Description

Technical Field

[0001] This invention relates to the field of ring network box technology, and in particular to a compact prefabricated metal enclosed ring network box. Background Technology

[0002] A metal-enclosed ring main unit is a power distribution device that integrates switch cabinets, power supply cabinets, automation terminals, communication control equipment, etc., into a movable, sealed, and moisture-proof metal enclosure. It is used for receiving and distributing electrical energy, and at the same time plays a role in controlling, protecting, and detecting circuits.

[0003] Currently, traditional metal-enclosed ring main units mostly adopt a fixed structure, with heat dissipation vents constantly open and exposed to the outdoor environment. This makes them susceptible to external factors such as dust, rain, and small animals, leading to dust accumulation and moisture buildup inside the equipment, which in turn affects operational stability and lifespan. To resolve the conflict between heat dissipation and protection, some ring main units use external dust covers or rely on regular manual cleaning. However, these methods still suffer from structural redundancy, high cleaning intensity, high maintenance costs, and low automation.

[0004] In summary, existing technologies suffer from problems such as difficulty in balancing heat dissipation and protection, inconvenience in disassembly and repair, and high maintenance costs. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of traditional ring main units, such as difficulty in balancing heat dissipation and protection, inconvenience in disassembly and repair, and high maintenance costs, and to propose a compact prefabricated metal enclosed ring main unit.

[0006] To achieve the above objectives, the present invention employs the following technology: a compact prefabricated metal enclosed ring network box, including an outer protective cover; The ring mesh box is installed inside the outer protective cover; An electric lifting cylinder is fixedly installed on the top surface of the outer protective cover. The piston rod of the electric lifting cylinder is connected to the top surface of the ring network box and is used to drive the ring network box to extend or retract into the outer protective cover. It also includes: a heat dissipation device; the heat dissipation device includes a curved heat dissipation pipe fixed inside the outer protective cover and movably embedded in the bottom surface of the outer protective cover, a heat dissipation fan fixed inside the heat dissipation port on the back of the ring mesh box, and a dustproof net fixed inside the bottom end port of the curved heat dissipation pipe. The mounting and engaging structure includes an engaging track fixed to the back of the ring network box and located at the heat dissipation port, and a rubber frame fixedly sleeved on the port of the curved heat dissipation pipe. The rubber frame and the engaging track are engaged and inserted into each other. When the electric lifting cylinder drives the ring network box to extend or retract into the outer protective cover, the rubber clip frame and the locking track are simultaneously inserted or separated, so that the curved heat dissipation pipe is connected or disconnected from the heat dissipation port.

[0007] As a compact prefabricated metal enclosed ring network box of the above-mentioned technology, a pair of mounting grooves are fixedly connected to the outer side of the outer protective cover. A protective side plate with an inner wall that fits against the side of the outer protective cover is slidably connected to the mounting groove. A protective bottom plate is fixedly connected to the bottom of the ring network box. The protective bottom plate is fitted into the notch on the bottom of the outer protective cover. A reinforcing layer is provided inside the outer protective cover, the protective bottom plate, and the protective side plate. A metal reinforcing plate is fixedly installed inside the reinforcing layer.

[0008] As a compact prefabricated metal enclosed ring network box of the above technology, it also includes a self-cleaning component, which includes a swing scraper, a cleaning component, an auxiliary seat, and a pressing component; The auxiliary seat is fixed to the bottom surface of the outer protective cover. The swing scraper is rotatably mounted on the auxiliary seat. A return spring is fixedly installed inside the cleaning component. The cleaning component is sleeved on the swing scraper. The return spring inside the cleaning component is connected to the end of the swing scraper. The swing scraper is divided into a pressing section and a curved scraping section. A downward pressing groove is opened on the inner wall surface of the pressing section. The pressing component includes an inclined telescopic rod and a pressure column fixedly connected to the end of the telescopic rod. The end of the telescopic rod is rotatably mounted on the side of the protective base plate. The pressure column is slidably connected to the downward pressing groove. When the ring net box extends or retracts, the pressure column slides back and forth in the downward pressing groove and drives the cleaning component to clean the dust net.

[0009] As a compact prefabricated metal enclosed ring main unit of the above-mentioned technology, the ring main unit is provided with a frame plate, which divides the interior of the ring main unit into an equipment area and a heat dissipation area. Several frames for installing equipment components are fixedly embedded in the equipment area on the frame plate. Each frame is provided with an inner frame, and each inner frame has a pad rod on its inner wall. Screws for fixing equipment components are provided on the pad rod.

[0010] As a compact prefabricated metal enclosed ring network box of the above technology, a pair of mounting plates are fixedly connected to the frame plate below the frame body. A mounting seat is rotatably arranged in the mounting plate. A temporary storage collection box is arranged in the mounting seat. Sliding grooves are opened on both sides of the inner wall of the mounting seat. Guide blocks that slide with the sliding grooves are fixedly connected to both sides of the temporary storage collection box. Several partitions are fixedly arranged in the port of the temporary storage collection box, and the partitions divide the temporary storage collection box into several storage compartments.

[0011] As a compact pre-assembled metal enclosed ring network box of the above technology, a first magnetic block is fixedly connected to one side end of each of the slides, and a second magnetic block is fixedly connected to the side of each of the guide blocks; when the guide block slides to the end of the slide, the first magnetic block and the second magnetic block attract each other.

[0012] As a compact prefabricated metal enclosed ring network box of the above technology, the heat dissipation device further includes a heat conduction channel disposed in the heat dissipation area. The heat conduction channel includes a main channel and several secondary channels. The main channel is connected to the heat dissipation port, and the several secondary channels correspond to the ports of the frame of each layer.

[0013] As a compact pre-installed metal enclosed ring network box of the above technology, the inner walls on both sides of the outer protective cover are provided with limiting grooves, and the outer sides of the ring network box are slidably set in the limiting grooves by limiting blocks.

[0014] In summary, due to the adoption of the above-mentioned technology in the compact prefabricated metal enclosed ring network box, the beneficial effects of this invention are: (1) This invention, by setting up an electric lifting cylinder, installing a locking structure and a curved heat dissipation pipe, allows the rubber frame to automatically separate from the locking track when the ring network box is extended for operation, exposing the structure inside the heat dissipation port. This allows operators to disassemble and maintain the heat dissipation fan without having to operate in the confined environment inside the box, making operation very convenient and greatly reducing the labor intensity of subsequent cleaning and maintenance personnel. When the ring network box is retracted into the protective state, the rubber frame and locking track are inserted, allowing the curved heat dissipation pipe to automatically connect with the heat dissipation port, achieving efficient heat dissipation in conjunction with the heat dissipation fan. The sealed heat dissipation port effectively prevents external dust and moisture from entering, achieving coordinated control of heat dissipation and protection. In the protective state, the heat dissipation port is sealed and connected to the heat dissipation through the curved heat dissipation pipe, effectively preventing external dust and moisture from entering, thus significantly improving the adaptability of the ring network box in harsh outdoor environments. At the same time, in the non-working state, dust is less likely to accumulate at the heat dissipation fan and heat dissipation port, avoiding the heat dissipation failure problem caused by dust accumulation and moisture in traditional fixed heat dissipation structures, and significantly improving the long-term operational reliability of the heat dissipation system.

[0015] (2) By setting up a self-cleaning component, the present invention utilizes the mechanical linkage during the lifting process of the ring net box to drive the swinging scraper to drive the cleaning component to swing back and forth, thereby automatically cleaning the dust net, avoiding the problem of dust accumulation and blockage after long-term use of the dust net, reducing the frequency of manual maintenance, and improving the long-term stability of the heat dissipation system.

[0016] (3) By setting up heat conduction channels, including main channels and multiple secondary channels, the cold air introduced by the heat dissipation fan is evenly guided to the equipment installation frame of each layer, thereby achieving layered directional heat dissipation. This design effectively avoids the problem of uneven temperature distribution inside the traditional ring network box, prevents some components from running at high temperature for a long time and thus accelerating aging or failure, thereby reducing thermal stress and thermal aging effects, and improving the operational reliability and service life of equipment components.

[0017] (4) By setting up a temporary storage collection box and mounting base structure, the present invention facilitates the temporary storage of small parts such as screws and washers during equipment installation or maintenance. Combined with the magnetic positioning structure, it ensures that the collection box is stably stored when not in use, thus improving the convenience of on-site operations.

[0020] The following will describe, with reference to the accompanying drawings of the embodiments of the present invention, a compact prefabricated metal enclosed ring network box according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0021] like Figures 1-9 As shown, a compact prefabricated metal enclosed ring mesh box includes an outer protective cover 1, the bottom surface of which has a notch 101. The ring mesh box 2 is installed inside the outer protective cover 1. It should be noted that the inner walls on both sides of the outer protective cover 1 are provided with limiting grooves 103. The outer sides of the ring mesh box 2 are slidably installed in the limiting grooves 103 by limiting blocks 104, so as to limit and guide the ring mesh box 2 and ensure that its extension and retraction actions are more stable during the driving lifting process. The electric lifting cylinder 14 is fixedly installed on the top surface of the outer protective cover 1. The piston rod of the electric lifting cylinder 14 is connected to the top surface of the ring mesh box 2 and is used to drive the ring mesh box 2 to lift relative to the outer protective cover 1, so as to realize the extension or retraction operation. It also includes: a heat dissipation device 3, used to dissipate heat and cool down the ring network box 2 during operation; The heat dissipation device 3 includes a curved heat dissipation pipe 31 fixed inside the outer protective cover 1 and whose bottom surface is movably embedded in the bottom surface of the outer protective cover 1, a heat dissipation fan 32 fixed inside the heat dissipation port 21 on the back of the ring mesh box 2, and a dustproof net 33 fixed inside the bottom end port of the curved heat dissipation pipe 31. And the mounting locking structure 34, which includes a locking rail 341 fixed to the back of the ring mesh box 2 and located at the heat dissipation port 21 and a rubber frame 342 fixedly sleeved on the port of the curved heat dissipation pipe 31. The rubber frame 342 and the locking rail 341 are engaged and plugged in. When the electric lifting cylinder 14 drives the ring network box 2 to extend or retract into the outer protective cover 1, the rubber clip frame 342 and the locking track 341 simultaneously complete the insertion or separation action, thereby connecting or disconnecting the curved heat dissipation pipe 31 from the heat dissipation port 21; at this time, the heat dissipation fan 32 can be started to dissipate heat from the ring network box 2. Specifically, the heat dissipation device 3 also includes a heat conduction channel 35 disposed within the heat dissipation area 52. The heat conduction channel 35 includes a main channel 351 and several secondary channels 352. The main channel 351 is connected to the heat dissipation port 21, and the several secondary channels 352 correspond to the ports of each layer of the frame 53. When the ring main unit 2 is put into operation, the cooling fan 32 is started. External air enters the heat dissipation port 21 through the dustproof net 33 and the bent heat dissipation pipe 31, and then flows through the main channel 351 of the heat conduction channel 35 to the secondary channels 352, realizing layered and directional heat dissipation of electrical components in each layer of the frame 53 within the equipment area 51. The hot air is finally discharged by the cooling fan 32. This design effectively avoids the problem of uneven temperature distribution inside the traditional ring main unit 2, and improves the operational reliability and service life of the equipment components.

[0022] As a preferred embodiment, a frame plate 5 is provided inside the ring network box 2. The frame plate 5 divides the interior of the ring network box 2 into an equipment area 51 and a heat dissipation area 52. Several frames 53 for installing equipment components are fixedly embedded in the equipment area 51 on the frame plate 5, which can realize the partitioned arrangement. More specifically, each frame 53 contains an inner frame 531, and the inner wall of each inner frame 531 is provided with a pad rod 532. The pad rod 532 is equipped with screws for fixing equipment components. During use, the inner frame 531 can be selected and installed according to the equipment components, making it more versatile. After the equipment components are installed on the pad rod 532, a gap is left between their bottom and the inner frame 531 to facilitate heat dissipation and prevent damage to the bottom due to insufficient heat dissipation.

[0023] As a further preferred embodiment, a pair of mounting plates 54 are fixedly connected to the shelf 5 below the frame 53. A mounting base 541 is rotatably installed inside the mounting plate 54. A temporary storage collection box 542 is installed inside the mounting base 541. Sliding grooves 543 are opened on both sides of the inner wall of the mounting base 541. Guide blocks 544 that slide with the sliding grooves 543 are fixedly connected to both sides of the temporary storage collection box 542. Several partitions are fixedly installed inside the port of the temporary storage collection box 542. The partitions divide the temporary storage collection box 542 into several storage compartments 545 for placing various small parts. More specifically, a first magnetic block 546 is fixedly connected to one side of each slide 543, and a second magnetic block 547 is fixedly connected to the side of each guide block 544; when the guide block 544 slides to the end of the slide 543, the first magnetic block 546 and the second magnetic block 547 attract each other, thereby fixing the temporary storage collection box 542.

[0024] like Figures 1-9 As shown, in order to solve the problem of difficulty in balancing heat dissipation and protection in traditional ring network boxes, a pair of mounting slots 13 are fixedly connected to the outer side of the outer protective cover 1. A protective side plate 12 with its inner wall in contact with the side of the outer protective cover 1 is slidably connected to the mounting slots 13. A protective bottom plate 11 is fixedly connected to the bottom of the ring network box 2. The protective bottom plate 11 is fitted into the notch 101 on the bottom of the outer protective cover 1. The outer protective cover 1, the protective bottom plate 11 and the protective side plate 12 form a fully enclosed protection for the ring network box 2, thereby effectively preventing damage. More specifically, the outer protective cover 1, the protective base plate 11, and the protective side plate 12 are all equipped with a reinforcing layer, and a metal reinforcing plate 102 is fixedly installed in the reinforcing layer, which can further improve the overall structural strength.

[0025] like Figures 1-9 As shown in this embodiment, in order to solve the problem that traditional ring network boxes require manual subsequent cleaning, which increases the cleaning intensity, a self-cleaning component 4 is designed. The self-cleaning component 4 includes a swing scraper 41, a cleaning component 42, an auxiliary seat 44, and a pressing component 43. It should be noted that the cleaning component 42 is selected as a cleaning soft brush. The auxiliary seat 44 is fixed to the bottom surface of the outer protective cover 1. The swing scraper 41 is rotatably mounted on the auxiliary seat 44. A return spring 45 is fixedly mounted inside the cleaning component 42. The cleaning component 42 is sleeved on the swing scraper 41. The return spring 45 inside the cleaning component 42 is connected to the end of the swing scraper 41. The swing scraper 41 is divided into a pressing section 401 and a curved scraping section 402. The inner wall of the pressing section 401 is provided with a downward pressing groove 403. The pressing component 43 includes an inclined telescopic rod 431 and a pressing column 432 fixedly connected to the end of the telescopic rod 431. The end of the telescopic rod 431 is rotatably mounted on the side of the protective base plate 11. The pressing column 432 is slidably connected to the downward pressing groove 403. When the ring box 2 extends or retracts, the pressing column 432 slides back and forth in the downward pressing groove 403 and drives the cleaning component 42 to clean the dust net 33. This design enables the dustproof net 33 to be automatically cleaned during the lifting and lowering of the equipment, reducing the workload of manual maintenance.

[0026] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: Combination Figures 1-9The principle of the compact prefabricated metal enclosed ring network box provided by the present invention is as follows: In the non-working or transport state, the ring mesh box 2 is retracted into the outer protective cover 1, and the protective bottom plate 11 and the protective side plate 12 are closed. The outer protective cover 1, the protective bottom plate 11, and the protective side plate 12 form a fully enclosed protection for the ring mesh box 2, thereby effectively preventing damage. At this time, the electric lifting cylinder 14 is in the retracted state, and the locking rail 341 fixed to the back of the ring mesh box 2 and the rubber clip frame 342 on the port of the curved heat dissipation pipe 31 are gradually inserted to achieve a sealed connection between the heat dissipation port 21 and the curved heat dissipation pipe 31.

[0027] After the ring network box 2 is in place, when the ring network box 2 is installed on site and put into operation, the cooling fan 32 is started. External air enters the heat dissipation port 21 through the dustproof net 33 and the bent heat dissipation pipe 31, and is diverted through the main flow channel 351 and the secondary flow channel 352 of the heat conduction channel 35 to force heat dissipation and cooling of the electrical components in each layer of the frame 53 in the equipment area 51. The hot air is discharged by the cooling fan 32.

[0028] When the equipment stops working or requires maintenance, the piston rod of the electric lifting cylinder 14 drives the ring mesh box 2 to extend from the notch 101 at the bottom of the outer protective cover 1. At this time, the locking track 341 separates from the rubber clamp frame 342, and the heat dissipation channel is automatically cut off. As the protective base plate 11 at the bottom of the ring mesh box 2 continues to descend, the pressure piece 43 on the side of the protective base plate 11 slides in the downward pressure groove 403 until it drives the cleaning piece 42 on the swing scraper 41 to clean the dust on the dustproof net 33 inside the port of the curved heat dissipation pipe 31. During this process, the telescopic rod 431 of the pressure piece 43 is used to adaptively lengthen or shorten, and the cleaning piece 42 compresses the internal return spring 45 to adaptively extend and retract. After the ring mesh box 2 is fully extended from the outer protective cover 1, the structure inside the heat dissipation port 21 is exposed, and the operator can disassemble and maintain the heat dissipation fan 32 without having to operate in the confined environment inside the box. The operation is very convenient and greatly reduces the labor intensity of subsequent cleaning and maintenance personnel.

[0029] After maintenance is completed, the piston rod of the electric lifting cylinder 14 retracts, the protective base plate 11 rises with the ring mesh box 2, the pressure component 43 drives the swing scraper 41 to rotate, and the cleaning component 42 scrapes and cleans the dustproof net 33, completing the secondary cleaning of the dustproof net 33 and ensuring ventilation efficiency for the next use. The entire process of heat dissipation and cleaning is achieved through the linkage of the lifting action, requiring no additional operation, and features a compact structure and a high degree of automation.

[0030] When repairing the equipment components inside the ring main unit 2, the door of the ring main unit 2 can be opened directly, or the door can be opened after the ring main unit 2 extends out from the outer protective cover 1. After opening the door, the mounting base 541 and the temporary storage collection box 542 are flipped down, and the temporary storage collection box 542 is pulled out. When the guide block 544 slides to the end of the slide groove 543, the first magnetic block 546 and the second magnetic block 547 attract each other. Several storage compartments 545 inside the temporary storage collection box 542 are used to place various small parts, and the space between the temporary storage collection box 542 and the shelf 5 can be used to temporarily place test equipment and its accessories. After use, it can be flipped up again. This design has a higher space utilization rate and is suitable for outdoor compact power distribution scenarios.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technology of the present invention, to a compact prefabricated metal enclosed ring network box and its inventive concept, should be covered within the scope of protection of the present invention.
