[0015] IMPLEMENTATION OF UTILITY MODEL

[0016] The possible implementations of the claimed technical solutions described in this section are presented on non-limiting examples of legal protection, in relation to specific embodiments of the claimed technical solution, which in all their aspects are assumed to be illustrative and not restrictive. Alternative options for implementing the claimed technical solution, which do not go beyond the scope of legal protection, are obvious to specialists in the field with the usual qualifications for which this technical solution is designed.

[0017] A suitable gas fire extinguishing device is any one of: described in US 2017036048 A, the materials of which are hereby incorporated herein by reference; described in the patent of the Russian Federation No. 2667881, the materials of which, according to the application of the Russian Federation 2017135603 dated July 20, 2017, are thus included in this description by reference; as well as any other similar device, the principle of operation of which is based on the use of a shut-off device with a piercing needle to pierce the membrane of a cylinder with a gas fire extinguishing agent. An exemplary embodiment of such a gas fire extinguishing apparatus 100 is shown in FIG. 1.

[0018] As shown in FIG. 1 as a whole, the fire extinguishing device is a container 1 filled with a gaseous fire extinguishing agent, with a lock nut 2, the lock nut 2 being connected to the outlet of the container and containing a locking element that holds the extinguishing agent inside the container under pressure; and a lock-start device 300, the lock-start device 300 consists of a body 31 for the pusher 4, on the one hand connected to the lock nut 2, and on the other side connected to the atomizer 32; housing 31 for the pusher 4 is a hollow rod with a hollow mounting base 33, in the lower part of the rod and partially in the mounting hollow base 33, coaxial grooves 34 for the mounting pin 5 are made, while inside the rod a pusher 4 spring-loaded by a spring 37 is fixed, containing a mounting base 41 and an elongated truncated cylindrical tip 42, on two surfaces of which flats 421, 422 are made, and in the mounting base 41, a through hole 43 is made, coaxial with the mentioned grooves 34, through which, by means of the mounting pin 5, the pusher 4 is fixed in a spring-loaded position through the mentioned grooves 34 , moreover, the atomizer 32 is a hollow cylindrical cap, strung on the body 31 for the pusher 4 and fixed through the holes 35 in its lower part by means of the mentioned pin 5 through the mentioned grooves 34 and the hole 43, while in the upper part of the atomizer there is a cavity for placing the lock 6, while in the upper part of the atomizer on the sides there are spray holes 36, and the lock 6 forms a stop for the mentioned rod and prevents the spring from expanding, and the destruction of the lock 6 leads to the expansion of the spring, and the expansion of the spring leads to the movement of the said pin 5 along the mentioned grooves 34 in the direction of the lock nut 2, and said pusher 4 is placed in such a way that, when the pin 5 is moved, it moves in the direction of the lock nut 2, pierces the mentioned locking element and releases the extinguishing agent. At the same time, said lock 6 is a thermal lock, that is, as a rule, a glass flask containing a thermosensitive liquid, which, when a certain temperature is reached, expands, creating excess pressure inside the flask and leading to its destruction, or may be any other known (or created in the future) and a usable element capable of destruction, for example, but not limited to, when heated to a certain temperature, or in response to the detonation of an explosive inside the lock, or when the lock is mechanically acted upon, for example, but not limited to, when the lock is kinetically . Preferably, without limitation, the operating temperature of the lock 6 ranges from 57 to 93 +/- 3 degrees Celsius. At the same time, it should be obvious to a specialist in this field of technology, who has ordinary knowledge, for whom the claimed technical solution is designed, that another device can be used as a lock 6, for example, a metal rod or strip, the elasticity or fragility of which increases when heated. up to certain temperatures, which will also lead to the termination of their action as a stop for the spring 37. Alternatively, the pusher 4 can be made in the form of a conventional hollow needle with a through hole for the exit of the gas fire extinguishing agent. Such a plunger is known from the prior art and, accordingly, will not be described in further detail.

[0019] Preferably, but not limited to, the container 1 may be a cylinder or any other container containing a pressurized gas extinguishing agent. At the same time, it is preferable that the volume of the container 10 be provided from 0.08 to 0.67 l, the overall dimensions of the container 1 were, respectively, from 210 to 440 mm in length and from 35 to 60 mm in width, and the container 1 itself could accommodate, respectively, from 60 to 500 g of fire extinguishing agent. Such characteristics of the container 1 make it possible to ensure sufficient manufacturability and safety of operation, since, in combination with other parameters of the device, the gas fire extinguishing agent is safely retained inside the container 1. The gas fire extinguishing agent in this case is any gas fire extinguishing agent known from the prior art, for the exit of which a propellant is required, preferably carbon dioxide.

[0020] Preferably, but not limited to, the closure element may be, but not limited to, a metal membrane or a membrane of any other material capable of withstanding an operating pressure of 250 bar at 20 degrees Celsius. In this case, it is preferable, if the membrane is metallic, that its thickness is not less than 0.2 mm and not more than 1 mm. A person of ordinary skill in the art, for whom this technical solution is intended, should be obvious that if the membrane is made of a different material, it may need to have a different thickness, but still not lose the ability to withstand the specified operating pressure, and the pusher 4 should be able to break through such a membrane.

[0021] Preferably, without being limited, the grooves 34, in which the pin 5 moves, are made symmetrically to each other in the walls of the housing 31 for the pusher 4. This allows the pusher 4 to be placed along the axis of the container outlet and eliminates the possibility of it jamming or breaking through the locking element under wrong angle. Preferably, without being limited, the length of the grooves 34 in which the pin 5 moves, the length of the expansion of the spring 37, which ensures the movement of the pusher 4, approximately corresponds to half the length of the lock 6, which allows the pusher 4 to travel sufficient to reliably break through the locking element, but not block the spray holes 36 in the actuated state of the shut-off and trigger device 3. The pusher 4 contains a mounting base 41 and an elongated truncated cylindrical tip 42, on two surfaces of which flats 421, 422 are made, and in the mounting base 41, a through hole 43 is made, coaxial with the mentioned grooves 34, through which, by means of a mounting pin 5, the pusher 4 is fixed in a spring-loaded position through the mentioned grooves 34. Through the same pin 5, the pusher 4, the body 31 for the pusher 4 and the atomizer 32 are fixed relative to each other. Preferably, without being limited, the total area the cross-sections of the flats 421, 422 are selected greater than or at least equal to the cross-sectional area of the passage channel of the classic pusher, known from patent application US 2017036048 A, the materials of which are incorporated into this description by reference; or known from the patent of the Russian Federation No. 2667881, the materials of which according to the application of the Russian Federation 2017135603 dated 07/20/2017, are thus included in this description by reference. However, mainly it should be assumed that the total cross-sectional area of the flats 421, 422 is chosen such as to ensure the free exit of the fire extinguishing agent from the outlet along the flats 421, 422 in the direction of the inner walls of the spray cap 32 in the direction of the holes 36; that is, it should be mainly assumed that the radii of the flats 421, 422 are selected significantly less than the distance between the inner wall of the atomizer cap 32 and the outer wall of the housing 31 for the pusher 4. In this case, under the cross sections of the flats 421, 422, under their radii, are understood the values , calculated in relation to the cylinder in which these flats 421, 422 are performed. In this case, the pusher 4 is preferably, without being limited, made of a cylindrical stainless steel rod by cutting off a cylinder of the required length from it and then in any order of performing the steps: performing a truncation from one of the ends, making a transverse hole 43 for the pin 5, performing from two of sides of flats 421, 422; which is a simpler and faster manufacturing method compared to the manufacturing process of a classic hollow needle pusher. At the same time, without limitation, a pusher 4 can also be provided, made of a cylindrical stainless steel rod by cutting off a cylinder of the required length from it and then in any order of performing the steps: partial or complete milling of the cylinder to obtain a workpiece for the pusher in the form of a parallelepiped, performing truncation of one of the ends of the parallelepiped, making a transverse hole 43 for the pin 5 from the other end; which is a simpler and faster manufacturing method compared to the manufacturing process of a classic hollow needle pusher, but more complicated than the above-described process for manufacturing a pusher with flats 421, 422, although it allows you to get a more efficient pusher in terms of overall dimensions, half-width dimensions the parallelepiped of which are preferably chosen to be substantially smaller compared to the distances between the inner wall of the atomizer cap 32 and the outer wall of the body 31 for the pusher 4. However, without being limited, if a suitable rectangular bar is provided, the manufacturing method can be reduced to cutting off the parallelepiped of the required length, making a transverse hole 43 for the pin 5 at one end and truncating the parallelepiped from the other end, which will further simplify and speed up the manufacturing process of the pusher 4. In the absence of a rectangular bar of the required dimensions, a milling step can also be provided to ensure the required dimensions of the parallelepiped. It should be obvious to a person of ordinary skill in the art, for whom this utility model is designed, that the pusher 4 can be made of the shapes and sizes described above from any other suitable material, the choice of which should mainly be based on that such a material should have a high melting point, as well as high hardness and low brittleness.

[0022] Preferably, but not limited to, the atomizer cap 32 may include a plurality of spray holes 36. In the case of two spray holes 36, it is preferred that such holes 36 be placed symmetrically to each other. In the case of three spray holes 36, it is preferable that such holes 36 were placed at an angle of 120 degrees with respect to each other. In the case of four spray holes 36, it is preferable that such holes 36 be placed at an angle of 90 degrees with respect to each other, and so on. The lock 6, for example, without being limited, is a device known from the prior art, which is a glass flask with a substance, when heated, the glass bursts and the lock 6 is destroyed, however, a specialist in this field of technology with ordinary knowledge, for whom the claimed technical solution is designed, it should be obvious that the operability of the device does not depend on the method of destruction of the lock 6, which can thus be destroyed forcibly. Preferably, without limitation, the operating temperature of the lock 6 ranges from 57 to 93 +/- 3 degrees Celsius. At the same time, it should be obvious to a specialist in this field of technology, who has ordinary knowledge, for whom the claimed technical solution is designed, that another device can be used as a lock 6, for example, a metal rod or strip, the elasticity or fragility of which increases when heated. to certain temperatures, which will also lead to the termination of their action as a stop for the spring 37.

[0023] In order to be able to control the pressure inside the container 1, it can be equipped with the claimed adapter 200. The adapter 200 for the gas device 100 for extinguishing a fire, preferably, without being limited, is configured to be connected to the outlet of the container 1 for a gas fire extinguishing agent, contains a mating with said outlet, a passage channel 7 containing a branch 71 connected to a fitting 72 with a check valve 721, and the outlet of the said passage channel is equipped with a locking element 73, for example, without being limited, similar to that described earlier, or representing the previously described lock nut 2 with a locking an element similar or similar to the locking element 73, and is configured to be connected to the shut-off and starting device 3 of the gas device 100 for extinguishing a fire. Preferably, but not limited to, at the junction of the branch 71 and fitting 72, the check valve 721 is spring-loaded by the spring 722, which improves the reliability of filling the container 1, preventing accidental release of fire extinguishing agent or gas. Preferably, but not limited to, check valve 721 is provided with a seal 723, such as, but not limited to, an o-ring. Preferably, without limitation, the check valve 721 has a cone-shaped part that extends into the cavity of the fitting 72. The fitting 72 is configured to be connected to a pressure control device 8, for example, but not limited to, a pressure gauge or other unified device, such as a pressure indicator, an electrical contact relay pressure, analog pressure sensor and similar devices. This configuration of the adapter allows you to alternately fill the container 1 with different gases and/or fire extinguishing agents, for example, without limitation, it allows you to fill the container 1 first with a gas fire extinguishing agent - freon or a gas fire extinguishing agent based on fluoroketone, for example, without limitation, such as a gas fire extinguishing agent 3M ™ Novec™, and after the propellant - nitrogen. In addition, the use of the inventive adapter also allows the replacement of the extinguishing agent and/or gas in the container without the need to disconnect the key elements of the fire extinguishing device - it is enough to remove the connected pressure control device, after which the fitting 72 can be used as a drain and filling valve. The possibility of connecting a pressure control device allows you to constantly monitor the performance of the gas fire extinguishing device 100.

[0024] The claimed gas device 100 for extinguishing a fire is preferably, without limitation, placed in a protected volume to provide a method of protection against fire or a method of extinguishing a fire, in which the said device is activated either upon reaching the threshold temperature at which the lock 6 is activated, or forcibly by destroying the lock 6 by heating it, and/or detonating it, and/or by kinetic action in response to a signal from the control panel of the fire system, which, without being limited, is any fire system known from the prior art, which, accordingly, is not further detailed described. Preferably, without being limited, the volume to be protected is some small-sized closed volume, such as, for example, without limitation, a closed distribution and / or power and / or input mounting board, a stationary access and / or floor electrical panel, internal and /or an outdoor electrical cabinet, a mounted and/or built-in electrical panel and/or an electrical box, a mounted and/or built-in control panel, a server rack with equipment, a telecommunications rack with equipment, a vehicle engine compartment, a space for placing electric energy batteries in a vehicle, the cargo compartment of the vehicle and the like volumes. In this case, without being limited, it should be mainly assumed that the volume to be protected is predominantly a closed volume, since in this case the efficiency of gas fire extinguishing is the highest. However, it should be obvious to a person of ordinary skill in the art, for whom this utility model is designed, that the volume to be protected can be any volume in which a sufficient number of the claimed gas devices 100 for extinguishing a fire are placed, the total power of which allows to displace air mass from the protected volume, thereby depriving the ignition source of access to oxygen.

[0025] The present description of the claimed technical solution demonstrates only private embodiments and does not limit other options for its implementation, since possible other alternative embodiments that do not go beyond the scope of the information set forth in this application should be obvious to a person skilled in the art, having the usual qualifications for which the claimed technical solution is designed.
