Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification of distribution boxes, in particular to a dehumidification device for distribution boxes. Background Art

[0002] The distribution box is a key mechanism for modern power transmission. It is used to assemble electrical appliances for power distribution, so that electric energy is distributed to lower-level distribution equipment in different locations, ensuring the reasonable distribution and output of power between power facilities. During the use of the distribution box, external humid air can easily enter the distribution box. If the air humidity in the distribution box is too high, the insulation performance of the electrical equipment inside the distribution box may be reduced, increasing the risk of leakage and short circuit. At the same time, a long-term high-humidity environment may also cause equipment corrosion and damage, shortening its service life. Therefore, a dehumidification device for a distribution box is needed to solve the above problems. Utility Model Content

The dehumidification structure 4 includes a rectangular frame 15, a non-woven bag 16 is fixedly installed on the inner wall of the rectangular frame 15, and the non-woven bag 16 is filled with calcium chloride desiccant. Two mounting rods 17 are symmetrically fixedly installed on the outer wall of the rectangular frame 15. The dehumidification structure 4 is installed in a fixed structure 3. An air intake window 6 is provided on the left wall of the distribution box body 1, and a protective net 8 is fixedly installed in the air intake window 6. An air outlet window 7 is provided on the right wall of the distribution box body 1. A protective door 5 is installed at the front end of the distribution box body 1, and a ventilation exhaust fan 2 is fixedly installed in the air outlet window 7. The dehumidification structure 4 is located on the inner side of the air intake window 6. The rectangular frame 15 is located in the U-shaped bracket 9 and the U-shaped limit frame 13, and the mounting rod 17 is inserted in the slot 10. By arranging the dehumidification structure 4 on the inner side of the air intake window 6 on the distribution box body 1, and cooperating with the ventilation exhaust fan 2, when the ventilation exhaust fan 2 discharges the high-calorie air in the distribution box body 1, thereby dissipating the heat in the distribution box body 1, the external humid air will enter the distribution box body 1 through the air intake window 6 and the dehumidification structure 4. At this time, the calcium chloride desiccant in the dehumidification structure 4 can absorb the moisture in the humid air, so that the air entering the distribution box body 1 is relatively dry, thereby avoiding the air humidity in the distribution box body 1 being too high, and finally reducing the risk of damage to the electrical equipment in the distribution box body 1.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a fixed structure 3 is installed on the left inner wall of the distribution box body 1, and the fixed structure 3 is composed of a U-shaped bracket 9, a fixed spring 11, a guide rail 12 and a U-shaped limit frame 13. The U-shaped bracket 9 is fixedly installed on the left inner wall of the distribution box body 1, and the fixed spring 11 has two and is symmetrically fixedly installed on the upper end of the U-shaped bracket 9. The guide rail 12 is fixedly installed on the left inner wall of the distribution box body 1, and the guide rail 12 is also located above the U-shaped bracket 9. The U-shaped limit frame 13 is fixedly installed on the upper ends of the two fixed springs 11, and The U-shaped limit frame 13 is slidably installed on the guide rail 12 at the same time.

[0021] It should be noted that the utility model is a dehumidification device for a distribution box. During use, the electrical equipment installed in the distribution box body 1 will generate a certain amount of heat. When the ventilation exhaust fan 2 is started to discharge the hot air in the distribution box body 1 through the air outlet window 7, the external air will enter the distribution box body 1 through the air inlet window 6 and the dehumidification structure 4. At this time, the calcium chloride desiccant in the dehumidification structure 4 can absorb the moisture in the humid air, so that the air entering the distribution box body 1 is relatively dry, thereby avoiding excessive air humidity in the distribution box body 1, and finally reducing the risk of damage to the electrical equipment in the distribution box body 1. When the dehumidification structure 4 needs to be replaced after being used for a period of time, the dehumidification structure 4 can be grasped first, and then the dehumidification structure 4 can be pushed up. At this time, the dehumidification structure 4 will push the U-shaped limit frame 13 on the fixed structure 3 upward, so that the U-shaped limit frame 13 slides upward on the guide rail 12. At this time, the fixed spring 11 will be stretched and deformed. When the installation rod 17 on the dehumidification structure 4 is removed from the slot 10, the dehumidification structure 4 can be taken out from between the U-shaped bracket 9 and the U-shaped limit frame 13, and then the new dehumidification structure 4 can be installed in the fixed structure 3, so that the installation rod 17 can be inserted into the slot 10 under the elastic force of the fixed spring 11.
