Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, and in particular to an airtightness testing device for oil drums. Background Technology

[0002] In many industries such as petrochemicals, food processing, and pharmaceuticals, oil drums serve as crucial storage and transportation containers for liquids and gases. Their airtightness plays a vital role in ensuring transportation safety, preventing media leakage, and avoiding environmental pollution. Poor airtightness of oil drums can not only lead to leakage of stored substances and economic losses, but also easily cause serious safety accidents such as fires and explosions, while also causing incalculable damage to the ecological environment.

[0003] A typical oil drum airtightness testing device consists of a support frame, a locking structure, and a sealing cap. The support frame supports the oil drum through the support structure to ensure that the oil drum is in a fixed position. The locking structure uses mechanical linkage to tightly connect the sealing cap to the oil drum opening. The sealing cap and the locking structure work together to form a closed cavity. When gas is injected into the cavity or pressure is applied, the airtightness of the oil drum can be judged by detecting pressure changes or gas leakage.

[0004] In existing technologies, most oil drum airtightness testing devices determine the airtightness of the oil drum by filling it with gas at a certain pressure and then detecting gas leakage. However, existing testing devices cannot accurately align with the oil drum when sealing the top, leading to gas leakage during the testing process. This leakage not only causes the actual pressure inside the oil drum to differ from the set pressure, interfering with the detection system's acquisition and analysis of pressure change data, but also results in biased test results that fail to accurately reflect the oil drum's airtightness. Consequently, oil drums with airtightness issues can enter the market, posing a risk of oil leakage, environmental pollution, and even safety accidents. Therefore, this paper proposes an oil drum airtightness testing device to address these problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an oil drum airtightness testing device, which aims to improve the problem in the prior art where the top of the test drum cannot be accurately aligned with the testing device, resulting in poor sealing and gas leakage, which in turn affects the accuracy of the airtightness test results.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An oil drum airtightness testing device includes a support plate. An installation mechanism is located on the top right side of the support plate, and a calibration mechanism is located on the top left side of the support plate. The installation mechanism includes two lifting rails, the bottoms of which are fixedly connected to the top right side of the support plate. A top block is threadedly connected to the top of each lifting rail. A slider is slidably connected to the outside of each lifting rail. A slide rail is threadedly connected to the outside of each slider. A control block is slidably connected to the outside of each slide rail. A telescopic rod is fixedly connected inside the control block. A rotating shaft is rotatably connected to the other end of the telescopic rod. A lower pressure plate is fixedly connected to the bottom of the rotating shaft. A detection component is fixedly connected inside the lower pressure plate. A drive component is fixedly connected to the outside of the support plate. As a further description of the above technical solution: The calibration mechanism includes two movable rails. The bottom of the two movable rails is fixedly connected to the top left side of the support plate. A limiting block is fixedly connected to the top of each movable rail. A moving block is slidably connected to the outside of each movable rail. An extension rod is rotatably connected to the outside of each moving block. An arc plate is rotatably connected to the other end of each extension rod. As a further description of the above technical solution: The top of the support plate is fixedly connected to a slot, the inside of which a test bucket is engaged, and the outside of the support plate is fixedly connected to a mounting plate. As a further description of the above technical solution: The detection assembly includes a docking shaft, which is externally fixedly connected to the top inner side of the lower pressure plate. An air inlet is installed inside the docking shaft, and a sealing port is slidably connected inside the lower pressure plate. As a further description of the above technical solution: The drive assembly includes a fixed plate, which is fixedly connected to the outside of the support plate. A hydraulic push rod is fixedly connected to the top of the fixed plate, and the output end of the hydraulic push rod is fixedly connected to the bottom of the control block. As a further description of the above technical solution: The hydraulic push rod is externally fixedly connected to a locking block, and the outer two sides of the locking block are engaged with the adjacent side of the arc plate. As a further description of the above technical solution: The top of the test barrel is snapped into the bottom of the lower pressure plate, the output end of the inflation port is fixedly connected to the top of the test barrel, and the bottom of the sealing port is threadedly connected to the top of the test barrel. As a further description of the above technical solution: The hydraulic push rod generates power to push the control block, causing the sliders on both sides of the slide rail to slide outside the lifting rail, so that the bottom of the lower pressure plate is supported on the top of the test barrel.

[0007] This utility model has the following beneficial effects: 1. In this utility model, a hydraulic push rod drives the control block to slide on the slide rail, causing the slider to move on the lifting rail. This achieves the effect of moving the lower pressure plate closer to the top of the test bucket and adjusting its position. A telescopic rod is fixed inside the control block, driving the rotating shaft to rotate at one end of the telescopic rod. This allows the lower pressure plate to adaptively adjust its position and angle according to the top of the test bucket, thereby achieving precise docking and tight fit between the lower pressure plate and the top of the test bucket. This ensures a reliable seal between the sealing port and the top of the test bucket, preventing gas leakage during inflation testing and ensuring accurate and reliable airtightness test results.

[0008] 2. In this utility model, the movable rail provides a moving track for the moving block, enabling the moving block to slide stably. With the cooperation of the moving block, the extension rod, and the arc plate, the arc plate can be precisely adjusted in position and angle. With the locking cooperation between the arc plate and the locking block, the position of the test bucket is calibrated and constrained, thereby solving the problems of inaccurate position calibration, unstable constraint, and inaccurate position and angle adjustment of the test bucket during the detection or operation process.

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.

[0012] Reference Figure 1 , Figure 2 and Figure 4 The present invention provides an embodiment of an oil drum air tightness testing device, which includes a support plate 1. The support plate 1 serves as the basic load-bearing component of the entire oil drum air tightness testing device and provides an installation and support platform. An installation mechanism 5 is provided on the top right side of the support plate 1, and a calibration mechanism 8 is provided on the top left side of the support plate 1. The mounting mechanism 5 includes two lifting rails 51, which provide vertical movement tracks for the sliders 53. The bottoms of the two lifting rails 51 are fixedly connected to the top right side of the support plate 1. Each lifting rail 51 has a top block 52 threadedly connected to its top, which limits the range of motion of the lifting rail 51. Slider blocks 53 are slidably connected to the outside of each lifting rail 51. The sliders 53 slide on the lifting rails 51, driving the slide rail 54 and control block 55 to move vertically. The slide rail 54 is threadedly connected to the outside of the slider 53, providing a horizontal sliding track for the control block 55. The control block 55 is slidably connected to the outside of the slide rail 54, connecting the hydraulic push rod 72 and the telescopic rod 56 to control the hydraulic... The thrust of push rod 72 is transmitted to the lower pressure plate 58. A telescopic rod 56 is fixedly connected inside the control block 55. The telescopic rod 56 plays a buffering and adjustment role between the control block 55 and the lower pressure plate 58. It can adaptively adjust the position of the lower pressure plate 58 according to the actual situation of the top of the test barrel 3. The other end of the telescopic rod 56 is rotatably connected to the rotating shaft 57. The rotating shaft 57 connects the telescopic rod 56 and the lower pressure plate 58, so that the lower pressure plate 58 can rotate around its axis. The bottom of the rotating shaft 57 is fixedly connected to the lower pressure plate 58. The lower pressure plate 58 serves as the mounting carrier of the detection component 6 and is in direct contact with the top of the test barrel 3. The detection component 6 is fixedly connected inside the lower pressure plate 58, and the drive component 7 is fixedly connected to the outside of the support plate 1. The testing component 6 includes a docking shaft 61, which serves as the mounting base for the inflation port 62, providing support and positioning. The docking shaft 61 is externally fixedly connected to the top inner side of the lower pressure plate 58. The inflation port 62 is installed inside the docking shaft 61. During the airtightness test, the inflation port 62 serves as a channel for injecting gas into the test barrel 3. The lower pressure plate 58 has a sliding connection to a sealing port 63. During the test, the sealing port 63 is threadedly connected to the top of the test barrel 3 to achieve a seal between the lower pressure plate 58 and the top of the test barrel 3, preventing gas leakage during inflation and ensuring the accuracy of the test results. The drive assembly 7 includes a fixing plate 71, which provides a stable mounting and fixing point for the hydraulic push rod 72. The fixing plate 71 is externally fixedly connected to the outside of the support plate 1. The top of the fixing plate 71 is fixedly connected to the hydraulic push rod 72. The hydraulic push rod 72 serves as the power source for the mounting mechanism 5 and pushes the control block 55 by outputting thrust. The output end of the hydraulic push rod 72 is fixedly connected to the bottom of the control block 55. The top of the support plate 1 is fixedly connected to a slot 2, which is used to accurately position and fix the test barrel 3. The test barrel 3 is locked inside the slot 2. The test barrel 3 is the object of this device and is used to hold oil. Its airtightness is directly related to the safety of oil storage and transportation. This device detects whether there is any air leakage. The support plate 1 is fixedly connected to an mounting plate 4. The mounting plate 4 assists the support plate 1, provides additional installation and fixing points for other components, enhances the overall structural stability of the device, and shares some of the force during the working process. The hydraulic push rod 72 generates power to push the control block 55, which drives the sliders 53 on both sides of the slide rail 54 to slide outside the lifting rail 51, so that the bottom of the lower pressure plate 58 is supported on the top of the test barrel 3.

[0013] Reference Figures 1 to 3The calibration mechanism 8 includes two movable rails 81, which provide a track for the moving block 83. The bottom of the two movable rails 81 is fixedly connected to the top left side of the support plate 1. A limiting block 82 is fixedly connected to the top of each movable rail 81, restricting the range of movement of the moving block 83 on the movable rail 81. The moving block 83 is slidably connected to the outside of each movable rail 81. The moving block 83 slides on the movable rail 81, driving the extension rod 84 and the arc plate 85 to move. The extension rod 84 is rotatably connected to the outside of each moving block 83. The extension rod 84 serves as a transmission connection component between the moving block 83 and the arc plate 85, converting the horizontal movement of the moving block 83 on the movable rail 81 into adjustment of the position and angle of the arc plate 85. The other end of the extension rod 84 is rotatably connected to an arc plate 85. The arc plate 85 cooperates with the locking block 86 on the outside of the hydraulic push rod 72. By adjusting its shape and position, the position of the hydraulic push rod 72 is calibrated and constrained. The locking block 86 is fixedly connected to the outside of the hydraulic push rod 72. The locking block 86 serves as a connection and calibration component between the hydraulic push rod 72 and the calibration mechanism 8. It is fixed to the outside of the hydraulic push rod 72 and cooperates with the arc plate 85 to receive the force and position adjustment applied by the arc plate 85. The two sides of the outer side of the locking block 86 are locked onto the adjacent side of the arc plate 85. The top of the test barrel 3 is locked onto the bottom of the lower pressure plate 58. The output end of the air inlet 62 is fixedly connected to the top of the test barrel 3. The bottom of the sealing port 63 is threadedly connected to the top of the test barrel 3.

[0014] Working principle: During operation, the test barrel 3 is first inserted into the slot 2 at the top of the support plate 1 for fixation. The mounting plate 4 assists the support plate 1 to enhance structural stability. The hydraulic push rod 72 in the drive assembly 7 is fixed to the fixing plate 71, and its output end is connected to the control block 55. After the hydraulic push rod 72 is started, it pushes the control block 55 to slide horizontally on the slide rail 54, while driving the slider 53 to move vertically on the lifting rail 51, so that the lower pressure plate 58 moves closer to the top of the test barrel 3. The telescopic rod 56 and the rotating shaft 57 work together to adjust the position and angle of the lower pressure plate 58 according to the top of the test barrel 3 until the bottom of the lower pressure plate 58 is in contact with the top of the test barrel 3. At this time, the sealing port 63 is threadedly connected to the top of the test barrel 3 to achieve a seal, and the air inlet 62 is connected to the inside of the test barrel 3.

[0015] In the calibration mechanism 8, the movable rail 81 provides a moving track for the movable block 83, and the limiting block 82 restricts its movement range. When the movable block 83 slides, it drives the extension rod 84. The extension rod 84 converts the horizontal movement of the movable block 83 into the adjustment of the position and angle of the arc plate 85. The arc plate 85 is engaged with the locking block 86 outside the hydraulic push rod 72 to calibrate and constrain the position of the test barrel 3, ensuring that the installation mechanism 5 can accurately drive the lower pressure plate 58 to dock with the test barrel 3, and ensuring that the air inlet 62 can smoothly inflate the test barrel 3 to complete the air tightness test.

[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
