[0001] The present invention relates to the technical field of electrical installation cabinets, and in particular to a multifunctional electrical installation cabinet based on module combination and an installation method thereof. Background Art

[0002] Electrical installation cabinets are cabinets used to protect the normal operation of electrical components. At present, most of the components in the electrical cabinets work non-stop, and the space of the electrical cabinets is small, so the temperature inside the electrical cabinets is high, which poses a great explosion safety hazard. In addition, the high temperature environment also accelerates the damage of electrical components.

[0003] At present, most electrical installation cabinets improve the heat dissipation effect by setting heat dissipation holes or fans in the cabinet body. However, the electrical components inside the cabinet are placed together, and most of the fans installed inside are fixed in a certain position and cannot be adjusted. Therefore, we propose a multifunctional electrical multifunctional electrical installation cabinet and its installation method. Summary of the Invention

Ventilation holes are provided on the other two opposite side walls of the cabinet body, and the cabinet door is provided on the other side wall opposite to the side wall where the motor is installed.

[0009] Description: By setting up storage modules that can be slidably assembled with the cabinet slide slots, multiple groups of storage modules can be assembled. At the same time, the heat dissipation module can dissipate heat for the electrical components in the cabinet. The electrical components can be cooled by cooperating with the first fan and the vents. The first fan can move left and right, up and down in the cabinet, and can perform targeted heat dissipation treatment on the electrical components to avoid damage to electrical components due to excessive heat and improve heat dissipation efficiency.

[0010] Furthermore, the upper part of the cabinet is a telescopic part and the lower part is a fixed part.

The tooth plate is rotatably connected to the second round rod and slidably connected to the flat plate.

[0018] Note: Through the above settings, the first fan can dissipate heat while the brush can move left and right and rotate at the same time to clean the dust on the electrical components on each storage module. The first fan and the second fan can blow the swept dust out of the vent.

[0019] Furthermore, a hole is provided on the side surface of the chassis located on the cabinet door side, and a foldable plate is provided on the side surface of the chassis to cooperate with the hole and be used to connect multiple groups of storage modules together.

[0020] Note: Multiple groups of storage modules are connected together through foldable plates, which can be used to connect any group of storage modules, thereby preventing the wiring from becoming loose when each group of storage modules is shaken individually.

[0021] Furthermore, the folding parts of the foldable panels are connected by hinges.

[0022] Description: The folding parts of the foldable board are connected by hinges, making the structure simple and reasonable.

[0023] Furthermore, sponge pads are provided at the openings, and a protective shell for the motor is provided on the outside of the cabinet.

[0024] Note: By setting the sponge pad, the connecting wires can be protected and fixed, and the motor protection shell can protect the motor.

[0025] The installation method of the electrical installation cabinet comprises the following steps:

[0026] S1: First, place the electrical components in the storage module, pull the pressure plate upward to extend the spring, and then place the electrical components on the chassis. The spring contracts and the pressure plate presses the electrical components tightly.

[0027] S2: Next, connect the connecting wires of the electrical components on the multiple storage modules through the cable management plate and the openings. Then, open the cabinet door, adjust the height of the cabinet to a suitable position, slide the chassis of the multiple storage modules into the slide slots, and place the multiple storage modules into the cabinet. When the chassis of the storage module located above slides into the slide slots, the first groove on the pressure plate slides into the cabinet along the protrusion on the slide plate. Then, close the cabinet door.

[0028] S3: Turn on the motor, the motor output shaft drives the connecting rod to rotate, and the connecting rod drives the first gear connected to it to move on the gear ring, thereby driving the first fan to move circumferentially in the cabinet. The first fan is turned on to rotate, and the first fan cooperates with the two vents to dissipate heat for the electrical components. When the electrical components or the cabinet are to be repaired, the side wall of the cabinet can be removed for maintenance.
