[0025] See also Figure 1 The present invention provides a fire protection system 100, which is used in an indoor space, and includes: a first joint 1, a second joint 2, a pipeline system 3 and a plurality of fire sprinklers 4; the first joint 1 is used to connect to a gas fire extinguisher; the second joint 2 is used to connect to a water-based fire extinguisher; a medicine channel is formed in the pipeline system 3, the pipeline system 3 has a liquid inlet end and a liquid outlet end, the first joint 1 and the second joint 2 are connected to the liquid inlet end, a temperature control valve 31 is arranged in the medicine channel, and the temperature control valve 31 is used to control the opening or closing of the medicine channel according to the temperature; the plurality of fire sprinklers 4 are connected to the liquid outlet end to spray water-based fire-fighting liquid or gas fire-fighting liquid outward; wherein the plurality of fire sprinklers 4 are used to spray at different positions respectively, and at the same time, the temperature control valve opens at high temperature and automatically closes at low temperature, and can realize automatic opening and closing.

[0026] The present invention provides a fire fighting system 100, which includes two types of connectors, wherein the first connector 1 is connected to a gas fire extinguisher, and the second connector 2 is connected to a water-based fire extinguisher. The first connector 1 and the second connector 2 are both connected to the liquid inlet end of the pipeline system, and a plurality of fire sprinklers 4 are connected to the liquid outlet end. When a fire occurs, the temperature control valve 31 senses the high temperature generated indoors and automatically opens the agent channel. At this time, according to actual needs, the first connector 1 or the second connector 2 can be selected to be connected, and then water-based fire fighting liquid or gas fire fighting liquid can be selected to be sprayed to produce different fire fighting effects, thereby ensuring the effectiveness of fire extinguishing and the safety of personnel.

[0027] It should be noted that the first connector 1 and the second connector 2 are respectively connected to different pressure systems, and the pressure values ​​therebetween are different. In order to avoid mixing of the two, a switch system may be provided corresponding to the first connector 1 and the second connector 2 respectively.

[0028] Furthermore, a switch valve 5 is provided between the second connector 2 and the liquid inlet end; the first connector 1 is connected to the switch valve 5 and the liquid inlet end. In this embodiment, the switch valve 5 can be used to control the second connector 2 to be connected to the pipeline system. During use, the water-based fire extinguisher connected to the second connector 2 can be kept closed, thereby ensuring that the fire-fighting equipment connected to the first connector 1 is in a normally open state. Under the action of pressure, the fire-fighting gas in the first connector 1 can directly enter the pipeline system. When a fire occurs, the fire-fighting liquid can be sprayed directly without the need to open the pipe again. Improve the response speed.

[0029] Furthermore, in this embodiment, the fire protection system 100 also includes a one-way valve 6, which is arranged between the switch valve 5 and the liquid inlet end; the first connector 1 is connected to the one-way valve 6 and the liquid inlet end. In this embodiment, since the pressure in a general gas fire-fighting device is greater than the pressure in a water-based fire-extinguishing system, the one-way valve allows the second joint 2 to only transport water-based fire-extinguishing liquid into the agent channel, and the gas in the agent channel will not flow back into the second joint 2. Therefore, the water-based fire extinguisher connected at the second joint 2 can be kept in a normally open state, and the gas will not reversely enter the water-based fire extinguisher. During use, as long as the temperature control switch 31 is turned on, the fire-fighting gas in the first joint 2 will directly flow into the pipeline system under the action of pressure and spray outward through the fire-fighting nozzle 4. Due to the existence of pressure, the second joint 2 will be forced to be unable to transport water-based fire-fighting liquid into the pipeline system. After the fire-fighting liquid in the fire-fighting device connected at the first joint 1 is used up, the pressure value in the pipeline system decreases. At this time, the second joint 2 allows the tap water in the household water pipe system to continue to spray outward from the fire-fighting nozzle 4, thereby maintaining the continuous spraying of the fire-fighting nozzle 4 without manual operation.

[0030] Furthermore, a second one-way valve is provided between the second connector and the liquid inlet end to prevent the water-based fire-fighting liquid from entering the first connector.

[0031] In addition, the fire protection system 100 further includes a pressure alarm 7, which is arranged in the agent channel and between the temperature control valve 31 and the liquid inlet end, for detecting the liquid pressure in the agent channel. In this embodiment, once the temperature control valve 31 is opened, the pressure value in the agent channel will change dramatically. Since the fire protection equipment connected to the first joint 1 is in a normally open state during the initial process, the agent channel between the temperature control valve 31 and the liquid inlet end is kept in a high pressure state. After the temperature control valve 1 is opened, the pressure value decreases, triggering the alarm of the pressure alarm 7, so that personnel can discover and deal with the fire in time, and can also remind personnel to take refuge, and subsequently replace and replenish the water-based fire extinguisher and the gas fire extinguisher to maintain the liquid pressure in the agent channel for reuse.

[0032] It should be noted that there are multiple implementations of the pressure alarm 7, such as using a pressure sound and light alarm to remind people through sound and light at the same time.

[0033] On the other hand, the fire fighting system 100 further includes an active switch 8, which is connected to the temperature control valve and is used to drive the temperature control valve to open the medicine passage. In this embodiment, since the fire fighting system 100 is mainly arranged in an indoor space, when a small-scale fire occurs, the fire fighting system 100 will not react in time. By setting the active switch 8, personnel can actively open the fire sprinkler 4 to protect personnel.

[0034] On the other hand, the fire fighting system 100 further comprises a water-based fire extinguisher and a gas fire extinguisher, wherein the water-based fire extinguisher and the gas fire extinguisher are connected to the first connector and the second connector, respectively. In this embodiment, a complete fire fighting system is formed by the water-based fire extinguisher and the gas fire extinguisher.

[0035] It should be noted that the first connector 1 can be provided in plurality, and the gas fire extinguisher can be provided in plurality accordingly, so as to ensure the amount of fire-fighting fluid; or, the gas fire extinguisher can be provided in plurality and connected to the first connector 1 through a multi-way valve, and no specific limitation is made here.

[0036] Similarly, the second connector 2 may be provided with multiple, and the water-based fire extinguisher may be provided with multiple corresponding; or, the water-based fire extinguisher may be provided with multiple, and connected to the second connector 2 through a multi-way valve, without specific limitation here.

[0037] At the same time, there is no specific restriction on the number of fire sprinklers, which can be adaptively set according to the size of the space and are not specifically limited here.

[0038] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
