the external temperature is transmitted to the internal heat-sensitive substance through the temperature sensing disc 301, when the temperature reaches a target threshold value, the heat-sensitive substance changes phase, so that the pressure in the splash pan 7 increases, and since the positions of the first sliding sleeve 501 and the first sleeve 503 are fixed relative to the first sliding rod 401, the temperature sensing disc 301 drives the heat conducting rod 306 to move downward through the bottom plate 303, the first plug block 304 and the pressing ring 305 under the action of the pressure, so as to drive the first sliding rod 401 to slide downward through the first connecting rod 307, thereby driving the second sliding rod 402 to slide downward synchronously, so that the second plug block 403 and the end head 404 slide downward synchronously, the end head 404 drives the retainer ring 405 to move downward, and pushes the push block 604 to move into the third sleeve 601, so as to drive the first sliding block 603 and the third sliding rod 602 to move synchronously, and compress the spring, so that the fixture block 607 is released from the clamping groove 606, thereby disconnecting the support 5 and the retainer ring 10 from the top cover 15, the support frame 5 and the baffle ring 10 synchronously move downwards along the second connecting rod 13 and the second sliding block 14, and drive the temperature sensing system 3, the splash pan 7, the second sliding sleeve 8 and the second annular sliding block 9 to synchronously move downwards, meanwhile, the fire-fighting water gushes out from the bottom of the water receiving pipe 2, is cut by the connecting plate 505 and then contacts with the splash pan 7, so that the fire-fighting water splashes around to carry out fire-fighting operation;
resetting after fire-fighting operation:
along with the fire-fighting water contacts with splash box 7, the temperature of the heat-sensitive material in splash box 7 is reduced, and reverse phase transition occurs, make the pressure in splash box 7 reduce, thereby make temperature sensing system 3, slide mechanism 4, splash box 7, second sliding sleeve 8 and the relative support frame 5 of second ring-shaped piece 9 reset, after the fire control operation, external fire-fighting water is closed, upwards promote support frame 5 this moment, make fixture block 607 and third slide bar 602 block joint mutually can realize being connected fixedly of support frame 5 and top cap 15, meanwhile, end 404 and retaining ring 405 cup joint with water receiving pipe 2 again, in order to realize closing of water receiving pipe 2, after the whole mechanism resets, supply the fire-fighting water again and can accomplish the preparation work.
The base plate 303, the first plug block 304, the pressing ring 305 and the heat conducting rod 306 are made of the same material, so that the temperature of the base plate 303, the first plug block 304, the pressing ring 305 and the heat conducting rod 306 is the same as that of the temperature sensing disc 301, and the volume of the base plate 303, the first plug block 304, the pressing ring 305 and the heat conducting rod 306 is larger than that of the temperature sensing disc 301, so that the temperature change rate of the base plate 303, the first plug block 304, the pressing ring 305 and the heat conducting rod 306 is relatively slow, the temperature sensing sensitivity of the whole mechanism can be reduced, the probability of accidental starting caused by the fact that the whole mechanism is too sensitive to temperature change is reduced, and if the temperature sensing sensitivity of the whole mechanism needs to be ensured, the heat conducting rod 306 is replaced by a material which is difficult to conduct heat, such as ceramic.
