Detailed Description

Referring to fig. 1-3, a novel fire-fighting lance comprises a through main pipe (1), a water-shaped adjustable nozzle (101), a water quantity adjusting ring (3), a holding handle (4), a main switch lever (5), a shoulder block (7) and a pipeline interface (8);

the jet-type water-cooled water heater is characterized in that a watery adjustable nozzle (101) is installed on the rightmost side of the run-through main pipe (1), a water quantity adjusting ring (3) is installed on the right side of the middle of the run-through main pipe (1), a holding handle (4) is installed in the middle of the run-through main pipe (1), a main switch rod (5) is inserted in the middle of the holding handle (4), a shoulder supporting block (7) is installed above the left side of the middle of the run-through main pipe (1), and a pipeline connector (8) is installed on the leftmost side of the run-through main pipe (1);

the right side outer wall that link up and be responsible for (1) is installed auxiliary assembly, the positive surface left side embedding that link up and be responsible for (1) is installed siphon pressure boost interface (6).

In the embodiment, the auxiliary assembly comprises a light-compensating ring (2), an LED lamp (201) and a lens (202), the light-compensating ring (2) is arranged in the middle of the auxiliary assembly, the LED lamp (201) is arranged inside the light-compensating ring (2), the lens (202) is nested outside the LED lamp (201), and the lens 202 arranged outside the LED lamp (201) can prevent the LED lamp (201) from diffusing when bright light is generated to irradiate on a fire extinguishing point, so that the irradiation distance of the light is increased.

In this embodiment, the middle parts of the LED lamps (201) surrounding the light-compensating ring (2) are arranged in a circular ring shape, the number of the LED lamps (201) is 16-20, and the plurality of LED lamps (201) can irradiate on the fire-extinguishing point to perform light-compensating illumination on the fire-extinguishing point when being electrified to generate bright light.

In the embodiment, an inner pipe (9) is installed inside the through main pipe (1), and a drainage groove is formed in the middle opening of the inner pipe (9), so that water flowing in the through main pipe (1) can pass through the drainage groove in the inner pipe (9) to be discharged from the water-shaped adjustable nozzle 101.

In this embodiment, the left and right ends of water drainage tank all is the little hourglass hopper-shaped setting of the big inboard in outside in inner tube (9), the vertical area at water drainage tank middle part is less than the vertical area of cutting of left and right ends, and when water flows in inner tube 9, the velocity of flow of water can rise because the cross sectional area of inner tube 9 reduces, and high-speed fluid is being responsible for 1 inside formation negative pressure in running through to the realization carries out the automatic attraction to the foam liquid through siphon pressure boost interface 6 and the hose in its outside.

Wherein, the main function of the shoulder block 7 is to prevent the fire-fighting lance from being difficult to hold due to too large thrust.

The working principle is as follows: when water flows in the through main pipe 1, the speed of the liquid rises due to the reduction of the cross section area of the inner pipe 9, and the high-speed fluid formed by the narrow opening forms negative pressure in the through main pipe 1, so that the foam concentrate is sucked through the siphon pressurizing connector 6 and the hose, mixed with the water after entering the through main pipe 1 and then sprayed through the water-shaped adjustable nozzle 101;

when the LED lamp 201 of the light compensation ring 2 is powered on, bright light is generated to irradiate a fire extinguishing point.
