[0014] The present invention also discloses a glass plate liquid level gauge detection method, which uses the above-mentioned glass plate liquid level gauge detection device and comprises the following steps:

[0015] S1: First connect the second one-way valve to the external water pipe, then pull the T-type pull plate, and drive the piston rod through the T-type pull plate to pump water into the liquid storage tank through the second one-way valve. When the T-type pull plate moves to the farthest distance from the liquid storage tank, the piston rod is limited by the positioning pressure piece;

[0016] S2: buckle the first connecting valve on the main body of the glass plate liquid level gauge into the inner side of the connecting cover, and in this process, quickly limit the first connecting valve by a locking clamp;

[0017] S3: Open the first connecting valve, operate the positioning pressurizing member to make the piston rod squeeze the aqueous solution inside the liquid storage tank, so that the aqueous solution inside the liquid storage tank enters the main body of the glass plate level gauge through the first one-way valve, the drain pipe, the connecting cover, and the first connecting valve, so that the aqueous solution inside the liquid storage tank fills the main body of the glass plate level gauge, close the second connecting valve, and squeeze the aqueous solution inside the liquid storage tank at the same time, so that the aqueous solution inside the main body of the glass plate level gauge is subjected to a certain squeezing force;

[0018] S4: After leaving it for a while, observe the aqueous solution inside the liquid storage tank. If the aqueous solution inside the liquid storage tank is completely discharged from the liquid storage tank under the action of the positioning pressure piece, it means that the sealing of the glass plate liquid level gauge body is poor. If there is still aqueous solution inside the liquid storage tank, it means that the sealing of the glass plate liquid level gauge body is strong. In this way, the sealing of the glass plate liquid level gauge body can be detected.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting a positioning pressurizing member and a locking card connecting member, the piston rod is pulled so that the aqueous solution fills the liquid storage tank. At the same time, the limit card pin will be buckled into the positioning hole under the action of the elastic restoring force of the first reset spring, so as to limit the piston rod. Then, the bottom of the first connecting valve is limited by the locking card connecting member, and then the first connecting valve is opened, and then the limit card pin is pulled. When the aqueous solution fills the main body of the glass plate liquid level gauge, the second connecting valve is closed and placed for a period of time. If the sealing performance of the main body of the glass plate liquid level gauge is poor, the aqueous solution inside the liquid storage tank will be pushed by the piston rod and finally discharged from the main body of the glass plate liquid level gauge. At this time, the first moving contact piece and the first static contact piece are attached to the buzzer, and the buzzer is powered on. Similarly, if the buzzer does not work during the placement process, it means that the sealing performance of the main body of the glass plate liquid level gauge is good. In this way, the sealing performance of the main body of the glass plate liquid level gauge can be clearly and correctly known, which is simple to operate and reduces the labor intensity of the staff.

[0021] 2. By setting a locking card connector, the flange at the bottom of the first connecting valve or the second connecting valve is buckled into the connecting cover, and the main body of the glass plate liquid level gauge is pressed. When the flange moves below the extrusion connecting block, the end of the extrusion connecting block close to the truncated cone guide block will lose the limit and recover under the action of the second reset spring, so that the second reset spring limits the top of the flange. When the limit card pin is pulled to separate the limit card pin from the positioning hole, the second moving contact piece separates from the second static contact piece as the limit card pin moves, so that the solenoid valve is powered off and closed, so that the aqueous solution inside the piston tube loses the flow space, so as to limit the piston tube. In this way, the main body of the glass plate liquid level gauge can be quickly installed with a limit, so as to improve the overall detection efficiency of the equipment.

The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0033] See also Figures 1 to 8 In an embodiment of the present invention, a device for detecting a glass plate liquid level gauge includes a liquid storage tank 1, wherein a piston rod 2 extending to the outside of the liquid storage tank 1 is inserted into the interior of the liquid storage tank 1, a T-shaped pull plate 3 is installed at one end of the piston rod 2 away from the liquid storage tank 1, a first one-way valve 406 is installed at one end of the liquid storage tank 1 away from the T-shaped pull plate 3, a discharge pipe 407 is connected to one end of the first one-way valve 406 away from the liquid storage tank 1, a connecting cover 408 is installed on the top of the discharge pipe 407, a locking card connector is provided on the inner side of the connecting cover 408, and the connecting cover 408 is connected to a first connecting valve 411 through the locking card connector, a glass plate liquid level gauge body 412 is provided on the first connecting valve 411, a second connecting valve 416 is installed at one end of the glass plate liquid level gauge body 412 away from the first connecting valve 411, a positioning and pressurizing member is provided on the piston rod 2, and a second one-way valve 426 is installed at the bottom of one end of the liquid storage tank 1 close to the first one-way valve 406.

[0034] In this embodiment: when testing the glass plate liquid level gauge, first connect the second one-way valve 426 to the external water pipe, then pull the T-shaped pull plate 3, and drive the piston rod 2 through the T-shaped pull plate 3 to draw water into the liquid storage tank 1 through the second one-way valve 426. When the T-shaped pull plate 3 moves to the farthest distance from the liquid storage tank 1, the piston rod 2 is limited by the positioning pressure piece, and then the first connecting valve 411 on the glass plate liquid level gauge body 412 is buckled into the inner side of the connecting cover 408. In this process, the first connecting valve 411 is quickly limited by the locking card connecting piece, and the first connecting valve 411 is opened. The positioning pressure piece is operated to make the piston rod 2 squeeze the aqueous solution inside the liquid storage tank 1, so that the aqueous solution inside the liquid storage tank 1 passes through the first one-way valve 406 and the discharge The liquid pipe 407, the connecting cover 408, and the first connecting valve 411 enter the glass plate liquid level gauge body 412, so that the aqueous solution inside the liquid storage tank 1 fills the glass plate liquid level gauge body 412, and the second connecting valve 416 is closed. At the same time, the aqueous solution inside the liquid storage tank 1 is squeezed, so that the aqueous solution inside the glass plate liquid level gauge body 412 is subjected to a certain squeezing force. After being left for a period of time, the aqueous solution inside the liquid storage tank 1 is observed. If the aqueous solution inside the liquid storage tank 1 is completely discharged from the liquid storage tank 1 under the action of the positioning pressure member, it means that the sealing of the glass plate liquid level gauge body 412 is poor. If there is still aqueous solution in the liquid storage tank 1, it means that the sealing of the glass plate liquid level gauge body 412 is strong. In this way, the sealing of the glass plate liquid level gauge body 412 can be detected.

[0035] Please refer to Figure 1 , Figure 7 The drainage end of the second one-way valve 426 is connected to the liquid storage tank 1, and the water inlet end of the first one-way valve 406 is connected to the liquid storage tank 1.

[0036] In this embodiment, this structure is provided to allow the aqueous solution entering the liquid storage tank 1 to flow in one direction, thereby achieving the effect of injecting water into the piston rod 2 .

[0037] Please refer to Figure 1 , Figure 4 , Figure 5 , Figure 7 The positioning and pressurizing member includes a guide tube 404 installed at the bottom of the liquid storage tank 1 and located on one side of the second one-way valve 426, a limiting plug rod 403 located below the piston rod 2 and connected to the T-type pull plate 3 is inserted inside the guide tube 404, a first moving contact piece 429 located inside the guide tube 404 is installed at one end of the limiting plug rod 403 away from the T-type pull plate 3, a first static contact piece 430 located at the same horizontal position as the first moving contact piece 429 is installed on the inner wall of the guide tube 404, a buzzer 415 is installed on the top of the liquid storage tank 1, a positioning hole 428 is opened at one end of the piston rod 2 close to the liquid storage tank 1, a limiting pin 427 located above the piston rod 2 and extending to the inside of the positioning hole 428 is inserted at the top of the liquid storage tank 1, a first return spring 402 connected to the liquid storage tank 1 is arranged on the top of the limiting pin 427, and a pulling spring 401 connected to the liquid storage tank 1 and located on both sides of the piston rod 2 is arranged on the T-type pull plate 3.

[0038] In this embodiment: when the second one-way valve 426 is connected to the external water pipe and the bottom of the first connecting valve 411 is limited, the piston rod 2 is pulled to move the piston rod 2 away from the liquid storage tank 1. At this time, the aqueous solution in the external water pipe will enter the inner side of the liquid storage tank 1 through the second one-way valve 426. At the same time, the T-type pull plate 3 drives the pull spring 401 to extend. In this process, the bottom end of the limit pin 427 is always in contact with the top of the piston rod 2 under the action of the elastic restoring force of the first return spring 402. As the piston rod 2 moves, When the positioning hole 428 is aligned with the limiting latch 427, the limiting latch 427 will be buckled into the positioning hole 428 under the action of the elastic restoring force of the first return spring 402, so as to limit the piston rod 2, and then the bottom of the first connecting valve 411 is limited by the locking clamp, and then the first connecting valve 411 is opened, and then the limiting latch 427 is pulled to separate the limiting latch 427 from the positioning hole 428. At this time, the piston rod 2 will move toward the liquid storage tank 1 under the action of the elastic restoring force of the pull spring 401, so as to release the liquid storage tank. The aqueous solution inside the liquid tank 1 is injected into the inner side of the glass plate liquid level gauge body 412 through the drain pipe 407 and the connecting cover 408. During this process, the first moving contact piece 429 moves toward the first static contact piece 430 along with the movement of the limit plug rod 403 and the T-type pull plate 3. When the aqueous solution fills the glass plate liquid level gauge body 412, the pull spring 401 has not yet fully recovered. At this time, the piston rod 2 continues to apply thrust to the aqueous solution inside the liquid storage tank 1, so as to pressurize the aqueous solution inside the glass plate liquid level gauge body 412. After that, if it is left for a period of time, The sealing performance of the glass plate liquid level gauge body 412 is poor. At this time, the aqueous solution inside the liquid storage tank 1 will be pushed by the piston rod 2 and finally discharged from the glass plate liquid level gauge body 412. At this time, the first moving contact piece 429 and the first static contact piece 430 are in contact with each other, and the buzzer 415 is powered on and operates. Similarly, if the buzzer 415 does not operate during the placement process, it means that the sealing performance of the glass plate liquid level gauge body 412 is good. In this way, the sealing performance of the glass plate liquid level gauge body 412 can be clearly and correctly known. The operation is simple and the labor intensity of the staff is also reduced.

[0039] Please refer to Figure 5 The first stationary contact piece 430 is electrically connected to the buzzer 415 through a wire, and the first moving contact piece 429 is electrically connected to the external power supply through a wire.

[0040] In this embodiment, by providing this structure, the buzzer 415 operates when the first movable contact piece 429 contacts the first stationary contact piece 430 , thereby controlling the operation timing of the buzzer 415 .

[0041] Please refer to Figure 5 The bottom of the limiting pin 427 is rotatably connected with a ball through a bearing, and the diameter of the limiting pin 427 is equal to that of the positioning hole 428.

[0042] In this embodiment: this structure is provided to reduce the friction between the limit pin 427 and the piston rod 2 when the bottom of the limit pin 427 is in contact with the top of the piston rod 2, thereby increasing the service life of the limit pin 427 and the piston rod 2, and also improving the stability of the piston rod 2 when the limit pin 427 is inserted into the positioning hole 428.

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 8 The locking card connector includes a water tank 414 installed on the top of the liquid storage tank 1 and located on the side of the buzzer 415 away from the limit card pin 427, the bottom of the water tank 414 is connected to the solenoid valve 413, the inner side of the connecting cover 408 is connected to the bellows telescopic tube 422, the top of the bellows telescopic tube 422 is installed with a truncated cone guide block 421, the bottom outer wall of the truncated cone guide block 421 is installed with a positioning ring 417, the outer wall of the connecting cover 408 is movably sleeved with a push ring 409, the inner side of the connecting cover 408 is plugged with an extrusion block 419 extending to the outside of the connecting cover 408, the extrusion block 419 is located above the positioning ring 417, the extrusion block 419 is provided with a second return spring 420 connected to the outer wall of the connecting cover 408, and the push ring 409 is connected to the outer wall of the connecting cover 408. An oblique pressure rod 410 connected to the extrusion connecting block 419 is rotatably connected to the rotating shaft, a piston tube 423 located on the outside of the corrugated telescopic tube 422 is installed at the bottom of the positioning ring 417, a guide plug rod 424 extending to the bottom of the piston tube 423 is inserted at the temporal part of the piston tube 423, a third return spring 425 connected to the bottom of the piston tube 423 is arranged on the guide plug rod 424, a connecting pipe 418 connected to the solenoid valve 413 is arranged at the bottom end of the guide plug rod 424, a limiting sleeve 405 located on the side of the buzzer 415 away from the water tank 414 is installed on the top of the liquid storage tank 1, a second static contact piece 431 is installed on the inner wall of the limiting sleeve 405, and a second moving contact piece 432 located on the inner side of the limiting sleeve 405 is arranged on one side of the limiting pin 427.

[0044] In this embodiment, when the main body 412 of the glass plate level gauge is connected to the detection device, the flange at the bottom of the first connecting valve 411 or the second connecting valve 416 is first buckled into the connecting cover 408, so that the top of the truncated cone guide block 421 fits with the flange, and then the main body 412 of the glass plate level gauge is pressed. At this time, the extrusion connecting block 419 will be squeezed by the outer inclined surface of the truncated cone guide block 421 and move in the direction away from the center of the truncated cone guide block 421. In this process, the second return spring 420 is extended, and at the same time, the extrusion connecting block 419 drives the push ring 421 through the oblique pressure rod 410. 09 moves upward, and the piston tube 423 moves downward relative to the guide rod 424 as the positioning ring 417 moves downward, thereby causing the third return spring 425 to contract, and at the same time, the aqueous solution inside the piston tube 423 is squeezed into the water tank 414 through the guide rod 424, the connecting pipe 418, and the electromagnetic valve 413. When the flange moves below the extrusion connecting block 419, the end of the extrusion connecting block 419 close to the truncated cone guide block 421 will lose its limit and recover under the action of the second return spring 420, thereby causing the second return spring 420 to limit the top of the flange, and at the same time, the third The return spring 425 applies an upward thrust to the positioning ring 417, so that the top of the truncated cone guide block 421 is fully fitted with the flange at the bottom of the first connecting valve 411. When the limit pin 427 is pulled to separate the limit pin 427 from the positioning hole 428, the second moving contact piece 432 is separated from the second static contact piece 431 as the limit pin 427 moves, so that the solenoid valve 413 is powered off and closed, so that the aqueous solution inside the piston tube 423 loses the flow space, so as to limit the piston tube 423, so that the glass plate liquid level gauge body 412 can be quickly adjusted. The limit installation is performed, so that the overall detection efficiency of the equipment can be improved. After the sealing test of the glass plate liquid level gauge body 412 is completed, the piston rod 2 is pulled to make the limit pin 427 insert into the positioning hole 428 again, and the aqueous solution fills the liquid storage tank 1 at the same time. At this time, the second moving contact piece 432 and the second static contact piece 431 contact the water tank 414, and the solenoid valve 413 is energized to open. After that, the push ring 409 can be pushed upward to make the extrusion connecting block 419 lose the obstruction to the connecting flange on the first connecting valve 411, and then the glass plate liquid level gauge body 412 that has been tested can be removed.

[0045] Please refer to Figure 2 , Figure 5 The solenoid valve 413 is electrically connected to the second stationary contact piece 431 through a wire, and the second movable contact piece 432 is electrically connected to an external power source through a wire.

[0046] In this embodiment, the opening and closing timing of the electromagnetic valve 413 is controlled by the contact between the second movable contact piece 432 and the second stationary contact piece 431 .

[0047] Please refer to Figure 3, Figure 8 A through hole having a diameter equal to that of the inner wall of the corrugated telescopic tube 422 is provided on the inner side of the truncated cone guide block 421 , and the diameter of the top of the truncated cone guide block 421 is greater than the diameter of the bottom of the truncated cone guide block 421 .

[0048] In this embodiment: by providing this structure, the truncated cone guide block 421 is caused to squeeze the extrusion connecting block 419 when it moves downward, so that the extrusion connecting block 419 is moved in a direction away from the connection cover 408 .

[0049] Please refer to Figure 3 , Figure 8 There are multiple extrusion connecting blocks 419 , and the multiple extrusion connecting blocks 419 are distributed at equal distances along the center of the push ring 409 , and the center of the push ring 409 is coaxial with the center of the connecting cover 408 .

[0050] In this embodiment: by setting this structure, multiple push rings 409 limit different positions of the bottom connecting flange of the first connecting valve 411, so as to improve the stability of the push ring 409 limiting the first connecting valve 411.

[0051] In combination with the above-mentioned device for detecting a glass plate liquid level gauge, a method for detecting a glass plate liquid level gauge is provided below, which specifically includes the following steps:

[0052] S1: First connect the second one-way valve 426 to the external water pipe, pull the piston rod 2, and make the piston rod 2 move in the direction away from the liquid storage tank 1. At this time, the aqueous solution in the external water pipe will enter the inner side of the liquid storage tank 1 through the second one-way valve 426. At the same time, the T-type pull plate 3 drives the pull spring 401 to extend. In this process, the bottom end of the limit pin 427 is always in contact with the top of the piston rod 2 under the action of the elastic restoring force of the first return spring 402. As the piston rod 2 moves, when the positioning hole 428 is aligned with the limit pin 427, the limit pin 427 will be buckled into the positioning hole 428 under the action of the elastic restoring force of the first return spring 402, so as to limit the piston rod 2.

[0053] S2: buckle the flange at the bottom of the first connecting valve 411 or the second connecting valve 416 into the connecting cover 408, so that the top of the truncated cone guide block 421 fits with the flange, and then press the glass plate liquid level gauge body 412. At this time, the extrusion connecting block 419 will be squeezed by the outer inclined surface of the truncated cone guide block 421 and move in the direction away from the center of the truncated cone guide block 421. In this process, the second return spring 420 stretches, and the extrusion connecting block 419 drives the push ring 409 to move upward through the oblique pressure rod 410. The piston tube 423 moves downward relative to the guide plug rod 424 as the positioning ring 417 moves downward, so that the third return spring 425 contracts, and at the same time, the aqueous solution inside the piston tube 423 is squeezed into the water tank 414 through the guide plug rod 424, the connecting pipe 418, and the solenoid valve 413. When the flange moves below the extrusion connecting block 419, The end of the extrusion connecting block 419 close to the truncated cone guide block 421 will be restored under the action of the second return spring 420 due to the loss of limit, so that the second return spring 420 limits the top of the flange, and the third return spring 425 applies an upward thrust to the positioning ring 417, so that the top of the truncated cone guide block 421 is fully fitted with the flange at the bottom of the first connecting valve 411. When the limit pin 427 is pulled to separate the limit pin 427 from the positioning hole 428, the second moving contact piece 432 is separated from the second static contact piece 431 as the limit pin 427 moves, so that the solenoid valve 413 is powered off and closed, so that the aqueous solution inside the piston tube 423 loses the flow space, so as to limit the piston tube 423, so that the glass plate liquid level gauge body 412 can be quickly limited and installed, so as to improve the overall detection efficiency of the equipment;

[0054] S3: Open the first connecting valve 411, then pull the limit pin 427 to separate the limit pin 427 from the positioning hole 428. At this time, the piston rod 2 will move toward the liquid storage tank 1 under the action of the elastic restoring force of the pull spring 401, so as to inject the aqueous solution inside the liquid storage tank 1 into the inner side of the glass plate liquid level gauge body 412 through the drain pipe 407 and the connecting cover 408. In this process, the first moving contact piece 429 moves toward the first static contact piece 430 along with the movement of the limit plug rod 403 and the T-shaped pull plate 3. When the aqueous solution fills the glass plate liquid level gauge body 412, the second connecting valve 416 is closed, and the pull spring 401 has not yet fully recovered.

[0055] S4: At this time, the piston rod 2 continuously applies thrust to the aqueous solution inside the liquid storage tank 1, so as to pressurize the aqueous solution inside the glass plate liquid level gauge body 412. After being placed for a period of time, if the sealing performance of the glass plate liquid level gauge body 412 is poor, the aqueous solution inside the liquid storage tank 1 will be pushed by the piston rod 2 and finally discharged from the glass plate liquid level gauge body 412. At this time, the first moving contact piece 429 and the first static contact piece 430 are attached to the buzzer 415, and the buzzer 415 is powered on. Similarly, if the buzzer 415 does not work during the placement process, it means that the sealing performance of the glass plate liquid level gauge body 412 is good. In this way, the sealing performance of the glass plate liquid level gauge body 412 can be clearly and correctly known, the operation is simple, and the labor intensity of the staff is also reduced;

[0056] S5: After the sealing test of the glass plate liquid level gauge body 412 is completed, pull the piston rod 2 so that the limit pin 427 is inserted into the positioning hole 428 again, and at the same time, the aqueous solution fills the liquid storage tank 1. At this time, the second moving contact piece 432 and the second static contact piece 431 contact the water tank 414, and the solenoid valve 413 is energized and opened. Then, the push ring 409 can be pushed upward to make the extrusion connecting block 419 lose the obstruction to the connecting flange on the first connecting valve 411, and then the glass plate liquid level gauge body 412 that has been tested can be removed.

[0057] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
