The working principle is as follows: when the fire-fighting water supply device is used, when fire fighting is carried out, the water outlet pipe 17 is aligned with the through hole 16 and the connecting pipe 13, so that fire-fighting water can enter the water outlet pipe 17 through the through hole 16, and normal water supply is guaranteed;
when the external fire-fighting water pipe and the water outlet pipe 17 need to be installed and fixed, the joint of the external fire-fighting water pipe is inserted between the first annular air bag 801 and the limiting pipe 802, then the first annular air bag 801 and the limiting pipe 802 are inflated through the inflation mechanism 9, so that the joint is clamped and fixed after the first annular air bag 801 and the limiting pipe 802 are inflated and expanded, fire-fighting water pipe joints with different specifications and sizes can be used, the applicability is stronger, the use is more convenient, when the external fire-fighting water pipe needs to be disassembled, the first annular air bag 801 and the limiting pipe 802 are exhausted through the exhaust mechanism 10, the first annular air bag 801 and the limiting pipe 802 are contracted and reset after being exhausted, the joint can be disassembled, and the disassembly of the fire-fighting water pipe is more convenient;
when the water supply quantity needs to be adjusted, the sealing plate 15 is pressed to move downwards, meanwhile, the second spring 204 is compressed, meanwhile, the sealing plate 15 is limited under the action of the limiting mechanism 3, so that the through hole 16 and the connecting pipe 13 are gradually staggered, when the water outlet pipe 17 needs to be closed, the sealing plate 15 is pushed to continuously move downwards, so that the through hole 16 and the connecting pipe 13 are completely staggered, at the moment, the end part of the water outlet pipe 17 is completely sealed, water supply is stopped, when the water outlet pipe 17 needs to be opened again, the limiting mechanism 3 is unlocked, so that the sealing plate 15 can move upwards and reset under the action of the second spring 204, the water outlet pipe 17, the through hole 16 and the connecting pipe 13 are completely aligned, so that the water supply quantity can be adjusted conveniently, meanwhile, the on-off of fire-fighting water is controlled conveniently, the connection is more convenient and rapid, the multi-port connection effect of the communication valve body 11 can be realized, and the use effect is better;
when normal water supply is carried out, the water outlet pipe 17 is completely aligned with the through hole 16 and the connecting pipe 13, the moving plate 503 is inserted into the limiting groove 703, at this time, the moving plate 503 cannot move, when the sealing plate 15 moves downwards to close the water outlet pipe 17, that is, the sealing plate 15 moves downwards to seal and block the water outlet pipe 17, at this time, the moving plate 15 moves to drive the moving block 702 to move downwards synchronously through the L-shaped plate 701, at this time, the moving plate 503 withdraws from the limiting groove 703 to lose the limiting effect on the moving plate 503, at this time, water in the connecting pipe 13 can push the piston 502 to move along the fixed pipe 501 towards the direction far away from the connecting pipe 13 under the inertia effect, and at the same time, the first spring 602 is compressed, so that the fire-fighting water can push the piston 502 to move and enter the fixed pipe 501 for temporary storage after the water outlet pipe 17 is closed, and the arrangement of the first spring 602 can play a buffering effect, so that the damage of the water hammer effect on the connecting pipe 13, the water conveying pipeline 1, the communicating valve body 11 and the like can be avoided, and the service effect and the service life of the connecting pipe 501 can be ensured;
and, when the water supply amount needs to be adjusted and the water outlet pipe 17 is closed by the plugging plate 12, the sealing plate 15 is pressed to move downwards, the movement of the sealing plate 15 drives the synchronous movement of the limiting plate 301, so that the limiting plate 301 slides on the second inclined plane 304, thereby pushing the triangular block 303 to slide in the sliding groove 401, meanwhile, the third spring 402 is compressed, when the sealing plate 15 is stopped to be pressed, the triangular block 303 is made to extend out of the sliding groove 401 under the action of the third spring 402, and the upper side wall of the limiting plate 301 is made to abut against the limiting surface 305, thereby realizing self-locking, thereby making the adjustment control more stable and reliable, and ensuring the use effect, when the water outlet pipe 17 needs to be opened, the sliding plate 403 is pushed, so that the triangular block 303 is retracted into the sliding groove 401, at this moment, the limiting surface 305 is separated from the limiting plate 301, thereby losing the limiting effect, so that the sealing plate 15 moves upwards under the action of the second spring 204 to reset, thereby opening the water outlet pipe 17.
