Description

[0001] This utility model relates to defensive devices, more specifically to a net-throwing device. The utility model can be used for defense against unmanned aerial vehicles.

[0002] A device for throwing a net is known from the prior art, described in https: / / www.ozon.ru / product / setkomet-dlya-kvadrokopterov-fpv-fpv-2308640995 / , and containing a plastic housing in which a pyropatron is located, communicating with a chamber made in the housing, which is then communicated with four extended tubes (barrels).

[0003] The use of plastic parts in the known device, in particular the case, allows to reduce the weight of the device.

[0004] However, in the known device, the pyropatron directly impacts the chamber wall, which can lead to its destruction.

[0005] Thus, the objective of the utility model is to eliminate the shortcomings of the prior art, and the technical result of the utility model is to increase the reliability of the device for throwing a net.

[0006] The said technical result is achieved by a device for throwing a net, which contains

[0007] a plastic case, in the back of which there is a pyropatron, communicating with a chamber made in the case, which then communicates with four through holes made in the case and extending from the said chamber to the front side of the case,

[0008] wherein the axes of the said four extended holes are not parallel to each other and diverge in the direction of the front side of the body, in addition, the said holes are combined into one common hole before communication with the camera,

[0009] also in the housing there is a cavity made open on the front side of the housing, wherein said cavity is made with the possibility of placing a net in it, at the same time, each of the four mentioned extended openings is made with the possibility of placing in it and ejecting from it a load, which is connected by a flexible connection to the net and is equipped with a stop that prevents it from falling into the chamber,

[0010] In addition, a plastic cover is mounted on latches in the front part of the housing, which is designed to prevent the said loads and the said network from spontaneously falling out of the housing.

[0011] It should be noted that such a design allows for increasing the reliability of the device for throwing the net, since the unification of the mentioned four extended holes into one common hole before communication with the chamber, together with the non-parallelism of their axes and the convergence of these axes in the direction of the rear side of the housing, allows for the formation of a central part that cuts the flow of gases from the pyropatron, while the housing remains plastic, accordingly, the weight of the device does not increase or increases only slightly.

[0012] In particular embodiments, the device for throwing a net has the following design.

[0013] The central part, formed by combining the above four extended holes into one common hole, is made sharp.

[0014] The central part formed by combining the above four extended holes into one common hole is made rounded.

[0015] The four extended holes are arranged in such a way that, in a cross-section of the axis of the device, the centers of the said four extended holes are at the corners of the quadrangle.

[0016] The mentioned quadrilateral is a rectangle.

[0017] At its rear, the body is additionally equipped with a means of connecting to the launcher.

[0018] The means of connecting to the launcher is a female part of the bayonet connection.

[0019] The pyropatron is electrically initiated and is installed in the rear part of the body through a threaded adapter sleeve.

[0020] The cavity is offset in the radial direction from the axis of the pyropatron in such a way that in the said direction the distance from the said axis to the cavity exceeds the size of the chamber in the same direction.

[0021] The utility model is explained by the following graphic materials.

[0022] Fig. 1a and 1b. Device for throwing a net, longitudinal section, schematic.

[0023] It should be noted that Figure 1a shows a section illustrating the design in terms of the “upper” or “lower” extended openings (4), and Figure 1b shows a section illustrating the design in terms of the “right” or “left” extended openings (4).

[0024] As illustrated in the figures, the device for throwing a net contains a plastic housing (1), in the rear part of which a pyropatron (2) is located, communicating with a chamber (3) made in the housing (1), which is further communicated with four through holes (4) made in the housing (1) and extending from the said chamber (3) to the front side of the housing.

[0025] The body (1) can be made of various plastics, such as ABS, PLA, PETG and others, by injection molding or 3D printing method such as FDM printing.

[0026] In addition, the axes of the said four extended holes (4) are not parallel to each other and diverge in the direction of the front side of the body, in addition, the said holes are combined into one common hole (5) before communication with the chamber (3).

[0027] It should be noted that when combining the said four extended openings (4) into one common opening (5) before communication with the chamber (3), together with the convergence of the axes of the said four extended openings in the direction of the rear side of the housing, a central part (6) is formed, which cuts the flow of gases from the pyropatron, thus, as such, there is no end of the chamber (3) that perceives the impact from the pyropatron (2), and in place of the end, the said central part (6) is formed, which performs the function of a flow divider (flow guide).

[0028] Practical tests have shown that the said central part (6), formed by combining the said four extended holes (4) into one common hole (5), can be made either sharp or rounded.

[0029] In the housing (1) there is a cavity (7) open on the front side of the housing, in which a network (8) is located, and in each of the said four extended openings (4) with the possibility of ejection there is a load (9), each of which is connected by a flexible connection (10) to the said network (8), and each load (9) is provided with a stop (11), preventing it from falling into the chamber (3).

[0030] The net (8) can be round or rectangular, in particular square with an area of ​​4…9 m 2 , for example, a square 2.5 × 2.5 m.

[0031] The power of the pyropatron, as well as the mass of the loads, are jointly selected to ensure an operating range of 25-30 m, at a speed of about 30 m / s, for example, a common pyropatron with a landing diameter of 15 mm (used in the OSA series of pistols) with four loads of 25 ... 30 g each can be used.

[0032] A plastic cover (12) is mounted on latches (not shown) in the front part of the housing (1), which prevents the said weights (9) and the said net (8) from spontaneously falling out of the housing (1).

[0033] The lid (12), like the body (1), can be made of various plastics using injection molding or 3D printing. The latches can be grooves or recesses with teeth fitting into them.

[0034] Four extended openings (4) are arranged in such a way that in a cross-section of the axis of the device, the centers of said four extended openings are at the corners of a quadrangle, preferably, said quadrangle is a rectangle.

[0035] It is assumed that, in a cross-section of the device's axis, the centers of the four elongated holes are located at the corners of a rectangle (specifically, a square). The closer the cross-section is to the camera, the smaller the rectangle, and the closer the cross-section is to the front of the housing, the larger the rectangle. However, since 3D printing is currently the preferred method for manufacturing the housing (1), some deformation (sag) occurs during printing, and therefore only a rectangular shape is maintained.

[0036] At its rear, the housing (1) is additionally provided with a means of connection (13) to a launcher (not shown), wherein the means of connection (13) to the launcher is a female part of a bayonet connection. It should be noted that the bayonet connection is simple and reliable, and also ensures rapid reloading, clearly positioning the net-throwing device relative to the launcher.

[0037] The pyropatron (2) is electrically initiated and is installed in the rear part of the body through a transition threaded sleeve (14) made of a metal alloy, for example, an aluminum alloy.

[0038] The cavity (7) is offset radially from the axis of the pyrotechnic cartridge (2) such that in said direction, the distance from said axis to the cavity (7) exceeds the size of the chamber (3) in the same direction. Thus, in the direction opposite to said offset, improved visibility is ensured, and, accordingly, aiming (aiming) is facilitated.

[0039] The net throwing device is used as follows.

[0040] The net throwing device is connected to the launcher using the aforementioned connecting means. The launcher can be either stationary or portable, for example, in the form of a pistol. However, a simpler use of the net throwing device is also possible, with its body secured to the base, for example, with a half-clamp and screws.

[0041] Next, to activate the trigger, the operator applies electrical voltage (current) to the squib. This is accomplished through a power source with the required parameters for triggering the squib (e.g., a battery with a converter), a button (which, depending on whether it's stationary or portable, is located on the launcher body, for example, in the form of a pistol trigger, or located separately on a wired or wireless remote control), and a contact group whose contacts interact with the contacts of the squib.

[0042] When the pyropatron is triggered, the expanding gases push the weights out of the holes, accordingly, the weights snap off the cover, and then the flying weights carry the net with them.

[0043] It should be noted that the central part formed by combining the four mentioned extended holes into one common hole dissects (distributes) the flow of gases from the pyropatron and prevents the destruction of the end of the chamber.
