Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, and in particular to an electrical automation control cabinet that is easy to maintain. Background Technology

[0002] Electrical automation control cabinets are cabinets that integrate electrical components, automation equipment, and control systems. They are widely used in fields such as industrial automation and building automation to monitor, control, and protect electrical equipment.

[0003] Currently, existing control cabinets, in order to facilitate later inspection and maintenance, such as the electrical automation control cabinet disclosed in Chinese Patent No. CN222301179U, which is easy to inspect and maintain, have a sliding cabinet set inside the cabinet, so that the devices inside the cabinet can be easily slid outward, thereby facilitating maintenance personnel to inspect and maintain the devices.

[0004] Since electrical automation control cabinets are mostly located in the control room, where space is limited, the aforementioned existing technologies, although they can slide out electrical automation components through pull-out sliding cabinets to facilitate inspection and maintenance, require sufficient space between the two rows of control cabinets. This is necessary not only for staff to stand but also for the sliding cabinets to extend, making these existing technologies unsuitable for use in control rooms with limited space.

[0005] Therefore, this application provides an electrical automation control cabinet that is easy to maintain to meet the requirements. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an electrical automation control cabinet that is easy to maintain. In the prior art, although the electrical automation components can be slid out through the pull-out sliding cabinet to facilitate maintenance operations, this requires sufficient space between the two rows of control cabinets, not only for the staff to stand, but also for the sliding cabinet to slide out. This makes the prior art unsuitable for use in control rooms with limited space.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] An electrical automation control cabinet that is easy to maintain includes a base cabinet, a base fixed to the bottom of the base cabinet, an opening on one side of the base cabinet, a sliding cabinet with a horizontal sliding cover around the side of the base cabinet with the opening, and a cabinet door installed in the middle of the sliding cabinet.

[0009] The base cabinet has horizontal slide rails fixed symmetrically on both outer walls, and sliding strips are fixed symmetrically on both inner walls. The sliding strips are slidably installed in the slide rails, and fastening bolts are provided on the outer side of the sliding cabinet. The fastening bolts are threaded through the sliding strips and abut against the slide rails.

[0010] Optionally, the upper surface of the base cabinet is provided with a ventilation window, a filter screen is provided inside the ventilation window, and an installation groove is provided on the top inner wall of the sliding cabinet. A movable plate is flexibly installed in the installation groove, and a cleaning brush for abutting against the filter screen inside the ventilation window is installed on the lower surface of the movable plate.

[0011] Optionally, a plurality of springs are installed in the mounting slot, and the plurality of springs are connected to the movable plate to form an elastic installation.

[0012] Optionally, the sliding bar has a mounting hole, and the fastening bolt is threaded through the mounting hole to abut against the outer edge of the slide rail.

[0013] Optionally, a plurality of support legs are mounted on the lower end face of the base.

[0014] Optionally, the cabinet door is hinged to the central opening of the sliding cabinet, and an observation window is installed on the cabinet door.

[0015] Optionally, a mounting bracket is fixed inside the base cabinet, and an electrical automation control component is mounted on the mounting bracket.

[0016] Optionally, the vertical mounting surface of the mounting bracket is located within the side opening of the base cabinet.

[0017] Optionally, the electrical automation control components mounted on the mounting bracket include electrical components, automation equipment, power supply systems, terminal blocks, sensors and actuators, and communication modules.

[0018] Compared with the prior art, this utility model has at least the following beneficial effects:

[0019] In the above solution, by sliding the sliding cabinet on the outside of the base cabinet, when it is necessary to perform subsequent maintenance on the electrical automation control components installed on the mounting rack inside the base cabinet, the sliding cabinet can be pushed towards the base cabinet, thereby exposing the mounting rack from inside the base cabinet, providing a wider operating space for the staff. Compared with the pull-out structure in the existing technology, it occupies less space and is more suitable for use in control rooms with limited space.

[0020] In the above solution, by setting an air vent on the top of the base cabinet and a movable plate and cleaning brush on the top of the sliding cabinet, the cleaning brush can automatically clean the filter screen inside the air vent when the sliding cabinet slides towards the base cabinet, making it convenient to use.

[0021] In summary, this device not only provides workers with a wider maintenance and operation space, but also occupies a smaller volume, making it especially suitable for control rooms with limited space, and its overall performance is excellent. Attached Figure Description
