In practical applications of cryogenic filling and releasing connectors, operators must face harsh working conditions such as extremely low temperatures, high pressures, and flammability and explosiveness. Slight carelessness may lead to risks such as frostbite and explosion.

[0003] Therefore, there is an urgent need for a teaching device for the docking and retraction of cryogenic filling and discharging connectors, so that operators can learn and practice in advance, reducing the possibility of danger during actual operation. Utility Model Content

[0004] The purpose of this invention is to provide a teaching device for docking and dismantling cryogenic filling and discharging connectors.

[0012] In one embodiment, the detection path of the detector coincides with the movement path of the latching member. When the latching member is engaged with the connecting part, the detector is correspondingly positioned with the latching member. When the latching member is separated from the connecting part, the detector is misaligned with the latching member.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The purpose of this invention is to provide a teaching device for docking and retraction of a cryogenic filling and draining connector, in order to solve the problems existing in the prior art. By using a pneumatic module to provide driving force for the pneumatic connector, the simulated connector is connected or disconnected from the simulated filling port, thus simulating the connection process of the cryogenic filling and draining connector.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to Figures 1-2 The low-temperature filling and unloading connector docking and retraction teaching device disclosed in this embodiment of the present invention includes: a simulated connector 1, a simulated filling port 2, a pneumatic module, and a detector 3; wherein, the docking end of the simulated connector 1 is provided with a pneumatic connector, the docking end of the simulated filling port 2 is provided with a connecting part matching the pneumatic connector, the pneumatic module is connected to the pneumatic connector, the pneumatic module is used to provide gas pressure to the pneumatic connector, and the detector 3 is installed on the docking end of the simulated connector 1, the detector 3 is used to detect the connection status between the pneumatic connector and the connecting part; during the simulation operation, the operator manually docks the docking end of the simulated connector 1 with the simulated filling port 2, and uses pneumatic... The module provides gas pressure to the pneumatic connector to drive the pneumatic connector to engage or disengage with the connection part. The detector 3 can monitor the connection status of the pneumatic connector and the connection part according to the status of the pneumatic connector to determine whether the simulated connector 1 and the simulated filling port 2 are properly connected. If they are not properly connected, it indicates that there is improper operation such as misalignment during the operation. At this time, the operator can remove the simulated connector 1 and reconnect it. No cryogenic medium is actually introduced into the simulated connector 1, so there will be no danger during the simulation. It can be used by trainees to operate and observe repeatedly for learning, which can effectively reduce the possibility of danger during the practical operation.

[0030] It is understood that the connection method of the analog connector 1 in the utility model is the same as that of the actual cryogenic injector. This is existing technology and will not be elaborated further here.

[0031] In this embodiment, the connecting part extends radially away from the axis of the simulated filling port 2. The pneumatic connector includes a drive cylinder and a snap-fit ​​component. The drive cylinder is mounted on the simulated connector 1, and the snap-fit ​​component is connected to the drive cylinder. The drive cylinder can drive the snap-fit ​​component to move radially along the simulated filling port 2, so that the snap-fit ​​component can engage or disengage with the connecting part. Its working principle is as follows: when the mating end of the simulated connector 1 is aligned with the mating end of the simulated filling port 2, the snap-fit ​​component is located on the side of the connecting part away from the simulated connector 1. The drive cylinder is controlled by the pneumatic module to work. The drive cylinder drives the snap-fit ​​component to move towards the axis of the simulated filling port 2, so that the snap-fit ​​component can engage with the connecting part, thereby completing the connection between the simulated connector 1 and the simulated filling port 2. The drive cylinder drives the snap-fit ​​component to move away from the simulated filling port 2, so that the snap-fit ​​component can move radially along the simulated filling port 2 to the outside of the connecting part, so as to separate the simulated connector 1 from the simulated filling port 2.

[0032] Preferably, at least two snap-fit ​​components are provided, and the at least two snap-fit ​​components are evenly arranged along the axial direction of the simulated filling port 2. Correspondingly, multiple sets of drive cylinders can be provided.

[0033] In this embodiment, the snap-fit ​​component is a snap-fit ​​block, and the output shaft of the drive cylinder is arranged radially along the simulated filling port 2. The drive cylinder can directly move the snap-fit ​​block closer to or away from the axis of the simulated filling port 2 by contraction.

[0034] In this embodiment, the latching component is a latch, and multiple latches are provided. The hinged end of the latch is rotatably connected to the analog connector 1. The free end of the latch can rotate towards or away from the axis of the analog connector 1. The free end of the latch is provided with a latching protrusion extending towards the axis of the analog connector 1. After the analog connector 1 is connected to the analog filling port 2, the latching protrusion on the latch is located on the side of the connection part away from the analog connector 1, and the latching protrusion along the radial direction of the analog filling port 2 is located on the side of the latching component away from the axis of the analog filling port 2. The drive cylinder can rotate by contraction to realize the connection and separation of the analog connector 1 and the analog filling port 2.

[0035] In this embodiment, the driving cylinder includes a locking cylinder and a releasing cylinder. The locking cylinder is used to drive the snap-fit ​​component to move towards the axis of the simulated filling port 2 to achieve snap-fit ​​between the snap-fit ​​component and the connecting part. The releasing cylinder is used to drive the snap-fit ​​component to move away from the axis of the simulated filling port 2 to achieve separation between the snap-fit ​​component and the connecting part. When the locking cylinder is running, the exhaust port of the releasing cylinder is in the open state, and when the releasing cylinder is running, the exhaust port of the locking cylinder is in the open state to ensure that the device can operate smoothly.

[0036] In this embodiment, the detection path of detector 3 coincides with the movement path of the snap-fit ​​component. When the snap-fit ​​component is snapped into the connecting part, detector 3 and snap-fit ​​component are positioned correspondingly. When the snap-fit ​​component is separated from the connecting part, detector 3 and snap-fit ​​component are misaligned. During the simulation, when the simulation connector 1 and simulation filling port 2 are manually connected, the snap-fit ​​component and connecting part are separated. At this time, the snap-fit ​​component is located on the detection path of detector 3, and detector 3 can detect the snap-fit ​​component. When the drive cylinder drives the snap-fit ​​component to snap into the connecting part, the snap-fit ​​component moves outside the detection path of detector 3. At this time, the operator can judge based on the information emitted by detector 3. The snap-fit ​​component and the connecting part have been successfully snapped together, meaning that the simulated connector 1 and the simulated filling port 2 are successfully connected. If the detector 3 can still detect the snap-fit ​​component after the drive cylinder has run, it means that the snap-fit ​​component has not moved outside the detection path of the detector 3, that is, the snap-fit ​​component has not moved completely into place, and the simulated connector 1 has failed to connect safely to the simulated filling port 2. This indicates that there was improper handling in the operation process, such as starting the drive cylinder before the connection was in place. The operator can optimize the simulation operation and reconnect. Trainees can observe and learn, or they can operate directly, avoiding the dangerous problems that may occur when directly handling the filling and draining connector.

[0037] It is understandable that detector 3 can be an existing sensor such as a photoelectric sensor or an electromagnetic wave sensor, and its specific working principle is existing technology, which will not be elaborated here.

[0038] In this embodiment, the detector 3 includes a green indicator light and a red indicator light. When the detector 3 can detect the snap-fit ​​component, that is, when the snap-fit ​​component is not fully snapped into the connecting part, the green indicator light is lit. When the detector 3 detects the snap-fit ​​component, that is, when the snap-fit ​​component is fully snapped into the connecting part, the red indicator light is lit.

[0041] In this embodiment, the gas distribution platform 5 also includes a first shut-off valve 7 disposed between the gas collecting pipe 6 and the gas cylinder 4, and a second shut-off valve 8 disposed between the gas collecting pipe 6 and the driving cylinder. The first shut-off valve 7 can adjust the on / off state between the gas collecting pipe 6 and the gas cylinder 4, and the second shut-off valve 8 can adjust the on / off state between the gas collecting pipe 6 and the driving cylinder.

[0042] Furthermore, there are two second shut-off valves 8.

Multiple gas cylinders 4 are provided, and the outlets of the multiple gas cylinders 4 are respectively connected to the multiple inlets of the manifold 11. The outlet of the manifold 11 is connected to the inlet of the gas collecting pipe 6.

[0046] Preferably, pressure gauges are installed on the main road and each branch road of the busbar 11, so that the pressure at the busbar 11 can be monitored in real time.

[0047] In this embodiment, the gas in gas cylinder 4 is high-pressure nitrogen.

[0048] In this embodiment, the teaching device for docking and retraction of the cryogenic filling and releasing connector also includes a control module 12, which is connected to the pneumatic module and is used to control the opening and closing state of the pneumatic module.

[0049] In this embodiment, the control module 12 is signal-connected to the first shut-off valve 7, the second shut-off valve 8, and the third shut-off valve 16. The control module 12 can control the opening and closing states of the first shut-off valve 7, the second shut-off valve 8, and the third shut-off valve 16.

[0050] In this embodiment, the teaching device for docking and retraction of the cryogenic filling and releasing connector also includes a monitoring module 13, which is connected to the pneumatic module.

[0051] Furthermore, the monitoring module 13 is connected to the pressure gauge, the first pressure sensor 9, and the second pressure sensor 10, and can monitor the pressure status of each channel in real time through the monitoring module 13.

[0052] In this embodiment, the monitoring module 13 is connected to the detector 3 to monitor the connection status between the card and the connector.

[0053] In this embodiment, the control module 12 and the monitoring module 13 are connected by signals.
