[0023] The following will be combined with the appendix Figures 1 to 6This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] This utility model provides an improved Z-type sprinkler head for fire fighting using an energy storage battery box, such as... Figure 1-6 As shown in the figure, it includes a mounting base 1 and a special-shaped conveying pipe 6. A mounting structure is provided on one side of the mounting base 1, and a one-way sealing mechanism is provided on the inner side of the mounting base 1.

[0025] One end of the irregularly shaped conveying pipe 6 is fixedly connected to the connector 62. The connector 62 is inserted into the interior of the mounting base 1, and a sealing ring 63 is provided on the outside of the connector 62. The sealing ring 63 is engaged with the inner wall of the mounting base 1. Mounting holes are provided on one side wall of the mounting base 1 and the outer wall of the connector 62. A limiting bolt 9 is threaded into the inside of one side wall of the mounting base 1, and the limiting bolt 9 extends into the interior of the connector 62. A snap-fit ​​groove is provided on the other side wall of the mounting base 1. The outer wall of the connector 62 is fixedly mounted on the arc-shaped locking block 10, which is fitted and snap-fitted with the snap-fit ​​groove. The irregularly shaped conveying pipe 6 is Z-shaped. With the irregularly shaped conveying pipe 6, the limiting bolt 9, and the arc-shaped locking block 10, in use, the connector 62 is inserted into the interior of the mounting base 1, and the sealing ring 63 is engaged with the inner wall of the mounting base 1. The sealing ring 63 seals the interface to prevent leakage of liquid extinguishing agent under hydraulic pressure, improving the sealing performance of the device and allowing the nozzle to spray liquid extinguishing agent more effectively. Simultaneously, the use of a Z-shaped delivery pipe 6 allows liquid extinguishing agent or fire water to smoothly pass through the bend, bypassing obstacles in the battery box, and directly spraying to the point of ignition, thus effectively extinguishing the fire. Furthermore, limiting bolts 9 and arc-shaped clamps 10 limit the installation of connector 62, thereby positioning the installation of the Z-shaped delivery pipe 6 and preventing deviations in its direction and position, improving installation accuracy. The Z-shaped delivery pipe 6 enhances the device's flexibility, broadens its applicability, and facilitates its widespread use.

[0026] The other end of the irregularly shaped delivery pipe 6 is fixedly installed with a connector 2 61. The nozzle 7 is installed in the internal thread of the connector 2 61. A sealing ring 3 71 is set inside one end of the connector 2 61 to seal the connection between the nozzle 7 and the connector 2 61. A threaded interface ring 11 is set on the outside of one end of the mounting base 1 to facilitate quick and stable installation of the mounting base 1 with the liquid delivery system. The threaded interface ring 11 is connected to the delivery pipe fitting. The liquid extinguishing agent is delivered through the mounting base 1, connector 1 62, irregularly shaped delivery pipe 6, connector 2 61 and nozzle 7. The sealing ring 3 71 is used to seal the connection between the connector 2 61 and the nozzle 7 to prevent leakage of the liquid extinguishing agent. The nozzle 7 is conical with an inner diameter that increases from the inside to the outside, so that the liquid can be sprayed in an umbrella shape, making the spray range wider and forming a conical water curtain. It can isolate the fire source while extinguishing the fire, and the effect is good.

[0027] The mounting structure includes a protective pad 2, mounting bolts 3, washers 4, and nuts 5. The protective pad 2 is embedded inside one side wall of the mounting base 1. The mounting bolts 3 are threaded into the mounting base 1 and the protective pad 2, and the washers 4 are movably sleeved on the outside of the mounting bolts 3. The nuts 5 are threaded onto the outside of one end of the mounting bolts 3. The washers 4 are located on one side of the mounting base 1, and the nuts 5 are located on the other side of the mounting base 1. In use, the mounting base 1 is installed against the outer wall of the battery box, and then the protective pad 2 contacts the outer wall of the battery box, making the positioning between the mounting bolts 3 and the battery box more stable, less prone to gaps, and avoiding shaking. The nuts 5 are engaged with the inner wall of the battery box to limit the positioning of the mounting base 1. The protective pad 2 can prevent gaps in the battery box caused by the installation of the device, thus facilitating the sealing of the battery box.

[0028] The one-way sealing mechanism includes a limiting head 8, a second sealing ring 81, and a limiting spring 82. A limiting groove is formed inside one end of the connector 62 located inside the mounting base 1. The limiting head 8 is movably installed inside one end of the mounting base 1, and the second sealing ring 81 is embedded in the outer wall of the limiting head 8. The second sealing ring 81 engages with one end of the mounting base 1. A mounting groove is formed at the other end of the limiting head 8. One end of the limiting spring 82 engages with the limiting groove, and the other end engages with the limiting head 8. During use, the sealing mechanism is adjusted towards the mounting base. Liquid extinguishing agent is introduced into the installation base 1. Under the action of hydraulic pressure, the limiting spring 82 contracts, and the limiting head 8 gradually opens to seal the installation base 1. The liquid extinguishing agent is delivered into the installation base. The flow rate can be controlled by adjusting the hydraulic pressure. The greater the pressure, the more the limiting spring 82 contracts, and the greater the flow rate of liquid extinguishing agent delivered into the installation base 1. Consequently, the liquid flow rate sprayed from the nozzle 7 is greater, which can quickly extinguish the fire source. The flow rate can be controlled according to the size of the fire source, thus making the device more flexible.
