[0008] By adopting the above technical solution, the electric energy meter body is wrapped by a housing and a cover body, and the housing and the cover body are detachably connected through a locking mechanism, the locking mechanism is controlled by an infrared receiver and a control panel, and the notch of the installation slot is covered by a covering mechanism. Under normal circumstances, it is not easy for users or outsiders to open the cover body and change the parameters or hardware of the electric energy meter body.

The slide plate 17 is slidingly connected to the sliding frame 161 through the sliding groove and is used to close or open the through hole of the sliding frame 161. The piston rod of the second electric push rod 163 extends into the sliding groove and is fixedly connected to the top of the slide plate 17.

[0055] The implementation principle of an anti-electricity theft electric energy meter is as follows: the locking mechanism is controlled by the infrared receiver 5 and the control board 6, and the notch of the installation slot 4 is covered by the covering mechanism. Under normal circumstances, it is not easy for users or outsiders to open the cover body 3 and change the parameters or hardware of the electric energy meter body 1. When the worker needs to open it, he needs to press the control levers 7 in the middle row in sequence to expose the notch of the installation slot 4, and then send an infrared signal to the installation slot 4 through the remote control pre-paired with the infrared receiver 5. When the infrared receiver 5 receives the corresponding control instruction, the control board 6 is driven by the electric signal to control the motor 131. The output shaft of the motor 131 rotates to drive the gear 132 to rotate, so that the rack 133 drives the locking rod 15 away from the locking slot, and then unlocks the lock between the housing 2 and the cover body 3, so that the electric energy meter body 1 can be maintained. This opening method of the cover body 3 is relatively concealed and the safety is improved, so that it is not easy for users or outsiders to open the cover body 3, thereby reducing the occurrence of electricity theft, thereby improving the anti-electricity theft performance of the electric energy meter.

[0056] Reference Figure 5 The present application discloses an anti-electricity theft method for an electric energy meter.

[0057] A method for preventing electricity theft of an electric energy meter, comprising:

[0058] S1, obtains the infrared signal from the remote control.

[0059] Specifically, before obtaining the infrared signal, it is necessary to press the corresponding control lever to open the installation slot, the second electric push rod controls the slide plate to slide out of the slot, and then use the pre-paired remote control to send the infrared signal so that the infrared receiver can obtain the infrared signal.

[0060] S2, identifying the signal type of the infrared signal and generating instruction type information.

[0061] The command type information includes a dust removal command and an unlock command.

[0062] Specifically, the infrared receiver receives and decodes the infrared signal, identifies the signal type, and transmits it to the control board in the form of an electrical signal. The control board generates instruction type information accordingly.

[0063] S3, generating control information according to the corresponding instruction type information.

[0064] The control information includes dust removal control and unlocking control. The dust removal control is used to control the first electric push rod and the second electric push rod. The unlocking control is used to control the motor to drive the gear to rotate through the output shaft of the motor to achieve unlocking.

[0065] Specifically, the control board further processes the instruction type information into control information to facilitate the control of the relevant drive components. When the control information is dust removal control, the first electric push rod and the second electric push rod are controlled to perform dust removal and dust prevention; when the control information is unlocking control, the motor is controlled to perform unlocking.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
