Abstract
Description
Technical Field
[0001] This utility model relates to an automated gun barrel cleaning device, and more particularly to a gun barrel wiping machine. Background Art
[0002] When artillery fires a shell, the breech is subjected to high-speed friction from the shell and the burning of gunpowder. With each firing, a significant amount of residue accumulates on its inner surface. Therefore, the breech requires regular cleaning and maintenance. To reduce the workload of soldiers and improve the efficiency of breech cleaning and maintenance, automated breech wiping equipment has been introduced in existing technology. However, due to the rifling grooves within the breech, existing breech wiping equipment is not very effective at cleaning the grooved areas. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a gun barrel wiping machine that can overcome the shortcomings of the existing technology and improve the wiping effect of the gun barrel.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.
[0005] A gun barrel cleaning machine includes a housing. A cotton cloth cleaning head is installed at the top of the housing, and a power cord connector and a signal cord connector are provided at the rear of the housing. A drive roller is provided on the side wall of the housing. An annular brush mounting area is provided in the middle of the side wall of the housing, and a plurality of brush mechanisms are evenly installed in the brush mounting area. The brush mechanism includes a rotary motor installed inside the housing. The output end of the rotary motor is mounted on a base via a spring. The housing has holes for mounting the base. A flange is provided on the side wall of the base. A sinusoidal guide groove is provided on the side wall of the hole. The flange is slidably mounted in the guide groove. The base moves up and down as the position of the flange in the guide groove changes during rotation. Four shafts that rotate freely along the axis are provided at the top of the base. The included angle between adjacent shafts is 90°. Brush heads are fixed on the shafts.
[0006] Preferably, each brush mechanism is provided with a spray hole next to it, and a liquid storage tank is installed inside the housing. The liquid storage tank is connected to the spray hole through a liquid supply pump and a liquid delivery pipe.
[0007] Preferably, the spray direction of the spray hole is inclined towards one side of the base, and a baffle is provided at the top edge of the base, with the baffle parallel to the side wall of the base.
[0008] Preferably, a camera is provided at the rear of the housing, and a position sensor is provided on the side wall of the housing.
[0009] The beneficial effects of adopting the above technical solution are as follows: This utility model adopts a wiping structure of "wiping head + cleaning brush", and by improving the structure of the brush head, it can effectively clean the inner wall of the gun barrel, especially the rifling area. Attached Figure Description
[0010] Figure 1 This is a structural diagram of a specific embodiment of the present invention.
[0011] Figure 2 This is a cross-sectional view of the brush mechanism in a specific embodiment of this utility model.
[0012] Figure 3 This is a schematic diagram of a specific embodiment of the cleaning oil supply system of this utility model. Detailed Implementation
[0013] The brushes on existing wiping equipment mostly use a multi-bristle rotating brushing method to clean the inner wall of the gun barrel. When the brush passes through the rifling grooves, it mainly brushes the top of the rifling, and the brushing effect on the bottom of the grooves is limited. Moreover, the residue brushed off is easily carried into the rifling grooves by the brush and is not easy to clean out.
[0014] To address the shortcomings of existing equipment, we improved the gun barrel cleaning machine. First, we designed a dual cleaning mechanism consisting of a wiping head and a cleaning brush. The cotton wiping head wipes away deposits from the inner wall of the gun barrel, reducing the amount of residue falling off. Furthermore, our improved brush head is designed to rotate while also periodically moving up and down. This up-and-down movement of the brush effectively cleans the inside of the rifling grooves. See details below. Figure 1-2 The barrel cleaning machine includes a housing 1, with a cotton cloth cleaning head 2 installed at the top of the housing 1, a power cord connector 3 and a signal cord connector 4 at the tail of the housing 1, and a drive roller 5 on the side wall of the housing 1. A ring-shaped brush mounting area is provided in the middle of the side wall of the housing 1, and several brush mechanisms 6 are evenly installed in the brush mounting area. The brush mechanism 6 includes a rotary motor 7 installed inside the housing 1. The output end of the rotary motor 7 is mounted on a base 8 through a spring 9. The housing 1 is provided with a hole 10 for mounting the base 8. The side wall of the base 8 is provided with a flange 11, and the side wall of the hole 10 is provided with a sinusoidal guide groove 12. The flange 11 is slidably mounted in the guide groove 12. During rotation, the base 8 moves up and down as the position of the flange 11 changes in the guide groove 12. The top of the base 8 is provided with four shafts 13 that rotate freely along the axis. The included angle between adjacent shafts 13 is 90°, and a brush head 14 is fixed on the shaft 13.
[0015] To improve cleaning effectiveness, cleaning oil (a mature, commercially available product) can be used during the cleaning process. Many existing wiping devices lack a spraying mechanism, requiring manual spraying of cleaning oil into the barrel. Some wiping devices do have spraying mechanisms, but their designs are often flawed. We have optimized the spraying mechanism based on the structural characteristics of the brush mechanism 6 described above. (Refer to...) Figure 2 and 3 Each brush mechanism 6 has a spray hole 15 next to it. A liquid storage tank 16 is installed inside the housing 1. The liquid storage tank 16 is connected to the spray hole 15 through a liquid supply pump 17 and a liquid delivery pipe 18. The spray direction of the spray hole 15 is inclined towards one side of the base 8. A baffle plate 19 is provided on the top edge of the base 8. The baffle plate 19 is parallel to the side wall of the base 8.
[0016] In addition, to facilitate remote control of the wiping machine, we have installed a camera 20 at the rear of the housing 1 and a position sensor 21 on the side wall of the housing 1. The camera 20 allows real-time observation of the cleaning effect on the inner wall of the barrel, and the position sensor 21 is used to measure the moving distance of the wiping machine.
[0017] The working process of this wiping machine is as follows: Cleaning oil is injected into the storage tank 16 (the housing 1 has an injection port, not shown in the figure), and the housing 1 is placed into the gun barrel. The drive roller 5 (the motor connected to the drive roller 5 is not shown in the figure) is started, causing the housing 1 to move back and forth within the gun barrel. The rotary motor 7 is started, causing the base 8 to rotate. During the rotation of the base 8, the flange 11 slides within the guide groove 12, thus moving up and down under the influence of the guide groove 12. The brush head 14 moves up and down while rotating, effectively impacting and brushing the inside of the rifling grooves, significantly improving the cleaning effect on deposits inside the rifling grooves. The brush head 14 can rotate automatically on the shaft 13, allowing it to rub against the inner wall of the gun barrel at different angles when in contact, further improving the cleaning effect. During the back-and-forth movement, the cotton cloth wiping head 2 wipes the inner wall of the gun barrel, promptly removing the residue cleaned by the brush head 14. While cleaning and wiping, cleaning oil is sprayed into the barrel through the spray nozzle 15. The spray nozzle 15 sprays directly onto the brush head 14, allowing direct spraying of the cleaning area and saving cleaning oil consumption. Simultaneously, the baffle 19 rotates with the base 8. When it rotates to the side of the spray nozzle 15, it refracts the sprayed cleaning oil, allowing it to also wet the surrounding area. The operator observes real-time images of the barrel's inner wall transmitted by a camera on a monitor and controls the wiping machine to reciprocate cleaning at the target location based on the cleaning effect.
