Abstract
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 (CN 119063570 A, 03.12.2024) and provides that the front part of the housing is closed with a plastic cover, which is detached from the housing upon contact with loads flying out of the guide holes (trunks).
[0003] The use of plastic parts in the known device, in particular the cover, allows to reduce the weight of the device.
[0004] However, in the known device there is a risk of penetration of the cover by at least one of the mentioned loads, which leads to disturbances in the flight trajectory of the network, accordingly, reduces the probability of hitting the target.
[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] 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,
[0009] in addition, in the front part of the housing, a plastic cover is mounted with latches, which is designed to prevent the spontaneous falling of the said loads and the said network from the housing, and which contains four protrusions facing the housing, wherein the protrusions are located opposite the ends of the said four extended openings.
[0010] It should be noted that this design allows for increasing the reliability of the net throwing device by preventing the load from penetrating the cover, while the cover and body remain plastic, and accordingly, the weight of the device increases only slightly.
[0011] In particular embodiments, the device for throwing a net provides for the following design.
[0012] The axes of the four long holes mentioned are not parallel to each other and diverge towards the front side of the body.
[0013] At its rear, the body is additionally equipped with a means of connection to the launcher.
[0014] The means of connecting to the launcher is a female part of the bayonet connection.
[0015] The pyropatron is electrically initiated and is installed in the rear part of the body through a threaded adapter sleeve.
[0016] 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.
[0017] The utility model is explained by the following graphic materials.
[0018] Fig. 1a, b - Device for throwing a net, longitudinal section, schematic.
[0019] Fig. 2 - Net throwing device, front view, cover removed, schematic.
[0020] Fig. 3 - Cover of the net throwing device, view from the side facing the body, schematic.
[0021] 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.
[0022] 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.
[0023] In the housing (1) there is a cavity (5) open on the front side of the housing, in which a net (6) is located, and in each of the said four extended openings (4) with the possibility of ejection there is a load (7), each of which is connected by a flexible connection (8) to the said net (6), and each load (7) is provided with a stop (9), preventing it from falling into the chamber (3).
[0024] The net (6) 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.
[0025] The power of the pyropatron, as well as the mass of the loads, are jointly selected to ensure a 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.
[0026] In the front part of the housing (1), a plastic cover (11) is mounted on latches (10), which prevents the spontaneous falling out of the said weights (7) and the said net (6) from the housing (1), and which contains four protrusions (12) facing the housing, wherein the protrusions are located opposite the ends of the said four extended openings (4).
[0027] The lid (11), like the body (1), can be made of various plastics using injection molding or 3D printing. The latches (10) can be grooves or recesses with teeth fitting into them.
[0028] The axes of the said four extended holes (4) are not parallel to each other and diverge towards the front side of the body, respectively, ensuring the full opening of the net at a given distance.
[0029] 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.
[0030] The pyropatron (2) is electrically initiated and is installed in the rear part of the body through a threaded adapter sleeve (14) made of a metal alloy, for example, an aluminum alloy.
[0031] The cavity (5) is offset radially from the axis of the pyrotechnic cartridge (2) such that the distance from the axis to the cavity (5) in the said direction exceeds the size of the chamber (3) in the same direction. Thus, in the direction opposite to the said offset, improved visibility is ensured, and, accordingly, aiming (aiming) is facilitated.
[0032] The net throwing device is used as follows.
[0033] The net throwing device is connected to the launcher using the aforementioned connecting device. 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.
[0034] 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.
[0035] When the pyropatron is triggered, the expanding gases push the weights out of the holes, accordingly, the weights act on the protrusions and snap the cover open, and then the flying weights carry the net with them.
[0036] It should be noted that the interaction of the load with the lid occurs in the place where a protrusion is formed on the lid, thus the probability of the load breaking through the lid is sharply reduced.
