Description

Technical Field

[0001] The utility model relates to the technical field of temperature-sensing fire extinguishing, in particular to a prefabricated temperature-sensing fire extinguishing device. Background Art

[0002] A heat-sensing fire extinguishing device, also known as a tube-type automatic fire detection device, uses a heat detector to monitor ambient temperature changes in real time. Once a fire source is detected, it automatically initiates the fire extinguishing process, spraying fire extinguishing agent at the source to quickly extinguish the fire. It primarily consists of a fire extinguishing agent cylinder assembly, a fire detection tube, and a signal feedback device. The fire detection tube, serving as a fire alarm, can be conveniently placed near every potential fire point.

[0003] The Chinese patent with authorization announcement number CN218187594U discloses an indirect fire detection tube fire extinguishing device. When a fire occurs and the fire is small, the emitted smoke is transmitted to the smoke sensor. At the same time, the control module cuts off the power to the electromagnet. The electromagnet no longer adsorbs the iron plate. The iron plate drives the puncture knife to puncture the fire detection tube, thereby causing the pressure inside the fire detection tube to drop, activating the bottle head control valve, and the fire extinguishing medium passes through the release tube to the nozzle, and then sprays into the protected area to achieve the purpose of automatic fire extinguishing.

[0004] However, the fire extinguishing device mentioned above requires the addition of a control circuit connected to the electromagnet and smoke sensor. The introduction of the control circuit makes the structure and operation process of the entire fire extinguishing device more complicated, which not only increases the difficulty of installation and debugging, but also increases the complexity of subsequent maintenance and troubleshooting. Utility Model Content

[0005] In response to the problems existing in the background technology, a prefabricated temperature-sensing fire extinguishing device is proposed. While not requiring additional control circuits, it achieves the purpose of rapid and automatic fire extinguishing, simplifying the troubleshooting and debugging process.

[0006] The utility model proposes a prefabricated temperature-sensing fire extinguishing device, comprising

[0007] The storage bottle is provided with a bottle head control valve, the side and top of the bottle head control valve are provided with joints, both sets of joints are provided with a fire detection tube and a release tube, and a nozzle is provided at one end of the release tube;

[0008] A protection assembly, mounted on the joint, for protecting the fire detection tube and the release tube from breaking at the joint; and

[0009] The quick puncture component is arranged on the fire detection tube and is used for puncturing the fire detection tube.

[0010] Preferably, the fire detection tube is provided with a plurality of groups of evenly distributed magnetic blocks, which are used to fix the fire detection tube at a desired position in the supervision area.

[0011] Preferably, the protective part includes a hexagonal nut, a protective tube and a protective spring. The hexagonal nut is connected to the outside of the joint, and its side end face is provided with a protective tube located outside the release tube. One end of the protective tube is connected to a protective spring, and the protective spring is sleeved on the outside of the release tube.

[0012] Preferably, the outer wall of the joint is provided with an external thread for threaded connection with a hexagonal nut.

[0013] Preferably, the quick puncture assembly includes a box body, a slide, a support spring, a cutter and a connecting piece. The box body is arranged on the outside of the fire detection tube, and connecting holes for the fire detection tube to pass through are symmetrically opened on both sides of the box body. A slide is slidably connected to the inside of the box body, a support spring is provided at the bottom of the slide, a cutter is provided on the top of the slide that is opposite to the fire detection tube, and a connecting piece for limiting it is provided on the outside of the slide.

[0014] Preferably, the connecting member includes a connecting column, a hanging rope and a clamping column, the box body is provided with a through slot facing the slide, the slide is connected to a connecting column passing through the through slot, and the hanging rope is provided on the connecting column;

[0015] The clamping column is set to be T-shaped, one end of its vertical section is connected to the outer wall of the box body, and the bottom end of the hanging rope is clamped between its vertical section and horizontal section.

With the cooperation of the box body, the slide plate, the support spring, the cutter, the connecting column, the hanging rope and the clamping column, when the fire is small and burns to the hanging rope, the hanging rope breaks. At this time, the slide plate loses its limiting force and moves upward under the action of the support spring, so that the cutter on its top punctures the fire detection tube, causing the pressure inside the fire detection tube to drop, starting the bottle head control valve, and the fire extinguishing medium passes through the release tube to the nozzle, and then sprays into the protected area, thereby achieving the purpose of automatic fire extinguishing. There is no need to add a control circuit as a whole, which simplifies the overall operation process and subsequent maintenance steps.

[0023] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0024] Example 1

[0025] like Figure 1-Figure 4 As shown, the utility model proposes a prefabricated temperature-sensing fire extinguishing device, including a storage bottle 1, a protective component and a quick puncture component. A bottle head control valve 2 is provided on the storage bottle 1, and joints 3 are provided on the side and top of the bottle head control valve 2. Fire detection tubes 4 and release tubes 5 are provided on the two groups of joints 3. A nozzle 20 is provided at one end of the release tube 5. A protective component is assembled on the joint 3, which is used to prevent the fire detection tube 4 and the release tube 5 from breaking from the joint 3. Multiple groups of quick puncture components are evenly distributed on the fire detection tube 4, which are used to puncture the fire detection tube 4.

[0026] like Figure 2 As shown, the fire detection tube 4 is provided with a plurality of groups of evenly distributed magnetic blocks 6, which are used to fix the fire detection tube 4 at the required position in the supervision area.

[0027] like Figure 4 As shown, the protective part includes a hexagonal nut 7, a protective tube 8 and a protective spring 9. The hexagonal nut 7 is connected to the outside of the joint 3, and its side end face is provided with a protective tube 8 located outside the release tube 5. One end of the protective tube 8 is connected to the protective spring 9, and the protective spring 9 is sleeved on the outside of the release tube 5.

[0028] like Figure 4 As shown, the outer wall of the connector 3 is provided with an external thread 10 for threaded connection with the hexagonal nut 7 .

[0029] When connecting the fire detection tube 4 or the release tube 5, first put the protective spring 9, protective tube 8 and hexagonal nut 7 on one end of the tube body. Then, after the fire detection tube 4 and the release tube 5 are connected, screw on the hexagonal nut 7 so that the hexagonal nut 7 is screwed into the joint 3 to complete the installation of the protective component. After the installation is completed, the protective tube 8 and protective spring 9 can make the spring absorb and disperse the forces when the fire detection tube 4 is squeezed or twisted by external forces, effectively preventing the fire detection tube 4 from twisting or deforming. The protective tube 8 can reduce the direct contact of the fire detection tube 4 with the surrounding environment, thereby reducing the risk of wear and damage caused by friction.

[0030] Example 2

[0031] like Figure 1-Figure 4 As shown, the present invention proposes a prefabricated temperature-sensing fire extinguishing device. Based on the above embodiment, this embodiment also records in detail the specific components of the rapid puncture assembly and the puncture method of the fire detection tube 4.

[0032] like Figure 3 As shown, the quick puncture assembly includes a box body 11, a slide 12, a support spring 13, a cutter 14 and a connecting piece. The box body 11 is arranged on the outside of the fire detection tube 4, and connecting holes 15 for the fire detection tube 4 to pass through are symmetrically opened on both sides of the box body 11. The slide 12 is slidably connected to the inside of the box body, and a support spring 13 is provided at the bottom of the slide 12. A cutter 14 facing the fire detection tube 4 is provided on the top of the slide 12, and a connecting piece for limiting it is provided on the outside of the slide 12.

[0033] like Figure 3 As shown, the connecting part includes a connecting column 16, a hanging rope 17 and a clamping column 18. A through slot 19 facing the slide 12 is opened on the box body 11, and the slide 12 is connected to the connecting column 16 passing through the through slot 19, and the hanging rope 17 is provided on the connecting column 16; the clamping column 18 is set to be T-shaped, and one end of its vertical section is connected to the outer wall of the box body 11, and the bottom end of the hanging rope 17 is clamped between its vertical section and horizontal section.

[0034] During use, the connecting column 16 and the slide 12 are limited by the engagement of the hanging rope 17 and the card column 18, so that the slide 12 squeezes the support spring 13, driving the cutter 14 to be located below the fire detection tube 4, and the hanging rope 17 is exposed. When the fire burns to the hanging rope 17, the hanging rope 17 breaks. At this time, the slide 12 loses its limiting force and moves upward under the action of the support spring 13, so that the cutter 14 at its top punctures the fire detection tube 4, causing the pressure inside the fire detection tube 4 to drop, starting the bottle head control valve 2, and the fire extinguishing medium passes through the release pipe 5 to the nozzle 20, and then sprays into the protected area, achieving the purpose of automatic fire extinguishing.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
