[0041] The following is combined with Figures 1 to 5 This application is described in further detail.

[0042] The embodiment of the present application discloses a remote quick disconnect device.

[0043] Reference Figures 1 to 5 , a remote quick disconnect device, comprising:

[0044] The socket assembly includes a socket housing 1, a socket unit 2 is arranged at one end of the socket housing 1, and an ejector rod 3 is arranged inside the socket housing 1. The ejector rod 3 is driven by the power assembly to move along the two ends of the socket housing 1, and one end of the ejector rod 3 penetrates the socket unit 2. There are four ejector rods 3, which penetrate the four corners close to the socket unit 2 respectively, and the other ends of the four ejector rods 3 are fixed to the ejector plate 4. There are four ejector rods 3, and the ejector plate 4 drives multiple ejector rods 3 to move at the same time, so that the driving force on the plug unit 13 is evenly distributed, ensuring that the plug unit 13 is quickly and stably separated from the socket unit 2.

[0045] The power assembly includes a cylinder 5, which is installed in the socket housing 1 through a cylinder 5 bracket. The end of the telescopic rod of the cylinder 5 is connected to the ejector plate 4, which drives the ejector plate 4 to move along the two ends of the socket housing 1. The ejector rod 3 is driven by the cylinder 5 to move, and then the plug unit 13 is pushed out from the socket unit 2 to achieve the disconnection operation. It is driven by the cylinder 5, which is easy to control, simple to operate, and quick to respond.

[0046] A pneumatic two-piece pressure switch is installed on the socket housing to detect the pressure in the gas circuit and output a feedback signal when the gas pressure is abnormal.

[0047] The power assembly also includes a manual push rod 6, which is arranged on the side of the ejector plate 4 in the socket housing 1 away from the ejector rod 3. The bottom end of the manual push rod 6 is hinged to the socket housing 1, and the manual push rod 6 and the ejector plate 4 are hinged through a connecting rod. Through the setting of the manual push rod 6, the operator can push and pull the manual push rod 6 to drive the ejector plate 4 to move, and then push the plug unit 13 to separate from the socket unit 2 to achieve the disconnection operation. The manual push rod 6 can be directly operated by the operator, and the manual operation is more stable and reliable, and can be operated in an emergency under the condition of power failure and gas failure. A manual handle 7 (with an insulating sleeve) is arranged on the top of the manual push rod 6, and the manual handle 7 passes through the top of the socket housing 1 and is provided with a strip notch 8. Through the setting of the manual handle 7, the socket housing 1 is passed through the strip notch 8 on the top of the socket housing 1, so that the socket housing 1 forms a certain protection for the internal structure, and also prevents the operator from accidentally touching it, which plays a protective role. The top of the socket housing 1 is provided with a cover plate 9, which is convenient for opening and closing, and the strip notch 8 is provided on the cover plate 9.

[0048] A cover plate detection switch is installed in the socket housing 1, which is a sensor switch for detecting whether the cover plate 9 is opened or closed. When the cover plate 9 is opened, a feedback signal is output.

[0049] A push rod position switch for detecting the manual push rod 6 is installed on the socket housing 1. Through the setting of the push rod position switch, the position of the manual push rod 6, that is, the state detection of the manual push rod 6, can be detected, and whether the manual push rod 6 is in the starting position, that is, the manual push rod 6 is in a state position away from the plug assembly. When the manual push rod 6 is not detected, that is, the manual push rod 6 is not in the starting position, a feedback signal is output.

[0050] Photoelectric switches 10 are installed on the socket housings 1 on both sides of the socket unit 2. Through the setting of the photoelectric switches 10, the presence or absence of the plug unit 13 on the socket unit 2 can be detected, that is, the plug-in matching and disconnection detection of the plug unit 13 and the socket unit 2 can be detected.

[0051] A bottom tray 11 is provided on the socket housing 1 at the bottom of the socket unit 2. The bottom tray 11 can support the plug assembly from the bottom to prevent the plug assembly from falling and bumping after the plug unit 13 is disconnected from the socket unit 2.

[0052] The plug assembly includes a plug housing 12, a plug unit 13 that cooperates with the socket unit 2 is arranged at the other end of the plug housing 12, close to one end of the socket unit 2; a guide hole 14 is arranged on the socket unit 2, and a guide pin 15 that cooperates with the guide hole 14 is arranged on the plug unit 13.

[0053] The socket unit 2 is provided with a current jack 16, the plug unit 13 is provided with a current pin 17, the socket unit 2 is provided with a signal end jack module 18, and the plug unit 13 is provided with a signal end pin module 19. The cooperation between the plug assembly and the socket assembly, that is, when the plug unit 13 is inserted into the socket unit 2, the current pin 17 is docked with the current jack 16, the signal end pin module 19 is docked with the signal end jack module 18, and the length of the signal end pin module 19 is shorter than the current pin 17. In the process of disconnecting the plug unit 13 from the socket unit 2, the signal disconnect pin is first disconnected from the signal end jack module 18, and the disconnection signal controls the switches of the linkage device and the input power supply of the battery pack, so that the input power supply of the battery pack is disconnected first, that is, the current pin 17 is in a non-charged state, and then the current pin 17 is disconnected from the current jack 16, so as to realize the separation of the plug assembly and the socket assembly, and the separation is performed after the power is cut off first, and no arc is generated, which is also safer.

[0054] A locking mechanism is provided between the socket assembly and the plug assembly, and the locking mechanism includes a locking socket 20 on the socket unit 2 and a locking plug 21 on the plug unit 13. Through the setting of the locking mechanism, the plug unit 13 will be locked after being inserted into the socket unit 2, so as to prevent the plug unit 13 from being accidentally dragged or automatically dropped, etc., and being separated from the socket unit 2.

[0055] A handle 22 is provided on the plug housing 12 . The handle 22 facilitates the matching of the plug assembly and the socket assembly, that is, the operation of inserting the plug unit 13 into the socket unit 2 .

[0056] Through the guiding effect of the guide socket 14 and the guide pin 15, the plug unit 13 can be accurately inserted into the plug assembly to complete the docking. Driven by the power assembly, the plug unit 13 is pushed out by pushing the ejector rod 3, and the plug unit 13 is disengaged from the socket unit 2, thereby realizing the separation of the plug assembly and the socket assembly. When the current needs to be cut off, the current can be quickly disconnected, the battery pack can be separated, and the current can be quickly cut off to ensure the safety of the test.

[0057] The disconnecting device also includes a control component, which includes: a control box 23, an emergency stop button, and an indicator light. It is used to execute the disconnection action through the emergency stop switch, and confirm the start of the disconnection procedure and the completion of the disconnection through the feedback indicator light. There is a protective cover on the emergency stop button to prevent accidental contact. The button indicator light is used to turn the device on and off, and the indicator light on the button shows the operating status of the device. There are signs at the button and indicator light to indicate the purpose.

[0058] When the battery pack is abnormal, by pressing the emergency stop button, the cylinder 5 is controlled to operate and push the ejector plate 4, so that the plug assembly and the socket assembly are disconnected, and the battery pack is separated and disconnected.

[0059] After the emergency stop button is pressed, a switch signal will be given to the charging and discharging equipment and the water cooler (cooling) (this signal is a stop command for the linkage equipment, and the signal command can be increased according to the number and type of equipment). After a delay of 0.5S, the cylinder pressure begins to push the plug unit 13 and the socket unit 2 to disconnect (the delay time is to ensure that other linkage equipment stops working, and the delay time can be adjusted according to the shutdown time of the current output equipment and the water cooler). When the plug unit 13 is disconnected from the socket unit 2, the signal end pin module 19 and the signal end jack module 18 are disconnected first. The signal end controls the switch for the linkage equipment and the battery pack input power supply (here, ensure that the non-powered disconnection is ensured, and the air pump valve can be used to adjust the disconnection time). After the signal end pin module 19 and the signal end jack module 18 are disconnected first, the current pin 17 and the current jack 16 are disconnected again, and the disconnection is completed. The whole process takes about 2 seconds.

[0060] This application has a series of protection signals to ensure the reliability of the device:

[0061] Emergency stop button signal, normally closed signal, after pressing the emergency stop button, feedback is sent to the host computer system and coolant control terminal;

[0062] Two-piece pressure switch signal, normally closed signal, when the pressure is lower than the set minimum value or higher than the set maximum value, an abnormality is detected and fed back to the host computer system to alarm;

[0063] The cover plate detects the switch signal, which is a normally closed signal. When the cover plate 9 is opened, a feedback signal is output and fed back to the system end to alarm;

[0064] The push rod position switch initial position signal is a normally closed signal. When the manual push rod 6 is not in the initial position, it means that the plug unit 13 is not fully inserted into the socket unit 2. At this time, the feedback signal is sent to the host computer system to alarm.

[0065] The photoelectric switch signal is a normally closed signal. When the plug assembly and the socket assembly are separated successfully, the photoelectric switch signal is fed back to the host computer system, indicating that the separation action is completely completed.

[0066] Advantages of this application:

[0067] 1. Safe and reliable. When the battery fails, the output current can be cut off quickly, and the fastest disconnection can be achieved in milliseconds.

[0068] 2. The disconnecting device is relatively small as a whole, easy to install and construct.

[0069] 3. Compared with similar products, the cost is lower and the device is designed to have a long life.

[0070] 4. Normally cutting off the current output will cause arcing. This device delays cutting off after the stop signal is sent and stops the output of peripheral equipment such as charging and discharging equipment during the cutting process, which greatly improves the safety of output cutting off and the safety of peripheral linkage equipment.
