[0053] The present invention discloses a nozzle for energy storage fire fighting. When a fire is detected, the valve opens, and the liquid fire extinguishing agent is fed into the liquid inlet channel 12. Under the action of pressure, the one-way sealing component 15 opens, and the liquid fire extinguishing agent is fed from the liquid inlet channel 12 into the atomizing chamber 11. Under the action of the nozzle swirl core 14, the atomized liquid fire extinguishing agent is ejected from the nozzle body 13.

The atomized liquid fire extinguishing agent can cover the fire area with the largest area, thereby achieving the purpose of rapid fire fighting. The energy storage fire fighting nozzle provided by the present invention is suitable for the lithium battery PACK electric box fire extinguishing system. The product has a compact structure, high integration, and good atomization effect. Under different pressures of 1.5 bar, 5.0 bar, 10 bar, and 18 bar, the atomization angle (the atomization angle varies between 40°-90°) also increases accordingly, thereby producing different atomization effects.

[0054] In one embodiment, an internal thread 16 adapted for connection with the nozzle body 13 is provided on the inner wall of the atomizing chamber 11 , and an external mounting thread 17 is provided on the side end of the connecting base 10 near the top.

[0055] The beneficial effects of the above technical solution are:

[0057] In one embodiment, the connecting base 10 is integrally formed with a mounting base 18 at one side end, a mounting pressing plate 19 is mounted at the bottom end of the mounting base 18 through a hexagonal nut 21, four hexagonal nuts 21 are arranged on the mounting base 18, a central through hole is formed in the center of the mounting pressing plate 19 for the connecting base 10 to pass through, and a buffer rubber pad 22 is clamped between the mounting base 18 and the mounting pressing plate 19.

[0058] The working principle and beneficial effects of the above technical solution are:

[0059] The mounting pressing plate 19 is detachably mounted at the bottom end of the mounting base 18 through the hexagonal nut 21, and the buffer rubber pad 22 is clamped between the mounting base 18 and the mounting pressing plate 17, thereby improving the sealing performance of the nozzle.

The greater the pressure, the more the reset spring 28 is retracted, and the greater the flow of liquid extinguishing agent sent into the atomizing chamber 11. That is, under different pressures of 1.5 bar, 5.0 bar, 10 bar and 18 bar, the reset spring 28 is retracted, and the flow of liquid extinguishing agent sent into the atomizing chamber 11 is gradually increased, and the atomizing angle (the change range of the atomizing angle is between 40°-90°) is also increased, thereby different atomizing effects are obtained.

[0068] As shown in Figures 4 to 9 The embodiment also discloses a manufacturing method of an energy storage fire-fighting nozzle, which is applied to the energy storage fire-fighting nozzle and comprises the following steps:

[0074] Step 6: sequentially assembling the buffer rubber pad 22, the pack panel 23 and the mounting pressing plate 19 from the bottom end of the mounting base 18, and tightening the hexagonal nut 21.

[0075] The working principle and beneficial effects of the above technical scheme are as follows:

[0077] In another embodiment, in step 2, the inner wall of the liquid inlet channel 12 near the atomizing chamber 11 is flared by a flaring unit, which comprises a lifting assembly 29 and a flaring assembly 20 installed at the bottom end of the lifting assembly 29, wherein the flaring assembly 20 comprises:

[0078] a cylinder 31, the top end of which is installed on the lifting assembly 29, the bottom end of which is open, and the surface of which is uniformly provided with air outlets;

[0079] an upper rotating disc 32 and a lower rotating disc 33, which are installed in the cylinder 31, and the cylinder 31 near the top and the bottom end of the cylinder 31 are respectively provided with limiting rings 34 for limiting the upper rotating disc 32 and the lower rotating disc 33;

[0081] a grinding block assembly, which is installed on the vertical pipe 35 in a lifting manner.

[0082] The working principle and beneficial effects of the above technical solution are as follows:

[0084] In another embodiment, the flaring assembly 20 further comprises:

[0085] The outer gear ring is installed on the upper disc 32.

[0086] The driving motor 36 is installed at the top of the cylinder 31, and a rotating gear 37 engaged with the outer gear ring is installed at the output end of the driving motor 36.

[0087] The working principle and beneficial effects of the above technical solution are:

[0088] The driving motor 36 works to drive the rotating gear 37 installed at the output end of the driving motor 36 to rotate, under the cooperation of the rotating gear 37 and the outer gear ring, the upper disc 32 connected with the outer gear ring is driven to rotate, thereby driving the lower disc 33 connected with the upper disc 32 through the vertical pipe 35 to rotate synchronously, thereby driving the grinding block assembly installed on the vertical pipe 35 to rotate, and the grinding block assembly grinds the position close to the atomizing chamber 11 on the inner wall of the liquid inlet channel 12 to form the flared portion 27.

[0089] In another embodiment, the grinding block assembly comprises:

[0090] A magnetic slider 38 is slidingly connected in the vertical pipe 35;

[0091] An outer magnetic ring 39 is sleeved on the vertical pipe 35, and the outer magnetic ring 39 is adapted to the magnetic slider 38;

[0092] L-shaped air outlet pipes 30 are installed on the vertical pipe 35 through one-way valves 41, and two L-shaped air outlet pipes 30 are centrally symmetrically arranged, and the surfaces of the L-shaped air outlet pipes 30 are uniformly provided with inner air outlets;

[0093] A grinding block 49 is arranged near the bottom end of the cylinder 31, two connecting arms 42 are symmetrically arranged through the vertical pipe 35, and the connecting arms 42 are connected between the grinding block 49 and the outer magnetic ring 39;

[0094] A pull rope assembly is installed on the upper turntable 32 and the lower turntable 33, respectively, and the limiting ring 34 is provided with a C-shaped gear ring 43 for driving the pull rope assembly to work.

[0095] The working principle and beneficial effects of the above technical solution are:

[0096] In combination with Figure 5 , Figure 8 and Figure 9When the grinding block assembly is attached to the inner wall of the atomizing chamber 11, the driving motor 36 is operated to drive the rotating gear 37 installed on the output end of the driving motor 36 to rotate. Under the cooperation of the rotating gear 37 and the outer gear ring, the upper turntable 32 connected with the outer gear ring is driven to rotate, thereby driving the lower turntable 33 connected with the upper turntable 32 through the vertical pipe 35 to rotate synchronously, thereby driving the grinding block assembly installed on the vertical pipe 35 to rotate. The grinding block assembly grinds the position of the inner wall of the liquid inlet channel 12 close to the atomizing chamber 11 to form the flared portion 27. Preferably, when the pull rope assembly located on the lower turntable 33 rotates, it contacts the C-shaped gear ring 43, thereby pulling the magnetic sliding block 38 located in the vertical pipe 35 to descend. The one-way air supplement valve 40 installed at the top end of the vertical pipe 35 supplements air into the vertical pipe 35, and the magnetic sliding block 38 pressurizes the air at the bottom of the vertical pipe 35 into the L-shaped air outlet pipe 30 located at the right end and blows it out through the inner air outlet of the L-shaped air outlet pipe 30. After the upper turntable 32 rotates 180°, the pull rope assembly installed on the upper turntable 32 rotates and contacts the C-shaped gear ring 43, thereby pulling the magnetic sliding block 38 located in the vertical pipe 35 to ascend. The one-way air supplement valve 40 installed at the bottom end of the vertical pipe 35 supplements air into the vertical pipe 35, and the magnetic sliding block 38 pressurizes the air at the top of the vertical pipe 35 into the L-shaped air outlet pipe 30 located at the left end and blows it out through the inner air outlet of the L-shaped air outlet pipe 30. In this way, when the magnetic sliding block 38 ascends and descends in the vertical pipe 35, the outer air outlets on the surface of the cylinder 31 continuously spray air flow, which not only sweeps the atomizing chamber 11 but also continuously sweeps the grinding block assembly, thereby achieving rapid cooling of the grinding block assembly. This prevents the grinding block assembly from working at a high temperature for a long time, which reduces the service life of the grinding block assembly.

[0097] Further, in the descending process of the magnetic sliding block 38, the outer magnetic ring 39 sleeved on the vertical pipe 35 is driven by magnetism, the grinding block 49 connected with the outer magnetic ring 39 through the connecting arm 42 descends at the bottom end of the cylinder 31, and grinds the position of the inner wall of the liquid inlet channel 12 close to the atomizing chamber 11 to form the flared portion 27. Conversely, in the ascending process of the magnetic sliding block 38, the outer magnetic ring 39 sleeved on the vertical pipe 35 is driven by magnetism, the grinding block 49 connected with the outer magnetic ring 39 through the connecting arm 42 ascends at the bottom end of the cylinder 31, and the grinding block 49 exits the liquid inlet channel 12, thereby completing one ascending and descending of the grinding block 49.

[0098] In another embodiment, the pull rope assembly comprises:

[0099] The support frame 44 is installed on the upper turntable 32 and the lower turntable 33, respectively;

[0100] The guide wheel 45 is installed on the support frame 44;

[0101] A rope wheel 46 and a transmission gear 47 are coaxially installed on the support frame 44, and the transmission gear 47 is engaged with the C-shaped gear ring 43;

[0102] A pull rope 48, one end of which extends into the vertical pipe 35 and is connected with the magnetic slider 38, and the other end of which is wound around the rope wheel 46 after passing through the guide wheel 45.

[0103] The working principle and beneficial effects of the above technical solution are as follows:

[0104] When the pull rope assembly located at the lower turntable 33 rotates, the transmission gear 47 is in contact with the C-shaped gear ring 43, thereby driving the rope wheel 46 coaxially installed on the support frame 44 to rotate, the rope wheel 46 winds the pull rope 48 thereon, thereby pulling the magnetic slider 38 connected with the pull rope 48 to descend in the vertical pipe 35, and when the upper turntable 32 rotates by 180°, the pull rope assembly installed on the upper turntable 32 rotates, the transmission gear 47 is in contact with the C-shaped gear ring 43, thereby driving the rope wheel 46 coaxially installed on the support frame 44 to rotate, the rope wheel 46 winds the pull rope 48 thereon, thereby pulling the magnetic slider 38 connected with the pull rope 48 to ascend in the vertical pipe 35, so that the outer air outlet on the surface of the cylinder 31 continuously sprays air flow when the magnetic slider 38 ascends and descends in the vertical pipe 35.

[0105] Obviously, the above embodiments are only examples for clearly illustrating the present application, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
