Description

Technical Field

[0001] The invention relates to the technical field of artillery maintenance, in particular to a device for detecting damage to a barrel and chamber of an artillery gun. Background Art

[0002] According to the existing data, as a barreled weapon, the barrel of a cannon is a tube that gives the projectile a certain initial velocity and direction when it is fired. The internal space of the barrel and its inner wall structure are called the barrel. In order to ensure the long-term availability of the barrel, it should be fully inspected and maintained after it is manufactured and used at each stage, especially the barrel as an important carrier for firing. According to the barrel classification, cannons can be divided into rifled cannons and smoothbore cannons. Rifled cannons have different numbers of spiral rifling grooves engraved in the barrel, which can effectively ensure the stability of the projectile and increase the range. Most modern cannons are rifled cannons. When firing, the projectile rotates along the barrel rifling and has a certain rotation speed after leaving the muzzle, which can maintain stable flight.

[0003] The existing authorized patents and existing equipment with the same technology and similar technology equipment of the same type still have the following problems in daily use:

[0004] As the gun barrel is used for a long time, its interior will be continuously impacted by gunpowder explosion and shell firing. Over time, the inner wall of the gun barrel will be damaged to varying degrees, such as cracks and dents. In order to prevent the barrel from exploding, the inner wall of the gun barrel needs to be inspected regularly. Traditional inspection equipment only uses a special endoscope for observation and inspection, but due to the influence of the light intensity inside the gun barrel, some small cracks cannot be effectively observed, which will cause great safety hazards during use;

[0005] The internal rifling of a rifled gun is spiral, and the carbon deposits produced by the firing of gunpowder will adhere to the rifling. If not cleaned in time, the rifling will be worn out during subsequent firing of the gun. In addition, because the shells rotate at high speed inside the barrel, the shells themselves will rub against the barrel at high speed. After long-term rapid firing of shells, there will be metal residues on the inner wall of the barrel after the friction of the shells. At the same time, after long-term use, the protective layer on the inner wall of the barrel will also be damaged, resulting in rust on the inner wall of the barrel. This requires regular cleaning and maintenance. The traditional maintenance methods are basically divided into three types: mechanical scraping, high-pressure water jet washing and chemical erosion, but these three methods have obvious defects;

[0006] When mechanical scraping is used on rifled guns, the inner grooves of the rifling cannot be effectively cleaned due to the influence of the spiral rifling inside the barrel. In order to increase the cleaning effect, the hard scraper needs to be rubbed against the barrel tightly, which will increase the wear of the barrel and damage the protective layer.

[0007] High-pressure water jet flushing will indiscriminately impact the barrel. Long-term and frequent flushing will also cause certain damage to the protective layer. As the protective layer is damaged, water will directly contact the barrel, which will accelerate the rusting speed of the barrel.

[0008] Chemical corrosion requires a large amount of cleaning agents, is costly, and is not environmentally friendly. If not handled carefully, chemical corrosion damage of varying degrees will occur in the barrel. The above methods will cause varying degrees of damage to the barrel. Nowadays, there is an urgent need for a detection and cleaning equipment that has less damage to the barrel and better cleaning effect. Summary of the invention

[0009] The purpose of this application is to solve or at least alleviate the problems existing in the prior art.

[0010] To solve the above shortcomings, the present invention provides the following technical solutions: an equipment gun barrel and chamber damage detection device, comprising a gun barrel body, wherein a detection component and a maintenance component are arranged at the front of the gun barrel body;

[0011] The detection assembly includes a gas cylinder, which is located in front of the inside of the barrel body. The detection assembly uses high-pressure gas as a driving force to enable the detection assembly to move smoothly in the middle of the inside of the barrel body, and performs damage detection on the inner wall of the barrel body by means of optical detection technology;

[0012] The maintenance component includes a transmission frame, which is sleeved on the surface of the gas cylinder. The maintenance component is used to clean the inner wall of the barrel body and cooperates with the detection component. The two rotate forward and rotate and rub the inner wall of the barrel body to remove impurities.

[0013] Furthermore, the detection component also includes an air pipe, which is fixed and connected to the front side of the air cylinder. The arc surface of the air cylinder is evenly provided with air outlet holes, and the air outlet holes connect the inside and outside of the air cylinder. The back side of the air cylinder is fixed and connected to a spring telescopic tube.

[0014] Furthermore, a calibration block is provided at the rear end of the spring telescopic tube, and a transmission block is slidably connected inside the calibration block. The front side of the transmission block is fixedly connected to the rear end of the spring telescopic tube. The transmission block is conical in shape, and the arc surface of the calibration block is evenly slidably connected to a sliding rod. One end of the sliding rod located inside the calibration block contacts the arc surface of the transmission block.

[0015] Furthermore, one end of the sliding rod away from the calibration block is rotatably connected to a strong magnet, the surface of the strong magnet is covered with a rubber sleeve, the strong magnet is set at an inclined direction of thirty degrees, the inclination direction of the strong magnet is consistent, and an optical detection integration is fixedly installed on the back of the calibration block.

[0016] Furthermore, the transmission frame is fixed to the front side of the calibration block, and the maintenance component also includes a fixing rod, which is provided in four numbers. The four fixing rods are evenly fixed to the arc surface of the transmission frame in a ring shape, and four installation frames are provided on the front side of the transmission frame, and the positions of the installation frames correspond to the fixing rods.

[0017] Furthermore, a first card slot is provided on the back of the installation frame, and a second card slot is provided on the front of the fixing rod. The positions of the first card slot and the second card slot correspond to each other, and the first card slot and the second card slot are embedded in each other. Fixing holes are penetrated inside the first card slot and the second card slot, and rivet blocks are embedded inside the fixing holes.

[0018] Furthermore, four expansion rods are evenly arranged in a ring shape on the front side of the installation frame, the four expansion rods are staggeredly distributed between the four installation frames, and the two ends of the installation frame are respectively slidably connected to the expansion rods on both sides thereof.

[0019] Furthermore, friction blocks are placed inside the installation frame, and the friction blocks are fan-shaped. Sponge blocks are fixedly connected to both sides of the friction blocks. Delivery holes are evenly penetrated inside the friction blocks. A discharge groove is opened on the side of the friction block away from the installation frame. The discharge groove is connected to the delivery hole, and the position of the delivery hole corresponds to the position of the air outlet.

[0020] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0021] 1. The high-speed airflow generated by the air pump impacts the spring telescopic tube as the driving force source of the detection component, so that the calibration block drives the optical detection integration to be in the middle of the barrel body and move deep inside, accurately and automatically calibrating the gun core, so that when the optical detection integration is performing detection work, the distance between the optical detection integration and the inner wall of the barrel body at various locations is the same, and the position state will not change during the detection process, so that the infrared rays released by the optical detection integration are evenly contacted with the inner wall of the barrel body and rebounded. By stabilizing the position state of the optical detection integration, the optical detection integration can effectively receive the rebounded infrared rays, so as to better analyze the inner wall of the barrel body;

[0022] 2. When the calibration block drives the optical detection integration to penetrate deep into the barrel body, the optical detection integration is driven to rotate at a constant speed, so that the infrared light beam released by the optical detection integration can fully contact the inner wall of the barrel body and receive the rebound light. Through rotation, multiple light sources on the optical detection integration can perform multiple inspections on the inner wall of the same position on the barrel body, analyze the multiple inspection results of the same position, thereby improving the inspection effect and avoiding the failure of a single inspection to detect some relatively fine cracks. Moreover, through the rotation of the optical detection integration, multiple groups of light beams are rotated and emitted. When targeting some grooves with a lower degree of depression, the rotating light beam can be irradiated at a large angle on the inner wall of the groove, thereby detecting the depression, and avoiding the possibility that the user may not be able to clearly observe the grooves with a lower degree of depression due to the traditional endoscope;

[0023] 3. By setting the maintenance component, the user will cooperate with the maintenance component and the detection component, so that the friction block and the sponge block move and rotate with the calibration block, so as to clean the impurities on the inner wall of the barrel body. The impurities with different characteristics are cleaned in a targeted manner through the friction blocks and sponge blocks with different hardness, and the stubborn impurities are impacted by the high-speed airflow to loosen them, and cooperate with each other to achieve a good cleaning effect. The soft and highly expandable sponge block can be filled into the groove line for cleaning, which can thoroughly clean the inside of the rifled gun with spiral rifling to avoid the inability to effectively clean the rifling groove, and the stripped impurities are discharged in real time through the discharge groove in combination with the high-speed airflow to avoid the impurities following the friction block and sponge block and rubbing against the inner wall of the barrel body, causing secondary damage;

[0024] 4. The user can switch the shape of the mounting frame, expansion rod, and friction block so that the outer surface of the barrel can be cleaned and coated with protective coating. This device can be used as a carrier for normal cleaning functions to complete cleaning tasks easily and efficiently, and can also change its posture when necessary. By adjusting the operation of the components, it can better complete the maintenance operations on the inner and outer surfaces of the barrel. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The present invention will be further described below in conjunction with the embodiments.

[0041] A gun barrel and chamber damage detection device according to this embodiment is as follows: Figure 1-Figure 10 As shown, it includes a barrel body 101, and a detection component 200 and a maintenance component 300 are arranged in the front of the barrel body 101;

[0042] The detection assembly 200 includes a gas cylinder 201, which is located in front of the barrel body 101. The detection assembly 200 uses high-pressure gas as a driving force to enable the detection assembly 200 to move smoothly in the middle of the barrel body 101, and performs damage detection on the inner wall of the barrel body 101 by means of optical detection technology;

[0043] As a preferred implementation in this embodiment, Figure 1-Figure 10 As shown, the detection component 200 also includes an air pipe 202, which is fixed and connected to the front of the air cylinder 201. The arc surface of the air cylinder 201 is evenly provided with air outlet holes 203, and the air outlet holes 203 connect the inside of the air cylinder 201 with the outside. The back of the air cylinder 201 is fixed and connected to a spring telescopic tube 204. It should be noted that the spring telescopic tube 204 can be deformed and stretched under force. After the external force disappears, the resilience of the spring telescopic tube 204 after its own deformation can drive the spring telescopic tube 204 to shrink to the initial state;

[0044] As a preferred implementation in this embodiment, Figure 1-Figure 10 As shown, a calibration block 205 is provided at the rear end of the spring telescopic tube 204, and a transmission block 206 is slidably connected inside the calibration block 205. The front of the transmission block 206 is fixedly connected to the rear end of the spring telescopic tube 204. The transmission block 206 is conical, and the arc surface of the calibration block 205 is evenly slidably connected with a slide rod 207. One end of the slide rod 207 located inside the calibration block 205 contacts the arc surface of the transmission block 206. It should be noted that one end of the slide rod 207 located inside the calibration block 205 is obliquely cut, and the position where the slide rod 207 contacts the arc surface of the transmission block 206 is the inclined surface after the angle is cut.

[0045] One end of the slide bar 207 away from the calibration block 205 is rotatably connected to a strong magnet 208, the surface of the strong magnet 208 is covered with a rubber sleeve 209, the strong magnet 208 is set at an inclined direction of thirty degrees, the inclination direction of the strong magnet 208 is consistent, and an optical detection integration 210 is fixedly installed on the back of the calibration block 205.

[0046] Comparing existing authorized patents, equipment with the same technology, and similar technology equipment of the same type, the following results are achieved:

[0047] The calibration block 205 drives the optical detection integration 210 to be located in the middle of the barrel body 101 and move to the depth, accurately and automatically calibrating the gun core, so that when the optical detection integration 210 is performing detection work, the distance between the optical detection integration 210 and the inner wall of each part of the barrel body 101 is the same, and the position state will not change during the detection process, so that the infrared rays released by the optical detection integration 210 are uniformly in contact with the inner wall of the barrel body 101 and rebound;

[0048] The multiple light sources on the optical detection integrated circuit 210 perform multiple inspections on the inner wall of the same position on the barrel body 101, and analyze the multiple inspection results of the same position, so as to improve the inspection effect and avoid the situation where a single inspection fails to detect some finer cracks. The optical detection integrated circuit 210 rotates and multiple groups of light beams are emitted. When targeting some grooves with a lower degree of depression, the rotating light beams can be irradiated at a large angle on the inner wall of the groove, so as to detect the depression.

[0049] In other aspects, this embodiment also provides a gun barrel and chamber damage detection device, such as Figure 1-Figure 10 As shown, the maintenance component 300 includes a transmission frame 301, which is sleeved on the surface of the gas cylinder 201. The maintenance component 300 is used to clean the inner wall of the barrel body 101, and cooperates with the detection component 200. The two rotate forward and rotate and rub the inner wall of the barrel body 101 to remove impurities.

[0050] As a preferred implementation in this embodiment, Figure 1-Figure 10 As shown, the transmission frame 301 is fixed to the front of the calibration block 205, and the maintenance component 300 also includes a fixing rod 302, and the fixing rod 302 is set to four. The four fixing rods 302 are evenly fixed to the arc surface of the transmission frame 301 in a ring shape, and four installation frames 303 are set on the front of the transmission frame 301. The positions of the installation frames 303 correspond to the fixing rods 302;

[0051] A first card slot 304 is provided on the back of the mounting frame 303, and a second card slot 305 is provided on the front of the fixing rod 302. The positions of the first card slot 304 and the second card slot 305 correspond to each other, and the first card slot 304 and the second card slot 305 are embedded and engaged with each other. A fixing hole 306 is provided inside the first card slot 304 and the second card slot 305, and a rivet block 307 is embedded inside the fixing hole 306. It should be noted that the rivet block 307 is a regular hexagonal column, and the shape of the fixing hole 306 is consistent with that of the rivet block 307, and the inner wall of the fixing hole 306 is tightly attached to the surface of the rivet block 307;

[0052] The front of the installation frame 303 is evenly provided with four expansion rods 308 in a ring shape. The four expansion rods 308 are staggeredly distributed with the four installation frames 303. The two ends of the installation frame 303 are respectively slidably connected with the expansion rods 308 on both sides thereof. It should be noted that the installation frame 303 and the expansion rods 308 are both made of pure iron.

[0053] As a preferred implementation in this embodiment, Figure 1-Figure 10As shown, friction blocks 309 are placed inside the installation frame 303, and the friction blocks 309 are fan-shaped. Sponge blocks 310 are fixedly connected on both sides of the friction blocks 309. Delivery holes 312 are evenly penetrated inside the friction blocks 309. A discharge groove 311 is opened on the side of the friction blocks 309 away from the installation frame 303. The discharge groove 311 is connected with the delivery hole 312. The position of the delivery hole 312 corresponds to the position of the air outlet 203. It should be noted that the friction blocks 309 and the sponge blocks 310 form a fan shape, and the friction blocks 309 are squeezed and deformed with the inner wall of the installation frame 303. The resilience of the friction blocks 309 after deformation makes the friction blocks 309 contact and fix with the inner wall of the installation frame 303. The friction blocks 309 are made of hard rubber material, and the delivery holes 312 are in contact and connected with the corresponding air outlets 203, and the front inner wall of the discharge groove 311 is in an open state.

[0054] Comparing existing authorized patents, equipment with the same technology, and similar technology equipment of the same type, the following results are achieved:

[0055] The friction blocks 309 and sponge blocks 310 with different hardness are used to clean impurities with different characteristics, and the high-speed airflow impacts the stubborn impurities to loosen them, and cooperates with each other to achieve a good cleaning effect. The soft and highly expandable sponge block 310 can be filled into the groove line for cleaning, and the inside of the spiral rifling rifled gun can be thoroughly cleaned;

[0056] The device can be used as a carrier of normal cleaning functions to complete cleaning tasks easily and efficiently, and can also change postures when needed to better complete maintenance operations on the inner and outer surfaces of the gun barrel by adjusting the operation of components.

[0057] The above complete working principle and working process are as follows:

[0058] Please refer to Figure 1-Figure 10 , the following is the specific working process of the detection component 200 detecting the inside of the barrel body 101;

[0059] When the user needs to inspect the inside of the barrel body 101, the user pushes the inspection component 200 and the maintenance component 300 from the front end of the barrel body 101 into the barrel body 101, and then connects the air pipe 202 to the external high-pressure air pump and starts the air pump. The air pump delivers a high-speed airflow to the inside of the air pipe 202. The high-speed airflow enters the inside of the air cylinder 201 and enters the inside of the spring telescopic tube 204. The high-speed airflow impacts the inner wall on the back side of the spring telescopic tube 204. The impact force pushes the spring telescopic tube 204 to move backward and extend. Because the spring telescopic tube 204 is fixedly connected to the transmission block 206, the spring telescopic tube 204 pushes the transmission block 206 to move toward the inside of the calibration block 205. It is known that the slide bar 207 is located inside the calibration block 205. One end of the slider 207 contacts the arc surface of the transmission block 206, and one end of the slider 207 located inside the calibration block 205 is beveled. The position where the slider 207 contacts the arc surface of the transmission block 206 is the bevel after beveling. When the transmission block 206 moves toward the inside of the calibration block 205, the slider 207 and the strong magnet 208 are pushed to move. Affected by the arc surface of the transmission block 206 and the bevel after the bevel of the slider 207, the slider 207 moves away from the calibration block 205. The slider 207 drives the strong magnet 208 and the rubber sleeve 209 to move in the same direction. Because multiple sliders 207 are pushed by the transmission block 206 to move the same distance, the strong magnet 208 and the rubber sleeve 209 move the same distance, thereby 207, strong magnet 208 and rubber sleeve 209 support calibration block 205, so that calibration block 205 is located in the middle of the barrel body 101. At the same time, optical detection integration 210 is located in the middle of the back of calibration block 205. Optical detection integration 210 also follows calibration block 205 and is located in the middle of the barrel body 101. At this time, due to the resistance of the inner wall of the barrel body 101, slide bar 207, strong magnet 208 and rubber sleeve 209 cannot continue to move. At this time, spring telescopic tube 204 is pushed by high-speed airflow and still has a tendency to stretch. The thrust is transmitted to calibration block 205 through transmission block 206 and slide bar 207, thereby pushing calibration block 205 to move deep into the barrel body 101. It is known that strong magnet 208 is inclined. The strong magnet 208 is set at an oblique thirty degrees, and the inclination direction of the strong magnet 208 is consistent. When the calibration block 205 moves, the strong magnet 208 and the rubber sleeve 209 are also moved. However, the rotation direction of the strong magnet 208 is inconsistent with the movement direction of the calibration block 205. Driven by the calibration block 205, the strong magnet 208 rotates in the direction of its own inclination angle, so that the calibration block 205 can move smoothly. However, affected by the inclination factor of the strong magnet 208, during the backward movement of the calibration block 205, it is driven by the strong magnet 208 to follow the rotation of the strong magnet 208 and drive the optical detection integration 210 to rotate. The optical detection integration 210 follows the calibration block 205 and continuously enters deep into the barrel body 101. The optical detection integration 210 emits multiple groups of infrared light beams.After the infrared beam contacts the inner wall of the barrel body 101, it bounces back and is received by the receiving unit on the optical detection integration 210. Then, the optical detection integration 210 transmits the received data to the external terminal, and the terminal analyzes the damage of the inner wall of the barrel body 101.

[0060] The effect obtained according to the above movement process is: the high-speed airflow generated by the air pump impacts the spring telescopic tube 204 as the driving force source of the detection component 200, so that the calibration block 205 drives the optical detection integration 210 to be in the middle of the barrel body 101 and move to the depth, accurately and automatically calibrating the gun core, so that when the optical detection integration 210 is performing detection work, the distance between the optical detection integration 210 and the inner wall of the barrel body 101 at various locations is the same, and the position state will not change during the detection process, so that the infrared rays released by the optical detection integration 210 are uniformly in contact with and rebound from the inner wall of the barrel body 101, and by stabilizing the position state of the optical detection integration 210, the optical detection integration 210 can effectively receive the infrared rays that bounce back, so as to better analyze the inner wall conditions of the barrel body 101;

[0061] When the block to be calibrated 205 drives the optical detection integration 210 to penetrate deep into the barrel body 101, the optical detection integration 210 is driven to rotate at a constant speed, so that the infrared light beam released by the optical detection integration 210 can fully contact the inner wall of the barrel body 101 and receive the rebound light. Through rotation, multiple light sources on the optical detection integration 210 can perform multiple inspections on the inner wall of the same position on the barrel body 101, and analyze the multiple inspection results of the same position, thereby improving the inspection effect and avoiding the failure of a single inspection to detect some relatively fine cracks. Moreover, through the rotation of the optical detection integration 210, multiple groups of light beams are rotated and emitted. When targeting a groove with a lower degree of depression, the rotating light beam can be irradiated on the inner wall of the groove at a large angle, thereby detecting the depression, while a traditional endoscope may cause the user to be unable to clearly observe the groove with a lower degree of depression.

[0062] Please refer to Figure 1-Figure 10 , the following is the specific working process of the detection component 200 detecting the inside of the barrel body 101;

[0063] The user inserts the friction block 309 and the sponge block 310 into the interior of the installation frame 303. It is known that the friction block 309 and the sponge block 310 form a fan shape. The friction block 309 and the inner wall of the installation frame 303 are squeezed and deformed. The friction block 309 is fixed to the inner wall of the installation frame 303 through the resilience of the deformation. The friction block 309 is made of hard rubber material. The delivery hole 312 is in contact and connected with the corresponding air outlet 203, and then follows the calibration block 205 into the interior of the barrel body 101, and the calibration block 205 rotates to drive the transmission frame 301 to rotate. The transmission frame 301 drives the installation frame 303, the friction block 309 and the sponge block 310 to rotate through the fixing rod 302, the rivet block 307 and the fixing hole 306 The internal part of the barrel body 101 is cleaned by friction through the rotating friction block 309 and the sponge block 310. The friction block 309 made of hard rubber material can scrape and clean the impurities firmly adhering to the inner wall of the barrel body 101, but the hardness of the friction block 309 is lower than that of the barrel body 101, and the friction and scraping of the rubber sleeve 209 will not cause damage to the barrel body 101, while the soft sponge block 310 can wipe and clean some fine-grained gunpowder residues. The user can also immerse the sponge block 310 in the cleaning liquid, and the sponge block 310 is filled with the cleaning liquid. When it contacts and rubs with the inner wall of the barrel body 101, the cleaning liquid continuously seeps out to increase the cleaning effect. According to the movement process of the above-mentioned detection component 200, it can be known that the air pipe 202 is continuously connected to the external air pump. A high-speed airflow is input into the air cylinder 201, and the high-speed airflow is continuously accumulated in the air cylinder 201, and then discharged through the air outlet 203. It is known that the discharge groove 311 is connected to the delivery hole 312, and the position of the delivery hole 312 corresponds to the position of the air outlet 203. The high-speed airflow enters the delivery hole 312 through the air outlet 203 and is discharged. When the friction block 309 rubs against the inside of the barrel body 101, the high-speed airflow ejected through the delivery hole 312 impacts the impurities firmly adhered to the inner wall of the barrel body 101, so that the impurities are loosened. The impurities on the barrel body 101 can be completely cleaned with the friction block 309. After being ejected from the delivery hole 312, the high-speed airflow also enters the discharge groove 311. Because the friction block 309 and the sponge block 31 0 conflicts with the inner wall of the barrel body 101, and the peeled impurities will also fall into the discharge groove 311. It is known that the front inner wall of the discharge groove 311 is in an open state. Driven by the high-speed airflow, the impurities in the discharge groove 311 will be discharged from the front end opening of the discharge groove 311, waiting for the subsequent extraction of the detection component 200 and the maintenance component 300 from the barrel body 101, and the impurities will be pushed out by the friction block 309 and the sponge block 310. When the maintenance of the inner wall of the barrel body 101 is completed, the user extracts the rivet block 307 from the fixing hole 306, and then separates the card slot 1 304 and the card slot 2 305, thereby separating the installation frame 303 from the fixing rod 302. Similarly, the above operation can be repeated in reverse to fix the installation frame 303 on the fixing rod 302.By engaging the first and second card slots 304 and 305 with each other, and by engaging the auxiliary rivet block 307 and the fixing hole 306 with each other, the installation frame 303 is stably fixed on the fixing rod 302. The user takes out the disassembled installation frame 303 from the gas cylinder 201. It is known that the two ends of the installation frame 303 are respectively slidably connected with the expansion rods 308 on both sides thereof. The user pulls the four expansion rods 308 to make the two ends of the installation frame 303 slide on the expansion rods 308, thereby expanding the closed loop formed by the installation frame 303 and the expansion rods 308. Then the user inserts the friction block 309 from the inside of the closed loop formed by the gas pipe 202 and the expansion rods 308 into the inside of the installation frame 303, so that the discharge groove 311 on the friction block 309 faces the middle of the closed loop, and then the closed loop formed by the installation frame 303 and the expansion rods 308 is sleeved on the barrel body. 101, it is known that the mounting frame 303 and the expansion rod 308 are both made of pure iron, and the strong magnet 208 will release a strong magnetic field, and the strong magnet 208 adsorbs the mounting frame 303 and the expansion rod 308, so that the closed loop composed of the mounting frame 303 and the expansion rod 308 drives the friction block 309 and the sponge block 310 to adhere tightly to the outer surface of the barrel body 101, and then the user starts the external air pump again, so that the calibration block 205 moves deep into the barrel body 101, and the suction force of the strong magnet 208 drives the mounting frame 303 and the expansion rod 308 to move in the same direction on the outer surface of the barrel body 101, and the friction block 309 and the sponge block 310 are used to clean the surface of the barrel body 101 again, and the user can inject the protective coating into the sponge block 310, and the sponge block 310 is used to evenly coat the surface of the barrel body 101;,

[0064] The effect that can be obtained according to the above movement process is: by setting the maintenance component 300, the user cooperates the maintenance component 300 with the detection component 200, so that the friction block 309 and the sponge block 310 follow the calibration block 205 to move and rotate, thereby cleaning the impurities on the inner wall of the barrel body 101, and the impurities with different characteristics are targetedly cleaned by the friction blocks 309 and sponge blocks 310 with different hardness, and the stubborn impurities are impacted by the high-speed airflow to loosen them, and cooperate with each other to achieve a good cleaning effect, and the soft and highly expandable sponge block 310 can be filled into the groove line for cleaning, and the inside of the rifled gun with spiral rifling can be thoroughly cleaned to avoid the inability to effectively clean the rifling groove, and the stripped impurities are discharged in real time through the discharge groove 311 in conjunction with the high-speed airflow to avoid the impurities following the friction block 309 and the sponge block 310 and rubbing against the inner wall of the barrel body 101, causing secondary damage;

[0065] The user can switch the shape of the mounting frame 303, the expansion rod 308, and the friction block 309 so that the outer surface of the barrel body 101 can be cleaned and coated with protective coating. This device can be used as a carrier of normal cleaning functions to easily and efficiently complete the cleaning task, and can also change its posture when necessary. By adjusting the operation of the components, it can better complete the maintenance operations on the inner and outer surfaces of the barrel.
