[0027] As Figures 1-7 shown, a multifunctional control cabinet, including cabinet body 1 and the heat dissipation mechanism for the ventilation and heat dissipation of cabinet body 1 inside.Cabinet body 1 rear side's upper and lower both ends are fixedly provided with mounting bracket 3, and mounting bracket 3 both ends are provided with mounting hole 7, and the both sides of cabinet body 1 bottom end are detachably connected with footing 2.Heat dissipation mechanism includes air outlet filter screen assembly 6, air inlet filter screen assembly 9 and air suction fan 8, and cabinet body 1 top end and bottom end are provided with upper ventilation opening and lower ventilation opening respectively, air outlet filter screen assembly 6 and air inlet filter screen assembly 9 are installed in upper ventilation opening and lower ventilation opening respectively, air suction fan 8 is installed on air inlet filter screen assembly 9, and located in the inside of cabinet body 1.

[0028] When hanging wall installation is carried out, cabinet body 1 is moved to the lateral wall installation place of room, lets mounting hole 7 align the threaded rod on the aluminum alloy section bar of lateral wall installation place, then moves cabinet body 1, lets the threaded rod pass through mounting hole 7, thereby cabinet body 1 is hung on the lateral wall of room.When floor installation is carried out, cabinet body 1 is moved, and the two footings 2 at the bottom end of the cabinet body 1 are placed on the installation position on the floor of the room.During heat dissipation, start air suction fan 8, and air suction fan 8 will carry out air suction through lower ventilation opening, and the gas passes through air inlet filter screen assembly 9 and enters the inside of cabinet body 1, and then is discharged through upper ventilation opening and air outlet filter screen assembly 6.

[0029] Air inlet filter screen assembly 9 includes filter outer layer 12 and electrostatic adsorption inner layer 13, filter outer layer 12 is detachably connected on the bottom end of cabinet body 1, and covers the bottom end of lower ventilation opening, electrostatic adsorption inner layer 13 is detachably connected air suction fan 8 and filter outer layer 12, and is located in lower ventilation opening, and air outlet filter screen assembly 6 and air inlet filter screen assembly 9 are identical in structure.

[0030] The outer filter layer 12 is detachably connected to the cabinet 1 via screws. The electrostatic adsorption inner layer 13 is detachably connected to the exhaust fan 8 and the outer filter layer 12 via screws. The outer filter layer 12 can be removed from the cabinet 1 and the electrostatic adsorption inner layer 13 for separate cleaning. The electrostatic adsorption inner layer 13 can capture micro-dust, which is existing technology and will not be described in detail here. The outer filter layer 12 of the exhaust filter assembly 6 is also detachably connected to the top of the cabinet 1 via screws and covers the upper vent. The electrostatic adsorption inner layer 13 of the exhaust filter assembly 6 is detachably connected to the outer filter layer 12 via screws and is located inside the upper vent.

[0031] Two L-shaped connecting plates 10 are fixedly installed at both ends of the foot 2. The connecting plate 10 has a connecting hole 11 at the end away from the foot 2. A connecting screw is installed in the connecting hole 11. The connecting screw is threaded to the cabinet 1. The foot 2 is detachably connected to the cabinet 1 through the connecting plate 10 and the connecting screw.

[0032] When installing foot 2, first place foot 2 at the bottom of cabinet 1, so that the connecting hole end of connecting plate 10 abuts against the bottom surface of cabinet 1. Then, pass the connecting screw through the connecting hole 11 and thread it onto cabinet 1. When removing foot 2, unscrew the connecting screw from cabinet 1 and move it away from the connecting hole 11 to remove foot 2.

[0033] An anti-slip pad is fixed at the bottom of foot 2.

[0034] The anti-slip mat can increase the friction at the bottom of the feet 2, improve the stability of the cabinet 1, and prevent the cabinet 1 from easily sliding when it is installed on the ground.

[0035] Two hanging rings 4 are fixedly installed on the left and right sides of the top of the cabinet 1.

[0036] The lifting ring 4 facilitates the hoisting of the cabinet 1, allowing the cabinet 1 to be hoisted and moved to the installation location on the side wall of the room.

[0040] When the temperature sensor detects that the temperature inside cabinet 1 exceeds the set threshold (e.g., 35°C), it sends a signal to the control module. The control module then controls the exhaust fan 8 to start, evacuating air and cooling the interior of cabinet 1. When the temperature sensor detects that the temperature inside cabinet 1 drops below the set threshold (e.g., 35°C), it sends a signal to the control module, which then controls the exhaust fan 8 to stop operating.

[0041] The cabinet 1 is equipped with high-voltage terminal blocks and low-voltage signal terminal blocks. The high-voltage terminal blocks and low-voltage signal terminal blocks are separated and isolated, thereby realizing the modular layout of the internal components of the cabinet 1.

[0042] The components inside cabinet 1 are arranged in a partitioned modular layout, which can achieve isolation between strong and weak currents and reduce electromagnetic interference.

[0043] The mounting bracket 3 is a straight strip plate, the width of which is greater than the width of the cabinet 1. The part of the mounting bracket 3 that extends beyond the cabinet 1 forms two mounting arms. The mounting hole 7 is a waist hole and is located on the mounting arm, so as to facilitate the wall mounting of the cabinet 1 by exposing the mounting hole 7.
