Description

Technical Field

[0001] This utility model belongs to the field of nozzle technology, specifically a fire cannon nozzle for multi-stage pressurized container ships. Background Technology

[0002] Fire monitor nozzles are key components of fire monitors, converting the pressure energy of fluids into kinetic energy and spraying it towards the fire source in jet form. Fire monitor nozzles can be classified into direct-flow and guide-flow types based on their structure. Direct-flow nozzles are simple in structure, easy to manufacture, have good jet focusing, long range, and stable performance, but their spray pattern is limited. Guide-flow nozzles can switch between direct-flow and spray modes or stabilize the range by adjusting the relative position of the nozzle core and the nozzle or the outlet area, offering diverse operational functions but with a complex structure and difficult manufacturing. Their applications are wide-ranging, including large-scale fires in industrial facilities, oil depots, and chemical plants; high-rise building fires; wildfires such as forest and grassland fires; and ship fires. They can spray large amounts of water mist and water flow onto the fire scene, effectively controlling and extinguishing the fire.

[0003] Existing fire monitor nozzles lack multi-stage pressurization capabilities, which can easily lead to insufficient range, making it difficult to cover distant fire sources. They also have weak penetration power, making them unable to cope with complex fire scene environments. Furthermore, they have low fire extinguishing efficiency and serious water waste. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a fire monitor nozzle for multi-stage pressurized container ships, which effectively solves the problems of existing fire monitor nozzles not having multi-stage pressurization capability, which easily leads to insufficient range, difficulty in covering long-distance fire sources, weak penetration, inability to cope with complex fire scene environments, low fire extinguishing efficiency, and serious waste of water resources.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire monitor nozzle for multi-stage pressurized container ships, comprising a main body, an inlet pipe fixedly installed at the bottom of the main body, a drive motor fixedly installed on one side of the main body, the output end of the drive motor extending into the interior of the main body and fixedly installed with an impeller, the side of the impeller away from the drive motor being rotatably connected to the inner wall of one side of the main body via a second shaft seat, a support plate fixedly installed on one side of the top of the main body, a protective cover fixedly installed on the upper part of one side of the support plate, a servo motor fixedly installed inside the protective cover, an installation shell fixedly installed on one side of the main body, a water outlet bucket fixedly installed in the middle of one side of the installation shell, four sealing baffles fixedly installed in a ring at equal intervals inside the installation shell, a transmission component provided at the output end of the servo motor, the transmission component being connected to the four sealing baffles in a transmission connection, when the servo motor is running, the power is output to the four sealing baffles through the transmission component, causing the four sealing baffles to rotate and adjust the opening and closing size.

[0006] Preferably, the transmission assembly includes a drive shaft, which is fixedly mounted on the output end of the servo motor. A positioning sleeve is rotatably mounted on the surface of the drive shaft. The surface of the positioning sleeve is fixedly connected to the middle of one end of the protective cover. One end of the drive shaft extends to the outside of the protective cover and is fixedly mounted with a transmission gear. A first bearing seat is rotatably mounted on the middle of one side of the transmission gear. A positioning seat is fixedly mounted on the end of the first bearing seat away from the drive shaft. The bottom of the positioning seat is fixedly connected to the top of the mounting shell.

[0007] Preferably, the top of the mounting housing has an opening in the middle, and the inner wall of the mounting housing has an annular groove. An inner and outer gear rings are slidably installed inside the annular groove. The transmission gear passes through the opening and enters the interior of the mounting housing, meshing with the upper part of the inner and outer gear rings.

[0008] Preferably, the inner wall of the inner and outer gear rings is circumferentially connected with four gear discs at equal intervals. One end of each of the four gear discs is fixedly connected to four sealing baffles, and one side of each of the four gear discs is rotatably connected to the inner wall of the mounting shell through a rotating seat.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, water enters the interior of the main body of the device through the water inlet pipe. At the same time, the operator starts the drive motor to drive the impeller to rotate along the second shaft seat. When the impeller rotates, it pressurizes the water through centrifugal force, thereby quickly throwing the water into the interior of the mounting shell. At the same time, the operator starts the servo motor to drive the drive shaft to rotate inside the positioning bushing. When the drive shaft rotates, it drives the transmission gear to rotate along the first shaft seat on the positioning seat.

[0010] When the transmission gear rotates, it drives the inner and outer gear rings to rotate inside the annular slide groove. When the inner and outer gear rings rotate, they drive the four sealing baffles to rotate and adjust the opening and closing size through the four gear discs, thereby increasing the water pressure by limiting the water flow. Then the water will be discharged through the outlet bucket. Because the outlet bucket is shaped like a bucket with a small diameter at the inlet end and a large diameter at the outlet end, the water pressure will be further increased when it is sprayed out. This gives the fire monitor nozzle a multi-stage pressurization capability to increase the range, so that it can cover fire sources at a distance and has strong penetration. It can effectively deal with complex fire scene environments, while having high fire extinguishing efficiency and saving water resources. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Depend on Figures 1 to 6The present invention includes a device body 1, with a water inlet pipe 3 fixedly installed at the bottom of the device body 1, a drive motor 2 fixedly installed on one side of the device body 1, the output end of the drive motor 2 extending into the interior of the device body 1 and fixedly installed with an impeller 4, the side of the impeller 4 away from the drive motor 2 being rotatably connected to the inner wall of one side of the device body 1 through a second shaft seat 21, a support plate 5 fixedly installed on one side of the top of the device body 1, a protective cover 6 fixedly installed on the upper part of one side of the support plate 5, a servo motor 7 fixedly installed inside the protective cover 6, a mounting shell 8 fixedly installed on one side of the device body 1, a water outlet hopper 9 fixedly installed in the middle of one side of the mounting shell 8, and four sealing baffles 10 fixedly installed in a ring at equal intervals inside the mounting shell 8. The output end of the servo motor 7 is provided with a transmission component, which is connected to the four sealing baffles 10. When the servo motor 7 is running, it outputs power to the four sealing baffles 10 through the transmission component, causing the four sealing baffles 10 to rotate and adjust the opening and closing size.

[0022] In use, water enters the main body 1 of the device through the inlet pipe 3. At the same time, the operator starts the drive motor 2 to drive the impeller 4 to rotate along the second shaft seat 21. When the impeller 4 rotates, it pressurizes the water through centrifugal force, thereby quickly throwing the water into the mounting shell 8. Simultaneously, the operator starts the servo motor 7 to drive the transmission component to operate. When the transmission component operates, it drives the four sealing baffles 10 to rotate and adjust the opening and closing size, thereby increasing the water pressure by limiting the water flow. Then the water will be discharged through the outlet bucket 9. Since the outlet bucket 9 is bucket-shaped with a small diameter at the inlet end and a large diameter at the outlet end, the water pressure will be further increased when it is sprayed out. This gives the fire monitor nozzle a multi-stage pressurization capability to increase the range, enabling it to cover long-distance fire sources. It also has strong penetration power and can effectively deal with complex fire scene environments. At the same time, it has high fire extinguishing efficiency and saves water resources.

[0023] The transmission assembly includes a drive shaft 15, which is fixedly mounted on the output end of the servo motor 7. A positioning sleeve 19 is rotatably mounted on the surface of the drive shaft 15. The surface of the positioning sleeve 19 is fixedly connected to the middle of one end of the protective cover 6. One end of the drive shaft 15 extends to the outside of the protective cover 6 and is fixedly mounted with a transmission gear 11. A first bearing seat 20 is rotatably mounted on the middle of one side of the transmission gear 11. A positioning seat 12 is fixedly mounted on the end of the first bearing seat 20 away from the drive shaft 15. The bottom of the positioning seat 12 is fixedly connected to the top of the mounting shell 8.

[0024] The operator starts the servo motor 7 to drive the drive shaft 15 to rotate inside the positioning sleeve 19. When the drive shaft 15 rotates, it drives the transmission gear 11 to rotate along the first shaft seat 20 on the positioning seat 12.

[0025] An opening 18 is provided in the middle of the top of the mounting shell 8. An annular groove 17 is provided in the inner wall of the mounting shell 8. An inner and outer gear rings 13 are slidably installed inside the annular groove 17. The transmission gear 11 passes through the opening 18 and enters the interior of the mounting shell 8 and meshes with the upper part of the inner and outer gear rings 13. Four gear discs 14 are circumferentially meshed with the inner wall of the inner and outer gear rings 13. One end of the four gear discs 14 is fixedly connected to four sealing baffles 10 respectively, and one side of each of the four gear discs 14 is rotatably connected to the inner wall of the mounting shell 8 through a rotating seat 16.

[0026] When the transmission gear 11 rotates, it drives the inner and outer gear rings 13 to rotate inside the annular slide groove 17. When the inner and outer gear rings 13 rotate, they drive the four sealing baffles 10 to rotate through the four gear discs 14 to adjust the opening and closing size, thereby increasing the water pressure by limiting the flow rate of water.
