Description

Technical Field

[0001] This utility model relates to the field of switch cabinets, and more specifically, to a switch cabinet with automatic moisture removal capability. Background Technology

[0002] Switchgear is a device in a power system used to control, protect, and distribute electrical energy. It typically includes components such as circuit breakers, contactors, relays, protective devices, and energy metering devices, used to control the start and stop of electrical equipment, regulate current and voltage, and protect the safe operation of electrical equipment and lines.

[0003] Switchgear is often installed in humid environments, such as basements and water rooms. Long-term exposure to humid environments can easily cause moisture to enter the switchgear, resulting in the electrical equipment inside the switchgear becoming damp and ultimately causing damage to the switchgear.

[0004] Currently, exhaust fans are commonly used to quickly remove moisture from switch cabinets. However, since exhaust fans need to be connected to the outside, they can generally only be fixed on the switch cabinet, and the area they can cover is small, resulting in poor dehumidification. If you want to move the exhaust fan for large-scale dehumidification, you need to make a larger opening in the cabinet to allow the drive unit to move the exhaust fan. However, a larger opening increases the risk of external objects (birds, flying insects, etc.) entering.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a switch cabinet with automatic moisture removal capability. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a switch cabinet with automatic moisture removal.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatically dehumidifying switch cabinet, comprising a switch cabinet body equipped with internal electrical equipment, wherein circular through slots are provided on both the top and bottom sides of one side of the switch cabinet body, and the automatically dehumidifying switch cabinet further includes:

[0008] Two dehumidification components are installed on the switch cabinet body, flush with the circular through groove. Each dehumidification component includes a circular plate connected to the switch cabinet body via a connecting plate A. The circular plate is located within the circular through groove and the two have the same center. A motor is installed on the circular plate. The drive shaft of the motor is connected to a ring plate via a connecting plate B. The ring plate covers the gap formed between the circular through groove and the circular plate. An exhaust fan is embedded and fixed inside the ring plate, penetrating the inner and outer surfaces of the ring plate.

[0009] An automatic dehumidification controller is installed at one end of the switch cabinet opposite the dehumidification component and is used to control the operation of the dehumidification component.

[0010] Preferably, ventilation holes are provided on the front and rear surfaces of the switch cabinet near the bottom, and the ventilation holes are provided with caps to prevent water droplets from entering from these locations.

[0011] Preferably, the bottom of the switch cabinet is provided with multiple ventilation slots arranged in an array, and the two sides of the switch cabinet are supported to a certain height by support components, and the bottom can also be ventilated, which is conducive to the rapid discharge of water vapor.

[0012] Preferably, the supporting component includes an L-shaped plate fixed on both sides of the switch cabinet near the bottom, and a cast iron counterweight base is fixedly connected to the bottom of the L-shaped plate to stably support the switch cabinet.

[0013] Preferably, a desiccant tank is detachably connected to the inner bottom wall of the switch cabinet at the location between the ventilation slots.

[0014] Preferably, the inner bottom wall of the switch cabinet is fixed to the groove seat by a vertical rod at the part between the ventilation slots. A circular through hole is opened on one side of the groove seat. A square shell is inserted into the groove seat. The side of the square shell opposite to the circular through hole is open. The inner surface of the square shell is fixed to the movable plate by a telescopic rod. A spring is also provided between the movable plate and the square shell. A cylindrical protrusion that can be inserted into the circular through hole is fixedly connected to the surface of the movable plate. The top of the square shell is fixed to the bottom of the desiccant tank to realize quick disassembly of the desiccant tank.

[0015] Preferably, the automatic dehumidification controller includes:

[0016] The humidity detection module consists of two humidity sensors, one on the top and one on the bottom of the switch cabinet. When the humidity sensor detects an abnormal humidity inside the switch cabinet, it sends a signal to the microprocessor control module.

[0017] The microprocessor control module sends signals to the execution drive module to control the operation of the motor and the exhaust fan or to stop their operation, based on the signals transmitted by the humidity detection module.

[0018] Drive module: Based on signals issued by the microprocessor control module, it drives the motor and the exhaust fan to run or both to shut down;

[0019] Power module: Used to supply power to the equipment on the automatic dehumidification controller.

[0020] The four modules work together to achieve intelligent driving of the dehumidification components, thereby enabling automatic dehumidification.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This utility model uses a motor to drive the rotation of a circular plate, which in turn drives the rotation of an exhaust fan. The exhaust fan rotates along the gap formed between the circular groove and the circular plate. Simultaneously, the circular plate covers the gap between the circular groove and the circular plate, allowing the exhaust fan to rotate in a circle, increasing its effective area and quickly removing moisture. Furthermore, the absence of large openings eliminates the risk of external objects entering, thus solving the problem in the prior art where moving an exhaust fan for large-scale dehumidification requires creating a large opening in the cabinet for the drive assembly to move the fan, which could lead to the entry of external objects.

[0023] 2. This utility model can automatically dehumidify the inside of the switch cabinet through an automatic dehumidification controller, without the need for manual intervention.

[0024] 3. This utility model, through its detachable structure, allows for quick assembly and disassembly of the dehumidifier canister, thereby better assisting in dehumidification. Attached Figure Description

[0032] like Figure 1-5 As shown, this utility model provides a switch cabinet with automatic dehumidification capability, including a switch cabinet body 1 equipped with electrical equipment inside. Circular through slots 2 are provided on both the top and bottom sides of one side of the switch cabinet body 1. The switch cabinet with automatic dehumidification capability also includes:

[0033] Two dehumidification components 3 are installed on the switch cabinet body 1 at the same level as the circular through groove 2. Each dehumidification component 3 includes a circular plate 302 connected to the switch cabinet body 1 via a connecting plate A301. The circular plate 302 is located inside the circular through groove 2 and the two have the same center. A motor 303 is installed on the circular plate 302. The drive shaft of the motor 303 is connected to a ring plate 305 via a connecting plate B304. The ring plate 305 covers the gap formed between the circular through groove 2 and the circular plate 302. An exhaust fan 306 is embedded and fixed inside the ring plate 305, penetrating the inner and outer surfaces of the ring plate 305.

[0034] Automatic dehumidification controller 4 is located at the end of the switch cabinet 1 opposite to the dehumidification component 3, and is used to control the operation of the dehumidification component 3.

[0035] When the automatic dehumidification controller 4 detects that the humidity inside the switch cabinet 1 is too high, it will control the operation of the dehumidification component 3, that is, drive the motor 303 and the exhaust fan 306 (the exhaust fan 306 is powered by a battery). The motor 303 drives the rotation of the annular plate 305, and the annular plate 305 drives the rotation of the exhaust fan 306, so that the exhaust fan 306 rotates along the gap formed between the annular groove and the circular plate 302. At the same time, the annular plate 305 covers the gap formed between the annular groove 2 and the circular plate 302, so that the exhaust fan 306 can rotate in a circle, increasing its effective area and quickly expelling moisture. At the same time, there is no large opening, so there is no risk of external objects entering.

[0036] The automatic dehumidification controller 4 includes a humidity detection module, which consists of two humidity sensors 401 located on the upper and lower sides of the switch cabinet 1. When the humidity sensor 401 detects an abnormal humidity inside the switch cabinet, it sends a signal to the microprocessor control module.

[0037] The microprocessor control module (microcontroller) sends signals to the execution drive module to control the operation of the motor 303 and the exhaust fan 306 or to stop their operation, based on the signals transmitted by the humidity detection module.

[0038] Drive module (actuator): Drives the operation of motor 303 and exhaust fan 306 or shuts them down based on signals issued by the microprocessor control module;

[0039] Power module: Used to power the equipment on the automatic dehumidification controller 4, or can be powered directly from the switch cabinet.

[0040] The humidity sensor 401 (model: HS1101) detects the moisture in the switch cabinet 1. When the humidity sensor 401 detects that the moisture is higher than the specified value, it sends a signal to the microprocessor control module. The microprocessor control module then sends a signal to the drive module to control the operation of the motor 303 and the exhaust fan 306. The drive module can then drive the motor 303 and the exhaust fan 306 to run, thereby quickly removing moisture.

[0041] Similarly, when the humidity sensor 401 detects that the humidity is below the specified value, it will also send a corresponding signal to the microprocessor control module. The microprocessor control module will then send a signal to the drive module to stop the motor 303 and the exhaust fan 306. Finally, the drive module will turn off the motor 303 and the exhaust fan 306, thus achieving the effect of automatic dehumidification.

[0042] Furthermore, ventilation holes 5 are provided on the front and rear surfaces of the switch cabinet 1 near the bottom, and each ventilation hole 5 is equipped with a cap 6. The air inlet of the ventilation hole 5 is guided directly downward through the cap 6 to prevent water droplets from entering. At the same time, multiple ventilation slots 19 arranged in an array are provided at the bottom of the switch cabinet 1. The two sides of the switch cabinet 1 are supported to a certain height by support components 7. In this way, the bottom of the switch cabinet 1 can also be ventilated by the ventilation slots 19 (the ventilation slots 19 are equipped with protective nets to prevent flying insects from entering). This can increase the ventilation of the switch cabinet 1, prevent moisture from staying in the switch cabinet 1 for a long time, and the switch cabinet 1 is supported to a certain height, which can effectively prevent the bottom of the switch cabinet 1 from getting damp.

[0043] The support component 7 includes L-shaped plates 8 fixed on both sides of the switch cabinet 1 near the bottom, and a cast iron counterweight base 9 is fixedly connected to the bottom of the L-shaped plate 8. The cast iron counterweight base 9 is relatively heavy and can stably support the switch cabinet 1.

[0044] A desiccant tank 10 is detachably connected to the inner bottom wall of the switch cabinet 1, located between the heat dissipation channels. The specific structure of the detachable tank is as follows: The inner bottom wall of the switch cabinet 1 is fixed to the recessed seat 12 by a vertical rod 11 at the location between the heat dissipation channels. A circular through hole 13 is provided on one side of the recessed seat 12. A square shell 14 is inserted into the recessed seat 12. The side of the square shell 14 opposite to the circular through hole 13 is open. The inner surface of the square shell 14 is fixed to the movable plate 16 by a telescopic rod 15. A spring 17 is also provided between the movable plate 16 and the square shell 14. A cylindrical protrusion 18 that can be inserted into the circular through hole 13 is fixedly connected to the surface of the movable plate 16. The top of the square shell 14 is fixed to the bottom of the desiccant tank 10.

[0045] The cylindrical protrusion 18 is pushed into the square shell 14. During this process, the cylindrical protrusion 18 drives the movable plate 16 to move, and the telescopic rod 15 retracts to maintain the linear movement of the movable plate 16. At the same time, the spring 17 is compressed. Then, the square shell 14 is inserted into the groove seat 12. After insertion, the cylindrical protrusion 18 is flush with the circular through hole 13. With the cylindrical protrusion 18 no longer obstructed, the spring 17 begins to extend in the opposite direction, thereby inserting the cylindrical protrusion 18 into the circular through hole 13. This completes the fixation between the square shell 14 and the groove seat 12, and also completes the installation of the dehumidifier can 10 (containing dehumidifier). Similarly, when the dehumidifier is used up, the cylindrical protrusion 18 is pressed into the square shell 14 through the circular through hole 13, and then the square shell 14 is pulled out from the groove seat 12 to disassemble the dehumidifier can 10. This is very convenient and quick.
