Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, specifically a power distribution cabinet for smart grids. Background Technology

[0002] A distribution cabinet (also called a distribution panel, distribution box, or distribution cabinet) is an important piece of equipment in a power system, primarily used for receiving, distributing, and controlling the flow of electricity. It is commonly used in industrial, commercial, and residential buildings to ensure a stable power supply, guarantee the safe operation of equipment, and provide necessary protection functions. A distribution cabinet typically consists of multiple electrical components, such as circuit breakers, disconnect switches, contactors, ammeters, and voltmeters.

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.

[0029] This invention provides the following technical solutions:

[0030] Example 1

[0031] Please see Figures 1-6A smart grid distribution cabinet includes a cabinet body 1, a door 2 on the front side of the cabinet body 1, a heat dissipation vent 8 on the rear side of the cabinet body 1, multiple heat dissipation plates 9 fixedly connected to the inner side of the heat dissipation vent 8, a rain cover 3 fixedly connected to the upper side of the cabinet body 1, a sealing unit 4 on the rear side of the cabinet body 1, the sealing unit 4 including a shielding component 43 for shielding the heat dissipation vent 8, two fixing plates 5 fixedly connected to the rear side of the cabinet body 1, two wiring holes 10 on the lower side of the cabinet body 1, and a sealing component 44 for sealing the wiring holes 10 on the lower side of the cabinet body 1. A stabilizing component 45 is provided on the front side to limit the position of the cabinet door 2. Two support frames 41 are fixedly connected to the lower side of the distribution cabinet body 1. Side plates 42 are fixedly connected to the outer sides of the two support frames 41. A rear plate 7 is fixedly connected to the rear side of one of the fixed plates 5. A protective plate 6 is fixedly connected to the front side of both fixed plates 5. The protective plate 6 has a triangular structure, which facilitates the protection of the side of the distribution cabinet body 1. The components of the sealing unit 4 are protected by the rear plate 7. The electronic components inside the distribution cabinet body 1 are vented through the heat dissipation vent 8 and multiple heat dissipation plates 9. The internal connecting wires are passed through the wiring hole 10 to connect to external equipment.

[0032] The shielding assembly 43 includes a slide groove 431, which is located on one side of the two fixed plates 5 near the heat dissipation vent 8. Two symmetrically distributed sliders 432 are slidably connected to the inner side of the slide groove 431. A shielding plate 433 is fixedly connected to the front side of each slider 432. Lifting grooves 434 are provided on the outer sides of both side plates 42. A moving block 435 is slidably connected to the inner side of the lifting groove 434. A lifting plate 436 is fixedly connected to the outer side of the moving block 435. A floating plate 437 is fixedly connected to the lower side of each of the two lifting plates 436. A spring 438 is fixedly connected between the distribution cabinet body 1 and the moving block 435. An L-shaped block 4315 is fixedly connected to the front side of each slider 432. The front side of 315 is rotatably connected to inclined plate 2 4316. A rotating block 4317 is rotatably connected to the outer side of the lower end of inclined plate 2 4316. A lifting block 2 4318 is fixedly connected to the lower side of rotating block 4317. Rectangular slots 1 4319 are provided on both the left and right sides of lifting block 2 4318. An inclined plate 3 4320 is rotatably connected to the inner side of rectangular slot 1 4319. The rear side of the distribution cabinet body 1 is rotatably connected to two central shafts 4313. A rotating plate 4314 is fixedly connected to the rear end of each of the two central shafts 4313. Inclined plate 3 4320 is rotatably connected to rotating plate 4314. An inclined plate 1 4312 is rotatably connected to the outer side of the lower end of rotating plate 4314. A control block 4311 is rotatably connected to the outer side of inclined plate 1 4312. A lifting block 4310 is fixedly connected to the lower side of 311. A control rod 439 is fixedly connected between the lifting block 4310 and the lifting plate 436. A rear block 4322 is fixedly connected to the rear side of the distribution cabinet body 1. A sliding rod 4321 is fixedly connected between the rear block 4322 and the fixed plate 5. The sliding rod 4321 is slidably connected to the lifting block 4318. When there is heavy rain outside, the water on the ground increases. As the water level rises, the floating plate 437 rises. The floating plate 437 raises the lifting plate 436. The lifting plate 436 raises the control rod 439. The control rod 439 raises the lifting block 4310. The lifting block 4310 raises the inclined plate 431 on the control block 4311. 2. The first inclined plate 4312 drives the rotating plate 4314 to rotate, the rotating plate 4314 drives the third inclined plate 4320 to rotate, the third inclined plate 4320 drives the second lifting block 4318 to descend, the second lifting block 4318 drives the second inclined plate 4316 to rotate. Since the two second inclined plates 4316 are symmetrically distributed, the second inclined plate 4316 drives the L-shaped block 4315 to move. The L-shaped blocks 4315 on both sides move closer to each other. The L-shaped blocks 4315 drive the slider 432 to move, the slider 432 drives the baffle plate 433 to move. The two baffle plates 433 move closer to each other, which facilitates the baffle plates 433 on both sides to block the heat dissipation port 8, and prevent external water from entering the power distribution cabinet body 1 through the heat dissipation port 8 and affecting the use of the internal electronic components.

[0033] Example 2

[0034] Based on Example 1, such as Figure 7 As shown, the sealing assembly 44 includes an airbag 448, which is fixedly connected to the inner side of two wire holes 10. A connecting pipe 447 is fixedly connected between the two airbags 448. A mounting groove 443 is provided in the middle of the bottom side of the distribution cabinet body 1. An air cylinder 445 is fixedly connected to the inner side of the mounting groove 443. A piston disc 444 is provided inside the air cylinder 445. A connecting plate 441 is fixedly connected between the two lifting plates 436. A lifting rod 442 is fixedly connected between the connecting plate 441 and the piston disc 444. The air cylinder 445 and the connecting pipe 447 are connected... A delivery pipe 446 is fixedly connected between the two parts. When external water causes the lifting plate 436 to rise, the lifting plate 436 causes the connecting plate 441 to rise, the connecting plate 441 causes the lifting rod 442 to rise, the lifting rod 442 causes the piston disc 444 to rise, and the piston disc 444 pushes the gas in the air cylinder 445 out. The gas is then delivered to the two air bags 448 through the delivery pipe 446 and the connecting pipe 447, causing the air bags 448 to inflate. This facilitates the sealing of the wiring hole 10, preventing external water from entering the distribution cabinet body 1 through the wiring hole 10.

[0035] Example 3

[0036] Based on Example 1, such as Figures 8-10 As shown, two slots 451 are provided on the lower side of the door 2. A front block 454 is fixedly connected to the front side of the lifting plate 436. Two mounting plates 453 are provided on the outer side of the front block 454. A plug box 452 adapted to the slot 451 is fixedly connected between the two mounting plates 453. A pin 455 is provided between the mounting plate 453 and the front block 454. When the lifting plate 436 rises, the lifting plate 436 drives the front block 454 to rise, the front block 454 drives the mounting plate 453 to rise, and the mounting plate 453 drives the plug box 452 to rise, so that the plug box 452 can be inserted into the slot 451, which facilitates the initial positioning of the door 2, increases the stability of the door 2, and prevents the door 2 from being opened accidentally by external storms. When it is necessary to open the door 2, the pin 455 is pulled out, and the mounting plate 453 and the plug box 452 are removed for normal maintenance.

[0037] Contact blocks 456 are provided on both the left and right sides of the insertion box 452. Movable blocks 457 are fixedly connected to the outer sides of both contact blocks 456. Rectangular grooves 458 are formed on the outer sides of the movable blocks 457. Inclined plates 459 are rotatably connected to the inner sides of both rectangular grooves 458. A connecting block 4510 is rotatably connected to the outer side of the upper end of the inclined plates 459. A pressing block 4511 is fixedly connected to the upper side of the connecting block 4510. A pressing rod 4512 is fixedly connected to the upper side of the pressing block 4511. The upper end of the pressing rod 4512 passes through the upper side of the insertion box 452 and is fixedly connected to a pressing plate 4513. The pressing plate 4513 and the insertion box 452 are connected... A fixed connection is provided with spring 4514. When the insert box 452 is inserted into the slot 451, the insert box 452 drives the pressing plate 4513 to contact the inner wall of the slot 451. The insert box 452 continues to rise, causing the pressing plate 4513 to drive the pressing block 4511 on the pressing rod 4512 to fall. The pressing block 4511 drives the inclined plate 459 to rotate. Since the two inclined plates 459 are symmetrically distributed, the moving blocks 457 on both sides move away from each other. The moving blocks 457 drive the contact block 456 to move. The contact blocks 456 on both sides move away from each other, so that the contact block 456 contacts the inner wall of the slot 451, which facilitates the increased limiting effect of the insert box 452 on the door 2.

[0038] Working Principle: During use, the external protective plates 6 and rear plate 7 protect the main body of the distribution cabinet 1. In heavy rain, the accumulated water on the ground causes the floating plate 437 to lift the lifting plate 436. Under the action of the control rod 439, lifting block 1 4310, control block 4311, inclined plate 1 4312, rotating plate 4314, and inclined plate 3 4320, the lifting block 2 4318 is controlled to descend. Under the action of inclined plate 2 4316, L-shaped block 4315, and slider 432, the left and right side shielding plates 433 are controlled to move closer together, facilitating the shielding plates 433 to block the heat dissipation vent 8, preventing external water from entering the main body of the distribution cabinet 1 through the heat dissipation vent 8. Simultaneously, the lifting plate 436 drives the connecting... As plate 441 rises, the airbag 448 expands under the action of lifting rod 442, piston disc 444, air cylinder 445, delivery pipe 446, and connecting pipe 447, facilitating the sealing of the wiring hole 10 and preventing water from entering the distribution cabinet body 1 through the wiring hole 10. At the same time, under the action of front block 454, mounting plate 453, and plug box 452, the plug box 452 is controlled to insert into the slot 451 on the cabinet door 2, facilitating the reinforcement of the cabinet door 2 and preventing the cabinet door 2 from being opened accidentally. Meanwhile, under the action of pressing plate 4513, pressing rod 4512, pressing block 4511, inclined plate four 459, and moving block two 457, the contact blocks 456 on both sides are controlled to contact the slot 451, increasing the stability of the connection.
