DETAILED DESCRIPTION

[0020] 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.

[0021] Refer to the instruction manual Figure 1-4 ,like Figure 1 As shown, a dehumidification type transformer neutral point grounding resistance cabinet according to an embodiment of the utility model comprises a cabinet body 1, as shown Figure 2As shown, an air inlet pipe 2 is connected to one side of the cabinet 1, a base 3 is fixedly installed on the outer side of the air inlet pipe 2, a closing piece 4 is rotatably connected to one side of the cabinet 1, the closing piece 4 and the base 3 are arranged in a close fit, a handle 5 is fixedly installed on one side of the closing piece 4, an extension rod 6 is fixedly installed on one side of the closing piece 4, a first shaft column 7 is sleeved inside the extension rod 6, a transmission rod 8 is fixedly installed on one end of the first shaft column 7, a storage column 9 is fixedly installed on one side of the cabinet 1, an internal threaded tube 10 is sleeved on the outer side of the storage column 9, a rubber telescopic tube 11 is fixedly installed on one side of the internal threaded tube 10, an adapter 12 is fixedly installed on one side of the rubber telescopic tube 11, and the adapter 12 is sleeved on the outer side of the storage column 9, as shown in FIG. Figure 3 As shown, a second shaft rod 13 is sleeved inside the transmission rod 8 .

[0022] It should be noted that, when the resistance cabinet needs to be dehumidified, the closure 4 is turned over by pulling the handle 5 and leaves the port of the air inlet pipe 2. At this time, the internal threaded tube 10 is removed from the outside of the storage column 9, the internal threaded tube 10 is threadedly connected and fixed to the air inlet pipe 2, the rubber telescopic tube 11 is stretched to extend the overall length, and the adapter 12 is plugged into the air outlet end of the hot air blower. At this time, the hot air blower is started to input the hot air into the interior of the cabinet 1 through the rubber telescopic tube 11, thereby drying the moisture inside the cabinet 1. At the same time, when the closure 4 is turned over, it will also drive the transmission The rod 8 moves, thereby causing the connecting rod 14 to flip to one side synchronously through the transmission rod 8. When the connecting rod 14 flips, the top cover 17 will be driven to flip through the connecting rod 15, and then the top cover 17 will be opened. When the hot air enters the cabinet 1 to dry the moisture, the moisture will be blown out from the inside of the cabinet 1, thereby accelerating the dehumidification efficiency. After the moisture in the cabinet 1 is removed, the air inlet pipe 2 can be closed, and the internal threaded tube 10 can be put on the outside of the storage column 9, so that the hot air blower can be collected or other resistance cabinets can be dehumidified, thereby reducing the cost of dehumidification.

[0023] Further, such as Figure 3 As shown, the outer side of the second shaft rod 13 is rotatably connected with a connecting rod 14, one end of the second shaft rod 13 is fixedly installed with a connecting rod 15, the top of the cabinet 1 is fixedly installed with a support 16, and the connecting rod 14 is rotatably connected to one side of the support 16, as shown in FIG. Figure 4 As shown, a top cover 17 is hinged on the top of the cabinet 1, a connecting rod 15 is fixedly installed on the outside of the top cover 17, a protective mesh plate 18 is fixedly installed inside the cabinet 1, a ventilation fan 19 is rotatably connected to the bottom of the protective mesh plate 18, the ventilation fan 19 is rotatably connected to the inside of the cabinet 1, a motor 20 is fixedly installed on the top of the protective mesh plate 18, and the ventilation fan 19 is fixedly installed at the output end of the motor 20.

[0024] It should be noted that, when dehumidification is performed, the motor 20 is turned on to rotate the ventilation fan 19, thereby forming suction on the inside of the cabinet 1, and transporting moisture and steam generated by drying to the outside of the cabinet 1, thereby further improving the dehumidification efficiency. After the dehumidification is completed, the top cover 17 can seal the top of the cabinet 1 to prevent dust from entering the inside of the cabinet 1.
