Description

Technical Field

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

[0002] The principle of fire-fighting foam monitor 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 volume after absorbing air. Foam monitors are divided into low-expansion foam monitors (foaming multiples less than 20 times), medium-expansion foam monitors (foaming multiples 20 times), and medium-expansion foam monitors (foaming multiples 20 times). 200 times), high-expansion foam cannon (foaming multiple 200 times 1000 times). Foam cannons with different magnifications are suitable for different types of fires. To achieve different firing magnifications, in addition to adjusting the foaming agent composition, the structure of the cannon and the working principle of foaming are also very different. The principle of low-magnification cannons is that when the high-speed foaming liquid jet passes through the nozzle, the Venturi effect generates negative pressure around the nozzle, sucking in air to form foam.

[0003] During the fire extinguishing process, in order to improve the fire extinguishing efficiency and ensure the safety of firefighters, the foam cannon should be placed as close to the fire point as possible, and the firefighters should be kept as far away from the fire point as possible.

[0004] The existing practice is to add a fixed base to the fire monitor. When in use, the firefighters first move the monitor and the base to the vicinity of the fire point, turn on the foam monitor and then evacuate, 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 monitor is set up and manually adjust the foam monitor, which increases the operational risks of the firefighters.

[0011] 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.

[0012] See first Figure 1 . Figure 1 The figure shows a stereoscopic diagram of an embodiment of the utility model. The low-magnification foam cannon of this embodiment includes a gun head 1, a gun body 2 and a gun mount 3, wherein a tee piece 11 is arranged between the gun head 1 and the gun body 2, so that one gun can be connected to two gun heads 1, thereby improving the efficiency of fire extinguishing. The tee piece 11 is connected to the front section 22 of the gun body through a detachable interface 21, and the interface is preferably an interface common to the gun head interface, so that the tee piece 11 is an optional component, and the gun head 1 can also be directly installed on the gun body. A bearing 23 is arranged between the front section 22 of the gun body and other parts of the gun body 2, so that the angle of the gun head 1 in the vertical direction is adjustable.

[0013] 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.

[0014] 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.

[0015] Compared with the existing low-magnification foam cannon, the utility model 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.
