Description

Technical Field

[0001] The invention relates to the technical field of sealing ring leakage prevention simulation test equipment, in particular to a sealing component leakage prevention simulation device under an alkaline electrolysis environment and a simulation method thereof. Background Art

[0002] In mechanical equipment, sealing rings are often required to prevent leakage of liquids, gases and other media. In order to ensure the normal operation and safety of the equipment, it is usually necessary to conduct a leakage simulation test on the sealing ring. Through simulation tests, potential leakage problems can be discovered and solved in advance, avoiding equipment failures, environmental pollution and even safety accidents caused by leakage in actual use.

[0003] At present, the simulation devices for sealing ring leakage prevention include pressure resistance test, compression test, dynamic sealing test, air tightness test, etc. Among them, the air tightness test method needs to use an air tightness detector for leakage prevention simulation test. The air tightness detector is an instrument that simulates water pressure by air pressure to detect the waterproof and leak-proof of the product. After entering the detection link, the pressure sensor records the current pressure value in real time. After testing for a period of time, according to the product standard test time, the real-time pressure value inside the product or the inner cavity of the contour mold is recorded. By comparing the pressure difference between the two pressure values, it can be determined whether the sealing ring has a leak.

[0004] However, when using sensors for detection, the sensor's measurement value is affected by environmental factors such as temperature, humidity, and air pressure, resulting in large measurement errors. In addition, electromagnetic interference can also affect the operation of the sensor, resulting in inaccurate data. Summary of the invention

[0005] The object of the present invention is to provide a sealing leak-proof simulation device and a simulation method thereof in an alkaline electrolytic environment to solve the problems raised in the above-mentioned background technology.

[0007] The sealing component leakage prevention simulation device in an alkaline electrolysis environment as described above: the pressure-applying assembly comprises a plug disc sealingly and slidably arranged in the fixed cylinder, and a lifting plate is arranged on a side of the plug disc away from the mounting disc; It also includes a turntable rotatably mounted on the housing, wherein a protruding column is arranged on a side of the turntable facing the lifting plate, and the protruding column is slidably arranged in a sliding groove provided on the lifting plate.

[0008] The sealing leakage prevention simulation device in the alkaline electrolysis environment as described above: the lifting assembly includes a screw rod rotatably mounted on the housing, and the screw rod is threadedly connected to a threaded sleeve arranged on the mounting plate.

[0009] The sealing anti-leakage simulation device in the alkaline electrolysis environment as described above: the driving part includes a driving rod rotatably installed in the casing, the driving rod is provided with a lifting ring, the lifting ring is provided with a reciprocating plate, and the inner wall of the lifting ring is formed with a protrusion, the protrusion is slidably arranged in an interlocking groove body opened on the outer wall of the driving rod, and the driving rod is connected to the screw rod and the turntable through a first linkage part and a second linkage part respectively.

[0010] The sealing leakage prevention simulation device in the alkaline electrolysis environment as described above: the mosaic groove body includes a first spiral groove opened on the outer wall of the driving rod, the end of the first spiral groove away from the bottom of the casing is connected to a vertical groove, and the end of the vertical groove away from the first spiral groove is connected to a second spiral groove opened on the outer wall of the driving rod.

[0011] As described above, the sealing leakage prevention simulation device in the alkaline electrolysis environment: the first linkage member includes a first driving wheel coaxially fixedly connected to the driving rod, and a first driven wheel coaxially fixedly connected to the screw rod, and the first driving wheel cooperates with the first driven wheel to drive the screw rod to rotate.

[0012] The seal leakage prevention simulation device in the alkaline electrolysis environment as described above: the second linkage member includes a second driving wheel coaxially fixedly connected to the driving rod, and a second driven wheel rotatably installed in the casing, the second driven wheel is connected to the turntable through a bevel gear set, and the second driven wheel cooperates with the second driving wheel to drive the turntable to rotate.

[0013] The sealing leakage prevention simulation device in the alkaline electrolysis environment as described above: the reciprocating structure includes a pulley rotatably installed in the casing, and two groups of pulleys are arranged along the height direction of the casing. A belt is arranged between the two groups of pulleys, and a trigger rod is arranged on the belt. The trigger rod is slidably arranged in a movable groove opened on the reciprocating plate.

[0014] The sealing anti-leakage simulation device in the alkaline electrolysis environment as described above: the sealing detection structure includes a connecting tube connected to the fixed tube, a sealing block is sealed at one end of the connecting tube away from the fixed tube, and a spring is also slidably arranged in the connecting tube, one end of the spring abuts against the sealing block, and the other end is connected to a moving block slidably arranged in the connecting tube.

[0015] A simulation method for a sealing component leakage prevention simulation device in an alkaline electrolysis environment is also proposed, using the sealing component leakage prevention simulation device in an alkaline electrolysis environment as described above, comprising the following steps: Step 1: In the initial state, the mounting plate is separated from the fixing cylinder, and the lifting plate is away from the mounting plate. When in use, the sealing ring is first placed on the mounting plate, and then the motor is started. The reciprocating structure moves, which can drive the driving rod to rotate continuously in the same direction; Step 2: During the rotation of the driving rod, the first linkage is first triggered to drive the screw to rotate, and then drives the mounting plate to move toward the fixed cylinder until the mounting plate is combined with the fixed cylinder to form a closed environment in the fixed cylinder. Then, the first linkage stops and the second linkage is triggered to drive the pressure component to move, thereby causing the lifting plate to descend, thereby compressing the air in the fixed cylinder. At this time, the compressed air will push the moving block to rise; Step 3: Stop the reciprocating structure and observe the position of the moving block after a period of time to know the sealing performance of the sealing ring.

[0016] Compared with the prior art, the present invention has the following beneficial effects: By providing a driving assembly, a lifting assembly and a pressure assembly, the action of the driving assembly can drive the driving rod to rotate counterclockwise first and then clockwise. When the driving rod rotates counterclockwise, the first linkage member drives the lifting assembly to move, which can force the mounting plate to move toward the fixed cylinder, thereby creating a closed environment inside the fixed cylinder for subsequent simulation testing. When the driving rod rotates clockwise, the second linkage member drives the pressure-applying assembly to move, which can force the piston disc to squeeze the air in the fixed cylinder to change the pressure in the fixed cylinder. After the pressure in the fixed cylinder stabilizes, the moving block in the sealing detection structure on the fixed cylinder cooperates with the scale line on the connecting pipe, which can intuitively and clearly reflect the sealing condition of the current sealing ring. At this time, a record is made. After a period of time, the position of the moving block is recorded again using the scale line. By comparing the two recorded values, the leakage condition of the sealing ring can be known. The above-mentioned leakage-proof simulation process of the sealing performance of the sealing ring is completed through the mutual cooperation of the mechanical structure. Compared with the traditional test using a pressure sensor, the movement of the mechanical structure is not easily affected by environmental factors such as temperature, humidity, and air pressure, and the measurement error is relatively small. Therefore, the accuracy of the test result will be relatively high. At the same time, in terms of maintenance, the replacement or maintenance cost of any component in the present invention is relatively low, and the maintenance speed will be relatively fast.

DETAILED DESCRIPTION

[0029] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0030] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0031] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0032] See also Figure 1-Figure 11 In an embodiment of the present invention, a sealing leakage simulation device in an alkaline electrolysis environment includes: A housing 1, wherein a fixing tube 3 is disposed on the housing 1, a sealing detection structure is disposed on the fixing tube 3, and the fixing tube 3 is connected to a pressure-applying component disposed on the housing 1; The housing 1 is also provided with a lifting assembly, which is connected to a mounting plate 2 slidably disposed on the housing 1 and is used to drive the mounting plate 2 to move toward the fixing cylinder 3 so that a closed environment is formed in the fixing cylinder 3 .

[0033] Preferably, see Figure 3 , Figure 4 , Fig.11 In particular, the above-mentioned fixed cylinder 3 is coaxially arranged with the mounting disk 2, and a docking port 301 is formed at the lower end of the fixed cylinder 3. A placement groove 201 is opened on the mounting disk 2, and the placement groove 201 is used to place the sealing ring 12. In the initial state, the mounting disk 2 is separated from the fixed cylinder 3. When in use, the sealing ring 12 is first placed in the placement groove 201, and then the lifting component is driven to move. The lifting component can drive the mounting disk 2 to move toward the fixed cylinder 3. When the mounting disk 2 rises to the highest point, the sealing ring 12 and the docking end surface of the docking port 301 are compacted. At this time, a closed environment is formed in the fixed cylinder 3. At this time, the air in the fixed cylinder 3 is compressed, and the state of the sealing detection structure can be changed. After a period of time, the sealing performance of the sealing ring 12 on the mounting disk 2 can be judged by observing the state of the sealing detection structure.

[0034] The pressure-applying assembly includes a plug disc 1802 sealingly and slidably disposed in the fixed cylinder 3 , and a lifting plate 18 is disposed on a side of the plug disc 1802 away from the mounting disc 2 .

[0035] For details, please refer to Figure 1 , Figure 8 Two groups of connecting rods are arranged on the piston disc 1802, and one end of the connecting rod away from the piston disc 1802 is fixedly connected to the lifting plate 18. Under the connection of the two groups of connecting rods, the lifting plate 18 can only move along the axial direction of the fixed cylinder 3, so that the air in the fixed cylinder 3 can be compressed when the fixed cylinder 3 is in a closed environment.

[0036] It also includes a turntable 17 rotatably mounted on the housing 1 , and a protruding column 1701 is provided on one side of the turntable 17 facing the lifting plate 18 , and the protruding column 1701 is slidably arranged in a sliding groove 1801 provided on the lifting plate 18 .

[0037] The lifting assembly includes a screw rod 11 rotatably mounted on the housing 1 , and the screw rod 11 is threadedly connected to a threaded sleeve 13 disposed on the mounting plate 2 .

[0038] Preferably, see Figure 1 , Figure 2 , Figure 3The housing 1 is symmetrically provided with two groups of guide rods 5 along its width direction, and the mounting plate 2 is slidably arranged on the two groups of guide rods 5. Under the restriction of the two groups of guide rods 5, the mounting plate 2 can only be lifted and lowered along the axial direction of the fixed cylinder 3. When the screw rod 11 is driven to rotate continuously in the same direction, the rotating screw rod 11, with the cooperation of the guide rods 5, can force the threaded sleeve 13 to drive the mounting plate 2 to move toward the fixed cylinder 3, so that the fixed cylinder 3 forms a closed environment. At the same time, due to the self-locking characteristics of the screw rod 11, when the subsequent pressure-applying component compresses the air in the fixed cylinder 3, the mounting plate 2 will not be displaced in the direction away from the fixed cylinder 3, and then the leakage-proof simulation test of the sealing ring 12 can be completed, thereby judging the sealing performance of the sealing ring 12.

[0039] The sealing detection structure includes a connecting tube 4 connected to the fixed tube 3, and a sealing block 6 is sealed at one end of the connecting tube 4 away from the fixed tube 3, and a spring 23 is also slidably arranged in the connecting tube 4, one end of the spring 23 abuts against the sealing block 6, and the other end is connected to a moving block 22 slidably arranged in the connecting tube 4.

[0040] For details, please refer to Figure 8 The connecting tube 4 is made of transparent material, and a scale line 401 is arranged on the outer wall, and the scale line 401 can directly reflect the moving distance of the moving block 22 in the connecting tube 4, and a circle of baffle ring 402 is formed on the inner wall of the connecting tube 4, and the moving block 22 is slidably arranged in the chamber formed by the blocking block 6 and the baffle ring 402. In the initial state, the spring 23 is in a compressed state, and the spring 23 in the compressed state will push the moving block 22 to fit with the baffle ring 402. At this time, the moving block 22 divides the connecting tube 4 into two groups of chambers. Combined with the above, when the mounting plate 2 is fixed, After the cylinder 3 is stably connected, when the pressure-applying assembly squeezes the air in the fixed cylinder 3, the air inside the fixed cylinder 3 will move along the connecting tube 4 toward the moving block 22, and then push the moving block 22 toward the blocking block 6, so that the spring 23 is further squeezed. By observing the scale line 401 on the connecting tube 4, the moving distance of the moving block 22 in this state is recorded. After a period of time, the position of the moving block 22 is recorded again through the connecting tube 4. By comparing the values ​​of the scale line 401 under the two position states, the sealing performance of the sealing ring 12 can be determined.

[0041] Specifically, the sealing detection mechanism can also be inspected by arranging a pressure sensor in the fixed tube 3. After a period of time, if the value of the pressure sensor changes, it indicates that the sealing ring 12 is leaking.

[0042] However, the pressure sensor is easily affected by temperature, humidity, air pressure, etc. when in use, so the final detection effect is prone to deviation. In the present invention, the above-mentioned mechanical structures cooperate with each other, so that when performing a leakage simulation test on the sealing ring 12, the final result will not deviate due to environmental changes in the middle, thereby improving the accuracy of the test results.

[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 , a sealing anti-leakage simulation device in an alkaline electrolysis environment, also includes a linkage component arranged in the casing 1, the linkage component includes a reciprocating structure and a driving member, the reciprocating structure can drive the driving member to rotate, and when the driving member rotates, it can successively drive the lifting component and the pressure component to move, and when the pressure component moves, the pressure component can compress the air in the fixed cylinder 3, and by observing the sealing detection structure, the sealing ring 12 placed on the mounting plate 2 can be judged for its sealing performance.

[0044] The driving member includes a driving rod 7 rotatably installed in the casing 1, a lifting ring 8 is sleeved on the driving rod 7, a reciprocating plate 21 is arranged on the lifting ring 8, and a protrusion 801 is formed on the inner wall of the lifting ring 8, and the protrusion 801 is slidably arranged in an interlocking groove body opened on the outer wall of the driving rod 7, and the driving rod 7 is connected to the screw rod 11 and the turntable 17 through a first linkage member and a second linkage member respectively.

[0045] For details, please refer to Fig.10 Two sets of clamping rods 2102 are symmetrically arranged along the length direction of the reciprocating plate 21 on one side away from the driving rod 7. The clamping rods 2102 are slidably arranged in the clamping grooves provided on the inner wall of the casing 1. Under the cooperation between the clamping grooves and the clamping rods 2102, the reciprocating plate 21 can only drive the lifting ring 8 to lift and lower along the axial direction of the driving rod 7, and then drive the driving rod 7 to rotate. Subsequently, under the cooperation of the first linkage member and the second linkage member, the lifting assembly and the pressure assembly are driven to move in turn, thereby completing the leakage-proof simulation test of the sealing ring 12.

[0046] The reciprocating structure includes a pulley 20 rotatably installed in the casing 1, and two groups of pulleys 20 are arranged along the height direction of the casing 1. A belt 19 is arranged between the two groups of pulleys 20. A trigger rod 1901 is arranged on the belt 19, and the trigger rod 1901 is slidably arranged in a movable groove 2101 opened on the reciprocating plate 21.

[0047] Preferably, see Figure 2 , Fig. 9 Any one of the above-mentioned pulleys 20 is coaxially fixedly connected to the output shaft of the motor arranged in the casing 1. In the initial state, the lifting ring 8 is close to the bottom of the casing 1, and the motor is started. The motor output shaft drives the pulley 20 to rotate continuously in the same direction, and then forces the belt 19 to rotate. When the belt 19 rotates, the trigger rod 1901 can slide in the moving groove 2101. During the sliding process, the contact and extrusion of the trigger rod 1901 on the groove wall of the moving groove 2101 can force the reciprocating plate 21 to rise along the axial direction of the driving rod 7 until the reciprocating plate 21 moves to the highest point, and the motor stops working.

[0048] During the rising process of the above-mentioned reciprocating plate 21, the cooperation between the lifting ring 8 and the interlocking groove body can drive the driving rod 7 to rotate counterclockwise first. During rotation, the first driving member drives the lifting assembly to move and seal the fixed cylinder 3; forcing the driving rod 7 to rotate clockwise. During rotation, the pressure-applying assembly moves, which can compress the air in the fixed cylinder 3, and cooperate with the sealing detection structure. After a period of time, the sealing performance of the sealing ring 12 can be judged by observing the sealing detection structure.

[0049] In particular, the above-mentioned lifting assembly can also be replaced by components such as electric telescopic rods and cylinders. However, when using electric telescopic rods and cylinders, both need to cooperate with other linkage structures, and the electric telescopic rods and cylinders require a relatively large installation space when installed. From the perspective of the overall portability of the device, the cooperation between the belt 19 and the reciprocating plate 21 can reduce the space occupancy of the device to a certain extent. At the same time, from the perspective of device maintenance, the lifting assembly in the present invention has a relatively low maintenance cost compared to the electric telescopic rod or cylinder.

[0050] The engaging groove body includes a first spiral groove 701 opened on the outer wall of the driving rod 7, and the end of the first spiral groove 701 away from the bottom of the housing 1 is connected to a vertical groove 702, and the end of the vertical groove 702 away from the first spiral groove 701 is connected to a second spiral groove 703 opened on the outer wall of the driving rod 7.

[0051] For details, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 7 , Fig. 9 The spiral directions of the first spiral groove 701 and the second spiral groove 703 are opposite. Figure 4The first spiral groove 701 is opened around the driving rod 7 clockwise, and the second spiral groove 703 is opened around the driving rod 7 counterclockwise. The second spiral groove 703 is only opened half a circle along the circumferential direction of the driving rod 7, while the first spiral groove 701 is opened multiple circles along the outer wall of the driving rod 7.

[0052] For further information, see Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig.10 The first linkage member includes a first driving wheel 9 coaxially fixedly connected to the driving rod 7, and a first driven wheel 10 coaxially fixedly connected to the screw rod 11. The first driving wheel 9 cooperates with the first driven wheel 10 to drive the screw rod 11 to rotate.

[0053] The second linkage member includes a second driving wheel 14 coaxially fixedly connected to the driving rod 7, and a second driven wheel 15 rotatably installed in the housing 1, the second driven wheel 15 is connected to the turntable 17 through a bevel gear set 16, and the second driven wheel 15 cooperates with the second driving wheel 14 to drive the turntable 17 to rotate.

[0054] For details, please refer to Figure 7 The bevel gear set 16 includes a first bevel gear and a second bevel gear. The first bevel gear is rotatably mounted in the housing 1 , and the second bevel gear is coaxially fixedly connected to the rotating disk 17 .

[0055] Preferably, see Figure 6 , Figure 7 The outer walls of the first driving wheel 9 and the second driving wheel 14 are respectively provided with a plurality of groups of pawls equidistantly along their circumferential directions, and the first driving wheel 9 and the second driving wheel 14 are connected to the pawls through spring plates. Under the connecting action of the spring plates, the pawls are always in an open state. Correspondingly, the first driven wheel 10 and the second driven wheel 15 are respectively provided with ratchet teeth adapted to the pawls on the first driving wheel 9 and the second driving wheel 14 along their circumferential directions.

[0056] In particular, see Figure 4 The setting directions of the pawls on the first driving wheel 9 and the second driving wheel 14 are opposite. In detail, the pawls of the second driving wheel 14 are arranged clockwise around the second driving wheel 14, and the pawls of the first driving wheel 9 are arranged counterclockwise around the first driving wheel 9. The corresponding first driven wheel 10 and the second driven wheel 15 have opposite tooth directions.

[0057] In combination with the above, in the initial state, when the mounting plate 2 is away from the fixed cylinder 3, the reciprocating plate 21 drives the lifting ring 8 to approach the bottom of the housing 1. At this time, the protrusion 801 is located at the stroke end of the first spiral groove 701. After the sealing ring 12 is placed on the mounting plate 2, the motor is started, and the belt 19 rotates. Then, the reciprocating plate 21 drives the lifting ring 8 to rise along the axial direction of the driving rod 7 under the cooperation of the trigger rod 1901 and the moving groove 2101. During the rising process, the contact and extrusion of the protrusion 801 on the groove wall of the first spiral groove 701 can force the driving rod 7 to rotate counterclockwise (combined with Figure 4 ), at this time, the first driving wheel 9 and the first driven wheel 10 enter into a meshing transmission state, which can force the first driven wheel 10 to drive the screw 11 to rotate clockwise, thereby driving the mounting plate 2 to move toward the fixed cylinder 3. During this process, the second driving wheel 14 that rotates counterclockwise following the driving rod 7 does not enter into a meshing transmission state with the second driven wheel 15, so the position of the piston disk 1802 is always maintained away from the mounting disk 2.

[0058] As the lifting ring 8 continues to rise, when the protrusion 801 separates from the first spiral groove 701 and combines with the vertical groove 702, the screw rod 11 drives the mounting plate 2 to rise to the highest point to seal the fixed cylinder 3, and then the lifting ring 8 that continues to rise will drive the protrusion 801 to slide in the vertical groove 702, and the driving rod 7 remains stationary.

[0059] When the protrusion 801 is combined with the second spiral groove 703, the lifting ring 8 continues to rise under the drive of the reciprocating structure, and the contact and extrusion generated by the protrusion 801 on the groove wall of the second spiral groove 703 can force the driving rod 7 to rotate clockwise. At this time, the clockwise rotating second driving wheel 14 and the second driven wheel 15 enter into a meshing transmission state, which can drive the second driven wheel 15 to rotate counterclockwise. Then, the first bevel gear and the second bevel gear enter into a meshing transmission state, which can drive the turntable 17 to rotate. When the turntable 17 continues to rotate in the same direction, the protrusion 1701 can slide along the slide groove 1801. During the sliding process, the contact and extrusion generated by the protrusion 1701 on the groove wall of the slide groove 1801 can force the lifting plate 18 to drive the piston disk 1802 to move toward the mounting disk 2, thereby compressing the air in the fixed cylinder 3.

[0060] When the reciprocating plate 21 moves to the highest point, the motor stops. At this time, the position of the piston disc 1802 does not change due to the cooperation between the protruding column 1701 and the lifting plate 18. At this time, the position of the moving block 22 is recorded using the scale line 401. After a period of time, the position of the moving block 22 is recorded again using the scale line 401. By comparing the values ​​of the two scale lines 401, the sealing performance of the sealing ring 12 can be determined.

[0061] The present invention also proposes a simulation method for a sealing member leakage prevention simulation device in an alkaline electrolysis environment, using the sealing member leakage prevention simulation device in an alkaline electrolysis environment as described above, comprising the following steps: Step 1: In the initial state, the mounting plate 2 is separated from the fixing cylinder 3, and the lifting plate 18 is away from the mounting plate 2. When in use, the sealing ring 12 is first placed on the mounting plate 2, and then the motor is started, and the reciprocating structure moves, which can drive the driving rod 7 to rotate continuously in the same direction; Step 2: During the rotation of the driving rod 7, the first linkage is first triggered to drive the screw 11 to rotate, and then drives the mounting plate 2 to move toward the fixed cylinder 3, until the mounting plate 2 is combined with the fixed cylinder 3 to form a closed environment in the fixed cylinder 3, the first linkage stops, and the second linkage is triggered to drive the pressure component to move, and then the lifting plate 18 is lowered, thereby compressing the air in the fixed cylinder 3. At this time, the compressed air will push the moving block 22 to rise; Step 3: The reciprocating structure stops moving.
