Description

Technical Field

[0001] The utility model relates to an electric control cabinet, belonging to the technical field of electric control cabinets. Background Technique

[0002] An electric control cabinet is an indispensable device in modern industrial automation, mainly used for controlling, protecting and monitoring electrical systems. It mainly consists of control components, protection devices, main circuit components and busbars, etc. Through these components, functions such as control, protection, monitoring and measurement of electrical equipment are realized to ensure the safe, stable and efficient operation of electrical equipment or systems.

[0003] The authorized announcement number (CN 219959791 U) is an electric power distribution cabinet, including a cabinet body and an installation frame. On both sides of the inner wall of the cabinet body, extension plates are respectively fixedly installed. A chute is opened at the top of the extension plate, and a connecting rod is slidably connected inside the chute. A fixing plate is fixedly clamped on the surface of the connecting rod. For this electric power distribution cabinet, during the insertion process, the top of the inserted limiting rod fits against the bottom of the mounting substrate of the wiring board group to form a limit, avoiding automatic flipping under the action of gravity. By removing the inserted limiting rod, the wiring board group can rotate inside the connecting groove opened in the installation frame through the rotating shafts fixedly installed on both sides of the mounting substrate of the wiring board group, which is convenient for installing the wiring board group. During the whole operation process, the internal space utilization rate is maximized by changing the vertical installation method, and the flipping method is also convenient for installing the wiring board group, with stronger practicability;

[0004] However, during long-term use of the above technology, the electrical components inside the box will continuously generate heat, and the heat inside the box cannot be quickly discharged. If the heat inside the box cannot be discharged for a long time and remains in a high-temperature state, the service life of the internal electrical components will be greatly reduced, and it will be difficult to replace or repair them, which is not convenient for the staff to operate.

[0005] Therefore, an electric control cabinet is proposed. Content of the Utility Model

[0027] The following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0028] Embodiment 1

[0029] AsFigures 1-5 As shown in the figure, an embodiment of the utility model provides an electrical control cabinet, which includes a box body 1, a movable door 2 and a placement rack 3. The front side of the box body 1 is movably connected to the rear side of the movable door 2 through a hinge. A placement rack 3 is fixedly connected inside the box body 1. Rotating blocks 4 are movably connected to the left and right sides of the front side of the placement rack 3 through rotating shafts. A cavity 5 is provided inside the rotating block 4, and a positioning mechanism 6 is provided inside the cavity 5;

[0030] A heat dissipation mechanism 7 is arranged inside the box body 1. The heat dissipation mechanism 7 includes an exhaust fan 701 and a connecting pipe 703. The top of the exhaust fan 701 is fixedly connected to the top of the inner wall of the box body 1. An air suction port 702 is fixedly communicated with the top of the exhaust fan 701. Connecting pipes 703 are fixedly communicated with the left and right sides of the exhaust fan 701 respectively. The opposite sides of the two connecting pipes 703 penetrate through the left and right sides of the box body 1 respectively. The placement rack 3 is divided into two layers. A number of heat dissipation holes 8 are opened at the bottom of the placement rack 3. Through holes 9 are opened on both the left and right sides of the box body 1 and the number of the through holes 9 is several.

[0031] Through the heat dissipation mechanism 7, by starting the exhaust fan 701, the heat inside the box body 1 is discharged through the air suction port 702 and through the connecting pipe 703. When the electrical cabinet is in use, the heat inside the box body 1 can be fully reduced, and the service life of the internal electrical components can be prolonged. By providing the heat dissipation holes 8, the air flow rate inside the box body 1 can be accelerated during use, ensuring a good heat dissipation effect.

[0032] Embodiment 2

[0033] In one embodiment, the positioning mechanism 6 includes a moving rod 601, a positioning rod 602 and a tension spring 603. The front side of the right moving rod 601 penetrates to the front side of the cavity 5. The rear side of the moving rod 601 penetrates to the front side of the positioning rod 602. The rear side of the positioning rod 602 is fixedly connected to the front side of the tension spring 603. The rear side of the tension spring 603 is fixedly connected to the inner wall of the cavity 5. The tension spring 603 is sleeved on the surface of the positioning rod 602. The rear side of the positioning rod 602 penetrates to the inside of the placement rack 3. A protective plate 10 is provided inside the box body 1. Fixing grooves 11 are opened on both the protective plate 10 and the front side of the placement rack 3. When the positioning rod 602 is inserted into the fixing groove 11, they are in close contact. A handle 12 is fixedly connected to the front side of the protective plate 10. A blocking block 13 is fixedly connected to the bottom of the placement rack 3. The front side of the blocking block 13 contacts the rear side of the protective plate 10.

[0034] Through the positioning mechanism 6, by rotating the rotating block 4, when the exhaust fan 701 is being overhauled and maintained, it can be quickly adjusted, facilitating the disassembly operation of the protective plate 10 by the staff. By providing the blocking block 13, it is convenient for operation and use when the protective plate 10 is being installed, and it can prevent the protective plate 10 from loosening during installation.

[0035] When the present utility model is working: when the temperature inside the box body 1 is too high and cannot dissipate heat by itself, the exhaust fan 701 is started. The air flow enters the inside of the box body 1 through the through hole 9, passes through the heat dissipation holes 8 and the air suction port 702 and then enters the inside of the exhaust fan 701 and is discharged from the two side connecting pipes 703, so as to achieve the effect of dissipating heat inside it by accelerating the flow rate of the cavity 5 inside the box body 1. When the exhaust fan 701 needs to be overhauled, the moving rod 601 is pulled forward. The moving rod 601 drives the positioning rod 602 to move forward. While the positioning rod 602 moves forward, the tension spring 603 is stretched, so that the positioning rod 602 moves into the cavity 5. The same operation is performed on the other side. At the same time, the rotating block 4 is rotated to the opposite side to make it in a horizontal state. The moving rod 601 is released. Through the pulling force of the tension spring 603, the positioning rod 602 is inserted into the fixing groove 11 again. At this time, the protective plate 10 can be pulled forward by holding the handle 12 to overhaul and maintain the exhaust fan 701. After the overhaul is completed, the protective plate 10 is put back. The moving rod 601 is pulled, and the rotating block 4 is rotated to make it in a vertical state. The moving rod 601 is released to stably fix the protective plate 10.

[0036] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
