Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fire fighting equipment, concretely relates to a fire monitor nozzle capable of preventing foreign matters from entering and draining. BACKGROUND

[0002] As an efficient and long-range fire extinguishing equipment, the fire monitor is widely used in high-risk fire places such as industrial facilities, petrochemical plants and large warehouses. In the fire extinguishing operation, the nozzle design of the fire monitor directly affects the fire extinguishing efficiency and the service life of the equipment. The traditional fire monitor nozzle mainly focuses on efficient water spraying and control of the spraying flow, but its reliability and functional integrity gradually show limitations in the face of complex environments. Specifically, the design of the existing fire monitor nozzle is often relatively simple in structure, and it is difficult to balance the functions of preventing foreign matter invasion and drainage. Especially in the long-term static or non-working state, the nozzle is easily invaded by dust, insects and other foreign matters, and even blocked in the high humidity or impurity-containing water environment, thereby seriously affecting the fire extinguishing capacity of the equipment. With the rapid development of intelligent technology, people have higher requirements for the functionality, intelligence and environmental adaptability of the fire monitor nozzle.

[0003] At present, the common fire monitor nozzle design mainly has two types: one type is to set a fixed water flow core inside the nozzle, and to realize a certain drainage capacity through the spatial gap with the spray pipe. However, this design lacks effective sealing measures, which makes it easy for dust, insects and other foreign matters to enter the inside of the spray pipe, and long-term accumulation may cause blockage or equipment damage; the other type is to add a spring structure inside the nozzle, and to realize the sealing function by driving the water flow core to act through the water pressure. Although this scheme can avoid foreign matter invasion to a certain extent, since the adhesion of the water flow core and the spray pipe depends on the elastic action of the spring, if the sealing is not strict, it is easy to cause long-term dripping phenomenon. In addition, in the non-spraying state, this kind of design often has difficulty in quickly emptying the residual water in the pipeline, which causes water accumulation in the equipment, further aggravating the corrosion risk of the equipment. In view of the above shortcomings, it can be seen that the existing technology is difficult to balance between preventing foreign matter invasion and effective drainage, and also lacks intelligent, remote control and other functions, which cannot meet the diversified needs of modern fire fighting equipment.

[0018] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

"In one embodiment" appearing in different places in this specification does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0020] Thirdly, the present application is described in detail in conjunction with the schematic diagram, and in order to facilitate the description, the cross-sectional view of the device structure will be partially enlarged without the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present application. In addition, three-dimensional spatial dimensions including length, width and depth should be included in actual manufacturing.

[0021] Referring to Figs. 1 to 4 As shown in the figure, the fire monitor nozzle includes a nozzle tube 10, a water flow core 20, an adjusting screw assembly 30, an extension spring 50, and an electromagnetic coil 60, and other core components. The close cooperation and synergy of these components enable stable operation under various working conditions, with the dual functions of preventing foreign matter from entering and draining water. The following elaborates on the functional characteristics and working process of the fire monitor nozzle from the aspects of structural design, working principle, and characteristics.

[0022] Firstly, the nozzle tube 10 part of the fire monitor nozzle serves as the main body of the water flow channel, bearing the functions of guiding water flow and carrying internal components. The nozzle tube 10 is provided with a water inlet 11 and a water outlet 12, the water inlet 11 is used to connect the fire water source, and the water outlet 12 is designed in a horn shape, which can effectively expand the water spraying range and enhance the fire extinguishing effect. A fixed block 40 is installed on the nozzle tube 10 near the water inlet 11, and the fixed block 40 is provided with a mounting groove 41 for accommodating the adjusting screw assembly 30.

[0023] The water flow core 20 is an important component of the nozzle, directly responsible for controlling the opening and sealing of the water outlet 12. In the static state, the water flow core 20 is in sealing contact with the water outlet 12, and the spring force maintains this state, preventing external foreign matter (such as dust, insects, etc.) from entering the pipeline and causing blockage. In order to enable the water flow core 20 to smoothly transition between different states, one end is connected to the sliding end 32 through the adjusting screw 31 and cooperates with the extension spring 50. The adjusting screw assembly 30 includes the adjusting screw 31 and the sliding end 32, one end of the adjusting screw 31 is connected to the water flow core 20, the other end passes through the mounting groove (41) on the nozzle tube 10, and is fixed on the sliding end 32. This structural design not only ensures that the water flow core 20 can move stably when subjected to external force or magnetic force, but also ensures that it maintains a sealed state when it returns to the initial position.

[0024] In order to provide the reset force of the water flow core 20, the adjusting screw 31 is sleeved with the extension spring 50. One end of the spring is in contact with the fixed block 40 of the nozzle tube 10, and the other end is connected to the adjusting screw 31. When the system is in a static state, the spring maintains a certain compression state, giving the water flow core 20 an inward pressure, ensuring the sealing effect between the water outlet 12 and the water flow core 20. In the water spraying or water draining operation, the extension spring 50 can adapt to the motion state of the water flow core 20 and the adjusting screw 31, further compressing or relaxing, thereby providing reliable support for the dynamic balance of the system.

[0025] The electromagnetic coil 60 is an important component for realizing remote control and automatic operation. It is fixedly installed outside the fixed block 40 of the spray pipe 10. When drainage is needed, the electromagnetic coil 60 is powered, and the magnetic force generated by the coil can push the adjusting screw assembly (30) to move outward. Under the action of the magnetic force, the adjusting screw 31 drives the water flow core 20 to move away from the water outlet 12, forming a drainage channel, so that the accumulated water in the pipeline is discharged through the cannon muzzle. The design of the electromagnetic coil 60 not only provides convenience for operation, but also enables the cannon muzzle of the fire monitor to have a remote control function, thereby improving the intelligent level of the equipment.

[0026] In specific work, the cannon muzzle of the fire monitor can be switched between the static state, the water spraying state and the drainage state, thereby ensuring its multifunctionality. In the static state, the water flow core 20 is in sealed contact with the water outlet 12, and the spring is in a compressed state, thereby preventing foreign matters from entering the pipeline. In addition, the electromagnetic coil 60 in the static state is in a power-off state, the adjusting screw assembly 30 is kept stable, and the system is in a closed state. This design can effectively protect the internal structure and prolong the service life of the equipment.

[0027] When the fire monitor needs to spray water, the water supply valve is opened, water flows into the equipment through the spray pipe 10, and a certain water pressure is formed to act on the water flow core 20. The water flow core 20 moves outward under the action of the water pressure and moves synchronously with the adjusting screw 31, thereby compressing the extension spring 50 and moving away from the water outlet 12 to form a water flow channel. At this time, water is sprayed at high speed from the horn-shaped water outlet 12, thereby completing the fire extinguishing task. After the water spraying is completed, the water supply valve is closed, the water flow pressure disappears, and the elasticity of the extension spring 50 promotes the water flow core 20 to return to the original position and reseal the water outlet 12, thereby preventing further water leakage.

[0028] In the drainage state, the electromagnetic coil 60 is powered, the magnetic force generated by the coil pushes the adjusting screw assembly 30 to move outward, and the water flow core 20 moves away from the water outlet 12 to open the drainage channel. At this time, the accumulated water in the pipeline is discharged through the cannon muzzle. After the drainage is completed, the power supply of the electromagnetic coil (60) is disconnected, and the elastic force of the extension spring 50 resets the water flow core 20 and the adjusting screw assembly 30 to reseal the water outlet 12. This drainage method can effectively remove the residual water in the pipeline, avoid corrosion of the equipment caused by long-term water storage, and ensure the safety and reliability of the system in the next use.

[0029] The embodiments are only used to illustrate the technical solutions of the utility model and not to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the utility model, and all of them should be covered in the scope of the claims of the utility model.
