Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and in particular to a dustproof and detachable power distribution cabinet for smart grids. Background Technology

[0002] With the rapid development of smart grids, distribution cabinets, as core equipment for power distribution, have expanded their application scenarios from conventional indoor environments to harsh outdoor environments, heavily polluted industrial areas, and remote extreme conditions. Currently, most mainstream distribution cabinets adopt an integrated fixed structure with a simple sealing design, suitable only for conventional indoor scenarios. They are ill-suited for complex and harsh environments, easily leading to equipment failures and safety hazards. Specific drawbacks are as follows: In outdoor dusty environments, simple sealing structures cannot effectively prevent dust from entering, easily causing poor contact and short circuits in the components inside the cabinet. The conductive sludge formed by the combination of dust and condensation can also accelerate the corrosion and aging of components. In heavy industrial plant environments, high concentrations of industrial dust and corrosive dust can easily clog the heat dissipation channels of the cabinet, while also corroding internal components, causing serious failures such as overheating and burnout, and insulation breakdown.

[0003] To address this, existing distribution cabinets typically have ventilation openings and filters installed within the cabinet to allow outside air in for heat dissipation while preventing dust and debris from entering. However, in actual use, a large amount of dust quickly accumulates on the filter surface. If not cleaned in time, this significantly reduces ventilation and heat dissipation efficiency, leading to increased internal temperature of the distribution cabinet. This can shorten the lifespan of components or even cause overheating, short circuits, and other safety hazards.

[0004] Therefore, filters need to be cleaned or replaced in a timely manner after a period of use. However, most existing filters are fixedly installed, which is not only cumbersome to disassemble and costly to maintain, but also lacks automatic dust removal function, making them unsuitable for unattended scenarios and harsh dusty environments. Summary of the Invention

[0005] The present invention provides a dustproof and detachable distribution cabinet for smart grids, in order to solve the problem mentioned in the background art that existing ordinary distribution cabinets have significant defects in dustproofing, disassembly, and maintenance, and cannot meet the needs of smart grids.

[0006] To solve the above-mentioned technical problems, the present invention provides a dustproof and detachable distribution cabinet for smart grids, including a cabinet body, a cabinet door hinged at the opening of the cabinet body, a drive frame slidably connected inside the cabinet body, connecting seats symmetrically arranged at the top and bottom positions on the side of the drive frame near the opening of the cabinet body, a movable groove opened on the outer wall of the cabinet door corresponding to the position of the connecting seat, a connecting slider slidably installed inside the movable groove, a connecting rod hinged to the outer wall of the connecting slider, and one end of the connecting rod hinged to the connecting seat; The cabinet has symmetrical installation openings on both sides. The outer wall of the drive frame is provided with a drive plate that is slidably installed at the top and bottom of the installation opening. A filter assembly is slidably connected between the drive plates inside the installation opening. The filter assembly has docking shafts symmetrically arranged at the top and bottom. The outer wall of the drive plate has a locking groove corresponding to the docking shaft. The docking shaft passes through the locking groove and is slidably connected to it.

[0007] The present invention is further configured such that a docking groove is provided inside the mounting port at the position corresponding to the docking shaft, a drive motor is provided on the outer wall of the mounting port at the position corresponding to the docking shaft, the output end of the drive motor extends into the docking groove and is fixedly installed with an output disk, and a bayonet is provided on the outer wall of the output disk at the position corresponding to the docking shaft, and the bayonet is connected to the docking groove.

[0008] The invention is further configured such that the end of the docking shaft extends into the bayonet and engages with it, the outer wall of the end of the docking shaft is a non-cylindrical design, and the inner wall of the bayonet is a non-cylindrical structure consistent with the outer wall of the end of the docking shaft.

[0009] The present invention is further configured such that a connecting groove is provided on the outer wall of the drive frame near the top and bottom positions, and a limit rod is slidably connected inside the connecting groove, and the two ends of the limit rod are connected to the inner wall of the cabinet.

[0010] The present invention is further configured such that the filter assembly includes a mounting shell slidably installed inside the mounting port, the mounting shell having mounting grooves extending through its top and bottom positions, a drive disk being rotatably installed inside the mounting grooves, the docking shaft being fixedly connected to the drive disk, and a filter screen and a movable plate being slidably installed inside the mounting shell between the drive disks, the filter screen being positioned near the opening of the mounting port.

[0011] The present invention is further configured such that a drive groove is provided on one side of the drive plate located inside the cabinet, a first connecting bolt is provided on the top of the filter screen corresponding to the position of the drive groove, and a second connecting bolt is provided on the top and bottom of the movable plate corresponding to the position of the drive groove. The ends of the first connecting bolt and the second connecting bolt extend into the drive groove and are slidably connected thereto.

[0012] The present invention is further configured such that a plurality of thin metal plates are provided on the side of the filter screen near the drive disk, a baffle is provided on the side of the thin metal plates away from the filter screen, and a plurality of baffle strips are provided on the inner wall of the mounting housing near the baffle.

[0013] The present invention is further configured such that a first ventilation hole is provided through the inner side of the mounting shell near the top and bottom of the movable plate, a second ventilation hole is provided through the side of the mounting shell near the interior of the cabinet, and a one-way valve is provided on the outer wall of the movable plate corresponding to the second ventilation hole.

[0014] The beneficial effects of the dustproof and detachable distribution cabinet for smart grids of the present invention are as follows: 1. Through the coordinated operation of components such as the drive motor, drive disc, filter screen, movable plate, metal plate, baffle, and baffle strip, dual automatic dust removal is achieved, eliminating the need for frequent manual filter screen disassembly and cleaning. The drive motor drives the output disc to rotate, and the docking shaft and bayonet precisely cooperate to transmit power. The drive disc drives the filter screen and movable plate to move relative to each other through the drive groove, forming a high-pressure airflow to back-blow the filter screen and remove floating dust. The metal plate moves with the filter screen, and the baffle and baffle strip collide to generate vibration, which is transmitted to the filter screen to shake off stubborn dust. This dual action ensures unobstructed filter screen operation, prevents the cabinet from overheating, and is suitable for unattended operation scenarios.

[0015] 2. The filter assembly is quickly assembled and disassembled through the coordinated operation of components such as the cabinet door, connecting slider, connecting rod, drive frame, and drive plate. During installation, the mating shaft engages with the locking slot, and the limiting rod guides and limits the drive frame, ensuring stable installation. For disassembly, pulling the cabinet door moves the drive frame via the connecting rod, and the drive plate pushes the filter assembly out of the mounting opening for easy removal. During installation, closing the cabinet door resets the drive frame, eliminating the need for professional personnel and significantly improving maintenance efficiency.

[0016] 3. The structure of each component is tailored to usage requirements, improving operational stability and adapting to diverse and harsh environments such as outdoor and heavy industrial settings. The non-cylindrical docking shaft and bayonet joint ensure stable power transmission, the limit rod ensures smooth component linkage, the one-way valve ensures a backflushing effect, and the baffle bar and baffle plate work together to achieve effective vibration. All components work collaboratively, providing dust prevention, automatic dust removal, and convenient assembly / disassembly functions, solving maintenance pain points and providing reliable support for smart grid power distribution.

[0023] Please see Figure 1 - Figure 7 A dustproof and detachable power distribution cabinet for smart grids includes a cabinet body 1, a cabinet door 2 hinged to the opening of the cabinet body 1, a drive frame 3 slidably connected inside the cabinet body 1, and connecting seats 31 symmetrically arranged at the top and bottom positions on the side of the drive frame 3 near the opening of the cabinet body 1. A movable groove 21 is opened on the outer wall of the cabinet door 2 corresponding to the position of the connecting seat 31. A connecting slider 22 is slidably installed inside the movable groove 21. A connecting rod 23 is hinged to the outer wall of the connecting slider 22, and one end of the connecting rod 23 is hinged to the connecting seat 31. The cabinet 1 has symmetrical installation openings 11 on both sides. The outer wall of the drive frame 3 is provided with drive plates 33 that are slidably installed on the top and bottom of the inner side of the installation openings 11. The filter assembly 5 is slidably connected between the drive plates 33 inside the installation openings 11. The filter assembly 5 has docking shafts 532 symmetrically arranged on the top and bottom of the top and bottom. The outer wall of the drive plate 33 has a locking groove 34 corresponding to the position of the docking shaft 532. The docking shaft 532 passes through the locking groove 34 and is slidably connected to it.

[0024] By adopting the above technical solution, dual automatic dust removal is achieved through the linkage of components such as drive motor 4 and drive disk 53. The docking shaft 532 and bayonet 42 adopt a non-cylindrical transmission interface to ensure stable transmission and enable automatic alignment of filter assembly 5 during installation, eliminating the need for frequent manual disassembly and cleaning of filter screen 52. The filter assembly 5 is conveniently disassembled and assembled through the linkage of components such as cabinet door 2 and connecting slider 22. Cabinet door 2 and drive frame 3 form a linkage mechanism through connecting slider 22 and connecting rod 23 in movable groove 21, ensuring that the opening and closing angle of cabinet door 2 is linearly related to the displacement of drive frame 3. Drive plate 33 forms a wedge mechanism with docking shaft 532 through locking groove 34, which can press filter assembly 5 or unlock it. The double locking groove 34 design ensures symmetrical force. The docking shaft 532 and mounting port 11, and the limit rod 13 and connecting groove 32 guide and limit the fit to prevent shaking and displacement, greatly improving maintenance efficiency.

[0025] A docking groove 12 is provided inside the mounting port 11 at the position corresponding to the docking shaft 532. A drive motor 4 is provided on the outer wall of the mounting port 11 at the position corresponding to the docking shaft 532. The output end of the drive motor 4 extends into the docking groove 12 and is fixedly mounted with an output plate 41. A bayonet 42 is provided on the outer wall of the output plate 41 at the position corresponding to the docking shaft 532, and the bayonet 42 is connected to the docking groove 12. The end of the docking shaft 532 extends into the bayonet 42 and engages with it. The outer wall of the end of the docking shaft 532 is a non-cylindrical design, and the inner wall of the bayonet 42 is a non-cylindrical structure consistent with the outer wall of the end of the docking shaft 532. A connecting groove 32 is provided on the outer wall of the drive frame 3 near the top and bottom. A limit rod 13 is slidably connected inside the connecting groove 32, and the two ends of the limit rod 13 are connected to the inner wall of the cabinet 1.

[0026] By adopting the above technical solution, the output disc 41 of the drive motor 4 forms a non-cylindrical meshing structure with the docking shaft 532 of the filter assembly 5 through the bayonet 42, ensuring the transmission torque. Furthermore, the filter assembly 5 can automatically align during installation without manual precision alignment. The docking shaft 532 can slide axially within the docking groove 12, meeting the movement requirements of the filter assembly 5. The limiting rod 13 passes through the connecting groove 32 of the drive frame 3, forming a bidirectional sliding pair. The limiting rod 13 provides a guiding constraint to the drive frame 3, strictly limiting the movement trajectory of the drive frame 3. The locking groove 34 of the drive plate 33 and the docking shaft 532 of the filter assembly 5 form a wedge mechanism. When the cabinet door 2 is closed, the inclined surface of the locking groove 34 presses against the docking shaft 532, firmly locking the filter assembly 5 within the mounting opening 11. When the cabinet door 2 is opened, the locking groove 34 pushes the docking shaft 532 in the opposite direction, causing the filter assembly 5 to move outward for easy disassembly. The simultaneous operation of the two drive plates 33 ensures that the docking shaft 532 is subjected to balanced force, preventing the filter assembly 5 from tilting or jamming.

[0027] The filter assembly 5 includes a mounting shell 51 that is slidably installed inside the mounting port 11. Mounting grooves 512 are formed through the top and bottom of the mounting shell 51. A drive disc 53 is rotatably mounted inside the mounting grooves 512. A docking shaft 532 is fixedly connected to the drive disc 53. A filter screen 52 and a movable plate 54 are slidably installed inside the mounting shell 51 between the drive discs 53. The filter screen 52 is positioned near the opening of the mounting port 11. A drive groove 531 is formed on one side of the drive disc 53 inside the cabinet 1. A first docking bolt 523 is provided on the top of the filter screen 52 corresponding to the position of the drive groove 531. A second docking bolt 542 is provided on the top and bottom of the movable plate 54 corresponding to the positions of the drive groove 531. The ends of both the first and second docking bolts 523 and 542 extend into the drive groove 531 and are slidably connected thereto. A first vent 513 is provided through the inner side of the mounting shell 51 near the top and bottom of the movable plate 54. A second vent 514 is provided through the side of the mounting shell 51 near the interior of the cabinet 1. A one-way valve 541 is provided on the outer wall of the movable plate 54 corresponding to the second vent 514. Several thin metal plates 521 are provided on the side of the filter screen 52 near the drive plate 53. A baffle 522 is provided on the side of the thin metal plates 521 away from the filter screen 52. Several baffle strips 511 are provided on the inner wall of the mounting shell 51 near the baffle 522.

[0028] By adopting the above technical solution, when the drive disc 53 rotates, the first connecting bolt 523 can slide along the drive groove 531, driving the filter screen 52 to perform reciprocating linear motion; the second connecting bolt 542 slides in the opposite direction along the same drive groove 531, causing the movable plate 54 and the filter screen 52 to generate relative displacement; the drive disc 53 can complete a complete dust cleaning cycle with one rotation, realizing the automated linkage of the dust cleaning action. When the movable plate 54 moves, the one-way valve 541 can close the second vent 514, forcing air to form a high-pressure airflow through the first vent 513. When the movable plate 54 moves in the opposite direction, the one-way valve 541 opens, and external air can be quickly replenished into the mounting shell 51 through the second vent 514, ensuring that there is always enough air supply, so that there is always a high-pressure airflow impacting the back of the filter screen 52, improving the back-blowing dust cleaning effect. When the baffle 522 collides with the baffle strip 511, it can generate high-frequency vibration, which is used to shake off stubborn dust on the filter screen 52.

[0029] Working principle and usage process of this invention: When the distribution cabinet is working normally, the cabinet door 2 is closed, and the filter assembly 5 is fully embedded inside the mounting port 11, achieving a sealed dustproof environment for the cabinet 1 while ensuring ventilation and heat dissipation. The air extraction device installed inside the cabinet 1 works continuously to extract the hot air generated by the operation of the components inside the cabinet. External air is filtered by the filter assembly 5 and then enters the cabinet 1 through the vent 513, forming a complete ventilation and heat dissipation cycle.

[0030] Among them, the mounting shell 51 of the filter component 5 plays a fixed support role, and the filter screen 52 is set at the position near the opening of the mounting port 11, which can effectively block external wind sand, industrial dust and other debris from entering the cabinet 1, avoiding dust from causing poor contact, short circuit or corrosion and aging of components inside the cabinet. This is also the basic guarantee for the core dustproof effect of the power distribution cabinet.

[0031] After prolonged use, a large amount of dust will accumulate on the surface of the filter element 52. If not cleaned in time, this will block the ventilation channel, reduce heat dissipation efficiency, and consequently cause the internal temperature of the cabinet 1 to rise, shorten the service life of components, or even cause safety accidents. Therefore, the filter element 5 will automatically clean itself after a period of use. First, the drive motor 4 will be started. The output end of the drive motor 4 will drive the output disk 41 to rotate. The bayonet 42 on the output disk 41 will engage with the docking shaft 532. The end of the docking shaft 532 is a non-cylindrical design, which matches the inner wall structure of the bayonet 42. This ensures that the rotational power of the output disk 41 is stably transmitted to the docking shaft 532, avoiding slippage during power transmission and ensuring the stability of the dust removal action. The docking shaft 532 drives the drive disk 53 to rotate synchronously. The drive groove 531 on the drive disk 53 is slidably connected to the first docking bolt 523 of the filter screen 52 and the second docking bolt 542 of the movable plate 54. The rotation of the drive disk 53 will pull the first docking bolt 523 and the second docking bolt 542 through the drive groove 531, thereby controlling the filter screen 52 and the movable plate 54 to move rapidly relative to each other at the same time. During the movement of the movable plate 54, it will first block the vent 513 on the mounting shell 51. Combined with the one-way conduction characteristic of the one-way valve 541, it can effectively prevent air leakage between the filter screen 52 and the movable plate 54. At this time, the relative movement of the two will compress the air in the middle, generating a high-pressure airflow. The high-pressure airflow blows in the opposite direction towards the filter screen 52, which can quickly blow away the floating dust accumulated on the surface of the filter screen 52, achieve preliminary dust removal, and ensure the filtration and ventilation efficiency of the filter screen 52.

[0032] However, some dust that is difficult to remove may still remain. Therefore, for stubborn dust on the surface and in the pores of the filter screen 52, high-pressure backflushing alone is insufficient to completely remove it. This is where the metal plate 521 inside the filter screen 52 comes into play. The metal plate 521 is rigidly connected to the filter screen 52 and can move back and forth rapidly in sync with the filter screen 52. As a vibration transmission carrier, it can efficiently transmit vibration to the entire filter screen 52, preventing vibration dispersion and ensuring that all areas of the filter screen 52 receive uniform vibration.

[0033] The baffle 522 on the metal sheet 521 has good bending deformation ability and elastic rebound performance. In its initial state, it is naturally straight. The baffle 511 on the inner wall of the mounting shell 51 is a rigid structure, positioned corresponding to the baffle 522, and slightly higher than the initial height of the baffle 522. It serves as a fixed blocking element to support the bending and rebound of the baffle 522. When the baffle 522 moves towards the baffle 511 along with the metal sheet 521, it will contact the baffle 511 and be blocked. The continuous movement of the filter screen 52 and the metal sheet 521 will generate a pushing force on the baffle 522, causing the baffle 522 to undergo elastic bending deformation and accumulate elastic potential energy until the free end of the baffle 522 passes the baffle 511.

[0034] After the baffle plate 522 passes the baffle strip 511, the obstruction force disappears instantly, and the accumulated elastic potential energy is released rapidly. The baffle plate 522 quickly rebounds to its initial state. During the rebound, it undergoes a momentary elastic collision with the other baffle strips 511, generating a short and powerful instantaneous vibration. This vibration is rapidly transmitted to the filter screen 52 through the metal plate 521, causing the filter screen 52 to generate high-frequency micro-vibration as a whole. This disrupts the adhesion between the stubborn dust and the surface of the filter screen 52, causing the stubborn dust in the pores to loosen and fall off.

[0035] The detached stubborn dust is immediately blown off the surface of the filter screen 52 by the synchronous high-pressure back-blowing airflow, achieving a dual dust removal effect of "back-blowing to remove floating dust and vibration to shake off stubborn dust". The drive disk 53 rotates continuously, which drives the filter screen 52, metal plate 521 and baffle 522 to move back and forth continuously. The baffle 522 continuously interacts with the baffle bar 511 in a "contact-bending-passing-rebounding" cycle, continuously generating vibration and cooperating with the back-blowing airflow to ensure that the filter screen 52 is thoroughly cleaned, avoiding clogging of the filter screen 52, and ensuring the long-term heat dissipation and dust prevention performance of the power distribution cabinet. There is no need for frequent manual disassembly and cleaning of the filter screen 52, reducing maintenance costs and making it suitable for unattended operation scenarios.

[0036] When the filter assembly 5 is installed normally, the top end of the docking shaft 532 is engaged in the bayonet 42 of the output disc 41, and the lower end is embedded in the locking groove 34 of the drive plate 33. The locking groove 34 fixes the docking shaft 532, ensuring that the filter assembly 5 is stably installed inside the installation port 11, preventing loosening or displacement during operation, and ensuring the stability of dust prevention and ventilation. At the same time, the drive frame 3 is slidably connected to the limiting rod 13 through the connecting groove 32. The two ends of the limiting rod 13 are connected to the inner wall of the cabinet 1, which can limit and guide the movement of the drive frame 3, ensuring that the drive frame 3 moves smoothly and avoids deviation.

[0037] During disassembly, simply pull the cabinet door 2 outwards. With the cabinet door 2 closed, the connecting slider 22 is located at one end of the movable groove 21. As the cabinet door 2 is opened, the connecting slider 22 slides along the movable groove 21, simultaneously pulling the connecting rod 23. One end of the connecting rod 23 is hinged to the connecting slider 22, and the other end is hinged to the connecting seat 31 of the drive frame 3. As the cabinet door 2 gradually opens, the connecting rod 23 pulls the connecting seat 31, thereby causing the entire drive frame 3 to move towards the cabinet door 2.

[0038] When the drive frame 3 moves, it will drive the drive plates 33 on both sides to move synchronously. The locking groove 34 on the drive plate 33 will squeeze the docking shaft 532, pushing the filter assembly 5 out of the mounting port 11 until the docking shaft 532 moves to the other end of the locking groove 34. At this time, part of the filter assembly 5 extends out of the mounting port 11. The staff only needs to gently pull the filter assembly 5 to remove it from the mounting port 11 and complete the disassembly, which greatly simplifies the disassembly operation and reduces the difficulty and time of maintenance.

[0039] After inspection or replacement, the filter assembly 5 is reinserted into the mounting port 11, ensuring that the docking shaft 532 aligns with the locking groove 34 and the bayonet 42. Then, the cabinet door 2 is closed. During the closing process, the cabinet door 2 pushes the connecting seat 31 through the connecting slider 22 and the connecting rod 23, causing the drive frame 3 to reset. The drive plate 33 moves synchronously, and the locking groove 34 presses the docking shaft 532 again, pulling the filter assembly 5 back into the mounting port 11 and fixing it securely, thus completing the installation. The entire disassembly and assembly process does not require professional personnel and is suitable for rapid maintenance needs under complex working conditions.

[0040] The three main functions of the power distribution cabinet—normal operation, automatic dust removal, and convenient assembly / disassembly—are achieved through precise linkage of various components: the opening and closing of the cabinet door 2 drives the frame 3 to move, thereby controlling the assembly / disassembly of the filter assembly 5; the drive motor 4 drives the drive disc 53 to rotate, realizing the relative movement of the filter screen 52 and the movable plate 54 (back-blowing dust removal) and the vibration of the metal plate 521 and the baffle 522 (stubborn dust removal); the structural design of each component (such as the non-cylindrical docking shaft 532, the limit rod 13, the one-way valve 541, etc.) further improves the stability and reliability of the equipment operation.

[0041] Its core beneficial effects are integrated into each process step. It achieves efficient dust prevention through filter 52 and sealing structure, avoiding component failure caused by dust. It also adapts to unattended scenarios and reduces maintenance costs through dual automatic dust removal function. Furthermore, it simplifies operation and improves maintenance efficiency through the linkage disassembly and assembly design of cabinet door 2. Overall, it is adapted to the complex and harsh application scenarios of smart grids and ensures the stable operation of power distribution equipment.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
