[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please see Figure 1-5 The present invention provides the following technical solution: a gun barrel detection device, including a base 1, a connecting frame 2 above the base 1, a mounting frame 3 on one side of the connecting frame 2, a camera 4 fixedly connected to the middle of one side of the mounting frame 3, a control module 5 fixedly connected to one end of one side of the mounting frame 3, and a laser radar 6 fixedly connected to the other end of one side of the mounting frame 3. The connecting frame 2 and the mounting frame 3 are connected by a connecting component 7, and the base 1 and the connecting frame 2 are connected by an adjusting component 8. The connecting assembly 7 includes a connecting seat 71, which is fixedly connected to one end of the connecting frame 2. A square insert 72 is tightly inserted into one side of the connecting seat 71. A fixing seat 73 is fixedly connected above the connecting seat 71. A fixing screw 74 is threadedly connected to the middle of the fixing seat 73. A throttle 76 is fixedly connected above the fixing screw 74. A cylindrical fixing block 75 is fixedly connected below the fixing screw 74. A protective assembly 77 is provided on one side of the mounting frame 3.

[0018] Specifically, self-locking casters 9 are symmetrically installed below the base 1.

[0019] By adopting the above technical solution, the self-locking caster wheel 9 facilitates the movement of the device. By rotating the handle 76, the handle 76 drives the fixing screw 74 to rotate, and the fixing screw 74 drives the cylindrical fixing block 75 to move, so that it separates from the fixing hole above the square insert 72. Then, the mounting bracket 3 can be removed by separating the square insert 72 from the connecting seat 71 for inspection and maintenance of the detection components.

[0020] Specifically, a fixing hole is provided on the top of the square insert 72 to match the cylindrical fixing block 75, and the cylindrical fixing block 75 and the fixing hole are tightly inserted.

[0021] By adopting the above technical solution, the fixing hole facilitates tight insertion with the cylindrical fixing block 75 and fixes the square insert block 72.

[0022] Specifically, the protective component 77 includes a protective cover 771, which covers one side of the mounting bracket 3. A limiting seat 772 is fixedly connected to the middle of the upper part of the mounting bracket 3. A limiting rod 773 is slidably connected to the middle of the limiting seat 772. A pull block 774 is fixedly connected to the upper part of the limiting rod 773. Limiting springs 775 are fixedly connected to both ends below the pull block 774. The lower part of the limiting springs 775 is fixedly connected to the limiting seat 772. A positioning block 776 is fixedly connected around and around the surface of the protective cover 771. A limiting hole is opened at the upper end of the protective cover 771 to tightly insert into the limiting rod 773.

[0023] By adopting the above technical solution, the protective cover 771 and the mounting bracket 3 are connected by the positioning block 776, which facilitates the protection of the detection component on one side of the mounting bracket 3 by the protective cover 771. By pulling the pull block 774, the pull block 774 stretches the limit spring 775, which will drive the limit rod 773 to move, so that it separates from the protective cover 771, and then the protective cover 771 can be removed.

[0024] In this embodiment, the self-locking casters 9 facilitate movement of the device. Rotating the handle 76 causes the fixing screw 74 to rotate, which in turn moves the cylindrical fixing block 75, separating it from the fixing hole above the square insert 72. The mounting bracket 3 can then be removed by separating the square insert 72 from the connecting seat 71 for inspection and maintenance of the detection components. The positioning block 776 connects the protective cover 771 to the mounting bracket 3, protecting the detection components on one side of the mounting bracket 3. Pulling the pull block 774 stretches the limiting spring 775, simultaneously moving the limiting rod 773 to separate it from the protective cover 771, allowing it to be removed. This allows for easy assembly and disassembly of the mounting bracket 3 during use, facilitating inspection and maintenance of the detection components. The protective component 77 also protects the detection components when the device is not in use.

[0025] Example 2 The difference between this embodiment and embodiment 1 is that, specifically, the adjustment component 8 includes a support frame 81, which is fixedly connected to the top of the base 1. An adjustment seat 82 is fixedly connected to one side of the support frame 81. An adjustment trapezoidal screw 83 is rotatably connected to the inside of the adjustment seat 82 via a bearing. A DC motor 84 is fixedly connected through the adjustment seat 82 at the bottom of the adjustment trapezoidal screw 83. The bottom of the DC motor 84 is fixedly connected to the base 1. A square slide plate 85 is threadedly connected to the surface of the adjustment trapezoidal screw 83. The square slide plate 85 and the adjustment seat 82 are in close sliding connection. An adjustment frame 86 is fixedly connected to the top of the square slide plate 85. One side of the adjustment frame 86 is in close sliding connection with the adjustment seat 82.

[0026] By adopting the above technical solution, the DC motor 84 is started, which drives the adjusting trapezoidal lead screw 83 to rotate. The rotation of the adjusting trapezoidal lead screw 83 will drive the square slide plate 85 to move. The movement of the square slide plate 85 will drive the adjusting frame 86 to move, thereby driving the detection component to adjust its height through the adjusting frame 86.

[0027] Specifically, a connecting plate 87 is symmetrically and fixedly connected to the side of the adjusting bracket 86 away from the adjusting seat 82. A fixing screw 88 is inserted in the middle of the connecting plate 87, and the fixing screw 88 is threadedly connected to the connecting bracket 2.

[0028] By adopting the above technical solution, the connecting plate 87 and the connecting frame 2 are connected and then fixed by the fixing screw 88, making it easy to splice the adjusting component 8 and the connecting frame 2.

[0029] Specifically, a stop block 89 is fixedly connected to one end of the adjusting trapezoidal lead screw 83 located inside the square slide plate 85.

[0030] By adopting the above technical solution, the stop 89 can easily limit the movement range of the square sliding plate 85.

[0031] In this embodiment, when in use: the DC motor 84 is started, which drives the adjusting trapezoidal lead screw 83 to rotate. The rotation of the adjusting trapezoidal lead screw 83 will drive the square slide plate 85 to move. The movement of the square slide plate 85 will drive the adjusting frame 86 to move. Thus, the height of the detection component is adjusted by the adjusting frame 86. The connecting plate 87 and the connecting frame 2 are connected and then fixed by the fixing screw 88, which makes it easy to splice the adjusting component 8 and the connecting frame 2. This allows the device to easily adjust the height of the detection component during use, and the structure is practical.

[0032] The structure and operating principle of the connecting frame 2, mounting frame 3, camera 4, control module 5, and lidar 6 in this utility model have been disclosed in a gun barrel detection device published in Chinese Patent Publication No. CN221445086U. Its working principle is as follows: the detection component of this utility model measures the gun barrel non-contactly. Rapid response and high-precision measurement are achieved through lidar 6 and camera 4. The signal output terminals of lidar 6 and camera 4 are connected to the signal input terminal of control module 5. Lidar 6 and camera 4 are aligned with the gun barrel. Control module 5 receives data from lidar 6 and camera 4 and matches the image of the gun barrel with the laser beam path of lidar 6 using a machine vision algorithm. The detection component also includes a data analysis device. The data analysis device processes the data from control module 5, analyzes the elevation and low angle data according to a preset algorithm and data processing model, and outputs the elevation and low angle data results.

[0033] The working principle and usage process of this utility model: This utility model is used for detecting artillery barrels. In use, the device is automatically controlled by a controller. The controller's control circuit can be easily programmed by those skilled in the art. During use, the detection component performs non-contact measurement with the artillery barrel. Rapid response and high-precision measurement are achieved through a laser radar 6 and a camera 4. The signal output terminals of the laser radar 6 and camera 4 are connected to the signal input terminal of the control module 5. The laser radar 6 and camera 4 are aligned with the artillery barrel, and the control module 5 receives the data from the laser radar 6 and camera 4. Through machine vision algorithms, the data is processed... The image of the artillery barrel is matched with the laser beam path of the lidar 6. The detection component also includes a data analysis device, which processes the data from the control module 5. Based on a preset algorithm and data processing model, it analyzes the elevation and low angle data and outputs the elevation and low angle data results. The height of the detection component can be easily adjusted by the adjustment component 8, and the detection component can be easily disassembled and assembled by the connection component 7 for easy maintenance. When in use, the self-locking casters 9 facilitate the movement of the device. Rotating the handle 76 drives the fixing screw 74 to rotate, and the fixing screw 74 drives the cylindrical fixing block 75 to move, so that it is aligned with the control module 5. The fixing hole above the square insert 72 is separated, and then the mounting bracket 3 can be removed by separating the square insert 72 from the connecting seat 71 for inspection and maintenance of the detection component. The protective cover 771 and the mounting bracket 3 are connected by the positioning block 776, facilitating protection of the detection component on one side of the mounting bracket 3 through the protective cover 771. By pulling the pull block 774, the pull block 774 stretches the limit spring 775, which simultaneously moves the limit rod 773, separating it from the protective cover 771. The protective cover 771 can then be removed, allowing for convenient disassembly and assembly of the mounting bracket 3 during use, facilitating inspection and maintenance of the detection component. The protective component 77 protects the detection component when the device is not in use. When the adjustment component 8 is in use, the DC motor 84 is started, which drives the adjustment trapezoidal screw 83 to rotate. The rotation of the adjustment trapezoidal screw 83 causes the square slide plate 85 to move, which in turn causes the adjustment frame 86 to move. Thus, the height of the detection component is adjusted by the adjustment frame 86. The connection is made between the adjustment component 8 and the connection frame 2 via the connecting plate 87 and then fixed with the fixing screw 88. This facilitates the splicing of the adjustment component 8 and the connection frame 2, making it easy to adjust the height of the detection component during use. The structure is practical.
