[0035] Referring to Figures 1 to 8 The embodiment provides a perfluorohexanone gas fire extinguishing device, which comprises a tank body 10, a spray pipe 20, a stop block 30 and a driving mechanism 40.

[0036] The spray pipe 20 is in communication with the tank body 10, and a plurality of mounting grooves 21 extending in the axial direction are formed in the end of the spray pipe 20 away from the tank body 10, and the end of the mounting grooves 21 away from the tank body 10 is open. The bottom surface of the mounting groove 21 is a slope; the stop block 30 is provided with a plurality of stop blocks 30, which are slidingly arranged in the corresponding mounting grooves 21, and the end of the sliding block can slide out of the open end of the mounting groove 21. When the end of the stop block 30 slides out of the open end of the mounting groove 21, it gradually approaches the axis of the spray pipe 20 and partially blocks the nozzle of the spray pipe 20. The driving mechanism 40 is used to drive the stop block 30 to slide.

[0037] In this embodiment, the stop block 30 is driven by the driving mechanism 40 to slide out of the open end of the mounting groove 21 and partially block the nozzle of the spray pipe 20, thereby controlling the opening size of the nozzle of the spray pipe 20, and further controlling the spraying distance of the perfluorocyclohexanone liquid sprayed out of the spray pipe 20, which makes the perfluorocyclohexanone gas fire extinguishing device can be installed first, and then the spraying distance can be adjusted according to the fire extinguishing point, and the installation convenience is improved.

[0038] In one embodiment, the end of the stop block 30 away from the axis of the spray pipe 20 is provided with a matching hole 31.

[0039] The driving mechanism 40 includes a driving sleeve 41 and an annular driving rope 42.

[0040] The driving sleeve 41 is gap-set on the end of the spray pipe 20, and a plurality of strip-shaped limiting holes 411 in the axial direction are formed on the driving sleeve 41. The annular driving rope 42 is elastic, the annular driving rope 42 passes through the plurality of matching holes 31 at the same time, and the annular driving rope 42 is coaxial with the driving sleeve 41. The end of the stop block 30 away from the axis of the spray pipe 20 is slidingly fitted with the strip-shaped limiting hole 411, specifically, a limiting column is fixedly connected on the inner wall of the strip-shaped limiting hole 411, the limiting column points to the axis direction of the driving sleeve 41, and the end of the stop block 30 is provided with a groove, which is slidingly fitted with the outer wall of the limiting column. The annular driving rope 42 is located outside the driving sleeve 41. The stop block 30 can slide in the strip-shaped limiting hole 411 to approach or move away from the axis of the spray pipe 20. The driving sleeve 41 can be kept stationary on the spray pipe 20.

[0041] In this embodiment, the driving sleeve 41 slides out of the end of the spray pipe 20 in the axial direction, and under the driving of the elastic annular driving rope 42, the stop block 30 in the strip-shaped limiting hole 411 approaches the axis of the spray pipe 20, at this time, the end of the stop block 30 slides out of the open end of the mounting groove 21 and slides obliquely to the axis of the spray pipe 20, thereby forming a certain range of shielding to the nozzle of the spray pipe 20, and further reducing the area of the nozzle of the spray pipe 20, so that the perfluorocyclohexanone liquid sprayed in the spray pipe 20 can be sprayed farther.

[0042] In one embodiment, the surface of the block 30 close to the bottom surface of the mounting groove 21 is a contact surface, and a plurality of limiting openings 32 are formed on the contact surface and distributed along the length direction of the block 30. The driving mechanism 40 further comprises a locking protrusion 43 connected with the bottom surface of the mounting groove 21, and the locking protrusion 43 is engaged with the limiting opening 32.

[0043] In this embodiment, the driving sleeve 41 moves the block 30 in the axial direction on the end of the spray pipe 20 to slide in the strip-shaped limiting hole 411. Under the action of the annular driving rope 42, the contact surface of the block 30 keeps in contact with the bottom surface of the mounting groove 21, and when the block 30 moves in the mounting groove 21, the locking protrusion 43 cooperates with the limiting opening 32 to prevent the block 30 from easily sliding in the mounting groove 21, thereby locking the block 30 and the driving sleeve 41.

[0044] In one embodiment, the end of the block 30 close to the axis of the spray pipe 20 is blade-shaped, which makes the end of the block 30 block the nozzle of the spray pipe 20 after sliding out of the mounting groove 21, and the perfluorohexone liquid sprayed in the nozzle has less resistance when passing through the blade-shaped end of the block 30, thereby reducing the loss of kinetic energy and enabling the perfluorohexone liquid to be sprayed farther.

[0045] In one embodiment, a plurality of flow guide grooves 33 are formed on both sides of the blade-shaped end of the block 30 along the axial direction of the spray pipe 20, and the plurality of flow guide grooves 33 on one side of the block 30 are distributed along the radial direction of the spray pipe 20.

[0046] In this embodiment, the perfluorohexone sprayed in the spray pipe 20 is separated by the blade-shaped end of the block 30, thereby making the perfluorohexone liquid sprayed more uniformly, increasing the contact area between the perfluorohexone and the air, and thereby enabling the perfluorohexone to be vaporized and extinguished at the fire extinguishing point more quickly. In addition, the flow guide grooves 33 on both sides of the block 30 can guide and comb the perfluorohexone liquid passing through both sides of the block 30, so that the sprayed perfluorohexone liquid is further distributed uniformly in the air.

[0047] In one embodiment, a plurality of mounting grooves 21 are circumferentially distributed around the axis of the spray pipe 20. This enables the blocks 30 to be also circumferentially distributed around the axis of the spray pipe 20, thereby enabling the perfluorohexone liquid sprayed by the spray pipe 20 to be cut by the plurality of blocks 30, so that the perfluorohexone liquid sprayed by the spray pipe 20 is more uniformly distributed in the air.

[0048] In one embodiment, an arc-shaped mounting hole 22 extending along the axial direction of the spray pipe 20 is further formed between every two adjacent mounting grooves 21 on the end of the spray pipe 20.

[0049] The driving mechanism 40 further comprises an arc-shaped plate 44 and a connecting rod 45.

[0050] The arc-shaped plates 44 are provided in plurality, each of which is in sliding fit with the corresponding arc-shaped mounting hole 22. The connecting rods 45 are provided in plurality, one end of each of which is connected with the corresponding arc-shaped plate 44, and the other end of each of which is connected with the inner wall of the driving sleeve 41. The plurality of arc-shaped plates 44 and the plurality of blocks 30 enclose a cylindrical space, which is in communication with the nozzle head of the spray pipe 20.

[0051] In the embodiment, as the driving sleeve 41 slides out from the end of the spray pipe 20, the arc-shaped plates 44 and the blocks 30 also slide out synchronously, at this time, the blocks 30 partially shield the mouth of the spray pipe 20, and the arc-shaped plates 44 and the blocks 30 are jointly enclosed, so that the perfluorohexone liquid sprayed in the spray pipe 20 is cut by the blade-shaped end of the block 30 and then guided by the arc-shaped plates 44 without being scattered, thereby improving the spraying distance.

[0052] In one embodiment, a coaxial guide cone 23 is arranged in the mouth of the spray pipe 20; the tip of the guide cone 23 faces the inside of the spray pipe 20. A support rod is connected to the outer wall of the guide cone 23, and the end of the support rod away from the guide cone 23 is connected with the inner wall of the spray pipe 20.

[0053] In the embodiment, when the perfluorohexone liquid is sprayed, it is guided by the outer wall of the guide cone 23 and scattered to the blade-shaped end of the block 30, so that the sprayed perfluorohexone liquid is cut, and then the perfluorohexone liquid can contact more air after being sprayed, the vaporization efficiency is high, and the fire extinguishing efficiency is improved.

However, it can be understood that the embodiments of the utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail, so as not to obscure the understanding of the specification.
