6 turns per minute of structure M power output shaft speed, the whole circle of rotation one needs 10 seconds, so, after motor decelerating mechanism M work once electrified
When its shaft rotates clockwise 5 seconds, connecting tube 9 can rotate clockwise 180 degree, its shaft after motor decelerating mechanism M work once electrified
When rotating counterclockwise 5 seconds, connecting tube 9 can inverse needle rotation 180 degree return to rotate clockwise 180 degree before initial position, guarantee that this is new
The normal work of type；Since the utility model hose 4 has longer surplus with flexible, 4 length of hose, the height of hose 4, which is higher than, to be connected
Elasticity is hung on the ceiling and had to the height of adapter tube 9, spring 5, so, when 9 left-right rotation of connecting tube, hose 4, spring 5 will not
Any obstruction is caused to the rotation of connecting tube 9.After its inner spool of electromagnetic water valve DC work once electrified is opened, the water in running water pipe
Electromagnetic water valve DC, the water inlet pipe 11 that can be opened through spool enter in connecting tube 9, and spray respectively from five 8 lower ends of sparge pipe, by
It is in rotary state in connecting tube 9 this moment, connecting tube 9 will drive five 8 left-right rotations of sparge pipe water spray of lower end, due to five
For 8 lower end of sparge pipe towards difference, 9 left and right ends of connecting tube can realize that 180 degree rotates respectively, so five sparge pipes 8 when fire extinguishing
It can accomplish the Multidirectional water spraying covering of ignition point, the extinguishing effect reached as far as possible.After the utility model uses once, next time is used
Before, it needs connecting tube 9 to return to initial position, external 24V power supply is respectively connected to motor decelerating mechanism M positive and negative polarities power supply this moment
Input terminal or motor decelerating mechanism M negative and positive the two poles of the earth power input, so that it may realize that the power output shaft of motor decelerating mechanism drives
Connecting tube 9 returns to initial position, and the power output shaft of specific motor decelerating mechanism returns to initial position, user to the left or to the right
According to 9 specific location of connecting tube operation can, 9 right part of connecting tube is towards left end, then external 24V power supply is just respectively connected to electricity
Machine deceleration mechanism M positive and negative polarities power input, 9 right part of connecting tube is towards rear right end, then just external 24V power supply is connect respectively
Entering motor decelerating mechanism M negative and positive the two poles of the earth power input can not grasp always as long as fire does not occur for the above-mentioned process of the utility model
Make, therefore will not have any impact to normal use.The utility model needs several sets to match as existing common automatic fire extinguisher
It closes and uses, thus the fire extinguishing coverage effect played to security area.The every set of the utility model is compared to existing every set automatic fire extinguisher
It can accomplish the Multidirectional water spraying covering of ignition point, the extinguishing effect reached as far as possible.Relay K1, K2, K3 are models
