DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0026] Example 1

[0027] A smart meter with leakage protection function, such as Figure 1-8As shown, it includes an electric meter box 1, an insulating shell 2, a sliding door 3, an electric meter head 4, an electrostatic ring 5, an air switch 6, a door opening linkage mechanism and a leakage protection mechanism. The outer surface of the electric meter box 1 is fixedly connected to the insulating shell 2, and two sliding doors 3 are provided. The two sliding doors 3 are respectively slidably connected to the left and right parts of the front side of the electric meter box 1. The connection between the two sliding doors 3 is respectively provided with sealing strips. The material of the sealing strip is rubber. The rubber strip on the right can be inserted into the rubber strip on the left. The two rubber strips cooperate with each other. The electric meter box 1 An electric meter head 4 is fixedly connected to the upper part of the inner surface, and an electrostatic ring 5 is fixedly connected to the circumferential outer surface of the electric meter head 4. The electrostatic ring 5 is made of metal conductive material and is in contact with the outer surface of the electric meter head 4. An air switch 6 is provided below the electric meter head 4. The air switch 6 is fixedly connected to the inner surface of the electric meter box 1. The air switch 6 and the electric meter head 4 are connected by two wires. Two sets of door opening linkage mechanisms are provided, and the two sets of door opening linkage mechanisms are respectively arranged at the upper and lower parts of the inner surface of the electric meter box 1, and the leakage protection mechanism is arranged at the lower part of the inner surface of the electric meter box 1.

[0028] Before using this device, fix it on the wall and connect the lines, then connect the circuit to make the device work normally. During operation, the operator can observe the power consumption displayed on the display screen of the meter head 4 through the glass plate on the sliding door 3. After a long period of use, the internal lines of the meter box 1 are aged and the insulation layer is damaged, which is easy to cause leakage. The electrostatic ring 5 will prevent the meter head 4 from being penetrated by the leakage of the wire. The electrostatic ring 5 has good conductivity. When the aged wire leaks, an arc will be generated. The arc will cause static electricity to be generated inside the device. The rear part of the electrostatic ring 5 is connected to the inner surface of the meter box 1. The static electricity generated inside the device is directly connected to the ground through the ground wire, which releases the static electricity in the device and prevents the meter head 4 from being penetrated by static electricity and damaged. When the operator touches the meter box 1, avoid the human body from being electrocuted. When the wire leaks electricity, the device is powered off through the leakage protection mechanism. When the operator replaces the aging circuit inside the meter box 1, the device is first powered off. The operator pulls the sliding door 3 to the left and right sides. The sliding door 3 will drive the door opening linkage mechanism to keep the leakage protection mechanism away from the wire. At the same time, the air switch 6 is manually closed. The operator replaces the aging wire. After the replacement is completed, the air switch 6 is turned on to re-energize the meter head 4 to make the device work normally. The operator resets the sliding door 3. When the two sliding doors 3 are closed, the cooperation of the two rubber strips prevents humid air and dust from entering the interior of the device, avoiding the fire caused by the device during operation, resulting in loss of life and property. The sliding door 3 drives the door opening linkage mechanism and the leakage protection mechanism to reset.

The upper and lower ends of the three conductive rods 801 are respectively fixed to the two sliding plates 707. The ammeter 802 is fixed to the right side of the lower inner surface of the meter box 1. The rightmost conductive rod 801 is connected to the ammeter 802 by a wire. The ammeter 802 is connected to the meter box. 1 is connected by wires, the current transformer 803 is arranged below the ammeter 802, the current transformer 803 is fixedly connected to the inner surface of the meter box 1, the current transformer 803 and the ammeter 802 are connected by wires, the support block 804 is fixedly connected to the lower part of the inner surface of the meter box 1, the battery 805 is fixedly connected to the right side of the support block 804, the battery 805 and the current transformer 803 are connected by wires, a magnetic induction coil 806 is embedded in the middle of the support block 804, the magnetic induction coil 806 is electrically connected to the battery 805, and a cylindrical iron block 807 is slidably connected to the inner surface of the magnetic induction coil 806, and a total of four groups of wire connection components are provided, and the four groups of wire connection components are respectively fixedly connected to the front side of the support block 804.

[0032] like Figure 6 and Figure 7 As shown, the wire connection assembly includes a support shell 808, a cross screw 809, a rotating block 810, a first conductive block 811, a rotating shaft 812, a torsion spring 813, a second conductive block 814, a connecting shaft 815, a connecting rod 816 and a square plate 817.

[0033] When the wire inside the device ages and leaks electricity, a large number of arcs will be generated, and the arcs will be connected to the conductive rod 801. When the arc is generated, the arc will attract a large number of charged ions to gather at the tip of the metal thorn set on the conductive rod 801. At this time, the arc will discharge the charged ions on the tip of the metal thorn, so that the conductive rod 801 can attract and guide the arc. The conductive rod 801 conducts the current to the ammeter 802 through the wire, and the current changes inside the ammeter 802. At the same time, the arc will be conducted to the meter box 1 along the wire between the ammeter 802 and the meter box 1. The meter box 1 is grounded to ground the arc, and the current transformer 803 monitors the current in the ammeter 802 through the wire. The current transformer 803 controls the battery 805 to continuously supply power to the magnetic induction coil 806.

[0034] When the operator repairs or replaces the circuit of the device, the device is first powered off, and the operator pulls the sliding door 3 to the left and right sides, and the sliding door 3 drives the toothed plate 701 on the same side to slide outward, and the toothed plate 701 drives the first gear 703 to rotate counterclockwise, and the first gear 703 drives the second gear 705 to rotate clockwise, and the second gear 705 drives the rack 709 to move downward, and the rack 709 drives the sliding plate 707 and the support bar 708 to slide downward along the support plate 706, and the sliding plate 707 drives the three conductive Rod 801 moves downward, so that conductive rod 801 moves downward away from the wire to avoid the sharp spikes on conductive rod 801 causing harm to the human body when the operator is changing the line. After opening sliding door 3, air switch 6 is closed to replace the internal aging leakage wire. When the internal wire of this equipment is replaced, the operator turns off the battery 805 to power the magnetic induction coil 806. After the magnetic induction coil 806 is powered off, the cylindrical iron block 807 slides downward, and under the torsion of torsion spring 813, the rotating block 810 is reset.

[0035] After the replacement is completed, the operator powers on the device again, reopens the air switch 6, closes the sliding door 3, and the conductive rod 801 is reset under the drive of the sliding door 3, so that the device continues to work.

Two groups of support assemblies are respectively provided at the lower part of the four wires. The base 901 is fixed to the inner surface of the meter box 1, and the upper end of the base 901 is rotatably connected to the U-shaped plate 902.

[0038] When using the device, the operator pulls the handle 907, and the handle 907 drives the wedge block 906 to slide upward along the fixed rod 904 and squeeze the second spring 905. At this time, the right rear part of the U-shaped plate 902 is provided with a groove which loses the cooperation with the wedge block 906. Under the elastic force of the first spring 903, the right side of the U-shaped plate 902 is bounced up, and the U-shaped plate 902 rotates counterclockwise.
