Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the present invention. Detailed Implementation

[0012] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0013] The specific technical solution of this utility model is as follows:

[0014] like Figure 1 As shown, a moisture-proof nitrogen cabinet includes a box body. Inside the box body, there is a nitrogen cabinet 1 and a storage cabinet 2. The nitrogen cabinet 1 is equipped with a first nitrogen tank 3 and a second nitrogen tank 4. The top of the storage cabinet 2 is equipped with a buffer box 5, which is connected to the storage cabinet 2. The buffer box 5 is equipped with a gas sensor 6. The first nitrogen tank 3 and the second nitrogen tank 4 are respectively connected to the buffer box 5 through nitrogen pipes 7.

[0015] The nitrogen pipeline 7 is Y-shaped and includes an outlet 71, a first inlet 72, and a second inlet 73. Valves are provided on both the first inlet 72 and the second inlet 73. The outlet 71 is fixedly connected to the buffer box 5. The first inlet 72 and the second inlet 73 are respectively connected to the first nitrogen tank 3 and the second nitrogen tank 4 through a flange structure. Specifically, the first nitrogen tank 3 and the second nitrogen tank 4 are respectively connected to the buffer box 5 through the Y-shaped nitrogen pipeline 7.

[0016] The outlet 71 of the nitrogen pipeline 7 is connected to the top of the buffer tank 5, the bottom of the buffer tank 5 is connected to the storage cabinet 2, and the gas sensor 6 is located in the middle of the buffer tank 5. Specifically, when the nitrogen in the buffer tank 5 decreases to the level of the gas sensor 6, the gas sensor 6 will alarm and switch the nitrogen tank in time to avoid interruption of nitrogen supply to the storage cabinet 2.

[0017] The nitrogen cabinet 1 is provided with a cabinet door 8 on its side. Two recessed seats 9 are fixed inside the nitrogen cabinet 1. The recessed seats 9 are adapted to the bottom of the first nitrogen tank 3 and the second nitrogen tank 4. The recessed seats 9 have an opening facing the cabinet door 8. A limiting rotating plate 10 is provided on the opening. One end of the limiting rotating plate 10 is set on the recessed seat 9 through a rotating rod 11. A positioning pin 12 is provided on one end of the limiting rotating plate 10. The positioning pin 12 is inserted into the recessed seat 9. Specifically, the first nitrogen tank 3 and the second nitrogen tank 4 are fixed inside the nitrogen cabinet 1 by the recessed seats 9 and the limiting rotating plate 10, which improves stability and facilitates the replacement of nitrogen tanks in the future.

[0018] The inner side of the aforementioned limiting plate 10 is provided with an arc-shaped groove (not shown in the figure) that is compatible with the first nitrogen tank 3 and the second nitrogen tank 4. Specifically, the arc-shaped groove of the limiting plate 10 fits into the first nitrogen tank 3 and the second nitrogen tank 4, which improves the stability of the first nitrogen tank 3 and the second nitrogen tank 4 in the nitrogen cabinet 1.

[0019] In use, the first nitrogen tank 3 delivers nitrogen to the buffer tank 5 through the nitrogen pipeline 7. The nitrogen then enters the storage cabinet 2 through the buffer tank 5, filling both the buffer tank 5 and the storage cabinet 2 with nitrogen, thereby ensuring that the electronic components are always in a nitrogen-filled environment.

[0020] When the nitrogen in the first nitrogen tank 3 is exhausted, and the nitrogen in the buffer tank 5 decreases to the level of the gas sensor 6, the gas sensor 6 will alarm, close the valve of the first air inlet 72, and open the valve of the second air inlet 73, completing the alternation of the first nitrogen tank 3 and the second nitrogen tank 4. The nitrogen in the second nitrogen tank 4 will fill the buffer tank 5, so that the supply of nitrogen to the storage cabinet 2 will not be interrupted, and the electronic components will always be in a nitrogen-filled environment, maintaining excellent dehumidification and moisture-proof effect.

[0021] When using the second nitrogen tank 4, the first nitrogen tank 3 needs to be replaced, and vice versa. Specifically, open the cabinet door 8 of the nitrogen cabinet 1, pull out the positioning pin 12 on the limit plate 10, rotate the limit plate 10, remove the failed nitrogen tank from the slot seat 9, replace it with a new nitrogen tank, reset the limit plate 10 and insert the positioning pin 12 to fix the nitrogen tank, and finally close the cabinet door 8 of the nitrogen cabinet 1.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
