Technical Field
[0001] This utility model relates to the field of artillery barrel maintenance technology, and in particular to a pneumatic barrel cleaning machine for artillery barrels. Background Technology
[0002] After firing, due to the high temperature and pressure environment of the gun barrel, residues from the combustion of gunpowder adhere to the inner wall of the barrel, forming carbon deposits. If these residues are not cleaned promptly, they will affect the normal movement of the projectile within the barrel, causing wear and tear and reducing the gun's firing accuracy. Therefore, cleaning and maintaining the gun barrel is extremely important. However, the internal space of small-caliber artillery barrels is confined and the inner surface is complex, making cleaning these complex surfaces within the narrow, elongated tube quite difficult. Currently, in the armed forces of my country and other countries, the cleaning and maintenance of artillery barrels is mainly done manually. Recently, some semi-automatic and automatic cleaning devices have emerged.
[0003] In the prior art, for example, Chinese Patent Publication No. CN216977652U discloses an electro-pneumatic barrel cleaning machine, including a support cylinder, a connecting cylinder, a gearbox, a second connecting cylinder, and a guide cylinder arranged in sequence. The connecting cylinder is located at the front end of the support cylinder, and the support cylinder and the connecting cylinder are connected by a tapered set screw. A motor is installed inside the connecting cylinder, and the motor output shaft is connected to a helical gear. The side of the helical gear away from the motor is connected to a drive gear via a gear shaft. The gear shaft is connected to the helical gear via a key. A gear is meshed below the drive gear. This invention relates to the field of cleaning and maintenance technology for artillery barrels. It has a simple structure and can effectively and quickly clean artillery barrels. It automatically wipes, saving time and effort, and causes no damage during barrel cleaning. The machine is lightweight and portable, suitable for operation in complex environments such as high altitudes and field conditions. The brush is replaceable and can be customized, applicable to the cleaning and maintenance of various artillery barrels, including field guns, armored guns, aircraft cannons, and naval guns. It can be operated by a single soldier, improving the efficiency and quality of artillery barrel cleaning.
[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: although it can be replaced with a customizable brush, making it suitable for cleaning and maintaining the barrels of various artillery pieces, such as field guns, armored guns, aircraft cannons, and naval guns, and can be operated by a single soldier, thus improving the efficiency and quality of gun barrel cleaning, it requires replacing the brush with one of the appropriate size when cleaning and maintaining gun barrels of different calibers. This process wastes time and reduces the efficiency of cleaning the gun barrels. Utility Model Content

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a pneumatic barrel cleaning machine for artillery, comprising: a gas supply pipe, and further comprising:
[0007] A sleeve is fixedly connected to one side of the gas transmission pipe. A hollow tube is fixedly connected to one side of the sleeve. A movable rod is slidably connected inside the hollow tube. A bracket is rotatably connected to the outer surface of the hollow tube. Multiple square grooves are arranged in a circumferential array on the outer surface of the bracket. Two round rods are symmetrically fixedly connected to opposite sides of the inner wall of the square grooves. A movable strip is rotatably connected to the outer surface of the round rod. A round rod is fixedly connected to the end of the movable strip. Multiple arc-shaped brush plates are arranged in a circumferential array on the outer surface of the bracket. Multiple fixing blocks are symmetrically fixedly connected to each other in pairs on the inner wall of each arc-shaped brush plate. The outer surface of the round rod is rotatably connected to opposite sides of the two fixing blocks. Multiple connecting strips are slidably connected in a circumferential array on one side of the bracket. Each connecting strip is fixedly connected to a movable rod. Multiple fixing strips are symmetrically fixedly connected to each other in pairs on one side of each connecting strip. A round rod is rotatably connected to opposite sides of the two fixing strips. A straight groove is opened on the side of the movable strip away from the round rod. The outer surface of the round rod is slidably connected to the inside of the straight groove.
[0008] Preferably, two L-shaped tubes are symmetrically fixedly connected to one side of the gas transmission pipe, and one end of the two L-shaped tubes is symmetrically fixedly connected to the outer surface of the hollow tube. A solenoid valve is fixedly connected to the L-shaped tube near the inner wall of the gas transmission pipe.
[0009] Preferably, one end of each of the two L-shaped tubes is connected to the inner cavity of the gas transmission pipe, and the other end of each of the two L-shaped tubes is connected to the interior of the hollow tube.
[0010] Preferably, a rubber ring one is fixedly connected to the inner wall of the hollow tube near the sleeve, and a rubber ring two is fixedly connected to one side of the movable rod.
[0011] Preferably, a rotating rod is rotatably connected to one side of the sleeve, the rotating rod is slidably connected to the movable rod, a motor is fixedly connected inside the sleeve, the output end of the motor is fixedly connected to one end of the rotating rod, a first rubber ring is rotatably and sealingly connected to the rotating rod, and a second rubber ring is slidably and sealingly connected to the rotating rod.
[0012] Preferably, a slider is fixedly connected to the other end of the rotating rod, and a groove is provided inside the movable rod, with the outer surface of the slider slidably connected to the inside of the groove.
[0013] Preferably, a spring is provided inside the slide groove, with one end of the spring fixedly connected to one side of the slider and the other end of the spring fixedly connected to one side of the inner wall of the slide groove.
[0014] Preferably, the outer surface of the gas delivery pipe has a plurality of air holes arranged in a circumferential array, and the plurality of air holes are connected to the inner cavity of the gas delivery pipe.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] 1. This utility model uses a controller to open a solenoid valve, allowing gas delivered to the inner cavity of the gas supply pipe to be transported through an L-shaped tube into a hollow tube. With the sealing cooperation of rubber ring one and rubber ring two, the air pressure inside the hollow tube increases, causing the movable rod to slide outwards along the inside of the hollow tube and the slider to slide to one side along the inside of the groove. Simultaneously, the spring is stretched, driving the connecting strip, fixing strip, and round rod three to move to one side. The round rod three slides inside the straight groove and applies a force to the movable strip, causing it to rotate at an appropriate angle around the outer surface of the round rod one. With the cooperation of the round rod two and the fixing block, multiple arc-shaped brush plates move synchronously outwards in parallel, matching the diameter of the artillery barrel. This allows the pneumatic barrel cleaning machine to be adapted to artillery barrels of different diameters without the need for frequent replacement of the arc-shaped brush plates, thereby improving the cleaning efficiency of the artillery barrel.
[0017] 2. This utility model uses a controller to start the motor, causing its output shaft to drive the rotating rod to rotate. Then, with the slider only able to slide inside the groove, it can synchronously drive the movable rod to rotate. The movable rod then drives the connecting strip, bracket, movable strip, and arc-shaped brush plate to rotate. The rotation of the arc-shaped brush plate cleans the inner cavity of the artillery barrel. At the same time, with the cooperation of an external air pump, the gas in the air supply pipe is ejected through the air hole, spraying high-pressure gas into the inner cavity of the artillery barrel. This, combined with the rotation of the arc-shaped brush plate, cleans the inner cavity of the artillery barrel, thus improving the cleaning effect of the inner cavity of the artillery barrel.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0027] Examples, such as Figure 1-5As shown, this utility model provides a pneumatic barrel cleaning machine for artillery, including: a gas supply pipe 1, and a sleeve 2, which is fixedly connected to one side of the gas supply pipe 1. A hollow tube 201 is fixedly connected to one side of the sleeve 2. A movable rod 203 is slidably connected inside the hollow tube 201. A bracket 302 is rotatably connected to the outer surface of the hollow tube 201. The outer surface of the bracket 302 has multiple square grooves 303 arranged in a circular array. Two round rods 304 are symmetrically fixedly connected to opposite sides of the inner wall of the square grooves 303. A movable bar 305 is rotatably connected to the outer surface of the round rod 304. A round rod 306 is fixedly connected to the end of the movable bar 305. The outer surface of the bracket 302 is arranged in a circular array. The column is provided with multiple arc-shaped brush plates 3. Multiple fixing blocks 301 are symmetrically fixed to each other on the inner wall of the arc-shaped brush plates 3. The outer surface of the second round rod 306 is rotatably connected to the opposite side of the two fixing blocks 301. Multiple connecting strips 307 are slidably connected in a circular array on one side of the bracket 302. The multiple connecting strips 307 are all fixedly connected to the movable rod 203. Multiple fixing strips 308 are symmetrically fixed to each other on one side of the connecting strips 307. The opposite side of the two fixing strips 308 is rotatably connected to the third round rod 310. A straight groove 309 is opened on the side of the movable strip 305 away from the second round rod 306. The outer surface of the third round rod 310 is slidably connected to the inside of the straight groove 309.
[0028] Furthermore, such as Figure 1-5 As shown, two L-shaped tubes 202 are symmetrically fixedly connected to one side of the gas transmission pipe 1. One end of each L-shaped tube 202 is symmetrically fixedly connected to the outer surface of the hollow tube 201. A solenoid valve is fixedly connected to the L-shaped tube 202 near the inner wall of the gas transmission pipe 1. The solenoid valve is opened or closed by a controller, which can control the gas inside the gas transmission pipe 1 to enter the hollow tube 201 through the L-shaped tube 202.
[0029] Furthermore, such as Figure 1-5 As shown, one end of each of the two L-shaped tubes 202 is connected to the inner cavity of the gas supply pipe 1, and the other end of each of the two L-shaped tubes 202 is connected to the inside of the hollow tube 201. The L-shaped tubes 202 facilitate the delivery of gas from the inner cavity of the gas supply pipe 1 to the hollow tube 201.
[0030] Furthermore, such as Figure 1-5 As shown, a rubber ring 205 is fixedly connected to the inner wall of the hollow tube 201 near the sleeve 2, and a rubber ring 210 is fixedly connected to one side of the movable rod 203. The rubber ring 205 and the rubber ring 210 provide a certain sealing effect.
[0031] Furthermore, such as Figure 1-5As shown, a rotating rod 204 is rotatably connected to one side of the sleeve 2. The rotating rod 204 is slidably connected to the movable rod 203. A motor 206 is fixedly connected inside the sleeve 2. The output end of the motor 206 is fixedly connected to one end of the rotating rod 204. A rubber ring 205 is rotatably and sealed to the rotating rod 204. A rubber ring 210 is slidably and sealed to the rotating rod 204. The motor 206 is started by the controller, so that its output shaft drives the rotating rod 204 to rotate, which in turn drives the movable rod 203 to rotate.
[0032] Furthermore, such as Figure 1-5 As shown, a slider 209 is fixedly connected to the other end of the rotating rod 204. A groove 207 is provided inside the movable rod 203. The outer surface of the slider 209 is slidably connected to the inside of the groove 207. Through the above arrangement, the slider 209 can only slide inside the groove 207 and cannot rotate.
[0033] Furthermore, such as Figure 1-5 As shown, a spring 208 is installed inside the slide groove 207. One end of the spring 208 is fixedly connected to one side of the slider 209, and the other end of the spring 208 is fixedly connected to one side of the inner wall of the slide groove 207. Under the restoring force of the spring 208, when the air pressure inside the hollow tube 201 returns to the normal level, the movable rod 203 can slide towards the inside of the hollow tube 201.
[0034] Furthermore, such as Figure 1-5 As shown, the outer surface of the gas transmission pipe 1 has multiple air holes 101 arranged in a circular array. All air holes 101 are connected to the inner cavity of the gas transmission pipe 1. By connecting the gas transmission end of the gas transmission pipe 1 to a gas pipe, gas is transmitted through an external air pump, and the high-pressure gas in the inner cavity of the gas transmission pipe 1 is ejected through the air holes 101.
[0035] Working principle: In use, the arc-shaped brush plate 3 is first adjusted according to the diameter of the cannon barrel. Gas is supplied via an external air pump by connecting the gas supply end of the gas supply pipe 1 to the gas pipe. Simultaneously, the controller opens the solenoid valve, allowing the gas supplied to the inner cavity of the gas supply pipe 1 to be transported through the L-shaped pipe 202 into the hollow tube 201. With the sealing cooperation of rubber ring 205 and rubber ring 210, the air pressure inside the hollow tube 201 increases, causing the movable rod 203 to slide outwards along the inside of the hollow tube 201, and the slider 209 to slide along the groove. The interior of 207 slides to one side, simultaneously stretching spring 208, which in turn moves connecting bar 307, fixing bar 308, and round rod 310 to one side. This causes round rod 310 to slide inside straight groove 309, applying a force to movable bar 305, causing it to rotate at an appropriate angle around the outer surface of round rod 304. Adjacent movable bars 305 are arranged parallel to each other, and with the cooperation of round rod 306 and fixing block 301, multiple arc-shaped brush plates 3 move synchronously outwards in parallel, causing the arc-shaped brush plates 3 to move along the movable rod. The radius between the central axes of 203 is increased, allowing multiple arc-shaped brush plates 3 to match the caliber of the gun barrel. Then, the solenoid valve is closed by the controller. This allows the pneumatic barrel cleaning machine to adapt to gun barrels of different calibers, eliminating the need for frequent replacement of the arc-shaped brush plates 3 and improving the cleaning efficiency of the gun barrel. This device is inserted into the gun barrel, supported by an external auxiliary support frame for the gas supply pipe 1. The controller then starts the motor 206, causing its output shaft to drive the rotating rod 204 to rotate. The slider 209 can only move along... With the sliding action inside the chute 207, the movable rod 203 can be rotated synchronously. Then, the movable rod 203 drives the connecting bar 307, bracket 302, movable bar 305, and arc-shaped brush plate 3 to rotate. The rotation of the arc-shaped brush plate 3 cleans the inner cavity of the gun barrel. At the same time, with the cooperation of the external air pump, the gas in the inner cavity of the air supply pipe 1 is ejected through the air hole 101 and high-pressure gas is ejected into the inner cavity of the gun barrel. This, together with the rotation of the arc-shaped brush plate 3, cleans the inner cavity of the gun barrel, thus improving the cleaning effect of the inner cavity of the gun barrel.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
