PREFERRED EMBODIMENT OF THE INVENTION

[0039] In light of the figures, a preferred embodiment is described below of the fire-extinguishing device which forms the object of this invention.

[0040] As observed in FIG. 1, the fire-extinguishing device comprises a body (1) of spherical configuration comprising: a lower tank (4) of partially spherical configuration housing the extinguishing agent, which is formed by a first half-body (5) and a second half-body (5′) joined together, and an upper spray cap (7) equipped with spray nozzles (8) which are joined to the lower tank (4) completing the spherical form of the body (1).

[0041] The tank (4) has an upper face (6) whereon is found instrumentation (2) and a solenoid valve (3), also represented in FIG. 5, which determines, by automatic or manual remote actuation, the opening of the solenoid valve (3) and the consequent circulation of the extinguishing agent from the tank (4) to the spray nozzles (8) and its mass propagation from said spray nozzles (8) towards the exterior with the purpose of extinguishing the flames of a fire.

[0042] In FIG. 1 it can also be observed that the instrumentation (2) comprises an antenna (9) devised for the reception of orders, normally from a distant remote control unit commanded by the operator, a pressure transducer (11) which controls the pressure inside of the tank (4) and an electronic plate (10) connected to the antenna (9) and to the pressure transducer (11), as well as to the solenoid valve (3), wherein the electronic plate (10) records the different parameters to control such as pressure, temperature, deceleration and angular position, and acts on the solenoid valve (3) for its automatic opening once the parameters exceed predefined set-points or after receiving the order from the remote control unit.

[0043] The electronic plate (10) may integrate an accelerometer and a temperature sensor, also providing for the possibility that the electronic plate (10) is connected to another temperature sensor which may be located on the inner wall of the body (1).

[0044] Complementarily it has been provided that the device incorporates a battery (12), also represented in FIG. 1, which would feed the equipment that form part of the instrumentation (2).

[0045] In FIG. 1 it is also possible to see the different inlets and outlets of the tank (4), specifically a quick connector (15) is represented for the filling of the tank (4) with the propulsion agent, as well as observing a filling buffer (16) which allows the passage of extinguishing agent to the interior of the tank (4) and a drain valve (17) which would normally integrate a safety valve to give outlet to the tank (4) content in critical situations.

[0046] FIG. 5 shows a discharge opening (18) of the tank (4), and the mounting of the solenoid valve (3) with respect to it and the spray nozzles (8). The discharge opening (18) is internally connected to a siphon tube (19) interior to the tank (4) wherethrough the extinguishing agent will rise once the solenoid valve (3) is activated, to the spray nozzles (8) wherefrom the extinguishing agent would propagate to the outside.

[0047] The spray nozzles (8), as observed in this FIG. 5 or in FIG. 6, are radially distributed around the pole of the spray cap (7), and are connected to the solenoid valve (3) with intermediation of an upper cap (20) represented in FIG. 5.

[0048] Furthermore, in FIG. 2 it is observed how the tank (4) is formed with the half-bodies (5, 5′) joined with the intermediation of an o-ring (14), wherein the half-bodies (5, 5′) are joined together preferably by fixing means such as corresponding bolts which pass through first bores (13) defined in the walls of the half-bodies (5, 5′) and corresponding nuts.

[0049] FIG. 3 internally shows one of the half-bodies (5, 5′), specifically the first half-body (5), where it shows with greater detail the location of the first bores (13), as well as it is possible to see stiffening ribs (21) which are defined in the inner walls of the half-body (5). The stiffening ribs (21) are also observed in greater detail in FIG. 4.

[0050] In this FIG. 4 it can also be observed that on the front or perimeter wall of the first half-body (5) is located a housing (22) preferably continuous and sinusoidal which is designed to partially receive the O-ring (14) represented in FIG. 2, which on the other side would simply rest on the front or perimeter wall frontal of the second half-body (5′) in the mounting situation of both forming the tank (4).

[0051] On the other hand, in FIG. 6 it is observed that the spray cap (7) is equipped with second bores (23) designed for the passage of bolts which would thread in threaded blind bores (24), represented in FIG. 1, and defined in the upper face (6) of the tank (4), to in this way establish the mounting of the spray cap (7) on the tank (4).
