Description

Technical Field

[0001] This utility model relates to the field of electrical safety equipment technology, and in particular to an automatic shut-off device for electrical equipment. Background Technology

[0002] The widespread use of electrical appliances in daily life and industrial production has brought great convenience to people. However, due to various reasons, such as aging, overload, and short circuit of electrical appliances, safety accidents such as fires and electric shocks may occur, posing a serious threat to people's lives and property. In order to play a protective role, fuses are installed at the circuit wiring points.

[0003] Because fuses have a single protection function, they can only automatically melt in the event of current overload or short circuit, and will not work in the event of voltage overvoltage or undervoltage, which will damage electrical equipment during this period. In view of the above reasons, this application proposes an automatic electrical equipment blocking device. Utility Model Content

Copper plate 2 13 is fixedly connected to conductive plate 6 at the bottom of the first 2. Copper plate 3 14 is fixedly connected to conductive plate 7 at the bottom of the second 3.

[0043] The drive structure 8 includes a PLC 801 for control and a dual-axis motor 803 for drive. Threaded rods 804 are provided on both sides of the dual-axis motor 803. Mounting plates 806 are movably mounted on the threaded rods 804. A battery 802 for power supply is provided below the dual-axis motor 803. A rectangular plate 805 is fixedly provided at the bottom of the mounting plate 806. The rectangular plate 805 and the threaded rods 804 are movably connected. Two sets of sliding grooves are provided on the inner wall of the mounting box 1. Two connecting rods 808 are fixedly provided at the bottom of the two mounting plates 806. The connecting rods 808 and the sliding grooves are movably connected. A conductive plate 807 is fixedly provided on the side of the two mounting plates 806 that is far apart from each other.

[0044] Both the top of the upper terminal block 12 and the upper terminal block 23 are provided with a pressing structure 15. The pressing structure 15 includes a top plate 151 for pressing and a connecting frame 152 for installation. A pull rod 153 is movably provided on the connecting frame 152. A locking block 154 is fixedly provided at one end of the pull rod 153. Two limiting rods 155 are fixedly provided on one side of the locking block 154. The two limiting rods 155 are movably connected to the connecting frame 152. A spring 156 is sleeved on the pull rod 153.

The two insert plates 158 are each provided with a locking block 2 159 on the side that is far apart from each other.

[0045] In this embodiment, upper terminal block 12 and upper terminal block 23 are used to connect the live wire and neutral wire of the circuit. Voltage detection module 10 and current detection module 11 can monitor the current and voltage of the circuit in real time and transmit the data to PLC801. In use, first, the wires at both ends of voltage detection module 10 are passed into upper terminal block 12 and upper terminal block 23 respectively, and the two wires are respectively attached to copper plate 12 and copper plate 314. Then, the two wires of current detection module 11 are passed into upper terminal block 12 and attached to copper plate 12 and copper plate 213 respectively. Then, the two top plates 151 are respectively installed on the top of upper terminal block 12 and upper terminal block 23. Insert plate 158 is inserted into the slot. Insert plate 158 drives the second locking block 159 to move down. The second locking block 159 presses the inclined surface of the first locking block 154. When the inclined surfaces of the two locking blocks separate, spring 156 causes the first locking block 154 to reset and lock above the second locking block 159, realizing the top plate During the installation of module 151, the squeezing block 157 squeezes the wires of voltage detection module 10 and current detection module 11, making them tightly adhere to the copper plate. When it is necessary to remove voltage detection module 10 and current detection module 11, pull each set of pull rods 153 simultaneously in a direction away from each other. When the pull rod 153 causes the first locking block 154 to separate from the second locking block 159, the top plate 151 and the terminal block can be separated. At this time, voltage detection module 10 and current detection module 11 can be removed. After PLC 801 receives the data transmitted by voltage detection module 10 and current detection module 11, it will compare the real-time data with the preset data. If the data is abnormal, PLC 801 will start the dual-axis motor 803. The dual-axis motor 803 will drive two threaded rods 804. The two threaded rods 804 will drive the two mounting plates 806 to move closer together, causing conductive plate 3 807 to separate from the two conductive plates 1 6 and the two conductive plates 2 7, thus achieving the effect of power cut-off.

[0046] The above specific embodiments are merely several optional embodiments of this utility model.
