Please refer to Figures 1 and 2. Figure 1 illustrates a three-dimensional schematic diagram of a fire drainage system 1000 according to an embodiment of the present invention. Figure 2 illustrates an explosion of the fire drainage system 1000 according to the embodiment of Figure 1. Schematic diagram. As shown in Figures 1 and 2, the fire drainage system 1000 includes a fire pipeline 1100, a sprinkler 1200 and a drainage device 1300. The fire pipe 1100 is used to detachably connect a water delivery device. The sprinkler 1200 is detachably connected to the fire pipeline 1100 and includes a sprinkler port 1210 and a sprinkler sensing element 1220 . The sprinkler port 1210 is connected to the fire pipeline 1100. The sprinkler sensing element 1220 is used to open and close the sprinkler outlet 1210 and includes a pipe body 1221. The drainage device 1300 includes a housing 1310 and a breaking component 1320. The housing 1310 includes an internal space 1311 (marked in Figure 3), an interface 1312 and a breach 1313. The interface 1312 allows the sprinkler 1200 to be inserted into the interior space 1311 . The breach 1313 is connected to the internal space 1311. The breaking component 1320 is detachably disposed on the housing 1310 and includes a breaking rod 1321, and the breaking rod 1321 corresponds to the breaking opening 1313. Among them, when the breaking rod 1321 is driven by an external force, moves toward the pipe body 1221 in the internal space 1311 and breaks the pipe body 1221, the sprinkler port 1210 is opened, allowing a fluid F (shown in Figure 5) to flow from the fire pipeline 1100 and sprinkle water. The container 1200 flows to the interior space 1311 of the housing 1310.

The fire pipeline 1100 can be detachably connected to a water delivery device that accommodates high-pressure fluid F through a water delivery valve. When a user wants to replace the fire drainage system 1000, the user can first remove the water delivery device. The water delivery valve connected to the firefighting pipeline 1100 is closed. At this time, fluid F may remain in the firefighting pipeline 1100 . Then, the user can install the drainage device 1300 on the sprinkler 1200, and drive the breaking rod 1321 to move in the internal space 1311 and break the pipe body 1221, so that the sprinkler port 1210 is opened, so that the fluid F remaining in the fire pipeline 1100 can flow out. to the internal space 1311 to drain the fluid F in the firefighting pipeline 1100. This can avoid the possibility of accidental spraying out of the fluid F during the disassembly process because the fire pipe 1100 still has fluid F that has not been discharged, and can ensure that the equipment adjacent to the fire pipe 1100 will not get wet or damp during the replacement operation, and There is no need to move adjacent equipment to another space, thereby improving the safety and smoothness of replacement operations. The structural details of the fire drainage system 1000 will be described in detail below.

In this embodiment, the structure of the sprinkler 1200 can be a common automatic sprinkler in this technical field. The sprinkler sensing element 1220 can include a sealing member to close the sprinkler port 1210 to prevent the fluid F from being discharged from the sprinkler port 1210 . The tube body 1221 resists the sealing member, and the tube body 1221 can be a glass tube or a fragile metal tube, which will be heated and broken under high temperature. When the pipe body 1221 ruptures, the closure loses support and detaches from the sprinkling port 1210 to allow the fluid F to be discharged from the sprinkling port 1210 .

The drain port 1314 is connected to the internal space 1311, and the two control valves 1315 are connected to the breach port 1313 and the drain port 1314 respectively and are used to open and close the breach port 1313 and the drain port 1314 respectively. Specifically, the interface 1312 is located above the internal space 1311, and the breach opening 1313 and the drain outlet 1314 are located on both sides of the internal space 1311 respectively, so that the overall shape of the housing 1310 is generally a cross shape, but the present invention is not limited to this. . When the control valve 1315 opens the drain port 1314, the fluid F can flow from the internal space 1311 to the drain port 1314, and be discharged from the drain port 1314 outside the housing 1310. Furthermore, the drain port 1314 can be connected to a drain line, thereby guiding the fluid F through the drain line to a drain location for discharge. In this way, the problem of accidentally spraying the fluid F onto adjacent equipment during the process of emptying the equipment, causing damage to the equipment, can be further avoided.

The drainage device 1300 may further include a water pressure detection element 1330. The water pressure detection element 1330 is connected to the drainage port 1314 and is used to detect a water pressure of the fluid F. The water pressure detection element 1330 can detect whether the water pressure of the fluid F flowing into the internal space 1311 is greater than a water pressure threshold. When the water delivery valve connected to the fire pipeline 1100 is not closed but is being replaced, the water pressure of the fluid F in the internal space 1311 is greater than the water pressure threshold, so the user can detect the water through the water pressure detection element 1330 Pressure learned that the fire pipeline 1100 did not close the water delivery valve as scheduled. The user can first close the control valve 1315 to prevent the fluid F from continuing to be discharged outside the housing 1310, and then check to confirm whether the fire pipeline 1100 is a pipeline scheduled to be drained and replaced; when the user confirms that the fire pipeline 1100 does not need to be drained pipeline, the user can disassemble the drainage device 1300 and the sprinkler 1200 from the fire pipeline 1100, and install another new sprinkler on the fire pipeline 1100; when the user confirms that the fire pipeline 1100 is the pipeline scheduled to be drained, but The water delivery valve is not closed correctly, and the user can continue the drainage operation after closing the water delivery valve. Furthermore, through the configuration of the water pressure detection element 1330, it is possible to avoid the possibility that the water pressure of the fluid F in the internal space 1311 is too high and exceeds the pressure resistance of the housing 1310, thereby damaging the housing 1310. This can further improve the accuracy and stability of replacement operations.

Figure 3 illustrates a partially cutaway schematic diagram of the fire drainage system 1000 according to the embodiment of Figure 1, and Figure 4 illustrates a fire drainage system 1000 according to the embodiment of Figure 3. A schematic diagram of the rupture rod 1321 rupturing the tube body 1221. Figure 5 shows a schematic diagram of the fluid F being discharged from the drain port 1323 according to the embodiment of Figure 3. As shown in Figures 2 to 5, the breaking component 1320 may further include a fixed pipe 1322 and a drain valve 1324. The fixed pipe 1322 is connected to the breaching opening 1313 and has a drain port 1323. The breaching rod 1321 is slidably inserted into the fixed pipe 1322. One end of the breaching rod 1321 protrudes from the fixed pipe 1322 in a direction away from the breaching opening 1313. The breaching rod 1321 The other end is used to move toward the tube body 1221 from the breaching hole 1313 to break the tube body 1221. The drain valve 1324 is connected to the drain port 1323 and used to open and close the drain port 1323 to allow the fluid F to be discharged from the drain port 1323. When the sprinkler 1200 is inserted into the housing 1310, the control valve 1315 corresponding to the breaching port 1313 can be opened or has been opened in advance, so that the user can push the one end of the breaching rod 1321 to drive the other end of the breaching rod 1321 into the interior. space 1311 to break the tube body 1221, and the user can pull the aforementioned end of the breaking rod 1321 to return to an initial position and rotate the drain valve 1324 to open the drain port 1323, so that the fluid F can flow through the fixed pipe 1322 from the breaching port 1313, And discharged from the drain port 1323 to the housing 1310 .

In this embodiment, the aperture of the drain port 1323 can be smaller than the aperture of the breach port 1313 and the drain port 1314, and a sealing member is provided at the position where the water pressure detection element 1330 is connected to the drain port 1314 to prevent the fluid F from being discharged from the drain port 1314. . In this way, the fluid F is only allowed to be discharged from the small-diameter drain port 1323, which is convenient for the user to first drain a small amount through the drain port 1323, and detect the water pressure of the fluid F through the water pressure detection element 1330, so as to avoid making mistakes. In the case of drainage operation, a large amount of fluid F is discharged from the drainage port 1314.

When the sprinkler 1200 is inserted into the housing 1310, the first frame 1230 is connected to the second frame 1316 in a screw connection, so that the position of the pipe body 1221 in the internal space 1311 corresponds to the breaching opening 1313. Through the configuration of the first frame 1230 and the second frame 1316, the tube body 1221 can be aligned with the breaching opening 1313, and when the breaching rod 1321 moves toward the tube body 1221 in the internal space 1311, it can accurately contact and breach the tube body 1221, and thus Improve the stability of drainage of the drainage device 1300. Furthermore, the fire drainage system 1000 may further include a third frame 1400, which is connected to the first frame 1230 and connected to the ceiling of a room, thereby fixing the sprinkler 1200 on the ceiling. Furthermore, the third frame 1400 can be screwed to the top of the first frame 1230 with two screws, and the second frame 1316 can then be screwed to the bottom of the first frame 1230 with the same screws, so that the drainage device 1300 is installed. The sprinkler 1200 is located on the ceiling, but the present invention is not limited to this.

In other embodiments, when the sprinkler is inserted into the housing, the breaking component can be disassembled first, and the user can observe the position of the pipe body in the internal space through the breaking hole, and move the housing to align the position of the pipe body with the breaking hole. , and then fix the shell to the sprinkler to locate the position of the pipe body, but the present invention is not limited to the above method.

In other embodiments, the sprinkler may further include a closed ring that is sleeved on the sprinkler and used to resist the interface. When the sprinkler is inserted into the housing from the interface, the closing ring can seal the interface, making the internal space an airtight space to ensure that high-pressure fluid does not leak from the interface, thus preventing the possibility of fluid spraying into the equipment.

Please refer to Figure 6, which illustrates a step block diagram of a fire drainage method S100 according to another embodiment of the present invention. The following fire drainage method S100 will be described in conjunction with the fire drainage system 1000 of the embodiment in Figures 1 to 5, but the present invention is not limited thereto. As shown in Figure 6, the fire drainage method S100 is used to drain a fluid F located in a fire pipeline 1100. The fire pipeline 1100 is detachably connected to a water delivery device and connected to a sprinkler 1200. The fire drainage method S100 includes an installation step S110, a drainage step S120 and a replacement step S140. In the installation step S110, a housing 1310 of a drainage device 1300 is installed on the sprinkler 1200, so that the sprinkler 1200 is inserted into an internal space 1311 of the housing 1310. In the drainage step S120, a breaking rod 1321 of the drainage device 1300 is driven, so that the breaking rod 1321 moves toward the sprinkler 1200 in the internal space 1311 and touches the sprinkler 1200. A sprinkling port 1210 of the sprinkler 1200 is opened to allow the fluid to flow. F flows from the fire pipe 1100 and the sprinkler 1200 to the internal space 1311 of the housing 1310. In the replacement step S140, after the fluid F is completely discharged from the sprinkler port 1210 to the firefighting pipeline 1100, the firefighting pipeline 1100 is removed from the water delivery device.

This ensures that the fluid F in the fire protection pipeline 1100 can be completely drained, and avoids the possibility that the fluid F remaining in the fire protection pipeline 1100 may accidentally spray adjacent equipment due to the replacement of the fire protection pipeline 1100, causing damage to the equipment.

Furthermore, in the drainage step S120, the breaking rod 1321 can contact and break a pipe body 1221 of the sprinkler 1200, so that the sprinkler port 1210 through the pipe body 1221 is opened to allow the fluid F to flow to the internal space 1311. In other embodiments, the breaking rod can contact the sprinkler sensing element of the sprinkler without breaking any element, and the sprinkler opening is opened after the sprinkler sensing element is stressed. The present invention is not limited to the above method.

In the draining step S120 , the fluid F can be discharged outside the housing 1310 to prevent the water volume of the fluid F from being greater than the capacity of the internal space 1311 . Furthermore, the fluid F can be discharged from the housing 1310 through the breach 1313 or the drain port 1314, but the invention is not limited thereto.

The fire drainage method S100 may further include a water pressure detection step S130, which detects a water pressure of the fluid F in the internal space 1311 through a water pressure detection element 1330. When the water pressure of the fluid F is greater than a water pressure threshold, the fluid is blocked. F is discharged outside the housing 1310. In this way, it is possible to confirm whether the water delivery valve connected to the firefighting pipeline 1100 is closed by detecting water pressure, so as to facilitate the user to confirm whether the drainage operation can be continued or the operation can be stopped and inspected.

To sum up, this new model has the following advantages: first, by breaking the pipe body with the breaking rod, the fluid in the fire pipeline can be ensured to be emptied, thereby improving the safety of the replacement operation; second, by detecting the water pressure through the water pressure detection element The water pressure of the fluid can confirm whether the water delivery valve connected to the fire pipeline is closed to improve the accuracy of the replacement operation; and thirdly, through the configuration of the first frame and the second frame, the position of the pipe body can be aligned to break the mouth to improve the accuracy of the breaker rod breaking through the pipe body.
