Description

Technical Field

[0001] The invention belongs to the technical field of quality detection, and in particular relates to a fire extinguisher bottle quality detection device and a detection method thereof. Background Art

[0002] The fire extinguisher bottle needs to withstand pressure, especially after the fire extinguisher is filled with fire extinguishing agent, the pressure inside the bottle is usually very high. If the bottle is cracked, corroded or aged, it may not be able to withstand the pressure and may rupture or explode. Through pressurization testing, the strength of the bottle can be checked to ensure that it will not rupture during use. At the same time, since the fire extinguisher bottle needs to maintain good sealing to prevent leakage of fire extinguishing agent, pressurization testing can simulate the actual state of the fire extinguisher under high pressure conditions, thereby testing the sealing of the bottle.

[0003] Chinese patent application number 201110150049.1 proposes a CO 2 The free-style water pressure test equipment for fire extinguisher cylinders includes an equipment body and an equipment working area. The equipment body and the equipment working area are frame structures. A control panel is installed on the equipment body. The frame of the equipment working area is fixed to the equipment body through a rotating shaft. A jacking device is fixedly connected to the bottom of the frame of the equipment working area. A cylinder locking device is fixed to the top of the frame of the equipment working area. A special quick connector is provided at the bottom of the cylinder locking device. A lifting and pressure relief device is fixed above the cylinder locking device. An alarm device is provided next to the lifting and pressure relief device. The cylinder locking device is connected to the lifting and pressure relief device through a pipeline. The equipment meets the requirements of domestic and foreign standards. The cylinder is not subject to external force during the test, so the detection quality is high, which solves the CO 2 The structure and testing method of the free-style water pressure testing equipment for fire extinguisher cylinders have the problem of external pressure application.

[0004] Although the above scheme can meet the water pressure test requirements for fire extinguisher cylinders, there are still some problems. It only evaluates the quality of the cylinder by observing whether there are water seepage points in the cylinder after the water pressure test. If there are defects in the cylinder before the water pressure test, the water pressure test may be inaccurate. At the same time, it lacks the appearance detection of the cylinder after the water pressure test to further comprehensively evaluate the quality of the cylinder after the water pressure test.

[0025] A method for detecting the quality of a fire extinguisher bottle, using the above-mentioned fire extinguisher bottle quality detection device, comprises the following steps:

[0026] S1. The relevant technician starts the third linear motion member to push the arc push block to perform linear motion, so that the two arc push blocks are docked. At this time, the bottle body is placed above the arc push block, and the second linear motion member is started to push the arc push plate to contact the bottle body to straighten and limit the bottle body. At this time, the first linear motion member is started to push the frame to drive the mounting seat to move upward, and then drive the bottle body to move upward, so that the bottle body contacts the connecting pipe column, the connecting pipe column is inserted into the bottle mouth, and the third linear motion member drives the arc push block to reset;

[0027] S2, start the second motor to drive the first flat gear to rotate in the vertical direction, the first flat gear pushes the open ring tube to rotate in the vertical direction through the incomplete gear meshing with it, and then drives the bottle body to rotate in the vertical direction, and because the connecting tube column has space to float up and down under the action of the elastic support component, the connecting tube column is gradually screwed into the bottle body until the bottle mouth of the bottle body hits the rubber sealing ring installed on the connecting tube column, that is, the buckling process of the bottle body and the connecting tube column is completed, and then the sealing connection between the connecting tube column and the bottle body is achieved, and the bottle body is suspended in the air, prompting the limit assembly and the mounting seat to reset;

[0028] S3, using the third linear motion member to push the visual inspection device close to the left and right sides of the bottle body, at this time, using the position adjustment component to drive the visual inspection device to move linearly upward, record the image captured by the visual inspection device during the movement and upload it to the external terminal, when the visual inspection device moves to the uppermost end, start the third motor to drive the second flat gear to rotate, the second flat gear drives the third flat gear to drive the visual inspection device to rotate at an angle of ninety degrees, so that the two visual inspection devices are located at the front and back sides of the bottle body, at this time, the position adjustment component pulls the visual inspection device to move downward along the length direction of the bottle body, and records the image captured by the visual inspection device during the movement of the visual inspection device and uploads it to the external terminal, the external terminal analyzes the image captured by the visual inspection device, and then determines whether the bottle body has defects;

[0029] S4. If the surface of the bottle body is not smooth and has deformation defects, start the buckle mechanism to remove the bottle body from the connecting pipe column and place it in the bad product area. If the product does not have defects, water is injected into the bottle body through the connecting pipe column. After water injection, the connecting pipe column is connected to the pressurizing device through the external rotary adapter and pressurized inside the bottle body. After pressurizing to the rated pressure, the fourth motor is started to drive the rotating shaft to rotate, and the rotating shaft drives the worm to rotate synchronously. The worm drives the rotating drum to rotate in the vertical direction through the worm gear meshing therewith, thereby driving the bottle body connected to the connecting pipe column to rotate in the vertical direction, so that the technicians can observe whether there is liquid seepage around the circumference of the bottle body. If there is liquid seepage, it indicates that the sealing quality of the bottle body is unqualified. Then, the corresponding buckle mechanism is started, and the unqualified bottle body is removed and placed in the bad product area. If there is no liquid seepage, it indicates that the sealing quality of the bottle body is qualified.

[0030] S5. For bottles with qualified sealing quality, the detection component is started again to detect their smoothness, and then determine whether there are defects on the surface of the bottle after the pressurization test. If there are defects, it means that the quality of the bottle is unqualified and the bottle is removed by the buckle mechanism and placed in the bad product area. If there are no defects, the product is removed by the buckle mechanism and placed in the qualified product area and the water in the bottle is drained out.

[0031] The present invention provides a fire extinguisher bottle quality detection device and detection method thereof, which have the following beneficial effects compared with the prior art:

[0032] 1. The present invention can utilize the buckling mechanism in conjunction with the elastic support assembly to automatically buckle the bottle body onto the connecting pipe column, thereby completing a rapid and automatic sealing connection between the bottle body and the connecting pipe column;

[0033] 2. The present invention can use the detection component in conjunction with the buckle mechanism to detect the quality of the bottle before and after the pressure test on the bottle, thereby improving the pressure test efficiency and detection accuracy of the bottle;

[0034] 3. The rotating assembly provided in the present invention can not only serve as a driving source for driving the rotating drum to drive the bottle body in the vertical direction, but also can limit the rotating drum by its own self-locking property, so as to cooperate with the buckling mechanism and the elastic support assembly to complete the buckling process between the bottle body and the connecting pipe column.

[0048] The buckling mechanism includes a mounting seat 601 and further includes:

[0049] The position adjustment component 602 is installed on the mounting base 601 and is used to push the mounting base 601 to perform linear motion in the vertical direction or to push the mounting base 601 to rotate in the horizontal direction;

[0050] The second rotating assembly 603 is mounted on the mounting seat 601 and is used to drive the bottle body to rotate in the vertical direction, including an open ring cylinder 6031. The open ring cylinder 6031 is rotatably mounted on the mounting seat 601, and also includes:

[0051] The limiting component 6032 is installed on the mounting seat 601 and is used to limit the bottle body;

[0052] The pushing component 6033 is installed on the mounting seat 601 and is used to cooperate with the limiting component 6032 to push the bottle body to rotate in the vertical direction;

[0053] The pushing assembly 6033 includes a second motor 60331, a first flat gear 60332 and an incomplete gear 60333. The two second motors 60331 are symmetrically and detachably mounted on the mounting seat 601. The first flat gear 60332 is fixedly connected to the output shaft of the second motor 60331 and meshes with the incomplete gear 60333 fixedly connected to the open ring cylinder 6031. The bottle body is limited in the inner circle of the open ring cylinder 6031 by the limiting assembly 6032. At this time, the second motor 60331 drives the first flat gear 60332 to push the open ring cylinder 6031 to rotate in the vertical direction, thereby pushing the bottle body to rotate in the vertical direction.

[0054] Among them, the limiting component 6032 includes a second linear moving part 60322, and three of the second linear moving parts 60322 are embedded in an annular shape and installed in the open ring cylinder 6031. An arc-shaped push plate 60321 is fixedly connected to the output shaft of the second linear moving part 60322. The purpose of this arrangement is to use the second linear moving part 60322 to push the arc-shaped push plate 60321 to perform linear motion. The three arc-shaped push plates 60321 achieve the technical effect of clamping and limiting the bottle body by performing synchronous centripetal motion.

[0055] Among them, the position adjustment component 602 includes a frame 6021, a first linear moving part 6022 and a first motor 6023. The first linear moving part 6022 can be detachably installed on the frame 1. The frame 6021 is fixedly connected to the output shaft of the first linear moving part 6022. The first motor 6023 is installed in the frame 6021 and its output shaft passes through the front end of the frame 6021 and is fixedly connected to the mounting seat 601. The purpose of this setting is to use the first linear moving part 6022 to push the frame 6021 to perform linear movement in the vertical direction, and use the first motor 6023 to drive 602 to rotate in the horizontal direction, so as to achieve the technical effect of adjusting the height of the mounting seat 601 and rotating it in the horizontal direction.

The meshing worm gear 501 drives the drum 3 to rotate in the vertical direction, thereby pushing the connecting tube column 2 installed on the drum 3 through the elastic support component 4 to rotate in the vertical direction, thereby driving the bottle body installed on the connecting tube column 2 to rotate in the vertical direction, so that personnel can observe whether there is liquid leakage in the bottle body filled with water after pressurization, and then detect the sealing of the bottle body. At the same time, since the first rotating component 5 is a worm gear mechanism with self-locking properties, that is, the worm can only push the worm wheel to rotate, and the worm wheel cannot push the worm to rotate in the opposite direction, that is, the drum 3 will not rotate when the buckling mechanism is buckled.

[0057] Among them, the elastic support assembly 4 includes a support rod 401, a sleeve 402 and a mounting plate 403, the mounting plate 403 is sleeved on the upper end of the connecting pipe column 2 and fixedly connected to the connecting pipe column 2, the lower end of the sleeve 402 is fixedly connected to the rotating drum 3, one end of the support rod 401 extends into the sleeve 402 and slidably cooperates with the sleeve 402, an elastic member (not marked in the figure) for elastically supporting the support rod 401 is installed in the sleeve 402, and the upper end of the support rod 401 is fixedly connected to the mounting plate 403. The purpose of this arrangement is to utilize the mutual cooperation of the support rod 401, the sleeve 402, the mounting plate 403 and the elastic member to elastically support the connecting pipe column 2, thereby enabling the connecting pipe column 2 to have a floating space.

[0058] The detection assembly includes a mounting ring 901, an arc-shaped push block 902, a third linear motion member 903, a third motor 904, a second flat gear 905, a third flat gear 906, a visual detection device 907, and an L-shaped plate 908. The mounting ring 901 is rotatably mounted at the lower end of the mounting seat 601, and two L-shaped plates 908 are symmetrically mounted on the mounting ring 901. The third linear motion member 903 is mounted on the L-shaped plate 908. The output end of the third linear motion member 903 is fixedly connected to an arc The arc-shaped push block 902 is embedded with a visual detection device 907, the mounting ring 901 is sleeved with a third flat gear 906 and the third flat gear 906 is fixedly connected to the mounting ring 901, the third motor 904 is detachably mounted on the mounting seat 601, and the output shaft of the mounting seat 601 is fixedly connected with a second flat gear 905 meshing with the third flat gear 906. The purpose of this arrangement is to use the position adjustment component 602 to cause the mounting seat 601 to flip and cause the arc-shaped push block 90 2 is located above, the open ring cylinder 6031 is located below, and the visual inspection device 907 is caused to be located on the left and right sides of the bottle body. At this time, the third linear motion member 903 is used to push the visual inspection device 907 close to the left and right sides of the bottle body. At this time, the position adjustment component 602 is used to drive the visual inspection device 907 to move linearly upward, record the image captured by the visual inspection device 907 during the movement and upload it to the external terminal. When the visual inspection device 907 moves to the uppermost end, the third motor 904 is started to drive the second flat gear 905 to rotate, and the second flat gear 905 drives the third flat gear 906 to drive the visual inspection device 907 to rotate at an angle of ninety degrees, so that the two visual inspection devices 907 are located at the front and rear sides of the bottle body. At this time, the position adjustment component 602 pulls the visual inspection device 907 to move downward along the length direction of the bottle body, and records the image captured by the visual inspection device 907 during the movement and uploads it to the external terminal. The external terminal analyzes the image captured by the visual inspection device 907, and then determines whether the bottle body has defects.

[0059] In the embodiment of the present invention, the relevant technicians start the third linear motion member 903 to push the arc push block 902 to perform linear motion, so that the two arc push blocks 902 are docked. At this time, the bottle body is placed above the arc push block 902, and the second linear motion member 60322 is started to push the arc push plate 60321 to contact the bottle body, so as to straighten and limit the bottle body. At this time, the first linear motion member 6022 is started to push the frame 6021 to drive the mounting seat 601 to move upward, thereby driving the bottle body to move upward, so that the bottle body contacts the connecting column 2, so that the connecting column 2 is inserted into the bottle mouth of the bottle body and the third linear motion member 903 drives the arc push block 902 to reset. At this time, the second motor 60331 is started to drive the first flat gear 60332 to rotate in the vertical direction.The first flat gear 60332 pushes the open ring cylinder 6031 to rotate in the vertical direction through the incomplete gear 60333 meshing therewith, thereby driving the bottle body to rotate in the vertical direction. Since the connecting column 2 has space to float up and down under the action of the elastic support component 4, the connecting column 2 is gradually screwed into the bottle body until the bottle mouth of the bottle body hits the rubber sealing ring 7 installed on the connecting column 2, thus completing the buckling process of the bottle body and the connecting column 2, thereby achieving a sealed connection between the connecting column 2 and the bottle body. At this time, the bottle body is suspended, prompting the limit component 6032 and the mounting seat 601 to reset, and starting the first motor 6023 to drive 602 to rotate in the horizontal direction, prompting the arc-shaped push block 902 to be located at the top and the open ring cylinder 603 1 is located at the bottom, at this time, the third linear motion member 903 pushes the visual detection device 907 to approach the left and right sides of the bottle body, and at this time, the position adjustment component 602 is used to drive the visual detection device 907 to move linearly upward, and the image captured by the visual detection device 907 during the movement is recorded and uploaded to the external terminal. When the visual detection device 907 moves to the uppermost end, the third motor 904 is started to drive the second flat gear 905 to rotate, and the second flat gear 905 drives the third flat gear 906 to drive the visual detection device 907 to rotate at an angle of 90 degrees, so that the two visual detection devices 907 are located at the front and rear sides of the bottle body. At this time, the position adjustment component 602 pulls the visual detection device 907 to move downward along the length direction of the bottle body, and records the visual detection device 9 07 records the image captured by the visual inspection device 907 during the movement and uploads it to the external terminal. The external terminal analyzes the image captured by the visual inspection device 907 to determine whether the bottle has defects. If the surface of the bottle is not smooth and has deformation defects, the buckle mechanism is activated to remove the bottle from the connecting column 2 and place it in the defective product area. If the product has no defects, water is injected into the bottle through the connecting column 2. After water injection, the connecting column 2 is connected to the pressurizing device through the external rotary adapter and pressurized inside the bottle. After pressurizing to the rated pressure, the fourth motor is started to drive the rotating shaft 503 to rotate, and the rotating shaft 503 drives the worm 502 to rotate synchronously. The worm 502 drives the rotating drum 3 to rotate in the vertical direction through the worm gear 501 meshing therewith. This will drive the bottle body connected to the connecting tube column 2 to rotate in the vertical direction, so that the technicians can observe whether there is liquid seepage around the bottle body. If there is liquid seepage, it indicates that the sealing quality of the bottle body is unqualified, and the corresponding buckle mechanism is activated to remove the unqualified bottle body and place it in the bad product area. If there is no liquid seepage, it indicates that the sealing quality of the bottle body is qualified. For the bottle body with qualified sealing quality, the detection component is started again to detect its smoothness, and then it is determined whether there are defects on the surface of the bottle body after the pressurization test (whether there are protrusions or bulges). If there are defects, it indicates that the quality of the bottle body is unqualified and the buckle mechanism is used to remove the bottle body and place it in the bad product area. If there are no defects, the buckle mechanism is used to remove the product and place it in the qualified product area and the water in the bottle is drained out.

[0060] A method for detecting the quality of a fire extinguisher bottle is provided, using the above-mentioned fire extinguisher bottle quality detection device for detection, comprising the following steps:

[0061] S1. The relevant technician starts the third linear motion member 903 to push the arc push block 902 to perform linear motion, so that the two arc push blocks 902 are docked. At this time, the bottle body is placed above the arc push block 902, and the second linear motion member 60322 is started to push the arc push plate 60321 to contact the bottle body, and the bottle body is corrected and limited. At this time, the first linear motion member 6022 is started to push the frame 6021 to drive the mounting seat 601 to move upward, and then drive the bottle body to move upward, so that the bottle body contacts the connecting column 2, the connecting column 2 is inserted into the bottle mouth, and the third linear motion member 903 drives the arc push block 902 to reset;

[0062] S2, start the second motor 60331 to drive the first flat gear 60332 to rotate in the vertical direction, and the first flat gear 60332 pushes the open ring cylinder 6031 to rotate in the vertical direction through the incomplete gear 60333 meshing with it, thereby driving the bottle body to rotate in the vertical direction. Since the connecting column 2 has space to float up and down under the action of the elastic support component 4, the connecting column 2 is gradually screwed into the bottle body until the bottle mouth of the bottle body hits the rubber sealing ring 7 installed on the connecting column 2, that is, the buckling process of the bottle body and the connecting column 2 is completed, thereby achieving a sealed connection between the connecting column 2 and the bottle body. At this time, the bottle body is suspended in the air, prompting the limit component 6032 and the mounting seat 601 to reset;

[0063] S3, using the third linear motion member 903 to push the visual inspection device 907 close to the left and right sides of the bottle body, at this time, using the position adjustment component 602 to drive the visual inspection device 907 to move linearly upward, record the image captured by the visual inspection device 907 during the movement and upload it to the external terminal, when the visual inspection device 907 moves to the uppermost end, start the third motor 904 to drive the second flat gear 905 to rotate, the second flat gear 905 drives the third flat gear 906 to drive the visual inspection device 907 to rotate at an angle of ninety degrees, so that the two visual inspection devices 907 are located at the front and rear sides of the bottle body, at this time, the position adjustment component 602 pulls the visual inspection device 907 to move downward along the length direction of the bottle body, and records the image captured by the visual inspection device 907 during the movement of the visual inspection device 907 and uploads it to the external terminal, the external terminal analyzes the image captured by the visual inspection device 907, and then determines whether there is a defect in the bottle body;

[0064] S4. If the surface of the bottle body is not smooth and has deformation defects, the buckle mechanism is started to remove the bottle body from the connecting column 2 and place it in the bad product area. If the product does not have defects, water is injected into the bottle body through the connecting column 2. After water injection, the connecting column 2 is connected to the pressurizing device through the external rotary adapter and pressurized inside the bottle body. After pressurization to the rated pressure, the fourth motor is started to drive the rotating shaft 503 to rotate, and the rotating shaft 503 drives the worm 502 to rotate synchronously. The worm 502 drives the rotating drum 3 to rotate in the vertical direction through the worm gear 501 meshing therewith, thereby driving the bottle body connected to the connecting column 2 to rotate in the vertical direction, so that the technicians can observe whether there is liquid seepage around the bottle body. If there is liquid seepage, it indicates that the sealing quality of the bottle body is unqualified. Then, the corresponding buckle mechanism is started to remove the unqualified bottle body and place it in the bad product area. If there is no liquid seepage, it indicates that the sealing quality of the bottle body is qualified.

[0065] S5. For bottles with qualified sealing quality, the detection component is started again to detect their smoothness, and then determine whether there are defects on the surface of the bottle after the pressurization test. If there are defects, it means that the quality of the bottle is unqualified and the bottle is removed by the buckle mechanism and placed in the bad product area. If there are no defects, the product is removed by the buckle mechanism and placed in the qualified product area and the water in the bottle is drained out.
