Description

Technical Field

[0001] This utility model relates to the field of thermal aerosol fire extinguisher technology, specifically a silent terminal installation device for thermal aerosol fire extinguishers. Background Technology

[0002] Gaseous fire suppression systems are one of the four traditional fixed fire suppression systems (water, gas, foam, and dry powder). They consist of a gas extinguishing device (or component) and an alarm control system. Thermal aerosol automatic fire suppression devices can be divided into thermal aerosols and cold aerosols based on the method of aerosol generation. Aerosol fire suppression devices used in domestic engineering projects are all thermal types; cold aerosol fire suppression technology is still in the research and development stage, with no formal products yet. Thermal aerosols extinguish fires based on principles such as negative catalysis and disrupting the combustion reaction chain.

[0003] Thermal aerosol fire extinguishers are mainly operated automatically through control equipment during use. Therefore, they need to be connected to the control equipment via wiring terminals. However, the wiring terminals of existing thermal aerosol fire extinguishers are susceptible to electromagnetic interference after wiring, which can generate noise and affect the stability of signal transmission. In addition, the gas jet of thermal aerosol fire extinguishers can be unstable during use, which can easily cause the wiring terminals to loosen. Therefore, improvements are needed.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7This utility model provides a technical solution: a silent terminal installation device for a thermal aerosol fire extinguisher, including a thermal aerosol fire extinguisher body 3, a base 2 at the bottom of the thermal aerosol fire extinguisher body 3, an opening on one side of the base 2, and a drawer box 1 inserted inside the opening. A counterweight 20 is placed inside the drawer box 1. This drawer box 1 allows for easy addition or removal of the counterweight 20. Increasing the counterweight 20 increases the weight of the base 2, thereby making the bottom of the thermal aerosol fire extinguisher body 3 more stable. This prevents mechanical vibration and instability caused by gas diffusion during the thermal aerosol fire extinguisher body 3, thus improving the stability of the thermal aerosol fire extinguisher body 3 and preventing the terminal cable 8 from being pulled. The fire extinguisher body 3 has a wiring port 4 on one side, through which a terminal cable 8 is connected. A bracket 6 is fixedly connected to one side of the base 2. One side of the bracket 6 has an opening, while the other side is open. Multiple sets of sliding grooves are provided on the inner wall of the open side of the bracket 6. A limiting plate 7 is inserted inside each groove, forming a sliding connection with the bracket 6. The limiting plate 7 is fitted against one side of the terminal cable 8. This structure allows for easy adjustment of the limiting plate 7's position through its sliding connection with the bracket 6. The limiting plate 7 can limit one side of the terminal cable 8, keeping it in place and preventing it from being pulled. The lower end of the terminal cable 8 can be fixed to the ground using plastic clips, improving its position. For stability, one end of the terminal cable 8 passes through the bracket 6 and is fixed to the ground. A plastic corrugated tube 14 is movably connected between the bracket 6 and the wiring port 4. The outer wall of the plastic corrugated tube 14 is provided with a waterproof layer 5. A connecting block 13 is fixedly connected to one side of the plastic corrugated tube 14. The connecting block 13 has a ring structure. A plug block 12 is fixedly connected to one side of the connecting block 13. A support spring 10 is fixedly connected to the top of the plug block 12. A locking block 9 is connected to the top of the support spring 10. The waterproof layer 5 of this structure is waterproof paint, which can improve the waterproof performance of the plastic corrugated tube 14. A connecting seat 11 is fixedly connected to one side of the wiring port 4. A slot is opened on one side of the connecting seat 11. A through hole is opened at the top of the slot. The plug block 12 is inserted into the slot, and the locking block 9 is inserted into the through hole. This structure is designed to improve stability. The insert block 12, the locking block 9, and the support spring 10 can fix the connecting block 13 to the connecting seat 11. The support spring 10 can support the locking block 9, and when the locking block 9 is pressed, it can be retracted into the connecting seat 11, thus facilitating the connection and separation of the insert block 12 and the connecting seat 11. The inner wall of the plastic corrugated tube 14 is provided with an electromagnetic shielding layer 15. The outer wall of the terminal cable 8 is fitted with an upper support block 16 and a lower support block 18. Both the upper support block 16 and the lower support block 18 have a "U" shaped structure when viewed from the side. The two ends of the upper support block 16 are connected to sleeves 19, and the sleeves 19 and the upper support block 16 are rotatably connected by a rotating shaft. This structure allows the sleeves 19 to rise and fall on the outer wall of the screw 17 by rotating the sleeves 19, thereby adjusting the height of the upper support block 16.The upper support block 16 rests on the inner wall of the plastic corrugated pipe 14 to prevent it from collapsing. Both ends of the lower support block 18 are fixedly connected to screws 17, the top of which is threaded into a sleeve 19. The lower support block 18 is connected to the wiring port 4 and the bracket 6 via support rods. Support rods are inserted at both ends of the lower support block 18, which is slidably connected to them. The lower support block 18 can move laterally, allowing its position to be adjusted for easy adjustment of the support position of the plastic corrugated pipe 14. The sides of the support rods are fixedly connected to the outer walls of the wiring port 4 and the bracket 6. The upper support block 16 and the lower support block 18 are movably connected. The outer walls of the upper support block 16 and the lower support block 18 are fitted with plastic corrugated pipe 14. The electromagnetic shielding layer 15 enhances the electromagnetic shielding capability of the plastic corrugated pipe 14, preventing electromagnetic interference with the terminal cable 8.

[0026] Working principle: When using the silent terminal installation device for this thermal aerosol fire extinguisher, first connect one end of the terminal cable 8 to the wiring port 4, and then connect the other end of the terminal cable 8 through the connecting block 13, the upper support block 16, the lower support block 18, the plastic corrugated pipe 14, and the bracket 6 to the control equipment. Then adjust the height of the upper support block 16 by rotating the sleeve 19 to move it to a suitable height on the screw 17, so that the upper support block 16 is supported on the inner wall of the plastic corrugated pipe 14. Next, insert the plug 12 on one side of the connecting block 13 into the connecting seat 11 and press the locking block 9 on the top of the plug 12 so that the locking block 9 can smoothly enter the through hole inside the connecting seat 11. Finally, insert the limiting plate 7 into the sliding groove inside the bracket 6 to limit the terminal cable 8.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
