Described shower nozzle is adjustable shower nozzle (shown in the 4-7-2 among Fig. 1) or Fan spray head (as shown in figure 10) or direct projection shower nozzle (as shown in Figure 9).
Complete machine structure adopts backpack, operates simple and easy.Simultaneously, when electric quantity of power supply is not enough, adopt manual mode, realize one-machine-multi-function, the mode of first-selected electronic water outlet under the situation that electricity is arranged.
During electrodynamic pump water, connect power switch, given motor 13 power supplies of membrane pump 2 by battery 1, electric machine main shaft 21 rotations, drive cam 20 and rotate, 20 drive diaphragm movement seat 23 pumps, and makes diaphragm 18 back and forth be out of shape the variation that causes cavity volume; When diaphragm movement seat 23 moves downward, last diaphragm 18 is recessed, it is big that the volume of last cavity volume 17-1 between membrane pump loam cake 17 and the last diaphragm 18 becomes, last cavity volume internal pressure reduces, water from water pocket 3 to water inlet 26-1 and intake antrum 26 push enterprising water one-way valve 27 open and be inhaled into the cavity volume 17-1 through last intake tunnel 17-2; Simultaneously, lower diaphragm plate sheet 18 is recessed, the volume of following cavity volume 24-1 between membrane pump lower cover 24 and the lower diaphragm plate sheet 18 diminishes, following cavity volume internal pressure increases, water is pushed out water one-way valve 29 open through exhalant canal 24-3 down in the following cavity volume 24-1 and is entered water chamber 31 and be pumped out by delivery port 31-1, finishes once suction and pump water conservancy project work; When diaphragm movement seat 23 moves upward, last diaphragm 18 epireliefs, volume that make to go up cavity volume 17-1 diminishes, and last cavity volume internal pressure increase before had been drawn into water among the cavity volume 17-1 and has pushed upper water-out check valve 29 open through upper water-out passage 17-3 and enter water chamber 31 and be pumped out by delivery port 31-1; Simultaneously, lower diaphragm plate sheet 18 epireliefs, it is big that the volume of following cavity volume 24-1 becomes, following cavity volume internal pressure reduces, water from water pocket 3 to water inlet 26-1 and intake antrum 26 push down water inlet check valve 27 open and be inhaled into down the cavity volume 24-1 through intake tunnel 24-2 down, finish suction again and pump water conservancy project and do, the Inlet and outlet water work of membrane pump 2 has just been finished in motion and so forth.The water that pumps enters hydraulic giant 4 by rubber tube 12 again, again by the adjustable shower nozzle ejection of hydraulic giant, thereby realizes fire-extinguishing function concurrently.
Membrane pump pressure limiting device 15 can effectively protect pump to prevent from damaging, and when the operating pressure of pump surpasses maximum pressure, pump 2 is quit work.When excessive as the pressure in the water chamber 31; the pressure limiting piston 32 that water in the pressure limiting hole then promotes pressure limiting system 15 moves backward; promote fine motion normally closed switch 34, two contacts of fine motion normally closed switch 34 are disconnected, the motor 13 of pump 2 is quit work; pump 2 also quits work; it is not fragile to make it safety, thereby reaches the effect of protection and pressure limiting, has guaranteed the durability of pump; after fault was got rid of, two contacts of fine motion normally closed switch 34 then recovered to connect automatically.
If battery 1 can't give motor 13 power supplies, can adopt the manual work mode to put out a fire, turn off power switch earlier, pull out the quick male joint 8 of hydraulic giant 4 then, insert the quick male joint 8 of hydraulic giant 4 at quick female joint 9 places of water pocket 3 and can adopt the manual work mode to put out a fire.The operation principle of hand is to move back and forth by hydraulic giant piston rod 4-4 to realize the pulsating pump water function, when hydraulic giant piston rod 4-4 moves upward, volume between hydraulic giant sleeve pipe 4-2 and the hydraulic giant piston rod 4-4 increases, and pressure reduces, and water is pushed hydraulic giant water inlet check valve 4-1 open and is inhaled in the rifle body; When hydraulic giant piston rod 4-4 moved downward, the volume between hydraulic giant sleeve pipe 4-2 and the hydraulic giant piston rod 4-4 reduced, and pressure increases, and water is pushed hydraulic giant open and gone out water one-way valve 4-3, and water is from shower nozzle 4-7 ejection, thus the work of realization hand sprinkling fire.
By changing Water-syringe shospay nozzle, can realize multiple jeting effect, the 4-7-2 among Fig. 1 is adjustable shower nozzle, can realize atomizing effect; As change direct projection shower nozzle shown in Figure 9 into, can realize the direct projection water column; As change Fan spray head shown in Figure 10 into, can realize fan-shaped water column.Can suitably change Water-syringe shospay nozzle according to different fire intensity of a fire situations.
