[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0036] Please refer to the attached Figures 1 to 9 A moisture-proof electrical cabinet according to an embodiment of the present invention is described in detail.

[0037] like Figures 1 to 3As shown, a moisture-proof electrical cabinet 100 according to an embodiment of the present invention includes a cabinet 1, a control assembly 2, fans 3, and a sealing assembly 4. The cabinet 1 is provided with m air vents, where m ≥ 2. The control assembly 2 includes a first humidity sensor 21, a second humidity sensor 22, and a controller 23. The first humidity sensor 21 is provided inside the cabinet 1 and is used to monitor the humidity inside the cabinet 1. The second humidity sensor 22 is provided outside the cabinet 1 and is used to monitor the humidity outside the cabinet 1. Both the first humidity sensor 21 and the second humidity sensor 22 are electrically connected to the controller 23. The fans 3 are provided at the air vents. The wind direction formed by at least one of the m fans 3 in the m air vents is different, that is, the wind direction of the air inlet or outlet formed by at least one of the m fans 3 in the cabinet 1 is different from that of the other fans 3. The sealing assembly 4 is provided at the air vents, and there are also m sealing assemblies 4. The sealing assembly 4 includes a baffle 41 and a driving member 42. The baffle 41 is movably provided on the cabinet 1 and has an open position and a closed position. In the closed position, the baffle 41 seals the air outlet where it is located. In the open position, the baffle 41 is separated from at least a part of the air outlet where it is located so that air can flow through the air outlet. The driving member 42 is provided on the cabinet 1. The driving member 42 is electrically connected to the controller 23. The driving member 42 is connected to the baffle 41 to drive the baffle 41 to move between the open position and the closed position.

[0038] Under normal conditions, the baffle 41 is in the closed position, the air outlet is in a closed state, the cabinet 1 is in a closed state, and the air inside and outside the cabinet 1 does not circulate. When the first humidity sensor 21 detects that the humidity inside the cabinet 1 is higher than the set threshold, and the humidity detected by the first humidity sensor 21 is higher than the humidity detected by the second humidity sensor 22, that is, when the humidity inside the cabinet 1 is greater than the humidity outside the cabinet 1, the controller 23 controls the driving member 42 to drive the baffle 41 from the closed position to the open position, exposing the air outlet, and then the controller 23 controls the fan 3 to turn on. The fan 3 drives the air flow, so that the air outside the cabinet 1 enters the cabinet 1, and the air inside the cabinet 1 is discharged from the cabinet 1, so that the relatively dry air outside enters the cabinet 1 and the relatively humid air inside the cabinet 1 is discharged to the outside of the cabinet 1, thereby reducing the humidity inside the cabinet 1 and protecting the components inside the cabinet 1. When the first humidity sensor 21 detects that the humidity in the cabinet 1 drops below the set threshold, dehumidification is completed, and the controller 23 controls the fan 3 to turn off, and then the controller 23 controls the driving member 42 to move the driving member 42 from the open position to the closed position to close the air outlet.

[0039] Specifically, m=3, and there are three air outlets. Of the three fans 3 corresponding to the three air outlets, two fans 3 are fans 3 for taking air into the cabinet 1, and one fan 3 is a fan 3 for exhausting air out of the cabinet 1, that is, two air outlets are air inlets and one is an air outlet.

[0040] In some embodiments, the moisture-proof electrical cabinet 100 further includes a mounting frame 5, which is disposed at the air outlet and protrudes from the outer surface of the cabinet 1. A baffle 41 is movably disposed on the mounting frame 5, the baffle 41 being located outside the fan 3, and a drive member 42 is disposed on the mounting frame 5. The mounting frame 5 provides installation space for the sealing assembly 4, avoiding the need for directly opening holes in the cabinet 1, thereby improving the sealing performance of the baffle 41 on the air outlet.

[0041] In some embodiments, as Figure 4 and Figure 5 As shown, the driving member 42 includes a driving motor 421, a screw rod 422, a nut seat and a driving block 423. The driving motor 421 is provided on the outer side of the mounting frame 5. The screw rod 422 is rotatably provided on the outer side of the mounting frame 5. The screw rod 422 is drivingly connected to the output shaft of the driving motor 421. The nut seat (not shown in the figure) is mounted on the screw rod 422. One side of the driving block 423 is provided on the nut seat. The mounting frame 5 is provided with a first slide groove 51. The middle part of the driving block 423 is slidably provided in the first slide groove 51. The other side of the driving block 423 is connected to the baffle 41. The driving motor 421 drives the screw rod 422 to rotate, thereby driving the nut seat to move on the screw rod, thereby driving the driving block 423 to move in the first slide groove 51. The driving block 423 drives the baffle 41 to move synchronously, thereby realizing the movement of the baffle 41 between the closed position and the open position.

[0042] Specifically, as shown in the figure, the extension direction of the screw rod 422 is parallel to the wall of the cabinet 1 where the screw rod 422 is located, and the opening of the baffle 41 is also parallel to the wall of the cabinet 1. Then, in the open state, the baffle 41 is located on one side of the air outlet, and the baffle 41 does not form an obstruction on the air flow path. The airflow formed by the fan 3 in the open state will not affect the baffle 41, thereby ensuring the stability of the baffle 41 and preventing the baffle 41 from being offset and deviating from the original moving trajectory, thereby ensuring the stability and reliability of the baffle 41 during movement.

[0043] Furthermore, the mounting frame 5 is provided with a second slide groove, a mounting groove 52 and an avoidance hole. The second slide groove is opposite to the first slide groove 51. The baffle 41 is slidably arranged in the second slide groove. The mounting groove 52 and the avoidance hole are opposite. The first slide groove 51, the mounting groove 52, the second slide groove and the avoidance hole are connected in sequence. The sealing assembly 4 further includes a sealing ring 43, which is sleeved on the baffle 41. In this closed position, the four sides of the sealing ring 43 are respectively located in the first slide groove 51, the mounting groove 52, the second slide groove and the avoidance hole.

[0044] As the driver 42 drives the baffle 41 from the closed position to the open position, the baffle 41 moves from the avoidance hole toward the outside of the mounting frame 5, and the distance between the baffle 41 and the mounting slot 52 gradually increases. The first slide groove 51, the second slide groove, and the avoidance hole provide support and position limiting for the baffle 41 during its movement. As the driver 42 drives the baffle 41 from the open position to the closed position, the baffle 41 moves from the avoidance hole toward the inside of the mounting frame 5, and the distance between the baffle 41 and the mounting slot 52 gradually decreases. When the baffle 41 moves to the closed position, the four edges of the baffle 41 are respectively located within the first slide groove 51, the mounting slot 52, the second slide groove, and the avoidance hole. The sealing ring 43 mounted on the baffle 41 can fill the gap between the connection between the baffle 41 and the mounting frame 5 (that is, fill the gap between the baffle 41 and the first slide groove 51, the gap between the baffle 41 and the mounting groove 52, the gap between the baffle 41 and the second slide groove, and the gap between the baffle 41 and the avoidance hole), thereby increasing the sealing between the baffle 41 and the mounting frame 5, preventing air circulation inside and outside the cabinet 1 in the closed position, and preventing moisture in the external environment from entering the cabinet 1.

[0045] In some embodiments, the moisture-proof electrical cabinet 100 further includes a filter 6, which is provided at the air outlet. The filter 6 can filter the air flowing through the air outlet to prevent impurities in the external environment from entering the cabinet 1 when the air is taken in.

[0046] In some embodiments, as Figures 6 to 8 As shown, the moisture-proof electrical cabinet 100 further includes a moisture-absorbing assembly 7, which includes a fixing bar 71, a placement plate 72, and a moisture-absorbing bag 73. The fixing bars 71 are provided on opposite sides of the cabinet 1, protruding from the inner wall of the cabinet 1. The placement plates 72 are provided on the two fixing bars 71, and the moisture-absorbing bag 73 is placed on the placement plates 72. The moisture-absorbing bag 73 absorbs excess moisture to maintain a dry environment within the cabinet 1, helping to extend the service life of electrical components and reduce the risk of electrical failures caused by moisture.

[0047] Specifically, the moisture absorbing bag 73 is a carbon bag.

[0048] Further, such as Figure 7 and Figure 8 As shown, one of the fixing bar 71 and the placement plate 72 is provided with a limiting groove 711, and the other of the fixing bar 71 and the placement plate 72 is provided with a clamping block 721, which is disposed in the limiting groove 711. The placement plate 72 and the fixing bar 71 are connected by the cooperation of the clamping block 721 and the limiting groove 711, which facilitates the placement and removal of the placement plate 72 in the cabinet 1. At the same time, the cooperation of the clamping block 721 and the limiting groove 711 can also improve the firmness of the connection between the placement plate 72 and the cabinet 1.

[0049] The placement plate 72 is provided with a plurality of communicating holes, so that the air above and below the placement plate 72 are connected, thereby evenly absorbing moisture from the cabinet 1 and avoiding high humidity in some areas of the cabinet 1 .

[0050] like Figure 9 As shown, the moisture-proof electrical cabinet 100 of the embodiment of the present invention further includes a wiring harness assembly 8, which includes a fixing block 81, a wiring harness block 82, a connecting piece 83 and a first elastic member 84. The fixing block 81 is provided on the inner wall surface of the cabinet body 1, and a wiring harness groove 811 and a plurality of limiting holes 812 are provided on the fixing block 81. One side of the wiring harness groove 811 is open, and the wiring harness groove 811 is connected to the limiting holes 812. The wiring harness block 82 is movably installed in the limiting holes 812. The connecting piece 83 is provided at one end of the wiring harness block 82. The first elastic member 84 connects the fixing block 81 and the connecting piece 83 to form a force on the wiring harness block 82 toward the wiring harness block 82. The other end of the wiring harness block 82 is provided with a first limiting column 822 and a second limiting column 823. The first limiting column 822 and the second limiting column 823 are spaced apart. The first limiting column 822, the second limiting column 823 and the inner wall surface of the wiring harness groove 811 define a wiring harness space.

[0051] When wiring is needed due to replacing components, etc., the connecting piece 83 is pulled away from the fixed block 81, so that the wiring block 82 moves away from the fixed block 81, and the first limiting column and the second limiting column move into the limiting hole 812. At this time, the wires can be moved from the open side of the wiring trough 811 into the wiring trough 811, and at the same time the first elastic member 84 is stretched, and the wires are aligned with the pulled wiring block 82, and then the connecting piece 83 is released. Under the action of the elastic force of the first elastic member 84, the wiring block 82 moves toward the wiring trough 811, and relies on the elastic force of the first elastic member 84 to fix the wiring block 82, so that the wires are confined between the first limiting column and the second limiting column.

[0052] Specifically, a pull ring 831 is rotatably provided on the connecting piece 83 . The pull ring 831 is convenient for personnel to apply force. Personnel can drive the connecting piece 83 and the cable bundle block 82 by holding the pull ring 831 .

[0053] Specifically, the first elastic member 84 is a first spring, and the first spring is sleeved on the wiring harness block 82 .

[0054] Furthermore, the other end of the harness block 82 is provided with a receiving groove 821, which is located between the first limiting post 822 and the second limiting post 823. The harness assembly 8 further includes a second elastic member 85 and a clamping block 86. The second elastic member 85 is disposed in the receiving groove 821 and connects the harness block 82 and the clamping block 86. The second elastic member 85 forms a force on the clamping block 86 toward the harness space. When the wires are confined in the harness space, under the action of the second elastic member 85, the clamping block 86 abuts against the wires, so that the wires are located between the wall of the harness groove 811 and the clamping block 86, further fixing and constraining the wires.

[0055] Specifically, the cabinet 1 comprises a main body 11 and a door 12. The main body 11 is provided with the air vent, and the door 12 is hinged to the main body 11. The door 12 is provided with an observation window 13 and a handle 14, through which staff can observe the operating status of the components within the cabinet 1. The door 12 is also equipped with a mounting lock, which secures the door 12 to the main body 11, and a warning sign, which reminds staff to pay attention to operating procedures.

[0056] Therefore, in the moisture-proof electrical cabinet 100 of the embodiment of the present invention, when the humidity in the cabinet 1 exceeds the preset threshold and the external air humidity is lower than the air humidity in the cabinet 1, the baffle 41 automatically moves to the open position and the fan 3 is turned on. By allowing drier airflow to enter the cabinet 1 and removing the moister airflow from the cabinet 1, the air flow in the cabinet 1 is realized, and the moisture accumulated in the cabinet 1 is quickly removed from the cabinet 1, maintaining a dry environment in the cabinet 1, avoiding problems such as rust of components and reduction of insulation due to moisture, and providing continuous and reliable operation guarantee for various components in the electrical cabinet 100.
