[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 10 In this embodiment, an intelligent electrical control cabinet for environmental protection facilities is provided, including a cabinet body 1, a cabinet door 3 is connected to the front side of the cabinet body 1, a partition 5 is fixedly connected inside the cabinet body 1, a gap is formed between one end of the partition 5 and the back side of the cabinet body 1, a movable plate 51 is slidably connected inside the partition 5, one end of the movable plate 51 contacts the back side of the cabinet body 1, mounting plates 4 are fixedly connected to the upper and lower sides of the partition 5 inside the cabinet body 1, a plurality of vents 42 are opened on the mounting plates 4, and a closing plate 44 for opening and closing the vents 42 is slidably connected to one side of the mounting plates 4, a cooling fan 1 6 is installed on the upper and lower sides of the cabinet body 1, and a cooling fan 2 7 is installed on the back side of the cabinet body 1 above and below the partition 5;

[0037] Air outlets 2 are provided on both sides of the cabinet 1 , and adjustment plates 12 for adjusting the size of the air outlets 2 are slidably connected to both sides of the cabinet 1 .

[0038] The interior of the cabinet 1 is divided into two parts, an upper part and an lower part, by using a partition 5. By installing electrical components that often do not work together in the upper and lower parts respectively, the heat dissipation inside the cabinet 1 is more concentrated, which is convenient for the main heat dissipation.

[0039] Air flow is sucked in by the cooling fan 2 7 and the cooling fan 1 6 on the cabinet 1 , and the air flow passes through the interior of the cabinet 1 and is taken away through the air outlet 2 .

[0040] Airflow is sucked in by the cooling fan 2 7, and enters the side of the mounting plate 4 through the vent 42, taking away the heat generated by the electrical components installed on the side of the mounting plate 4 when working, and the hot airflow is discharged through the air outlets 2 on both sides. Airflow is sucked in from the upper and lower sides of the cabinet 1 by the cooling fan 1 6, and the airflow enters the interior of the cabinet 1 and takes away the heat through the air outlets 2.

[0041] When the partition 5 moves, the upper and lower closing plates 44 can be pushed to open and close the vents 42 in different states, so that the cooling fan 27 on one side of the cabinet 1 can sense the temperature inside the upper and lower spaces of the partition 5. When the temperature of the space above the partition 5 or the space below the partition 5 is high, the two cooling fans 27 can be aligned to dissipate heat, thereby improving its heat dissipation capacity under high load.

[0042] In this embodiment, refer to Figure 2 Specifically, a plurality of mounting rails 41 for mounting electrical components are mounted on the mounting plate 4, and the mounting rails 41 and the vents 42 are spaced apart from each other.

[0043] A plurality of electrical components are mounted on the mounting plate 4 through the guide rails 41 and arranged through the guide rails 41 so that the electrical components are evenly located between the vents 42 , making the arrangement of the electrical components neat and more conducive to heat dissipation.

[0044] In this embodiment, refer to Figures 5 to 7 Specifically, both sides of one end of the movable plate 51 are slidably connected to the lifting frame 52, and the upper end of the lifting frame 52 is rotatably connected to the pushing rod 53, one end of the pushing rod 53 and the lower end of the closing plate 44 on the upper mounting plate 4 are located in the same longitudinal plane, and the pushing rod 53 can contact the closing plate 44 after the movable plate 51 moves, and the lower end of the lifting frame 52 is slidably connected to the lifting rod 58, one end of the lifting rod 58 and the upper end of the closing plate 44 on the lower mounting plate 4 are located in the same longitudinal plane, and the lifting rod 58 is always in contact with the closing plate 44, and an insertion block 45 is fixedly connected to the back side of the lower mounting plate 4, and the insertion block 45 and the lifting frame 52 are located in the same longitudinal plane, and an insertion port 57 is opened on the lifting frame 52, and one end of the insertion block 45 can be inserted into the insertion port 57, and one end of the insertion block 45 and the inside of the insertion port 57 are both provided with inclined surfaces.

[0045] By retracting the movable plate 51 into the interior of 5, the movable plate 51 drives the lifting frame 52 to move together. When the pushing rod 53 on the lifting frame 52 moves, it is blocked by the mounting plate 4 and rotates upward. At the same time, one end of the pushing plate 53 moves upward along the mounting plate 4, and one end of the pushing plate 53 pushes the upper closing plate 44 to move upward. The closing plate 44 blocks the upper vent 42. The airflow drawn in from one side of the cabinet 1 can only enter the space below the partition 5 through the lower vent 42, thereby concentratedly cooling the area below the partition 5.

[0046] The movable plate 51 continues to move. At this time, the upper end of the insertion block 45 is inserted into the lower end of the insertion opening 57, and one end of the insertion block 45 is gradually inserted into the insertion opening 57, so that the lifting frame 52 descends. When the lifting frame 52 descends, the lower end of the lifting frame 52 drives the lifting rod 58 to descend together. The lifting rod 58 thereby descends, causing the lower closing plate 44 to descend and block the lower vent 42. The pushing rod 53 at the upper end of the lifting frame 52 then descends, and the upper closing plate 44 on the pushing rod 53 loses support and descends together. After the upper closing plate 44 descends, the upper vent 42 is opened, and the airflow drawn in from one side of the cabinet 1 can only enter the space above the partition 5 through the upper vent 42, thereby centrally dissipating the heat above the partition 5.

[0047] In this embodiment, refer to Figure 6 Specifically, a connecting rod 54 is fixedly connected to the bottom of the movable plate 51, a connecting block 55 is fixedly connected to one side of the lifting frame 52, the connecting rod 54 passes through the connecting block 55, and a spring 56 is provided between the lower end of the connecting rod 54 and the connecting block 55, and the elastic force of the spring 56 is greater than the weight of the upper closing plate 44.

[0048] The connecting block 55 is slidably connected to the connecting rod 54, thereby compressing the spring 56 during the descent, ensuring that the lifting frame 52 can be reset after the movable plate 51 is extended. At the same time, the elastic force of the spring 56 is much greater than the upper closing plate 44, thereby ensuring that 53 can push the closing plate 44 upward before it descends.

[0049] In this embodiment, refer to Figure 7 Specifically, a limit block 59 is provided at the upper end of the lifting frame 52 below the push rod 53. The limit block 59 allows one end of the push rod 53 to always tilt upward, so that it can be restricted by the mounting plate 4 after moving and can rotate upward, thereby pushing the upper closing plate 44.

[0050] In this embodiment, refer to Figure 5 Specifically, a plurality of guide plates 43 are installed on the back side of the mounting plate 4, the guide plates 43 are adjacent to the vents 42, and the guide plates 43 are horizontal and perpendicular to the mounting plate 4.

[0051] The guide plates 43 are used to block the airflow after it flows, so that it is easier for the airflow to enter the side of the partition 5 through the vents 42 . The upper and lower adjacent guide plates 43 are staggered to ensure that the airflow can reach the side of multiple vents 42 .

[0052] In this embodiment, refer to Figures 9-10Specifically, sliding grooves 11 are fixedly connected on both sides of the cabinet 1, and the adjusting plate 12 is slidably connected inside the sliding grooves 11. The lower end of the adjusting plate 12 is fixedly connected to a connecting frame 13, and the lower end of the connecting frame 13 is located inside the partition 5. The movable plate 51 is located inside the partition 5, and the upper and lower sides of one end are fixedly connected to push blocks 511. The end of the pushing block 511 close to the connecting frame 13 is a curved surface, and the two ends of the connecting frame 13 are inclined surfaces.

[0053] The adjusting plate 12 slides up and down through the sliding groove 11. When one end of the movable plate 51 is retracted into the interior of the partition 5, the movable plate 51 drives the pushing block 511 to move together. The curved surface at one end of the pushing block 511 contacts the inclined surface at one end of the connecting frame 13. The connecting frame 13 moves to the upper and lower sides through the squeezing of the pushing block 511. The movement of the connecting frame 13 drives the adjusting plates 12 on the upper and lower sides to move. The movement of the adjusting plate 12 opens the blocked cross-section of the air outlet 2, thereby increasing the air outlet area on both sides of the cabinet 1 and improving the heat dissipation and air outlet capacity of the cabinet 1.

[0054] In this embodiment, refer to Fig.10 Specifically, a telescopic cylinder 510 is fixedly installed inside the partition 5, and one end of the telescopic cylinder 510 is fixedly connected to the movable plate 51.

[0055] The telescopic cylinder 510 is extended and retracted to drive the movable plate 51 to move, so that the movable plate 51 can be extended or retracted into the interior of the partition plate 5 .

[0056] In this embodiment, specifically, elastic supports are provided between the adjustment plate 12 located below the partition 5 and the closing plate 44 located below the partition 5 and the bottom end of the cabinet 1 .

[0057] The adjusting plate 12 and the closing plate 44 are supported by elastic supports to ensure that they can overcome gravity and maintain a set height.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
