High-speed aerial equipment

Technical field

The technical solution relates to high-speed air equipment intended primarily for use in the field of fire extinguishing technology, but also applicable in the field of communal cleaning technology and also in the field of police repression technology.

BACKGROUND OF THE INVENTION

In the field of fire-fighting technology, various types of so-called water jets, used as part of superstructures on lorries known as tank automobile syringes, are used in particular to extinguish larger fires. In these water jets, water or water in combination with other available extinguishing agents is used as an extinguisher. The use of water or a combination of water, in particular with foam extinguishing agents, in these devices is well proven for extinguishing. However, the use of water or a combination of water with other types of extinguishing agents in these so-called water nozzles or water cannons for other purposes is often problematic in practice.

In addition to extinguishing purposes, superstructures of vehicles with water jets are also used, as necessary, as a cleaning facility in the municipal area and also as a repressive police vehicle for suppressing street extremist riots, where they operate with a rapid flow of water. In particular, this police use usually leads to increased damage by flooding of street objects and can also lead to serious injuries of demonstrators and consequent recovery of damages to the interveners.

Tzv. water jet or water cannon due to its design acts in extinguishing, communal use and police use from a greater distance, and for this reason its efficiency and especially the accuracy of the intervention decreases.

The essence of the technical solution

The above-mentioned drawbacks of the above-mentioned solutions are largely overcome by the high-speed, streamlined airway device with angled transitions of the pipe diameter according to the present invention, which consists in that the high-speed, streamlined airway device with angled crossings of the pipe diameter is formed by an axial fan. housed in a cylindrical fan casing connected to a rigid outer frame to which a suction portion of a cylindrical high-speed air device is rigidly attached on one side and a conical-shaped or conical-shaped outlet outlet portion firmly connected thereto when the rigid outer frame is further coupled to a device for vertically and horizontally tilting the whole of the high-speed air device, and into the space of the exit part t the at least one inlet, extinguishing pipe for extinguishing the extinguishing agent is provided with at least one connected extinguishing reservoir, and in the preferred embodiment the extinguishing reservoir is further provided with at least one high pressure pump for pressurizing the extinguishing agent from the extinguishing reservoir to the outlet portions of high-speed air equipment with kinked pipe diameter transitions when an air source with subsequently mixed extinguishant and / or separate air to form an air wall obtaining its high velocity at the outlet of the high-speed air equipment by axial fan operation and outlet shape is taken from the outside the suction part of the high-speed air-handling device, with the high-speed air-shaped jet device with angled pipe diameter transitions, housed in a rigid frame with a connected hinge for vertical and horizontal tilting, it is located on an automobile chassis or on another mobile chassis, preferably equipped with a remote control, or on a stationary device, in particular on a ramp, also preferably equipped with a remote control of all functions. In another preferred embodiment, the outlet portion of the high-speed air device at its front portion is further provided with a connection element for connection

Special working attachments, in particular flexible tubes or hoses for carrying out fire-fighting work inside buildings, cleaning attachments of various shapes for communal use and the like.

The high velocity jet-shaped airway device with angled pipe diameter crossings according to the present invention is essentially a large-volume fire extinguisher whose propellant is air drawn from the outside, unlike conventional extinguishers where air or other propellant for extinguishing media is placed together With extinguishing agents in the storage tank, extinguishing agents of varying consistency, including powder, foam or gas, can be freely added to this air. Individual extinguishing agents can be mixed as required in the outlet section of high-speed jet-stream air equipment with angled pipe diameter transitions. The control and adjustment of the equipment, including the adjustment of the mixing ratios of the individual extinguishing agents with air or extinguishing agents, can be done manually at the equipment or from the driver's cab of the vehicle on which the equipment is stored, or can be equipped with a remote control of all its functions.

The high air velocity achieved in the conical duct, which removes oxygen from the extinguishing medium and covers the extinguishing area at high speed, combined with suitably used extinguishing agents, is the main extinguishing effect of this high-speed aerial equipment as a fire extinguisher. The use of air as an extinguishing agent significantly reduces the subsequent damage caused by fire fighting. Air reaching the speed of up to 150km / h, ie over 40 m / s creates an air wall. It is practically impossible to throw objects over such a wall. Strong

2ΰ air, approaching the strength of the hurricane, will not allow persons to approach the device. This equipment will enable effective fire extinguishing, municipal cleaning and last but not least repressive street riots.
