Technical Field

[0001] The invention relates to the technical field of fire fighting equipment, and in particular to a fire fighting water monitor with a multi-angle adjustment function. Background Art

[0002] Fire water monitor is an emergency fire-fighting auxiliary equipment used in fire-fighting engineering. Fire water monitor is a fire-fighting equipment that converts pressurized water into energy and sprays it out from the water outlet of the cannon head at a very high speed to form a water jet, thereby extinguishing the fire at a certain distance. Through the installation and use of fire water monitors, it is convenient for users to carry out fire fighting and rescue in a targeted direction, reduce the spread of fire, and thus reduce the loss of personal and economic property safety caused by fire. It has excellent social practical needs and existence value. With the rapid development of the national economy, the factors leading to fire have also increased significantly, and the fire situation has become more and more complicated. Fire water monitors can extinguish fires quickly and efficiently and prevent the spread of fires, so they play an increasingly important role in fire fighting.

[0003] Most traditional fire water cannons require firefighters to hold them in their hands to adjust and control their angles throughout the process. This is because the high pressure of the fire water cannon's spray cannon can easily cause great pressure on the hands, which consumes a lot of physical energy for firefighters and reduces the practicality of the fire water cannon. At the same time, existing fire water cannons cannot be rotated in multiple directions, which reduces the range of the fire water cannon's spraying. Summary of the invention

[0006] An injection assembly, wherein the injection assembly is fixedly connected to the filter assembly;

[0007] In which, the shell includes a shell, the top of the shell is fixedly connected with a water pipe, the inside of the shell is fixedly connected with a connecting pipe, the water pipe and the connecting pipe are located on the same vertical plane, a through hole is opened on the outside of the shell, and the injection assembly is located inside the through hole. The motor is connected to an external power supply and the motor drives the filter assembly to rotate, so that the filter assembly drives the cylinder to rotate inside the through hole, so that the rotating rod slides in the annular groove, and by setting a protrusion, when the motor stops rotating, the rotating rod and the protrusion are squeezed against each other to prevent the cylinder from rotating. Through angle limit adjustment, the injection angle of the fire water monitor can be accurately controlled within a specific range to ensure that the water flow can be accurately aimed at the fire source and improve the fire extinguishing efficiency. For example, in some places with narrow spaces or obstacles, precise angle control can prevent water from spraying to irrelevant areas and concentrate on extinguishing the fire. At the same time, reasonable angle limit can prevent the water monitor from over-rotating or exceeding the normal working range, thereby reducing the wear of mechanical parts and improving the reliability and service life of the equipment. The through hole is provided with an annular groove, which is symmetrically arranged on both sides of the through hole. The inner wall of the annular groove is symmetrically provided with protrusions. For different types of fires, such as high-rise building fires, warehouse fires, etc., the angle limit of the water monitor can be adjusted according to actual conditions to better adapt to various complex fire extinguishing needs.

With the flow of water, the rotating plate is driven to rotate, and extrusion is generated between the rotating plate and the limit block, so that the limit block moves toward the direction of the limit ring. At this time, the gap between the limit ring and the limit block becomes smaller, so that the water pressure becomes larger. The increase in water flow and water pressure makes the force of the water flow ejected stronger, which can more effectively impact the fire source and quickly extinguish the flame.

After the reaction force is buffered, the water The shaking amplitude of the cannon is significantly reduced, which helps to maintain the stability of the water cannon and avoid affecting the fire extinguishing effect due to excessive shaking. It can also extend the service life of the water cannon by reducing this impact. The middle part of the sphere is fixedly connected with a rotating shaft, which runs through the sphere. The rotating shaft is rotatably connected to the inside of the shell, and one end of the rotating shaft is fixedly connected to the output end of the motor.

For example, in some places with narrow space or obstacles, precise angle control can prevent the water flow from spraying to irrelevant areas and concentrate on extinguishing the fire source. At the same time, reasonable angle limit can prevent the water monitor from over-rotating or exceeding the normal working range, thereby reducing the wear of mechanical parts and improving the reliability and service life of the equipment.

[0014] 2. The fire-fighting water monitor with multi-angle adjustment function generates extrusion between the rotating plate and the limit block, so that the limit block moves toward the direction of the limit ring.

[0016] 4. After the fire-fighting water cannon with multi-angle adjustment function is buffered by the reaction force, the shaking amplitude of the water cannon is significantly reduced, which helps to maintain the stability of the water cannon and avoid affecting the fire-fighting effect due to excessive shaking. It can also extend the service life of the water cannon by reducing such impact.

[0017] 5. The fire-fighting water monitor with multi-angle adjustment function can accurately control the motion trajectory of the rotating component to ensure that the water monitor can accurately reach the predetermined position during the rotation process, avoiding misalignment of the outer ring and the inner ring.

The increase in water flow and water pressure makes the water jet more powerful, which can more effectively impact the fire source and quickly extinguish the flame.

[0038] After water is sprayed out from the cylinder 71, the device itself will receive a reaction force, so that the cylinder 71 exerts force on the sphere 41, and the sphere 41 moves away from the cylinder 71.
