[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] The embodiments of the present application disclose a sulfur hexafluoride gas leakage alarm device.

[0023] Reference Figure 1 and Figure 2 , including an alarm box 1 and a sulfur hexafluoride analysis shell 2. The sulfur hexafluoride analysis shell 2 is located in the alarm box 1. Four support frames 3 are placed horizontally inside the alarm box 1. Two support frames 3 are located at the lower end of the sulfur hexafluoride analysis shell 2, and the other two support frames 3 are located at the sulfur hexafluoride analysis shell 2.

[0024] Four placement grooves 4 are opened on the inner side wall of the alarm box 1 , one end of the support frame 3 is rotated in one end of the installation groove, and the support frame 3 is rotatably embedded in the placement groove 4 .

[0025] Reference Figure 2 、 Figure 3 and Figure 4 The support frame 3 includes a support rod 5 and a gear rod 6. One end of the gear rod 6 is rotatably connected to one end of the support rod 5. A first rotation hole is opened in one end of the gear rod 6, and a second rotation hole is opened in one end of the support rod 5. The first rotation hole and the second rotation hole are correspondingly arranged. A locking rod 7 is inserted and fixed in the first rotation hole and the second rotation hole. The locking rod 7 is a square strip. The four support frames 3 are rotated out of the placement slots 4 so that the support frames 3 are perpendicular to the inner side walls of the alarm box 1. The sulfur hexafluoride analysis shell 2 is placed on two support frames 3, and the other two support frames 3 are located at the upper end of the sulfur hexafluoride analysis shell 2. Then, the gear lever 6 is rotated so that the gear lever 6 and the support rod 5 are in a vertical state. Then, the locking rod 7 is inserted into the gear lever 6 and the support rod 5 in turn to stabilize them so that the side walls of the gear lever 6 abut against the outer side walls of the sulfur hexafluoride analysis shell 2, thereby restricting the sulfur hexafluoride analysis shell 2 in the alarm box 1. Conversely, when disassembling the sulfur hexafluoride analysis shell 2, just pull out the locking rod 7 from the gear lever 6 and the support rod 5, and then rotate the gear lever 6 so that the gear lever 6 and the support rod 5 are in the same straight line. Then, the sulfur hexafluoride analysis shell 2 can be taken out from between the four support frames 3.

[0026] The support rod 5 includes a fixed rod 8 and a sliding rod 9. One end of the sliding rod 9 is integrally provided with a plug-in rod 10. The plug-in rod 10 includes an insert rod 11 and two limit rods 12. The two limit rods 12 are respectively fixed on the corresponding two sides of the insert rod 11. One end of the fixed rod 8 is rotatably connected to one end of the placement slot 4. The outer end of the fixed rod 8 is provided with a plug-in slot 17 for the plug-in rod 10 to plug and slide. The upper and lower side walls of the plug-in slot 17 are through-opened. A tension spring 13 is horizontally placed between the plug-in rod 10 and the bottom of the plug-in slot 17. One end of the tension spring 13 is fixed to the outer end of the plug-in rod 10, and the other end of the tension spring 13 is fixed to the bottom of the plug-in slot 17. The tension spring 13 drives the sliding rod 9 and the fixed rod 8 to approach each other. When encountering different models of sulfur hexafluoride analysis housings 2, the plug-in rod 10 of the sliding rod 9 can be slid in the plug-in groove 17 in the fixed rod 8 to adjust the length of the support rod 5. When the support frame 3 supports the sulfur hexafluoride analysis housing 2, the sliding rod 9 is pulled by the tension spring 13, so that one side of the gear lever 6 always abuts against the outer wall of the sulfur hexafluoride analysis housing 2.

[0027] Two stabilizing rods 14 are positioned horizontally below the two support frames 3 located below the sulfur hexafluoride analysis housing 2. Four embedding slots 15 are defined on the inner sidewall of the alarm box 1, with each pair of these slots 15 located below the two support frames 5. One end of each stabilizing rod 14 is pivotally connected to the upper end of each slot 15. Stabilizing slots 16 are defined on both sides of the underside of the fixed rod 8, with the outer ends of each stabilizing rod 14 inserted and fixed into these slots. After the sulfur hexafluoride analysis housing 2 is installed, the stabilizing rods 14 are rotated out of the slots 15 and then inserted into the slots 16, thereby improving the stability of the support frames 3.

[0028] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
