Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] The present invention provides the following specific implementation scheme:

[0024] like Figures 1-4 As shown, this utility model provides an intelligent dehumidification device for power distribution cabinets, including a housing, a humidity sensor 19, and a controller 6. An air outlet 3 is opened on the front side of the housing. An axial flow fan 12 for air extraction and a refrigeration component for condensing water vapor are arranged sequentially on the rear side of the air outlet 3. An air inlet channel 7 is provided on the upper side of the refrigeration component. An air inlet 5 connected to the air inlet channel 7 is opened on the housing. A water storage tank 13 is provided on the lower side of the refrigeration component. A buzzer 20 is also installed on the upper side of the housing. A buzzer switch 17 and multiple elastic support components 16 are provided between the water storage tank 13 and the inner wall of the bottom of the housing. During the operation of the refrigeration component, condensed water flows into the water storage tank 13. As the water in the water storage tank 13 increases, the water storage tank 13 squeezes the elastic support components 16. When the water in the water storage tank 13 reaches a set amount, the bottom of the water storage tank 13 touches the buzzer switch 17.

[0025] Furthermore, in order to allow staff some reaction time, when the water in the water tank 13 reaches three-quarters of its volume, the bottom of the water tank 13 touches the buzzer switch 17. In addition, in some high humidity areas, the set amount can be adjusted to be smaller as needed. The adjustment of the set amount can be achieved by using springs with different elastic coefficients.

[0026] Furthermore, the cooling component is a semiconductor cooling system, which includes a cooling plate 9, a cooling chip 11, a mixing channel, and a heat sink 10. The cooling plate 9 is arranged behind the cooling chip 11, and the heat sink 10 is arranged in front of the cooling chip 11. The air inlet channel 7 is located above the cooling plate 9, and the water storage tank 13 is located below the cooling plate 9. A heat insulation layer is also provided between the cooling plate 9 and the heat sink 10. The mixing channel passes through the cooling plate 9, the heat insulation layer, and the heat sink 10. In this embodiment, the mixing channel is a through hole of the cooling plate 9, the heat insulation layer, and the heat sink 10.

[0027] Furthermore, there are four elastic support components 16, which are respectively arranged at the four corners of the lower surface of the water storage tank 13. The elastic support component 16 includes a first guide rod 16.2 and a first spring 16.1 disposed around the first guide rod 16.2. The first guide rod 16.2 includes a hollow part fixedly connected to the housing and a solid part fixedly connected to the water storage tank 13. The solid part can slide up and down relative to the hollow part.

[0028] Furthermore, it also includes a battery 22 that powers the humidity sensor 19, controller 6, buzzer 20, cooling assembly, and axial fan 12. The controller 6 has a built-in control system that controls the operation of the axial fan 12 and cooling assembly based on the signal from the humidity sensor.

[0029] Furthermore, a drain pipe 14 is provided at the lower center of the water storage tank 13. The drain pipe 14 includes a rigid pipe 14.1 and a corrugated pipe 14.2. The rigid pipe 14.1 is fixedly connected to the housing, and the lower end of the corrugated pipe 14.2 is fixedly connected to the rigid pipe 14.1. A corrugated pipe support assembly 18 is provided between the upper end of the corrugated pipe 14.2 and the inner wall of the bottom of the housing. The corrugated pipe support assembly 18 includes a hollow rod and a solid rod inserted into the hollow rod. A second spring is also provided inside the hollow rod. The second spring is located below the solid rod. Under the action of the second spring, the upper end of the corrugated pipe 14.2 abuts against the water storage tank 13. At this time, the elastic support assembly 16 and the corrugated pipe support assembly 18 jointly support the water storage tank 13. When adjusting the set amount of water in the water storage tank 13 required to trigger the buzzer 20, the corrugated pipe support assembly 18 must be taken into account.

[0030] Furthermore, an inspection port is provided on one side of the housing of the water storage tank 13, and a baffle 4 is installed on the inspection port. The baffle 4 is connected to the housing by a snap fastener.

[0031] Preferably, the rear side of the housing is provided with a mounting slot 8 to facilitate the installation of this device in the power distribution cabinet.

[0032] In this embodiment, when there is no water in the water storage tank 13, there is a gap between the water storage tank 13 and the cooling plate 9, which facilitates the later removal of the water storage tank 13 connected to the solid part of the first guide rod 16.2; the shell is composed of a front cover 1, a rear shell 15, and a bottom plate 21; the rear shell 15 is provided with an air inlet 5 on each of its left and right sides and the top side, and the air inlet 5 is equipped with a filter plate to filter large dust particles. The baffle 4 is rotatably connected to the rear shell 15 through a rotating shaft. The controller 6, the battery 22, and the axial flow fan 12 are all installed on the front cover 1 with screws. The front cover 1 is also provided with a display screen 2. The bottom plate 21 is fixedly connected to the hollow part of the first guide rod 16.2, and the baffle 4 is connected to the bottom plate 21 by a snap fastener.

[0033] In use, the device is installed in the distribution cabinet via the mounting slot 8. The humidity sensor 19 detects the air humidity inside the distribution cabinet and transmits the signal to the controller 6. When the controller 6 determines that the air humidity needs to be controlled, it sends a working signal to the axial flow fan 12 and the cooling plate 11. The axial flow fan 12 draws air in from the air inlet 5. When the air passes through the exhaust plate 9, the water vapor inside condenses and then the air is discharged from the air outlet 3. The condensate flows into the water storage tank 13 and is discharged through the drain pipe 14. When the controller 6 determines that the air humidity no longer needs to be controlled, it sends a stop working signal to the axial flow fan 12 and the cooling plate 11. When the drain pipe 14 is blocked due to the combination of dust and water, the water in the water storage tank 13 increases, thus pressing down the elastic support device. When the water reaches three-quarters of the volume of the water storage tank 13, the bottom of the water storage tank 13 touches the buzzer 20 switch, and the buzzer 20 is energized and operates.

[0034] This invention provides an elastic support and a buzzer 20 switch on the lower side of the water storage tank 13, so that when the water storage tank 13 reaches a certain level, the buzzer 20 can be triggered to alert the staff of the risk and avoid safety accidents.

[0035] An inspection port for cleaning the water storage tank 13 is added to the side of the housing, which makes it more convenient to clean the water storage tank 13 without disassembling the entire device.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
