Description

A frequency converter cabinet with remote monitoring Technical Field

[0001] This utility model relates to the field of frequency converter cabinet technology, and more specifically, to a frequency converter cabinet with remote monitoring. Background Technology

[0002] Variable frequency drive (VFD) cabinets are control cabinets that utilize frequency converters to drive power units. Due to their excellent starting performance, speed regulation performance, and energy-saving effects, they have become the most widely adopted power drive method. As key equipment in industrial automation control systems, VFD cabinets are widely used in various motor drive scenarios, such as factory production lines, sewage treatment systems, and HVAC systems.

[0003] Traditional frequency converter cabinets can only be operated and monitored on-site. When the equipment is installed in remote areas or different areas of a large factory, maintenance personnel need to spend a lot of time and energy to go to the site to check the equipment's operating status and adjust parameters. This not only delays maintenance time but may also cause production interruption and result in huge economic losses. Therefore, a frequency converter cabinet with remote monitoring is proposed. Summary of the Invention

The controller, backup battery, and wireless transceiver are installed in the middle of the protective box, and the wireless transceiver transmits the information received by the controller to the central control console for convenient remote monitoring;

[0006] An adjustable support mechanism is provided in the middle of the cabinet. This mechanism facilitates the installation and support of internal equipment and allows for adjustment of the installation position as needed. Two fixed seats are fixedly connected to one side of the cabinet door. A threaded rod is provided in the middle of each fixed seat, and a motor is installed at one end of the threaded rod. A stabilizing slider is fitted in the middle of the threaded rod. A temperature measuring camera and a monitoring camera are fixedly connected to both sides of the stabilizing slider, respectively. Activating the motor controls the stabilizing slider to move the temperature measuring camera and the monitoring camera up and down, facilitating temperature and operational status monitoring of any component inside the cabinet and improving usability.

[0007] Preferably, the upper and lower side walls of the cabinet are provided with through holes for air intake and exhaust and dust filters. The exhaust fan, intake fan, motor, temperature measuring camera, and monitoring camera are all electrically connected to the controller and backup battery. The temperature measuring camera monitors the operating temperature of the components to avoid the situation where local high temperatures cannot be detected in time. The monitoring camera facilitates the monitoring of the operating status of the components. The controller facilitates the control and use, and can send the received monitoring information to the central control panel. The backup battery can still provide monitoring and heat dissipation for a certain period of time when the power is off.

[0008] Preferably, the adjustable support mechanism includes two first uprights fixed to the back of the cabinet cavity and two second uprights fixed to the side walls of the cabinet cavity, and the front side of the first uprights is provided with multiple mounting crossbars.

A stabilizing frame is fixedly connected to the bottom two sides of the support plate at positions corresponding to the second uprights, and an adjusting cross plate is inserted in the middle of the stabilizing frame.

[0011] Preferably, a pull plate and a second locking plate are fixedly connected to both ends of the adjusting crossbar, respectively. The second locking plate is adapted to the first upright and is located in the middle of the second locking hole. By adjusting the position of the first locking plate inserted into the first locking hole, the height of the mounting crossbar can be adjusted as needed. This facilitates the installation of devices on the surface of the mounting crossbar and adjusts the installation height of the devices according to the height of the mounting crossbar, making it convenient to use. By locking the second locking plate into the second locking hole, the height of the support plate can be limited. By adjusting the second locking plate to lock into the second locking hole at different heights as needed, the height of the support plate can be adjusted, facilitating the installation of devices on the top of the support plate and adjusting the installation height.
