Description

Technical Field

[0002] Distribution cabinets are indispensable key equipment in power distribution systems, and their operational stability directly affects the reliability of power supply and the safety of electrical equipment. In industrial power supply and building power distribution environments, distribution cabinets need to withstand multiple tests such as current load fluctuations, mechanical vibrations, and temperature and humidity changes over a long period of time. Therefore, their internal structure is required to have reliable installation stability and continuous protection capabilities.

[0003] Traditional power distribution cabinets generally suffer from limitations such as limited structural functionality and insufficient adaptability. Internal components are often secured with bolts, limiting installation and adjustment space and posing a risk of loosening under continuous vibration. Cooling systems typically rely on natural convection or a single fan, making intelligent adjustment based on internal temperature changes difficult and potentially leading to localized overheating.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] 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. Example 1

[0026] As attached Figures 1 to 9 The diagram shows a power distribution cabinet device. The cabinet body 1 is formed by bending a metal plate, and the mounting structure 3 is installed inside the cabinet body 1. The bottom of the cabinet body 1 is equipped with a raised base, and the internal space is divided into an equipment installation area and a cable routing area. The power distribution component 2 is slidably connected to the guide rail 303. The mounting bracket 301 is fixed to the inner wall of the cabinet body 1 by angle brackets, and the guide rail 303 is a grooved track arranged parallel to the load-bearing beam of the mounting bracket 301.

[0027] The locking mechanism 302 also includes a drive component 309 and a connecting seat 310. The locking rod 304 of the locking mechanism 302 is configured as a stepped shaft structure, and the locking head 305 adopts a wedge-shaped block and is hinged to the front end of the locking rod 304 by a pin. When the drive component 309 pushes the locking rod 304, the wedge-shaped surface of the locking head 305 contacts the slot of the power distribution component 2 and gradually presses it. The connecting seat 310 is provided with a copper-based bushing, and the locking rod 304 passes through the bushing and can slide axially. The locking rod 304 is provided with a first mating surface 306, a second mating surface 307, and a locking part 308.

[0028] The auxiliary support 311 is made of nylon and has a cushioning pad. The cable manager 312 is a combination of cable management ring and cable tie seat. The identification plate 313 is fixed to the crossbeam of the mounting bracket 301 through a slot.

[0029] The fixed seat 403 of the anti-loosening mechanism 4 is welded to the side beam of the mounting frame 301, and the guide post 404 is set on the fixed seat 403. The guide post 404 is a chrome-plated optical shaft and is vertically fixed to the fixed seat 403. The anti-loosening block 401 is provided with a guide hole that fits with the guide post 404 with clearance. The elastic element 402 is a helical spring and is pre-pressed between the anti-loosening block 401 and the fixed seat 403. The first guide surface 405 is a concave arc surface, the second guide surface 406 is a convex arc surface, and the positioning groove 407 adopts a semi-circular groove structure. When the locking rod 304 moves, its rod body slides into the positioning groove 407 along the first guide surface 405, and the anti-loosening block 401 always maintains contact pressure with the locking rod 304 under the action of the elastic element 402. The operating part 408 is provided with anti-slip texture. The first limiting element 409 and the second limiting element 410 are screwed into the mounting frame 301 with limiting screws to form a mechanical limit on the movement range of the operating part 408.

[0030] The centrifugal fan 501 of the heat dissipation system 5 is fixed to the top plate of the cabinet 1 by shock-absorbing pads. The temperature detector 502 uses a PT100 sensor and is evenly distributed in various heat-generating areas inside the cabinet 1. The control unit 503 is equipped with a temperature threshold comparison circuit. When the temperature detector 502 detects a value exceeding the set range, the control unit 503 starts the centrifugal fan 501 and adjusts its speed. The ventilation grille 504 adopts a double-layer louver structure, the filter structure 505 uses a washable polyester filter, and the air guide shroud 506 adopts a volute structure to directionally discharge hot air. When the centrifugal fan 501 is working, an airflow path is formed inside the cabinet 1, with air entering from the bottom and exiting from the top. External air enters the cabinet 1 after being filtered by the ventilation grille 504, and hot air is efficiently discharged under the guidance of the air guide shroud 506.

[0031] The access control sensor 601 of the protection system 6 is a Hall sensor embedded in the door frame of the cabinet 1. The status indicator light 602 uses RGB tri-color LED beads integrated into the panel, and the alarm 603 is an explosion-proof audible and visual alarm. When the cabinet door is opened, the access control sensor 601 triggers a signal to the control unit 503, the status indicator light 602 switches to a red flashing mode, and the alarm 603 sounds a tiered alarm. The top of the cabinet 1 is also equipped with a waterproof cover structure, and the speaker of the alarm 603 is angled downwards to ensure effective sound wave propagation. Example 2

[0032] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 9 As shown below, see details: Furthermore, the fixing seat 403 is fixedly installed on the side wall of the mounting bracket 301 by bolts. Two guide posts 404 are set and fixed parallel to each other on the surface of the fixing seat 403. The anti-loosening block 401 is provided with guide holes that cooperate with the guide posts 404 at corresponding positions. The anti-loosening block 401 is slidably sleeved on the two guide posts 404 through the guide holes. The elastic element 402 is a helical spring and is sleeved on the periphery of the guide posts 404. The helical spring is in a pre-compressed state, and its two ends are in close contact with the anti-loosening block 401 and the fixing seat 403 respectively. When the anti-loosening block 401 is squeezed by the locking rod 304, the anti-loosening block 401 slides along the guide post 404 toward the fixing seat 403 and further compresses the helical spring. When the force of the locking rod 304 is eliminated, the restoring force of the helical spring pushes the anti-loosening block 401 to move in the opposite direction along the guide post 404 to return it to its initial position. The contact surface between the anti-loosening block 401 and the locking rod 304 is set as an arc-shaped contact surface to improve the stress state.

[0033] Furthermore, the first guide surface 405 is configured as an outwardly inclined inlet slope, and the second guide surface 406 is configured as an outwardly inclined outlet slope. The included angle between the first guide surface 405 and the second guide surface 406 forms a V-shaped guide structure. The positioning groove 407 is located at the bottom of the V-shaped structure, and its contour is adapted to the body of the locking rod 304. When the locking rod 304 slides along the first guide surface 405, the first guide surface 405 converts the radial pressure of the locking rod 304 into the lateral displacement of the anti-loosening block 401 and compresses the elastic element 402. When the locking rod 304 slides into the positioning groove 407, the elastic element 402 pushes the anti-loosening block 401 to reset, causing the locking rod 304 to be locked into the positioning groove 407. When unlocking is required, the locking rod 304 slides along the second guide surface 406, and the second guide surface 406 again guides the anti-loosening block 401 to compress the elastic element 402, allowing the locking rod 304 to slide smoothly out of the positioning groove 407.

[0034] Furthermore, the operating part 408 is configured as a forward-extending flange structure with anti-slip texture on its surface. The first limiting member 409 and the second limiting member 410 are respectively fixedly installed on opposite sides of the mounting bracket 301, forming a structure that limits the movement range of the operating part 408. When an external force is applied through the operating part 408, the anti-loosening block 401 moves axially along the guide post 404. At this time, the first limiting member 409 and the second limiting member 410 respectively limit the lateral displacement range of the operating part 408, preventing the anti-loosening block 401 from deflecting or getting stuck during movement. A preset gap is maintained between the operating part 408 and the first limiting member 409 and the second limiting member 410. This gap ensures that the anti-loosening block 401 has sufficient travel. At the same time, when the anti-loosening block 401 moves to its limit position, the operating part 408 will contact the first limiting member 409 or the second limiting member 410 to form a hard limit.

[0035] Furthermore, the first mating surface 306 is configured as an inwardly inclined guide slope, and the second mating surface 307 is configured as an outwardly inclined exit slope. The included angle between the first mating surface 306 and the second mating surface 307 forms a V-shaped mating structure. The engaging part 308 is located at the bottom of the V-shaped structure, and its contour is adapted to the positioning groove 407 of the anti-loosening block 401. When the locking rod 304 moves axially, the first mating surface 306 contacts and engages with the first guide surface 405 of the anti-loosening block 401, converting the axial movement of the locking rod 304 into the lateral displacement of the anti-loosening block 401. When the engaging part 308 moves to the position of the positioning groove 407, it achieves locking and positioning under the action of the elastic element 402. When unlocking is required, the locking rod 304 continues to move axially, and the second mating surface 307 contacts and engages with the second guide surface 406 of the anti-loosening block 401, pushing the anti-loosening block 401 to compress the elastic element 402, so that the engaging part 308 smoothly disengages from the positioning groove 407. The locking rod 304 is also provided with a guide groove, which cooperates with the guide pin in the connecting seat 310 to ensure that the locking rod 304 maintains a stable axial movement trajectory during movement.

[0036] Furthermore, the drive component 309 employs an electric push rod and is fixedly mounted to the end of the mounting bracket 301. The connecting seat 310 is fixed to the side of the mounting bracket 301 by bolts, and the locking rod 304 passes through the connecting seat 310 and forms a sliding engagement with it. The rod body of the locking rod 304 is provided with a guide protrusion, and the connecting seat 310 is correspondingly provided with a guide groove that mates with the guide protrusion, ensuring that the locking rod 304 maintains linear motion during movement. When the drive component 309 is activated, its push rod directly acts on the end of the locking rod 304, pushing the locking rod 304 to move along the guide groove of the connecting seat 310 towards the center of the cabinet 1, that is, towards the interior of the mounting bracket 301, so that the locking head 305 at the front end of the locking rod 304 forms a locking engagement with the mating part on the power distribution component 2. The locking rod 304 is also provided with a return spring at its tail. When the driving force of the driving component 309 disappears, the return spring pushes the locking rod 304 to move in the opposite direction along the guide groove of the connecting seat 310 to unlock.

[0037] Furthermore, the auxiliary support 311 adopts an L-shaped bracket structure and is fixed to the end of the guide rail 303 with bolts. The upper surface of the L-shaped bracket is provided with an anti-slip pad layer to support the bottom edge of the power distribution component 2. The cable manager 312 adopts a combination structure of cable management rings and cable tie holders. The cable management rings are mounted on the side columns of the mounting frame 301 via a pivot, and the cable tie holders are evenly distributed on the side beams of the mounting frame 301. The identification plate 313 is fixed to the front crossbeam of the mounting frame 301 with clips. The surface of the identification plate 313 is provided with an information slot into which a printed device parameter card can be inserted. When the power distribution component 2 is pushed in along the guide rail 303, its bottom edge contacts the anti-slip pad layer of the auxiliary support 311 to form auxiliary support. The cable management ring of the cable manager 312 can be rotated open to accommodate the cable bundle. The cable tie holders work with the cable ties to fix the cable bundle routing. The identification plate 313 faces the operating direction for easy viewing of device information.

[0038] Furthermore, the centrifugal fan 501 is fixed to the inside of the top plate of the cabinet 1 by a mounting bracket, with its air outlet facing the outside of the cabinet 1. The temperature detector 502 is a thermistor sensor and is distributed near each heat-generating element inside the cabinet 1. The control unit 503 is installed in a protective box on the side wall of the cabinet 1. When the temperature detector 502 detects that the internal temperature of the cabinet 1 has reached a set threshold, it transmits a signal to the control unit 503. The control unit 503 then starts the centrifugal fan 501. The impeller of the centrifugal fan 501 rotates to generate negative pressure, which exhausts the hot air inside the cabinet 1 through the top air outlet, while cold air flows in through the bottom air inlet of the cabinet 1 to form convection.

[0039] Preferably, the ventilation grille 504 is installed at the bottom of the side wall, thus serving as an air inlet. Under negative pressure, external cold air enters the cabinet 1 through the ventilation grille 504, forming convection.

[0040] When the temperature sensor 502 detects that the temperature has dropped to a safe range, the control unit 503 delays the shutdown of the centrifugal fan 501 according to a preset program to ensure effective heat dissipation. The motor speed of the centrifugal fan 501 can be adjusted in stages by the control unit 503 according to temperature changes, achieving intelligent temperature control management.

[0041] Furthermore, the ventilation grille 504 adopts a louvered structure and is embedded in the lower part of the side wall of the cabinet 1. The filter structure 505 is a removable fiber filter screen and is fixed to the inner surface of the ventilation grille 504 with clips. The air guide shroud 506 adopts a gradually expanding horn-shaped structure and is connected to the air outlet of the centrifugal fan 501. When the centrifugal fan 501 is working, the outside air of the cabinet 1 enters through the louvered gaps of the ventilation grille 504 under negative pressure, and removes dust and impurities through the fiber filter screen of the filter structure 505. The clean air forms an upward airflow channel inside the cabinet 1, and finally, the hot air is evenly discharged through the gradually expanding channel of the air guide shroud 506 driven by the centrifugal fan 501. The gradually expanding structure of the air guide shroud 506 can reduce the air outlet resistance and guide the hot airflow away from the top surface of the cabinet 1. The filter structure 505 can be periodically removed from the ventilation grille 504 for cleaning and maintenance to ensure the continuous working efficiency of the heat dissipation system 5.

[0042] Furthermore, the access control sensor 601 is a Hall sensor embedded in the sealing groove of the cabinet 1 door frame. The status indicator light 602 is a tri-color LED light group mounted on the upper right corner of the front door of the cabinet 1 via a waterproof base. The alarm 603 is an audible and visual alarm, fixed to the top of the cabinet 1 under the rain cover by a bracket. When the cabinet 1 door is opened, the magnetic field change of the access control sensor 601 triggers a switch signal. This signal is transmitted to the control unit 503, which synchronously drives the status indicator light 602 to change from green to flashing red, and simultaneously activates the alarm 603, emitting a buzzer alarm and a rotating flashing light. When the door is closed, the access control sensor 601 detects the recovery of the magnetic signal, and the control unit 503 controls the status indicator light 602 to return to a constant green state and shuts off the alarm 603. The surface of the status indicator light 602's lampshade has a scattering pattern to expand the visibility range, and the sound pressure level of the alarm 603 can be adjusted according to the installation environment.
