Description

Technical field

The claimed technical solution relates to devices for cleaning the inner surfaces of pipes, and in particular, to devices for cleaning the inner surface of the barrel of a weapon.

State of the art

When a shot is fired from a weapon, the chemicals in the cartridge are burned. This leads to the formation of a large amount of gas that pushes the shot object, in the particular case - a bullet, into the barrel. Expanding gases cause the bullet to accelerate along the barrel. Inside the barrel of most modern guns, very thin spiral grooves are made, called slicing, which make the bullet rotate when passing through the barrel. The rotation of a bullet in flight significantly increases the stability of its flight. This is important to improve accuracy. During the passage of the barrel, the bullet crashes into its grooves with its side surface. In addition to bullet metal particles, expanding gases leave precipitating substances and combustion products on the surface of the barrel. Precipitating substances after many shots accumulate on the walls of the barrel.

To eliminate clogging of the bore with accumulated deposits, these deposits must be removed by cleaning. Traditionally, barrel cleaning is performed by pushing a cleaning metal (wire) brush through the barrel, or by pulling (pulling) through the barrel a woven material soaked in solvent and / or lubricating oil. Typically, these operations are performed sequentially. One of the known technologies for cleaning the bore in this way is to use a rigid composite aluminum ramrod. The components are joined together before use. A fixture can be attached to one end, which can be a metal brush, a special holder for cleaning grooves, adapted to secure a tissue cleaning / grease swab. The solvent can be applied using a tissue swab or a stiff brush for better handling of hard-to-reach spots. A metal brush is more effective for cleaning metal deposits. After cleaning by physical and chemical effects, cleaning is performed with a cleaning swab. A cleaning swab removes residual deposits and solvent residues. The final cleaning step is to lubricate the barrel with a swab soaked in gun grease. After that, a thin layer of oil remains on the barrel to protect it from corrosion.

Using the traditional method has several disadvantages. The method includes the operations of attaching and disconnecting nozzles during the cleaning process. This increases the time spent and the complexity of use. In addition, particles and parts of fabric and rope may remain in the barrel during cleaning. Also, the cleaning swab may get stuck in the barrel if its size is not selected correctly, which leads to difficulties in removing the remnants of the swab from the barrel.

The technical result achieved by the utility model consists in performing several cleaning operations in a single pass of the device along the bore, thereby reducing labor costs and time to complete the operation. Among the operations that can be performed in one pass of the tool can be: (1) removal of solid particles from the barrel before passing a metal or other solid brush; (2) applying a cleaning agent (solvent) to the inside of the barrel; (3) cleaning the barrel with a wire brush; (4) the absorption of the cleaning agent (solvent) and the collection of solid particles that appear after brushing; (5) applying a thin layer of gun grease and distributing it evenly throughout the barrel.

Another technical result is the elimination of the possibility of fragments of cords, stuck tampons, brushes, devices in the barrel due to the adoption of measures to prevent improper operation of the device.

Another technical result is the creation of a device having a low weight, significant ease of transportation in the field, with a minimum content or complete absence of metal parts commonly used in cleaning devices.

Another technical result is to obtain a device that does not require assembly and disassembly, change devices, etc., and which is always ready for use.

DISCLOSURE OF TECHNICAL SOLUTION

The claimed technical result is achieved thanks to a cleaning device in the form of a fabric cylindrical sleeve for cleaning the inner surface suitable for many different pipes, including gun shafts. It can also be other types of pipes, product pipelines in food production, chemical production, pipes of stock systems and many others. The design includes a brush and a fabric sleeve. The brush consists of a housing on which the bristles are fixed. The bristles protrude from the body. The brush body is enclosed inwardly and surrounded on all sides by a cylindrical cloth sleeve. The bristles of the brush extend outward (sticks out) through the wall of the fabric sleeve. This device is used by pulling a fabric sleeve (with a brush inside) through the pipe, while the bristles of the brush, penetrating through the surface of the wall of the fabric sleeve, clean the inner surface of the pipe or barrel of the gun. In this embodiment of the device, the fabric sleeve should be made of woven material of loose weaving.

In the best version of the device, the fabric sleeve should be made of woven material - multi-thread from a bulk thread of free, sparse weaving, allowing to reduce its diameter, if necessary, to be inserted into a pipe of a smaller diameter without damage.

In accordance with another embodiment, a cleaning device in the form of a cylindrical cloth sleeve is designed to clean the inner surface of the barrel of a weapon. This option includes local thickening (increase in diameter) due to the placement inside the cylindrical fabric sleeve elastic, mainly foam insert. Due to the volume of the texture of the thread, due to the loose weaving of the fabric material of the sleeve, under the influence of the elastic insert there is a local increase in the diameter of the fabric sleeve. Due to the elasticity of the insert when pulling the device through the barrel of the weapon, the diameter of the fabric sleeve is adjusted (adjusted) in size to the diameter of the barrel being cleaned, the pressure of the wall of the fabric sleeve on the internal surface being cleaned increases, which leads to improved cleaning. You can place several such inserts in series and get several thickenings along the length of the fabric sleeve. Local thickening can also be formed by inserting a part of the sleeve inside itself, and in this position, fix, for example, by sewing. You can do the insertion of the sleeve into yourself repeatedly - twice, three times.

In accordance with another embodiment, the cleaning device in the form of a fabric sleeve may include a number of devices (sections) for performing several operations of cleaning weapons in one pass.

In this embodiment, the cleaning device includes a brush, which consists of a housing and fixed on it and protruding bristles.

The device also contains one or more cleaning parts (sections) located adjacent to the length of the fabric sleeve with the brush body and used to contact the surface being cleaned and to clean it. These parts are enclosed in a flexible fabric sleeve.

The cleaning portion in this embodiment may include elastic sponge inserts placed inside the fabric sleeve. The cleaning parts can also be made in the form of adjacent adjacent parts of the fabric sleeve inserted into themselves to obtain the required diameter of the device. The fabric sleeve is preferably made of woven material.

The device may include a weight attached to the front end of the fabric sleeve to facilitate the passage of weapons through the barrel. Also, to facilitate the passage of weapons through the barrel, a cord may be attached to the front end of the fabric sleeve, possibly with a plastic coating to give additional rigidity, and a weighting agent is attached to the specified cord. The weighting agent is lowered into the barrel and taken at the exit of the barrel. Then, using a cord, a fabric sleeve with cleaning and lubrication devices installed inside is pulled along the barrel.

The fabric section may also be rigid or semi-rigid, partially rigid, stacked on a flexible coupling of rigid, and / or semi-rigid and flexible elements.

In accordance with another embodiment, the cleaning device in the form of a fabric sleeve may include a number of devices for performing several operations of cleaning weapons in one pass. In accordance with the specified embodiment, the device further includes several elements sequentially placed in a fabric sleeve of woven material, each of which is designed to perform one or more operations - to remove particles, residual liquids - both before and after passing the element with a wire brush.

According to another embodiment, the cleaning device in the form of a fabric sleeve may include one or more inserts in the form of elastic foam material for more strongly pressing the woven fabric of the fabric sleeve to the surface to be cleaned to achieve better cleaning, for applying the cleaning agent to the surface to be cleaned, for applying lubricant to the lubricated surface, to remove fluids from the surface. Elastic foam inserts can be both from absorbent and non-absorbent material.

The device according to the proposed design can be made without metal parts, except for finished components manufactured by other manufacturers that do not have a completely non-metallic embodiment - for example, a bristle of a metal brush, which can be made of bronze, other soft materials so as not to scratch the inner surface of the barrel.

Other advantages of the proposed design can be identified by specialists in this field when using, manufacturing, modification of the structure, other obvious improvements.

DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE DEVICE.

Figure 1 shows the advantages of the proposed solution. The cleaning device includes a cylindrical fabric sleeve 2, a brush 3, a foam insert 4 (optional), a cleaning section 9, a cleaning section 10, a weighting agent (load) 5, a cord 11, a lubricating tampon 6. The cleaning sections 9 and 10 can be made by simple folding or embedding into each other the neighboring parts 12 of the fabric sleeve 2, as shown, for example, in Fig. 5 and Fig. 5a. The brush device 3 is shown in FIG. 2, and includes a brush body 7 and bristles 8. A grease swab 6 is shown in more detail in FIG. 3. In a preferred embodiment of the claimed solution, the lubricating tampon is formed from a part of the fabric sleeve 2, which is nested inside to increase the size, while the loose fluffy remaining part of the fabric sleeve 2 protruding from the backward location of the fabric 2. The lubricating tampon 6 can be formed as a loop or folding of the fabric sleeves 2 (possibly with fixing stitching).

The woven material of the fabric sleeve 2 is made (for weapons of small caliber), preferably from loose twisted threads. For weaving, they use filament of volumetric texture - wavy or zigzag in shape. Many woven threads give the fabric sleeve 2 high strength. When forming a section from a fabric sleeve by inserting one part of the section into another - adjacent, the resulting design exerts increased pressure on the walls of the pipe (barrel of the weapon) to be cleaned and its advancement in the pipe requires increased effort.

The material of the yarns is usually coarse textured nylon (from filaments of bulk texture), but polyester, cotton and other materials can be used. These materials have a bulk texture. This texture provides both increased elasticity, friction and absorption to clean the inner surface of the barrel of the weapon.

A preferred embodiment also involves the use of a cord 11 attached to a fabric sleeve 2. The cord 11 is preferably made of a nylon cord. The main requirement for it is sufficient strength and a length greater than the length of the barrel being cleaned. The other end of the cord is attached to a weighting agent (load) 5, which facilitates the passage of the cord through the bore. To increase rigidity, the cord may be coated or impregnated with plastic.

Brush 3 is selected according to the size (caliber) of the barrel. Its diameter should be approximately 0.2-0.5 mm larger than the diameter of the barrel, and depends on the material of the brush bristles.

The diameter of the elastic foam insert (sponge) 4 also depends on the caliber of the barrel of the weapon and should be 0.5-5 mm (or more) larger than the diameter of the barrel. The elastic foam insert 4 used in the cleaning section 10 is selected 0.1-0.5 mm less than the diameter of the elastic foam insert used in the section 9. The difference is due to the fact that the section 9 is further compressed by pushing the brush 3 located after it.

The cleaning section can also be made by inserting one part of the section of the fabric sleeve 2 into the other.

Another preferred embodiment of the claimed design is presented in figure 4. This option includes a brush 3, a cleaning section 9, a cleaning section 10, a cord 11 with a plastic coating, connecting elements 13.

Another preferred embodiment of the claimed design is presented in FIGS. 6 and 3. This embodiment is intended for processing (cleaning and lubricating) large-caliber barrels, such as, for example, smooth-bore hunting rifles. A large brush is covered (sandwiched between) two or more fabric sleeves 2, as shown in Fig.6. The fabric sleeves are sewn together before and after the body 7 of the brush 3. The bristles 8 of the brush 3 penetrate through the walls of the fabric sleeves. In this embodiment, an insert made of elastic foam material can be used to form (increase the size) of the cleaning section, or one or both of the fabric sleeves can be rolled up into a loop 12, as shown in FIG. 6 and FIG. 3 (and additionally fixed by stitching).

Another variant of the claimed design suggests that to improve consumer properties, the fabric sleeve can be made not only cylindrical, but also conical - expanding or tapering, having a variable cross-section that varies along the length of the sleeve according to any law given in advance. You can use a fabric sleeve, the shape of which is formed by a combination of cylindrical and / or conical, and / or spherical and / or other, including asymmetric surfaces.

The operation of the device is shown in figures 1, 4, 5, 6. The device operates as follows. The weighting agent (load) 5 or the front (leading) end for the stiffness of the cord 11 covered with plastic (for example, vinyl) is inserted into the open hole of the barrel (mainly from the breech) and lowered and / or additionally pushed until the barrel appears from the opposite hole. To increase the cleaning efficiency, it is possible to impregnate the front (leading) end of the cleaning section 9 with a solvent, use a brush 3, and soak a tampon 6 with gun oil. Then, the fabric sleeve 2 is gripped (by the attached cord) and pulled through the barrel so that the front (leading) the end of the cleaning section 9 enters the barrel and collects mechanical particles found in the barrel, such as dirt, ice, sand, etc. In addition, a cleaning fluid (e.g., solvent) that impregnated the insert of the cleaning section 9 is extruded and distributed on the surface of the barrel. As the cloth sleeve moves along the bore, the brush 3, following the cleaning section 9, comes into contact with the barrel surface. The bristles of the brush remove metal particles and combustion products from the surface of the barrel. Upon entering the barrel of the cleaning section 10, its leading edge absorbs the cleaning agent (solvent), collects metal particles and particles of combustion products. Upon entering the trunk of the tail part of the fabric sleeve 2, the now clean surface of the barrel is lubricated with a thin layer of gun oil.

If the barrel is very dirty or has significant metal deposits due to heavy duty and has not been cleaned for a long time, it is possible to use reciprocating movements in the cleaning process. This mode includes performing short movements of the cleaning device forward and backward, with the gradual advancement of the device towards the exit from the barrel.

An embodiment of a device for performing such a cleaning mode is shown in FIG. The device can be equipped with an additional cleaning section, organized (attached) after (in the direction of movement) of the cleaning section 10, the specified additional section can serve as an additional lubricating swab. An additional lubricating section may be attached to the tail of the cleaning section 10, acting as the lubricating part of the device. In this embodiment of the device, the cleaning section 9, the cleaning section 10 and the brush 3 can be disconnected from the cable 11. This allows the device user to use only the cleaning section 9 together with the brush 3 if the device 13 is for detachable connection and detach parts (sections) only the cleaning section 9 without the use of a brush 3 and without the use of the cleaning section 10.

The embodiment of the device shown in FIG. 1 can also be assembled from a different set according to the number and nomenclature of elements without the help of connecting elements 13, but only by placing the necessary elements along the length of the fabric sleeve, and forming elements from parts of the fabric sleeve itself by folding and / or self-attachment (embedding one section of the sleeve inside another adjacent). Thus, it is possible, if necessary, not to use the brush 3, or to make sure that only the cleaning section 9 would be part of the device, and the brush 3 and the cleaning section 10 are not present. Thanks to the elastic foam inserts enclosed in the fabric sleeve 2, it is possible to obtain a processing surface of 1 to 650 square meters. see, which is much more than any swab when cleaning weapons in the traditional way. Also, the elastic foam insert allows to obtain sufficient pressure on the wall, has significant absorption capabilities.

The device is lightweight, made from inexpensive materials, can be reused, washed, cleaned.
