[0036] As Figures 1-6 shown, it shows an explosion pressure relief mechanism for a gas pressure regulating tank in an embodiment of the present disclosure, comprising:

[0037] The tank body 1 is an open structure at the top;

[0038] The top cover 2 and the pressure relief connecting assembly 4 are arranged between the top cover 2 and the tank body 1.

[0039] A pair of inner partitions 3 are arranged in the box 1 on both sides, and a protective exhaust assembly 5 is arranged on both sides of the box 1;

[0040] The pressure relief connecting assembly 4 comprises a plurality of inner protrusions 4-1 arranged at the top four corners of the box 1, and the inner protrusions 4-1 are located between the inner partition 3 and the inner wall of the box 1. The surface of the inner protrusion 4-1 is provided with a through hole 4-2, and the bottom surface of the top cover 2 is provided with a plurality of connecting grooves 4-3. The connecting grooves 4-3 are inserted with a buffer bracket 4-4 which is fixedly connected with the box 1 by bolts. The buffer bracket 4-4 is provided with a center rod 4-5, and the center rod 4-5 and the buffer bracket 4-4 are inserted into the through hole 4-2. The center rod 4-5 is sleeved with a buffer spring 4-6, and the center rod 4-5 and the buffer bracket 4-4 are movably sleeved with a limiting plate 4-7 at the lower end. The buffer spring 4-6 is supported between the inner protrusion 4-1 and the limiting plate 4-7. The lower end of the center rod 4-5 is provided with an external thread layer 4-8, and the external thread layer 4-8 is rotatably connected with a fixing nut 4-9 which is attached to the bottom surface of the limiting plate 4-7.

[0041] In some examples, in order to realize the effect of the top cover 2 as a whole for protective pressure relief, a pressure relief connecting assembly 4 is designed. The assembly comprises inner protrusions 4-1 arranged at the top four corners of the box 1, and the inner protrusions 4-1 are located between the inner partition 3 and the inner wall of the box 1. The inner protrusion 4-1 serves as the basic structure connected with the top cover 2. The surface of the inner protrusion 4-1 is provided with a through hole 4-2, and the bottom surface of the top cover 2 is provided with a plurality of connecting grooves 4-3. The connecting grooves 4-3 are inserted with a buffer bracket 4-4 which is fixedly connected with the box 1 by bolts.

The buffer bracket 4-4 is further provided with a center rod 4-5 which is also inserted into the through hole 4-2. The center rod 4-5 is movably sleeved with a limiting plate 4-7 at the lower end of the buffer bracket 4-4. The center rod 4-5 is further sleeved with a buffer spring 4-6. The buffer spring 4-6 is supported between the inner protrusion 4-1 and the limiting plate 4-7 as a supporting force. When the top cover 2 is subjected to an explosion impact, it will move upward in the through hole 4-2 through the buffer bracket 4-4 and the center rod 4-5, and then resist and buffer the impact through the buffer spring 4-6.

[0042] As Figures 1-6As shown, this embodiment proposes a protective exhaust assembly 5 including a pair of inner protective covers 5-1. The inner protective covers 5-1 are installed on both sides of the inner casing 1. The inner protective covers 5-1 have air holes 5-2 on their surfaces. The outer wall of the casing 1 has a rectangular opening 5-3 that is connected to the inner protective covers 5-1. A pair of connecting blocks 5-4 are provided on both sides of the inner protective covers 5-1. A cooling fan 5-5 is inserted into the connecting blocks 5-4. A filter screen 5-6 is inserted into the outer surface of the cooling fan 5-5.

[0043] In some examples, a protective exhaust assembly 5 is designed to achieve a protective exhaust effect. This assembly includes a pair of inner protective covers 5-1 installed on the inner side surfaces of the housing 1. The inner protective covers 5-1 have air holes 5-2 on their surfaces, allowing air to enter through the air holes 5-2 and enabling the inner protective covers 5-1 to have an impact-resistant and explosion-proof effect. The outer wall of the housing 1 has a rectangular opening 5-3 that communicates with the inner protective covers 5-1. A pair of connecting blocks 5-4 are provided on both sides of the inner protective covers 5-1. A cooling fan 5-5 is inserted into the connecting blocks 5-4. A filter screen 5-6 is inserted into the outer surface of the cooling fan 5-5. The cooling fan 5-5 and the filter screen 5-6 are both detachable separate structures, which facilitates disassembly for internal dust cleaning.

[0044] For example, such as Figure 3 As shown, the perforation 4-2 has a cross-shaped structure, and the center of the perforation 4-2 is a circular structure.

[0045] In some examples, the cross-shaped structure perfectly fits the structure of the buffer frame 4-4 and the center rod 4-5, and can be used with the limiting plate 4-7 to fix the buffer spring 4-6 between them.

[0046] For example, such as Figure 1 As shown, the surface of the inner partition 3 has a mesh-like perforated structure.

[0047] In some examples, the mesh-like opening structure provides a certain level of protection without affecting heat dissipation.

[0048] For example, such as Figure 2 As shown, the inner surface of the top cover 2 is a concave structure.

[0049] In some examples, the impact resistance of the top cover 2 is increased by using a concave structural surface.

[0050] In actual use: first, the buffer frame 4-4 is inserted into the connecting groove 4-3 of the top cover 2 and fixed with the box body 1 by bolts, the fixed nut 4-9 is adjusted to make the buffer spring 4-6 reach a suitable buffer strength, the cooling fan 5-5 and the filter screen 5-6 are installed on the connecting block 5-4 of the inner protective cover 5-1, when an explosion occurs in the gas pressure regulating box, the impact force makes the top cover 2 move upward in the perforated hole 4-2 through the buffer frame 4-4 and the center rod 4-5, the buffer spring 4-6 buffers the impact, reduces the damage of the explosion to the box body 1, at the same time, the cooling fan 5-5 of the protective exhaust assembly 5 starts, the gas in the box body 1 is discharged through the air hole 5-2 and the rectangular port 5-3 of the inner protective cover 5-1, and the filter screen 5-6 prevents external impurities from entering.
