[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] As Figure 1 - Figure 2 shown, a safety performance detection device for a power distribution cabinet provided by the present invention includes: a power distribution cabinet body 100, a fan 200, an air inlet assembly 300, a driving member 400, and an air outlet assembly 500.

[0020] As Figure 1 shown, the power distribution cabinet body 100 is used for power distribution, control, and protection of the power system, which is a conventional prior art.

[0021] Continuing as Figure 1 shown, the fan 200 is fixed to the power distribution cabinet body 100 and can supply air to the inside of the power distribution cabinet body 100, which is a conventional prior art.

[0022] Continuing as Figure 1 shown, the air inlet assembly 300 is fixed to the fan 200 and is used to adjust the air inlet speed. The specific implementation method is as follows: As Figure 4As shown, the air inlet assembly 300 includes: a first housing 310, a plurality of first air inlets 320, a first threaded rod 330, a first sliding plate 340, a plurality of second air inlets 350, and a plurality of third air inlets 360.Among them, the first housing 310 is rectangular, with a rectangular groove opened at the bottom, and the first housing 310 is fixed to the fan 200; several first air inlets 320 are long strip-shaped notches, and the several first air inlets 320 are equidistantly arranged on the first housing 310, enabling the wind force of the fan 200 to enter the power distribution cabinet body 100 through the several first air inlets 320; the first threaded rod 330 is a long strip-shaped column, with a threaded groove opened on the outer wall, and the first threaded rod 330 sequentially penetrates through the first housing 310 and the power distribution cabinet body 100 and is rotatably connected to the first housing 310 and the power distribution cabinet body 100. The driving member 400 is connected to the first threaded rod 330, and the driving member 400 can drive the first threaded rod 330 to rotate. When the first threaded rod 330 rotates, it can drive the first slide plate 340 to slide and move along the rectangular groove inside the first housing 310; the first slide plate 340 is a rectangular plate structure, the first slide plate 340 is threadedly connected to the first threaded rod 330, and the first slide plate 340 is arranged inside the first housing 310 and is slidably connected to the first housing 310. When the first slide plate 340 moves, it can synchronously drive several second air inlets 350 and several third air inlets 360 to move; several second air inlets 350 are long strip-shaped notches, and the several second air inlets 350 are equidistantly arranged on the first slide plate 340. The several second air inlets 350 correspond to and are adapted to the several first air inlets 320. In the initial state, the wind force entering the several first air inlets 320 can normally enter the power distribution cabinet body 100 through the several second air inlets 350. When the first slide plate 340 drives the several second air inlets 350 to move, the several second air inlets 350 will be misaligned with the several first air inlets 320, and the wind force of the several first air inlets 320 can no longer normally pass through the several second air inlets 350; several third air inlets 360 are long strip-shaped notches, and the several third air inlets 360 are sequentially and equidistantly arranged between the several second air inlets 350. The size of the several third air inlets 360 is smaller than that of the several second air inlets 350. In the initial state, the several third air inlets 360 are misaligned with the several first air inlets 320, and the several first air inlets 320 cannot send air through the several third air inlets 360. When the first slide plate 340 drives the several third air inlets 360 to move and makes the several third air inlets 360 and the several first air inlets 320 overlap, the several first air inlets 320 can send air through the several third air inlets 360. Also, because the size of the several third air inlets 360 is smaller, according to the formula Q = v * A (Q is the flow rate, v is the flow velocity, A is the flow cross-sectional area), when the air volume remains unchanged, reducing the cross-sectional area of the air outlet will increase the flow velocity, which can increase the flow velocity to quickly dissipate heat when the temperature inside the power distribution cabinet rises rapidly, so as to maintain the safety of the power distribution cabinet.

[0023] Continue as Figure 1As shown, the driving member 400 is connected to the air inlet assembly 300 and can drive the first threaded rod 330 to rotate. The driving member 400 has two embodiments: In the first embodiment, the driving member 400 is a self-locking motor, which is fixed to the power distribution cabinet body 100. The output end of the self-locking motor is fixed to the first threaded rod 330. By starting the self-locking motor, the first threaded rod 330 is driven to rotate automatically, making the device more automatic.

[0024] In the second embodiment, the driving member 400 is a knob, which is fixed to the first threaded rod 330. The user can drive the first threaded rod 330 to rotate by manually rotating the knob. This method can make the device more energy-saving.

[0025] Continue as Figure 1 As shown, the air outlet assembly 500 is fixed to the power distribution cabinet body 100 and is used for air outlet. The specific implementation is as follows: As Figure 5 As shown, the air outlet assembly 500 includes: a second housing 510, a first air outlet 520, a second threaded rod 530, a second slide plate 540, and a plurality of second air outlets 550. Among them, the second housing 510 is rectangular, and a rectangular groove is opened at the bottom. The second housing 510 is fixed inside the power distribution cabinet body 100; the first air outlet 520 is a square opening, which is opened on the second housing 510 and can allow the heat-carrying air to pass through; the second threaded rod 530 is a long strip-shaped column, and a thread groove is opened on the outer wall. The second threaded rod 530 sequentially passes through the second housing 510 and the power distribution cabinet body 100 and is rotatably connected to the second housing 510 and the power distribution cabinet body 100. When the second threaded rod 530 rotates, it can drive the second slide plate 540 to slide and move along the rectangular groove inside the second housing 510; the second slide plate 540 is a rectangular plate-like structure, which is threadedly connected to the second threaded rod 530. The second slide plate 540 is arranged inside the second housing 510 and is slidably connected to the second housing 510. When the second slide plate 540 is driven to move by the second threaded rod 530, the second slide plate 540 will gradually move away from the first air outlet 520, opening the first air outlet 520, increasing the air outlet, allowing the hot air to be discharged faster, and improving the heat dissipation effect; the plurality of second air outlets 550 are long strip-shaped through grooves, which are sequentially opened on the second slide plate 540. The plurality of second air outlets 550 can allow the hot air to flow out from the plurality of second air outlets 550. In the initial state, the second slide plate 540 completely covers the first air outlet 520, and only the hot air can be discharged through the plurality of second air outlets 550. After the movement of the second slide plate 540 is completed, the hot air can be discharged through the first air outlet 520 with all its strength for heat dissipation.

Among them, the first pulley 610 is cylindrical, and a groove for accommodating the transmission belt 630 is provided on the outer wall along the circumferential direction. The first pulley 610 is fixed to the first threaded rod 330, so that the first pulley 610 can be driven to rotate by the first threaded rod 330; the second pulley 620 is cylindrical, and a groove for accommodating the transmission belt 630 is provided on the outer wall along the circumferential direction. The second pulley 620 is fixed to the second threaded rod 530. The second pulley 620 can be driven to rotate by the first pulley 610 through the transmission belt 630. At the same time, the second pulley 620 drives the second threaded rod 530 to rotate; the transmission belt 630 (also called a belt or a transmission belt) is a component used in a mechanical transmission system, and mainly transmits power through the friction between the pulley and the belt. The transmission belt 630 is in transmission connection with the first pulley 610 and the second pulley 620, and can synchronously drive the first pulley 610 and the second pulley 620.

[0027] Continue as Figure 1 As shown in Figure 1 , a temperature sensor 700 is fixedly connected to the second housing 510. The temperature sensor 700 is used to detect the temperature inside the power distribution cabinet body 100 to ensure the safety of the power distribution cabinet body 100.
