[0026] In use, the equipment partition 8 and the U-shaped channel 15 are fixed by the fixing component 9. The positioning hole on the equipment partition 8 is aligned with the fixing hole on the surface of the U-shaped channel 15. First, the fixing baffle 93 is pinched and the fixing rod 92 is inserted into the inside of the fixing cylinder 91. Then, the screw 94 is inserted into the threaded hole on the surface of the fixing rod 92 and tightened. The screw 94 is then lowered down along the slide to fix the equipment partition 8 and the U-shaped channel 15.

[0027] See Figure 5 , Figure 6 and Figure 8Furthermore, the dehumidification mechanism includes a storage component 10, and a dehumidification component 11 is fixedly connected below the connection between the storage component 10 and the cabinet 2. The storage component 10 includes a storage box 101, a sealing cover 102 is provided at the top of the storage box 101, a sealing strip is fixedly connected inside the sealing cover 102, and a transmission cylinder 104 is fixedly connected to the bottom of the storage box 101.

Two sliding grooves 16 are opened above the connection between the fixing plate 134 and the cabinet 2.

[0028] In use, when dehumidification of the interior of cabinet 2 is required, the storage component 10, the dehumidification component 11, and the lifting component 13 will work together. First, open the sealing cover 102 on the top of the storage box 101 and pour in the calcium chloride granules. The calcium chloride granules will enter the dehumidification box 111 through the transfer cylinder 104. Normally, the valve 103 at the bottom of the storage box 101 will prevent the calcium chloride granules from falling down. Only when the dehumidification box 111 needs to be filled, the valve 103 will be manually opened to allow the calcium chloride to fall down. The surface of the dehumidification box 111 has an air inlet 112, through which moisture will enter the interior of the dehumidification box 111. Because the bottom of the dehumidification box 111 is equipped with a water-permeable mesh, the calcium chloride granules will not fall down, only... It can filter water. When moisture reacts chemically with the calcium chloride inside, water is formed. This water enters the water storage box 12 through the hose 113. Since the water storage box 12 is placed on the shelf 131, there is a slider 132 on one side of the shelf 131 and a spring 133 at the bottom. When there is a lot of water in the water storage box 12, the water storage box 12 will exert pressure on the shelf 131.

The alarm light 5 is connected to the external power supply through the switch button 14. When the switch button 14 is pressed, the alarm light 5 will light up, prompting the staff to empty the water in the water storage box 12.

[0029] In this embodiment, the following steps are taken during use: First, open the cabinet door 3. Then, insert the equipment partition 8 into the U-shaped groove 15. Fix the equipment partition 8 to the U-shaped groove 15 using the fixing component 9. Align the positioning holes on the equipment partition 8 with the fixing holes on the surface of the U-shaped groove 15. First, pinch the fixing baffle 93 and insert the fixing rod 92 into the fixing cylinder 91. Then, insert the screw 94 into the threaded hole on the surface of the fixing rod 92 and tighten it. Lower the screw 94 along the slide rail to fix the equipment partition 8 to the U-shaped groove 15. Place the equipment on the equipment partition 8 and install it inside the cabinet 2. The four support legs 4 at the bottom of the cabinet 2 can keep the cabinet 2 away from the ground, which is beneficial for protection. Moisture-proof and insect-proof, the protective canopy 1 is fixedly installed on the top of the cabinet 2 to prevent dust or debris from falling in. When the space separated by the original equipment partition 8 is insufficient to add new equipment, the equipment partition 8 can be adjusted. By placing the screw 94 in the slide rail and lifting it upwards, the fixing rod 92 can be raised, and then the equipment partition 8 can be pulled out and placed in a suitable position. A dustproof net 6 is provided at the bottom of one side of the cabinet 2, and an exhaust fan 7 is provided at the top of the other side. When the exhaust fan 7 is working, it will create convection, which can not only dissipate heat but also remove dust. When it is necessary to dehumidify the inside of the cabinet 2, the storage component 10, the dehumidification component 11, and the lifting component 13 will work together. First, Open the sealing cover 102 on the top of the storage box 101 and pour in the calcium chloride granules. The calcium chloride granules will enter the dehumidification box 111 through the transfer cylinder 104. Normally, the valve 103 at the bottom of the storage box 101 will prevent the calcium chloride granules from falling in. Only when the dehumidification box 111 needs to be filled, the valve 103 will be manually opened to allow the calcium chloride to fall in. The surface of the dehumidification box 111 has an air inlet 112, through which moisture will enter the dehumidification box 111. Because the bottom of the dehumidification box 111 is equipped with a water filter, the calcium chloride granules will not fall in; only water will be filtered. When the moisture reacts chemically with the calcium chloride inside, it will form... The water is formed and enters the water storage box 12 through the hose 113. Since the water storage box 12 is placed on the shelf 131, the shelf 131 has a slider 132 on one side and a spring 133 at the bottom. When there is a lot of water in the water storage box 12, the water storage box 12 will exert pressure on the shelf 131. The slider 132 on one side of the shelf 131 will move down in the slide groove 16. When it moves close to the fixed plate 134, it will press the switch button 14. The alarm light 5 is connected to the external power supply through the switch button 14. When the switch button 14 is pressed, the alarm light 5 will light up, prompting the staff to empty the water in the water storage box 12.
