Description

Technical Field

[0001] The present invention relates to the technical field of airtightness detection, and specifically to a fault diagnosis device that is convenient for installing and replacing detection probes. Background Technique

[0002] Fault diagnosis devices play a crucial role in many fields such as modern industrial production, transportation, and medical care. They are used to detect, locate, and analyze faults that occur in various devices or systems to ensure their safe and stable operation. Physical quantities during the operation of the device, such as parameters like temperature, pressure, vibration, current, and voltage, are collected in real time through various sensors. Among the common fault diagnosis devices in sealed devices is the airtightness detection device. An airtightness detection device is an instrument used to detect whether an object or system has leaks to ensure its airtightness. Usually, the differential pressure method or the direct pressure method is used for detection. The direct pressure method is to directly fill the workpiece to be measured with a certain pressure of gas. After a stable time, the pressure change inside the workpiece is measured to determine whether there is a leak.

[0003] In existing airtightness detection devices, in order to adapt to openings of different sizes in the container, a clamping connection method is usually adopted. However, the clamping position is usually only sealed with a rubber pad, resulting in air leakage after the air pressure increases. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] A fault diagnosis device that is convenient for installing and replacing detection probes, including:

[0006] A frame body, on the top of which a cylinder and an air pump are fixedly installed. The output end of the cylinder penetrates the frame body and extends to its interior;

[0007] A fixing mechanism, which is installed at the central position inside the frame body. A display is installed inside the frame body;

[0008] The output end of the cylinder is fixedly installed with a connecting plate, and the bottom of the connecting plate is fixedly installed with a clamping cylinder;

[0009] A sealing mechanism, which is installed at the bottom of the clamping cylinder and is used to connect to the position of the container interface to be detected. An air pressure sensor is installed on the inner wall of the sealing mechanism, and the air pressure sensor is electrically connected to the display;

[0010] The sealing mechanism further includes a cover cylinder. The top of the cover cylinder is fixedly installed with a buckling cylinder. Buckling blocks are uniformly arranged at the top of the inner wall of the buckling cylinder, and an inner groove plate is fixedly installed at the bottom of the inner wall of the buckling cylinder. A ring groove is arranged on the top of the inner groove plate;

[0011] At the bottom of the outer side of the cartridge, clamping blocks are uniformly arranged. The cartridge is clamped with the clamping blocks of the buckle cylinder through the clamping blocks. A rubber ring is fixedly installed at the bottom of the cartridge, and the rubber ring corresponds to the ring groove of the inner groove plate. During the connection process through the cooperation of the cartridge and the buckle cylinder, the clamping blocks of the cartridge are clamped with the clamping blocks of the buckle cylinder. When detecting containers of different sizes, the air pressure sensor is replaced simultaneously with the sealing mechanism, accelerating the replacement speed of the detection probe. At the same time, the air pressure sensor is quickly installed with the sealing mechanism through clamping. During the clamping process, through the cooperation of the rubber ring and the ring groove of the inner groove plate, the rubber ring and the inner groove plate are closely fitted during the clamping process. During the detection process, with the pressure applied by the cylinder, the fitting pressure between the rubber ring and the inner groove plate is increased again. At the same time, the ring groove limits the deformation range of the rubber ring, improving the sealing performance of the clamping position and avoiding air leakage during the airtightness detection, which may lead to incorrect detection results. At the top of the inner wall of the cartridge, a rubber cylinder is clamped. A card slot is opened at the bottom end of the rubber cylinder, and a sliding ring is clamped at the bottom end of the rubber cylinder through the card slot. A joint is fixedly installed on the inner wall of the sliding ring, and the top end of the joint is connected to an air pump through a pipeline.

[0012] Preferably, the inner wall of the rubber cylinder is closely fitted with the outer side of the joint, and the outer side of the rubber cylinder is closely fitted with the inner wall of the cartridge. The outer side of the sliding ring is slidably adapted to the inner wall of the cartridge, and an inner groove ring groove is opened at the bottom of the sliding ring. Through the inner groove ring groove of the sliding ring, the contact area with the gas is increased. When the internal air pressure increases and the joint shows a tendency to be ejected, the joint presses the rubber cylinder through the sliding ring, causing the rubber cylinder to show a tendency to deform between the joint and the cartridge. While increasing the fitting pressure, the ejection of the joint is restricted, ensuring the connection of the gas path during the pressurization process, ensuring the airtightness of the equipment during detection, and avoiding air leakage. The cover cylinder is a conical cover with the inner diameter and outer diameter gradually decreasing from top to bottom. A sliding groove is opened on the outer side of the cover cylinder. A sliding cover is slidably installed at the sliding groove of the cover cylinder. A gasket ring is clamped between the bottom end of the cover cylinder and the sliding cover. The bottom end of the sliding cover is fixedly installed with a bottom sliding cylinder, and the bottom end of the bottom sliding cylinder inclines inward, and an arc-shaped pad is fixedly installed at the bottom end of the bottom sliding cylinder.

[0013] Preferably, both the arc-shaped pad and the pad ring are made of rubber material. The top of the outer side of the cover cylinder is fixedly connected to a pressure sensor. Through the cooperation of the arc-shaped pad and the pad ring, and by utilizing the characteristics of rubber deformation, during the process of the cylinder driving the pressure application, it cooperates with the fixing mechanism to adjust the position of the container. At the same time, the arc-shaped pad utilizes the characteristics of rubber deformation after contacting the container to improve the fit with the container, and forms a seal on the outside of the container opening, realizing double-layer sealing treatment to ensure the accuracy of airtightness detection. The detection end of the pressure sensor penetrates through the cover cylinder and extends to the inside. There is an annular protrusion at the bottom of the inner wall of the cover cylinder, and a hollow cylinder is slidably installed on the inner wall of the annular protrusion. An outer pad ring is fixedly installed at the top of the outer side of the hollow cylinder, and a conical mask is fixedly installed at the bottom end of the hollow cylinder. The inner diameter of the conical mask gradually increases from top to bottom. The outer pad ring is made of rubber material, and the outer side of the outer pad ring is closely attached to the inner wall of the cover cylinder.

[0014] Preferably, the fixing mechanism includes a fixing ring. The bottom of the fixing ring is fixedly connected to the frame body, and a tray is slidably installed at the top of the inner wall of the fixing ring. A connecting ring is fixedly installed at the center position of the top of the tray. A support rod is fixedly installed at the top of the connecting ring. The end of the support rod away from the connecting ring inclines inward, and the support rods are evenly installed along the center position of the connecting ring. A spherical block is fixedly installed at the top end of the support rod. Through the shape of the spherical block, when contacting the bottom of the container, the contact area with the container is reduced, the friction force is lowered, and it cooperates with the downward movement of the pressure ring after being stressed, reducing the resistance during the position adjustment of the container and ensuring the smooth position adjustment of the container. A pressure ring is fixedly installed at the bottom of the tray, and a bottom pad ring is fixedly installed at the bottom of the pressure ring.

[0015] Preferably, rotation grooves are evenly opened at the top of the fixing ring, and rotating blocks are rotatably installed at the rotation groove positions of the fixing ring. A fixing plate is fixedly installed at the top end of the rotating block. A clamping groove plate is fixedly installed at the end of the fixing plate away from the rotating block. An inner cushion block is fixedly installed on the outer side of the clamping groove plate. Inner convex blocks are fixedly installed at the bottom of the opposite surfaces of the rotating blocks. The end of the inner convex block away from the rotating block contacts the bottom of the pressure ring. The bottom pad ring is made of an elastic material. Through the bottom pad ring and the inner convex blocks, during the compression process, the bottom pad ring deforms, causing the pressure ring to press down, and driving the rotating block to rotate through the inner convex block, making the inner cushion block contact the outside of the container, adjusting the position of the container offset from the docking center, making the container opening position correspond to the equipment docking position, and avoiding the inability to perform airtightness detection due to the offset of the joint and the inability to dock. The end of the fixing plate away from the rotating block inclines inward. The surface of the clamping groove plate away from the fixing plate is an inclined surface that inclines inward from top to bottom. The outer side of the inner cushion block is an arc surface with a central protrusion.

[0016] The present invention provides a fault diagnosis device that is convenient for installing and replacing a detection probe. It has the following beneficial effects:

[0017] 1. The fault diagnosis device facilitating the installation and replacement of detection probes, through the cooperation of the clamping cylinder and the buckling cylinder, during the connection process, the clamping block of the clamping cylinder is clamped with the buckling block of the buckling cylinder. When detecting containers of different sizes, the air pressure sensor is replaced simultaneously with the sealing mechanism, accelerating the replacement speed of the detection probe. At the same time, during the clamping process, the air pressure sensor is quickly installed with the sealing mechanism through clamping. Meanwhile, during the clamping process, through the cooperation of the rubber ring and the annular groove of the inner groove plate, the rubber ring is closely attached to the inner groove plate during the clamping process. And during the detection process, with the pressure applied by the air cylinder, the fitting pressure between the rubber ring and the inner groove plate is increased again. At the same time, the annular groove limits the deformation range of the rubber ring, improving the sealing performance of the clamping position and avoiding incorrect detection results caused by air leakage during the airtightness detection process.

[0018] 2. The fault diagnosis device facilitating the installation and replacement of detection probes, through the inner groove annular groove of the slip ring, increases the contact area with the gas. When the internal air pressure increases and the joint shows a tendency to be ejected, the joint presses on the rubber cylinder through the slip ring, causing the rubber cylinder to have a deformation tendency between the joint and the clamping cylinder. While increasing the fitting pressure, it restricts the ejection of the joint, ensuring the connection of the gas path during the pressurization process, ensuring the airtightness of the device during detection, and avoiding air leakage.

[0019] 3. The fault diagnosis device facilitating the installation and replacement of detection probes, through the cooperation of the arc-shaped pad and the pad ring, utilizing the characteristics of rubber deformation, during the process of the air cylinder driving the pressure application, in cooperation with the fixing mechanism, adjusts the position of the container. At the same time, after the arc-shaped pad contacts the container, it utilizes the characteristics of rubber deformation to improve the fitting degree with the container, forming a seal again on the outside of the container opening, realizing double-layer sealing treatment, and ensuring the accuracy of the airtightness detection.

[0020] 4. The fault diagnosis device facilitating the installation and replacement of detection probes, through the shape of the spherical block, when contacting the bottom of the container, reduces the contact area with the container, reduces the friction force, and in cooperation with the downward movement of the pressure ring after being stressed, reduces the resistance during the position adjustment of the container, ensuring the smooth position adjustment of the container.

[0021] 5. The fault diagnosis device facilitating the installation and replacement of detection probes, through the bottom pad ring and the inner convex block, during the compression process, the bottom pad ring deforms, causing the pressure ring to press down, and driving the rotating block to rotate through the inner convex block, making the inner cushion block contact the outside of the container, adjusting the position of the container that is offset from the docking center, making the container opening position correspond to the device docking position, and avoiding the inability to perform airtightness detection due to the offset of the joint and the inability to dock.

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] A frame body 1, on the top of which a cylinder 6 and an air pump 7 are fixedly installed. The output end of the cylinder 6 penetrates through the frame body 1 and extends to its interior;

[0037] A fixing mechanism 2, which is installed at the central position inside the frame body 1, and a display 5 is installed inside the frame body 1;

[0038] The fixing mechanism 2 includes a fixing ring 201, the bottom of the fixing ring 201 is fixedly connected to the frame body 1, and a tray 204 is slidably installed at the top of the inner wall of the fixing ring 201. A connecting ring 206 is fixedly installed at the central position of the top of the tray 204, and a support rod 207 is fixedly installed at the top of the connecting ring 206. One end of the support rod 207 away from the connecting ring 206 inclines inwards. Workers put the opening of the container upwards, so that the bottom of the container is contacted by the spherical block 208 at the top of the support rod 207, and the spherical block 208 supports the container under the restriction of the support rod 207. During the downward movement of the cylinder 6, after the sealing mechanism 3 contacts the container, under the pressure of the cylinder 6, the tray 204 compresses the bottom cushion ring 211 through the pressing ring 203 to deform, so that the tray 204 and the pressing ring 203 move downward, and the support rods 207 are uniformly installed along the center position of the connecting ring 206. The top end of the support rod 207 is fixedly installed with a spherical block 208, the bottom of the tray 204 is fixedly installed with a pressing ring 203, and the bottom of the pressing ring 203 is fixedly installed with a bottom cushion ring 211;

[0039] The output end of the cylinder 6 is fixedly installed with a connecting plate 4, and a clamping cylinder 10 is fixedly installed at the bottom of the connecting plate 4;

[0040] A sealing mechanism 3, which is installed at the bottom of the clamping cylinder 10 and is used to connect to the container interface position to be detected. An air pressure sensor 8 is installed on the inner wall of the sealing mechanism 3, and the air pressure sensor 8 is electrically connected to the display 5;

[0041] The sealing mechanism 3 further includes a cover cylinder 301, a buckling cylinder 302 is fixedly installed at the top of the cover cylinder 301. Buckling blocks are uniformly arranged at the top of the inner wall of the buckling cylinder 302, and an inner groove plate 304 is fixedly installed at the bottom of the inner wall of the buckling cylinder 302. A ring groove is arranged at the top of the inner groove plate 304;

[0042] At the bottom of the outer side of the cartridge case 10, clamping blocks are evenly arranged. The cartridge case 10 is clamped with the clamping blocks of the buckle barrel 302 through the clamping blocks. A rubber ring 13 is fixedly installed at the bottom of the cartridge case 10, and the rubber ring 13 corresponds to the annular groove of the inner groove plate 304. At the top of the inner wall of the cartridge case 10, a rubber cylinder 11 is clamped. A clamping groove is opened at the bottom end of the rubber cylinder 11. When the cartridge case 10 is clamped with the sealing mechanism 3, through the cooperation of the clamping blocks on the outer side of the cartridge case 10 and the clamping blocks on the inner wall of the buckle barrel 302, the cartridge case 10 and the buckle barrel 302 are clamped. At the same time, during the clamping process, through the cooperation of the inner groove plate 304 on the inner wall of the buckle barrel 302 and the rubber ring 13 fixedly installed at the bottom end of the cartridge case 10, during the clamping process, the rubber ring 13 is clamped into the annular groove of the inner groove plate 304. At the same time, by using the contact between the annular groove and the rubber ring 13, the tortuosity of the fitting position is increased. During the process of connecting the opening of the container, by applying pressure with the air cylinder 6, the fitting pressure between the rubber ring 13 and the inner groove plate 304 is increased, improving the airtightness. And the bottom end of the rubber cylinder 11 is clamped with a slip ring 12 through the clamping groove. A joint 9 is fixedly installed on the inner wall of the slip ring 12. The top end of the joint 9 is connected to an air pump 7 through a pipeline.

[0043] The inner wall of the rubber cylinder 11 is closely attached to the outer side of the joint 9, and the outer side of the rubber cylinder 11 is closely attached to the inner wall of the cartridge case 10. The outer side of the slip ring 12 is slidably adapted to the inner wall of the cartridge case 10, and an inner groove annular groove is opened at the bottom of the slip ring 12. When the air pump 7 is started, air enters the joint 9 through the pipeline, and then through the cooperation of the cartridge case 10 and the sealing mechanism 3, the air is introduced into the container. When the internal air pressure gradually increases, the air pressure passes through the joint 9, causing the joint 9 to have a tendency to pop out. At this time, the slip ring 12 presses the rubber cylinder 11 under this tendency, causing the rubber cylinder 11 to have a tendency to deform, increasing the contact pressure with the joint 9 and the cartridge case 10, restricting the joint 9 from popping out, and at the same time increasing the fitting pressure. The cover cylinder 301 is a conical cover with the inner diameter and outer diameter gradually decreasing from top to bottom, and a chute is opened on the outer side of the cover cylinder 301. A sliding cover 303 is slidably installed at the chute of the cover cylinder 301. A gasket ring 305 is clamped between the bottom end of the cover cylinder 301 and the sliding cover 303. A bottom sliding cylinder 306 is fixedly installed at the bottom end of the sliding cover 303. The bottom end of the bottom sliding cylinder 306 inclines inward, and an arc-shaped pad 307 is fixedly installed at the bottom end of the bottom sliding cylinder 306.

[0044] Second embodiment, on the basis of the first embodiment, please refer to Figures 7 to 8As shown, both the arc-shaped pad 307 and the pad ring 305 are made of rubber material. When the sealing mechanism 3 is driven by the cylinder 6 to move downward, it first contacts the container through the arc-shaped pad 307. At the same time, during the contact process, the bottom sliding cylinder 306 drives the sliding cover 303 to compress the pad ring 305 through the contact pressure, causing the pad ring 305 to deform. The sliding cover 303 slides in the chute of the cover cylinder 301. During the sliding process, the position of the container is adjusted in cooperation with the fixing mechanism 2. The top of the outer side of the cover cylinder 301 is fixedly connected to the air pressure sensor 8. The detection end of the air pressure sensor 8 penetrates the cover cylinder 301 and extends to the inside. The bottom of the inner wall of the cover cylinder 301 is provided with an annular protrusion, and a hollow cylinder 309 is slidably installed on the inner wall of the annular protrusion. The top of the outer side of the hollow cylinder 309 is fixedly installed with an outer pad ring 308, and the bottom end of the hollow cylinder 309 is fixedly installed with a conical mask 310. When the sliding cover 303 slides, the conical mask 310 contacts the opening position of the container. Through the change in the inner diameter of the conical mask 310, during the contact process, the opening position of the container is wrapped. At the same time, under the contact pressure, the outer pad ring 308 is driven by the hollow cylinder 309, increasing the contact pressure between the outer pad ring 308 and the cover cylinder 301. The inner diameter of the conical mask 310 gradually increases from top to bottom. The outer pad ring 308 is made of rubber material, and the outer side of the outer pad ring 308 is closely attached to the inner wall of the cover cylinder 301.

[0045] The third embodiment is based on the first and second embodiments. Please refer to Figures 9 to 10 As shown, the top of the fixing ring 201 is evenly provided with rotating grooves, and rotating blocks 202 are rotatably installed at the rotating groove positions of the fixing ring 201. The top ends of the rotating blocks 202 are fixedly installed with fixing plates 205. One end of the fixing plate 205 away from the rotating block 202 is fixedly installed with a clamping groove plate 209. The outer side of the clamping groove plate 209 is fixedly installed with an inner cushion block 210. The bottoms of the opposite sides of the rotating blocks 202 are fixedly installed with inner convex blocks 212. During the downward movement of the pressing ring 203, through the contact with the inner convex blocks 212, the inner convex blocks 212 move along with the downward movement of the pressing ring 203, driving the top ends of the rotating blocks 202 to move inward. During the movement process, driven by the fixing plate 205 and the clamping groove plate 209, the inner cushion block 210 contacts the container to adjust the position of the container, making the opening position of the container correspond to the sealing mechanism 3. One end of the inner convex block 212 away from the rotating block 202 contacts the bottom of the pressing ring 203. The bottom pad ring 211 is made of elastic material. One end of the fixing plate 205 away from the rotating block 202 is inclined inward. The side of the clamping groove plate 209 away from the fixing plate 205 is an inclined surface that inclines inward from top to bottom. The outer side of the inner cushion block 210 is an arc surface with a central position bulge.

[0046] During use, the worker places the container to be fault-detected into the device and pre-fixes it through the fixing mechanism 2. Subsequently, the appropriate sealing mechanism 3 is selected according to the caliber of the container opening, and the sealing mechanism 3 is clamped with the cartridge 10. Then, the cylinder 6 is started, so that the cylinder 6 drives the sealing mechanism 3 to approach the opening position of the container through the connecting plate 4 and the cartridge 10, and the sealing mechanism 3 is clamped with the opening position of the container. Subsequently, the air pump 7 is started, so that the air pump 7 injects air into the container through the pipeline, and the internal air pressure is detected by the air pressure sensor 8. The air pressure sensor 8 transmits the electrical signal to the display 5 for display, and the airtightness of the container is detected according to the displayed data.

[0047] When the container is placed into the fixing mechanism 2, the worker places the opening of the container upward, so that the bottom of the container is contacted by the spherical block 208 at the top of the support rod 207, and the spherical block 208 supports the container under the restriction of the support rod 207. During the downward movement of the cylinder 6, after the sealing mechanism 3 contacts the container, due to the pressure of the cylinder 6, the tray 204 compresses the bottom gasket ring 211 through the pressure ring 203 to deform, so that the tray 204 and the pressure ring 203 move downward. During the downward movement of the pressure ring 203, through the contact with the inner convex block 212, the inner convex block 212 moves with the downward movement of the pressure ring 203, driving the top end of the rotating block 202 to move inward. During the movement, through the drive of the fixed plate 205 and the slot plate 209, the inner cushion block 210 contacts the container to adjust the position of the container, so that the opening position of the container corresponds to the sealing mechanism 3.

[0048] When the cartridge 10 is clamped with the sealing mechanism 3, the clamping block on the outer side of the cartridge 10 cooperates with the buckle on the inner wall of the buckle barrel 302, so that the cartridge 10 and the buckle barrel 302 are clamped. At the same time, during the clamping process, the inner groove plate 304 on the inner wall of the buckle barrel 302 cooperates with the rubber ring 13 fixedly installed at the bottom end of the cartridge 10. During the clamping process, the rubber ring 13 is clamped into the ring groove of the inner groove plate 304. At the same time, by using the contact between the ring groove and the rubber ring 13, the tortuosity of the fitting position is increased. During the process of connecting the container opening, by using the pressure of the cylinder 6, the fitting pressure between the rubber ring 13 and the inner groove plate 304 is increased to improve the airtight seal. At the same time, when the air pump 7 is started, the air enters the joint 9 through the pipeline, and then through the cooperation of the cartridge 10 and the sealing mechanism 3, the air is introduced into the container. When the internal air pressure gradually increases, the air pressure passes through the joint 9, causing the joint 9 to have a tendency to pop out. At this time, the sliding ring 12 presses the rubber cylinder 11 under this tendency, causing the rubber cylinder 11 to have a tendency to deform, increasing the contact pressure with the joint 9 and the cartridge 10, restricting the joint 9 from popping out, and at the same time increasing the fitting pressure.

[0049] In the sealing mechanism 3, when the sealing mechanism 3 is driven by the cylinder 6 to move downward, it first contacts the container through the arc-shaped pad 307. At the same time, during the contact process, the bottom sliding cylinder 306 drives the sliding cover 303 to compress the gasket ring 305 through the contact pressure, causing the gasket ring 305 to deform. The sliding cover 303 slides in the chute of the cover cylinder 301. During the sliding process, the fixing mechanism 2 is coordinated to adjust the position of the container. At the same time, when the sliding cover 303 slides, the conical face cover 310 contacts the opening position of the container. Through the change in the inner diameter of the conical face cover 310, during the contact process, the opening position of the container is wrapped. At the same time, under the contact pressure, the hollow cylinder 309 drives the outer gasket ring 308, increasing the contact pressure between the outer gasket ring 308 and the cover cylinder 301.
