Description

Technical Field

[0001] The present invention relates to the technical field of electric control cabinets, and in particular to an intelligent low-voltage electric control cabinet. Background Art

[0002] Low-voltage electrical control cabinets are usually used to store and protect electrical equipment, including inverters, contactors, relays, circuit breakers and other electrical components. Since these devices require power supply and electrical signal control, they involve electrical connections and junction boxes during use, and these need to be connected to the outside world.

[0003] If the electric control cabinet is not treated with moisture-proof during use, short circuit, fire and other safety problems are likely to occur. However, the existing electric control cabinet cannot be completely sealed because the heat dissipation of electrical components needs to be considered. Moreover, if it is in a special environment (such as coastal and water conservancy projects), the electric control cabinet will be in a humid and rainy environment. Therefore, the dehumidification of these electric control cabinets needs to be strengthened compared with the electric control cabinets in ordinary dry use environment. Summary of the invention

[0004] To this end, the present invention aims to provide an intelligent low-voltage electric control cabinet, which is provided with an induction dehumidification device, which can improve the dehumidification effect through the heat energy generated by electrical components, thereby improving the safety of the electric control cabinet.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An intelligent low-voltage electric control cabinet comprises an electric control cabinet body, electrical components are arranged inside the electric control cabinet body, an inductive dehumidification device is arranged inside the electric control cabinet body, the inductive dehumidification device comprises a dehumidification fan installed on the upper part of the electric control cabinet body and an inductive exhaust component installed on the lower part of the electric control cabinet body, the inductive exhaust component comprises a concave-shaped cabinet body, a water collecting trough is provided in the middle of the cabinet body, a humidity sensor is arranged in the water collecting trough, the inner edges on both sides of the cabinet body are inclined surfaces, and the top of the inclined surface is embedded in the inner side wall of the electric control cabinet body, a plurality of dehumidification channels are provided on the inclined surface, and a ventilation groove connected to the dehumidification channel is provided on the side wall of the electric control cabinet body.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] In the present invention, an induction dehumidification device is provided. When the humidity sensor in the water collection tank detects that the humidity in the air is greater than the set humidity, the controller will control the dehumidification fan to start, and the dehumidification fan will blow air downward. At this time, the heat energy generated by the electrical components when working turns the wind into hot air, and the hot air accelerates the evaporation of moisture in the electric control cabinet body, and a part of the moisture is discharged through the dehumidification channel and the ventilation groove, thereby reducing the air humidity inside the electric control cabinet body and improving safety.

[0009] As an improvement, limiting grooves for the cabinet to be embedded are provided on the two inner walls of the electric control cabinet body. This makes it easier for the cabinet to be installed inside the electric control cabinet body. Moreover, the inclined surfaces on both sides of the cabinet body can be embedded in the limiting grooves, so that water vapor on the electric control cabinet body can condense and flow downward, and finally flow into the water collection tank.

[0010] As an improvement, the dehumidification fan includes a shell, blades, a double-headed motor and a swinging mechanism for fixing the shell to the upper part of the electric control cabinet body. The shell is composed of a panel and a turbine shell. The double-headed motor is fixed to the middle of the turbine shell. Blades are respectively fixed on the two output shafts of the double-headed motor. An air inlet is provided on the back of the turbine shell, and an air outlet is provided on the panel. In this way, the structure is simple and can be driven by a double-headed motor to make the length of the dehumidification fan longer, thereby effectively ensuring the air outlet area of ​​the dehumidification fan.

[0011] As an improvement, the swing mechanism includes a fixed sleeve, a U-shaped mounting seat, a driving motor, a first transmission gear, a second transmission gear and a transmission chain. The fixed sleeve is fixed to the upper end of the side wall of the electric control cabinet body, one end of the U-shaped mounting seat is inserted into the fixed sleeve, and the other end is fixedly connected to the shell. A connecting rod is arranged on the outside of the end of the U-shaped mounting seat inserted into the fixed sleeve, and the first transmission gear is fixed on the connecting rod. The driving motor is mounted on the side wall of the electric control cabinet body, and a second transmission gear is fixed on the output shaft of the driving motor. The first transmission gear and the second transmission gear are connected by a transmission chain. In this way, the dehumidification fan can swing through the setting of the swing mechanism, thereby increasing the area where the hot air inside the electric control cabinet body is blown, thereby improving the dehumidification effect. Moreover, such an installation structure is easy to install.

[0012] As an improvement, the connecting rod and the end of the U-shaped mounting seat inserted into the interior of the fixed sleeve are arranged on the same central axis, thus ensuring that the U-shaped mounting seat can rotate.

[0013] As an improvement, the fixing sleeve is welded on the fixing plate, and the fixing plate is connected to the electric control cabinet body by screws, so that the installation structure is simpler.

[0014] As an improvement, a bearing is fixed inside the fixed sleeve, and the U-shaped mounting seat is connected to the fixed sleeve via the bearing. In this way, the setting of the bearing enables one end of the U-shaped mounting seat to rotate, and can also play an axial fixing role on the U-shaped mounting seat, thereby assembling the fixed sleeve and the U-shaped mounting seat.

[0015] As an improvement, the dehumidification channels are arranged in parallel up and down, and the diameter of the dehumidification channels gradually decreases from the inside to the outside. This is conducive to the discharge of internal air, and the small diameter of the external channel can prevent air from flowing in.

[0016] As an improvement, a float level switch is also provided at the bottom of the sump, and a wireless alarm device and a controller are also provided inside the electric control cabinet body. The float level switch, humidity sensor, and wireless alarm device are all electrically connected to the controller. In this way, the design of the float level switch can further ensure the safety of the electric control cabinet to prevent excessive humidity or floods, water backflow into the electric control cabinet, thereby submerging electrical components and causing a short circuit. When the water at the bottom of the sump accumulates to a certain height, the float level switch is triggered, and the value of the humidity sensor also reaches 100%, the controller will control the wireless alarm device to send the alarm information to the relevant personnel for reminders, which is more intelligent and safer.

[0017] As an improvement, a mounting structure for mounting a float level switch is provided at the bottom of the water collection tank, the mounting structure comprising a mounting groove opened on the bottom wall of the water collection tank, a first U-shaped connector and a second U-shaped connector, the first U-shaped connector being installed in the mounting groove, a spherical clamping piece being provided in the middle of the first U-shaped connector, positioning grooves being provided on the two side walls of the first U-shaped connector, the top of the second U-shaped connector being connected to the bottom of the float level switch, positioning protrusions which can be inserted into the positioning grooves are provided on both sides of the lower end of the second U-shaped connector, the lower end of the second U-shaped connector can be inserted into the first U-shaped connector, and the spherical clamping piece can prop open the two wings of the second U-shaped connector.
