Description

Technical Field

[0001] The utility model relates to a fire-fighting appliance, and more specifically to a remote-controlled foam cannon for fire-fighting. Background Art

[0002] The principle of fire-fighting foam cannon is to mix fire-fighting water of a certain pressure with foam liquid through a foam proportion mixing device to form a foam mixture of a certain proportion, which is then sprayed out through a nozzle to form air foam to achieve the fire extinguishing effect. The foam mixture expands in multiples after absorbing air. Foam cannons are divided into blizzard foam cannons (foaming multiples less than 20 times), medium foam cannons (foaming multiples ), high-expansion foam cannon (foaming multiples ). Foam cannons with different firing multiples are suitable for different types of fires. To achieve different firing multiples, in addition to adjusting the foaming agent composition, the structure of the cannon and the working principle of foaming are also very different.

[0003] In the prior art, the function of foam monitors is relatively simple, and multiple foam monitors are required to deal with different fires. In addition, in the process of extinguishing a fire, in order to improve the efficiency of firefighting and ensure the safety of firefighters, the foam monitor should be placed as close to the fire point as possible, while the firefighters should be kept as far away from the fire point as possible.

[0004] The existing practice is to install a fixed base for the foam cannon. When in use, the firefighters first move the cannon and the base to the vicinity of the fire point, and then evacuate after the foam cannon is turned on, thereby preventing the firefighters from being close to the fire point for a long time. However, when the spraying angle needs to be adjusted, the firefighters still need to go to the place where the foam cannon is set up and manually adjust the foam cannon, which increases the operational risks of the firefighters.

[0007] Preferably, in the above remote-controlled blizzard foam cannon, the cannon head is connected to the front section of the cannon body via a detachable interface.

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figures 1 to 3 These are three-dimensional diagrams of one implementation mode of the utility model under three different viewing angles. DETAILED DESCRIPTION

[0013] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0014] See first Figure 1 . Figure 1 The 3D view of an embodiment of the utility model is shown. The blizzard foam cannon of this embodiment includes a cannon head 1, a cannon body 2 and a cannon base 3. The cannon head 1 is connected to the front section 22 of the cannon body through a detachable interface 21. A bearing 23 is arranged between the front section 22 of the cannon body and other parts of the cannon body 2 (see FIG. Figure 2 ), so that the angle of the gun head 1 in the vertical direction can be adjusted.

[0015] The gun head 1 includes an outer cover 11, a medium-magnification gun nozzle 12, and a low-magnification gun nozzle 13. The low-magnification gun nozzle 13 is longer than the medium-magnification gun nozzle 2, and the outer cover 11 is longer than the low-magnification gun nozzle. In this example, in order to increase the amount of foam, two medium-magnification gun nozzles are provided. The foaming liquid sprayed by the medium-magnification gun nozzle 13 has a small kinetic energy and a short range, but the foaming liquid sprayed by the low-magnification gun nozzle 12 has a greater kinetic energy, which can bring the foam formed by the medium-magnification gun 13 to a farther range, thereby greatly overcoming the defect in range. Preferably, a foaming net 14 is provided in the outer cover 11 (see Figure 3 ). The foaming liquid sprayed from the medium-multiplication nozzle 12 passes through the foaming net and is mixed with more air, thereby producing a larger foaming multiple.

[0016] The bearing 23 is connected to a hydraulic adjustment mechanism 24, which is connected to a remote control box 25. A stepper motor, a remote control signal receiver and a stepper motor control circuit are arranged in the remote control box 25. The stepper motor, the remote control signal receiver and the control circuit between the two are prior art, so they are not described in detail. The remote control signal receiver is responsible for receiving remote control information instructions, and controls the start, stop and rotation direction of the motor through the control circuit, so that the firefighter can remotely control the operation of the stepper motor through the remote controller, and further control the elevation angle of the gun head 1 in the vertical direction through the hydraulic adjustment mechanism 24.

[0017] In order to enhance the robustness of the fire monitor, preferably, the adjustment mechanism 24 also provides a manual knob 26, and the extension and retraction of the hydraulic rod of the adjustment mechanism is controlled by rotating the knob, thereby manually controlling the elevation angle of the gun head 1.

[0018] Compared with the existing blizzard foam cannon, the utility model combines the advantages of medium-magnification cannons and low-magnification cannons, expands the application scenarios, and can remotely adjust the elevation angle of the foam cannon, thereby reducing the necessity for firefighters to operate near the fire point and reducing the risk of firefighting operations.

[0019] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
