[0031] When in use, the sealed door 2 is opened, and the power-off assembly 4 automatically cuts off the power, thereby preventing dust from entering the interior and causing a short circuit. When the sealed door 2 needs to be closed, the sealed door 2 is closed, and the lock block 303 on the first mounting block 304 is driven to move within the movable hole 301 by rotating the handle 302, so that the lock block 303 is inserted into the lock hole 305. Then, the handle 302 is rotated to lock the sealed door 2 with the box body 1, thereby preventing the sealed door 2 from being accidentally opened during use by the control device body 8. During use, the present invention can dissipate heat from the internal equipment through the heat dissipation assembly 7.
[0032] The power-off component 4 includes a second mounting block 401, a first copper sheet 402, a second copper sheet 403, a connecting line 404, a third mounting block 405 and a third copper sheet 407.

[0034] A spring 406 is fixedly installed between the third mounting block 405 and the third copper sheet 407 . A sealing cover 408 is fixedly connected to the outer wall of the third mounting block 405 . The sealing cover 408 can cover the outer wall of the second mounting block 401 .
[0035] The spring 406 is installed between the third mounting block 405 and the third copper sheet 407. When the sealing door 2 is closed, the spring 406 is in a compressed state, so that the third copper sheet 407 fits tightly with the first copper sheet 402 and the second copper sheet 403, ensuring good conductive performance; the sealing cover 408 is fixedly connected to the outer wall of the third mounting block 405. When the sealing door 2 is closed, the sealing cover 408 covers the outer wall of the second mounting block 401, playing a role of sealing and dustproofing.
[0036] The heat dissipation assembly 7 includes a fan 701, a pulley 702, a drive belt 703 and a drive motor 704.

The drive motor 704 is fixedly installed on the inner wall of the box 1. The pulley 702 at the bottom is fixedly installed on the output end of the drive motor 704.
[0037] When in use, the drive motor 704 is started, and the output end of the drive motor 704 drives the pulley 702 at the bottom to rotate, and drives the pulley 702 at the rear end of the fan 701 to rotate through the drive belt 703, so that the fan 701 rotates inside the box 1 to generate airflow and achieve heat dissipation.
[0038] The front ends of the two fans 701 are fixedly connected to the support shaft 705, and the inner wall of the box body 1 is fixedly connected to the support frame 706. There are two support frames 706. The inside of the support frame 706 is fixedly installed with a bearing 707, and the support shaft 705 is fixedly installed in the inner ring of the bearing 707.
[0039] When the fan 701 rotates, the support shaft 705 rotates in the inner ring of the bearing 707, providing stable support for the fan 701, while making the fan 701 rotate more smoothly, improving the working efficiency of the fan 701 and extending its service life.
[0040] An air inlet slot 102 is provided at the rear end of the box body 1 , and air outlet slots 103 are provided on both sides of the box body 1 . Dust-proof filters are installed inside the air inlet slot 102 and the air outlet slot 103 .
[0041] The airflow generated during the rotation of the fan 701 is sucked in through the air inlet slot 102, filtered by the dust filter, and then enters the interior of the box 1. The airflow takes away heat when passing through the electronic components on the mounting rack 5, and is then discharged through the air outlet slot 103.
[0042] A hinge 202 is fixedly connected between the box body 1 and the sealed door 2. An observation window 201 is provided inside the sealed door 2. Tempered glass is embedded in the observation window 201.
[0043] During use, the hinge 202 allows the sealed door 2 to be easily opened and closed; the observation window 201 is provided inside the sealed door 2 for convenient observation of the situation inside the box body 1 .
[0044] The bottom of the box body 1 is fixedly connected with supporting legs 101 , and there are four supporting legs 101 distributed in a rectangular shape.
[0045] When in use, the support legs 101 can provide stable support for the box body 1 to prevent the control device body 8 from shaking during use.
[0046] Working principle: First, install the utility model to the designated position, provide stable support through the support feet 101, connect the power cord 6 to the external power supply, and when the sealed door 2 is closed, insert the lock block 303 at the front end of the handle 302 into the lock hole 305 to lock the sealed door 2 and the box body 1. At this time, the third copper sheet 407 of the power-off component fits with the first copper sheet 402 and the second copper sheet 403 to form a passage to supply power to the control device body 8.
[0047] Then start the drive motor 704, and the output end of the drive motor 704 drives the pulley 702 at the bottom to rotate, and drives the pulley 702 at the rear end of the fan 701 to rotate through the drive belt 703, so that the fan 701 rotates inside the box 1 to generate airflow, and the air outside the box 1 is sucked in through the air inlet slot 102, and then enters the inside of the box 1 after being filtered by the dustproof filter. The airflow takes away heat when passing through the electronic components on the mounting bracket 5, and is then discharged through the air outlet slot 103.
[0048] When the control device body 8 needs to be inspected or operated, the sealed door 2 is opened. At this time, the third mounting block 405 of the power-off assembly is separated from the second mounting block 401, and the third copper sheet 407 is disconnected from the first copper sheet 402 and the second copper sheet 403, thereby achieving automatic power-off and improving safety. During the inspection or operation process, the situation inside the box body 1 can be observed through the observation window 201.
[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
