[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0028] like Figure 1 As shown, in one embodiment, a gas cylinder detection device is provided, comprising: a defect detection component 100, a drive mechanism 200 and a control element 400. The defect detection component 100 comprises a first detection head (not shown) for identifying defects; the drive mechanism 200 is used to drive the first detection head to move along a preset track; the control element is electrically connected to the drive mechanism and the first detection head; when the first detection head moves to a first preset position, the control element 400 starts to record the coordinate point of the first detection head relative to the first preset position until the first detection head moves to a position perpendicular to the defect.

[0029] When the gas cylinder detection device of the above embodiment detects the gas cylinder 10, the driving mechanism 200 is used to drive the first detection head to move along the preset track, so that the first detection head can be extended from the outside into the gas cylinder 10 and move inside the gas cylinder 10, and then the first detection head can be used to identify the defect. At the same time, during the movement of the first detection head, when the first detection head moves to pass through the first preset position, the control element 400 starts to record the coordinate points of the first detection head relative to the first preset position during the movement process, until the first detection head moves to the vertical defect setting, so that the position of the defect relative to the first preset position can be accurately marked, providing accurate data support for the inspection and evaluation of the gas cylinder 10 and the subsequent repair.

[0030] It should be noted that the first detection head can be an existing endoscope lens or other element that can identify defects such as cracks, linear deformation or corrosion pits. The control element 400 can be a single-chip microcomputer, a PLC (Programmable Logic Controller) or other device with control function, and the control element 400 can be set on a corresponding workbench. The electrical connection can be achieved through existing wired connection methods such as data cables, or through existing wireless connection methods such as Bluetooth transmission, as long as the signal or information can be transmitted. The first detection head is set perpendicular to the defect, which means that the first detection head is perpendicular to the normal plane where the defect is located. It can be pre-set by the control element to determine whether the first detection head moves to the first preset position; it can also be added with an existing position detection element such as a corresponding position sensor, and the position detection element is used to detect the position of the first detection head and transmit the detected position signal to the control element. When the position detection element detects that the first detection head moves to the first preset position, the corresponding position signal is transmitted to the control element, so that the control element starts to record the coordinate point of the first detection head relative to the first preset position.

[0031] Among them, the first preset position can be flexibly selected according to actual use needs, and it only needs to be able to be used as a reference position to locate the location of subsequent defects.

[0032] In one embodiment, the first preset position is set at the plane position where the mouth of the gas cylinder 10 is located. In this way, when the first detection head passes through the plane where the mouth of the gas cylinder 10 is located, the control element 400 starts to record the coordinate point of the first detection head relative to the plane position where the mouth of the gas cylinder 10 is located, so that the position of the defect can be accurately digitized and marked, which is convenient for the inspection and evaluation of the gas cylinder 10 and the subsequent accurate repair of the defect.

[0033] like Figure 1 As shown, further, the first preset position is set to the intersection position 300 of the central axis of the gas cylinder 10 and the plane where the bottle mouth is located. In this way, the first detection can be set directly above the intersection position 300. When the first detection head descends to the intersection position 300, the control element 400 starts to record the coordinate point of the first detection head relative to the intersection position 300. The moving track of the first detection head is short, which improves the detection efficiency.

[0034] In one embodiment, the defect detection assembly 100 also includes a second detection head (not shown) for detecting the parameters of the defect. In this way, the second detection head can be used to detect the relevant parameters of the defect, thereby providing more accurate data support for the inspection and evaluation of the gas cylinder 10 and the repair or scrapping of the gas cylinder 10. The gas cylinder detection device also includes a first driving member (not shown) connected to the driving mechanism 200. In this way, when the driving mechanism 200 drives the first detection head to move along the preset trajectory, it can simultaneously drive the second detection head to move along the preset trajectory, so that the second detection head can move to the vertical defect setting. The first driving member and the second detection head are both electrically connected to the control element 400, and the first driving member is used to drive the second detection head to move to fit with the inner wall of the gas cylinder 10. In this way, under the drive of the driving mechanism 200, after the second detection head moves to the vertical defect setting, under the drive of the first driving member, the second detection head can move toward the inner wall close to the gas cylinder 10 until the second detection head fits the inner wall of the gas cylinder 10, so that the second detection head can be close to the defect, ensuring that the second detection head can accurately detect the relevant parameters of the defect. The second detection head may be a laser rangefinder probe, so as to detect the depth of the defect. The first driving member may be a pneumatic cylinder, a hydraulic cylinder or other element that can drive the second detection head to move to fit the inner wall of the gas cylinder 10 .

[0035] In one embodiment, the first driving member is configured as a hydraulic cylinder, the second detection head is configured as a laser ranging probe, the laser ranging probe is fixedly mounted on the end of the telescopic rod of the hydraulic cylinder by means of screw connection or clamping, and the hydraulic cylinder is fixedly mounted on the driving mechanism 200 by means of screw connection or riveting. In this way, the driving mechanism 200 drives the hydraulic cylinder to move along a preset track, thereby driving the laser ranging probe to move along the preset track until the laser ranging probe moves to a vertical defect setting, and then uses the extension movement of the telescopic rod of the hydraulic cylinder to drive the laser ranging probe to move toward the inner wall of the gas cylinder 10, until the laser ranging probe fits the inner wall of the gas cylinder 10, so that the laser ranging probe is close to the defect, and then the laser ranging probe can be used to detect the depth of the defect, providing data support for the inspection and evaluation of the gas cylinder 10 and whether the gas cylinder 10 needs to be scrapped.

[0036] Among them, according to the provisions of "Periodic Inspection and Evaluation of Composite Gas Cylinders for Respirators" (GB24161-2009), gas cylinders 10 with pitting corrosion pits greater than 0.7mm in depth, linear corrosion pits greater than 0.5mm in depth, and dispersed pitting corrosion pits greater than 0.5mm in depth should be scrapped. In the traditional manual inspection method, the operator's visual observation and experience are mainly used to judge whether the gas cylinder 10 has reached the scrap standard, which is prone to misjudgment. The above-mentioned gas cylinder detection device can accurately detect the depth of the defect using the second detection head, so as to accurately judge whether the gas cylinder 10 is scrapped.

[0037] It should be noted that the first detection head and the second detection head can also be integrated into one probe, which has a compact structure and saves space. It only needs to be able to identify the defect and detect the parameters of the defect. When the first detection head and the second detection head are two detection heads respectively, the driving mechanism 200 can first drive the first detection head to make the first detection head perpendicular to the defect setting, so as to accurately mark the position of the defect first, and then the driving mechanism 200 drives the second detection head to move to a setting perpendicular to the defect, and then the first driving member drives the second detection head to move to the inner wall setting where the defect is located.

[0038] The driving mechanism 200 drives the first detection head to move along a preset trajectory. This can be achieved through the guiding effect of the guide rail or through the movement of the manipulator. It is only necessary to ensure that the first detection head can be inserted into the gas cylinder 10 to identify defects and that the first detection head can be set vertically to the defects.

[0039] like Figure 1 As shown, in one embodiment, the driving mechanism 200 includes a first transmission assembly 210 for driving the first detection head to reciprocate along the axial direction of the gas cylinder 10, and a second transmission assembly (not shown) for driving the first detection head to rotate around the central axis of the gas cylinder 10. The first transmission assembly 210 and the second transmission assembly are both electrically connected to the control element 400. In this way, the first transmission assembly 210 drives the first detection head to extend into the gas cylinder 10 along the axial direction of the gas cylinder 10 from above the gas cylinder 10, and can drive the first detection head to move up and down along the axial direction in the gas cylinder 10, so as to identify defects; and then the second transmission assembly is used to drive the first detection head to rotate around the central axis of the gas cylinder 10, so that the first detection head can identify and detect defects in multiple directions to avoid omissions, and at the same time, the first detection head can be moved to a normal plane perpendicular to the defect. After the detection is completed, driven by the second transmission assembly and the first transmission assembly 210, the first detection head can move to the outside of the gas cylinder 10 along the original trajectory to prepare for the next detection. The first transmission assembly 210 may be a combination of a gear and a rack, or a telescopic form of a hydraulic cylinder or a pneumatic cylinder, or other existing transmission elements capable of driving the first detection head to reciprocate along the axial direction of the gas cylinder 10. The second transmission assembly may be a rotary motor, or a gear set, or other existing transmission elements capable of driving the first detection head to rotate around the central axis of the gas cylinder 10.

[0040] The position of the defect can be comprehensively indicated by the distance that the first detection head moves downward along the axial direction of the gas cylinder 10 and the angle of rotation relative to the central axis of the gas cylinder 10. When the first preset position is the intersection position 300 of the central axis of the gas cylinder 10 and the plane where the bottle mouth is located, the position of the defect can be directly comprehensively indicated by the depth of the first detection head inserted into the gas cylinder 10 and the angle of rotation relative to the central axis of the gas cylinder 10.

[0041] In one embodiment, there are at least two gas cylinders 10, and the driving mechanism 200 further includes a third transmission assembly (not marked) for driving the first detection head to move along the arrangement direction of the gas cylinders 10, and the third transmission assembly is electrically connected to the control element. In this way, when there are at least two gas cylinders 10, at least two gas cylinders 10 are arranged in sequence in a certain arrangement direction (horizontally, longitudinally, etc.), the third transmission assembly can be used to drive the first detection head to move above each gas cylinder 10, and then the first transmission assembly 210 and the second transmission assembly are used to enable the first detection head to move into each gas cylinder 10, so that each gas cylinder 10 can be detected in sequence, which meets the needs of large-scale detection and has high detection efficiency. Among them, the third transmission assembly can be a guide rail arranged along the arrangement direction of the gas cylinders 10, or a linear motor that can be arranged along the arrangement direction of the gas cylinders 10, or other existing transmission elements that can drive the first detection head to move along the arrangement direction of the gas cylinders 10.

[0042] like Figure 1As shown, in one embodiment, there are six gas cylinders 10, and the six gas cylinders 10 are arranged in sequence in the transverse direction. The third transmission assembly includes a guide rail 230 arranged in the transverse direction and a mechanical arm 220 guided and matched with the guide rail 230, and the mechanical arm 220 can reciprocate along the length direction of the guide rail 230; the first transmission assembly 210 includes a cylinder, the second transmission assembly includes a rotary motor and a turntable arranged on the rotary output end of the rotary motor, and the first driving member includes a hydraulic cylinder. Among them, the cylinder is fixed on the mechanical arm 220 by riveting or clamping, the rotary motor is fixed on the end of the telescopic rod of the cylinder by screwing or clamping, the first detection head is fixed on the turntable by riveting or screwing, the hydraulic cylinder is fixed on the turntable by riveting or screwing, and the second detection head is fixed on the end of the telescopic rod of the hydraulic cylinder by clamping or riveting. The control element 400 is electrically connected to the mechanical arm 220, the cylinder, the rotary motor, and the hydraulic cylinder. The control element 400 can control the robot arm 220 to drive the cylinder to move to the top of each gas cylinder 10. When the control element 400 controls the telescopic rod of the cylinder to extend toward the gas cylinder 10, it drives the rotating motor, the turntable, the hydraulic cylinder, the first detection head and the second detection head to move into the gas cylinder 10. During the extension process of the telescopic rod of the cylinder (of course, it can also be after the telescopic rod of the cylinder is fully extended, during the contraction process of the telescopic rod of the cylinder), the first detection head identifies the defect. When the defect is initially identified, the control element 400 controls the rotating motor to rotate, thereby driving the turntable to rotate, so that the first detection head and the second detection head are both perpendicular to the defect. The arrangement (the first detection head and the second detection head can be) The second detection head 220 is used to detect the deepest depth of the defect, so as to provide data support for whether the gas cylinder 10 meets the scrap standard. After the detection is completed, it returns to the original moving trajectory and resets. The control element 400 can control the robot arm 220 to move to the top of the next gas cylinder 10 to start the detection of the next gas cylinder 10.

[0043] like Figure 1 As shown, based on any of the above embodiments, the gas cylinder detection device further includes a locking mechanism 500, which is used to lock and fix the gas cylinder 10. In this way, the locking mechanism 500 can be used to lock and fix the gas cylinder 10, thereby ensuring that the gas cylinder 10 will not shake or fall during the detection process, thereby ensuring the reliability and accuracy of the detection. Among them, the locking mechanism 500 can be a locking bracket, a locking chuck or other existing mechanisms that can fix the gas cylinder 10.

[0044] On the basis of any of the above embodiments, the gas cylinder detection device further includes a display element (not shown), which is electrically connected to the control element 400. In this way, the display element can be used to display the movement of the first detection head inside the gas cylinder 10, so that the operator can clearly observe the situation inside the gas cylinder 10; and the display element can be used to display the coordinate point of the first detection head relative to the first preset position, which is convenient for recording or observation.

[0045] On the basis of any of the above embodiments, the gas cylinder detection device further includes a light-emitting element (not shown), which is connected to the driving mechanism 200 by means of snap-in, plug-in, etc., and the light-emitting element is electrically connected to the control element 400. In this way, when the driving mechanism 200 drives the first detection head to enter the gas cylinder 10, the light-emitting element can also enter the gas cylinder 10, thereby providing lighting for the detection of the first detection head and the second detection head, thereby ensuring the detection accuracy. Furthermore, the control element 400 can also flexibly adjust the brightness of the light-emitting element according to actual use needs. The light-emitting element can be an element that can emit light, such as an LED (Light Emitting Diode) lamp bead.

[0046] like Figure 2 As shown, in one embodiment, a gas cylinder detection method is also provided, which is applied to the gas cylinder detection device of any of the above embodiments, and includes the following steps: S100, when it is detected that the first detection head moves to the first preset position, the coordinate points of the first detection head relative to the first preset position are recorded until the first detection head moves to the vertical defect setting.

[0047] Specifically, when inspecting the gas cylinder 10, the driving mechanism 200 is used to drive the first inspection head to move along a preset track, so that the first inspection head can be extended from the outside into the gas cylinder 10 and move inside the gas cylinder 10, and then the first inspection head can be used to identify defects. When the first inspection head moves to pass through the first preset position, the control element 400 begins to record the coordinate points of the first inspection head relative to the first preset position during the movement, until the first inspection head moves to a vertical defect setting, so that the position of the defect relative to the first preset position can be accurately marked, providing accurate data support for the inspection and assessment of the gas cylinder 10 and subsequent repairs.

[0048] It should be noted that the first detection head can detect at least one (one, two, three or more) defects in a gas cylinder 10. When the first detection head detects a defect, the control element 400 marks the position of the defect accordingly.

[0049] like Figure 2As shown, in one embodiment, after the first detection head moves to the step of vertical defect setting, it also includes: S200, detecting the parameters of the defect. In this way, the relevant parameters of the defect are detected, thereby providing more accurate data support for the repair or scrapping of the gas cylinder 10.

[0050] Specifically, when the driving mechanism 200 drives the first detection head to move along the preset trajectory, it can simultaneously drive the second detection head to move along the preset trajectory, so that the second detection head can move to the vertical defect setting; after the second detection head moves to the vertical defect setting, under the drive of the first driving member, the second detection head can move toward the inner wall close to the gas cylinder 10 until the second detection head fits the inner wall of the gas cylinder 10, so that the second detection head can be close to the defect, ensuring that the second detection head can accurately detect the relevant parameters of the defect. Among them, the detection of the relevant parameters of the defect can be the detection of the length, depth, width and other parameters of the defect, which only need to be used as the scrapping indicator of the gas cylinder 10; preferably, the depth of the defect is detected, which can accurately reflect whether the gas cylinder 10 needs to be scrapped.

[0051] The gas cylinder detection method of the above embodiment has at least the following advantages: 1. It can accurately mark the position of the defect inside the gas cylinder 10, providing data support for the subsequent repair of the gas cylinder 10; 2. It can accurately detect the relevant parameters of the defect, providing accurate data support for the inspection and evaluation of the gas cylinder 10 and whether the gas cylinder 10 needs to be scrapped.

[0052] In one embodiment, a gas cylinder 10 detection system is further provided, comprising the gas cylinder detection device of any one of the above embodiments.

[0053] The gas cylinder 10 detection system of the above-mentioned embodiment can accurately mark the position of the defect inside the gas cylinder 10 when detecting the gas cylinder 10, providing data support for the subsequent repair of the gas cylinder 10; it can also accurately detect the relevant parameters of the defect, providing accurate data support for the inspection and evaluation of the gas cylinder 10 and whether the gas cylinder 10 needs to be scrapped.
