Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide fire extinguishing, and in particular to a high-pressure nozzle for a carbon dioxide fire extinguishing system. Background Technology

[0002] In the field of fire safety, carbon dioxide fire extinguishing systems are widely used in fire suppression operations in special scenarios such as electrical fires and precision instrument fires due to their high efficiency, residue-free operation, and non-conductive properties. High-pressure nozzles, as the core component of carbon dioxide fire extinguishing systems, directly affect the fire suppression effect and efficiency. Currently, most high-pressure nozzles in carbon dioxide fire extinguishing systems are fixed designs, and their spray range is limited by the installation position and angle of the nozzle, making it difficult to effectively cover large or complex spaces, resulting in low fire suppression efficiency. Furthermore, when not in use, the nozzle's outlet is directly exposed to the external environment, making it susceptible to the intrusion of dust, debris, and other contaminants, leading to nozzle blockage and affecting the reliability and safety of subsequent use. Long-term exposure may also accelerate the corrosion and aging of the internal materials of the nozzle, shortening the equipment's lifespan.

[0003] Therefore, it is necessary to design a high-pressure nozzle for a carbon dioxide fire extinguishing system that can automatically rotate the nozzle to uniformly spray carbon dioxide for fire extinguishing, while simultaneously rotating the cover to close the nozzle after use to protect the outlet of the nozzle, expand the coverage area, prevent nozzle blockage and contamination, and improve the fire extinguishing effect and efficiency. Utility Model Content

[0004] To overcome the shortcomings of high-pressure nozzles, which are mostly designed to be fixed, limiting their spray range to the installation position and angle, making it difficult to effectively cover large or complex spaces and resulting in low fire extinguishing efficiency, and whose outlets are directly exposed to the external environment, making them prone to clogging, this utility model provides a high-pressure nozzle for carbon dioxide fire extinguishing systems that can automatically drive the nozzle to rotate and evenly spray carbon dioxide for fire extinguishing. After use, the cover can be rotated to close and protect the outlet of the nozzle, expanding the coverage area, preventing nozzle clogging and contamination, and improving the fire extinguishing effect and efficiency.

[0005] Technical solution: A high-pressure nozzle for a carbon dioxide fire extinguishing system includes a feed pipe, a nozzle, a sleeve, a protective component, and an anti-clogging component. The nozzle is rotatably connected to the lower part of the feed pipe, and the sleeve is connected to the lower side of the nozzle. The sleeve is provided with a protective component for driving the nozzle to rotate and for protection. An anti-clogging component is provided on the inner side of the upper part of the feed pipe to prevent clogging.

[0006] In a preferred embodiment of this utility model, the protective component includes an impeller, a slide rod, a first telescopic spring, a shielding cover, and a protrusion. The slide rod is slidably connected to the sleeve and is slidably connected to the nozzle. An impeller is connected to the upper part of the slide rod. The first telescopic spring is connected between the sleeve and the slide rod. A shielding cover is rotatably connected to the upper part of the sleeve and is in contact with the nozzle. A protrusion is connected to the lower part of the shielding cover.

[0007] In a preferred embodiment of this utility model, a spiral groove is provided on the slide rod, and the slide rod and the protrusion are slidably connected through the spiral groove.

[0008] In a preferred embodiment of the present invention, multiple discharge ports are provided on both the nozzle and the shielding cover, and the discharge ports are evenly distributed along the nozzle and the shielding cover.

[0009] In a preferred embodiment of this utility model, the anti-clogging component includes an extrusion rod, rollers, a guide frame, a clearing rod, a second telescopic spring, and an extrusion frame. Multiple extrusion rods are slidably connected to the impeller, and rollers are rotatably connected to the lower part of each extrusion rod. The rollers are in contact with the impeller. A guide frame is connected to the lower inner side of the feed pipe, and a clearing rod is slidably connected to the guide frame. A second telescopic spring is connected between the clearing rod and the guide frame, and an extrusion frame is connected to the lower part of the clearing rod.

[0010] In a preferred embodiment of this utility model, the rollers are all made of rubber.

[0011] The present invention has the following advantages: 1. The present invention moves the impeller and slide bar to make the cover rotate, which in turn drives the nozzle to rotate and spray carbon dioxide evenly to extinguish the fire. Then, the cover rotates to close and protect the nozzle. Thus, the present invention can automatically drive the nozzle to rotate and spray carbon dioxide evenly to extinguish the fire. After use, the cover can be rotated to close and protect the outlet of the nozzle, expand the coverage area, prevent the nozzle from being blocked and contaminated, and improve the fire extinguishing effect and efficiency.

[0012] 2. This utility model, while the impeller rotates, also drives the extrusion rod to rotate and extrude the extrusion frame in sequence, causing the extrusion frame to move, causing the unblocking rod to move, causing the roller to rotate, thereby unblocking the feed pipe. This allows the feed pipe to be unblocked when carbon dioxide is sprayed for fire extinguishing, preventing particulate impurities generated in the system from clogging the nozzle and further improving the fire extinguishing efficiency.

Detailed Implementation

[0020] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] A high-pressure nozzle for a carbon dioxide fire extinguishing system, such as Figures 1-6 As shown, it includes a feed pipe 1, a nozzle 2, a sleeve 3, a protective component, and an anti-clogging component. The nozzle 2 is rotatably connected to the lower part of the feed pipe 1. The sleeve 3 is connected to the lower side of the nozzle 2. The sleeve 3 is provided with a protective component for driving the nozzle 2 to rotate and for protection. The upper inner side of the feed pipe 1 is provided with an anti-clogging component for preventing clogging.

[0022] like Figures 1-5As shown, the protective assembly includes an impeller 4, a slide rod 5, a first telescopic spring 6, a shielding cover 7, and a protrusion 8. The slide rod 5 is slidably connected to the sleeve 3, and the slide rod 5 is slidably connected to the nozzle 2. The impeller 4 is connected to the upper part of the slide rod 5. The first telescopic spring 6 is connected between the sleeve 3 and the slide rod 5. The shielding cover 7 is rotatably connected to the upper part of the sleeve 3. The shielding cover 7 is in contact with the nozzle 2. Both the nozzle 2 and the shielding cover 7 have six discharge ports, which are evenly distributed along the nozzle 2 and the shielding cover 7 to facilitate discharge. The protrusion 8 is connected to the lower part of the shielding cover 7. The slide rod 5 has a spiral groove, and the slide rod 5 and the protrusion 8 are slidably connected through the spiral groove.

[0023] like Figure 2 and Figure 6 As shown, the anti-clogging assembly includes a squeezing rod 9, a roller 10, a guide frame 11, a clearing rod 12, a second telescopic spring 13, and a squeezing frame 14. Four squeezing rods 9 are slidably connected to the impeller 4. The rollers 10 are rotatably connected to the lower part of each squeezing rod 9. The rollers 10 are all in contact with the impeller 4. The rollers 10 are all made of rubber and have good wear resistance. The guide frame 11 is connected to the lower inner side of the feed pipe 1. The clearing rod 12 is slidably connected to the guide frame 11. The second telescopic spring 13 is connected between the clearing rod 12 and the guide frame 11. The squeezing frame 14 is connected to the lower part of the clearing rod 12.

[0024] When a carbon dioxide fire extinguishing system is needed for fire suppression, this device can be used. Install this device on the discharge pipe of the carbon dioxide fire extinguishing system, then start the system. Carbon dioxide enters the nozzle 2, causing the impeller 4 to move along the extrusion rod 9 and the slide rod 5 to move along the sleeve 3. The first telescopic spring 6 is compressed, and under the action of the spiral groove, the shield 7 rotates and opens, aligning the discharge port on the shield 7 with the discharge port on the nozzle 2. This allows carbon dioxide to be sprayed evenly from the discharge port for fire suppression. Simultaneously, the impeller 4 rotates, driving the nozzle 2 to rotate along the feed pipe 1, causing the sleeve 3, slide rod 5, and shield 7 to rotate. This allows the nozzle 2 to rotate and spray carbon dioxide for fire suppression. While the impeller 4 rotates, it also drives the extrusion rod 9 to rotate, sequentially extruding the extrusion frame 14, causing the extrusion frame 14 to move. This causes the unblocking rod 12 to move along the guide frame 11. The second telescopic spring 13 is compressed, causing the roller 10 to rotate. The rollers 10 are all made of rubber and have good wear resistance. When the extrusion frame 14 disengages from the extrusion rod 9, the second telescopic spring 13 rebounds, and the unblocking rod 12 moves in the opposite direction to the extrusion frame 14 to reset, thereby unblocking the feed pipe 1. This allows the feed pipe 1 to be unblocked when carbon dioxide is sprayed for fire extinguishing, preventing particulate impurities generated in the system from clogging the nozzle 2 and improving the fire extinguishing efficiency. After the fire is extinguished, the fire extinguishing system is shut off, the first telescopic spring 6 rebounds, and the impeller 4 and the slide rod 5 move in the opposite direction to reset. Under the action of the spiral groove, the shielding cover 7 rotates in the opposite direction to reset and protect the outlet on the nozzle 2. This allows the nozzle 2 to rotate automatically and spray carbon dioxide evenly for fire extinguishing. After use, the shielding cover 7 is rotated to close and protect the outlet on the nozzle 2, expanding the coverage area, preventing the nozzle 2 from clogging and contaminating, and improving the fire extinguishing effect and efficiency.
