Description

Technical Field

[0001] The invention relates to the technical field of pressure vessels, and in particular to a pressure vessel leakage detection device with high reliability. Background Art

[0002] Pressure vessels refer to closed equipment that contains gas or liquid and bears a certain pressure. In order to more effectively implement scientific management and safety supervision and inspection, my country's "Safety Supervision Regulations for Pressure Vessels" divides pressure vessels into three categories based on working pressure, medium hazard and its role in production.

[0003] In actual use, traditional pressure vessel leakage detection often involves completely immersing the gas-filled pressure vessel in water to see if there are bubbles on the surface of the pressure vessel. If the pressure vessel to be tested is repeatedly lifted into a container filled with water by hand, and the pressure vessel needs to be taken out of the water after the test is completed, the pressure vessel has a certain weight, which makes this operation more laborious.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1

[0028] See also Figure 1-Figure 4 The present invention provides a technical solution: a pressure vessel leakage detection device with high reliability, comprising a base 1, and a glass container 2 for holding water located above the base 1, a carrying plate 31 and a placement table 32 for carrying the pressure vessel to be detected are arranged above the base 1, the carrying plate 31 and the placement table 32 are intermittently fitted together, and a conveying component 4 for driving the carrying plate 31 to move into the glass container 2 is arranged above the base 1.

[0029] In use, in the initial state, the carrying plate 31 and the placing table 32 are at the same horizontal position and fit each other, all the pressure vessels to be tested are placed on the placing table 32, one of the pressure vessels to be tested is manually moved onto the carrying plate 31, and an appropriate amount of external water source is injected into the glass container 2;

[0030] The conveying component 4 drives the carrying plate 31 and the pressure container on the carrying plate 31 to move into the glass container 2, and inspects the pressure container to see whether bubbles are generated on the surface of the pressure container. After the pressure container inspection is completed, the carrying plate 31 and the pressure container on the carrying plate 31 can be driven to move outside the glass container 2 to return to their original positions, thereby effectively improving the convenience of the device.

[0031] A fixing plate 33 is arranged above the bearing plate 31 , a spring 34 is fixedly connected between the fixing plate 33 and the bearing plate 31 , a limited telescopic rod is arranged inside the spring 34 , one end of the limited telescopic rod is fixed to the bearing plate 31 , and the other end is fixed to the fixing plate 33 .

[0032] During use, the staff first pulls the fixing plate 33 upwards, and moves one of the pressure vessels to be inspected on the placement table 32 to the supporting plate 31 , so that the pressure vessel is clamped between the fixing plate 33 and the supporting plate 31 .

[0033] The conveying assembly 4 includes a vertical plate 41 located above the base 1, an L-shaped connecting rod 13 is fixedly connected between the vertical plate 41 and the base 1, a slide plate 42 is slidably connected to the left and right limited positions on the surface of the vertical plate 41, a U-shaped slide groove 43 is opened on the surface of the vertical plate 41, and a V-shaped slide groove 44 is opened on the surface of the slide plate 42, an L-shaped slide rod 45 is slidably connected in the V-shaped slide groove 44, one end of the L-shaped slide rod 45 is rectangular and is slidably connected in the U-shaped slide groove 43 after passing through the V-shaped slide groove 44, the carrying plate 31 is fixedly connected to the lower end of the L-shaped slide rod 45, the glass container 2 is located directly below one end of the U-shaped slide groove 43, and an L-shaped long rod 11 is fixedly connected between the glass container 2 and the base 1.

[0034] During use, in the initial state, the supporting plate 31 and the placing table 32 are in the same horizontal position, the slide plate 42 is in a state of being away from the glass container 2, and the L-shaped slide bar 45 is located at one end of the U-shaped slide groove 43. When the staff places one of the pressure vessels to be inspected on the placing table 32 on the supporting plate 31, the slide plate 42 is driven to move horizontally toward the side of the glass container 2. Since one end of the L-shaped slide bar 45 is slidably connected to the U-shaped slide groove 43 and the V-shaped slide groove 44, when the slide plate 42 moves horizontally toward the side of the glass container 2, it can drive the L-shaped slide bar 45 to move from one end of the U-shaped slide groove 43 to the other end. The L-shaped slide bar 45 can drive the supporting plate 31 fixed at its lower end, and the pressure container to be inspected on the supporting plate 31 to move into the glass container 2 for subsequent inspection work.

[0035] During use, when the pressure vessel in the glass container 2 is inspected, the driving slide 42 moves back in the horizontal direction, so that the slide 42 drives the L-shaped slide bar 45 to move back along the U-shaped slide groove 43 to return to its original position, and the L-shaped slide bar 45 drives the supporting plate 31 fixed at its lower end and the pressure vessel on the supporting plate 31 that has been inspected to return to their original position, and the staff then takes the inspected pressure vessel out of the supporting plate 31.

[0036] A non-complete gear 46 driven by an external driving device and a complete gear 47 intermittently meshing with the non-complete gear 46 are rotatably connected above the base 1. Two L-shaped support rods 12 are vertically fixed to the upper surface of the base 1. The complete gear 47 and the non-complete gear 46 are rotatably connected to the two L-shaped support rods 12 respectively. A rocker arm 48 coaxially fixed with the complete gear 47 is arranged above the base 1. A U-shaped frame 49 is slidably connected to the left and right limited position of the upper surface of the base 1. One end of the rocker arm 48 is fixedly connected to a column 491. The column 491 is slidably connected to the U-shaped frame 49. A connecting rod 492 is fixed between the U-shaped frame 49 and the slide plate 42.

[0037] The external driving device is a motor.

[0038] During use, the motor of the external driving device is started to drive the non-complete gear 46 to rotate. Each rotation of the non-complete gear 46 can drive the complete gear 47 intermittently meshed with it to rotate half a circle. The complete gear 47 can drive the swing rod 48 coaxially fixed with it to rotate while rotating. The swing rod 48 can drive the column 491 vertically fixed at one end to rotate. Since the column 491 is slidably connected to the U-shaped frame 49, and the U-shaped frame 49 can only slide left and right along the base 1, the column 491 can drive the U-shaped frame 49 to reciprocate in the horizontal direction. The U-shaped frame 49 can drive the slide plate 42 to reciprocate in the horizontal direction through the connecting rod 492. Each rotation of the complete gear 47 causes the slide plate 42 to move back and forth once.

[0039] Since the incomplete gear 46 can drive the complete gear 47 intermittently meshing with it to rotate half a circle every time it rotates one circle, the complete gear 47 will stop for a while every time it rotates half a circle, and then the slide plate 42 will move back and forth intermittently. When the slide plate 42 moves from one side of the vertical plate 41 to the other side, it drives the supporting plate 31 and the pressure vessel to be inspected to be immersed in the water of the glass container 2, and then stops for a period of time to reserve a certain amount of inspection time; when the inspection work is completed, the slide plate 42 will move back and forth to its original position, driving the supporting plate 31 and the inspected pressure vessel to return to their original positions, and also stay for a period of time to facilitate the staff to replace the next pressure vessel to be inspected.

[0040] Embodiment 2

[0041] See also Figure 5-Figure 7 This embodiment further illustrates the first embodiment. A driving component 5 for driving the pressure container to rotate is provided in the glass container 2.

[0042] During use, by setting up the driving assembly 5, the pressure container is driven to rotate after entering the glass container 2. The staff can stand on one side to check whether there are bubbles generated on the surface of the pressure container. The staff does not need to check around the glass container 2, which effectively improves the convenience of the device during use.

[0043] The driving assembly 5 includes an inner gear ring 51 rotatably connected to the bottom surface of the inner wall of the glass container 2, and a complete gear 2 52 coaxially fixed with the inner gear ring 51 is arranged above the base 1, and the complete gear 2 52 is intermittently meshed with the non-complete gear 46. Circular holes are opened on the supporting plate 31 and the fixing plate 33, and a circular plate 53 is rotatably connected in the circular hole. A complete gear 3 54 coaxially fixed with one of the circular plates 53 is arranged on the lower surface of the supporting plate 31, and the complete gear 3 54 is intermittently meshed with the inner gear ring 51.

[0044] During use, the staff moves the pressure vessel to be tested from the placement table 32 to the carrying plate 31, and makes the pressure vessel to be tested completely on the circular plate 53. When the carrying plate 31, the circular plate 53 and the pressure vessel to be tested are completely immersed in the water of the glass container 2, the complete gear 3 54 under the carrying plate 31 will mesh with the inner gear ring 51 in the glass container 2.

[0045] At the same time, the incomplete gear 46 will be separated from the complete gear 1 47 during the rotation, so that the carrier plate 31 and the pressure container are in a stationary state in the glass container 2;

[0046] Then the incomplete gear 46 will mesh with the complete gear 2 52, driving the complete gear 2 52 to rotate accordingly. Each rotation of the incomplete gear 46 can drive the complete gear 2 52 to rotate accordingly. The complete gear 2 52 can drive the inner gear ring 51 coaxially fixed thereto to rotate accordingly. The inner gear ring 51 can drive the complete gear 3 54 meshing therewith to rotate accordingly. The complete gear 3 54 can drive the circular plate 53 coaxially fixed thereto to rotate accordingly. The circular plate 53 can drive the pressure vessel located on its upper surface to rotate accordingly, so that the staff can stand on one side of the glass container 2 to observe whether the pressure vessel in the glass container 2 has any leakage problem.

[0047] Embodiment 3

[0048] See also Figure 5-Figure 7 This embodiment further explains the first embodiment. An annular frame 6 and a cleaning assembly 7 for driving the annular frame 6 to reciprocate along the vertical direction are provided on the carrier plate 31. An annular sponge 61 is fixedly connected to the inner wall of the annular frame 6.

[0049] During use, when an object is immersed in water, some small bubbles will be attached to its surface. When the pressure container is immersed in the water in the glass container 2, some small bubbles will also be attached to its surface, which can be easily confused with the bubbles generated when the pressure container leaks, making it difficult for the staff to distinguish whether the pressure container is leaking.

[0050] By setting up the cleaning component 7, the annular frame 6 and the annular sponge 61 are driven to move vertically along the outer wall of the pressure vessel to remove the bubbles attached to the surface of the pressure vessel, so that the staff can more easily distinguish whether the pressure vessel has a leakage problem.

[0051] The cleaning assembly 7 includes a threaded rod 71 rotatably connected to the upper surface of the supporting plate 31, a complete gear 72 coaxially fixed with the threaded rod 71 is arranged below the supporting plate 31, an outer gear 73 is sleeved on the surface of the inner gear ring 51, and the outer gear ring 73 is intermittently meshed with the complete gear 72, the threaded rod 71 passes through the annular frame 6 and is threadedly connected to the annular frame 6, a limiting rod 74 is vertically fixed to the upper surface of the supporting plate 31, and the annular frame 6 is slidably connected to the limiting rod 74 in an upper and lower limit position.

[0052] During use, after the pressure vessel is placed on the circular plate 53, the annular frame 6 and the annular sponge 61 are sleeved on the surface of the pressure vessel, and the annular sponge 61 is close to the outer wall of the pressure vessel. When the complete gear three 54 and the inner gear ring 51 are meshed with each other, the outer gear ring 73 and the complete gear four 72 are also meshed with each other. When the inner gear ring 51 rotates, it can drive the outer gear ring 73 sleeved on its surface to rotate accordingly. The outer gear ring 73 can drive the complete gear four 72 meshed with it to rotate accordingly. The complete gear four 72 can drive the threaded rod 71 coaxially fixed thereto to rotate accordingly. The threaded rod 71 can drive the annular frame 6 threadedly connected to its surface to move in the vertical direction. The annular frame 6 can drive the annular sponge 61 fixedly connected to its inner wall to move in the vertical direction to remove the bubbles on the surface of the pressure vessel.

[0053] Working principle: This is a highly reliable pressure vessel leakage detection device. When in use, in the initial state, the carrying plate 31 and the placement table 32 are at the same horizontal position and fit each other. All the pressure vessels to be detected are placed on the placement table 32. One of the pressure vessels to be detected is manually moved onto the carrying plate 31. The slide plate 42 is in a state away from the glass container 2. The L-shaped slide bar 45 is located at one end of the U-shaped slide groove 43. A proper amount of external water source is injected into the glass container 2.

[0054] Start the motor of the external driving device to drive the non-complete gear 46 to rotate. Every time the non-complete gear 46 rotates one circle, it can drive the complete gear 47 intermittently meshed with it to rotate half a circle. While rotating, the complete gear 47 can drive the swing rod 48 coaxially fixed with it to rotate. The swing rod 48 can drive the column 491 vertically fixed at one end to rotate. Since the column 491 is slidably connected to the U-shaped frame 49, and the U-shaped frame 49 can only slide left and right along the base 1, the column 491 can drive the U-shaped frame 49 to reciprocate in the horizontal direction. The U-shaped frame 49 can drive the slide plate 42 to reciprocate in the horizontal direction through the connecting rod 492. Every time the complete gear 47 rotates one circle, the slide plate 42 moves back and forth once.

[0055] The slide plate 42 moves along the horizontal direction toward the glass container 2. Since one end of the L-shaped slide bar 45 is slidably connected to the U-shaped slide groove 43 and the V-shaped slide groove 44, when the slide plate 42 moves along the horizontal direction toward the glass container 2, it can drive the L-shaped slide bar 45 to move from one end of the U-shaped slide groove 43 to the other end. The L-shaped slide bar 45 can drive the supporting plate 31 fixed at its lower end, and the pressure container to be inspected on the supporting plate 31 to move into the glass container 2 to facilitate subsequent inspection work.

[0056] In use, when the pressure vessel in the glass container 2 is inspected, the driving slide 42 moves back in the horizontal direction, so that the slide 42 drives the L-shaped slide bar 45 to move back along the U-shaped slide groove 43 to restore to the original position, and the L-shaped slide bar 45 drives the supporting plate 31 fixed at the lower end thereof and the pressure vessel on the supporting plate 31 to return to the original position, and the staff then takes the inspected pressure vessel out of the supporting plate 31;

[0057] Since the incomplete gear 46 can drive the complete gear 1 47 intermittently meshed with it to rotate half a circle every time it rotates one circle, the complete gear 1 47 will stop for a while every time it rotates half a circle, and then the slide plate 42 will intermittently reciprocate. When the slide plate 42 moves from one side of the vertical plate 41 to the other side, it drives the carrying plate 31 and the pressure vessel to be tested to be immersed in the water of the glass container 2, and then stops for a period of time to reserve a certain amount of testing time; when the testing work is completed, the slide plate 42 will move back to its original position, driving the carrying plate 31 and the pressure vessel that has been tested to return to their original positions, and also stay for a period of time to facilitate the staff to replace the next pressure vessel to be tested;

[0058] The staff moves the pressure vessel to be tested from the placement table 32 to the carrying plate 31, and makes the pressure vessel to be tested completely on the circular plate 53. When the carrying plate 31, the circular plate 53 and the pressure vessel to be tested are completely immersed in the water of the glass container 2, the complete gear 3 54 under the carrying plate 31 will mesh with the inner gear ring 51 in the glass container 2.

[0059] At the same time, the incomplete gear 46 will be separated from the complete gear 1 47 during the rotation, so that the carrier plate 31 and the pressure container are in a stationary state in the glass container 2;

[0060] Then the incomplete gear 46 will mesh with the complete gear 2 52, driving the complete gear 2 52 to rotate accordingly. Each rotation of the incomplete gear 46 can drive the complete gear 2 52 to rotate accordingly. The complete gear 2 52 can drive the inner gear ring 51 coaxially fixed thereto to rotate accordingly. The inner gear ring 51 can drive the complete gear 3 54 meshing therewith to rotate accordingly. The complete gear 3 54 can drive the circular plate 53 coaxially fixed thereto to rotate accordingly. The circular plate 53 can drive the pressure container located on its upper surface to rotate accordingly, so that the staff standing on one side of the glass container 2 can observe whether the pressure container in the glass container 2 has leakage problems.

[0061] After placing the pressure vessel on the circular plate 53, the annular frame 6 and the annular sponge 61 are sleeved on the surface of the pressure vessel, and the annular sponge 61 is close to the outer wall of the pressure vessel. When the complete gear three 54 and the inner gear ring 51 are meshed with each other, the outer gear ring 73 and the complete gear four 72 are also meshed with each other. When the inner gear ring 51 rotates, it can drive the outer gear ring 73 sleeved on its surface to rotate accordingly. The outer gear ring 73 can drive the complete gear four 72 meshed with it to rotate accordingly. The complete gear four 72 can drive the threaded rod 71 coaxially fixed thereto to rotate accordingly. The threaded rod 71 can drive the annular frame 6 threadedly connected to its surface to move in the vertical direction. The annular frame 6 can drive the annular sponge 61 fixedly connected to its inner wall to move in the vertical direction to remove the bubbles on the surface of the pressure vessel.
