[0021] 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.

[0022] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0023] According to the following Figure 1-Figure 15 The invention describes an alkaline electrolytic cell sealing gasket performance detection device provided in an embodiment of the invention.

[0024] See also Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an alkaline electrolytic cell sealing gasket performance detection device, including a frame assembly 3, a detection seat 4 and a main pressure plate 8, the frame assembly 3 includes a base 31, side frames 32 arranged on both sides above the base 31 and a top frame 33 located between the upper ends of the side frames 32, the detection seat 4 is located on the upper surface of the base 31, the main pressure plate 8 is located below the top frame 33, the sealing gasket is placed on the upper surface of the detection seat 4, and a pressure cylinder 6 is provided on the top frame 33, which can move the main pressure plate 8 up and down. When the pressure cylinder 6 applies downward pressure, the main pressure plate 8 can press down the sealing gasket, thereby measuring the compression resistance and rebound performance of the sealing gasket.

[0025] Combination Figure 3-Figure 6 as well as Figure 8 As shown, heating rods 15 are provided on both sides of the detection seat 4, and the heating temperatures of the heating rods 15 on both sides can be controlled separately. Heating rods 13 are provided on both sides of the main pressure plate 8, and the temperatures of the heating rods 13 on both sides can be controlled separately. The reason why the temperatures of heating rods 15 and 13 can be adjusted separately is that in the water hydrogen production equipment, the temperature on the cathode side is higher than that on the anode side. This is because the cathode is reduced during the electrolysis process, the reaction releases heat, and the temperature on the cathode side rises, while the anode undergoes an oxidation reaction, absorbs heat, and the temperature on the anode side is relatively low. The different temperatures applied by heating rods 15 and 13 to the sealing gasket can simulate the effect of different temperatures of the cathode plate and the anode plate in the alkaline electrolytic cell on the sealing gasket.

[0026] In addition, the reason why the temperatures of the heating rods 15 on both sides can also be adjusted individually is that in the water hydrogen production equipment, the temperature at the bottom of the electrolytic cell is also higher than that at the top. This is because the density of the electrolyte is greater than that of the air, and the electrolyte temperature at the bottom is relatively high. This is used to simulate the impact of different upper and lower temperatures on the sealing gasket in the water hydrogen production equipment. Similarly, the temperatures of the heating rods 13 on both sides are also set to be individually adjustable.

[0027] Therefore, the alkaline electrolytic cell sealing gasket performance detection device provided by the embodiment of the present invention can verify the compression resistance of the sealing gasket under constant temperature and pressure.

[0028] In this embodiment, Figure 7 and Figure 8 As shown, a total of six heating rods 13 are provided, three on one side as a group with the same temperature, and the remaining three on the other side as another group with the same temperature. Correspondingly, six heating rods 2 15 are provided, three on one side as a group with the same temperature, and the remaining three on the other side as another group with the same temperature.

[0029] Preferably, a heat insulating jacket 12 is provided on the periphery of the heating rod 13 and the heating rod 2 15, and an opening should be provided on the side of the heat insulating jacket 12 close to the sealing gasket to allow heat to pass through the opening.

[0030] Preferably, a heating plate 10 is assembled on the lower surface of the main pressure plate 8, and the heating plate 10 is used to transfer the heat of the heating rod 13 to the sealing gasket (the downward pressure of the main pressure plate 8 is actually transferred to the sealing gasket through the heating plate 10).

[0031] like Figure 1-Figure 7 As shown, in order to realize that the heating rod 13 and the heating rod 2 15 can adapt to sealing gaskets of different diameters, that is, the heating rod 13 can always be located on the upper surface of the sealing gasket, and the heating rod 2 15 can always be located on the lower surface of the sealing gasket, the heating rod 13 and the heating rod 2 15 are both set to a movable state, as follows: ① Regarding the movement of the heating rod 215, refer to Figure 5 and Figure 6Guide columns 2 are arranged on both sides of the frame assembly 3, and a moving assembly 14 is arranged in the detection seat 4. The moving assembly 14 is used to adjust the diameter of the circle formed by all the heating rods 15, so that all the heating rods 15 can be located directly above the sealing rings of different diameters. A thrust assembly 11 that can drive the moving assembly 14 to work is arranged at the lower end of the guide column 2, and a driving assembly 16 for driving the guide column 2 to rotate is arranged above the frame assembly 3 (the driving assembly 16 is a mechanism in which a motor drives a pulley to operate, and the motor is preferably a self-locking motor, and the two pulleys are respectively assembled on the upper ends of the two guide columns 2). When the driving assembly 16 rotates, it can drive the guide column 2 to rotate, and the rotation angle is different. The pushing length of the thrust assembly 11 on the moving assembly 14 is different, so that the displacement caused by the moving assembly 14 on the heating rod 15 is different, so as to adapt to the sealing gaskets of different diameters.

[0032] ② Regarding the movement of the heating rod 13, refer to Figure 3 , Figure 4 as well as Figure 7 A moving component 7 is provided on the main pressure plate 8. The moving component 7 is used to adjust the diameter of the circle formed by all the heating rods 13, so that the heating rods 13 can adapt to sealing rings of different diameters. In order to realize the adjustment of the moving component 7 to the heating rods 13, thrust components 9 are provided on both sides of the main pressure plate 8. The guide column 2 is provided with a groove structure that can drive the thrust component 9 to rotate during the descending process of the main pressure plate 8. The thrust component 9 rotates at different angles, and the pushing length of the moving component 7 is different, so that the displacement of the heating rod 13 caused by the moving component 7 is different, so as to adapt to sealing gaskets of different diameters.

[0033] In order to achieve the purpose of different rotation angles of the thrust assembly 9, please refer to Figure 10-12 As shown, the groove structure includes an annular groove 21, a first vertical groove 22, a spiral groove 23 and a second vertical groove 24. The thrust assembly 9 includes an assembly cylinder 94, a middle cylinder 91 and a sliding column 95.

[0034] The annular groove 21 is provided on the outer surface of the upper section of the guide column 2, the first vertical groove 22 is provided below the annular groove 21, there are four groups of the first vertical grooves 22, and they are evenly arranged on the outer surface of the guide column 2, the spiral groove 23 is provided at the lower end of the first vertical groove 22, and the four spiral grooves 23 have the same height and different spirality, the second vertical groove 24 is located at the lower end of the spiral groove 23, and the lower end of the second vertical groove 24 is not higher than the upper surface of the detection seat 4. The assembly cylinder 94 is rotatably installed on both sides of the main pressure plate 8 through the bearing along the axial direction of the main pressure plate 8, the middle cylinder 91 is provided at the upper end of the assembly cylinder 94, and a push vane 92 is fixed on one side of the middle cylinder 91, and the sliding column 95 is provided on the inner wall of the middle cylinder 91 close to the side of the main pressure plate 8, the main pressure plate 8 can slide along the guide column 2, and the sliding column 95 can slide along the groove structure.

[0035] In this embodiment, when the slide post 95 is located in the first vertical groove 22 and slides downward, the push blade 1 92 on one side is located directly behind the guide post 2, and the push blade 1 92 on the other side is located directly in front of the guide post 2. As the slide post 95 slides into the spiral groove 23, it is pushed by the spiral groove 23, and the assembly cylinder 94 can rotate, so that the push blade 1 92 performs a pushing action. After the pushing is completed, the slide post 95 reaches the second vertical groove 24 to maintain the angle state of the push blade 1 92 after rotation. When the push blade 1 92 rotates to different angles, the pushing amount of the moving component 1 7 is different, so that the displacement of the heating rod 13 is different. The four types of spiral grooves 23 represent the rotation angles of the four types of push blades 1 92, the four types of rotation angles of the push blades 1 92 represent the displacement of the four types of heating rods 13, and the displacement of the four types of heating rods 13 represent the four diameters of the sealing pads.

[0036] Preferably, a limiting cylinder 93 is provided at the lower end of the assembly cylinder 94 to limit the assembly cylinder 94 from separating from the main pressure plate 8 .

[0037] It should be noted that the number of spiral turns of one of the spiral grooves 23 is 0, that is, in fact, this spiral groove 23 is a straight groove. When the sliding column 95 reaches this straight groove, the push blade 92 will not rotate. At this time, the heating rod 13 is located at the outermost periphery inside the main pressure plate 8. At this time, it is the maximum threshold of the sealing gasket diameter that the heating rod 13 can adapt to; the number of spiral turns of the remaining spiral grooves 23 can be selected as 0.15 turns, 0.2 turns, and 0.25 turns. The sealing gasket corresponding to the spiral groove 23 with 0.25 spiral turns has the smallest diameter. For example, the diameter of the sealing gasket corresponding to 0 spiral turns is 2200 mm, and the corresponding sealing gasket diameter when the number of spiral turns is 0.25 is 1000 mm.

[0038] It should be noted that the more spiral grooves 23 are provided, the larger the diameter of the sealing gasket that can be accommodated.

[0039] When the position of the heating rod 13 needs to be adjusted, the entire main pressure plate 8 is lifted upward by using the pressure cylinder 6 until the slide post 95 reaches the position of the annular groove 21, and the driving assembly 16 is rotated to drive the guide column 2 to rotate until the slide post 95 reaches the position of the corresponding spiral groove 23 in the annular groove 21, and the driving assembly 16 stops working. At this time, when the slide post 95 moves downward with the main pressure plate 8 and reaches the position of the spiral groove 23, the pushing angle of the push blade 92 driven by the spiral groove 23 can make the moving assembly 7 drive the heating rod 13 to move to the top of the sealing gasket. Preferably, it is best to set a marking line on the upper end of the outer surface of the guide column 2. For example, when the diameter of the sealing gasket adapted to the heating rod 13 at the outermost edge is 2200mm, 2200mm is marked above the first vertical groove 22 opposite to the spiral groove 23 with 0 spiral turns, so as to remind the staff that when the sealing gasket of 2200mm needs to be tested, the slide post 95 needs to be aligned with the first vertical groove 22 corresponding to the spiral groove 23 with 0 spiral turns.

[0040] In order to achieve the purpose of the above-mentioned moving component 7 being able to adjust the position of the heating rod 13, as Figure 4 , Figure 13-Figure 15 As shown, a lower receiving groove 82 is opened in the diameter direction in the area of ​​the lower surface of the main pressure plate 8 opposite to the heating rod 13, and an upper guide groove 81 is opened in the area of ​​the upper surface of the main pressure plate 8 opposite to the lower receiving groove 82; the moving component 7 includes a moving seat 71 and a rotating disk 72.

[0041] Specifically, the movable seat 71 is located on the upper surface of the main pressure plate 8 and is opposite to the heating rod 13. A connecting block 75 is fixed between the movable seat 71 and the heating rod 13. The rotating plate 72 is rotatably installed on the upper surface of the main pressure plate 8 and is concentric with the main pressure plate 8. A hinged rod 73 is hinged between the rotating plate 72 and the movable seat 71.

[0042] In the present embodiment, the two moving seats 71 opposite to the thrust assembly 9 serve as the main driving blocks. The thrust assembly 9 can push the main driving blocks. When the main driving blocks are pushed, they can push the rotating disk 72 through their own hinged rods 73. When the rotating disk 72 rotates, it can pull all the moving seats 71 to move, thereby adjusting the positions of all the moving seats 71. The moving seats 71 can drive all the heating rods 13 to move synchronously through the connecting blocks 75, thereby adjusting the positions of each heating rod 13.

[0043] Preferably, a spring 74 is also provided, and the spring 74 is fixed between the heating rod 13 and one end of the lower receiving groove 82 close to the center of the main pressure plate 8. When the heating rod 13 is gradually pushed to a position close to the center of the main pressure plate 8, the spring 74 is in a compressed state. When the moving seat 71 loses pressure, the spring 74 rebounds, so that the heating rod 13 is pushed back to the maximum diameter. Further, a guide rod can be provided for the spring 74.

[0044] It should be noted that the structure and principle of the thrust assembly 1 9 are similar to those of the thrust assembly 2 11, and the structure and principle of the moving assembly 1 7 and the moving assembly 2 14 are similar. Figure 5 and Figure 6The difference is that the thrust assembly 11 is directly fixed on the guide column 2, which includes a middle cylinder 111 fixed on the lower end of the guide column 2 and a push blade 112 fixed on the middle cylinder 111. When the above-mentioned staff adjusts the spiral groove 23 on the guide column 2 to align with the sliding column 95 through the driving assembly 16, the actual deflection angle of the push blade 112 has been adjusted, that is, the position of the push blade 112 has been adjusted when the main pressure plate 8 has not been pressed down. The moving component 14 includes a rotating disk 143 rotatably arranged in the detection seat 4, and an articulated rod 142 is assembled between the rotating disk 143 and the insulating jacket 12 outside the heating rod 15. The outer ends of the heating rods 15 on both sides are provided with force-bearing parts for bearing the thrust of the push blades 112 on the heating rods 15. The two groups of heating rods 15 subjected to the thrust can gradually approach the center of the detection seat 4, compress the spring 141, and push the rotating disk 143 to rotate through the articulated rod 142 on itself, so that the rotating disk 143 can drive the remaining heating rods 15 to move through the remaining articulated rods 142.

[0045] Preferably, a clearance groove 421 for evading the second pusher blade 112 is provided on both sides of the detection seat 4 .

[0046] Since the main pressure plate 8 has a large diameter, in order to avoid the situation where the pressure caused by the main pressure plate 8 when pressing down is concentrated in the middle area and the pressure in the sealing gasket area is reduced, the main pressure plate 8 is used as the main pressure plate 8. Figure 1-Figure 4 as well as Figure 7-Figure 9 As shown, the alkaline electrolytic cell sealing gasket performance detection device provided by the embodiment of the present invention also includes a downward pressing connection component 5, which includes an idler plate 51. The idler plate 51 has a cavity at the bottom, and a first slide rod 53 parallel to the upper guide groove 81 is provided in the cavity. A first slide sleeve 54 is slidably provided on the first slide rod 53. A connecting rod 52 is fixedly connected between the first slide sleeve 54 and the movable seat 71. The first slide rod 53 can move with the movable seat 71. The lower end of the piston rod of the pressure cylinder 6 is fixedly connected to the idler plate 51 to push the main pressure plate 8 downward or pull it upward through the downward pressing connection component 5.

[0047] In this embodiment, when the pressure cylinder 6 is extended, it can push the idle plate 51 downward, and the idle plate 51 applies pressure to the movable seat 71 through the connecting rod 52. Since the positions of the movable seat 71 and the heating rod 13 are always located directly above the sealing gasket, the movable seat 71 serves as the force application point of the downward pressing connecting assembly 5 on the main pressure plate 8. The pressure exerted on the main pressure plate 8 is always located directly above the sealing gasket, thereby making the pressure of the main pressure plate 8 on the sealing gasket more precise.

[0048] Preferably, the outer surface of the guide column 2 is provided with annular scale lines, and the initial height and the height after compression of the sealing gasket can be read through the scale lines on the guide column 2, thereby obtaining the compressed size of the sealing gasket. The height of the sealing gasket after the main pressure plate 8 upwardly separates from the sealing gasket and rebounds can also be read, thereby knowing the resilience performance of the sealing gasket.

[0049] like Figure 6 As shown, in order to obtain the compression rebound and creep relaxation performance of the sealing gasket under different materials, the test seat 4 includes a fixed seat 42, and the upper surface of the fixed seat 42 is provided with a accommodating cavity 422. The fixed seat 42 accommodates a pressure plate 41, and the pressure plate 41 is engaged with the fixed seat 42, so that the pressure plate 41 can be removed from the fixed seat 42 to replace the pressure plate 41, thereby facilitating the testing of the compression rebound and creep relaxation performance of the sealing gasket.

[0050] Preferably, four groups of concentric waterline simulation rings 411 are provided on the upper surface of the pressure plate 41 to simulate the waterline structure on the pole frame.

[0051] The alkaline electrolytic cell sealing gasket performance detection device provided in the embodiment of the present invention can also detect the sealing performance of the sealing gasket, which includes a leakage detection component 1, combined with Figure 1 , Figure 5 and Figure 6 As shown, the air leakage detection assembly 1 includes an air hole 105 , a branch pipe 103 and a main pipe 102 .

[0052] The air holes 105 are opened between the same group of waterline simulation rings 411, and there are four groups of branch pipes 103. One end of the branch pipe 103 is inserted into the fixing seat 42 from one side of the fixing seat 42 and enters the air hole 105. A solenoid valve 104 is provided on the branch pipe 103. One end of the branch pipe 103 away from the fixing seat 42 is fixedly connected to the main pipe 102, and a pressure gauge 101 is provided at the upper end of the main pipe 102; an air supply pump installation cavity 43 is provided at the center of the pressure plate 41 and the fixing seat 42, and the air supply pump installation cavity 43 is used to install the air supply pump, and the air inlet end of the air supply pump should pass through the detection seat 4 along one side of the detection seat 4, so that it absorbs gas outside the detection seat 4.

[0053] In the present embodiment, the solenoid valve 104 corresponding to the air hole 105 corresponding to the sealing gasket of the corresponding size is first opened, and the other solenoid valves 104 are closed. After the main pressure plate 8 is pressed down, the air supply pump can suck air from the outside and blow it to the sealing gasket. When the sealing gasket has excellent sealing performance, it means that the sealing gasket is not leaking, and the air path formed by the air hole 105, the branch pipe 103 and the main pipe 102 will not take in air, then the pointer of the pressure gauge 101 will not change, otherwise it will change or change significantly.

[0054] When in use (working), first determine the diameter of the sealing gasket. For example, the diameter of the batch of sealing gaskets to be tested is 1000mm. Use the pressure cylinder 6 to pull the main pressure plate 8 upward to make the slide post 95 reach the position of the annular groove 21. At this time, the driving assembly 16 drives the two guide posts 2 to rotate until the first vertical groove 22 on the spiral groove 23 of the sealing gasket corresponding to 1000mm is aligned with the slide post 95. The driving assembly 16 stops working. During the rotation of the guide post 2, the lower end of the guide post 2 is The push blade 112 pushes the heating rod 15. The two groups of heating rods 15 that are pushed can gradually approach the center of the circle of the detection seat 4, compress the spring 141, and push the rotating disk 143 to rotate through the hinge rod 142 on itself, so that the rotating disk 143 can drive the remaining heating rods 15 to move through the remaining hinge rods 142, so that all the heating rods 15 can be located directly below the 1000mm sealing gasket. Next, the pressing operation is carried out. When pressing down, the pressure cylinder 6 extends. The main pressure plate 8 is pushed downward by pressing the connecting assembly 5. At this time, the sliding column 95 slides inside the first vertical groove 22 until the sliding column 95 reaches the inside of the spiral groove 23. It is pushed by the spiral groove 23 and the assembly cylinder 94 can rotate, so that the push blade 92 can push. During the pushing, the two moving seats 71 opposite to the push blade 92 act as the main driving blocks. The push blade 92 can push the main driving block. When the main driving block is pushed, it can push the rotating disk 72 through its own hinged rod 73. When the rotating disk 72 rotates, it can pull all the moving seats 71 to move, thereby adjusting the positions of all the moving seats 71. The moving seat 71 can drive all the heating rods 13 to move synchronously through the connecting block 75, thereby adjusting the positions of each heating rod 13, so that the positions of each heating rod 13 reach directly above the sealing gasket. As the main pressure plate 8 continues to move downward, the sliding column 95 reaches the inside of the second vertical groove 24, thereby maintaining the rotation angle of the push blade 92 to maintain the position of the heating rod 13.

[0055] After the main pressure plate 8 is pressed down onto the sealing gasket, the heating rod 13 and the heating rod 2 15 can heat the sealing gasket with high precision. The thickness of the sealing gasket after compression can be obtained from the scale line on the guide column 2. At the same time, air can be continuously sucked in from the outside through the air supply pump and blown toward the sealing gasket. When the sealing gasket has excellent sealing performance, the pointer of the pressure gauge 101 will not change, otherwise it will change or change significantly.

[0056] After the first sealing gasket of the same batch is tested, the main pressure plate 8 can be lifted by shortening the pressure cylinder 6, and the lifting height should be the height at which the slide column 95 does not enter the spiral groove 23. After lifting, the resilience performance of the sealing gasket can also be obtained from the scale line on the guide column 2. Then, another 1000mm sealing gasket to be tested can be placed on the test seat 4.
