[0032] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0033] Embodiment 1:

[0034] like Figure 1-3 As shown, an electrical control cabinet comprises a cabinet body 1 and a cabinet door 2 connected to one side of the cabinet body 1 through a hinge.

[0035] The cabinet 1 is divided into a cavity 1 3 and a cavity 2 6 by a partition 4, and the inner wall of the partition 4 is provided with a plurality of connecting grooves, and grooves 5 are provided on both sides of the cabinet 1, and a plurality of vents are provided between the grooves 5 and the cavity 2 6, and a baffle 17 is rotatably connected to the vent through a rotating shaft 18, and a plurality of baffles 17 are coupled through a linkage assembly. A dehumidification assembly 8 for dehumidifying the cabinet 1 is provided in the cavity 2 6, and the cabinet 1 is made of an anti-corrosion material and is coated with an anti-corrosion coating on the surface. In this embodiment, no specific structural limitation is made to the anti-corrosion material and the anti-corrosion coating, wherein the anti-corrosion material may be stainless steel, aluminum alloy, etc., and the anti-corrosion coating may be a polyurethane anti-corrosion coating, an epoxy coating, etc.

[0036] Since the device is located in a sewage treatment plant, the environment is relatively humid. After all the baffles 17 are rotated open, the dehumidification component 8 can be used to accelerate the air flow in the chamber 1 3 and the chamber 2 6, thereby achieving a dehumidification effect. However, some acid and alkaline gases will be generated during sewage treatment, which will corrode the cabinet 1 and internal electrical components. Therefore, when acid and alkaline gases are generated, all the baffles 17 are rotated closed to prevent the gas from entering the cabinet 1. After the gas is dispersed or processed, the baffles 17 are opened again to ensure ventilation of the cabinet 1.

[0037] The device is provided with a plurality of baffles 17. When the baffles 17 are rotated to open, the dehumidification component 8 can accelerate the flow of gas in the cabinet 1 to achieve the effect of dehumidification and heat dissipation. When the baffles 17 are rotated to close, external acid and alkali gases can be prevented from entering the cabinet 1 to cause corrosion damage to the internal electrical components, thereby ensuring the normal operation of the device and extending its service life.

[0038] like Figure 2 and Figure 3 As shown, a controller 10 is installed in the cavity 1 3 , a pH meter 9 is installed on the top of the groove 5 , and the pH meter 9 is electrically connected to the controller 10 .

[0039] The linkage assembly includes an electric push rod 11, a connecting rod 12, a connecting rod 2 14 and a plurality of connecting rods 3 15 and 4 16. The connecting rod 2 14 is rotatably connected to the topmost rotating shaft 18, and the connecting rod 3 15 is rotatably connected to the outer walls of the remaining rotating shafts 18.

[0040] The connecting rod 2 14 and one of the connecting rods 3 15 as well as two adjacent connecting rods 3 15 are rotatably connected to the same connecting rod 4 16 .

[0041] One end of the connecting rod 12 is rotatably connected to the connecting rod 2 14, and the other end of the connecting rod 12 is rotatably connected to the slider 13, the slider 13 slides in the inner wall of the cavity 2 6, the electric push rod 11 is fixed to the bottom of the partition 4 by bolts, the telescopic end of the electric push rod 11 is fixedly connected to the top of the slider 13, and the electric push rod 11 is electrically connected to the controller 10.

[0042] When the pH meter 9 detects that the current pH value in the air exceeds the standard, the signal is transmitted to the controller 10, and the controller 10 starts the electric push rod 11 to drive the slider 13 to slide upward, thereby utilizing the cooperation between the connecting rod 2 14, the connecting rod 3 15 and the connecting rod 4 16 to drive multiple baffles 17 to rotate and close at the same time. When the gas is dispersed or processed, the pH meter 9 transmits a signal to the controller 10, and the controller 10 starts the electric push rod 11 again to drive the slider 13 to slide downward, thereby driving the multiple baffles 17 to rotate and open, thereby ensuring ventilation inside the cabinet 1.

[0043] The device is provided with a linkage assembly. When the electric push rod 11 drives the slider 13 to rise or fall, the cooperation of the connecting rod 12, the connecting rod 2, the connecting rod 3, the connecting rod 15 and the connecting rod 4, the connecting rod 16 can simultaneously drive multiple baffles 17 to rotate, close or open, thereby improving the operating efficiency.

[0044] In this embodiment: when in use, the baffle 17 remains in a normally open state, and cooperates with the dehumidification component 8 to accelerate the air flow in the cabinet 1 to prevent humid gas from being retained in the cabinet 1. When the pH meter 9 detects that the current air pH value exceeds the standard, it means that the current air contains acid-base gases. The pH meter 9 transmits a signal to the controller 10, and the controller 10 starts the electric push rod 11. The electric push rod 11 drives the slider 13 to slide upward, and with the cooperation of the connecting rod 2 14, the connecting rod 3 15 and the connecting rod 4 16, all the baffles 17 are driven to close at the same time, thereby preventing acid-base gases from entering the cabinet 1 and causing corrosion damage to the internal electrical components.

[0045] Embodiment 2:

[0046] An electrical control cabinet, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 2 and Figure 4 As shown:

[0047] The dehumidification assembly 8 includes a fixing frame 19 and a fan blade 20. The fan blade 20 is rotatably connected to the inner wall of the fixing frame 19 via a transmission shaft. A motor 21 is fixed to the outer wall of one side of the fixing frame 19 via bolts. The output shaft of the motor 21 is connected to the transmission shaft via a coupling.

[0048] The fixing frame 19 is fixed to the inner wall of the second chamber 6, and a hollow box 7 is fixed to the outer wall of the fixing frame 19 away from the motor 21 by bolts, and a drying bag is placed in the hollow box 7. The drying bag can be activated carbon, calcium chloride, etc., and is placed in a woven bag that allows gas to pass.

[0049] In this embodiment: the starting motor 21 drives the transmission shaft and the fan blades 20 to rotate, thereby accelerating the air flow. When the air passes through the hollow box 7, the air is dried by the drying bag. When the drying bag needs to be replaced, the hollow box 7 is removed from the fixing frame 19 by rotating the bolts, and then a new drying bag is placed in the hollow box 7. Finally, the hollow box 7 and the fixing frame 19 are fixed again by bolts.

[0050] The device accelerates the air flow in the cabinet 1 by setting the fan blades 20, starting the motor 21 to drive the transmission shaft to drive the fan blades 20 to rotate, and uses the drying bag in the hollow box 7 to dry the air, thereby achieving the purpose of dehumidification, avoiding excessive humidity in the cabinet 1 that causes the insulation strength of the device to decrease, causing leakage, short circuit and other faults, and improving the installability and stability of the device.

[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
