[Introduction of New Patent] An anti-theft and anti-moisture meter

Today I will introduce to you a national invention authorized patent-an anti-theft and anti-moisture meter. The patent was applied by Jiangsu Liyang Electronic Instrument Co., Ltd. and was authorized to be announced on March 27, 2018.

The invention relates to the technical field of electric meters, in particular to an anti-theft and anti-moisture electric meter.

Electricity meters need to be installed in public places such as municipalities, communities, electric power, rural power grids, factories, etc., which also requires electricity meter boxes. However, the current meter box of the existing discharge meter usually uses transparent materials such as glass and plastic to make the observation window, and criminals can break it up to steal and steal electricity, which will bring losses to the public interest. In addition, after the long-term use of the traditional meter box, water and moisture easily flow into the meter from the junction of the box body and the lid of the meter box. In this way, the meter is susceptible to moisture and conducts electricity. There is a great potential safety hazard and a short service life.

The purpose of the present invention is to provide an anti-theft and anti-moisture electricity meter, which avoids the hidden dangers of electricity safety and electricity theft caused by the exposure of the electricity meter wiring.

The figure is a schematic diagram of the present invention.

In order to solve the above technical problems, the technical solutions adopted by the present invention are: an anti-theft and moisture-proof electric meter, including an electric meter box and a box cover; a transparent glass window is provided on the box cover; and an electric meter box is also provided for blocking the box cover The protective device of the transparent glass window; the protective device includes the lateral movement locking buckle plate, the cover plate, the traction electromagnet and the return spring; the meter box is provided with a horizontal plate on the lower side of the cover; the cover plate is hingedly connected to the horizontal plate; the meter box The body is provided with fixing plates on both sides of the box cover; a cavity is provided on the top of the fixing plate; a strip hole is provided on the outer side of the cavity; a horizontally moving plate with a rectangular socket in the middle of the horizontally moving locking plate; a horizontally moving plate The two ends are connected to a moving block through a connecting plate; the moving block is connected to the top of the cavity through a return spring; the bottom of the cavity is provided with a traction electromagnet, and the traction electromagnet is electrically controlled to move the moving block downward; the traction electromagnet loses power The mobile block moves upward; the traction electromagnet is connected to the controller; the controller is connected to the mobile control terminal through a wireless transceiver; the meter box is also provided with a moisture-proof component.

The middle part of the fixing plate is provided with a limit stopper which restricts the rotation position of the shielding baffle; the middle part of the limit stopper is provided with a slot; the pins on the both sides of the shielding baffle are inserted into the slot; the slot is provided with a spring leaf A; the end of the pin is provided with a spring B. The moisture-proof component includes a fan, a humidity sensor, a processor and a microcontroller that are arranged inside the meter box; the fan is arranged on the upper wall of the meter box; the upper part of the meter box is provided with a first cooling hole; the lower part of the meter box is provided There is a second heat dissipation hole; the humidity sensor is used to detect the humidity in the meter box; the humidity sensor is connected with the processor; the processor is connected with the microcontroller, and the microcontroller controls the fan to rotate. The inner wall of the meter box is also provided with a moisture-proof and moisture-absorbing board. An anti-theft alarm component is also installed in the meter box; the anti-theft alarm component current and voltage detection module, drive module, charge and discharge control module, metering module, processing module, alarm module and communication module; the current and voltage detection module is connected to the metering module; the metering module is The processing module is connected; the processing module is connected with the alarm module; the alarm module is connected with the communication module; the drive module is connected with the charge and discharge control module; the charge and discharge control module is additionally connected with the battery, and connected in parallel with the voltage and current detection module. The anti-theft alarm component also includes an image acquisition module; the image acquisition module is connected to the alarm module.

The beneficial effects produced by the present invention are: the anti-theft and anti-moisture electric meter of the present invention, the meter box is provided with a protective device for covering the transparent glass window on the box cover; the protective device includes a lateral movement locking buckle plate, a shielding baffle, and a traction electromagnet And return spring; the traction electromagnet is electrically controlled to move the moving block downwards, the shielding plate is stuck in the rectangular socket of the horizontally moving locking buckle plate, and the horizontally moving locking buckle plate locks the shielding plate; the traction electromagnet loses power and the moving block Move upward; the shielding plate is separated from the rectangular socket of the traverse locking buckle plate. At this time, the shielding plate can be opened, and the electromagnet is connected to the controller; the controller is connected to the mobile control terminal through a wireless transceiver; a special mobile control is required to open the meter. Terminal, to avoid theft of electricity meters. The invention has simple structure and convenient installation, avoids the hidden dangers of electricity consumption and electricity theft caused by the exposure of the electricity meter wiring, can effectively protect the electricity meter, and can prevent water meter from dust and rust, and can also play an effective role Anti-theft effect.
