In the present invention, the top of the present apparatus is arranged in 4 spiral of guiding rib, guiding rib when meeting when water flow is flowed into from the external world
4 effect and the phenomenon that show helical flow, water flow is smaller to the active force that guiding rib 4 is downward when water flow is smaller, otherwise makees
It is firmly larger.When water flow is smaller to 4 active force of guiding rib, itself equally there is certain elasticity to spring because of guiding rib 4, this
When each side of guiding rib 4 it is more straight.At this time guiding rib 4 to the drift angle of current deflecting be more nearly with it is horizontal, when water flow compared with
Hour can be such that water flow rotates with it, and biggish air column be generated in the middle part of water flow, so that the hum of water flow is smaller；
When water flow is more, flow velocity is larger, water flow is bigger to the active force of guiding rib 4, and guiding rib 4 has becoming for elongation at this time
Gesture so that the lower end of guiding rib 4 is slided with respect to rubber block 5, and is wrapped in the lower end of guiding rib 4 more in shaft 7, clockwork spring
8 have drive shaft 7 rotate make guiding rib 4 wind effects, guarantee activity more freely, reduce Caton the phenomenon that exist；
The drift angle that guiding rib 4 is elongated and locates it not at this time is larger, and the flows at angles for driving water flow bigger with drift angle makes
Obtaining also can generate apparent air column at the middle part of inner tube 2 when water flow is significantly greater, accelerate the flowing of water, and reduce noise
It generates.
In the present apparatus be provided with multiple spiral bars 9, for guarantees by guiding rib 4 guiding and the water flow of rotational flow is played and is held
The effect of continuous rotational flow, when water flow is smaller, water flow is smaller to the active force of spiral bar 9, is unable to drive choke block 12 in work
It is moved downward in dynamic slot 11, otherwise when water flow is larger, since spiral bar 9 is flexible rubber material, so at this time can
Choke block 12 is driven to move downward in loose slot 11；
Due to there is gag lever post 14 above the first rotor plate 15 when choke block 12 moves downward, two the first rotor plates 15 can be same
When be in horizontality so that the negotiable sectional area of through-hole is smaller on choke block 12.Hydraulic oil 16 can only flow at a slow speed
The top of choke block 12, so to move downward speed slower for choke block 12；
When water flow reduces, choke block 12 can move upwards under its own elastic reaction, at this time due to the first rotor plate
15 lower sections only have the first spring 13, so the first rotor plate 15 can be rotated so that the sectional area of through-hole is larger herein, hydraulic oil 16
The lower section that choke block 12 can quickly be flowed to, enables 12 Rapid reset of choke block, can preferably guarantee water flow in inner tube 2
Drift angle is smaller and maximumlly reduces the generation of noise.
Higher temperature, the distilled water meeting in flow container 36 can be experienced at first when occurring fire in building, at outer tube 1
It is quickly evaporated to gas, and then the piston 34 in cylinder 33 is pushed to move upwards, can also to steam since fire temperature is higher
The evaporation rate of distilled water is exceedingly fast, until block 40 pushes sliding sleeve 39 and crosses sliding sleeve 39, and then drives sliding sleeve 30 by push rod 35
Quickly move upwards, under the action of the first rotating bar 31 and the second rotating bar 32 band movable slider 24 and third rotor plate 25 to
Two sides movement；
Sliding block 24 pushes the second straight-bar 22 to move therewith, drives 21 turns of spray head to when moving far from 29 direction of straight-bar
Dynamic until spray head 21 is in horizontality, spray head 21 will push the rotation of the second rotor plate 18 during this, so that spray head 21 is direct
It is opposite with the external world；Third rotor plate 25 rotates the inside that can stretch to inner tube 2, so that the water in inner tube 2 can be flowed to quickly
At mantle 27, and there are more apparent pressure, water therein can flow at spray head 21 under the effect of the pressure through hose,
It is sprayed to the external world through spray head 21 again, generates certain extinguishing effect to extraneous.
Although outer tube 1, inner tube 2, connecting plate 3, guiding rib 4, rubber block 5, sealing plate 6, shaft is used more herein
7, clockwork spring 8, spiral bar 9, coffer 10, loose slot 11, choke block 12, the first spring 13, gag lever post 14, the first rotor plate 15,
Hydraulic oil 16, the second rotor plate 18, the first sealing joint strip 19, the first straight-bar 20, spray head 21, the second straight-bar 22, is slided blocking plate 17
Slot 23, sliding block 24, third rotor plate 25, the second sealing joint strip 26, mantle 27, hose 28, straight-bar 29, sliding sleeve 30, first rotate
Bar 31, the second rotating bar 32, cylinder 33, piston 34, push rod 35, flow container 36, conduit 37, fixed link 38, loop bar 39, block 40,
The terms such as second spring 41, but it does not exclude the possibility of using other terms.The use of these items is only for more convenient
Ground describes and explains essence of the invention；Being construed as any additional limitation is disagreed with spirit of that invention
