[0024] One end of the shell 1 is an open end 3, and the load prediction device body 2 is arranged at the bottom inside the shell 1 through the open end 3, and the output display end of the load prediction device body 2 corresponds to the open end 3. The open end 3 of the shell 1 is provided with a cover 20, and the cover 20 is snap-connected with the shell 1. An observation port 21 is opened on the cover 20. The observation port 21 is the same size as and corresponds to the output display end of the load prediction device body 2. A plurality of parallel support plates 22 are provided at the bottom and back of the load prediction device body 2, and a guide groove 23 is formed between adjacent support plates 22. The support plates 22 are also made of metal copper, and copper has good thermal conductivity.

[0025] A number of copper plates 4 for cooling the temperature are arranged between the shell 1 and the load prediction device body 2, a temperature sensor 7 is installed on the copper plate 4, and the temperature sensor 7 is fixedly connected to the mounting frame 10, and cooling fans 6 are respectively installed on the sides corresponding to the shell 1 and the copper plate 4, and the cooling fan 6 is directly opposite to the copper plate 4, and the copper plate 4 and the shell 1 are slidably matched, and an adjustment component 5 for adjusting the movement of the copper plate 4 is arranged between the copper plate 4 and the shell 1, and the adjustment component 5 includes a mounting frame 10, a spring 11, a telescopic rod 12 and a block 13, the mounting frame 10 is fixedly connected to the copper plate 4, the spring 11 is located between the mounting frame 10 and the shell 1, and the two ends of the spring 11 are respectively fixedly connected to the mounting frame 10 and the shell 1, the telescopic rod 12 is located in the spring 11 and is concentric with the spring 11, and the two ends of the telescopic rod 12 are respectively fixedly connected to the mounting frame 10 and the shell 1, and a slide groove 14 is opened on the mounting frame 10, and the block 13 is slidably arranged inside the slide groove 14, and the other end of the block 13 is in contact with the shell 1.

[0026] A control unit 8 is provided at the bottom of the housing 1, and the control unit 8 includes a power supply 15, a controller 16 and an installation box 17.

[0027] Working principle:

[0028] The output display end of the load prediction device body 2 can be operated through the observation port 21. The copper plate 4 is in close contact with the side of the load prediction device body 2. Copper has good thermal conductivity and can quickly dissipate heat from the load prediction device body 2. The temperature sensor 7 detects the surface of the copper plate 4 in real time. The temperature sensor 7 transmits the detected temperature to the controller 16 in real time. When the output temperature of the temperature sensor 7 reaches the threshold set by the controller 16, the controller 16 controls the cooling fan 6 to start, and the cooling fan 6 cools the copper plate 4 to ensure the cooling effect.

[0029] When the load prediction device body 2 needs to be inspected and repaired, the user first takes out the cover 20 and then pulls out the block 13. The block 13 will remove the restriction on the mounting frame 10, so that the mounting frame 10 will drive the copper plate 4 to move toward the direction close to the outer shell 1 under the elastic force of the spring 11, thereby separating from the side of the load prediction device body 2. The telescopic rod 12 is used to limit the moving range of the copper plate 4 and at the same time ensure the stability of the movement of the copper plate 4. When the three copper plates 4 are separated from the side of the load prediction device body 2, the load prediction device body 2 can be taken out for maintenance, avoiding the trouble of direct extraction and ensuring the service life of the load prediction device body 2.
