Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting equipment, and in particular relates to a main body for a mobile fire-fighting gun. Background Art

[0002] Fire monitors are crucial firefighting equipment today. They are suitable for large locations such as petrochemical plants, storage tank farms, hangars, warehouses, and port terminals, making them ideal on-board firefighting equipment for fire trucks. However, traditional fire monitors lack the ability to adjust the angle and direction of the cannon head, and the barrel's center of gravity faces forward, making it prone to tipping. Utility Model Content

[0003] The purpose of the utility model is to provide a main body for a mobile fire-fighting gun, so as to solve the above-mentioned problems existing in the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A main body for a mobile fire-fighting gun, comprising a water collecting seat and a U-shaped bend, the U-shaped bend being arranged on the top of the water collecting seat and connected to the water collecting seat, at least one water inlet being provided on the water collecting seat, connecting flanges being formed at both ends of the U-shaped bend, the connecting flange at the lower end of the U-shaped bend being connected to a first rotating outer sleeve, a first worm gear inner sleeve being provided inside the first rotating outer sleeve, a lower end of the first worm gear inner sleeve being fixedly connected to the water collecting seat, the first rotating outer sleeve being rotatably sleeved on the first worm gear inner sleeve, a first rotary drive device being provided on the first rotating outer sleeve, and the output end of the first rotary drive device being matched with the worm gear inner sleeve; a second worm gear inner sleeve being connected to the second worm gear inner sleeve at the connecting flange at the other end of the U-shaped bend, a second rotating outer sleeve being provided with a second rotating outer sleeve on the outer rotating sleeve, a second rotary drive device being provided on the second rotating outer sleeve, and the second rotating outer sleeve being connected to a gun head.

[0006] The working process and principle of the above structure are as follows:

[0007] The setting of the U-shaped bend pipe makes the center of gravity downward after the water pressure rushes out, and the blister fire fighting equipment is not easy to tip over. At the same time, the setting of the water collecting seat can connect the water pipe to the water inlet of the water collecting seat according to the water demand, so as to realize water supply. When it is necessary to adjust the direction of the fire cannon, the first rotary drive device cooperates with the first worm gear inner sleeve to drive the first rotary outer sleeve to rotate, thereby realizing the rotation of the U-shaped bend pipe and achieving the purpose of adjusting the direction. When it is necessary to adjust the angle of the gun head, it is only necessary to drive the second rotary outer sleeve to rotate on the second worm gear inner sleeve through the second rotary drive device, thereby adjusting the angle of the gun head and facilitating the adjustment of the water flow output angle, thereby improving the flexibility of the fire fighting mobile cannon.

[0008] Furthermore, the water collection seat is provided with two water inlets, and the two water inlets are arranged in a V shape on the side of the water collection seat.

[0009] The setting of two water inlets can provide greater water source power.

[0010] Furthermore, a handle seat is provided at the top of the U-shaped bent tube, and a handle is provided on the handle seat.

[0011] The setting of the handle seat and the handle makes it easy to manually lift and move the equipment.

[0012] Furthermore, a pressure gauge is provided in the middle of the handle base, and an electric control device is provided on one side of the handle base.

[0013] The setting of the pressure gauge can detect and understand the water pressure, and the electronic control device can control the operation of the electronic equipment on the water cannon equipment.

[0014] Furthermore, the structures of the first rotating outer sleeve and the second rotating outer sleeve, the first worm gear inner sleeve and the second worm gear inner sleeve, and the first rotation drive device and the second rotation drive device are the same; a number of rolling steel balls are arranged between the first rotating outer sleeve and the first worm gear inner sleeve, and a Y-type sealing ring is arranged at the upper end between the first rotating outer sleeve and the first worm gear inner sleeve, and an O-type sealing ring is arranged at the contact surface between the first rotating outer sleeve and the U-shaped bend pipe and the contact surface between the first worm gear inner sleeve and the water collecting seat. The first rotation drive device includes a drive motor, a motor mounting plate and a drive shell, and the drive shell and the motor mounting plate are both arranged on the first rotating outer sleeve, the drive motor is fixed on the motor mounting plate and the output end of the drive motor extends into the drive shell and is coaxially connected with a worm, the worm is meshed with the first worm gear inner sleeve, and the worm is rotatably arranged in the drive shell. The internal structure of the first rotation drive device and the internal structure of the second rotation drive device are also the same in installation position and structure.

[0015] By setting the rolling steel balls, the rotational friction between the first rotating outer sleeve and the first worm gear inner sleeve can be reduced. The Y-type sealing ring can prevent water leakage. The O-type sealing ring is also used to ensure the sealing between the first worm gear inner sleeve and the water collecting seat and the first rotating outer sleeve and the U-shaped bend pipe. The worm is driven by the driving motor to rotate, and the worm cooperates with the first worm gear inner sleeve to realize the rotation drive of the first rotating outer sleeve, driving the U-shaped bend pipe to rotate. According to the same principle, the second rotation drive device drives the gun head angle adjustment through the second rotating outer sleeve.

[0016] Furthermore, the worm shaft extends out of the drive housing at one end away from the drive motor and is coaxially connected to a knob.

[0017] By setting the knob, the worm can be manually driven to rotate, thereby adjusting the direction of the U-shaped bend and changing the angle of the gun head.

[0018] Furthermore, the two ends of the U-shaped elbow are staggered.

[0019] The two ends of the U-shaped bend are staggered to help buffer the water flow and move the center of gravity downward.

[0020] Furthermore, an upper bend pipe is provided between the second rotating outer sleeve and the gun head, the upper bend pipe is connected to a transition rectifier seat, and the transition rectifier seat is connected to the gun head.

[0021] The upper bend makes it easy to connect the nozzle, and the transition rectifying seat can play a preliminary role in rectifying the water flow so that it can be better sprayed out from the nozzle.

[0022] Furthermore, the water inlet includes a water inlet seat, one end of which is connected to a water hose interface, and the other end of which is hinged to a one-way valve core plate.

[0023] The setting of the water inlet seat facilitates the installation of the water hose interface and the setting of the one-way valve core plate, which helps to connect the water hose and ensure one-way water inlet.

[0024] Beneficial effect: The utility model uses the setting of the U-shaped bend pipe, so that after the water pressure rushes out, the center of gravity is downward, and the water bubble fire fighting equipment is not easy to overturn. At the same time, the setting of the water collecting seat can connect the water pipe to the water inlet of the water collecting seat according to the water volume demand, so as to realize water supply. When it is necessary to adjust the direction of the fire cannon, the first rotary drive device cooperates with the first worm gear inner sleeve to drive the first rotary outer sleeve to rotate, thereby realizing the rotation of the U-shaped bend pipe and achieving the purpose of adjusting the direction. When it is necessary to adjust the angle of the gun head, it is only necessary to drive the second rotary outer sleeve to rotate on the second worm gear inner sleeve through the second rotary drive device, so as to adjust the angle of the gun head and facilitate the adjustment of the water flow output angle, thereby improving the flexibility of the fire mobile cannon.
