Description

Technical Field

[0001] This invention belongs to the technical field of pressure vessel simulation and practical assessment, and relates to a detachable pressure vessel simulation and practical assessment device based on logic switches. Background Technology

[0002] The State Administration for Market Regulation issued the "Special Equipment Operator Assessment Rules (TSG Z6001-2019)," requiring pressure vessel operators to obtain a special equipment operator certificate through a passing assessment before they can perform related work. Currently, most pressure vessel operator training and assessment institutions rely solely on theoretical teaching from textbooks, primarily using traditional methods such as training outlines, classroom instruction, and written examinations. They lack a simulation system tailored to the specific equipment, failing to vividly and intuitively simulate the real-world operating environment of the equipment. They cannot simulate equipment malfunctions or provide practical skills training and assessment on troubleshooting, handling common accidents, energy conservation, and emission reduction. Consequently, operators cannot achieve proficiency in pressure vessel operation techniques and skills through hands-on training.

[0003] Currently, teaching on pressure vessels is generally limited to books and the internet, and sometimes involves on-site visits to enterprises to learn through actual equipment. However, since pressure vessels at these sites are typically large and the environment is complex, it is not conducive to learning and operation. Therefore, some smaller pressure vessels have been created for simulation teaching and assessment purposes. However, the pressure vessels used for simulation assessment can also perform functions such as pressurization, cooling, and evaporation, and are equipped with the same pressure gauges, thermometers, pressure reducing valves, and various pipelines. Because the entire pressure vessel adopts the same integrated structure as the actual one, it cannot be disassembled in many ways, which brings certain difficulties to the maintenance and replacement of components and to teaching. It also has poor flexibility in use. Therefore, we propose a detachable pressure vessel simulation and practical assessment device based on logic switches to solve the above-mentioned problems. Summary of the Invention

[0004] In view of this, in order to solve the problem that traditional pressure vessels used for simulated practical assessment also adopt the same integrated structure as the actual ones, which cannot be disassembled in many ways, causing certain troubles for component maintenance and replacement and teaching, and resulting in poor flexibility in use, the present invention provides a detachable pressure vessel simulation practical assessment device based on logic switches.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a base, and further comprising:

[0006] Two first cylinders are symmetrically arranged on the base. The outer walls of the two first cylinders at their far ends are sealed with collars. The two collars at their far ends are fixedly connected with mounting rings. The two mounting rings at their far ends are hinged with vessel doors to seal one end of the first cylinder. Gas pipes are fixedly inserted through the bottom of the two first cylinders at their far ends. One end of the two gas pipes is connected to the same pressurization pipeline through a flange. The bottom edges of the two collars at their near ends are provided with notches to accommodate the gas pipes.

[0007] The second tank is connected between the two first tanks and docks with the two first tanks to form a complete pressure vessel. The second tank is equipped with pressure gauges, thermometers, safety valves and various pipelines.

[0011] Furthermore, the base includes two supporting bottom bars supported on the ground, and two reinforcing cross bars are symmetrically fixedly connected between the tops of the two supporting bottom bars. The tops of the two reinforcing cross bars are each fixedly connected with a symmetrically arranged U-shaped plate, and the tops of the two U-shaped plates are each fixedly connected with a support seat. The two first canisters are respectively supported and placed on the two support seats.

[0012] Furthermore, the adjustment mechanism includes an adjusting screw that rotates through one side of the U-shaped plate. A nut plate is threaded onto the outer wall of the adjusting screw. Four connecting rods are symmetrically fixedly connected in pairs on one side of the nut plate. One end of two connecting rods on the same side is fixedly connected to the same support rod, and the top ends of the two support rods are fixedly connected to the bottom outer wall of the corresponding collar. A handle is fixedly connected to one end of the adjusting screw. A sliding rod is embedded in the end of the adjusting screw away from the handle. One end of the sliding rod extends outward and is fixedly connected to a connecting plate, which is fixedly connected between the two support rods. A limiting ring is fixedly sleeved on the outer wall of the end of the adjusting screw away from the handle.

[0013] Furthermore, each of the four support rods has a movable support plate fixedly connected to its bottom end. The movable support plate is slidably connected to the top of the support base bar and passes through the corresponding reinforcing crossbar. Each of the two support base bars has two grooves symmetrically opened at its bottom. Each of the four grooves has an L-shaped sliding plate slidably connected to its top wall. One end of each of the four L-shaped sliding plates extends outward and is fixedly connected to one side of the bottom of the corresponding four movable support plates. Each of the four L-shaped sliding plates has two rollers symmetrically connected to its bottom. Each of the four grooves has a pad fixedly connected to the side of the opening edge, and the top of the pad is in contact with the bottom support of the L-shaped sliding plate.

[0014] Furthermore, two actuating rings are symmetrically fixedly connected to both sides of the outer wall of the second can. Each actuating ring has four first connecting screw holes equidistantly arranged in a ring on one side. Two second fixing blocks are symmetrically fixedly connected to the outer walls of the two first cans. One side of the second fixing block is in contact with one side of the actuating ring. A first connecting screw is threaded through one side of the second fixing block, and the first connecting screw is threadedly connected to the corresponding first connecting screw hole. A handle is fixedly connected to the end of the first connecting screw away from the actuating ring.

[0015] Furthermore, each of the two actuating rings has multiple gripping holes arranged in a ring shape on one side.

[0016] Furthermore, a second connecting screw is fixedly connected to the end of the handle away from the first connecting screw, and two first fixing blocks are symmetrically fixedly connected to the side of the two collars that are close to each other. The side of the first fixing block away from the collar has a second connecting screw hole that is threadedly connected to the second connecting screw. A guide block is sleeved on the outer wall of the second connecting screw, and the guide block is fixedly connected to the outer wall of the first tank.

[0017] Furthermore, the bottom outer walls of the two first tank cylinders are fixedly connected with base plates, and the sides of the two base plates that are close to each other are in contact with the sides of the two support seats that are far apart from each other. The sides of the two base plates that are close to each other are symmetrically fixedly connected with two positioning screws. The sides of the two support seats are symmetrically opened with two positioning holes that are in contact with the positioning screws. One end of each of the multiple positioning screws is threaded with a locking nut that abuts against the side of the corresponding support seat.

[0018] The beneficial effects of this invention are as follows:

[0019] This invention connects the vessel door to the first cylinder and the first cylinder to the second cylinder using a snap-fit ​​connection, allowing for multi-faceted assembly and disassembly of the entire pressure vessel. Furthermore, by centralizing all components on the second cylinder and adjusting its rotation, the entire pressure vessel can be subjected to targeted maintenance, replacement, and simulation training, thus improving its overall flexibility. The vessel door can be moved outward by rotating the handle, enabling assembly and disassembly of the first and second cylinders. This simple operation enhances the practicality of the entire pressure vessel.

[0039] Example 1

[0040] like Figures 1-10 As shown, the detachable pressure vessel simulation and practical assessment equipment based on logic switches includes a base on which two first tanks 1 are symmetrically arranged. The outer walls of the two first tanks 1, which are far apart from each other, are sealed with collars 4. The two collars 4, which are far apart from each other, are fixedly connected to mounting rings 6. The two mounting rings 6, which are far apart from each other, are hinged to valve doors 7 for sealing one end of the first tank 1. The bottom of the two first tanks 1, which are far apart from each other, are fixedly connected to air pipes 11. One end of the two air pipes 11 is connected to the same pressurization pipeline 19 through a flange. The bottom of the two collars 4, which are close to each other, are provided with notches 13 to accommodate the air pipes 11. The two first tanks 1 are connected to the same second tank 3, which is connected to the two first tanks 1 to form a complete pressure vessel. The second tank 3 is equipped with a pressure gauge, a thermometer, a safety valve, and various pipelines.

[0041] In one aspect of this embodiment, such as Figure 5 , Figure 9 As shown, a first retaining ring 15 is fixedly connected to the end of the first tank 1 away from the second tank 3. A first annular groove 14 located inside the collar 4 is opened on the side of the mounting ring 6 near the first tank 1, and the first annular groove 14 is adapted to engage with the first retaining ring 15. A first sealing ring 18 is fixedly connected to the side of the first retaining ring 15 away from the first tank 1, which seals against the inner wall of the first annular groove 14. When connecting the vessel door 7 to the first tank 1, the collar 4 is first fitted onto the outer wall of the first tank 1 and slid inward, allowing the gas pipe 11 to be moved aside through the notch 13, and the first retaining ring 15 is engaged in the first annular groove 14. At the same time, the sealing contact between the first sealing ring 18 and the first annular groove 14 achieves a sealing engagement between the first tank 1 and the mounting ring 6. In normal use, when it is necessary to open the pressure vessel, only the vessel door 7 needs to be opened.

[0042] In one aspect of this embodiment, such as Figures 6-10 As shown, a connecting ring 24 is fixedly connected to one end of the first can 1 near the second can 3. A second annular groove 25 is provided on one side of the connecting ring 24. Two fixing rings 26 are symmetrically fixedly connected to the inner wall of the second can 3. A second retaining ring 27 that is adapted to and engages with the corresponding second annular groove 25 is fixedly connected to the side of the two fixing rings 26 that is far away from each other. A second sealing ring 28 that seals against the inner wall of the second annular groove 25 is fixedly connected to the side of the second retaining ring 27 that is far away from the fixing ring 26. When connecting the first tank 1 and the second tank 3, the connecting ring 24 is first inserted into one end of the second tank 3, and the second retaining ring 27 is engaged in the second annular groove 25. At the same time, the sealing contact between the second sealing ring 28 and the second annular groove 25 achieves a sealing engagement between the first tank 1 and the second tank 3, thus completing the assembly of the pressure vessel. Conversely, since pressure gauges, thermometers, safety valves, and various pipelines are all concentrated on the second tank 3, disassembling the second tank 3 facilitates the maintenance and replacement of components. Furthermore, the detachable connection between the vessel door 7, the first tank 1, and the second tank 3 allows for the maintenance and replacement of corresponding parts without the need to transport or replace the entire equipment, reducing the hassle of subsequent maintenance and replacement. Moreover, the detachable pressure vessel enhances the teaching effect during simulation sessions.

[0043] In one aspect of this embodiment, such as Figure 3As shown, the base includes two supporting base bars 2 supported on the ground. Two reinforcing crossbars 35 are symmetrically fixedly connected between the tops of the two supporting base bars 2. U-shaped plates 36, arranged symmetrically, are fixedly connected to the tops of each of the two reinforcing crossbars 35. Support seats 12 are fixedly connected to the tops of each of the two U-shaped plates 36, and the two first tank cylinders 1 are respectively supported and placed on the two support seats 12. The two support seats 12 can support and place the two first tank cylinders 1 respectively, and thus the entire base can support the entire pressure vessel.

[0044] This application can be used in the field of pressure vessel simulation and practical assessment, and can also be applied to other fields.

[0045] Example 2

[0046] This embodiment is a further improvement on the previous embodiment: such as Figures 7-9 As shown, the pressure vessel simulation and practical assessment equipment also includes two sets of adjustment mechanisms symmetrically arranged on the base, used to control the support movement of the two vessel doors 7 respectively, facilitating the disassembly and assembly of the entire pressure vessel. The adjustment mechanism includes an adjustment screw 37 that rotates through one side of the U-shaped plate 36. A nut plate 38 is threaded on the outer wall of the adjustment screw 37. Four connecting rods 39 are symmetrically fixedly connected to one side of the nut plate 38. One end of two connecting rods 39 on the same side is fixedly connected to the same support rod 5, and the top ends of the two support rods 5 are fixedly connected to the bottom outer wall of the corresponding collar 4. A handle 41 is fixedly connected to one end of the adjustment screw 37. A sliding rod 43 is embedded in the end of the adjustment screw 37 away from the handle 41. One end of the sliding rod 43 extends outward and is fixedly connected to a connecting plate 42, and the connecting plate 42 is fixedly connected between the two support rods 5. A limiting ring 40 is fixedly sleeved on the outer wall of the end of the adjustment screw 37 away from the handle 41. When it is necessary to move the vessel door 7 outward, rotating the handle 41 drives the adjusting screw 37 to rotate, which in turn moves the nut plate 38. Simultaneously, the four connecting rods 39 push the two support rods 5 outward, thereby causing the collar 4 to slide outward. Figure 11 As shown, the collar 4 drives the vessel door 7 to move through the mounting ring 6, thereby moving the vessel door 7 outward away from the first tank 1 and separating the vessel door 7 from the first tank 1. At this time, the first tank 1 can also be moved outward and removed, realizing the disassembly of the pressure vessel. During the movement of the support rod 5, the connecting plate 42 can be moved synchronously, and the sliding rod 43 can be extended outward within the adjusting screw 37, so that the adjusting screw 37 is always fitted on the sliding rod 43, thereby increasing the stability of the rotation of the adjusting screw 37.

[0047] In one aspect of this embodiment, such as Figures 7-9As shown, each of the four support rods 5 has a movable support plate 44 fixedly connected to its bottom end. The movable support plate 44 is slidably connected to the top of the support base bar 2 and passes through the corresponding reinforcing crossbar 35. Each of the two support base bars 2 has two symmetrically formed grooves 46 at its bottom. Each of the four grooves 46 has an L-shaped slide plate 45 slidably connected to its top wall. One end of each of the four L-shaped slide plates 45 extends outward and is fixedly connected to one side of the bottom of the corresponding four movable support plates 44. Each of the four L-shaped slide plates 45 has two symmetrically connected rollers 47 at its bottom. Each of the four grooves 46 has a pad 17 fixedly connected to the side of the opening edge, and the top of the pad 17 is in contact with the bottom support of the L-shaped slide plate 45. When the rotating handle 41 moves the collar 4 outward via the support rod 5, it also moves the movable support plate 44 outward simultaneously. The movable support plate 44 can support and fix the support rod 5, thereby improving the stability of the movement and installation of the vessel door 7. At the same time, the movable support plate 44 drives the L-shaped sliding plate 45 to extend and slide outward. Through the rolling of the roller 47, not only can the stable support of the vessel door 7 be improved, but also the smoothness of the movement process can be improved. The support of the L-shaped sliding plate 45 by the pad block 17 can further improve the stability of the entire movement process.

[0048] Example 3

[0049] This embodiment is a further improvement on the previous embodiment: such as Figures 4-10 As shown, two actuating rings 9 are symmetrically fixedly connected to both sides of the outer wall of the second can 3. Four first connecting screw holes 10 are equidistantly opened on one side of each actuating ring 9. Two second fixing blocks 30 are symmetrically fixedly connected to the outer walls of the two first cans 1. One side of the second fixing block 30 is in contact with one side of the actuating ring 9. A first connecting screw 31 is threaded through one side of the second fixing block 30, and the first connecting screw 31 is threadedly connected to the corresponding first connecting screw hole 10. A handle 32 is fixedly connected to the end of the first connecting screw 31 away from the actuating ring 9. After the first can 1 and the second can 3 are connected, the second can 3 can rotate between the two first can 1, which makes it easy to rotate the components on the second can 3 to a horizontal position and reduce its height. This facilitates both simulation and explanation, as well as maintenance and replacement. In order to strengthen the stable connection between the first can 1 and the second can 3, the lever 32 can be rotated to drive the first connecting screw 31 to rotate, thereby making it threadedly connected to the first connecting screw hole 10 on the actuating ring 9. Since four corresponding first connecting screw holes 10 are provided, two of them can be selected for connection according to the rotation requirements of the second can 3, thus ensuring the connection stability between the second can 3 and the first can 1.

[0050] In one aspect of this embodiment, such as Figure 10As shown, each of the two actuating rings 9 has multiple grip holes 29 arranged in a ring shape on one side. The grip holes 29 facilitate the hand's grip on the actuating ring 9, thereby facilitating the rotation and adjustment of the second canister 3, making operation convenient.

[0051] Example 4

[0052] This embodiment is a further improvement on the previous embodiment: such as Figures 7-9 As shown, the end of the handle 32 away from the first connecting screw 31 is fixedly connected to the second connecting screw 33. Two first fixing blocks 8 are symmetrically fixedly connected to the sides of the two collars 4 that are close to each other. The side of the first fixing block 8 away from the collar 4 is provided with a second connecting screw hole 16 that is threadedly connected to the second connecting screw 33. The outer wall of the second connecting screw 33 is fitted with a guide block 34, and the guide block 34 is fixedly connected to the outer wall of the first tank cylinder 1. When rotating the lever 32 drives the first connecting screw 31 to rotate, when the first connecting screw 31 is threadedly connected to the first connecting screw hole 10 on the actuating ring 9, the second connecting screw 33 is not connected to the second connecting screw hole 16 on the first fixing block 8; when the first connecting screw 31 is not threadedly connected to the first connecting screw hole 10 on the actuating ring 9, the second connecting screw 33 is threadedly connected to the second connecting screw hole 16 on the first fixing block 8. This alternation allows the first canister 1 to be reciprocated between the second canister 3 and the collar 4. When it is necessary to simultaneously remove the vessel door 7 and the first canister 1, such as... Figure 12 As shown, by rotating the handle 41, the vessel door 7 is moved. At this time, through the connection between the second connecting screw 33 and the first fixing block 8, the first can cylinder 1 can be moved synchronously through the collar 4, so that the first can cylinder 1 is away from the second can cylinder 3. Then, by contacting the connection between the first can cylinder 1 and the second can cylinder 3 on the other side in the same way, the second can cylinder 3 can be disassembled.

[0053] Example 5

[0054] This embodiment is a further improvement on the previous embodiment: such as Figure 6 , Figure 8As shown, both bottom outer walls of the first cans 1 are fixedly connected to base plates 20, and the sides of the two base plates 20 that are close to each other are in contact with the sides of the two support seats 12 that are far apart from each other. Two positioning screws 22 are symmetrically fixedly connected to the sides of the two base plates 20 that are close to each other. Two positioning holes 21 are symmetrically opened on one side of each of the two support seats 12, which are through-holes of the positioning screws 22. One end of each of the positioning screws 22 is threaded with a locking nut 23 that abuts against the corresponding side of the support seat 12. When the first cans 1 are overlapped and placed on the support seats 12, during the docking process with the second cans 3, the orientation of the first cans 1 can be adjusted first, so that the positioning screws 22 pass through the positioning holes 21 for positioning. This allows for the positioning of the handle 32, facilitating the fixed connection between the first cans 1 and the second cans 3 by rotating the handle 32 after the first cans 1 and the second cans 3 are positioned and snapped together. Simultaneously, the connection between the support seats 12 and the base plates 20 also improves the stability of the support connection of the first cans 1.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
