Description
Technical Field
[0001] This utility model relates to the field of fire protection equipment, specifically a high-pressure water flow atomization uniformity adjustment nozzle device for fire pumps. Background Technology
[0002] A fire pump is a fire-fighting facility used in fire protection. It is classified into different types according to various classification methods. With its fully sealed, leak-free, and corrosion-resistant characteristics, it is widely used in environmental protection, water treatment, and fire protection departments. It is used to pump various liquids. In fire-fighting operations, the sprinkler head device is a key component that converts the high-pressure water output from the fire pump into fire-extinguishing water mist; its performance directly affects the fire-fighting effect.
[0003] Firefighting water may contain various impurities, such as mud, sand, and rust. Traditional sprinkler heads lack effective filtration and self-cleaning mechanisms, allowing impurities to easily enter the sprinkler head and clog its outlet, causing it to malfunction or have poor atomization. In a fire, clogged sprinklers can severely hinder firefighting efforts and delay the extinguishing process. Therefore, those skilled in the art have developed a high-pressure water flow atomization uniformity adjustment sprinkler head device for fire pumps to address the problems mentioned in the background section. Utility Model Content
[0004] The purpose of this invention is to provide a nozzle device for adjusting the uniformity of high-pressure water flow atomization in fire pumps, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A high-pressure water flow atomization uniformity adjusting nozzle device for a fire pump includes a water guide pipe and a nozzle body. The nozzle body is installed at the right end of the water guide pipe. An annular guide rail and a fixing ring are fixedly connected to the inner wall of the water guide pipe. A filter cylinder is fixedly connected to the left side of the fixing ring. A cross bracket is rotatably connected inside the annular guide rail. An impeller is fixedly installed on the left side of the cross bracket. Two connecting rods are fixedly connected to the right side of the cross bracket. Each connecting rod has cleaning brushes arranged at equal intervals fixedly connected to its outer surface, and the cleaning brushes are in contact with the filter cylinder. Multiple atomizing guide vanes are fixedly connected to the inner wall of the water guide pipe. A flow regulating valve is installed on the outer surface of the water guide pipe.
[0007] As a further improvement of this utility model: a connecting ring is provided at the left end of the water guide pipe, and multiple bayonets are provided inside the connecting ring.
[0008] As a further improvement of this utility model, the outer surface of the water guide pipe is fitted with an anti-slip sleeve.
[0009] As a further improvement of this utility model: a guide rail is fixedly connected to the left side of the fixing ring, and the right end of each connecting rod is slidably connected to the inside of the guide rail.
[0010] As a further embodiment of this utility model: a fixing rod is fixedly connected to the inner wall of the water guide pipe, and a spiral guide wheel is fixedly connected to the outer surface of the fixing rod, with multiple water guide ports opened on the outer surface of the spiral guide wheel.
[0011] As a further improvement of this utility model, a flow guide is fixedly connected to the left side of the annular guide rail.
[0012] As a further improvement of this utility model, both the nozzle body and the water guide tube are made of copper alloy.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The high-pressure water flow atomization uniformity adjusting nozzle device of this fire pump can guide and disperse the high-pressure water flow through multiple atomizing guide vanes on the inner wall of the water guide pipe. This allows the flow rate and direction of the water flow to be reasonably adjusted before passing through the nozzle body, laying the foundation for subsequent uniform atomization. Moreover, the spiral guide wheel and the water guide port on its outer surface further guide the water flow in a spiral shape, making the water flow more evenly distributed in the water guide pipe, thereby improving the uniformity of the final atomization effect.
[0015] II. The high-pressure water flow atomization uniformity adjustment nozzle device of this fire pump utilizes a filter cartridge to filter impurities in the water flow, preventing impurities from entering the nozzle body and causing blockage, thus affecting the normal operation of the nozzle. Under the impact of the water flow, the impeller drives the cross bracket to rotate in the annular guide rail. The connecting rod and cleaning brush on the cross bracket also rotate accordingly. The cleaning brush continuously contacts the filter cartridge to clean the filter cartridge, preventing impurities from accumulating on the filter cartridge and keeping the filter cartridge unobstructed. This allows the water flow to pass more smoothly through the filter cartridge and the nozzle body, which helps to achieve uniform atomization. Attached Figure Description

[0024] Please see Figures 1-5In this embodiment of the utility model, the high-pressure water flow atomization uniformity adjustment nozzle device of the fire pump includes a water guide pipe 1 and a nozzle body 19. The nozzle body 19 is installed at the right end of the water guide pipe 1. An annular guide rail 6 and a fixing ring 11 are fixedly connected to the inner wall of the water guide pipe 1. A filter cylinder 12 is fixedly connected to the left side of the fixing ring 11. A cross bracket 7 is rotatably connected inside the annular guide rail 6. An impeller 8 is fixedly installed on the left side of the cross bracket 7. Two connecting rods 9 are fixedly connected to the right side of the cross bracket 7. Each connecting rod 9 has cleaning brushes 10 arranged at equal intervals fixedly connected to its outer surface, and the cleaning brushes 10 are in contact with the filter cylinder 12. Multiple atomizing guide vanes 18 are fixedly connected to the inner wall of the nozzle 1. A flow regulating valve 3 is installed on the outer surface of the water guide tube 1. The filter cylinder 12 can filter impurities in the water flow to prevent impurities from entering the nozzle body 19 and causing blockage, which would affect the normal operation of the nozzle. The impeller 8 drives the cross bracket 7 to rotate in the annular guide rail 6 under the impact of the water flow. The connecting rod 9 and cleaning brush 10 on the cross bracket 7 also rotate accordingly. The cleaning brush 10 continuously contacts the filter cylinder 12 to clean the filter cylinder 12, prevent impurities from accumulating on the filter cylinder 12, keep the filter cylinder 12 unobstructed, and make the water flow more smoothly through the filter cylinder 12 and the nozzle body 19, which helps to achieve uniform atomization.
[0025] A connecting ring 4 is provided at the left end of the water guide pipe 1. The connecting ring 4 has multiple slots 5 inside, which facilitates quick connection with the outlet pipe of the fire pump, improving installation efficiency and ensuring a firm and reliable connection that will not loosen under the impact of high-pressure water flow. The outer surface of the water guide pipe 1 is covered with an anti-slip sleeve 2, which increases the friction when the operator holds the pipe, making the operator more stable when operating the nozzle. A guide rail 13 is fixedly connected to the left side of the fixing ring 11. The right end of each connecting rod 9 is slidably connected to the inside of the guide rail 13, allowing the connecting rod 9 to slide along the inside of the guide rail 13, thus improving its rotational stability.
[0026] A fixed rod 15 is fixedly connected to the inner wall of the water guide pipe 1, and a spiral guide wheel 16 is fixedly connected to the outer surface of the fixed rod 15. Multiple water guide ports 17 are opened on the outer surface of the spiral guide wheel 16. The spiral guide wheel 16 and the water guide ports 17 can further refine the small water flow into uniform water mist particles under the action of rotation or spiral motion, so as to achieve efficient atomization. A guide component 14 is fixedly connected to the left side of the annular guide rail 6. The guide component 14 can guide the water flow to impact the impeller 8 more smoothly, so that the impeller 8 rotates more stably and efficiently. The nozzle body 19 and the water guide pipe 1 are both made of copper alloy. Copper alloy has good corrosion resistance and strength and can withstand the impact of high-pressure water flow and harsh environment in fire fighting operations.
[0027] The working principle of this utility model is as follows: The device is installed on the fire pump via the connecting ring 4 and the bayonet 5. By adjusting the opening of the flow regulating valve 3, the water flow rate entering the nozzle can be precisely controlled. When the water flows through the guide pipe 1, the impeller 8 drives the cross bracket 7 to rotate within the annular guide rail 6 under the impact of the water flow. The connecting rod 9 and the cleaning brush 10 on the cross bracket 7 also rotate accordingly. After the water flows through the filter cylinder 12, it is guided by the filter cylinder 12, the spiral guide wheel 16, and the atomizing guide plate 18. The spiral guide wheel 16 and its outer surface guide... The water inlet 17 guides the water flow in a spiral shape, and the atomizing guide plate 18 can guide and disperse the high-pressure water flow. Finally, the water is atomized and sprayed out through the nozzle body 19. During the atomization spraying process, the connecting rod 9 and the cleaning brush 10 also rotate, which will cause the connecting rod 9 and the cleaning brush 10 to rotate as well. The rotation of the cleaning brush 10 continuously contacts the filter cylinder 12 to clean the filter cylinder 12, prevent impurities from accumulating on the filter cylinder 12, keep the filter cylinder 12 unobstructed, and ensure that the nozzle body 19 and the flat water guide pipe 1 can work continuously and stably.
