 corresponding to the position of the pressure sensor 46 to de-energize. At this time, the upper cover 41 attracted by the first electromagnet 39 will release its attraction and limiting effect. Then, under the elastic tension of the tension spring 43, the upper cover 41 will close to the side of the lower cover 42, and the burning electrical equipment will be wrapped inside the upper cover 41 and the lower cover 42. Then, the PLC controller 8 de-energizes the corresponding second electromagnet 40. At this time, the upper cover 41 and the lower cover 42 can be separated from the side of the mounting plate 38. This achieves the effect of facilitating real-time short-circuit monitoring of the electrical equipment inside the enclosure 1, and at the same time, facilitating the removal and protective isolation of the electrical equipment when it catches fire due to aging. This can prevent the aging electrical equipment from catching fire and causing damage to other electrical equipment inside the enclosure 1. ;
[0031] Based on the above embodiments, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10A limiting frame 15 is fixedly installed on one side of the interior of the enclosure 1. A wiring plate 25 is fixedly installed on the bottom surface of the interior of the limiting frame 15. Several positioning plates 29 are fixedly installed on one side of the interior of the limiting frame 15, with two positioning plates 29 forming a group. Two clamping blocks 30 are arranged between each group of positioning plates 29. A limiting post 31 is fixedly installed on one side of the clamping block 30. The limiting post 31 passes through the positioning plate 29. A second spring 32 is movably sleeved on the outer circular wall of the limiting post 31. The wiring plate 25 can distribute the wires of the electrical equipment. Then, the rebound force of the two second springs 32 can make the two clamping blocks 30 clamp and fix the wires of the electrical equipment, thereby facilitating the wiring of the connecting wires of the electrical equipment. Openings are made on both sides of the interior of the enclosure 1. There are two limiting grooves 19. Two mounting caps 26 are fixedly installed on one side of the adjusting plate 20. The two mounting caps 26 are spaced apart. A first spring 27 is movably sleeved inside the mounting cap 26. A limiting block 28 is slidably connected inside the mounting cap 26. The limiting block 28 is movably sleeved with the inner circular wall of the limiting groove 19. When the worker is installing the electrical equipment, the worker can rotate the adjusting plate 20, and the limiting block 28 will move out of the limiting groove 19 and move to the position of the next limiting groove 19. Then, the rebound force of the first spring 27 will cause the limiting block 28 to re-enter the limiting groove 19, thereby limiting and fixing the adjusting plate 20. This allows for the use of the adjusting plate 20 during the installation of electrical equipment. The mounting base 16 is adjusted and fixed to prevent the adjusting plate 20 from affecting the installation of electrical equipment and the distribution of wires. Several adjusting screws 34 are fixedly installed on one side of the inner enclosure 1, and several guide rods 36 are fixedly installed on the same side. Each guide rod 36 and one adjusting screw 34 form a group. A threaded sleeve 35 is rotatably connected to one side of the mounting base 16.

The inner circular wall of the guide tube 37 is slidably connected to the guide rod 36. After the electrical equipment is installed, the operator rotates the corresponding threaded sleeve 35 according to the size of the electrical equipment. Then, under the threaded transmission action of the threaded sleeve 35, the mounting base 16 will move... The flame sensors 33 move together, allowing for individual adjustment of their positions to accommodate electrical equipment of different sizes. A fire extinguishing bag 44 is fixedly installed on one side of the upper cover 41, and several piercing nails 45 are fixedly installed on one side of the lower cover 42. When burning electrical equipment enters the upper and lower covers 41 and 42, the closing mechanism causes the piercing nails 45 to puncture the fire extinguishing bag 44 inside the upper cover 41. The fire extinguishing bag 44 then actively extinguishes the fire, preventing the electrical equipment inside the upper and lower covers 41 from continuing to burn and causing potential hazards.
[0032] Based on the above embodiments, refer to Figure 2 , Figure 3 and Figure 11 A heat sink 13 is fixedly installed on one side of the interior of the housing 1. Several cooling fans 47 are fixedly installed inside the heat sink 13 and are electrically connected to the PLC controller 8. A strong magnet 48 is fixedly installed on one side of the interior of the heat sink 13. A filter screen 49 is slidably connected inside the heat sink 13. The multiple cooling fans 47 actively dissipate heat from the interior of the housing 1, while the filter screen 49 filters out dust and impurities. The strong magnet 48 allows for quick installation and removal of the filter screen 49. A temperature and humidity sensor 11 is fixedly installed on one side of the interior of the housing 1 and is electrically connected to the PLC controller 8. Heating plates 12 are fixedly installed on both sides of the interior of the housing 1. Electrically connected to the PLC controller 8, the temperature and humidity inside the enclosure 1 can be monitored and fed back in real time via the temperature and humidity sensor 11, which can then control the use of multiple cooling fans 47. At the same time, the heating plate 12 can heat and dry the inside of the enclosure 1 when it is relatively humid. A protective cover 3 is rotatably connected to one side of the enclosure 1. A sealing groove 5 is opened on one side of the enclosure 1, and a sealing ring 6 is fixedly installed inside the sealing groove 5. A frame 7 is fixedly installed on one side of the protective cover 3. The frame 7 is movably fitted with the inner wall of the sealing groove 5. When the enclosure 1 is used in an outdoor environment, the protective cover 3 can protect the PLC controller 8 and the short-circuit grounding indicator 9. At the same time, the sealing fit between the sealing ring 6 and the frame 7 can prevent water from entering the inside of the protective cover 3 and affecting its use.
[0033] Working principle: Please refer to Figures 1-11 As shown, multiple mounting brackets 10 can be used to install electrical equipment inside the enclosure 1, and then the electrical equipment and current sensor 50 can be connected by wires. When a short circuit occurs in the electrical equipment, the current sensor 50 will feed back an electrical signal to the short circuit grounding indicator 9. At this time, the short circuit grounding indicator 9 processes the electrical signal and feeds it back to the PLC controller 8. Then the PLC controller 8 can determine the location of the short-circuited electrical equipment. Then, when the staff can open the PLC controller 8 to inspect the electrical equipment, the staff can accurately determine the location of the faulty equipment through the PLC controller 8. At this time, the PLC controller 8 controls the micro air compressor 14 to start the first pneumatic push rod 21. Then, the extension rod of the first pneumatic push rod 21 extends and drives the mounting bracket 10 and the electrical equipment to move. Then, the staff can inspect the electrical equipment alone. At the same time, because the faulty electrical equipment is moved and separated from other electrical equipment inside the enclosure 1, the staff's inspection work will not be interfered with by other electrical equipment. When the electrical equipment inside the enclosure 1 catches fire due to aging, the flame sensor 33 will detect the burning electrical equipment and then send an electrical signal back to the PLC controller 8. The PLC controller 8 then controls the start of the micro air compressor 14. At this time, the telescopic rods of the second pneumatic push rod 23 and the first pneumatic push rod 21 will move. The telescopic rod of the second pneumatic push rod 23 will retract and drive the corresponding pressure frame 22 to slide downward. Then the bottom of the pressure frame 22 will press down on the wire connection of the electrical equipment. At the same time, the telescopic rod of the first pneumatic push rod 21 will extend and move the mounting frame 10 and the burning electrical equipment out of the electrical equipment group. At this time, since the connecting wires of the electrical equipment are limited and fixed by the pressure frame 22, the wires of the electrical equipment will be separated from it during its movement, thereby cutting off the power to the electrical equipment. At this time, the electrical equipment moved by the first pneumatic push rod 21 will enter the interior of the upper cover 41 and the lower cover 42. When the electrical equipment comes into contact with the pressure sensor 46, the pressure sensor 46 will feed back an electrical signal to the PLC controller 8. Then, the PLC controller 8 controls the first electromagnet 39 corresponding to the position of the pressure sensor 46 to de-energize. At this time, the upper cover 41 attracted by the first electromagnet 39 will release its attraction and limiting effect. Then, under the elastic tension of the tension spring 43, the upper cover 41 will close to the side of the lower cover 42, and the burning electrical equipment will be wrapped inside the upper cover 41 and the lower cover 42. Then, the PLC controller 8 de-energizes the corresponding second electromagnet 40. At this time, the upper cover 41 and the lower cover 42 can be separated from the side of the mounting plate 38. This achieves the effect of facilitating real-time short-circuit monitoring of the electrical equipment inside the enclosure 1, and at the same time, facilitating the removal and protective isolation of the electrical equipment when it catches fire due to aging. This can prevent the aging electrical equipment from catching fire and causing damage to other electrical equipment inside the enclosure 1.
