[0002] The automatic power-off control device is an electronic protection device whose core function is to control the on and off of the circuit. When an abnormal situation in the circuit is detected (such as overvoltage, overcurrent, leakage current or power outage), it can automatically cut off the power supply to protect electrical equipment and personal safety.

[0003] Among them, the device is usually based on the collaborative work of components such as current sensors, electromagnetic triggers, control logic units and execution units. When parameters such as current and voltage in the circuit exceed the preset safety threshold, the current sensor will detect this change and send a signal to the control logic unit.

[0004] When using the existing automatic power-off control device, after the device is installed in the specified position, the current sensor detects the change and sends a signal to the control logic unit.

[0030] See also Figure 1-3 , the utility model provides a technical solution: an automatic power-off control device, comprising a mounting base 1;

[0031] A protective device is provided on the mounting base 1;

[0032] The protective device includes a protective cover 12 and three fixing seats 3. The three fixing seats 3 are fixedly connected to the outer wall of the mounting seat 1. The outer wall of the protective cover 12 is fixedly connected to three fixing frames 4. The three fixing frames 4 are all "L"-shaped. The outer walls of the three fixing seats 3 are provided with fixing frame grooves 5. The outer walls of the three fixing frames 4 at one end away from the protective cover 12 are respectively slidably connected to the inner sides of the corresponding fixing frame grooves 5. The outer walls on both sides of the three fixing seats 3 are fixedly connected to protective shells 7. The outer walls on both sides of the three fixing frames 4 are provided with first limit block grooves 11. The outer walls of the six protective shells 7 are slidably connected with pull rods 6. The inner walls on both sides of the three fixing frame grooves 5 are provided with second limit block grooves 16. The interiors of the second limit block grooves 16 are all slidingly connected to the limit blocks 9, and the outer walls of the ends of the six limit blocks 9 away from the second limit block grooves 16 are respectively in contact with the inner walls of the corresponding first limit block grooves 11. The interiors of the six protective shells 7 are respectively connected to the interiors of the corresponding second limit block grooves 16. The ends of the six pull rods 6 close to the limit blocks 9 are all slidably extended to the interior of the second limit block grooves 16 and are respectively fixedly connected to one end of the corresponding limit blocks 9. The outer wall of the protective cover 12 is slidingly connected to the inside of the groove on the outer wall of the mounting seat 1. The outer walls of the six pull rods 6 are all sleeved with return springs 8, and the two ends of the six return springs 8 are respectively fixedly connected to the inner wall of the corresponding protective shell 7 and one end of the limit block 9.

[0033] Among them, two mounting blocks 2 are installed on the upper and lower outer walls of the mounting base 1, and a power-off controller groove 18 is provided on the outer wall of the mounting base 1. The power-off controller 17 is slidably connected to the inner part of the power-off controller groove 18. The upper and lower outer walls of the power-off controller 17 are fixedly connected to two fixing blocks 13, and the upper and lower inner walls of the power-off controller groove 18 are provided with two fixing block grooves 10. The outer walls of the four fixing blocks 13 are respectively slidably connected to the inner parts of the corresponding fixed block grooves 10. Two fixing bolt grooves 19 are provided on the outer walls on both sides of the mounting base 1. Two fixing plates 14 are fixedly connected to the outer walls of the two fixing plates 14. The outer walls of the two fixing plates 14 are threadedly connected to two fixing bolts 15. The ends of the four fixing bolts 15 close to the fixing bolt grooves 19 are threadedly extended to the outside of the fixing plate 14 and are respectively connected to the internal threads of the corresponding fixing bolt grooves 19. The outer walls of the three interfaces at the lower end of the power-off controller 17 are correspondingly slidably connected to the three opening inner walls at the lower end of the protective cover 12.

[0034] Furthermore, when using the device, it is started by connecting an external power supply, first the mounting base 1 is installed in the designated position through the four mounting blocks 2, and then the three interfaces at the lower end of the power-off controller 17 are connected through the external device. Then, when the current, voltage and other parameters in the circuit exceed the preset safety threshold, the current sensor on the power-off controller 17 will detect this change and send a signal to the control logic unit on the power-off controller 17. Then the control logic unit makes a judgment based on the received signal. When it decides to cut off the power, the relay inside the power-off controller 17 will control the on and off of the power according to the instruction of the control logic. At the same time, when using the protective cover 12 to cover the power off, the relay inside the power-off controller 17 will control the on and off of the power. The electric controller 17 protects the power-off controller 17 to prevent dust from being adsorbed on the surface of the power-off controller 17. Then, when the protective cover 12 needs to be removed, pull the pull rod 6 in the opposite direction to drive the limit block 9 to move in the opposite direction while driving the reset spring 8 to contract. Then, the limit block 9 moves in the opposite direction to disengage the outer wall of its other end from the inside of the first limit block groove 11. Then, pull the protective cover 12 to remove it from the mounting base 1. Then, when the power-off controller 17 needs to be removed, turn the fixing bolt 15 to rotate it so that its other end is disengaged from the inside of the fixing bolt groove 19. Then, pull the power-off controller 17 to remove it from the inside of the power-off controller groove 18.

[0035] The protective cover 12 in the protective device covers the power-off controller 17 to protect the power-off controller 17, thereby preventing dust from being adsorbed on the surface of the power-off controller 17. At the same time, this effectively protects the staff of the shell and prevents the staff from accidentally touching the exposed parts, which may cause electrical accidents such as electric shock or short circuit, thereby improving the practicality and effectiveness of the equipment. By pulling the pull rod 6 in the opposite direction, the limit block 9 is driven to move in the opposite direction and the reset spring 8 is contracted. Then, the limit block 9 is moved in the opposite direction to make the outer wall of the other end disengage from the inside of the first limit block groove 11. Then, the protective cover 12 is pulled to remove it from the mounting base 1, which makes it easy to disassemble the protective cover 12 for cleaning and maintenance, effectively improving the service life of the protective cover 12, thereby improving the flexibility of the equipment.

[0036] Working principle: First, install the mounting base 1 in the designated position through the four mounting blocks 2, then connect the three interfaces at the lower end of the power-off controller 17 through the external device, and then when the current, voltage and other parameters in the circuit exceed the preset safety threshold, the current sensor on the power-off controller 17 will detect this change and send a signal to the control logic unit on the power-off controller 17, and then the control logic unit will make a judgment based on the received signal. When it decides to cut off the power, the relay inside the power-off controller 17 will control the on and off of the power according to the instruction of the control logic. At the same time, when using the protective cover 12 to cover the power-off controller 17, the power-off controller 17 will be connected to the power-off controller 17. The controller 17 is used for protection to prevent dust from being adsorbed on the surface of the power-off controller 17. Then, when the protective cover 12 needs to be removed, the pull rod 6 is pulled in the opposite direction to drive the limit block 9 to move in the opposite direction while driving the reset spring 8 to contract. Then, the limit block 9 is moved in the opposite direction to make the outer wall of the other end disengage from the inside of the first limit block groove 11. Then, the protective cover 12 can be removed from the mounting base 1 by pulling it. Then, when the power-off controller 17 needs to be removed, the fixing bolt 15 is turned to rotate so that the other end is disengaged from the inside of the fixing bolt groove 19. Then, the power-off controller 17 can be removed from the inside of the power-off controller groove 18 by pulling it.
