[0024] Example 1

[0025] Reference Figure 1 A preferred embodiment of the utility model is a driving pipeline of a fire extinguishing device, comprising an output pipe 7 and a driving pipeline 1 detachably connected to the fire extinguisher, wherein the driving pipeline 1 is provided with a tee 3, and the two outlets of the tee 3 are connected to the output pipe 7 in parallel through a first pipeline 4 and a second pipeline 5, the driving pipeline 1 is provided with a first air bag 2, and the second pipeline 5 is provided with a second air bag 6. Specifically, the fire extinguishing agent (preferably heptafluoropropane) enters the first air bag 2 on the driving pipeline 1 to store compressed gas in advance, and the compressed gas enters the first pipeline 4 through one outlet of the tee 3 and then enters the output pipe 7, and enters the second pipeline 5 through another outlet of the tee 3, and then enters the second air bag 6 to compress the gas. Finally, the fire extinguishing agents in the first pipeline 4 and the second pipeline 5 enter the output pipe 7 in parallel and are finally output. That is, the output pipe 7 is supplied with gas through two pipelines. Compared with when only the driving pipeline 1 supplies gas to the output pipe 7, the gas in the two pipelines is more than the gas in one driving pipeline 1. During maintenance, the output pipe 7 can be supplied with gas for a period of time, which is convenient for the output pipe 7 to inspect or replace the fire extinguishing tank without stopping the gas supply, and does not affect the fire extinguishing efficiency.

[0026] The output pipe 7 is provided with an electronic alarm 8, which is integrated with a pressure sensor, and the signal output end of the electronic alarm 8 is connected to the control box 11. The electronic alarm 8 is integrated with a pressure sensor, and when the pressure sensor senses that the gas leakage pressure in the output pipe 7 is reduced, a signal is sent to the electronic alarm 8, which will alarm.

[0027] Reference Figure 3 In this embodiment, the inner walls of the driving pipeline 1 and the output pipe 7 are both provided with a sound-absorbing layer 10. The material of the sound-absorbing layer 10 is preferably sound-absorbing cotton, which can effectively eliminate the noise of the fire extinguishing agent flowing in the driving pipeline 1 and the output pipe 7, so that in the silent state, the alarm sound of the electronic alarm 8 can effectively warn.

[0028] Example 2

[0029] Reference Figure 1 and Figure 2 An automatic shut-off valve 9 capable of automatic shut-off is installed on the driving pipeline 1. The outer wall of the automatic shut-off valve 9 and the driving pipeline 1 are fully welded. A blocking block 14 and a control box 11 are arranged in the automatic shut-off valve 9. A connecting rod 15 is symmetrically embedded at the bottom of the blocking block 14. The bottom of the connecting rod 15 is connected to the bottom of the automatic shut-off valve 9 through a spring 16.

[0030] Furthermore, an electromagnet 13 is provided at the top of the automatic shut-off valve 9 , an iron block 12 connected to the electromagnet 13 is provided on the blocking block 14 , and the electromagnet 13 is electrically connected to the control box 11 .

[0031] Furthermore, a limiting top column 17 is symmetrically arranged at the bottom of the automatic shut-off valve 9 , and the limiting top column 17 is located outside the spring 16 .

[0032] Specifically, during use, after the electronic alarm 8 sounds an alarm, the staff sends a work instruction to the control box 11 by operating the remote control. After receiving the instruction, the control box 11 immediately drives the electromagnet 13 to stop energizing. At this time, the electromagnet 13 loses its magnetism and is separated from the iron block 12. At this time, the blocking block 14 moves downward rapidly under the action of the spring 16 until the bottom of the blocking block 14 abuts against the limiting top column 17, forming the drive pipeline 1 in a blocked and separated state, which can quickly realize the blocking work of the drive pipeline 1 and avoid the waste of resources caused by continuous leakage of the fire extinguishing agent.

[0033] To sum up, when the driving pipeline 1 of the fire extinguisher leaks, the utility model can give an alarm through the electronic alarm 8 on the output pipe, and the blocking block 14 in the automatic shut-off valve 9 on the driving pipeline 1 quickly forms a blocked and separated state for the driving pipeline 1, and can quickly achieve the blocking work of the driving pipeline 1 to avoid continuous leakage of the fire extinguishing agent and cause waste of resources.

[0034] Furthermore, the utility model can ensure that after the driving pipeline 1 stops supplying gas, the output pipe 7 continues to supply gas for a period of time through the arrangement of the first pipeline 4 and the second pipeline 5, so as to facilitate the inspection or replacement of the fire extinguishing tank without stopping the gas supply and not affecting the fire extinguishing efficiency.

[0035] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.

[0036] The above description is only a preferred implementation mode of the present utility model. Any technical solution that achieves the purpose of the present utility model by basically the same means belongs to the protection scope of the present utility model.
