Multiple axial fans 3 are connected to the support plate 2, and a cabinet door 7 is rotatably connected to one side of the cabinet 1. A plurality of hinges 8 are rotatably connected between the cabinet 1 and the cabinet door 7, and a plurality of exhaust outlets 6 are connected to the cabinet door 7.

[0026] The cabinet 1 and the door 7 form the main body of an electrical box. The door 7 is installed on the cabinet 1 through a hinge 8, and the cabinet door 7 is opened and closed by a hinge connection. The electrical cabinet should also be provided with a door lock, a handle, and a control button between the cabinet 1 and the door 7. These components are modules and parts that are compatible with conventional electrical boxes and belong to the prior art. Therefore, they will not be described in detail here. The cabinet 1 contains a large amount of space for installing circuit equipment, electronic instruments, etc. There is a separate space behind it, namely the compartment 4, which is separated from the space for installing instruments in the cabinet 1 by a support plate 2, and an appropriate amount of support plate 2 is installed on the support plate 2. And there are enough axial fans 3, which blow the air from one end of the compartment 4 with the air inlet 5 into the equipment compartment of the cabinet 1, and then blow the hot air coiled in the equipment compartment out through the exhaust vents 6 on the cabinet door 7, so as to achieve a good heat dissipation effect. In addition, baffles and filters are provided at each air inlet 5 and exhaust vent 6 to prevent dust from being brought into the interior of the cabinet 1 when the air circulates in and out of the box. Here, good heat dissipation and dust prevention effects are provided, and a better operating environment is provided for the electrical equipment in the electrical cabinet. From the perspective of reducing the probability of failure, the frequency of electrical cabinet maintenance is reduced, and certain conveniences are provided for the electrical cabinet maintenance work.

The No. 2 motor 15 is connected to the drive block 13 at the end of the screw 14 away from the limiting frame 17. In this way, the No. 2 motor 15 serves as the power provider for the rotation of the screw 14, and together with the screw 14, moves up and down on the stud 10 as the drive block 13 moves. The limiting frame 17 is located above and below the screw 14 and is connected with a slide groove 18. The upper and lower ends of the drive frame 16 are connected with a slide rod 19 that cooperates with the slide groove 18. The slide rod 19 passes through the slide groove 18 and is slidably connected to the limiting frame 17. While providing limiting conditions for the drive frame 16, it also provides an auxiliary support effect for it.

[0029] The camera 20 is used to shoot and inspect the circuit components in the electrical cabinet, instead of personnel running around between each electrical cabinet and opening the electrical cabinets for inspection one by one. It can also help reduce the frequency of maintenance and extend the maintenance period. The camera 20 has functions such as photography, transmission, and lighting, and is also a type of common camera 20. It is installed on the drive frame 16 and is rotated by the screw 14 and the stud 10 respectively to achieve horizontal and vertical movement in the cabinet 1. This part of the mechanism is fixed on the inside of the cabinet door 7 and will not take up too much space inside the electrical cabinet. Two studs 10 are installed at the left and right ends of the cabinet door 7. A drive block 13 is set on the stud 10, and the screw 14 is horizontally arranged between the two drive blocks 13. The rotation of the stud 10 and the screw 14 is achieved by the operation of motor No. 11 and motor No. 2 15 respectively, and both motors are forward and reverse motors.

[0030] During the specific implementation of the present invention, the axial flow fan 3 in the cabinet 1 is constantly running during the daily operation of the electric cabinet, continuously sending the colder air from the outside into the cabinet 1 and squeezing out the hotter air in the cabinet 1. In addition, shields are provided above the air inlet 5 and the air outlet 6 on the electric cabinet to prevent dust from entering. This continuously provides a good environment for the operation of the equipment in the electric cabinet. At the same time, the camera 20 on the inside of the cabinet door 7 is also running under the operation of the No. 1 motor 11 and the No. 2 motor 15, continuously monitoring the equipment, lines, connectors and other components in the electric cabinet. When an abnormal situation is found, it can be reported to the corresponding monitoring terminal at any time. The corresponding monitoring terminal can also inspect the situation inside the electrical cabinet at any time through a camera. The corresponding control module or data module is also set in the electrical cabinet. Through the daily maintenance and real-time monitoring of the electrical cabinet itself, the frequent manual maintenance of the electrical cabinet is replaced. Under this relatively safe and secure measure, the frequency of personnel coming to the electrical cabinet, opening the electrical cabinet door 7, and performing maintenance inspections on the internal situation can be greatly reduced, making maintenance work more convenient and easy.

[0031] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
