[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Reference Figure 1-Figure 4 The utility model provides an embodiment: a protective cabinet for power electronic equipment, including a cabinet 1 and a base 14. The cabinet 1 is provided with a drying and heat dissipation mechanism, which includes a drying box 2, which is fixedly installed on the outside of the cabinet 1, and an air inlet pipe 3 is provided on the drying box 2. A bracket 4 is fixedly connected to the air inlet pipe 3, and a fan 5 is installed on the bracket 4. A drying plate 1 6, a drying plate 2 7, and a drying plate 3 8 are fixedly installed in the drying box 2. A shunt box 9 is connected to one side of the drying box 2, and both sides of the shunt box 9 are fixedly connected to A connecting pipe 10 is provided, one end of which is fixedly connected to an air outlet box 11, and an air outlet hole 12 is provided on the air outlet box 11. External air is sucked into the drying box 2 through the fan 5 and is transmitted to the cabinet 1 after the moisture is removed through the drying plates 1 6, 2 7 and 3 8. The air is discharged from the exhaust hole 13 after heat exchange with the cabinet 1, thereby cooling the cabinet 1 and providing dry air for the cabinet 1 even on relatively humid rainy days, thereby improving the adaptability of the device and facilitating the service life of the device.
[0028] A support column 15 is fixedly connected to the base 14, a fixed block 16 is fixedly connected to the support column 15, a fixed rod 17 is fixedly connected to the fixed block 16, a damping rod 18 is installed between the cabinet 1 and the fixed block 16, a spring 19 is sleeved on the damping rod 18, and both ends of the spring 19 are respectively fixedly connected to the cabinet 1 and the fixed block 16, a connecting rod 20 is hinged at the bottom of the cabinet 1, a sliding ring 21 is hinged at one end of the connecting rod 20, the sliding ring 21 slides and sleeves on the fixed rod 17, a spring 22 is connected between the sliding rings 21, and a connecting column 23 is fixedly connected to the top of the cabinet 1, and the connecting column 2 3 is fixedly connected with a rainproof canopy 24, a side of the cabinet 1 away from the drying box 2 is provided with an exhaust hole 13, a cabinet door 25 is hinged on the cabinet 1, and a handle 26 is provided on the cabinet door 25, and mounting plates 27 are provided on both sides of the base 14, and mounting holes 28 are provided on the mounting plates 27. The energy of the vibration of the cabinet 1 is weakened by the damping rod 18 and the spring 1 19, and the force of the vibration generated by the cabinet 1 can be buffered by the sliding ring 21 and the spring 2 22, which can prevent the loosening of the parts of the device due to vibration, thereby ensuring the working environment of the electronic equipment, which is conducive to further improving the service life of the internal electronic equipment.
[0029] Working principle: The fan 5 draws external air into the drying box 2. The air passes through the drying plate 1 6, the drying plate 2 7, and the drying plate 3 8 to remove moisture and then enters the diversion box 9. After being diverted by the diversion box 9, the air enters the air outlet box 11 from the connecting pipes 10 on both sides, and finally enters the cabinet 1 from the air outlet 12 to cool the electronic equipment in the cabinet 1. The air after heat exchange is discharged to the outside from the exhaust hole 13. When the device vibrates during operation, the vibration force drives the sliding ring 21 to slide back and forth on the fixed rod 17 through the connecting rod 20, thereby continuously compressing and stretching the spring 2 22 to weaken the vibration force. At the same time, the vibration energy is consumed and weakened through the action of the damping rod 18 and the spring 1 19, thereby realizing the shock absorption effect of the cabinet 1 and protecting the internal electronic equipment.
