Description

Technical Field

[0001] This invention relates to the field of safety interlocking technology, and in particular to a quick-opening pressure vessel safety interlocking device. Background Technology

[0002] Pressure vessels are devices used to store and transport gases, liquids, or chemicals. They are designed to withstand high pressures and are commonly used in industrial applications and specific uses. When pressurizing a pressure vessel, it is essential to ensure the vessel lid is closed. If the solenoid valve of the door locking device malfunctions, the lid cannot be closed, rendering the pressure vessel unusable. Summary of the Invention

[0003] Therefore, it is necessary to provide a quick-opening pressure vessel safety interlock device to solve at least one of the aforementioned technical problems.

[0004] A quick-opening pressure vessel safety interlock device includes a support assembly, a pressure tank assembly, a locking assembly, a first locking mechanism, and a second locking mechanism. The support assembly is placed on the ground, the pressure tank assembly is installed on top of the support assembly, and the locking assembly is connected to the pressure tank assembly. The locking assembly has a hollow interior forming a receiving groove. Both the first and second locking mechanisms are installed in the receiving groove, with the second locking mechanism located above the first locking mechanism. The first locking mechanism includes a lifting assembly and a rotating locking assembly. The lifting assembly is slidably installed at the bottom of the receiving groove, and the rotating locking assembly is located above the lifting assembly and passes through the pressure tank assembly and the locking assembly. The second locking mechanism includes a rotating assembly and a thrust locking assembly. The rotating assembly is located above the lifting assembly, and the thrust locking assembly is located above the rotating assembly and slidably passes through the pressure tank assembly and the locking assembly.

[0005] The pressure tank assembly is used to stabilize the pressure of each device. The locking assembly is used to house the first locking mechanism and the second locking mechanism. The lifting assembly of the first locking mechanism can rise under the push of airflow to push the rotating locking assembly to flip, thereby securing the pressure tank assembly. At the same time, when the lifting assembly rises, it will drive the rotating assembly of the second locking mechanism to rotate. While rotating, the rotating assembly will push the protruding locking assembly and insert it into the rotating locking assembly, thus completing the interlock between the first locking mechanism and the second locking mechanism.

[0006] In one embodiment, the support assembly includes three support members, the tops of which are fixedly connected to the bottom of the pressure tank assembly. Each support member includes a support rod and a fixing pad, the top of which is fixedly connected to the bottom of the pressure tank assembly, and the top of which is fixedly connected to the bottom of the support rod.

[0007] In one embodiment, the pressure tank assembly includes a pressure tank, an exhaust pipe, an intake pipe, and a top cover. The pressure tank is mounted on top of three supports, the exhaust pipe is mounted on the side wall of the pressure tank, the intake pipe is mounted on the bottom of the pressure tank, and the top cover is mounted on top of the pressure tank. The side wall of the top cover has a snap-fit ​​groove, and a third valve is also mounted on the intake pipe.

[0008] In one embodiment, the locking assembly includes two fixing rods, a locking body, an air outlet pipe, an air inlet pipe, and a first valve. One end of each of the two fixing rods is inserted into the side wall of the pressure tank. The two side walls of the locking body are respectively fixedly connected to the other ends of the two fixing rods, and the receiving groove is located inside the locking body. One end of the air outlet pipe is inserted into the top of the locking body, and the other end is inserted into the exhaust pipe. One end of the air inlet pipe is fixedly inserted into the bottom of the locking body, and the other end is inserted into the air inlet pipe. The first valve is installed at the bottom of the air inlet pipe.

[0009] In one embodiment, the lifting assembly includes a lifting member and two test pieces. The lifting member is slidably mounted on the bottom of the receiving groove, and the two test pieces are fixedly mounted on both sides of the lifting member.

[0010] In one embodiment, the lifting component includes a lifting body, a spiral cutter, a telescopic rope, a first push rod, a second push rod, and a third push rod. The lifting body is slidably mounted on the bottom of the receiving groove, the spiral cutter is fixedly mounted on the top center position of the lifting body, and the telescopic rope, the first push rod, the second push rod, and the third push rod are all mounted on the top of the lifting body. The length of the first push rod is longer than the length of the second push rod, the length of the second push rod is longer than the length of the third push rod, the first push rod is located on the side adjacent to the telescopic rope, and the second push rod is located between the first push rod and the third push rod.

[0011] In one embodiment, two test pieces are fixedly installed on both sides of the lifting body, and each test piece includes an inverted L-shaped connecting rod, a connecting pipe, and a test tube. The upper end of the connecting rod is fixedly connected to the lifting body, the connecting pipe is sleeved on the lower end of the connecting rod, and a test groove is opened at the top of the connecting pipe. The lower end of the connecting rod is slidably inserted into the test groove, and the upper end of the test tube is inserted into the bottom of the connecting pipe, and the test tube communicates with the test groove. The lower ends of the test tubes of the two test pieces are merged to form a combined pipe, which is inserted into the air inlet pipe. Multiple air leakage ports are opened on the side wall of the combined pipe, and a second valve is installed at the bottom of the combined pipe.

[0012] In one embodiment, the rotating latch assembly includes a rotating rod, a horizontal rod, two locking plates, a Z-shaped latching rod, and a first solenoid valve assembly. The rotating rod passes through the pressure tank and the locking body. The horizontal rod is fixedly installed at one end of the rotating rod adjacent to the lifting body. The two locking plates are fixedly installed in the middle of the rotating rod, and the two locking plates abut against the inner and outer side walls of the pressure tank, respectively. The latching rod is fixedly installed at one end of the rotating rod away from the lifting body. The horizontal rod includes a rising end and a falling end. One side wall of the rising end is fixedly connected to the upper end of the telescopic rope, and the first push rod, the second push rod, and the third push rod are all located below the rising end. The latching rod includes a latching end and a downward end. The latching end is located on the side adjacent to the rising end, and the side wall of the latching end has a fixing groove. The first solenoid valve assembly is electrically connected to the rotating rod.

[0013] In one embodiment, the rotating assembly includes a fixed plate, an annular slide rail, and a rotating plate. The fixed plate and the slide rail are both fixedly installed in a receiving groove, with the slide rail located above the fixed plate. A fan-shaped air outlet is provided on the top of the fixed plate. The rotating plate is rotatably installed in the slide rail, and a venting groove is provided on the top side wall of the rotating plate, extending through the upper and lower surfaces of the rotating plate. A spiral groove is provided at the top center of the rotating plate, and a spiral blade slides through the fixed plate and passes through the spiral groove of the rotating plate.

[0014] In one embodiment, the thrust latch assembly includes a latching post, a latching plate, two springs, and a second solenoid valve assembly. The latching post is slidably inserted into the pressure tank and the latching body. The latching plate is installed in the middle of the latching post. One end of each of the two springs is fixedly connected to the latching plate, and the other end of each spring is fixedly connected to the side wall of the pressure tank. An abutting slope is formed at the end of the latching post adjacent to the rotating plate, and the abutting slope is located in the venting groove. Two flipping latching blocks are installed at the end of the latching post away from the rotating plate. The second solenoid valve assembly is electrically connected to the latching post.

[0015] This invention, by setting up a first solenoid valve assembly and a second solenoid valve assembly, allows the pressure tank to operate smoothly when the top cover is closed and the valve at the air pressure source is opened to allow air to enter through the air inlet pipe. The first solenoid valve assembly drives a rotating rod to rotate, enabling the locking end of the rotating rod to engage with the locking groove of the top cover. When the locking end of the rotating rod is engaged with the locking groove of the top cover, the second solenoid valve assembly is activated, pushing the locking pin towards the fixing groove of the locking end. This causes the two flip-locking blocks to return to their original position and hold against the top cover after disengaging from the fixing groove. This reinforces the fixation between the top cover and the pressure tank, preventing excessive pressure during inflation from causing the top cover to flip and resulting in an accident. By incorporating a first and a second locking mechanism, when the first and second solenoid valve assemblies are damaged and unable to operate, the top cover is closed, the valve at the air pressure source is opened, and air enters through the air inlet pipe. The first valve is opened, and airflow enters through the air inlet pipe, pushing the lifting body upwards. The first push rod rises with the lifting body, pushing the rising end of the horizontal rod. The rising end flips, and the rotating rod also flips with the rising end. The locking end of the locking rod flips and rises with the rotating rod until the rising end abuts against the side wall of the first push rod. The lifting body continues to rise, and the second push rod pushes the rising end of the horizontal rod upwards until it abuts against the side wall of the second push rod. The lifting body continues to rise, and the third push rod pushes the rising end of the horizontal rod upwards until the rising end is locked in the locking groove of the top cover. This prevents excessive pressure during inflation, which could cause the top cover to become unsecured and flip, leading to an accident. Simultaneously, as the lifting body rises, the spiral cutter rises along with it, causing the rotating plate to rotate within the slide rail under the drive of the spiral cutter. When the side wall of the venting groove rotates and abuts against the inclined surface, the side wall of the venting groove pushes against the inclined surface and moves towards the flip-locking blocks. The spring contracts, and the two flip-locking blocks move towards the fixing grooves at the locking ends. This causes the two flip-locking blocks to bend and separate after disengaging from the fixing grooves, abutting against the top cover. This reinforces the fixation between the top cover and the pressure tank, preventing excessive pressure during inflation, which could cause the top cover to flip and cause an accident. This invention has a clever structure that effectively controls the interlocking of the first and second locking mechanisms through airflow control when the first and second solenoid valve assemblies are damaged.

[0040] During installation: The pressure tank assembly 20 is installed on top of the support assembly 10.

The top cover 24 is installed on the top of the pressure tank 21. The first valve 35 is installed at the bottom of the air inlet pipe 34.

Two locking plates 422 are fixedly installed in the middle of the rotating rod 420. The locking rod 423 is fixedly installed at one end of the rotating rod 420 away from the lifting body 412. The fixing plate 510 and the slide rail 511 are both fixedly installed in the receiving groove 31. The rotating plate 512 is rotatably installed in the slide rail 511. The locking plate 521 is installed in the middle of the locking post 520.

[0041] In use: 1. Close the top cover 24. One end of the air inlet pipe 23 is connected to an air pressure source. The valve of the air pressure source, the first solenoid valve assembly, and the second solenoid valve assembly are all electrically connected. Open the valve of the air pressure source to allow air to enter the air inlet pipe 23. The first solenoid valve assembly will drive the rotating rod 420 to rotate, so that the latching end 426 of the rotating rod 420 can be engaged in the latching groove 25 of the top cover 24. When the latching slot 25 is engaged, the second solenoid valve assembly will activate, pushing the latching post 520 towards the fixing slot 428 of the latching end 426. This causes the two flipping locking blocks 524 to bend and flip after disengaging from the fixing slot 428, thus securing them against the top cover 24. This completes the interlocking of the first latching mechanism 40 and the second latching mechanism 50, reinforcing the fixation between the top cover 24 and the pressure tank 21 and preventing excessive pressure during inflation, which could cause the top cover 24 to flip and result in an accident. After the first and second solenoid valve assemblies have been activated, the third valve 26 is opened to inflate the pressure tank 21.

[0042] 2. When the first and second solenoid valve assemblies are damaged and cannot operate, close the top cover 24, open the valve of the air pressure source to allow air to enter through the air inlet pipe 23, open the first valve 35, and the airflow will enter through the air inlet pipe 34, pushing the lifting body 412 upward. The first push rod 415 rises with the lifting body 412, pushing the rising end 424 of the horizontal rod 421. The rising end 424 flips, the rotating rod 420 flips with the rising end 424, and the locking end 426 of the locking rod 423 flips and rises with the rotating rod 420 until the rising end 424 abuts against the side wall of the first push rod 415. The lifting body 412 continues to rise, and the second push rod 416 pushes the rising end 424 of the horizontal rod 421 to continue to flip upward until the rising end 424 abuts against the side wall of the second push rod 416. As the lifting body 412 continues to rise, the third push rod 417 pushes the lifting end 424 of the horizontal rod 421 to continue to flip upward until the lifting end 424 is locked in the buckle groove 25 of the top cover 24, preventing the top cover 24 from being not fixed due to excessive pressure during inflation, which could cause the top cover 24 to flip and cause an accident.

[0043] 3. As the lifting body 412 rises, the spiral cutter 413 will also rise with the lifting body 412, causing the rotating plate 512 to rotate in the slide rail 511 under the drive of the spiral cutter 413. When the side wall of the venting groove 513 rotates and abuts against the abutting slope 523, the side wall of the venting groove 513 will push against the abutting slope 523 and move towards the flip-locking block 524. The spring 522 will contract, and the two flip-locking blocks 524 will move towards the fixing groove 428 of the buckle end 426. This will cause the two flip-locking blocks 524 to bend and separate after disengaging from the fixing groove 428, and hold against the top cover 24 to reinforce the fixation between the top cover 24 and the pressure tank 21, preventing excessive pressure during inflation, which could cause the top cover 24 to flip and cause an accident. Simultaneously, when the lifting body 412 finishes rising, the venting groove 513 of the rotating plate 512 will connect with the vent 515 of the fixed plate 510, allowing the airflow pushing against the lifting body 412 to be discharged into the exhaust pipe 22 through the receiving groove 31, the vent 515, the venting groove 513, and the vent pipe 33. When it is necessary to open the top cover 24, the valve of the air pressure source is closed to release the pressure tank 21 and the locking body 32. The lifting body 412 moves downward, and the rising end 424 of the horizontal rod 421 is held in place in the snap-fit ​​groove 25 of the top cover 24 by the third push rod 417. The spiral cutter 413 moves downward with the rising end 424, driving the rotating plate 512 to rotate back. The spring 522 returns to its original position, causing the abutting inclined surface 523 to return to the venting groove 513, and the two flipping locking blocks 524 close again. The lifting body 412 continues to move downwards, and the lifting end 424 returns to its original position under the pull of the telescopic rope 414.

[0044] 4. Test piece 411 can test the status of the first latching mechanism 40 and the second latching mechanism 50. The top cover 24 is closed, the valve of the air pressure source is opened to allow air to enter through the air inlet pipe 23, and the second valve 434 is opened. The airflow passes through the merging pipe 433 and the two test pipes 432, entering the test chamber. In the test chamber, it pushes the connecting rod 430 upwards, thereby causing the lifting body 412 to rise. After the test, the airflow flows out through multiple leak ports, and the lifting body 412 moves downwards to return to its original position.

[0045] This invention, by setting up a first solenoid valve assembly and a second solenoid valve assembly, allows the top cover 24 to be closed and the valve of the air pressure source to be opened when the pressure tank 21 is in use, allowing air to enter through the air inlet pipe 23. The first solenoid valve assembly drives the rotating rod 420 to rotate, so that the locking end 426 of the rotating rod 420 can be locked in the locking groove 25 of the top cover 24. When the locking end 426 of the rotating rod 420 is locked in the locking groove 25 of the top cover 24, the second solenoid valve assembly is activated, pushing the locking post 520 toward the fixing groove 428 of the locking end 426. This causes the two flipping locking blocks 524 to return to their original position and abut against the top cover 24 after disengaging from the fixing groove 428, thereby reinforcing the fixation between the top cover 24 and the pressure tank 21 and preventing the top cover 24 from flipping due to excessive pressure during inflation, which could cause an accident. By setting the first latching mechanism 40 and the second latching mechanism 50, when the first solenoid valve assembly and the second solenoid valve assembly are damaged and cannot operate, the top cover 24 is closed, the valve of the air pressure source is opened, air enters into the air inlet pipe 23, the first valve 35 is opened, and the airflow enters from the air inlet pipe 34, pushing the lifting body 412 upward. The first push rod 415 rises with the lifting body 412, pushing the rising end 424 of the horizontal rod 421. The rising end 424 flips, the rotating rod 420 flips with the rising end 424, and the latching end 426 of the latching rod 423 flips and rises with the rotating rod 420 until the rising end 424 abuts against the side wall of the first push rod 415. The lifting body 412 continues to rise, and the second push rod 416 pushes the rising end 424 of the horizontal rod 421 to continue to flip upward until the rising end 424 abuts against the side wall of the second push rod 416. As the lifting body 412 continues to rise, the third push rod 417 pushes the lifting end 424 of the horizontal rod 421 to continue to flip upward until the lifting end 424 is locked in the buckle groove 25 of the top cover 24, preventing the top cover 24 from being not fixed due to excessive pressure during inflation, which could cause the top cover 24 to flip and cause an accident. Simultaneously, as the lifting body 412 rises, the spiral cutter 413 rises along with it, causing the rotating plate 512 to rotate in the slide rail 511 under the drive of the spiral cutter 413. When the side wall of the venting groove 513 rotates and abuts against the abutting inclined surface 523, the side wall of the venting groove 513 will push against the abutting inclined surface 523 and move towards the flip-locking block 524. The spring 522 contracts, and the two flip-locking blocks 524 move towards the fixing groove 428 of the latching end 426. This causes the two flip-locking blocks 524 to bend and separate after disengaging from the fixing groove 428, and abut against the top cover 24 to reinforce the fixation between the top cover 24 and the pressure tank 21, preventing excessive pressure during inflation, which could cause the top cover 24 to flip and cause an accident. The invention has an ingenious structure that can effectively control the interlocking of the first latching mechanism 40 and the second latching mechanism 50 through airflow control when the first solenoid valve assembly and the second solenoid valve assembly are damaged.
