Description

Technical Field

[0001] The utility model relates to the technical field of control cabinets, in particular to an electric automation control cabinet. Background Art

[0002] After searching, the Chinese patent publication number is CN216750901U, and the publication date is 2022-06-14. It discloses an electrical automation control cabinet, including a cabinet, and the inner walls of the cabinet are fixedly connected to side panels on both sides, and the top of the side panels is fixedly connected to a top panel. An airflow duct is formed on the side of the control cabinet through the side panels and the cabinet. When the air flow in the cabinet is blocked, it can enter the interlayer duct between the side panels and the cabinet through the air vents to circulate, so that the air circulation in the cabinet is smoother and the heat dissipation efficiency is accelerated. By setting the air inlet at a higher place, when water accumulates on the ground near the cabinet, it can avoid entering the cabinet from the air inlet, and it can also avoid the situation where the gravity of the air inlet attracts dust on the ground. The first dustproof net blocks dust and garbage near the air inlet. However, the existing control cabinet needs to use a fan to ventilate the interior of the control cabinet to ensure that the interior of the control cabinet is in a low temperature environment. After the fan continuously ventilates, the temperature inside the control cabinet will tend to be stable. The long-term continuous operation of the fan will not only increase power consumption, but also shorten the service life. In addition, the air inlet is always in an open state, which will cause too much dust to enter the electrical components in the control cabinet, affecting the normal operation of the electrical components.

When the temperature sensor detects that the temperature inside the cabinet 1 rises to a critical value, the air inlet 2 and the exhaust port 3 are all opened, and the ventilation fan assembly 7 works. When the temperature sensor detects that the temperature inside the cabinet 1 tends to be stable, the air inlet 2 and the exhaust port 3 are closed, and the ventilation fan assembly 7 stops working. A fixing block 4 is fixedly connected to one side of the inner wall of the cabinet 1, and a blocking mechanism 5 and a driving mechanism 6 are respectively arranged on the cabinet 1; the blocking mechanism 5 includes a shielding cover 51 and an upper baffle 52, and the shielding cover 51 is fixedly connected to the cabinet 1, and one side of the shielding cover 51 penetrates A through hole 53 is penetrated, and the through hole 53 is in the same straight line as the exhaust port 3. A lower baffle 54 is slidably connected to one side of the shielding cover 51, and the upper baffle 52 is slidably connected to the inner wall of the cabinet 1. The upper baffle 52 and the lower baffle 54 are connected to the driving mechanism 6 through a transmission mechanism 55. The cabinet 1 is ventilated by using the ventilation fan assembly 7. When the internal temperature of the cabinet 1 tends to be stable, the ventilation fan assembly 7 is properly closed, and the driving mechanism 6 and the transmission mechanism 55 are used to drive the upper baffle 52 and the lower baffle 54 to move, so as to close the air inlet 2 and the through hole 53, thereby preventing dust from entering the cabinet 1. Not only the working time of the ventilation fan assembly 7 is reduced and the service life is increased, but also the amount of dust entering the cabinet 1 can be reduced, which is beneficial to the normal operation of electrical components.

[0025] The driving mechanism 6 includes a motor 61, which is electrically connected to an external power supply and cooperates with a temperature sensor and a ventilation fan assembly 7 arranged inside the cabinet 1. The motor 61 is fixedly connected to the outside of the cabinet 1, and a rotating rod 62 is fixedly connected to the motor 61. One end of the rotating rod 62 passes through the cabinet 1 and extends into the interior of the cabinet 1. A driving bevel gear 63 is fixedly connected to the rotating rod 62, and two driving bevel gears 63 are provided.

[0026] A ventilation fan assembly 7 is fixedly connected to the other side of the shielding cover 51. The ventilation fan assembly 7 is electrically connected to an external power supply and cooperates with a temperature sensor and a motor 61 provided inside the cabinet 1. A protective cover 8 is fixedly connected to one side of the cabinet 1 and located outside the motor 61.

[0027] The transmission mechanism 55 includes a first screw rod 551 and a second screw rod 552. The first screw rod 551 is rotatably connected in the cabinet 1. The first screw rod 551 is threadedly connected with a first connecting block 553. The first connecting block 553 is fixedly connected to the lower baffle 54.

[0028] A straight rod 14 is fixedly connected in the cabinet body 1, and a second connecting block 15 is slidably connected to the straight rod 14. The second connecting block 15 is fixedly connected to the lower baffle 54. The coordinated use of the straight rod 14 and the second connecting block 15 is beneficial to the movement stability of the lower baffle 54.

[0029] Embodiment 2

[0030] Based on Example 1, see Figure 1 , Figure 3 and Figure 5 Shown

[0031] Both sides of the inner wall of the cabinet 1 are fixedly connected with fixing rods 9, and a slide seat 10 is slidably connected to the fixing rods 9. A placement box 11 is fixedly connected to the slide seat 10, and a threaded rod 12 is threadedly connected to the slide seat 10. One side of the fixing rod 9 is provided with a plurality of threaded holes 13 adapted to the threaded rod 12. Through the coordinated use of the fixing rod 9, the slide seat 10, the placement box 11, the threaded rod 12 and the threaded holes 13, some desiccants can be placed on the placement box 11 to dry the inside of the cabinet 1. At the same time, the position of the placement box 11 is adjusted on the fixing rod 9 to ensure that the desiccants in the plurality of placement boxes 11 cooperate with each other to improve the drying efficiency.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] The working principle of the utility model is as follows: through the action of the ventilation fan assembly 7, in combination with the use of the air inlet 2 and the exhaust port 3, the air inside the cabinet 1 is ventilated, thereby discharging the hot air inside the cabinet 1. As the ventilation fan assembly 7 continuously ventilates, the temperature inside the cabinet 1 gradually tends to a stable state, so that the temperature sensor detects the temperature change, and then the ventilation fan assembly 7 stops working, and the motor 61 starts working, and then drives the driving bevel gear 63 to rotate through the rotating rod 62, and utilizes the cooperation between the driving bevel gear 63 and the driven bevel gear 554 to respectively drive the first screw rod 551 and the second screw rod 552 to rotate, and then can respectively drive the lower baffle plate 54 and the upper baffle plate 52 to move, so that the lower baffle plate 54 blocks the through hole 53, thereby blocking the exhaust port 3, and the upper baffle plate 52 blocks the air inlet 2, which can prevent dust from entering the cabinet 1. This not only shortens the working time of the ventilation fan assembly 7 and improves its service life, but also reduces the amount of dust entering the cabinet 1, which is beneficial to the normal operation of electrical components. When the temperature sensor detects that the temperature inside the cabinet 1 rises to a critical value, the lower baffle 54 and the upper baffle 52 will be reset, and the ventilation fan assembly 7 will work again to ventilate the inside of the cabinet 1. In addition, some desiccant can be placed on the placement box 11 to dry the inside of the cabinet 1. At the same time, the position of the placement box 11 is adjusted on the fixing rod 9 to ensure that the desiccants in the multiple placement boxes 11 are used in coordination with each other to improve the drying efficiency.
