[0002] An electrical cabinet is a cabinet made of steel materials to protect components to work properly. The manufacturing materials of electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are relatively softer in material and more suitable for the manufacture of electrical cabinets. A large number of electrical components will be placed in the electrical cabinet during use. The function of the power cabinet is to control the electrical equipment to be used and facilitate maintenance when a circuit fails. And the electrical control device is generally called the secondary control circuit of electrical equipment. Different devices have different control circuits, and the control methods of high-voltage electrical equipment and low-voltage electrical equipment are also different. Specifically speaking, an electrical control system refers to a combination of several electrical components used to control a certain object or certain objects, so as to ensure the safe and reliable operation of the controlled equipment. Its main functions are: automatic control, protection, monitoring and measurement. The following problems exist in the prior art:

[0028] As Figure 4 shown in the figure, the present utility model provides a technical solution for an electrical cabinet: A plurality of threaded grooves 601 are equidistantly and arrayed at the rear ends of the two mounting plates 6. The mounting mechanism 7 includes a U-shaped frame 71, two mounting components 72, two positioning plates 73, and two communication holes 74. The two mounting components 72 are respectively arranged on the opposite sides of the U-shaped frame 71 in the vertical direction.

Through holes 74 that penetrate through the front and rear are respectively opened in the middle of the two positioning plates 73. The threaded ends of the communication holes 74 are threadedly connected to the inside of the threaded grooves 601 through the communication holes 74. Through the cooperation of the positioning plates 73, the communication holes 74, the fixing bolts 75, and the threaded grooves 601, it is convenient to adjust the installation height of the U-shaped frame 71.

[0029] AsFigure 5 As shown in the figure, the present utility model provides a technical solution for an electrical cabinet: The installation component 72 includes a clamping plate 721, a screw rod 722 and two springs 725. One end of the knob 723 is fixedly connected to one end of the screw rod 722. The other end of the screw rod 722 is rotatably connected to one end of the second bearing 724. The other end of the second bearing 724 is fixedly connected to one end of the clamping plate 721. One ends of the two springs 725 are respectively fixedly connected to the upper and lower sides close to the second bearing 724. The other ends of the two second bearings 724 are both fixedly connected to the inner side in the vertical direction of the U-shaped frame 71. The end of the clamping plate 721 away from the screw rod 722 is provided with an anti-slip tooth pad 726. Inner threaded pipes 711 are fixedly connected to the middle parts in the vertical direction of the U-shaped frame 71. The outer wall of the screw rod 722 passes through the left and right ends in the vertical direction of the U-shaped frame 71 through the inside of the inner threaded pipe 711 and is threadedly connected therebetween. By rotating the screw rod 722, it is convenient to fixedly install the electrical control device 3 on the U-shaped frame 71 and facilitate disassembly.

[0030] Next, the working principle of this electrical cabinet will be specifically described.

[0031] As Figures 1-5 shown, when installing the electrical control device 3, first, open the cabinet door 2. According to the installation height, fit the U-shaped frame 71 on the two mounting plates 6, and align the communication holes 74 on the positioning plate 73 with the corresponding height threaded grooves 601 on the two mounting plates 6. Then use the fixing bolts 75 to be screwed and fixed in the threaded grooves 601 through the communication holes 74 to complete the installation of the U-shaped frame 71. Then place the electrical control device 3 on the U-shaped frame 71. According to the size of the electrical control device 3, rotate the screw rod 722 along the inside of the inner threaded pipe 711 through the knobs 723 on both sides, so that the clamping plate 721 is driven to move towards one side of the electrical control device 3, and at the same time drive the spring 725 to stretch and move until the anti-slip tooth pad 726 is tightly attached to the outer surface of the electrical control device 3, increasing the friction with the surface of the electrical control device 3 and enhancing the stability of the electrical control device 3 installed on the U-shaped frame 71, and it is also convenient for disassembly. When the electrical cabinet is in use, the stepping motor 50 with the model 2HSS7 is electrically connected to an external power supply through a wire, and the four driving motors 56 are respectively connected to the power supply through wires that are long enough to move back and forth and are inserted out from the wire groove 402. By starting the stepping motor 50 and the driving motors 56, the output shaft of the stepping motor 50 drives the bidirectional lead screw 51 to rotate, so that the two moving blocks 53 move back and forth on the upper and lower sides of the bidirectional lead screw 51 respectively. At the same time, the output shaft of the driving motor 56 drives the fan blade 57 to rotate, so that the outside air enters the cabinet body 1 along a plurality of air outlets 11 on the left side through the filter plate 41, and then drives the hot air in the cabinet body 1 to be blown out through a plurality of air outlets 11 on the right side. The range of the blown air is expanded, accelerating the air circulation in the cabinet body 1, thereby reducing the temperature in the cabinet body 1.

[0032] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made to it, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are within the protection scope of the present utility model.
